Description

Technical Field

[0001] The present invention relates to the field of automatic film wrapping equipment, and more particularly, to a large bread film wrapping device. Background Art

[0002] With the development of technology, new energy power batteries are increasingly widely used. As a core component of the battery, the production quality of the battery cell is closely related to the quality of the battery. During the production process of the battery cell, it is necessary to wrap an insulating film on the surface of the battery cell except for the top cover side, and the quality of wrapping the insulating film has an important impact on the performance and safety of the battery cell.

[0003] The existing method of wrapping the insulating film is generally to first wrap the bottom surface of the battery cell and the two relatively large side surfaces, and then fold and flatten the two sides of the insulating film so that the insulating film fits on the remaining two relatively small side surfaces of the battery cell. The bottom surface of the battery cell and the two relatively large side surfaces are the so-called large surfaces. The existing automatic film wrapping equipment has a complex process when wrapping the large surface, low film wrapping efficiency, and low film wrapping accuracy, and cannot meet the requirements for production efficiency and quality.

[0004] In view of this, it is necessary to provide a battery cell film wrapping device that can solve the above defects to quickly complete the large surface film wrapping work of the battery cell and improve production efficiency. Summary of the Invention

[0006] A large bread film wrapping device includes a pushing mechanism, a first tensioning mechanism, and a second tensioning mechanism. The first tensioning mechanism and the second tensioning mechanism are arranged opposite to each other, and the pushing mechanism is arranged between the first tensioning mechanism and the second tensioning mechanism. The pushing mechanism is used to drive the product to move in a straight line direction, and the first tensioning mechanism and the second tensioning mechanism are used to tension the insulating film on the moving route of the product.

[0012] Further, the cutting unit includes a cutter and a second driving member. The second driving member drives the cutter to slide to cut the insulating film.

[0013] Further, the first clamping unit includes a first clamping member and a third driving member. The third driving member drives the first clamping member to move and clamp the insulating film.

[0014] Further, the second tensioning mechanism includes a second driving unit, a second clamping unit, and a flattening unit.

However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0024] As Figures 1 to 5 shown, in a preferred embodiment, the large bread film device of the present invention includes a pushing mechanism 1 for driving the product to move horizontally, and a first tensioning mechanism 2 and a second tensioning mechanism 3 for vertically tensioning the insulating film. The first tensioning mechanism 2 and the second tensioning mechanism 3 are arranged opposite to each other up and down, and the pushing mechanism 1 is horizontally arranged between the first tensioning mechanism 2 and the second tensioning mechanism 3.

[0025] Please refer to Figure 1 and Figure 2, the pushing mechanism 1 includes a first driving unit 19, a transfer track 12, and a clamping unit 14. Among them, the first driving unit 19 includes two parallel first guide rails 11 and a clamping unit cylinder 17. A transfer track 12 is provided between the first guide rails 11. A plurality of rollers are arranged on the transfer track 12, and the extending direction of the transfer track 12 is parallel to the extending direction of the first guide rails 11. An avoidance notch 13 is provided on the transfer track 12 corresponding to the positions of the first tensioning mechanism 2 and the second tensioning mechanism 3. This avoidance notch 13 is used to avoid the insulating film, so that the insulating film can vertically block the advancing direction of the transfer track 12 under the cooperation of the first tensioning mechanism 2 and the second tensioning mechanism 3. Oppositely arranged clamping units 14 for clamping products are provided on the first guide rails 11. The clamping units 14 are slidably connected to the first guide rails 11, and a clamping unit cylinder 17 for driving the clamping units 14 to slide along the first guide rails 11 is provided on one side of the first guide rails 11. Specifically, the clamping unit 14 includes a slider 18, a clamping block 15, and a first driving member 16. The slider 18 is slidably arranged on the first guide rails 11. The first driving member 16 is fixedly arranged on the slider 18. The first driving member 16 is connected to the clamping block 15. The clamping block 15 can horizontally move towards the transfer track 12 under the drive of the first driving member 16, so as to clamp the product from both sides of the product. When the clamping unit 14 slides along the first guide rails 11, it can drive the product to move along the transfer track 12.

[0026] Please refer to Figure 3 , a positioning mechanism 4 is provided at one end of the pushing mechanism 1. The positioning mechanism 4 includes a positioning plate 42, a first positioning cylinder 45, a blocking unit 47, and a limiting unit 48. Among them, the blocking unit 47 includes a positioning roller 41 and a second positioning cylinder 44, and the limiting unit 48 includes a push plate 43 and a third positioning cylinder 46. The push plate 43 is arranged at the end of the transfer track 12, and the push plate 43 is connected to the third positioning cylinder 46. The positioning roller 41 and the positioning plate 42 are both arranged on the surface of the transfer track 12. The positioning plate 42 is located between the positioning roller 41 and the push plate 43. The positioning roller 41 and the positioning plate 42 are respectively connected to the second positioning cylinder 44 and the first positioning cylinder 45. The positioning roller 41 can vertically extend out of the surface of the transfer track 12 under the drive of the second positioning cylinder 44, so as to block the movement of the product. A suction cup (not shown) is provided on the surface of the positioning plate 42, which can adsorb the product to form positioning for the product. When the positioning is completed, the positioning plate 42 can vertically move downward under the drive of the first positioning cylinder 45, so as to release the product. When the product is placed on the positioning plate 42, the push plate 43 can extend to both sides of the product under the drive of the third positioning cylinder 46, so as to form a limit for the product in the horizontal direction.

