Operation 4-3
Fluid is Dispensed onto Board
Dispensor moves to the locations assigned
in the current FmNT program, in relation to
the machine origin, or "Home"
Part Exits the System
1. Downstream machine sends "Ready to Receive" SMEMA
request to Asymtek
2. When dispensing is finished, Dispensor sends an internal
handshake signal to Conveyor: "Dispense Done"
3. When Conveyor receives "Dispense Done" signal, Asymtek
sends "Ready to Send" SMEMA signal to downstream machine
4. Dispense Zone stop pin and clamp bars drop
5. Conveyor indexes until downstream machine acknowledges that
part has been received
6. Dispense Zone stop pin rises again while waiting for next part
Production Run Started
Operator enters FMW Command--
"Run Production"
Part Moves from Pre-Dispense to Dispense Zone
If Dispense Zone is empty...
1. Dispense Zone stop pin rises
2. Pre-Dispense stop pin drops
3. Conveyor indexes part toward Dispense Zone
4. Dispense Zone part sensor detects part
5. Conveyor stops
6. Conveyor clamp bar rises
7. If equipped, Under Board Support lifts into place.
8. Conveyor sends internal handshake signal to
Dispensor, "Board at Dispense"
Part Enters the System
1. If Asymtek's Pre-Dispense part sensor is clear, then
Asymtek sends SMEMA signal to upstream machine--
"Request for Board"
2. Pre-Dispense Zone stop pins rise
3. When upstream machine is ready, it sends SMEMA signal to
Asymtek--"Board Ready to Send"
4. While both SMEMA signals are high, the conveyor indexes
part toward Pre-Dispense Zone
5. Pre-Dispense part sensor detects part
6. Conveyor stops
7. Asymtek sends SMEMA signal to upstream machine--"Board
Received"
