Reading codes on battery packs through film

In the manufacturing process of battery packs used in smartphones and electronic devices, reading codes through protective or shrink-wrap films is a crucial process for ensuring traceability. However, the gloss and reflection on the film surface often prevent stable reading of 2D codes like QR codes and DataMatrix, leading to production line stoppages and quality control issues.

The KEYENCE AI-powered code reader, SR-X Series, offers an effective solution to this challenge. The SR-X Series can be equipped with powerful built-in lighting and an optional polarizing filter attachment to suppress reflections. This enables stable reading even on glossy films or curved surfaces, which were previously difficult to read. Furthermore, the 'auto-tuning function' automatically sets the optimal imaging conditions with the press of a button, allowing anyone to easily build a high-precision reading environment. Since a single Ethernet cable can handle both communication and power supply, it is easy to retrofit into existing equipment with space and wiring savings. This enhances process control for battery packs and other electronic components, contributing to improved quality and productivity.
