3.10 Vision modules
3.10.1 Description
Each placement system has
– two component vision cameras on the placement heads and
– two PCB vision cameras on the underside of the X-axis gantries.
The vision analysis unit is located in the control unit for the placement system. 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 camera uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB vision camera also uses fiducials on the feeders to determine the exact pick-up posi-
tion of components. This is particularly important for small components.
