Silicon rod grinding machine and silicon rod grinding method

Abstract

The invention provides a silicon rod grinding machine and a silicon rod grinding method. A rough grinding device and a fine grinding device of the silicon rod grinding machine are arranged at a first machining area position and a second machining area position of a silicon rod machining platform respectively, and a first transfer device and a second transfer device which simultaneously penetrate through the first machining area position and the second machining area position are arranged; and a silicon rod clamp and a driving mechanism are respectively arranged for the first transfer device and the second transfer device, and the first transfer device, the second transfer device, the rough grinding device and the fine grinding device are controlled in a coordinated manner so that the rough grinding device and the fine grinding device of the silicon rod grinding machine can be in a working state at the same time. On the basis that the size specification and cost of the silicon rod grinding machine are kept, the grinding machining efficiency is improved to two times, the grinding operation time consumption is reduced, and the economic benefits are improved.

Description

technical field [0001] The present application relates to the technical field of silicon workpiece processing, in particular to a silicon rod grinding machine and a silicon rod grinding method. Background technique [0002] At present, with the society's attention and openness to the utilization of green and renewable energy, the field of photovoltaic solar power generation has received more and more attention and development. In the field of photovoltaic power generation, the usual crystalline silicon solar cells are made on high-quality silicon wafers, which are cut by multi-wire sawing and subsequent processing from pulled or cast silicon ingots. [0003] The production process of existing silicon wafers, taking monocrystalline silicon products as an example, generally, the general operation process can include: first use the silicon rod cutting machine to cut the original long silicon rod to form multiple short silicon rods; Finally, use the silicon rod squarer to squar...
