Problems solved by technology

Due to the non-planarity of the detection object and the high reflection of the surface, the traditional machine vision detection system is difficult to meet its requirements. Therefore, at present, the detection of surface defects on automotive plastic interior parts still mainly relies on manual detection, and its detection efficiency is low. Poor accuracy, often difficult to meet the actual requirements of modern industrial production

Abstract

The invention relates to an online detection device for flaws on a smooth surface of a nonplanar plastic. The device comprises a computer system, an imaging system and a movable electric control loading system, wherein the movable electric control loading system is used for positioning a detected object, and rotating by angles so as to clearly image the flaws on the smooth surface of the detectedobject; the imaging system is used for acquiring an image of the detected object; the computer system is used for controlling the imaging system and the electric control loading system and detecting the image obtained by the imaging system. The invention also relates to an online detecting method for the flaws on the smooth surface of the nonplanar plastic. The device and the method have the characteristics of being convenient to detect, fast, and high in stability; and the flaws on the smooth surface of the nonplanar plastic can be subjected to online detection and quality evaluation.

Description

technical field [0001] The invention relates to the technical field of surface defect detection of automotive plastic interior parts, in particular to an on-line detection device and method for non-planar plastic smooth surface defects. Background technique [0002] With the progress of society and the rapid development of our country's national economy, China's auto industry has made rapid progress. At the same time, with the development of the plastics industry, plastic products are increasingly popular and widely used in the automotive industry. As one of the important parts of automobiles, automotive plastic interior parts have certain strength and toughness, can be repeatedly processed, are resistant to oil and dirt, and are low in price. Their advantages are incomparable to other decorative materials. It improves the commodity value and market competitiveness of automobiles, and plays an important role in model competition and market development. Therefore, improving ...
