Description

This specification discloses a component mounting line and a waste tape recovery method.

Conventionally, a component mounting machine includes a mounting machine main body that mounts components supplied from a tape feeder onto a board, and a waste tape transport device that transports waste tape after supplying the components. A component mounting line is known in which components are arranged side by side. For example, in Patent Document 1, a waste tape transport device provided in each component mounter can deliver waste tape to a waste tape transport device of an adjacent component mounter on the downstream side in the board transport direction. This is disclosed.

International Publication No. 2015/045018

As a tape feeder for supplying components to a component mounting machine, there are cases in which one that supplies components using a paper tape and one that supplies components using a plastic tape are used. In this case, the waste tape generated in the component mounting line disclosed in Patent Document 1 is conveyed in a mixed state of paper waste tape and plastic waste tape, and the waste tape is transported to the component mounting line placed at the end. They are collected in the collection box on the side of the aircraft. When disposing of waste tape, it is desirable to separate the waste tape according to its material before disposing of it, but in the component mounting line disclosed in Patent Document 1, it was difficult to separate the waste tape.

The tape feeder 20 includes a reel 23 on which a tape is wound, and components are housed at predetermined intervals in each cavity of the carrier tape. These parts are protected by a film covering the surface of the tape, and when the tape is pulled out from the reel 23, the film is peeled off at the feeder section 24 and exposed. Here, the carrier tape of such tape feeder 20 may be a paper tape or a plastic tape, depending on the type and size of the parts. In this embodiment, the tape feeder 20 using a paper carrier tape is called a first tape feeder 21, and the tape feeder 20 using a plastic carrier tape is called a second tape feeder 22.

The mounting machine main body 11 includes a substrate transport device 30, a component mounting device 40, and a tape cutting mechanism 25.

As shown in FIG. 2, the substrate transfer device 30 is configured as a dual-lane transfer device with two substrate transfer paths, and is placed on a support stand 18 provided in the middle part of the main body frame 14. has been done. The substrate transport device 30 includes a conveyor belt device 33 and a backup device (not shown). The conveyor belt device 33 is provided in each substrate conveyance path, and is driven to convey the substrate S from left to right (substrate conveyance direction) in FIGS. 1 and 2. The backup device backs up the transported substrate S.

The component mounting device 40 is a device that mounts components onto the board S backed up by the backup device. The component mounting device 40 is housed within the main body frame 14. As shown in FIG. 2, the component mounting device 40 includes a guide rail 42 provided along the Y-axis direction in the upper part of the main body frame 14, and a Y-axis slider 44 that is movable along the guide rail 42.

It also includes a parts camera 56 for photographing images, and a nozzle stocker 58 for stocking a plurality of types of suction nozzles 52 that can be attached to the head 50.

The tape cutting mechanism 25 is a mechanism for cutting the tape (waste tape) after parts have been supplied and sending it downward. The tape cutting mechanism 25 includes a tape cutter 26, a tape duct 27, and a tape chute 28. The tape cutter 26 is for cutting waste tape. A tape cutter 26 is provided between a tape duct 27 and a tape chute 28. The tape duct 27 and tape chute 28 are for sending waste tape downward. The tape duct 27 and tape chute 28 are provided so as to be located behind the feeder section 24 when the tape feeder 20 is attached to the mounting machine main body 11. The waste tape that has passed through the tape duct 27 is cut into pieces by a tape cutter 26, falls through a tape chute 28, and is sent to a waste tape transport device 60.

The waste tape transport device 60 is a device that transports the waste tape sent from the tape cutting mechanism 25 out of the component mounter 10 along the board transport direction. As shown in FIG. 3A, the waste tape conveying device 60 includes a conveyor rail 62 that rotatably supports a driving wheel 61a and a driven wheel 61b, and a conveyor belt 64 that spans the driving wheel 61a and the driven wheel 61b. It is configured as a belt conveyor device comprising: In this waste tape conveying device 60, a drive motor 66 is attached to the rotating shaft of a drive wheel 61a. The drive motor 66 is a motor that can rotate in forward and reverse directions. When the drive motor 66 is rotated in the forward direction, the conveyor belt 64 is rotated to convey the waste tape upstream (from right to left) in the substrate conveyance direction. On the other hand, by rotating the drive motor 66 in the opposite direction, the conveyor belt 64 is rotationally driven to convey the waste tape downstream (from right to left) in the substrate conveyance direction.

