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 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.Solar module has one side towards sunlight, and one side is attached to above the fixed panel in addition, and two electrodes of solar cell lay respectively on these two faces exactly.In the solar module production process, the situation that adjacent solar battery is connected in series can appear, that is to say; The photovoltaic welding belt that is connected in series has one side to be welded on the one side towards sunlight, and another side is welded on the one side of carrying sunlight, because solar cell has certain thickness; The photovoltaic welding belt device is at the position of corner; Can have a stress at the edge of solar cell, this stress is applied to solar battery edge for a long time, because solar cell itself is extremely thin; Be highly brittle; The stress that the photovoltaic welding belt device applies causes solar cell embrittlement in welding process easily, or through embrittlement behind the long time integration, causes the inefficacy of whole solar cell plate array.
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 novel solar battery photovoltaic welding belt device of new structure is provided, and make it avoid the stress of photovoltaic welding belt in the solar cell panel edges, improve the reliability of solar cell.
The utility model solves its technical problem underlying and adopts following technical scheme to realize.Novel solar battery photovoltaic welding belt device according to the utility model proposition; The belt body that comprises longitudinal extension; Belt body comprises copper strips, is provided with in the copper strips outside and is coated with the tin layer, and the longitudinal section of the belt body of this novel solar battery photovoltaic welding belt device is zigzag; One section one side that is welded on solar cell towards sunlight of zigzag, one section is welded on the one side of solar battery back to sunlight.
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 250 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 by above technical scheme; The utility model is zigzag owing to adopt technique scheme that a bit of belt body is processed its longitudinal section through the method for punching press; Such zigzag just can avoid the corner of photovoltaic welding belt device to touch solar battery edge, has avoided the photovoltaic welding belt device to be applied to the stress of solar battery edge.
In sum, the utility model really belongs to innovation on the kenel of space, and has the multinomial effect of enhancement than existing product, and simple in structure, is suitable for practicality, has the extensive value of industry.It is in limited field, technical development space; No matter structurally or bigger improvement all arranged on the function; And have large improvement technically, and produced handy and practical effect, and have the effect of enhancement really; Thereby being suitable for practicality more, really is the new design of a novelty, progress, practicality.
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 vertical section structure sketch map of the utility model novel solar battery photovoltaic welding belt device.
Among the figure, belt body 1, copper strips 11, be coated with tin layer 12, solar cell 2, solar battery edge 21.
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 1ly, the utility model solar cell photovoltaic welding device comprises the belt body 1 of longitudinal extension; Belt body 1 comprises copper strips 11, is provided with in copper strips 11 outsides and is coated with tin layer 12, and the thickness of copper strips 11 is 50 microns to 250 microns; The thickness that is coated with tin layer 12 is 10 microns to 50 microns; Make its longitudinal section be zigzag the method for belt body 1 through punching press, one section one side that is welded on solar cell 2 towards sunlight of zigzag, one section is welded on solar cell 2 one side of sunlight dorsad; Such zigzag just can avoid the corner of photovoltaic welding belt to touch solar battery edge 21, has avoided photovoltaic welding belt to be applied to the stress of solar battery edge 21.
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.
