Polishing device for photovoltaic sheet machining

Abstract

The invention provides a polishing device for photovoltaic sheet machining, and relates to the technical field of polycrystalline silicon machining, the polishing device comprises a base, the top of the base is of a flat plate structure; the L-shaped frame is fixedly arranged on one side of the top of the base, and a telescopic air rod is fixedly arranged at the bottom of the front end of the L-shaped frame; a middle shaft is fixedly arranged in the middle of the bottom of the square table, the bottom of the middle shaft is rotationally arranged at the top of the base in cooperation with a conical roller bearing, and the middle shaft is aligned with the circle center of the telescopic air rod; a hexagonal shaft and a grinding wheel provide a machining function capable of rapidly and automatically grinding and providing a flanging effect, a motor is started to drive the hexagonal shaft to rotate, a moving seat can be pushed to approach a silicon wafer, the grinding wheel is driven to rotate, grinding can be guaranteed, a rack drives a limiting ring and a square table to rotate and change edges in the reset process, automation is achieved, and the machining efficiency is improved. The problem that an existing edge grinding device lacks the machining functions of rapidly and automatically grinding and providing the flanging effect is solved.

Description

technical field [0001] The invention relates to the technical field of polysilicon processing, in particular to a polishing device for processing photovoltaic sheets. Background technique [0002] Polysilicon, a form of elemental silicon, is used to make photovoltaic silicon wafers. It is generally made into a square sheet structure, which is uniformly cut with a slicer, and then a coating that absorbs sunlight is added to the photovoltaic surface. After setting the coating, there may be edges. Side-dipped silicon wafers, which hinder splicing, are usually scraped with a tool. [0003] However, at present, the processing of photovoltaic sheets is mainly realized by tools or edge grinding machines, which lack the processing function that can quickly and automatically grind and provide flanging effect. It is not convenient to quickly remove the alignment structure during edge grinding, which is not conducive to efficient automatic grinding. SUMMARY OF THE INVENTION [0004]...
