Description

The present invention relates to a tape feeder used as a component supply unit of a component mounting device for mounting components on a substrate.

The tape feeder, which is known as the parts supply unit of the parts mounting device that mounts the parts picked up by the mounting head on the board, is a tape composed by covering the base tape in which the parts are stored in the pocket for storing the parts with the top tape. The member is conveyed, the top tape is peeled off at a predetermined peeling position, and the component is supplied to the component supply position. The tape feeder conveys the tape member by rotating the sprocket by engaging the outer peripheral teeth of the sprocket with the frame having the tape passage which is the passage of the tape member to be conveyed and the feed hole of the tape member in the tape passage. It is equipped with a tape carrier.

In front of the tape feeder (downstream side in the transport direction of the tape member), a horizontal upper wall portion and left and right side wall portions extending downward from the left and right ends of the upper wall portion are provided, and the frame is opened downward to form a frame. A cover member having a channel type (groove shape) extending in the front-rear direction is attached. The tape passage of the tape feeder is an area exposed at the upper part of the frame (frame upper surface area) at the front portion of the frame, and the cover member covers at least a part of the frame upper surface area. When the cover member covers a part of the frame upper surface region from above, the upper wall portion of the cover member is located above the frame upper surface region (see, for example, Patent Document 1 below).

By the way, the size of parts supplied from the tape member used for the tape feeder has been minimized in recent years. As the component size is minimized, the posture of the component housed in the pocket of the tape member transported in the upper surface area of the frame is easily affected by the processing accuracy of the lower surface of the upper wall portion of the cover member, and the component is supplied. Pick-up mistakes of parts stored in the pockets located at the positions are likely to occur. Such disturbance of the posture of the parts stored in the pockets of the tape member is suppressed by performing a high degree of processing to increase the parallelism of the lower surface of the upper wall portion of the cover member with respect to the upper surface region of the frame at the time of manufacturing the cover member. be able to.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a component mounting device 1 according to an embodiment of the present invention. The component mounting device 1 is a device that repeatedly executes the component mounting work of mounting the component BH on the board KB carried in from the upstream process side and carrying it out to the downstream process side. Here, for convenience of explanation, the transport direction of the board KB in the component mounting device 1 (the left-right direction seen from the worker OP) is set to the X-axis direction, and the horizontal direction orthogonal to the X-axis direction (the front-back direction seen from the worker OP). Is the Y-axis direction. Further, the vertical direction is the Z-axis direction.

In FIG. 1, the component mounting device 1 includes a base 11, a board transfer conveyor 12, a tape feeder 13, a mounting head 14, a head moving mechanism 15, a board camera 16, a component camera 17, and a control device 18. The base 11 is installed on the floor surface FL, and the substrate transfer conveyor 12 is provided so as to extend on the base 11 in the X-axis direction. The substrate transfer conveyor 12 carries in the substrate KB sent from the upstream process side, and then positions the substrate KB at a predetermined working position.

In FIG. 1, a feeder carriage DS is connected to an end portion on the front side (worker OP side) of the base 11. A feeder base FB is provided on the upper part of the feeder carriage DS, and the tape feeder 13 is detachably attached to the feeder base FB (see also FIG. 2). A plurality of tape feeders 13 can be attached to the feeder base FB side by side in the X-axis direction. When the feeder carriage DS is connected to the base 11, a plurality of tape feeders 13 attached to the feeder base FB are collectively connected to the base 11.

In FIG. 1, the feeder carriage DS holds a reel RL around which the carrier tape 20 is wound. A reel RL is prepared for each tape feeder 13, and a carrier tape 20 drawn from the reel RL is attached to the corresponding tape feeder 13. The tape feeder 13 conveys the attached carrier tape 20 forward (toward the substrate transfer conveyor 12), and supplies the component BH to a predetermined component supply position 13K (see also FIGS. 2 and 3).

