The Vacuum suction cup connects the vacuum generator to the workpiece and plays a crucial role in designing every vacuum handling system.
1. A wide range of options
2. Various materials, different applications
3. Various temperature resistance classes
4. Perfect adhesion even with edges and angles
5. Vacuum chuck function
A suction cup is a gripper that can handle various weights, shapes, surfaces, and sizes. Vacuum suction cups can manipulate objects of all shapes, sizes, and materials if selected correctly.
Vacuum suction cups can hold, lift or rotate almost any kind of material during the production process. The suction cups are gentle in their contact with the object being handled and will not damage the object being handled, making the technology very simple and safe.
The main types of vacuum suction cups include
Flat suction cups without anti-slip nails
These suction cups are generally used for handling flat or slightly round, smooth, and stiff objects. They can withstand lateral forces and can therefore be used for vertical handling.
Flat suction cups with non-slip spikes
These vacuum suction cups are generally used for handling thin, deformable, and flexible objects. They increase the resistance to lateral forces and horizontal handling.
Suction cups with bellows
These are generally used to handle spherical, egg-shaped, or cylindrical objects, and the influence of technical characteristics generally increases with the number of bellows. They can be used to grip objects with height differences and spherical joint effects; thus, corners or edges can be gripped.
Choosing the right material
Which material is suitable for your vacuum pump system? Depending on the actual situation, vacuum suction cups are generally made of different composite materials. Each has different abrasion resistance, deformability, temperature extremes, tearing, and chemical properties, so materials will include
1. Polyurethane – very resistant to oil
2. Butadiene rubber – antistatic properties
3. Nitrile rubber – low cost and versatile
4. Silicone and synthetic rubber fluoropolymer elastomers (Viton) – high-temperature resistance
Choose the right size.
Regardless of which brand of vacuum suction cup you choose, it would help if you used the giant vacuum suction cup possible to reduce the demands on your vacuum pump system.
The vacuum suction cups’ size, number, style, and material can be selected based on the following factors.
1. Size of the object to be handled
2. weight
3. orientation
4. surface temperature
5. condition
6. Space available for mounting cups
Vacuum cup suction force and speed calculation
Vacuum cups must accommodate inclined, round, irregular, and curved surfaces. Hence, selecting the most suitable type of vacuum cup for a specific need is fundamental.
The suction cup selection generally depends on specific conditions, such as the surface quality and structural stability of the part to be lifted and the desired material and shape of the suction cup. However, a simplified formula can be used to generate theoretical estimates based on some known values.
Using a larger vacuum chuck, heavier objects can be manipulated using the same pressure. Conversely, a smaller vacuum chuck generally requires a higher vacuum to lift the same object. Keeping the pressure low helps to ensure a longer service life. It reduces the energy requirement since the vacuum force and the energy required to generate that force do not show a linear relationship.
F = P X A
F = weight of the object in pounds or grams
P = desired vacuum level in PSI or MPa
A = effective area of the vacuum chuck measured in in2 or mm2 (the effective area will be different from the area calculated directly from the actual chuck diameter. Please refer to the manufacturer’s documentation)
