This example uses a set of six concentric circles in which dots of white fluid are dispensed in the center of larger
black circles. A Positional Checking program is created to verify the accuracy of dot placement in relation to the
larger black circles.
Positional Checking allows the camera to determine the X and Y offset of a dispensed circle from a given or defined
location. The Step & Repeat Block command causes a window to open that shows the pass / fail status of each
dispensed dot: Green for dots that pass and red for dots that fail. The camera also takes a screen capture of each
dot and saves the image; the images provide dispense details, including diameter and XY offset.
PREREQUISITES
The system is set up to save images. Refer to “Setting Up the System to Save Images” on page9 as needed.
To learn how to use this feature, create a workpiece template with defined, circular dispense locations, similar to
the one shown below.
