Online injection product quality detection device and method based on infrared imaging

Abstract

The invention discloses an online injection product quality detection device and method based on infrared imaging. The device comprises an infrared detection and acquisition module, an image displaying and processing module and a process parameter regulation module which are in telecommunication connection in sequence. The method comprises the following steps: performing all-round detection and thermal image acquisition on injection products through the infrared detection and acquisition module in the injection molding process, and transmitting the acquired images to the image displaying and processing module through a wired network; inputting the processed image data into a knowledge base, wherein the knowledge base is capable of analyzing various quality indexes of the products according to the image information, such as internal histological morphology and structure of the product, density of the product, defect conditions of the products and the like; and transmitting the quality parameters to the process parameter regulation module so as to realize online regulation of injection molding process parameters. According to the device, the quality problems caused in the injection product production process can be monitored in real time, closed-loop control from the quality indexes to the process parameters is realized, and the quality of the injection products is improved.

Description

technical field [0001] The invention relates to the field of manufacturing special equipment for plastic processing, in particular to an infrared imaging-based online quality detection device and method for injection molded products. Background technique [0002] Injection molding is one of the most common molding methods for plastic products. In recent years, with the application of injection molding products in high-tech fields such as aviation, aerospace, and communication products, people have higher and higher requirements for the quality and performance of injection molding products. As a result, there are higher requirements for the molding process monitoring and control technology. However, the current quality inspection method is mainly manual inspection, the degree of automation is not high, and the inspection efficiency is low; the quality control after the product comes out of the mold is still an open loop, and there is no automatic feedback of product quality i...
