Application research of infrared image processing technology in the quality inspection of riveting parts
Abstract
With the speeding up of the industrialisation process, lightweight products are more and more favoured by people, so the engineering plastic is born at the right moment. Engineering plastics are often used for structural materials in engineering. They have high mechanical strength, such as high temperature resistance, and are wear-resisting. With the development of engineering plastics, their advantages have been gradually accepted by people. In recent years, statistics shows that about 35% of the engineering plastics are used to produce auto spare parts. Using plastic products instead of tempered products is a trend of energy saving and environmental protection. However, there are some security risks such as the stability of the plastic riveting process. The quality of the product can be quickly detected by the artificial but some tiny product cracks are hard to detect. In order to make use of the plastic rivet products better, a product quality inspection system combining computer vision with infrared image processing technology is designed in the background of the hot riveting process of some automobile products. Firstly, this paper uses the infrared detector for image acquisition, then the digital images are obtained through the analogue digital conversion circuit.
