Description

The present invention relates to an anvil unit and a component mounting device equipped with the same.

Conventionally, components such as radial and axial components have two leads, which are inserted into insertion holes provided in a substrate. A component mounting device that inserts such leaded components into a substrate and mounts them includes an anvil unit. The anvil unit has a lead processing section for processing the leads that protrude from and extend to the underside of the substrate (see, for example, Patent Document 1). The lead processing section processes the leads by bending them, etc.

The anvil unit in Patent Document 1 includes multiple guide pins that guide the leads into the insertion holes in the substrate, and multiple selection rods that selectively move each guide pin up and down. Each guide pin is inserted into the insertion hole in the substrate from below and engages with a lead above the substrate. Each selection rod is connected to the lower end of the guide pin and is driven by a cylinder or the like to move each guide pin up and down as a unit.

Each guide pin moves up and down between a retracted position below the board and a protruding position protruding upward through an insertion hole in the board. When three or more selection rods are provided, two selection rods that move up and down are selected according to the pitch of the two leads guided by the guide pins.

JP 2007-109849 A

Nowadays, components are inserted into a circuit board in a variety of orientations, and the anvil unit can rotate according to the orientation of the component. If the anvil unit is configured so that the guide pin and the upper end of the selection rod rotate together, while the lower end of the selection rod is fixed in position and does not rotate, depending on the rotational position of the anvil unit, the selection rods may interfere with each other and be unable to rotate any further. It can be said that there is still room for improvement in the rotational flexibility of the anvil unit.

The object of the present invention is therefore to provide an anvil unit with improved rotational flexibility and a component mounting device equipped with the same, in order to solve the above problems.

In order to achieve the above object, the anvil unit of the present invention includes an anvil body having a lead processing section for processing the leads of a component inserted into an insertion hole of a substrate and having a rotation function, at least two guide pins that are inserted into the insertion hole of the substrate and guide the leads of the component toward the insertion hole, at least two selection rods provided corresponding to each of the at least two guide pins and each having a first end and a second end that are coupled to the guide pin, and a small amount of pressure that is provided corresponding to each of the at least two selection rods and is coupled to the second end of the selection rod to move the selection rod up and down. The anvil body includes at least two selection rod drive units, and a connection unit that connects the at least two guide pins and the first ends of the at least two selection rods to the anvil body so that they rotate with the rotation of the anvil body. The second ends of the at least two selection rods are fixed in position by the selection rod drive units, and the positions of the second ends of the at least two selection rods are set so that lines connecting the first ends and the second ends of each selection rod do not intersect at any height while the rotational positions of the first ends of the at least two selection rods are within a predetermined range.

The component mounting device of the present invention also includes a board positioning section that positions a board at a predetermined mounting position, a mounting head that picks up a component and inserts the leads of the component into the board positioned at the mounting position, and an anvil unit having a lead processing section that processes the leads of the component.

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)
First, a component mounting device according to an embodiment of the present invention will be described with reference to Fig. 1. The component mounting device 1 of the first embodiment is a device that inserts and mounts a component 3 on a substrate 2. Hereinafter, directions horizontal to the substrate 2 are defined as the X direction and the Y direction, and a direction perpendicular to the XY plane, i.e., the up-down direction (vertical direction), is defined as the Z direction.

As shown in FIG. 1, the component mounting device 1 includes a plurality of feeders 4, a substrate positioning unit 6, a control unit 8, a pallet 9, a mounting head 10, a transfer chuck 11, an anvil unit 12, a first drive mechanism 14, and a second drive mechanism 16. In FIG. 1, each component of the component mounting device 1 is illustrated in a schematic manner.

The feeder 4 is a component supplying section that stores components 3 with leads. As shown in FIG. 1, multiple feeders 4 are provided and are arranged along the X direction. Each feeder 4 stores multiple components 3. The components may also be referred to as "components with leads." The components 3 may be any electronic components that have leads, such as radial components or axial components. In the first embodiment, the components 3 are radial components.

The board positioning unit 6 is a member for positioning the board 2. The board positioning unit 6 in the first embodiment is a rail-shaped member that transports the board 2 in the X and Y directions as shown by the arrows X1 and Y1 in FIG. 1, and positions it at a predetermined mounting position. FIG. 1 shows the state in which the board 2 is positioned at the mounting position. The driving mechanism that drives the board positioning unit 6 will not be described or illustrated.

The control unit 8 is a component that controls the operation of each component of the component mounting device 1. The control unit 8 is electrically connected to each component of the component mounting device 1 via wiring or the like. The control unit 8 is composed of, for example, a microcomputer.

