Abstract

Provided is a tape tip processing jig that processes a tip of a carrier tape, which includes a base tape having cavities arranged at a predetermined interval in the longitudinal direction and a cover tape covering the cavities, so that the cover tape is unlikely to warp downward and can be normally removed from the base tape. This tape tip processing jig includes a clamping part that clamps the tip of the carrier tape from above and below and a push-up part that deforms the tip of the carrier tape clamped by the clamping part into a protruding shape.

Description

[Technical Field]

[0001] The present specification relates to a tape tip processing jig. [Background technology]

[0002] Conventionally, there has been known an apparatus for processing the leading end of a carrier tape (see, for example, Patent Document 1). The carrier tape is a tape in which a cover tape is affixed to a base tape that houses electronic components in cavities arranged at predetermined intervals in the longitudinal direction. The apparatus described in Patent Document 1 performs a process of bending the leading end of the carrier tape so as to form an inclined portion that slopes upward toward the leading end. The carrier tape is then loaded into a tape feeder while being wound around a tape reel. In an autoloading feeder, when the leading end of the carrier tape is inserted into a tape inlet, the carrier tape is guided and transported. During this transport, a peeling blade is inserted between the base tape and cover tape at the leading end of the carrier tape, and the cover tape is peeled off from the base tape, exposing the electronic components in the cavities so that they can be removed.

[0003] [Patent Document 1] Patent No. 5913047 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, there is an embossed carrier tape in which cavities are provided within protruding portions that protrude downward from the flat portion of the base tape. In the embossed tape, the protruding portions of the base tape are arranged at predetermined intervals in the longitudinal direction of the carrier tape, and a connecting portion is provided between the protruding portions as part of the flat portion, connecting the tops of both protruding portions. The connecting portion is formed to be thinner than the protruding portions. The carrier tape is cut so that the connecting portion becomes the tip, and a peeling blade is inserted into the connecting portion to peel the base tape from the cover tape.

[0005] On the other hand, the above-mentioned joint portion may have a recess whose upper end is lower than other flat portions of the base tape (for example, portions where feed holes are provided). When such a recess is provided in the joint portion, the cover tape tends to bend downward in a convex shape until it contacts the upper surface of the joint portion. If the cover tape continues to bend downward in a convex shape in this manner, the cover tape tends to escape into the recess when the peeling blade is inserted between the base tape and the cover tape, which may prevent the peeling blade from being properly inserted between the base tape and the cover tape, resulting in an improper peeling of the cover tape.

[0006] An object of the present specification is to provide a tape tip processing jig that can make it difficult for the cover tape to bend downward when peeling it off normally from the base tape. [Means for solving the problem]

[0007] This specification discloses a tape tip processing jig for processing the tip of a carrier tape having a base tape with cavities arranged at predetermined intervals in the longitudinal direction and a cover tape that covers the cavities, the tape tip processing jig comprising a clamping portion that clamps the tip from above and below, and a pushing-up portion that deforms the tip clamped by the clamping portion into a convex shape.

[0008] According to the present disclosure, the tip of the carrier tape is deformed into an upward convex shape by the push-up portion, so that the tip of the carrier tape has an upward convex bent shape, which makes it difficult for the cover tape to bend downward when peeling it off normally from the base tape.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, an embodiment of a tape tip processing jig according to the present disclosure will be described.

[0011] 1. Overview As shown in Fig. 1, the tape leading end processing jig 1 is a jig that processes the leading end of a carrier tape 10. The carrier tape 10 is a tape that is mainly loaded into an autoloading feeder 20 (see Fig. 4). When the carrier tape 10 is inserted into a tape inlet, the autoloading feeder 20 automatically processes and transports the carrier tape 10, exposing the electronic components 2 so that they can be removed.

[0012] 2. Carrier tape configuration The carrier tape 10 is a tape that accommodates multiple electronic components 2. The electronic components 2 are components that are mounted on an electronic substrate, and range from very small components such as 0201 size (0.2 mm x 0.1 mm) to large components. As shown in Figures 2 and 3, the carrier tape 10 has a base tape 11 and a cover tape 19.

