Abstract

The invention provides a machine vision online detection system and method of an engine valve. The system comprises a conveying part, a sensing positioning part, a vision detection part and a control system, wherein the conveying part comprises a manual loading mechanism, a product dislocation mechanism, a clamping rotation mechanism, a product clamping and discharging mechanism and a ball screw moving platform; the sensing positioning part comprises a loading position photoelectric sensor, a rotation position electric sensor, a discharging position photoelectric sensor and multiple detection sensors; the vision detection part comprises multiple industrial cameras and a computer; the computer is connected with the industrial cameras; and the control system is connected with the conveying part, a sensing positioning part and the computer and used for controlling the actions of the conveying part, the sensing positioning part and the vision detection part. In the invention, online detection of the automobile engine valve can be realized, and low efficiency, high cost and high missing rate of manual detection are avoided.

Description

technical field [0001] The invention relates to the field of engine valve detection, in particular to a machine vision online detection system and method for engine valves. Background technique [0002] With the vigorous development of the automobile industry, customers' awareness and requirements for automobiles are getting higher and higher. In addition to factors such as appearance and shape, the quality of cars is increasingly reflected in safety, starting power, handling and other places. The engine valve is one of the key components of the automobile engine. The quality of the valve is directly related to the safety of the automobile, the engine power level and the overall quality of the automobile. The quality of the engine valve directly affects the performance of the automobile engine and the service life of the automobile engine. The traditional detection method of the small end face and size of the engine valve adopts manual detection. Since the small end face of...
