Abstract

The invention discloses a cylindrical metal surface defect detection device based on machine vision. The device comprises a base, wherein a support column is fixedly mounted on the base, a screw rod is rotatably mounted in the support column, a screw rod seat of the screw rod is fixedly connected with a fixed plate, and a detection camera is fixedly mounted on one side of the fixed plate; a secondgroove is formed in the base, a first spring is fixedly installed in the second groove, one end of the first spring is fixedly connected with a second connecting plate, and a cushion block is fixedlyinstalled on the second connecting plate. The device is simple in structure and convenient to operate, facilitates continuous feeding of to-be-detected cylindrical metal, improves the continuity of the detection process, improves the detection efficiency to a certain extent, reduces vibration generated during operation of the device, reduces the influence of vibration on the detection process toa certain extent, and improves accuracy of a detection result.

Description

technical field [0001] The invention belongs to the technical field of defect detection, and in particular relates to a machine vision-based cylindrical metal surface defect detection device. Background technique [0002] The metal surface defect detection device is a machine vision system composed of a high-speed line array camera and an image processing system. It is widely used in the automatic inspection of various metal surfaces. Automation, improve product quality, increase production efficiency, reduce labor costs, reduce defective rate, and now the metal surface defect inspection system has been widely used in metal manufacturing, processing and other industries. [0003] However, in the prior art, when detecting defects on a cylindrical metal surface, it is not convenient to detect the side of the cylinder because the side of the cylinder is a curved surface, and the continuity of the detection process is not high, which reduces the detection efficiency. During the...
