3. The camera utilizes a high-frame-rate, high-resolution monochrome industrial camera, ensuring undistorted image capture and thereby guaranteeing measurement accuracy.

4. The machine employs high-strength metal loading fixtures and a work surface, offering excellent load-bearing capacity and facilitating easy replacement of spinneret fixtures. (Machined via grinding to ensure flatness).

5. Equipped with a display monitor for convenient observation of the testing process and progress.

② Electrical System Overview

1. Utilizes reliable image processing algorithms to detect microhole parameters including diameter, area, roundness, and contamination rate (specific parameters customized per client requirements), automatically recording locations of non-compliant microholes.

2. Spinneret template calibration files are configured by users inputting spinneret parameter settings.

3. Lenses feature auto-focus functionality to enhance inspection efficiency.

4. Test data is stored in a database for convenient recording and analysis.

5. Optimized algorithms and path planning increase single-hole detection speed to approximately 0.2-0.7 seconds per hole. Detection rate varies based on spinneret specifications (directly related to hole pitch).

6. Flexible operation allows detection of different spinnerets by simply loading corresponding template files.

7. Equipped with an original Advantech industrial control computer featuring X, Y, Z axis control cards, I/O cards, and an adjustable light source controller. Includes an industrial control computer keyboard and mouse for rapid data transmission.

8. Features a long-life LED bottom light source and a full-coverage spinneret loading fixture. The light source uniformly illuminates the spinneret's micro-holes, enabling the lens to capture and display high-quality images on the monitor.

9. Incorporates an integrated design for enhanced aesthetics. Utilizes high-strength metal loading fixtures and work surfaces, offering excellent load-bearing capacity and convenient spinneret fixture replacement.

Applications

The Spinneret Inspection Microscope is an instrument used to detect the size of spinning holes and whether they are blocked in various types of chemical fiber spinnerets (spinning plates or spinneret plates).

The instrument automatically performs a “comprehensive examination” of all spinneret holes, including: - Automatic recording of each hole's position coordinates - Inspection and recording of coordinates for abnormal holes - Manual handle operation for air-blow cleaning during abnormal hole clearance - Localization via coaxial light beam projection onto spinneret micro-holes or stamp marking for non-compliant holes.

Common types of synthetic fibers include industrial yarns, turf yarns, island fibers, BCF, POY, DTY, specialty fibers, carbon fibers, aramid fibers, and nylon (polyamide). This inspection system measures conventional spinneret micro-hole diameter, area, roundness, contamination rate, and qualification status. Customized micro-hole inner wall tomography scanning functionality is also available.

Features

Intelligent Automation: You only need to load the spinneret and set the parameters; the system handles auto-focus, coordinate tracking, and hole-by-hole scanning without manual intervention.

Tomographic Scan Mode: Unlike standard surface inspections, this system offers a "fault scanning" feature. It divides the capillary length into multiple zones to detect internal fouling that surface depth of field might miss.

Integrated Remediation: The system provides built-in tools for immediate action, including air-jet cleaning for blockages and stamp marking or coaxial light targeting for failed holes.

Dual-Interface Analysis: You can toggle between a raw Data Interface for numerical analysis and a Graphical Interface for real-time visual inspection of the hole's physical state.

Robust Industrial Build: Designed as an all-in-one unit with an integrated Advantech industrial computer and a high-strength metal fixture table to ensure vibration-free, precision movement.

Test Procedures

Inspection Process:

Place spinneret plate → Set parameters → Auto-focus positioning → Automatic hole-by-hole scanning inspection with simultaneous generation of inspection data and images → Automatic microhole detection → Automatic cleaning or automatic marking (manual processing also available) → Inspection complete

Inspection Methods:

1. Utilizes computer control and image processing technology for automatic hole-by-hole scanning inspection and recording of test results.

2. For non-compliant spinneret pinholes, the instrument automatically records and offers air-blow cleaning or stamp marking functions. A coaxial light source can indicate the location of pinholes that remain non-compliant after automatic cleaning.

3. The software includes 5 built-in inspection modes (Inspection → Air-Blow → Re-inspection → Marking → Tomography Scan), selectable based on actual testing requirements.

Inspection Items:

1. Microhole diameter, area, roundness, contamination rate, qualification status, and dimensions of special irregular holes. Users can define judgment criteria within the program to determine microhole qualification, excessive/insufficient area, and compliance with preset ranges. Non-compliant data is highlighted with distinct colors.

2. The instrument features dual interfaces: a data interface displaying comprehensive microhole inspection metrics and a graphical interface providing real-time visual feedback on hole conditions.

3. Equipped with aperture measurement functionality, serving as a basis for spinneret filament inspection. Spinneret data can be directly saved to a computer.

4. The inspection system incorporates a tomographic scanning function to automatically scan for internal contamination within the holes. Conventional rapid inspections, constrained by depth of field limitations, only reveal the surface cleanliness of spinneret micro-holes, failing to provide comprehensive insights into contamination along the entire length of the spinning holes. To address this, our company has optimized the software algorithm. Utilizing the tomographic scanning detection mode, the spinneret's spinning hole length can be divided into multiple sections for inspection, with contamination values listed for each segment.
