Description
Technical field
A kind of silicon cored wire trace plain grinding trimming device is the utility model is related to, belongs to technical field of polysilicon production.
Background technology
At present, it is all the conventional hydrogen reduction of trichlorosilane that the technique of domestic production polysilicon is most of at present, i.e. improvement west
The capital equipment of Men Zifa, improved Siemens or other similar approach production major diameter polysilicon is polycrystalline silicon reducing furnace, more
Crystal silicon reduction furnace is electrified on elongated silicon core, is made the heating of silicon core rubescent, until surface temperature reaches 1100 degrees Celsius, is led to
Enter high-purity trichlorosilane and hydrogen, make it that hydrogen reduction reaction occur at high temperature, the silicon packing of molecules in trichlorosilane is existed
On silicon core, its diameter is set constantly to increase, in general, it can also be square that the diameter of silicon core, which at 7-10 millimeters, can be circle,
Or other shapes, diameter is constantly increased to 120-200 millimeters eventually through hydrogen reduction reaction, produce high-purity solar energy
The polysilicon device of level 6N or electron level 11N can not be suitable for the test of square silicon core in factory.
The preparation method of silicon core has two kinds at present, and traditional method is to use CZ methods（Melt czochralski method in area）, i.e., diameter in 20-
50 millimeters of silicon rod uses high-frequency induction heating in the vacuum hearth full of inert gas, makes its top local melting, from top
Seed crystal of 1 diameter at 5-10 millimeters is put into, then slowly lifting upwards, becomes diameter at 7-10 millimeters, length exists
Elongated silicon core between 1900-3000 millimeters, the drawback is that pull rate is slow, is generally 8-12 mm/mins, draws 12 meters
Silicon core need 4 it is small when, low production efficiency, power consumption is big, and equipment investment is big.
Another kind is to use diamond tool patterning method, and Diamond Wire Technology companies of the U.S. develop use
The elongated silicon multiline cutting machine of numerical-control polysilicon of diamond wire, the preparation for silicon core.By using the upper diamond of plating
The finer wire line of particulate is moved back and forth at high speed on workpiece to be machined or unidirectional movement, and silicon rod is pressed in the lathe diamond
Line intersects on the square gauze of composition, so that the silicon rod to be cut into elongated silicon core.Its advantage is fairly obvious, when 10-12 is small
200 or so 2 meters long 7X7 or 8X8 millimeters of square silicon core can be cut out, power consumption is small, high in machining efficiency.
At present by silicon core made from diamond tool patterning method, due to that can not ensure silicon rod and steel wire in cutting process
Line is completely vertical, and in cutting process between wire and silicon rod unavoidably there are certain vibrations and dislocation, therefore cut
There is cutting stria in the silicon wicking surface cut, the quality of product can be had an impact, serious situation results even in product
Scrap.

State adjusting bolt lower end with flexible member upper end to be connected, the flexible member lower end is connected with pressure roller.
Waist-shaped hole is vertically offered on the roller seat, the pressure roller both ends are plugged in waist-shaped hole.
Two outer end position of pressure roller is provided with block.
Adjusting screw rod is vertically provided with the fixed seat, the adjusting screw rod lower end is connected with slide, institute
State adjusting screw rod upper end and be provided with regulation handle.
The adjusting screw rod side is provided with fixed plate, and caging bolt, institute are vertically provided with the fixed plate
Caging bolt lower end is stated to offset with slide top.
Baffle is provided with front side of the workbench, the baffle is provided with discharge port in the position of plain grinding track.
Compared with prior art, the utility model has the advantage of：
A kind of silicon cored wire trace plain grinding trimming device of the utility model, its is simple in structure, easy to operate, can be to silicon wicking surface
Because the stria that cutting produces effectively is repaired, work efficiency is high, while final product quality has been effectively ensured.
