Method for grinding solar silicon rod

Abstract

The invention provides a method for grinding a solar silicon rod, which is used for grinding the solar silicon rod with four surfaces to be ground, and mainly provides an annular rotary table with four circular grinding areas. The four circular grinding areas are blocked in the rotating direction of the annular rotary table, so that when the annular rotary table is directionally rotated, the circular grinding areas are forced to autorotate at the set position; grinding fluid or a grinding cushion is arranged on the annular rotary table; the solar silicon rod is arranged in the circular grinding areas, and the surfaces to be ground are contacted with the grinding fluid or the grinding cushion; when the circular grinding areas autorotate, the solar silicon rod is driven to rotate to make the surfaces to be ground and the grinding fluid or the grinding cushion relatively move so as to grind the surfaces. By the method, the problem that the silicon rod is easily scratched when ground in the prior art is solved, so that the product qualification rate and the operation efficiency of equipment are improved.

Description

Technical field [0001] The invention relates to a solar silicon material grinding technology, in particular to a solar silicon rod grinding method. Background technique [0002] With the increasing depletion of non-renewable energy, the development of renewable energy is gradually being valued. Solar energy, as an unlimited energy and clean energy, has naturally become the top priority in the field of new energy. For this reason, people have invested in this field. A large amount of manpower and material resources have been researched and developed, and at the same time it has promoted the development of related industries, such as the production and processing of silicon materials as raw materials for solar cells. [0003] Solar cells are made of many solar silicon wafers glued on a metal plate coated with an anti-corrosion conductive layer on the surface with conductive adhesives, and directly convert light energy into electrical energy through photoelectric or photochemical effe...

AI Technical Summary

Problems solved by technology

In addition, due to the presence of scratches on the grinding surface of the silicon rod, the sliced ​​slices are easily broken from the scratches in the subsequent slicing operation, which leads to a large number of defective products, which not only reduces the quality of the product, but also waste of product cost
