The limiting component 2 also includes a second rotating roller 23, which is connected to the inner wall of the fixing frame 21 via a bearing. A winding component 3 is fixedly installed on the top of the base plate 1. The winding component 3 includes a support frame 31 and a first motor 32. The support frame 31 is fixedly installed on the top of the base plate 1, and the first motor 32 is fixedly installed on one side of the support frame 31. The output end of the first motor 32 is fixedly connected to a winding roller 33. The top of the base plate 1 is fixedly installed with... The system includes a centering component 4 and a material handling component 5 fixedly installed on the top of the base plate 1. The centering component 4 includes an L-shaped frame 41 and a second motor 42. The L-shaped frame 41 is fixedly installed on the top of the base plate 1, and the second motor 42 is fixedly installed on the top of the L-shaped frame 41. A threaded rod 43 is fixedly connected to the output end of the second motor 42. A lifting block 44 is threadedly connected to the side wall of the threaded rod 43. A connecting rod 45 is hinged to both sides of the lifting block 44. A movable frame 46 is hinged to one side of the connecting rod 45. A centering plate 47 is fixedly installed on one side of the movable frame 46. The centering component 4 also includes a sliding plate 48 and a sliding groove 49. The sliding plate 48 is fixedly installed at the bottom of the movable frame 46, and the sliding groove 49 is opened at the top of the base plate 1. The sliding plate 48 and the sliding groove 49 are slidably connected.

[0032] In this embodiment, after the motor 32 starts, it drives the winding roller 33 to rotate. At this time, relevant materials for lithium battery production, such as separators, positive and negative electrode sheets, can be placed on the winding roller 33 for winding. The rotating roller 22 and the rotating roller 23 are connected to the inner wall of the fixed frame 21 through bearings. They can limit and guide the passing materials to ensure that the materials can accurately enter the winding roller 33 and avoid positional deviation, thus ensuring the smooth progress of the winding process. Then, the motor 42 starts and drives the threaded rod 43 to rotate. Since the lifting block 44 is threadedly connected to the threaded rod 43, the lifting block 44 will move up and down along the threaded rod 43 when it rotates. During the movement of the lifting block 44, the moving frame 46 is driven to move through the connecting rod 45.

The rectangular plate 55 and the stabilizing groove 56 are slidably connected.

[0034] In this embodiment, the electric push rod 52 works under the support of the stabilizer 51. Its extension and retraction drive the connecting plate 53 to move, thereby causing the lifting plate 54 and the rectangular plate 55 to move accordingly. The rectangular plate 55 slides along the stabilizing grooves 56 on both sides of the stabilizer 51 to ensure the stability of the movement. After the winding is completed, the lifting plate 54 can be moved to the bottom of the winding roller 33 to facilitate the removal of the wound product and complete the entire workflow.

[0035] Working principle: After motor 1 32 starts, it drives the winding roller 33 to rotate. At this time, relevant materials for lithium battery production, such as separators, positive and negative electrode sheets, can be placed on the winding roller 33 for winding. The rotating roller 1 22 and rotating roller 23 are connected to the inner wall of the fixed frame 21 through bearings. They can limit and guide the passing materials to ensure that the materials can accurately enter the winding roller 33 and avoid positional deviation, thus ensuring the smooth progress of the winding process. Then, motor 2 42 starts and drives the threaded rod 43 to rotate. Since the lifting block 44 is threadedly connected to the threaded rod 43, the lifting block 44 will move up and down along the threaded rod 43 when it rotates. During the movement of the lifting block 44, the moving frame 46 is driven to move through the connecting rod 45. The sliding plate 48 at the bottom of the moving frame 46 slides along the sliding groove 49 on the base plate 1 to ensure that the moving frame 46 can move smoothly, thereby driving the centering plate 47 to move. The centering plate 47 can center and position the material to be wound, making the winding more regular.

[0036] The electric push rod 52 works under the support of the stabilizer 51. Its extension and retraction drive the connecting plate 53 to move, which in turn causes the lifting plate 54 and the rectangular plate 55 to move. The rectangular plate 55 slides along the stabilizing grooves 56 on both sides of the stabilizer 51 to ensure the stability of the movement. After winding is completed, the lifting plate 54 can be moved under the winding roller 33 to facilitate the removal of the wound product and complete the entire workflow.