The pallet 9 is a member that arranges the components 3 in sequence between the feeder 4 and the mounting head 10. Multiple pallets 9 are provided, and are attached in sequence to an endless pallet belt 9A. Each component 3 supplied from the feeder 4 is held on each pallet 9 (the components 3 are not shown in Figure 1). The components 3 held on the pallet 9 are removed by a transfer chuck 11, which will be described later, and transferred to the mounting head 10.

The mounting head 10 is a head for inserting the leads of the component 3 into the insertion holes 17 of the board 2 that has been positioned by the board positioning unit 6. The mounting head 10 is positioned above the board positioning unit 6, and inserts the leads of the component 3 from above into the insertion holes 17 of the board 2. The mounting head 10 includes a body chuck 10A, a guide chuck 10B, and a pusher 10C.

The body chuck 10A is a member that receives and holds the part 3 from the transfer chuck 11. The body chuck 10A has a pair of claws that clamp and hold the body of the part 3 that is handed over from the transfer chuck 11. The body chuck 10A is controlled to descend while holding the body of the part 3.

The guide chuck 10B is a member that guides the engagement between the lead of the component 3 held by the body chuck 10A and the upper end of a guide pin 26 (described later). The guide chuck 10B has a pair of claws, and guides the engagement between the lead of the component 3 and the guide pin 26 by inserting them into the space between the pair of claws.

The pusher 10C is a member for pushing down the component 3 while it is engaged with the guide pin 26. By pushing down the component 3, the pusher 10C can guide the leads of the component 3 into the insertion hole 17 of the board 2.

The up and down movement (arrow Z1) and rotational movement (XY1) of each component of the mounting head 10 described above are performed by the first drive mechanism 14.

The transfer chuck 11 is a member for removing the part 3 held on the pallet 9 and transferring it to the body chuck 10A. The transfer chuck 11 has a pair of claws, which clamp and hold the leads of the part 3 held on the pallet 9. The transfer chuck 11 moves closer to the body chuck 10A while holding the leads of the part 3, and the body chuck 10A clamps the body of the part 3. This transfers the part 3 from the transfer chuck 11 to the body chuck 10A.

The anvil unit 12 is a unit for processing the leads of the component 3 inserted into the insertion hole 17 of the board 2 and attaching the component 3 to the board 2. The anvil unit 12 is positioned below the board positioning unit 6 and processes the leads of the component 3 from below. The anvil unit 12 is driven by the second drive mechanism 16.

The second drive mechanism 16 has the function of linearly moving the anvil unit 12 in the Z direction and the function of rotationally moving the anvil unit 12 within the XY plane, as shown by the arrows Z2 and XY2 in FIG. 1.

The anvil unit 12 comprises a lead processing section 18, an anvil body section 20, a hose 22, and an insertion guide mechanism 24.

The lead processing section 18 is a member for processing the leads of the component 3. The lead processing section 18 of the first embodiment has a cutting blade that clinches and cuts the leads of the component 3. The lead processing section 18 is erected on the anvil body section 20.

The anvil body 20 is a member that constitutes the main body of the anvil unit 12, and the lead processing section 18 is erected on its upper surface. In addition to the lead processing section 18, a hose 22 and an insertion guide mechanism 24 are connected to the anvil body 20.

The hose 22 is a hose connected to the anvil body 20. The hose 22 in the first embodiment is a hose for disposing of lead waste generated by cutting the lead processing portion 18, and is connected to a vacuum source (not shown).

The insertion guide mechanism 24 is a mechanism for guiding the insertion of the leads of the component 3 into the insertion holes 17 of the board 2. The insertion guide mechanism 24 has multiple guide pins 26 for guiding the insertion of the leads. The multiple guide pins 26 protrude upward and are inserted into the inside of the anvil body 20, allowing them to move up and down.

The lead guide function of the guide pin 26 is explained using Figure 2.

Figure 2 is a schematic diagram for explaining the lead guide function of the guide pin 26. In Figure 2, the insertion guide mechanism 24 and some components of the mounting head 10 are not shown.

As shown in FIG. 2, each guide pin 26 is configured to be movable up and down between a retracted position below the board 2 and an engagement position where it is inserted into the insertion hole 17 of the board 2 and engages with the lead of the component 3. The tip of the guide pin 26 is formed in a cylindrical shape, and can engage with the lead of the component 3 to accommodate the lead.

First, the body chuck 10A (not shown) descends while holding the body of the component 3, and inserts the leads of the component 3 between a pair of jaws of the guide chuck 10B (not shown). Furthermore, the two guide pins 26 that have risen to the engagement position through the insertion hole 17 of the board 2 are also inserted between the pair of jaws of the guide chuck 10B. As a result, the leads of the component 3 are accommodated in the upper ends of the guide pins 26 as shown in FIG. 2. In this state, the body chuck 10A and the guide chuck 10B retract, and the component 3 is pushed down by the pusher 10C (not shown) as shown by the arrow Z3, and the two guide pins 26 also descend in sync. In this way, the leads of the component 3 accommodated in the tips of the guide pins 26 can be guided into the insertion holes 17.

