9.3.4 Preparations for Component Pickup (Module 2)
Legend
1. Z motor
2. Vacuum/air blast generator
When Vacuum threshold ‘Pick up’ is measured
the Z Axis movement upwards start with
Standard-positioning mode.
Communication to component trolley ‘index
feeder’ when the Z axis reaches 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).
The next pickup sequence is prepared for a
module 2 component.
Legend
1. Z motor
2. D motor
Pick up with module 1 finished
The X and Y gantry axes move to the feeder
track or pickup position.
During gantry positioning, the module 2 D-axis
rotates to the pickup angle.
Communication to component trolley ‘Feeder
ready’ opens feeder pickup window.

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.

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.
