A kind of automatic welding equipment for single crystal furnace

Abstract

The invention discloses an automatic welding equipment for a single crystal furnace, and relates to the technical field of welding equipment. The device includes a base plate, a support column is rotatably installed at the top middle of the base plate, and a first motor is fixedly installed at the bottom end of the base plate. The invention can collect, purify and discharge the waste gas generated in the welding process, avoid the waste gas from being diffused and pollute the air, so that the welding process is more environmentally friendly, and the burrs on the top wall of the furnace body can be polished at the same time of welding, so as to avoid the influence of the burrs. Welding, at the same time, the back and forth movement of the grinding rod can be realized, which can prevent one place from always in contact with the top wall of the furnace body for grinding, thereby prolonging the service life of the grinding rod and reducing the replacement frequency of the grinding rod. It can realize the grinding rod after welding. To avoid the situation where the same grinding rod is used all the time, its temperature continues to rise and the grinding rod is damaged.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, in particular to an automatic welding equipment of a single crystal furnace. Background technique [0002] A single crystal furnace is a device that uses a graphite heater to melt polycrystalline materials such as polycrystalline silicon and grow dislocation-free single crystals by the Czochralski method in an inert gas (nitrogen, helium-based) environment. [0003] During the production of the single crystal furnace, the top of the furnace body and the top fittings need to be welded. When welding, welding equipment is required. The existing welding equipment cannot handle a large amount of waste gas generated by welding during use. It causes the waste gas to drift into the air to pollute the air, which is not conducive to environmental protection. In addition, when the existing welding equipment is in use, in order to avoid the burr on the welding surface from affecting the welding, th...

AI Technical Summary

Problems solved by technology

[0003] During the production of the single crystal furnace, it is necessary to weld between the top of the furnace body and the top accessories. When welding, welding equipment is required. The existing welding equipment cannot handle a large amount of waste gas generated by welding. As a result, exhaust gas floats into the air and pollutes the air, which is not conducive to environmental protection. In addition, when the existing welding equipment is in use, in order to avoid the burrs on the welding surface from affecting the welding, the burrs are usually polished by the grinding rods installed on the welding equipment. When grinding, the position of the grinding rod is fixed, so that the contact surface with the burr is fixed, resulting in one area of ​​the grinding rod always in contact with the burr, resulting in excessive wear and tear, requiring frequent replacement of the grinding rod, and continuous use of the same grinding rod for work will be difficult As a result, the temperature of the grinding rod continues to rise and damage the grinding rod
