​Smooth sealing surface is ideal for vacuum glass lifter operation

Smooth, sealed surface is the most ideal grasping state for vacuum glass lifter, the bonding surface is more solid, and the grasping is more convenient. The degree of suction cup and the surface of the adsorbed workpiece directly affects the vacuum pressure in the suction cup. If the degree of suction cup is too poor, the vacuum degree of the suction cup is not easy to maintain, and the purpose of adsorbing the workpiece can not be achieved. However, it is only an ideal state. Usually the surface of the captured workpiece does not have such ideal conditions. The surface of the workpiece is either porous (such as paper) or rough and uneven. These factors directly affect the degree of fit between the vacuum glass lifter and the surface of the workpiece. When the suction cup and the workpiece surface are in poor condition, the leakage phenomenon we often say will occur. There are usually two measures to remedy the leakage system:           

1.  Use high-performance vacuum generator to replenish the leaked gas in the shortest time. The disadvantage of this method is that there is still a large leakage in the system, and the energy consumption is high.           

2.  Reduce the diameter or diameter of glass lifter. The disadvantage of this method is that it can not reach the required vacuum level when the workpiece quality is large. Therefore, it is necessary to design a new type of suction cup with high adaptability for workpieces with rough surface and high quality.

Vacuum glass lifter has many advantages in use, but there are also some shortcomings. Let's learn about the characteristics of vacuum glass lifter.           
 1.  Vulnerability to wear and tear. Because it is usually made of rubber and directly touches objects, it wears badly, so it wears quickly. It is a pneumatic fragile part. It is for this reason that it is so prominently highlighted from many pneumatic components.           
 2.  Easy to use. No matter what material the object is sucked into, it can be used as long as it can be sealed and air-tight. Electromagnetic glass lifter can not  be used, it can only be used in steel, other materials of plate or object can not be absorbed.           
 3.  No damage to the workpiece. Vacuum glass lifter is made of rubber material, so it will not cause any damage to the workpiece if the workpiece is sucked or put down. However, hook-type and cable-type hangers are not feasible. In some industries, the surface requirements of workpieces are particularly stringent, they can only use vacuum glass lifters.           
 4.  No pollution. Vacuum suction cups are particularly environmentally friendly, and do not pollute the environment. There is no light, heat, electromagnetic and other generated.            

The selection of vacuum sucker should take into account the following factors:            

 1.  Buffer distance            

 2.  Shape and surface of the transferred object            

 3.  Connection Mode - Sucker, Connector, Buffer Connector            

 4.  Height of the transferred object            

 5.  The mass of the transferred object - determines the size and number of  suckers            

 6.  Working environment
