Description

Technical Field

[0002] The working principle of the suction cup used by the robot is: the suction cup is adsorbed on the surface of the workpiece, and the workpiece is transported by a highly flexible special fixture through proximity sensors, programmable logic controllers, etc. to form an automated end picking and transportation system for the workpiece. The suction cup is an important component and consumable part of the end picker. Since the suction cup itself cannot be fixed, a connecting component needs to be set to connect it to the end picker arm. Traditional vacuum suction cups require a complete seal to successfully adsorb. The working efficiency of a single suction cup cannot be guaranteed, which in turn affects the production speed of the production line. In addition, the vacuum suction cup will become loose after long-term use, which is prone to safety hazards. Utility Model Content
