Description

This specification discloses a feeder status display system and feeder-related technology that are applied to a component mounting line in which multiple component mounters are arranged along the transport path of circuit boards.

In recent years, as described in Patent Document 1 (International Publication WO2017/141365), there has been a component mounting line in which a feeder storage unit for storing feeders to be set in the feeder set units of multiple component mounters that make up the component mounting line and feeders removed from the feeder set units is located upstream of the component mounting line, and an automatic exchange device is moved across the feeder storage unit and multiple component mounters so that the automatic exchange device removes feeders from the feeder storage unit and sets them in the feeder set units of one of the component mounters, and also retrieves feeders removed from the feeder set units of one of the component mounters back into the feeder storage unit.

In a component mounting line equipped with such an automatic exchange device, as described in Patent Document 2 (International Publication WO2018/127956), a feeder transport device is arranged to move between a work area where a worker works and a feeder storage, and at the work area, the worker loads a replacement feeder onto the feeder transport device, which transports the replacement feeder to the feeder storage, where the feeder transport device transfers the replacement feeder to the feeder storage, and transfers the replaced feeder that has been collected in the feeder storage onto the feeder transport device before returning to the work area.

International Publication No. WO2017/141365 International Publication No. WO2018/127956

In a component mounting line equipped with an automatic exchange device as described in Patent Documents 1 and 2 above, the automatic exchange device automatically performs the feeder exchange work for the feeder setting section of each component mounting machine, so workers perform the work of replenishing and retrieving feeders from a feeder storage located upstream of the component mounting line, or perform the work of replenishing and retrieving feeders from a feeder transport device at a work site away from the component mounting line.

Some of the feeders that workers retrieve from the feeder storage or feeder transport device can be reused in later production, but there are also feeders that cannot be reused in their current state (feeders that require adjustment work, tape reel replacement work, etc.), such as feeders that stopped during production due to an error such as a component pickup error, or feeders that are out of parts or have only a few parts remaining.

However, since it is difficult for workers to visually determine from the appearance of a feeder loaded in a feeder storage unit or feeder transport device whether it is reusable or not, there is a possibility that a worker may mistakenly determine that a feeder retrieved from a feeder storage unit or feeder transport device is reusable and reuse it as is, even if the feeder cannot be reused as it is.

The invention of claim 1 is applied to a component mounting line including a plurality of component mounting machines arranged along a transport path for circuit boards, and a feeder storage unit for storing feeders to be set in the feeder set units of the plurality of component mounting machines and feeders removed from the feeder set units, and is characterized in that it comprises a status display unit provided on the end face or upper end face on the removal direction side of the feeder and displays the status of the feeder, a rewritable non-volatile memory unit provided in the feeder and storing and holding information on the status of the feeder to be displayed on the status display unit, a control unit for storing information on the status of the feeder set in the feeder set unit during production in the memory unit, and a power supply unit provided in the feeder storage unit for supplying power to the feeder recovered from the component mounting machine to the feeder storage unit, and displaying the status of the feeder stored and held in the memory unit of the feeder on the status display unit.

In this configuration, a status display unit is provided on the end face or upper end face of the feeder stored in the feeder storage unit in the removal direction, which is a position that is easily visible from the worker's side, and this status display unit displays the status of the feeder. Therefore, the worker can easily know the status of the feeder just by looking at the display on the status display unit of the feeder stored in the feeder storage unit. This allows the worker to easily determine by visual inspection alone whether the feeder to be retrieved from the feeder storage unit can be reused in its current state.

The following describes the two examples 1 and 2 disclosed in this specification.

Example 1 will be explained using Figures 1 to 10.

First, the configuration of the component mounting line 10 will be explained using Figures 1 to 3.

The component mounting line 10 is configured by arranging multiple component mounters 12 along the transport direction (X direction) of the circuit board 11, and on the board carrying-in side of the component mounting line 10, a solder printer (not shown) that prints solder on the circuit board 11 and a feeder storage 19 that stores cassette-type feeders 14 (see Figures 4 and 5) are installed.

