Description

Technical Field

[0001] This utility model relates to the field of battery cell cleaning technology, specifically to a lithium battery cell cleaning machine. Background Technology

[0002] The battery cell is the core component of a lithium metal battery. It is divided into three types: aluminum-cased cells, pouch cells, and cylindrical cells. Before assembly, most lithium batteries require cleaning of the cell surface to ensure that no electrolyte or other foreign matter remains on the cell surface that could affect the operation of the lithium battery.

[0003] Chinese patent CN222000970U discloses a lithium battery cell cleaning machine, including a cleaning body, a scraper, a filter, a drive roller, and cleaning components. Symmetrical side plates are arranged on the upper part of the collection tank, and the scraper is positioned between the two side plates. The drive roller and the cleaning components are positioned between the side plates and close to the collection tank, with the drive roller and cleaning components arranged alternately. The filter is located below the drive roller and covers the upper opening of the collection tank. This invention cleans the bottom surface of the battery cells using the cleaning components. During use, water enters through the inlet pipe and flows through the outlet to rinse the passing cells. Simultaneously, the housing rotates, causing the brush to clean the bottom of the cells. Wastewater generated during the cleaning process flows directly into the collection tank, thus achieving cleaning of the bottom of the cells and avoiding the need for operators to flip them over for further cleaning.

[0004] However, in the above technical solution, the bottom of the battery cell is cleaned by setting a cleaning component at the bottom of the battery cell and rinsing it with a brush through a water inlet pipe. However, the brush bristles on the rotating housing have notches, which can cause cleaning dead angles when they come into contact with the bottom of the battery cell. Utility Model Content

[0023] Example 2, as Figures 2-4As shown, this utility model proposes a lithium battery cell cleaning machine. Compared with Embodiment 1, this embodiment describes the detailed structure of the cleaning component. The cleaning component also includes a drive device 6, an extension rod 7, a synchronous gear 8, a synchronous toothed belt 9, a cleaning component 10, and an auxiliary cleaning component. The number of drive devices 6 corresponds to the number of first rotating cylinders 2. The drive devices 6 are connected to the main body 1 of the cleaning machine, and the output end of the drive device 6 is connected to any end of the first rotating cylinder 2. The drive device 6 is selected from, but is not limited to, an electric motor. The number of extension rods 7 corresponds to the number of first rotating cylinders 2. The extension rods 7 are connected to the first rotating cylinders 2. One end of cylinder 2; six synchronous gears 8 are provided, four of which are arranged in parallel on the extension rod 7, and the other two are arranged on the two middle extension rods 7.

The first gear 14 on the first rotating drum 2 rotates synchronously and meshes with the second gear 15. The first rotating cylinder 2 and the second rotating cylinder 3 rotate together, which in turn drives the second rotating cylinder 3 to rotate. When the first rotating cylinder 2 and the second rotating cylinder 3 rotate, the brush 4 connected to their surfaces will also rotate synchronously. The brush 4 scrapes the lower end face of the battery cell. At the same time, the external conveying equipment delivers cleaning liquid into the connecting pipe 13. The cleaning liquid is sprayed out from the spray head 12 on the cleaning pipe 11 to clean the lower end face of the battery cell. After cleaning, the liquid will fall naturally and be collected by the main body 1 of the cleaning machine. The collection tank formed at the bottom of the main body 1 of the cleaning machine will collect it, so as to facilitate the centralized collection and processing in the later stage. The cleaned battery cell will then enter the next process.
