Table 7-1 Dispensing System Operational Sequence
Operational Step Details
1. A workpiece enters the Axiom
X-1020 Dispensing System.
a. The dispensing system communicates with the upstream
machine via the SMEMA connection signaling that it is ready
to accept a workpiece.
b. The upstream machine receives the signal as an input.
c. If the upstream machine is ready to send a workpiece, it
responds with an output signal back to the dispensing
system.
d. The dispensing system receives the signal from the upstream
machine as an input.
e. The Conveyor Controller determines if the pairs of inputs and
outputs indicate that the workpiece can be conveyed into the
dispensing chamber.
> If the dispensing process requires the workpiece to be
preheated, the workpiece is conveyed to the
Pre-dispense Station, go to Step 2.
> If the dispensing process does not require queuing or
preheating, the workpiece is conveyed directly to the
Dispense Station, skip to Step 4.
f.
2. The workpiece is conveyed
into the Pre-dispense Station.
a. A Stop Pin is engaged to stop workpiece transport.
b. A Board Sensor detects the workpiece.
c. The Lift Table rises to hold the workpiece in place.
d. Pre-dispense Station Heater Tooling, set at a programmed
temperature, heats the workpiece. The workpiece remains at
the Pre-dispense Station for a pre-programmed period of
time.
3. The workpiece leaves the
Pre-dispense Station.
a. The Stop Pin disengages, the Lift Table lowers, and the
workpiece is conveyed to the Dispense Station.
4. The workpiece arrives at the
Dispense Station.
a. A Stop Pin is engaged to stop workpiece transport.
b. A Board Sensor detects the workpiece.
c. The Lift Table rises to hold the workpiece in place during the
dispensing process.
d. The workpiece is heated, or temperature is maintained, by
Dispense Station Heater Tooling.
