Abstract
The utility model relates to sawing wires in the photovoltaic field or the semiconductor field, in particular to a multi-strand sawing wire which comprises more than two strands of sawing wires. Each strand of sawing wires are spirally wound to each other into a whole, to form a rope-shaped structure. Compared with the prior art, the multi-strand sawing wire has the advantages that the structure is novel and simple, after the multi-strand sawing wire is adopted, the service life of a wire is effectively prolonged, the cost for silicon chip cutting is greatly reduced, and the cost of photovoltaic power generation is reduced. In addition, gaps among the strands of sawing wires can carry more mortar, so that the cutting efficiency is effectively improved, and the cutting speed is quickened. Therefore, the multi-strand sawing wire is worthy of popularization and application.
Description
[technical field]
The utility model relates to the cutting steel wire in photovoltaic or the semiconductor applications, specifically a kind of multiply 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.But in the multi-thread cutting technique of silicon crystal, used cutting steel wire can not be recycled, and is expendable consumed product.Be accompanied by the fast development of photovoltaic industry and the active demand of silicon chip cutting, silicon crystal cuts required cutting steel wire and the situation that supply falls short of demand occurs, and the manufacturing technique requirent of cutting steel wire is high, only there is the Very few companies can production and selling at present in the world, becomes current very important problem so how to reduce the wire broken rate of cutting steel wire.
[summary of the invention]
The purpose of this utility model is exactly will solve above-mentioned deficiency and a kind of multiply cutting steel wire is provided, and has improved cutting efficiency greatly, has effectively reduced wire broken rate, has reduced cost.
Design a kind of multiply cutting steel wire for achieving the above object, form, it is characterized in that: be spirally wound on mutually together between the described per share cutting steel wire, form rope-like constructed by the cutting steel wire more than at least two strands.
The cross section of described per share cutting steel wire is circular, and described sub-thread cutting steel wire cross-sectional diameter is 0.08-0.3mm.
The utility model is compared with prior art, novel structure, simple, adopted multiply cutting steel wire after, effectively prolonged service life of steel wire, greatly reduced the cost of silicon chip cutting, reduced the cost of photovoltaic generation.And more mortar can be carried in the mutual gap of multiply cutting steel wire, thereby has effectively improved cutting efficiency, and has accelerated cutting speed, so the utility model is worthy of popularization.
[description of drawings]
Fig. 1 is the cross-sectional view of three bursts of cuttings of the utility model steel wire;
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 spirally wound on the existing cutting steel wire of three strands (can also be two strands or multiply) together mutually, the cross section of wherein per share cutting steel wire is circular, cross-sectional diameter is 0.08mm, 0.10mm, 0.12mm, 0.20mm or 0.3mm, makes its multiply that forms rope-like constructed cutting steel wire.During cutting,, on the main line roller, form a bracing cable net, and silicon crystal to be processed carries out grinding and cutting by the feeding of the decline realization workpiece of workbench to silicon materials with of the guiding of this multiply cutting steel wire by tens guide rollers.Owing to have the gap between multiply cutting steel wire, thereby can carry more mortar, accelerated cutting speed, improved cutting efficiency.
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.
Claims (2)
