Yuelian YL-VMS 2D Vision Measuring System

Overview

The Yuelian YL-VMS 2D Vision Measuring System is a precision optical coordinate measuring instrument engineered for non-contact geometric metrology of planar components in quality control, R&D, and production environments. It operates on the principle of digital image acquisition and sub-pixel edge detection: a high-resolution Sony color CCD camera captures magnified images of the workpiece under controlled LED illumination; geometric features—such as points, lines, circles, arcs, and polygons—are extracted via real-time image processing algorithms and spatially referenced to a calibrated Cartesian coordinate system defined by linear optical encoders on all three axes (X, Y, Z). Unlike tactile CMMs, this system eliminates mechanical probing forces and thermal drift risks, making it especially suitable for thin, soft, or delicate parts—including stamped metal sheets, PCBs, gaskets, plastic injection-molded components, and precision machined fixtures. Its granite base ensures long-term structural stability and thermal inertia, while the NAVITAR dual-focus zoom objective provides consistent optical magnification across its 0.7×–4.5× range without parallax shift—critical for measurement repeatability per ISO 10360-7 and VDI/VDE 2617 Part 8 standards.

Key Features

• Granite base construction with natural aging treatment, delivering exceptional rigidity and long-term dimensional stability under ambient workshop conditions.
• Precision linear optical encoders integrated on X-, Y-, and Z-axes, enabling position resolution down to 1 µm and supporting traceable calibration against certified gauge blocks.
• Dual-mode LED cold-light illumination system: coaxial surface light for diffuse reflection analysis and oblique contour light for high-contrast silhouette edge detection—minimizing thermal influence on temperature-sensitive samples.
• NAVITAR telecentric-corrected zoom lens with fixed magnification ratios and calibrated pixel-to-unit scaling, ensuring measurement linearity across the entire field of view.
• MCINS Manual Edition software platform: a Windows-based metrology suite supporting point, line, circle, arc, angle, distance, parallelism, perpendicularity, concentricity, and multi-coordinate system alignment (e.g., best-fit, iterative, or datum-based).

Sample Compatibility & Compliance

The YL-VMS accommodates flat or low-relief parts up to 300 mm × 200 mm in footprint and 150 mm in Z-height (subject to model configuration). It supports reflective, translucent, and opaque materials—including anodized aluminum, stainless steel, FR4 PCB substrates, silicone elastomers, and acrylic lenses—without requiring surface preparation. All measurements comply with fundamental principles outlined in ISO 14253-1 (Geometrical Product Specifications) and ASTM E29 (Standard Practice for Using Significant Digits in Test Data). While the system itself does not carry CE or UKCA marking (as it is distributed under OEM/distributor framework), its mechanical design, encoder resolution, and software traceability pathways align with GLP documentation requirements for internal QC labs. Calibration certificates can be issued per ISO/IEC 17025-accredited third-party providers upon request.

Software & Data Management

MCINS Manual Edition provides intuitive, workflow-driven measurement sequencing with full audit trail logging: every operator action, parameter change, and result export is timestamped and user-tagged. Measurement reports are exportable in native formats including CSV (for statistical process control integration), XLSX (for SPC charting in Excel), DOCX (for QA documentation), and DXF (for direct import into CAD platforms such as AutoCAD, SolidWorks, or Fusion 360). The software supports multi-language UI (English, Simplified Chinese, Spanish), customizable report templates, and configurable tolerance zones with pass/fail color coding. Although MCINS does not natively support FDA 21 CFR Part 11 electronic signature or audit trail encryption, it allows integration with external document management systems (DMS) via standardized file I/O protocols—enabling compliance-ready deployment in regulated manufacturing settings when paired with validated IT infrastructure.

Applications

This system is routinely deployed in Tier-1 automotive suppliers for verifying gasket hole patterns and bracket slot dimensions; in electronics contract manufacturers for inspecting solder mask openings and fiducial placement accuracy on PCB panels; in medical device component suppliers for validating tolerances on microfluidic channel widths and catheter hub geometry; and in academic metrology labs for teaching coordinate measurement fundamentals and image-based dimensional analysis. Its manual operation mode offers pedagogical transparency and cost-effective entry into vision-based metrology—ideal for laboratories prioritizing hands-on operator training, small-batch verification, or legacy CAD comparison workflows.

FAQ

Is the YL-VMS compatible with automated stage movement or CNC programming?
No—the YL-VMS is a manually operated system. It does not include motorized axes or G-code interpreter functionality. For automated inspection, consider Yuelian’s CNC-enabled VMS series (e.g., YL-VMS-CNC) or third-party motion controller integration.
Does the MCINS software support GD&T evaluation (e.g., true position, profile of a surface)?
Basic GD&T functions—including positional tolerance calculation relative to datums—are available in MCINS Manual Edition. Advanced GD&T (e.g., composite controls, runout, or profile of a line with material condition modifiers) requires the optional MCINS Pro add-on module.
Can measurement data be linked to a company’s ERP or MES system?
Direct API-level integration is not supported. However, exported CSV/XLSX files can be ingested via standard middleware (e.g., Python scripts, Power Automate, or OPC UA gateways) into most ERP/MES platforms for downstream SPC or nonconformance tracking.
What calibration services are recommended for maintaining traceability?
Annual recalibration using NIST-traceable step gauges and ring gauges is recommended. Yuelian-certified service partners in North America and Europe provide on-site calibration with ISO/IEC 17025-compliant certificates.
Is technical support available in English for international users?
Yes—Yuelian’s global distributor network provides English-language remote support, software updates, and application engineering consultation for installation, validation, and troubleshooting.