In FIGS. 4 and 5 (a) and 5 (b) (FIGS. 5 (a) and 5 (b) are enlarged views of the region AR in FIG. 4), the carrier tape 20 has a base tape 21 and a top tape 22. It is configured. The base tape 21 is provided with pockets 23 for storing a large number of parts opened upward in a row in the longitudinal direction of the base tape 21 at equal intervals. One component BH is stored in each pocket 23. The top tape 22 is attached to the upper surface of the base tape 21 to prevent the component BH from falling out of the pocket 23. A plurality of feed holes 24 are provided in a row at equal intervals at positions parallel to the row of pockets 23 of the base tape 21.

Here, FIG. 5A shows a flat type carrier tape 20 in which the entire base tape 21 is flat, and FIG. 5B shows an embossed portion 21E in which the base tape 21 projects downward. The embossed type carrier tape 20 which has is shown. Any type of carrier tape 20 may be used, but in the present embodiment, the flat type carrier tape 20 is used.

In FIG. 1, the mounting head 14 includes a plurality of nozzles 14N extending downward. Each nozzle 14N can move up and down with respect to the mounting head 14 and rotate around the Z axis. The mounting head 14 picks up the component BH supplied by the tape feeder 13 to the component supply position 13K by attracting the component BH to the lower end of each nozzle 14N. The head moving mechanism 15 is composed of, for example, an XY moving mechanism, and moves the mounting head 14 in the horizontal direction and in the vertical direction.

In FIG. 1, the substrate camera 16 is attached to the mounting head 14. The substrate camera 16 has an imaging optical axis directed downward, and by moving together with the mounting head 14, the substrate camera 16 images the substrate KB positioned at the working position by the substrate transfer conveyor 12.

In FIG. 1, the component camera 17 is provided in the area between the substrate transfer conveyor 12 and the tape feeder 13 on the base 11. The component camera 17 has an imaging optical axis directed upward, and when the mounting head 14 having the component BH adsorbed on each of the plurality of nozzles 14N moves so as to pass through the upper region of the component camera 17 in the X-axis direction, each The component BH is imaged from below.

The control device 18 stores various data in addition to the component mounting program. The control device 18 executes the component mounting operation for mounting the component BH on the board KB by operating each part of the component mounting device 1 according to the component mounting program.

In the component mounting work, the board transfer conveyor 12 first operates, receives the board KB sent from the upstream process side, and positions it at the work position. When the board KB is positioned at the working position, the head moving mechanism 15 moves the mounting head 14 above the board KB. As a result, the substrate camera 16 images the substrate KB, and the control device 18 recognizes the substrate KB based on the image captured by the substrate camera 16.

When the control device 18 recognizes the board KB, the mounting head 14 repeatedly executes the mounting turn. The mounting head 14 picks up the component BH supplied by the tape feeder 13 in one mounting turn, and moves so as to pass above the component camera 17 in the X-axis direction to cause the component camera 17 to image the component BH. , The operation of mounting the component BH at the component mounting position defined on the board KB is performed in this order.

The control device 18 performs component recognition based on an image obtained by imaging the component BH by the component camera 17. When the component BH is mounted on the board KB, the mounting head 14 corrects the position of the component BH with respect to the board KB based on the result of the component recognition performed by the control device 18.

When all the component BHs to be mounted on the board KB are mounted by repeatedly executing the above mounting pattern, the board transfer conveyor 12 carries out the board KB to the downstream process side. This completes the component mounting work for each board KB.

In the component mounting device 1 having such a configuration, the configuration of the tape feeder 13 is characteristic in one embodiment, and the description thereof will be described below.

In FIG. 2, the tape feeder 13 includes a frame 31, a cover member 32, a tape transport section 33, and a top tape recovery section 34. The frame 31 has a box shape that extends in the YZ plane as a whole. A protrusion (not shown) protruding downward is formed on the lower surface of the frame 31, and the tape feeder 13 is attached to the feeder base FB by engaging this protrusion with the slot SL provided in the feeder base FB. Can be done.

