This tape tip processing jig includes: a cutting jig that cuts a carrier tape including a base tape having cavities arranged at a predetermined interval in the longitudinal direction and a cover tape covering the cavities; a clamping part that clamps a tip of a remaining part of the carrier tape cut by the cutting jig from above and below; and a push-up part that deforms the tip of the remaining part of the carrier tape clamped by the clamping part into a protruding shape.

Description

Tape tip processing jig

This specification relates to a tape tip processing jig.

Conventionally, there has been known a device that cuts the carrier tape and processes the tip of the carrier tape (see Patent Document 1, for example). A carrier tape is a tape in which a cover tape is attached to a base tape in which electronic components are housed in cavities arranged at predetermined intervals in the longitudinal direction. The carrier tape is loaded into the tape feeder while wound on a tape reel. In the auto loading feeder, when the tip of the carrier tape is inserted into the tape entrance, the carrier tape is guided and transported. When the cover tape is peeled off from the base tape by inserting a peeling blade between the base tape and the cover tape at the leading end of the carrier tape during such transportation, the electronic components in the cavity are exposed so as to be removable.

The apparatus described in Patent Document 1 above includes a cutting member that cuts the carrier tape and a pressing member that presses the upper surface of the carrier tape. After the carrier tape is cut by the cutting member, the pressing member obliquely presses the corners of the upper surface of the leading end of the carrier tape. When such pressing is completed and the pressing member is retracted, the cover tape returns to its original flat state while the base tape is maintained in an inclined state. Therefore, a gap recessed in the longitudinal direction of the tape can be formed between the base tape and the cover tape on the cut surface of the carrier tape. Therefore, it is possible to properly insert the peeling blade between the base tape and the cover tape.

Japanese Patent No. 5909690

However, if the cover tape is in a state where it easily bends in a convex downward shape, when the peeling blade is inserted between the base tape and the cover tape, the cover tape tends to escape into the above-mentioned gap, and the peeling blade does not move the base tape. and the cover tape, the cover tape may not be properly peeled off.

The present specification aims to provide a tape leading end processing jig capable of cutting the carrier tape and giving the cover tape a bending habit that makes it difficult for the cover tape to bend downward when normally peeling the cover tape from the base tape. aim.

This specification includes a cutting jig section for cutting a carrier tape having a base tape provided with cavities arranged at predetermined intervals in the longitudinal direction and a cover tape covering the cavities, and cutting by the cutting jig section. a tape front end processing jig comprising: a clamping portion that vertically clamps the front end portion of the uncut portion of the carrier tape that has been cut; Disclose.

According to the present disclosure, the carrier tape is cut by the cutting jig portion, and after the cutting, the carrier tape is pushed up by the push-up portion in a state in which the tip portion of the carrier tape on the side of the remaining cut portion of the carrier tape is sandwiched from above and below by the sandwiching portion. is deformed into a convex shape. For this reason, the cover tape at the leading end of the cut carrier tape has a shape with a convex bend. Therefore, it is possible to cut the carrier tape and give the cover tape a curl that makes it difficult for the cover tape to bend downward when the cover tape is normally peeled off from the base tape.

An embodiment of a tape leading edge processing jig according to the present disclosure will be described below.

1. Outline As shown in FIGS. 1 and 2, the tape leading end processing jig 1 is a jig for cutting the carrier tape 10 and processing the leading end of the carrier tape 10 (see FIGS. 3 and 4). The carrier tape 10 is a tape mainly loaded into an auto loading feeder 20 (see FIG. 5). When the carrier tape 10 is inserted into the tape entrance, the auto loading feeder 20 automatically conveys the carrier tape 10 while processing it to expose the electronic component 2 so that it can be taken out.

2. Configuration of Carrier Tape The carrier tape 10 is a tape that accommodates a plurality of electronic components 2 . The electronic component 2 is a component mounted on an electronic substrate, and includes, for example, a minute component such as 0201 size (0.2 mm×0.1 mm) to a large component. The carrier tape 10 has a base tape 11 and a cover tape 19, as shown in FIGS.

The base tape 11 has cavities 12 . The cavity 12 is an accommodation space that accommodates the electronic component 2 . The base tape 11 is made of a flexible material such as resin. The base tape 11 has a planar portion 13 formed in a planar shape and a projecting portion 14 projecting downward from the planar portion 13 . The cavity 12 is provided within the projecting portion 14 and is open on the plane portion 13 side. The projections 14 and the cavities 12 are arranged side by side at predetermined intervals in the longitudinal direction of the tape. The carrier tape 10 is an embossed tape having cavities 12 in protrusions 14 .

