FIG. 1 is a cross-sectional view of an upper mold and a lower mold of a carrier tape manufacturing apparatus according to Embodiment 1 of the present invention when viewed from the side. The carrier tape manufacturing apparatus 1 shown in FIG. 1 includes an upper mold (first mold) 2 and a lower mold (second mold) 4 that is fitted to the upper mold 2 and compresses and molds the base material 3. The upper die 2 has punches 21 that form a plurality of recesses 31 for housing electronic components on the surface (one surface) of the belt-like base material 3, punch holders 22 that hold the punches 21, and springs 23. And a stripper plate 24 connected to the punch holder 22. The belt-like base material 3 is conveyed at a predetermined pitch in a direction perpendicular to the paper surface of FIG. 1, and the concave portion 31 is formed by compression molding the base material 3 on which the punch 21 is conveyed. The stripper plate 24 is a member that holds the base material 3 so as not to move when the punch 21 is pulled out from the base material 3 after the base material 3 is compressed by the punch 21. The upper die 2 is provided with a stroke end block 25 that stabilizes the bottom dead center of the upper die 2 when fitted to the lower die 4 and determines the amount of penetration of the punch 21 into the base material 3. . The stroke end block 25 is not limited to being provided on the upper die 2 and may be provided on the lower die 4.

  The lower mold 4 has a die plate 41 on which the substrate 3 is placed. The die plate 41 has a groove 42 on the surface on which the substrate 3 is placed. The material of the punch 21 and the die plate 41 is, for example, a cemented carbide.

  FIG. 2 is a front view of the punch 21 used in the carrier tape manufacturing apparatus 1 according to Embodiment 1 of the present invention. The punch 21 shown in FIG. 2 has a comb shape in which five comb blades 26 are connected at a base 27. The punch 21 has a comb blade (comb blade) 26 and a base 27 formed integrally. The punch 21 can be attached to the upper mold 2 by holding the base 27 with the punch holder 22. The upper mold 2 may have a configuration in which a plurality of punches 21 each having a plurality of comb blades 26 arranged in a line are held by a punch holder 22. The comb blade 26e located at the end of the direction of arrow A (the direction in which the punch 21 moves relative to the conveyance direction of the substrate 3) compresses the substrate 3 from the other comb blades 26 (26a to 26d). The area of the surface is reduced. In particular, the comb blade 26e is smaller in width α (<width β) in the direction of arrow A on the surface on which the base material 3 is compressed than the other comb blades 26.

  FIG. 3 is a schematic diagram for explaining how the concave portion 31 once formed on the surface of the base material 3 is compressed again using the punch 21 of the carrier tape manufacturing apparatus 1 according to Embodiment 1 of the present invention. . As shown in FIG. 3, the recess 31 a once formed by the comb blade 26 positioned at the head in the direction of the arrow A (the direction in which the punch 21 moves relative to the conveyance direction of the base material 3) is formed in the direction of the arrow A. When recompressing (double punching) with the comb blade 26e located at the tail, the comb blade 26e located at the tail has a smaller area for compressing the substrate 3 than the other comb blades 26. The comb blade 26e located at the end does not cut a part of the recess 31a, and there is little possibility of breaking the shape of the recess 31a. In particular, since the comb blade 26e has a smaller width α (<width β) in the direction of the arrow A of the surface on which the substrate 3 is compressed than the other comb blades 26, the comb blade 26a located at the head temporarily When the formed recess 31a is compressed again by the comb blade 26e positioned at the tail, the comb blade 26e positioned at the tail does not cut a part of the recess 31a in the direction of arrow A, and There is little risk of breaking the shape. Here, when the base material 3 is compressed again with the comb blade 26, the case where the comb blade 26 is fitted into the recessed portion 31 once formed is included.

  Further, the distance γ between the comb blade 26e located at the tail end in the direction of the arrow A and the comb blade 26e adjacent to the comb blade 26e located at the tail end (comb blade 26d shown in FIG. 2) is the last tail. It is the same as the distance γ ′ between adjacent comb blades (for example, the comb blades 26b and 26c shown in FIG. 2) at positions other than. Therefore, when the recess 31a once formed by the comb blade 26a positioned at the head in the direction of the arrow A is compressed again by the comb blade 26e positioned at the end in the direction of the arrow A, the comb blade 26e positioned at the end Since the surface in the direction of arrow A contacts the side wall surface of the recess 31a, the side wall surface of the recess 31a can be prevented from falling in the direction opposite to the direction of arrow A.

