The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1-3, the invention discloses an automatic glass bead loading device for a hub, which comprises a glass bead loading assembly and a material moving assembly.
The glass bead feeding assembly comprises a vibration hopper 20 and a rotary bearing tray 21, a plurality of accommodating grooves 22 are uniformly formed in the upper side of the bearing tray 21 around the axis of the bearing tray, and a discharge port of the vibration hopper 20 is in butt joint with the accommodating grooves 22. The vibratory hopper 20 continuously outputs the glass balls. Since the discharge port of the vibration hopper 20 is butted against the housing groove 22. Since the plurality of accommodating grooves 22 are provided, when the accommodating groove 22 abutting against the guide rail of the vibration hopper 20 is filled with glass beads, the support tray 21 is rotated so that the accommodating groove 22 of the next hole abuts against the vibration hopper 20, and then the glass beads in the vibration tray enter the empty accommodating groove 22. Thus, as the tray 21 rotates, the plurality of glass beads can be loaded on the tray 21. For the rotation of the support plate 21 a motor drive can be used.
Referring to fig. 2, the transfer assembly includes a first multi-axis robot 30, a mounting plate 31, and a plurality of suction cups 32. A first lifting driving source is arranged between the mounting plate 31 and the suction cup 32, and the first lifting driving source drives the suction cup 32 to move up and down to grab the glass beads in the accommodating groove 22. The plurality of suction cups 32 are uniformly arranged around the center of the mounting plate 31. Since the accommodating grooves 22 of the supporting plate 21 are filled with glass beads, when the number of the sucking discs 32 is the same as that of the accommodating grooves 22, each sucking disc 32 corresponds to one accommodating groove 22, and the sucking discs 32 can simultaneously grab the glass beads on the supporting plate 21. When the number of the suction cups 32 is different from the number of the receiving grooves 22, the mounting plate 31 rotates so that each suction cup 32 sequentially grasps the glass beads, thereby completing the grasping of the glass beads.
