Abstract
The invention provides a method for cutting a polycrystalline large ingot, and relates to the technology for cutting the polycrystalline large ingot. In the invention, a soft glass is bonded on a workpiece plate; and then the polycrystalline large ingot is positioned on the soft glass and is cut. In the invention, the soft glass is arranged between the polycrystalline large ingot and the workpiece plate so as to form insulation, so that the electric conductivity between the polycrystalline large ingot and the workpiece plate can be effectively isolated; a false grounding alarm phenomenon is avoided; production risks can be reduced; and the safety of production equipment can be effectively protected.
Description
Technical field
The present invention relates to the cutting technique of the big ingot of polycrystalline.
Background technology
For the polycrystalline that is shaped is divided into the rectangle polycrystalline silicon rod that some sections are square, production technology directly being bonded on the work plate, placing on the cutting machine then and directly cuts apart mostly between the cutting car of the big ingot of polycrystalline.This cutting process will run into cutting machine " grounding alarm " prompting, and all belongs to wrong report mostly.As for fear of false alarm takes place; Before the big ingot cutting of polycrystalline, cutting machine has been carried out " grounding alarm " shielding; But owing to taking this measure but not report to the police when machine needs " grounding alarm " because of real fault afterwards; Therefore also cut the big ingot of the polycrystalline that given up, even the damage that also can cause equipment that has.It more than is the long-term problem that never solves of colleague.
Summary of the invention
The object of the invention is to propose a kind of cutting method that the big ingot of polycrystalline of mechanical false alarm can not take place in the big ingot cutting process of polycrystalline.
The technological means that proposes in order to overcome the above problems, the present invention is first at bonding block of soft glass of work plate, and then the big ingot of polycrystalline is placed on the soft glass, cuts again.
The present invention is provided with soft glass between big ingot of polycrystalline and work plate; Formed insulation, the electric conductivity between interval big ingot of polycrystalline and the work plate is avoided the phenomenon of " grounding alarm " by mistake effectively; Not only reduced production risk, simultaneously also to having protected the security of production equipment effectively.
The thickness of soft glass according to the invention is 3～8mm.
The thickness of preferred soft glass is 5mm.
The specific embodiment
The production operation step:
1, at bonding block of thick rectangle soft glass of a 3～8mm of work plate, the thickness of preferred soft glass is 5mm.
2, the big ingot of polycrystalline is placed on the soft glass.
3, open the big ingot of polysilicon cutting machine,, the big ingot of each piece is cut into four rectangle polycrystalline silicon rods by technological requirement.
Claims (3)
1. the cutting method of the big ingot of polycrystalline is characterized in that elder generation at bonding block of soft glass of work plate, and then the big ingot of polycrystalline is placed on the soft glass, cuts again.
2. according to the cutting method of the big ingot of the said polycrystalline of claim 1, the thickness that it is characterized in that said soft glass is 3～8mm.
3. according to the cutting method of the big ingot of the said polycrystalline of claim 1, the thickness that it is characterized in that said soft glass is 5mm.
