Vacuum sucker, also known as vacuum spreader, is one of the vacuum equipment actuators. In general, the use of vacuum suction cup grabbing products is the cheapest method.Vacuum suckers are of various kinds. Rubber suckers can be operated at high temperature. Silicone suckers are very suitable for grasping products with rough surface.Suction cups made from polyurethane are durable. In addition, in the actual production, if the suction cup is required to be oil-resistant, it may be considered to use materials such as polyurethane, nitrile butadiene rubber, or polymers containing vinyl to make the suction cup.Generally, in order to avoid the surface of the product is scratched, the best choice is made of nitrile rubber or silicone rubber with bellow suction cup material is made of nitrile rubber, has a greater tearing force, so it is widely used in various vacuum suction equipment.
The working principle of the flat vacuum chuck is shown in the figure.First, connect the vacuum suction cup with vacuum equipment (such as vacuum generator, not shown in the picture) through the connection, and then contact with the vacuum equipment to be lifted, such as glass, paper, etc., start vacuum equipment suction, so as to generate negative air pressure in the suction cup, so that the suction to be lifted firmly, you can begin to move and deliver the vacuum equipment to be lifted.When the lifting object is to be delivered to the destination, it will be steadily inflated into the vacuum sucker, making the vacuum sucker change from negative pressure to zero pressure or slightly positive pressure, and the vacuum sucker will leave the lifting object, thus completing the task of lifting and lifting heavy objects.