[0013] The base tape 11 has cavities 12. The cavities 12 are storage spaces that store the electronic components 2. The base tape 11 is made of a flexible material such as resin. The base tape 11 has a flat portion 13 formed in a planar shape and protruding portions 14 that protrude downward from the flat portion 13. The cavities 12 are provided within the protruding portions 14 and are open on the side of the flat portion 13. The protruding portions 14, and therefore 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 in which the cavities 12 are provided within the protruding portions 14.

[0014] The base tape 11 is also provided with perforations 15. The perforations 15 are perforations that engage with engaging protrusions on a sprocket of the autoloading feeder 20. The perforations 15 are formed in a substantially circular or elliptical shape. The perforations 15 are arranged in a line at predetermined intervals in the tape longitudinal direction. The cavities 12 are arranged in a line in the tape longitudinal direction on one side in the tape width direction (for example, the right side in the tape transport direction Y). The perforations 15 are also arranged in a line in the tape longitudinal direction on the other side in the tape width direction (for example, the left side in the tape transport direction Y).

[0015] The flat portion 13 has a first flat portion 13a, a second flat portion 13b, and a connecting portion 13c. The first flat portion 13a is a flange-shaped portion provided on the other side in the tape longitudinal direction, i.e., the side where the sprocket holes 15 are located. The second flat portion 13b is a flange-shaped portion provided on one side in the tape longitudinal direction. The first flat portion 13a and the second flat portion 13b each extend in the tape longitudinal direction. The connecting portion 13c is a portion provided between two protruding portions 14 adjacent in the tape longitudinal direction, 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 protruding portions 14. The connecting portion 13c is formed to be thinner than the protruding portions 14.

[0016] The connecting portion 13c is also formed to be thinner than the other flat portions 13, i.e., the first flat portion 13a and the second flat portion 13b. That is, the connecting portion 13c may be provided with a recess 16 whose upper end is lower than the other flat portions 13.

[0017] The 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, 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 in the base tape 11, preventing the component housed in the cavity 12 from jumping out.

[0018] 3.Auto-loading feeder configuration The autoloading feeder 20 is a device that feeds electronic components 2 in the cavities 12 to a component removal position by transporting the carrier tape 10 inserted into the tape inlet. The autoloading feeder 20 is detachably mounted in a slot of a component mounting machine installed on a board production line that produces boards. The electronic components 2 supplied from the autoloading feeder 20 to the component removal position are sucked and held by a suction nozzle attached to the mounting head of the component mounting machine, and then the suction is released to mount the electronic components on the electronic board.

[0019] The autoloading feeder 20 conveys the carrier tape 10 by rotating a sprocket provided below the tape conveying path and engaging the engaging protrusions of the sprocket with the feed holes 15 of the carrier tape 10. The autoloading feeder 20 has a tape guide 21 as shown in FIG.

[0020] The tape guide 21 is a guide member that holds and guides the carrier tape 10, the engagement protrusions of the sprocket engaging with the feed holes 15. The tape guide 21 is formed with a U-shaped cross section so as to abut against the top and side surfaces of the carrier tape 10. The top surface of the tape guide 21 has an opening hole 22 that passes through it. The opening hole 22 is provided at a component removal position where the electronic component 2 is removed from the cavity 12.

[0021] The tape guide 21 has a peeling blade 23. The peeling blade 23 is a blade portion that peels 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 feeding direction Y of the opening hole 22 on the top surface of the tape guide 21, and extends from the downstream side to the upstream side in the tape feeding direction Y. The peeling blade 23 is inserted between the base tape 11 and the cover tape 19 at the tip of the carrier tape 10 while the carrier tape 10 is being fed.

