Problems solved by technology
[0003] At present, the main welding equipment on the market also uses ceramic pressure needles to compress the welding ribbon and the battery sheet. For example, the patent No. 201210115790.9, the compression welding ribbon provided in the patent named the pressing device for the welding head of the solar cell series welding And the pressing pin of solar crystalline silicon cells, the pressing pin adopts a cylindrical structure. When the working efficiency of the welding head is high, the flux will crystallize at the end of the pressing pin, and the welding of the battery will leave a large Welding marks affect the welding effect and quality of the cell

A welding strip and battery piece pressing device for a solar battery piece series welding head comprises a balance weight sleeve and a pressing needle. The balance weight sleeve is of a hollow cylinder structure. The two ends of the pressing needle are of a V-shaped strip structure. One end of the balance weight sleeve penetrates into a welding head base plate, and the other end of the balance weight sleeve penetrates into a welding head base. One end of the pressing needle penetrates into an O-shaped rubber ring, penetrates into the balance weight sleeve from the bottom of the welding head base and is fixed relative to the balance weight sleeve. The other end of the pressing needle remains outside the balance weight sleeve. When solar battery pieces are welded, a welding strip and the battery pieces are tightly pressed by the pressing needle and the balance weight sleeve, and the strip direction of the pressing needle is perpendicular to the laying direction of main grid lines of the battery pieces. By the adoption of the welding strip and battery piece pressing device, the contact area between the pressing needle and the welding strip and the contact area between the pressing needle and the battery pieces can be reduced, and a welding effect and welding quality can be well guaranteed.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a welding ribbon for a solar cell string welding head and a cell pressing device. Background technique [0002] With the global warming, the calls for clean energy are increasingly strong at home and abroad, and the increase in subsidies for clean energy in various countries has prompted the development of fully automatic stringers for photovoltaic modules. The automatic serial welding machine has fast speed, good quality consistency, beautiful surface, no uneven soldering phenomenon of manual welding, and can reduce the number of operators and inspectors, reduce management difficulty and product cost, and the welding reliability is much greater than that of Advantages such as manual welding. [0003] At present, the main welding equipment on the market also uses ceramic pressure needles to compress the welding ribbon and the battery sheet. For example, the patent No. 201210115...
