3.8 Vision system
3.8.1 Structure
A component camera is integrated at each Collect&Place head (see fig. 3.5 - 2 page 112 and fig.
3.5 - 4
page 117). 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 3
When changing the placement head from TwinStar to SpeedStar, the stationary component cam-
eras of type 33, 55 x 45, digital, and type 25, 16 x 16, digital (FC camera) need to be dismantled
from the TwinStar, otherwise the SpeedStar will collide with the camera housing.
When changing the placement head from TwinStar to MultiStar, the stationary component cam-
era, type 33, 55 x 45, digital, is fitted in the bottom position.
