AI Technical Summary

Technical Problem

Existing technologies cannot effectively determine whether the polyethylene film in carbon fiber prepreg has been completely peeled off, which affects the molding quality of carbon fiber composite materials.

Method used

By acquiring images of the carbon fiber prepreg to be inspected, dividing them into several inspection areas, calculating the average pixel value of each area, determining whether the polyethylene film has been completely peeled off based on the pixel value, and using a robotic arm and vision sensors for automated peeling and inspection.

Benefits of technology

This technology enables accurate determination of the peeling state of polyethylene film, improving the molding efficiency and quality of carbon fiber composite materials.

Abstract

This invention relates to the field of carbon fiber technology, and particularly to a method and apparatus for detecting the peeling of polyethylene film from carbon fiber prepreg. The method includes: acquiring an image to be inspected, including the polyethylene film; dividing the image to be inspected into several regions to be inspected; wherein adjacent regions overlap, and the area enclosed by all regions to be inspected covers the area of ​​the polyethylene film; calculating the average pixel value of each region to be inspected; and determining, based on the average pixel value of each region to be inspected, whether the polyethylene film in the carbon fiber prepreg has been completely peeled off. The solution of this invention can determine whether the polyethylene film has been completely peeled off from the carbon fiber prepreg.
