Vision sensor accommodates four cameras

JULY 9--Omron Electronics LLC (Schaumburg, IL; www.info.omron.com) has developed a four-camera machine-vision sensor for use in multi-angle inspection applications. Its real-time rotation position compensation capability searches for parts or features located at random angles and positions while maintaining inspection speeds of up to 6000 parts/min. An edge code technology can accomplish precise positioning under poor imaging conditions. Defect inspection capability finds fine scratches, dirt, and deformities. Quest OCR and OCV algorithms uses built-in character libraries to discern multiple printed alphanumeric characters simultaneously regardless of shape or size. The F250 needs no prior character learning.

A built-in Ethernet port permits network communications. A fine matching algorithm quickly and accurately detects differences between the registered model and the image under measurement to reveal fine defects on printed labels and graphic patterns. Expandable memory uses 128-Mbyte flash-RAM cards for setup programs and image storage and for data transfers to other F250s or PCs.

The F250 cameras can be fitted with a variety of Omron and CCs America light sources, which enables users to set and save light intensity and direction during inspection setup routines. They are well suited for high-speed measurement and inspection applications, including product or package sorting, pharmaceutical package and lot code/date code inspection, high speed bottle inspection, electronics inspection, random position reference and high speed robotic tool guidance.
