[0028] In this embodiment, a mounting plate 201 is fixedly installed on the output end of the collaborative robot 2, a suction cup 203 is fixedly installed on one end of the mounting plate 201, and a connecting port of the suction cup 203 is connected to the air inlet of the vacuum pump. The spherical workpiece 10 can be picked up and placed by the set suction cup 203.

[0029] In the embodiment, two groups of circular feeding practice units 3 are provided, and the two groups of circular feeding practice units 3 are both used to provide spherical workpieces 10. The spherical workpieces 10 provided by the two circular feeding practice units 3 are of different colors. The circular feeding practice units 3 include a circular silo 301 and a material table 305. The circular silo 301 and the material table 305 are both fixedly installed on the working platform 101. A feeding port 302 is provided on the top of the circular silo 301, and a DC reduction motor 303 is fixedly installed on one side of the circular silo 301. A lever is provided inside the circular silo 301, and one end of the lever is fixedly connected to the rotating shaft of the DC reduction motor 303.
