Abstract: Proposed is a universal gripping and suction chuck for use as an interchangeable end effector of a robot arm of a robotic station capable of picking up, transporting, and handling objects having colors and outlines. The chuck housing contains elements of a vacuum system for holding the object by vacuum suction force, a vortex system for holding the objects in a non-contact manner in a state of levitation, and a mechanical edge gripper. The vacuum system, the vortex system, and the mechanical edge gripper can be selectively activated by commands from the central processing system that receives a signal recognition signal, object presence/absence signal and/or object approaching signal from respective sensors and depending on the type of the object recognized by the respective sensor. As a result, the chuck can pick up and handle such different objects as solid semiconductor wafer, paper or fabric interleaves, or small-diameter rings.

Abstract: Two-phase gripper. The gripper reorients and grasps an object while being picked up. The gripper includes a parallel jaw gripper including a pair of opposed, two-phase fingers, each finger including a cavity covered by an elastic strip wherein the elastic strip includes a point contact. Closure of the jaws of the gripper on an object at a first relatively lower force results in contact with lower friction between the point contact on the elastic strip on the fingers and the object allowing the object to rotate under gravity as the gripper is raised. Thereafter, closure of the jaws of the gripper on the object at a second relatively higher force causes the elastic strip to receded into the cavity resulting in multi-point contact with higher friction between the fingers and the object to securely grasp the object. In a preferred embodiment, the cavity is a Y-shaped groove and the object is cylindrical or prismatic.
