[0035] Reference Figure 1 and Figure 3 The auxiliary cleaning station 4 includes a base 41, a water storage tank 42, a cleaning nozzle 43, a circulating conveyor belt 44 and a plurality of water suction rollers 45. In this embodiment, a foundation pit for the base 41 to be installed can be formed on the workshop floor, so that the surface of the base 41 is flush with the ground, and the circulating conveyor belt 44 is installed on the base 41. The circulating conveyor belt 44 includes a power motor 441, a belt 442 and two guide rollers 443. The two guide rollers 443 are both rotatably installed on the base 41 through bearings. The two guide rollers 443 are arranged at intervals along the length direction of the base 41. The two ends of the belt 442 are respectively tensioned on the two guide rollers 443. At the same time, the power motor 441 is installed On the base 41, the output end of the power motor 441 is connected to the end of one of the guide rollers 443; when the AGV wheel self-cleaning device is ready to clean the wheel, the power motor 441 is started, and its output end begins to rotate, driving a guide roller 443 connected to it to rotate. Since this guide roller 443 is tightly connected to the belt 442, and the other end of the belt 442 is also tensioned on another guide roller 443, the belt 442 begins to circulate with the rotation of the guide roller 443, and the AGV wheel slowly presses onto the circulating conveyor belt 44. Driven by the belt 442, the wheel begins to move forward and enters the cleaning area.

[0036] Reference Figure 1 and Figure 3A water tank 42 is installed inside the base 41. In this embodiment, detergent or clean water can be stored in the water tank 42. A cleaning nozzle 43 is installed on the surface of the base 41. In this embodiment, there are multiple groups of cleaning nozzles 43, and the multiple groups of cleaning nozzles 43 are symmetrically arranged on both sides of the width direction of the belt 442. Each cleaning nozzle 43 is installed with a water pipe 5. One end of the water pipe 5 is connected to the cleaning nozzle 43, and the other end of the water pipe 5 is connected to the water tank 42.

The surface of the water absorption roller 45 is slightly higher than the upper surface of the base 41, and the water absorption roller 45 is wrapped with a water absorption cotton layer 451; when the wet cleaning is completed, the AGV wheel enters the dry mopping area, and the AGV wheel contacts the water absorption roller 45 during driving. The water absorption roller 45 absorbs the residual water on the wheel through rotation and friction to prevent the residual water from causing watermarks. It can quickly absorb the residual water on the wheel, shorten the drying time, improve the cleaning efficiency, effectively prevent the generation of watermarks, maintain the cleanliness and beauty of the wheel surface, and reduce the slippery phenomenon of the ground.

[0038] The implementation principle of an AGV wheel self-cleaning device in an embodiment of the present application is as follows: when cleaning the AGV wheel, after the AGV trolley 1 reaches the designated position and the AGV trolley 1 stops steadily, the AGV wheel slowly presses onto the circulating conveyor belt 44, and the circulating conveyor belt 44 starts to run at a set speed, driving the wheel to move forward, and at the same time the cleaning nozzle 43 is started, and the cleaning nozzle 43 extracts the cleaning liquid in the water tank 42 through the water pipe 5, and sprays the cleaning liquid (which may be clean water mixed with an appropriate amount of detergent) onto the circulating conveyor belt 44 and the wheel surface, deeply cleaning the wheel surface to remove attached dirt and marks, and after completing the wet cleaning, the AGV wheel enters the dry mopping area, and the AGV wheel contacts the water absorption roller 45 during driving, and the water absorption roller 45 absorbs the residual water on the wheel through rotation and friction to prevent residual water from forming watermarks, and exits the auxiliary cleaning station 4 after confirming that it is dry;

[0039] During the daily operation of the AGV wheel, the wheel cleaning brush 31 lightly touches the wheel surface to brush off the dust and foreign matter attached to the wheel surface. It can also brush off foreign matter stuck on the wheel to prevent the foreign matter from being rolled into the vehicle chassis. The wheel cleaning brush 31 works continuously to keep the wheel surface clean.

[0040] By setting up the on-board cleaning unit 3 and the auxiliary cleaning station 4, the surface of the AGV wheel can be deeply cleaned. The cleaning liquid can be evenly sprayed on the wheel to effectively remove the attached dirt and marks, ensuring that every part of the wheel can be fully cleaned without leaving any dead corners. Without the need for direct manual operation, the automatic management of the cleaning process can be achieved, which can effectively deal with the problem of wheel marks on floors of different materials, reduce the wear and tear on the floor, and thus extend the service life of the floor.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
