This design expands the use of the IBM 7535 Robot by using the gripper to extract integrated circuit boards from a container, rotate them 90Œ, and place them into a commercial test fixture. The design provides for the correct placement of parts without an increase in cycle time. Fig. 1 shows the gripper in position over the container holding the circuit boards. The "Z" shaft 1 moves downward so that the special fingers 2, attached to a standard gripper, will grasp the end of the circuit board. A vacuum-head mounting frame 3 is attached to the standard gripper base with a bearing block 4. Attached to mounting frame 3 is the vacuum-head holder 5. A removable vacuum head 6 is attached to the head holder 5 with four screws 7 on each mounting pad 8.
