Medicine trays are sequentially placed on the shelves of the profile frame, and medicine storage baskets are placed on the medicine trays. The medicine trays to be retrieved are placed on the lifting platform frame. A servo motor and a drive motor are installed inside the lifting platform. The servo motor drives a transmission shaft through a first synchronous pulley. An active synchronous pulley is installed at the end of the transmission shaft and is used to drive the lifting action. The active synchronous pulley is located inside the lifting synchronous belt. A tray proximity switch is installed on the profile frame above the medicine tray. The drive motor is driven by the synchronous belt, and the synchronous pulleys inside the synchronous belt are coaxially mounted on bearing seats. The lifting platform has tray support plates and slide rails on both sides.

[0012] Furthermore, chains and roller hooks are provided on both sides of the drive shaft, and a fixing block is provided below the tray at the chain.

[0013] Furthermore, tray stop blocks and tray plastic sliders are provided on both sides of the medicine tray.
