Description

A novel anti-wrinkle device for cutting aluminum foil for lithium batteries Technical Field

[0001] This utility model relates to the field of lithium battery production, and more specifically, to a novel anti-wrinkle device for cutting aluminum foil for lithium batteries. Background Technology

[0002] Aluminum foil is a crucial electrode material in lithium-ion battery production. To meet the production needs of lithium-ion batteries of different specifications, large-sized aluminum foil typically needs to be slit into appropriate widths. However, existing aluminum foil slitting processes present several problems. Aluminum foil is thin and flexible, making it susceptible to wrinkles during slitting due to external forces. Wrinkles not only affect the appearance of the aluminum foil but also reduce the performance and safety of the lithium-ion battery, as wrinkles can lead to uneven distribution of electrode materials, impacting charge / discharge efficiency and cycle life. Therefore, developing a device that effectively prevents wrinkles during aluminum foil slitting while improving slitting quality and efficiency is of significant practical importance. Summary of the Invention

[0003] 1. Technical problems to be solved

[0004] To address the issue that existing aluminum foil is thin and flexible, making it susceptible to wrinkles during slitting due to external forces, which not only affects the appearance of the aluminum foil but also reduces the performance and safety of lithium batteries—as wrinkles can lead to uneven distribution of electrode materials, impacting charge / discharge efficiency and cycle life—this invention aims to provide a novel anti-wrinkle device for lithium battery aluminum foil slitting. This device utilizes a support device and a limiting guide roller to compress and support the aluminum foil strip. The design incorporates an elastic buffer layer on the surface of the support guide roller and anti-slip textures on the surface of the limiting guide roller. This effectively reduces friction, vibration, and misalignment of the aluminum foil during support, guidance, and slitting, increasing the tension of the aluminum foil strip and significantly reducing the likelihood of wrinkles, thus improving the quality of aluminum foil slitting. The support device features a sliding connection between the moving rod and the fixed block, and a pull ring is fixedly connected to the top of the limiting plate, facilitating manual adjustment of the extrusion guide roller's position to accommodate aluminum foil strips of different thicknesses and materials.

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

[0024] Example 1:

[0025] Please refer to Figures 1-3. This utility model provides a technical solution: a novel lithium battery aluminum foil slitting and anti-wrinkle device, including a workbench 1, mounting plates 2 fixedly connected to both sides of the workbench 1, a support frame 3 fixedly connected to the top of the mounting plates 2, a support guide roller 4 installed on the support frame 3, and multiple support guide rollers 4 cooperating to support and guide the aluminum foil strip 5, a fixing frame 6 fixedly connected to the top of the middle of the workbench 1, a top cover 7 fixedly connected to the top of the fixing frame 6, a connecting frame 8 fixedly connected to the bottom of one side of the top cover 7, a support device 9 provided at the end of the connecting frame 8, a groove provided on the surface of the workbench 1, and limiting guide rollers 10 provided at both ends of the groove of the workbench 1, the support device 9 cooperating with the limiting guide rollers 10 to squeeze and support the aluminum foil strip 5, and an electric telescopic rod 11 fixedly connected to the bottom of the other side of the top cover 7, with a cutting roller 12 provided at the output end of the electric telescopic rod 11. The aluminum foil strips 5 to be cut are sequentially passed through the support guide rollers 4, positioning them between the support device 9 and the limiting guide roller 10. The position of the extrusion guide roller 94 is adjusted by manually pulling the pull ring 97, ensuring that the extrusion guide roller 94 and the limiting guide roller 10 provide appropriate extrusion support for the aluminum foil strips 5. Then, the cutting operation begins: the electric telescopic rod 11 is activated, and its output end drives the cutting roller 12 downwards, causing the annular blade 15 on the surface of the cutting roller 12 to cut the aluminum foil strips 5. During the cutting process, the support guide rollers 4 and the limiting guide roller 10 provide stable support and guidance for the aluminum foil strips 5, preventing wrinkles and deviations. This effectively reduces friction, vibration, and deviation during the support, guidance, and cutting processes, increases the tension of the aluminum foil strips, and thus significantly reduces the possibility of wrinkles, improving the quality of aluminum foil cutting.

[0026] The support device 9 includes a fixed block 91, a spring 92, a pressing block 93, a pressing guide roller 94, a moving rod 95, and a limiting plate 96. The fixed block 91 is fixedly connected to the connecting frame 8. The bottom of the fixed block 91 is fixedly connected to the spring 92. The bottom of the spring 92 is fixedly connected to the pressing block 93. The bottom of the pressing block 93 is provided with the pressing guide roller 94, which presses and supports the aluminum foil strip 5. The top of the pressing block 93 is fixedly connected to the moving rod 95. The moving rod 95 is sleeved with the spring 92 and slidably connected to the fixed block 91. The top of the moving rod 95 is fixedly connected to the limiting plate 96. A support device 9 is provided, and a fixed block 91 supports the extrusion block 93 through a spring 92, which drives the extrusion block 93 to move downward, and drives the extrusion guide roller 94 to move downward. The extrusion guide roller 94 cooperates with the limiting guide roller 10 to support the aluminum foil strip, which effectively reduces the friction, vibration and offset of the aluminum foil during the support, guidance and cutting process, increases the tension of the aluminum foil strip, and thus greatly reduces the possibility of wrinkles in the aluminum foil and improves the quality of aluminum foil cutting.

[0027] A pull ring 97 is fixedly connected to the top of the limiting plate 96. The pull ring 97 is provided to facilitate the adjustment of the position of the support device 9 by the staff.

[0028] There are two moving rods 95. This improves the support stability of the extrusion guide roller 94.

[0029] The surface of the support guide roller 4 is covered with an elastic buffer layer to reduce the friction and vibration between the aluminum foil strip 5 and the support guide roller 4 during the support and guidance process, and to further prevent the aluminum foil strip 5 from wrinkling.

[0030] The surface of the limiting guide roller 10 is provided with anti-slip texture, which can increase the friction between the aluminum foil strip 5 and the limiting guide roller 10 and prevent the aluminum foil strip 5 from shifting during the cutting process.

[0031] The cutting roller 12 has multiple annular blades on its surface, which facilitates the cutting of aluminum foil strips.
