The sway adjustment roller mechanism can be fixedly connected to the winding equipment through the mounting base 1. The lower end of the micro-head assembly 2 is connected to one end of the adjustment plate 3, and the micro-head assembly 2 is used to drive the adjustment plate 3 to adjust the sway angle. Through the precise adjustment function of the micro-head assembly 2, the sway angle of the adjustment plate 3 can be finely adjusted. The roller assembly 4 is connected to the lower end of the adjustment plate 3. The roller assembly 4 is used to support and guide the electrode sheet, and then adjust the sway angle of the roller through the adjustment plate 3, thereby correcting the belt deviation and returning the belt to normal, effectively solving the problem of wavy edges on the incoming electrode sheet, and improving the quality of the bare battery cell.

[0025] Reference Figure 3 In an embodiment of this utility model, the mounting base 1 includes a fixing plate 11, a mounting plate 12, and a reinforcing plate 13. The fixing plate 11 is fixedly connected to the base plate of the winding equipment. The fixing plate 11 is vertically connected to one end of the mounting plate 12, so that the adjusting plate 3 and the roller assembly 4 connected to the mounting plate 12 are in a suspended state, which facilitates the micro-head assembly 2 to adjust the sway of the adjusting plate 3 and the roller assembly 4, and also facilitates the smooth feeding of the electrode sheet. The reinforcing plate 13 is connected at the connection between the fixing plate 11 and the mounting plate 12, and adopts a composite structure, which effectively enhances the overall rigidity and stability of the mounting base 1. The other end of the mounting plate 12 is provided with a notch 121, which is specifically used to accommodate and install the micro-head assembly 2. Setting the micro-head assembly 2 at the notch 121 not only facilitates the precise positioning and installation of the micro-head assembly 2, but also effectively avoids interference with other components, and improves the compactness and operating efficiency of the mechanism.

[0026] Reference Figure 3 In an embodiment of this utility model, the micro-head assembly 2 includes a micro-head 21, a connector 22, a fixing ring 23, and a support plate 24. One end of the connector 22 is connected to the mounting plate 12, and the micro-head 21 is fixed through and fixed to the other end of the connector 22. The lower end of the micro-head 21 is connected to the fixing ring 23, and the fixing ring 23 is engaged with the upper end of the support plate 24. The lower end of the support plate 24 is fixedly connected to the adjustment plate 3, so that the adjustment plate 3 is connected to the mounting plate 12 through the micro-head assembly 2. At the same time, the height of one end of the adjustment plate 3 can be adjusted by rotating the micro-head 21, thereby adjusting the sway angle of the roller assembly 4 to bring the deviated electrode belt back to the normal state, effectively improving the yield of bare cells.

[0027] Specifically, the connector 22 is configured with a right-angle structure. One end of the connector 22 is provided with a first stepped screw 221, which passes through the connector 22 and is fixed to the mounting plate 12. The other end of the connector 22 is located above the notch 121 and is provided with a fixing through hole 222. The micrometer head 21 is fixedly installed in the fixing through hole 222, thereby fixing the micrometer head 21, enabling the micrometer head 21 to work normally, and ensuring the firmness of the installation of the micrometer head 21.

[0028] Specifically, the lower end of the fixed ring 23 is provided with a connection limit 231, which plays a key role in positioning and connection. At the same time, the upper end of the support plate 24 extends vertically with a connecting plate 241. The connecting plate 241 is provided with a snap-fit ​​groove 242. The connection limit 231 is set in the snap-fit ​​groove 242.

In addition, the lower end of the support plate 24 is provided with a second step screw 243. The second step screw 243 passes through the support plate 24 and is fixedly connected to the adjustment plate 3, so that the micrometer head assembly 2 is connected to the adjustment plate 3. By rotating the micrometer head 21, the sway angle of the adjustment plate 3 can be adjusted, thereby adjusting the sway angle of the roller.

[0029] Specifically, one end of the adjustment plate 3 is provided with a fixing hole 31 and a third-step screw 32. The third-step screw 32 passes through the fixing hole 31 and is connected to the mounting plate 12. The other end of the adjustment plate 3 is provided with an arc-shaped waist hole 33 and a fourth-step screw 34. The fourth-step screw 34 passes through the arc-shaped waist hole 33 and is connected to the mounting plate 12. The dual-point fixing design enhances the stability of the adjustment plate 3. At the same time, the design of the arc-shaped waist hole 33 allows the adjustment plate 3 to be tilted within a certain range under the drive of the micrometer head assembly 2. The fourth-step screw 34 is used to lock the adjustment plate 3 to fix the angle, so as to achieve precise adjustment of the tilt angle of the adjustment plate 3.

The indicator arrow 5 is aligned with the scale line 6. In practical applications, multiple sway adjustment roller mechanisms of this utility model are installed in the lithium battery winding equipment. When adjusting the rollers, the indicator arrow 5 will float up and down on the scale line 6 with the adjustment angle. This allows the approximate position of each sway adjustment roller mechanism to be clearly seen, ensuring that the direction of the sway adjustment angle is consistent, so as to avoid the electrode sheet from running off-center.

[0031] Reference Figure 3 In an embodiment of this utility model, the lower end of the adjustment plate 3 is connected to a connecting block 35, and the connecting block 35 is provided with mounting holes. The roller assembly 4 is fixedly connected to the connecting block 35 by fixing screws to securely install the roller assembly 4.

[0032] Specifically, the roller assembly 4 includes a roller 41, a roller mounting plate 42, and a mounting side plate 43. The roller 41 is equipped with an adjusting roller shaft, and bearings are installed at both ends of the roller 41 so that the roller 41 rotates on the adjusting roller shaft. The two ends of the adjusting roller shaft are fixedly connected to the mounting side plate 43. The mounting side plate 43 is connected to both ends of the roller mounting plate 42. The roller mounting plate 42 is fixedly connected to the connecting block 35 to stably install the roller assembly 4 and ensure that the roller 41 can rotate freely, thereby smoothly transmitting the electrode sheets.

[0033] This utility model also discloses a lithium battery winding device for winding electrode sheets, including a substrate and several yaw adjustment roller mechanisms as described in any one of the above. The several yaw adjustment roller mechanisms are evenly spaced on the substrate, and the electrode sheets travel on the several yaw adjustment roller mechanisms. At the same time, each yaw adjustment roller mechanism includes key components such as a micro-head assembly 2, an adjustment plate 3, and a roller assembly 4. These components work together to achieve fine adjustment of the electrode sheet transmission path, ensuring stable transmission and precise winding of the electrode sheets, and effectively improving the quality of the bare battery cells.
