Abstract
The utility model discloses a wafer holder for cutting a polycrystalline silicon ingot, comprising a soleplate and a polycrystalline silicon ingot, wherein the polycrystalline silicon ingot is arranged in the middle of the soleplate, which is adhered to the polycrystalline silicon ingot through a joint mixture; a plurality of locking devices are arranged at the four sides of the soleplate; the locking devices comprise first bolts and second bolts; the first bolts are fixed to the soleplate while the second bolts penetrate through the first bolts; the second bolts are in threaded connection with the first bolts; and the tail ends of the second bolts are tightly closed to the outer wall of the polycrystalline silicon ingot. The wafer holder can fix the polycrystalline silicon ingot effectively through the locking devices and prevent errors when performing wire cutting on the polycrystalline silicon ingot; and the wafer holder is simple in installation, good in locking effect, accurate in location and low in cost.
Description
Technical field
The utility model relates to field polysilicon, relates in particular to a kind of polycrystal silicon ingot cutting and holds in the palm with brilliant.
Background technology
Along with the develop rapidly of information technology and solar energy industry, the whole world is swift and violent to the demand growth of polysilicon, and supply falls short of demand in market.The output of world's polysilicon 2005 was 28750 tons, and wherein semiconductor grade is 20250 tons, and solar level is 8500 tons.The semiconductor grade demand is about 19000 tons, and is slightly superfluous; The demand of solar level is 15600 tons, and supply falls short of demand.In recent years, the global solar battery production increases fast, direct pull the rapid growth of polysilicon demand.Whole world polysilicon turns to by drug on the market that supply falls short of demand.Influenced by this, go up fast as the polysilicon price of solar cell primary raw material.
In the prior art, the general tray loading polycrystal silicon ingot that adopts during the polycrystal silicon ingot cutting, then to its cutting, yet the pallet fixed effect is bad, and precision can not get guaranteeing.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of polycrystal silicon ingot cutting that simple, accurate positioning, convenient cutting be installed with brilliant holder.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of polycrystal silicon ingot cutting is held in the palm with brilliant, comprise base plate, polycrystal silicon ingot, described polycrystal silicon ingot is arranged on the base plate middle part, bonding between base plate and the polycrystal silicon ingot by gap filler, be provided with some locking devices around the base plate, described locking device comprises first screw and second screw, described first screw is fixed on the base plate, described second screw runs through first screw, between second screw and first screw for being threaded, described second tip of screw and polycrystal silicon ingot outer wall near.
According to another embodiment of the present utility model, a kind of polycrystal silicon ingot cutting further comprises described polycrystal silicon ingot four limits with brilliant holder, and each evenly is provided with five locking devices, and polycrystal silicon ingot respectively is provided with a locking device for four jiaos.
According to another embodiment of the present utility model, a kind of polycrystal silicon ingot cutting comprises further that with brilliant holder described base plate is a square.
According to another embodiment of the present utility model, a kind of polycrystal silicon ingot cutting further comprises the diameter of the diameter of described first screw greater than second screw with brilliant holder.
According to another embodiment of the present utility model, a kind of polycrystal silicon ingot cutting comprises further that with brilliant holder described gap filler is the polyurethane foam gap filler.
The utility model has solved the defective that exists in the background technology, by locking device, can effectively polycrystal silicon ingot be fixed, and prevents from polycrystal silicon ingot is carried out producing error when line cuts, and simple, good, the accurate positioning of locking effect are installed, and cost is lower.
