Problems solved by technology

In the previous crystal silicon squaring, grinding and pouring all-in-one machine, the transfer of silicon rods between the squaring mechanism and the grinding and polishing mechanism used a manipulator. The manipulator has the characteristics of convenient transfer, but due to the limitation of equipment space and other factors, multiple manipulators often Therefore, generally only one manipulator is set between the squaring mechanism and the grinding and polishing mechanism, so that a manipulator can only hold a silicon rod at the squaring mechanism or at the grinding mechanism. Grinding, when one of the grinding mechanism or the squaring mechanism is working, the other is in an idle state, which restricts the utilization rate of the equipment and affects the processing efficiency of the silicon rod. After the prescription is completed, when the silicon rods are transported to the grinding and polishing mechanism for grinding and polishing, the silicon rods need to be clamped twice. The secondary clamping will easily increase the grinding allowance of the silicon rods and prolong the processing time of the silicon rods. Therefore, how to reduce the number of clamping times in the processing of silicon rods and improve the processing efficiency of silicon rods is a problem we need to solve

Description

technical field [0001] The invention belongs to the technical field of crystal silicon processing equipment, and in particular relates to an all-in-one machine for square cutting and grinding of silicon rods. Background technique [0002] Photovoltaic power generation is one of the most important clean energy sources with great development potential. The key factors restricting the development of photovoltaic industry are low photoelectric conversion efficiency on the one hand and high cost on the other hand. Photovoltaic silicon wafers are the basic material for the production of solar cells and modules. The actual production of a single silicon rod involves processes such as preparation, edge trimming, surface grinding, polishing, chamfering, slicing, battery slices, and components. In the previous crystal silicon squaring, grinding and pouring all-in-one machine, the transfer of silicon rods between the squaring mechanism and the grinding and polishing mechanism used a ...
