The robot arm 1 is arranged on one side of the loading device 2. The loading device 2 includes a first storage cabinet 21 and a second storage cabinet 22. The first storage cabinet 21 is arranged on one side of the second storage cabinet 22. The tops of the first storage cabinet 21 and the second storage cabinet 22 are both provided with discharge holes. The interiors of the first storage cabinet 21 and the second storage cabinet 22 are both provided with automatic feeders 3. The automatic feeder 3 includes a rotating shaft 31, a conveyor belt 32 and a servo motor 33. The surface of the conveyor belt 32 is evenly and evenly provided with a plurality of accommodating grooves. The servo motor 33 is provided with a plurality of accommodating grooves. The motor 33 is arranged at the inner top of the first storage cabinet 21, and the rotating shaft 31 is connected to the output shaft of the servo motor 33 through the coupling 4. The rotating shaft 31 is located below the discharge hole. Discs 5 are sleeved on both ends of the rotating shaft 31, and magnets 6 are arranged inside the discs 5. Multiple accommodating holes are evenly arranged axially on the discs 5. A clamping claw is arranged at the end of the robot arm 1, and a first clamping module, a second clamping module and a rotating disk are arranged on the clamping claw. The first clamping module and the second clamping module are symmetrically arranged on the rotating disk. Cabinet doors are arranged on one side of the first storage cabinet 21 and the second storage cabinet 22, and the cabinet doors are fixed by magnetic attraction.

[0024] like Figure 1-Figure 3As shown, a placement rack 7 is provided on one side of the bottom of the robot arm 1, a conveyor 8 is provided on the top of the placement rack 7, a blowing device 9 is provided on the conveyor 8, the blowing device 9 includes a blower 91, a connecting hose 92 and a nozzle 93, the nozzle 93 is connected to the blower 91 through the connecting hose 92, an elastic paddle is provided inside the nozzle 93, an infrared alignment device is provided on the rotating disk, and an infrared positioning point is provided on the outer side of the first storage cabinet 21.

[0025] Specific implementation process: through the receiving hole of the disc, the shaft parts transported by the conveyor belt can be adsorbed on the rotating shaft with the cooperation of the electromagnet. The receiving groove on the conveyor belt can prevent the shaft parts from rolling during transportation, and one receiving groove corresponds to one shaft part, making the transportation of parts more orderly. In this way, the parts can be automatically loaded, and then the automatic and precise positioning of loading and unloading can be achieved through the cooperation of the robot arm, thereby improving the processing efficiency and processing accuracy of the shaft parts and avoiding the effect of low yield rate caused by insufficient processing accuracy. Because the disc contains magnets 6, the conveyor belt 32 is directly adsorbed by the disc when transporting the shaft parts to the top of the storage cabinet. However, because the contact position between the periphery of the disc and the shaft parts is point contact, it will not be directly adsorbed. When the shaft parts are located in the solute groove of the disc, the suction force of the magnet can stably adsorb the shaft parts on the disc, thereby achieving the adsorption and positioning of the shaft parts.
