Description

Technical Field

[0001] This utility model relates to the field of automated packaging technology, and in particular to a square aluminum-cased battery-compatible large bread film device. Background Technology

[0002] The square aluminum-cased battery coating device is a key piece of equipment in lithium battery manufacturing. Through mechanical positioning, film application, and sealing processes, it completely covers the surface of the battery casing with an insulating protective film, achieving electrical isolation and environmental protection. With the rapid development of the new energy industry, the diversification of battery application scenarios requires the coating process to balance airtight protection with functional opening. The opening structure selectively exposes areas of the battery casing by precisely removing film material in certain areas to meet heat dissipation or electrical connection requirements.

[0003] Existing coating equipment is limited in function, requiring separate equipment for different coating modes: U-shaped coating devices only support U-shaped wrapping, loop-shaped coating devices only support loop-shaped wrapping, and the window opening function requires dedicated equipment to open windows at specific locations. This discrete layout forces manufacturers to repeatedly configure multiple systems, resulting in significant redundancy in capital investment and factory space resources, and also causing scheduling efficiency constraints in multi-device collaboration. Therefore, there is an urgent need to develop a large-scale coating device that is fully compatible with square aluminum-cased batteries. Summary of the Invention

Obviously, the embodiments described below are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0069] In the description of this utility model, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0070] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0071] This embodiment provides a large-scale wrapping device that is fully compatible with square aluminum-cased batteries, used for wrapping square aluminum-cased batteries, and can realize multiple wrapping methods and multiple window opening methods. Combined with... Figures 1-2 As shown, the square aluminum-cased battery fully compatible large bread wrap device includes a wrapping position 11, a first positioning component 12, a first film feeding assembly 31, a second film feeding assembly 32, a first release paper winding assembly 41, a second release paper winding assembly 42, a third release paper winding assembly 43, a film cutting assembly 5, a wrapping assembly 6, a pushing assembly 2, a receiving assembly 7, a waste film winding roller 8, and a frame 1. The wrapping position 11 is equipped with a support platform for the movement of the battery 9, used to place the battery 9, and the battery 9 can move on the support platform under external force for subsequent wrapping operations.

[0072] Combination Figure 3 As shown, the first positioning member 12 is located between the pushing assembly 2 and the coating position 11. The first positioning member 12 is used for placing and positioning the battery 9. The pushing assembly 2 is used to transport the battery 9 from the first positioning member 12 to the coating position 11, realizing the movement of the battery 9. The pushing assembly 2 includes a first slide rail 21, a push block 22 slidably connected on the first slide rail 21, and a first power source 23 for driving the push block 22 to slide. The first slide rail 21, in addition to providing support and guidance when the push block 22 moves, also provides support and guidance for the battery 9. The push block 22 is used to push the battery 9 to move, and the first power source 23 provides linear motion power for the push block 22. The pushing assembly 2 completes the battery 9 transport process through the linear sliding mechanism of the first slide rail 21.

[0073] Combination Figures 4-5As shown, the first film-laying assembly 31 is located above the film-coating position 11 and is used to release the film material and transport the insulating film through the first film-laying path 311 or the second film-laying path 312. The first film-laying assembly 31 includes a first film-laying roller 313 and a second power source 314 for driving the first film-laying roller 313 to rotate. The first film-laying roller 313 is wrapped with film material on its outer side. The film material described in this utility model is a composite of insulating film and release paper. The insulating film has an adhesive surface for being applied to the outer surface of the battery 9. The release paper is applied to the adhesive surface of the insulating film to protect the adhesive surface. Before use, the release paper needs to be removed to expose the adhesive surface for bonding. The second power source 314 is used to provide power for the rotation of the first film-laying roller 313. Several guide rollers are provided on both the first film-laying path 311 and the second film-laying path 312 to guide the movement of the film material and ensure its flat transport. The end of the first film-laying path 311 is located above the coating position 11. The first film-laying assembly 31 can transport the insulating film to the coating position 11 via the first film-laying path 311, providing the insulating film required for coating the upper surface of the battery 9. The second film-laying path 312 extends from above the coating position 11 to the lower side of the coating position 11. The end of the second film-laying path 312 is vertically set, and the end of the second film-laying path 312 is located on the side of the coating position 11 away from the pushing assembly 2. That is, the first film-laying assembly 31 can transport the insulating film to the side of the coating position 11 away from the pushing assembly 2 via the second film-laying path 312. When the pushing assembly 2 continues to push the battery 9 towards the end of the second film-laying path 312, the battery 9 can contact the insulating film and complete part of the coating process. Different coating methods can be achieved depending on the different faces of the battery 9 facing the insulating film, that is, the different orientations of the battery 9. Among them, when the bottom face of the battery 9 faces the insulating film, a U-shaped coating can be achieved; when the side face of the battery 9 faces the insulating film, a U-shaped coating can be achieved. It should be noted that the square aluminum-cased battery in this embodiment has a square structure with six surfaces, including two large surfaces, two side surfaces, a top surface, and a bottom surface. The top surface has positive and negative electrodes, and the bottom surface is opposite to the top surface. Of the two pairs of surfaces arranged opposite to each other around the perimeter, the two with larger areas are the large surfaces, and the other two are the side surfaces.