As shown in FIG. 2, each component mounter 12 is equipped with two conveyors 13 for transporting circuit boards, a mounting head 15 that holds replaceable suction nozzles (not shown) that pick up components supplied from a cassette-type feeder 14 and mount them on the circuit board 11, a head moving device 16 that moves the mounting head 15 in the XY directions (left-right, front-back, and rear-facing directions), and a display device 23 such as an LCD display or CRT (see FIG. 1).

Each component mounter 12 on the component mounting line 10 transports the circuit board 11 conveyed from the upstream component mounter 12 to a predetermined position using a conveyor 13, clamps the circuit board 11 using a clamping mechanism (not shown), picks up components supplied from a cassette-type feeder 14 using the suction nozzle of the mounting head 15, moves it from the suction position to an imaging position, images the component from its underside using a component imaging camera (not shown) to determine the amount of deviation in the suction position of the component, and then moves the mounting head 15 above the circuit board 11 to correct the amount of deviation in the suction position of the component, and mounts the component on the circuit board 11 to produce a component-mounted board.

Next, the configuration of the cassette type feeder 14 will be described with reference to FIGS.
4 and 5, a reel accommodating space 33 is provided within a thin box-shaped feeder body 31 of the feeder 14 for replaceably (detachably) accommodating a tape reel 32 around which a component supply tape (not shown) is wound. A reel cover 34 for covering the lower portion of the tape reel 32 is provided at the lower portion of the reel accommodating space 33. A reel presser 35 for holding the tape reel 32 set in the reel accommodating space 33 in a set state is provided at the upper portion of the reel accommodating space 33 so as to be pivotable to open and close with both sides of its upper end as fulcrums.

When removing the tape reel 32 from the reel storage space 33, the reel holder 35 is rotated upward around both upper ends thereof as fulcrums to open the upper part of the reel storage space 33, and the upper part of the tape reel 32 in the reel storage space 33 is grasped by hand and tilted slightly toward the front while the tape reel 32 is pulled out diagonally upward. When setting the tape reel 32 in the reel storage space 33, the lower part of the tape reel 32 is inserted diagonally upward into the inside of the reel cover 34 in the reel storage space 33 with the reel holder 35 open, and the setting of the tape reel 32 in the reel storage space 33 is completed by closing the reel holder 35.

In this case, a short shaft (not shown) that fits into the central hole 36 of the tape reel 32 may be provided in the center of the reel storage space 33, and the short shaft may rotatably support the tape reel 32. When adopting this configuration, it is preferable to make the length of the shaft shorter than the length of the central hole 36 of the tape reel 32 (for example, 1/2 to 1/3 the length) so that the shaft that fits into the central hole 36 of the tape reel 32 does not hinder the attachment and detachment of the tape reel 32. Alternatively, multiple rollers (not shown) may be provided along the outer periphery of the tape reel 32 on the lower side of the reel storage space 33, and the outer periphery of the tape reel 32 may be rotatably supported by these multiple rollers.

A component suction position for suctioning components with a suction nozzle (not shown) of the component mounter 12 (see FIG. 2) is set at a position on the upper end surface of the feeder body 31 close to the end surface on the mounting direction side of the feeder body 31. A tape guide 37 is provided below the upper end surface of the feeder body 31 to guide the component supply tape pulled out from the tape reel 32 to the component suction position.

The space between the reel storage space 33 and the end surface of the feeder body 31 in the mounting direction side of the feeder body 31 is the electrical equipment storage space 40. In this electrical equipment storage space 40, various electrical equipment such as a tape feed device 38 (see FIG. 9) that pulls out the component supply tape from the tape reel 32 in the reel storage space 33 and pitch-feeds it to the component suction position, a control unit 39 (see FIG. 9) that controls the pitch-feed operation, and a rewritable non-volatile memory unit 41 that stores and holds information on the state of the feeder 14, which will be described later, are provided. The rewritable non-volatile memory unit 41 is composed of a storage medium (e.g., a flash memory, an EEPROM, a HDD, an SSD, etc.) that can write data while the power is on and that retains the stored data even when the power is off.

