[0002] The battery cell is the most basic component of a battery. It is usually an electrochemical device encapsulated in a metal casing, used to store and release electrical energy. The battery cell converts chemical energy into electrical energy through chemical reactions. It is mainly composed of a positive electrode, a negative electrode, a separator, and an electrolyte. The positive and negative electrodes are the two polar ends of the battery cell, separated by the separator. The electrolyte acts as an ion transport medium to maintain ion flow.

[0003] During the production and processing of battery cells, they need to be wound to facilitate further processing and use. However, common battery cell winding devices cannot flexibly adjust their size according to different winding diameters, which is inconvenient. When size adjustment is needed, it takes a lot of time, reducing the practicality of the device. Utility Model Content

[0024] This utility model provides the following technical solution:

[0025] Example 1

[0026] Combination Figures 1 to 4 A battery cell winding device includes a cylinder 1, an adjustment mechanism 2 is provided inside the cylinder 1, and a self-locking mechanism 3 is provided on the left side of the adjustment mechanism 2;

[0027] The adjusting mechanism 2 includes a threaded rod 21, which is rotatably connected to the inner wall of the cylinder 1. A support plate frame 22 is threadedly connected to the outer wall of the threaded rod 21. A cross block 23 is fixedly connected to the inner wall of the cylinder 1. A driving assembly 24 is provided on the outer wall of the threaded rod 21. A support shaft 25 is provided inside the driving assembly 24. A connecting plate 26 is fixedly connected to the left side of the cross block 23.

[0028] Furthermore, a rectangular opening is provided inside the support plate frame 22, and the support plate frame 22 is slidably connected to the outside of the cross block 23 through the rectangular opening, so that the support plate frame 22 can move stably.

[0029] Furthermore, the connecting plate 26 has a rotating hole inside, and the threaded rod 21 is rotatably connected to the inner wall of the rotating hole to provide stable support for the threaded rod 21.

[0030] Furthermore, a through hole is provided on the left side of the cylinder 1, and the support shaft 25 is rotatably connected to the inner wall of the through hole to provide stable support for the support shaft 25.

[0031] Furthermore, the drive assembly 24 includes a large bevel gear and four small bevel gears, and four threaded rods 21 are provided. The four threaded rods 21 are respectively fixedly connected to the inner rings of the four small bevel gears, and the support shaft 25 is fixedly connected to the inner ring of the large bevel gear. The large bevel gear and the four small bevel gears mesh with each other, thereby achieving the purpose of stable driving.

[0032] Example 2

[0033] See Figures 1 to 4 Furthermore, based on Embodiment 1, the self-locking mechanism 3 includes a support block 31, which is fixedly connected to the left side of the cylinder 1. A worm gear 32 is rotatably connected inside the support block 31, and a worm wheel 33 meshes with the outer wall of the worm gear 32 to achieve the purpose of driving self-locking and ensure the further development of adjustment work.

[0034] Furthermore, the worm gear 33 is fixedly connected to the outer wall of the support shaft 25, and a handwheel is fixedly connected to the top of the worm 32, so that the worm 32 can be rotated by shaking the handwheel.

[0035] In actual operation, when this device is used, if it is necessary to flexibly adjust the size of the battery cell winding according to different battery cell winding scenarios, the handwheel can be turned to drive the worm 32 to rotate. The worm 32 can drive the support shaft 25 to rotate through the transmission of the worm wheel 33, thereby achieving the purpose of driving, which facilitates further size adjustment. At the same time, the self-locking effect of the worm wheel 33 and the worm 32 can ensure the stability of the adjustment and prevent easy transmission of rotation, which facilitates the further development of the battery cell winding work.

[0036] When the support shaft 25 rotates, it drives the threaded rod 21 to rotate through the drive assembly 24. Since the threaded rod 21 and the support plate frame 22 are threadedly connected, and the support plate frame 22 can slide and limit on the outside of the cross block 23, the rotational motion of the threaded rod 21 is converted into the linear motion of the support plate frame 22, so that the four support plates frame 22 can move away from each other, thereby achieving the purpose of adjusting the winding diameter of the battery cell, improving the convenience of operation and use, and reducing the time required for size adjustment, thus enhancing the practicality of the device.
