Full-automatic single crystal silicon rod cutting and grinding combined processing integrated equipment and using method thereof

Abstract

The invention relates to full-automatic single crystal silicon rod cutting and grinding combined processing integrated equipment and an using method thereof, and the invention provides the full-automatic single crystal silicon rod cutting and grinding combined processing integrated equipment, which can process a round rod into a square rod by integrated processing of square cutting, corner grinding and surface grinding, so that the problems in the prior art can be solved effectively; the type and quantity of the equipment can be reduced, the area of a plant, the labor and logistics cost can besaved when the processing efficiency of the silicon rod is improved, the processing cost of the silicon rod is reduced and the size precision of the crystal rod is improved. The invention can make asquare cutting assembly and a grinding assembly work independently without interference, and the processing efficiency is improved; in addition, a square cutting grinding power head adopts a symmetrical layout, meanwhile double-sided machining is carried out, so the processing efficiency is doubled.

Description

technical field [0001] The invention relates to a fully automatic monocrystalline silicon rod squaring and grinding compound processing integrated equipment and its use method, which is suitable for the automatic processing of single crystal silicon rod squaring and grinding with high efficiency, high quality and low cost, and belongs to single crystal Silicon rod processing field. Background technique [0002] Silicon single crystal material is the most important raw material for photovoltaic power generation. In recent years, with the rapid expansion of the photovoltaic industry, the production capacity of silicon single crystal has continued to increase. Common methods for preparing silicon single crystals include Czochralski method, zone melting method and other methods, and the single crystal silicon prepared by such methods are all formed into cylindrical crystal rods. The whole monocrystalline silicon ingot prepared needs to be truncated first, and the overlong ingot...

AI Technical Summary

Problems solved by technology

In this way, the whole process requires three kinds of processing equipment with different functions, and silicon rods need to be frequently carried out manually between the equipment and clamping and positioning operations before processing.

The handling and clamping of silicon rods not only brings positioning errors but also increases the work of logistics, and the processing accuracy of the three types of equipment will affect the processing process

In general operation, in order to ensure sufficient machining allowance during grinding, a large positive dimension deviation is set during cutting, which not only wastes silicon rod material but also increases the workload of grinding processing, making the entire processing process inefficient and expensive. duration