In the first embodiment, five guide pins 26 are provided. Two selection rods 28 that move up and down are selected according to the pitch of the leads of the component 3 that are guided by the guide pins 26.

Using the component mounting device 1 having the above-described configuration, a component mounting board is manufactured in which multiple components 3 are mounted on a board 2.

The detailed configuration of the insertion guide mechanism 24 is explained below with reference to Figure 3 onwards.

Figure 3 is a schematic diagram showing the peripheral configuration of the insertion guide mechanism 24. As shown in Figure 3, the insertion guide mechanism 24 includes a plurality of guide pins 26, a plurality of selection rods 28, a plurality of selection rod drive units 30, and a connecting unit 32.

The selection rod 28 is a member that is connected to the lower end of the guide pin 26 and moves up and down together with the guide pin 26. A selection rod 28 is provided corresponding to each of the guide pins 26, and five selection rods 28 are provided in the first embodiment.

The plurality of selection rods 28 includes a first selection rod 40, a second selection rod 42, a third selection rod 44, a fourth selection rod 46, and a fifth selection rod 48.

Each of the selection rods 40, 42, 44, 46, and 48 has a first end coupled to the guide pin 26 and a second end coupled to the selection rod drive unit 30. Specifically, the first selection rod 40 has a first end 40A and a second end 40B, the second selection rod 42 has a first end 42A and a second end 42B, the third selection rod 44 has a first end 44A and a second end 44B, the fourth selection rod 46 has a first end 46A and a second end 46B, and the fifth selection rod 48 has a first end 48A and a second end 48B.

The selection rod drive unit 30 is a drive unit that moves each selection rod 28 up and down, and moves the selection rod 28 and the guide pin 26 up and down together as shown by the arrow Z4. A selection rod drive unit 30 is provided corresponding to each of the selection rods 28, and five selection rod drive units 30 are provided in the first embodiment.

The multiple selection rod drive units 30 include a first selection rod drive unit 50, a second selection rod drive unit 52, a third selection rod drive unit 54, a fourth selection rod drive unit 56, and a fifth selection rod drive unit 58.

The first selection rod drive unit 50 is a drive unit that moves the first selection rod 40 up and down. Similarly, the second selection rod drive unit 52 is a drive unit that moves the second selection rod 42 up and down, the third selection rod drive unit 54 is a drive unit that moves the third selection rod 44 up and down, the fourth selection rod drive unit 56 is a drive unit that moves the fourth selection rod 46 up and down, and the fifth selection rod drive unit 58 is a drive unit that moves the fifth selection rod 48 up and down.

Each of the selection rod drive units 50, 52, 54, 56, and 58 has a drive main body portion formed of a cylinder or the like, and a connection portion connected to the second end of the selection rod 28. The positional relationship between the drive main body portion, the connection portion, and the second end of the selection rod 28 will be explained using FIG. 4.

Figure 4 is a schematic plan view showing multiple selection rod drive units 30 and second ends 40B, 42B, 44B, 46B, and 48B of selection rods 28 connected to each selection rod drive unit 30.

As shown in FIG. 4, the first selection rod drive unit 50 has a first drive body unit 50A and a first connection unit 50B. Similarly, the second selection rod drive unit 52 has a second drive body unit 52A and a second connection unit 52B, the third selection rod drive unit 54 has a third drive body unit 54A and a third connection unit 54B, the fourth selection rod drive unit 56 has a fourth drive body unit 56A and a fourth connection unit 56B, and the fifth selection rod drive unit 58 has a fifth drive body unit 58A and a fifth connection unit 58B.

The second end 40B of the first selection rod 40 is connected to the first connection portion 50B. Similarly, the second end 42B of the second selection rod 42 is connected to the second connection portion 52B, the second end 44B of the third selection rod 44 is connected to the third connection portion 54B, the second end 46B of the fourth selection rod 46 is connected to the fourth connection portion 56B, and the second end 48B of the fifth selection rod 48 is connected to the fifth connection portion 58B.

The drive main body parts 50A, 52A, 54A, 56A, 58A move the connection parts 50B, 52B, 54B, 56B, 58B up and down in the Z direction, thereby moving the selection rods 40, 42, 44, 46, 48 up and down. The second ends 40B, 42B, 44B, 46B, 48B of the selection rods 40, 42, 44, 46, 48 are fixed to the connection parts 50B, 52B, 54B, 56B, 58, respectively.

