Overview
The DingHong GU-SMF Series One-Touch Flash Measurement System is a vision-based, non-contact geometric metrology instrument engineered for high-throughput, high-reproducibility dimensional inspection in precision manufacturing environments. It operates on the principle of telecentric imaging combined with sub-pixel edge detection and real-time image stitching—enabling full-field measurement across a 315 × 190 mm field of view without mechanical scanning or part repositioning. Unlike traditional coordinate measuring machines (CMMs) or manual optical comparators, the GU-SMF eliminates reliance on fixturing, manual alignment, or operator-dependent programming. Its dual telecentric optical architecture ensures minimal perspective distortion, uniform magnification across depth, and stable edge contrast—critical for traceable length measurements compliant with ISO 10360-7 and VDI/VDE 2634 Part 2 standards. Designed for integration into automated production lines and quality control labs, the system supports both standalone operation and factory-floor deployment under ISO 9001 and IATF 16949 quality management frameworks.
Key Features
- Dual telecentric lens assembly with motorized axial illumination adjustment—eliminates object-side and image-side perspective errors and maintains consistent edge fidelity across varying part heights (up to ±15 mm working distance tolerance).
- High-stability linear motor motion platform equipped with 0.1 µm resolution closed-loop optical encoders on all axes—ensures repeatable positioning accuracy, zero backlash, and no cumulative error during image stitching or multi-region measurement.
- Quad-channel multi-angle + low-angle directional lighting system—enhances surface texture discrimination and contour contrast for challenging materials including matte plastics, anodized aluminum, and elastomeric surfaces.
- Motorized elevation-adjustable ring light—dynamically optimizes illumination angle and intensity per measurement task to maximize edge sharpness and reduce specular interference.
- Real-time parallel processing architecture—executes up to 1,600 discrete geometric feature measurements (points, lines, circles, arcs, profiles) within ≤7 seconds per field-of-view acquisition.
- Zero-contact measurement modality—preserves surface integrity of delicate components such as MEMS devices, thin-walled injection-molded parts, and precision stamped connectors.
Sample Compatibility & Compliance
The GU-SMF Series accommodates a broad spectrum of industrial parts—including machined metal components, plastic housings, PCB assemblies, gaskets, O-rings, threaded fasteners, gear blanks, and spring forms—without requiring custom tooling or physical contact. Parts may be placed freely within the measurement area; the system automatically detects orientation via template matching and aligns measurement routines to imported CAD geometry (DXF, STEP, IGES). All measurements adhere to ISO/IEC 17025 technical requirements for calibration laboratories and support GLP/GMP documentation workflows, including user access control, electronic signatures, and audit-trail logging per FDA 21 CFR Part 11. Optional SPC modules generate X̄–R charts, capability indices (Cp/Cpk), and trend analysis reports aligned with AIAG SPC Manual guidelines.
Software & Data Management
The proprietary GU-Metrology software features an intuitive graphical interface optimized for rapid operator training and minimal supervision. Core capabilities include CAD-driven offline programming, auto-focus optimization, multi-frame image stitching, sub-pixel contour extraction, and GD&T-compliant reporting (per ASME Y14.5–2018 and ISO 1101). The software natively supports point cloud registration, profile comparison against nominal geometry, and automated pass/fail evaluation with configurable tolerance zones. Measurement data exports to CSV, PDF, XML, and SQL-compatible formats; historical records are stored with timestamp, operator ID, machine configuration, and environmental metadata. Integration with MES/ERP systems is supported via RESTful API and OPC UA protocols, enabling traceability from raw material receipt through final inspection.
Applications
This system is deployed extensively in Tier-1 automotive suppliers for rapid verification of brake caliper brackets, fuel rail components, and sensor housings; in consumer electronics for inline inspection of camera module frames and flex circuit carriers; in medical device manufacturing for dimensional validation of catheter hubs and syringe barrels; and in precision machining shops for first-article inspection of aerospace turbine blade fixtures. Its ability to perform simultaneous measurement of positional tolerances, form deviations (flatness, circularity), and thread parameters (pitch diameter, lead angle, flank angle) makes it especially suitable for multi-feature parts where conventional CMM throughput would bottleneck production flow.
FAQ
Does the GU-SMF require part-specific fixtures or manual alignment?
No. Parts are placed freely within the 315 × 190 mm field; the system performs automatic orientation recognition and template-matching against CAD references.
Can measurement programs be created offline without physical parts?
Yes. CAD files (DXF/STEP/IGES) are imported directly into the software to generate fully functional inspection routines prior to part arrival.
Is the system compliant with regulatory documentation standards for audited environments?
Yes. Software includes 21 CFR Part 11-compliant audit trails, role-based access control, and electronic signature support for GxP-regulated operations.
What types of geometric features can be measured simultaneously?
Points, lines, circles, arcs, conics, splines, curves, R-corners, C-angles, gear tooth profiles, thread forms, rubber seal cross-sections, and custom-defined composite features.
How is measurement uncertainty managed across varying part heights?
The dual telecentric optics and motorized illumination elevation ensure consistent depth-of-field and edge contrast across ±15 mm Z-height variation—validated per ISO 15530-3 using calibrated step gauges.
