Description

Technical Field

[0001] This application relates to the field of aluminum-plastic film folding technology, and in particular to a folding device for aluminum-plastic film with a center fold line, packaging equipment, and solid-state battery production line. Background Technology

[0002] In battery production, after the aluminum-plastic film is punched through by the punching equipment, the battery cell needs to be placed on the aluminum-plastic film. Then, the aluminum-plastic film is folded to cover the battery cell before encapsulation. However, current aluminum-plastic film is folded using a folding mechanism, but because the aluminum-plastic film is a single piece, its own stress causes the fold line to shift when folded into two sides. This results in misalignment of the two sides of the aluminum-plastic film after folding, affecting the consistency of the battery and failing to guarantee the production quality of the battery. Utility Model Content

[0003] To address one of the aforementioned technical problems, this application provides a folding device for an aluminum-plastic film centering fold line, comprising a folding assembly for supporting the aluminum-plastic film, a first displacement assembly, and a centering folding plate. The first displacement assembly is disposed on one side of the folding assembly, and the centering folding plate is disposed at the driving end of the first displacement assembly. The first displacement assembly drives the centering folding plate to abut against the centerline of the aluminum-plastic film, and the folding assembly folds the aluminum-plastic film to form a centering fold line. The folding assembly aligns the aluminum-plastic film along the centering fold line after the battery cell is installed in the casing. The aluminum-plastic film is then placed on the folding assembly, and the first displacement assembly drives the centering folding plate to abut against the centerline of the aluminum-plastic film. The folding assembly folds the aluminum-plastic film around the centering folding plate, thus forming a centering fold line on the aluminum-plastic film. After the battery cell is installed onto the aluminum-plastic film, the aluminum-plastic film is folded and aligned along the central fold line by the folding component, so that the aluminum-plastic film covers the battery cell, thereby ensuring that the two sides of the aluminum-plastic film are aligned after folding, improving the consistency of the battery.

[0004] Preferably, the first displacement component includes a lateral displacement module, a longitudinal displacement module disposed at the drive end of the lateral displacement module, and a lifting displacement module disposed at the drive end of the longitudinal displacement module, with the centering folding plate disposed at the drive end of the lifting displacement module. This enables the centering folding plate to be moved to adjust its position, allowing it to be precisely positioned on the centerline of the aluminum-plastic film. This adapts to and is compatible with the folding requirements of aluminum-plastic films of different thicknesses, improving the adaptability of the folding device. For example, the lateral displacement module, longitudinal displacement module, and lifting displacement module can employ a linear drive structure consisting of a motor and a lead screw, or they can be driven by a cylinder.

[0005] Preferably, a lifting plate is provided at the drive end of the lifting displacement module. Adjustment slots are provided at both ends of the lifting plate, and fasteners connected to the centering folding plate pass through these slots. After loosening the fasteners, the angle of the centering folding plate can be adjusted by rotating it. After adjustment, the centering folding plate is then locked in place by the fasteners. Simultaneously, the centering folding plate can be disassembled and replaced via the threaded connection between the fasteners and both ends, thus achieving the purpose of changing the type of plate.

[0006] Preferably, the folding assembly includes a fixedly mounted first template and a rotation drive module, and a second template disposed at the drive end of the rotation drive module. The rotation drive module drives the second template to flip relative to the first template. When the folding plate abuts against the center line of the aluminum-plastic film, the rotation drive module drives the second template to flip relative to the first template, causing the aluminum-plastic film to fold and form a fold line. After the folding plate is removed, the battery cell is installed onto the aluminum-plastic film. Then, the rotation drive module drives the second template to fold relative to the first template again, causing the aluminum-plastic film to fold and cover the battery cell, ensuring that the two sides of the folded aluminum-plastic film are aligned, thus improving battery consistency.

[0007] Preferably, the bearing surfaces of the first template and the second template are provided with a plurality of suction cups. An exhaust channel communicating with the suction cups is provided within the first template and the second template. A negative pressure generator is connected through the exhaust channel, thereby generating negative pressure to allow the suction cups to adhere to the aluminum-plastic film.

[0008] Preferably, the assembly further includes a horizontal displacement module and a fixed plate disposed at the drive end of the horizontal displacement module. The first template is disposed on the fixed plate, and the rotary drive module is connected to the fixed plate via a mounting plate. The horizontal displacement module can then drive the fixed plate to move, thereby moving the folding assembly to adjust its position. The horizontal displacement module can employ a drive mechanism consisting of a motor and a lead screw, or it can use a cylinder to drive the fixed plate. Simultaneously, the first template can be detachably mounted on the fixed plate via bolts or other connecting components, and the second template can be detachably connected to the drive end of the rotary drive module via a connecting plate and bolts. This allows for the replacement of first and second templates of different sizes, thus adapting to the flipping of aluminum-plastic films of different sizes and improving compatibility.

