Description

Technical Field

[0001] The present invention relates to the technical field of measuring equipment, in particular to a hydrogen energy film thickness measuring device. Background Art

[0002] The performance of fuel cells has a great impact on the power supply of batteries. At this stage of research, the research efforts on hydrogen fuel cells are the greatest. Hydrogen fuel cells are a recognized environmentally friendly and pollution-free energy source. In order to improve the performance of hydrogen energy fuel cells, PEN polymer films are generally used. The hydrogen energy film needs to be measured for thickness during the production process. It can only be mass-produced if it meets the standards. When the equipment used for measurement (such as a film thickness gauge) is working, the film needs to be laid on the workbench, then covered on the circular support, and pressed tightly by the test presser foot. However, this type of equipment needs to check different positions of the film multiple times when working, which requires the tester to manually move the film to change the measurement point. This process is relatively cumbersome, especially when it is necessary to measure a long film sample. The problem is more prominent. For this reason, we propose a hydrogen energy film thickness measurement device. Summary of the invention

When one shaft 3 59 is rotated, the synchronous pulley 66 cooperates with the synchronous belt to drive the other shaft 3 59 to rotate synchronously.

[0054] One end of a shaft three 59 is fixedly connected to a gear plate two 67 meshing with the gear plate one 54 , and the drive motor 55 is started to drive the gear plate one 54 to rotate, thereby driving the gear plate two 67 to rotate, and then driving the two shafts three 59 to rotate.