The conveyor rail 62 and the drive motor 66 are fixed to the base 12 via a support member 69 (see FIG. 2). Although not shown, the support member 69 is provided with an inclination angle adjustment mechanism that can adjust the inclination angle with respect to the base 12, and the inclination angle of the waste tape can be adjusted within a predetermined range (for example, from +30 degrees with 0 degrees being horizontal). (within a range of -30 degrees) (see Figures 3(b) to 3(e)).

The conveyor rail 62 is configured so that its entire length can be expanded and contracted by a gas spring 68. When the gas spring 68 is contracted, it fits within the width of the pedestal 12 in the X-axis direction (substrate conveyance direction), and the gas spring 68 In the extended state, a portion thereof protrudes from the pedestal 12. Although not shown, the frame of the conveyor is provided with a locking mechanism for keeping the gas spring 68 in a contracted state.

When the conveyor rail 62 is contracted, the conveyor belt 64 is in a loosened state (see FIGS. 3(a) to (c)), and when the conveyor rail 62 is extended, the conveyor belt 64 is at a tension suitable for driving the belt. The length of the belt is adjusted so that it is in a tensioned state (see FIGS. 3(d) and (e)).

Here, consider a case where a component mounting line L is configured by installing a plurality of component mounting machines 10A to 10F. As shown in FIG. 4, when a plurality of component mounters 10 are installed side by side in the board transport direction, the waste tape transport devices 60 of each component mounter 10 are aligned in a line in the board transport direction. The inclination angle of the waste tape conveying device 60 (belt conveyor device) of the component mounting machines 10A and 10B is adjusted so that it slopes upward to the left, and by protruding a part from the pedestal 12 in the direction of conveying the waste tape. , and vertically overlap the waste tape conveying device 60 (belt conveyor device) of the adjacent component mounting machine 10. On the other hand, the inclination angle of the waste tape conveying device 60 (belt conveyor device) of the component mounting machines 10C to 10F is adjusted so that it slopes upward to the right, and a part of it protrudes from the pedestal 12 in the direction of conveying the waste tape. This vertically overlaps the waste tape conveying device 60 (belt conveyor device) of the adjacent component mounting machine 10. By doing so, the waste tape can be transferred smoothly from the waste tape transport device 60 to the adjacent waste tape transport device 60, and the waste tape can be prevented from falling during the transfer. Thereby, each waste tape transport device 60 can transport the waste tape to the end of the component mounting line L while delivering the waste tape to the waste tape transport device 60 of the adjacent component mounting machine 10. Furthermore, if the component mounting machines 10A and 10B that are continuous from the most upstream part of the component mounting line L are set as a first component mounter group G1, and the remaining component mounters 10C to 10F are set as a second component mounter group G2, The waste tape transport device 60 of the first component mounter group G1 transports the waste tape to the upstream side in the board transport direction, and the waste tape transport device 60 of the second component mounter group G2 transports the waste tape to the downstream side in the board transport direction. It can also be transported to

The control device 70 is configured as a microprocessor centered on a CPU, and controls the entire component mounting machine 10. The control device 70 outputs control signals to the mounting machine main body 11, the tape feeder 20, and the waste tape conveyance device 60. Further, the control device 70 is communicably connected to the tape feeder 20, the control devices 70 of other component mounting machines 10, the management device 80, and the like.

The management device 80 is a computer equipped with a CPU 81, a ROM 82, a RAM 83, a storage 84, etc., and is communicably connected to the control device 70 of the component mounting machine 10.

The collection box 90 is a box-shaped member that collects waste tape that has been transported to the start or end of the component mounting line L by the waste tape transport device 60.

