Description

The present invention relates to a component supply device, a component mounting machine equipped with the same, and a component supply method.

Conventionally, component mounters for mounting electronic components such as radial components onto a board have been known (for example, see Patent Document 1). The component mounter of Patent Document 1 includes a component supply device that supplies components, and a component mounting mechanism that mounts the components supplied from the component supply device onto the board. The component supply device has a transport path for transporting components, and transports the components along the transport path toward a predetermined pick-up position. The component mounting mechanism picks up the components at the pick-up position with a suction head, and mounts the picked-up components onto the board.

Patent No. 5864294

However, problems with part precision and other factors can cause the posture of the part to vary at the pick-up position. If the posture of the part at the pick-up position varies, the part mounting mechanism will not be able to pick up the part properly, increasing the likelihood of an error. As a result, the efficiency of part supply decreases.

It can be said that there is room for improvement in terms of improving the efficiency of component supply, including the component mounter of Patent Document 1.

The object of the present invention is therefore to provide a component supply device that can solve the above problems and improve the efficiency of supplying components, a component mounter equipped with the same, and a component supply method.

To achieve the above object, the component supply device of the present invention comprises a transport path for transporting components in a transport direction toward a pick-up position, and a posture correction mechanism for correcting the posture of the components on the transport path, the posture correction mechanism comprising a movable guide having a contact portion capable of contacting the leads of the components and movable in a lateral direction intersecting the transport direction, and a fixed guide provided in a position facing the movable guide across the leads of the components, the movable guide comprising a first contact portion that contacts a first lead on the rear side of the components and a second contact portion that contacts a second lead on the front side of the components, the first contact portion having a first inclined portion inclined to tilt the components forward, and the second contact portion having a second inclined portion inclined to tilt the components backward.

The component mounter of the present invention also includes the component supply device and a component mounting mechanism that picks up a component at the pickup position on the component supply device and inserts the leads of the picked-up component into a board to mount the component on the board.

The component supply method of the present invention includes a transport step of transporting a component in a transport direction toward a pick-up position, and a posture correction step of correcting the posture of the component. The posture correction step uses a posture correction mechanism including a movable guide having a contact portion capable of contacting the lead of the component and movable in a lateral direction intersecting the transport direction, and a fixed guide provided in a position facing the movable guide across the lead of the component, to perform a first contact step of contacting a first contact portion of the movable guide with a first lead on the rear side of the component and tilting the component forward with a first inclined portion provided on the first contact portion, and a second contact step of contacting a second contact portion of the movable guide with a second lead on the front side of the component and tilting the component backward with a second inclined portion provided on the second contact portion.

The present invention can improve parts supply efficiency.

Below, exemplary embodiments of a component supply device and a component mounting machine including the same, as well as a component supply method according to the present invention, will be described with reference to the accompanying drawings. The present invention is not limited to the specific configurations of the following embodiments, and configurations based on similar technical ideas are included in the present invention.

(Embodiment 1)
1 shows a component mounter 1 according to a first embodiment of the present invention. The component mounter 1 is a device that mounts components 3 on a board 2. The component mounter 1 includes a base 11, a board transport mechanism 12, a plurality of component supply devices 13, a component camera 14, a component mounting mechanism 15, and a control unit 16. For ease of explanation, the left-right direction of the component mounter 1 as viewed from an operator OP is defined as the X-axis direction, the front-rear direction is defined as the Y-axis direction, and the up-down direction is defined as the Z-axis direction.

In FIG. 1, the board transport mechanism 12 transports the board 2 along the X-axis direction using a pair of conveyor mechanisms 12a, and positions it at a predetermined work position near the center of the base 11. A plurality of component supply devices 13 are arranged side by side on a dolly 11D attached to the base 11.

In FIG. 1, each of the component supply devices 13 has a component supply port 13K at its tip, and continuously supplies components 3 to a pickup position 13P (FIG. 2) directly below the component supply port 13K. In the first embodiment, the components 3 supplied by the component supply device 13 are radial components with leads (radial taping components), and as shown in FIG. 3, have a cylindrical body 3B and two leads 3R extending downward from the body 3B.

In FIG. 1, the component camera 14 is provided in the area between the board transport mechanism 12 and the component supply device 13. The component camera 14 has an imaging field of view facing upward, and captures an image of the component 3 picked up by the component mounting mechanism 15 from below.

In FIG. 1, the component mounting mechanism 15 includes a head moving mechanism 21 provided on the base 11, and a mounting head 22 that is moved by the head moving mechanism 21. The head moving mechanism 21 includes a fixed table 21a, a moving table 21b, and a moving plate 21c. The fixed table 21a is fixed to the base 11, and the moving table 21b is provided so as to be movable in the Y-axis direction along the fixed table 21a. The moving plate 21c is provided so as to be movable in the X-axis direction along the moving table 21b, and the mounting head 22 is attached to the moving plate 21c. The mounting head 22 is movable in the horizontal direction by the movement of the moving table 21b and the moving plate 21c.

In FIG. 1, the mounting head 22 is equipped with multiple suction nozzles 22a. Each suction nozzle 22a extends downward, with a component suction port at its lower end, and is configured to be able to move up and down along the Z-axis direction. The mounting head 22 is equipped with a suction control mechanism 22b, which is connected to a vacuum source (not shown). The suction control mechanism 22b controls the vacuum pressure supplied from the vacuum source to generate a vacuum suction force at the component suction port of each suction nozzle 22a.

The head movement mechanism 21 moves the mounting head 22 to above the component supply port 13K of the component supply device 13, then lowers the suction nozzle 22a and brings the body 3B of the component 3 into contact with the lower end of the suction nozzle 22a to vacuum-suck it. This picks up the component 3 supplied to the pick-up position 13P (Figures 2 and 3).

The control unit 16 is a component for controlling the operation of the component mounter 1. The control unit 16 is electrically connected to each component of the component mounter 1 and controls the operation of each component. The control unit 16 has, for example, a microcomputer. The control unit 16 displays information related to the operating status of the component mounter 1 on the touch panel 101 and accepts input from the operator OP.

In FIG. 2, each component supply device 13 has a base portion 31 connected to the trolley 11D (FIG. 1), and a cover portion 32 attached to the base portion 31. A component holding tape 4 is provided within the area covered by the cover portion 32 on the base portion 31. The component holding tape 4 is a tape-like member that holds the leads 3R of multiple components 3, and travels at a pitch in the conveying direction A along the Y-axis direction on a conveying path TR provided inside the cover portion 32.

As shown in FIG. 2, a first drive source 34 for pitch-traveling the component holding tape 4 is provided inside the component supply device 13. In this embodiment, the first drive source 34 is a cylinder having an output shaft 35, and drives the output shaft 35 back and forth along the conveying direction A. The first drive source 34 is controlled by the control unit 16.

The control unit 16 controls the first drive source 34 to perform an intermittent feed operation of the part 3, and intermittently supplies the part 3 to the pickup position 13P.

The component supply device 13 shown in FIG. 2 is provided with at least two component correction mechanisms 40, 42 as mechanisms for correcting the posture, position, lead pitch, etc. of the component 3 transported along the transport path TR. In FIG. 2, the approximate locations of the component correction mechanisms 40, 42 are indicated by dotted lines, and the specific configuration is not shown.

The first part correction mechanism 40 is a mechanism provided on the upstream side A1 of the pickup position 13P in the conveying direction A, and the second part correction mechanism 42 is a mechanism provided on the downstream side A2 of the pickup position 13P in the conveying direction A of the first part correction mechanism 40.

By providing the component correction mechanisms 40, 42 in the component supply device 13, the posture and position of the component 3 at the pick-up position 13P can be stabilized, improving the success rate when the component mounting mechanism 15 picks up the component 3. In addition, when the lead pitch of the component 3 is adjusted, the lead 3R of the component 3 picked up by the component mounting mechanism 15 can be inserted with high precision into the insertion hole of the board 2. In this way, the efficiency with which the component supply device 13 supplies the component 3 can be improved.

The configuration and operation of each of the part correction mechanisms 40 and 42 will be explained below with reference to Figures 4 and subsequent figures.

(First component correction mechanism 40: posture correction mechanism 40A)
4 and 5 are a perspective view and a plan view of the first component correction mechanism 40 in the embodiment 1. The first component correction mechanism 40 in the embodiment 1 is a posture correction mechanism 40A for correcting the posture of the component 3 midway along the transport path TR. In the following, the first component correction mechanism 40 will be described as the posture correction mechanism 40A.

The posture correction mechanism 40A includes a movable guide 44, a fixed guide 46, a second drive source 48, and a cam mechanism 50. The movable guide 44, the fixed guide 46, the second drive source 48, and the cam mechanism 50 are all attached to the device main body 43 that forms the transport path TR.

The movable guide 44 and the fixed guide 46 are members that sandwich the lead 3R of the component 3 between them to correct the position of the component 3 in the transport direction A.

The movable guide 44 is a guide configured to be movable in a lateral direction B, which is a direction intersecting the conveying direction A. In the first embodiment, the lateral direction B is a horizontal direction perpendicular to the conveying direction A, and corresponds to the X-axis direction. The fixed guide 46 is disposed at a position facing the movable guide 44 across the conveying path TR, and is fixed to the device main body 43.

The area between the movable guide 44 and the fixed guide 46 includes correction positions P1 and P2 for correcting the posture of the part 3. The first correction position P1 is located on the upstream side A1, and the second correction position P2 is located on the downstream side A2. After stopping at the first correction position P1, the part 3 is fed one pitch and stops at the second correction position P2.

The movable guide 44 and the fixed guide 46 have the function of changing the inclination of the part 3 at the first correction position P1 to the forward side (downstream side A2), and further have the function of changing the inclination of the part 3 at the second correction position P2 to the rear side (upstream side A1). By changing the inclination of the part 3 to both the forward and rear sides, the part 3 can be corrected to an upright position while taking into account the springback of the lead 3R, regardless of whether the part 3 is tilted forward or backward. Details will be described later.

The second drive source 48 is a drive source for reciprocating the movable guide 44 in the lateral direction B. The second drive source 48 is provided as a drive source different from the first drive source 34 (FIG. 2) described above, and has an output shaft 49 that can be driven along the conveying direction A. The second drive source 48 in the first embodiment is a cylinder that drives the output shaft 49 back and forth. A cam mechanism 50 is connected to the output shaft 49 of the second drive source 48.

The cam mechanism 50 is a mechanism for converting the driving force of the second driving source 48 along the conveying direction A into a driving force in the horizontal direction B and transmitting it to the movable guide 44. The cam mechanism 50 includes a cam 54 connected to the output shaft 49, and a cam follower 56 that engages with the cam 54 and is connected to the movable guide 44. A cam groove 55 is formed at the tip of the cam 54, and a protrusion 58 of the cam follower 56 engages with the cam groove 55. The cam groove 55 has an oblique shape in a plan view such that the cam follower 56 moves along the horizontal direction B when the cam 54 moves back and forth along the conveying direction A. The cam follower 56 is attached to the device main body 43 in a state in which it can move in the horizontal direction B but is restricted from moving back and forth.

With this configuration, when the second drive source 48 drives the output shaft 49 back and forth along the conveying direction A, the cam 54 moves back and forth, and the cam follower 56 engaged with the cam 54 moves back and forth in the lateral direction B. This allows the movable guide 44 connected to the cam follower 56 to move back and forth in the lateral direction B. Figures 4 and 5 show an example of the state in which the movable guide 44 is closest to the fixed guide 46 (during operation).

Next, the configuration of the movable guide 44 and the fixed guide 46 will be explained using Figures 6 to 9.

Figures 6 and 7 are perspective views showing the movable guide 44, the fixed guide 46, and the component holding tape 4, and Figures 8 and 9 are plan views corresponding to Figures 6 and 7, respectively. Figures 6 and 8 show the movable guide 44 approaching the fixed guide 46, while Figures 7 and 9 show an exaggerated view of the movable guide 44 separated from the fixed guide 46. Other components including the component 3 are not shown in Figures 6 to 9.

As shown in Figures 7 and 9, the movable guide 44 has two contact portions 60 and 62. The contact portions 60 and 62 are portions for contacting the leads 3R of the component 3 at the correction positions P1 and P2, respectively, to change the posture of the component 3. Both contact portions 60 and 62 have a shape that protrudes in the lateral direction B toward the fixed guide 46 on the movable guide 44.

Recesses 64, 66 are formed at both ends of the fixed guide 46. The recesses 64, 66 are recesses for accommodating one end of the contact parts 60, 62, respectively, when the contact parts 60, 62 approach each other.

