Theory of Operation (Continued)
3. Typically, FmNT performs the following functions:
Coordinates the motions of the conveyor with upstream machines.
Moves the workpiece on the conveyor into the dispense station.
Moves the dispense head until the camera finds a fiducial mark on the
workpiece.
Moves the dispense head until the camera finds a second fiducial mark on
the workpiece (optional).
Calculates the rotation of the workpiece, using the measured positions of
the fiducials.
Moves the dispense valve over a pre-programmed position on the
workpiece.
Instructs the valve to dispense a pre-programmed pattern of fluid on to a
workpiece.
After dispense, moves the workpiece toward the downstream end of the
conveyor.
Coordinates the motions of the conveyor with downstream machines.
E. Theory of Operation
1. Typically, dispensing processes involve each of the critical operations listed
below:
Programming and initializing Fluidmove for Windows NT software
Loading and unloading of the part
Heating of the part in one or all of the heating zones: Pre-dispense zone,
dispense zone and post-dispense zone
Fluid control (heating, pumping)
Dispensing process control (Dispensing Head control)
2. The way in which each operation is accomplished may vary depending upon
system configuration.
