Abstract
Quality assurance is one of the most critical stages in modern manufacturing, directly affecting product reliability and safety. Traditional visual inspection relies heavily on human inspectors, which is labor-intensive, subjective, and difficult to scale in high-throughput production lines. Recent advances in deep learning and multi-agent systems offer new possibilities for automating and enhancing visual inspection accuracy. This study proposes a Multi-Agent Deep Learning Visual Inspection System (MADL-VIS) for industrial manufacturing quality control. The system employs a two-stage detection pipeline: a deep learning-based defect detection module that identifies surface defects from visual inputs, and a multi-agent collaboration module that performs defect classification, root cause analysis, and inspection report generation. Specifically, the detection module leverages a convolutional neural network architecture with attention mechanisms to extract fine-grained defect features from product surface images. The multi-agent module decomposes the post-detection workflow into specialized tasks—defect categorization, severity scoring, cause inference, and documentation—each handled by a dedicated LLM-powered agent. Experiments conducted on three publicly available industrial inspection datasets demonstrate that the proposed system achieves an average defect detection accuracy of 91.3% and a classification accuracy of 88.7%. The multi-agent post-processing module reduces the average inspection cycle time by 38% compared with manual analysis, while the root cause inference agent achieves a consistency rate of 79% with domain expert assessments. This study validates the effectiveness of integrating deep learning-based visual detection with multi-agent collaborative analysis for automated industrial quality assurance.
