Description
Technical Field
[0001] This utility model relates to the field of new energy battery manufacturing equipment technology, and in particular to an electrode foil winding anti-wrinkle mechanism. Background Technology
[0002] In the field of new energy battery manufacturing, electrode foil is an important component of the battery cell, and its winding process directly affects the quality of subsequent electrode cutting, stacking, or winding. Electrode foil is usually thin and wide, and during high-speed winding, it is prone to wrinkling due to uneven tension, edge misalignment, or surface unevenness. Once wrinkles occur, they not only affect the tightness and flatness of the roll, but may also lead to unstable electrochemical performance of the electrode during use, and in severe cases, even affect the safety of the battery.
[0003] In existing technologies, some tensioning devices rely on fixed pressure rollers for loading, which cannot effectively adjust according to the dynamic tension changes of the electrode foil, resulting in uneven tension during winding and wrinkling of the electrode foil. Existing flattening structures mostly use single-roller pressing, where the electrode foil is only stressed at a single point, making it difficult to achieve uniform pressure and flattening, and easily leading to insufficient pressing in local areas and ripples. Some devices lack guidance and anti-deviation design for the electrode foil edges, making the electrode foil prone to deviation during operation, further aggravating wrinkling and unbalanced winding problems. The lack of effective limiting and uniform pressing measures in the early stages of winding results in uneven first-layer winding, which in turn affects the regularity of the subsequent overall roll material, making it impractical. Therefore, this utility model discloses an anti-wrinkle electrode foil winding mechanism to solve the problems of uneven tension adjustment and insufficient flattening effect in existing technologies. Summary of the Invention

A drive belt is sleeved on the driven wheel, and a drive wheel is installed at one end of the output shaft of the servo motor, and the other end of the drive belt is sleeved on the drive wheel.
[0007] Preferably, the tension adjustment assembly includes a first mounting groove, which is respectively opened on the upper sidewall of the two sets of second mounting frames.

A first spring is sleeved on the first guide rod. A tension adjustment roller is rotatably mounted on the tension adjustment shaft between the two sets of second mounting frames through a double-row angular contact ball bearing. The lower arc wall surface of the tension adjustment roller is in contact with the outer wall surface of the electrode foil.
[0008] Preferably, a first circular hole is provided on the tension adjusting shaft corresponding to the position of the first guide rod, and the diameter of the first circular hole is the same as the diameter of the first guide rod, and a sliding coating is provided on the contact surface between the first guide rod and the first circular hole.
[0009] Preferably, one end of the first spring is fixedly installed on the upper inner wall of the first mounting groove, and the other end of the first spring is fixedly installed on the upper arc wall of the tension adjusting shaft.
[0010] Preferably, the pressure equalization assembly includes a second mounting groove, which is respectively opened on the upper sidewall of the two sets of the third mounting brackets. The upper and lower sidewalls of the second mounting groove are jointly equipped with a second guide rod. A first pressure equalization shaft and a second pressure equalization shaft are slidably sleeved on the two sets of the second guide rods. Multiple sets of anti-wrinkle pressure equalization rollers are rotatably mounted on the first pressure equalization shaft and the second pressure equalization shaft between the two sets of the third mounting brackets through double-row angular contact ball bearings. The electrode foil passes through the arc wall surface between the multiple sets of anti-wrinkle pressure equalization rollers. A second spring is sleeved on the second guide rod above the first pressure equalization shaft, and a third spring is sleeved on the second guide rod below the second pressure equalization shaft.
[0011] Preferably, a second circular hole is provided on the first equalizing shaft at the position corresponding to the second guide rod, and the diameter of the second circular hole is the same as the diameter of the second guide rod.

