1.17 Overview of the modules - vision modules
Each placement system has 1
– four component vision cameras on the placement heads and
– four PCB vision cameras on the underside of the X-axis gantries.
The vision evaluation units are located in the control unit for the placement system and the com-
ponent 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

1.18.1 Structure of the PCB conveyor
The placement system is supplied with a single conveyor as standard. A dual conveyor is avail-
able as an option. 1
The left or the right side of the PCB conveyor can be used as the stationary side, as required. 1
