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.