[0014] The beneficial effects of this utility model are: By rationally arranging the winding drive section, tension adjustment component, and pressure equalization component on a rectangular frame, multiple anti-wrinkle effects can be achieved during the electrode foil winding process, exhibiting significant technical advantages. The tension adjustment component, utilizing the cooperation of a first guide rod, a first spring, and a tension adjusting roller, enables the electrode foil to automatically compensate for tension changes during operation, thereby ensuring it remains under tension throughout the winding process and avoiding the uneven tension problem caused by the inability to dynamically adjust traditional fixed pressure rollers. The pressure equalization component arranges multiple sets of anti-wrinkle pressure equalization rollers between the upper and lower pressure equalization shafts, each elastically loaded by a second and third spring. This design ensures uniform pressure on the electrode foil across its entire width, effectively flattening the material surface and preventing localized ripples caused by single-point compression. It also improves the overall flatness and density of the roll. Anti-deviation rings at both ends of the take-up roller physically limit the edges during electrode foil winding, preventing deviation and ensuring neat edges. Guide rollers straighten the electrode foil before it enters the winding path, preventing wrinkles caused by unstable feeding posture. The winding drive uses a combination of a servo motor and belt drive, ensuring stability of the take-up shaft and uniform winding speed. Through the synergistic effect of these multiple structures, this invention not only achieves uniform electrode foil tension, surface flattening, and smooth winding throughout the entire winding process, but also effectively suppresses edge deviation and uneven initial winding, significantly improving winding quality, reducing scrap rate, and enhancing the processing adaptability and product consistency of the electrode foil in subsequent processes. It has high practical value and significant potential for wider application. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0020] This utility model provides, for example Figures 1 to 5An electrode foil winding anti-wrinkle mechanism is shown, comprising: a rectangular frame 1, with first mounting brackets 2 at each of the four corners of the upper end face of the rectangular frame 1, second mounting brackets 3 on both sides of the upper end face of the rectangular frame 1, and third mounting brackets 4 on both sides near the middle of the upper end face of the rectangular frame 1. An electrode foil 11 is placed directly above the rectangular frame 1, and a servo motor 5 is mounted on one side wall of the rectangular frame 1. A winding shaft 9 is rotatably mounted on the side walls of the two sets of first mounting brackets 2 on the same side, and a winding roller 15 is mounted on the winding shaft 9 between the two sets of first mounting brackets 2. Anti-deviation rings 10 are respectively mounted at both ends of the winding roller 15. At the other end, the inner walls of the two sets of first mounting frames 2 are rotatably mounted with guide rollers 12. The electrode foil 11 passes through the outer arc wall of the guide roller 12. One end of the winding shaft 9 passes through and protrudes from the outer wall of the first mounting frame 2, and the end of the winding shaft 9 is mounted with a driven wheel 8. A drive belt 7 is sleeved on the driven wheel 8. One end of the output shaft of the servo motor 5 is mounted with a drive wheel 6, and the other end of the drive belt 7 is sleeved on the drive wheel 6. The two sets of second mounting frames 3 are equipped with tension adjustment components, which are used to adjust the tension of the electrode foil 11. The two sets of third mounting frames 4 are equipped with pressure equalization components, which are used to flatten the electrode foil 11. By rationally arranging the winding drive section, tension adjustment component, and pressure equalization component on the rectangular frame 1, multiple anti-wrinkle effects can be achieved during the electrode foil winding process, which has significant technical advantages. The tension adjustment component utilizes the cooperation of the first guide rod 18, the first spring 19, and the tension adjustment roller 14 to enable the electrode foil to automatically compensate for tension changes during operation, thereby ensuring that it is always in a tensioned state during the winding process and avoiding the problem of uneven tension caused by the inability to dynamically adjust the traditional fixed pressure roller. The pressure equalization component arranges multiple sets of anti-wrinkle pressure equalization rollers 13 between the upper and lower pressure equalization shafts, and elastically applies them through the second spring 23 and the third spring 24 respectively. The load ensures uniform pressure on the electrode foil across its entire width, effectively flattening the material surface and preventing localized ripples caused by single-point pressing. This also improves the overall flatness and density of the roll. Anti-deviation rings 10 at both ends of the take-up roller 15 physically limit the edges during electrode foil winding, preventing deviation and ensuring neat edges. The guide roller 12 guides and straightens the electrode foil before it enters the winding path, preventing wrinkles caused by unstable feeding posture. The winding drive uses a combination of a servo motor 5 and belt drive, ensuring the stability of the take-up shaft 9 and the uniformity of winding speed. Through the synergistic effect of these multiple structures, this invention not only achieves uniform electrode foil tension, surface flattening, and smooth winding throughout the entire winding process, but also effectively suppresses edge deviation and uneven initial winding, thus significantly improving winding quality, reducing scrap rate, and enhancing the processing adaptability and product consistency of the electrode foil in subsequent processes. It has high practical value and significant potential for wider application.
