Vacuum suction cups have many advantages in use, but there are also some shortcomings. Let's take a look at the characteristics of vacuum chucks:
First, no pollution. The vacuum suction cup is especially environmentally friendly, does not pollute the environment, and has no light, heat or electromagnetic.
Second, easy to use. No matter what material the object is made of, it can be used as long as it can be sealed without leaking. Electromagnetic suction cup can't be used. They can only be used on steel. Plates or objects of other materials cannot be sucked.
Third, do not hurt the workpiece. Since the vacuum suction is made of a rubber material, sucking or lowering the workpiece does not cause any damage to the workpiece. Hook-type spreaders and wire-type spreaders do not work. In some industries, the surface requirements of the workpiece are particularly strict, they can only use vacuum suction cups.
Fourth, easy to wear. Since it is generally made of rubber, it is in direct contact with the object, and the wear is severe, so the loss is fast. It is a pneumatic wearing part. For this reason, it has become so prominently highlighted from many pneumatic components.
The selection of vacuum chucks should take into account the following factors:
1 The quality of the object being transferred – determines the size and number of suction cups.
2 Shape and surface condition of the object being transported – the type of suction cup selected.
3 Working environment (temperature) – select the material of the suction cup.
4 connection method – suction cup, connector, buffer connector.
5 The height of the object being transferred.
6 buffer distance.