The base tape 11 is also provided with feed holes 15 penetrating therethrough. The feed hole 15 is a feed hole with which the engaging projection of the sprocket of the auto loading feeder 20 engages. The feed hole 15 is formed in a substantially circular or elliptical shape. The feed holes 15 are arranged side by side at predetermined intervals in the longitudinal direction of the tape. The cavities 12 are arranged in a row in the tape longitudinal direction on one side in the tape width direction (for example, the right side with respect to the tape conveying direction Y as shown in FIG. 5). Also, the feed holes 15 are arranged in a row in the tape longitudinal direction on the other side in the tape width direction (eg, the left side with respect to the tape transport direction Y).

The plane portion 13 has a first plane portion 13a, a second plane portion 13b, and a connecting portion 13c. The first flat portion 13a is a flange-like portion provided on the other side in the longitudinal direction of the tape, that is, on the side where the feed holes 15 are arranged. The second plane portion 13b is a flange-like portion provided on one side in the tape longitudinal direction. The first plane portion 13a and the second plane portion 13b each extend in the longitudinal direction of the tape. The connecting portion 13c is a portion provided between two projecting portions 14 adjacent in the longitudinal direction of the tape at a position sandwiched between the first flat portion 13a and the second flat portion 13b. The connecting portion 13c connects the upper portions of the two projecting portions 14 to each other. The connecting portion 13c is formed thinner than the projecting portion 14. As shown in FIG.

The connecting portion 13c is also formed thinner than the other flat portions 13, that is, the first flat portion 13a and the second flat portion 13b. In other words, the connecting portion 13 c may be provided with a recess 16 whose upper end position is lower than that of the other flat portion 13 .

A cover tape 19 is a tape that covers the cavity 12 . The cover tape 19 is made of plastic such as a transparent polymer film. The cover tape 19 is attached to the upper surface of the base tape 11 with an adhesive. The cover tape 19 is attached to both sides of the cavity 12 in the width direction while avoiding the cavity 12 . The cover tape 19 may be formed so as to exclude the portion where the feed holes 15 are provided. The cover tape 19 closes the upper portion of the cavity 12 of the base tape 11 to prevent the parts accommodated in the cavity 12 from jumping out.

3. Configuration of Auto-Loading Feeder The auto-loading feeder 20 is a device that feeds the electronic components 2 in the cavity 12 to the component pick-up position by conveying the carrier tape 10 inserted into the tape entrance. The auto loading feeder 20 is detachably attached to a slot of a component mounting machine provided on a board production line for producing boards. The electronic component 2 supplied from the auto loading feeder 20 to the component pick-up position is sucked and held by a suction nozzle or the like attached to the mounting head of the component mounting machine, and then mounted on the electronic board by releasing the suction.

The auto-loading feeder 20 conveys the carrier tape 10 by rotating the sprocket provided below the tape conveying path and engaging the engagement projections of the sprocket with the feed holes 15 of the carrier tape 10 . The auto loading feeder 20 has a tape guide 21 as shown in FIG.

The tape guide 21 is a guide member that holds and guides the carrier tape 10 that engages the engagement protrusions of the sprockets in the feed holes 15 . The tape guide 21 is formed to have a U-shaped cross section so as to abut on the upper surface and side surfaces of the carrier tape 10 . The upper surface of the tape guide 21 has an aperture 22 extending therethrough. The opening hole 22 is provided at a component extraction position where the electronic component 2 is extracted from the cavity 12 .

The tape guide 21 has a peeling blade 23. The peeling blade 23 is a blade portion for peeling the cover tape 19 from the base tape 11 to expose the electronic components in the cavity 12 . The peeling blade 23 is provided upstream in the tape transport direction Y from the opening 22 on the upper surface of the tape guide 21, and extends from the tape transport direction Y downstream side toward the tape transport direction Y upstream side. The peeling blade 23 is inserted between the base tape 11 and the cover tape 19 at the leading end of the carrier tape 10 while the carrier tape 10 is being transported.

When the carrier tape 10 is inserted into the tape entrance of the auto-loading feeder 20, the sprocket on the tape entrance side is fed in the tape transport direction Y by rotating the sprocket while the feed hole 15 is engaged with the sprocket. Further, the carrier tape 10 is then fed into the tape guide 21 and held thereon, and is further fed in the tape feeding direction Y by rotating the sprocket on the tape exit side with the feed hole 15 engaged with the sprocket.