Next, the component mounting process of the component mounting line L configured in this way will be explained. In the component mounting process, first, the control device 70 controls the board transport device 30 until the board S comes directly above the backup device. Next, the control device 70 controls the backup device so that the substrate S is backed up when the substrate S comes directly above the backup device. Next, the control device 70 controls the tape feeder 20 so that the tape is fed out from the reel 23 and parts are supplied. Then, the control device 70 controls the X-axis slider 48 and the Y-axis slider 44 so that the suction nozzle 52 is positioned directly above the supplied component. Next, the control device 70 causes the suction nozzle 52 to suction the component by lowering the suction nozzle 52 and applying negative pressure to the suction port of the suction nozzle 52 . After sucking the component in this way, the control device 70 raises the suction nozzle 52 and controls each slider 44, 48 so that the component sucked by the suction nozzle 52 comes directly above the mounting position of the board S. Then, the control device 70 releases the suction of the component by the suction nozzle 52 by lowering the suction nozzle 52 until the component is pressed against the mounting position of the board S and applying positive pressure to the suction port of the suction nozzle 52. do. Each component is mounted on the substrate S by repeating these operations. After all the components that should be mounted on the board S by the machine itself have been mounted, the control device 70 controls the backup device so that the backup of the board S is canceled and the board S is transported to the downstream side. The substrate transport device 30 is controlled as follows.

Here, tape feeders 20 with the same tape material are set in each mounter main body 11 of the first component mounter group G1, and tape feeders 20 with the same tape material are set in each mounter main body 11 of the second component mounter group G2. The same tape feeder 20 can be set. For example, as shown in FIG. 7, the first tape feeder 21 can be set in the first component mounter group G1, and the second tape feeder 22 can be set in the second component mounter group G2. In this case, in the waste tape transport device 60 of the first component mounter group G1, the rotation direction of the drive motor 66 is set in the forward direction so that the conveyor belt 64 transports the waste tape upstream in the board transport direction. The rotation direction of the drive motor 66 is set in the opposite direction so that the conveyor belt 64 of the waste tape transport device 60 of the two component mounting machine group G2 transports the waste tape downstream in the board transport direction. In this way, the paper waste tape from the first tape feeder 21 and the plastic waste tape from the second tape feeder 22 are separated and collected in the collection boxes 90 arranged on the sides of the starting and ending ends of the component mounting line L. Ru.

Further, each mounter body 11 of the first component mounter group G1 is set with tape feeders 20 having different tape materials, and each mounter body 11 of the second component mounter group G2 is set with the following tape feeders 20 having different tape materials. Tape feeders 20 whose tapes are made of the same material can be set. For example, as shown in FIG. 8, the first tape feeder 21 and the second tape feeder 22 are set so as to coexist in the mounter main body 11 of the first component mounter group G1, and at the same time, the The second tape feeder 22 can be set in the mounting machine main body 11. In this case, in the waste tape transport device 60 of the first component mounting machine group G1, the rotation direction of the drive motor 66 is set in the forward direction so that the conveyor belt 64 transports the waste tape upstream in the board transport direction, The rotation direction of the drive motor 66 is set in the opposite direction so that the conveyor belt 64 of the waste tape transport device 60 of the second component mounter group G2 transports the waste tape downstream in the board transport direction. In this way, the paper waste tape and the waste tape containing a mixture of paper waste tape and plastic waste tape are transported in opposite directions. Therefore, compared to the case where the tape feeder 20 is set in the mounting machine main body 11 or the transport direction of the waste tape transport device 60 is determined without considering the material of the waste tape, it becomes easier to separate the waste tape. .

Next, in executing the above-described component mounting process, the boundaries between the first component mounter group G1 and the second component mounter group G2 are determined, and the boundaries between the first component mounter group G1 and the second component mounter group G2 are determined. A waste tape conveyance direction determining routine for determining the waste tape conveyance direction will be described with reference to FIGS. 6 to 9. FIG. 6 is a flowchart showing an example of a waste tape transport direction determination routine. 7 to 9 are explanatory diagrams showing a state in which the tape feeder 20 is set in each mounting machine main body 11. This routine is stored in the storage 84 of the management device 80 and executed by the CPU 81. Note that this process is performed on the component mounting line L before the above-described component mounting process is executed.

When this routine is started, the CPU 81 first reads information regarding the tape feeder 20 used for producing the substrate S from the storage 84, and also divides the tape feeder 20 into the first tape feeder 21 and the second tape feeder 22 for each tape material. (S100). This information regarding the tape feeder 20 includes information regarding the material that makes up the tape in the tape feeder 20 and information regarding restrictions on the placement position of the tape feeder 20.

