Machine visual on-line detection method and equipment for tank cover quality in high-speed production line

The invention discloses machine visual on-line detection method and equipment for the tank cover quality in a high-speed production line. The method comprises the following steps of: in an automatic production line, separating tank covers to be detected into single tank covers moving on a delivering device; imaging the tank covers by using an imaging system at a high speed when the tank covers move to a detection station of the delivering device; transmitting an acquired tank cover image to an industrial computer for processing; carrying out quality detection on a plurality of detection areas to generate quality detection signals; eliminating unqualified products by using an eliminating device positioned at the eliminating station of the delivering device; making the qualified products continuously move on the delivering device and pass through a shaping device and outputting the qualified products in sequence. The equipment comprises a cover feeding device, the delivering device, the shaping device, the eliminating device, the imaging system, the industrial computer and an electric control system. The invention has the advantages of simple and compact structure, low cost, simple and convenient operation, high precision, high detection speed and the like.