During tape transport, the carrier tape 10 is separated from the base tape 11 and the cover tape 19 by inserting the peeling blade 23 of the tape guide 21 between the base tape 11 and the cover tape 19 at the leading end of the carrier tape 10 . becomes stripped. When the cover tape 19 is peeled off, the electronic component 2 in the cavity 12 of the base tape 11 is exposed so as to be removable. After that, when the electronic component 2 reaches the component extraction position of the opening hole 22, it is sucked and held by a suction nozzle or the like and transferred to the electronic substrate.

By the way, particularly in the carrier tape 10 in which the recesses 16 are provided in the connecting portions 13c as described above, the cover tape 19 tends to be bent in a convex downward shape until it comes into contact with the upper surface of the connecting portions 13c. However, if the cover tape 19 remains prone to bending downward, the cover tape 19 will be bent downward when the peeling blade 23 is inserted between the base tape 11 and the cover tape 19 as shown in FIG. It bends and becomes easy to escape to said recess 16. As shown in FIG. Therefore, the peeling blade 23 may not be properly inserted between the base tape 11 and the cover tape 19, and the cover tape 19 may not be properly peeled off.

4. Configuration of Tape Leading Edge Processing Jig The tape leading edge processing jig 1 cuts the carrier tape 10 to form a cut surface, and the cover tape 19 does not easily bend downward at the leading end of the cut carrier tape 10 on the side of the cut residue. Transform so that it becomes

The timing at which the tape leading edge processing jig 1 cuts the carrier tape 10 and deforms the leading edge is preferably immediately before the carrier tape 10 is inserted into the tape entrance of the auto loading feeder 20, for example. Moreover, the tape leading end processing jig 1 may be arranged near a workbench where an operator inserts the carrier tape 10 into the tape entrance of the auto loading feeder 20, or may be carried by the operator himself/herself. Alternatively, it may be installed in a device that processes the leading end of the carrier tape 10 .

The tape leading edge processing jig 1 includes a cutting jig portion 30 as shown in FIGS. The cutting jig section 30 is a jig for cutting the carrier tape 10 .

The heating portion 81 is embedded mainly in the vicinity of the upper surface of the push-up portion 80 that is in contact with the lower surface of the connecting portion 13c of the carrier tape 10 . The heating temperature of the heating part 81 makes it easy to deform the leading end of the carrier tape 10 (especially the connecting part 13c and the cover tape 19) and maintains the deformed state for a long time (for example, half a day to a day). The temperature is set at a temperature (for example, 60° C. to 80° C.).

The heating unit 81 is, for example, a heating wire. When the heating unit 81 is a heating wire, the heating unit 81 performs heating by power supply from the power supply 82 . The power supply 82 is a battery, a small battery, or the like that can be mounted in the tape leading edge processing jig 1 . When the operator turns on the switch 83, the heating unit 81 is supplied with power from the power source 82 and performs heating. The switch 83 may be operably attached to the surface of the tape leading end processing jig 1 .

The tape leading end processing jig 1 includes a feed hole jig portion 90 as shown in FIGS. The feed hole jig portion 90 is a jig for changing the size of the feed holes 15 of the carrier tape 10, and engages the engagement projection of the sprocket of the auto loading feeder 20 with the feed hole 15 at the head of the carrier tape 10. It is a jig to make it easier.

The feed hole jig section 90 has the above-described auxiliary pedestal section 45 as a pedestal section on which the carrier tape 10 is placed.

Specifically, first, the operator applies force to the first power point portion 33 of the cutting jig portion 30 to separate the upper cutting edge 31a from the lower cutting edge 32a and position it upward. Then, the operator locates the cut portion of the carrier tape 10, places the carrier tape 10 on the main body pedestal portion 41 in a state where the carrier tape 10 is passed between the upper blade edge 31a and the lower blade edge 32a, and then places the carrier tape 10 on the main body pedestal portion. The positioning portion 43 of 41 is inserted into the feed hole 15 of the carrier tape 10 . When two or more types of guide portions 42 are provided on the main body pedestal portion 41 in the tape leading end processing jig 1, the guide portion 42 corresponding to the size of the cavity 12 of the carrier tape 10 and eventually the electronic component 2 is selected. , the carrier tape 10 is placed along the selected guide portion 42 .