Two positioning pins 42, 42 (positioning parts) for positioning with respect to the feeder set part 51 (see Figures 6 and 7) of the component mounter 12 are provided at a predetermined interval in the vertical direction on the end face part of the mounting direction side of the feeder body 31 at a position higher than the center in the height direction (in this embodiment 1, a position close to the upper end face part of the feeder body 31). Between these two positioning pins 42, 42, a connector 43 for both power supply and communication is provided, and by inserting and connecting the connector 43 of the feeder body 31 to the connector 52 (see Figure 9) on the component mounter 12 side, power is supplied from the component mounter 12 side to various electrical components such as the tape feed device 38, control unit 39, and memory unit 41 in the feeder body 31, and various signals such as control signals and sensor signals are transmitted and received between the control unit 20 (see Figure 9) of the component mounter 12 and the control unit 39 of the feeder body 31.

Next, we will explain the configuration for holding the feeder body 31 in a set state in the feeder set section 51 (the space that houses the feeder 14) of the component mounter 12.

On the upper end surface of the feeder body 31, on the upper side portion of the reel storage space 33, a guide rail 45 with a T-shaped cross section is provided as an upper holding member so as to extend in the attachment/detachment direction of the feeder body 31. Correspondingly, on the upper side member 51a of the feeder set unit 51 of the component mounter 12, a slot groove 46 with a T-shaped cross section (see Figures 6 and 7) is provided so as to extend in the attachment/detachment direction of the feeder body 31, into which the guide rail 45 with a T-shaped cross section of the feeder body 31 can slide in the attachment/detachment direction of the feeder body 31, and the guide rail 45 with a T-shaped cross section of the feeder body 31 fits into the slot groove 46 with a T-shaped cross section of the feeder set unit 51, so that the slide movement of the feeder body 31 in the attachment/detachment direction is guided and the feeder body 31 is held in a state where it is prevented from falling out downward. As shown in FIG. 6, multiple slot grooves 46 are provided at a predetermined interval on the upper side of the feeder setting section 51, so that multiple feeder bodies 31 can be set in the feeder setting section 51.

In addition, a clamp device 54 (see FIG. 7) is provided at a position on the upper end surface of the feeder body 31 near the end surface of the feeder body 31 in the removal direction, which clamps the feeder body 31 to the feeder set unit 51 of the component mounter 12 in an attached state. The clamp device 54 includes a clamp member 55 that protrudes obliquely upward from the upper end surface of the feeder body 31 during clamping operation, a spring 56 such as a spring that urges the clamp member 55 obliquely upward in the clamping direction, and an operating lever 57 (operating unit) that operates the clamp release operation to retract the clamp member 55 obliquely downward in the clamp release direction. The operating lever 57 is arranged to protrude from the end surface of the feeder body 31 in the removal direction. When the automatic exchange device 26 described later automatically exchanges the feeder 14 with respect to the feeder set unit 51 of the component mounter 12, the automatic exchange device 26 holds the clamp device 54 in an unclamped state.

On the other hand, a clamp hole 61 (see FIG. 7) is provided at the upper side of the feeder set section 51 of the component mounter 12 at a position corresponding to the clamp member 55, and the clamp member 55 fits into this clamp hole 61 to clamp the feeder body 31 in the attached state. In this case, as shown in FIG. 7, the spring 56 pushes the clamp member 55 diagonally upward in the removal direction of the feeder body 31, so that the upper end of the clamp member 55 is pressed against the side of the clamp hole 61 in the removal direction of the feeder body 31, and the reaction force presses the feeder body 31 toward the attachment direction, so that the feeder body 31 is positioned accurately and the connection state of the connectors 43, 52 is maintained.

