Silicon rod cutting and grinding all-in-one machine and silicon rod cutting and grinding method

Abstract

The invention discloses a silicon rod cutting and grinding all-in-one machine and a silicon rod cutting and grinding method.The silicon rod cutting and grinding all-in-one machine comprises a cutting device and a grinding device, the cutting device comprises a first cutting unit, a first distance adjusting unit, a second cutting unit and a second distance adjusting unit, and the first cutting unit comprises two orthogonal first cutting wire saws; the second cutting unit comprises two orthogonal second cutting fretsaws, and the cutting positions of the two orthogonal first cutting fretsaws are adjusted through the first distance adjusting unit so as to adjust the cutting space formed by the two orthogonal first cutting fretsaws. And the second distance adjusting unit is used for adjusting the cutting positions of the two orthogonal second cutting fretsaws so as to adjust the cutting space formed by the two orthogonal second cutting fretsaws, so that based on the silicon rod cutting and grinding all-in-one machine, the integrated operation of multiple processes of squaring and grinding of the silicon rod can be completed, the production efficiency and the quality of product processing operation are improved, and the production cost is reduced. And cutting spaces formed by the cutting wire saws can be adjusted to adapt to silicon rods with different specifications and sizes.

Description

technical field [0001] The present application relates to the technical field of silicon workpiece processing, in particular to a silicon rod cutting and grinding integrated machine and a silicon rod cutting and grinding method. Background technique [0002] At present, with the attention and opening of the society to the utilization of green and renewable energy, the field of photovoltaic solar power generation has received more and more attention and development.
