Fig. 8.3 - 11 Picking up the 13th component
The process continues with the remaining components being picked up, centred and turned to the
correct or corrected placement angle.

– Pickup/placement station:
pick up the 20th component.
– Communication with the component table:
cutter enabled
– Synchronization: after picking up the 20th compo-
nent, this gantry waits for positioning enable from
the other Y-axis controller
– Component sensor:
During the next star step, component presence/
height check is performed for segment 1.

Star turns to -> 360° (identical with 0° position)
When the star axis has turned to 360.000 digits, seg-
ment 1 is again in star-placement position.
– Vacuum check: holding force for component avai
lable?
– Z- axis starts to move downwards and then
– The component sensor checks the presence or
the height of the component at segment 1.
– The measured length before placement must be
larger than "nozzle length + comp.height - comp.
height tol."
– If errors occur, the Z-axis will be stopped and mo -
ved back.

(marked red (light grey) here)
– At the next step Visionsystem have to center opti-
cally the component at segment 1 on the other gan-
try. (marked blue here)
– Component sensor:
Checks before placement; if component is present
on nozzle / after placement; if the component has
been placed.
