Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery pole piece winding, and more particularly to a winding device for a laser-cut pole tab forming machine. Background Art

[0002] After the processing of the tab is completed, it needs to be wound to facilitate transportation and storage. The traditional tab winding device directly winds the tab through a winding roller. The tab is prone to offset during the winding process, which causes the tab to be in a scattered state after winding and requires manual adjustment. To address this, the existing technology often uses a traction member set at the end of the winding roller to adjust the tab winding. However, due to the traction requirement, such traction members are all set vertically relative to the winding roller, which directly causes such traction members to contact the tab that has been wound below while achieving traction of the upper tab, thereby wearing the lower tab that has been wound during the winding process, causing serious wear of the lower tab, affecting the overall quality of the tab. Therefore, there is a need for a laser cutting tab forming machine winding device that can adjust the tab position during winding and avoid wearing the lower tab during the winding process.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, wherein the same components are represented by the same reference numerals.

[0025] Reference Figure 1-3A winding device for a laser cutting ear forming machine includes a frame 1, a tightening roller group 2 and a material guide 3. A winding roller 4 is rotatably provided on the frame 1. The winding roller 4 includes an inner rod 5 and an outer roller body 6. The inner rod 5 is fixedly connected to the frame 1. The outer roller body 6 is sleeved with the inner rod 5 and is rotatably connected to the inner rod 5. A driving motor 7 is provided on the frame 1. A connecting gear 8 is provided on the side of the outer roller body 6 close to the frame 1. A driving gear 8 is provided at the output end of the driving motor 7. The driving gear 8 and the connecting gear 8 are meshed with each other. The tightening roller group 2 includes two tightening roller bodies 10 , the two tightening rollers 10 are rotatably connected to the frame 1, and the outer sides of the two tightening rollers 10 form tightening surfaces 11 and are used to adhere to the two sides of the pole ear respectively. The two tightening rollers 10 are used to keep the pole ear in a taut state. Further preferably, an elastic layer 12 is formed on the outer side of the tightening roller 10, and the tightening surface 11 is the outer side of the outer elastic layer 12. The elastic layer 12 can maintain tightening while protecting the pole ear. A damper is provided on one side of the two tightening rollers 10, and the number of guide members 3 is 2 and is respectively provided on both sides of the outer roller 6. , the two material guides 3 each include a traction rod 13 and a driving member 14. The traction rod 13 is arranged at an angle relative to the outer roller body 6 to keep the traction rod 13 in contact with the upper pole ear. The driving member 14 is connected to the traction rod 13 and is used to drive the traction rod 13 away from the end of the outer roller body 6 to swing toward the outer roller body 6. The two traction rods 13 are used to respectively contact the two sides of the pole ear and pull the pole ear toward the middle section of the outer roller body 6. When in use, the pole ear is passed between the two tightening roller bodies 10 and wound on the outer roller body 6, and the motor 7 is further driven to drive the outer roller body 6. The roller body 6 rotates so that the tab is continuously wound on the outer roller body 6, and the tab is kept taut by the two tightening roller bodies 10. As the tab is wound, the driving member 14 continuously adjusts the angle of the traction rod 13 so that the traction rod 13 always contacts the two sides of the tab above to keep the tab winding stable and reduce the deviation of the tab. At the same time, due to the inclined setting of the traction rod 13, the traction rod 13 is separated from the tab below, so that the tab below will not be worn during the tab winding process, thereby improving the overall quality of the tab after winding.

[0026] Reference Figure 4 The material guide member 3 also includes a mounting seat 15 and an insertion rod 16. The mounting seat 15 is installed on the inner rod 5. The driving member 14 is connected to the mounting seat 15. The output end of the driving member 14 is connected to one end of the insertion rod 16. A socket 17 is provided at one end of the traction rod 13 corresponding to the insertion rod 16. One end of the insertion rod 16 is inserted into the socket 17 and is rotatably connected to the traction rod 13, so that the traction rod 13 can rotate with the winding of the pole ear when the pole ear is wound, thereby reducing the wear of the traction rod 13 on the pole ear located above.

