[0022] 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.

[0023] Example 1

[0024] Please see Figures 1 to 3 This utility model provides a technical solution: a lithium battery processing and winding device, including a fixed base 1 and a winding roller 2, and also includes a pressure sensor 3, a spring 4, a connecting frame 5, a pressing roller 6 and a connecting rod 7;

[0025] Pressure sensor 3 is installed on the inner top of the fixed base 1 to monitor pressure changes in real time;

[0026] One end of the spring 4 is connected to the pressure sensor 3, and the other end of the spring 4 is connected to the connecting bracket 5. The pressure signal is transmitted through the deformation of the spring 4.

[0027] There are two connecting rods 7, one end of which is connected to the connecting frame 5 to form a lifting guide structure;

[0028] The clamping roller 6 is rotatably connected inside the connecting frame 5, and the clamping roller 6 is located at the top of the winding roller 2. The clamping roller 6 is used to clamp the lithium battery wound by the winding roller 2. The clamping roller 6 slides upward along the connecting rod 7 as the winding diameter increases.

[0029] A clamping groove 21 is provided on the outer side of the connecting frame 5. Limiting rods 8 are installed at the top of both connecting rods 7, located on the top of the fixed base 1. An electric push rod 9 is installed on one side of the top of the fixed base 1. A clamping plate 10 is installed at the telescopic end of the electric push rod 9, and the clamping plate 10 is adapted to the clamping groove 21. Several sets of anti-slip rubber particles are provided on the outer side of the clamping plate 10. A mounting frame 11 is installed on the outer side of the fixed base 1. A motor 12 is installed on the inner side of the mounting frame 11. The power drive end of the motor 12 is connected to a connecting cylinder 13. The inner side of the fixed base 1... The unit is equipped with an electric push rod 2 14, and a rotating seat 15 is installed at the telescopic end of the electric push rod 2 14. A connecting cylinder 2 16 is connected inside the rotating seat 15. Both the connecting cylinder 1 13 and the connecting cylinder 2 16 have cross slots 17 inside. Both sides of the outer side of the take-up roller 2 are equipped with cross insert plates 18, which are adapted to the cross slots 17. The connecting cylinder 2 16 is connected inside the rotating seat 15. A connecting groove 19 is opened on one side of the interior of the fixed seat 1. The connecting cylinder 1 13 is connected inside the connecting groove 19. A central processing unit 20 is installed inside the fixed seat 1.

[0030] The pressure roller 6 is located at the top of the take-up roller 2, the spring 4 is in a naturally extended state, and the pressure sensor 3 monitors the initial pressure (close to zero). The cross plates 18 at both ends of the take-up roller 2 are inserted into the cross slots 17 opened in the connecting cylinder 13 and the connecting cylinder 2 16, respectively, and the electric push rod 2 14 is in the extended state to fix the position of the take-up roller 2. Through the linkage between the pressure sensor 3 and the central processing unit 20, the winding diameter is calculated in real time, and the operator is alerted when the diameter exceeds or falls below the preset range to ensure product quality. After winding is completed, the pressure plate 10 automatically locks the pressure roller 6, making it easy to disengage the take-up roller 2 and improve production efficiency. The elastic coefficient of the spring 4 matches the winding pressure range to avoid damage to the sensor due to over-range. The symmetrically arranged connecting rods 7 restrict the connecting frame 5 to move only in the vertical direction, eliminating the risk of lateral offset, ensuring the axial parallelism of the pressure roller 6 and the take-up roller 2, and reducing winding misalignment.

[0031] During the winding operation, the cross plates 18 at both ends of the winding roller 2 are inserted into the cross slots 17 opened in the connecting cylinder 13 and the connecting cylinder 2 16, respectively. At this time, the motor 12 starts and drives the winding roller 2 to rotate through the connecting cylinder 13. The connecting cylinder 2 16 rotates in the rotating seat 15. The lithium battery material begins to be wound on the surface of the winding roller 2. As the winding diameter increases, the pressure roller 6 slides upward along the connecting rod 7 to compress the spring 4. The pressure sensor 3 monitors the reaction force (pressure force) of the spring 4 in real time and converts the pressure signal into an electrical signal and transmits it to the central processing unit 20.

[0032] When the winding diameter reaches the set pressure value range, the central processing unit 20 reminds the staff of the current diameter status through an audible and visual alarm or display screen; when the winding diameter reaches the target value, the motor 12 stops, and the central processing unit 20 triggers the winding end signal; at this time, the electric push rod 9 extends and pushes the pressure plate 10 down into the pressure groove 21 of the connecting frame 5, and increases the friction through the anti-slip rubber particles, locking the position of the pressure roller 6 to prevent the winding material from springing back.

[0033] Example 2

[0034] In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that when the take-up roller 2 needs to be detached, the central processing unit 20 controls the electric push rod 2 14 to retract, driving the rotating seat 15 and the connecting cylinder 2 16 to move backward. Through manual intervention, the cross plates 18 on both sides of the take-up roller 2 are disengaged from the cross slots 17. The operator can easily remove the finished take-up roller 2 and install a new empty take-up roller 2, repeating the above process.
