Description
Technical field
The utility model relates to a kind of welder of solar panel, relates to a kind of invention weaving banding pattern solar cell photovoltaic welding aspect or rather.
Background technology
Photovoltaic welding belt is the welder be used on photovoltaic module, mainly plays the effect connecting conduction.The critical technical parameter of welding device comprises solderability, tensile strength, elongation, resistivity.Welding device conventional is at present the copper strip surface at a kind of high-elongation, high tensile, high connductivity, and the method being coated with tin by heat is prepared from.Along with the raising of solar panel transformation efficiency, increasing by the electric current of welding inside, therefore just require that the conductive area of welding constantly increases, but along with the increase of welding thickness, the flexibility of welding is also in reduction, and the welding after simultaneously thickening can bring larger thermal stress to cell piece, causes the probability of cell piece breakage to increase, therefore the welding proposing a kind of high flexibility, high connductivity area is needed, to solve the problem in current solar-photovoltaic technology field.
As can be seen here, above-mentioned existing welding device still has many defects, needs to be improved.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing welding device exists, and provides a kind of braiding banding pattern solar cell photovoltaic welding.
The utility model solves its technical problem underlying and realizes by the following technical solutions.According to the braiding banding pattern solar cell photovoltaic welding that the utility model proposes, comprise the belt body of longitudinal extension, belt body comprises conductor wire, solder stick and litzendraht wire, described conductor wire is arranged in parallel at long axis direction, the angle that the long axis direction of described litzendraht wire and belt body is is acute angle, described litzendraht wire intert belt body cross section and share split is carried out to conductor wire, the litzendraht wire of adjacent intersection is tied up conductor wire, described solder stick be parallel to belt body and be positioned at band surface.
Better, above-mentioned conductor wire is made up of conductive filament.
Better, by conductive filament, arranged in parallel or strand system forms above-mentioned conductor wire.
Better, above-mentioned litzendraht wire is filament, and the diameter of filament is 0. 1 millimeters to 1 millimeter.
Better, the diameter of above-mentioned conductive filament is 0.01 millimeter to 0.1 millimeter.
Better, the cross sectional dimensions scope of above-mentioned solder stick is 0. 1 millimeters to 1 millimeter.
Better, the cross section of above-mentioned solder stick is the one in circular, oval, trapezoidal, rectangle or square.
Better, above-mentioned solder stick is distributed in the two sides of two broadsides of belt body, and there are at least two solder sticks on the surface of each, and described solder stick is fastened on the surface of belt body by litzendraht wire.
Better, the conductor wire guaranteeing to be tied is staggered at next bundling position by share split again mutually along the axis direction of belt body in the above-mentioned litzendraht wire adjacent position of tying up conductor wire.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme, the utility model brings multiple advantage owing to adopting technique scheme, first, adopts conductor wire and litzendraht wire composition braid over braid, is evaded the rigidity of current welding by the flexibility of braid over braid; Secondly, braid over braid is at the position of weld with solar panel, and owing to being the welding of conductor wire and solar panel, the pliability of conductor wire can reduce the thermal stress being applied to solar panel, the risk that reduction solar panel breaks; Again, the trend of conductor wire is mainly along the long axis direction of belt body, the boundling of conductor wire mainly relies on litzendraht wire to complete with tying up, because litzendraht wire is more tiny than conductor wire far away, therefore, from electrical efficiency, only have little wire important in the direction of belt long axis of body, which improves the electrical efficiency of material; Again, compare traditional welding, the utility model structure do not have hot tinning layer, and using the solder stick preset as welding material, decrease production process and energy consumption, too increase the flexibility of product simultaneously, that is, can according to different client need change the material of solder stick and diameter, but very little to the change of production technology, reduce cost; Finally, the utility model provides the ductility that braiding banding pattern welding has certain vertical and horizontal, is conducive to erecting and welding.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, technological means of the present utility model is better understood for enabling professional and technical personnel, and can be implemented according to the content of specification, coordinate accompanying drawing to be described in detail as follows with preferred embodiment of the present utility model below.
