Description

Technical Field

[0001] The present disclosure relates to the technical field of electrode production-related equipment, and in particular to an electrode dust removal device and electrode production equipment. Background Art

[0002] During the electrode production process, dust will be generated in each process link such as coating, rolling, slitting, die-cutting, winding, lamination, etc., which will have a negative impact on the performance of the finished battery cells. Larger particles may even pierce the diaphragm, causing the positive and negative electrodes to contact and cause a short circuit, which seriously threatens the safety of use.

[0003] Existing technologies such as patent CN220311080U disclose a lithium battery pole piece dust removal and cleaning device, which performs dust removal operations on the pole pieces through two oppositely arranged brush rollers. The brush rollers are arranged in a dust removal hood, and the two dust removal hoods are arranged oppositely to form a pole piece dust removal channel. The dust removal hood is also provided with a pipe interface connected to a dust removal fan, so that the dust removal fan can suck away the dust, thereby effectively preventing the dust in the pole piece channel from causing secondary pollution to the pole piece. Moreover, the dust removal fan can also form a negative pressure environment in the pole piece dust removal channel to avoid dust falling out of the pole piece dust removal channel from the entrance of the pole piece dust removal channel, thereby effectively preventing the dust from causing secondary pollution to the pole piece at the entrance of the pole piece dust removal channel. At the same time, the two brush rollers are driven to move closer to or away from each other by the first driving cylinder and the second driving cylinder to adjust the pressure between the two brush rollers.

[0004] However, the distance between the two dust removal covers of the above-mentioned pole piece dust removal and cleaning device is too large, so that the area of the entrance and exit of the pole piece dust removal channel is larger, resulting in a low dust removal vacuum degree in the pole piece dust removal channel, which greatly increases the possibility of dust escaping from the entrance of the pole piece dust removal channel, thereby greatly reducing the dust removal effect of the above-mentioned pole piece dust removal and cleaning device on the pole piece.
