Abstract

Disclosed is a apparatus for manufacturing pole-piece pockets, comprising a framework, an pole-piece supplying assembly, an pole-piece transporting and regulating assembly, a vertically thermal-welding assembly, a transversely thermal-welding assembly, a film clamping and drawing assembly, and a film cutting assembly for cutting the films. The vertically thermal-welding assembly comprises a press welding cutter having two blades for simultaneously welding the two lateral edges of the pole-piece pocket. The transversely thermal-welding assembly comprises a first thermal welding cutter for welding the base of the pole-piece pocket and a second thermal welding cutter for welding the opening of the pole-piece pocket. The press welding cutter has two blades so that the two lateral edges of a pole-piece pocket can be welded in just one welding operation. Thus, the parallelity and welding consistency of the welding joints can be ensured. Moreover, the welding efficiency and quality are increased, and the risk of malfunction is decreased.
