Fully automatic spinneret mirror inspection instrument

The Fully Automatic Spinneret Mirror Inspection Instrument (Detector) is designed for automatic inspection of chemical fiber filament spinnerets, staple fiber spinnerets, and industrial yarn spinnerets of various shapes and specifications, including round, square, and rectangular dies. The instrument can also inspect spinning plates, spinneret mouthplates, and other specialized dies for hole shape, size, and blockage.

By analyzing the shape, size, and arrangement of spinneret holes, this instrument can detect any hole within the effective vertical and horizontal ranges, ensuring comprehensive and accurate inspection.

Manufacturing Standards

Produced according to GB/T19001-2016 / ISO9001 quality management system.

Mechanical and electrical design conforms to GB 5226.1-2008 standards.

Instrument Features

1. Mechanical System

Three-Axis Motion Control: Uses an automatic X-Y-Z three-axis platform (orthogonal robot) with imported AC servo positioning. Each axis features a precision ball screw drive, ensuring low noise, high precision, and repeat positioning accuracy up to ±0.01mm.

High-Resolution Lens: Equipped with a high-pixel lens with low distortion. No lens replacement is required when switching magnifications.

Industrial Camera: High-speed, high-resolution black-and-white industrial camera ensures distortion-free image capture for accurate measurement.

High-Strength Loading Fixture: Metal fixtures and table provide excellent load-bearing performance, easy replacement, and ensure flatness via precision grinding.

Display Interface: Built-in display allows real-time observation of the inspection process.

2. Electrical & Software System

Advanced Image Processing: Detects hole diameter, area, roundness, fouling rate, and other parameters automatically. Position of unqualified holes is recorded.

Custom Spinneret Templates: Users can input spinneret parameters for calibration.

Automatic Focusing: Lenses automatically adjust focus, improving inspection efficiency.

Data Management: Test results are stored in a database for easy recording and analysis.

Optimized Detection Path: Detection rate per hole: 0.2–1s, depending on spinneret specifications.

Flexible Operation: Different spinnerets can be tested by loading corresponding template files.

Industrial Control Computer: Equipped with X-Y-Z control, I/O card, adjustable light source controller, keyboard, and mouse for fast data transmission.

LED Illumination: Long-life LED light source ensures uniform lighting through spinneret holes for high-quality image capture.

All-in-One Design: High-strength metal construction with convenient spinneret fixture replacement.

Detection Method

Hole-by-Hole Scanning: Fully automatic scanning of all spinneret holes using computer-controlled image processing.

Automatic Defect Handling: Unqualified holes are recorded, can be cleaned with compressed air, or marked using a coaxial light source.

Full Automation Definition: The microscope automatically inspects and records position coordinates of each hole, including abnormal holes. Air blow cleaning and visual marking ensure precise defect management.
