[0024] In order to achieve vibration of the polyimide film, the rotating vibration mechanism 4 includes a rotating screw 12, a three-spoke plate 13, a distance-adjusting slider 14, a driving ring 15, a rotating ring 16, a connecting rod 17 and a rotating motor 18. The rotating screw 12 is rotatably connected to the vertical plate 11, the three-spoke plate 13 is fixedly connected to one end of the rotating screw 12, the distance-adjusting slider 14 is slidably connected to the three-spoke plate 13, the driving ring 15 is threadedly connected to the rotating screw 12, the rotating ring 16 is rotatably connected to the driving ring 15, one end of the connecting rod 17 is rotatably connected to the rotating ring 16, and the other end of the connecting rod 17 is rotatably connected to the distance-adjusting slider 14, and the rotating motor 18 is arranged on the vertical plate 11 and the output shaft passes through the vertical plate 11 and is connected to the rotating screw 12.

[0025] In order to achieve the tensioning of the polyimide film, the tensioning mechanism 5 includes a guide rod 19, a lifting slider 20, a clamping spring 21, a driving wheel 22, a cam 23 and a driving motor 24. The guide rod 19 is vertically arranged on the base plate 1 and is arranged between the vertical plate 11 and the clamping plate 6. The lifting slider 20 is slidably connected to the guide rod 19. One end of the clamping spring 21 is arranged on the base plate 1, and the other end of the clamping spring 21 is arranged at the lower end of the lifting slider 20.
