A conveyor belt is provided inside the table top, and the conveyor belt conveys the conveying flange. A support frame is provided in the middle of the table top, and the support frame is composed of a crossbeam and a vertical frame. A fixed seat is provided on the crossbeam, and a first camera is provided at the front end of the fixed seat, and a second camera is provided to the right of the first camera. The flange visual inspection device described in the utility model, with three cameras cooperating, can detect whether the screw hole on the flange has threads and measure whether the minor diameter of the screw hole is within the specified range. It has the advantages of high efficiency, high precision and large working range. At the same time, by providing an electric telescopic rod, the screened defective products can be pushed into the collection box for centralized processing, replacing manual inspection in the actual production process, and achieving a significant improvement in production efficiency. However, the problem with the above technical solution is that it is unable to automatically detect the back side of the flange. Specifically, if the back side of the flange is also provided with threads, the flange that has been inspected from the front side needs to be manually turned over and placed back on the equipment for inspection, which results in a relatively low inspection efficiency on the back side of the flange. Therefore, it is necessary to solve the technical problem of how to quickly inspect the other side of the flange. Therefore, there is a need to provide a double-sided ground flange defect detection device based on visual inspection, which can inspect both sides of the flange, has high practicality and is convenient to inspect.
