[0022] Embodiment

[0023] Please refer to Figures 1 to 4 As shown, this embodiment provides an intelligent tension control system for a semi-automatic winding machine, including: a mounting plate 1, on one side of which a first driven roller 2, a second driven roller 3 and an active winding roller 4 are rotatably mounted; a tension detection member, which is mounted on the mounting plate 1 and is located at the first driven roller 2; a tension adjusting member, which is mounted between the second driven roller 3 and the active winding roller 4, the tension adjusting member contacts the winding material and adjusts the tension of the winding material; and a controller 9, which is fixedly mounted on the back of the mounting plate 1, the controller 9 is electrically connected to the tension detection member and the tension adjusting member. By the combined use of the tension detection member, the tension adjusting member and the controller 9, it is possible to realize real-time monitoring and automatic adjustment of the tension during the winding process of the semi-automatic winding machine, ensure the winding quality of the lithium battery winding material, improve the winding accuracy and consistency, reduce the scrap rate, and improve the overall performance of the battery.

[0024] Among them, the tension detection member is a tension sensor 5, the tension sensor 5 is fixedly mounted on the mounting plate 1, the tension sensor 5 contacts the winding material, the type of the tension sensor 5 is a cantilever type, and its model is CLTL. By contacting the lithium battery winding material with the tension sensor 5, it is possible to detect the tension of the lithium battery winding material during the winding process in real time to accurately measure the magnitude of the tension of the lithium battery winding material.

[0025] Among them, the first driven roller 2 and the second driven roller 3 are at the same use height, and the tension sensor 5 is located below the coil material, which can ensure that the tension sensor 5 can effectively contact and detect the lithium battery coil material.

[0026] Among them, the tension adjusting member includes a mounting block 7, a tension adjusting roller 702, and a hydraulic cylinder 8. A support plate 101 is fixedly installed on the back surface of the mounting plate 1. The hydraulic cylinder 8 is fixedly installed on the support plate 101. The telescopic end of the hydraulic cylinder 8 is fixedly connected to the bottom of one end of the mounting block 7. Mounting holes 6 are formed in the mounting plate 1. The mounting block 7 is placed inside the mounting holes 6. One end of the mounting block 7 is rotatably installed with a tension adjusting roller 702 through a bearing 701. The tension adjusting roller 702 is flush with the winding widths of the first driven roller 2, the second driven roller 3, and the active winding roller 4.

[0027] Among them, by starting the hydraulic cylinder 8, the mounting block 7 can be driven to displace, and then the tension adjusting roller 702 can be driven to displace. During the displacement of the tension adjusting roller 702, the lithium battery coil material can be driven to be tensioned or relaxed, thereby realizing the adjustment of the winding tension of the lithium battery coil material.

When the tension sensor 5 is not in contact with the lithium battery coil material, the alarm 10 can transmit a signal to the controller 9. The controller 9 controls the alarm 10 to give an alarm to remind the staff to come for debugging quickly. The model of the alarm 10 is SL-125, and the controller 9 can select an S7-200 ultra-small PLC controller.

When the tension of the lithium battery winding material is greater than or less than the set value, the tension sensor 5 transmits a signal to the controller 9. The controller 9 starts the hydraulic cylinder 8 according to the set value, which can drive the mounting block 7 to displace. The displacement of the mounting block 7 drives the tension adjusting roller 702 to displace. During the displacement of the tension adjusting roller 702, it can drive the lithium battery winding material to be tightened or loosened until the tension of the lithium battery winding material is adjusted to the set value, realizing real-time monitoring and automatic adjustment of the tension during the winding process, ensuring the winding quality of the lithium battery winding material, improving the winding accuracy and consistency, reducing the waste rate, and enhancing the overall performance of the battery.