[0022] When the carrier tape 10 is inserted into the tape inlet of the autoloading feeder 20, the sprocket on the tape inlet side rotates with the feed holes 15 engaged with the sprocket, thereby feeding the carrier tape 10 in the tape feed direction Y. The carrier tape 10 then enters and is held by the tape guide 21, while the sprocket on the tape outlet side rotates with the feed holes 15 engaged with the sprocket, thereby further feeding the carrier tape 10 in the tape feed direction Y.

[0023] Then, during tape transport, the peeling blade 23 of the tape guide 21 is inserted between the base tape 11 and the cover tape 19 at the tip of the carrier tape 10, so that the cover tape 19 is peeled off from the base tape 11. When the cover tape 19 is peeled off, the electronic components 2 in the cavities 12 of the base tape 11 are exposed and can be removed. When the electronic components 2 subsequently reach the component removal position of the openings 22, they are sucked and held by a suction nozzle or the like and transferred to an electronic board.

[0024] In the carrier tape 10 having the recess 16 formed in the connecting portion 13c as described above, the cover tape 19 tends to bend downward in a convex shape until it contacts the upper surface of the connecting portion 13c. However, if the cover tape 19 continues to bend downward in a convex shape, as shown in Figure 5, when the peeling blade 23 is inserted between the base tape 11 and the cover tape 19, the cover tape 19 tends to bend downward and escape into the recess 16. This can cause the peeling blade 23 to be improperly inserted between the base tape 11 and the cover tape 19, resulting in an improper peeling of the cover tape 19.

[0025] 4. Configuration of tape end processing jig The tape tip processing jig 1 processes the tip of the carrier tape 10 so that the cover tape 19 is less likely to bend downward. The carrier tape 10 is in a state in which it has been cut in advance near the center of the tape longitudinal direction at the joint 13c between two protrusions 14 adjacent in the tape longitudinal direction. The tip of the carrier tape 10 to be processed by the tape tip processing jig 1 is the flat portion 13 including the joint 13c of the base tape 11 and the portion of the cover tape 19 corresponding to the flat portion 13.

[0026] It is preferable that the timing for the tape leading edge processing jig 1 to process the leading edge of the carrier tape 10 is, for example, immediately before the carrier tape 10 is inserted into the tape inlet of the autoloading feeder 20. The tape leading edge processing jig 1 may be placed near a workbench where an operator inserts the carrier tape 10 into the tape inlet of the autoloading feeder 20, or may be carried by the operator himself, or may be mounted on a device that processes the leading edge of the carrier tape 10.

[0027] As shown in Figures 6, 7, 8, and 9, the tape end processing jig 1 is equipped with clamping sections 30. The tape end processing jig 1 may be a jig integrated with two or more types of clamping sections 30 provided to match the size of the cavity 12 and therefore the electronic component 2. For example, when two types of clamping sections 30 are provided as shown in Figure 6, one clamping section 30A corresponds to a size of less than 2 mm, and the other clamping section 30B corresponds to a size of 2 mm or more.

[0028] The clamping portion 30 is a portion that clamps the leading end portion of the carrier tape 10 (particularly, the first and second planar portions 13a and 13b of the planar portion 13 and the cover tape 19 corresponding to these planar portions 13a and 13b) from above and below. The clamping portion 30 has an upper support portion 31, a lower support portion 32, a support pin 33, an insertion opening 34, and a biasing portion 35.

[0029] The upper support portion 31 is a portion that abuts against the upper surface of the leading end of the carrier tape 10 to support the carrier tape 10 when the carrier tape 10 is sandwiched. The lower support portion 32 is a portion that abuts against the lower surface of the leading end of the carrier tape 10 to support the carrier tape 10 when the carrier tape 10 is sandwiched. The upper support portion 31 and the lower support portion 32 are each formed in a plate shape with a U-shaped cross section. Specifically, the upper support portion 31 is formed in a gutter shape that is convex upward and has an opening facing downward. The lower support portion 32 is formed in a gutter shape that is convex downward and has an opening facing upward. The opening width of the lower support portion 32 is set to be equal to or greater than the width of the upper support portion 31 so that the upper support portion 31 can fit into it.

