Operation 5-5
Figure 5-2 Operational Flow Chart
Production Run Started
Operator enters ECXP Command
“Start Production.”
Part Enters the System
1. If system 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 coating
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. Coating System sends SMEMA signal to upstream machine – “Board
Received.”
9. Conveyor sends internal handshake signal to coating system – “Board at
Dispense.”
Conformal Coating is Applied
Robot moves to the locations assigned in
the current ECXP program, in relation to
the machine origin, or “Home.”
Part Exits the System
1. Downstream machine sends “Ready to Receive” SMEMA request to
dispensing system.
2. When coating is finished, coating system sends an internal handshake
signal to conveyor – “Coating Done.”
3. When conveyor receives “Coating Done” signal, coating 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.
