AI Technical Summary
Existing technologies have problems such as uneven material tension and errors in the accuracy of the winding needle leading to concave outer circle or excessive ellipticity during the shaping process of cylindrical battery cells. Furthermore, existing shaping devices are difficult to achieve uniform pressure distribution, which can easily cause stress concentration and battery cell deformation.
The first and second shaping roller groups rotate synchronously under a rotary drive, and the linear drive component drives the roller groups to move towards each other, so as to achieve uniform circumferential rolling and self-rotation shaping of the battery cell, avoiding stress concentration and asymmetric force problems.
This achieves uniform force shaping of the battery cell, prevents twisting and deformation, improves shaping efficiency and battery cell structural stability, and ensures smooth subsequent assembly processes.

Abstract
Description
Technical Field
[0001] This application relates to the field of battery cell production, and more particularly to a battery cell shaping device and production equipment. Background Technology
[0002] During lithium battery manufacturing, cylindrical cells often exhibit localized depressions or excessive ellipticity on their outer circumference after winding due to factors such as uneven material tension and errors in the precision of the winding needles. This significantly deviates from the ideal cylindrical geometry. Such deformation not only affects the structural stability of the cell but also hinders subsequent assembly processes—forcibly inserting deformed cells into the casing may scratch the separator or cause misalignment of the tabs, creating a potential risk of thermal runaway.
[0003] The current industry standard for shaping cylindrical cells is based on a prismatic cell forming technology. This technology, which relies on bidirectional pressure from a planar plate, fundamentally clashes with the cylindrical structure. The circumferential continuity of the cylindrical surface requires a uniform distribution of forming force, while the planar plate can only apply force in a limited contact area, easily leading to stress concentration, causing electrode powder detachment or diaphragm perforation. Although some manufacturers have attempted to process cylindrical cells using simple roller devices or manual rolling, these methods have significant drawbacks: manual operation is inefficient and pressure consistency is difficult to control; simple rollers often use single-sided drive, causing the cell to experience asymmetrical forces during rotation, which exacerbates spiral torsion and deformation.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0017] When the driven seat is disposed at the second moving end, the first driven wheel is disposed at the end of the third roller shaft, and the second driven wheel is disposed at the end of the fourth roller shaft.
[0018] Furthermore, two feeding components are provided on the outer side of the first side, and the two feeding components are located at both ends of the substrate.

[0038] This application provides a battery cell shaping apparatus, which includes a substrate 100, a first linear drive assembly 200, a shaping assembly 300, and a rotary drive assembly 400. The substrate 100 has a first side surface, and the first linear drive assembly 200 is disposed on the first side surface. The first linear drive assembly 200 has a first moving end and a second moving end. The shaping assembly 300 includes a first shaping roller group 310 and a second shaping roller group 320. The first shaping roller group 310 and the second shaping roller group 320 define a shaping area. The first shaping roller group 310 is disposed on the first moving end, and the second shaping roller group 320 is disposed on the second moving end. The rotary drive assembly 400 is disposed on the first moving end for driving the first shaping roller group 310 to rotate, or the rotary drive assembly 400 is disposed on the second moving end for driving the second shaping roller group 320 to rotate.
[0039] In this embodiment, the rotating drive assembly 400 drives the first shaping roller group 310 to rotate as an example, and the first side is the lower surface of the substrate 100.
[0040] Please see Figure 1 and Figure 2 As shown, after the battery cell is lifted into the shaping area formed by the first shaping roller group 310 and the second shaping roller group 320, the first linear drive assembly 200 drives the first shaping roller group 310 and the second shaping roller group 320 to move closer to each other, so that the battery cell contacts and abuts against the roller surface of the first shaping roller group 310 and the roller surface of the second shaping roller group 320. When the first shaping roller group 310 rotates, it drives the battery cell located in the shaping area to rotate, and shaping is achieved during the rotation of the battery cell.
[0041] Compared with the manual rolling method, the method of rotating the first shaping roller group 310 to drive the battery cell rotation in this application results in a more uniform contact force on the surface of the battery cell due to the combination of the first shaping roller group 310 and the second shaping roller group 320, which prevents the battery cell surface from twisting and deforming due to uneven force.
[0042] In some specific embodiments, the first linear drive assembly 200 includes a first linear drive member 210 and a second linear drive member 220, which are respectively disposed at both ends of the first side.
[0043] See Figure 1 and Figure 2 As shown, in order to ensure that the first shaping roller group 310 and the second shaping roller group 320 apply uniform contact force to the battery cell, a first linear drive member 210 and a second linear drive member 220 are fixedly installed on the first side of the substrate 100, and the first linear drive member 210 and the second linear drive member 220 are spaced apart on the first side. Specifically, the first linear drive member 210 and the second linear drive member 220 are located at the left and right ends of the first side, respectively, so that the battery cell is completely located in the shaping area in the axial direction, and a uniform contact force is applied to the surface of the battery cell, so that the battery cell can be uniformly shaped by force during rotation.
