The technical scheme of the invention is explained in detail with the accompanying drawings, and the invention provides a full-automatic piston ring flexible assembly detection device and a full-automatic piston ring flexible assembly detection method, which realize the automatic feeding of the piston, the automatic assembly detection of the piston ring, the automatic grouping blanking of the ring-loading piston and the like by arranging an automatic feeding device, an annular feeding channel, a lining ring assembly station mechanism, a doctor blade assembly station mechanism, an air ring detection station mechanism, a piston ring full-detection station mechanism, a feeding channel, an automatic grouping blanking device and the like, greatly improve the automatic level of the piston ring assembly, save the manual feeding link of the automatic feeding device, ensure the ring-loading quality of the piston by the real-time monitoring of the ring-loading detection station, realize the consistency of the piston information by the automatic grouping blanking of the piston ring, and realize the unmanned operation of the piston ring assembly by the whole full-automatic flexible assembly detection device, manpower and material resources are saved, and the assembly efficiency is greatly improved.

In the present invention, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; the term "plurality" means two or more unless expressly limited otherwise. The terms "mounted," "connected," "fixed," and the like are to be construed broadly, and for example, "connected" may be a fixed connection, a removable connection, or an integral connection; "coupled" may be direct or indirect through an intermediary. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
