[0090] In application, after the blade blank is discharged, the pre-assembly personnel assembles the standard fixture on the blade in the pre-assembly area of the production line, and then fixes the blade assembled with the standard fixture on the blade loading vehicle until the blade loading vehicle is fully loaded. The production line control system initiates a material calling request, the factory-level MES system controls the AGV trolley to move to the pre-assembly area of the production line, lifts the blade loading vehicle, moves along the specified path to the entrance of the docking station, and stops moving and descends at the specified parking point of the docking station (in this process, the guide rollers 16 guide and pull the blade loading vehicle, and the limiting plates 18 limit the blade loading vehicle to avoid excessive movement of the blade loading vehicle). When the AGV trolley completes the descending action, the bottom side of the positioning plate 3 of the blade loading vehicle cooperates with the supporting plate 12, the AGV trolley exits the docking station, and the production line control system receives the exit signal of the AGV trolley and closes the gate of the entrance of the docking station.
