Better than 0.5 s Single-Piece Detection Cycle (Including AI Inference)
6 Types of Welding Defects Automatically Classified
Product Introduction
JY-NIRS is the company's second-generation model launched on the basis of JY-T980, designed as an online intelligent inspection device for plastic laser welding processes. The device is based on near-infrared transmission imaging, acquiring the full-screen light transmittance distribution of workpieces through high-uniformity planar illumination and telecentric imaging. A local AI model performs defect segmentation and classification, automatically providing OK/NG judgments and outputting a defect list. The detection capability extends from "measuring transmittance values" to "identifying and locating welding defects": the minimum recognizable defect has been improved from 0.3 mm to 0.05 mm, and the judgment logic has been upgraded from manual thresholds to AI self-learning determination.
Core Advantages
Micro-Defect Visibility: Minimum recognizable defect ≤ 0.05 mm, approximately 6 times improvement compared to JY-T980.
AI Judgment Replacing Manual Thresholding: Capable of identifying combined defects of overall qualification and local false welding.
Automatic Defect Classification: Six types including false welding, material shortage, porosity, burn marks, foreign substances, and cracks.
Data Closed-Loop: Standard MES interface and SPC statistical analysis; full traceability with one item, one code.
