A Piston Rod Surface Defect Detection System

Abstract

The invention discloses a piston rod surface defect detection system, which includes a feeding mechanism, a transmission mechanism, a cleaning mechanism, a drying mechanism, an image acquisition mechanism, a sorting mechanism and a control module. The feeding mechanism sends the piston rod into the transmission mechanism , the piston rod of the transmission mechanism is transported to the sorting mechanism from left to right, the cleaning device cleans the pollutants on the surface of the piston rod passing under it, and the drying device dries the piston rod passing under it, and the image acquisition The mechanism obtains the image of the piston rod sent to the sorting mechanism and sends it to the control module. The image processing program is installed in the control module. The corresponding control signal generated by the judgment conclusion is sent to the sorting mechanism, and the sorting mechanism sorts the piston rod as a qualified product or a defective product; the advantages are high detection efficiency, low detection cost, and high detection accuracy.

Description

technical field [0001] The invention relates to a surface defect detection system, in particular to a piston rod surface defect detection system. Background technique [0002] The automobile shock absorber is a key component in the overall structure of the automobile. During the movement of the automobile, the automobile shock absorber is supported on the body and plays the role of vibration reduction. The quality of the automobile shock absorber determines the comfort and operation safety of the automobile. The piston rod is one of the most critical parts in the automobile shock absorber, its strength and surface quality determine the service life of the automobile shock absorber. The cylinder barrel of the automobile shock absorber is filled with hydraulic oil medium, and the piston rod moves up and down in the cylinder barrel. In order to prevent the leakage of hydraulic oil, the opening of the cylinder is sealed by the sealing ring to prevent the leakage of hydraulic o...
