Abstract
The invention provides an efficient grinding and chamfering all-in-one machine. The machine comprises a base assembly, workbench assemblies, a transfer manipulator, coarse grinding assemblies, refining assemblies, a coarse barreling assembly, a fine barreling assembly, a feeding mechanism and a discharging mechanism, wherein the base assembly comprises a base and a guide rail arranged on the base,the two workbench assemblies are arranged, the two workbench assemblies are slidably arranged at the two ends of the base correspondingly, the transfer manipulator is arranged in the middle of the base, the two coarse grinding assemblies and the two refining assemblies are arranged, and are each oppositely arranged on the two sides of the base, the coarse barreling assembly is arranged on one side of the base and located between the coarse grinding assemblies and the transfer manipulator, the fine barreling assembly is arranged on one side of the base and located between the refining assemblies and the transfer manipulator, and the feeding mechanism and the discharging mechanism are the same in structure and are arranged at the two ends of the base correspondingly. The machine can conductintegrated polishing on arcs, corners and surfaces of polysiliconsingle of different specifications, a coarse grinding procedure and a refining procedure do not interfere with each other, the idle time of the machine is shortened, the machine capacity is high, and the machining period is short.
Description
technical field
[0001] The invention relates to the technical field of silicon rod processing equipment, in particular to a high-efficiency grinding and pouring integrated machine. 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 components. The purity of polysilicon used to produce photovoltaic silicon wafers must be above 6N level, otherwise the performance of photovoltaic cells will be greatly negatively affected. In the photovoltaic industry, in order to remove defects in the processing of silicon rods and reduce the scrap rate, it is necessary to grind silicon rods after prescription and before slicing. At present, the grinding ...
