[0002] During the production process of lithium batteries, it is necessary to apply blue films (insulating films) to the lithium batteries so that the lithium batteries can effectively protect the battery cores during subsequent circulation. When applying the blue films, U-shaped coating is usually carried out first, that is, three sides of the battery are coated first, and the blue films extending a certain length on both sides are used to coat the two sides of the battery. Before coating the sides, it is necessary to perform a two-character cutting operation on the extended blue films to facilitate folding and coating. The existing two-character cutting devices need to clamp the blue films first and then perform cutting operations through the scissor assemblies, which takes a long time and requires a large device space.

Specifically, the feeding limit buffer member 350 has an elastic buffer head, and the feeding slider 330 moves to contact the elastic buffer head to limit the further movement of the feeding slider 330.
[0036] Please refer to Figures 3 to 6 , in this embodiment, the clamping device 200 includes an upper clamping member 210 and a lower clamping member 220 movably arranged on the mounting base 100. The upper clamping member 210 and the lower clamping member 220 approach or move away from each other along the z-axis direction to clamp or release the blue film to be sheared. Specifically, the z-axis direction is the vertical direction, the bottom blue film is placed horizontally, and the upper clamping member 210 and the lower clamping member 220 move vertically to clamp the blue film.

Specifically, the upper clamping driving member 212 can be, for example, a driving cylinder.
[0039] Furthermore, the upper clamping member 210 further includes a clamping limit buffer member 213. The clamping limit buffer member 213 is installed on the mounting base 100 to limit the stroke of the upper clamping plate 211. Specifically, the clamping limit buffer member 213 has an elastic buffer head, and when the upper clamping slider 120 moves to contact the elastic buffer head, the movement of the upper clamping slider 120 is restricted.
[0040] In one embodiment, the lower clamping member 220 includes a lower clamping plate 221, a lower clamping driving member 222, a lower mounting plate 223, a telescopic assembly 230, and a cutter assembly 240. The cutter assembly 240 is fixedly arranged on the lower mounting plate 223, and the lower clamping plate 221 is telescopically connected to the lower mounting plate 223 through the telescopic assembly 230. The lower clamping driving member 222 is fixedly connected to the mounting base 100, and the output end of the lower clamping driving member 222 is connected to the lower mounting plate 223 to drive the lower clamping plate 221 to approach or move away from the upper clamping plate 211, and drive the cutter assembly 240 to move relative to the lower clamping plate 221 towards the blue film to perform a two-word shearing operation on the blue film. Specifically, the lower clamping driving member 222 can be, for example, a driving cylinder. Both the lower mounting plate 223 and the output end of the lower clamping driving member 222 are fixedly connected to the lower clamping slider 130 to ensure that the lower mounting plate 223 moves along the z-axis.
[0041] Further, the telescopic assembly 230 includes a guide rod 231 and a spring 232 sleeved on the guide rod 231. The lower mounting plate 223 is provided with a guide hole. One end of the guide rod 231 passes through the guide hole and is fixed to the lower clamping plate 221. Two ends of the spring 232 respectively abut against the lower clamping plate 221 and the lower mounting plate 223. The lower mounting plate 223 can move along the guide rod 231 under the drive of the lower clamping drive member 222. Further, a limit block 233 for restricting the guide rod 231 from disengaging from the guide hole is provided at the end of the guide rod 231.
[0042] In one embodiment, the cutter assembly 240 includes a left cutter member 241 and a right cutter member 242 arranged at intervals in the y-axis direction. Both the left cutter member 241 and the right cutter member 242 include a cutter seat 243 and a blade 244. The cutter assembly 240 is installed below the lower clamping plate 221. Cutting grooves 201 are provided at positions corresponding to the blades 244 on both the lower clamping plate 221 and the upper clamping plate 211. When the lower mounting plate 223 moves, it drives the blade 244 to move along the z-axis through the cutting groove 201 of the lower clamping plate 221 to cut the blue film. By providing the cutting groove 201 on the upper clamping plate 211 as well, it can provide space for the blade 244 to continue moving upward and avoid the blade 244 hitting the upper clamping plate 211 and causing blade damage.
[0043] Further, the cutting edge of the blade 244 at the end far from the mounting seat 100 is higher than the other end. Through this setting, the blade 244 can form a point contact with the blue film, which is more convenient for cutting the blue film.
[0044] Further, the cutter seat 243 includes a first cutter seat 245 and a second cutter seat 246 that are detachably connected. The first cutter seat 245 is fixed to the lower mounting plate 223, and the blade 244 is clamped between the first cutter seat 245 and the second cutter seat 246. Specifically, the first cutter seat 245 and the second cutter seat 246 can be detachably connected by means of bolts, so as to facilitate the replacement of the blade 244 and make equipment maintenance more convenient.
[0045] Further, one of the upper clamping drive member 212 and the lower clamping drive member 222 is fixed on one side of the mounting seat 100 close to the clamping slide rail 110, and the other is fixed on the side of the mounting seat 100 away from the clamping slide rail 110.

[0046] The movement process of the vertical two-character cutting mechanism of the lithium battery in the embodiment of the present utility model is as follows:
[0047] The feeding drive member 320 drives the mounting base 100 to move along the x-axis to the two-character cutting station of the battery. At this station, the upper clamping drive member 212 drives the upper clamping plate 211 to move downward, and the lower clamping drive member 222 drives the lower mounting plate 223 to move upward, driving the lower clamping plate 221 to move upward to cooperate with the upper clamping plate 211 to clamp the blue film. After the blue film is clamped, the lower clamping drive member 222 drives the lower mounting plate 223 to continue moving upward. At this time, the spring is compressed, and the blade 244 continues to move upward until the blue film is cut. After the cutting is completed, the blade 244 retracts, and the lower clamping plate 221 descends to the initial position.
[0048] The embodiment of the present utility model further provides a blue film device (not shown in the figure), which includes the above-mentioned vertical two-character cutting mechanism of the lithium battery. Further, the blue film device includes at least two of the above-mentioned vertical two-character cutting mechanisms of the lithium battery. Specifically, the two two-character cutting mechanisms are respectively arranged on the left and right sides of the blue film to be cut, and the two-character cutting operation is performed on both sides of the blue film at the same time, which is beneficial to improving the blue film efficiency of the battery.