All of the configurations shown in FIG. 4 move linearly in the XY direction together with the anvil body 20, but do not have the function of rotating within the XY plane. In other words, even if the anvil body 20 rotates within the XY plane, the selection rod drive units 50, 52, 54, 56, 58 and the second ends 40B, 42B, 44B, 46B, 48B do not rotate, and maintain the relative positional relationship in the XY direction shown in FIG. 4.

Returning to FIG. 3, the connecting portion 32 is a member that connects the first ends 40A, 42A, 44A, 46A, 48A of the multiple guide pins 26 and the multiple selection rods 28 to the anvil body 20. The connecting portion 32 is composed of a cylindrical case (not shown) that houses the multiple guide pins 26 and is fixed to the anvil body 20, but detailed structure will not be described or illustrated.

As indicated by the arrow X2, the multiple guide pins 26 are connected to the anvil body 20 in a row along the X direction.

The connecting portion 32 allows the multiple guide pins 26 and the first ends 40A, 42A, 44A, 46A, 48A of the multiple selection rods 28 to rotate together when the anvil body 20 rotates within the XY plane around the rotation axis C, as shown by the arrow XY2. The positional relationship in which the guide pins 26 are aligned in a row is maintained even when rotating together with the anvil body 20.

The second ends 40B, 42B, 44B, 46B, and 48B of the selection rods 28 are not connected to the anvil body 20 by the connecting parts 32. Therefore, when the anvil body 20 rotates around the rotation axis C, each selection rod 28 is twisted, and depending on the rotational positions of the first ends 40A, 42A, 44A, 46A, and 48A of the selection rods 28, the selection rods 28 may interfere with each other and may not be able to rotate any further.

In the component mounting device 1 of the first embodiment, the arrangement of the multiple selection rods 28 is designed to ensure that the rotation range of the anvil unit 12 is 180 degrees or more, and in particular, the arrangement of the second ends 40B, 42B, 44B, 46B, and 48B is designed to ensure that the rotation range of the anvil unit 12 is 180 degrees or more. Specific details are described using Figure 5 onwards.

Figure 5 is a schematic plan view showing the positional relationship in the XY direction between the first ends 40A, 42A, 44A, 46A, and 48A and the second ends 40B, 42B, 44B, 46B, and 48B of the selection rod 28.

As shown in FIG. 5, the first ends 40A, 42A, 44A, 46A, and 48A are arranged along a row X3 extending in the X direction. As described above, the first ends 40A, 42A, 44A, 46A, and 48A are parts that rotate together with the anvil body 20 (see arrows XY2) and rotate around the rotation axis C of the anvil body 20. In the first embodiment, of the first ends 40A, 42A, 44A, 46A, and 48A, the first end 44A located in the center is arranged to coincide with the rotation axis C of the anvil unit 12.

As shown in FIG. 5, the second ends 40B, 42B, 44B, 46B, and 48B are arranged at positions offset from the row X3. In particular, in the first embodiment, the second ends 40B, 42B, 44B, 46B, and 48B are arranged alternately with one being arranged on one side of the row X3 and the other being arranged on the other side. More specifically, the second ends 40B, 44B, and 48B are arranged on one side of the row X3 (left side of the page), and the second ends 42B and 46B are arranged on the other side of the row X3 (right side of the page).

The first ends 40A, 42A, 44A, 46A, and 48A have center positions 40C, 42C, 44C, 46C, and 48C, respectively. Similarly, the second ends 40B, 42B, 44B, 46B, and 48B have center positions 40D, 42D, 44D, 46D, and 48D, respectively. In the example shown in FIG. 5, the shapes of the first ends 40A, 42A, 44A, 46A, and 48A and the second ends 40B, 42B, 44B, 46B, and 48B are illustrated as being circular, but may be any shape.

Here, the line connecting the center positions 40C and 40D on the first selection rod 40 is defined as center line 40E. Similarly, the line connecting the center positions 42C and 42D is defined as center line 42E, the line connecting the center positions 44C and 44D is defined as center line 44E, the line connecting the center positions 46C and 46D is defined as center line 46E, and the line connecting the center positions 48C and 48D is defined as center line 48E.

The component mounting device 1 of embodiment 1 is designed so that the center lines 40E, 42E, 44E, 46E, and 48E do not intersect at any height within a total rotation range of 180 degrees, including the range of rotation of +90 degrees from the reference position and the range of rotation of -90 degrees from the reference position, with the rotation position shown in FIG. 5 as the reference position. This prevents the selection rods 28 from interfering with each other within at least a rotation range of 180 degrees, ensuring a rotation range of 180 degrees or more for the anvil unit 12.

Figures 6A and 6B are schematic plan views showing the change in position of the selection rod 28 when the anvil unit 12 rotates +90 degrees. Figure 6A shows the state rotated approximately +45 degrees, and Figure 6B shows the state rotated approximately +90 degrees.

