Abstract

The invention discloses a turnover device applied to the manufacture of an axial type diode. The turnover device includes a bar-shaped substrate, a plurality of material combing teeth and a plurality of orientation teeth, wherein the plurality of material combing teeth are positioned at the middle of the bar-shaped substrate and straightly arranged along the length direction, the plurality of orientation teeth are positioned on one side of the bar-shaped substrate and straightly arranged along the length direction, and thereby a long slot is formed between the plurality of material combing teeth and the plurality of orientation teeth, a material combing tooth slot is formed between the two adjacent material combing teeth, a material combing tooth slot is formed between the two adjacent orientation teeth, and the spacing of the material combing tooth slots is more than the diameters of a first copper lead and a second copper lead; the material combing teeth and the orientation teeth are positioned on the same side of the bar-shaped substrate and arranged oppositely, and a stepped surface is arranged on one side of the long slot and between the material combing teeth and the bar-shaped substrate. According to the turnover device provided by the invention, the purpose of directly loading is achieved, the turnover tools can be reduced, the work efficiency is improved, the turnover process of the diode is reduced, and the product yield is improved.

Description

technical field [0001] The present invention relates to the production of rectifying devices, in particular to a turnaround device for the manufacture of axial type diodes. 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 object of the present invention is to provide a trench type Schottky semiconductor device, which improves the reliability of the device, the potential line density will be reduced at the top of the trench, and the device forward voltage drop Both the loss of the device and the device are reduced, and the leakage of the device is further reduced when the devic...
