Abstract
A gripper mounted on a robot is used in a smart factory to pick a door loaded on a pallet. The gripper includes: a frame mounted on a tool changer of the robot; a picking unit mounted on a front of the frame and applying pressure to and regulating each of upper and lower points of an opening formed in an inner panel of the door through a bundle pin locator; and a pressure control valve adjusting the pressure of guide air cylinders. The gripper further includes: a side clamping unit mounted on the frame and holding a side point of the opening by a fixing locator and a clamper operating with a driving force of a clamping cylinder; and a control unit adjusting a moving distance of the robot based on a distance difference between the side clamping unit and the inner panel.
