The present invention discloses a battery cell insulation strip laying and welding integrated machine and welding method, the welding integrated machine comprises a machine body, and an introduction and correction device, a material feeding and welding device, a battery cell lifting device, and an insulation strip feeding device fixed on the machine body, the battery cell lifting device, the insulation strip feeding device, and the feeding and welding device are respectively located above the introduction and correction device, the introduction and correction device is provided with multiple groups of opposing laser sensors, and the battery cell is located between the transmitting end and the receiving end of the multiple groups of the opposing laser sensors. The present invention can avoid laying and welding the insulation strip when the EVA film and the bus bar are adhered together, and avoid the occurrence of defective products.

The invention relates to the technical field of diffusion plate production, in particular to a diffusion plate welding and attaching production method and device.The diffusion plate welding and attaching production method comprises the following steps of S1, feeding, S2, double-face dust removal, S3, welding and attaching, S4, AOI detection and S5, film covering and blanking.The full-automatic production process is introduced, seamless connection from feeding to discharging is achieved, and the production efficiency is improved; a plurality of problems in a traditional production method are effectively solved, in the feeding link, the multiple lifters and the multiple manipulators are arranged to suck different plates at the same time, the feeding efficiency is remarkably improved, the waiting time is shortened, and the overall production speed is increased. The double-face dust removal device can effectively remove dust and static electricity on the surface of a plate through a rubber roller and an ion wind bar, a clean surface condition is provided for follow-up welding, the welding quality is ensured, the position precision of the plate in the welding process is ensured through accurate positioning and photographing correction of the welding attaching device, and the welding quality is improved. And poor welding caused by position deviation is avoided.
