The working principle of the battery coating device in this embodiment is described below, and the working principle can be divided into three working stages, specifically as follows:

a first working phase: referring to fig. 5 and 6, it is necessary to place the battery 1 directly under the press block 410 before the coating, and fix the flexible film 2 to the upper surface of the battery 1. Then, the second lifting seat 420 is driven by the third driving mechanism 440 to vertically move downwards, and the pressing block 410 presses the upper surfaces of the flexible film 2 and the battery 1, so that the positioning of the flexible film 2 is realized.

And a second working stage: referring to fig. 7 and 8, the first lifting seat 210 drives the wrapping member 220 and the side pressing member 310 to move downward under the action of the first driving mechanism 240. In this process, the two wrapping members 220 are relatively far away, and the wrapping members 220 contact the flexible films 2 protruding from the left and right sides at first, so that the wrapping film blocks 223 press and bend the flexible films 2, thereby realizing the wrapping of the two side walls of the battery 1. When the first lifting seat 210 continues to move downwards, the wrapping member 220 moves to the lower side of the battery 1, and the side pressure portion 311 can press the flexible film 2 on both sides of the battery 1, so as to maintain the bent shape of the flexible film 2. Under the action of the horizontal pushing force of the second elastic piece 330, the side pressing piece 310 is always tightly attached to the battery 1, so that the soft film 2 is kept flat and not deflected.

And a third working stage: referring to fig. 9 and 10, when the upper surface of the film wrapping block 223 just descends to the same height as the lower surface of the battery 1, the wrapping members 220 approach each other in the left-right direction Y by the driving of the second driving mechanism 250, so that the film wrapping block 223 folds the left and right excessive flexible films 2 to the lower surface of the battery 1, thereby completing the film wrapping process once. In the above process, the film wrapping block 223 can be always attached to the lower surface of the battery 1 due to the upward thrust of the first elastic member 230, so as to ensure the flatness of the film.

In summary, the battery coating device provided in this embodiment realizes high automation of battery coating by matching the coating mechanism 200, the side pressing mechanism 300 and the material pressing mechanism 400 with the coating, and in addition, the device is further provided with the coating block 223 and the side pressing portion 311 with chamfer angles, which reduces the generation of wrinkles and bubbles when bending the soft film 2, and improves the coating quality while promoting the coating efficiency.
