Operation 6-3
Figure 6-1 Operational Flow Chart
Production Run Started
Operator enters ECXP Command
“Start Production.”
Part Enters the System
1. If system dispense part sensor is clear, then system sends SMEMA signal
to upstream machine – “Request for Board.”
2. Stop Pin lowers.
3. When upstream machine is ready, it sends SMEMA signal to dispensing
system – “Board Ready to Send.”
4. While both SMEMA signals are high, the Conveyor indexes part toward
dispensing area.
5. Part Sensor detects part.
6. Conveyor stops.
7. Board is pinned in place
8. Dispensing system sends SMEMA signal to upstream machine – “Board
Received.”
9. Conveyor sends internal handshake signal to Dispenser – “Board at
Dispense.”
Fluid is Dispensed Onto Board
Dispensing Head moves to the locations
assigned in the current ECXP program, in
relation to the machine ori
g
in, or “Home.
”
Part Exits the System
1. Downstream machine sends “Ready to Receive” SMEMA request to
dispensing system.
2. When dispensing is finished, Dispenser sends an internal handshake
signal to Conveyor – “Dispense Done.”
3. When Conveyor receives “Dispense Done” signal, dispensing system
sends “Ready to Send” SMEMA signal to downstream machine.
4. Stop Pin and Board Pins rise.
5. Conveyor indexes until downstream machine acknowledges that part has
been received.
6. Stop Pin lowers while waiting for next part.
