The automatic placement system is a high-performance placement system with four gantry
axis systems. A PCB vision system and a star-shaped 12-segment revolver head are mounted
on each gantry. Revolver placement heads equipped with a component vision system pick up
the components from stationary feeder modules and insert them into the PCB clamped in the
PCB conveyor.

The concept behind the automatic placement system
– with its stationary feeder modules,
– PCBs that do not move during placement
– and positionable placement heads
has a number of significant benefits:
– For example, the flexible 12-segment revolver heads combined with automatic nozzle
changers enable the nozzle configuration to be changed temporarily and automatically
adapted to receive different component sizes. You can also optimize the traversing paths
and the placement sequence.
– With stationary feeder modules, even the tiniest components are picked up reliably.
– The components cannot slip on the PCB during placement (as is often the case with mov-
ing PCBs) since the PCB does not move.
– Sophisticated optical centering systems (vision systems) for components and PCBs also
ensure high component positioning accuracy.
– Components can be topped up and tapes can be spliced without stopping the machine.
– Prepared component tables enable the placement system to be retooled without long stop-
pages.
