Vacuum grippers are devices that use suction to lift and move objects. They typically consist of a suction cup connected to a vacuum pump. When the pump creates a vacuum, air pressure outside the cup holds the object securely in place, allowing for safe transport without damaging the item. These grippers are commonly used in manufacturing and automation to handle various materials, such as glass, metal, and plastic. Their ability to adapt to different shapes and sizes makes them versatile tools in robotics and assembly lines, improving efficiency and reducing manual labor.
