Pick and Place Probe Checking the Probe Tip

Pick and Place Probe
The workspace Pick and Place head (PNP head) has one probe which
requires periodic maintenance. The headings below describe
maintenance.
Checking the Probe Tip
A worn or damaged probe tip on the PNP head can cause dropped devices
and placement problems.
1. Check the probe tip for cracks or tears. If necessary, replace with a
probe tip of the same size.
2. Test the probe tip—
2a. At the Setup window, click System > Gantry.
2b. Click the Vacuum switch to ON.
2c. Open the safety door and place a device on the target probe.
2d. If the vacuum does not firmly hold the device, replace the
probe tip with a probe tip of the same size.
CHECKING THE PROBE
Check that the probe is not loose. Tighten the set screw on the stem if
necessary. If you suspect or hear an air leak:
1. Remove the set screw on the probe
stem.
2. Pull off the probe stem and check
the O-Ring. Replace if necessary.
3. Reassemble.
CLEANING THE PROBE TIP
To clean the Probe tip:
1. Move the PNP head to a convenient
position by clicking one of the
yellow labels on the Gantry
window. The Tool position is
recommended.
2. Open the safety door.
3. Wipe the tip with alcohol wipes
(Data I/O PN 570-0410-001) or a
damp cloth.

Note: Do not touch the probe tip with bare hands. Finger oils can cause
small devices to stick.
Adjusting Probe Blow-Off Pressure
Note: The flow controls are set at the factory and should not require
adjustment. If adjustments need to be made, they should be done in small
steps until the desired results are reached.
Blow-off is a small puff of air applied at the probe during the device drop
event to assist in removing a device from the probe. Blow-off is produced
by a vacuum generator on the PNP head. If set too high, blow-off could
cause device misalignment during placement.
TOOLS REQUIRED
• Large flat screwdriver
• Very small flat screwdriver
To adjust blow-off pressure on any vacuum generator:
1. Click System > Misc. I/O.
2. At the I/O Interface window, select the desired vacuum generator,
probe 1 or probe 2 (or both).
3. Click Vacuum to the OFF position. Refer to Figure 4-4.
4. Click Blow-off to the ON position.

WARNING: Possible collision hazard! The high speed and force of
the gantry can seriously harm anyone working inside the

workspace.
When working within the machine workspace, moving the PNP head must
be the responsibility of only one qualified individual. All others must stay
clear of the machine controls to prevent injury to that person.
Ensure that a job is Paused or Finished, or the system power is OFF prior to
opening any safety doors.
5. Locate the actual vacuum generator (Data I/O PN 815-0047-001) on
the right side of the PNP head. Find the blow-off adjustment
set-screw. It is inside a long knurled stem which needs to be
loosened before adjusting the set-screw. See the figure below.
Figure 61: The Blow-off adjustment set-screw on the vacuum
generator is inside a knurled locking stem (arrow). (The vacuum
block must NOT be removed as shown here.)
6. Turn the adjustment screw until the vacuum generator readout
displays +1.5 to 2.0 kPa.
7. While holding the set screw with the screwdriver, tighten the knurled
stem.
8. Do the same for the other probe.
9. Click Blow-off to the OFF position.
If you had a blow-off problem, test your results.
Adjusting the Vacuum Generator Sensor
Note: If you notice consecutive programming pick errors, before adjusting
vacuum sensors complete the Z-Axis adjustment. For instructions on Z-Axis
adjustment, see Teaching the Workspace Locations on page
