Robotic Load Mechanism for Outer Diameter Pick-up

       The illustrated tooling uses vacuum on only the outer
edge of a disk for robotic pick-up and placement.

      Fig. 1 shows the base piece 1 that mounts on the robot flange
2.  On base 1 is the gripper ends 3 and 4.  One end is used
for input and one end for output.  The disk is held as shown in the
gripper by the vacuum forces obtained, holding it in place only by
using the surface area of the non-champhered edge of the disk.

      Fig. 2 shows the gripper end 3 and 4 with the vacuum pocket 5
that acts as a vacuum chamber while slot 6 distributes the vacuum to
the edge of the disk.  The groove 7 in the gripper is made per the
characteristics dimensionally shown to eliminate the possibility of
the disk surface being touched.

      The radius of the groove 7 which matches the disk outer radius
creates the stable holding surface.  Therefore, the minimal surface
area held by the vacuum still creates the force necessary to keep the
disk held during operations.
