[0091] The traction mechanism 23 includes a first motor 231 fixed on the frame 211, a rolling assembly a232 arranged on the guide a221 and fixedly connected to the upper end of the frame 211, and a rolling assembly a232 arranged on the guide b222 and fixedly connected to the lower end of the frame 211 The first motor 231 synchronously drives the rolling assembly a232 and the rolling assembly b233 to move along the guide a221 and the guide b222 through the belt a234 and the belt b235.
[0092] It is worth mentioning that the positioning mechanism 12 is provided at the cross-cutting mechanism 13, so that after the cross-cutting mechanism 13 cuts the film, the film can be processed through the cooperation of the upper limit roller 123, the lower limit roller 124 and the support roller 122. The limit prevents it from sagging, avoids the end of the film itself and itself sticking together to cause the film to not be used normally, and the suction member 212 of the suction mechanism 21 can pass between the upper limit roller 123 and the lower limit roller 124 , So that while achieving the effect of limiting the end of the film, without affecting the end of the film, the end of the film can be adsorbed and fixed quickly and pulled out. The structure is ingenious and the production efficiency is high.

[0098] What’s more worth mentioning is that the film pressing assembly 422 is provided on the guide assembly 421, so that when the electrode group 10 is connected to the cut film to move along the guide groove 4213, it can pass the pressing roller a4221 and the pressing roller b4222.
