YANRUN YR-W Horizontal Image Measuring System

Overview

The YANRUN YR-W Horizontal Image Measuring System is an opto-mechanical coordinate measuring instrument engineered for high-precision geometric metrology of medium-to-large workpieces with complex profiles, asymmetrical features, or extended axial dimensions. Unlike vertical CMM-based vision systems, its horizontal configuration enables stable, gravity-aligned measurement of cylindrical, tubular, or elongated components — such as shafts, connectors, hydraulic fittings, and precision-machined housings — without requiring repositioning or fixturing-induced deformation. The system operates on the principle of non-contact optical magnification and digital edge detection: a high-resolution industrial camera captures real-time video through interchangeable telecentric objectives and a continuously variable zoom lens; sub-pixel interpolation algorithms then compute feature centroids, distances, angles, radii, and form deviations against calibrated reference coordinates. Designed for ISO 17025-aligned quality laboratories and production-floor metrology stations, the YR-W delivers traceable dimensional verification in accordance with ISO 10360-7 (CMM performance verification) and supports compliance workflows required under IATF 16949 and AS9100.

Key Features

• Horizontal gantry architecture optimized for axial symmetry and long-part measurement, minimizing gravitational sag effects during Z-axis focusing.
• Three-axis motorized motion control (X: 300 mm, Y: 125 mm, Z: 150 mm focus travel) with 1 µm digital encoder resolution and bidirectional repeatability < ±2 µm.
• Multi-objective optical path: standard 1× telecentric tube with optional 0.5× (wide-field) and 2× (high-magnification) configurations, enabling flexible field-of-view selection from 40 mm down to 0.8 mm.
• 0.7–4.5× continuous zoom lens with calibrated magnification scaling, supporting video magnifications from 15× to 380× and corresponding object-side fields ranging from 20 mm × 3.2 mm to 5 mm × 0.8 mm.
• ±15° rotational tilt stage (about Y-axis) for angular inspection of bevels, chamfers, and multi-faceted geometries without manual part rotation.
• Integrated 19″ industrial-grade LCD display with anti-glare coating and embedded measurement UI; all positional data synchronized to encoder feedback in real time.
• Rigid cast-iron base and granite bridge structure ensuring thermal stability and vibration damping; total mass of 200 kg enhances dynamic rigidity during rapid axis traversal.

Sample Compatibility & Compliance

The YR-W accommodates parts up to 300 mm in length along the X-axis and 125 mm in width (Y), with maximum height clearance of 150 mm under the objective. Its horizontal orientation permits direct loading of shafts, flanges, injection-molded housings, and stamped metal brackets — particularly those exceeding the vertical clearance or weight limits of upright systems. All optical components comply with ISO 10110-3 (surface imperfections) and ISO 9022-3 (environmental resistance). Mechanical performance adheres to ISO 10360-7 Annex B for image-based coordinate measuring systems. The instrument supports GLP/GMP documentation requirements via timestamped measurement logs, user-access-level permissions, and audit-trail-capable software export (CSV, DXF, PDF report templates).

Software & Data Management

The system ships with YANRUN VisionMetro Pro — a Windows-based metrology suite supporting ISO/IEC 17025-compliant reporting. Core functions include automatic edge detection (sub-pixel Sobel/Canny hybrid), geometric construction (best-fit lines, circles, cones), GD&T evaluation (concentricity, parallelism, profile of a line/surface), and statistical process control (SPC) charting. Measurement data is stored in encrypted SQLite databases with full revision history; export formats include ANSI/ASME Y14.5-compliant GD&T annotations, STEP AP214 geometry files, and FDA 21 CFR Part 11–ready PDF reports featuring electronic signatures and tamper-evident hashes. Software updates are delivered via secure HTTPS channel with SHA-256 integrity verification.

Applications

• Automotive: Valve stems, brake caliper pins, transmission synchronizer rings, and turbocharger housings requiring coaxiality and runout verification.
• Aerospace: Hydraulic manifold blocks, fuel nozzle bodies, and actuator linkages where angular tolerances ≤ ±0.1° must be validated across multiple datum planes.
• Medical device manufacturing: Stainless-steel surgical instrument shafts, dental implant abutments, and catheter hubs demanding surface finish-independent profile measurement.
• Electronics: Precision-machined heat sink fins, connector housings, and RF shielding enclosures with tight positional tolerances on coplanar features.
• Tool & die: Inspection of EDM-machined electrode contours, progressive die inserts, and mold cavity surfaces prior to polishing cycles.

FAQ

What is the maximum part weight the YR-W can accommodate on its stage?
The instrument’s structural design supports parts weighing up to 15 kg directly on the stage; however, the recommended external platform (≥350 kg capacity) ensures vibration isolation and long-term mechanical stability.
Does the system support automated measurement routines for batch inspection?
Yes — VisionMetro Pro includes scriptable measurement sequences (VBScript-based), programmable fixture alignment, and pass/fail logic with configurable tolerance bands per feature.
Is calibration certification included with delivery?
Each unit ships with a factory calibration certificate traceable to NIM (National Institute of Metrology, China), including encoder linearity verification, optical magnification calibration, and coordinate accuracy validation per ISO 10360-7.
Can the YR-W integrate with existing MES or QMS platforms?
Native RESTful API and OPC UA server modules enable bidirectional data exchange with SAP QM, Siemens Opcenter Quality, and PTC Windchill QMS for real-time SPC dashboarding and nonconformance workflow initiation.
What environmental conditions are required for optimal operation?
Ambient temperature: 20 ± 1 °C; humidity: 40–60% RH non-condensing; vibration class: ISO 230-2 Class 2; requires stable power with ≤5% voltage fluctuation and EMI filtering per IEC 61000-4-5.
