3.11 Vision modules
Every 6-segment and every 12-segment Collect&Place head has a separate component vision
module (see Fig. 3.7 - 3
page 118 and Fig. 3.7 - 6 page 123). The stationary P&P component vi-
sion camera (type 22) 50 x 40 is permanently fixed to the machine frame. 3

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 22) 50 x 40, and stationary component
vision camera, P&P (type 20) 8 x 8 must be removed, otherwise the Collect&Place head will col-
lide with the camera housings.
The component vision module is used to determine: 3
– 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: 3
– 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. 3
