Description

Technical Field

[0001] This utility model relates to the technical field of battery transfer production equipment, specifically to a hot rolling composite device for battery proton exchange membrane transfer production. Background Technology

[0002] The proton exchange membrane (PEM) is the core component of a proton exchange membrane fuel cell (PEM fuel cell) and plays a crucial role in its performance. It not only acts as a barrier but also conducts protons. The hydrogen fuel cell PEM consists of a proton exchange membrane, an anode catalyst coating, and a cathode catalyst coating. Traditional manufacturing processes primarily utilize coating techniques. However, due to the swelling characteristics of the proton exchange membrane, the lack of a protective film during the second coating process makes it particularly prone to swelling, wrinkling, and damage.

[0003] In the prior art, Chinese Patent Publication No. CN220763832U discloses a rolling composite device for proton exchange membranes, including: a receiving mechanism, a transfer mechanism disposed at the bottom of the receiving mechanism, and adjustment mechanisms disposed on both sides of the transfer mechanism; the receiving mechanism includes: a feeding trough, a receiving shaft disposed at the bottom of the feeding trough, and a power component for providing power to the receiving shaft; the feeding trough is arranged in an inverted V-shape with a small bottom opening; there are also two receiving shafts; the transfer mechanism includes: a transfer shaft, an extrusion shaft disposed on one side of the transfer shaft, and a transmission component fixedly connected to one side of the transfer shaft and the extrusion shaft; the transfer shaft and the extrusion shaft are disposed directly below the receiving shaft; the adjustment mechanism includes: an L-shaped plate, and an adjustment component disposed on one side of the L-shaped plate; the adjustment component is used to push the extrusion shaft to move; the L-shaped plate is fixedly connected to the extrusion shaft; this allows the pressure value to be adjusted according to different types of proton exchange membranes during the transfer process, thereby improving the yield of proton exchange membranes. However, the adjustment mechanism in the aforementioned proton exchange membrane rolling composite equipment has low sensitivity to the adjustment pressure value, making it impossible to achieve precise control of the composite pressure and also impossible to achieve multi-functional and multi-path composite transfer of proton exchange membranes. Therefore, improvements are needed. Utility Model Content
