Description

Technical Field

[0001] This application relates to the field of battery manufacturing technology, and in particular to an electrically controlled shearing roller structure. Background Technology

[0002] When lithium-ion battery separators are manufactured using the wet process, the separator is prone to wrinkling as it moves forward under traction. This is because the stress at each point in the lateral direction is slightly different. Furthermore, tension lines appear in the longitudinal direction of the separator, and raised ribs appear on the surface after winding. To reduce or eliminate wrinkles, tension lines, and raised ribs generated during separator production, and to flatten the separator axially, a flattening device is needed to stretch the separator, making the tension distribution more uniform in the width direction, thereby achieving the required flatness of the membrane surface.

[0003] In the wet-process lithium-ion battery separator production process, the equipment inlet is equipped with a shearing roller structure. These shearing rollers are mounted on both sides of the equipment to keep the membrane flat. The lateral position and angle of the shearing roller structure are adjustable, controlled by a cylinder. However, the existing structure uses a slide rail for lateral position adjustment and a rotating shaft for angle adjustment. After adjustment, it is fixed by a locking handle. This locking handle may loosen during long-term production, causing the shearing roller position or angle to shift, resulting in uncontrollable precision. Furthermore, the manual adjustment method is complex and cannot be adjusted online.

[0004] Therefore, there is an urgent need to provide an electrically controlled shear roll structure to solve the above-mentioned technical problems. Utility Model Content

[0027] This application provides an electrically controlled shearing roller structure, which mainly solves the problems of cumbersome adjustment of the shearing roller device, inability to adjust online, and uncontrollable adjustment position and angle accuracy in the wet process of lithium battery separator production.

[0028] The following detailed description of an electrically controlled shear roller structure in this embodiment, with reference to the accompanying drawings, is provided in detail. Figures 1-6 As shown, the electrically controlled shearing roller structures 10 are used in pairs. Each electrically controlled shearing roller structure 10 is respectively positioned on opposite sides of the width of the lithium battery separator 20, and each is supported by an equipment mounting base on the side of the width of the lithium battery separator 20. The electrically controlled shearing roller structure 10 includes a roller assembly 30, an angle adjustment assembly 40, a position adjustment assembly 50, and an electric control component 60. The roller assembly 30 can be opened or closed to tighten or loosen the separator 20. The electric control component 60 is mounted on the roller assembly 30 and is used to control the opening and closing of the roller assembly 30. The angle adjustment assembly 40 is mounted on the equipment mounting base and is used to drive the roller assembly 30 to rotate circumferentially to adjust the angle. The position adjustment assembly 50 is mounted on the equipment mounting base and is used to drive the roller assembly 30 to move horizontally to adjust its front-to-back position.

[0029] In this embodiment, the circumferential rotation of the roller assembly 30 is controlled by the angle adjustment component 40 to adjust the angle, and the horizontal movement of the roller assembly 30 is controlled by the position adjustment component 50 to adjust the front and rear positions. After the position and angle of the roller assembly 30 are properly adjusted, the opening and closing of the roller assembly 30 is controlled by the electric control component 60 to achieve the flattening effect on the diaphragm 20. This electric control method will not affect the normal operation of the equipment, can complete online adjustment, and the adjustment method is simple, the precision is controllable, and it can adapt to more production environments.

[0030] In this embodiment, it should be noted that the angle adjustment assembly 40 includes an angle adjustment servo motor 41, a worm gear 42, a worm 43, and a mounting base 44. Two oppositely arranged connecting seats 90 are mounted on the equipment mounting base. The direction of the line connecting the two connecting seats 90 is consistent with the width direction of the diaphragm 20. The angle adjustment servo motor 41 is mounted on the connecting seat 90 away from the diaphragm 20. The worm 43 is rotatably disposed between the two connecting seats 90. One end of the worm 43 passes through the connecting seat 90 and is coaxially connected to the output shaft of the angle adjustment servo motor 41, while the other end rotates on the other connecting seat 90.

[0031] The mounting base 44 is disposed between the two connecting seats 90, and a mounting groove 441 is formed in the middle of the upper surface of the mounting base 44. The mounting groove 441 is a circular groove. The worm gear 42 is rotatably mounted in the mounting groove 441. The roller assembly 30 is mounted on the upper surface of the worm gear 42 and rotates synchronously with the worm gear 42. A clearance hole 442 is formed on the side of the mounting base 44, which penetrates through the opposite sides of the mounting base 44. The axial direction of the clearance hole 442 is consistent with the axial direction of the worm 43. The side wall of the mounting groove 441 communicates with the clearance hole 442. The worm 43 passes through the clearance hole 442 and is threadedly connected to the worm gear 42 at the position where the clearance hole 442 and the mounting groove 441 communicate.

[0032] Therefore, in this embodiment, the worm gear 43 is driven to rotate by the angle adjustment servo motor 41. The worm gear 43 drives the worm wheel 42 to rotate by thread transmission. During the rotation of the worm wheel 42, it can drive the roller assembly 30 on it to rotate circumferentially in sync. In this embodiment, the angle adjustment of the roller assembly 30 adopts the worm gear transmission method. The worm gear transmission method has high adjustment accuracy and is not easy to loosen after the angle is adjusted, and has high stability.

