A positioning device for semiconductor device welding

Abstract

The invention discloses a positioning device for semiconductor device welding, which comprises a material platform, an extension plate, a translation mechanism, a loading and unloading mechanism, a limit mechanism and an adsorption mechanism. The outer side of the material platform is provided with a through groove, and both sides of the material platform are fixed. There is an extension plate connected, and a limit mechanism is set in the middle of the material table. The translation mechanism includes a track rack, a guard plate, a connecting plate, a No. 1 servo motor, a drive rod, a drive gear and a shift fork. The track rack is fixedly connected to the extension plate. On the upper side, the upper side of the track rack is equipped with a guard plate, and a connecting plate and a driving rod are arranged between the two guard plates. The connecting plate and the guard plate are fixedly connected. The present invention has compact structure, reasonable structural design and high degree of automation. In specific use, the translation mechanism can move the horizontal cover plate in the loading and unloading mechanism to reciprocate. The loading and unloading mechanism cooperates with the adsorption mechanism to realize the handling process of semiconductor devices. The limit mechanism can accurately move semiconductor devices from four directions. position.

[0002] A semiconductor device is an electronic device whose conductivity is between a good conductor and an insulator. It uses the special electrical characteristics of semiconductor materials to complete specific functions. It can be used to generate, control, receive, transform, amplify signals and perform energy conversion. The semiconductor of semiconductor devices The material is silicon, germanium or gallium arsenide, which can be used as rectifiers, oscillators, light emitters, amplifiers, photometers and other equipment. In order to distinguish them from integrated circuits, they are sometimes called discrete devices. Most of the two-terminal devices The basic structure is a PN junction. When processing semiconductor devices, manual loading and unloading and positioning operations are required, which cannot meet the requirements of modern production, and the safety factor of manual operation is low.