[0074] The second film-laying assembly 32 is located below the coating position 11 and is used to release the film material and transport the insulating film through the third film-laying path 321. The third film-laying path 321 is equipped with several guide rollers to guide the movement of the film material and ensure its flat transport. The end of the third film-laying path 321 is located below the coating position 11. The second film-laying assembly 32 can transport the insulating film to below the coating position 11 through the third film-laying path 321, providing the required insulating film for coating the lower surface of the battery 9. The end of the third film-laying path 321 corresponds to the end of the first film-laying path 311. Specifically, the first film-laying assembly 31 transports the insulating film to above the coating position 11 through the first film-laying path 311, and the second film-laying assembly 32 transports the insulating film to below the coating position 11 through the third film-laying path 321. At this time, the insulating film is simultaneously adhered to the upper and lower surfaces of the battery 9, achieving double-film coating. Generally, when the battery 9 is located on the coating position 11, its two large faces face upwards and downwards respectively. This arrangement makes the battery 9 more stable and reduces the need for openings on the large faces, as these surfaces typically do not require holes or windows. Of course, if necessary, other faces of the battery 9 can also face upwards or downwards. The second film-laying assembly 32 includes a second film-laying roller 322 and a third power source 323 that drives the second film-laying roller 322 to rotate. The second film-laying roller 322 is wrapped with a film material, which is also a composite of insulating film and release paper. The third power source 323 provides the rotational power for the second film-laying roller 322.

[0075] The first release liner winding assembly 41 is located on one side of the first film feeding path 311. The first release liner winding assembly 41 provides tension to separate the release liner from the insulating film and winds up the separated release liner to avoid interference. The first release liner winding assembly 41 includes a first release liner winding roller 411 and a fourth power source 412 for driving the first release liner winding roller 411 to rotate. In this embodiment, the first release liner winding roller 411 can wind up the release liner located above the wrapping position 11 when double-film wrapping is used. The fourth power source 412 provides rotational power to the first release liner winding roller 411 to wind up the release liner above the double-film wrapping.

[0076] The second release paper winding assembly 42 is located on one side of the second film feeding path 312. The second release paper winding assembly 42 separates the release paper from the insulating film by providing tension, and winds up the separated release paper to avoid interference. The second release paper winding assembly 42 includes a second release paper winding roller 421 and a fifth power source 422 for driving the second release paper winding roller 421 to rotate. In this embodiment, the outer side of the second release paper winding roller 421 can wind up the release paper when U-shaped or loop-shaped wrapping. The fifth power source 422 is used to provide rotational power to the first release paper winding roller 411 to wind up the release paper when U-shaped or loop-shaped wrapping.

[0077] The third release paper winding assembly 43 is located on one side of the third film feeding path 321. The third release paper winding assembly 43 separates the release paper from the insulating film by providing tension, and winds up the separated release paper to avoid interference. The third release paper winding assembly 43 includes a third release paper winding roller 431 and a sixth power source 432 that drives the third release paper winding roller 431 to rotate. The outer side of the third release paper winding roller 431 can wind up the release paper located below the wrapping position 11 when double-film wrapping is performed. The sixth power source 432 is used to provide rotational power to the third release paper winding roller 431 to wind up the release paper below when double-film wrapping is performed.