As shown in FIG. 6A, when rotated approximately +45 degrees, the first ends 40A, 42A, 44A, 46A, and 48A are rotated +45 degrees around the rotation axis C, and none of the center lines 40E, 42E, 44E, 46E, and 48E intersect with each other. As shown in FIG. 6B, even when rotated approximately +90 degrees, the center lines 40E, 42E, 44E, 46E, and 48E do not intersect with each other. In a plan view such as FIG. 6B, for example, the center lines 40E and 42E appear to overlap, but they are in a twisted position relative to each other at the height position in the Z direction and do not intersect with each other at least until they reach a rotation position of +90 degrees. The same is true for the center lines 44E and 46E, and the center lines 44E and 48E. This ensures a rotation range of +90 degrees from the reference position.

Figures 7A and 7B are schematic plan views showing the change in position of the selection rod 28 when the anvil unit 12 rotates -90 degrees. Figure 7A shows the state rotated approximately -45 degrees, and Figure 7B shows the state rotated approximately -90 degrees.

As shown in FIG. 7A, when rotated approximately -45 degrees, the first ends 40A, 42A, 44A, 46A, and 48A are rotated -45 degrees around the rotation axis C, and none of the center lines 40E, 42E, 44E, 46E, and 48E intersect with each other. As shown in FIG. 7B, even when rotated approximately -90 degrees, the center lines 40E, 42E, 44E, 46E, and 48E do not intersect with each other. In a plan view such as FIG. 7B, for example, the center lines 46E and 48E appear to overlap, but they are in a twisted position relative to each other at the height position in the Z direction and do not intersect with each other until they reach at least a rotation position of -90 degrees. The same is true for the center lines 40E and 44E, and the center lines 42E and 44E. This ensures a rotation range of -90 degrees from the reference position.

As shown in Figures 6A to 7B, the component mounting device 1 of embodiment 1 is designed so that the center lines 40E, 42E, 44E, 46E, and 48E do not intersect with each other within a predetermined rotation range of 180 degrees, and the rotation range of the anvil unit 12 can be secured to be 180 degrees or more. This improves the rotation flexibility of the anvil unit 12.

When guiding the leads of the component 3, the two selection rods 28 are moved up and down, so the vertical positional relationship between the center lines 40E, 42E, 44E, 46E, and 48E changes, but the design takes this vertical movement of the selection rods 28 into consideration. In other words, even when each selection rod 28 is at an arbitrary height, the design ensures that the center lines 40E, 42E, 44E, 46E, and 48E do not cross each other within a specified 180-degree rotation range, as shown in Figures 6A to 7B.

In addition, each selection rod 28 is long in the Z direction and short in the X and Y directions. For example, even if the center lines 40E, 42E, 44E, 46E, and 48E do not intersect at rotation positions of +90 degrees and -90 degrees as shown in Figures 6B and 7B, the selection rods 28 may come into slight contact with each other depending on the height position. Even in such cases, the selection rods 28 are designed to elastically deform, etc., so that the effects of contact can be ignored, and the rotation range of the anvil unit 12 can be secured to 180 degrees or more.

In the above configuration, five guide pins 26 and five selection rods 28 (five sets) are provided, and two sets that move up and down are selected according to the lead pitch of the component 3. This makes it possible to handle cases where there are, for example, four different lead pitch patterns. When there are a small number of pitch patterns, the configuration of the insertion guide mechanism 24 can be simplified by appropriately removing the set of guide pins 26, selection rods 28, and selection rod drive unit 30 from the configuration of embodiment 1.

For example, as shown in FIG. 8, the set of the first selection rod 40 and the first selection rod drive unit 50 may be removed. The configuration shown in FIG. 8 can accommodate a case where there are, for example, three types of pitch patterns. Also, as shown in FIG. 9, in addition to the set of the first selection rod 40 and the first selection rod drive unit 50, the set of the fifth selection rod 48 and the fifth selection rod drive unit 58 may be further removed. The configuration shown in FIG. 9 can accommodate a case where there are, for example, two types of pitch patterns. In addition, in the configuration shown in FIG. 9, for example, the second selection rod 42 and the second selection rod drive unit 52 may be further omitted, and the guide pin 26 corresponding to the omitted second selection rod 42 may be kept in a constantly elevated state. Even in such a case, it is possible to similarly accommodate a case where there are two types of pitch patterns.

In addition, in the component mounting device 1 of embodiment 1, the rotation range of the anvil unit 12 is secured to be 180 degrees or more, and the connection structure between the anvil body 20 and the hose 22 (Figure 1) is also devised. The details are explained using Figure 10.

