A person or a handling robot places a piece of film material on the adsorption plate 24 and opens the corresponding control valve; a person places another piece of film material on the screen 31 and opens the corresponding control valve. The adsorption plate 24 flips 180°, the mesh box body 30 moves to the bonding position below the adsorption plate 24, and the adsorption plate 24 drops to a suitable height; the lifting cylinder 35 lifts the pressure roller 34 and starts rolling from one end of the film. After the rolling is completed, the pressure roller 34 drops, the adsorption plate 24 rises, and the mesh box body 30 moves out of the bonding position to complete the bonding of the two layers of film. Repeat the above actions to complete the bonding of multiple membrane electrodes.