4 and 5, an I-shaped cross-section guide rail 58 is provided on the lower end surface of the feeder body 31 as a lower holding member, extending in the attachment/detachment direction of the feeder body 31. Correspondingly, a lower member (not shown) of the feeder set unit 51 of the component mounter 12 is provided with an I-shaped cross-section rail groove (not shown) into which the I-shaped cross-section guide rail 58 of the feeder body 31 can slide in the attachment/detachment direction of the feeder body 31, and the I-shaped cross-section guide rail 58 of the feeder body 31 fits into the I-shaped cross-section rail groove on the lower side of the feeder set unit 51, thereby guiding the slide movement of the feeder body 31 in the attachment/detachment direction and holding it in a state where it is not prevented from falling out upward. This prevents the frictional resistance from increasing when the feeder body 31 slides in the attachment/detachment direction, even if there is some manufacturing variation in the height dimension of the feeder set section 51 of the component mounter 12 or the height dimension of the feeder body 31, and allows the feeder body 31 to be attached and detached smoothly.

As shown in Figures 4 and 5, a status display unit 65 that displays the status of the feeder 14 is provided at a position lower than the center in the height direction on the end surface of the feeder body 31 in the removal direction. In this embodiment 1, as shown in Figure 8, the status display unit 65 is configured by arranging multiple light-emitting elements 66, 67, and 68 such as LEDs, which emit light of different colors, in a vertical row.

In this embodiment 1, the light emitting element 66 at the bottom position emits green light, and when power is being supplied to the feeder 14, the light emitting element 66 emits green light (lights up) to indicate that power is being supplied. The light emitting element 67 at the middle position emits yellow light, and when the number of remaining parts on the component supply tape wound on the tape reel 32 falls below a predetermined value, the light emitting element 67 at the middle position flashes yellow to indicate that the number of remaining parts is below a predetermined value (there is about to run out of parts). Furthermore, when there is a run out of parts, the light emitting element 67 at the middle position emits yellow light (lights up) to indicate that there is a run out of parts. The light emitting element 68 at the top position emits red light, and when an abnormality occurs in the component supply operation (tape feed operation) of the feeder 14 and an error stop occurs, the light emitting element 68 at the top position emits red light (lights up) to indicate that there is an abnormality in the component supply operation of the feeder 14. In addition, when it is determined that maintenance of the feeder 14 is necessary based on the occurrence rate of component pickup errors during production, the light-emitting element 68 at the top position flashes red to indicate that maintenance of the feeder 14 is necessary.

The control unit 20 of the component mounter 12 monitors the status of the feeder 14 set in the feeder set unit 51 during production (e.g., whether there is an abnormality in the component supply operation, whether there is a shortage of components, whether the shortage of components is below a predetermined value, whether maintenance is required, etc.), and transfers the status information of the feeder 14 to the feeder 14 and stores it in the memory unit 41. Alternatively, the control unit 39 of the feeder 14 may monitor the status of the feeder 14 and store the status information of the feeder 14 in the memory unit 41. The control unit 20 of the component mounter 12 may also display the status of the feeder 14 set in the feeder set unit 51 during production on the display unit 23 on the top of the component mounter 12.

As shown in Figure 1, an automatic exchange device 26 that automatically exchanges (sets and removes) feeders 14 for the feeder set units 51 of multiple component mounters 12 is installed at the front side of the component mounting line 10 so as to move across the feeder storage 19 and multiple component mounters 12. Below the feeder set units 51 of each component mounter 12, a stock unit 71 is provided that temporarily stores the feeders 14 to be automatically exchanged for the feeder set units 51 of that component mounter 12. The automatic exchange device 26 sets the feeder 14 taken out of the feeder storage 19 in the feeder set section 51 or stock section 71 of one of the component mounters 12, sets the feeder 14 taken out of the stock section 71 of one of the component mounters 12 in the feeder set section 51 of that component mounter 12, recovers the feeder 14 removed from the feeder set section 51 of one of the component mounters 12 to the stock section 71 of that component mounter 12, or recovers the feeder 14 removed from the feeder set section 51 or stock section 71 of that component mounter 12 to the feeder storage 19.