Figure 10 is a schematic perspective view showing the connection structure 34 that connects the anvil body 20 and the hose 22.

As shown in FIG. 10, the connection structure 34 includes a first connection portion 36 and a second connection portion 38. The first connection portion 36 and the second connection portion 38 are connected to each other, and the first connection portion 36 is fixed to the anvil body portion 20, and the second connection portion 38 is fixed to the hose 22. Inside the first connection portion 36 and the second connection portion 38, a storage space (not shown) is formed for storing lead scraps.

In the first embodiment, the first connection part 36 and the second connection part 38 are connected to be rotatable relative to each other. Specifically, the first connection part 36 and the second connection part 38 are connected to be rotatable relative to each other about a rotation axis S that is different from the rotation axis C of the anvil body part 20. With this configuration, even when the anvil body part 20 rotates about the rotation axis C as shown by the arrow XY2, the first connection part 36 and the second connection part 38 can rotate relative to each other to absorb the influence of the rotation of the anvil body part 20. This makes it possible to suppress unnecessary rotation of the hose 22 and prevent the hose 22 from breaking.

As described above, the anvil unit 12 of this embodiment includes an anvil body 20, a plurality of guide pins 26, a plurality of selection rods 28, a plurality of selection rod drive units 30, and a connecting unit 32. The anvil body 20 has a lead processing unit 18 that processes the leads of the component 3 inserted into the insertion hole 17 of the substrate 2, and has a rotation function. The plurality of guide pins 26 are inserted into the insertion hole 17 of the substrate 2 and guide the leads of the component 3 toward the insertion hole 17. The plurality of selection rods 28 are provided corresponding to the plurality of guide pins 26, respectively, and have first ends 40A, 42A, 44A, 46A, 48A that are coupled to the guide pins 26, and second ends 40B, 42B, 44B, 46B, 48B. The selection rod driving units 30 are provided corresponding to the selection rods 28, respectively, and are coupled to the second ends 40B, 42B, 44B, 46B, 48B of the selection rods 28 to move the selection rods 28 up and down. The connecting unit 32 connects the guide pins 26 and the first ends 40A, 42A, 44A, 46A, 48A of the selection rods 28 to the anvil body 20 so as to rotate with the rotation of the anvil body 20. In this configuration, the second ends 40B, 42B, 44B, 46B, 48B of the selection rods 28 are fixed in position by the selection rod driving units 30. Furthermore, the positions of the second ends 40B, 42B, 44B, 46B, 48B are set so that while the rotational positions of the first ends 40A, 42A, 44A, 46A, 48A of the multiple selection rods 28 are within a predetermined range (180 degrees in embodiment 1), the center lines 40E, 42E, 44E, 46E, 48E connecting the center positions 40C, 42C, 44C, 46C, 48C of the first ends 40A, 42A, 44A, 46A, 48A of each selection rod 28 and the center positions 40D, 42D, 44D, 46D, 48D of the second ends 40B, 42B, 44B, 46B, 48B do not intersect with each other at any height position.

With this configuration, the rotation range of the anvil body 20 can be set to, for example, 180 degrees or more while preventing interference between the selection rods 28, improving the rotation flexibility of the anvil unit 12. This increases the variety of orientations in which the component 3 can be inserted into the board 2, and widens the rotation range that the anvil unit 12 can accommodate. In addition, the positions of the second ends 40B, 42B, 44B, 46B, 48B can be determined based on the center positions 40C, 42C, 44C, 46C, 48C of the first ends 40A, 42A, 44A, 46A, 48A and the center positions 40D, 42D, 44D, 46D, 48D of the second ends 40B, 42B, 44B, 46B, 48B, making design easier.

The rotation range of the anvil body 20 is not limited to 180 degrees or more, and may be any other angle range (e.g., less than 180 degrees). Also, the center lines 40E, 42E, 44E, 46E, 48E may not be designed to intersect with each other, and lines connecting any position of the first ends 40A, 42A, 44A, 46A, 48A and any position of the second ends 40B, 42B, 44B, 46B, 48B may not be designed to intersect with each other.

In addition, in the anvil unit 12 of this embodiment, five guide pins 26, five selection rods 28, and five selection rod 28 drive units are provided, and the first ends 40A, 42A, 44A, 46A, and 48A of the five selection rods 28 are arranged in a row X3 when viewed in a plan view along the rotation axis C of the anvil body 20.

With this configuration, by providing five selection rods 28, even if the pitch of the insertion holes 17 of the substrate 2 changes, it is possible to accommodate a plurality of pitches by selectively moving the selection rods 28 up and down. Also, as the number of selection rods 28 increases, interference between the selection rods 28 becomes more likely to occur, but by presetting the positions of the second ends 40B, 42B, 44B, 46B, and 48B of the selection rods 28, interference between the selection rods 28 can be prevented.

