7.4.7 Picking Up Component 1
The remaining nozzles now pick up the components as the star is stepped and turn these into the correct
centering angle, before they reach the component camera.
Checking the nozzle length ("component recognition by
component sensor before placement")
Component sensor measures at star pickup position:
▪ Vacuum measurement: ’Segment open’ value
▪ The component sensor measures the length of the
nozzle. The measured length before pickup is verified
with the reference length.
▪ If a difference of -0.15 mm or +0.1 mm is found, the
gantry axes will move the placement head into the
service position for replacement of the nozzle.
▪ Measurement is performed "on the fly" in the star
pickup/placement position.
Picking up component 1
Star position 0°
▪ Vision system: No action
▪ Pickup/placement station: Picking up component 1
▪ Z Axis Down
▪ Vacuum check for component pickup
▪ Component sensor: direct measurement after picking
up the first component (applies accordingly to all
other segments)
▪ Vacuum check after pickup: Check holding force of
the component on the nozzle.
NOTICE
All vacuum measurements during the placement process are performed in the background and
do not produce any error messages. The error messages concerning missing components etc.
are produced only by the component sensor.

Picking up component 10
Star position 162°
▪ Vision system: "Prepare SIPLACE Vision for optical
centering".
▪ Pickup/placement station: Pick up component 10
▪ A : The components previously picked up are rotated
to the placement angle.
(centering angle [0°, 90°, 180°, 270°] = placement
angle in 90° steps)
▪ Measurement of hold circuit for Segment 1 (output to
measuring sensor)
Picking up component 11
Star position 180°
▪ Vision system: Optical centering of component on
segment 1.
▪ Pickup/placement station: Picking Up Component 11
▪ A : The components previously picked up are rotated
to the placement angle. Empty nozzles are turned to
the next pickup angle.
▪ Measurement of hold circuit for segment 2

Picking up component 12
Star position 198°
▪ Vision system: Component at segment 2 of this
gantry is centered
▪ Pickup/placement station: Picking Up Component 12
▪ A : The components previously picked up are rotated
to the placement angle.
▪ B : The components are adjusted to their placement
angles.
Picking up component 13
Star position 216°
▪ Vision system: Optical centering of component 3
▪ Pickup/placement station: Picking Up Component 13
▪ A : The components previously picked up are rotated
to the placement angle.
▪ B : The components are adjusted to their placement
angles.
▪ Measurement of holding circuit for segment 4
The process continues with the remaining components:
picked up, centered and turned to the correct or corrected
placement angle.