In FIG. 2, the frame 31 is formed with a tape passage 31L, which is a passage for the carrier tape 20 to be conveyed. The tape passage 31L is formed in a groove shape that opens on one side surface of the frame 31 (here, the right side surface as seen from the operator OP).

In FIG. 2, the tape passage 31L extends in a substantially horizontal direction forward from the rear end portion (end portion on the worker OP side) of the frame 31, and then rises in the front diagonal direction near the center in the front-rear direction of the frame 31. Is extending. The front end portion thereof is exposed on the upper surface of the frame 31. The upper surface of the front portion of the frame 31 is a region where a part of the tape passage 31L is exposed on the upper part of the frame 31. Hereinafter, this region is referred to as “frame upper surface region 31R” (FIG. 6).

In FIGS. 2 and 3, the cover member 32 is provided on the front upper portion of the frame 31 so as to cover at least a part of the frame upper surface region 31R from above. As shown in FIGS. 3, 6 and 7, the cover member 32 includes a horizontal upper wall portion 32a and left and right side wall portions 32b extending downward from both left and right ends of the upper wall portion 32a, and lower. It has a channel-type (groove shape) shape that is open to the front and extends in the front-rear direction (Y-axis direction) of the frame 31.

In FIGS. 6, 7 and 8, the cover member 32 is provided with a component outlet 32G for taking out the component BH from the pocket 23 of the carrier tape 20 located at the component supply position 13K. As shown in FIGS. 3 and 6, the front end of the cover member 32 is pivotally connected to the upper part of the frame 31 on the front end side by the pivot pin 32P. The cover member 32 can be slightly swung in the direction of raising the rear end side with respect to the frame upper surface region 31R with the pivot pin 32P as a fulcrum.

As shown in FIG. 6, a shaft member 32F extending in the X-axis direction is attached to the front end portion of the cover member 32. The shaft member 32F is urged toward the frame 31 side by a spring member 32S interposed between the shaft member 32F and the front end portion of the frame 31. Therefore, the carrier tape 20 on the frame upper surface region 31R advances forward while bringing the upper surface into contact with the lower surface of the cover member 32.

In FIGS. 3 and 9 (FIG. 9 is a cross-sectional view taken along the line V1-V1 in FIG. 8), the upper wall portion 32a of the cover member 32 is in a state where the cover member 32 covers a part of the frame upper surface region 31R from above. The lower surface 32K of the frame is located above the frame upper surface region 31R. Further, the left and right side wall portions 32b are located outside the left and right side surfaces of the frame 31.

In FIGS. 9 and 10 (FIG. 10 is a cross-sectional view taken along the line V2-V2 in FIG. 8), the thickness of the carrier tape 20 is between the lower surface 32K of the upper wall portion 32a of the cover member 32 and the frame upper surface region 31R. A gap CL substantially the same as is formed. The space in which the gap CL is formed constitutes a part of the tape passage 31L, and the carrier tape 20 passing through this space is prevented from rising from the frame upper surface region 31R by the cover member 32.

When attaching the carrier tape 20 to the frame 31, the operator OP first inserts the leading portion of the carrier tape 20 into the space between the frame upper surface region 31R and the cover member 32 from the rear of the cover member 32. Then, a portion rearward from the inserted portion is inserted into the tape passage 31L formed in the frame 31 from the opening side (right side of the frame 31).

Here, when the leading portion of the carrier tape 20 is inserted into the space between the frame upper surface region 31R and the cover member 32, the rear end side of the cover member 32 is floated with respect to the frame upper surface region 31R. As a result, the gap CL at the rear portion of the cover member 32 can be temporarily increased, and the operator OP can easily insert the tip end portion of the carrier tape 20 into the space between the frame upper surface region 31R and the cover member 32.

