More Information about Vacuum Cups
Vacuum cups (also called suction cups) use a vacuum supply to seal against an object. One or more vacuum cups can be used depending on many factors including object weight, size, porosity, and rigidity, cup size, vacuum supply available, and movement characteristics of the vacuum cup supported load.
Vacuum cups are often used in pick-and-place applications as well as in assembly and inspection applications.
Accordion-type vacuum cups are available to allow the cup to conform to an irregular part surface, or different levels.
Vacuum cups are available in many different materials including silicone, vinyl, rubber, polyurethane, PVC, rubber, neoprene, nitrile (NBR), EPDM, and Viton.
Typical mounting styles for vacuum cups include spring mount, swivel or pivot mount, and suspension or multi-point mount. Spring-mount vacuum cups have integrally mounted springs to allow the cup to adapt to varying levels on the part. Swivel or pivot mount vacuum cups have a built-in allowance for angular surface misalignment. Large vacuum cups may use a multi-point mounting system.
Special vacuum cups are available to suit different applications, including the paper and printing industry, the bakery and food industry, the glass manufacturing industry, and the optical media industry. Optical media vacuum cups are a specialty ring vacuum cup made of non-marking silicone that is used to lift CDs, DVDs and other optical media.
Vacuum cups can only be used on non-porous materials.
