Microwave flange sealing surface polishing device

Abstract

The invention aims at disclosing a microwave flange sealing surface polishing device. The microwave flange sealing surface polishing device comprises a locating part, a polishing part and a tail installation part, the locating part is mounted at a front end of the polishing part, the tail installation part is arranged at a rear end of the polishing part, and a center of the locating part, the center of the polishing part and the center of the tail installation part are arranged on the same horizontal line; and a surface, connected with the locating part, of the polishing part is an abrasive sand surface, and the tail installation part is mounted and fixed with an electric device. Compared with the prior art, the locating part is used for locating on a flange and preventing occurrence of accidents and poor polishing effect caused by shaking in a use procedure; the abrasive sand surface of the polishing part is arranged in a form of being perpendicular to the locating part, is closely attached on a sealing surface of a microwave flange to polish and trim the sealing surface of the flange through high-speed rotation, thus, the sealing surface of the microwave flange can be stressed uniformly, a surface area polished is smooth, and the aim of the invention is realized.

Description

technical field [0001] The invention relates to a sealing surface grinding device, in particular to a microwave flange sealing surface grinding device used for solar cell production. Background technique [0002] Solar photovoltaic power generation is one of the main ways to use solar energy at present. Because of its cleanness, safety, convenience and high efficiency, solar photovoltaic power generation has become an emerging industry that is generally concerned and focused on development by countries all over the world. Therefore, in-depth research and utilization of solar energy resources is of great significance to alleviate the resource crisis and improve the ecological environment.

Problems solved by technology

[0003] In the manufacturing process of solar cells, silicon wafers need to be coated on the back side when producing PERC cells. At present, the leakage rate of the MAIA equipment cavity with back coating has a great influence on the product quality. The installation and sealing of the quartz tube in the cavity determines the quality of the cavity. Due to the size of the leakage rate of the body, the sealing surface of the microwave flange installed with the quartz tube is often no longer flat due to the burning of the sealing ring, which cannot meet the pressure maintaining requirements of the equipment. The sealing surface needs to be processed manually. The processing speed is too slow and the effect not obvious