In addition, in the anvil unit 12 of this embodiment, the first end 44A, which is one of the first ends 40A, 42A, 44A, 46A, and 48A of the five selection rods 28, is located in a position overlapping with the rotation axis C of the anvil body 20.

With this configuration, by providing one selection rod 28 that does not rotate in sync with the anvil body 20, it can be used as a reference selection rod 28.

In addition, in the anvil unit 12 of this embodiment, the second end 44B corresponding to the first end 44A that overlaps with the rotation axis C is positioned at a position offset from the first end 44A when viewed in a plane along the rotation axis C.

With this configuration, by shifting the positions of the first end 44A that overlaps the rotation axis C and the corresponding second end 44B, interference between the selection rods 28 can be effectively prevented.

In addition, in the anvil unit 12 of this embodiment, the second ends 40B, 42B, 44B, 46B, and 48B of the five selection rods 28 are positioned on either one side or the other side of the row X3 formed by the first ends 40A, 42A, 44A, 46A, and 48A when viewed in a plane along the rotation axis C of the anvil body 20.

With this configuration, the second ends 40B, 42B, 44B, 46B, and 48B are offset from the row X3 of the first ends 40A, 42A, 44A, 46A, and 48A, making it possible to design the second ends 40B, 42B, 44B, 46B, and 48B so that they are distributed in a well-balanced manner.

In addition, in the anvil unit 12 of this embodiment, the second ends 40B, 42B, 44B, 46B, 48B of the five selection rods 28 are arranged alternately with those arranged on one side (40B, 44B, 48B) and those arranged on the other side (42B, 46B) of the row X3 formed by the first ends 40A, 42A, 44A, 46A, 48A.

This configuration makes it possible to design the second ends 40B, 42B, 44B, 46B, and 48B so that they are distributed in a well-balanced manner.

In addition, in the anvil unit 12 of this embodiment, the lead processing section 18 processes the leads of the component 3 by bending them.

This configuration allows the component 3 to be mounted on the board 2 with high precision.

The component mounting device 1 of this embodiment also includes a board positioning unit 6 that positions the board 2 at a predetermined mounting position, a mounting head 10 that picks up the component 3 and inserts the leads of the component 3 into the board 2 positioned at the mounting position, and an anvil unit 12 that has a lead processing unit 18 that processes the leads of the component 3.

This configuration can achieve the same effects as the anvil unit 12 described above.

(Embodiment 2)
An anvil unit according to a second embodiment of the present invention and a component mounting apparatus using the same will be described. In the second embodiment, differences from the first embodiment will be mainly described, and descriptions that overlap with the first embodiment will be omitted.

In the second embodiment, the arrangement of the selection rods is different from that of the first embodiment. In particular, the second embodiment differs from the first embodiment in that the extension directions of the selection rods in the reference position are all aligned vertically.

Figure 11 is a schematic plan view of multiple selection rods 62 in an anvil unit 60 of embodiment 2. Figure 12 is a schematic plan view showing multiple selection rod drive units 64 and second ends 70B, 72B, 74B, 76B, and 78B of the selection rods 62 connected to each selection rod drive unit 64.

The multiple selection rods 62 shown in FIG. 11 include a first selection rod 70, a second selection rod 72, a third selection rod 74, a fourth selection rod 76, and a fifth selection rod 78.

As shown in FIG. 11, when the selection rods 70, 72, 74, 76, 78 in the reference position are viewed in a plane along the rotation axis C, the first ends 70A, 72A, 74A, 76A, 78A overlap with the second ends 70B, 72B, 74B, 76B, 78B. Specifically, the first end 70A overlaps with the second end 70B, and the center line 70E connecting the center position of the first end 70A and the center position of the second end 70B also overlaps. Similarly, the first end 72A overlaps with the second end 72B and the center line 72E, the first end 74A overlaps with the second end 74B and the center line 74E, the first end 76A overlaps with the second end 76B and the center line 76E, and the first end 78A overlaps with the second end 78B and the center line 78E.

The multiple selection rod drive units 64 shown in FIG. 12 include a first selection rod drive unit 80, a second selection rod drive unit 82, a third selection rod drive unit 84, a fourth selection rod drive unit 86, and a fifth selection rod drive unit 88.

The first selection rod drive 80 has a first drive body 80A and a first connection 80B, and the second end 70B is connected to the first connection 80B. Similarly, the second selection rod drive 82 has a second drive body 82A and a second connection 82B, and the second end 72B is connected to the second connection 82B, the third selection rod drive 84 has a third drive body 84A and a third connection 84B, and the second end 74B is connected to the third connection 84B, the fourth selection rod drive 86 has a fourth drive body 86A and a fourth connection 86B, and the second end 76B is connected to the fourth connection 86B, and the fifth selection rod drive 88 has a fifth drive body 88A and a fifth connection 88B, and the second end 78B is connected to the fifth connection 88B.

