Vision Length Measurement System | Non-Contact Online Metering & AI Defect Inspection
CCD Machine Vision + Precision Metering + AI Defect Detection. ELE all-in-one vision length measurement system solves three core production pain points for roll material manufacturing lines: inaccurate length counting, manual missing defects, and insufficient quality traceability. Widely applicable to textiles, chemical fibers, cables, plastic films, metal strips, and paper industries, this intelligent visual inspection equipment replaces traditional contact encoders and manual visual inspection, helping enterprises achieve precision production, standardized quality control, and full-process data traceability.
Traditional contact wheel counting and manual inspection can no longer meet modern factories’ requirements for high precision, high speed, zero-defect production, and intelligent management. As a professional industrial vision inspection manufacturer, ELE independently develops vision-based length measurement systems to realize non-contact metering, full online defect detection, and cloud data traceability, effectively reducing production costs, improving overall efficiency, and eliminating quality dispute risks.
01.Eliminate Traditional Defects, Redefine Industrial High-Precision Metering
Hidden Drawbacks of Traditional Contact Counting Equipment
Most conventional length counters rely on encoder and contact wheel friction measurement. After long-term continuous operation, mechanical slippage, roller wear, and structural loosening inevitably occur, resulting in accumulating measurement errors over time. This long-standing problem leads to inconsistent finished material length, raw material waste, inaccurate delivery metering, and even customer reconciliation disputes, return claims, and corporate reputation losses.
Core Advantages of ELE Non-Contact Vision Metering System
Breaking the limitations of mechanical contact measurement, the ELE intelligent vision length measurement system adopts CCD linear scan industrial camera + high-precision image analysis algorithm. It captures real-time surface texture features and tracking points of rolling materials without any surface contact, realizing dynamic high-precision length calculation.
With zero friction and zero wear throughout the whole process, there is no slippage error or mechanical aging drift. The measurement accuracy is stably controlled within ±0.1% permanently, completely solving the accuracy attenuation problem of traditional devices. Every roll of material achieves true, reliable, and traceable length data.
02.All-in-One Design | One Device Covers Three Core Production Functions
Abandoning the traditional single-function single-device redundant configuration, the ELE vision system integrates precision length metering, AI full-scale defect detection, and cloud quality traceability in one unit, comprehensively upgrading and replacing backward production and inspection modes.
Comparison Item | Traditional Production Mode | ELE Visual Intelligent Solution |
Length in meters | Encoder contact counting, prone to slippage and wear; errors gradually accumulate with usage time. | Pure optical non-contact measurement; lifelong zero wear; accuracy always stable at ±0.1%. |
Defect Detection | Manual visual inspection with low efficiency and severe visual fatigue; extremely high missing and misjudgment rates. | 100% full online CCD scanning + AI intelligent classification identification; accurate capture of tiny defects. |
Quality Traceability | No effective data retention; difficult quality problem verification; frequent after-sales disputes. | Independent inspection report for each roll; cloud data storage; full-process quality traceability. |
03.Core Industry Applications | First Choice for Textile Intelligent Upgrade
Rolled textile materials represent the largest automated inspection demand scenario with the highest transformation return on investment. At present, China has more than 4,000 textile and nonwoven production lines, with an annual output of 8 million tons. However, the automated inspection penetration rate is only 15%–20%, and over 90% of production lines still rely on manual sampling inspection, resulting in high labor costs, unstable quality, and high defect rates.
3.1 Nonwoven Fabric Production Line
Installed at the winding station front end, the system realizes one-stop intelligent control for the entire production process:
- High-precision Metering: Millimeter-level visual counting eliminates slippage errors and material loss, supporting accurate output statistics and material consumption analysis.
- Full Defect Inspection: Automatically identifies holes, oil stains, crystal spots, lumps, wrinkles, uneven thickness and other common defects, with AI automatic classification and data statistics.
- Intelligent Alarm & Marking: Triggers sound-light alarm and automatic inkjet marking immediately after defect identification, facilitating precise cutting and rework in subsequent processes.
- Full Data Traceability: Generates exclusive quality inspection reports for each roll of material to realize visualized production management.
Core Value: Realizes 100% full coverage inspection instead of traditional 5% manual sampling rate, reduces missing inspection rate to nearly zero, and cuts customer quality complaints and return disputes by 80%.
3.2 Textile Printing, Dyeing & Finished Fabric
Covers the whole process from grey fabric weaving, printing and dyeing to finished product inspection. It accurately measures grey fabric length to optimize material utilization rate, tracks printing patterns in real time to ensure printing repeat precision, and intelligently detects finished fabric defects such as color difference, missing yarn, broken warp, and stains.
3.3 Synthetic Fiber & Yarn Industry
Realizes real-time monitoring of spinning density and uniformity dynamic feedback during high-speed production. It accurately identifies broken filaments for early warning, and precisely counts winding length to standardize finished yarn quality.
04.Universal Industry Adaptation | Full-Coverage Roll Material Inspection
Beyond textile scenarios, the ELE vision measurement and inspection system is widely applicable to almost all flexible and rigid roll material production lines:
- Cable & Optical Fiber Industry: Precise length metering + detection of surface scratches, bulges, and insulation damage defects.
- Plastic Film Industry: Suitable for BOPP, PE and other films, detecting crystal points, fish eyes, holes and other defects while counting length.
- Metal Strip Industry: High-precision metering for steel strips, copper strips and other metal coils, identifying surface scratches and indentation defects.
- Paper Industry: Base paper length measurement + detection of holes, impurities, and tearing defects.
- Rubber & Tire Industry: Precise cord fabric length counting + joint defect detection.