[0009] Preferably, an adjustment module is provided on the fixed plate, and a baffle frame is provided at the drive end of the adjustment module. A flipping cavity is formed between the baffle frame and the mounting plate. The adjustment module drives the baffle frame to move closer to or further away from the mounting plate to adjust the size of the flipping cavity. Therefore, according to the sizes of the first and second templates, the size of the flipping cavity can be adjusted by moving the baffle frame through the adjustment module, thereby adapting to the flipping requirements of templates of different sizes, and thus adapting to the flipping requirements of aluminum-plastic film of different sizes.

[0010] Preferably, both ends of the enclosure frame are slidably connected to the mounting plate via a sliding structure. The sliding structure can be a slide rail and a slider, allowing the enclosure frame to slide relative to the mounting plate. The adjustment module can be a cylinder, with its telescopic end connected to the enclosure frame, thereby driving the enclosure frame closer to or further away from the mounting plate to adjust the size of the flipping cavity.

[0011] Preferably, a packaging device includes the aforementioned aluminum-plastic film folding device for aligning the fold line. After the battery cell is inserted into the casing, the folding device folds the aluminum-plastic film to align it, ensuring the film covers the battery cell and that both sides of the folded film are aligned, thereby improving battery production consistency. The battery cell is then encapsulated by a sealing device.

[0012] Preferably, a solid-state battery production line includes the aforementioned aluminum-plastic film centering folding device. It is used for the casing, folding, and packaging of solid-state batteries, improving the consistency and quality of battery production.

The first displacement component is used to drive the centering folding plate to abut against the center line of the aluminum-plastic film, and the folding component folds the aluminum-plastic film to form a center fold line. The folding component is used to fold and align the aluminum-plastic film along the center fold line after the battery cell is installed in the casing. Then, the aluminum-plastic film is placed on the folding component, and the first displacement component drives the centering folding plate to abut against the center line of the aluminum-plastic film, and the folding component folds the aluminum-plastic film to form a center fold line. Then, the battery cell is installed on the aluminum-plastic film, and the folding component folds and aligns the aluminum-plastic film along the center fold line after the battery cell is installed in the casing, so that the aluminum-plastic film covers the battery cell, thereby ensuring that the two sides of the aluminum-plastic film are aligned after folding, improving the consistency of the battery.

However, it should be understood that these practical details should not be used to limit this application. That is, in some embodiments of this application, these practical details are not essential.

They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0021] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: To address the aforementioned technical problems, this embodiment provides a folding device for the centering fold line of an aluminum-plastic film, such as... Figure 1-2 As shown, the device includes a folding assembly 10, a first displacement assembly 20, and a centering folding plate 30. The folding assembly 10 carries the aluminum-plastic film. The first displacement assembly 20 is located on one side of the folding assembly 10, and the centering folding plate 30 is located at the driving end of the first displacement assembly 20. The aluminum-plastic film is then placed on the folding assembly 10. The first displacement assembly 20 drives the centering folding plate 30 to abut against the centerline of the aluminum-plastic film. The folding assembly folds the aluminum-plastic film around the centering folding plate, forming a center fold line on the aluminum-plastic film. After the battery cell is installed in the casing, the folding assembly 10 folds and aligns the aluminum-plastic film along the center fold line, ensuring that the aluminum-plastic film covers the battery cell. This ensures that the two sides of the folded aluminum-plastic film are aligned, improving battery consistency.

[0022] Specifically, such as Figure 3 As shown, the first displacement component 20 includes a lateral displacement module 21, a longitudinal displacement module 22 disposed at the driving end of the lateral displacement module 21, and a lifting displacement module 23 disposed at the driving end of the longitudinal displacement module 22. The centering folding plate 30 is disposed at the driving end of the lifting displacement module 23. For example, the driving directions of the lateral displacement module 21, the longitudinal displacement module 22, and the lifting displacement module 23 are perpendicular to each other, thus forming a three-axis displacement system. This system drives the centering folding plate 30 to move and adjust its position, allowing the centering folding plate 30 to be precisely positioned on the centerline of the aluminum-plastic film. This adapts to and is compatible with the folding requirements of aluminum-plastic films of different thicknesses, improving the adaptability of the folding device. For example, the lateral displacement module 21, the longitudinal displacement module 22, and the lifting displacement module 23 can be a linear drive structure composed of a motor and a lead screw, or they can be driven by a cylinder, or other drive mechanisms to achieve displacement. This embodiment does not limit the specific implementation.

[0023] Furthermore, in order to adjust the angle of the middle fold plate 30, such as Figure 3 As shown, a lifting plate 24 is provided at the drive end of the lifting displacement module 23. Angle adjustment slots 25 are provided at both ends of the lifting plate 24, and fasteners 26 that connect to the centering folding plate 30 pass through the angle adjustment slots 25. For example, the fasteners 26 can be bolts. After loosening the fasteners 26, the angle position of the centering folding plate 30 can be adjusted by rotating it. After adjustment, the centering folding plate 30 is locked and fixed by the fasteners 26. Simultaneously, the centering folding plate 30 can be disassembled and replaced by the threaded connection between the fasteners 26 and both ends of the fasteners 26, thereby achieving the purpose of changing the type of the plate.

