1.8 Pre-theta Movement (Station 2)
Point
Pre-theta rotates the nozzles with parts picked up at station 1 by 90°, 180° or -90°
depending on the settings in the production program.
1.8.1 Clutch Meshing Check
Perform this check on the low-pressure nozzle.
Note: The low-pressure nozzle refers to the placing head (out of the 16) that receives the weakest
pushing pressure. Use the low-pressure nozzle for meshing checks at stations 2, 8 and 10.
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. Set the dial gauge to the bottom of the nozzle shaft brake.
3. Use the cam handle to rotate the cam to 200°.
4. Ensure that the clutches mesh properly and the placing head assembly deflects the
dial gauge by 0.30 ~ 0.35 mm as illustrated below.

1.9 Fine-theta Movement (Station 8)
Point
Station 8 refers to the vision processing data at station 5 and rotates a part the remaining
angle for placement.

1.10 Nozzle Vertical Movement During Placement
(Station 9)
1.10.1 Slider Adjustment
Adjust the height of the slider to ensure that the cam follower can travel smoothly
through the slider and along the cam groove.
1. Press the EMERGENCY STOP button to take the 200V down to 100V.
WARNING
• Always be sure to cut off the 200V power before carrying
out any work.
• Exercise extreme caution when working on the machine if
the cam is not at its origin (0 deg.). Recoil of the cam
axis can endanger the operator.
2. In order to remove the nozzle shaft assembly, it is first necessary to remove the
upper clutch. Set the cam angle to zero degrees and use a spanner (DCPJ0450) to
loosen the bolt on the nozzle shaft moving from station 9 to station 10. Turn the
loosened bolt by hand and then remove the clutch. (see next page illustration)
Caution: Remove the nozzle shaft assembly which bears either a “G” or “O” identifier
seal. Operations may be complicated if other nozzle shaft assemblies are
removed.
3. Remove the linear guide clampers and vacuum hose, then remove the nozzle shaft
assembly.
Caution: When handling the nozzle shaft assembly exercise caution to ensure that the
linear guide and outer shaft do not become separated.
