The current bus bar welding technology is that before welding, the battery strings are arranged on glass, after aligning to the positions on the graduated scale, the battery strings are fixed on the glass by manual tape, and then are transmitted to a welding station together through a transmission line. This highlights the effect of human factors on the product; and twelve strings of battery strings are fixed on 2 m glass, a large amount of adhesive tapes are required to be adhered for fixation, and the manual efficiency is low; the battery strings fixed by the adhesive tape have poor stability, are easy to misplace in the transmission process, and influence the performance of welded products.
The bus bar welding process of the half-piece battery string needs to be carried out at three positions of two ends and the middle position of the glass, and a backing plate needs to be paved between the glass and the battery string welding strip at the three positions before welding, so that the damage to the glass in the welding process is protected, and the backing plate is fixed by an adhesive tape. After the welding is finished, the adhesive tape is manually torn off, the backing plate is required to be withdrawn, the backing plate withdrawal can not be finished by the integrated mechanism on the welding equipment at present, and the increased manual work greatly influences the welding efficiency.
Bus bar welding machines developed by some manufacturers are used for welding bus bars of whole battery strings; for welding of half-cell strings, the developed machine type can only perform the welding procedure, and the rest of the processes are required to be completed manually.
