Squaring method for silicon ingot

Abstract

The invention provides a squaring method for a silicon ingot, which comprises the following steps: laying an isolating membrane on one surface of a crystal support, which is provided with gaps, wherein the isolating membrane is used for isolating the crystal support from the silicon ingot to be squared; spraying polystyrene foam on the isolating membrane and filling the polystyrene foam into the gaps in the foaming process; placing the silicon ingot on the crystal support and enabling the polystyrene foam to be adhered to the silicon ingot; placing the crystal support supporting the silicon ingot in a cutting chamber of a squarer to carry out squaring on the silicon ingot. In the squaring method for the silicon ingot, which is provided by the invention, when the silicon ingot is to move, the hardened polystyrene foam filled into the gaps can keep the silicon ingot not moving by a relative acting force with the side walls of the gaps so as to achieve an effect of fixing the silicon ingot. The silicon ingot is isolated from the crystal support by the isolating membrane, and thus, after squaring on the silicon ingot is completed, an operator can very easily take down the silicon ingot from the crystal support, so that the operation difficulty in the process of taking down the silicon ingot from the crystal support after squaring is greatly reduced and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, and more specifically, relates to a method for finding a square of a silicon ingot. Background technique [0002] With the development of science and the advancement of technology, countries all over the world pay more and more attention to energy saving, emission reduction and environmental protection. As an important part of energy conservation and emission reduction projects, the photovoltaic industry has developed rapidly. The complete industrial chain of the photovoltaic industry is: silicon material→ingot casting workshop→silicon wafer workshop→battery workshop→component workshop→application system→energy storage system. [0003] Silicon wafers are one of the essential raw materials for making solar cells. The production process is roughly as follows: grow the purified and processed silicon materials and cast them into silicon ingots, and then cut the silicon ingots into silicon bloc...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the silicon ingots are usually bonded directly to the crystal holder with foam glue. This method leads to difficulty in cutting the cut silicon block and the crystal holder due to the bonding effect of the foam glue after the prescribing is completed. Separation, in the process of removing the silicon block from the crystal tray, it takes a long time and manpower, and the operation of the staff is difficult, which affects the production efficiency
