Silicon chip kit platform having pitching function

Abstract

The invention relates to a silicon chip box platform with pitching function, which comprises two positioning shafts, a protecting plate frame is connected to the two positioning shafts, the protecting plate frame is connected with the front end of the bottom of a turning plate by a rotating shaft mechanism, a fixing plate is connected to the two positioning shafts which are arranged in the protecting plate frame, a crank connecting rod mechanism which is connected with a driving device is connected to the fixing plate, the output end of the crank connecting rod mechanism is connected with the rear end of the bottom of the turning plate through a rotating block, and the top of the turning plate is connected with a silicon chip box. When a crank of the crank connecting rod mechanism swings in a reciprocating and intermittent mode at the range of 0 to 180 degrees, the silicon chip box is connected with the crank to swing in a pitching mode. The crank connecting rod mechanism which is taken as a core mechanism of the invention and the rotating shaft mechanism have simple and reasonable structures, not only can realize automatic pitching, but also can realize stable pitching, thereby solving the problems in the prior art.

Description

technical field [0001] The invention relates to a support platform, in particular to a silicon wafer box platform with pitching function. Background technique [0002] The silicon wafers currently used in semiconductor manufacturing process equipment must be placed in a special silicon wafer box, each silicon wafer box can hold 25 silicon wafers (international standard), and the silicon wafer box is placed on the platform of the process equipment , the silicon wafers are picked and placed from the silicon wafer box on the platform by a special manipulator. At present, there are fixed silicon wafer box platform and silicon wafer box platform with pitching function that are widely used in the world. The silicon wafer box platform with pitching function has only appeared in recent years. It has the following advantages: 1. The silicon wafer box platform can be placed at a certain elevation angle. When the operator takes and places the silicon wafer box, it is relatively stable...

AI Technical Summary

Problems solved by technology

However, the structure of the current silicon wafer box platform with pitch function is complex, and it is prone to vibration when the pitch state changes, and then drives the silicon wafer to vibrate together. This phenomenon is unacceptable to users.
