Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] See also Figure 1As shown, the present invention is a device for removing the plastic shell film of a battery, comprising a workbench 1, which is rotatably connected to a rotating disk 101, and is connected to a film stripping mechanism 2 and a fixing mechanism 7. The rotating disk 101 is driven to rotate by a motor, and the upper surface of the rotating disk 101 is not higher than the upper surface of the workbench 1, so that the battery can slide from the surface of the workbench 1 to the rotating disk 101.

[0037] like Figure 2 and 3 As shown, the film stripping mechanism 2 includes a mounting bracket 201, which is slidably connected to a mounting seat 202 through a guide rail slider assembly, and is connected to a linear drive assembly for driving the mounting seat 202 to slide in a horizontal direction. The mounting bracket 201 is fixedly connected to a rack 203 arranged parallel to the sliding direction of the mounting seat 202, and the length of the rack 203 is smaller than the moving stroke of the mounting seat 202.

[0038] Specifically, the driving assembly includes a screw rod 204 rotatably connected to the mounting bracket 201 and a servo motor 205 transmission-connected to the screw rod 204 . The mounting seat 202 is fixedly connected to a nut that cooperates with the screw rod 204 . The screw rod 204 is driven to rotate by the servo motor 205 , thereby realizing the movement of the mounting seat 202 .

[0039] The mounting seat 202 is rotatably connected to a vertically arranged blocking roller 3, a film stripping roller 4, a transmission shaft 5 and a rotating rod 401 through a bearing seat, and is also connected to a driving device 402 for driving the rotating rod 401 to rotate. The driving device 402 is a cylinder, which is rotatably connected to the mounting seat 202 through a cylinder seat. A strip plate 405 is hinged at the end of the cylinder, and one end of the strip plate 405 is fixedly connected to the rotating rod 401. The strip plate 405 is used to drive the rotating rod 401 to rotate through the extension and retraction of the cylinder.

[0040] And, if Figure 8 As shown, the rotating rod 401 is connected to the clamping plate 403 corresponding to the film stripping roller 4 by screws, and is located on one side of the moving direction of the film stripping roller 4 during film stripping. One side of the clamping plate 403 has a blade portion with a gradually decreasing thickness and is close to the battery 9 and the film stripping roller 4.

[0041] The blocking roller 3 and the film stripping roller 4 are arranged side by side and are used to block and limit the position of the battery 9. The transmission shaft 5 is fixedly connected with a driving wheel 501 and a walking wheel 502 meshing with the rack 203. The rotating shaft of the film stripping roller 4 is fixedly connected with a driven wheel 404 that is transmission-connected to the driving wheel 501. The driving wheel 501 and the driven wheel 404 can both be synchronous pulleys, which are transmitted to each other through a synchronous belt.

[0042] The fixing mechanism 7 includes a fixing bracket 701, which can be directly installed on the workbench 1. The fixing bracket 701 is fixedly connected to a vertically arranged telescopic device 702. The telescopic device 702 can also be a cylinder or an electric push rod. The telescopic end of the telescopic device 702 is rotatably connected to a pressure plate 703 which is concentrically arranged with the rotating disk 101, and is used to press down the battery located on the rotating disk 101 through the pressure plate 703, and drive the battery to rotate through the rotating disk 101.

[0043] like Figures 4 to 6 As shown, the mounting seat 202 is moved to the position corresponding to the rotating disk 101, and the battery 9 wrapped with the film is placed on the rotating disk 101, and one side of the film joint of the battery 9 is closely attached to the blocking roller 3 and the film stripping roller 4, so as to locate the position of the battery 9. Then, the pressing plate 703 is pressed on the battery 9 by the telescopic device 702, so that the battery 9 is fixed.

[0044] like Figure 7 and 8 As shown, at this time, the mounting base 202 is driven to move, and the traveling wheel 502 is used to roll along the rack 203 during the movement of the mounting base 202, so that the transmission shaft 5 is transmitted through the driving wheel 501 and the driven wheel 404, thereby driving the film stripping roller 4 to rotate, and the linear velocity direction of the contact point between the film stripping roller 4 and the battery 9 is parallel to the moving direction of the mounting base 202, so that the film can be gradually peeled off the outer wall of the battery 9 after being peeled off. As shown in the figure, the film stripping roller 4 rotates clockwise, and then the film is peeled off the outer wall of the battery through the rotation of the film stripping roller 4.

[0045] Furthermore, the transmission ratio between the driving wheel 501 and the driven wheel 404 is less than 1, and the film stripping roller 4 can achieve a higher rotation speed, which is beneficial to improving the film stripping effect.

[0046] The film stripping roller 4 is a rubber roller, and the circumferential surface is a serrated structure, which makes it easier to scrape off the film on the outer wall of the battery 9. After the film on the outer wall of the battery 9 is scraped off, it is brought between the clamping plate 403 and the film stripping roller 4 by the film stripping roller 4. At this time, the clamping plate 403 cooperates with the film stripping roller 4 to clamp and fix the film by rotating the rotating rod 401, and the film is taken away from the battery 9 as the mounting seat 202 moves.

[0047] like Figure 7 As shown, at the same time, when the mounting seat 202 moves away from the film, the rotating disk 101 drives the battery 9 to rotate clockwise, producing an effect of tearing the film off the surface of the battery 9, thereby completely peeling off the film on the surface of the battery 9, realizing automatic film tearing, effectively reducing the manual operation process, and greatly improving the overall production efficiency.

[0048] As a further optimization scheme, it also includes a conveyor line 8 for conveying batteries through the conveyor line 8; a pushing assembly 801 is fixedly connected to the side of the conveyor line 8, such as by using a cylinder, for pushing the batteries on the conveyor line 8 to the rotating disk 101, thereby realizing automatic loading.

[0049] At the same time, a telescopic cylinder 104 is connected to the workbench 1 or the mounting bracket 201, and a push plate 105 is fixedly connected to the telescopic end of the telescopic cylinder 104, which is used to push the battery on the rotating disk 101 to the conveyor line 8, so that the battery with the film removed is pushed back to the conveyor line 8 through the telescopic cylinder 104, and then the conveyor line 8 moves the position to move the next battery to be removed from the film to the position of the pushing assembly 801, thereby realizing the effect of automatic loading and unloading, further improving the degree of automation, and further improving production efficiency.

[0050] Embodiment 2

[0051] like Figure 1 , 9 As shown in FIG. 10 , based on the first embodiment, a collecting box 102 is provided on one side of the workbench 1, and the upper opening of the collecting box 102 is rotatably connected to two pairs of rollers 103 arranged side by side; the two pairs of rollers 103 are in contact with each other and rotate in opposite directions.

[0052] When the clamping plate 403 cooperates with the film stripping roller 4 to clamp and fix the film, and moves with the mounting base 202, the film is taken away from the battery 9 position, and the two pairs of rollers 103 rotate, and as shown in the direction of the arrow in the figure, one pair of rollers 103 rotates counterclockwise and the other pair of rollers 103 rotates clockwise. When the mounting base 202 moves to just above the collection box 102, the rotating rod 401 rotates in the opposite direction, driving the clamping plate 403 to rotate in the direction away from the film stripping roller 4, thereby loosening the clamped film. When the downwardly drooping film touches the pair of rollers 103, the film taken away from the battery is pulled into the collection box 102 under the rotation of the pair of rollers 103, thereby realizing automatic collection of the film, further reducing the process of manually removing the film from the film stripping roller 4, realizing the automation of removing the battery plastic shell coating, and greatly improving the overall production efficiency.
