Abstract
The invention discloses a series welding machine and battery piece series welding method of dual welding stations. The series welding machine comprises a metal net frame, a welding device, a conveyingdevice and a rack. The welding device is mounted on the rack and erected above the conveying device. The conveying device is used for conveying a battery piece. The welding device comprises a first welding unit, a second welding unit and a welding frame. The first welding unit is used for welding a welding strip on the back face of the battery piece and heating the battery piece so as to improvethe welding takt. The metal net frame is used for fixing a welding strip on the front face of the battery piece. The second welding unit is used for welding the welding strip, fixed by the metal net frame, on the front face of the battery piece. Meanwhile, the battery piece series welding method achieved through the series welding machine of the dual welding stations is provided. The two welding stations are arranged and used for welding the front face and the back face of the battery piece correspondingly. According to the series welding machine and battery piece series welding method of thedual welding stations, the problem of welding deviation of the welding strips on the front face and the back face of the battery piece is solved, the welding effect of multi-main-grid battery pieces is guaranteed, and the welding quality is improved.
Description
technical field [0001] The invention relates to the technical field of solar cell manufacturing, in particular to a double-station stringer and a cell stringer method. Background technique [0002] The development of human beings is inseparable from energy. With the rapid development of the economy, the demand for energy continues to increase. As a new energy source that directly converts sunlight into electrical energy, the proportion of solar cells in energy demand will become higher and higher. [0003] Currently, the mainstream crystalline silicon solar cell modules on the market generally have three busbar lines. In recent years, in order to improve the efficiency of solar cells and reduce costs, battery manufacturers have increased the main grid from 3 grids to 4 grids, or even 5 grids from the perspective of improving efficiency. With the development of technology, multi-busbar technology has emerged, that is, printing multiple busbars (generally 10-20 busbars) on th...
