Why vacuum table is also called vacuum spreader
vacuum table is also called a vacuum spreader. Generally speaking, using vacuum table to grab products is the cheapest method. There are various types of vacuum tables. Rubber suction cups can be operated at high temperatures. Silicone rubber suction cups are very suitable for gripping products with rough surfaces. Suction cups made of polyurethane are very durable.
In addition, in actual production, if the suction cup is required to have oil resistance, you can consider using materials such as 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 (without clamp), 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, a pneumatic clamp can usually be installed 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.
