Reading rotating lithium-ion batteries during transport

On production lines for cylindrical workpieces such as lithium-ion batteries, individual item management and ensuring traceability during high-speed transport are essential. However, there has been a challenge in stably reading barcodes and 2D codes printed on the sides of workpieces rotating on a conveyor, as the printed surface is not always facing up. Reading errors directly lead to decreased productivity and quality control risks.

A reading system utilizing the KEYENCE AI-powered code reader, SR-X Series, solves this problem. The SR-X Series combines an overwhelmingly wide field of view with long-range performance, reliably capturing codes on batteries flowing in multiple rows on a conveyor, even if the printed surface orientation changes by a few degrees due to rotation. Its unique, advanced image processing algorithm instantly decodes even challenging codes printed on curved surfaces or with low print contrast. It achieves stable reading without stopping high-speed production lines, building reliable traceability. This improves the quality control level in FA environments, contributing to the prevention of defective product outflow and the maximization of productivity.
