Description

Technical Field

[0001] This utility model relates to the field of tension control technology, specifically to a high-speed winding tension control device for power battery electrode sheets. Background Technology

[0002] A power battery is a power source that provides power to tools, often referring to the batteries that power electric vehicles, electric trains, electric bicycles, and golf carts. Power batteries are the core components of new energy vehicles and an important direction for future energy transformation. During the processing of power batteries, the battery electrodes need to be wound at high speed. For example, in the processing of lithium batteries, the tension needs to be precisely controlled during the electrode winding process to ensure the uniformity, tightness, and alignment of the battery cells, thereby improving the safety and performance of the battery.

[0003] The prior art discloses a tension control device for manufacturing lithium batteries, application number CN201520189521.6. This utility model mounts a tension roller assembly on a swing arm. The swing arm has a constant lever arm length at different angles, and a servo motor provides a certain torque to the tension roller assembly to regulate the tension experienced by the power battery electrode sheets during high-speed winding. However, the tension roller assembly in this structure is fixed in position on the swing arm. While it is convenient for tension control of power battery electrode sheets at a certain installation height, the inability to adjust the position of the tension roller assembly on the swing arm due to the varying installation heights of the power battery electrode sheet winding equipment affects the applicability of the control device. To address the shortcomings of this utility model, those skilled in the art have proposed a high-speed winding tension control device for battery electrode sheets. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-speed winding tension control device for power battery electrode sheets. It features an adjustable tension roller assembly on the swing arm to accommodate the needs of different winding and unwinding equipment, allowing for adjustment of the lever arm length. This device has the advantages of wider applicability and greater practicality, thereby solving the problems mentioned in the background technology.

[0005] To achieve the aforementioned adjustable tension roller assembly's position on the swing arm, thus adapting to the needs of different winding and unwinding equipment requiring adjustable lever arm length, and offering wider applicability and greater practicality, the specific technical solution adopted by this utility model is as follows: A high-speed winding tension control device for power battery electrode sheets includes a mounting plate, a motor frame, a swing arm, a tension shaft, and a tension roller. The motor frame is fixedly mounted on the bottom surface of the mounting plate, and a servo motor is mounted on one side of the motor frame. The output end of the servo motor is connected to and mounted on the tension shaft. A rotating shaft sleeve is mounted on the motor frame, and the rotating shaft sleeve is inner... A tension shaft is connected, and a potentiometer is installed at one end of the shaft sleeve. One end of the tension shaft is connected to one end of a coupling, and the other end of the coupling is connected to the potentiometer input shaft. A swing arm is fixedly installed on the tension shaft, and an adjusting groove is opened on one side of the swing arm. One end of the adjusting groove is connected to the output end of an adjusting motor. An adjusting slider is embedded in the adjusting groove, and a first lead screw sleeve is fixedly installed on the adjusting slider. The first lead screw sleeve cooperates with the adjusting lead screw. An adjusting seat is fixedly installed on one side of the adjusting slider, and tension rollers are symmetrically installed on the adjusting seat.

[0006] Furthermore, an extension plate is symmetrically fixedly installed on the adjusting seat, and a mounting shaft seat is symmetrically installed on the extension plate. A bidirectional lead screw is installed on the mounting shaft seat. A correction ring plate is symmetrically sleeved on both tension rollers. A second lead screw sleeve is fixedly installed on the correction ring plate, and the second lead screw sleeve cooperates with the bidirectional lead screw.

[0007] Furthermore, a knob is connected to one end of the bidirectional lead screw.

[0008] Furthermore, a control panel is installed on the side wall of the motor frame, and the control panel is electrically connected to the servo motor, the regulating motor and the potentiometer.

[0009] Furthermore, the cross-sectional shape of the adjusting groove and the adjusting slider is T-shaped.

[0010] Furthermore, the inner wall of the correction annular plate abuts against the side wall of the tension roller.

