Description

Technical Field

[0001] The utility model belongs to the field of loading and unloading devices, in particular to a loading and unloading structure for sealing a bipolar plate body of a fuel cell. Background Art

[0002] The bipolar plate in a fuel cell is a key component of the battery system. It is used to stack multiple single fuel cells together. Sealing is a very important requirement in the design of fuel cell bipolar plates. The main purpose is to prevent gas leakage and ensure the efficiency and stability of the fuel cell. When using adhesives and sealants to seal the bipolar plates of fuel cells, automated glue coating equipment is often used for sealing operations.

[0003] During the automated gluing process, the colloid usually needs to be extracted from the storage container and pumped from the storage container to the gluing equipment through an automated pump, peristaltic pump or pressurizing device. Before and after the use of the automated gluing equipment, the colloid needs to be loaded and unloaded, and stored in barrels, bags or cans. Since the colloid is relatively viscous and has strong adhesion, it is easy for the colloid to remain in the storage container during the loading and unloading process. The residual colloid will solidify after standing, which will not only affect the capacity and weight of the container, but also be extremely difficult to clean, affecting the subsequent use of the container.
