Therefore, when the recessed portion temporarily formed by the comb knife located at the forefront is recompressed using the comb knife located in the last row, it is located in the last column. The comb does not cut a part of the concave portion in a direction orthogonal to the direction in which the perforator is relatively moved with respect to the conveying direction of the substrate, so that the shape of the concave portion is less likely to be deformed.

In order to achieve the above object, a carrier tape manufacturing apparatus according to a fourth aspect of the present invention is a carrier tape for compression-molding a conveyed tape-shaped substrate, comprising: a first die having a puncher, wherein the puncher is a surface on one side of the substrate forms a plurality of recesses for accommodating the electronic component; and a second mold on which the substrate is placed and fitted to the first mold for compression molding; the perforator has an arrangement a plurality of combs in a row; the comb in the last row of the direction in which the perforator moves relative to the direction of transport of the substrate will at least one side chamfer the surface on which the substrate is compressed.

The belt-shaped base material 3 is conveyed at a predetermined pitch in a direction perpendicular to the paper surface of FIG. 1, and the base material 3 to be conveyed is compression-molded by the piercer 21 to form the concave portion 31. The stripper plate 24 is a member that presses the base material 3 so that the base material 3 does not move when the puncher 21 is pulled out from the base material 3 after the base material 3 is compressed by the piercer 21 . Further, a stroke end block 25 is provided on the upper mold 2, and the stroke end block 25 stabilizes the lower fulcrum of the upper mold 2 when fitted with the lower mold 4 to determine the amount of penetration of the punch 21 into the substrate 3. The stroke end block 25 is not limited to the case of being provided in the upper mold 2, and may be provided in the lower mold 4.

The lower mold 4 has a template 41 on which the substrate 3 is placed. The template 41 has a groove 42 on the surface on which the substrate 3 is placed. The material of the punch 21 and the template 41 is, for example, a super hard alloy.

Fig. 2 is a front elevational view of the piercer 21 used in the carrier tape manufacturing apparatus 1 according to the first embodiment of the present invention. The punch 21 shown in Fig. 2 has a comb shape in which five comb blades 26 are connected at the base portion 27. The comb (comb-shaped blade) 26 of the punch 21 and the base 27 are formed integrally. The perforator 21 can be attached to the upper mold 2 by holding the base portion 27 using the piercer holder 22. The upper mold 2 may also be a structure in which a plurality of perforators 21 are arranged and held by a perforator holder 22 having a plurality of comb blades 26 arranged in a line. The last comb comb 26e located in the direction of the arrow A (the direction in which the perforator 21 is relatively moved with respect to the conveyance direction of the substrate 3) is reduced in comparison with the other combs 26 (26a to 26d). 3 The area of the surface to be compressed. In particular, the comb blade 26e reduces the width α (<width β) of the surface on which the substrate 3 is compressed in the direction of the arrow A as compared with the other comb blades 26.

3 is a schematic view for explaining a state in which the concave portion 31 temporarily formed on the surface of the base material 3 is compressed again by the piercer 21 of the carrier tape manufacturing apparatus 1 according to the first embodiment of the present invention. As shown in FIG. 3, when the comb 26e of the last row in the direction of the arrow A is used, the comb of the forefront in the direction of the arrow A (the direction in which the perforator 21 is relatively moved with respect to the conveyance direction of the substrate 3) is combed. When the concave portion 31a temporarily formed by the blade 26 is compressed again (double perforation), since the comb blade 26e located in the last row is smaller than the other comb blades 26, the area of the surface on which the base material 3 is compressed is reduced, and therefore, The comb knives 26e of the last row do not cut a part of the recess 31a, so that the possibility of deforming the shape of the recess 31a is small. In particular, the comb blade 26e reduces the width α (<width β) of the surface on which the substrate 3 is compressed in the direction of the arrow A as compared with the other comb blades 26, and therefore, when the comb knife 26e at the last end is used When the concave portion 31a temporarily formed by the comb knife 26a located at the forefront is compressed again, the comb knife 26e at the rear end does not cut a part of the concave portion 31a in the direction of the arrow A, thereby making it possible to deform the shape of the concave portion 31a. Smaller. Here, in the case where the base material 3 is compressed again by using the comb blade 26, the case where the comb blade 26 is fitted to the temporarily formed concave portion 31 is also included.

Further, the distance γ between the comb 26e in the last row in the direction of the arrow A and the comb 26 (the comb 26d shown in Fig. 2) adjacent to the comb 26e in the last row is outside the last column. The distance γ' between the adjacent combs (e.g., the combs 26b, 26c shown in Fig. 2) is equal. Therefore, when the concave portion 31a temporarily formed by the comb 26a in the forefront of the arrow A direction is compressed again using the comb 26e in the last row in the direction of the arrow A, since the comb 26e located in the last row is leaned Since the surface on the direction of the arrow A is in contact with the side wall surface of the recess 31a, it is possible to prevent the side wall surface of the recess 31a from falling in the opposite direction to the arrow A direction.

