Abstract
The utility model relates to cutting steel wires in the field of photovoltaics or semiconductors, in particular to a special-shaped cutting steel wire. The cutting steel wire is in an elliptical cylinder or polygon structure. Compared with the prior art, the special-shaped cutting steel wire is novel and simple in structure. Due to the fact that the cutting steel wire is in the elliptical cylinder or polygon structure, rigidity and tensile strength of the steel wire are strengthened greatly, breakage rate of the steel wire is reduced effectively, cutting speed of the steel wire is increased, and cutting efficiency is improved. Particularly when used for cutting harder materials or materials difficult to be processed, the special-shaped cutting steel wire brings great convenience to cutting operation, and accordingly is worthy of being popularized, applied and industrialized.
Description
[technical field]
The utility model relates to the cutting steel wire in photovoltaic or the semiconductor applications, specifically a kind of abnormity cutting steel wire.
[background technology]
Solar photovoltaic technology is to be the technology of electric power with conversion of solar energy, and its core is the semiconductor substance that can discharge electronics, and the most frequently used semi-conducting material is a silicon.Quick growth along with the silicon materials cost, the thickness that reduces silicon chip becomes reduce cost the most direct and effective means, thin silicon chip means less silicon materials consumption, having played important function to reducing the solar-energy photo-voltaic cell cost, is that technological progress promotes one of important example that reduces cost.In order to realize reducing the purpose of silicon wafer thickness, extensively adopted the multi-thread cutting technique of silicon crystal at present in the world, it is different from cutting modes such as traditional knife saw sheet, grinding wheel, also be different from advanced laser cutting and interior circle cutting, its principle is silicon rod to be ground attached to the cutting blade material on the steel wire by the steel wire drive of a high-speed motion, thereby reaches cutting effect.
The multi-thread cutting technique of silicon crystal is compared with other cutting techniques, has efficient height, production capacity height, precision advantages of higher.The domestic multi-thread cutting technique of silicon crystal mostly is to adopt the cutting steel wire to carry mortar to grind silicon rod to realize the silicon chip cutting at present, its shortcoming is, tensile strength is low, wire broken rate is higher, thereby limited the cutting speed of cutting steel wire, cutting efficiency is also lower, particularly some are harder or more during difficult to machine material, then more not competent in cutting, have brought very big inconvenience for cutting work.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of modified cutting steel wire is provided, and has improved cutting efficiency greatly.
Design a kind of abnormity cutting steel wire for achieving the above object, it is characterized in that: described cutting steel wire is oval cylinder or gengon structure.
The cross section of described cutting steel wire is triangle, ellipse, rectangle or square.
The cross section average diameter of described cutting steel wire is 0.15-1mm.
The utility model is compared with prior art, novel structure, simple, because the cutting steel wire is oval cylinder or gengon structure, its hardness and tensile strength improve greatly, thereby effectively reduce wire broken rate, accelerated the cutting speed of steel wire, improve cutting efficiency, particularly when some harder or difficult material processed of cutting, brought very big convenience for cutting work, be worthy of popularization, and industrialization.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is structural representation of the present utility model (two);
Fig. 3 is structural representation of the present utility model (three);
Among the figure: 1, cutting steel wire.
[specific embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in drawings, the utility model is processed existing cutting steel wire through mould molding, make its cross section for oval, square, triangle, the cross section average diameter of cutting steel wire is 0.15mm, 0.20mm, 0.30mm, 0.40mm, 0.60mm, 0.80mm or 1mm, during cutting, this had the guiding of the cutting steel wire of oval cylinder or gengon structure by tens guide rollers, on the main line roller, form a bracing cable net, and silicon crystal to be processed is realized the feeding of workpiece by the decline of workbench, the mortar that the cutting Steel Wire Surface is carried is along with the high-speed motion of steel wire, directly obtain movement velocity and certain pressure, thereby directly silicon materials are carried out grinding and cutting.
The cross section of the utility model cutting steel wire can also be processed as rectangle or other shapes.
The utility model cutting steel wire purposes not only is used for the cutting of photovoltaic field silicon crystal, also can be used for the cutting of crystal, crystal glass, jewel etc.
The utility model is not subjected to the restriction of above-mentioned embodiment; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
