6.14 Light barriers and stopper for scanning the PCB
positions along the transport routes
6.14.1 Function
The positions of the PCBs are scanned with the help of light barriers (transmitter and receiver
modules). The light barriers are installed above the conveyor belt and feel along the length of the
conveyor belt.
The light barrier signal stops the PCBs on the input conveyor, intermediate conveyor (HS-60 only)
and output conveyors. The light barrier in the placement area can be moved 50 mm against the
direction of transport to guarantee secure positioning of the PCB.
In the placement area the light barrier triggers the braking procedure via a DC motor. The soft-
ware regulates a constant time interval for the slow travel towards the laser light barrier.
