Gripper changing device

Abstract

This invention discloses a gripper replacement device. The gripper replacement device includes grippers, a support platform, an adjustment component, and a drive component. In this invention, when replacing the grippers of an AMR (Automatic Mechanism for Removing and Replacing a Memory Module), the gripper mounting structure moves the original gripper to a corresponding position above the placement structure. The drive component controls the gripper to gradually approach the connecting post, causing the pressing surface to press against the connecting post, thus loosening the connection between the original gripper and the gripper mounting structure, and the original gripper falls onto the placement structure. Then, the gripper mounting structure moves above the placement structure where the new gripper is placed and moves down to mate with the new gripper. Next, the drive component, through the adjustment component, moves the gripper closer to the connection point between the new gripper and the gripper mounting structure until the pressing surface presses against the connecting post, ensuring full engagement between the new gripper and the gripper mounting structure. Finally, the gripper disengages from the connecting post, completing the connection between the new gripper and the gripper mounting structure, ultimately achieving rapid gripper replacement and improving wafer handling efficiency.

Claims
