Problems solved by technology

[0002] The turbocharger turbine for vehicles is made of cast aluminum, and then partially turned. The surface often has defects such as trachoma, fleshy leaves, and leaf bends. It needs to be inspected after processing, but the current inspections are all through manual observation. Low work efficiency and high cost, especially the detection quality is unstable and non-standard, and there are problems such as missed detection and wrong detection

Abstract

The invention belongs to the field of machine vision detection, and particularly relates to an automatic detection line for turbine appearance defects, which is used for realizing automation and standardization of cast aluminum turbine appearance defect detection and greatly improving detection efficiency and quality stability. The machine comprises a machine frame, and the machine frame is provided with a conveying device used for conveying turbines, an installation detection device, a turbine upper portion defect detection device and a detection method, a turbine side face defect detection device and a detection method, a turbine lower face defect detection device and a detection method, a turbine circulating conveying line and a turbine detection sorting device. According to the method, the surface defects of the aluminum casting turbine are detected by comprehensively applying a traditional visual algorithm and a deep learning algorithm, the turbine can be detected in real time, the detection precision and accuracy are ensured, the method is very beneficial to product quality control, and the detection automation and speed are greatly improved.

Description

technical field [0001] The invention belongs to the field of machine vision detection, and in particular relates to an automatic detection line for turbine appearance defects. Background technique [0002] The turbocharger turbine for vehicles is made of cast aluminum, and then partially turned. The surface often has defects such as trachoma, fleshy leaves, and leaf bends. It needs to be inspected after processing, but the current inspections are all through manual observation. The work efficiency is low and the cost is high, especially the detection quality is unstable and non-standard, and there are problems such as missed detection and wrong detection. There is an urgent need to develop a simple, practical and automatic detection method and equipment for cast aluminum turbines. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention proposes an automatic detection line for turbine appearance defects, which real...
