When the fourth motor 26 is started, the rotating platform 25 is driven to rotate by the rotation of the output shaft of the fourth motor 26, so that the lithium battery on the surface of the rotating platform 25 can follow the rotation, and the angle of the lithium battery can be adjusted. The rotating platform 25 cooperates with the lifting and reversing integrated device to mark the side of the lithium battery. The height of the fixed baffle 3 is relatively low, and will not interfere with the operation of the marking mechanism 9 and the angle adjustment of the beam 6, thereby improving the working flexibility.

[0024] Furthermore, the adjustable clamping mechanism includes a support plate 10, which is fixedly connected to the side of the marking workbench 1.

The third motor 15 drives the first gear 16 to rotate through the rotation of the output shaft, and drives the second gear 19 to rotate through the meshing of the first gear 16 and the second gear 19, thereby driving the second transmission shaft 23 to rotate. The rotation of the second transmission shaft 23 drives the first pulley 18 to rotate, and the meshing of the first pulley 18 and the belt 17 drives the belt 17 to rotate. Since the other end of the belt 17 away from the first pulley 18 is meshed with the second pulley 21, the second pulley 21 is driven to rotate.

The sensor 13 detects the position of the lithium battery, and the second hydraulic cylinder 11 and the sensor 13 work together to achieve the clamping of the lithium battery.

[0029] Furthermore, the control cabinet sends a start command to the first hydraulic cylinder 2. The first hydraulic cylinder 2 moves up and down according to the position determined by the detection of the sensor 13. The feeding box 8 is also provided with a sensor 13. Through the detection of the sensor 13, the first hydraulic cylinder 2 is adjusted to rise or fall to an appropriate height.

[0030] Furthermore, the control cabinet sends a start command to the second motor 7. The rotation of the second motor 7 drives the clockwise or counterclockwise rotation of the feeding box 8 through the rotation of the output shaft, thereby adjusting the angle of the marking mechanism 9. The sensor on the feeding box 8 detects the surface of the battery, which facilitates the marking mechanism 9 to mark the surface of the lithium battery.
