Vision

Published on 6-Jan-2009

The MG-8R works with several types of vision tools. The standard MG-8R is equipped with a fiducial camera for fiducial recognition and bad mark sensing. This camera can also be used as a highly accurate teaching device for PCB data (if CAD data is not available), automatic calibration and inspection purposes. For component alignment, a standard line array camera is also available. In addition to these standard cameras, some optional cameras can be configured:

Side view camera

A side view camera system is available for use in combination with the line array camera. It is especially useful for small components and has no effect on recognition time. It offers quality enhancement by:

• improving pick and mounting reliability (bring back check)
• detecting component presence and orientation at the nozzle in Z direction.

Second line array camera

A second line array camera reduces head beam travel thus shortening the mounting cycle time on boards with a high unique component count. It:

• improves output for components picked from rear feeders
• mounts in rear between two 24-position feeder bars.

Single area CCD camera

The MG-8R can be equipped with a single area CCD camera for extending the component range (with 55 mm square components). It improves mounting accuracy by using fine mode/multi recognition.

3D vision system

In combination with the line array camera, an on-the-fly 3D vision system checks the
co-planarity of any leaded component or the individual ball height for BGA components with minimal speed penalty. It:

• measures the co-planarity of QFPs and BGAs
• provides a cost-effective 3D vision system solution
• checks co-planarity on-the-fly.
