Description

Technical Field

[0001] The invention relates to the field of photovoltaic technology, and in particular to a photovoltaic welding ribbon for a photovoltaic module. Background Art

[0002] The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module. The welding ribbon must be firmly welded in the process of connecting the battery cells in series to avoid the occurrence of false welding. When selecting the welding ribbon, the manufacturer must decide what state of the welding ribbon to use based on the characteristics of the selected battery cell.

[0003] When welding existing photovoltaic modules, it is necessary to splice the photovoltaic panels or brackets together, and then use welding tape to align the weld for welding. However, during welding, the welding tape and welding points need to be manually calibrated and straightened, which not only increases the difficulty and intensity of the welding work for one person, but is also not conducive to maintaining the accuracy of the welding tape after welding and the fit between the welding tape and the photovoltaic module. For this reason, a photovoltaic welding tape for photovoltaic modules is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when welding existing photovoltaic modules, photovoltaic panels or brackets need to be spliced ​​together, and then welding is carried out using welding tapes to align the welds. However, during welding, the welding tapes and welding points need to be manually calibrated and straightened, which not only increases the difficulty and intensity of the welding work for one person, but is also not conducive to maintaining the accuracy of the welding tape after welding and the fit between the welding tape and the photovoltaic module. The present invention provides a photovoltaic welding tape for a photovoltaic module.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0009] Furthermore, the same protective film is fixedly installed on the top of the welding ribbon base and the positioning cap, and the protective film is fixedly installed on the top of the aluminum base layer, and the protective film is made of transparent material.

[0010] Furthermore, the protective assembly includes a protective belt arranged on the top of the welding tape base, the protective belt corresponds to the positions of the positioning groove and the positioning convex strip, and one side of the protective belt is fixedly installed on the top of the welding tape base.

[0011] Furthermore, an inserting strip is fixedly mounted on the bottom of one side of the protection strip away from the soldering strip base, and a slot corresponding to the position of the inserting strip is opened on the top of the soldering strip base.

[0012] Furthermore, a plurality of evenly distributed reflective caps are fixedly mounted on the top of the protection belt.

[0013] Furthermore, a plurality of evenly distributed welding feet are provided on both sides of the welding tape base, and stepped welding grooves are provided on both sides of the welding tape base.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention aligns the positioning convex strip with the joint of the photovoltaic module, then wraps the module with the welding tape base, and then overlaps the welding tape base with the head and tail, and uses the positioning component to wrap the welding tape base on the joint of the photovoltaic module to be welded, so as to realize automatic calibration and straightening of the welding tape base and the photovoltaic module, which not only facilitates the single-person welding operation, but also ensures the welding quality, so that the welding tape base can be more closely fitted to the joint of the photovoltaic module;

[0016] 2. When welding, the present invention can be aligned with the positioning groove for welding, so that the positioning convex strip is heated and melted to penetrate into the joint of the photovoltaic module, thereby improving the connection strength between the welding tape base and the photovoltaic module.

The positioning cap made of the aluminum base layer can not only have a higher tensile resistance during positioning, but also can reflect the light beam irradiated on the positioning cap to the surroundings after welding, thereby increasing the light absorption area of ​​the photovoltaic panel.
