Why vacuum table is also called vacuum spreader





  The alias of vacuum table is also called vacuum spreader. It is a very cheap method to use vacuum table to grab products. There are many varieties of vacuum tables. Suction cups made of rubber can generally be operated at high temperatures. Suction cups made of silicone rubber are very suitable for gripping products with rough surfaces.

       In addition, in actual production, if the suction cup has oil resistance, you can consider using polyurethane, nitrile rubber or vinyl-containing polymers to make the suction cup. Generally, in order to avoid scratches on the surface of the product, it is best to choose a suction cup with a bellows made of nitrile rubber or silicone rubber.
   In the case of EOAT using vacuum table, it should be noted that the moving speed of the manipulator should not be too high, otherwise a shear force will be generated on the suction cup, making the product easy to fall off during the rapid twisting process. In some cases, a clamp can be used to ensure safe transportation of products. Considering that the product may stick to the mold, it is generally necessary to install an air clamp to solve this problem. When the surface area of ​​the product is too small or the product is too heavy to use the vacuum table, this problem can also be solved by using clamps.
