Automatic quality classifying device and method for solar polycrystalline silicon chips

Abstract

The invention provides an automatic quality classifying device and method for solar polycrystalline silicon chips, and belongs to the technical field of solar energy. The problem that existing solar polycrystalline silicon chips are not prone to being classified is solved. The automatic quality classifying device for the solar polycrystalline silicon chips comprises a device main body, a detectingdevice and an arranging device; the detecting device is arranged at the left end of the device main body and electrically connected with the device main body; a machine top cover is arranged at the top end of the detecting device and fixedly connected with the detecting device; the arranging device is arranged at the right end of the device main body and electrically connected with the device main body; and a storage cabinet is arranged at the right end of the arranging device and connected with the arranging device in a penetrating mode. The automatic quality classifying device for the solarpolycrystalline silicon chips integrates detecting and classifying, thus the two working procedures of detecting and classifying are completed simultaneously, and the working efficiency of the automatic quality classifying device is greatly improved.

Description

Technical field [0001] The invention relates to the technical field of quality detection and classification, in particular to an automatic quality classification device and a classification method for solar polycrystalline silicon wafers. Background technique [0002] Polycrystalline silicon wafer is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged into many crystal nuclei in the form of a diamond lattice. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to crystallize into polysilicon , Polycrystalline silicon wafers are mostly used in electronics and solar power generation. They are used as raw materials in the solar energy industry chain. They are used to cast ingots or pull monocrystalline silicon rods, cut into silicon wafers, and produce solar panels. [0003] Nowadays, the quality classification of polycrystalline silicon waf...
