Compared with previous mechanism requirements, the series welding machine adopts a multi-point linkage and high-precision temperature control system, an original infrared lamp tube heating unit is used as a whole to control temperature rise, and the temperature rise is controlled; and four units are upgraded to independently control the temperature rise.
Description
technical field [0001] The invention relates to the technical field of multi-busbar string welding technology of solar cells, in particular to a multi-point linkage, high-precision temperature control system and method for a string welding machine. Background technique [0002] In the existing battery multi-busbar string welding process, the light box adopts the short-wave infrared lamp to heat up instantly, detects the surface temperature of the battery through an infrared temperature control sensor, feeds the signal to the PLC in real time, and controls the short-wave infrared through the PID command of the PLC. The temperature rise of the lamp; [0003] However, in order to achieve the effect of multi-busbar string welding of cells, it is necessary to ensure that the temperature difference of the cells in the effective heating area of the light box is controlled within 3 °C, and the temperature rise time is short, thereby reducing the welding ribbon and cells. Welding, ...
