Barcode Reading Solution for Mobile Phone Back Covers

Industry Demand

The system must read 3×3mm Data Matrix (DM) codes with a 99% success rate. It supports dynamic code reading for production lines with speeds exceeding 500mm/s. Decoded data can be exported in Excel format. Failed decodings trigger audible and visual alarms.

Customer pain points:

Currently, customers are using manual handheld scanning guns for scanning, which results in low efficiency and the risk of double scanning or missed scanning. The barcodes are QR codes printed on labels, which are manually pasted and may become blurred due to friction, making it impossible for the handheld scanning guns to read them.

Project difficulties:

The project is applied to QR code reading on the back cover of mobile phones, and it needs to meet the requirements of dynamic reading and an accuracy rate of over 99%. Due to the thin thickness of the product, the normal installation of the photoelectric sensor on the side of the device cannot provide stable sensing.

Selection:

The R-3350 product from the R-3000 series of intelligent barcode readers is adopted. The product integrates a megapixel sensor and a high-performance processing chip, boasting super computing power and capable of stably reading barcodes moving at high speed. A distance sensor is installed above the device to sense downward, triggering the barcode reader to take a photo when the product flows into the sensing area.

Advantage:

The R-3350 reader of the EVOC Jinma intelligent reader R-3000 series adopts the latest generation of AI algorithms. Its rich database not only meets customers' accuracy requirements but also features a self-learning function, significantly reducing the cost of customer debugging;

The compact body of the R-3350 barcode reader, coupled with barcode reader holders that can be adjusted to different angles, greatly enhances the flexibility of the reader, allowing it to excel in various complex scenarios. Additionally, with different colored light sources and optional polarizers, it can easily handle different materials or materials that are prone to reflection. The adjustable focal length of the R-3350 not only meets the needs of customers for different models of applications but also saves customers time during model changes and debugging.
