Abstract

The invention relates to a light converter for the online detection of surface defects of automobile interior decorative parts, and the light converter is a multiple directional plane mirror group which consists of a plurality of plane reflectors, wherein the number of the plane reflectors is determined by the number of curved surfaces formed by the dividing of the surface of a detected object. The form of each surface of the detected object is corresponding to one independent plane reflector, and the posture of each plane reflector is changed to achieve the focusing of the reflected light ofdifferent surfaces on an imaging plane of a line scanning imaging system. The invention also relates to a design method for the light converter. The light converter can achieve the online detection imaging of the surface quality of a high-reflectivity and multi-curved-surface product.

Description

Technical field [0001] The invention relates to the technical field of on-line detection of surface defects of high-reflective, multi-curved surface automotive interior parts, in particular to a light converter and design method for on-line detection of surface defects of automotive interior parts. Background technique [0002] With the continuous improvement of science and technology and people's living standards, various plastic industrial accessories used in automobile and other interior decorations have been widely used and developed. Automobiles and other interior plastic parts can not only realize various complex curved shape workpieces and moldings through injection molding and other processing techniques, but also have the characteristics of high toughness, reuse, oil resistance, stain resistance, and low cost. Its advantages are unmatched by other decorative materials. . Plastic accessories can effectively improve the appearance and interior aesthetics of various indust...
