[0002] Vacuum suction cups, also known as vacuum slings, are one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grab products is the cheapest method. There are many types of vacuum suction cups. Suction cups made of rubber can be operated at high temperatures, suction cups made of silicone rubber are very suitable for grabbing products with rough surfaces; suction cups made of polyurethane are very durable. In addition, in actual production, if the suction cup is required to be oil-resistant, you can consider using materials such as polyurethane, nitrile rubber or vinyl-containing polymers to make the suction cup. Usually, in order to avoid scratches on the surface of the product, it is best to choose a suction cup with a bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber and has a large tearing force, so it is widely used in various vacuum holding equipment.

[0003] At present, the existing vacuum suction cups are used in the food industry and the electronics industry, and a few are used in the automotive industry to transport metal sheets. However, they still have poor sealing and anti-slip performance. Due to the unreasonable structural design, the edge of the suction cup may be flipped during the transportation process.
