Description
Technical field
The utility model relates to a kind of silicon core cutting machine crystal cup, belongs to technical field of polysilicon production.
Background technology
At present, the technique major part of current domestic production polysilicon is all the conventional hydrogen reduction of trichlorosilane, i.e. improved Siemens, the capital equipment of improved Siemens or other similar approach production major diameter polysilicons is polycrystalline silicon reducing furnaces, polycrystalline silicon reducing furnace is electrified on elongated silicon core, silicon core is heated rubescent, until surface temperature reaches 1100 degrees Celsius, pass into high-purity trichlorosilane and hydrogen, it is made at high temperature hydrogen reduction reaction to occur, make silicon packing of molecules in trichlorosilane on silicon core, its diameter is constantly increased, usually, the diameter of silicon core is at 7-10 millimeter, can be circle also can be square, or other shapes, diameter is made constantly to increase to 120-200 millimeter eventually through hydrogen reduction reaction, produce the polysilicon of high-purity solar level 6N or electron level 11N.
The preparation method of existing silicon core has two kinds, traditional method is with CZ method (czochralski method is melted in district), namely diameter is used high-frequency induction heating at the silicon rod of 20-50 millimeter in the vacuum hearth being full of inert gas, make its top local melting, the seed crystal of 1 diameter at 5-10 millimeter is put into from top, then slowly upwards lift, become diameter at 7-10 millimeter, the elongated silicon core of length between 1900-3000 millimeter, its shortcoming is that pull rate is slow, be generally 8-12 mm/min, the silicon core drawing 12 meters needs 4 hours, production efficiency is low, power consumption is large, equipment investment is large.
Another kind uses diamond tool patterning method, and Diamond Wire Technology company of the U.S. develops the elongated silicon multiline cutting machine of numerical-control polysilicon adopting diamond wire, for the preparation of silicon core.By utilizing the finer wire line of the upper diamond particle of plating to move back and forth at high speed or single-way moving on workpiece to be machined, silicon rod being pressed in this lathe diamond wire and intersecting on the square gauze of composition, thus this silicon rod is cut into elongated silicon core.Its advantage is fairly obvious, and within 10-12 hour, can cut out the square silicon core of 7X7 or the 8X8 millimeter of about 200 2 meters long, power consumption is little, and working (machining) efficiency is high.
During the cutting of silicon core need silicon rod to be suspended from cutting machine, due to silicon rod heavier-weight, the process that therefore hangs is very inconvenient, greatly constrains the raising of production efficiency.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of silicon core cutting machine crystal cup, it greatly facilitates the suspension process of silicon rod, improves the production efficiency of silicon core cutting.
The purpose of this utility model is achieved in that a kind of silicon core cutting machine crystal cup, it comprises the first linkage section, the second linkage section and the 3rd linkage section that connect successively, described first linkage section top is provided with lifting round platform, described first linkage section and the second linkage section junction and the second linkage section and the 3rd linkage section junction are provided with spacing round platform, are provided with sticky stick cylinder bottom described 3rd linkage section.
Compared with prior art, the utility model has following beneficial effect:
A kind of silicon core of the utility model cutting machine crystal cup, it greatly facilitates the suspension process of silicon rod, improves the production efficiency of silicon core cutting.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of silicon core of the utility model cutting machine crystal cup.
Wherein:
First linkage section 1
Second linkage section 2
3rd linkage section 3
Lifting round platform 4
Spacing round platform 5
Sticky stick cylinder 6
Silicon rod 7.
Detailed description of the invention
See Fig. 1, a kind of silicon core of the utility model cutting machine crystal cup, it comprises the first linkage section 1, second linkage section 2 and the 3rd linkage section 3 that connect successively, described first linkage section 1 top is provided with lifting round platform 4, described first linkage section 1 and the second linkage section 2 junction and the second linkage section 2 and the 3rd linkage section 3 junction are provided with spacing round platform 5, are provided with sticky stick cylinder 6 bottom described 3rd linkage section 3.
