The invention discloses a diffuse reflection type tin-coated welding strip and a method for producing the same. The diffuse reflection type tin-coated welding strip comprises a copper strip and a tin coating on the copper strip, wherein the surface of the tin coating is provided with distributed pit-shaped bodies. The production method comprises the following steps of: raising the temperature in a tin furnace to between 230 and 250 DEG C, and putting the copper strip in metallic alloy coating solution in the tin furnace for immersion tin-coating, wherein the speed of the immersion tin-coating is controlled to be 1 to 2m/min; and taking the tin-coated welding strip subjected to the immersion coating out, and cooling the tin coating on the surface of the copper strip by an air blower and a screen arranged on the air blower to obtain the distributed pit-shaped bodies. Because the surface of the tin coating is provided with the distributed pit-shaped bodies, the physical indexes of the diffuse reflection type tin-coated welding strip are stable, and the diffuse reflection type tin-coated welding strip can diffuse sunlight, so that more sunlight can be reflected to a battery plate, and the received solar energy is increased.
Description
Technical field
The present invention relates to a kind of tin-coated welding strip that solar panel connects conduction that is used for, is a kind of diffuse reflection type tin-coated welding strip and production method thereof specifically.Have the diffuse reflection that sunlight is produced, help solar panel to accept more luminous energy.
Background technology
At present, the solar panel of selling on market tin-coated welding strip connected to one another has preferably that primary condition such as conductive capability and reasonable solderability is widely used.This tin-coated welding strip is with the 99%Sn1%Ag of copper strip surface immersion plating in the tin stove; 62%Sn/36%Pb2%Ag; 96.5%Sn3.55%Ag, 60%Sn/40%Pb; In arbitrary metal alloy plating solution of 63%Sn/37%Pb, the tin furnace temperature is controlled at about 250 ℃, speed regulation and control after come out of the stove, make its tin-coated welding strip of coming out of the stove part cool off by induced draft fan at 2m-3m/min, promptly obtain the tin-coated welding strip of smooth surface coating.But the coating smoother on the tin-coated welding strip surface that produces by said method, therefore in actual applications, owing to utilized a large amount of tin-coated welding strips to connect solar panel, when accepting illumination, make that having lubricious tin-coated welding strip surface can produce direct projection, more sunlight is reflected away, reduced the probability that solar panel is accepted sunlight in a large number.
Summary of the invention
In view of above-mentioned present situation, the invention provides a kind of diffuse reflection type tin-coated welding strip, produce diffuse reflection by tin-coated welding strip, can improve the energy that solar panel is accepted sunlight greatly, the conversion of more luminous energy is provided.
Another object of the present invention has provided the production method of diffuse reflection type tin-coated welding strip.
Technical solution of the present invention is achieved in that a kind of diffuse reflection type tin-coated welding strip, and what comprise that copper strips and surface thereof have is coated with the tin layer; Wherein, be coated with the hole shape body that the tin laminar surface has distribution described.Therefore, the hole shape that can utilize copper strip surface to distribute is coated with the tin layer, can produce diffuse reflection to sunlight, causes sunlight more to reflex on the solar panel, accepts more sunlight.
In above-mentioned, the described distribution that is coated with the hole shape body on the tin laminar surface is evenly to distribute or non-uniform Distribution.
Further, the hole shape body that is coated with on the tin laminar surface is to cheat shape body or hole heterogeneous shape body uniformly.
The hole shape body of indication is a concave body in above-mentioned.
The production method of diffuse reflection type tin-coated welding strip is:
1, at first the tin furnace temperature is warming up to 230-250 ℃, draws copper strips and enter and carry out immersion plating in the metal alloy plating solution in the tin stove and be coated with tin;
2, the speed control of copper strips immersion plating is at 1-3m/min;
3, immersion plating the is finished tin-coated welding strip of part of coming out of the stove, the tin layer cooling that be coated with that acts on copper strip surface through hair-dryer and the sieve nest air-supply of go up installing thereof forms the hole shape body that distributes.
According to the solution of the present invention, uniform sieve aperture on the related sieve nest, this sieve nest is positioned at the air outlet position of hair-dryer.
The cooling device of indication is the hair drier selected for use or other Fan Equipment in above-mentioned.
The metal alloy plating solution composition of indication of the present invention is: 99%Sn1%Ag; 62%Sn/36%Pb2%Ag; 96.5%Sn3.55%Ag, 60%Sn/40%Pb; Arbitrary metal alloy plating solution of 63%Sn/37%Pb.
In sum, diffuse reflection type tin-coated welding strip provided by the invention, has hole shape coating because of being coated with the tin copper strip surface, utilize the coating of these hole shapes to guarantee that not only the product physical index is stable, but also can produce diffuse reflection to sunlight, cause more sunlight to reflex on the cell panel, improved the energy of accepting sunlight and the power consumption of solar panel.Realizing the hole shape coating that the tin-coated welding strip surface has, mainly is to realize by the production method that reduces tin stove immersion plating temperature, immersion plating speed, sieve nest.
Description of drawings
Fig. 1 is the tin-coated welding strip schematic diagram;
Fig. 2 sieve nest schematic diagram of the present invention.
Embodiment
Below will the invention will be further described by specific embodiment.
See the described diffuse reflection type tin-coated welding strip of Fig. 1, comprise copper strips 1.Have on described copper strips 1 surface by what the immersion plating method formed and be coated with tin layer 2.Being coated with that this copper strips 1 has is distributed with hole shape body 3 on tin layer 2 surface.Therefore, utilization is coated with the tin layer 2 surperficial hole shape body 3 of going up can produce diffuse reflection to sunlight, in order to improve the more light energies of solar panel acceptance to being connected.In the present embodiment, the related distribution that is coated with tin layer 2 lip-deep hole shape body 3 is to adopt equally distributed mode.Equally, being coated with tin layer 2 lip-deep hole shape body 3 is to cheat the shape body uniformly.
Among the present invention, the distribution that is coated with tin layer 2 lip-deep hole shape body 3 can also be non-homogeneous distribution except that adopting even distribution mode.In like manner, described hole shape body 3 can be a hole heterogeneous shape body except that the shape body mode of equally distributed hole.
The production method that realizes foregoing invention may further comprise the steps:
1, at first copper strips is annealed, cleaning surfaces is handled, prefluxing, introduce the tin stove, temperature is controlled at 235 ℃, make copper strips be coated with tin by carrying out immersion plating in the metal alloy plating solution in the tin stove, by control tin furnace temperature, avoid the flowability of coating, help combining of copper strips and coating, for subsequent technique provides condition.