As shown in Figures 7 and 9, the first contact portion 60 has a first inclined portion 60A and a first non-inclined portion 60B, and the second contact portion 62 has a second inclined portion 62A and a second non-inclined portion 62B.

The inclined portions 60A and 62A are both surfaces that are inclined with respect to both the conveying direction A and the lateral direction B in a plan view. The non-inclined portions 60B and 62B are both surfaces that extend in the lateral direction B in a plan view.

The first inclined portion 60A is a portion that comes into contact with the lead 3R of the component 3 at the first correction position P1 and changes the posture of the component 3 to the forward side (downstream side A2). The first inclined portion 60A comes into contact with the rearward (upstream side A1) lead 3R of the two leads 3R of the component 3. The first inclined portion 60A in the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 46 as it approaches the downstream side A2 in the conveying direction A.

The second inclined portion 62A is a portion that comes into contact with the lead 3R of the component 3 at the second correction position P2 and changes the posture of the component 3 to the rear side (upstream side A1). The second inclined portion 62A comes into contact with the lead 3R on the front side (downstream side A2) of the two leads 3R of the component 3. The second inclined portion 62A in the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 46 as it approaches the upstream side A1 in the conveying direction A.

The first non-inclined portion 60B is a portion that extends in the lateral direction B on the inside of the first inclined portion 60A and is connected to the first inclined portion 60A. The first non-inclined portion 60B receives the lead 3R of the component 3 after it comes into contact with the first inclined portion 60A, and restricts its movement toward the upstream side A1.

The second non-inclined portion 62B is a portion that extends in the lateral direction B on the inside of the second inclined portion 62A and is connected to the second inclined portion 62A. The second non-inclined portion 62B receives the lead 3R of the component 3 after it comes into contact with the second inclined portion 62A, and restricts its movement toward the downstream side A2.

The movable guide 44 further has a connection portion 68. The connection portion 68 is a portion that connects the first non-inclined portion 60B and the second non-inclined portion 62B, and extends along the transport direction A. The connection portion 68 is recessed inward from the first non-inclined portion 60B and the second non-inclined portion 62B, and faces the fixed guide 46 in the lateral direction B. The connection portion 68, together with the fixed guide 46, restricts the movement of the leads 3R of the component 3 at the correction positions P1 and P2 in the lateral direction B. The connection portion 68 of the first embodiment has a length that includes both the first correction position P1 and the second correction position P2.

A method for correcting the inclination of the part 3 in the transport direction A using the posture correction mechanism 40A having the above-mentioned configuration will be described with reference to Figures 10A to 10D and Figures 11A to 11D. Figures 10A to 10D are figures for explaining the correction method when the part 3 is inclined backward, and Figures 11A to 11D are figures for explaining the correction method when the part 3 is inclined forward.

In the example shown in Figures 10A and 10B, the component 3 (shown by a dotted line) that has been transported to the first correction position P1 is in a state in which it has fallen backward (upstream side A1) with respect to the upright posture based on the vertical axis Q0. The central axis Q1 of the component 3 is inclined backward with respect to the vertical axis Q0. In this state, when the second drive source 48 (Figures 4 and 5) is driven to drive the movable guide 44 in the lateral direction B so as to approach the fixed guide 46, the first inclined portion 60A of the first contact portion 60 contacts the rear lead 3R of the component 3 at the first correction position P1 (first contact step). The first inclined portion 60A is inclined so as to move away from the fixed guide 46 as it approaches the downstream side A2 in the transport direction A, and as the movable guide 44 advances, the first inclined portion 60A urges the lead 3R toward the downstream side A2 while pressing it against the fixed guide 46. This changes the position of part 3 to the forward side C1 (downstream side A2) (shown by the solid line).

As shown in FIG. 10A, at the first correction position P1, the shape and position of the first inclined portion 60A are set so that the central axis Q2 of the component 3 is inclined forward with respect to the vertical axis Q0. As described below, taking into consideration the occurrence of springback in the lead 3R of the component 3, the first inclined portion 60A corrects the posture of the component 3 to a position that is tilted forward from the upright posture.

After coming into contact with the first inclined portion 60A, the lead 3R of the component 3 comes into contact with the first non-inclined portion 60B located inside the first inclined portion 60A shown in Figures 7 to 9. When springback occurs in the lead 3R of the component 3 and it attempts to return to the upstream side A1, the first non-inclined portion 60B receives the lead 3R and restricts its movement toward the upstream side A1.

The lead 3R of the component 3 is positioned in the area between the connection portion 68 provided on the inside of the first non-inclined portion 60B and the fixed guide 46. This restricts the movement of the lead 3R in the lateral direction B.

Figures 10C and 10D show the state in which the movable guide 44 has been retracted from the state shown in Figures 10A and 10B. As shown in Figures 10C and 10D, the part 3 in the first correction position P1 was tilted slightly forward with respect to the vertical axis Q0 (shown by the dotted line), but when contact with the first contact portion 60 is released and springback occurs in the lead 3R of the part 3, the lead 3R naturally returns to the upstream side A1. The tilt of the part 3 is changed to the rear side C3 (upstream side A1) (shown by the solid line).

In the first embodiment, taking into account the springback of the lead 3R, the target posture for correcting the posture of the part 3 by the first inclined portion 60A is set so that the part 3 is in a generally upright posture after springback and the central axis Q3 is generally aligned with the vertical axis Q0.

The part 3 that has been corrected to an upright position at the first correction position P1 is then sent in the conveying direction A (conveying step) and stops at the second correction position P2. The part 3 that has stopped at the second correction position P2 is shown in Figures 10A and 10B.

As shown in Figures 10A and 10B, the component 3 stopped at the second correction position P2 is in a generally upright position (shown by dotted lines), and when the movable guide 44 is driven by the second drive source 48 in a direction approaching the fixed guide 46, the second inclined portion 62A of the second contact portion 62 comes into contact with the lead 3R on the front side of the component 3 (second contact step). This changes the position of the component 3 to the rear side C2 (upstream side A1) (shown by solid lines).

Regarding the second correction position P2, the springback of the lead 3R of the component 3 is also taken into consideration, and the target posture of the component 3 after posture correction by the second inclined portion 62A is set to a position where the central axis Q4 of the component 3 is inclined toward the rear side C2 from the vertical axis Q0.

When the movable guide 44 is then retracted, as shown in Figures 10C and 10D, the part 3, which was tilted slightly backward with respect to the vertical axis Q0 (shown by the dotted line), springs back in the lead 3R of the part 3, and the tilt of the part 3 naturally changes to the forward side C4 (downstream side A2) (shown by the solid line). As with the first correction position P1, the part 3 after springback assumes a generally upright position, and the central axis Q5 of the part 3 generally coincides with the vertical axis Q0.

As described above, the part 3 that has been corrected to an upright position at the first correction position P1 is corrected again to an upright position at the second correction position P2. In this way, if the part 3 sent to the first correction position P1 has fallen backward (upstream side A1), the posture correction mechanism 40A is used to correct the posture of the part 3 in two stages, thereby correcting the part 3 to an upright posture.

Next, a method for correcting the posture of part 3 when it has fallen forward (downstream side B2) will be described with reference to Figures 11A to 11D.

In the example shown in Figures 11A and 11B, the part 3 (shown by a solid line) that has been transported to the first correction position P1 is in a state in which it is tilted forward (downstream A2) with respect to the upright posture based on the vertical axis Q0. The central axis Q6 of the part 3 is inclined forward with respect to the vertical axis Q0. In this state, when the second drive source 48 (Figures 4 and 5) is driven to drive the movable guide 44 in the lateral direction B so as to approach the fixed guide 46, if the part 3 is significantly tilted forward as shown in Figures 11A and 11B, the first inclined portion 60A of the first contact portion 60 does not contact the lead 3R on the rear side of the part 3, and the posture of the part 3 is not corrected (arrow C1). In this case, even if the movable guide 44 is retracted, no springback occurs in the lead 3R of the part 3, so the posture of the part 3 is maintained in a state inclined forward as shown in Figures 11C and 11D.

On the other hand, if the inclination of the component 3 is small, when the movable guide 44 approaches the fixed guide 46, the first inclined portion 60A comes into contact with the rear lead 3R of the component 3, as in the case shown in Figures 10A to 10D, and the position of the component 3 is corrected to the front side C1.

The component 3, whose posture has not been corrected at the first correction position P1, is then sent to the second correction position P2. As shown in Figures 11A and 11B, the component 3 stopped at the second correction position P2 is tilted significantly forward (shown by the dotted line), and when the movable guide 44 is driven by the second drive source 48 in a direction approaching the fixed guide 46, the second inclined portion 62A of the second contact portion 62 comes into contact with the lead 3R on the forward side of the component 3. This changes the posture of the component 3 to the rear side C5 (upstream side A1) (shown by the solid line).

As in the case shown in Figures 10A to 10D, the target posture of the part 3 after posture correction by the second inclined portion 62A is set so that the central axis Q7 of the part 3 is inclined toward the rear side C5 of the vertical axis Q0, taking into account the springback of the lead 3R of the part 3. When the movable guide 44 is then retracted, as shown in Figures 11C and 11D, springback occurs in the lead 3R of the part 3, and the posture of the part 3 is naturally changed to the forward side C6 (downstream side A2) (shown by the solid line).

As described above, even if the part 3 is tilted forward, the posture correction mechanism 40A can be used to correct the part 3 to an upright posture. In this case, if the part 3 is tilted significantly, it is not corrected to an upright posture at the first correction position P1, but is corrected to an upright posture at the second correction position P2. If the part 3 is tilted slightly, it is corrected to an upright posture at both the first correction position P1 and the second correction position P2. In this way, the posture of the part 3 can be corrected to an upright posture, just as when the part 3 is tilted backward.

According to the operations shown in Figures 10A to 10D and 11A to 11D, the orientation of the part 3 is changed to the forward side at the first correction position P1, and the orientation of the part 3 is changed to the backward side at the second correction position P2. This makes it possible to correct the part 3 to an upright orientation regardless of whether the part 3 is tilted forward or backward.

Then, the posture correction mechanism 40A performs posture correction on the components 3 that stop sequentially at the correction positions P1 and P2. This allows the posture of the components 3 to be uniformly corrected on the way to the pick-up position 13P, and the posture of the components 3 that reach the pick-up position 13P can be stabilized. In this way, the success rate of the component mounting mechanism 15 picking up the components 3 at the pick-up position 13P can be improved, and the efficiency of supplying the components 3 by the component supply device 13 can be improved.

(Actions and Effects Related to Posture Correction Mechanism 40A)
As described above, the component supply device 13 of the first embodiment includes a transport path TR that transports the component 3 in the transport direction A toward the pick-up position 13P, and a posture correction mechanism 40A that corrects the posture of the component 3 on the transport path TR. The posture correction mechanism 40A includes a movable guide 44 that has contact portions 60, 62 that can contact the leads 3R of the component 3 and can move in a lateral direction B that intersects with the transport direction A, and a fixed guide 46 that is disposed in a position facing the movable guide 44 with the leads 3R of the component 3 in between. The movable guide 44 includes a first contact portion 60 that contacts the rear lead (first lead) 3R of the component 3, and a second contact portion 62 that contacts the front lead (second lead) 3R of the component 3. The first contact portion 60 has a first inclined portion 60A inclined to tilt the component 3 toward the forward side (downstream side A2), and the second contact portion 62 has a second inclined portion 62A inclined to tilt the component 3 toward the rear side (upstream side A1).

With this configuration, the two inclined portions 60A and 62A can change the orientation of the part 3 to either the forward or backward side, so that the orientation of the part 3 can be corrected even if the orientation of the part 3 is tilted either forward or backward. This improves the efficiency with which the part supply device 13 supplies the part 3.

In addition, according to the component supply device 13 of embodiment 1, the first inclined portion 60A has a shape that is inclined in a direction away from the fixed guide 46 as it approaches the downstream side A2 of the conveying direction A, and the second inclined portion 62A has a shape that is inclined in a direction away from the fixed guide 46 as it approaches the upstream side A1 of the conveying direction A. With this configuration, the two inclined portions 60A, 62A can change the posture of the component 3 toward the desired target posture.

Furthermore, according to the component supply device 13 of embodiment 1, the first contact portion 60 further has a first non-inclined portion 60B extending along the horizontal direction B inside the first inclined portion 60A. Furthermore, the second contact portion 62 further has a second non-inclined portion 62B extending along the horizontal direction B inside the second inclined portion 62A. With this configuration, the non-inclined portions 60B, 62B can restrict the movement of the leads 3R of the component 3 in the transport direction A after contacting the inclined portions 60A, 62A, and the posture of the component 3 can be accurately corrected.

