Disk Transfer Gripper for Robots

A disk transfer gripper for robots, is shown in Fig. 1, which will allow both inside diameter (ID) and outside diameter (OD) disk pickup.

The tool is divided into two separate portions by function.

Portion 1 is the vacuum ID pickup. It is of rigid design which aligns the surface of the disk to the surface of the tool. The outer surface of the disk rests against the lip 9 in the tool, assuring parallelism between the tool and the disk, while also assuring that there will be a good vacuum seal. The vacuum is applied through a circular groove 10 in the tool's surface which seals at the ID to retain the disk. The tool is of a plastic material which is selected to prevent damage to the disk surfaces.

Tool portion 2 is the mechanical OD pickup. This requires the tool to move into the edge of the disk until the slot in the tool touches the OD. At this point the motor 1 activates cam 2, which in turn moves finger 3, trapping the disk by the ID into the slot 4 in the tool. The disk is then raised from the container. Using arms 5, which are activated by air cylinder 6 to clamp the OD of the disk between the jaws 7, the finger 3 is then retracted permitting the disk to be held only by the OD.
