[0022] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In order to solve the technical problem that in the prior art, the film wrapping machine only wraps the peripheral side of the battery module, and if the top of the battery module is not wrapped, the dust prevention effect of the battery module is poor, the present utility model provides a film wrapping and packing mechanism for a battery module, which can cover a film layer on the top of the battery module.

[0024] Please refer to Figures 1-5 , in an embodiment of the present utility model, a film wrapping and packing mechanism for a battery module includes a mounting frame 1 and a film wrapping member 2. The film wrapping member 2 is connected to the mounting frame 1. The film wrapping member 2 can be used to wind the winding film around the peripheral side of the battery module. It further includes a film feeding unit 3 and a transmission unit 4. The film feeding unit 3 is arranged on one side inside the mounting frame 1. A film roll is rotatably arranged inside the film feeding unit 3. The film feeding unit 3 can clamp or release one end of the film, and the film feeding unit 3 can also cut the film. The transmission unit 4 is movably connected to the mounting frame 1. The transmission unit 4 can also clamp or release one end of the film. When the transmission unit 4 clamps one end of the film and the film feeding unit 3 releases one end of the film, the transmission unit 4 can drive the film roll to rotate and unwind the film, and convey the film with a preset length after cutting to the top of the battery module.

[0025] In this specific embodiment, when the battery module is placed inside the mounting frame 1, the film wrapping member 2 rotates around the battery module, and then the winding film can be wound around the peripheral side of the battery module. It should be noted that the length of the film after cutting is greater than the length of the battery module. That is, when the film after cutting is placed on the top of the battery module, the opposite sides of the film after cutting will droop to the opposite sides of the battery module. When the winding film is wound around the peripheral side of the battery module, the film on the top can be fixed at the same time.

[0026] It should be noted that the film feeding unit 3 is not limited to a certain specific structure, as long as it can clamp or release one end of the film and can cut the film, and no other limitations are made here.

[0027] In one embodiment, the film feeding unit 3 includes a base 31, a film unwinding roller 32, a first clamping member 33 and a cutting member 34. The film unwinding roller 32 is rotatably arranged inside the base 31. The film roll is fixedly sleeved on the film unwinding roller 32. The first clamping member 33 is arranged inside the base 31 and above the film unwinding roller 32. The first clamping member 33 can clamp or release one end of the film. The cutting member 34 is arranged on one side of the base 31 and above the first clamping member 33. The cutting member 34 can cut the film.

[0028] In addition, two guiding rollers 35 are rotatably arranged between the film unwinding roller 32 and the first clamping member 33 inside the base 31. A guiding gap is formed between the two guiding rollers 35. The film passes through the guiding gap.

[0029] In one embodiment, the transmission unit 4 includes a conveyor 41 and a second clamping member 42. The conveyor 41 is movably connected to the mounting bracket 1, and the second clamping member 42 is movably connected to the conveyor 41.

[0030] It should be noted that when the second clamping member 42 clamps one end of the film and the first clamping member 33 releases one end of the film, by driving the second clamping member 42 to move in the vertical direction through the conveyor 41, the film roll can be driven to rotate and unwind the film. When the film of a preset length is unwound, the first clamping member 33 fixes the film again, and the cut-off member 34 cuts off the unwound film.

[0031] In this specific embodiment, the first clamping member 33 includes a first clamping plate 331, a first pressing plate 332, and two first telescopic portions 333. The first clamping plate 331 is fixedly arranged in the base 31. The two first telescopic portions 333 are respectively fixedly arranged on the opposite sides of the first clamping plate 331, and the movable ends of the two first telescopic portions 333 are fixedly connected to the first pressing plate 332. A pressing gap for the film to pass through is formed between the first clamping plate 331 and the first pressing plate 332, and a plurality of grooves 330 are correspondingly formed on the first clamping plate 331 and the first pressing plate 332; the second clamping member 42 includes a second clamping plate 421, a second pressing plate 422, and two second telescopic portions 423.

The two second telescopic portions 423 are respectively fixedly arranged on the opposite sides of the second clamping plate 421, and the movable ends of the two second telescopic portions 423 are both fixed to the second pressing plate 422. A pressing space for the film to pass through is formed between the second clamping plate 421 and the second pressing plate 422. A plurality of protrusions 420 are correspondingly arranged on the second clamping plate 421 and the second pressing plate 422, and each of the protrusions 420 can correspondingly extend into each of the grooves 330.

[0032] Specifically, when the first clamping plate 331 and the first pressing plate 332 clamp and fix the film, the two protrusions 420 can extend into the grooves 330 to also fix one end of the film.

[0033] It should be noted that the number of the grooves 330 and the protrusions 420 is 2 - 6. In this specific embodiment, the number of the grooves 330 on the first clamping plate 331 and the first pressing plate is 5, and the number of the protrusions 420 on the second clamping plate 421 and the second pressing plate 422 is also 5.
