Abstract

The invention discloses bipolar plate laser hybrid welding equipment for a hydrogen fuel cell. The bipolar plate laser hybrid welding equipment comprises a cabinet base, a protection cabinet, a cabinet door, a marble platform, a first marble portal frame, a first Y-axis linear module, a jig for fixing a bipolar plate, a second Y-axis linear module, a first X-axis linear module, a Z-axis linear module, a collimation laser welding head, a second portal frame, a second X-axis linear module, an optical fiber laser and a laser scanning galvanometer. A light outlet of the laser scanning galvanometer is vertically downward, and emitted laser is perpendicular to the upper end face of the bipolar plate on the jig. Compared with the prior art, high-efficiency machining of the bipolar plate can be achieved, and the laser welding yield of the bipolar plate can be remarkably increased.

Description

technical field [0001] The invention relates to the technical field of cutting equipment for printed circuit boards, in particular to a bipolar plate laser composite welding equipment for hydrogen fuel cells. Background technique [0002] The bipolar plate is an important part of the hydrogen fuel cell, which plays the role of current collection, gas distribution, water management and thermal management. The manufacturing process of the bipolar plate is generally to first make the anode and cathode flow field plates with thin metal plates (thickness 0.1mm), and then connect the two together to form a coolant flow channel between the two plates. The sealing requirements of the bipolar plate are very high. If the sealing is not good, the reaction substances and cooling liquid may leak, which will reduce the performance of the battery or lose its function. At present, the processing method of connecting anode and cathode adopts welding method. Compared with other connection pr...