Furthermore, according to the component supply device 13 of embodiment 1, the posture correction mechanism 40A has a connection portion 68 that extends along the transport direction A to connect the first non-inclined portion 60B and the second non-inclined portion 62B. With this configuration, the lead 3R of the component 3 can be sandwiched between the connection portion 68 and the fixed guide 46 to restrict movement in the lateral direction B, and the tilt of the component 3 in the transport direction A can be accurately corrected.

In addition, according to the component supply device 13 of embodiment 1, the first contact portion 60 is provided on the upstream side A1 of the second contact portion 62 in the conveying direction A. With this configuration, the two inclined portions 60A, 62A can be formed facing inward, thereby making it possible to reduce the size of the movable guide 44.

The component supply device 13 of the first embodiment further includes a control unit 16. The control unit 16 controls the first drive source 34 to perform the feed operation of the components 3 intermittently, and stops each component 3 at both the first correction position P1 where the first contact portion 60 contacts the rear lead (first lead) 3R and the second correction position P2 where the second contact portion 62 contacts the front lead (second lead) 3R. With this configuration, it is possible to perform both corrections to change the posture of each component 3 to the forward side and corrections to change the posture of the component 3 to the backward side, and the posture of the component 3 can be corrected regardless of whether the component 3 is tilted forward or backward.

The component supply device 13 of the first embodiment also includes a first drive source 34 for feeding the component 3 along the transport path TR, and a second drive source 48 for driving the movable guide 44 in the lateral direction B. With this configuration, the feeding operation of the component 3 and the reciprocating drive of the movable guide 44 can be performed independently.

In addition, according to the component supply device 13 of the first embodiment, the first drive source 34 performs the feed operation of the component 3 intermittently, and the second drive source 48 drives the movable guide 44 while the feed of the component 3 by the first drive source 34 is stopped. With this configuration, it is possible to prevent the movable guide 44 from interfering with the component 3.

The component mounter 1 of the first embodiment also includes a component supply device 13 having an attitude correction mechanism 40A, and a component mounting mechanism 15. The component mounting mechanism 15 picks up a component 3 at a pickup position 13P in the component supply device 13, and inserts the leads 3R of the picked-up component 3 into the board 2 to mount the component 3 on the board 2. A component mounter 1 configured in this way can achieve the same effects as a component supply device 13 having an attitude correction mechanism 40A.

The component supply method of the first embodiment also includes a transport step of transporting the component 3 in the transport direction A toward the pickup position 13P, and a posture correction step of correcting the posture of the component 3. The posture correction step includes a first contact step and a second contact step using a posture correction mechanism 40A including a movable guide 44 and a fixed guide 46. The first contact step includes contacting the first contact portion 60 of the movable guide 44 with the lead 3R (first lead) on the rear side of the component 3, and tilting the component 3 forward (downstream side A2) by the first inclined portion 60A provided on the first contact portion 60. The second contact step includes contacting the second contact portion 62 of the movable guide 44 with the lead 3R (second lead) on the front side of the component 3, and tilting the component 3 backward by the second inclined portion 62A provided on the second contact portion 62.

According to this method, the orientation of the part 3 can be changed to either the forward or backward direction, so that the orientation of the part 3 can be corrected even if the orientation of the part 3 is tilted either forward or backward. This improves the efficiency of supplying the part 3.

(Modifications Related to Posture Correction Mechanism 40A)
In the first embodiment, a case where one set of the movable guide 44 and the fixed guide 46 is provided has been described, but the present invention is not limited to this case. For example, two or more sets of the movable guide 44 and the fixed guide 46 may be provided at intervals in the conveying direction A. In the first embodiment, a case where the posture of the part 3 after springback is corrected to be approximately upright at both the first correction position P1 and the second correction position P2 has been described, but the present invention is not limited to this case. For example, the posture of the part 3 may be corrected so that the posture of the part 3 is finally upright by correcting the tilt to a large extent toward the front side at the first correction position P1 and correcting the tilt to a small extent toward the rear side at the second correction position P2. That is, the posture of the part 3 may be corrected so that it does not approach the upright posture at the first correction position P1. In this case, another set of the movable guide 44 and the fixed guide 46 may be provided on the downstream side B2, and in the other set, the tilt to a large extent toward the rear side may be corrected at the first correction position and the tilt to a small extent toward the front side may be corrected at the second correction position. As a result, even if the part 3 is tilted forward or backward, the posture of the part 3 can be brought closer to an upright posture by providing two sets of movable guides 44 and fixed guides 46 to correct the tilt of the part 3.

In addition, in the first embodiment, a case has been described in which one movable guide 44 integrally forms the first contact portion 60 and the second contact portion 62, but this is not limited to the case, and they may be configured as separate bodies. In other words, a first movable guide forming the first contact portion 60 and a second movable guide forming the second contact portion 62 may be provided.

(Second component correction mechanism 42)
Next, the second component correction mechanism 42 provided at the pickup position 13P of the component supply device 13 shown in FIG. 2 will be described with reference to FIGS. 12 to 24B.

Figures 12 and 13 are perspective views of the second part correction mechanism 42 in embodiment 1, and Figure 14 is a plan view of the second part correction mechanism 42. The second part correction mechanism 42 in embodiment 1 is a posture correction mechanism 42A for correcting the posture of the part 3 at the pick-up position 13P. Below, the second part correction mechanism 42 will be described as the posture correction mechanism 42A.

As described above, the posture of the component 3 is first corrected on the upstream side A1 of the pickup position 13P using the posture correction mechanism 40A. The component supply device 13 of embodiment 1 further includes a posture correction mechanism 42A at the pickup position 13P in order to more accurately hold the component 3 in an upright posture at the pickup position 13P.

As described below, in the component supply device 13 of embodiment 1, the operation of cutting the leads 3R of the component 3 at the pick-up position 13P is performed, so the posture of the component 3 is easily distorted at the pick-up position 13P. In response to this, the component supply device 13 of this embodiment is provided with a posture correction mechanism 42A at the pick-up position 13P, and performs the cutting operation of the leads 3R while maintaining the posture of the component 3 in an upright posture. This makes it possible to stabilize the posture of the component 3 even after the cutting operation.

The posture correction mechanism 42A shown in Figures 12 to 14 includes a first regulating unit 100, a second regulating unit 102, a first driving source 34, a cam mechanism 106, and a lead cutting unit 107. The first regulating unit 100, the second regulating unit 102, the first driving source 34, the cam mechanism 106, and the lead cutting unit 107 are all attached to the device main body 43 that forms the transport path TR.

The first regulating unit 100 and the second regulating unit 102 are members for regulating the movement of the component 3 at the pickup position 13P and maintaining the component 3 in an upright position. The specific configurations of the first regulating unit 100 and the second regulating unit 102 will be described later, but the first regulating unit 100 has a function of regulating the movement of the component 3 in the lateral direction B, and the second regulating unit 102 has a function of regulating the movement of the component 3 in the forward and backward directions along the transport direction A.

By providing the first restricting portion 100 and the second restricting portion 102, the movement of the component 3 in the horizontal direction (XY axis direction) can be restricted, and the component 3 at the pickup position 13P can be held in an upright position with high precision. This allows the leads 3R to be cut while the position of the component 3 is maintained.

In the posture correction mechanism 42A of the first embodiment, the first regulating unit 100 is fixed to the device body 43, and the second regulating unit 102 is attached to the device body 43 in a form that allows it to move in the lateral direction B. The second regulating unit 102 is driven by the first drive source 34 (FIG. 12) for performing the feed operation of the part 3.

The first driving source 34 is a driving source for pitch-feeding the component holding tape 4 shown in FIG. 2, and is also used as a driving source for driving the second regulating portion 102 in the lateral direction B. The output shaft 35 of the first driving source 34 is connected to the cam mechanism 106.

The cam mechanism 106 is a mechanism for converting the driving force of the first driving source 34 along the conveying direction A into a driving force in the lateral direction B and transmitting it to the second regulating unit 102. The cam mechanism 106 includes a cam 108 connected to the output shaft 35, and a cam follower 110 that engages with the cam 108 and is connected to the second regulating unit 102. The cam 108 is formed with a cam groove 109, and a protrusion 111 of the cam follower 110 engages with the cam groove 109. The cam groove 109 has an oblique shape in a plan view such that the cam follower 110 moves along the lateral direction B when the cam 108 moves back and forth along the conveying direction A. The cam follower 110 is attached to the device main body 43 in a state in which it can move in the lateral direction B but is restricted from moving back and forth.

With this configuration, when the first drive source 34 drives the output shaft 35 back and forth along the conveying direction A, the cam 108 moves back and forth, and the cam follower 110 engaged with the cam 108 moves back and forth in the lateral direction B. This allows the second regulating part 102 connected to the cam follower 110 to move back and forth in the lateral direction B. The second regulating part 102 moves back and forth between a regulating position where it regulates the movement of the part 3, and a retracted position where it is retracted from the part 3. Figures 12 to 14 show an example of the state (during operation) when the second regulating part 102 is in the regulating position.

The lead cutting unit 107 is a member that cuts the leads 3R of the component 3 at the pick-up position 13P. By cutting the leads 3R of the component 3 at the pick-up position 13P, the length of the leads 3R is adjusted in advance to a desired length.

The lead cutting unit 107 has a fixed part 107A and a movable part 107B. The fixed part 107A is a member fixed to the device main body 43, and the movable part 107B is a member configured to be movable back and forth in the lateral direction B by a drive source (not shown). The fixed part 107A and the movable part 107B each have a blade surface (not shown) for cutting the lead 3R of the component 3, and when the movable part 107B approaches the fixed part 107A, the lead 3R of the component 3 is sandwiched between the blade surfaces to cut the lead 3R.

As shown in Figures 12 to 14, a conveying chute 112 is provided on the downstream side A2 of the pick-up position 13P. The conveying chute 112 is a member for conveying the component holding tape 4 further downstream from the pick-up position 13P. Since the components 3 are picked up at the pick-up position 13P, the component holding tape 4 conveyed to the conveying chute 112 does not normally hold the components 3. Exceptionally, there are cases where the components 3 are held on the component holding tape 4 conveyed to the conveying chute 112, such as when the operator OP manually conveys the component holding tape 4 to the downstream side A2 while the operation of the component supply device 13 is stopped.

Next, the specific configuration of the first restricting unit 100 and the second restricting unit 102 will be described with reference to Figures 15 to 17.

Figure 15 is a perspective view showing the peripheral configuration of the first restricting portion 100 and the second restricting portion 102, and Figures 16 and 17 are side views showing the peripheral configuration.

As shown in FIG. 15, the first regulating section 100 includes a first horizontal guide 113 and a second horizontal guide 114. The horizontal guides 113 and 114 are members that clamp the component 3 at the pickup position 13P in the horizontal direction B to regulate its movement. The first horizontal guide 113 is provided on the right side facing the conveying direction A, and the second horizontal guide 114 is provided on the left side facing the conveying direction A. Both horizontal guides 113 and 114 are plate-shaped members that extend along the conveying direction A, and are fixed to positions to the side of the conveying path TR so as not to interfere with the feeding operation of the component 3.

The second regulating portion 102 includes a front guide portion 116 and a rear guide portion 118. The guide portions 116 and 118 are members that sandwich the component 3 at the pick-up position 13P in the front-rear direction to regulate its movement. The front guide portion 116 is disposed in front of the pick-up position 13P (downstream side A2), and the rear guide portion 118 is disposed behind the pick-up position 13P (upstream side A1).

Both the front guide portion 116 and the rear guide portion 118 are connected to the cam follower 110 described above and move integrally along the lateral direction B. As in FIGS. 12 to 14, FIGS. 15 to 17 illustrate a state in which the front guide portion 116 and the rear guide portion 118 are in a restricting position that restricts the movement of the part 3.

The front guide portion 116 in the first embodiment has an L-shape in a plan view. The front guide portion 116 extends toward the downstream side A2 in the conveying direction A, then bends at a right angle and extends along the lateral direction B. The tip side portion of the front guide portion 116 extending along the lateral direction B is positioned to block the front of the part 3, and restricts the movement of the part 3 toward the downstream side A2.

The rear guide portion 118 of the first embodiment has a so-called "hinge" structure. The rear guide portion 118 includes a fixed portion 120, a rotating portion 122, and a retaining portion 124.

The fixed part 120 is a plate-like member fixed to the cam follower 110. The rotating part 122 is a plate-like member that is connected to the fixed part 120 and is configured to be rotatable around the rotation axis X1. The rotating part 122 has the function of preventing interference with the part 3 by rotating around the rotation axis X1 when it comes into contact with the part 3 advancing along the conveying direction A.

