Compared with the prior art, the novel photovoltaic welding strip device of the solar cell provided by the utility model is adapted to weld the solar cell in the manner of non-full-contact with main grid lines, that is to say, only the welding strip part needs to be welded with the main grid lines of the solar cell, stress in cold and hot circulations after the welding strip is welded with the solar cell can be effectively reduced, the number of times of cold and hot circulations is increased, the number of anti-fatigue times during working of assemblies is increased, and the service life of the solar cell assemblies is prolonged.
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; Owing to will stand the long-term radiation of sunlight equally as the significant components of solar cell; Also will stand simultaneously the variations in temperature of 24 hours intercycle property, solar cell photovoltaic welding device all has very high requirement at the selection of conductive strips, the prescription of scolding tin, the aspects such as yield strength of welding.Solar cell photovoltaic welding device mainly plays the effect that connects conduction.The critical technical parameter of welding device comprises solderability, yield strength, tensile strength, elongation, resistivity.Welding device commonly used at present is the copper strip surface at a kind of low yield strength, high-elongation, high tensile, high conductivity, and the method that is coated with tin through heat is prepared from.Because assembly is in the cold cycling at daytime, night for a long time; After photovoltaic welding belt device and the solar battery sheet welding; There is the inconsistent problem of shrinkage; Can produce self stress, arrive that welding device and solar battery sheet pad get loose gradually after certain number of times, cause solar-energy photo-voltaic cell loose contact even open circuit fault to occur.
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, overcomes the defective that existing solar cell photovoltaic welding device exists, and a kind of novel solar battery photovoltaic welding belt device is provided, and its purpose is to improve the unfailing performance of solar module.
To achieve these goals, its technical problem underlying of the utility model solution adopts following technical proposal to realize.According to a kind of 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, in the position of belt body width 1/2nd, the slice space of a series of hollow outs is arranged.
The utility model solves its technical problem and can also adopt following technical measures further to realize.
Before the slice space of described hollow out be parallel to the belt body y direction.
Before the width in slice space of described hollow out be 0.2 millimeter to 2 millimeters, length is 3 millimeters to 30 millimeters, the spacing between the slice space of adjacent hollow out is 5 millimeters to 50 millimeters.
The utility model compared with prior art has tangible advantage and beneficial effect; Can know by above technical scheme; The utility model novel solar battery photovoltaic welding belt device and solar battery sheet weld; Owing to there is the slice space of a hollow out in the middle of the photovoltaic welding belt; In periodicity heat expansion shrinkage process, the deformation of photovoltaic welding belt just can discharge through the slice space of hollow out, and so periodically the stress of heat expansion shrinkage just can not concentrated on the pad that is applied to solar battery sheet.
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 front mounting structure sketch map of the utility model.
Among the figure, the slice space 2 of belt body 1, hollow out, welding position 3, solar cell 4.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.See also Fig. 1.
The utility model solar cell photovoltaic welding device comprises the belt body 1 of longitudinal extension, and belt body comprises copper strips; Outside copper strips, be provided with and be coated with the tin layer,, the slice space 2 of a series of hollow outs is arranged in the position of belt body width 1/2nd; The slice space 2 of hollow out is parallel to belt body 1 y direction; The width in the slice space 2 of hollow out is 0.2 millimeter to 2 millimeters, and length is 3 millimeters to 30 millimeters, and distance is 5 millimeters to 50 millimeters between the adjacent slice space 2.
The belt body 1 of the utility model solar cell photovoltaic welding device covers on two main coral lines of solar cell 4, and the welding position 3 on belt body 1 and the main coral line is discrete a plurality of zone, and the slice space 2 of hollow out is between adjacent welding position 3.
The thermal coefficient of expansion of the thermal coefficient of expansion of copper and the used silicon materials of solar cell differs bigger; Because there is the slice space of a hollow out in the middle not weld of photovoltaic welding belt; In periodicity heat expansion shrinkage process; The deformation of photovoltaic welding belt just can discharge through the slice space of hollow out, and so periodically the stress of heat expansion shrinkage just can not concentrated on the pad that is applied to solar battery sheet, reduced photovoltaic welding belt cross-sectional direction and solar cell because of variations in temperature the stress that produced; Play the effect of protection pad, and then improved the reliability of solar module.
