Overview

The Openex Hexagon Nuts Inspection Machine is an intelligent, high-speed visual inspection solution developed for the complete quality assurance of hex nuts. It replaces manual sampling with fully automated inspection to ensure every piece meets your dimensional and surface quality standards.

Equipped with precision optics, high-resolution cameras, and AI-powered analysis software, the system captures images from multiple angles to evaluate both size and surface integrity.

Advantages

• Achieve 100% inspection coverage instead of manual sampling
• Reduce labor cost and human error
• Improve production efficiency and defect traceability
• Guarantee customer satisfaction with consistent quality
• Compatible with Industry 4.0 systems for smart factory integration

Specifications

• Inspection Objects: Hexagon Nuts (including flange nuts, thin nuts, and custom variants)
• Inspection speed: up to 300 pcs per minute
• Dimensional Measurements: Across flats (AF), Across corners (AC), Thread hole diameter, Flange outer diameter, Total height
• Surface & Defect Detection: Burrs on edges or threads, Press marks or dents on hex faces, Scratches or dents on flange bottom surface, Missing or incomplete thread segments on bottom face.
• Inspection Accuracy: ±0.01 mm (depending on part size and camera setup)
• Lighting: Coaxial, backlight, and side illumination for optimal detection

Working Principle

Hex nuts are automatically aligned and fed through a vibrating bowl feeder and transferred onto a rotating glass disk. Multiple industrial cameras capture images of each nut’s top, bottom, and side surfaces.

The AI software analyzes each image in real time to:

• Measure dimensions precisely
• Identify and classify surface defects
• Automatically sort OK/NG products via pneumatic ejectors

Features

• High-Speed Performance - Inspection speed up to 300 pcs per minute, ideal for mass production environments.
• Versatile Compatibility - Compatible with multiple hex nut types and sizes through quick-change setups.
• AI-Powered Vision - Deep learning algorithms ensure accurate defect detection even for complex or subtle defects.
• Reliable & Stable Operation - Continuous 24/7 operation with minimal maintenance.
• User-Friendly Interface - Intuitive software interface, easy setup and calibration, minimal operator training required.
