Application of Sponge Suction Feet

Sponge suction feet are widely used in vacuum grasping applications, such as robot palletizing and unstacking; material handling; marble, ceramic tiles, ceramic products, building materials, packaging bags, stone, wood, cardboard boxes, metal sheets. Almost all fields where vacuum grasping can be applied can use this method of grasping. Sponge suction feet have high toughness and tear resistance, and are generally used for vacuum grasping sponge sheets. There are generally black sponge rubber sheets, orange rubber sheets, and blue rubber sheets on the market now. How to use the correct materials is the key to achieving vacuum grasping. Regardless of the application of any material, the design of the suction feet itself must be considered first. The size of the suction feet opening determines the theoretical suction force of the suction plate. The flow rate selection of the vacuum generator, vacuum pump or vacuum fan needs to be determined based on the aperture size and leakage rate of the sponge suction feet. After determining the size of the sponge hole opening and the use of vacuum flow rate and vacuum degree, the suction force of the entire sponge suction feet can be easily calculated; When grasping most irregular and uneven surfaces, it is often necessary to consider the height compensation effect of the sponge and the built-in self closing valve device of the sponge suction feet (most sponge suction feet need to be equipped with self closing valve devices to adapt to grasping products of different sizes and specifications, because some suction feet surfaces that do not come into contact with the material may leak and disrupt the establishment of vacuum);

After solving the problems of sponge suction feet opening and vacuum flow rate, we can correctly build a suitable sponge vacuum suction feet system; Most occasions where sponge suction feet are used are relatively heavy work environments, and the wear and replacement of sponge pads is a challenging problem; Generally, black sponge sheets are chosen as sealing materials for situations where cardboard boxes, plastic parts, and wooden boards are grabbed; In such situations, the material is relatively soft and not easy to cause destructive tearing of the sponge rubber sheet. However, for brick and stone applications, the surface of these products is rough and uneven, with high friction. Orange and blue special sponge rubber are more suitable because the wear resistance and service life of the product are inevitable factors that affect the overall cost of using the suction feet. The application of materials is crucial. It is wise to use sponge rubber sheets of different hardness for materials of different hardness. Softer materials can be made of black sponge rubber sheets, while products with rough surfaces should choose orange special materials to enhance their wear resistance.

In short, when choosing a sponge suction feet as a vacuum fixture, it is necessary to start with the design and structure of the suction feet, including the opening of the sponge hole and whether it is equipped with a self closing valve, as well as the configuration of a vacuum pump or vacuum fan. Only by selecting the appropriate sponge material can the design and production of the suction feet be better completed. When considering the use of sponge suction feet, choosing differentiated solutions is the key to solving customers' final problems. Not all problems can be solved by using the same configuration and materials. We have rich experience in helping customers solve various difficult problems.
