The inspection of the external dimensions and structure of cables and wires is a major inspection item in the quality management of cables and wires, which can be divided into: appearance inspection, dimensional measurement and structural inspection.
Visual inspection is to ensure that the surface is smooth and clean, and free from defects and impurities such as burrs, cracks, spots, and oil stains that could affect normal operation.
The dimensional inspection of wires and cables includes the inspection of outer diameter, eccentricity, pitch, cross-section and density.
Structural inspection includes cross-section inspection, sheath inspection, cable core structure inspection, and insulation core inspection. It is a final inspection combining visual and dimensional checks to ensure that the appearance is free of defects and the dimensions are accurate.
Xi'an Huode's cylindrical appearance defect detection adopts an intelligent vision inspection method, which can effectively detect the appearance of moving wires and cables online with an accuracy of 0.02mm, realizing real-time monitoring of every inch of appearance defects under high-speed production conditions.
Simultaneously, based on the detection requirements, the detection algorithm can issue alarms and store the information in the database for cable appearance defects according to their grade, product information, and other relevant descriptions, so as to meet the needs of future defect history retrieval.
