Vibration type suction cup

Abstract

The vibration type suction cup comprises a pulse electromagnetic valve, a vacuum connector and a suction cup body, the pulse electromagnetic valve comprises a valve body, a valve rod, a valve element, a locking screw and a reset spring, a magnetic induction channel is formed in the valve body, and the top end of the valve rod is fixed in the magnetic induction channel through the locking screw; a first air channel penetrating in the axial direction of the locking screw is formed in the locking screw, the valve element is movably installed in the valve rod, a second air channel penetrating in the axial direction of the valve element is formed in the valve element, a frustum part and a second spring limiting part are arranged on the top of the valve element in a protruding mode, and a conical concave part and a first spring limiting part are arranged at the bottom of the locking screw in a concave mode. The reset spring is installed between the first spring limiting part and the second spring limiting part. The sucking disc is driven by the pulse electromagnetic valve to vibrate quickly, and is matched with vacuum adsorption and an elastic mechanism, so that high-frequency up-and-down movement after film materials are sucked can be realized, only one film material is sucked at a time, and the problems that a plurality of film materials are easy to adhere and overlap and are inconvenient to take and use are solved.