[0011] Compared with the prior art, this utility model provides a high-speed winding tension control device for power battery electrode sheets, which has the following beneficial effects: (1) This utility model is provided with an installation plate, a motor frame, a swing arm, a tension shaft, and a tension roller. The motor frame is fixedly installed on the bottom surface of the installation plate, and a servo motor is installed on one side of the motor frame. The output end of the servo motor is connected to the tension shaft. A rotating shaft sleeve is installed on the motor frame, and the tension shaft is sleeved inside the rotating shaft sleeve. A potentiometer is installed on one end of the rotating shaft sleeve. One end of the tension shaft is connected to one end of a coupling, and the other end of the coupling is connected to the potentiometer input shaft. A swing arm is fixedly installed on the tension shaft, and an adjustment groove is opened on one side of the swing arm. One end of the adjustment groove is connected to the output end of the adjustment motor. An adjustment slider is embedded in the adjustment groove, and a first lead screw sleeve is fixedly installed on the adjustment slider. The first lead screw sleeve cooperates with the adjustment lead screw. An adjustment seat is fixedly installed on one side of the adjustment slider, and tension rollers are symmetrically installed on the adjustment seat. During installation, the user can fix the equipment on the machine device through the installation plate, and then adjust the height position of the battery electrode winding and unwinding according to the height position. The adjustment mechanism uses a motor to drive the adjusting screw, which in turn moves the tension roller along the adjusting groove. By adjusting the positions of the adjusting seat and the tension roller, the length of the lever arm can be changed to accommodate different tension requirements. This allows the tension roller's operating height to better match the operating height of the winding and unwinding mechanism. In operation, the swing arm is initially vertical when the machine is powered on. The servo motor provides torque to move the swing arm to the left or right. The tension shaft rotates the input shaft of the potentiometer via the coupling. The potentiometer 403 feeds back the angular position signal to the control system to adjust the unwinding speed. Because the lever arm of the tension roller assembly remains constant regardless of the swing angle, the tension transmitted to the battery electrode is stable at different positions, thus improving tension control accuracy. By adjusting the position of the tension roller assembly on the swing arm, the lever arm length can be adjusted to suit the needs of different winding and unwinding equipment, making it more versatile and practical.

[0012] (2) This utility model is equipped with tension rollers, correction ring plates and bidirectional screws. An extension plate is symmetrically fixed on the adjustment seat, and a mounting shaft seat is symmetrically installed on the extension plate. A bidirectional screw is installed on the mounting shaft seat. A knob is connected to one end of the bidirectional screw. Correction ring plates are symmetrically sleeved on both tension rollers. A second screw sleeve is fixedly installed on the correction ring plate and cooperates with the bidirectional screw. As described above, when the power battery electrode passes through the tension roller, the user can drive the bidirectional screw to rotate through the knob, so that the two sets of correction ring plates move relative to each other along the direction of the tension roller until the two sets of correction ring plates limit the two ends of the power battery electrode. Therefore, it can be used for tension control of power battery electrode with different width specifications, with a wider range of applications. It can also effectively prevent the power battery electrode from shifting and misaligning during high-speed winding, thereby preventing the electrode from shifting and misaligning and affecting the constant tension, thus increasing the difficulty of tension control.

The swing arm 8 is fixedly mounted on the tension shaft 2, and an adjusting groove 12 is provided on one side of the swing arm 8.

An adjusting seat 14 is fixedly installed on one side of the adjusting slider 20, and tension rollers 4 are symmetrically installed on the adjusting seat 14. During installation, the user can fix the device on the machine device through the mounting plate 11. Then, according to the height position of the battery electrode unwinding and winding, the adjusting motor 6 drives the adjusting lead screw 13 to rotate, thereby causing the adjusting seat 14 to drive the tension rollers 4 to move along the direction of the adjusting groove 12. By adjusting the position of the adjusting seat 14 and the tension rollers 4, the length of the lever arm used can be changed, so as to conveniently meet the adjustment needs of different tensions and make the working height of the tension rollers 4 more compatible with the working height of the unwinding and winding mechanism.

Since the force arm of the tension roller 4 assembly remains constant despite the different swing angles of the tension roller 4 assembly, the tension transmitted to the power battery electrode sheet by the tension roller 4 assembly at different positions is stable, thereby improving the tension control accuracy. By adjusting the position of the tension roller 4 assembly on the swing arm 8, the force arm length can be adjusted to suit the needs of different unwinding and winding equipment, making it more widely applicable and practical. In addition, this utility model sets... The device includes tension rollers 4, correction annular plates 5, and bidirectional lead screws 18.