[0044] For example, both the first linear drive unit 210 and the second linear drive unit 220 are cylinders, each with a drive end. The first linear drive unit 210 and the second linear drive unit 220 can be controlled to extend or retract simultaneously, thereby synchronously driving the two ends of the first shaping roller group 310 and the two ends of the second shaping roller group 320 to move simultaneously. This prevents the first shaping roller group 310 or the second shaping roller group 320 from tilting in the axial direction due to their inability to extend or retract synchronously, which would result in uneven force applied to the surface of the battery cell and cause the battery cell to twist and deform. It is understood that the first linear drive unit 210 and the second linear drive unit 220 can also be other types of linear drive structures, such as linear drive devices such as motor lead screw linear modules. The type and model of the first linear drive unit 210 and the second linear drive unit 220 are not limited here.
[0045] In some specific embodiments, the first shaping roller group 310 includes a first mounting base 311 disposed at the first moving end, and a first roller shaft 312 and a second roller shaft 313 are rotatably disposed on the first mounting base 311 at intervals. The second shaping roller group 320 includes a second mounting base 321 disposed at the second moving end, and a third roller shaft 322 and a fourth roller shaft 323 are rotatably disposed on the second mounting base 321 at intervals.
[0046] Please see Figure 2 , Figure 3 as well as Figure 4 As shown, the first shaping roller group 310 and the second shaping roller group 320 are located on the front and rear sides of the bottom surface of the substrate 100, and the first shaping roller group 310 and the second shaping roller group 320 are spaced apart to form a shaping area. Specifically, there are two first mounting seats 311, which are fixedly disposed at the left and right ends of the bottom of the substrate 100. Correspondingly, the two ends of the first roller shaft 312 and the second roller shaft 313 are rotatably connected to the first mounting seats 311 corresponding to their respective positions. The first roller shaft 312 and the second roller shaft 313 are spaced apart in the vertical direction. The two first mounting seats 311 are driven by the first linear drive member 210 and the second linear drive member 220 corresponding to their respective positions. The first linear drive member 210 and the second linear drive member 220 synchronously extend and retract to drive the two first mounting seats 311 to move, thereby driving the first roller shaft 312 and the second roller shaft 313 to move.
[0047] Similarly, there are two second mounting bases 321, which are fixedly disposed at the left and right ends of the bottom of the substrate 100. The two ends of the third roller shaft 322 and the fourth roller shaft 323 are respectively rotatably connected to the second mounting base 321 corresponding to their respective positions. The third roller shaft 322 and the fourth roller shaft 323 are spaced apart in the vertical direction. The two second mounting bases 321 are connected to the driving ends of the corresponding first linear drive member 210 and second linear drive member 220. It can be understood that the first roller shaft 312, the second roller shaft 313, the third roller shaft 322 and the fourth roller shaft 323 define the forming area mentioned above.
[0048] Specifically, by synchronously extending and retracting the first linear drive member 210 and the second linear drive member 220, the first mounting base 311 and the second mounting base 321 can move closer to or further away from each other, thereby driving the first roller shaft 312, the second roller shaft 313, the third roller shaft 322, and the fourth roller shaft 323 to move closer to or further away from each other.
[0049] In some specific embodiments, the rotary drive assembly 400 includes a driven seat 410 slidably disposed on the substrate 100, a rotary drive member 420 mounted on the driven seat 410, a drive wheel 430 disposed at the power output end of the rotary drive member 420, and a first driven wheel 440 and a second driven wheel 450 being connected to the drive wheel 430 in a driving transmission manner; when the driven seat 410 is disposed at the first moving end, the first driven wheel 440 is disposed at the end of the first roller shaft 312, and the second driven wheel 450 is disposed at the end of the second roller shaft 313.
[0050] Continue reading Figures 2 to 4As shown, in this application, the first driven wheel 440 is fixedly installed at the end of the first roller shaft 312, and the second driven wheel 450 is fixedly installed at the end of the second roller shaft 313. The first driven wheel 440 and the second driven wheel 450 are located on the same side, and both the first driven wheel 440 and the second driven wheel 450 are connected to the driving wheel 430 for transmission. That is, the rotation of the driving wheel 430 can simultaneously drive the first driven wheel 440 and the second driven wheel 450 to rotate. In order to keep the driving wheel 430 always connected to the first driven wheel 440, the second driven wheel 450 is rotated. 0. When the second driven wheel 450 is in a driving connection state, the driven seat 410 is fixedly connected to the first mounting seat 311. That is, at this time, the rotary drive member 420 moves together with the first mounting seat 311, so that the drive wheel 430 remains in a driving connection state with the first driven wheel 440 and the second driven wheel 450. Specifically, the rotary drive member 420 drives the drive wheel 430 to rotate, and under the driving action of the first driven wheel 440 and the second driven wheel 450, it drives the first roller shaft 312 and the second roller shaft 313 to rotate.
[0051] For example, the driving wheel 430, the first driven wheel 440 and the second driven wheel 450 are all gears, and the driving wheel 430 meshes with the first driven wheel 440 and the second driven wheel 450 for transmission.
