2.2.15.1 Steps when picking up and placing components
– A PCB moves into the placement area of the PCB conveyor.
– After the fiducial measurement the C&P head picks up components from the feeder moduls.
– The components are measured below the component camera and turned in the Dp station into
the correct placement angle position.
– In the star station 1 the component will be placed.
2.2.15.2 Position and function of the individual star stations (see Fig. 2.2 - 24)
Star station 1 2
Pick-up cycle
The nozzle is lowered onto the component. Once the valve positioning unit has opened the vac-
uum circuit to the nozzle, the nozzle sucks the component and removes it from the feeder module.
Placement cycle
The valve positioning unit closes the vacuum channel to the nozzle. The nozzle, together with the
component, is lowered onto the PCB that has been moved into place. A short burst of compressed
air detaches the component from the nozzle and places it on the PCB.
Reject cycle
The valve positioning unit closes the vacuum channel to the nozzle. Defective components are
detached and discarded from the nozzle with a short burst of compressed air.
Star station 3 (only use for the HS60 and S27 HM machine) 2
Note:
The HF machine don‘t use the stepper motor in the reject position, because the reject position now
is the same as the pick up and placment position.
Star station 7 2
The component is optically centered.
Star station 9 2
Pick-up cycle
The nozzle is rotated to the pick-up position.
Placement cycle
The component is turned to the correct placement angle.

2.2.15.4 Nozzle changer for 12 segment C&P head
The Siplace HF is supplied as standard with one 6 segment or one 12 segment collect&place
head. As an option, a nozzle changer can be installed for each collect&place head. This enables
the nozzle configuration to be changed quickly, thus allowing the collect&place head to be quickly
adapted to the needs of the placement process.
The nozzle changer consists of at least one, and up to ten magazines, each with twelve nozzle
garages (see Fig. 2.2 - 25). The magazines are seated on a common support and each magazine
is centered using two parallel pins and fixed in place with a spring hook.
Optionally can you configure each garage with a different nozzle type.
