The following description will be made with reference to specific embodiments to describe the edge sealing method and process of the battery sheet 5 by using the automatic edge sealing apparatus:

referring to fig. 13, the battery piece 5 to be edge-sealed in the embodiment is a square shape, and includes two first side edges 5a facing each other and parallel to each other and two second side edges 5b facing each other and parallel to each other, wherein a first chamfered portion 5c and a second chamfered portion 5d are respectively formed at two ends of the first side edge 5a in the length direction, and the entire circumferential edge of the battery piece 5 needs to be edge-sealed by coating.

Referring to fig. 7 to 12, the battery piece 5 to be edge-sealed is transferred by an external carrying device, flatly placed on the slide platform 11 of the first group of slide devices 1, and fixedly adsorbed and fixed on the slide platform 11, and two first side edge portions 5a to be edge-sealed on the battery piece 5 are both located outside the slide platform 11.

The battery piece positioning system obtains the actual position of the battery piece 5 on the slide platform 11, compares the actual position with a preset value, and transmits corresponding position information to be adjusted to the platform adjusting mechanism and the driving devices 4 at two sides, wherein the platform adjusting mechanism drives the slide platform 11 to rotate, so that the extending direction of the first side edge part 5a is parallel to the X direction of the first direction; the two-sided drive devices 4 drive the respective coating device 2 to move in the second direction Y, so that the two-sided coating wheel 21 discharges at a position corresponding to the two-sided first side edge portion 5a, i.e. so that the first side edge portion 5a is located in the annular groove 213 of the coating wheel 21 in both the Y direction and the Z direction.

The slide glass device 1 is driven by the advancing device 3 to advance forwards in a forward translation mode along the first direction X, and the coating devices 2 on the two sides are kept still at the Y-direction position, so that in the process that the slide glass platform 11 translates along the first direction X, the distance between the discharging position of the coating rotating wheel 21 and the first side edge part 5a is kept to be a constant preset value or kept within a preset range. In the process that the slide glass device 1 translates along the first direction X, the two groups of coating rotating wheels 21 are respectively driven to rotate around the axis line of the two groups of coating rotating wheels, when the first side edge part 5a passes through the annular groove 213, the coating material flowing out of the discharge channel 213 into the annular groove 213 is applied to the first side edge part 5a, and simultaneously, the coating edge sealing of the first side edge parts 5a at two sides is realized. During coating, the slide platform 11 moves horizontally in the first direction X at a speed consistent with or as close as possible to the linear speed of the coating wheel 21 during the rotational discharge, specifically, at the discharge opening of the discharge channel 214 of the coating wheel 21, so that the coating material can be applied to the first side edge portion 5a as uniformly as possible.

In other embodiments, the slide glass platform 11 with the battery plate 5 adsorbed thereon may be kept stationary, and the coating device 2 is driven to move in a translational manner along the length extension direction of the side edge portion to be edge-sealed on the battery plate 5 as a whole, so that the coating wheel 21 rotates to discharge material while translating relative to the battery plate 5 to achieve coating edge-sealing on the battery plate 5. The slide platform 11 and the coating device 2 can also be driven to move in translation respectively so as to generate relative movement between the two.

In other embodiments, only one set of the slide device 1 and only one set of the coating device 2 may be provided, and the slide device 1 may coat the hem seal on only one side edge portion at a time during the translation in the first direction X. And after finishing the edge sealing of one side edge portion by coating, the slide glass device 1 is driven to return to the initial position, meanwhile, the rotating platform 11 rotates by a proper angle to enable the other side edge portion to be sealed to extend parallel to the first direction, and then the slide glass device 1 is driven to translate along the first direction X to realize the edge sealing of the other side edge portion to be sealed by coating. By circulating in this way, the edge sealing treatment of all the side edge parts is realized, and the production efficiency is correspondingly reduced compared with the mode of the embodiment of the application.
