A kind of solar cell welding method provided by the invention, comprising:
The baffle plate of the hollow-out parts corresponding with the position of to-be-welded region is provided with in the surface coverage of solar cell;
Above described baffle plate, carry out Infrared irradiation, utilize the infrared light through described hollow-out parts to weld described to-be-welded region.
Preferably, in above-mentioned solar cell welding method, infrared generator is utilized to carry out Infrared irradiation above described baffle plate.
Above-mentioned solar cell auxiliary welding equipment provided by the invention, owing to comprising the baffle plate of all surfaces at least covering solar cell, described baffle plate is provided with the hollow-out parts corresponding with the position of to-be-welded region, therefore when infrared welding, baffle plate can be formed for the region beyond to-be-welded region and stop, thus to avoid in infrared welding process the battery short time and the decay that causes of the Infrared irradiation of high strength, thus there will not be the reduction of the power that dispatches from the factory of assembly, above-mentioned solar cell welding method provided by the invention, the surface coverage being included in solar cell is provided with the baffle plate of the hollow-out parts corresponding with the position of to-be-welded region, Infrared irradiation is carried out above described baffle plate, the infrared light through described hollow-out parts is utilized to weld described to-be-welded region, region beyond to-be-welded region so just can be made not by Infrared irradiation, avoid battery to produce decay, the power that dispatches from the factory of Assurance component.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The schematic diagram of a kind of solar cell auxiliary welding equipment that Fig. 1 provides for the embodiment of the present application;
The flow chart of a kind of solar cell welding method that Fig. 2 provides for the embodiment of the present application.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of solar cell auxiliary welding equipment that the embodiment of the present application provides as shown in Figure 1, the schematic diagram of a kind of solar cell auxiliary welding equipment that Fig. 1 provides for the embodiment of the present application.This device comprises the baffle plate 1 of all surfaces at least covering solar cell, and described baffle plate 1 is provided with the hollow-out parts corresponding with the position of to-be-welded region.
Above-mentioned solar cell auxiliary welding equipment, owing to comprising the baffle plate 1 of all surfaces at least covering solar cell, described baffle plate 1 is provided with the hollow-out parts 2 corresponding with the position of to-be-welded region, therefore when infrared welding, baffle plate 1 can be formed for non-to-be-welded region and stop, thus avoid to the decay that battery causes in infrared welding process, thus the power that dispatches from the factory of Assurance component.
Preferably, in above-mentioned solar cell auxiliary welding equipment, described hollow-out parts 2 is the rectangle hollow-out parts corresponding with the position of the main grid of described solar cell.Due in the production process of solar cell, general is all weld the position of main grid, therefore hollow-out parts 2 is set to corresponding with the position of main grid, just can make in welding process, infrared light is only irradiated to the position of main grid by hollow-out parts 2, thus realizes the welding for main grid, and other regions blocking due to baffle plate 1, infrared light no longer can be irradiated on solar battery sheet, thus no longer makes solar battery sheet cause decay, there will be no the reduction of the power that dispatches from the factory.In addition, because the shape of general main grid is rectangle, therefore hollow-out parts 2 is also preferably rectangle, the area of hollow-out parts 2 can also be arranged to the area being a bit larger tham main grid, thus better makes infrared light all be irradiated on the position of main grid through hollow-out parts 2.It should be noted that, be preferred version, in actual production, when to-be-welded region is other shapes, hollow-out parts 2 also can be customized to corresponding shape, does not here limit herein.
Preferably, in above-mentioned solar cell auxiliary welding equipment, described baffle plate is corrosion resistant plate or aluminium sheet.These two kinds of baffle plates can effectively completely cut off light through, thus effective protection is formed for the solar cell in infrared welding process, can not decay because of infrared radiation.Certainly, this baffle plate is also not limited in above-mentioned two kinds, the metallic plate of other any types or non-metal board, if can effectively completely cut off light through.
Preferably, in above-mentioned solar cell auxiliary welding equipment, the surface of described baffle plate is provided with infrared Absorption striped.So just can reduce the surface reflectivity of baffle plate, avoid infrared light to be reflected back light fixture for a long time and cause light fixture aging.
A kind of solar cell welding method that the embodiment of the present application provides as shown in Figure 2, the flow chart of a kind of solar cell welding method that Fig. 2 provides for the embodiment of the present application.The method comprises the steps:

S2: carry out Infrared irradiation above described baffle plate, utilizes the infrared light through described hollow-out parts to weld described to-be-welded region.
Concrete, to-be-welded region is heated to about 180 ~ 250 DEG C by infrared light hollow-out parts, guarantees that welding completes.Because the region beyond to-be-welded region utilizes baffle plate to stop, therefore infrared light can not be irradiated to the solar cell of baffle plate bottom, and therefore solar cell can not produce decay because of infrared light again.
The above-mentioned solar cell welding method that the embodiment of the present application provides, the surface coverage being included in solar cell is provided with the baffle plate of the hollow-out parts corresponding with the position of to-be-welded region; Infrared irradiation is carried out above described baffle plate, the infrared light through described hollow-out parts is utilized to weld described to-be-welded region, so just make region beyond to-be-welded region not by Infrared irradiation, avoid battery to produce decay, the power that dispatches from the factory of Assurance component.
Preferably, in above-mentioned solar cell welding method, infrared generator is utilized to carry out Infrared irradiation above described baffle plate.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
