Welcome to All Sensors “Put the Pressure on Us” blog. This blog will bring out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities and you. This blog explores pressure required for pick and place equipment.
Pressure Required for Pick and Place Equipment
In the factory, pressure provides essential feedback for many operations. The measurement ensures both proper execution and accuracy of the process. One example is a pick and place station. In this case, a negative pressure (vacuum) lifts an object so it can be located on a work in process (WIP). If the object is not lifted for whatever reason (missing, broken, etc.), the sensor’s reading identifies an error so the WIP does not proceed to the next station. If the normal lifting pressure reduces over time due to leakage, wear or some other cause, the pressure reading can warn an operator to perform maintenance or initiate further machine diagnostics rather than have several defective operations occur.
To create the vacuum, the pump requires energy and time to build to the right pneumatic level. It also takes time to empty the pick and place tool when it has to release the object. These factors all lead to a pump and operating point selection. Typical operating levels will vary based on the application and can range from low to high PSI pressures.
Do you have a pressure sensing question?
Let me know and I’ll address it in an upcoming blog.
