Silicon chip thinning equipment for monocrystalline silicon cell production technology

Abstract

The invention belongs to the technical field of monocrystalline silicon cell production, and especially relates to silicon chip thinning equipment for the monocrystalline silicon cell production technology. A to-be-solved technical problem is to provide the silicon chip thinning equipment which is high in thinning speed, is simple in operation and is uniform in reduced thickness. In order to solve the above problem, the invention provides the silicon chip thinning equipment, and the silicon chip thinning equipment comprises a first rotating shaft, a worm gear, a flat belt, a second rotating shaft, a first bearing seat, a big belt pulley, a gear, a first installation seat, a rack, a sliding block, a sliding rail, and a right frame. The right end of the top of the bottom plate is provided with the right frame through welding, and the upper part of the left side of the right frame is connected with a sliding rail in a mode of bolt connection. The equipment is quick in thinning speed, is simple in operation, is uniform in thinning thickness, plays an important role in thinning, also improves the work efficiency, and is high in safety.

Description

Technical field [0001] The invention belongs to the technical field of monocrystalline silicon battery production, and in particular relates to a silicon wafer thinning device used in a monocrystalline silicon battery production process. Background technique [0002] Monocrystalline silicon solar cell is currently the fastest developed solar cell. Its composition and production process have been finalized, and its products have been widely used in space and ground facilities. This solar cell uses high-purity monocrystalline silicon rods as raw materials, with a purity requirement of 99.999%. In order to reduce production costs, solar cells used on the ground use solar-grade monocrystalline silicon rods, and material performance indicators have been relaxed. Some can also use the head and tail materials and waste monocrystalline silicon materials processed by semiconductor devices, and make them into monocrystalline silicon rods for solar cells after redrawing. Cut the monocryst...
