Abstract

The invention discloses a multistage monocrystalline silicon square rod surface grinding device, which comprises an engine base and a horizontal working turnplate arranged on the engine base through a vertical bearing. The working turnplate is connected with a transmission device; equant positions of the upper surface of the working turnplate is provided with a plurality of sets of silicon rod positioning units respectively; the lateral surfaces of the engine base are fixedly connected with the plurality of grinding units having the same structure; each grinding unit comprises an upright post; the upright post is connected with a sliding seat through a precision linear motion component; the precision linear motion component is connected with a precision motor; the sliding seat is also provided with a cooling water pipe and an electric main shaft vertically arranged; and the lower end of the electric main shaft is provided with a grinding wheel. The device can quickly assemble the silicon rod, achieves multistage, circulatory and continuous operations of coarse grinding, fine grinding and polishing of the plurality of rods, and improves machining accuracy and production efficiency.

Description

technical field [0001] The invention belongs to the technical field of fine processing equipment for silicon rods, and relates to a multi-station single crystal silicon square rod surface grinding device. Background technique [0002] Monocrystalline silicon is the main raw material for manufacturing solar cells. Before the square monocrystalline silicon rods are made into solar cells, in order to ensure the consistency of the size of solar cells and improve the yield of silicon rods when slicing, it is necessary to Four planes are ground to meet certain dimensional accuracy and surface roughness requirements. The surface grinding device currently used is mainly modified by a vertical milling machine, and the milling cutter is changed to a grinding wheel to grind the four planes of the square silicon rod. Only one silicon rod can be processed at a time, and the installation and alignment takes a long time. The work efficiency is low, and it cannot meet the needs of precisio...
