After the commutation mechanism 300 completes commutation, the commutation mechanism 300 conveys the optical fiber ferrules to the transfer mechanism 500. Then, the transfer mechanism 500 conveys the optical fiber ferrules to the PC grinding mechanism 200. After the PC grinding mechanism 200 finishes grinding, the PC grinding mechanism 200 can convey the optical fiber ferrules to the discharging assembly 560 of the transfer mechanism 500 for discharging, such as conveying the optical fiber ferrules from the PC grinding mechanism 200 into the discharging tray 561 of the discharging assembly 560, thereby completing the automatic continuous grinding of the optical fiber ferrules.

[0086] In this embodiment, the vibrating disk 600 can convey the optical fiber ferrule to the ferrule loading tooling 470 through a hose. Then, the first Y-axis moving member 420 can drive the suction nozzle 410 to descend and pick up the optical fiber ferrule. The suction nozzle 410 is driven by the first X-axis moving member 430 to drive the optical fiber ferrule above the loading V-groove 440. Then, the first Y-axis moving member 420 can drive the suction nozzle 410 to descend and release the optical fiber ferrule into the loading V-groove 440. The stepping motor 492 can drive the loading V-groove 440 to move, so that the optical fiber ferrule on the loading V-groove 440 is located below the detection camera 493. Then, the detection camera 493 takes a picture of the optical fiber ferrule for detection and identifies the direction of the optical fiber ferrule.
