Apparatus for manufacturing a carrier tape and method for manufacturing a carrier tape

Abstract

PROBLEM TO BE SOLVED: To provide a device for manufacturing a carrier tape including a comb-shaped punch reducing a possibility of deforming a shape of a recess when the recess formed once by a comb blade located at a top in a direction of the relative displacement of the punch with respect to a carrying direction of a substrate is compressed again by a comb blade located at a trail end in the direction of the relative displacement of the punch with respect to the carrying direction of the substrate, and a method of manufacturing the carrier tape.SOLUTION: The device 1 for manufacturing the carrier tape includes: an upper die 2 including the punch 21 forming a plurality of recesses 31 for storing electronic components on the surface of the substrate 3; and a lower die 4 on which the substrate 3 is placed and which is fitted to the upper die 2 to compress and form the substrate 3. The punch 21 includes a plurality of comb blades 26 arranged to form a line. An area of a face compressing the substrate 3 of the comb blade 26e located at the trailing end in the direction of the relative displacement of the punch 21 with respect to the carrying direction of the substrate 3 is set smaller than those of the other comb blades 26a-26d.

Description

technical field [0001] The present invention relates to a carrier tape manufacturing device and a method for manufacturing a carrier tape, and in particular, to a carrier tape that compresses and molds a conveyed strip-shaped substrate to manufacture a concave portion for housing electronic components. The carrier tape manufacturing device and the manufacturing method of the carrier tape. Background technique [0002] In an apparatus for mounting electronic components on a circuit board, a carrier tape containing electronic components is used in order to easily supply the electronic components. Patent Document 1 discloses a conventional carrier tape manufacturing apparatus. [0003] Patent Document 1 discloses an apparatus for manufacturing a carrier tape by compression-molding a strip-shaped substrate conveyed by a cope and a drag, wherein the cope has a punch forming a carrier tape. A plurality of recesses are used to accommodate electronic components, and the above-ment...