  The comb blade 26e located at the rear end has a dimension in a direction perpendicular to the direction of the arrow A even if the width α in the direction of the arrow A is the same as the width β of the other comb blade 26. If it is smaller than the dimension in the direction perpendicular to the direction of the arrow A of 26, the concave portion 31a once formed by the comb blade 26a positioned at the head is positioned at the tail when compressed again by the comb blade 26e positioned at the tail. The comb blade 26e to be cut does not cut a part of the recess 31a in the direction orthogonal to the direction of the arrow A, and the shape of the recess 31a is less likely to be lost. Further, the comb blade 26e located at the end has a width α in the direction of the arrow A smaller than the width β of the other comb blade 26 in the direction of the arrow A, and the dimension in the direction orthogonal to the direction of the arrow A is the other. The size of the comb blade 26 may be smaller than the dimension in the direction orthogonal to the direction of the arrow A. Further, the width α of the comb blade 26e in the direction of the arrow A is not limited to a case where the width α is constant in the length direction of the comb blade 26e. FIG. 4 is a front view of another punch 21a used in the carrier tape manufacturing apparatus 1 according to Embodiment 1 of the present invention. The comb blade 26 e shown in FIG. 4 gradually increases in width in the direction of arrow A from the surface for compressing the base material 3 to the root of the comb blade 26.

  The specific example of the dimension of the punch 21 is shown. The other comb blade 26 has a width β of 0.59 mm in the direction of the arrow A on the surface for compressing the substrate 3 and a dimension in the direction orthogonal to the direction of the arrow A of 1.10 mm. The comb blade 26e located at the end has a width α in the direction of arrow A on the surface for compressing the base material 3 of 0.49 mm, and a dimension in a direction orthogonal to the direction of arrow A is 1.10 mm. Moreover, the length of the comb blade 26 (the length from the surface which compresses the base material 3 to the root of the comb blade 26) is 5.00 mm.

  As described above, the carrier tape manufacturing apparatus 1 according to Embodiment 1 of the present invention has the comb positioned at the end in the direction of arrow A (the direction in which the punch 21 moves relative to the conveyance direction of the base material 3). Since the blade 26e has a smaller surface area for compressing the substrate 3 than the other comb blades 26, the recess 31a once formed by the comb blade 26a located at the head is the comb blade 26e located at the tail. When the compression is performed again, the comb blade 26e located at the end does not cut a part of the recess 31a, and the shape of the recess 31a is less likely to be lost. In addition, as shown in FIG. 3, it is not limited to the case where one side surface of the comb blade 26e located at the end does not contact the recess 31a, and the other side surface does not contact the recess 31a. Also good.

(Embodiment 2)
The punch used in the carrier tape manufacturing apparatus 1 according to Embodiment 2 of the present invention does not change the width in the direction of the arrow A of the comb blade located at the end or the dimension in the direction orthogonal to the direction of the arrow A. Next, a description will be given of a configuration that can reduce the risk of breaking the shape of the recess when the recess once formed with the comb blade positioned at the top is compressed again with the comb blade positioned at the tail. FIG. 5 is a front view of a punch used in the carrier tape manufacturing apparatus 1 according to Embodiment 2 of the present invention. Since the configuration of the carrier tape manufacturing apparatus 1 other than the punch 51 is the same as the configuration of the carrier tape manufacturing apparatus 1 according to the first embodiment, detailed description thereof is omitted.

The punch 51 can be attached to the upper die 2 by holding the base 53 with the punch holder 22. The upper mold 2 may have a configuration in which a plurality of punches 51 each having a plurality of comb blades 52 arranged in a line are held by the punch holder 22. A comb blade 52e located at the end of the direction of arrow A (the direction in which the punch 51 moves relative to the conveyance direction of the substrate 3) chamfers one side 54 of the surface on which the substrate 3 is compressed. Therefore, when the recess 31 once formed with the comb blade 52a positioned at the head is compressed again with the comb blade 52e positioned at the tail, at least the surface of the base 3 of the comb blade 52e positioned at the tail is compressed. One side does not scrape a part of the concave portion 31, and there is little risk of breaking the shape of the concave portion 31.

  Further, the distance γ between the comb blade 52e located at the tail in the direction of arrow A and the comb blade 52e adjacent to the comb blade 52e located at the tail (comb blade 52d shown in FIG. 5) It is the same as the distance γ ′ between adjacent comb blades (for example, comb blades 52b and 52c shown in FIG. 5) at positions other than. Therefore, when the concave portion 31a once formed by the comb blade 52a positioned at the head in the direction of the arrow A is compressed again by the comb blade 52e positioned at the tail in the direction of the arrow A, the comb blade 52e positioned at the rearmost position. Since the surface in the direction of arrow A contacts the side wall surface of the recess 31a, the side wall surface of the recess 31a can be prevented from falling in the direction opposite to the direction of arrow A.

  5 is chamfered on one side 54 of the surface for compressing the base material 3. However, chamfering is not limited to one side 54 of the surface that compresses the base material 3, but the other side of the surface that compresses the base material 3 or all the sides of the surface that compresses the base material 3. There may be.

  As described above, in the configuration of the carrier tape manufacturing apparatus 1 according to Embodiment 2 of the present invention, the comb blade 52e located at the end in the direction of the arrow A is chamfered on at least one side of the surface compressing the base material 3. Therefore, when the concave portion 31 once formed by the comb blade 52a located at the head is compressed again by the comb blade 52e located at the tail, the base material 3 of the comb blade 52e located at the tail is compressed. At least one side of the surface does not cut a part of the recess, and there is little risk of breaking the shape of the recess 31.
