Characteristics and Applications of Vacuum Suction Cups

Vacuum suction cups, also known as vacuum lifters, are one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grasp products is the most cost-effective method. There are various types of vacuum suction cups, and the suction cup materials are made of nitrile rubber, which has a high tear strength.

Working principle of vacuum suction cups

The air port is connected to the vacuum generator. When the vacuum generator is activated, the air port is ventilated, and the air inside the suction cup is drawn out, forming a vacuum state with pressure P2. At this time, the air pressure inside the suction cup is lower than the atmospheric pressure P1 outside the suction cup, i.e., P2<P1. The workpiece is sucked up under the external pressure. The higher the vacuum inside the suction cup, the tighter the suction cup sticks to the workpiece.

Characteristics of vacuum suction cups

High load capacity

Usually, when professional vacuum suction cups are designed, the load-bearing requirements are considered: their surfaces are designed to be corrugated to increase the friction and adsorption capacity with smooth and non-air-permeable workpieces, ensuring they can withstand large objects several times their own weight during operation.

Ease of use

No matter what material the object being sucked is made of, as long as it can be sealed and does not leak air, vacuum suction cups can be used. Electromagnetic suction cups cannot; they can only be used on steel, and cannot suck plates or objects made of other materials.

More environmentally friendly

Since the materials used for vacuum suction cups are usually silicone rubber or nitrile rubber, and these materials do not contain toxic or harmful substances, they are relatively environmentally friendly. They are not easily released toxic or harmful gases during use, preventing pollution to workpieces. They also do not produce substances like light, heat, or electromagnetic interference that could pollute the environment.

Non-damaging to workpieces

Since the materials usually used in vacuum suction cups are rubber, they do not cause damage to workpieces during suction and release, making them suitable for various precision equipment manufacturing processes.

Application fields of vacuum suction cups

Automation field

In the field of automation, suction cups are a common device used to pick up materials, transfer workpieces, or perform gripping operations. Different suction cup designs are suited for different materials and workpieces, such as steel plates, glass plates, ceramic pieces, plastic products, etc.

Robotics field

In parts processing, suction cups can secure workpieces onto the processing platform to maintain processing quality and precision. In the field of robotics, vacuum suction cups can be used as end effectors of robots to play the role of gripping and transporting objects, enabling robots to accurately complete assembly tasks.

Logistics and warehousing field

In logistics, warehousing, and assembly fields, robots equipped with vacuum suction cups can achieve automated handling and assembly, improving production efficiency and accuracy.

In summary, vacuum suction cups generate suction through creating a vacuum environment and utilizing air pressure difference to grasp and transport various objects. Their working principle is efficient and practical, with extensive application fields, playing an important role in automation production lines, warehousing logistics, robotics, and other fields, significantly improving production efficiency and operational safety.
