In industrial production, manufacturers often need to encode production information such as time and location, solder temperature, component batch number, and test data to form a QR code printed on the material;

In the electronics industry, the QR codes on PCB circuit boards are often very small, but due to quality inspection, traceability, and other requirements during the production process, it is necessary to quickly and accurately read these codes within a larger field of view.

There are many scenarios with similar requirements, and in this issue, Xiao Ming will share the application of Meiji intelligent code reader in the large field tray code reading scenario~

Testing requirements

Mobile reading of DM code on tray

Selection analysis:

1. On the tray, there are 10 barcodes in a row for a total of 21 rows, which need to be read all at once

2. Reading a total of 210 barcodes from the tray requires high stability from the barcode reader

3. A barcode with a size of only 2.5X2.5mm requires a high pixel barcode reader

4. The barcode is relatively small and needs to be installed closer when reading, resulting in a relatively smaller field of view

solution

Intelligent Code Reader RCD-AI500

1. Due to the small size and high information density of the target being tested, high-precision code reading devices are required for accurate and rapid recognition. The Meiji RCD-AI500 series large depth of field barcode reader has a large depth of field range during barcode reading, which enables clear imaging and accurate recognition of barcodes within a certain distance range. It can ensure reliable reading of barcode information at different distances and angles, avoiding reading errors or inability to read due to barcode size being too small.

2. 5 million pixels, high resolution, more suitable for reading small-sized QR codes

3. When the reading height is 150mm, the field of view is 130 * 100, which meets the requirement of reading 10 codes in one row

4. The algorithm is more intelligent, with faster response speed, and can meet the needs of mobile reading

5. Multiple light sources to choose from, as well as polarization and non polarization options, can easily handle reflective scenes

6. The software is easy to operate and the Chinese interface is user-friendly
