Abstract

The invention discloses a high-efficiency silicon wafer degumming device. The high-efficiency silicon wafer degumming device comprises a fixed annular rack, a movable annular rack, a degumming support, a first degumming groove, a second degumming groove and a filtration groove, wherein the movable annular rack which can rotate is arranged at the bottom of the fixed annular rack, five telescopic rods which are independent to one another are arranged at the bottom of the movable annular rack, the degumming support is fixedly arranged at the bottoms of the telescopic rods and comprises a top plate, vertical posts, U-shaped frames and a baffle plate, and the first degumming groove, the second degumming groove and the filtration groove are arranged under the movable annular rack. The degumming support is connected with the movable annular rack by the telescopic rods, so that the degumming support can automatically pass through the first degumming groove, the second degumming groove and the filtration groove, the degumming device is convenient to use, and the degumming efficiency is improved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of polysilicon production, in particular to the technical field of silicon wafer degumming tanks. [0003] 【Background technique】 [0004] The cleanliness of the silicon wafer surface is a key factor affecting the silicon wafer yield and cell conversion efficiency. In order to obtain silicon wafers with high cleanliness, silicon wafers often need degumming cleaning and fine cleaning after wire cutting. The degumming effect of the existing degumming device is not ideal, and a large amount of residue is likely to be generated after the degumming is completed, which is not conducive to subsequent cleaning. [0005] 【Content of invention】 [0006] The object of the present invention is to solve the problems in the prior art, and propose a high-efficiency silicon wafer degumming device, which can improve the degumming effect of silicon wafers and improve the degumming efficiency at the same time. [00...
