7.4.5 Turning Nozzles 1 to 20 to the Pickup Angle (0° or 90°)
7.4.6 Checking the Nozzle Length for Component Recognition
7-22: Turning segments 1 to 20 to the pickup angle (0° or 90°)
The segments in the C&P20A head are turned
in succession, from segment 1 to 20, to the
required pickup angle of 0° or 90°.
NOTE:
Each segment has its own DP drive
7-23: 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.

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.
7.4.8 Picking Up component 11
7-24: 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.
NOTE:
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.
7-25: Picking Up component 11
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 centering angle.
(centering angle [0°, 90°, 180°, 270°] =
placement angle in 90° steps)
Measurement of hold circuit for Segment 1

7.4.9 Picking Up component 11
7.4.10 Picking Up Component 12
7-26: Picking Up component 11
Star position 180°
Vision system: Optical centering of component
on segment 1.
Pickup/placement station: Pick up component
11
A : The components previously picked up are
rotated to the centering angle. Empty nozzles
are turned to the next pickup angle.
Measurement of hold circuit for segment 2
7-27: Picking up component 11
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 centering angle, here.
B : The components are adjusted to their
placement angles.
