Abstract: The present disclosure relates to a processing apparatus for a secondary battery current collector. The processing apparatus includes: a foil uncoiling roller; a composite current collector uncoiling roller; a welding device; a plurality of driving rollers; and a coiling roller. Both the foil uncoiling roller and the composite current collector uncoiling roller are disposed on a feeding side of the welding device. The welding device is configured to weld foil to a portion of a composite current collector. The plurality of driving rollers is respectively disposed on a feeding side and a discharging side of the welding device, and has an equal line speed. The plurality of driving rollers is configured to drive the overlapped foil and the composite current collector to downstream. The coiling roller is configured to wind up the composite current collector having the foil welded thereon.