[0078] Combination Figures 6-9The film cutting assembly 5 is used to cut insulating films at the ends of the first film feeding path 311, the second film feeding path 312, and the third film feeding path 321. The film cutting assembly 5 includes: a first cutting blade 511 facing the end of the first film feeding path 311, and a seventh power source 512 driving the first cutting blade 511 to cut the corresponding insulating film; a second cutting blade 521 facing the end of the second film feeding path 312, and an eighth power source 522 driving the second cutting blade 521 to cut the corresponding insulating film; and a third cutting blade 531 facing the end of the third film feeding path 321, and a ninth power source 532 driving the third cutting blade 531 to cut the corresponding insulating film. The first cutting blade 511, the second cutting blade 521, and the third cutting blade 531 are respectively used to cut insulating films at the ends of the first film feeding path 311, the second film feeding path 312, and the third film feeding path 321. In this embodiment, the blade width of the first cutting blade 511 and the third cutting blade 531 is not less than the width of the corresponding insulating film. The seventh power source 512 and the ninth power source 532 drive the first cutting blade 511 and the third cutting blade 531 to move closer to or further away from the corresponding insulating film, so as to achieve the cutting of the corresponding insulating film. The second cutting blade 521 includes a horizontally arranged planar cutter 5211 and / or a vertically arranged vertical cutter 5212, used to cut the insulating film at the end of the second film feeding path 312; wherein the planar cutter 5211 is used to cut the insulating film in the horizontal direction; the vertical cutter 5212 is used to cut the insulating film in the vertical direction, and different cutting directions can be selected according to needs. In addition, both the horizontal cutter 5211 and the vertical cutter 5212 require vertical and horizontal displacement. The horizontal movement direction of the horizontal cutter 5211 and the vertical cutter 5212 is perpendicular to the movement direction of the pusher assembly 2 pushing the battery 9. The eighth power source 522 is a dual-axis moving table to provide independent displacement control in two directions. The dual-axis moving table includes two sets of drive units. The two sets of drive units can select linear motors, hydraulic cylinders, air cylinders, rotary motors driving ball screws, or rotary motors driving belt / chain drives, etc., according to application requirements. Through their respective mechanical structures, they realize axial linear motion transmission and finally work together to complete the precise displacement adjustment of the horizontal cutter 5211 and the vertical cutter 5212 in the horizontal and vertical directions to ensure the cutting action.

[0079] The coating assembly 6 is used to adhere the insulating film to the surface of the battery 9. The coating assembly 6 includes: a first pressure roller 611 located above the coating position 11, and a tenth power source 612 for driving the first pressure roller 611 closer to / away from the battery 9; a second pressure roller 621 located below the coating position 11, and an eleventh power source 622 for driving the second pressure roller 621 closer to / away from the battery 9; a third pressure roller 631 located above the coating position 11, and a twelfth power source 632 for driving the third pressure roller 631 to move up and down; and a fourth pressure roller 641 located below the coating position 11, and a thirteenth power source 642 for driving the fourth pressure roller 641 to move up and down; wherein the third pressure roller 631 and the fourth pressure roller 641 are located on the side of the second film feeding path 312 away from the pushing assembly 2. In this embodiment, the first pressing roller 611 and the second pressing die can be used to coat the upper and lower surfaces of the battery 9 when using double-film coating. Generally, the upper and lower surfaces of the battery 9 are two large surfaces. The third pressing roller 631 and the fourth pressing roller 641 can be used to coat the front and rear surfaces or one of the surfaces of the battery 9 when using double-film coating, U-shaped coating, or U-shaped coating. Generally, in U-shaped coating, it is used for coating the bottom and / or top surface, and in U-shaped coating, it is used for coating the two sides or one of the sides. Alternatively, the third pressing roller 631 and the fourth pressing roller 641 can be used to coat the upper and lower surfaces when using U-shaped or U-shaped coating. The coating assembly 6 presses the insulating film onto the surface of the battery 9 using the first pressing roller 611, the second pressing die, the third pressing roller 631, and the fourth pressing roller 641, and the insulating film adheres to the surface of the battery 9 using its own adhesive side, thereby achieving the coating of the battery 9. It should be noted that the front and back of battery 9 here are in the same direction as the forward or backward movement of battery 9.

[0080] Combination Figure 10As shown, the receiving component 7 is positioned opposite the pushing component 2 and located on the side of the wrapping position 11 away from the pushing component 2. It is used to receive and transfer the wrapped battery 9 to the downstream process. The receiving component 7 includes a second slide rail 71, a second positioning member 72 slidably connected on the second slide rail 71, and a fourteenth power source 73 for driving the second positioning member 72 to slide. The second positioning member 72 is used for positioning the battery 9, and the fourteenth power source 73 provides linear motion power for the second positioning member 72. The waste film winding roller 8 is located below the wrapping position 11 and is positioned opposite the end of the second film feeding path 312. It is used to collect excess waste insulating film after cutting and keep the working area clean. The waste film winding roller 8 is set at the output end of the power source, such as on the output shaft of a motor, for automatic winding of waste film.