[0030] The upper support portion 31 and the lower support portion 32 are supported at one longitudinal end portion so that they can swing relative to each other. The upper support portion 31 and the lower support portion 32 are connected to each other at one longitudinal end portion via a support pin 33. That is, the support pin 33 supports the upper support portion 31 and the lower support portion 32 so that they can swing. The upper support portion 31 and the lower support portion 32 are configured so that their other longitudinal ends can move toward and away from each other by swinging. An insertion opening 34 is provided at the other longitudinal end portion of the upper support portion 31 and the lower support portion 32, through which the leading end of the carrier tape 10 is inserted. The insertion opening 34 is provided between the other longitudinal end portion of the upper support portion 31 and the other longitudinal end portion of the lower support portion 32.

[0031] The biasing portion 35 is a member that generates a biasing force that biases the upper support portion 31 and the lower support portion 32 in directions that move them away from each other (i.e., in the up-down direction). The biasing portion 35 is, for example, a torsion coil spring or a torsion bar. The upper support portion 31 and the lower support portion 32 are biased by the biasing portion 35 in a direction that widens the insertion opening 34, and their movement is restricted by a stopper 50 when the insertion opening 34 is fully open. The upper support portion 31 and the lower support portion 32 are normally in a state in which the insertion opening 34 is fully open, and when the upper support portion 31 and the lower support portion 32 are pressed toward each other at the other longitudinal ends against the biasing force of the biasing portion 35, the insertion opening 34 is closed in a direction that narrows the insertion opening 34.

[0032] The upper support part 31 has a guide part 36. The guide part 36 is a part that guides the carrier tape 10 when the leading end of the carrier tape 10 is inserted into the insertion opening 34. The guide part 36 is formed in a gutter shape that convex downward and has an opening facing upward. The guide part 36 has an opening width that is larger than the expected width of the protruding part 14 of the carrier tape 10 and smaller than the overall tape width of the carrier tape 10. The guide part 36 is arranged in the insertion opening 34. The guide part 36 is attached and fixed to the back side of the upper wall of the main body of the upper support part 31. The guide part 36 is arranged within the insertion opening 34 and is formed to protrude from the main body of the upper support part 31 to the outside of the insertion opening 34, that is, the front side.

[0033] The guide portion 36 has a tape support portion 37. The tape support portion 37 is a portion that contacts and supports the underside of the first flat portion 13a and the second flat portion 13b of the carrier tape 10 from the attachment point of the guide portion 36 to the upper wall of the main body of the upper support portion 31 to the protruding tip. The tape support portion 37 is the upper end surface of both side walls of the guide portion 36 and extends from the protruding tip to a position deeper than the tip of the upper wall of the main body of the upper support portion 31. The guide portion 36 accommodates the protruding portion 14 of the carrier tape 10 inside the opening, and supports the first flat portion 13a and the second flat portion 13b of the carrier tape 10 at the tape support portion 37 from the protruding tip to a position deeper than the tip of the upper wall of the main body of the upper support portion 31.

[0034] The guide portion 36 has a stopper portion 39. The stopper portion 39 is a portion that positions the leading end of the carrier tape 10 when the carrier tape 10 is deformed by the push-up portion 40. The stopper portion 39 is an end surface facing the protruding leading end, which is formed between the attachment point of the guide portion 36 to the upper wall of the main body and the tape support portion 37. The leading end surface of the carrier tape 10 inserted into the insertion opening 34 abuts against the stopper portion 39, thereby positioning the leading end of the carrier tape 10.

[0035] When the carrier tape 10 is inserted into the insertion opening 34, the protruding portion 14 of the carrier tape 10 is accommodated inside the opening of the guide portion 36, and the first flat portion 13a and the second flat portion 13b are supported by the tape support portion 37, and eventually the leading end surface of the carrier tape 10 comes into contact with the stopper portion 39 and is positioned. Note that when the leading end surface of the carrier tape 10 comes into contact with the stopper portion 39 and is positioned, the end face of the leading protruding portion 14 of the carrier tape 10 may come into contact with or adjacent to the front end surface 40b of the push-up portion 40 described below.

