Description
Technical field:
The present invention relates to field polysilicon, relate in particular to a kind of polycrystal silicon ingot cutting with the brilliant holder in location.
Background technology:
Containing the human inexhaustible energy in the sun.The sun is ceaselessly sending huge energy in the cosmic space.According to calculating, the energy that only sends a second just is equivalent to 1.3 hundred million hundred million tons of standard coal burning time institute's liberated heats.And arrive the solar energy of earth surface, be about as much as 200,000 times of all generating capacity summations of the present whole world.The solar energy that earth every day receives is equivalent to 200 times of gross energy that the whole world consumed in 1 year.Compare with other energy, that solar energy can not produce is poisonous, pernicious gas and waste residue, thereby free from environmental pollution.Sunshine can obtain everywhere simultaneously, and is easy to use, safe; With low cost, can regenerate.
Now, the global solar battery production increases fast, direct pull the rapid growth of polysilicon demand.Being in great demand of whole world polysilicon, in the prior art, in the cutting action to polysilicon; Usually adopt a kind of tray loading polycrystal silicon ingot, Chinese patent CN202053393U discloses a kind of polycrystal silicon ingot cutting with brilliant holder, and it comprises base plate and polycrystal silicon ingot; Polycrystal silicon ingot is arranged at the base plate middle part, and is bonding through gap filler between base plate and the polycrystal silicon ingot, is provided with some locking devices around the base plate; Locking device comprises first screw and second screw, and first screw is fixed on the base plate, and second screw runs through first screw; Between second screw and first screw for being threaded, second tip of screw and polycrystal silicon ingot outer wall near.Though this device can be fixed polycrystal silicon ingot, following deficiency appears in locking device in actual use:
1. only depend on first screw to be fixed on the base plate; And second screw is bigger to the location thrust of polycrystal silicon ingot, makes the double-screw bolt of the screw of winning and the force localization between the screwed hole on the base plate, is easy to cause the screwed hole wearing and tearing on the base plate or damage; Also can cause first screw to fracture when serious
2. be provided with the screwed hole of second screw that is used to spin at the top of first screw, its center must with the axis conllinear of first screw, and be difficult in fact accomplish that when second screw of screwing was exerted pressure, first screw will rotate like this, produce falseness and compress.
Hence one can see that, and existing polycrystal silicon ingot cutting is unreasonable with the locking device design of brilliant holder, and it is unreliable that the location clamps, and service life is not long.When locking device damages, can also change,, then be difficult to repair if the retaining thread hole on the base plate is damaged.Therefore must improve the locking device of polycrystal silicon ingot cutting with brilliant holder.
Summary of the invention:
The object of the invention is to provide a kind of polycrystal silicon ingot cutting with the brilliant holder in location, and it is simple in structure, and is easy for installation, reliable clamping, long service life.
The technical scheme that the present invention takes is following:
A kind of polycrystal silicon ingot cutting comprises base plate, side locking device, angle locking device and polycrystal silicon ingot with the brilliant holder in location, is provided with vertical cutting groove, transverse cuts groove in the upper surface of base plate; Around base plate, form the equidistant side locating module that distributes, form the angle locating module at four jiaos of places, the some grids by vertical cutting groove and transverse cuts groove are divided into is characterized in that: the bottom at base plate is provided with supporting seat; In grid, be provided with bonding hole, on the locating module of side, be provided with two fixedly counterbores, the center of locating module is provided with a fixedly counterbore at the angle; The side locking device is arranged on the locating module of side; The angle locking device is arranged on the locating module of angle, and said side locking device comprises locating rack and lock-screw, and locating rack is down " U " type; Constitute by two location steel nails and location-plate; Location-plate is connected the top of two location steel nails, and its bottom straight cutting is gone among the fixedly counterbore on the locating module of side, and lock-screw runs through locating rack; Lock-screw is terminal to fit tightly with the polycrystal silicon ingot outer wall; Said angle locking device comprises location steel nail, centring ring and lock-screw, and steel nail bottom, location straight cutting is gone among the fixedly counterbore on the locating module of angle, and centring ring is positioned at the top of location steel nail; Lock-screw forms with the location steel nail through centring ring and is threaded, the terminal outer wall with polycrystal silicon ingot of lock-screw near.
Further, the grid that in base plate, is formed centrally is 25, and the side locating module that around base plate, forms has 5.
Further, the lock-screw of side locking device is fixed on the central authorities of the location-plate on the locating rack, forms with location-plate to be threaded.
Further, in the locking device of side, lock-screw and locating rack connection are provided with packing ring, or in the locking device of angle, lock-screw is provided with packing ring with steel nail connection, location.
Further, in the locking device of side, the contacted end face of lock-screw and polycrystal silicon ingot is provided with a nut, or in the locking device of angle, the contacted end face of lock-screw and polycrystal silicon ingot is provided with a nut.
Owing to the invention solves described defective among the background technology, the side locking device that around base plate, is provided with is made up of locating rack and lock-screw that two location steel nails and location-plate are formed by connecting, and the locating rack of this structure can play more powerful bracing force to polycrystal silicon ingot; And having disperseed the pressure of polycrystal silicon ingot to the side locking device, it adopts direct insertion connected mode, makes that the installation steps of this side locking device and base plate and demounting procedure are all easy to operate; Can not waste on the too many time, and in long-term use, can not cause wearing and tearing to base plate easily; Increased the service life of base plate greatly; Lock-screw is arranged at the central part of location-plate, makes the end of lock-screw and the outer face of polycrystal silicon ingot combine closely the situation that can not cause falseness to compress; Angle locking device in that four jiaos of places of base plate are provided with is made up of location steel nail, centring ring and lock-screw; Steel nail bottom, location straight cutting is gone among the fixedly counterbore on the locating module of angle, and centring ring is positioned at the top of location steel nail, and lock-screw forms with the location steel nail through centring ring and is threaded; Because the area that polycrystal silicon ingot is four jiaos is minimum; So this angle locking device can make lock-screw that the most firm effect is played at four angles of polycrystal silicon ingot, accurate positioning can not have influence on the processing of line cutting yet.
