Selection and Configuration of Vacuum Suction cups

- May 20, 2019-

What is the weight and size of the workpiece?


How is the surface finish of the workpiece (rough, meshy, smooth)


How clean is the workpiece surface? What pollutants are there?


What is the highest temperature of the workpiece?


Does it need to be precisely positioned to grasp or place the workpiece?


How long is the cycle?


What is the maximum acceleration during handling?


How about the mode of handling (moving, rotating, flipping)?


What are the environmental impacts?


Important Basis for Calculating Suction Force and Suction Cup Number


Choose the type of sucker (material, shape, size)


The Important Basis for Determining the Size of Sucker and Designing Dust Filter


The important basis for selecting the material of the sucker is that the special material should be used when the temperature is higher than 70 degrees.


Determine the structure, type and shape of sucker
