[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] refer to Figures 1-4 The battery winding core separation device shown includes a base plate 1 and an uncoiler 4. The uncoiler 4 has three sets. The base plate 1 has a low mounting seat 2 and a high mounting seat 3. The low mounting seat 2 has two sets, respectively positioned on both sides of the high mounting seat 3. The three sets of uncoilers 4 are respectively mounted on the low mounting seat 2 and the high mounting seat 3. The low mounting seat 2 and the high mounting seat 3 are equipped with a first drive motor 5 for driving the uncoiler 4 to rotate. The first drive motor 5 drives the uncoiler 4 through gears. With the three sets of uncoilers 4, when separating the battery winding core, the uncoiler 4 remains in an open state. After the battery winding core separation is completed, the uncoiler 4 retracts, causing the winding core on the uncoiler 4 to... The material is easy to remove, avoiding the problem of it being too tightly wrapped on the roller and difficult to remove. The base plate 1 is also provided with a clamping mechanism 8 corresponding to the position of the high mounting seat 3. A placement block 14 is provided between the high mounting seat 3 and the clamping mechanism 8. The left and right sides of the placement block 14 are provided with centering mechanisms 6 for centering the battery core. The centering mechanism 6 is connected with a gripper 63. The base plate 1 is provided with a bidirectional threaded rod 7. The centering mechanism 6 slides on the surface of the base plate 1 through the bidirectional threaded rod 7. The base plate 1 is provided with a guide groove 13 corresponding to the position of the bidirectional threaded rod 7. The high mounting seat 3 is also provided with a turntable 12. The base plate 1 is provided with a second drive motor 10 for driving the turntable 12 to rotate.

[0022] As one embodiment of this invention, in order to prevent the battery core from shifting during core separation, the clamping mechanism 8 further includes a clamping block 9 and a mounting platform 17. The clamping block 9 is slidably connected to the mounting platform 17 via a guide rod 18. The mounting platform 17 has a through hole adapted to the clamping block 9. The mounting platform 17 is equipped with a cylinder 16 for driving the clamping block 9 to move back and forth. The clamping block 9 is equipped with a rotating base, which is located on the same axis as the turntable 12. The high mounting base 3 has a through hole for connecting the second drive motor 10 and the turntable 12. The second drive motor 10 passes through the through hole and is connected to the turntable 12.

[0023] As one implementation method in this embodiment, in order to eliminate the need for multiple alignments by the operator when clamping the battery core, a handle 11 is connected to the bidirectional threaded rod 7, and a placement slot 15 for placing the battery core is provided on the placement block 14. The centering mechanism 6 also includes a slider 61 and a connecting plate 62. The slider 61 has a threaded hole adapted to the bidirectional threaded rod 7. The gripper 63 is connected to the slider 61 through the connecting plate 62. The guide groove 13 is adapted to the connecting plate 62. There are two sets of centering mechanisms 6, and the two sets of centering mechanisms 6 are symmetrically arranged on both sides of the placement block 14. The grippers 63 on the two sets of centering mechanisms 6 are staggered. The staggered grippers 63 allow the battery core in the placement slot 15 to be clamped by the two sets of grippers 63. Due to the arc-shaped setting of the grippers 63, the centering mechanism 6 moves the battery core to a position on the same axis as the turntable 12, which facilitates the clamping mechanism 8 to fix and clamp it.

[0024] The working principle of this utility model is as follows: First, the disassembled battery coil is placed in the placement slot 15 on the placement block 14. Then, by rotating the handle 11, the bidirectional threaded rod 7 rotates. Under the action of the two sets of oppositely oriented threaded segments on the bidirectional threaded rod 7, the two sets of centering mechanisms 6 connected to the bidirectional threaded rod 7 move towards the placement block 14, causing the grippers 63 to clamp the battery coil in the placement slot 15, ensuring that the battery coil and the turntable 12 are on the same axis. Then, the cylinder 16 is controlled by the PLC, causing the clamping block 9 to slide in the mounting platform 17. Under the action of the guide rod 18, the clamping block 9 will not shift. The clamping block 9 pushes the rotating base to clamp the battery coil onto the turntable 12. After clamping, by rotating the handle 11 in the opposite direction, the two sets of centering mechanisms 6 no longer clamp the battery coil and simultaneously move it out of the equipment's working range, preventing damage during the winding process. Interference occurs during winding. Subsequently, the PLC controller controls the three sets of unwinding machines 4 to remain open. Then, one end of the positive electrode core, negative electrode core, and film of the battery core are wound onto the three sets of unwinding machines 4 respectively. Then, the PLC controller starts the first drive motor 5 and the second drive motor 10. The second drive motor 10 drives the battery core between the turntable 12 and the rotating chassis to rotate and loosen the core. The three sets of first drive motors 5 drive the three sets of unwinding machines 4 to rotate respectively. The three sets of unwinding machines 4 drive the positive electrode core, negative electrode core, and film to rotate and wind them onto the corresponding unwinding machines 4. After winding, the PLC controller tightens the unwinding machines 4 so that they are no longer tensile on the wound core and film. Then, the workers can easily remove the separated core and film from the unwinding machines 4, avoiding the problem of the film being too tightly wrapped with the winding roller in traditional equipment.
