3.9 Overview of the modules - vision modules
Each placement system has
– four component vision modules on the placement heads and
– four PCB vision modules on the underside of the X axis gantries.
The vision analysis units are 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 module uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB vision module also uses fiducials on the feeder modules to determine the exact pick-up
position of components. This is particularly important for small components.