[0033] In this embodiment, it should also be noted that a mounting plate 70 is installed between the upper end face of the worm gear 42 and the roller assembly 30. The mounting plate 70 and the worm gear 42 are coaxially arranged. The lower surface of the mounting plate 70 is connected to the middle position of the upper end face of the worm gear 42 via a connecting shaft. A support section 80 is installed on the upper end face of the mounting plate 70. The top surface of the support section 80 is connected to the roller assembly 30, and the side surface is connected to the electric control component 60. Therefore, in this embodiment, the connection between the worm gear 42 and the roller assembly 30 is achieved through the cooperation of the mounting plate 70 and the support section 80.

[0034] In some embodiments, the roller assembly 30 includes an upper roller 31 and a lower roller 32 disposed opposite to each other. The lower roller 32 is rotatably mounted on the top surface of the support section 80 and can rotate along its own axis. An electric control unit 60 connects the upper roller 31 and the side of the support section 80, and the electric control unit 60 is used to control the upper roller 31 to swing upward, thereby opening and closing the connection between it and the lower roller 32. Preferably, the top surface of the support section 80 is provided with a U-shaped frame 81, and the end of the lower roller 32 is rotatably mounted on the bottom wall of the U-shaped frame 81 opposite to its opening via a shaft.

[0035] In some embodiments, the electric control unit 60 includes a rotary cylinder 61 and a rotary arm 62. The rotary cylinder 61 is mounted on the side of the support section 80, and its output shaft is horizontally positioned. The rotary arm 62 is configured with a 90-degree bend, with one end connected to the output shaft of the rotary cylinder 61 and the other end connected to the upper roller shaft 31. Thus, the rotary cylinder 61 controls the rotary arm 62 to rotate, causing it to oscillate. During this oscillation, the upper roller shaft 31 oscillates upward relative to the lower roller shaft 32, thereby achieving the opening and closing operation between the upper and lower roller shafts 32. Preferably, the upper roller shaft 31 is rotatably mounted on the end of the rotary arm 62, and it can rotate along its own axis. Therefore, in this embodiment, both the upper roller shaft 31 and the lower roller shaft 32 are configured to rotate, allowing the diaphragm 20 to rotate between them during transmission.

[0036] In this embodiment, it should also be noted that the position adjustment assembly 50 includes a position adjustment servo motor 51 and a lead screw 52. The position adjustment servo motor 51 and the angle adjustment servo motor 41 are located on the same side. The position adjustment servo motor 51 is mounted on a connecting seat 90 away from the diaphragm 20. The lead screw 52 is rotatably disposed between the two connecting seats 90. One end of the lead screw 52 passes through the connecting seat 90 and is coaxially connected to the output shaft of the position adjustment servo motor 51, while the other end is rotatably mounted on another connecting seat 90.

[0037] The mounting base 44 has threaded holes 443 on its side. Threaded holes 443 and clearance holes 442 are symmetrically distributed on both sides of the mounting groove 441. The threaded holes 443 penetrate the opposite sides of the mounting base 44, and the axis of the threaded holes 443 is aligned with the axis of the lead screw 52. The lead screw 52 passes through the threaded holes 443 and is threadedly connected to them. Thus, the position adjustment servo motor 51 drives the lead screw 52 to rotate between the two connecting seats 90. During this rotation, the lead screw 52 moves the mounting base 44 horizontally back and forth along its axis. This movement of the mounting base 44 also moves the roller assembly 30, allowing for adjustment of the roller assembly 30's position. Furthermore, in this embodiment, the position adjustment of the roller assembly 30 uses a lead screw drive, which offers high adjustment precision, is less prone to loosening after adjustment, and exhibits high stability. Preferably, a guide post 101 is provided between the two connecting seats 90. There are two guide posts 101, one of which is located below the worm gear 43 and the other is located below the lead screw 52. Both guide posts 101 pass through the mounting base 44, and the mounting base 44 slides along the guide post 101.

[0038] The implementation principle of this embodiment is as follows: After the lithium battery separator 20 exits through the front-end equipment and reaches the lower roller 32 in the roller assembly 30, the lead screw 52 is driven to rotate by the position adjustment servo motor 51. During the rotation of the lead screw 52, ​​the mounting base 44 moves horizontally back and forth along the axis of the lead screw 52 to achieve horizontal movement of the roller assembly 30 for position adjustment. After the position adjustment is completed, the worm gear 43 is driven to rotate by the angle adjustment servo motor 41. During the rotation of the worm gear 43, the worm wheel 42 rotates through the thread transmission. During the rotation of the worm wheel 42, the roller can be driven to rotate. The component 30 rotates circumferentially to adjust the angle. After the angle adjustment is completed, the rotating arm 62 is driven to rotate by the rotary cylinder 61. The rotating arm 62 swings the upper roller shaft 31 to close with the lower roller shaft 32, thereby achieving the function of flattening the film. The electric control method used in this process will not affect the normal operation of the equipment. It has high repeatability and positioning accuracy, and can be adjusted online. The position and angle values ​​of the roller assembly 30 can be saved in the equipment control module after one adjustment. It can be recalled when the equipment is restarted. It can also be used in narrow areas and can be remotely controlled and adjusted for convenience.

[0039] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
