Description

Side skin discharging device and double-station squaring equipment applying same Technical Field The invention relates to the technical field of crystal silicon processing equipment, in particular to an edge skin blanking device and double-station squaring equipment using the same. Background Monocrystalline silicon is used as a key base material in the modern semiconductor industry and photovoltaic industry, and plays an irreplaceable role in the fields of integrated circuit manufacture, solar cell production and the like. In the production flow of monocrystalline silicon, the processing of a cylindrical monocrystalline silicon rod into a square rod with a specific cross-sectional shape is an important link, and the processing can better meet the requirements of the subsequent processes such as battery assembly manufacturing and the like. However, conventional monocrystalline silicon rod formulation techniques and equipment have a number of challenges to be addressed. First, conventional single crystal silicon rod squaring equipment mostly adopts a single-station operation mode. In this mode, the apparatus can perform the squaring process on only one single crystal silicon rod at a time, and can start processing the next single crystal silicon rod after the squaring of one single crystal silicon rod is completed. The sequential processing mode makes the overall processing efficiency of the equipment extremely low, and the increasing production demands of the current market can not be met far. With the rapid development of the photovoltaic industry and the continuous rising of the demand of the semiconductor industry for monocrystalline silicon, the improvement of the processing efficiency of the monocrystalline silicon rod evolution has become an urgent demand for industry development. Secondly, in the aspect of edge skin treatment, a large amount of edge skin waste is generated in the process of opening the monocrystalline silicon rod. The traditional edge skin cleaning mode is operated manually after the equipment is stopped. The mode can not only lead to frequent interruption of the production flow and seriously affect the production efficiency, but also has the advantages of high labor intensity of manual cleaning, easy influence of human factors on the cleaning effect and incapability of ensuring the timeliness and stability of cleaning. In addition, in the process of taking out the edge skin, the edge skin is easy to be adsorbed on the crystal bar due to reasons such as cooling liquid used in the cutting process, so that the clamping jaw is difficult to take out the edge skin smoothly, and the difficulty and time cost for cleaning the edge skin are further increased.
