9.3.4.1 Picking up the Component (Module 2)
Legend
1. Z motor
2. Vacuum/air blast generator
3. Force sensor
Z Axis position downwards with Standard Pick
up mode at 2 N Pick up force.
At contact with the component the force
increase up to the programmed value.
At this force level the End signal is triggered
and the Vacuum controlling is activated.

When Vacuum threshold ‘Pick up’ is measured
the Z Axis movement upwards start with
Standard-positioning mode.
Communication to comp. table ‘index Feeder’
when the Z Axis reached the "safety height"
position.
At end signal Z Axis top -> Vacuum check
‘comp. on nozzle’
The D-axis is rotated to the placement angle
(so that only the component correction angle
needs to be rotated after centering).
Prepare optical centering with module 1

9.3.5 Component centering module 1 and 2
9.3.6 Preparations for Placement (Module 1 Component)
X/Y axes position module 1 via the IC camera.
Start Z Axis to move Bottom side of comp. to
focus level.
‘flash’ IC-camera illumination
Move Z Axis again upwards.
centering 1st component (near placement
angle) is finished
The X/Y axes position module 2 over the IC
camera.
Start Z Axis to move Bottom side of comp. to
focus level.
‘flash’ IC-camera illumination
Move Z Axis again upwards.
The X/Y gantry axes move to the corrected
placement position.
The D-axis rotates by the placement angle
correction value.

9.3.6.1 Placement (Module 1 Component)
9.3.7 Preparations for Placement (Module 2 Component)
The Z axis moves downwards in standard
mode (2 N contact force).
The Force increase up to the programmed
level after contact of the component on the
PCB.
With this Force signal the End signal is set.
The air blast control is activated too.
At air blast level for placement ..
The next placement sequence is prepared for
a module 2 component.
The X/Y gantry axes moves to the actual
(corrected) placement position.
The D-axis rotates by the placement angle
correction value.