The retaining portion 124 is a biasing member that biases the rotating portion 122 in a rotational direction opposite to the rotational force that tends to rotate the rotating portion 122 forward (downstream side A2). By providing the retaining portion 124, it is possible to prevent the rotating portion 122 from rotating forcefully forward due to contact with the component 3, and to stabilize the operation of the rotating portion 122.

Here, the function and operation of the rear guide unit 118 will be described with reference to Figures 18A and 18B. Figure 18A is a side view showing a state in which the part 3 is not in contact with the rotating unit 122, and Figure 18B is a side view showing a state in which the part 3 is in contact with the rotating unit 122 and the rotating unit 122 has rotated.

As shown in FIG. 18A, the rotating part 122 is in a position extending vertically downward when the part 3 is not in contact with it. At this time, the tip 110A of the cam follower 110 abuts the base of the rotating part 122, restricting the movement of the rotating part 122 so that it cannot rotate toward the upstream side A1 (arrow R1). Although the rotating part 122 can rotate toward the downstream side A2 (arrow R2), the pressing part 124 abuts against the rotating part 122 and biases it in the opposite direction (arrow R3), so resistance is generated when the rotating part 122 rotates.

As shown in FIG. 18B, when the part 3 is conveyed in the conveying direction A and comes into contact with the rotating part 122, the rotating part 122 rotates about the rotation axis X1 toward the downstream side A2 (arrow R2) due to contact with the side of the part 3. By rotating the rotating part 122, interference with the part 3 can be prevented.

When the rotating part 122 rotates, the pressing part 124 biases the rotating part 122 in the opposite direction (arrow R3), so the rotating part 122 does not rotate forcefully, but rotates gently while maintaining contact with the side of the part 3. This allows the rotating part 122 to rotate only as far as necessary without colliding with the part 3 (not shown) in front of the part 3 shown in FIG. 18B, stabilizing the operation of the rotating part 122.

The operation of the posture correction mechanism 42A having the above-mentioned configuration will be explained using Figures 19 and subsequent figures.

Figure 19 is a plan view of the second regulating part 102 reciprocating in the lateral direction B using a first drive source 34 having an output shaft 35. In Figure 19, (a) corresponds to a state in which the second regulating part 102 is in the regulating position, and (b) corresponds to a state in which the second regulating part 102 is in the retracted position.

As shown in FIG. 19(a), when the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 downstream A2, the protrusion 111 of the cam follower 110 moves in the lateral direction B along the cam groove 109, and the cam follower 110 moves to the left side of the page. The second regulating part 102 connected to the cam follower 110 also moves toward the left side of the page, moving to a regulating position that regulates the movement of the component 3 at the pickup position 13P.

As shown in FIG. 19B, when the first drive source 34 drives the output shaft 35 to move the cam 108 of the cam mechanism 106 to the upstream side A1, the protrusion 111 of the cam follower 110 moves in the lateral direction B along the cam groove 109, and the cam follower 110 moves toward the right side of the paper. The second restriction portion 102 connected to the cam follower 110 also moves toward the right side of the paper, and moves to a retracted position away from the component 3 at the pickup position 13P.

The first drive source 34 drives the output shaft 35 in the forward and backward directions at a predetermined cycle, so that the state shown in (a) and the state shown in (b) are alternately switched. The second restricting portion 102 moves back and forth between the restricting position and the retracted position, selectively restricting the movement of the part 3 in the forward and backward directions.

In particular, in the first embodiment, a common first drive source 34 is used to perform pitch feeding of the component 3 and drive the second regulating unit 102. For this reason, a rotating unit 122 is provided on the rear guide unit 118 to prevent interference between the feeding operation of the component 3 and the rear guide unit 118, making it possible to perform pitch feeding of the component 3 and drive the second regulating unit 102 in parallel.

Here, the configuration related to the component 3 feeding operation will be described with reference to FIG. 20. FIG. 20 is a schematic side view showing the component holding tape 4 and multiple components 3 held on the component holding tape 4.

As shown in FIG. 20, the component carrier tape 4 has multiple feed holes 126 for pitch feed. A claw portion (not shown) connected to the first drive source 34 engages with the feed holes 126.

When the first driving source 34 drives the claw portion toward the downstream side A2, the claw portion is engaged with the feed hole 126, and the component holding tape 4 is advanced one pitch. On the other hand, when the first driving source 34 drives the claw portion toward the upstream side A1, the engagement between the claw portion and the feed hole 126 is released, and the component holding tape 4 does not move backward but remains stationary. As the first driving source 34 reciprocates the claw portion at a predetermined cycle, the component holding tape 4 is pitch-fed along the conveying direction A, and the feeding operation of the components 3 is performed intermittently.

In particular, in the first embodiment, large radial components are used as the components 3. As shown in FIG. 20, the pitch Y2 of the components 3 is set longer than the pitch Y1 of the feed holes 126 (twice as long in the first embodiment). When the first drive source 34 performs two reciprocating motions, the component holding tape 4 is fed two pitches (Y1 x 2) of the feed holes 126 toward the downstream side A2, and the components 3 are fed one pitch (Y2) toward the downstream side A2.

When the first drive source 34 is driven two times, the component 3 is fed one pitch, whereas the reciprocating motion of the second regulating unit 102 by the same first drive source 34 is two reciprocating motions in the horizontal direction B. In other words, when the component 3 is fed 0.5 pitches, the second regulating unit 102 makes one reciprocating motion in the horizontal direction B, so that the rear guide portion 118 of the second regulating unit 102 comes into contact with the component 3 located in front of the pick-up position 13P.

In response to this, the posture correction mechanism 42A of the first embodiment is provided with the aforementioned rotating part 122 on the rear guide part 118 so that it can rotate when the rotating part 122 comes into contact with the side of the part 3 in front of the pick-up position 13P. As a result, when the same first drive source 34 is used to perform the feeding operation of the part 3 and the reciprocating operation of the second regulating part 102, both operations can be performed in parallel while preventing interference between the part 3 and the second regulating part 102.

The specific operation of the posture correction mechanism 42A having the above-mentioned configuration will be explained using Figures 21A to 24B.

Figures 21A and 21B are side and perspective views showing the state after part 3 at pickup position 13P has been picked up.

As shown in Figures 21A and 21B, the first restricting unit 100 is already restricting the movement of the component 3 in the lateral direction B from the component 3 located behind the pickup position 13P. Meanwhile, the second restricting unit 102 is in the retracted position and is not restricting the movement of the component 3.

When the first drive source 34 drives the output shaft 35 forward (downstream side A2) from the state shown in Figures 21A and 21B, the state shown in Figures 22A and 22B is obtained.

As shown in Figures 22A and 22B, the part 3 is sent 0.5 pitches downstream A2 (transport step), and the second regulating unit 102 is moved in the lateral direction B so as to approach the transport path TR.

Because component 3 is located in front of pickup position 13P, when rotating part 122 of second regulating part 102 moves in lateral direction B, it comes into contact with the side of component 3. Upon contact with component 3, rotating part 122 rotates toward downstream side A2 (arrow R2 in FIG. 22A). This prevents interference between rear guide part 118 and component 3. At this time, rotating part 122 rotates while being biased in the opposite direction by pressing part 124, so it rotates slowly while maintaining contact with the side of component 3 without rotating forcefully toward downstream side A2. This makes it possible to stabilize the rotational movement of rotating part 122.

In this way, even if the part 3 advances 0.5 pitches with one reciprocating drive of the first drive source 34, the feed operation of the part 3 and the reciprocating movement of the second regulating part 102 can be performed in parallel while preventing interference between the rear guide part 118 and the part 3.

When the first drive source 34 drives the output shaft 35 rearward (upstream side A1) from the state shown in Figures 22A and 22B, the state shown in Figures 23A and 23B is obtained.

As shown in Figures 23A and 23B, the part 3 is stationary and does not move, and the second restricting part 102 moves in the lateral direction B away from the transport path TR and moves to the retracted position. The rotating part 122, which has been released from contact with the part 3, returns to a state in which it extends vertically downward.

When the first drive source 34 drives the output shaft 35 forward (downstream side A2) from the state shown in Figures 23A and 23B, the state shown in Figures 24A and 24B is obtained.

As shown in Figures 24A and 24B, the component 3 is sent 0.5 pitches downstream A2 and reaches the pick-up position 13P. The second regulating unit 102 moves in the lateral direction B to approach the transport path TR, but since the component 3 has moved to the pick-up position 13P, the rotating unit 122 does not come into contact with the component 3. The rotating unit 122 enters the area between the component 3 at the pick-up position 13P and the component 3 in front of it.

As explained using FIG. 18A, the rotation of the rotating part 122 toward the upstream side A1 is restricted by the tip 110A of the cam follower 110, restricting the movement of the component 3 toward the upstream side A1. As a result, the component 3 at the pick-up position 13P is sandwiched between the front guide part 116 and the rear guide part 118 from the front to the rear, restricting the movement in the front to rear direction.

In the state shown in Figures 24A and 24B, the first restricting unit 100 restricts the movement of the component 3 at the pickup position 13P in the lateral direction B (first restricting step), and the second restricting unit 102 restricts the movement in the forward and backward directions along the conveying direction A (second restricting step). This restricts the movement of the component 3 in the horizontal direction, and the component 3 can be held in an upright position with high precision.

Then, the lead 3R of the component 3 at the pickup position 13P is cut by the lead cutting unit 107. Specifically, the movable unit 107B approaches the fixed unit 107A and sandwiches the lead 3R of the component 3 between them, thereby cutting the lead 3R.

The cutting operation of the lead 3R by the lead cutting unit 107 is performed in a state where the first restricting unit 100 and the second restricting unit 102 restrict the horizontal movement of the component 3. This prevents the component 3 from losing its posture due to the cutting operation of the lead 3R, and allows the component 3 to be accurately maintained in an upright position.

The component 3 with the leads 3R cut off is picked up by the component mounting mechanism 15 shown in FIG. 1. The component mounting mechanism 15 lowers the mounting head 22 located above the pickup position 13P, and brings the suction nozzle 22a of the mounting head 22 into contact with the upper surface of the body 3B of the component 3 to pick up the component 3. This causes the component 3 at the pickup position 13P to be picked up, and the component supply device 13 supplies the component 3.

After picking up the component 3, the component mounting mechanism 15 then inserts the leads 3R of the component 3 into the insertion holes of the board 2 to mount the component 3 on the board 2.

(Actions and Effects of Posture Correction Mechanism 42A)
As described above, the component supply device 13 of the first embodiment includes the transport path TR that transports the component 3 in the transport direction A toward the pick-up position 13P, the first drive source 34 for feeding the component 3 on the transport path TR, and the posture correction mechanism 42A that corrects the posture of the component 3 at the pick-up position 13P. The posture correction mechanism 42A includes a first regulating unit 100 that regulates the movement of the component 3 at the pick-up position 13P in the lateral direction B intersecting the transport direction A, and a second regulating unit 102 that regulates the movement in the front-rear direction along the transport direction A.

With this configuration, the posture correction mechanism 42A can be used to correct the posture of the component 3 at the pickup position 13P, thereby improving the success rate of picking up the component 3. This improves the efficiency of the component supply device 13 in supplying the component 3.

Furthermore, according to the component supply device 13 of embodiment 1, the second regulating unit 102 includes a front guide unit 116 located on the downstream side A2 of the pick-up position 13P, and a rear guide unit 118 located on the upstream side A1 of the pick-up position 13P. With this configuration, by providing the guide units 116, 118 in front of and behind the component 3 at the pick-up position 13P, movement in the front-rear direction can be regulated with high precision.

In addition, according to the component supply device 13 of embodiment 1, the second restricting unit 102 is configured to be movable along the horizontal direction B, and moves back and forth between a restricting position that restricts the movement of the component 3 at the pickup position 13P and a retreated position. With this configuration, by making the second restricting unit 102 movable, the second restricting unit 102 can perform the movement restriction operation of the component 3 in parallel with the feeding operation of the component 3.

In addition, according to the component supply device 13 of embodiment 1, the rear guide unit 118 has a rotating unit 122 configured to be rotatable in response to contact with the side of the component 3 when the rear guide unit 118 moves in a direction approaching the component 3 in front of the pick-up position 13P. With this configuration, even when the rear guide unit 118 comes into contact with the component 3 in front of the pick-up position 13P, the rotating unit 122 of the rear guide unit 118 rotates, thereby preventing interference with the component 3.

In addition, according to the component supply device 13 of embodiment 1, the second regulating unit 102 is connected to the first driving source 34 and is driven in the lateral direction B in association with the feeding operation of the component 3 by the first driving source 34. With this configuration, the feeding operation of the component 3 and the moving operation of the second regulating unit 102 can be performed using the common first driving source 34.

