A vacuum generator is a new type of efficient, clean, economical, and small vacuum component that uses a positive pressure air source to generate negative pressure. This makes it very easy and convenient to obtain negative pressure in places where compressed air is present or where both positive and negative pressures are required in a pneumatic system. Vacuum generators are applied in fields such as machinery, electronics, packaging, printing, plastics, and robotics in industrial automation. The traditional use of vacuum generators is to use suction cups to adsorb and transport various materials, especially suitable for adsorbing fragile, soft, thin non-ferrous, non-metallic materials or spherical objects. In this type of application, a common feature is the small amount of air required, low vacuum requirements, and intermittent operation. The author believes that the analysis and research on the suction mechanism of vacuum generators and the factors affecting their working performance have practical significance for the design and selection of positive and negative pressure air paths that cannot be ignored.
Easy to wear and tear. Due to its general use of rubber and direct contact with objects, it has severe wear and tear, resulting in rapid wear and tear. It is a pneumatic vulnerable component. It is precisely because of this that the vacuum suction cup of the robotic arm stands out prominently from many pneumatic components.
No damage to the workpiece. The vacuum suction cup is made of rubber material, so it will not cause any damage to the workpiece when sucked or lowered. Hook type and steel cable type slings are not suitable. In some industries, the requirements for the surface of workpieces are particularly strict, and they can only use vacuum suction cups.
