Abstract

A chemical fiber spinneret hole shape precise detecting device based on machine vision comprises an installing cabinet. The installing cabinet comprises a cabinet body and an L-shaped plate which areof a split type structure or integrated type structure. The top face of the cabinet body is provided with a detecting and carrying platform located on the lower side of the horizontal portion of the L-shaped plate. A positioning block for positioning a spinneret is arranged on the detecting and carrying platform. The bottom face of the detecting and carrying platform is provided with a lighting and illuminating mechanism for providing a light source and making the light source perpendicularly pass through a spinneret hole right from the lower side. The top face of the detecting and carrying platform or the vertical portion of the L-shaped plate is provided with an image collecting mechanism for taking images of the plane where the spinneret hole is located through an industrial camera anduploading the collected images to a computer to be processed. The cabinet body is internally provided with the lighting and illuminating mechanism, a host of the computer and an input device. The vertical portion of the L-shaped plate is provided with a computer display screen for presenting a detecting interface and a detecting result. The precise detecting device is high in detecting efficiencyand can detect one spinneret hole every 3 seconds at most without being influenced by hole number and aperture changes.

Description

technical field [0001] The invention belongs to the field of hole defect detection, and in particular relates to a machine vision-based precision hole shape detection device for a chemical fiber spinneret. Background technique [0002] The spinneret is a precision part on the chemical fiber spinning machine, also known as the spinneret. During the process of manufacturing and spinning, it is easy to have defects such as clogging, burrs, and out-of-roundness. The quality of its state will directly affect the spinning Quality is an important quality goal of enterprise control. [0003] Due to the small diameter of the spinneret hole (micron level, 40μm-85μm) and the large number of holes (24-120), the traditional detection method in the industry is still to manually rotate the spinneret under a microscope, and use the naked eye one by one. Observational inspection, the detection time is 5-10 seconds / piece (depending on the aperture and number of holes). This detection method...