Furthermore, according to the component supply device 13 of embodiment 1, the posture correction mechanism 42A further has a cam mechanism 106 that converts the driving force in the front-rear direction by the first driving source 34 into a driving force in the lateral direction B and transmits it to the second restricting unit 102. With this configuration, the driving force of the first driving source 34 can be converted and transmitted to the second restricting unit 102 using a simple mechanism.

Furthermore, according to the component supply device 13 of the first embodiment, the components 3 are radial taping components, and the transport path TR transports the component holding tape 4 holding the multiple components 3 in the transport direction A. With this configuration, radial components are prone to variations in inclination in the transport direction A, particularly when the component precision is poor, but by restricting the movement in the forward and backward directions with the second restricting portion 102, it is possible to achieve a significant effect in correcting the posture.

Furthermore, according to the component supply device 13 of embodiment 1, the first regulating unit 100 includes a first horizontal guide 113 located on one side of the component 3 at the pick-up position 13P in the horizontal direction B, and a second horizontal guide 114 located on the other side. With this configuration, the movement of the component 3 in the horizontal direction B can be regulated with a simple mechanism.

The component supply device 13 of embodiment 1 further includes a lead cutting unit 107 that cuts the leads 3R of the component 3 at the pick-up position 13P. With this configuration, even when cutting the leads 3R of the component 3 at the pick-up position 13P, the cutting operation can be performed while the horizontal movement of the component 3 is restricted by the first restricting unit 100 and the second restricting unit 102, so that the posture of the component 3 can be maintained with high precision even after the leads are cut.

The component mounter 1 of the first embodiment also includes a component supply device 13 having an attitude correction mechanism 42A, and a component mounting mechanism 15. The component mounting mechanism 15 picks up a component 3 at a pickup position 13P in the component supply device 13, and inserts the leads 3R of the picked-up component 3 into the board 2 to mount the component 3 on the board 2. A component mounter 1 configured in this way can achieve the same effects as a component supply device 13 having an attitude correction mechanism 42A.

The component supply method of embodiment 1 also includes a transport step of transporting the component 3 in the transport direction A toward the pick-up position 13P, and a posture correction step of correcting the posture of the component 3 at the pick-up position 13P. In the posture correction step, a first restriction step of restricting movement of the component 3 at the pick-up position 13P in the lateral direction B intersecting the transport direction A and a second restriction step of restricting movement in the forward and backward directions along the transport direction A are executed.

By using this method, the posture of the component 3 at the pick-up position 13P can be corrected, thereby improving the success rate of picking up the component 3 and improving the efficiency of supplying the component 3.

(Modifications Related to the Posture Correcting Mechanism 42A)
In the first embodiment, as shown in FIG. 20, the pitch Y2 of the components 3 corresponds to twice the pitch Y1 of the feed holes 126 of the component holder tape 4, and when the first driving source 34 drives the components 3 two times, the components 3 are fed by one pitch. However, the present invention is not limited to this. The relationship between the pitch Y1 of the feed holes 126 and the pitch Y2 of the components 3 may be changed as appropriate, for example, when the first driving source 34 drives the components 3 one time or when the first driving source 34 drives the components 3 three times or more. Even in such a case, according to the posture correction mechanism 42A of the first embodiment, when the first driving source 34 drives the components 3 one time, the second restricting portion 102 also moves one time, so that the movement of the components 3 that arrive at the pick-up position 13P can be restricted every time. In addition, since the rotating portion 122 is provided on the rear guide portion 118, interference with the components 3 located in front of the pick-up position 13P can also be prevented.

(Embodiment 2)
A component supplying device according to a second embodiment of the present invention will be described below. In the second embodiment, differences from the first embodiment will be mainly described, and descriptions overlapping with the first embodiment will be omitted.

In the first embodiment, the first component correction mechanism 40 is a posture correction mechanism 40A (FIGS. 4 to 11D) that corrects the posture of the component 3, but in the second embodiment, the first component correction mechanism 40 is a lead pitch adjustment mechanism 40B that adjusts the pitch of the two leads 3R of the component 3. Below, the first component correction mechanism 40 is described as the lead pitch adjustment mechanism 40B.

Figures 25 and 26 are an oblique view and a plan view, respectively, of the lead pitch adjustment mechanism 40B in embodiment 2.

The lead pitch adjustment mechanism 40B includes a movable guide 200, a fixed guide 202, a stopper 204, a second drive source 206, and a cam mechanism 208. The movable guide 200, the fixed guide 202, the stopper 204, the second drive source 206, and the cam mechanism 208 are all attached to the device main body 43 that forms the transport path TR.

The movable guide 200 is a guide section configured to be movable in the lateral direction B. The movable guide 200 has the function of changing the pitch of the leads 3R by contacting the two leads 3R of the component 3 stopped at a predetermined pitch adjustment position P3 on the transport path TR. Note that in Figure 25 and subsequent figures, an example is shown in which the body 3B of the component 3 is rectangular parallelepiped shaped.

The fixed guide 202 is a guide section disposed opposite the movable guide 200 across the transport path TR, and is fixed to the device main body section 43. The fixed guide 202 is provided at a position opposite the body 3B and leads 3R of the component 3 at the pitch adjustment position P3, and has a function of maintaining the posture of the component 3 when the movable guide 200 contacts the leads 3R of the component 3.

The stopper 204, together with the fixed guide 202, is a member for maintaining the posture of the component 3 at the pitch adjustment position P3. The stopper 204 is disposed in a position facing the fixed guide 202 across the transport path TR, and is fixed to the device main body 43. When the body 3B of the component 3 is disposed between the stopper 204 and the fixed guide 202, movement of the body 3B in the lateral direction B is restricted.

The movable guide 200 and the stopper 204 are provided on the same side of the transport path TR but at different height positions. The movable guide 200 is positioned at the same height position as the leads 3R of the component 3, and the stopper 204 is positioned at the same height position as the body 3B of the component 3. The fixed guide 202 is positioned at a height position that overlaps with both the leads 3R and the body 3B of the component 3.

The second drive source 206 is a drive source for reciprocating the movable guide 200 in the lateral direction B. The second drive source 206 is provided as a drive source different from the first drive source 34 (FIG. 2) described above, and has an output shaft 207 that can be driven along the conveying direction A. The second drive source 206 in the second embodiment is a cylinder that drives the output shaft 207 back and forth. A cam mechanism 208 is connected to the output shaft 207 of the second drive source 206.

The cam mechanism 208 is a mechanism for converting the driving force of the second driving source 206 along the conveying direction A into a driving force in the lateral direction B and transmitting it to the movable guide 200. The cam mechanism 208 includes a cam 210 connected to the output shaft 207, and a cam follower 212 that engages with the cam 210 and is connected to the movable guide 200. A cam groove 211 is formed at the tip of the cam 210, and a protrusion 213 of the cam follower 212 engages with the cam groove 211. The cam groove 211 has an oblique shape in a plan view such that the cam follower 212 moves along the lateral direction B when the cam 210 moves back and forth along the conveying direction A. The cam follower 212 is attached to the device main body 43 in a state in which it can move in the lateral direction B but is restricted from moving back and forth.

With this configuration, when the second drive source 206 drives the output shaft 207 back and forth along the conveying direction A, the cam 210 moves back and forth, and the cam follower 212 engaged with the cam 210 moves back and forth in the lateral direction B. This allows the movable part 200 connected to the cam follower 212 to move back and forth in the lateral direction B. Figures 25 and 26 show an example of the state in which the movable guide 200 is closest to the fixed guide 202.

Next, the configuration of the movable guide 200, fixed guide 202, and stopper 204 will be described with reference to Figures 27 to 34.

Figures 27 and 28 are plan and perspective views, respectively, showing the movable guide 200, the fixed guide 202, the stopper 204, and the component holding tape 4. Figures 29 and 30 are plan and perspective views, respectively, showing the movable guide 200 and the component holding tape 4.

As shown in Figures 27 to 30, the movable guide 200 has two contact portions 214, 216. The contact portions 214, 216 each have the function of contacting the leads 3R (shown by dotted lines in Figure 27) of the component 3 at the pitch adjustment position P3 to adjust the pitch of the leads 3R. The contact portions 214, 216 in the second embodiment have the function of narrowing the pitch of the two leads 3R of the component 3.

As shown in Figures 29 and 30, the contact portions 214 and 216 each have a shape that protrudes in the lateral direction B toward the fixed guide 202 in the movable guide 200. The first contact portion 214 has a first inclined portion 214A and a first non-inclined portion 214B, and the second contact portion 216 has a second inclined portion 216A and a second non-inclined portion 216B.

The inclined portions 214A and 216A are both surfaces that are inclined in both the conveying direction A and the lateral direction B in a plan view. The inclined portions 214A and 216A are inclined in opposite directions in a plan view. On the other hand, the non-inclined portions 214B and 216B are surfaces that extend in the lateral direction B in a plan view.

The first inclined portion 214A contacts the rear (upstream side A1) lead 3R of the component 3 at the pitch adjustment position P3. The first inclined portion 214A in the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 202 as it approaches the downstream side A2 in the conveying direction A.

The second inclined portion 216A contacts the front (downstream side A2) lead 3R of the two leads 3R of the component 3 at the pitch adjustment position P3. The second inclined portion 216A in the first embodiment has a tapered shape that is inclined in a direction away from the fixed guide 202 as it approaches the upstream side A1 in the conveying direction A.

The first non-inclined portion 214B is a portion that extends in the lateral direction B on the inside of the first inclined portion 214A and is connected to the first inclined portion 214A. The first non-inclined portion 214B receives the lead 3R of the component 3 after it comes into contact with the first inclined portion 214A, and restricts its movement toward the upstream side A1.

The second non-inclined portion 216B is a portion that extends in the lateral direction B on the inside of the second inclined portion 216A and is connected to the second inclined portion 216A. The second non-inclined portion 216B receives the lead 3R of the component 3 after it comes into contact with the second inclined portion 216A, and restricts its movement toward the downstream side A2.

By providing the non-inclined portions 214B and 216B, the pitch of the lead 3R narrowed by the inclined portions 214A and 216A can be restricted so as not to widen.

The distance D1 between the first non-inclined portion 214B and the second non-inclined portion 216B shown in Figures 29 and 30 is set based on the desired pitch length of the lead 3R. In the first embodiment, taking into account the springback of the lead 3R, the distance D1 between the non-inclined portions 214B and 216B is set to be shorter than the desired pitch length of the lead 3R.

The movable guide 200 further has a connection portion 218. The connection portion 218 is a portion that connects the first non-inclined portion 214B and the second non-inclined portion 216B, and extends along the conveying direction A. The connection portion 218 is provided at a position recessed inward relative to the first non-inclined portion 214B and the second non-inclined portion 216B.

The position (depth) of the connection portion 218 is set at a position such that when the movable guide 200 contacts the lead 3R of the component 3, the lead 3R and the connection portion 218 face each other in the lateral direction B without contacting each other. The lead 3R of the component 3 only contacts the inclined portions 214A, 216A and the non-inclined portions 214B, 216B.

Figures 31 to 35 are perspective views showing the surrounding configuration of the movable guide 200 and the fixed guide 202.

Figure 31 shows the movable guide 200 and the fixed guide 202 separately, and Figure 32 shows the movable guide 200 approaching the fixed guide 202. Figure 33 shows the stopper 204 separately, Figure 34 shows the fixed guide 202, the stopper 204, and the component 3 held by the component holding tape 4, and Figure 35 shows the configuration shown in Figure 34 with the movable guide 200 added.

As shown in FIG. 31, the fixed guide 202 has an opposing surface 220 and two recesses 224 and 226.

The opposing surface 220 is a surface that faces the opposing surface 225 of the stopper 204 shown in FIG. 33. By sandwiching the body 3B of the part 3 between the opposing surface 220 and the opposing surface 225, the movement of the part 3 located at the pitch adjustment position P3 in the lateral direction B is restricted, as shown in FIG. 34 and FIG. 35.

The recesses 224 and 226 are recesses for receiving the contact portions 214 and 216 of the movable guide 200, respectively. As shown in FIG. 32, when the movable guide 200 approaches the fixed guide 202, the recesses 224 and 226 accommodate one end of the contact portions 214 and 216, respectively, thereby preventing interference between the movable guide 200 and the fixed guide 202.

As shown in FIG. 33, the stopper 204 has an opposing surface 225. The opposing surface 225, together with the opposing surface 220 of the fixed guide 202 described above, has the function of clamping the body 3B of the component 3, and is provided at the same height as the body 3B of the component 3.