In FIG. 2, the tape transport portion 33 includes a sprocket 33A provided on the frame 31, a drive motor 33B, and a transmission gear portion 33C. The sprocket 33A is rotatably attached to the upper part of the frame 31 on the front end side around the X axis. Of the outer peripheral teeth 33G (FIG. 3) of the sprocket 33A, those located directly above the center of rotation of the sprocket 33A (referred to as the uppermost outer peripheral teeth 33G) project upward from the frame upper surface region 31R (FIG. 6). And FIG. 9).

When the drive motor 33B is operated and the sprocket 33A is rotated via the transmission gear portion 33C (arrow A shown in FIGS. 2 and 3), the uppermost outer peripheral teeth 33G of the sprocket 33A move forward. The uppermost outer peripheral teeth 33G of the sprocket 33A are engaged with the feed hole 24 of the carrier tape 20 inserted between the frame upper surface region 31R and the cover member 32 (FIG. 9), and the sprocket 33A is rotationally driven. When the uppermost outer peripheral tooth 33G is moved forward, the entire carrier tape 20 is pulled forward. As a result, the carrier tape 20 is conveyed forward in the tape passage 31L (arrow B shown in FIGS. 2 and 3).

As described above, in the present embodiment, the tape transport portion 33 engages the outermost peripheral teeth 33G of the uppermost portion of the sprocket 33A with the feed hole 24 of the carrier tape 20 located in the region of the tape passage 31L covered by the cover member 32. The carrier tape 20 is conveyed by rotating the sprocket 33A.

In FIGS. 3, 6, 7, and 8, a portion of the cover member 32 located directly above the center of rotation of the sprocket 33A is provided with a relief opening 32M extending in the front-rear direction (Y-axis direction) of the frame. The uppermost outer peripheral tooth 33G of the sprocket 33A passes through the escape opening 32M (FIG. 9). Therefore, the sprocket 33A can rotate the outer peripheral teeth 33G without interfering with the cover member 32.

In FIG. 2, the top tape collecting portion 34 is provided at a position closer to the rear of the upper portion of the frame 31, and has a pair of feed rollers 34a and a tension applying portion 34b. As shown in FIG. 11, the top tape 22 of the carrier tape 20 is formed from the base tape 21 with the trailing edge (edge on the worker OP side) of the component outlet 32G of the cover member 32 as the peeling position 32H (see also FIG. 7). It is peeled off, folded back (see also FIGS. 2 and 3), and sandwiched between a pair of feed rollers 34a. An appropriate tension is applied to the top tape 22 between the peeling position 32H and the feed roller 34a by the tension applying portion 34b.

When the sprocket 33A rotates and the carrier tape 20 is conveyed forward, the pair of feed rollers 34a rotate in synchronization with the rotation of the sprocket 33A. As a result, the top tape 22 is pulled backward by the pair of feed rollers 34a (arrow C shown in FIGS. 2 and 3), and is fed into the top tape accommodating space 31K (FIG. 2) formed at the rear of the frame. It will be recovered.

The carrier tape 20 in the tape passage 31L is conveyed forward by the rotation of the sprocket 33A, so that each pocket 23 formed in the base tape 21 is located immediately in front of the peeling position 32H. 13K) will be reached in sequence. Since the top tape 22 has already been peeled off when the pocket 23 reaches the component supply position 13K, the mounting head 14 can pick up the component BH (from the component outlet 32G) at the component supply position 13K. (Fig. 11). The carrier tape 20 (base tape 21) that has passed through the cover member 32 is discharged to the outside from the front end of the frame 31 (FIG. 3).

Here, as shown in FIGS. 7, 8 and 12 (a) and 12 (b), a plurality of tape holding portions 41 are provided on the upper wall portion 32a of the cover member 32. As shown in FIGS. 11 and 13 (FIG. 13 is an enlarged view of the region RY in FIG. 10), the plurality of tape holding portions 41 are located below the lower surface 32K of the upper wall portion 32a of the cover member 32, respectively. It has a pressing surface 41K. Each tape pressing portion 41 presses the vicinity of the pocket 23 located at the component supply position 13K from above among the base tape 21 from which the top tape 22 has been peeled at the peeling position 32H by the pressing surface 41K (in the frame upper surface region 31R). It has a function of pressing).

