1.14 Overview of the modules - vision modules
Each placement system has 1
– 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 and the component
vision module is used to determine: 1
– 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: 1
– the position of the PCB,
– its rotation angle
– and the PCB delay.
The PCB vision module also uses fiducials on the feeder modules to determine the exact pick-up
position of components, which is particularly important for small components. 1