A method for adjusting the pitch of the leads 3R of the component 3 using the lead pitch adjustment mechanism 40B having the above-mentioned configuration will be described with reference to Figures 36A to 36D. Figures 36A to 36D are plan views for explaining the method for adjusting the pitch of the leads 3R using the lead pitch adjustment mechanism 40B.

As shown in Figure 36A, the component holding tape 4 (not shown) is fed in the transport direction A (transport step), and a new component 3 stops at the pitch adjustment position P3. As the component 3 stops, the movable guide 200 is driven in the lateral direction B (arrow F1), and the contact portions 214, 216 move forward toward the two leads 3R of the component 3 at the pitch adjustment position P3. In the example shown in Figure 36A, the pitch of the two leads 3R is length D2.

When the movable guide 200 advances, as shown in FIG. 36B, the first contact portion 214 contacts the rear lead 3R of the component 3, and the second contact portion 216 contacts the front lead 3R of the component 3 (first contact step). The location of the first contact portion 214 where contact with the lead 3R of the component 3 begins is the first inclined portion 214A, and the location of the second contact portion 216 where contact with the lead 3R of the component 3 begins is the second inclined portion 216A.

Both inclined portions 214A and 216A have a tapered shape that inclines inward as it approaches connection portion 218. Therefore, as movable guide 200 advances (arrow F2), two leads 3R are pressed toward each other (arrow F3). This gradually narrows the pitch of leads 3R.

When the movable guide 200 advances further, as shown in FIG. 36C, the two leads 3R pass the inclined portions 214A, 216A and come into contact with the non-inclined portions 214B, 216B (second contact step). Since the non-inclined portions 214B, 216B have a shape that maintains a constant distance between them in the transport direction A, a pressing force is applied to the two leads 3R in a direction that narrows the pitch (arrow F4) even while the movable guide 200 advances. At this time, the pitch of the leads 3R is temporarily narrowed to the distance D1 between the non-inclined portions 214B, 216B described above.

The component 3 is also pressed in the lateral direction B by contact with the inclined portions 214A and 216A, but as shown in Figures 36B and 36C, the body 3B of the component 3 abuts against the fixed guide 202. Since a stopper 204 is also provided on the opposite side of the fixed guide 202, the component 3 at the pitch adjustment position P3 is restricted from moving in the lateral direction B, and the pitch adjustment of the leads 3R is performed.

When the movable guide 200 is retracted in the lateral direction B from the state shown in FIG. 36C (arrow F5), the movable guide 200 moves to the retracted position as shown in FIG. 36D, and the contact between the contact portions 214, 216 and the lead 3R of the component 3 is released.

Because the leads 3R of the component 3 are made of an elastic material, springback occurs in the leads 3R when they are released from contact with the contact portions 214, 216. This causes the pitch of the leads 3R to widen to a length D3 (>D1, <D2). Taking this springback into account, the distance D1 between the non-inclined portions 214B, 216B is set shorter than the desired length D3, and the pitch of the leads 3R after springback can be changed to the desired length D3.

Then, the component holding tape 4 is fed in the transport direction A, and the next component 3 stops at the pitch adjustment position P3. By moving the movable guide 200 back and forth for the next component 3 as well, the pitch of the leads 3R can be adjusted to the desired length. In this way, the pitch of the leads 3R can be adjusted for each component 3 transported along the transport path TR.

Each component 3 is transported toward the pick-up position 13P with its leads 3R at the desired pitch. This allows the component mounting mechanism 15 to pick up the component 3 and insert the leads 3R of the component 3 into the insertion holes of the board 2 with high precision, reducing the occurrence of errors caused by the pitch of the leads 3R. In this way, the efficiency with which the component supply device 13 supplies components 3 can be improved.

(Actions and Effects Related to Lead Pitch Adjustment Mechanism 40B)
As described above, the component supply device 13 of the first embodiment includes a transport path TR that transports the component 3 in the transport direction A toward the pick-up position 13P, and a lead pitch adjustment mechanism 40B that adjusts the pitch of the leads 3R of the component 3 on the transport path TR. The lead pitch adjustment mechanism 40B includes a movable guide 200 that is movable in a lateral direction B intersecting the transport direction A, and a fixed guide 202 that is provided at a position facing the movable guide 200 with the component 3 in between. The movable guide 200 has contact portions 214, 216 that can come into contact with the two leads 3R of the component 3 when the movable guide 200 moves in a direction approaching the component 3. The contact portions 214, 216 have inclined portions 214A, 216A that are inclined in a direction that narrows the pitch of the two leads 3R.

With this configuration, the pitch of the leads 3R can be adjusted by contacting the contact portions 214, 216 of the movable guide 200 with the leads 3R on the transport path TR along which the two leads 3R are transported with a gap between them in the transport direction A. This allows the pitch of the leads 3R to be adjusted on the transport path TR, improving the efficiency with which the component supply device 13 supplies components 3.

Furthermore, according to the component supply device 13 of embodiment 1, the contact portions 214, 216 further have non-inclined portions 214B, 216B extending along the lateral direction B inside the inclined portions 214A, 216A. With this configuration, the lead 3R of the component 3 comes into contact with the inclined portions 214A, 216A and then with the non-inclined portions 214B, 216B, thereby restricting the movement of the lead 3R in the transport direction A, making it easier to adjust the pitch of the lead 3R to a constant length.

Furthermore, according to the component supply device 13 of embodiment 1, the contact portions 214, 216 further have a connection portion 218 (opposing portion) on the inside of the non-inclined portions 214B, 216B, and the connection portion 218 faces the lead 3R of the component 3 that is in contact with the non-inclined portions 214B, 216B with a gap in the lateral direction B. With this configuration, by preventing the lead 3R of the component 3 from contacting the connection portion 218, it is possible to suppress damage to the lead 3R due to contact with the connection portion 218 while maintaining the contact state between the lead 3R and the non-inclined portions 214B, 216B.

Furthermore, according to the component supply device 13 of embodiment 1, the fixed guide 202 forms recesses 224, 226 that accommodate one end of the contact portions 214, 216 when the movable guide 200 approaches the fixed guide 202. With this configuration, the movable guide 200 can be moved to a position closer to the fixed guide 202, and it is possible to design the non-inclined portions 214B, 216B, for example, to be longer, thereby increasing the time and distance that the lead 3R contacts the non-inclined portions 214B, 216B.

Furthermore, according to the component supply device 13 of embodiment 1, the lead pitch adjustment mechanism 40B further includes a stopper 204 that faces the fixed guide 202 so as to sandwich the body 3B of the component 3 and is disposed at a different height position relative to the movable guide 200. With this configuration, by sandwiching the body 3B of the component 3 between the fixed guide 202 and the stopper 204 in the lateral direction B, it is possible to stabilize the posture of the component 3 when the movable guide 200 contacts the lead 3R to adjust the pitch. This improves the pitch adjustment accuracy.

Furthermore, the component supply device 13 of embodiment 1 is provided with a first drive source 34 for feeding the component 3 on the transport path TR, and a second drive source 206 for driving the movable guide 200 in the lateral direction B. With this configuration, the feeding operation of the component 3 and the movement of the movable guide 200 can be performed independently.

The component supply device 13 of the first embodiment further includes a control unit 16. The control unit 16 intermittently performs the feed operation of the component 3 by the first drive source 34, and drives the movable guide 200 by the second drive source 206 while the feed of the component 3 is stopped. With this configuration, it is possible to perform the feed operation of the component 3 and the pitch adjustment of the lead 3R while preventing interference between the movable guide 200 and the component 3.

The component mounter 1 of the first embodiment also includes a component supply device 13 having a lead pitch adjustment mechanism 40B, and a component mounting mechanism 15. The component mounting mechanism 15 picks up a component 3 at a pickup position 13P in the component supply device 13, and inserts the leads 3R of the picked-up component 3 into the board 2 to mount the component 3 on the board 2. A component mounter 1 configured in this way can achieve the same effects as a component supply device 13 having a lead pitch adjustment mechanism 40B.

The component supply method of the first embodiment also includes a transport step of transporting the component 3 in the transport direction A toward the pickup position 13P, and a lead pitch request step of adjusting the pitch of the leads 3R of the component 3. The lead pitch adjustment step uses a lead pitch adjustment mechanism 40B including a movable guide 200 that is movable in a lateral direction B intersecting the transport direction A, and a fixed guide 202 that is provided at a position facing the movable guide 200 with the component 3 in between, to move the movable guide 200 in a direction approaching the component 3, and executes a first contact step of bringing the inclined portions 214A and 216A provided on the movable guide 200 into contact with the leads 3R of the component 3 to widen the pitch of the leads 3R.

This method allows the pitch of the leads 3R to be adjusted on the transport path TR, improving the efficiency of component 3 supply.

(Modifications Related to Lead Pitch Adjustment Mechanism 40B)
In the second embodiment, the case where the lead pitch adjustment mechanism 40B narrows the pitch of the leads 3R of the component 3 has been described, but the present invention is not limited to such a case, and the pitch of the leads 3R may be adjusted to be wider. In this case, the shape of the leads 3R can be changed to one that widens the pitch by changing the inclination direction of the inclined portions 214A, 216A of the contact portions 214, 216. In this manner, it is sufficient that the inclined portions 214A, 216A of the contact portions 214, 216 are inclined in a direction that widens or narrows the pitch of the two leads 3R.

(Embodiment 3)
A component supplying device according to a third embodiment of the present invention will be described. In the third embodiment, differences from the first and second embodiments will be mainly described, and descriptions overlapping with the first and second embodiments will be omitted.

In the second embodiment, the first component correction mechanism 40 is a lead pitch adjustment mechanism 40B that adjusts the pitch of the two leads 3R of the component 3. In the third embodiment, the first component correction mechanism 40 is a "component correction mechanism 40C" that has both the function of adjusting the pitch of the leads 3R and the function of correcting the posture of the component 3. In the following, the first component correction mechanism 40 is described as the component correction mechanism 40C.

Figures 37 and 38 are an oblique view and a plan view, respectively, of the part correction mechanism 40C according to embodiment 3.

The part correction mechanism 40C includes a pusher 300, a lever member 302, a base 304, a second drive source 306, and a cam mechanism 308. The pusher 300, the lever member 302, the base 304, the second drive source 306, and the cam mechanism 308 are all attached to the device main body 43 that forms the transport path TR.

The pusher 300 is a member for pressing the lever member 302 to rotate it. The pusher 300 is configured to be movable in the lateral direction B, and moves (pressing direction G1) so as to approach the component 3 stopped at a predetermined correction position P4, passing through the gap between the two leads 3R of the component 3 and pressing the lever member 302.

The lever member 302 is a member that rotates when pressed by the pusher 300. The lever member 302 is disposed in a position facing the pusher 300 across the transport path TR. When the lever member 302 rotates, the regulating portions 336, 340 (Figure 40) of the lever member 302 face the two leads 3R of the component 3 at the correction position P4 in the transport direction A. By sandwiching the two leads 3R in the gap between the pusher 300 and the lever member 302, the leads 3R are positioned at a predetermined position, achieving the function of correcting the pitch of the leads 3R and the function of correcting the posture of the component 3.

The base 304 is a member that rotatably supports the lever member 302. The base 304 is fixed to the device main body 43.

The second drive source 306 is a drive source for reciprocating the pusher 300 in the lateral direction B. The second drive source 306 is provided as a drive source different from the first drive source 34 (FIG. 2) described above, and has an output shaft 307 that can be driven along the conveying direction A. The second drive source 306 in the third embodiment is a cylinder that drives the output shaft 307 back and forth. A cam mechanism 308 is connected to the output shaft 307 of the second drive source 306.

The cam mechanism 308 is a mechanism for converting the driving force of the second driving source 306 along the conveying direction A into a driving force in the lateral direction B and transmitting it to the pusher 300. The cam mechanism 308 includes a cam 310 connected to the output shaft 307, and a cam follower 312 that engages with the cam 310 and is connected to the pusher 300. A cam groove 311 is formed at the tip of the cam 310, and a protrusion 313 of the cam follower 312 engages with the cam groove 311. The cam groove 311 has an oblique shape in a plan view such that the cam follower 312 moves along the lateral direction B when the cam 310 moves back and forth along the conveying direction A. The cam follower 312 is attached to the device main body 43 in a state in which it can move in the lateral direction B but is restricted from moving back and forth.

With this configuration, when the second drive source 306 drives the output shaft 307 back and forth along the conveying direction A, the cam 310 moves back and forth, and the cam follower 312 engaged with the cam 310 moves back and forth in the lateral direction B. This allows the pusher 300 connected to the cam follower 312 to move back and forth in the lateral direction B. Figures 37 and 38 show an example of a state in which the pusher 300 is separated from the lever member 302 (when not in operation).