In the present embodiment, as shown in FIGS. 7, 8 and 12 (a) and 12 (b), the tape holding portion 41 faces the cover member 32 in the width direction (X-axis direction) of the carrier tape 20. It is provided in each of the two areas. Specifically, among the regions along the edge of the component outlet 32G of the cover member 32, 1 is included in the region on one side (left side when viewed from the operator OP) of the pocket 23 located at the component supply position 13K. One tape holding portion 41 (referred to as “left side tape holding portion 41a”) is provided, and two are provided in the area on the other side (right side when viewed from the operator OP) of the pocket 23 located at the component supply position 13K. A tape holding portion 41 (referred to as “right side tape holding portion 41b”) is provided.

14 (a) is a cross-sectional view taken along the line V3-V3 in FIG. 8, and FIG. 14 (b) is a cross-sectional view taken along the line V4-V4 taken along the line in FIG. As shown in FIG. 14A, the left side tape holding portion 41a is provided so as to extend the position on the left side of the pocket 23 located at the component supply position 13K along the transport direction (Y-axis direction) of the carrier tape 20. As shown in FIG. 14B, the right side tape holding portion 41b is provided at a position where the pocket 23 located at the component supply position 13K is sandwiched from the front-rear direction in the transport direction of the carrier tape 20.

In FIGS. 14A and 14B, cover members are attached to both ends of the carrier tape 20 on the lower surface side of each of the left side tape holding portion 41a and the two right side tape holding portions 41b in the flow direction (Y-axis direction). An induction surface 41Y having a shape that does not hinder the progress of the carrier tape 20 (base tape 21) that passes through the lower surface side of the 32 is formed. Although the guide surface 41Y is a tapered surface 41T here, it may be a curved surface 41R having a rounded shape as shown in FIGS. 15A and 15B. By forming the guide surface 41Y having a shape that does not hinder the progress of the carrier tape 20 on the lower surface of the tape holding portion 41 in this way, the carrier tape 20 passing through the lower surface side of the cover member 32 can smoothly move to the frame upper surface region 31R. Can proceed.

When the carrier tape 20 passing through the space between the frame upper surface region 31R and the cover member 32 passes through the component supply position 13K (component outlet 32G), the top tape 22 is peeled off at the peeling position 32H. Then, when the upper surface of the carrier tape 20 (base tape 21) from which the top tape 22 has been peeled off passes through the component supply position 13K, it is pressed from above against the frame upper surface region 31R by the plurality of tape holding portions 41 (FIG. 11). And FIGS. 12 (a) and 12 (b)).

As described above, the shaft member 32F provided at the front end portion of the cover member 32 is urged toward the frame 31 side by the spring member 32S, and therefore the carrier tape 20 on the frame upper surface region 31R covers the upper surface thereof. It advances forward while being in contact with the lower surface of the member 32. Therefore, if the size of the component BH in each pocket 23 is small, the component BH may be affected by the processing accuracy of the lower surface of the cover member 32 and may run wild in the pocket 23. However, in the present embodiment, the component BH may run wild in the pocket 23. Since the upper surface of the carrier tape 20 passing through the component supply position 13K is pressed from above by the plurality of tape holding portions 41, even if the carrier tape 20 is affected by the processing accuracy of the lower surface of the cover member 32 and flutters, the component In the vicinity of the pocket 23 passing through the supply position 13K, the carrier tape 20 is not affected by the fluttering, and the rampage of the component BH in the pocket 23 is suppressed. Therefore, the component BH in the pocket 23 in which the top tape 22 is peeled off and is open upward is supplied to the component supply position 13K in a stable state, and the occurrence of a pickup error of the component BH by the mounting head 14 is suppressed. Will be done.