After that, the operator applies force to the first force point portion 33 to perform a cutting operation to bring the upper cutting edge 31a closer to the lower cutting edge 32a. When the carrier tape 10 is cut with respect to the cutting jig portion 30 in a state in which the positioning portion 43 is inserted into the feed hole 15 of the carrier tape 10, the upper cutting edge 31a and the lower cutting edge 32a are brought together to cut the carrier tape. 10 is cut near the center in the tape longitudinal direction of the connecting portion 13c between two protruding portions 14 adjacent in the tape longitudinal direction.

After the carrier tape 10 is cut as described above, the operator places the carrier tape 10 on the main body pedestal portion 41, and then applies force to the second force point portion 71 of the arm member 70, A sandwiching operation is performed so that the upper support portion 61 and the lower support portion 62 sandwich the leading end portion of the carrier tape 10 on the side of the remaining cut portion. When such a clamping operation is performed, as shown in FIG. 10, the upper support portion 61 and the lower support portion 62 sandwich the leading end portion of the carrier tape 10, and the push-up portion 80 presses the joint portion 13c of the leading end portion of the carrier tape 10. in contact with the lower surface of the carrier tape 10 and push up the connecting portion 13c of the carrier tape 10 and the cover tape 19 corresponding thereto.

When the clamping operation described above is performed and the cover tape 19 is pushed up by the push-up portion 80 , the joining portion 13 c of the carrier tape 10 and the cover tape 19 are heated by the heating portion 81 . Further, the holding operation described above is continuously performed for, for example, several seconds to ten-odd seconds.

Then, when the above clamping operation is completed, the operator releases the clamping operation and moves the upper support part 61 and the lower support part 62 away from each other. In this state, when the leading end of the carrier tape 10 is pulled out from the main body base portion 41, the carrier tape 10 is deformed so that the cover tape 19 and the connecting portion 13c are bent upwardly as shown in FIG. Become. Then, the operator inserts this carrier tape 10 into the tape entrance of the auto loading feeder 20 .

As described above, in the tape leading edge processing jig 1, when the carrier tape 10 is cut with respect to the first force point portion 33 of the cutting jig portion 30, the upper cutting edge 31a and the lower cutting edge 32a are brought together. , the carrier tape 10 is cut. Further, after the carrier tape 10 is cut, when the tip portion of the carrier tape 10 is pinched against the second force point portion 71 of the arm member 70, the first plane portion 13a and the second plane portion of the carrier tape 10 With the portion 13 b and the cover tape 19 sandwiched between the holding portions 60 , the connecting portion 13 c and the cover tape 19 of the carrier tape 10 are pushed up by the push-up portion 80 .

When the carrier tape 10 is pushed up by the push-up part 80, the leading end of the carrier tape 10 is curved and deformed so that the cover tape 19 at the leading end of the carrier tape 10 is bent upwardly. becomes a shape with Then, when the carrier tape 10 is inserted into the tape entrance of the auto loading feeder 20, the cover tape 19 is peeled off by the peeling blade 23 in a state where the cover tape 19 at the tip of the carrier tape 10 has the aforementioned curl. done.

In such a configuration, when the cover tape 19 is peeled off from the base tape 11 by the peeling blade 23, the cover tape 19 has a tendency to bend upward, causing the cover tape 19 to bend downward. It becomes difficult to bend convexly. Therefore, even when peeling is performed by the peeling blade 23, the cover tape 19 can be prevented from escaping into the recess 16 of the connecting portion 13c. Therefore, according to the tape leading end processing jig 1, the peeling blade 23 can be appropriately inserted between the base tape 11 and the cover tape 19 of the carrier tape 10, and the cover tape 19 can be easily peeled normally. be able to.

Further, according to the tape leading end processing jig 1, the operator performs a cutting operation for cutting the carrier tape 10 while the carrier tape 10 is placed on the main body pedestal portion 41, and the operator performs a cutting operation for cutting the carrier tape 10, and It is possible to realize both of a clamping operation for imparting a tendency to bending. Therefore, it is not necessary to prepare separate jigs for performing the cutting operation and the clamping operation of the carrier tape 10, and the jigs can be shared.

Therefore, the work from the cutting operation to the clamping operation of the carrier tape 10 can be realized without moving or transferring the carrier tape 10, so that the total working time and labor of the operator can be reduced. can be done.