[0021] Furthermore, in this example, such as Figure 1 and Figure 5 As shown, the tension adjustment assembly includes a first mounting groove 17, which is respectively opened on the upper side wall of two sets of second mounting frames 3. A set of first guide rods 18 are installed on the upper and lower side walls of the first mounting groove 17. Tension adjustment shafts 16 are slidably sleeved on the two sets of first guide rods 18. A first spring 19 is sleeved on the first guide rod 18. A tension adjustment roller 14 is rotatably installed on the tension adjustment shaft 16 between the two sets of second mounting frames 3 through a double-row angular contact ball bearing. The lower arc wall surface of the tension adjustment roller 14 is in contact with the outer wall surface of the electrode foil 11. A first circular hole is opened on the tension adjustment shaft 16 corresponding to the position of the first guide rod 18. The diameter of the first circular hole is the same as the diameter of the first guide rod 18. The contact surface between the first guide rod 18 and the first circular hole is provided with a sliding coating. One end of the first spring 19 is fixedly installed on the upper inner wall of the first mounting groove 17, and the other end of the first spring 19 is fixedly installed on the upper arc wall surface of the tension adjustment shaft 16. The first guide rod 18 is vertically fixed to the upper and lower end sidewalls of the first mounting groove 17 of the two sets of second mounting brackets 3. The end of the tension adjusting shaft 16 is slidably fitted on the first guide rod 18. The tension adjusting shaft 16 has a first circular hole in its shaft body, which matches the diameter of the first guide rod 18 and has a sliding coating on the contact surface, thereby achieving low-friction linear sliding of the tension adjusting shaft 16 on the first guide rod 18 without deflection. The tension adjusting shaft 16 is rotatably supported between the two sets of second mounting brackets 3 by a double-row angular contact ball bearing. The tension adjusting roller 14 is fixed on the tension adjusting shaft 16 and can rotate with the shaft. The lower arc wall surface of the tension adjusting roller 14 contacts the outer wall surface of the passing electrode foil 11. The first spring 19 is sleeved on the first guide rod 18, with one end fixed to the upper inner wall of the first mounting groove 17 and the other end fixed to the upper arc wall surface of the tension adjusting shaft 16, thereby applying a downward elastic preload to the tension adjusting shaft 16 (that is, the initial loading force of the tension adjusting roller 14 towards the electrode foil 11). During the winding process, the electrode foil 11 is introduced into the winding area by the guide roller 12 and pulled by the winding shaft 9. The tension of the electrode foil 11 changes dynamically with the winding speed, feeding, and drum diameter. The tension adjusting roller 14 contacts the electrode foil 11 under the preload of the first spring 19, forming a stable contact surface to monitor and respond to changes in the foil tension: when the tension of the electrode foil 11 decreases and shows a loosening trend, the first spring 19 drives the tension adjusting shaft 16 to continue pressing the tension adjusting roller 14 against the electrode foil 11 surface, maintaining contact and compensating for looseness, thereby preventing the electrode foil 11 from sagging or wrinkling locally; when the tension of the electrode foil 11 increases, the electrode foil 11 applies an upward force to the tension adjusting roller 14, causing the tension adjusting shaft 16 to slide upward along the first guide rod 18, compressing or releasing the first spring 19, thereby reducing the pressure on the electrode foil 11 and absorbing instantaneous tension peaks, avoiding tearing or forced local deformation due to excessive tightness. The sliding fit between the tension adjusting shaft 16 and the first guide rod 18, as well as the sliding coating, ensures the smoothness of axial displacement and positioning accuracy. The sliding coating is made of materials such as polytetrafluoroethylene. The double-row angular contact ball bearing ensures the rotational accuracy of the tension adjusting roller 14 during movement and its ability to withstand axial / radial loads.
