1.5.1 Functional description

The automatic placement system is a high-performance placement system with two 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 compo-

nents from stationary feeder modules and place them onto the PCB clamped in the PCB conveyor.1

1.5 Description of the machine Software Version SR.405.xx 05/99 Issue

The concept behind the automatic placement system 1

– with its stationary feeder modules,

– PCBs that do not move during placement

– and positionable placement heads

has a number of significant benefits: 1

– For example, the flexible 12-segment revolver heads combined with automatic nozzle chang-

ers 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 place-

ment 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 moving

PCBs) since the PCB does not move.

– Sophisticated optical centering systems (vision systems) for components and PCBs also en-

sure 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.

1.5.2 Head Modularity concept (HM)

The abbreviation HM in the designation of the SIPLACE S-23 HM placement system stands for

Head Modularity. 1

The aim of this concept is to allow any combination of 6-nozzle and 12-nozzle revolver heads to

be used on the placement system. A simple head change procedure will enable the system to

be quickly adapted to the requirements of individual placement jobs. 1

The head modularity concept will be implemented in the next development stage. Placement sys-

tems supplied with the designation HM are designed to be compatible with the new concept. 1
