Dispensing fluids (almost regardless of viscosity) presents unique challenges that can frustrate successful implementation in a factory floor setting. Unlike many other automation tasks, there are numerous process variables to consider. But unlike in the past, there are today tools and techniques that can help manage these variables, often in completely automated ways. With advanced software these tools can work together in a sensor/process fusion that can greatly increase part yield. This series of articles intends to look at some of these issues, their possible solutions, and the impact on the bottom line.
This first article deals with height measurement and dispense tip location and the synergy between the two sensing systems. This is a sensor mashup where the effectiveness of the mashup is much more than the sum of the individual sensor benefits.
