1. An automated polishing system, comprising:

  • a workbench;

    a transport unit provided with a transport surface and a transport drive configured to drive the transport surface to move horizontally;

    two polishing units fixed on the workbench arranged in order along a moving direction of the transport surface and separated from each other, each of the two polishing units including;

    (i) a supporting portion, a holding arm rotatably connected to the supporting portion, and a holder rotatably connected to the holding arm for holding an object to be polished;

    (ii) a horizontal drive configured to drive the supporting portion to move horizontally, a vertical drive configured to drive the supporting portion to move vertically, a horizontally rotating drive configured to drive the holding arm to rotate in a horizontal direction, a vertically rotating drive configured to drive the holder to rotate about a hinged connection with the holding arm in a vertical direction to make a surface of the object to be polished face towards a polishing shaft, and a rotating drive configured to drive the holder to rotate relative to the holding arm; and

    (iii) a polishing rotating device configured to drive the polishing shaft, and a polishing drive configured to drive the polishing shaft to move towards the holder for reciprocating motion;

    a control unit connected to the transport drive, the polishing rotating device, the polishing drive, the horizontal drive, the vertical drive, the horizontally rotating drive, the vertically rotating drive and the rotating drive; and

    a turnover unit located between the two polishing units in a horizontal direction, wherein the turnover unit is provided with two connecting parts and two guide rails which are fixed on the workbench through the connecting parts respectively, arranged above the transport surface, and separated from each other, and one end of each guide rail at the same end is curved upwards from a plane where the guide rails are located, so that the guide rails are in a shape of a diminishing curve along the moving direction of the transport surface.