[0027] Please refer to Figure 4, the first tensioning mechanism 2 includes a mounting plate 21 which is vertically arranged, and a cutting unit 27 for cutting the insulating film is provided near the lower end of the mounting plate 21. Specifically, the cutting unit 27 includes a second driving member 23 and a cutting knife 22. The second driving member 23 is arranged on the mounting plate 21, and the second driving member 23 is connected to the cutting knife 22. The cutting knife 22 can horizontally move under the drive of the second driving member 23, so as to cut the insulating film in the horizontal direction. A first clamping unit 24 for clamping the insulating film is slidably arranged on one side of the mounting plate 21. The first clamping unit 24 includes a first clamping member 241, a third driving member 242, and a fixing plate 243. The fixing plate 243 is horizontally arranged, the third driving member 242 is fixedly arranged on the fixing plate 243, the first clamping member 241 is arranged opposite to the mounting plate 21 and is connected to the third driving member 242. The third driving member 242 can drive the first clamping member 241 to horizontally move and abut against the surface of the mounting plate 21, so as to clamp the insulating film between the mounting plate 21 and the first clamping member 241. The first pressing roller unit 25 and the second pressing roller unit 26 are arranged on both sides below the mounting plate 21, and the first pressing roller unit 25 and the second pressing roller unit 26 can vertically move relative to the mounting plate 21. Among them, the first pressing roller unit 25 includes a fifth driving member 251 and a plurality of first pressing rollers 252 arranged in parallel. The fifth driving member 251 can drive the first pressing rollers 252 to vertically move, so as to press the product from top to bottom and form a limit on the moving product. The second pressing roller unit 26 includes a sixth driving member 261, a horizontal driving cylinder 263, and a second pressing roller 262. The sixth driving member 261 is fixedly arranged on the mounting plate 21. The sixth driving member 261 can drive the second pressing roller 262 to press the upper surface of the product from top to bottom, so that the insulating film closely adheres to the upper and lower surfaces of the product. The horizontal driving cylinder 263 is connected to the second pressing roller 262 and is used to drive the second pressing roller 262 to horizontally move, so as to flatten the insulating film.

[0028] Please refer to Figure 5, the second tensioning mechanism 3 includes a vertically arranged second driving unit 31. A second clamping unit 32 for clamping the lower end of the insulating film is slidably connected to one side of the second driving unit 31. The second clamping unit 32 includes a second clamping member 39 and a fourth driving member 35. Among them, the second clamping member 39 includes a first clamping plate 33 and a second clamping plate 34. The first clamping plate 33 and the second clamping plate 34 are arranged vertically opposite to each other. The first clamping plate 33 is slidably connected to the second driving unit 31. The fourth driving member 35 is fixedly arranged on one side of the first clamping plate 33. The fourth driving member 35 can drive the second clamping plate 34 to abut against the first clamping plate 33, so as to clamp the lower end of the insulating film. The second clamping unit 32 moves vertically downward along the second driving unit 31, so that the insulating film is vertically tightened. At the upper end of the second driving unit 31, a flattening unit 36 for flattening the insulating film is provided. The flattening unit 36 includes a pressing block 37 and a seventh driving member 38. The seventh driving member 38 is fixedly arranged at the upper end of the second driving unit 31. The pressing block 37 is made of smooth rubber. The pressing block 37 can extend towards the insulating film under the drive of the seventh driving member 38, and scrape the surface of the insulating film while the second clamping unit 32 pulls out the insulating film, so as to make the surface of the insulating film flat.

[0029] The working principle of the large bread film wrapping device is as follows: The first tensioning mechanism 2 is connected to an insulating film unwinding mechanism (not shown). The insulating film unwinding mechanism unwinds the insulating film to the first tensioning mechanism 2. At this time, the second clamping unit 32 moves upward and clamps the lower end of the insulating film. Then the second clamping unit 32 resets and pulls the insulating film downward, so that the insulating film passes through the avoidance notch 13 from top to bottom and vertically blocks the advancing direction of the transfer track 12. The first clamping unit 24 clamps the insulating film from the upper end. The cutting unit 27 cuts the insulating film to separate it from the film material. At this time, a feeding mechanism (not shown) places the product on the positioning mechanism 4. The positioning mechanism 4 positions the product. At the same time, the clamping unit 14 clamps the product from both sides. Then the positioning mechanism 4 releases the product. The product moves along the transfer track 12 under the drive of the clamping unit 14. The bottom surface of the product facing forward abuts against the insulating film. At this time, the first tensioning mechanism 2 and the second tensioning mechanism 3 release the insulating film. The clamping unit 14 continues to move. The product drives the insulating film to move forward. The second pressing roller unit 26 moves downward and presses the insulating film against the upper surface and the lower surface of the product, so as to realize the rapid film wrapping of the bottom surface, the upper surface and the lower surface of the product.

[0030] It should be noted that the above driving member can adopt a motor or a cylinder, or other common mechanical driving methods, which are not limited here.

[0031] In summary, the large bread film wrapping device of the present invention has a clever structure, effectively simplifies the process of large bread film wrapping of products, and improves the efficiency of film wrapping.

[0032] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings.
