[0002] A vacuum suction cup, also known as a vacuum lifting device, is one of the actuators of vacuum equipment. It is a technology that maintains the attachment of two objects without separation through vacuum degree. In industry, the "grasping" and "releasing" during handling and migration are realized by changing the vacuum degree of the suction cup, and automation and mechanization are achieved in cooperation.
