Product Specifications

Technical details and manufacturing context for Leather Surface Defect Detection System

Definition

The Leather Surface Defect Detection System is an industrial vision system designed for automated quality control in leather manufacturing. It scans leather hides and finished products for surface defects using high-resolution cameras and machine learning algorithms. The system identifies imperfections such as scars, scratches, color variations, and grain inconsistencies, and integrates with production lines to provide real-time quality assessment and sorting decisions. This reduces manual inspection labor and improves consistency in leather grading.

The system is built on an aluminum frame with optical glass lenses, copper wiring, steel mounting hardware, and silicone seals. It supports inspection widths from 1600 to 3200 mm, detects defects as small as 0.1 to 1.0 mm², and operates within a temperature range of 10 to 40 °C. Power consumption ranges from 2.5 to 5.0 kW, and the system can handle line speeds of 10 to 60 m/min while maintaining a detection accuracy of at least 99% for defects larger than the sensitivity threshold, with a false positive rate of 1% or less. It operates on a three-phase 380 V AC supply (±10%, 50/60 Hz) per IEC 60038, in non-condensing humidity of 20 to 80% RH, and offers ingress protection rated IP54 to IP65 per IEC 60529. Camera resolution ranges from 5 to 12 megapixels per camera, depending on width, and the machine weight is between 1500 and 3000 kg. The system can classify at least 10 defect types, including scratches, holes, and grain defects.

All listed parameters are reference ranges that must be confirmed for the specific model and application. Verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

High-resolution cameras capture leather surface images as the material moves through the inspection zone. The images are processed by computer vision algorithms that detect and classify defects based on trained models. The system then triggers sorting mechanisms to separate defective pieces from acceptable ones. The working principle relies on consistent lighting and camera calibration to ensure accurate detection.
