6.1.1 Component vision module on the 12-segment Collect&Place head

The component vision module (see item 2 in Fig. 6.1 - 3) essentially consists of the following mod-

ules: 6

– Optical lens

– CCD chip for creating an electronic image of the component

– CCD camera amplifier

– Three illumination levels – flat, average and steep – for optimum illumination of a wide

range of component shapes

–“Illumination control” board for setting the intensity of the individual illumination levels.

The component camera system is fastened to the top of the Collect&Place head using four hexa-

gon socket-head screws. It is then held in place by two parallel pins. 6

The component camera system can be used to optically center and place components ranging

from 0402 up to and including PLCC 44 in size. The components therefore vary in size between

1.0mm x 0.5mm and 18.7mm x 18.7mm, and from 0.3mm and 6mm thick. The minimum lead

pitch can be as little as 0.5mm. 6
