Problems solved by technology

[0003] When the above technology is realized, one horizontal silicon core and two vertical silicon cores are connected through bridging technology. The Chinese patent previously applied by the inventor discloses a porous silicon core that can effectively increase the contact area and reduce the resistance. Core overlapping method, this patent proposes a method of overlapping spherical silicon cores, which is to arrange silicon core spheres at both ends of the horizontal silicon core, and respectively set jacks at the lower parts of the two silicon core spheres , the socket on the upper end of the vertical silicon core is matched with the socket to form a connection method that increases the contact area and reduces the resistance; however, in practical applications, it is found that when drilling holes on the horizontal silicon core sphere, the horizontal silicon core often results in Cracks or even fractures occur on the sphere, and the yield is relatively

Abstract

The invention provides a double-headed bridge type crystalline material grinding machine and relates to crystalline material machining equipment. The double-headed bridge type crystalline material grinding machine is characterized in that the middle of a crystal bar (18) is clamped by a crystal bar clamping mechanism, two grinding wheels (14) of a grinding mechanism at one end of the crystal bar respectively correspond to two sides of one end of the crystal bar, the crystal bar is ground at intervals respectively by the two grinding wheels on a base (21), and the rear parts of the two grinding wheels are respectively and externally connected with a power mechanism or a motor (24); and two grinding wheels of the grinding mechanism at the other end of the crystal bar respectively correspond to two sides of the other end of the crystal bar, the crystal bar is ground at intervals respectively by the two grinding wheels on the base, and the rear parts of the two grinding wheels are respectively and externally connected with a power mechanism or a motor. The use of the double-headed bridge type crystalline material grinding machine realizes the purpose of stably grinding the crystal bar, effectively improves the mechanical degree for machining the crystal bar, and overcomes the defect of necessity to pull a silicon core ball in the prior art.

Description

【Technical field】 [0001] The invention relates to a crystal material processing equipment, in particular to a bridge-type crystal material double-head grinder. 【Background technique】 [0002] In the process of polysilicon production using the Siemens method, silicon core lapping technology is a very important link, which is mainly used in the reduction reaction process of polysilicon production. The principle of the reduction reaction process in this link is: the reduction reaction is carried out in a closed reduction furnace, and several closed loops are formed by overlapping silicon cores in the reduction furnace before loading the furnace, that is, in the jargon "Bridge"; each closed circuit is composed of two vertical silicon cores and one horizontal silicon core; the two vertical silicon cores of each closed circuit are respectively connected to two electrodes on the bottom of the furnace, and the two electrodes are respectively connected The positive and negative pole...