16 (a) and 16 (b) show a first modification of the tape holding portion 41. The tape retainer 41 in the first modification is provided with two tape retainers 41 in each of the two regions of the carrier tape 20 facing each other in the width direction. Specifically, among the regions along the edge of the component outlet 32G of the cover member 32, the region on one side of the pocket 23 (left side when viewed from the operator OP) located at the component supply position 13K and the component. Two tape holding portions 41 are provided in each of the area on the other side (right side when viewed from the operator OP) of the pocket 23 located at the supply position 13K. The two tape holding portions 41 provided in these left and right regions are arranged at positions where the pocket 23 located at the component supply position 13K is sandwiched from the front-rear direction of the carrier tape 20 in the transport direction. Even with such a configuration, the periphery of the pocket 23 located at the component supply position 13K is pressed against the frame upper surface region 31R by the tape holding portion 41, so that the occurrence of pickup mistakes due to the fluttering of the carrier tape 20 can be reduced. Can be done.

17 (a) and 17 (b) show a second modification of the tape holding portion 41, and FIGS. 18 (a) and 18 (b) show a third modification of the tape holding portion 41. .. The tape retainer 41 in the second modification has a ring shape having a circular component outlet 32G in the center, and is located at the component supply position 13K of the base tape 21 from which the top tape 22 has been peeled off. The entire area surrounding the pocket 23 is pressed against the frame upper surface area 31R by the ring-shaped pressing surface 41K. Further, the tape retainer 41 in the third modification has a rectangular frame shape having a rectangular component outlet 32G in the center, and is located at the component supply position 13K of the base tape 21 from which the top tape 22 has been peeled off. The entire area surrounding the located pocket 23 is pressed against the frame upper surface area 31R by the rectangular frame-shaped pressing surface 41K. In these configurations, the entire periphery of the pocket 23 located at the component supply position 13K is pressed against the frame upper surface region 31R, so that the occurrence of pickup mistakes due to the fluttering of the carrier tape 20 can be further reduced. It will be possible.

As described above, the tape feeder 13 in the present embodiment covers the upper wall portion 32a of the cover member 32 provided by covering the frame upper surface region 31R, which is a region exposed on the upper surface of the frame 31 of the tape passage 31L, from above. Is provided with a tape holding portion 41. The tape holding portion 41 is located at the component supply position 13K of the base tape 21 from which the top tape 22 has been peeled at the peeling position 32H by the pressing surface 41K located below the lower surface 32K of the upper wall portion 32a of the cover member 32. The vicinity of the located pocket 23 is pressed from above. Therefore, even if the carrier tape 20 flutters, the pocket 23 which is in the upward open state due to the peeling of the top tape 22 does not move up and down, and the component BH in the pocket 23 is in a stable state and the component supply position. It is supplied to 13K, and the occurrence of pickup mistakes is suppressed.

Further, in the process of providing the tape holding portion 41 on the upper wall portion 32a of the cover member 32 in this way, the parallelism of the lower surface 32K of the upper wall portion 32a of the cover member 32 with respect to the frame upper surface region 31R at the time of manufacturing the cover member 32 is obtained. It can be done at a lower cost than performing advanced processing. Therefore, according to the tape feeder 13 in the present embodiment, it is possible to reduce the occurrence of pickup mistakes caused by the fluttering of the carrier tape while suppressing the cost.

Although the embodiments of the present invention have been described so far, the present invention is not limited to the above-mentioned ones, and various modifications and the like are possible. For example, in the above-described embodiment, the peeling position 32H is the trailing edge (edge on the worker OP side) of the part outlet 32G of the cover member 32, and the peeling position 32H is composed of a part of the component outlet 32G. However, the peeling position 32H does not necessarily have to consist of a part of the component outlet 32G. Therefore, an opening may be provided on the rear side (upstream side of the flow of the carrier tape 20) of the component outlet 32G, and the trailing edge of the opening may be the peeling position 32H.

Provided is a tape feeder capable of reducing the occurrence of pickup mistakes caused by the fluttering of a tape member while suppressing the cost.