Next, the CPU 81 determines whether there is a tape feeder 20 whose placement position is restricted (S110). The tape feeder 20 with restrictions on the placement position (hereinafter referred to as the tape feeder 20 with restrictions on the placement position) is a tape feeder 20 that supplies components to be mounted on the board S before the components supplied from the first tape feeder 21. The first tape feeder 21 supplies components to be mounted on the substrate S before the components supplied from the second tape feeder 22 and the second tape feeder 22. Examples of the tape feeder 20 with placement position restrictions include a tape feeder 20 that feeds parts that are shorter than other adjacent parts among the parts used to produce the board S, and a tape feeder 20 that feeds parts that are shorter than other adjacent parts among the parts used to produce the board S, and a tape feeder 20 that feeds parts that are shorter than other adjacent parts among parts used to produce the board S, and These include a tape feeder 20 that supplies components to be mounted on S, a tape feeder 20 that supplies shield components, and the like. A shield component is a component mounted on the board S so as to cover other components mounted on the board S from above. In this embodiment, the tape feeder 20 with placement position restrictions is installed later than the second tape feeder 22 that must be set in the mounter main body 11 of the component mounter 10A and the components fed from the second tape feeder 22. It is assumed that the first tape feeder 21 supplies components to be mounted on the substrate S. Therefore, the CPU 81 determines whether there is a second tape feeder 22 that needs to be set in the mounter main body 11 of the component mounter 10A.

If a negative determination is made in S110, the CPU 81 determines the first component mounter group G1 and the second component mounter group G2 according to the ratio of the first tape feeder 21 (S120). This process is executed as follows. That is, the CPU 81 obtains the number of first tape feeders 21 and the number of second tape feeders 22. Next, the CPU 81 derives the ratio of the first tape feeder 21. The ratio of the first tape feeder 21 is the ratio of the first tape feeder 21 to all tape feeders 20. Next, the CPU 81 determines the number of component mounters 10 that belong to the first component mounter group G1 (when determining the first component mounter group G1, the number of component mounters 10 that belong to the first component mounter group G1 and are arranged consecutively) (number of different component mounting machines 10) is derived. Specifically, the integrated value is derived by multiplying the number of component mounting machines 10 constituting the component mounting line L by the ratio of the first tape feeders 21. If the integrated value is an integer, the CPU 81 uses the integrated value as a constituent number. On the other hand, if the integrated value is a decimal, the CPU 81 executes the following rounding process. If there are more first tape feeders 21 than second tape feeders 22, the CPU 81 rounds up the integrated value and sets the value obtained as the number of components. If there are fewer first tape feeders 21 than second tape feeders 22, the CPU 81 rounds down the integrated value to the number of configurations. Then, the CPU 81 determines, as the first component mounter group G1, the component mounters 10 that are consecutively lined up by the number of components starting from the component mounter 10A located at the most upstream position, and also determines the component mounters 10 that are consecutively lined up in the first component mounter group G1. 10 is determined as the second component mounting machine group G2.

Subsequently, the CPU 81 determines to set the first tape feeder 21 in the first component mounter group G1 and to set the second tape feeder 22 in the second component mounter group G2 (S130).

Here, an example of a state in which the first component mounter group G1 and the second component mounter group G2 are determined according to S120 and S130, and the first tape feeder 21 and the second tape feeder 22 are set in the mounter main body 11. will be explained using FIG. In FIG. 7, the number ratio of the first tape feeder 21 and the second tape feeder 22 is 2:3. In this case, the ratio of the first tape feeder 21 is 0.4. Moreover, in FIG. 7, since the component mounting line L has six component mounting machines 10, the integrated value is 2.4. Then, 2, which is obtained by rounding down 2.4, becomes the configuration number. Therefore, the two component mounters 10 (component mounters 10A, 10B) that are lined up consecutively including the component mounter 10A become the first component mounter group G1, and the other component mounters 10 (component mounters 10C) ~10F) becomes the second component mounting machine group G2.

On the other hand, if an affirmative determination is made in S110, the CPU 81 determines to set the tape feeder 20 with placement position restrictions in the mounting machine main body 11 of the component mounting machine 10A (S140).

Next, the CPU 81 determines the first component mounter group G1 and the second component mounter group G2 according to the adjusted ratio of the first tape feeder 21 and the second tape feeder 22 (S150). . To adjust the ratio, when the second tape feeder 22 is placed upstream of the first tape feeder 21 in the substrate transport direction due to placement position restrictions, the number of first tape feeders 21 is added by that number, and the second tape feeder 22 is This is done by subtracting the number of tape feeders 22 and recalculating the ratio. In S150, the CPU 81 performs the same process as S120 except that the adjusted ratio is used instead of the ratio of the first tape feeder 21.

