Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a cutting device for producing and processing fuel cell carbon paper. Background Art

[0002] Fuel cells, as a leader in the field of clean energy, have the advantages of high efficiency conversion, low pollution emissions, and rapid start-up, and have become an important direction for future energy development. In the core component of fuel cells, the membrane electrode assembly, the gas diffusion layer is an indispensable part, and carbon paper is the key material for preparing the gas diffusion layer. The gas diffusion layer in the fuel cell needs to be customized according to the size and shape of the fuel cell stack or single cell. As the main material of the gas diffusion layer, the size of carbon paper must match that of other components of the fuel cell (such as electrodes, diaphragms, etc.). Therefore, a cutting device is required to process the carbon paper into the required size and shape.

[0003] Some existing fuel cell carbon paper cutting devices lack cleaning mechanisms when in use, and the debris generated during cutting cannot be cleaned promptly and effectively. These debris will adhere to the cut carbon paper, affecting the cleanliness and quality of the carbon paper, and may further affect the subsequent assembly and use of the fuel cell.

[0004] For example, a fuel cell carbon paper cutting device disclosed in announcement number CN218905536U, when in use, the cutting device of this patent places an outer cutting frame, an inner cutting frame and a cutting knife on a cutting platform, lifts the inner cutting frame and the cutting knife, places a sheet of carbon paper or a coil of carbon paper on the outer cutting frame, lowers the inner cutting frame and the cutting knife, presses the carbon paper to be cut with the inner cutting frame, rotates the cutting knife one circle, and when cutting is completed, lifts the inner cutting frame and the cutting knife, and takes out the cut carbon paper.

[0005] The fuel cell carbon paper cutting device may generate carbon paper debris during the cutting process, but due to the lack of a cleaning mechanism, these debris cannot be cleaned promptly and effectively. These debris will adhere to the cut carbon paper, affecting the cleanliness and quality of the carbon paper, and may further affect the subsequent assembly and use of the fuel cell.

[0006] Therefore, it is necessary to invent a cutting device for fuel cell carbon paper production and processing to solve the above problems. Utility Model Content

[0012] Preferably, the saw blade of the electric circular saw is replaced with a disc blade, and a waste collection groove is provided on one side of the top of the cutting workbench close to the supporting bracket.

[0013] The disc blade is more suitable for fine cutting and improves the cutting quality; the waste collection trough is used to collect the cut scraps.

[0014] Preferably, a limiting slide is installed on the top of the load-bearing bracket, and a roller is installed on the bottom of the loading plate, and the roller is slidably connected to the limiting slide.

[0015] The sliding connection between the limiting slide and the roller provides a guide for the movement of the loading plate, further ensuring the accuracy and stability of cutting.

[0016] Preferably, a limiting pressure plate is provided below the bearing bracket, and a rubber anti-slip pad is fixedly connected to the bottom of the limiting pressure plate.

When cutting fuel cell carbon paper, the dust collector quickly sucks away the generated dust and debris through the suction pipe and nozzle, effectively keeping the cutting area clean. This not only avoids dust pollution on the surface of the carbon paper and ensures the processing quality of the carbon paper, but also improves the operating environment and reduces the health impact of dust on operators.

[0026] 2. The combination of the limit pressure plate and the rubber anti-skid pad can be used to accurately press the fuel cell carbon paper through the drive of the No. 2 electric push rod to ensure that the carbon paper will not deviate or move during the cutting process. At the same time, the design of the limit slide and roller ensures that the carrier plate can slide smoothly and accurately along the predetermined track under the drive of the ball screw, thereby driving the electric circular saw to perform precise cutting, effectively reducing the deviation and error in the cutting process, and improving the cutting quality and production efficiency of the carbon paper.