[0036] The tape leading end processing jig 1 is equipped with a push-up portion 40. The push-up portion 40 is a portion that deforms the leading end of the carrier tape 10 held by the clamping portion 30 (particularly the connecting portion 13c and the cover tape 19 corresponding to the connecting portion 13c) into an upwardly convex shape. The push-up portion 40 is provided on the lower support portion 32. That is, the lower support portion 32 has the push-up portion 40. The push-up portion 40 is attached and fixed to the upper wall of the main body of the lower support portion 32. The push-up portion 40 extends upward in a block shape from the upper wall of the main body of the lower support portion 32.

[0037] When the leading end of the carrier tape 10 is clamped between the upper support portion 31 and the lower support portion 32, the upper surface of the tape support portion 37 of the guide portion 36 is positioned below the upper end surface 40a of the push-up portion 40. This is because the lower surface of the connecting portion 13c at the leading end of the carrier tape 10 comes into contact with the upper end surface 40a of the push-up portion 40, so that the leading end is pushed upward by the push-up portion 40.

[0038] When the tip end of the carrier tape 10 is positioned by the tip end surface of the carrier tape 10 abutting against the stopper portion 39, and the first flat portion 13a and second flat portion 13b of the tip end of the carrier tape 10 and the cover tape 19 corresponding to the connecting portion 13c are clamped by the clamping portion 30, the upper end surface 40a of the pushing-up portion 40 pushes upward the connecting portion 13c of the tip end of the carrier tape 10 and the cover tape 19 corresponding to the connecting portion 13c.

[0039] The upper support part 31 has a window part 31a. The window part 31a is a through-hole that penetrates the upper wall of the main body of the upper support part 31 in the vertical direction. The window part 31a is a part that allows an operator to visually check the positional relationship between the stopper part 39 and the leading end of the carrier tape 10 inserted into the insertion opening 34. Through the window part 31a, the operator can visually check whether the leading end surface of the carrier tape 10 inserted into the insertion opening 34 is abutting against the stopper part 39. The window part 31a is formed in, for example, a rectangular or elliptical shape. Furthermore, the window part 31a can serve as a space that allows the leading end of the carrier tape 10 that is pushed up by the push-up part 40 when the leading end of the carrier tape 10 is clamped by the clamping part 30 to escape.

[0040] The upper support part 31 also has a marker line 31b. The marker line 31b is a line segment provided on the upper surface of the upper wall of the main body of the upper support part 31. The marker line 31b is an auxiliary line formed so as to form a straight line with the line segment formed by the leading end surface of the carrier tape 10 when the operator visually views the carrier tape 10 through the window part 31a with the leading end surface of the carrier tape 10 abutting against the stopper part 39. The marker line 31b is an auxiliary line that serves as a guide when the operator inserts the carrier tape 10 into the insertion opening 34 while visually checking the positional relationship between the stopper part 39 and the leading end of the carrier tape 10 through the window part 31a. The marker lines 31b are preferably provided on both sides of the window part 31a on the upper surface of the upper wall of the main body of the upper support part 31.

[0041] As shown in Fig. 10, the push-up section 40 has a heating section 41. The heating section 41 is a section that heats the leading end of the carrier tape 10. The heating section 41 is embedded in the push-up section 40 mainly in the vicinity of the upper end surface 40a that contacts the underside of the joint 13c of the carrier tape 10. The heating temperature of the heating section 41 is set to a temperature (e.g., 60°C to 80°C) that makes it easy to deform the leading end of the carrier tape 10 (particularly the joint 13c and the cover tape 19) and can maintain the deformed state for a long period of time (e.g., half a day to a day).

