The utility model discloses with the even full cover solder design of tradition, change into the segmentation and cover the solder design, match solder overlay area and battery piece figure simultaneously, the welding effect of area to the battery piece has been guaranteed to weld, adopt low ventilative polymer butt welding area non-solder to cover the region and protect, reduce the acid gas to the corruption of welding area substrate, guarantee to weld the reliability of area in the use, low ventilative polymer can not lead to the fact the influence to the light-reflecting structure of preparation in welding process, better light reflection reutilization effect has been guaranteed.
Description
Technical Field
The utility model belongs to the technical field of the high performance is resistant to wait to weld and takes, concretely relates to coating unit who welds the area.
Background
The photovoltaic module is used for converting solar energy into electric energy, the photovoltaic module comprises a plurality of photovoltaic cell pieces, two adjacent photovoltaic cell pieces are connected in series through a welding strip, and the welding strip is connected with the main grid of the cell and used for collecting and transmitting current.
In order to realize the conductive connection with the battery piece, the outer surface of the welding strip substrate is always coated with a layer of welding flux, but in the prior art, as shown in fig. 2, the welding strip of the assembly is uniformly coated with a layer of welding flux on the surface to form a welding strip with a consistent appearance. When the surface reflecting structure is manufactured, the reflecting effect of the welding strip is easily influenced by the welding flux, and the welding flux can be heated and melted in the welding process to flow, so that the original reflecting pattern is changed, the reflecting effect cannot be expected, the light guide function cannot be fully exerted, and the better incident light absorption and utilization effect cannot be achieved. In addition, full-coating solder also greatly increases the material cost of the solder strip without significant gain in the performance of the assembly.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the not enough of above prior art, provide a high performance of segmentation coating solder is able to bear or endure time to weld and takes, weld and take and divide into coating region and non-coating region, coating region be the solder segmentation coating in the region on welding the area surface, non-coating region for welding take the exposed portion, non-coating region uses low gas permeability polymer to cover.
Furthermore, the polymer with low air permeability is a hot melt layer, and the material of the hot melt layer is one of ethylene-butylene copolymer, ethylene-octene copolymer, isobutylene homopolymer, isobutylene-isoprene copolymer, brominated or chlorinated butyl rubber, and brominated isobutylene-p-methylstyrene copolymer.
Further, the thickness of the hot melt layer is 1 to 50 mm.
Furthermore, the cross section of the welding strip is polygonal.
Further, the solder strip is circular in cross section.
Has the advantages that:
with traditional even full cover solder design, change into segmentation cover solder design, match solder overlay area and battery piece figure simultaneously, guaranteed the welding effect of solder strip to the battery piece, adopt low ventilative polymer to protect the solder strip non-solder overlay area, reduce the corruption of acid gas to the solder strip substrate, guarantee the reliability of solder strip in the use, low ventilative polymer can not lead to the fact the influence to the reflective structure of preparation at the welding in-process, better light reflection reutilization effect has been guaranteed.

Detailed Description
In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
The implementation example is as follows:
a high-performance weather-resistant solder strip coated with solder in sections is characterized in that a solder strip 1 is divided into a coating area 2 and a non-coating area 3, the coating area 2 is an area formed by coating the solder on the surface of the solder strip in sections, the non-coating area 3 is an exposed part of the solder strip 1, and the non-coating area 3 is covered by a low-permeability polymer.
As shown in fig. 1;
the welding flux is coated in sections matched with the specific requirements of the cell, so that the use amount of the high-cost welding flux can be effectively reduced, and the welding effect of the welding strip cannot be influenced by the design because the welding flux only generates the welding action at the position contacted with the main grid area of the cell. Meanwhile, the non-coating area 3 is covered and protected by the low-permeability polymer, so that the direct exposure of the base material and the corrosion caused by the base material are avoided. Meanwhile, the non-coating area 3 can be designed into a light reflecting structure, and the traditional solder full-coverage design can greatly influence the manufactured light reflecting structure because the solder can be heated, melted and flowed in the welding process. This patent covers through adopting the polymer, can not lead to the fact the influence to the reflection of light structure of preparation in welding process, has guaranteed better light reflection reutilization effect.
The photovoltaic module based on this patent technique can be with the leaded light function full play of solder strip, has better incident light absorption and utilizes the effect, can promote output, and the segmentation coating solder can effectively practice thrift the cost simultaneously, does benefit to photovoltaic power generation's flat price and goes on the net.
The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
