Description

Technical Field

[0001] The utility model relates to the technical field of bipolar plate processing, in particular to a dust removal device for welding bipolar plates. Background Art

[0002] Bipolar plates, also known as current collector plates, are one of the important components of fuel cells. The function of bipolar plates is to provide gas flow channels to prevent hydrogen and oxygen in the battery gas chamber from communicating with each other and to establish a current path between the positive and negative electrodes in series. During the welding process of bipolar plates, a large amount of dust will adhere to the outer surface of the bipolar plates, so it is necessary to first use a dust removal device to remove dust from the outside of the bipolar plates, thereby improving the safety and stability of subsequent processing of the bipolar plates.

[0003] A dust removal device for welding bipolar plates disclosed in the Chinese utility model patent application disclosure CN208662886U is connected to a motor and an air suction pump, so that the dust removal nozzle can remove dust around the storage table, ensuring the dust removal effect of the dust removal device in all directions without dead ends, and the exhaust hood provided can remove the smoke during the welding process, thereby improving the effect of removing welding smoke and ensuring the cleanliness of the welding environment. However, the overall position of the dust removal device is fixed, resulting in poor flexibility when dusting bipolar plates of different specifications, which may cause some positions of the bipolar plates to be unable to be effectively dusted and cleaned, thereby affecting the overall working effect of the dust removal device.
