Description

Technical Field

[0001] The utility model relates to the technical field of battery processing, in particular to a battery core coating device. Background Art

[0002] The battery cell is the charging and discharging component inside the lithium battery. The battery cell is also divided into aluminum shell battery cell and soft pack battery cell. Therefore, when producing and processing lithium battery cells, a lithium battery cell coating device is required to coat the lithium battery cells.

[0003] In the prior art, an authorized patent with announcement number CN220358154U discloses a lithium battery cell coating device. The technical problem to be solved is to provide a lithium battery cell coating device. The scheme adopted is: a slide is provided at the top of the base, a rack is provided in the middle of the side end of the slide, the other side end of the slide is bolted to a laser rangefinder, the side end of the rack is meshed and connected to the first shift plate, the side end of the first shift plate is bolted to a connecting plate, the connecting plate is bolted to an electric push rod, the output end of the electric push rod is connected to the second shift plate, and the side end of the base is bolted to a winding device. The utility model moves the lithium battery cell by the slide and the first shift plate. During the movement of the lithium battery cell, the staff can also use a ruler and a laser rangefinder to timely detect the movement data of the lithium battery cell, thereby ensuring that the first shift plate and the lithium battery cell can be moved to a suitable position and coated.

[0004] However, the above technical solution still has the following shortcomings when it is actually used: the above device can only coat one side wall of the battery cell, while the coating of the battery cell usually requires coating on all four side walls. This requires that when coating the battery cell, the battery cell needs to be turned over and placed on the second transfer plate, which makes the battery cell coating operation cumbersome and the coating processing efficiency low. In this regard, we propose a battery cell coating device. Utility Model Content
