3.8 Vision system
3.8.1 Structure
A component camera is integrated into each Collect&Place head (see Fig. 3.5 - 2 page 108 and
Fig. 3.5 - 4
page 112). The stationary P&P component vision camera (type 33) 55 x 45 digital for
the TwinHead is permanently 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 the placement head is changed from the TwinHead to the Collect&Place head, the Twin-
Head's stationary component vision camera, P&P (type 33) 55 x 45, and stationary P&P compo-
nent vision camera (type 25) 16 x 16 digital must be removed, otherwise the Collect&Place head
will collide with the camera housings.