[0042] The heating unit 41 is, for example, an electric heating wire. When the heating unit 41 is an electric heating wire, the heating unit 41 performs heating by receiving power from a power source 42. The power source 42 is a battery or a small battery that can be mounted inside the tape tip processing jig 1. When an operator turns on a switch 43, the heating unit 41 receives power from the power source 42 and performs heating. The switch 43 may be attached to the surface of the tape tip processing jig 1 so that it can be operated.

[0043] 5. Operation of the tape end processing jig Before inserting the carrier tape 10 into the tape inlet of the autoloading feeder 20, the worker causes the tape tip processing jig 1 to process the leading end of the carrier tape 10. Before the worker presses the upper support portion 31 and the lower support portion 32 of the clamping portion 30 in a direction in which they approach each other against the biasing force of the biasing portion 35, the upper support portion 31 and the lower support portion 32 are in a state in which the insertion opening 34 is fully opened. In this state, the worker first inserts the leading end of the carrier tape 10 into the insertion opening 34 of the tape tip processing jig 1.

[0044] If the tape leading edge processing jig 1 has two or more types of clamping parts 30, a clamping part 30 corresponding to the size of the cavity 12 of the carrier tape 10 and therefore the electronic component 2 is selected, and the leading edge of the carrier tape 10 is inserted into the insertion opening 34 of the selected clamping part 30. The insertion of the carrier tape 10 into this insertion opening 34 is carried out while the carrier tape 10 is guided by the guide part 36 of the upper support part 31 until the leading edge surface of the carrier tape 10 abuts against the stopper part 39.

[0045] The operator performs the above insertion operation while visually checking the positional relationship between the stopper portion 39 and the leading end of the carrier tape 10 inserted into the insertion opening 34 through the window portion 31a opened in the top surface of the upper support portion 31. Then, when the above insertion operation is completed, the leading end of the carrier tape 10 is supported by the tape support portion 37 of the guide portion 36, as shown in Fig. 11. In this state, the carrier tape 10 is not in contact with the upper end surface 40a of the push-up portion 40 and is not pushed upward by the push-up portion 40, so the cover tape 19 remains in a state where it is likely to bend downward in a convex shape.

[0046] Next, the operator presses the other longitudinal end of the upper support portion 31 and the other longitudinal end of the lower support portion 32 of the clamping unit 30 toward each other against the biasing force of the biasing portion 35. This pressing operation is continued until the first flat portion 13a and the second flat portion 13b of the carrier tape 10 and the corresponding cover tape 19 are clamped between the upper support portion 31 (specifically, the guide portion 36) and the lower support portion 32 (specifically, the push-up portion 40). When this pressing operation is performed, as shown in FIG. 12 , the joint portion 13c of the carrier tape 10 and the cover tape 19 corresponding to the joint portion 13c are pushed upward by the push-up portion 40. During this pushing-up, the joint portion 13c of the carrier tape 10 and the cover tape 19 are heated by the heating portion 41. The pressing operation is continued for, for example, several seconds to several tens of seconds.

[0047] When the pressing operation is completed, the other longitudinal ends of the upper support portion 31 and the lower support portion 32 of the clamping portion 30 are urged away from each other by the urging force of the urging portion 35, thereby widening the insertion opening 34. When the leading end of the carrier tape 10 is pulled out of the insertion opening 34 in this state, the cover tape 19 and the connecting portion 13c of the carrier tape 10 are deformed and curved upward, as shown in Figure 13. The carrier tape 10 is then inserted into the tape inlet of the autoloading feeder 20.

[0048] In this way, in the tape tip processing jig 1, with the tip of the carrier tape 10 being clamped by the clamping unit 30, the joint 13c and cover tape 19 at the tip of the carrier tape 10 clamped by the clamping unit 30 are pushed upward by the push-up unit 40. When this processing is performed, the tip of the carrier tape 10 is curved and deformed in an upward convex shape, so that the cover tape 19 and joint 13c at the tip of the carrier tape 10 have an upward convex bent shape. Then, when the carrier tape 10 is inserted into the tape inlet of the autoloading feeder 20, the cover tape 19 is peeled off by the peeling blade 23 with the tip of the carrier tape 10 having the above-mentioned bent shape.

