Series welding device for back contacting solar cell

The utility model discloses a series welding device for back contacting solar cells. The series welding device is suitable for back contacting solar cells, of which the negative and positive extraction electrodes, and comprises five modules which are respectively a welding band dismounting and rolling module, a charging workbench, a cell chip bonding module, a welding band cutting module and a traction module. The work steps of the series welding device includes a fixing and tightening the welding band by the welding band dismounting and rolling and traction modules, sending cell sheets to welding positions by the charging workbench, aligning, parallelly welding electrodes and the welding band, and cutting superfluous weld band. The series welding device is high in aligning precision, rapid in welding speed, simple in work flow and easy for realizing automation.
