As shown in fig. 1-2, the battery coating apparatus according to some embodiments of the present application includes a pressing assembly 100, a pushing assembly 200, and a stopper 300, wherein a pressing channel 110 is formed in the pressing assembly 100, the pushing assembly 200 is disposed at one side of the pressing channel 110 along a first direction X for pushing the battery 400 and the adhesive film 500 into the pressing channel 110 along the first direction X to press the adhesive film 500 to the surface of the battery 400 through the pressing assembly 100, and the stopper 300 is disposed at the other side of the pressing channel 110 along the first direction X, and the stopper 300 is movable to approach or separate from the pressing channel 110 along a direction perpendicular to the first direction X to limit the battery 400 in the pressing channel 110.

In the embodiment of the application, by arranging the compression assembly 100 and the pushing assembly 200, the compression assembly 100 is provided with the compression channel 110, and the pushing assembly 200 can be used for pushing the battery 400 and the adhesive film 500 which need to be coated into the compression channel 110 in the compression assembly 100, so that the adhesive film 500 is pressed onto the surface of the battery 400 by using the compression assembly 100, meanwhile, the limiting piece 300 is arranged on one side of the compression channel 110 far away from the pushing assembly 200, after the pushing assembly 200 pushes the battery 400 into the compression channel 110, the limiting piece 300 can be moved to be close to the compression channel 110, and the limiting piece 300 is used for limiting and fixing the battery 400 in the compression channel 110, so that the coating operation of the battery 400 is performed, and therefore, the phenomenon that the battery 400 shakes or shifts in the coating process is effectively reduced, and the coating quality is improved.

As shown in fig. 1 and 3, the first direction X refers to a movement direction in which the pushing assembly 200 pushes the battery 400 into the pressing channel 110, and the battery 400 includes a first side 410 and a second side 420 disposed opposite to each other along the first direction X, and a third side 430 and a fourth side 440 disposed opposite to each other along a direction perpendicular to the first direction X.

Specifically, as shown in fig. 2, a compressing channel 110 is formed in the compressing assembly 100, and the pushing assembly 200 pushes the battery 400 together with the adhesive film 500 into the compressing channel 110. During the process of pushing the battery 400 into the pressing channel 110, the adhesive film 500 may be pressed onto the third side 430 and the fourth side 440 of the battery 400 by the pressing assembly 100, and at the same time, the stopper 300 is moved in a direction perpendicular to the first direction X to approach the pressing channel 110, and the stopper 300 is moved to a side of the pressing channel 110 facing away from the pushing assembly 200. Thus, when the battery 400 is pushed into the pressing channel 110 by the pushing assembly 200, the battery 400 is pressed and fixed by the pressing assembly 100 along the direction perpendicular to the first direction X, and meanwhile, the limiting piece 300 contacts with the second side 420 of the battery 400 to limit the battery 400 along the first direction X, so that the battery 400 is limited and fixed in the pressing channel 110, and other sides of the battery 400 can be conveniently coated and the like.

In the embodiment of the present application, the installation base 600 provides a stable working platform for the compression assembly 100, so as to improve the stability of the compression assembly 100 during operation. The pressing members 120 are connected to the mounting base 600, the pressing members 120 are arranged at intervals along the direction perpendicular to the first direction X, a pressing channel 110 is formed between the two pressing members 120, the pressing channel 110 can accommodate the battery 400 and the adhesive film 500, and in the process that the battery 400 and the adhesive film 500 enter the pressing channel 110, the pressing members 120 are arranged oppositely can apply pressure to the battery 400 along the direction perpendicular to the first direction X, so that the adhesive film 500 can be better pressed onto the third side 430 and the fourth side 440 of the battery, meanwhile, the battery 400 can be effectively fixed along the direction perpendicular to the first direction X through the cooperation of the two pressing members 120, so that shaking of the battery 400 along the direction perpendicular to the first direction X in the pressing process is effectively reduced, and the coating quality of the battery 400 is improved.

The preset height of the pressing channel 110 along the direction perpendicular to the first direction X may be determined according to the length of the battery 400 along the direction perpendicular to the first direction X, so that the battery 400 can pass through the pressing channel 110, and at the same time, the pressing member 120 can also perform a pressing and fixing function on the battery 400.

Alternatively, as shown in fig. 1, the pressing member 120 includes a plurality of rollers 121, and the rollers 121 are arranged at intervals in a row along the first direction X, and the rollers 121 are rotatably connected to the mounting base 600.
