Description

Technical Field

[0001] The utility model relates to the technical field of battery shell coating processing, in particular to a multi-station coating device for a battery shell. Background Art

[0002] During the battery production process, the battery casing is often worn, scratched, and corroded. In order to prevent accidental contact between the positive and negative poles of the battery, a protective film is coated on the battery casing.

[0003] A Chinese patent discloses a multi-station lithium battery film coating and packaging device, with the publication number CN216035305U, comprising a film coating and packaging equipment body, on which a driving platform and a film coating platform are provided, a power motor is fixedly installed on the top side of the driving platform, and a rotating shaft is fixedly installed on the output shaft of the power motor through a coupling, and a driving gear is fixedly installed on the top of the rotating shaft, and two driven gears are provided on both sides of the driving gear. In the multi-station lithium battery film coating and packaging device, the power motor runs to drive the driving gear to rotate, and can drive multiple driven gears to rotate. The lithium battery body is placed in a battery placement groove on a placement plate, and multiple placement plates are provided, so that multiple stations can film and package the lithium battery body at the same time. The simultaneous operation of multiple stations can speed up the film coating speed, and the film on the film coating roller body on the film coating platform is pulled onto the lithium battery body to perform the film coating operation.

[0004] However, it still has the following disadvantages: the device uses a power motor to drive the battery to rotate so that the packaging film is wrapped on the battery surface. However, since the packaging film has a certain elasticity, when the coating film is pulled, the film roller will vibrate up and down, so that the film body cannot be well wrapped on the outer surface of the battery. To this end, we proposed a battery shell multi-station coating device to solve this problem. Utility Model Content