Next, the peripheral configuration of the pusher 300 and the lever member 302 will be described with reference to Figures 39 to 42. In Figures 39 to 42, part 3 is not shown.

Figure 39 is an enlarged perspective view of the pusher 300 and the lever member 302.

As shown in FIG. 39, the pusher 300 has a pressing surface 314 for pressing the lever member 302. The pressing surface 314 is one end of the pusher 300 that protrudes in the lateral direction B, and faces the lever member 302 in the lateral direction B. The pressing surface 314 is a surface that extends along the conveying direction A in a plan view.

The lever member 302 has a first lever 316 and a second lever 318.

The first lever 316 and the second lever 318 are each configured to be rotatable, and rotate when pressed by the pressing surface 314 of the pusher 300. In the third embodiment, the first lever 316 and the second lever 318 are pressed in the pressing direction G1 by the pressing surface 314 of the same pusher 300.

The first lever 316 can rotate in a rotation direction R4 around a first rotation shaft 317 extending in the Z-axis direction, and the second lever 318 can rotate in a rotation direction R5 around a second rotation shaft 319 extending in the Z-axis direction. When the first lever 316 rotates, it faces the rearward (upstream side A1) lead 3R of the two leads 3R of the part 3. When the second lever 318 rotates, it faces the forward (downstream side A2) lead 3R of the two leads 3R of the part 3.

The part correction mechanism 40C further includes a biasing member 320, a first stopper 322, and a second stopper 324.

The biasing member 320 is a member for biasing the first lever 316 and the second lever 318. The biasing member 320 of the third embodiment is a spring-like member that connects the first lever 316 and the second lever 318, and biases the first lever 316 and the second lever 318 in a pulling direction.

The first lever 316 is biased by the biasing member 320 in a rotational direction R6 opposite the rotational direction toward the lead 3R on the rear side of the component 3. The second lever 318 is biased by the biasing member 320 in a rotational direction R7 opposite the rotational direction toward the lead 3R on the front side of the component 3. By providing the biasing member 320, the first lever 316 and the second lever 318 can be retracted when not pressed by the pusher 300 (when not operating).

The first stopper 322 is a member that restricts further rotation of the first lever 316 that is biased by the biasing member 320. The second stopper 324 is a member that restricts further rotation of the second lever 318 that is biased by the biasing member 320. By providing the first stopper 322 and the second stopper 324, the first lever 316 and the second lever 318 are each stopped at a predetermined retracted position.

The first stopper 322 and the second stopper 324 have the function of restricting the rotation of the levers 316 and 318, as well as the function of helping to prevent the lead 3R of the component 3 from falling off when the levers 316 and 318 rotate due to the pressure of the pusher 300. Details will be described later.

Next, the detailed configuration of the pusher 300, lever member 302, biasing member 320, and stoppers 322, 324 will be described with reference to Figures 40 to 42. Figures 40 to 42 are perspective views of the pusher 300, lever member 302, biasing member 320, and stoppers 322, 324.

As shown in Figures 40 to 42, in addition to the pressing surface 314, the pusher 300 has a first inclined surface 326, a second inclined surface 328, a first opposing surface 330, a second opposing surface 331, a third opposing surface 332, and a fourth opposing surface 333.

The first inclined surface 326 and the second inclined surface 328 are surfaces that are inclined with respect to the conveying direction A and the lateral direction B, respectively, in a plan view. The first inclined surface 326 is located opposite the first lever 316 in the lateral direction B, and the second inclined surface 328 is located opposite the second lever 318 in the lateral direction B.

The first inclined surface 326 and the second inclined surface 328 are inclined in different directions. The first inclined surface 326 is inclined in a direction away from the lever member 302 as it moves toward the upstream side A1 of the conveying direction A, and the second inclined surface 328 is inclined in a direction away from the lever member 302 as it moves toward the downstream side A2 of the conveying direction A.

The first opposing surface 330 and the second opposing surface 331 are surfaces that are located on the inside of the first inclined surface 326 and the second inclined surface 328, respectively, and extend along the lateral direction B in a plan view. The first opposing surface 330 and the second opposing surface 331 are surfaces that face the lead 3R of the component 3 from the side opposite the levers 316 and 318 when the levers 316 and 318 rotate. The first opposing surface 330 faces the lead 3R on the rear side of the component 3 together with the first lever 316, and the second opposing surface 331 faces the lead 3R on the front side of the component 3 together with the second lever 318.

By providing the opposing surfaces 330 and 331, the lead 3R of the component 3 can be clamped together with the lever member 302 in the transport direction A and positioned at a predetermined position. This allows the pitch of the two leads 3R to be adjusted and the position of the component 3 in the transport direction A to be corrected.

The third opposing surface 332 and the fourth opposing surface 333 are surfaces that are respectively located inside the first opposing surface 330 and the second opposing surface 331, and extend along the conveying direction A in a plan view. The third opposing surface 332 and the fourth opposing surface 333 are respectively surfaces that face the leads 3R of the component 3 in the lateral direction B when the pusher 300 advances in the pressing direction G1. The third opposing surface 332 faces the leads 3R on the rear side of the component 3, and the fourth opposing surface 333 faces the leads 3R on the front side of the component 3.

As shown in Figures 40 to 42, the first lever 316 has a first pressed portion 334 and a first restricting portion 336.

The first pressed portion 334 is an end portion pressed by the pressing surface 314 of the pusher 300, and faces the pressing surface 314 in the lateral direction B. The first restricting portion 336 is an end portion at a different position from the first pressed portion 334, and faces the lead 3R on the rear side of the component 3 when the first lever 316 rotates.

As shown in Figures 40 to 42, the second lever 318 has a second pressed portion 338 and a second restricting portion 340.

The second pressed portion 338 is an end portion pressed by the pressing surface 314 of the pusher 300, and faces the pressing surface 314 in the lateral direction B. The second restricting portion 340 is an end portion at a different position from the second pressed portion 338, and contacts the lead 3R on the front side of the component 3 when the second lever 318 rotates.

As shown in FIG. 40, the first stopper 322 has a first lever abutment portion 342 and a first lead facing portion 344.

The first lever contact portion 342 is a portion that contacts the first lever 316 biased by the biasing member 320 to prevent further rotation in the rotation direction R6. The first lead facing portion 344 is a portion that faces the third facing surface 332 of the pusher 300, sandwiching the rear lead 3R of the component 3, when the pusher 300 advances in the pressing direction G1.

As shown in FIG. 40, the second stopper 324 has a second lever abutment portion 346 and a second lead facing portion 348.

The second lever contact portion 346 is a portion that contacts the second lever 318 biased by the biasing member 320 to prevent further rotation in the rotation direction R7. The second lead facing portion 348 is a portion that faces the fourth facing surface 333 of the pusher 300, sandwiching the lead 3R on the front side of the component 3, when the pusher 300 advances in the pressing direction G1.

A method for adjusting the pitch of the leads 3R of the component 3 and correcting the posture of the component 3 using the component correction mechanism 40C having the above-mentioned configuration will be described with reference to Figures 43A and 43B. Figures 43A and 43B are schematic plan views for explaining the method for correcting the component 3 using the component correction mechanism 40C.

As shown in FIG. 43A, when the pusher 300 is in the retracted position (not in operation), the component holding tape 4 is pitch-fed in the transport direction A (transport step), and one component 3 (shown by the dotted line) stops at the correction position P4. As the component 3 stops, the second drive source 306 (FIGS. 37 and 38) drives the pusher 300 to advance in the pressing direction G1.

When the pusher 300 advances in the pressing direction G1, the pressing surface 314 of the pusher 300 passes between the two leads 3R and moves toward the pressed portions 334 and 338 of the levers 316 and 318.

As shown in FIG. 43B, the pressing surface 314 of the pusher 300 contacts the pressed portions 334, 338 of the levers 316, 318 and presses them in the pressing direction G1. Each of the levers 316, 318 rotates, with the first lever 316 rotating in the rotation direction R8 around the first rotation shaft 317, and the second lever 318 rotating in the rotation direction R9 around the second rotation shaft 319 (part correction step).

As the first lever 316 rotates, the first restricting portion 336 faces the lead 3R on the rear side (upstream side A1) of the component 3 in the first pressing direction H1. The first pressing direction H1 is a direction toward the downstream side A2 of the transport direction A. In the example shown in FIG. 43B, the first restricting portion 336 contacts the lead 3R of the component 3 and presses it in the first pressing direction H1. The lead 3R of the component 3 pressed in the first pressing direction H1 is pressed toward the first opposing surface 330 of the advanced pusher 300. As a result, the rear lead 3R is positioned in the gap between the first restricting portion 336 and the first opposing surface 330, and movement in the front-rear direction along the transport direction A is restricted (first lead correction step).

The lead 3R is further sandwiched between the third opposing surface 332 of the advanced pusher 300 and the first lead opposing portion 344 of the first pusher 322. This also restricts the movement of the rear lead 3R in the lateral direction B. In this way, the horizontal movement of the lead 3R is restricted.

The first restricting portion 336 of the first lever 316, which rotates in the rotation direction R8, comes into contact with the first lead facing portion 344 of the first stopper 322, restricting further rotation. The first lead facing portion 344 also functions as a stopper for the first lever 316.

As the second lever 318 rotates, the second restricting portion 340 faces the lead 3R on the front side (downstream side A2) of the component 3 in the second pressing direction H2. The second pressing direction H2 is a direction toward the upstream side A1 of the transport direction A. In the example shown in FIG. 43B, the second restricting portion 340 contacts the lead 3R of the component 3 and presses it in the second pressing direction H2. The lead 3R of the component 3 pressed in the second pressing direction H2 is pressed toward the second opposing surface 331 of the advanced pusher 300. As a result, the lead 3R on the front side is positioned in the gap between the second restricting portion 340 and the second opposing surface 331, and movement in the front-rear direction along the transport direction A is restricted (second lead correction step).

The lead 3R is further sandwiched between the fourth opposing surface 333 of the advanced pusher 300 and the second lead opposing portion 348 of the second pusher 324. This also restricts the movement of the front lead 3R in the lateral direction B. In this way, the horizontal movement of the lead 3R is restricted.

The second restricting portion 340 of the second lever 318, which rotates in the rotation direction R9, comes into contact with the second lead facing portion 348 of the second stopper 324, restricting further rotation. The second lead facing portion 348 also functions as a stopper for the second lever 318.

In the state shown in Figure 43B, the two leads 3R are each positioned at a predetermined position, so that the pitch of the leads 3R is adjusted to a desired length and the posture of the component 3 is corrected. If the pitch of the two leads 3R is wider than the desired pitch length in the pre-adjustment state shown in Figure 43A, the restricting portions 336, 340 press the two leads 3R in a direction toward each other, as shown in Figure 43B, thereby narrowing the pitch of the leads 3R. At the same time, if the two leads 3R are each inclined relative to the vertical direction (Z-axis direction), the component 3 is corrected to an upright posture.

Then, when the pusher 300 is driven in the retraction direction G2 opposite to the pressing direction G1, the state returns to the same state as that shown in FIG. 43A. Although springback occurs in the lead 3R, the pitch of the lead 3R approaches the desired pitch length and the posture of the part 3 approaches an upright posture compared to the state before the pusher 300 is operated.

Then, the component holding tape 4 is fed in the transport direction A, and the next component 3 is stopped at the correction position P4. By moving the pusher 300 back and forth for the next component 3 as well, the pitch of the leads 3R can be adjusted to the desired length and the tilt of the component 3 can be corrected. In this way, the pitch of the leads 3R can be adjusted and the tilt of the component 3 can be corrected for each component 3 transported along the transport path TR.

Each component 3 is transported toward the pick-up position 13P with its leads 3R at the desired pitch. This allows the component mounting mechanism 15 to pick up the component 3 and insert the leads 3R of the component 3 into the insertion holes in the board 2 with high precision, reducing the occurrence of errors caused by the pitch of the leads 3R. Furthermore, each component 3 is transported toward the pick-up position 13P while maintained in a generally upright position, improving the success rate of picking up the component 3 by the component mounter 15. In this way, the efficiency of supplying components 3 by the component supply device 13 can be improved.

