Description

Technical Field

[0001] The utility model relates to the technical field of aluminum foil winding, and more specifically, to a lithium battery aluminum foil winding device. Background Art

[0002] In the process of producing and processing lithium batteries, aluminum foil is an indispensable raw material. Aluminum foil plays a vital role in the process of charging and discharging lithium batteries. Aluminum foil can act as a positive electrode current collector in lithium batteries, and the current collector plays the role of carrying active substances. In the process of processing aluminum foil, it is usually necessary to roll up the produced aluminum foil and then transport it to the lithium battery production line for use.

[0003] During the production process, dust and impurities may adhere to the surface of aluminum foil. If they are not cleaned, the quality of the aluminum foil will be affected. In traditional aluminum foil winding devices, there is either a lack of cleaning structure for the aluminum foil or a single cleaning method with limited cleaning effect. Dust, impurities and water stains on the surface of the aluminum foil cannot be effectively removed, resulting in the aluminum foil's cleanliness and flatness failing to meet the requirements, which in turn affects the performance and quality of the battery. In response to the above problems, this device was invented. Utility Model Content

[0026] See attached Figure 1 and Figure 3 The primary cleaning mechanism 3 includes two No. 1 receiving plates 301 arranged in parallel, a cleaning brush 302 is fixedly installed on the inner wall surface of one side of the No. 1 receiving plate 301, a dust suction pipe 303 is fixedly installed on the other side of the No. 1 receiving plate 301, the dust suction pipe 303 is connected to the external fan, and a dust suction hood 304 is fixedly installed on the inner end of the dust suction pipe 303.

[0027] The aluminum foil first passes through the cleaning brush 302, and the cleaning brushes 302 on the upper and lower sides perform dust removal operations on the upper and lower surfaces of the aluminum foil. After the dust removal operation, the aluminum foil moves between the dust hoods 304 on both sides. Under the action of the fan, the dust swept off by the cleaning brush 302 is sucked into the dust hood 304 and discharged along the dust collection pipe 303.
