Abstract

Substrates are moved throughout the manufacturing line in product carriers. The Robotic Gripper described provides a dual function of holding the carrier in place, while the substrate is removed. The carrier hold-down force is required because the substrate is locked in place by pressure clamp tabs. The Robotic Gripper and push bar are activated by compressed air. Referring to Figs. 1 and 2, the Robotic Gripper functions as follows: (1) Lower the Robotic Gripper 3 over the rack 1. (2) Air on to cylinder 10 to close fingers 4. (Image Omitted), (3) Vacuum port 6 on cylinder 9 to retain substrates 5. (4) Raise Robotic Gripper 3 and compressed air on to gripper 3 and to finger cylinders 8, thereby activating the two pushbars to force rack 1 away from gripper assembly 3.

, (3) Vacuum port 6 on cylinder 9

to retain substrates 5.
(4) Raise Robotic Gripper 3 and compressed air on to gripper

3 and to finger cylinders 8, thereby activating the two

pushbars to force rack 1 away from gripper assembly 3.
(5) Then air to fingers 4 off when clear of rack 1.
(6) Reposition substrates (controller for robot).
(7) Vacuum off (vacuum ports 6).
(8) Air on to cylinder 10, to open fingers 4.
(9) Return to original position, or to the next

substrate to be removed.
