LINE Mode Programming
The Advanjet software and HV-2000C controller make dispensing lines very simple. The
following examples illustrate how this is done.
Method 1: Jetting a line in PULSE mode
Click on the Timing Recipes tab, select a Recipe # and enter a
Refill
time of
1.
2 msec and
Dwell
time of 3 msec. (The timing is given here for illustration; exact
timing for fluid and pressure varies with material.)
To dispense 60 drops in the line, click on the Settings tab and set
Count
to 60
2.
and
Trigger
to PULSE.
For this example,
∆X (drop spacing) is 0.5 mm and ∆T (drop cycle time, which is
3.
Dwell time) is 5 msec/drop or 100 drops/second. To calculate the velocity
(V) of the robot:
V =
∆X / ∆T
= 0.5 mm / 0.005 sec
= 100 mm/sec
Click on Download Settings to send the new settings to the controller.
4.
The Robot makes an XY move at 100 mm/sec and issues a trigger to I/O Pin 3.
5.
The Advanjet controller will jet 60 drops at 0.5 mm spacing.
To achieve smaller drops while maintaining the same velocity and
∆X, change
6.
the Refill time to 1.7 msec and Dwell time to 3.3 msec to keep
∆T at 5 msec.
Method 2: Jetting a line in LEVEL Mode
Click on the Timing Recipes tab, select a Recipe # and enter a
Refill
time of
1.
2 msec and
Dwell
time of 3 msec. The
∆T ( Dwell time) is 5 msec.
Click on the Settings tab and set
Trigger
to LEVEL. Note: in LEVEL mode, the
2.
controller ignores the
Count
. Instead, the number of drops to dispense is
determined by the (time) duration of the 'low' trigger.
As determined above, drop cycle time (
∆T) is 5 msec. For drop spacing (∆X) of
3.
0.5 mm, robot velocity (V) is calculated as follows:
V =
∆X / ∆T
= 0.5 mm / 0.005 sec
= 100 mm/sec
Click on Download Settings to send the new settings to the controller.
4.
The Robot makes an X-Y move at 100 mm/sec and issues a trigger to I/O Pin 3.
5.
To jet 60 drops at the prescribed drop rate, this trigger signal should stay low for
300 msec (60 drops × 5 msec drop cycle time).
To dispense smaller drops at the same robot velocity and drop spacing,
6.
decrease
Refill
time to 1.7 msec and increase
Dwell
time to 3.3 msec (drop
cycle time remains at 5 msec).