At least one of the upper frame 13 and the lower frame 14 is slidably connected to a third slide rail 15 and driven to slide by a fifteenth power source 16. The fifteenth power source 16 operates by driving the upper frame 13 and / or the lower frame 14 to slide on the third slide rail 15, thereby adjusting the size of the film wrapping position 11 to accommodate batteries of different sizes. In this embodiment, the third slide rail 15 is fixed on the frame 1.

[0081] This invention controls the position and size of the exposed area by precisely adjusting the width and length of the insulating film, so that the surface of the battery 9 has an uncovered window of a specific position and size after the film is wrapped. This avoids the cutting process and ensures the integrity of the edge and no damage to the battery 9 casing, while also reducing the consumption of film material caused by cutting.

[0082] Furthermore, combining Figure 11 As shown, when a U-shaped wrapping is required, the battery 9 is placed on the second positioning member 72, with the top surface of the battery 9 close to the wrapping position 11. Then, the pushing assembly 2 pushes the battery 9 to the wrapping position 11. The first film feeding assembly 31 releases the film material and drives the insulating film to be conveyed along the second film feeding path 312. The second release paper winding assembly 42 provides tension to separate the release paper from the insulating film and simultaneously winds up the separated release paper to avoid interference. This continues until the film is conveyed to the end of the second film feeding path 312. At this point, the insulating film is located on the side of the wrapping position 11 away from the pushing assembly 2. The pushing assembly 2 continues to push the battery 9 so that the battery 9 comes into contact with the insulating film. According to the required insulating film length, the second film cutting knife 521 cuts the insulating film, and the third pressure roller 631 and the fourth pressure roller 641 press the insulating film against the surface of the battery 9 to achieve U-shaped wrapping. Figure 11 As shown in (a). If a window is required, the required length and width of the insulating film are determined according to the required window size, so that after the battery 9 is coated, there are some uncoated areas. These areas form specific window areas to expose the functional structures (such as electrodes or heat dissipation interfaces) on the surface of the battery 9. Top and side windows can be implemented as needed, i.e., two-sided windows.

[0083] When a spiral wrapping is required, such as Figure 11 As shown in (b), the difference from using a U-shaped wrapping is that when the battery 9 is placed on the second positioning member 72, the side of the battery 9 is close to the wrapping position 11. In addition, when using a U-shaped wrapping, if a window needs to be opened, windows can be opened on the top and bottom surfaces.

[0084] When a double-layer coating is required, such as Figure 11 As shown in (c), the battery 9 is placed on the second positioning member 72, with the top surface of the battery 9 close to the coating position 11. Then, the pushing assembly 2 pushes the battery 9 to the coating position 11. The first film-releasing assembly 31 releases the film material and drives the insulating film to be conveyed along the first film-releasing path 311 until the insulating film is conveyed above the coating position 11. The second film-releasing assembly 32 releases the film material and drives the insulating film to be conveyed along the third film-releasing path 321 until the insulating film is conveyed below the coating position 11. The first release paper winding assembly 41 provides tension to separate the release paper from the insulating film at the top and bottom respectively, and simultaneously winds up the separated release paper to avoid interference. If a window is required, the required length and width of the insulating film are determined according to the required window size, so that there is a part of the battery 9 that is not coated after coating. This part forms a specific window area to expose the functional structure (such as electrodes or heat dissipation interface) on the surface of the battery 9. Specifically, when some uncoated areas are located on the top and side surfaces, two-sided windows are achieved; when some uncoated areas are located on the bottom and top surfaces, windows on the bottom and top surfaces are achieved; and when some uncoated areas are located on the bottom, top, and side surfaces, windows on three sides are achieved.

[0085] The square aluminum-cased battery fully compatible large bread wrap device described in this utility model can realize the selection and switching of U-shaped wrapping, U-shaped wrapping, and double-film wrapping; it can also open windows on two or three sides as needed. By precisely controlling the size of the film material, it can replace the physical window opening mechanism without adding an additional window opening mechanism, realizing multiple wrapping methods and flexible multi-sided window opening function with one device.
