3.2.7.1 Overview of Functions for Star Stations 1 - 12
3.2.7.2 Position and Function of the Individual Star Stations
Star station 1:
Pick-up cycle
The nozzle is lowered towards the component. After a vacuum has been produced with the help of
the valve positioning function, the nozzle takes the component from the feeder module.
Placement cycle
The nozzle, together with the component, is lowered onto the PCB that has been moved into place.
The valve is positioned to cut off the supply of vacuum to the nozzle. A brief burst of air separates
the component from the nozzle and the component is placed onto the board.
Star station 3:
Reject cycle
The valve is positioned to cut off the supply of vacuum to the nozzle. Defective components are
rejected from the nozzle with a short air kiss of compressed air and are discarded.
Star station 7:
The component is optically centered.
Star station 9:
Pick-up cycle
The nozzle is rotated into the "pickup" position.
Placement cycle
The component is rotated into the correct placement angle with the help of the DP axis.
Star station 1: pickup, placement
Star station 2: no function
Star station 3: reject component
Star station 4-6: no function
Star station 7: optical centering of component
Star station 8: no function
Star station 9: rotate component
Star station 10: service position for sleeves and
nozzles
Star station 11 and 12: no function (optional
component sensor)

Between star station 11&12
The "presence" and "height" of the component at the nozzle is checked by the CO sensor (optional).
3.2.7.3 Component Pickup and Placement
X A board is moved into the placement area of the PCB conveyor and is clamped into place.
X After fiducial measurement, the Collect&Place head picks up the components from the feeder
modules.
X The components are measured under the CO camera and rotated into the correct position in the DP
station.
X The component is placed in star station 1.
3.2.7.4 Nozzle changer for 12 segment C&P head
Optionally, a nozzle changer can be installed for each C&P 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 five magazines, each of which is equipped with
up to twelve nozzle garages. The magazines are seated on a common support and each magazine is
centered using two pins and is fixed in place with a spring hook.
Each garage can be configured with different nozzle types.