[0049] In this configuration, when the cover tape 19 is peeled off from the carrier tape 10 by the peeling blade 23, the cover tape 19 has a tendency to bend upward in a convex shape, making it difficult for the cover tape 19 to bend downward in a convex shape. This prevents the cover tape 19 from escaping into the recess 16 of the connecting portion 13c when peeling is performed by the peeling blade 23. Therefore, the tape tip processing jig 1 can properly insert the peeling blade 23 between the base tape 11 and the cover tape 19 of the carrier tape 10, making it easier to peel off the cover tape 19 normally.

[0050] In addition, in the normal state of the tape tip processing jig 1, the insertion opening 34 is in a maximum open state due to the biasing force of the biasing portion 35, but the upper support portion 31 and the lower support portion 32 of the clamping portion 30 are pressed toward each other against the biasing force to clamp the tip of the carrier tape 10 and use the push-up portion 40 to give the tip the above-mentioned bend.

[0051] In this configuration, when inserting the leading end of the carrier tape 10 into the insertion opening 34 of the tape leading end processing jig 1, the insertion opening 34 can be opened widely, facilitating the insertion of the leading end of the carrier tape 10 into the insertion opening 34. Then, by performing a pressing operation to shrink the insertion opening 34 after the insertion, the leading end of the carrier tape 10 can be deformed by being curved in an upward convex shape, facilitating the operation of imparting a bend to the leading end of the carrier tape 10.

[0052] Furthermore, in the tape leading end processing jig 1, the clamping unit 30 has a stopper unit 39 that positions the leading end of the carrier tape 10 to be deformed by the push-up unit 40. This allows the leading end to be positioned with high precision when the push-up unit 40 pushes up and deforms the leading end of the carrier tape 10. Therefore, the push-up unit 40 can reliably push up and deform the leading end of the carrier tape 10 at a desired location on the carrier tape 10.

[0053] Furthermore, in the tape leading end processing jig 1, the upper support portion 31 has a window portion 31a that allows the worker to visually check the positional relationship between the stopper portion 39 and the leading end of the carrier tape 10. This allows the worker to perform the positioning work of the leading end of the carrier tape 10 while visually checking through the window portion 31a whether the leading end surface of the carrier tape 10 is abutting against the stopper portion 39. This allows the leading end of the carrier tape 10 to be positioned with high precision, and the above-mentioned push-up deformation can be performed appropriately at the desired location of the carrier tape 10.

[0054] Additionally, the upper support portion 31 has a marking line 31b that the operator uses as a guide when inserting the carrier tape 10 into the insertion opening 34 while visually checking through the window portion 31a. This allows the operator to visually check the above positional relationship through the window portion 31a, thereby preventing the operator from making an error in positioning the leading end of the carrier tape 10. This improves the positioning accuracy of the leading end of the carrier tape 10, while allowing the carrier tape 10 to more appropriately perform the above-mentioned push-up deformation at the desired location.

[0055] Furthermore, in the tape tip processing jig 1, the push-up section 40 has a heating section 41 that heats the tip of the carrier tape 10. This makes it easier to deform the tip of the carrier tape 10 by heating, and the bent tip of the carrier tape 10 can be maintained for a longer period of time.

[0056] In the above embodiment, the carrier tape 10 is an embossed tape in which the cavities 12 are provided in the protruding portions 14 that protrude downward from the flat portion 13. However, the present disclosure is not limited to this, and the carrier tape 10 may be a paper tape in which the cavities 12 are provided in a recessed shape in the flat portion of the base tape 11.

[0057] The present disclosure is not limited to the above-described embodiments and modifications, and various modifications can be made without departing from the spirit of the present disclosure. [Explanation of symbols]