[0027] Reference Figure 4The driving member 14 is a driving motor. In one embodiment, the output end of the driving motor is directly connected to the insertion rod 16 and drives the insertion rod 16 to rotate. In this embodiment, an accommodating cavity 18 is provided on the mounting seat 15 and is rotatably connected to a turntable 19. The insertion rod 16 is fixedly mounted on the outside of the turntable 19. A spring 20 is provided in the accommodating cavity 18. One end of the spring 20 is connected to the output end of the driving motor, and the other end is connected to the turntable 19. The driving motor is used to control the elastic force of the spring 20. When in use, the driving motor rotates, thereby driving the spring 20 to tighten or relax, thereby realizing the adjustment of the elastic force of the spring 20. The setting of the spring 20 can drive the insertion rod 16 to move through the elastic force, thereby avoiding the rigid connection with the insertion rod 16, thereby protecting the pole ear.

[0028] Reference Figure 1 and Figure 5, also includes a connecting member 21. In order to extend the traction range of the traction rod 13, in this embodiment, the two traction rods 13 are staggered along the length direction of the inner rod 5. The connecting member 21 is arranged between the two traction rods 13. Through holes 22 are respectively provided on both sides of the connecting member 21 corresponding to the two traction rods 13. A connecting rod 23 is slidably provided in the through hole 22. One end of the connecting rod 23 away from the connecting member 21 is movably connected to the traction rod 13. The traction rod 13 is used to drive the connecting rod 23 to extend out of the through hole 22. A sensing chamber 24 is provided in the connecting member 21 and in the sensing chamber 24. A balance bar 25 is provided, and an angle sensor 26 is provided on the connecting member 21. The input end of the angle sensor 26 is connected to the middle section of the balance bar 25. Further preferably, in this embodiment, heavy ends 27 are formed at both ends of the balance bar 25 to make the balance bar 25 more stable. When in use, when the angle of the traction rod 13 changes as the tab is wound, the traction rod 13 drives the connecting rod 23 to extend from the through hole 22. When the tab is offset, the angles of the traction rods 13 on both sides are different from each other, thereby causing the connecting member 21 to be tilted, thereby driving the angle sensor 26. The balance bar 25 rotates relative to the balance bar 25, so that the input end of the angle sensor 26 can receive an angle change signal. The drive motors on both sides further control the spring 20 on one side to change the elastic force, thereby adjusting the offset tab. For example, when the tab deviates to the left, the left traction rod 13 tilts at a greater angle than the right traction rod 13, causing the connecting member 21 to rotate clockwise. The rotation of the connecting member 21 further drives the angle sensor 26 to rotate clockwise relative to the balance bar 25, thereby causing the angle sensor 26 to receive a rotation signal. The offset side of the tab is confirmed by the difference in the forward and reverse rotation signals relative to the balance bar 25. The left drive motor is further controlled to tighten the spring 20, increasing the elastic force of the left spring 20, thereby increasing the traction force of the left traction rod 13, and driving the tab to deviate to its original position. After the tab deviates to its original position, the connecting member 21 rotates again, the angle sensor 26 receives the signal, and readjusts the tension of the spring 20 via the drive motor, so that the traction forces of the traction rods 13 on the left and right sides are consistent, thereby maintaining the tab position unchanged.

[0029] Reference Figure 6 The end of the connecting rod 23 away from the connecting member 21 is the connecting end and is provided with a mounting cavity 28. The end of the traction rod 13 away from the outer roller body 6 is provided with a spherical hinge 29 and is connected to the mounting cavity 28 with a spherical pair. A sliding groove 30 is provided on the connecting end and is connected to the mounting cavity 28. The sliding groove 30 is used for the traction rod 13 to slide. The connection method of the spherical pair can facilitate the rotation of the traction rod 13 relative to the connecting member 21. The setting of the sliding groove 30 allows the traction rod 13 to slide in the sliding groove 30 when the angle changes.

[0030] Reference Figure 1 and Figure 7The outer roller body 6 includes a plurality of connecting roller bodies 31 connected in sequence. Corresponding connecting blocks 32 and connecting grooves 33 are respectively provided on both sides of the connecting roller body 31. The connecting blocks 32 are used to insert into the corresponding connecting grooves 33 of adjacent connecting roller bodies 31 to achieve mutual connection. By setting a plurality of connecting roller bodies 31, the length of the connecting roller body 31 can be adjusted to adapt to the pole ears of different widths. At the same time, setting the connecting blocks 32 on the side can keep the outer side of the connecting roller body 31 in a smooth state, thereby avoiding damage to the pole ears.