[0024] Furthermore, such as Figure 2 As shown, the folding assembly 30 includes a fixedly set first template 11 and a rotation drive module 13, and a second template 12 set at the drive end of the rotation drive module 13. The exemplary rotation drive module 13 can be a motor. There are two rotation drive modules 13, which are respectively connected to the two ends of the second template 12. When the center folding plate 30 abuts against the center line of the aluminum-plastic film, the rotation drive module 13 drives the second template 12 to flip relative to the first template 11, so that the aluminum-plastic film is folded and forms a center fold line. After the center folding plate 30 is removed, the battery cell is installed on the aluminum-plastic film. Then, the rotation drive module 13 drives the second template 12 to fold relative to the first template 11, so that the aluminum-plastic film covers the battery cell and ensures that the two sides of the aluminum-plastic film are aligned after folding, thereby improving the consistency of the battery.

[0025] In the above scheme, when the aluminum-plastic film is placed on the first template 11 and the second template 12, in order to achieve adsorption and fixation of the aluminum-plastic film, as follows: Figure 4-5 As shown, the bearing surfaces of the first template 11 and the second template 12 are provided with a number of suction cups 15. An exhaust channel is provided in the first template 11 and the second template 12 to connect the suction cups 15. The exhaust channel is connected to a negative pressure generator, and then the suction cups 15 are used to adsorb the aluminum-plastic film by generating negative pressure.

[0026] Specifically, the folding device in this embodiment further includes a horizontal displacement module 40 and a fixed plate 50 disposed at the driving end of the horizontal displacement module 40. The first template 11 is disposed on the fixed plate 50, and the rotation drive module 13 is connected to the fixed plate 50 through a mounting plate 14. Thus, the fixed plate 50 can be moved by the horizontal displacement module 40, thereby driving the folding assembly 30 to move to adjust its position. For example, the horizontal displacement module 40 can be a drive mechanism composed of a motor and a lead screw, or it can be driven by a cylinder to drive the fixed plate 50 to move.

[0027] In the above scheme, the first template 11 can be detachably installed on the fixed plate 50 by means of bolts or other connecting parts, and the second template 12 can be detachably connected to the drive end of the rotation drive module 13 by means of connecting plate and bolts. In this way, the first template 11 and the second template 12 of different sizes can be replaced, thereby adapting to the flipping of aluminum-plastic film of different sizes and improving compatibility.

[0028] Furthermore, an adjustment module 70 is provided on the fixed plate 50, and a baffle frame 60 is provided at the driving end of the adjustment module 70. The baffle frame 60 and the mounting plate 14 form a flipping cavity 61. The adjustment module 70 drives the baffle frame 60 to move closer to or further away from the mounting plate 14. Thus, according to the size of the first template 11 and the second template 12, the baffle frame 60 is moved by the adjustment module 70 to adjust the area of ​​the flipping cavity 61, so as to meet the flipping requirements of templates of different sizes, and thus meet the flipping requirements of aluminum-plastic film of different sizes.

[0029] Furthermore, the two ends of the enclosure frame 60 are slidably connected to the mounting plate 14 via sliding structures 62. For example, the enclosure frame 60 is U-shaped, and sliding structures 62 are provided on both sides of the enclosure frame 60, allowing the enclosure frame 60 to be slidably connected to both sides of the mounting plate 14 via these sliding structures 62. In some embodiments, the sliding structure 62 can be a slide rail and a slider, thereby allowing the enclosure frame 60 to slide relative to the mounting plate 14. The adjustment module 70 can be a cylinder, with its telescopic end connected to the enclosure frame 60, thereby driving the enclosure frame 60 closer to or further away from the mounting plate 14 to adjust the area of ​​the flipping cavity 61.

[0030] On the other hand, this embodiment provides a packaging device, including the above-mentioned aluminum-plastic film centering folding device. After the battery cell is inserted into the casing, the aluminum-plastic film is folded in the center by the folding device, so that the aluminum-plastic film covers the battery cell. After folding, the two sides of the aluminum-plastic film are aligned, thereby improving the consistency of battery production. Then, the battery cell is packaged by the packaging device.

[0031] On the other hand, this embodiment provides a solid-state battery production line, including the above-mentioned aluminum-plastic film centering folding device and packaging equipment, for the production of solid-state batteries through casing, folding and encapsulation, thereby improving the consistency of battery production and improving the production quality of batteries.

The folding component carries the aluminum-plastic film, the first displacement component is located on one side of the folding component, and the centering folding plate is located at the driving end of the first displacement component. The aluminum-plastic film is then placed on the folding component, and the centering folding plate is driven by the first displacement component to abut against the center line of the aluminum-plastic film. The folding component folds the aluminum-plastic film to form a center fold line. After the battery cell is installed in the casing, the folding component folds and aligns the aluminum-plastic film along the center fold line, so that the aluminum-plastic film covers the battery cell, thereby ensuring that the two sides of the aluminum-plastic film are aligned after folding, improving the consistency of the battery.