The feeder storage 19 is provided with a number of slots (not shown) for setting a number of feeders 14, similar to the feeder setting unit 51 of the component mounter 12, and each slot is provided with a connector 81 (see FIG. 10) for both power supply and communication, which functions as a power supply unit. Each feeder 14 stored in the feeder storage 19 has its connector 43 inserted into the connector 81 on the feeder storage 19 side, so that power is supplied from the feeder storage 19 to various electrical components such as the tape feed device 38, control unit 39, and memory unit 41 in each feeder 14. As a result, the control unit 82 of the feeder storage 19 communicates with the control unit 39 of each feeder 14 to obtain the identification information (feeder ID) of each feeder 14 and recognize the type of each feeder 14 and the position of the slot in which each feeder 14 is set. In addition, the control unit 39 of each feeder 14 stored in the feeder storage 19 causes the status display unit 65 to display the status of the feeder 14 stored in the memory unit 41 of the feeder 14.

As shown in FIG. 3, the control unit 20 of each mounter 12 in the component mounting line 10, the control unit 82 of the feeder storage 19, and the control unit 27 of the automatic exchanger 26 are connected to a production management computer 70 that manages the entire component mounting line 10 via a network 28 such as a wired LAN or wireless LAN so that they can communicate with each other, and the production management computer 70 manages the operation of each mounter 12 in the component mounting line 10 and the operation of the automatic exchanger 26.

Furthermore, the component mounting line 10 of this embodiment 1 is equipped with a feeder transport device 76 (see FIG. 1) that automatically travels between the work area where the worker works and the feeder storage 19. At the work area, the worker loads the replacement feeder 14 onto the feeder transport device 76, which transports it to the feeder storage 19. The feeder transport device 76 transfers the replacement feeder 14 to the feeder storage 19, and also loads the replaced feeder 14 that has been collected in the feeder storage 19 onto the feeder transport device 76 and returns to the work area. In this way, at a work area away from the feeder storage 19, the worker can efficiently replenish the replacement feeder 14, replace the tape reel 32 of the collected replaced feeder 14, and perform maintenance and repairs. The feeder transport device 76 is equipped with a feeder transfer mechanism (not shown) that transfers the feeder 14 between the feeder storage 19 and the feeder storage 19.

Although not shown, the feeder transport device 76, like the feeder storage 19, has multiple slots for setting multiple feeders 14, and each slot has a connector that functions as a power supply unit. Each feeder 14 loaded on the feeder transport device 76 receives power from the feeder transport device 76 by inserting and connecting its connector 43 into a connector on the feeder transport device 76 side. As a result, the control unit 39 of each feeder 14 loaded on the feeder transport device 76 displays the status of that feeder 14 stored and held in the memory unit 41 of that feeder 14 on the status display unit 65 of that feeder 14.

The production management computer 70 communicates with the feeder carrying device 76 via a wireless LAN or the like, and also manages the operation of the feeder carrying device 76. In this embodiment 1, the work area where the workers work and the feeder carrying device 76 are shared by multiple component mounting lines 10. In this way, the same worker can replenish the feeders 14 for replacement in the feeder storage 19 of the multiple component mounting lines 10, replace the tape reels 32 of the replaced feeders 14 collected from the multiple component mounting lines 10, and perform maintenance and repairs in a common work area. There is no need to provide a work area or feeder carrying device 76 for each component mounting line 10. This allows multiple component mounting lines 10 to be installed compactly in a factory, and the number of workers engaged in managing the multiple component mounting lines 10 can be reduced, making it possible to further reduce labor.

Even if the feeder transport device 76 is present, the supply and retrieval of feeders 14 from the feeder storage 19 of the component mounting line 10 may be performed manually by an operator, and it is up to the operator to decide whether or not to use the feeder transport device 76.

While some of the feeders 14 that workers retrieve from the feeder storage 19 or feeder transport device 76 can be reused in later production, there are also feeders that cannot be reused in their current state (feeders that require adjustment work, tape reel replacement work, etc.), such as feeders that stopped during production due to an error such as a component pickup error, or feeders that are out of parts or have only a few parts remaining.

In this regard, in this embodiment 1, a status display unit 65 is provided on the end face of the feeder 14 stored in the feeder storage 19 on the removal direction side, which is a position that is easily visible from the worker's side, and this status display unit 65 displays the status of the feeder 14. Therefore, the worker can easily know the status of the feeder 14 just by looking at the display on the status display unit 65 of the feeder 14 stored in the feeder storage 19. This allows the worker to easily determine by visual inspection whether the feeder 14 to be retrieved from the feeder storage 19 can be reused as is, and subsequent work can be performed efficiently.

