Backlit Conveyor Aids Inspection Processes

Shana Leonard

A conveyor includes a light source suited for inspection processes.

Equipped with an internal light source, a conveyor illuminates parts during visual and automated inspection processes. The AccuVision conveyor, manufactured by Conveyor Technologies Ltd. (Milford, OH), houses a variety of features that serve to enhance defect detection in a range of industries, including the medical manufacturing industry.

Incorporated in the AccuVision internal backlit conveyor is an internal light source rated for 16,000 hours, which features a color-rendering index of 82+ and is available in warm white, cool white, and daylight tones. Strategically placed isolation mounts reduce vibration of the light source for maximum efficacy. The light field is offered in five lengths ranging from 7 to 32 in., while width is customizable through the use of multiple banks of lights.

Additional features of the conveyor expand inspection capabilities. High-frequency ballasts enable product compatibility with high-speed digital cameras. Aluminum-extruded sides with dual tee-slots built into a single- piece steel frame allow for the attachment of auxiliary devices. Belt widths range from 2.5 to 24 in., while the thickness of the conveyor remains fixed, measuring 2.28 in. Conveyor drives are offered in fixed speed, variable speed, and indexing versions with controllable acceleration, deceleration, and index, or secondary speed, selection.

Although the AccuVision conveyor integrates several unique features,it also retains some characteristics of the company’s standard conveyors. Among these standard features is the company’s touted two-minute belt change, which is possible when the conveyor is mounted on the company’s open-stand design.

“AccuVision’s strong uniform light field and controlled movement can assist in achieving defect-free products by facilitating more accurate and greater rates of visual inspections with sensors, cameras, and even the human eye,” says Charles Mitchell, president of Conveyor Technologies.
