Description

Technical Field

[0001] This utility model relates to the field of negative electrode winding, specifically a negative electrode winding changing buffer device. Background Technology

[0002] Negative electrode rolls are one of the essential core raw materials in the lithium-ion battery winding process. They are roll-shaped negative electrode materials produced through processes such as coating, drying, rolling, and slitting, and are used to be wound together with positive electrode rolls and separator rolls on a winding machine to form the battery cell (core). Their quality directly affects key performance characteristics of the battery, such as safety, capacity, internal resistance, and cycle life.

[0003] During the rewinding process of negative electrode rolls, in order to ensure that the negative electrode rolls are tightly wound, a tensioning mechanism is often required to tension the wound negative electrode rolls. This requires a buffer device to cushion and protect the negative electrode rolls. However, current buffering equipment uses a motor-driven screw to move the buffer rollers, which cannot achieve an elastic connection between the buffer rollers, thus failing to protect the buffered negative electrode rolls. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A storage groove is formed inside the support base, with both ends of the storage groove connected to a moving plate via guide components. A rack plate is installed at the inner end of the moving plate. A moving drive component for driving the rack plate is located at the center of the storage groove. A side wall support plate is fixedly installed at the outer end of the moving plate.

A second motor is installed on the side wall of the side wall support plate, and the motor shaft of the second motor is connected to the second rotating shaft. Several sets of vertical plates are symmetrically arranged in two pairs at the front and rear of the top of the support base. A sliding recess is formed at the center of each vertical plate, with sliding connectors at both ends inside the sliding recess. A buffer roller is arranged between the sliding connectors at the front and rear ends, which are horizontally aligned. The sliding connectors located outside the vertical plates are interconnected via elastic connecting components.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1-3 In this embodiment of the present invention, a negative electrode winding change buffer device includes a support base 1. Rolling components are provided at the four corners of the bottom of the support base 1 to facilitate adaptive movement and orientation adjustment. A storage groove 5 is provided inside the support base 1. Both ends of the storage groove 5 are connected to a moving plate 6 via guide components. A rack plate 10 is installed at the inner end of the moving plate 6. A moving drive component for driving the rack plate 10 to move is provided at the center of the storage groove 5. A side wall support plate 14 is fixedly provided at the outer end of the moving plate 6. A mounting bracket is provided at the top of the side wall support plate 14. The mounting recess 15 is connected to the take-up roller 17 via a second rotating shaft 16. A second motor 18 is mounted on the side wall of the side wall support plate 14, and the motor shaft of the second motor 18 is connected to the second rotating shaft 16. Several sets of vertical plates 19 are symmetrically arranged in two pairs at the top of the support base 1. A sliding recess 20 is opened at the center of the vertical plate 19. Sliding connectors 21 are provided at both ends inside the sliding recess 20. A buffer roller 22 is provided between the sliding connectors 21 at the same level at both ends. The sliding connectors 21 located on the outside of the vertical plate 19 are connected to each other through an elastic connecting component.

[0022] This utility model drives the second motor 18 to drive the second rotating shaft 16 to rotate. The second rotating shaft 16 drives the take-up roller 17 to rotate. The take-up roller 17 drives the negative electrode roll to change rolls. During the change-up process, the rack plate 10 is driven to move by the moving drive component. The rack plate 10 drives the moving plate 6 to move synchronously under the guidance of the guide component. The moving plate 6 drives the side wall support plate 14 to move synchronously. The side wall support plate 14 drives the connected take-up roller 17 to perform tensioning. The negative electrode roll is wound in a serpentine manner on the buffer roller 22. The elastic connection component can buffer the negative electrode roll wound on the buffer roller 22, thereby facilitating the change-up of the negative electrode roll.

[0023] See Figure 1In one embodiment of this utility model, the rolling assembly includes a support leg 2 fixedly connected to the bottom of the support base 1. A roller 3 is provided at the bottom of the support leg 2, and a brake 4 is provided at the outer end of the roller 3. The arrangement of the roller 3 and the brake 4 can facilitate the appropriate movement and orientation adjustment of the device.

[0024] See Figure 3 In one embodiment of this utility model, the guiding component includes a guiding groove 9 formed on the inner sidewalls of the front and rear ends of the storage groove 5. The outer end of the moving plate 6 is connected to the guiding plate 8 through a connecting plate 7. The guiding plate 8 is disposed inside the guiding groove 9. During the movement of the moving plate 6, the moving plate 6 drives the guiding plate 8 to move in a directional manner under the guidance of the guiding groove 9 through the connecting plate 7, thereby facilitating the smooth movement of the moving plate 6.

[0025] See Figure 3 In one embodiment of this utility model, the moving drive assembly includes a first motor 11 fixedly connected to the center of the bottom of the support base 1. A first rotating shaft 12 is mounted on the motor shaft of the first motor 11, and a drive gear 13 is mounted on the first rotating shaft 12. The drive gear 13 is meshed with the rack plate 10. When the first motor 11 works, the first motor 11 drives the first rotating shaft 12 to rotate, and the first rotating shaft 12 drives the meshed drive gear 13 to rotate. The drive gear 13 drives the meshed rack plate 10 to perform movement orientation adjustment.

[0026] See Figure 1 In one embodiment of the present invention, the elastic connection component includes a connecting sleeve 23 connected to the sliding connector 21. A buffer spring 24 is provided between the connecting sleeves 23. The buffer spring 24 can realize the elastic connection between the connecting sleeves 23. In this way, the buffer rollers 22 at both ends are elastically buffered during the rewinding process of the negative electrode roll.

[0027] Working Principle: This invention involves serpentinely winding the negative electrode roll onto the buffer roller 22, with its end connected to the take-up roller 17. A second motor 18 drives a second rotating shaft 16 to rotate the take-up roller 17, enabling the rewinding of the negative electrode roll. During this rewinding process, a first motor 11 drives a first rotating shaft 12, which in turn drives a drive gear 13. The drive gear 13 then moves a meshing rack plate 10. Simultaneously, the rack plate 10 moves a moving plate 6 horizontally under the guidance of a guide assembly. The moving plate 6 also moves a sidewall support plate 14, which in turn tensions the take-up rollers 17 at both ends. The take-up rollers 17 then simultaneously tension the negative electrode roll. During tensioning, the negative electrode roll wound on the buffer roller 22 compresses the buffer roller 22, causing it to move inwards. The buffer spring 24 is compressed, generating elasticity, thus buffering the negative electrode roll and facilitating its rewinding.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
