The vacuum pad selection method is shown below.
1) Taking the balance of the workpiece carefully into account, determine the adsorption position, the number of pads, and the available pad dimensions (or area of the pads).
2) Determine the theoretical lifting force from the adsorption area (pad area x number of pads) and the vacuum pressure, and then determine the required lifting force considering the safety factor according to the actual lifting method and moving conditions.
3) Compare the weight of the workpiece and the lifting force to determine the pad diameter (pad area) required (lifting force > workpiece weight).
4) Determine the required shape and material of the pad and whether a buffer is needed based on the conditions of use and the shape and material of the workpiece.
5) Vacuum pads are not designed for vacuum retention.
6) Perform a suction test on the actual device to determine whether it can be used or not.
Note) This is the general procedure for selecting a vacuum pad, however, it does not apply to all types of vacuum pads.
Ultimately, testing using the actual device is the best way to determine whether a pad is ideal for the application.
