Welding belt bonding device of solar module

Abstract

The invention relates to a welding belt bonding device of a solar module, comprising a loading machine which clamps and leads out the welding belt supplied by a welding belt supply portion, enabling the welding belt to pass the upper part of a solar cell, and a heating bonding portion which is provided with a plurality of first pins in the bottom to prevent the led-out welding belt from displacing under the state of clamping release. The welding belt under the state of clamping release is fixed and bonded to the solar cell by means of the first pins and a plurality of second pins protruding the bottom face. The welding belt is fixed to a bus of the solar cell by means of pins whose height of the tail ends are shorter among all the pins, and a component enabling the welding belt to completely disengage from a clamp is provided. Therefore, the position of the welding belt can be prevented from changing and bonding can be conducted at a correct position. The effect of preventing the solar module from having a low efficiency and preventing the service lifetime from being shortened can be achieved.

Description

technical field [0001] The invention relates to a welding ribbon bonding device for a solar module, in particular to a device that can prevent the welding ribbon from swaying when the welding ribbon is loaded on the upper part of the solar battery sheet, and prevent the welding ribbon from being welded to the solar module of the loader from sticking. knot device. Background technique [0002] Generally, solar cells used for solar power generation can generate electricity when they are in the form of solar cells based on silicon materials or various compounds. However, since sufficient power cannot be obtained with one cell, it is necessary to connect each cell in series or in parallel, and the solar cells connected in this way are called "solar modules." [0003] A solar module is composed of a back sheet, solar cells, ribbon, ethylene-vinyl acetate copolymer (EVA), and glass. The backplane is the material at the bottom of the module, and polyvinyl fluoride composite film ...

Problems solved by technology

[0013] However, when the heating bonding part 4 is moved downward for bonding after the ribbon R is removed from the clamp 6, the position of the ribbon R during the process of removing the ribbon R from the clamp 6 may change. change, so there is a problem that the ribbon R cannot be bonded at the exact position

[0014] The welding ribbon R should be accurately placed on the bus line arranged on the upper part of the solar battery sheet 3. When the welding ribbon R is inconsistent with the bus line, the problems of low efficiency and shortened life of the solar battery sheet will be caused.

[0015] In addition, after bonding the above-mentioned ribbon R, the ribbon R is separated from the tongs 6, and the heated ribbon R is fused to the tongs 6, making it difficult to separate, or the tongs 6 leave a residue of the ribbon R. object, so that a good clamping of the ribbon R cannot be formed afterwards

[0016] At the same time, in the existing ribbon bonding device for solar modules, the distance from the ribbon supply part 1 for supplying the ribbon to the heating bonding part 4 is fixed, so it is difficult to apply it to solar modules in other application fields. Adhesive Ribbon on Module

[0017] That is, compared with the spacing between the solar cells of the usual solar module, the distance between the solar cells of the solar module suitable for glass windows or building integrated photovoltaic (Building Integrated Photovoltaic System) is larger, so as to improve the transparency. However, the position of the heating bonding part 4 of the ribbon bonding device of the existing solar module is fixed, so it cannot be applied to solar modules with various spacings between solar cells
