The humidity control of the cathode air intake of the fuel cell mainly adopts a humidifier. The structure of the hydrogen fuel cell humidifier is a fuel cell humidifier disclosed in Patent Publication No. CN113871648B, which includes a shell, a plurality of hollow fiber membranes are arranged in the shell, and a colloid injected into the shell and fixes the hollow fiber membranes. This process is called a potting process. After the hydrogen fuel cell humidifier filter membrane is formed, it is necessary to cut the rubber heads on its two end faces to expose the filter holes. The cutting in the prior art is done by manually holding a blade, and the quality of the cut surface is poor, the cutting effect is not good, and it is easy to cause the fuel cell humidifier to be defective.

[0003] At present, our company has developed an automatic cutting equipment to realize automatic cutting of the filter membrane of the hydrogen fuel cell humidifier. However, since the fuel cell humidifier is heavy, if the sampling is done manually, it is easy to cause operator fatigue on the one hand, and on the other hand, the manual operation efficiency is low, and the positioning of the fuel cell humidifier is easy to be inaccurate during loading, resulting in poor cutting problems; and the subsequent fuel cell humidifier must be placed in an air shower room for automatic dust removal. These manual operations cannot meet the needs of large-scale efficient production.

[0004] Therefore, it is necessary to develop an automatic cutting system for sealing the filter membrane of a hydrogen fuel cell humidifier to solve the above problems. [Contents of the utility model]

[0009] Furthermore, two pneumatic clamping modules are provided, which are symmetrically distributed on both sides of the clamping module.

[0010] Furthermore, the support clamp is L-shaped as a whole and is formed with a blocking surface for blocking the end surface of the hole of the fuel cell humidifier and a supporting surface for abutting against the inner wall of the hole of the fuel cell humidifier.
