Welding device and processing method for electrical connecting piece

The invention relates to the technical field of electronic element manufacturing. A welding device for an electrical connecting piece is characterized by comprising a frame and an index plate device thereof, as well as a connecting-base conveying device, a first welding-male-tab conveying device, a first welding-male-tab assembling device, a welding device, an inspecting device and a discharging device, wherein the index plate device comprises an index plate and an index-plate driving component which drives the index plate to rotate; and a plurality of jig components are arranged on the outerring of the index plate regularly in the circumferential direction. The welding device and the processing method have the advantages of improving the fitness between a jig and a connecting base, preventing the connecting base from detaching, and improving the conveying accuracy and efficiency of the connecting base, the assembling efficiency and quality of a welding male tab, and the welding efficiency and quality of the
