In addition, the existing equipment fails to effectively eliminate the gaps and air inside the battery cell during the winding process.

At this time, the first guide roller 42 and the second guide roller 43 on the guide assembly 40 work together to effectively gather the diaphragm and the pole piece, and guide them to pass between the clamping seat 31 and the clamping block 33 on the clamping assembly 30; in the clamping assembly 30, based on the elastic force of the clamping spring 34, the clamping block 33 is pushed to stack and extrude the diaphragm sheet and the pole piece, ensuring that the two diaphragm sheets are tightly fitted to wrap the pole piece, thereby forming a battery cell, and through A lower protective layer 311 and an upper protective layer 331 are respectively provided on the pressing seat 31 and the pressing block 33, and the protective layers are used to enhance the extrusion of the battery core stack while avoiding possible damage to the battery core during the pressing process; the formed battery core is then guided to the winding core 57 of the winding component 50 by the guide component 40 on the other side. At this time, through program control, the servo motor 52 is started and generates kinetic energy, and its output end drives the active gear plate 53 to rotate, and under the joint action of the active gear plate 53, the driven gear plate 54 and the transmission belt 55, the movable shaft 56 starts to rotate, and drives the winding core 57 assembled on the movable shaft 56 to rotate synchronously, and then the rotating winding core 57 is used to guide the battery core to be gradually wound around its periphery, thereby performing the winding operation of the battery core;

[0071] During the cell winding process, the bonding block 66 on the bonding mechanism 60 is in close contact with the outer side of the winding core 57, which can realize continuous pressing of the winding core 57. During this process, the bonding block 66 can always be in adaptive bonding contact with the outer side of the winding core 57 and continuously press the winding core 57. This setting can prevent the winding core 57 from loosening during the winding process, effectively prevent the cell from being easily deformed during the winding process, and ensure the tightness and consistency of the cell structure. As the diameter of the cell roll gradually increases, the bonding block 66 is pressed on the spring rod 6 5, the laminating block 66 is always attached to the battery cell roll under the action of the laminating block 66, and the pressure of the increased diameter of the battery cell roll pushes the laminating block 66 to move toward the inside of the laminating shell 62, and the inclined surface of the fixed inclined block 63 and the laminating block 66 are in contact with each other, so that the laminating block 66 is guided to move outward along the center of the battery cell roll under the action of the guide assembly 64. In this process, the laminating block 66 not only moves in the vertical direction, but also moves in the horizontal direction, so that the gap and air inside the battery cell roll can be discharged from the battery cell roll by using this force, thereby improving the winding quality of the battery cell roll;

[0072] In addition, when the bonding block 66 moves outward from the center of the battery cell roll, the spring rod 65 is used to drive the guide slider 642 to slide on the guide rod 641. The guide slider 642 squeezes the support spring 643 during the sliding process, and the sliding of the guide slider 642 on the guide rod 641 further enhances the movement effect of the bonding block 66. When the guide slider 642 slides on the guide rod 641, the damping block 6421 on the inner side of the guide block is driven to continuously move under the elastic force of the fixing spring 6422. The guide rod 641 extends and retracts, and continuously engages and separates with the damping groove 6412 on the outer wall of the guide rod 641. In the process of the damping block 6421 engaging with the damping groove 6412, additional resistance is generated, so that the guide slider 642 produces a setback effect in the process of sliding on the guide rod 641, and this setback force acts on the fitting block 66 synchronously, thereby strengthening the extrusion effect of the fitting block 66 on the battery cell roll, further squeezing out the gaps and air inside the battery cell roll, thereby improving the winding quality of the battery cell roll;

[0073] And when the bonding block 66 moves to the predetermined position, at this time, the bonding block 66 drives the knocking piece 661 to knock and push the sensing block 674 on the sensing component 67, driving the sensing block 674 to drive the second fixed plate 672 to squeeze the elastic corrugated rubber ring 673, and the second fixed plate 672 moves while driving the first sensing sheet 675 to move synchronously, prompting the first sensing sheet 675 and the second sensing sheet 676 to contact each other, and send out an electrical signal to drive the servo motor 52 to stop running, thereby realizing the automatic stop of the battery cell winding operation, and further improving its degree of automation.
