Abstract
The utility model discloses a kind of silicon single crystal rod flaw-piece fixture be easy to and clamp, including upper holder, lower holder, rubber groove, rotating shaft, the upper holder and lower holder end are surface plate, and afterbody is lever；The rubber groove is arranged on holder end bottom surface, and its top is plane, and bottom is concave up arc surfaced；The upper holder and lower holder middle part are connected by axis of rotation.The utility model has the advantages that beneficial to band sawing machine shearing silicon single crystal rod flaw-piece, clamping stabilization and convenient clamping as silicon single crystal rod flaw-piece fixture.
Description
Technical field
The utility model is related to monocrystalline silicon manufacturing equipment field, more particularly to a kind of silicon single crystal rod flaw-piece for being easy to clamping is pressed from both sides
Tool.
Background technology
Traditional macromeritic polysilicon produces the difference of the production method of silicon single crystal rod because of casting technique and solar energy vertical pulling method,
There is a problem of that crystal grain is small, dislocation is more, battery efficiency is low, in order to solve polysilicon efficiency, produced it is a kind of between
Big crystal grain silicon chip (also referred to as quasi-monocrystalline silicon) between polysilicon and monocrystalline silicon, but the special seed crystal of such product needed, plus
Work cost is higher, low yield.After entering line evolution to silicon single crystal rod, flaw-piece can be left；And remained after utilizing silicon single crystal rod evolution
Under flaw-piece manufacture casting big crystal grain, the significant advantage with low cost.But the edge thickness and center thickness of monocrystalline flaw-piece
Very different, is unfavorable for that it plays seed crystal effect, it is therefore necessary to monocrystalline flaw-piece is processed, by the both sides of monocrystalline flaw-piece
Silicon material is removed, and makes the difference reduction of flaw-piece edge thickness and center thickness, thus obtains for casting macromeritic polysilicon
Edge skin material.If flaw-piece is individually directly placed on the processing platform of band sawing machine, and directly the silicon material on the both sides of flaw-piece cut
Prescind.
In the patent of Publication No. 202742557U：The fixture of remaining flaw-piece after a kind of new silicon single crystal rod evolution, its
It is characterized in：Including：Base, standing screw, rubber groove, top board, adjusting nut；Base is surface plate, and top board is surface plate, rubber
Groove is that upper end is the structure that plane and bottom are concave up arc, and rubber groove is provided with below base, and standing screw is upward
Linked together through the adjusting nut above the Kong Bingyu top boards on the hole on base, the hole on rubber groove, top board.It is utilized
Base and top constitute fixture by adjusting nut and standing screw, by rubber groove can with stable holding silicon single crystal rod flaw-piece,
And precision is higher.But because clamping is required for rotating adjusting nut and standing screw every time, so undoubtedly make operating efficiency big
It is big to reduce, and operation difficulty is increased, clamp very inconvenient.
Therefore it provides it is a kind of can either stable holding, high accuracy and convenient clamping silicon single crystal rod flaw-piece fixture, just turn into
Problem demanding prompt solution in the industry.
Utility model content
To solve the problems, such as that background technology is mentioned, the utility model proposes following technical scheme：
A kind of silicon single crystal rod flaw-piece fixture for being easy to clamp, including upper holder, lower holder, rubber groove, rotating shaft, it is described

It is described further：
A kind of silicon single crystal rod flaw-piece fixture for being easy to clamp, including upper holder 1, lower holder 2, rubber groove 3, rotating shaft 6,
The upper holder 1 and the lower end of holder 2 are surface plate, and afterbody is lever；The rubber groove 3 is arranged on clamping
The end bottom surface of part 1, its top is plane, and bottom is concave up arc surfaced；The upper holder 1 and the middle part of lower holder 2
Rotated by rotating shaft 6 and connected.
Preferably, the described end upper surface of lower holder 1 is provided with rubber blanket 5.
Preferably, described rubber blanket 5 is square bar long.
Preferably, the described upper surface of rubber blanket 5 is zigzag.
Preferably, the described bottom surface of rubber groove 3 is zigzag.
Preferably, described upper holder 1 and the lower trailing exterior surface of holder 2 are equipped with screw thread bar 7.
Some one exemplary embodiments of the present utility model only are described by way of explanation above, undoubtedly, for
One of ordinary skill in the art, in the case of without departing from spirit and scope of the present utility model, can be with a variety of
Mode is modified to described embodiment.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as
Limitation to the utility model claims.
