Zhengye Capacitor X-ray Inspection System (Model: ZXI-3000 Series)

Overview

The Zhengye ZXI-3000 Series Capacitor X-ray Inspection System is an industrial-grade, fully automated inline X-ray detection platform engineered for non-destructive evaluation (NDE) of electrolytic and film capacitors during high-volume manufacturing. Leveraging dual-source microfocus X-ray transmission imaging (10–160 kV adjustable), the system generates high-contrast radiographic projections to resolve internal structural anomalies—including anode/cathode misalignment, foil wrinkling, dielectric voids, solder joint integrity, and winding layer delamination—with sub-5 µm effective spatial resolution under optimized geometry. Designed specifically for capacitor production lines, it integrates seamlessly into conveyor-coupled environments and supports real-time pass/fail classification at up to 60 parts per minute—enabling 100% in-process inspection without throughput compromise.

Key Features

• Automated Defect Recognition Engine: Proprietary vision algorithm suite performs real-time pixel-level analysis against user-defined defect templates (e.g., gap width > 30 µm, concentricity deviation > 0.15 mm), delivering binary classification output with configurable confidence thresholds.
• 2.5D Metrological Mode: Supports calibrated geometric measurements—including linear distance, circle diameter, concentricity between nested electrodes, and radial offset from centroid—traceable to NIST-traceable step gauges; measurement uncertainty < ±1.2 µm (k=2) at 10× magnification.
• CNC Path Programming: Enables repeatable multi-angle acquisition sequences (up to 99 waypoints) with motorized tilt/rotation stage; path data stored in encrypted .cnc files with timestamped version control for audit readiness.
• Click-to-Go Navigation: 1920×1080-pixel live navigation map overlays real-time X-ray preview; mouse selection triggers servo-driven stage repositioning within ≤1.8 seconds (±5 µm repeatability).
• Multi-Format Image Pipeline: Captures raw projection frames at 12-bit depth; applies real-time contrast enhancement (CLAHE), noise suppression (non-local means), and edge sharpening prior to storage or export.

Sample Compatibility & Compliance

The ZXI-3000 accommodates cylindrical, radial, and SMD-style capacitors ranging from 3 mm to 50 mm in height and 2 mm to 35 mm in diameter. Fixturing options include vacuum-based universal chucks and custom-machined nest trays compliant with IPC-A-610 Class 3 mechanical retention standards. All radiation shielding meets IEC 61000-6-4 (EMC) and GBZ 137-2019 (China X-ray Equipment Safety Requirements); leakage dose < 0.5 µSv/h at 5 cm from cabinet surface. System validation documentation supports IQ/OQ/PQ protocols aligned with ISO 13485 and FDA 21 CFR Part 11 requirements for electronic component traceability.

Software & Data Management

Zhengye VisionSuite™ v4.2 operates on Windows 10 IoT Enterprise LTSB with role-based access control (Admin, Operator, QA Auditor). Each inspection event logs metadata—including X-ray parameters, stage coordinates, measurement results, annotated images, and operator ID—into a SQLite database with SHA-256 hashed integrity verification. Export modules generate CSV files for SPC integration (Minitab, JMP), DICOM-compliant archives for enterprise PACS, and PDF reports embedding measurement callouts and statistical summaries (Cp/Cpk, PPM defect rate). Audit trail records all configuration changes, result overrides, and user logins with immutable timestamps.

Applications

• Electrolytic capacitor quality gate: detecting foil fold defects, seal ring cracks, and electrolyte fill level inconsistencies.
• Film capacitor process validation: verifying winding tension uniformity, electrode edge alignment, and metallization continuity.
• Supercapacitor R&D: analyzing porous electrode architecture, separator placement accuracy, and weld seam integrity in asymmetric designs.
• Failure analysis lab support: correlating field-return failures with internal morphology via comparative radiography (golden unit vs. failed unit).
• Supplier qualification audits: generating standardized inspection reports for Tier-1 automotive electronics (AEC-Q200 compliant components).

FAQ

Does the system support automated report generation for ISO/TS 16949 compliance?
Yes—VisionSuite™ exports structured XML reports containing full metrology traceability, equipment calibration status, and operator authentication, satisfying clause 8.6.2 of IATF 16949.
Can the software interface with MES or SCADA systems?
It provides OPC UA server functionality and RESTful API endpoints for bidirectional data exchange (e.g., part ID pull, pass/fail push) compatible with Siemens SIMATIC, Rockwell FactoryTalk, and custom MES platforms.
What is the typical lead time for custom fixturing design?
Standard fixtures ship with system delivery; custom nest development requires 12–15 business days after CAD drawing approval and mechanical tolerance confirmation.
Is remote diagnostics supported?
Yes—secure TLS-encrypted remote desktop access (TeamViewer QT module) enables Zhengye Field Application Engineers to perform firmware updates, parameter optimization, and algorithm tuning without onsite visits.
How often does the X-ray tube require replacement?
Microfocus tubes are rated for ≥8,000 operating hours; predictive maintenance alerts trigger at 7,200 hours based on cumulative kV·mA·s logging, with full replacement kits available under extended service contracts.