In the example shown in Figures 43A and 43B, the pitch of the two reeds 3R before the pusher 300 operates is wide, and the pitch of the reeds 3R is narrowed. However, this is not the only case, and the pitch of the reeds 3R can be adjusted to be wider. For example, in the state before adjustment shown in Figure 43A, if the pitch of the two reeds 3R is narrow, the two reeds 3R contact the inclined surfaces 326 and 328 as the pusher 300 advances. The rear reed 3R contacts the first inclined surface 326, and the front reed 3R contacts the second inclined surface 328. Depending on the inclination direction of each of the inclined surfaces 326 and 328, the rear reed 3R is guided outward (upstream side A1) toward the first opposing surface 330, and the front reed 3R is guided outward (downstream side A2) toward the second opposing surface 331. This widens the pitch between the two leads 3R, and positions the leads 3R at a predetermined position, as in the case shown in Figure 43B. In this way, even if the pitch of the leads 3R is narrow, the use of the inclined surfaces 326 and 328 makes it possible to widen the pitch of the leads 3R and correct the posture of the component 3.

(Actions and Effects Related to Part Correcting Mechanism 40C)
As described above, the component supply device 13 of the third embodiment includes a transport path TR that transports the component 3 in the transport direction A toward the pick-up position 13P, and a component correction mechanism 40C for correcting the component 3 on the transport path TR. The component correction mechanism 40C includes a pusher 300 that is movable in a lateral direction B intersecting the transport direction A so as to pass between the leads 3R, and a lever member 302 that rotates when pressed by the pusher 300. The lever member 302 includes a first lever 316 and a second lever 318. The first lever 316 rotates about a first rotation axis 317 in response to the pressure of a pressing surface 314 (first pressing surface) of the pusher 300, and sandwiches the lead 3R (first lead) of the component 3 between the first opposing surface 330 of the pusher 300. The second lever 318 rotates about a second rotation axis 319 in response to pressure from the pressing surface 314 (second pressing surface) of the pusher 300 , and clamps the lead 3 R (second lead) of the component 3 between itself and a second opposing surface 331 of the pusher 300 .

With this configuration, the two leads 3R are clamped between the pusher 300 and the two levers 316, 318, making it possible to adjust the pitch of the two leads 3R and correct the inclination of the component 3. This improves the efficiency with which the component supply device 13 supplies the component 3.

Furthermore, according to the component supply device 13 of embodiment 3, the first lever 316 has a first regulating portion 336 that clamps the lead 3R (first lead) between the first opposing surface 330 of the pusher 300 to regulate movement in the conveying direction A, and the second lever 318 has a second regulating portion 340 that clamps the lead 3R (second lead) between the second opposing surface 331 of the pusher 300 to regulate movement in the conveying direction A. With this configuration, by regulating the movement of the two leads 3R in the conveying direction A, it is possible to accurately adjust the pitch of the leads 3R and correct the inclination of the component 3.

Furthermore, according to the component supply device 13 of embodiment 3, the pusher 300 further has a third opposing surface 332 that faces in the lateral direction B the lead 3R (first lead) that is sandwiched between the first opposing surface 330 and the first lever 316, and a fourth opposing surface 333 that faces in the lateral direction B the lead 3R (second lead) that is sandwiched between the second opposing surface 331 and the second lever 318. With this configuration, the opposing surfaces 332 and 333 can prevent the lead 3R from falling off in the lateral direction B.

Furthermore, according to the component supply device 13 of embodiment 3, the pusher 300 further has a first inclined surface 326 that extends at an angle between the pressing surface 314 (first pressing surface) and the first opposing surface 330, and a second inclined surface 328 that extends at an angle between the pressing surface 314 (second pressing surface) and the second opposing surface 331. With this configuration, the leads 3R of the component 3 can be brought into contact with the inclined surfaces 326, 328 and guided toward the opposing surfaces 330, 331, particularly when the pitch of the leads 3R is narrow.

Furthermore, according to the component supply device 13 of embodiment 3, the first lever 316 is disposed upstream of the second lever 318 in the conveying direction A, the first inclined surface 326 has a shape inclined in a direction away from the first lever 316 toward the upstream side A1 of the conveying direction A, and the second inclined surface 328 has a shape inclined in a direction away from the second lever 318 toward the downstream side A2 of the conveying direction A. With this configuration, it is possible to miniaturize the tip of the pusher 300.

In addition, according to the component supply device 13 of embodiment 3, the pressing surface 314 (first pressing surface) that presses the first lever 316 and the pressing surface 314 (second pressing surface) that presses the second lever 318 are formed on the same surface of the pusher 300. With this configuration, the configuration of the pusher 300 can be simplified.

Furthermore, according to the component supply device 13 of embodiment 3, the component correction mechanism 40C further includes a biasing member 320 that biases the first lever 316 in a rotational direction R6 away from the rear lead 3R (first lead) of the component 3, and biases the second lever 318 in a rotational direction R7 away from the front lead 3R (second lead) of the component 3. With this configuration, the lever member 302 can be retracted when it is not pressed by the pusher 300.

According to the component supply device 13 of the third embodiment, the component correction mechanism 40C further includes a first stopper 322 that contacts the first lever 316 biased by the biasing member 320 (first biasing member) to restrict further rotation of the first lever 316, and a second stopper 324 that contacts the second lever 318 biased by the biasing member (second biasing member) to restrict further movement of the second lever 318. With this configuration, the levers 316 and 318 biased by the biasing member 320 can be kept waiting at a predetermined retreat position away from the transport path TR.

Furthermore, according to the component supply device 13 of embodiment 3, the first stopper 322 is arranged at a position facing the lead 3R (first lead) sandwiched between the first opposing surface 330 of the pusher 300 and the first lever 316 in the horizontal direction B, and the second stopper 324 is arranged at a position facing the lead 3R (second lead) sandwiched between the second opposing surface 331 of the pusher 300 and the second lever 318 in the horizontal direction B. With this configuration, the stoppers 322 and 324 can prevent the lead 3R from falling off in the horizontal direction B.

In addition, according to the component supply device 13 of embodiment 3, the first lever 316 and the second lever 318 are biased by a common biasing member 320. With this configuration, the number of components in the component correction mechanism 40C can be reduced, leading to cost reduction.

The component mounter 1 of the third embodiment also includes a component supply device 13 having a component correction mechanism 40C, and a component mounting mechanism 15. The component mounting mechanism 15 picks up a component 3 at a pickup position 13P in the component supply device 13, and inserts the leads 3R of the picked-up component 3 into the board 2 to mount the component 3 on the board 2. A component mounter 1 configured in this way can achieve the same effects as a component supply device 13 having a component correction mechanism 40C.

The component supply method of the third embodiment also includes a conveying step of conveying the component 3 in the conveying direction A toward the pickup position 13P, and a component correction step of correcting the component 3. The component correction step includes a first lead correction step and a second lead correction step, which are performed using the component correction mechanism 40C. In the first lead correction step, the first lever 316 of the lever member 302 is pressed and rotated by the pressing surface 314 (first pressing surface) of the pusher 300, and the lead 3R (first lead) of the component 3 is sandwiched between the first opposing surface 330 and the first lever 316 of the pusher 300. In the second lead correction step, the second lever 318 of the lever member 302 is pressed and rotated by the pressing surface 314 (second pressing surface) of the pusher 300, and the lead 3R (second lead) of the component 3 is sandwiched between the second opposing surface 331 and the second lever 318 of the pusher 300.

According to this component supply method, by clamping the two leads 3R between the pusher 300 and the two levers 316, 318, it is possible to adjust the pitch of the leads 3R and correct the inclination of the components 3. This makes it possible to improve the efficiency of supplying the components 3.

(Modifications Related to Component Correcting Mechanism 40C)
In the third embodiment, the case where one pusher 300 presses two levers 316, 318 has been described, but the present invention is not limited to this case, and the two levers may be pressed by separate pushers. This modified example will be described with reference to Figs. 44 to 45B.

Figure 44 is a perspective view showing a part correction mechanism 40D according to a modified example of embodiment 3. Figures 45A and 45B are schematic plan views for explaining a method of correcting part 3 using part correction mechanism 40D according to this modified example.

The part correction mechanism 40D shown in FIG. 44 has two pushers 400A and 400B and two levers 416 and 418.

The first pusher 400A is a member that presses the first lever 416 to rotate it, and the second pusher 400B is a member that presses the second lever 418 to rotate it. The first pusher 400A, together with the first lever 416, positions the rear lead 3R (not shown) of the component 3 at the first correction position P5. The second pusher 400B, together with the second lever 418, positions the rear lead 3R (not shown) of the component 3 at the second correction position P6.

In this modified example, the two pushers 400A and 400B are integrally formed and driven in the lateral direction B by the same drive source (e.g., the second drive source 306 in embodiment 3).

The first pusher 400A has a first pressing surface 414A, a first inclined surface 426, a first opposing surface 430, and a third opposing surface 432. Hereinafter, members with the same names as those in the third embodiment have the same configurations and functions as those described in the third embodiment, and detailed descriptions thereof will be omitted.

The first lever 416 is rotatable around the first rotation shaft 417, and has a first pressed portion 434 and a first restricting portion 436. The first biasing member 420A biases the first lever 416 in the rotation direction R10. The first support portion 421A is an axial member that supports one end of the spring-shaped first biasing member 420A, and is attached to the base 404 together with the first rotation shaft 417. The first stopper 422 restricts further rotation of the first lever 416 biased by the first biasing member 420A in the rotation direction R10.

The second pusher 400B has a second pressing surface 414B, a second inclined surface 428, a second opposing surface 431, and a fourth opposing surface 433.

The second lever 418 is rotatable around the second rotation shaft 419, and has a second pressed portion 438 and a second restricting portion 440. The second biasing member 420B biases the second lever 418 in the rotation direction R11. The second support portion 421B is an axial member that supports one end of the spring-shaped second biasing member 420B, and is attached to the base 404 together with the second rotation shaft 419. The second stopper 424 restricts further rotation of the second lever 418 biased by the second biasing member 420B in the rotation direction R11.

As shown in FIG. 45A, when the pushers 400A and 400B are in the retracted position (non-operating), the component holder tape 4 is transported in the transport direction A, and one component 3 stops at the first correction position P5, and the adjacent component 3 stops at the second correction position P6. As the components 3 stop, the pushers 400A and 400B are driven in the pressing direction G3.

When the pushers 400A and 400B move in the pressing direction G3, the first pressing surface 414A of the first pusher 400A passes between the two leads 3R of the part 3 at the first correction position P5 and advances toward the first pressed portion 434 of the first lever 416. Similarly, the second pressing surface 414B of the second pusher 400B passes between the two leads 3R of the part 3 at the second correction position P6 and advances toward the second pressed portion 438 of the second lever 418.

As shown in FIG. 45B, the first pressing surface 414A of the first pusher 400A presses the first lever 416, causing the first lever 416A to rotate in the rotation direction R12. The first restricting portion 436 of the first lever 416 positions the rear lead 3R of the component 3 by sandwiching it between the first opposing surface 430 (FIG. 45A) of the advanced first pusher 400A. The lead 3R is also sandwiched between the third opposing surface 432 of the first pusher 400A and the first pusher 422, restricting horizontal movement.

Similarly, the second pressing surface 414B of the second pusher 400B presses the second lever 418, causing the second lever 418 to rotate in the rotation direction R13. The second restricting portion 440 of the second lever 418 positions the lead 3R on the front side of the component 3 by sandwiching it between the second opposing surface 431 (FIG. 45A) of the advanced second pusher 400B. The lead 3R is also sandwiched between the fourth opposing surface 433 of the second pusher 400B and the second pusher 424, restricting horizontal movement.

According to the above operation, the rear lead 3R of the component 3 at the first correction position P5 is positioned at a predetermined position, and the front lead 3R of the component 3 at the second correction position P6 is positioned at a predetermined position. This makes it possible to correct the posture of the component 3 at each of the correction positions P5 and P6, and to adjust the final pitch of the two leads 3R to a desired length. Furthermore, by stopping the component 3 at the first correction position P5 and the second correction position P6 in turn, the posture of the component 3 can be corrected to an upright posture while taking springback into consideration, regardless of whether the component 3 is tilted forward or backward.

Although the present invention has been described above with reference to the above-mentioned embodiments 1 to 3, the present invention is not limited to the above-mentioned embodiments 1 to 3. For example, both the posture correction mechanism 40A of embodiment 1 and the lead pitch adjustment mechanism 40B of embodiment 2 may be provided in the same component supply device 13. This makes it possible to adjust the pitch of the leads 3R while correcting the posture of the component 3 midway along the transport path TR.

Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various modifications and variations will be apparent to those skilled in the art. Such modifications and variations are to be understood as being included within the scope of the present disclosure as defined by the appended claims, unless they deviate therefrom. In addition, changes in the combination and order of elements in each embodiment may be made without departing from the scope and spirit of the present disclosure.

In addition, among the above-mentioned embodiments and various modifications, any of the embodiments and modifications can be appropriately combined to achieve the effects of each.

The present invention can be applied to any component supply device that supplies radial components and other components, a component mounting machine equipped with the same, and a component supply method.
