This height is reduced by 1.23 mm and saved for the actual contactless pickup height.
Default pickup sequence
:Start gantry axes to the pick up position next feeder & communication to component table:
start signal to Gantry axes
Next feeder signal / this opens feeder flap
end signal X-, Y-, Star-axis:
end signal Star-axis
Vacuum check: Segment sealed? before pick up
X / Y end signals existing
Z-Axis starts:
Z-axis starts positioning downward in absolute positioning mode.
light barrier (LB) above :
enables LB bottom but this is not activated
Axis controller trigger:
end signal positioning Z-axis downwards
Machine controller switch with end signal positioning Z-axis down:
- valve drive to vacuum
6.3.29.1 Advantage of special mode "contactless pick up"
This "contactless pick up" offer you:
no touch to the component feed module and therefor no movement of components - no jump-
ing of components at pick up area.
increased pickup reliability for very light and easy "jumping" components. The nozzle float ap-
proximately 0.1 mm above the component and suck it out of the component pocket.
No delay compared to the standard pickup cycle.
No additional polution in the head.
No restriction on feeder or component types. The nozzle have to have only enough suction
force for the component.
The first component from the learning sequence is rejected to the reject bin (SC/MC 505 or
patched SC/MC-version).

Fig. 6.3 - 27 Placing component detailed: Z-axis downwards with light barrier mode
The placement force is defined by the spring in the sleeve ~2.4 N at 12 nozzle head
End signal X-, Y-, Star-axis:
all 3 end signal available
vacuum check before placement is executed (alternatively the component check in the
comp.sensor).
component on the nozzle?
Z-axis starts:
Z-axis positioning downward
LB above switches:
solenoid air kiss ON
enable LB bottom
LB bottom switches:
End signal positioning downward;
valve drive, pick up- placement position, to air kiss

6.3.31 Placing component detailed: Z-axis upwards
Fig. 6.3 - 28 Placing component detailed: Z-axis upwards
LB bottom switch:
End signal positioning downward; valve drive, pick up- placement position, to air kiss;
Measure air kiss pressure component placed
Start term to move up
Z-axis started:
Z-axis positioning upwards
LB above:
reset solenoid for air kiss
reset LB bottom signal
enable start for gantry axes
Z-axis end signal (Z-axis on 0-position):
(503) vacuum check after placement
enable start for Star-axis