Then, the CPU 81 sets the first tape feeder 21 in one of the component mounters 10 belonging to the first component mounter group G1 other than the component mounter 10A, and sets the second tape feeder 21 in the second component mounter group G2. (S160).

An example of a state in which the first component mounter group G1 and the second component mounter group G2 are determined according to S140 to S160 and the first tape feeder 21 and second tape feeder 22 are set in the mounter main body 11 is shown in FIG. This will be explained using 8. In FIG. 8, some of the second tape feeders 22 are arranged upstream of the first tape feeders 21 in the substrate transport direction due to restrictions on the arrangement positions, so the number of first tape feeders 21 and the number of second tape feeders 22 The ratio with the number of is adjusted, and the adjusted ratio is 0.5. Furthermore, in FIG. 8, the component mounting line L has six component mounting machines 10, so the integrated value is three. Since there is no need to perform rounding processing, the number of configurations is 3. Therefore, the three component mounters 10 (10A to 10C) that are lined up consecutively including the component mounter 10A become the first component mounter group G1, and the other component mounters 10 (10D to 10F) are the second component mounter group G1. This becomes component mounting machine group G2.

In addition, in FIG. 8, in the first component mounter group G1, the mounter body 11 in which the first tape feeder 21 is set (the mounter body 11 of the component mounters 10B and 10C) and the second tape feeder 22 are set. The mounter main body 11 (the mounter main body 11 of the component mounter 10A) is mixed. However, as shown in FIG. 9, in the first component mounter group G1, the first tape feeder 21 and the second tape feeder 22 are mixed in one mounter body 11 (the mounter body 11 of the component mounter 10A). It may be set as follows.

After S130 or S160, the CPU 81 determines the waste tape conveyance direction in the first component mounting machine group G1 to be upstream in the board conveyance direction (leftward white arrow in FIGS. 7 to 9) (S170), and The waste tape transport direction in the mounting machine group G2 is determined to be the downstream side of the board transport direction (rightward white arrow in FIGS. 7 to 9) (S180).

Next, the CPU 81 instructs the operator to set the tape feeder 20 (S190). Specifically, the CPU 81 causes a display device (not shown) provided in the management device 80 to display information regarding the tape feeder 20 necessary for producing the substrate S and information regarding the setting position where the tape feeder 20 is to be set. After confirming this information, the operator prepares the tape feeders 20 necessary for producing the substrates S, and sets the tape feeders 20 at the instructed setting positions. Note that the tape feeder 20 may be automatically set using an automatic exchange device (not shown).

Then, the CPU 81 instructs the control device 70 of each component mounting machine 10 regarding the waste tape transport direction (S200). When the control device 70 of each component mounter 10 receives an instruction for the waste tape conveyance direction, it sets the rotation direction of the drive motor 66 and controls the tilt angle adjustment mechanism so that the waste tape conveyance direction is the instructed direction. to adjust the inclination direction and inclination angle of the waste tape conveying device 60. After S200, the CPU 81 ends this routine.

Here, the correspondence between the main elements of the embodiment and the main elements of the present disclosure will be explained. That is, the component mounting line L corresponds to the component mounting line, the first tape feeder 21 corresponds to the first tape feeder, the second tape feeder 22 corresponds to the second tape feeder, and the mounting machine main body 11 corresponds to the mounting machine main body. , the component mounters 10A to 10F correspond to a plurality of component mounters, the first component mounter group G1 corresponds to the first component mounter group, and the second component mounter group G2 corresponds to the second component mounter group. It corresponds to a group of aircraft.

In the component mounting line L described above, only paper waste tape is transported to the upstream side in the board transport direction. Therefore, it becomes easier to separate the waste tape compared to the case where the tape feeder 20 is set in the mounting machine main body 11 or the transport direction of the waste tape transport device 60 is determined without considering the material of the waste tape.

Further, in the component mounting line L, a second tape feeder 22 may be set in the mounting machine main body 11 of the second component mounting machine group G2. In this way, paper waste tape and plastic waste tape can be separated.