In addition, when using a feeder transport device 76 that automatically travels between the work area where the worker works and the feeder storage 19, power is supplied to the feeder 14 loaded on the feeder transport device 76, and the status of the feeder 14 stored and held in the memory unit 41 of the feeder 14 is displayed on the status display unit 65 of the feeder 14. Therefore, the worker can easily know the status of the feeder 14 just by looking at the display on the status display unit 65 of the feeder 14 loaded on the feeder transport device 76 that has returned to the work area. This allows the worker to easily determine by visual inspection whether the feeder 14 retrieved from the feeder transport device 67 can be reused as is, and subsequent work can be performed efficiently.

Next, Example 2 will be described. However, parts that are substantially the same as those in Example 1 will be given the same reference numerals and descriptions will be omitted or simplified, and mainly differences will be described.

In the first embodiment, the memory unit 41 of the feeder 14 stores and holds information on the status of the feeder 14. In the second embodiment, the memory unit (not shown) of the production management computer 70 stores information on the status of the feeder 14 set in the feeder setting unit 51 of each component mounter 12 in association with the feeder ID.

In this embodiment 2, the production management computer 70 communicates with the control unit 20 of each component mounter 12 and the control unit 82 of the feeder storage 19 to acquire the feeder ID, which is the identification information of the feeder 14 set in each component mounter 12 and the feeder storage 19, to manage the production of the component mounting line 10, and monitors the status of the feeder 14 set in each component mounter 12 based on the information sent from the control unit 20 of each component mounter 12 during production, and stores the status information of the feeder 14 in the memory unit in association with the feeder ID.

Meanwhile, the control unit 82 of the feeder storage 19 communicates with the production management computer 70, supplies power to the feeder 14 stored in the feeder storage 19, obtains a feeder ID from the feeder 14, queries the production management computer 70 for the status of the feeder 14 corresponding to the feeder ID, and displays the status of the feeder 14 on the status display unit 65.

The feeder transport device 76 also communicates with the production management computer 70, supplies power to the feeder 14 loaded on the feeder transport device 76, acquires a feeder ID from the feeder 14, queries the production management computer 70 for the status of the feeder 14 corresponding to the feeder ID, and displays the status of the feeder 14 on the status display unit 65.

In the second embodiment described above, the same effects as those in the first embodiment can be obtained.

[Other Examples]
In the above-mentioned Example 1, a status display unit 65 was provided on the end surface of the feeder 14 on the side in the removal direction, but if the upper end surface of the feeder 14 is exposed when viewed from the worker's side when the feeder 14 is placed on the feeder storage cabinet 19 or the feeder transporting device 76, the status display unit 65 may be provided on the upper end surface of the feeder 14; in short, the status display unit 65 may be provided in a position on the feeder 14 that is easily visible from the worker's side when the feeder 14 is placed on the feeder storage cabinet 19 or the feeder transporting device 76.

The configuration of the status display unit 65 is not limited to that of the first embodiment, and the color, number, and arrangement of the light emitting elements may be changed. Alternatively, the status display unit may be configured with a digital display or the like to display the status of the feeder 14 using numbers, letters, or other characters or symbols. In this case, the relationship between the numbers, letters, or other characters or symbols and the status of the feeder 14 may be defined in advance.

In addition, in the first embodiment, the feeder storage 19 is placed upstream of the component mounting line 10, but the feeder storage 19 may be placed downstream of the component mounting line 10, or may be placed between any of the multiple component mounting machines 12 that make up the component mounting line 10.

In addition, the present invention is not limited to the above-mentioned first and second embodiments, and it goes without saying that various modifications can be made without departing from the spirit of the present invention, such as omitting the feeder conveying device 67, changing the mounting structure of the feeder 14 relative to the feeder setting section 51 of the component mounter 12, or changing the configuration of the feeder 14.
