[0024] refer to Figure 1 and Figure 2 The clamping assembly 11 includes a servo motor 111, which is fixedly installed on both sides of the top of the profile frame 7. The output end of the servo motor 111 is fixedly connected to a bidirectional screw 112, the bottom of the bidirectional screw 112 penetrates the inner wall of the profile frame 7, and both sides of the surface of the bidirectional screw 112 are threadedly connected to a clamping frame 113.

[0025] As a technical optimization scheme of the utility model, by setting up the clamping assembly 11, the servo motor 111 can effectively drive the bidirectional screw 112 to rotate, and the bidirectional screw 112 drives the clamping frame 113 to move inward, so that the clamping frame 113 can position the insulating film, thereby improving the stability of the insulating film during cutting and preventing the shaking of the insulating film from affecting its cutting accuracy.

The inner wall of the screw hole 121 is threadedly connected with a bolt 122, and the left side of the bolt 122 penetrates to the left side of the mounting plate 9.

[0027] As a technical optimization solution of the utility model, by providing a replacement component 12, the bolt 122 can be effectively screwed into the inside of the screw hole 121, so that the blade 10 can be fixed. When the blade 10 is damaged and needs to be replaced, the user can remove it from the inside of the screw hole 121 by twisting the bolt 122, thereby facilitating the user to replace the blade 10.

[0036] The working principle and use process of the utility model are as follows: when in use, the battery is first fixed by the film coating device 4, and then the insulating film on the surface of the unwinding frame 2 is coated on the battery. When the battery is coated, the user starts the servo motor 111 to drive the bidirectional screw 112 to rotate, and the bidirectional screw 112 drives the clamping frame 113 to move inward, so that the clamping frame 113 can position the insulating film, thereby improving the stability of the insulating film when cutting, avoiding the shaking of the insulating film to affect the accuracy of its cutting, and fixing the anti-slip strip 14 through the inner wall of the groove 13, and the anti-slip strip 14 is fixed through the inner wall of the groove 13. 14 can increase the friction between the clamping frame 113 and the insulating film, thereby improving the stability of the insulating film clamping. Then the user starts the electric telescopic rod 8 through the control box 15 to drive the mounting plate 9 to move. The insulating film can be cut by the blade 10 inside the mounting plate 9, thereby improving the accuracy of the insulating film cutting and the working efficiency of the battery package. When the blade 10 needs to be replaced after long-term use, the user can remove the blade 10 from the inside of the screw hole 121 by screwing the bolt 122, thereby completing the disassembly of the blade 10, thereby facilitating the user to replace the blade 10.

[0037] To sum up: this kind of battery production coating device, by setting an electric telescopic rod 8, a mounting plate 9 and a blade 10, can effectively enable the electric telescopic rod 8 to drive the blade 10 on the inner wall of the mounting plate 9 to move upward, so that the blade 10 can accurately cut the insulating film, which solves the problem that although the coating quality of the lithium battery can be improved, the coating device is not provided with a cutting structure. When the surface coating of the lithium battery is completed, the user can only manually cut the insulating film, thereby reducing the coating efficiency of the lithium battery. In addition, manual cutting is not accurate enough, which affects the reuse of the insulating film.