Even if the width α of the comb blade 26e in the last row in the direction of the arrow A is the same as the width β of the other comb blades 26, the dimension in the direction orthogonal to the direction of the arrow A is made more positive than the direction of the arrow A of the other comb 26. When the size in the direction of intersection is small, when the concave portion 31a temporarily formed by the comb blade 26a located at the forefront is compressed again using the comb knife 26e located in the last row, the comb knife 26e located in the last row is not in the arrow A A part of the concave portion 31a is cut in the direction orthogonal to the direction, so that the shape of the concave portion 31a is less likely to be deformed. Further, the width α of the comb blade 26e in the last row in the direction of the arrow A may be made smaller than the width β of the other comb blades 26 in the direction of the arrow A, and the dimension in the direction orthogonal to the direction of the arrow A may be made larger than the other. The size of the comb blade 26 in the direction orthogonal to the direction of the arrow A is small. Further, the width α of the comb blade 26e in the direction of the arrow A is not limited to the case where it is constant in the longitudinal direction of the comb blade 26e. Fig. 4 is a front elevational view showing another piercer 21a used in the carrier tape manufacturing apparatus 1 according to the first embodiment of the present invention. The width of the comb blade 26e shown in Fig. 4 in the direction of the arrow A gradually increases from the surface on which the base material 3 is compressed to the root portion of the comb blade 26.

A specific example of the size of the punch 21 is shown. The width β of the surface of the other comb 26 that compresses the base material 3 in the direction of the arrow A is 0.59 mm, and the dimension in the direction orthogonal to the direction of the arrow A is 1.10 mm. The width α of the surface of the comb blade 26e that is compressed in the last row on the substrate 3 in the direction of the arrow A is 0.49 mm, and the dimension in the direction orthogonal to the direction of the arrow A is 1.10 mm. Further, the length of the comb 26 (the length from the surface compressed with respect to the substrate 3 to the root of the comb 26) was 5.00 mm.

As described above, in the tape carrier manufacturing apparatus 1 according to the first embodiment of the present invention, the comb comb 26e of the last row in the direction of the arrow A (the direction in which the perforator 21 moves relative to the conveyance direction of the substrate 3) and the like Compared with the comb blade 26, the area of the surface on which the substrate 3 is compressed is reduced, and therefore, when the concave portion 31a temporarily formed by the comb blade 26a located at the forefront is compressed again using the comb blade 26e located in the last row The comb knife 26e located in the last row does not cut a part of the recess 31a, so that the possibility of deforming the shape of the recess 31a is small. As shown in FIG. 3, it is not limited to the case where one side surface of the comb blade 26e located in the last row does not contact the recessed part 31a, and the other side surface may not contact with the recessed part 31a.

(Embodiment 2)

The structure of the punch used in the carrier tape manufacturing apparatus 1 according to the second embodiment of the present invention will be described. In the configuration of the punch, the width of the comb knife in the last row in the direction of the arrow A or the direction of the arrow A is not changed. The size in the orthogonal direction is less likely to deform the shape of the concave portion when the concave portion temporarily formed by the comb knife located at the forefront is compressed again using the comb knife located in the last row. Fig. 5 is a front elevational view of the piercer used in the carrier tape manufacturing apparatus 1 according to the second embodiment of the present invention. Since the configuration of the carrier tape manufacturing apparatus 1 other than the piercer 51 is the same as that of the carrier tape manufacturing apparatus 1 of the first embodiment, a detailed description thereof will be omitted.

The punch 51 shown in Fig. 5 has a comb shape in which five comb blades 52 are connected at the base portion 53. The comb 52 and the base 53 of the punch 51 are formed integrally. The perforator 51 can be attached to the upper mold 2 by holding the base 53 with the piercer holder 22. The upper mold 2 may also be a structure in which a plurality of punchers 51 are arranged and held using a piercer holder 22 having a plurality of comb blades 52 arranged in a line. The comb 52e of the last row in the direction of the arrow A (the direction in which the perforator 51 moves relative to the conveyance direction of the base material 3) deviates the one side 54 of the surface of the compression base material 3. Therefore, when the concave portion 31 temporarily formed by the comb 52a located at the forefront is compressed again by using the comb 52e located in the last row, at least one of the faces of the comb 52e of the last row that compresses the substrate 3 is compressed. A part of the recess 31 is not cut, so that the possibility of deforming the shape of the recess 31 is small.

Further, the distance γ between the comb 52e in the last row in the direction of the arrow A and the comb 52 (the comb 52d shown in Fig. 5) adjacent to the comb 52e in the last row is outside the last column. The distance γ' between the adjacent combs (e.g., the combs 52b, 52c shown in Fig. 5) is equal. Therefore, when the concave portion 31a temporarily formed by the comb 52a in the forefront of the arrow A direction is compressed again using the comb 52e in the last row in the direction of the arrow A, since the comb 52e located in the last row is leaned Since the surface on the direction side of the arrow A is in contact with the side wall surface of the recess 31a, it is possible to prevent the side wall surface of the recess 31a from falling in the opposite direction to the arrow A direction.

The comb 52e in the last row shown in Fig. 5 is chamfered on one side 54 of the surface of the compressed substrate 3. However, the corner is not limited to one side 54 of the surface on which the base material 3 is compressed, and may be the other side of the surface on which the base material 3 is compressed or the other side of the surface on which the base material 3 is compressed.

As described above, in the configuration of the carrier tape manufacturing apparatus 1 according to the second embodiment of the present invention, since at least one side of the surface of the compressed substrate 3 is chamfered by the comb 52e in the last row in the direction of the arrow A, when When the concave portion 31 temporarily formed by the comb 52a located at the forefront is compressed again by the comb 52e at the last end, at least one side of the surface of the final comb comb 52e that compresses the base material 3 does not cut the recess. A part of it, so that the shape of the recess 31 is less likely to be deformed.
