Abstract

This utility model discloses an industrial robot composite gripper, including a robot connector body, a connecting plate rotatably connected to the bottom end of the robot connector body, and two symmetrically arranged clamping plates slidably connected inside the connecting plate. Each clamping plate has a movable groove inside, and a movable plate is slidably connected inside each movable groove. Each clamping plate is equipped with a drive mechanism for driving the movable plate to rise and fall within the clamping plate. This industrial robot composite gripper, through the drive mechanism, drives the movable plate to rise and fall within the clamping plate, thereby driving the workpiece to rise and fall. This allows the device as a whole to better place the precision parts being clamped, avoiding excessively long or fast movement of the gripper, which could cause the precision parts to shift during placement. It also effectively grips densely packed precision parts, thus improving the overall gripping efficiency of the device.
