Abstract
The invention belongs to the technical field of mechanical equipment, and relates to a precoated tin-coated copper belt, in particular to a critical component in a solar battery piece assembly. The precoated tin-coated copper belt comprises a copper substrate and an alloy layer, the surface of the copper substrate is coated by the alloy layer, and the periphery of the alloy layer is further coated by a scaling powder layer. Due to the fact that the periphery of the existing alloy layer is further coated by the scaling powder layer, in customer use, the finally obtained precoated tin-coated copper belt can be used without scaling powder, soaking and drying, auxiliary material cost can be saved for a customer, the production cycle is shortened, production efficiency is improved, and finally production cost of photovoltaic modules is reduced.
Description
Technical field
The invention belongs to mechanical equipment technical field, relate to a kind of precoating and be coated with the tin copper strips, specifically the critical component in the solar cell chip module.
Background technology
At present, along with The development in society and economy, people more and more pay attention to energy-saving and emission-reduction and reduce the cost of manufacturing, and are no exception in the photovoltaic field, and the cost of electricity-generating that reduces photovoltaic module is more and more important.
In the prior art, photovoltaic module need shift to an earlier date 30 minutes before use with tin-coated welding strip tin-coated welding strip is immersed in the scaling powder pond 15 minutes, took out airing again 5 minutes, and then 15 minutes ability of 60 degree oven dry is used, a large amount of uses of wait and scaling powder so for a long time, make client cost high not down, production cycle is long can't to shorten light, so photovoltaic producer all reduces production costs moving heaven and earth, the professional production manufacturer that we are coated with the tin copper strips as precoating also helps the client to solve this difficult problem moving heaven and earth.By constantly with Communication with Customer, exchange, discussion, and to client's workshop field assay, investigation back we find the client a large amount of auxiliary material scaling powders of waste and time wait in welding uses.Can bring the income of scaling powder 100% and efficient, the income in man-hour to the client if can address these problems.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of precoating simple in structure, ingenious, rational to be coated with the tin copper strips, this precoating is coated with the tin copper strips can save client's Material Cost and implementation efficiency lifting, reaches the purpose that reduces cost.
According to technical scheme provided by the invention: a kind of precoating is coated with the tin copper strips, comprises the copper material matrix and is coated in the alloy-layer of described copper material matrix surface, and be characterised in that: described alloy-layer periphery also is coated with the scaling powder layer.
As a further improvement on the present invention, the thickness of described scaling powder layer is 0.005-0.01mm.
The present invention compared with prior art, advantage is: the present invention is by being coated with tin copper strips periphery pre-coated soldering flux layer in existing precoating, making that the precoating finally obtain is coated with the tin copper strips can be without scaling powder when the client uses, need not soak, need not dry, for the client saves auxilliary material cost, shorten the production cycle, enhance productivity, and finally reduce the photovoltaic module production cost.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1, comprise copper material matrix 1, alloy-layer 2, scaling powder layer 3 etc.
As shown in Figure 1, the present invention is that a kind of precoating is coated with the tin copper strips, comprises copper material matrix 1 and is coated in the alloy-layer 2 on described copper material matrix 1 surface, and described alloy-layer 2 peripheries also are coated with scaling powder layer 3.
The thickness of described scaling powder layer 3 is 0.005-0.01mm.
The present invention increases by one the precoating operation when original welding is produced, be coated in the mode of special scaling powder by precoating on the welding in advance, concrete operations are to be coated with in the tin production engineering to increase coating apparatus, special scaling powder is added in the coating, precoating is coated with the tin copper strips and directly enters coating apparatus after being coated with tin, there is the twice coating to roll in the coating apparatus, precoating is coated with the tin copper strips and rolls interior process from coating, special scaling powder spray is coated with the tin copper strips through the coating wheel in precoating, the scaling powder whole precoating of parcel uniformly is coated with the tin copper strips under the effect of coating wheel, the precoating that coats is coated with the tin copper strips makes its surperficial scaling powder solidify to form uniform cured layer through low-temperature bake again, through air-cooled fulfiling assignment, namely finish processing again.The precoating of surface pre-coated soldering flux layer 3 is coated with the tin copper strips and becomes the film shape to invest precoating under 40 times of magnifying glasses to be coated with the tin copper strip surface, precoated shet be the boiling point of scaling powder layer 3 between 70 °-80 °, temperature adds thermal diffusivity greater than 85% more than 50 °.
The present invention is by being coated with tin copper strips periphery pre-coated soldering flux layer in existing precoating, making that the precoating finally obtain is coated with the tin copper strips can be without scaling powder when the client uses, need not soak, need not dry, for the client saves auxilliary material cost, shorten the production cycle, enhance productivity, and finally reduce the photovoltaic module production cost.
