Abstract

The invention discloses a circulation mechanism for diode device production. A diode chip, one end, which is in contact with the diode chip, of a first copper lead, and one end, which is in contact with the diode chip, of a second copper lead are coated with an epoxy body. The circulation mechanism comprises a strip-shaped substrate, multiple material combing teeth and multiple oriented teeth. Thematerial combing teeth are arranged in the middle of the strip-shaped substrate in a slotted manner in the length direction of the strip-shaped substrate, and the oriented teeth are arranged on one side of the strip-shaped substrate in a slotted manner in the length direction of the strip-shaped substrate, so a long groove is formed between the material combing teeth and the oriented teeth. Material combing teeth separation grooves are arranged between adjacent material combing teeth. Oriented teeth separation grooves are arranged between adjacent oriented teeth. The gap between each materialcombing teeth separation groove and the corresponding oriented teeth separation groove is larger than the diameter of the first copper lead and the diameter of the second copper lead. According to the invention, welded diodes are combed up from a graphite coat and rotated for 180 degrees, and materials will not fall off, so an objective of direct loading is achieved, and circulation tools can bereduced.

Description

technical field [0001] The invention relates to the production of rectifier devices, in particular to a turnover mechanism for the production of diode devices. Background technique [0002] In the prior art, in the manufacture of diodes, materials are combed onto aluminum strips through combing strips, and then the materials on the aluminum strips are transferred to the feeding rack of the forming mold. The problem brought about by this method is to increase the turnover tools, increase labor costs, and increase the risk of damage to the product caused by a process. Contents of the invention [0003] The purpose of the present invention is to provide a turnover mechanism for the production of diode devices, which can comb the welded diodes from the graphite boat and rotate 180 degrees without material falling, so as to achieve the purpose of direct feeding , can reduce turnover tools, improve labor efficiency, reduce the process of diode turnover, and improve product yiel...