In the example shown in FIG. 12, the height positions of the connection parts 80B, 82B, 84B, 86B, and 88B in the Z direction are shifted to prevent them from interfering with each other, but this is not limited to the above case. Connection parts with a planar shape different from that of embodiment 1 may be used and placed at the same height.

Even with the arrangement of the selection rods 70, 72, 74, 76, and 78 shown in Figures 11 and 12, the rotation range of the anvil unit 60 can be secured to be 180 degrees or more. Specific details will be explained using Figures 13 and 14.

Figure 13 is a schematic plan view showing the change in position of the selection rods 70, 72, 74, 76, and 78 when the anvil unit 60 rotates +90 degrees, and Figure 14 is a schematic plan view showing the change in position of the selection rods 70, 72, 74, 76, and 78 when the anvil unit 60 rotates -90 degrees.

As shown in FIG. 13, when rotated +90 degrees from the reference position, center lines 70E, 72E, 74E, 76E, and 78E do not intersect with each other. Similarly, as shown in FIG. 14, when rotated -90 degrees from the reference position, center lines 70E, 72E, 74E, 76E, and 78E do not intersect with each other.

As shown in Figures 13 and 14, the center lines 70E, 72E, 74E, 76E, and 78E are designed not to intersect with each other within a predetermined rotation range of 180 degrees, and the rotation range of the anvil unit 60 can be ensured to be 180 degrees or more. As in the first embodiment, the design also takes into consideration the vertical movement of each selection rod 62, and the center lines 70E, 72E, 74E, 76E, and 78E are designed not to intersect with each other within a predetermined rotation range of 180 degrees, even when each selection rod 62 is at any height position.

As described above, in the anvil unit 60 of the second embodiment, the positions of the second ends 70B, 72B, 74B, 76B, 78B of the five selection rods 62 are set so that the center lines 70E, 72E, 74E, 76E, 78E connecting the center positions of the first ends 70A, 72A, 74A, 76A, 78A of each selection rod 62 and the center positions of the second ends 70B, 72B, 74B, 76B, 78B do not intersect with each other at any height position while the rotational positions of the first ends 70A, 72A, 74A, 76A, 78A are within a predetermined range of 180 degrees.

With this configuration, the rotation range of the anvil body 20 can be set to 180 degrees or more while preventing interference between the selection rods 62, improving the rotation flexibility of the anvil unit 60. This increases the variety of orientations in which the component 3 can be inserted into the board 2, and widens the rotation range that the anvil unit 60 can accommodate. In addition, the positions of the second ends 70B, 72B, 74B, 76B, 78B can be determined based on the central positions of the first ends 70A, 72A, 74A, 76A, 78A and the central positions of the second ends 70B, 72B, 74B, 76B, 78B, making design easier.

Comparing the above-mentioned first and second embodiments, the second embodiment ensures a wide rotation range for the selection rod 62, while the first embodiment uses the same shaped connection parts 50B, 52B, 54B, and 56B as shown in FIG. 4, and can be positioned at the same height. Therefore, this can be easily achieved by improving or repurposing the conventional model.

Although the present invention has been described above with reference to the above-mentioned embodiments, the present invention is not limited to the above-mentioned embodiments. For example, in the first and second embodiments, the case where five selection rods 28, 62 are provided is described, but the present invention is not limited to such a case, and as shown in FIG. 9, it is sufficient to provide at least two selection rods, at least two guide pins, and at least two selection rod drive units.

When arranging the selection rods 28, 62 in a row along the row X3, at least three selection rods 28, 62 may be provided. In this case, as in the first and second embodiments, the first ends of the at least three selection rods 28, 62 may be arranged in a row X3 when viewed in a plane along the rotation axis C of the anvil body 20, and any one of the first ends may be arranged in a position overlapping the rotation axis C of the anvil body 20. In this case, as in the first embodiment, the second end corresponding to the first end overlapping the rotation axis C may be arranged in a position shifted from the first end when viewed in a plane along the rotation axis C. In this case, as in the first embodiment, the second ends of the at least three selection rods 28 may be arranged on either one side or the other side of the row X3 formed by the first ends of the selection rods 28, 62 when viewed in a plane along the rotation axis C of the anvil body 20. In this case, as in embodiment 1, the second ends of at least three selection rods 28 may be arranged alternately on one side and the other side of the row X3 formed by the first ends.

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, by appropriately combining any of the various modifications of the above embodiment, it is possible to achieve the effects of each of them.

The present invention can be applied to any anvil unit and component mounting device equipped with the same.