[0052] In this embodiment, in order to make the follower seat 410 move more stably with the first mounting seat 311, a sliding component 700 connected to the follower seat 410 is provided on the bottom surface of the substrate 100. Specifically, the sliding component 700 includes a guide rail 710 and a slider 720. The guide rail 710 and the slider 720 are slidably connected. The guide rail 710 is fixedly disposed on the bottom surface of the substrate 100, and the slider 720 is fixedly connected to the follower seat 410.
[0053] In another embodiment, when the driven seat 410 is disposed at the second moving end, the first driven wheel 440 is disposed at the end of the third roller shaft 322, and the second driven wheel 450 is disposed at the end of the fourth roller shaft 323. Accordingly, in order to keep the driving wheel 430 in a transmission connection with the first driven wheel 440 and the second driven wheel 450, the driven seat 410 is fixedly connected to the second mounting seat 321, and the driven seat 410 and the rotary drive member 420 move synchronously with the second mounting seat 321.
[0054] In some specific embodiments, two feeding components 500 are provided on the outer side of the first side. The two feeding components 500 are located at both ends of the substrate 100. The feeding components 500 are used to drive the battery cell to move toward or away from the shaping area. The feeding components 500 include a third linear drive member 510. A follower member 520 is installed at the driving end of the third linear drive member 510. A support member 530 is provided at the end of the follower member 520. A support groove 531 is provided on the support member 530.
[0055] Please see Figure 1 and Figure 5 As shown, when the battery cell is conveyed to the area below the shaping zone, the driven member 520 and the support member 530 can be lifted upwards by the third linear drive member 510 on both sides, so that both ends of the battery cell are placed in the support groove 531. As the third linear drive member 510 continues to lift the driven member 520 and the support member 530 upwards, the battery cell is lifted to the shaping zone. Finally, the first linear drive member 210 and the second linear drive member 220 contract synchronously, causing the first shaping roller group 310 and the second shaping roller group 320 to move closer to each other, thereby clamping the battery cell. Under the transmission action of the drive wheel 430, the first driven wheel 440 and the second driven wheel 450, the first roller shaft 312 and the second roller shaft 313 are rotated by the rotation drive member 420. The device can rotate and shape the battery cell located in the shaping area. During the shaping process, the third linear drive 510 drives the driven member 520 and the support member 530 back to their initial positions. After the battery cell is rotated and shaped, the third linear drive 510 will drive the driven member 520 and the support member 530 to lift the battery cell to its position. After the first linear drive 210 and the second linear drive 220 extend and the first shaping roller group 310 and the second shaping roller group 320 move away from each other to release the battery cell from clamping, the battery cell will be placed back into the support groove 531. Finally, the third linear drive 510 will drive the driven member 520 and the support member 530 back to their initial positions to place the shaped battery cell on the conveyor belt, and then wait for the next battery cell to be lifted and shaped.
[0056] For example, the third linear drive 510 is a lifting cylinder.
[0057] In some specific embodiments, the feeding assembly 500 further includes a limiting assembly 540, which includes a limiting block 541 and a driven block 542. The limiting block 541 is disposed on the third linear drive member 510, and the driven block 542 is disposed on the driving end of the third linear drive member 510. The limiting block 541 is located on the moving path of the driven block 542.
[0058] Please continue reading. Figure 5 As shown, in order to prevent the driven member 520 and the support member 530 from colliding with other components due to excessive lifting height, it is necessary to limit the maximum stroke of the driven member 520. When the driven member 520 and the support member 530 are lifted to the maximum height, the driven block 542 will touch the limit block 541 to prevent the driven member 520 and the support member 530 from continuing to move upward, thereby limiting the maximum stroke of the driven member 520.
[0059] In some specific embodiments, an adjustment mounting groove 550 is provided through the follower 520.
[0060] Please continue reading. Figure 5As shown, in order to lift and feed battery cells of different lengths, an adjustment mounting groove 550 is provided in the driven member 520. By adjusting the installation position of the driven member 520 and the moving end of the third linear drive member 510, the position of the support member 530 is adjusted so that it can support battery cells of different lengths. In this embodiment, the adjustment mounting groove 550 is an elongated oval slot, which can be connected to the moving and fixed end of the third linear drive member 510 by bolt connection.
[0061] In some specific embodiments, the cell shaping device further includes an information acquisition component 600, which includes a mounting plate 610 and a collector 620. The collector 620 is disposed on the mounting plate 610, and the substrate 100 has a through-hole groove 110, which is located on the information acquisition path of the collector 620.
[0062] See Figure 1 As shown, in order to record each battery cell into the system, the QR code or barcode affixed to the battery cell is scanned by the collector 620, so that each battery cell can be traced.
[0063] For example, the data acquisition device 620 can be an industrial camera.
[0064] This application also provides a battery cell production equipment, which includes the battery cell shaping device of any of the above claims, and also includes a corresponding conveying device for conveying the battery cells. The conveying device can be a conveyor belt. Specifically, in order to enable the feeding assembly 500 to lift the battery cells, multiple spaced support blocks can be set on the conveyor belt, and support grooves adapted to the battery cells can be opened on the support blocks.
