Star station 3
Reject cycle
After the gantry reaches the X and Y reject position, the valve positioning unit closes the vacuum
channel to the nozzle. Defective components are rejected from the nozzle with a short blast of
compressed air and are discarded.
Star station 7
The component is optically centered.
Star station 9
Pickup cycle
The nozzle is rotated to the pickup position.
Placement cycle
The component is rotated to the placement position (angle of rotation).
Star station 10
Sleeves can be removed here for maintenance and then reinserted.
Between star station 11&12
Option on 12 nozzle head: The presence and/or height of the component is checked before
placement.

Vacuum Generator
Placement Head Function Check
Before the 1st reference run or with released Z and star axis:
Check Z axis:
Rotate the star so that one segment is in the star pickup/place position.
Position the Z axis up and down on the belt. The LED light barrier (LB) Z up will shine (down) or
extinguish (up).
Position the Z axis downwards, touch the nozzle tip and press upwards. The LB 'Z down' will shine
and both LEDs will shine until the Z axis is pulled up again.
Check the stepping motor for swiveling in the turning station:
Touch the turning station cam disk on the right side of the head with your finger and rotate it. The 'LB
DP' LED will shine and extinguish with the scan rhythm of the cam disk.
Check the stepping motors of the valve positioning drives:
Feel along the bottom of the placement head from the right side and touch the cam disk upwards in
the pickup/place position.
3-27: Pneumatic distributor under the gantry head distributor (symbolic side
view from the right)
The placement head is supplied with 4.5 bar
compressed air from the pneumatic unit. The 7-
fold pneumatic hose is also used to cool the Y-axis
motor.