[0022] Furthermore, in this example, such as Figure 2 and Figure 4As shown, the equalizing assembly includes a second mounting groove 21, which is respectively opened on the upper sidewall of two sets of third mounting brackets 4. A second guide rod 22 is mounted on both the upper and lower sidewalls of the second mounting groove 21. A first equalizing shaft 20 and a second equalizing shaft 25 are slidably sleeved on the two sets of second guide rods 22. Multiple sets of anti-wrinkle equalizing rollers 13 are rotatably mounted on the first equalizing shaft 20 and the second equalizing shaft 25 between the two sets of third mounting brackets 4 via double-row angular contact ball bearings. The electrode foil 11 passes through the arc-shaped wall surface between the multiple sets of anti-wrinkle equalizing rollers 13. A second spring 23 is sleeved on the second guide rod 22 above the first equalizing shaft 20 and a second guide rod 25 below the second equalizing shaft 25. A third spring 24 is sleeved and installed on the guide rod 22. A second circular hole is opened on the first equalizing shaft 20 at the position corresponding to the second guide rod 22. The diameter of the second circular hole is the same as the diameter of the second guide rod 22. A third circular hole is opened on the second equalizing shaft 25 at the position corresponding to the second guide rod 22. The diameter of the third circular hole is the same as the diameter of the second equalizing shaft 25. One end of the second spring 23 is fixedly installed on the upper inner wall of the second mounting groove 21, and the other end of the second spring 23 is fixedly installed on the upper arc wall of the first equalizing shaft 20. One end of the third spring 24 is fixedly installed on the lower inner wall of the second mounting groove 21, and the other end of the third spring 24 is fixedly installed on the lower arc wall of the second equalizing shaft 25. The second guide rod 22 is vertically fixed to the upper and lower end sidewalls of the second mounting groove 21 of the two sets of third mounting brackets 4. The ends of the first equalizing shaft 20 and the second equalizing shaft 25 are slidably engaged on the second guide rod 22 respectively. A second circular hole is opened at the position of the first equalizing shaft 20 corresponding to the second guide rod 22, and a third circular hole is opened at the position of the second equalizing shaft 25 corresponding to the second guide rod 22. The circular holes have the same diameter as the guide rods and are provided with a sliding coating on the contact surface to ensure that the first equalizing shaft 20 and the second equalizing shaft 25 have controlled linear displacement along the direction of the guide rods and do not tilt. Multiple sets of paired anti-wrinkle equalizing rollers 13 are rotatably assembled between the first equalizing shaft 20 and the second equalizing shaft 25 through a double-row angular contact ball bearing. The anti-wrinkle equalizing rollers 13 can rotate independently on the shaft but form a pair of rollers with the shaft as the reference. The electrode foil 11 passes between the roller gap of the first equalizing shaft 20 and the second equalizing shaft 25. The second spring 23 is sleeved on the second guide rod 22 located above the first equalizing shaft 20, with one end fixed to the inner wall of the second mounting groove 21 and the other end fixed to the upper arc wall of the first equalizing shaft 20; the third spring 24 is sleeved on the second guide rod 22 located below the second equalizing shaft 25, with one end fixed to the lower inner wall of the second mounting groove 21 and the other end fixed to the lower arc wall of the second equalizing shaft 25; this arrangement causes the first equalizing shaft 20 to be pressed downward by the second spring 23 (towards the foil strip), and the second equalizing shaft 25 to be pressed upward by the third spring 24 (also towards the electrode foil 11), and the first equalizing shaft 20 and the second equalizing shaft 25 elastically move towards each other, forming a moderately elastic clamping force. During operation, the electrode foil 11 enters the equalizing assembly area after being adjusted by the guide roller 12 and the tension adjusting roller 14, and the two sets of anti-wrinkle equalizing rollers 13 contact the electrode foil 11 under spring preload and apply distributed extrusion force to the foil surface. Since the anti-wrinkle equalizing rollers 13 are arranged in multiple groups, the pressure is dispersed and applied point by point in the width direction of the electrode foil 11. The elastic load provided by the second spring 23 and the third spring 24 gives the clamping force of the rollers on the electrode foil 11 a flexible and adaptive characteristic: when the electrode foil 11 has uneven thickness or slight bulges or ripples, the force change of the adjacent anti-wrinkle equalizing rollers 13 causes the equalizing shaft to slightly shift along the second guide rod 22. The springs absorb and redistribute the local load with controllable deformation. The anti-wrinkle equalizing rollers 13 gradually flatten the local protrusions in the vertical direction by rotating and smoothly transfer the stress to the adjacent area, thereby achieving a uniform flattening effect on the overall area. The double-row angular contact ball bearings ensure that the anti-wrinkle equalizing roller 13 can still rotate smoothly when subjected to radial and axial loads, reducing wear on the surface of the electrode foil 11; the fit between the guide hole and the guide rod and the sliding coating ensure the controllability of axial displacement and repeatability of positioning accuracy, avoiding lateral swaying or torsion of the shaft that would lead to uneven pressing. The foil running sequence is: guide roller 12 → tension adjusting roller 14 → anti-wrinkle equalizing roller 13 → take-up roller 15.
