Imaging device and imaging method for detecting surface defects of cylindrical workpieces

Abstract

The invention discloses an imaging device for detecting surface defects of cylindrical workpieces. The imaging device comprises an inclined plane (1) and a cylindrical surface high-speed imaging camera (2), wherein the cylindrical surface high-speed imaging camera (2) is placed at the upper side of the inclined plane, and the viewing direction of the cylindrical surface high-speed imaging camera (2) is vertical to the inclined plane (1); the inclined plane (1) is provided with a plurality of support scroll bars (6) distributed up and down along the inclination direction of the inclined plane; under the effect of driving parts, the support scroll bars (6) synchronously rotate in the same direction, and every two adjacent support scroll bars (6) support rolling of one cylindrical workpiece. Two support scroll bars are utilized to support rolling of one cylindrical workpiece, and automatic gliding of the cylindrical workpieces is realized by use of the inclination angle of the inclined plane, surfaces of the multiple rolling and gliding cylindrical components can be imaged in one step, and the surface defects of the multiple arrayed cylindrical workpieces can be rapidly and efficiently detected. The invention also discloses an imaging method adopting the device.

Description

technical field [0001] The invention belongs to the technical field of workpiece surface imaging detection, and in particular relates to an imaging device and an imaging method for detecting surface defects of a cylindrical workpiece. Background technique [0002] The quality inspection of industrial products is an important production link. Traditional online inspection often needs to be done manually. Due to the high cost and low efficiency caused by manual inspection, in recent years, machine vision inspection has become more and more popular with its high efficiency, intelligence and high cost performance. Features, gradually replaced the manual detection, widely used in industry. The surface defect detection of cylindrical components based on machine vision was produced under this technical background. However, efficient imaging of the surface of cylindrical components has become a key technical problem. At present, most of the existing automatic cylindrical workpiece ...

Problems solved by technology

At present, most of the existing automatic cylindrical workpiece detection and imaging devices use the rotating platform to drive the workpiece to rotate 360° to continuously collect images to complete the work, but this detection method can only detect one workpiece at a time, which is low in efficiency and cannot be completely replace artificial
