Abstract
The utility model relates to a novel photovoltaic welding strip device for a solar battery. The novel photovoltaic welding strip device comprises a longitudinally extended strip body, the strip body comprises a copper strip, a tin layer is coated on the outer side of the copper strip, and a layer of copper strip is arranged on an L-shaped bend of the novel photovoltaic welding strip device for the solar battery. During welding operation and long-term use, the novel photovoltaic welding strip device for the solar battery can avoid the possibility of pseudo soldering and improve the stability of the solar battery.
Description
Technical field
The utility model relates to a kind of welder of used for solar batteries, relates to the invention of a kind of novel solar battery photovoltaic welding belt device aspect or rather.
Background technology
Solar cell photovoltaic welding device is the welder that is used on the photovoltaic module, mainly plays the effect that connects conduction.The critical technical parameter of welding device comprises solderability, tensile strength, elongation, resistivity.Welding device commonly used at present is that the method that is coated with tin through heat is prepared from the copper strip surface of a kind of high-elongation, high tensile, high conduction.Often in the solar cell connection procedure, the position, right angle of L type can appear in the welding device, and the processing method of prior art is two photovoltaic welding belt devices to be 90 degree put, and two is overlapped, welds then.The method that prior art is handled welding device L type rotation angle position often causes the overlapping part rosin joint easily; And in the overlapping region owing to touch the difference of electric soldering bit distance; Welding unit temp height can occur, and welding unit temp below is low, two welding devices welding mutually under different temperatures near electric soldering bit; Directly cause after cooling, overlapping part has residual stress.The method of handling welding device L type rotation angle position like Fig. 1 prior art is that two of two weldings is overlapped; Weld; Will form at overlapping part 2 that each parts are coated with tin layer 12, copper strips 11, are coated with tin layer 12 like this, copper strips 11, be coated with the sandwich structure of tin layer 12, the cross section structure after overlapping part 2 welding is asked for an interview Fig. 1.This structure causes the generation of rosin joint easily, and between two-layer welding, produces stress, and the photovoltaic welding belt device is in the operating state of sun direct projection for a long time, and residual stress causes sealing-off the most at last and the solar cell that is connected is opened circuit.The generation of residual stress and rosin joint all can have a strong impact on the sex work steady in a long-term of solar cell.
This shows that above-mentioned existing welding device still has many defectives, and demands urgently improving.
Because the defective that above-mentioned existing welding device exists; The design people is based on being engaged in this type of product design manufacturing for many years; Long-pending have abundant practical experience and professional knowledge, actively studies innovation, in the hope of founding a kind of novel solar battery photovoltaic welding belt device that improves molding structure; Can improve the general molding structure of existing conventional welding device on the market, make it have more competitiveness.Through constantly research, design, and after studying sample and improvement repeatedly, found out the utility model of true tool practical value finally.
Summary of the invention
The utility model technical problem underlying to be solved is; Overcome the defective that existing welding device exists; And a kind of solar cell photovoltaic welding device of new structure is provided; Overcome rosin joint appears in existing solar cell photovoltaic welding device at position, L type right angle defective, make it reduce the rosin joint probability that occurs in the overlapping welding process at position, L type right angle, improve the reliability of solar module.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.According to the novel solar battery photovoltaic welding belt device that the utility model proposes, comprise the belt body of longitudinal extension, belt body comprises copper strips, is provided with in the copper strips outside and is coated with the tin layer, novel solar battery photovoltaic welding belt device has only one deck copper strips at L shaped turning.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before the thickness of described copper strips be 50 microns to 350 microns.
Before the described thickness that is coated with the tin layer be 10 microns to 50 microns.
The utility model compared with prior art has tangible advantage and beneficial effect.Can know that by above technical scheme the utility model is owing to adopt technique scheme that one monoblock Copper Foil is produced the copper strips that comprises L shaped turning site according to the layout of solar cell through the method for punching press, and then carry out heat and be coated with tin; Perhaps Copper Foil is carried out heat earlier and be coated with tin, punching press then, the novel solar battery photovoltaic welding belt device of producing has so just avoided L shaped turning site to need the situation of two overlapped welding of welding.Meanwhile, the solderability of welding device is good, tensile strength is high, and elongation and resistivity all can fully satisfy the practical applications needs, has reached the purpose of the utility model design.
Above-mentioned explanation is merely the general introduction partly of the utility model technical scheme characteristic; For making the professional and technical personnel can more know the technological means of understanding the utility model; And can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.
The embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the cross section structure sketch map of existing welding device at L type rotation angle position.
Fig. 2 is the schematic top plan view of the utility model.
Among the figure, belt body 1, copper strips 11, be coated with tin layer 12, overlapping part 2.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also shown in Figure 2; The novel solar battery photovoltaic welding belt device of the utility model is produced the copper strips that comprises L type turning site according to the layout of applied solar cell through the method for punching press, and then carries out heat and be coated with tin and form and to be coated with the tin layer; Perhaps carry out Copper Foil heat earlier and be coated with tin; Carry out punching press then, like this at place, L type turning site, the turning site of just adjacent two each other vertical belt bodies 1 has only one deck copper strips; The thickness of copper strips is 50 microns to 350 microns, and the thickness that is coated with the tin layer is 10 microns to 50 microns.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
