[0002] In the daily medical work of hospitals, various medical tools are applied to different departments, including but not limited to, for example: reusable endoscope instruments, basic surgical instruments, lumen instruments, orthopedic instruments, anesthesia instruments, dental handpieces, ophthalmic instruments and other instruments. During the cleaning process, a cleaning rack for placing these medical tools will be involved. To improve the overall operation efficiency of medical treatment, in the reprocessing link of these medical tools, the cleaning rack loaded with medical tools is automatically transported by an automated device, replacing manual transportation, saving manpower, and running fully automatically, improving the transportation efficiency. The existing transmission of the cleaning rack is usually roller transmission through the AGV conveying method. During the transportation process, the cleaning rack is mainly limited on the AGV by the friction force between the AGV roller and the cleaning rack. There are the following problems: 1. During the transmission process of the rolling roller, the loading capacity of the cleaning rack is different, and the smoothness of the transmission is different. Sometimes, if the cleaning rack runs off during the transmission process, the rolling roller will rotate while the cleaning rack does not move. 2. There is no blocking mechanism on the AGV. During the operation of the AGV, the cleaning rack may slide out of the AGV, causing the instruments to fall and be damaged. Therefore, it is necessary to optimize the design of the existing transmission device of the cleaning rack to achieve smoother and more stable operation. Content of the Utility Model
