Description

Technical Field

[0001] The utility model relates to the technical field of spraying, in particular to automatic spraying equipment for proton exchange membranes. Background Art

[0002] Proton exchange membrane, also known as proton membrane or hydrogen ion exchange membrane, is an ion-selective permeable membrane that provides channels for proton migration and transmission, separates gas reactants and blocks electrolytes in batteries. It has high proton conductivity, good mechanical and thermal stability, low gas permeability and chemical compatibility with other battery components. It is the core component of proton exchange membrane fuel cells.

[0003] When optimizing the existing automatic spraying equipment for proton exchange membranes, most of the optimization focuses on improving production efficiency and enhancing spraying quality. For example, the Chinese utility model patent with application number CN201921037784.X discloses "Automatic Spraying Equipment for Proton Exchange Membrane". In this device, by adding a first moving mechanism and a second moving mechanism, the spray tray on which the automatic spraying equipment for proton exchange membranes is placed moves on the spraying platform, and the moving paths of several spray trays are parallel to each other; the spray gun can spray the exchange membranes in the spray trays on multiple moving paths, thereby realizing the batch, synchronous, and streamlined spraying of several base membranes on the same surface, improving production efficiency and enhancing spraying quality.

[0004] Although the above-mentioned proton exchange membrane automatic spraying equipment has certain advantages in improving production efficiency and enhancing spraying quality, it still has certain disadvantages: since the carrier plate on which the exchange membrane is placed is fixed in position, exchange membrane parts of different specifications can only be partially sprayed during the spraying process and cannot be sprayed fully. In addition, the position of the spray gun is fixed and the height position of the exchange membrane part cannot be adjusted, resulting in different spraying efficiencies of exchange membrane parts of different specifications.