In the tape leading end processing jig 1, the main body pedestal portion 41 is a positioning portion that positions the carrier tape 10 cut by the cutting jig portion 30 and the leading end portion of the carrier tape 10 that is deformed by the push-up portion 80. 43. Therefore, the carrier tape 10 can be accurately positioned when the cutting jig 30 cuts the carrier tape 10 and when the push-up unit 80 pushes up the leading end of the carrier tape 10 to deform it. Therefore, the cutting of the carrier tape 10 by the cutting jig portion 30 and the pushing-up deformation of the leading end portion of the carrier tape 10 by the pushing-up portion 80 can be appropriately performed at desired portions of the carrier tape 10 .

Further, as described above, the main body pedestal portion 41 can be moved and fixed to an arbitrary position in the extending direction of the lower cutting edge 32a of the lower cutting portion 32 with respect to the base member 50. With such a configuration, when the carrier tape 10 is repeatedly cut at the same position of the lower cutting edge 32a and the upper cutting edge 31a, or when the lower cutting edge 32a and the upper cutting edge 31a are broken, the main body pedestal portion 41 is cut. The position of the guide portion 42 can be moved to an arbitrary extending direction position with respect to the lower cutting edge 32a, and the use of the tape leading end processing jig 1 can be continued. Therefore, the life of the tape leading end processing jig 1 can be extended.

In addition, in the tape leading edge processing jig 1 , the push-up section 80 has a heating section 81 that heats the leading edge of the carrier tape 10 . Therefore, the leading end of the carrier tape 10 can be easily deformed by heating, and the bending tendency of the cover tape 19 can be maintained for a long period of time.

Furthermore, when changing the size of the feed holes 15 of the carrier tape 10 , the operator places the carrier tape 10 on the auxiliary pedestal portion 45 and adjusts the positioning portion 47 of the auxiliary pedestal portion 45 to the feed holes 15 of the carrier tape 10 . insert into After that, the operator applies force to the second force point portion 71 of the arm member 70 , and the hole deformation portion 91 approaches the auxiliary base portion 45 to deform the feed hole 15 at the leading end of the carrier tape 10 . perform an operation. When such a hole deformation operation is performed, the hole deformation portion 91 is fitted into the feed hole 15 at the leading end of the carrier tape 10, and the feed hole 15 is expanded in diameter and deformed.

After deforming the feed hole 15 of the carrier tape 10, the operator cancels the above hole deformation operation and moves the hole deformation portion 91 away from the auxiliary base portion 45 to assist the leading end portion of the carrier tape 10. It is pulled out from the pedestal portion 45 . Then, the operator inserts this carrier tape 10 into the tape entrance of the auto loading feeder 20 .

As described above, in the tape leading end processing jig 1 , when the hole deformation operation of the carrier tape 10 is performed with respect to the second force point portion 71 , the leading end of the carrier tape 10 is deformed by the hole deformation portion 91 of the feed hole jig portion 90 . , the feed hole 15 is deformed to have an expanded diameter. Then, when the carrier tape 10 is inserted into the tape entrance of the auto loading feeder 20, the feeding hole 15 at the leading end of the carrier tape 10 is expanded and deformed, and the engaging protrusion of the sprocket is engaged with the feeding hole 15. Then, the carrier tape 10 is transported and the cover tape 19 is peeled off by the peeling blade 23 .

With this configuration, when inserting the carrier tape 10 into the auto-loading feeder 20, it is possible to easily engage the engagement projections of the sprocket with the feeding holes 15 of the carrier tape 10. Therefore, according to the tape leading end processing jig 1, the carrier tape 10 can be conveyed in the auto loading feeder 20 and the cover tape 19 can be peeled off by the peeling blade 23 appropriately.

Further, according to the tape leading end processing jig 1, apart from the above-described cutting operation and clamping operation, while the carrier tape 10 is placed on the auxiliary pedestal portion 45, the feed hole of the carrier tape 10 is deformed by the operator. It is possible to perform a hole deformation operation that causes Therefore, it is not necessary to prepare separate jigs for performing the cutting operation, the clamping operation, and the hole deformation operation of the carrier tape 10, and the jigs can be shared.

In addition, the second force point portion 71 is common to the force point portion to which the worker applies force when performing the hole deformation operation and the force point portion to which the worker applies force when the worker performs the pinching operation. That is, when a force is applied to the second force point portion 71 while the carrier tape 10 is placed on the main body pedestal portion 41, the leading end portion of the carrier tape 10 is held by the holding portion 60 and pushed up by the push-up portion 80.
