KQ-TM1 Universal Barcode Detector – High-Speed 1D Code Anti-Mixing Inspection

The working principle of KQ-TM1 universal barcode detector adopts high-frequency linear image scanning. The built-in high-speed optical sensor captures barcode graphics at 1000 scans per second, then the control chip decodes UPC, EAN, Code 128, Industrial 2/5 and all mainstream 1D barcode formats, comparing scanned data with pre-set standard codes in real time.

The adjustable scanning distance ranges from 65mm to 500mm, adapting to cartons of different thicknesses and conveyor heights, with a minimum identifiable barcode unit of 0.125mm to recognize tiny mini barcodes on small cosmetic and drug boxes.

Key advantages include ultra-compact size for flexible multi-position mounting, zero-delay signal output and powerful anti-mixing logic. Unlike slow offline barcode checking, KQ-TM1 runs synchronously with folder gluer speed, intercepting mixed batch cartons the moment abnormal barcodes pass through. It records the latest 10 groups of defective barcode data for factory audit traceability, supporting alarm prompt or automatic NG ejection linkage according to production demands. The dustproof sealed casing suits harsh printing workshop environments with ink and paper dust, ensuring long-term stable continuous operation without frequent maintenance.

This detector is widely deployed in pharmaceutical packaging, food cartons, daily chemical boxes and e-commerce outer packaging to solve cross-batch mixing issues that trigger market complaints and product recalls. Small printing workshops and large mass-production manufacturers both benefit from its low investment threshold and simple wiring installation. The system eliminates tedious manual barcode sorting posts, streamlining post-press workflows and standardizing packaging batch management. It can work independently or connect with glue detection and vision systems to build a full set of multi-functional inline quality control lines.
