[0002] Hydrogen energy, as an ideal clean energy source, has enormous potential. Water electrolysis is a green method for producing hydrogen, and PEM (Polymer Electrolysis Membrane) water electrolysis is considered the most promising hydrogen production technology due to its high electrolysis efficiency, high power fluctuation matching degree, and high hydrogen purity. In a PEM water electrolysis device, the PEM electrolyzer consists of several electrolyzers connected in series. The main components of the electrolyzer include membrane electrodes and plates. Current assembly processes involve repeatedly stacking membrane electrodes, plates, and other modules layer by layer to form a PEM electrolyzer structure containing multiple electrolyzers.

However, since electrode plates and membrane electrodes are of different sizes, different suction cup structures are required for picking up and feeding them. In other words, a set of robotic arms needs to be equipped with multiple sets of suction cups, which not only increases production costs but also affects assembly efficiency. Utility Model Content

The movable plate 6 slides up and down with the guide shaft 4 through the bushing 3. The number of buffers is designed according to needs, generally one buffer is symmetrically placed at each of the four corners of the movable plate 6 to ensure that the movable plate 6 moves smoothly under the drive of the drive device 2.

[0035] Furthermore, the combined suction device also includes a vacuum generator 5; the vacuum generator 5 is installed on the movable plate 6 and is connected to the electrode suction cup 7 through a second air pipe to provide suction for the electrode suction cup 7.

[0038] This embodiment provides a combined suction device, including a fixed bracket 1, a telescopic cylinder, a movable plate 6, a base plate 8, a membrane electrode suction cup assembly, and multiple paper-separating suction cups 9.

[0039] The fixed bracket 1 includes a fixed plate and two symmetrically arranged side plates. One end of each side plate is connected to the bottom surface of the fixed plate, and the other end is connected to the top surface of the base plate 8. A movable plate 6 is positioned between the base plate 8 and the fixed plate. A telescopic air pipe is mounted on the fixed plate, and its piston rod is connected to the movable plate 6. A bushing 3 is symmetrically located at each of the four corners of the fixed plate. A guide shaft 4 is located inside each bushing 3, and one end of the guide shaft 4 is connected to the movable plate 6.
