8.3.7 Picking Up the First Component
Fig. 8.3 - 7 Picking up the first component
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.
Note: All Vacuum measurements during the placement process are making in the background
and don‘t produce an error messages. The error messages about missing components or somth-
ing like that, will produce only from the component sensor.
8.3.8 Picking Up the 10th Component
Fig. 8.3 - 8 Picking up the 10th component
Star position 0°
– Vision system: no action
– Pick up / placement station: pick up first
component
– Z-axis downwards
– Vacuum check for component pickup
– Component sensor: direct measurement
after picking up the first component (ap-
plies accordingly to all other segments)
– Vacuum check after pickup: check holding
force of the component on the nozzle.

– Vision system: prepare SIPLACE Vision
for optical centering.
– Pickup/placement station:
pick up the 10th component
–
A : The components previously picked up
are rotated to the centering angle. (center-
ing angle [0°, 90°, 180°, 270°] = place-
ment angle in 90° steps)
– Measurement of hold circuit for segment 1
(output to measuring sensor)

– Vision system: optical centering of the 10th comp.
– Pickup/placement station:
pick up the 20th component.
– Communication with the component table:
cutter enabled
– Synchronization: after picking up the 20th compo-
