[0002] Lithium-ion batteries are becoming increasingly widespread, but they have also encountered many problems during use. For example, batteries can deform after a period of use, affecting device performance and reducing the battery's lifespan. The winding of the battery cells is one of the reasons why batteries are prone to deformation.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: existing lithium-ion cell winding devices cannot effectively clean the materials before winding, which affects the product quality after the cells are wound. In addition, after winding one cell, it needs to be disassembled before the next cell can be wound, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to address the problems in the prior art where it is impossible to clean the material before winding and it is impossible to wind the battery cell continuously, and to propose a lithium-ion battery cell winding device.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] 1. By setting up a clamping cleaning mechanism, the motor drives the adhesive cylinder to rotate, thereby cleaning both the top and bottom surfaces of the material to be wound simultaneously. The adhesive cylinder and the winding plate are clamped at the same time to ensure that the material to be wound is always in a taut state. This can effectively remove surface dust and impurities, improve the cleanliness of the battery cell, reduce the performance degradation or failure of the battery cell caused by contaminants, and improve the safety and reliability of the battery cell. The taut state can make the materials of each layer inside the battery cell fit tightly together, reduce the gap between layers, improve the structural stability of the battery cell, and avoid the instability of the internal structure of the battery cell, which would affect the performance and life of the battery cell.

[0021] 2. Through the winding mechanism, motor three drives the battery cells to perform winding, while motor two moves the wound battery cells and moves the unwound battery cells to the working position. This reduces equipment downtime and waiting time, enabling continuous production, greatly improving production efficiency, making full use of the winding device, and reducing equipment idle time.

[0028] Example 1

[0029] like Figures 1-3 As shown, the present invention proposes a lithium-ion battery cell winding device, including a base plate 1, a pressing and cleaning mechanism, a winding mechanism, and a dust collection box 209.

[0030] The pressing and cleaning mechanism is located on the top of the base plate 1 and is used to press the material to be wound and clean both ends of the material.

[0033] The clamping cleaning mechanism includes a mounting frame 201, a motor 202, an adhesive cartridge 203, a rotating shaft 204, and a switch assembly. The mounting frame 201 is located on the top of the base plate 1, the motor 202 is located on the side of the mounting frame 201, the rotating shaft 204 is located at the output end of the motor 202, the adhesive cartridge 203 is located outside the motor 202, a straight slide rail 206 is located inside the mounting frame 201, and a sliding block 205 is slidably mounted on the straight slide rail 206.

The switch assembly includes a rotating door 211, a pull ring 212, and a locking block 213. The rotating door 211 is rotatably located on the side of the dust collection box 209 away from the adhesive tube 203. The pull ring 212 is located on the side of the rotating door 211.

[0034] Example 2

[0035] like Figures 4-5 As shown, this utility model proposes a lithium-ion battery cell winding device. Compared with Embodiment 1, this embodiment details the structure of the winding mechanism.

[0036] The winding mechanism includes a support column 311, a second motor 301, a second rotating shaft 302, a rotating frame 303, and mounting components. The support column 311 is located on the side of the base plate 1, the second motor 301 is located on the side of the support column 311, the second rotating shaft 302 is located at the output end of the second motor 301, the rotating frame 303 is located on the outer side of the second rotating shaft 302, and a third rotating shaft 304 is rotatably mounted on the end of the rotating frame 303 away from the second rotating shaft 302. There are two symmetrically arranged third rotating shafts 304 about the rotating frame 303. A third motor 312 is mounted on the end of the third rotating shaft 304. The starting time of the second motor 301 and the third motor 312 is set by computer. During the winding operation, the third motor 312 rotates continuously. After the winding is completed, the second motor 301 rotates half a turn, thereby driving the third motor 312 on the left to rotate to the right. At this time, the third motor 312 stops working, and the third motor 312 on the left starts to start the winding operation. The mounting assembly includes a mounting plate 305, a fixing plate 307, a telescopic tube 308, and a winding plate 306. The mounting plate 305 is located at the end of the rotating shaft 304 away from the motor 312. The fixing plate 307 is located at the end of the mounting plate 305. There are two fixing plates 307 symmetrically arranged about the mounting plate 305. The telescopic tube 308 is located on the side of the fixing plate 307. A spring 309 is provided on the outside of the telescopic tube 308. A clamping plate 310 is provided at the end of the telescopic tube 308 away from the fixing plate 307. The winding plate 306 is provided on the side of the clamping plate 310. The upper and lower ends of the clamping plate 310 are both set as arc surfaces to facilitate the installation of the winding plate 306 between the two clamping plates 310.

[0037] In summary, when using this utility model, the material to be wound is passed between the two adhesive cylinders 203. Then, according to the thickness of the material, the rotating rod 208 is rotated. The rotating rod 208 drives the threaded rod 207 to rotate. When the threaded rod 207 rotates, it drives the sliding block 205 to move on the straight slide rail 206, thereby adjusting the distance between the two adhesive cylinders 203 so that they are close to the material to be wound. The end of the material to be wound is attached to the outside of the winding plate 306. Then, motors 202, 301, and 312 are started. Motor 312 drives the winding plate 306 to rotate through the rotating shaft 304, thereby winding the material to be wound. During this process, motor 202 drives the adhesive cylinders 203 through the rotating shaft 204. When the roller 203 rotates, the dust on the outside of the knitted fabric adheres to it when it comes into contact with the fabric and is scraped into the dust collection box 209 as it passes through the dust collection box 209, thus collecting the dust and impurities and ensuring that the material to be wound is clean and tidy. After winding is completed, the motor 301 and the cutter 5 are started. The cutter 5 cuts the material to be wound. The motor 301 rotates half a turn to adjust the position of the winding plate 306, so that the other winding plate 306 can start working. The wound plate 306 is removed and a new one is installed for the next winding operation. After a lot of dust and impurities are collected in the dust collection box 209, the rotating door 211 is opened by the pull ring 212 to clean out the dust inside.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
