[0012] Preferably, the guide rod is installed at a position close to the cylinder, there are two guide rods, and the two guide rods are symmetrically installed along the cylinder, and the winding roller is sleeved on the support rod at the center of the driving disk, so as to facilitate the installation of the winding roller, and utilize the right-angle locking rod and the card slot to facilitate the winding roller to rotate smoothly to wind up the positive and negative metal composite materials of the lithium battery;

[0023] The present invention provides a winding and deviation correction device for positive and negative electrode metal composite materials of lithium batteries. It has the following beneficial effects:

[0024] 1. The winding and deviation correction device for the positive and negative electrode metal composite materials of the lithium battery can clamp the winding roller by using the cooperation between the auxiliary component and the support rod at the center of the driving disk, and can drive the driving disk to rotate clockwise by rotating the output end of the servo motor, thereby driving the winding roller to rotate, and the positive and negative electrode metal composite materials of the lithium battery are wound by the continuous rotation of the winding roller, and the rotation speed of the winding roller can be controlled to adjust the winding speed of the positive and negative electrode metal composite materials of the lithium battery.

[0025] 2. The winding and deviation correction device for the positive and negative metal composite materials of lithium batteries utilizes the contraction of the output end of the cylinder and, under the support and guiding action of the guide rod, enables the support plate to drive the connecting top cone to move to the side close to the winding roller, and combines the position of the right-angle locking rod with the position of the card slot. By embedding the right-angle locking rod into the inside of the card slot, the winding roller can be self-locked, and under the rotation support of the connecting top cone, the winding roller and the drive disk can be operated synchronously.

[0026] 3. The winding and deviation correction device for the positive and negative electrode metal composite materials of the lithium battery is convenient for installing the winding roller by sleeve-mounting the winding roller on the support rod at the center of the driving disk, and utilizes the clamping connection between the right-angle locking rod and the card slot to promote the smooth rotation of the winding roller to wind up the positive and negative electrode metal composite materials of the lithium battery, and extends the right-angle locking rod from the card slot by extending the output end of the cylinder, so as to facilitate the disassembly of the winding roller after winding, thereby making the installation and disassembly of the winding roller convenient.

[0027] Fourth, the winding and correcting equipment of the positive and negative metal composite materials of the lithium battery utilizes the extension of the output end of the electric telescopic rod to push the flat plate downward, and uses the cylinder to press the positive and negative metal composite materials of the lithium battery. At the same time, the symmetrical supporting legs on both sides are used to drive the cylinder to move outward, and the spring is stretched, so that the positive and negative metal composite materials of the lithium battery can be tensioned, so that the winding roller can wind the composite materials more tightly and the winding effect is good.

[0028] 5. The winding and deviation correction device for the positive and negative metal composite materials of the lithium battery moves toward the position of the winding roller, and uses a spiral wire to fit the composite material. Under the rotation connection of the cylinder, the spiral wire rotates, and the two symmetrical spiral wires with opposite thread directions are used to make the wound composite material receive a driving force toward the middle, thereby correcting the moving composite material and preventing it from running off the track.

[0029] 6.

When the toggle teeth are separated from the force-bearing sheet, and under the action of the elastic force provided by the reset spring sheet, the frame drives the correcting component as a whole to move in the opposite direction for reset, and then uses the reciprocating movement of the spiral line to keep the composite material flat and not prone to wrinkles.

[0030] 7. The winding and deviation correction equipment for the positive and negative metal composite materials of the lithium battery supports the composite materials through the first roller, the second roller and the third roller, so that the composite materials move smoothly and are not prone to jamming. The elastic force provided by the conical elastic part is used to make the symmetrical surfaces of the wiping rods on both sides fit with the composite materials. As the composite materials continue to move, the wiping rods can be used to wipe the surface of the composite materials to promptly remove dust and debris attached to the surface of the composite materials, thereby pre-treating the composite materials.

The spiral wire 456 is symmetrical and has opposite thread directions, so that the composite material being wound is driven toward the middle, thereby correcting the deviation of the composite material in motion.

[0069] As the driving disc 31 rotates, the toggle teeth 33 are driven to rotate in a circle, and the toggle teeth 33 are in contact with the force-bearing sheet 44. As the toggle teeth 33 continue to rotate, the force-bearing sheet 44 is pushed toward the side close to the guide roller 2, so that the force-bearing sheet 44 applies the pushing force to the frame 42, and under the sliding connection of the slider 41, the deviation-correcting assembly 45 moves as a whole toward the side away from the winding roller 34, and the reset spring sheet 43 is compressed;

[0070] When the toggle tooth 33 is separated from the force-bearing sheet 44, the frame 42 drives the deviation-correcting assembly 45 to move in the opposite direction as a whole to reset under the elastic force provided by the reset spring sheet 43, and then the spiral line 456 moves back and forth to keep the composite material flat;

[0071] After the lithium battery positive and negative electrode metal composite materials are wound up using the winding roller 34, the right-angle locking rod 365 can be disengaged from the card slot 35 by extending the output end of the cylinder 361, so that the wound winding roller 34 can be disassembled, thereby removing the winding roller 34 and facilitating the subsequent installation of a new winding roller 34 for winding.

[0072] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
