YANRUN YR3020CNC Fully Automated 2D/3D Vision Measuring Machine

Overview

The YANRUN YR3020CNC is a fully automated, high-stability vision measuring machine engineered for precision geometric metrology in industrial quality control and R&D environments. Built on a moving-bridge architecture with a Grade 00 granite frame—characterized by thermal stability, vibration damping, and sub-micron flatness—the system delivers repeatable dimensional measurement across X, Y, and Z axes. Its core measurement principle relies on digital image acquisition via a calibrated optical path, combined with closed-loop servo motion control and real-time edge detection algorithms. The machine conforms to foundational metrological principles defined in ISO 10360 (Geometrical Product Specifications — Acceptance and Reverification Tests for Coordinate Measuring Machines) and supports traceable calibration practices aligned with ISO/IEC 17025 requirements. Designed for both 2D profile analysis and 3D surface-height mapping (when equipped with optional Renishaw tactile probe), it serves as a primary metrology platform for PCB assembly verification, LCD panel alignment inspection, sheet metal component validation, and aerospace structural part certification.

Key Features

• Moving-bridge granite structure with Grade 00 material (flatness ≤ 3 µm) ensures long-term mechanical stability and minimal thermal drift.
• Fully CNC-controlled triaxial motion system: XY-axis speed up to 280 mm/s; Z-axis speed up to 100 mm/s; acceleration optimized for smooth trajectory execution.
• Closed-loop optical grating scales with 1 µm resolution provide direct position feedback, eliminating backlash and pitch error accumulation.
• Hikvision GigE color industrial CCD camera enables high-fidelity image capture at frame rates compatible with dynamic autofocus and multi-region scanning.
• 6.5:1 motorized zoom lens maintains optical calibration across magnification range (0.7×–4.5×), eliminating need for recalibration during zoom transitions.
• Dual independent illumination subsystems: 5-ring 8-zone surface LED light (256-level programmable brightness per zone) and dedicated edge backlight (256-level control) enable adaptive contrast optimization for diverse material surfaces.
• Auto-focus algorithm computes optimal Z-position based on image sharpness gradient, supporting height-difference measurement with sub-pixel edge localization.
• Integrated temperature compensation module applies linear thermal expansion correction using user-input material coefficient and ambient temperature deviation from 20 °C reference.

Sample Compatibility & Compliance

The YR3020CNC accommodates parts up to 25 kg and 300 × 200 × 180 mm in volume, including rigid PCBs, stamped metal brackets, injection-molded housings, glass substrates, and machined aluminum components. Its non-contact optical measurement modality avoids part deformation or surface marking. The system supports compliance workflows required under ISO 9001, IATF 16949, and AS9100 quality management systems. When configured with Renishaw PH10M probe head and ruby stylus (optional), tactile probing extends capability to GD&T evaluation per ASME Y14.5 and ISO 1101 standards—including position, concentricity, parallelism, and perpendicularity. All measurement tasks can be logged with full audit trail (operator ID, timestamp, parameter set, raw image snapshot) to satisfy FDA 21 CFR Part 11 electronic record requirements when deployed in regulated manufacturing.

Software & Data Management

The CNC4000 intelligent metrology software suite provides a deterministic, scriptable measurement environment compliant with GLP/GMP documentation protocols. It features:

• Automated task sequencing with conditional branching (e.g., “if diameter tolerance exceeded → trigger re-measurement”)
• SPC-ready data export: .rst (native binary), .csv (for Minitab/JMP integration), .xlsx (customizable templates), .pdf (certified reports), .dxf/.dwg (CAD overlay comparison)
• Image-based GD&T evaluation: real-time rendering of tolerance zones, deviation heatmaps, and vector-based form error decomposition
• Multi-language UI (English, Simplified/Traditional Chinese, Japanese, Korean) with context-sensitive help and embedded metrology glossary
• Full CAD interoperability: import/export DXF/DWG; automatic alignment via feature matching; deviation color-mapping against nominal geometry
• Navigation engine with tiled panoramic stitching—enables macro-to-micro inspection without manual stage repositioning
• Secure user role management (Admin, Operator, QA Auditor) with password-protected configuration locks and encrypted log archives

Applications

This system is routinely deployed in:

• Electronics manufacturing: solder paste volume estimation, BGA ball coplanarity, fiducial mark registration accuracy, flex circuit trace width verification
• Display technology: LCD/OLED pixel array uniformity, bezel gap consistency, touch sensor electrode pattern fidelity
• Aerospace Tier-1 suppliers: turbine blade airfoil contour verification, composite layup alignment, fastener hole positional tolerance validation
• Medical device production: catheter tip concentricity, syringe barrel wall thickness variation, implant surface finish assessment
• Automotive stamping: flange angle deviation, hole-to-edge distance repeatability, weld seam geometry quantification

All applications benefit from the system’s ability to generate metrologically traceable, ISO-compliant inspection records suitable for first-article reports (FAI), PPAP submissions, and internal process capability studies (Cp/Cpk).

FAQ

Does the YR3020CNC support third-party calibration certificates?
Yes—calibration services are available through accredited labs (ISO/IEC 17025) with NIST-traceable artifacts; certificate includes uncertainty budget per ISO 15530-3.
Can measurement programs be exported and reused across multiple machines?
Yes—task files (.rst) contain full optical, motion, and algorithm parameters; compatible across YR3000-series platforms with identical hardware configuration.
Is SPC functionality built-in or requires external software?
Basic SPC charts (X-bar/R, Cp/Cpk, Pp/Ppk) are native; advanced multivariate analysis requires CSV export to statistical packages.
What is the recommended maintenance interval for optical calibration?
Lens calibration is performed automatically on startup; full system verification (using ceramic step gauge and ring gauge) is advised every 6 months or after 500 operational hours.
How does the system handle reflective or translucent samples?
Multi-zone surface lighting allows directional contrast tuning; polarization filters and diffused backlight modules (optional) mitigate specular reflection and subsurface scattering effects.
