The vacuum chuck is the most common part of the vacuum system. In addition, because the rubber material of the suction nozzle material needs to be replaced for a long time, the suction cup belongs to the vacuum system. In use, the bet of the suction cup contacts the surface of the workpiece to form a closed space, which causes the suction cup and maintains a pressure difference, and then sucks and grabs the workpiece. . The suction connection end is usually connected by a metal structure and a hose of the vacuum system to form a vacuum.

The selection of supporting suction cups often needs to consider the overall structure of the pumping and accessories. Suction accessories and fixed and spring type interfaces with vertical and vertical hardware; the suction cup itself is divided into flat suction cups, corrugated suction cups and some special suction cups, which are used on different workpiece surfaces. The vacuum suction cups of different materials are used in different environments. One of the actuators of vacuum suction cup vacuum equipment, the suction cup material is made of nitrile rubber, which has a large tensile stress, so it is widely used in various types of vacuum suction equipment.

In the past few years, vacuum technology has been greatly improved in the world. The monopoly of the mechanical clamping device used in the field with the vacuum chuck surface material, center of gravity and other conditions depending on the mechanical clamping device has been broken. Compared with mechanical fixtures, vacuum chucks have advantages in some applications. First, it is more efficient. Since the mechanical clamping tool avoids a series of grasping actions, the speed and speed of the vacuum chuck have been greatly improved. And reducing the time period of the action can be more perfect for the speed requirements of the new high-speed production line. Secondly, good flexibility. Compared with mechanical fixtures, tools greatly improve the flexibility of vacuum suction cups, such as large-area LCD panels. If you use mechanical clamping tools, it is completely impossible to grasp it. Again, the material is not easily damaged. Due to the need for firm clamping, the mechanical clamping tool will always exert greater power on the object being grasped, so there is a risk of damaging the object. The vacuum suction cup is absorbed on the surface and will not cause damage to the object.
