Machine vision detection workbench

The invention relates to the technical field of machine vision teaching, in particular to a machine vision detection workbench. Comprising a metal plate workbench, and an appearance detection module, a conveying line module, a quick-change tool module, an electromagnetic valve group, a robot module, a material defect detection module, a three-color lamp assembly, a computer, an operation control module, a character detection module, a circuit module, a two-dimensional code recognition and size detection module and a visual positioning drawing module which are arranged on the metal plate workbench. Based on the four functions of visual mode recognition, visual positioning, size measurement and appearance detection of machine vision, electrical circuit personalized design is carried out at the same time, unit circuit control and gas circuit connection plug-and-play are achieved, cognitive learning of circuits and gas circuits by students is increased, and the learning efficiency is improved.
