Patent ID: 7478601

Claim:
A robotic turntable comprising: a motor; a first table rotationally driven by the motor; a workpiece table mechanically coupled to the first table wherein the workpiece table is rotatable with the first table to maintain a rotational position of the workpiece table with respect to the first table and the workpiece table is rotatable with respect to the first table to change the rotational position of the workpiece table with respect to the first table and the workpiece table is tiltable to a first tilt and to a second tilt with respect to the first table; a first actuator having a first actuating member moveable between a free position and a stop position, wherein while the first actuating member is in the free position the first actuating member does not affect rotation of the workpiece table thereby allowing the workpiece table to rotate with the first table and while the first actuating member is in the stop position the first actuating member prevents the workpiece table from rotating with respect to the first table thereby changing the rotational position of the workpiece table with respect to the first table; and a second actuator having a second actuating member moveable between a second free position and a second stop position, wherein while the second actuating member is in the second free position the second actuating member does not contact rotatable elements of the robotic turntable, and while the second actuating member is in the second stop position, the rotation of the first table is coupled to a change in tilt of the workpiece table.
