[0002] During the battery manufacturing process, the raw materials are led out through the unwinding mechanism, and the rewinding mechanism rewinds the raw materials into battery cells. However, during the rewinding process, the tension of the lithium battery material changes due to the inconsistency between the rewinding speed and the unwinding speed.
[0003] In order to ensure consistent tension during the winding process, a tension adjustment device is required to compensate for the tension, thereby controlling the unwinding speed of the unwinding mechanism to form a closed loop of the tension control system.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Please refer to Figures 1 to 4 The utility model proposes a low-damping tension adjustment device. The preferred embodiment of the low-damping tension adjustment device of the utility model includes a fixed seat 1, a roller assembly 2, a roller assembly mounting seat 3, a follower wheel assembly 4, a tension adjustment rope 5, a driving wheel 6 and a driving motor 7.
[0024] The driving motor 7 is arranged below the fixed seat 1, the driving wheel 6 is connected to the output shaft of the driving motor 7, the roller assembly mounting seat 3 is laterally slidably arranged on the fixed seat 1, the roller assembly 2 is fixedly arranged on the roller assembly mounting seat 3, the follower wheel assembly 4 is arranged on one side of the fixed seat 1, one end of the tension adjustment rope 5 is fixedly connected to the driving wheel 6, and the other end is fixedly connected to the roller assembly mounting seat 3 after passing through the follower wheel assembly 4.
[0025] like Figure 3 and Figure 4 As shown, when the raw material 13 is tightened toward the right side of the roller assembly 2, the drive motor 7 rotates counterclockwise, and then pulls the roller assembly 2 through the tension adjustment rope 5, and the unwinding speed is accelerated. On the contrary, when the raw material 13 is loosened toward the left side of the roller assembly 2, the winding speed is slowed down, and the tension adjustment rope 5 follows, and the roller assembly 2 returns to the middle value. Therefore, through the closed-loop control of the unwinding speed and the tension adjustment device, the winding tension is in the middle value of the fluctuation range, ensuring that the tension of the winding process is stable and consistent.
[0026] Furthermore, in this embodiment, the tension adjustment rope 5 is a steel wire rope. The steel wire rope drive can meet the low damping and no inertia conditions. The low damping tension adjustment device using the steel wire rope has a faster response speed and higher precision, and can more effectively reduce the fluctuation value of the winding tension, thereby improving the quality and yield of the wound battery cell.
[0027] Furthermore, in this embodiment, the follower assembly includes a protective cover 8 disposed on one side of the fixing seat 1 , and a first follower wheel 9 and a second follower wheel 10 disposed in the protective cover 8 in the up-down direction.
[0028] In this embodiment, one end of the wire rope is fixed to the driving wheel 6, and the other end is fixed to the roller assembly mounting seat 3 after passing the first follower wheel 9 and the second follower wheel 10. In this embodiment, the protective cover 8 can improve the safety and service life of the low damping tension adjustment device.
[0029] Furthermore, in this embodiment, the low-damping tension adjustment device further includes roller assembly limiters 11 disposed on both sides of the fixed seat 1. The roller assembly limiters 11 can prevent the roller assembly 2 from moving beyond the limit, thereby ensuring that the winding tension is at the middle value of the fluctuation range, and ensuring that the tension of the winding process is stable and consistent.
[0030] Furthermore, in this embodiment, a guide rail 12 is longitudinally arranged on the fixing seat 1 , and the roller assembly mounting seat 3 is slidably arranged on the guide rail 12 .
