3.8 Vision system
3.8.1 Structure
A component camera is integrated at each Collect&Place head (see fig. 3.5 - 2 page 107 and fig.
3.5 - 4
page 112). The component camera, stationary, P&P (type 33) 55 x 45, digital, for the Mul-
tiStar and the TwinStar is fixed to the machine frame.
The component vision module is used to determine:
– the precise position of the components at the nozzle and
– the geometry of the package form.
The PCB vision module uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB cameras are fixed to the bottom of the gantries. They use fiducials on the feeder mod-
ules to determine the exact pick-up position of components, which is particularly important for
small components.

WARNING
Risk of head crash!
When changing the placement head from a TwinStar/VHF to a SpeedStar, the SpeedStar
collides with the camera housing.
Dismantle the stationary component cameras of type 33, 55 x 45, and type 25, 16 x
16 digital (FC camera) for the TwinStar.
When changing the placement head from TwinStar to MultiStar, the stationary component
camera, type 33, 55 x 45, digital, is fitted in the bottom position.
