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.
