The annular joint device comprises an outer-layer mirror, an inner-layer mirror, a first cylindrical laser input pipe and a first initial-section total reflection mirror, wherein the outer-layer mirror is formed through annular distribution of a plurality of total reflection mirrors, the inner-layer mirror is formed by through annular distribution of a plurality of half reflection mirrors, and the inner-layer mirror is arranged in an area defined by the outer-layer mirror. The outer-layer mirror andthe inner-layer mirror define an annular reflection area, the outer-layer mirror is provided with an opening in the circumferential direction, the first cylindrical laser input pipe communicates withthe reflection area at the opening, and is configured to convey wire harness laser, the first initial-section total reflection mirror is arranged in the annular reflection area, and the reflection surface of the first initial-section total reflection mirror is obliquely arranged at the opening and is arranged in the direction of the central line of the annular reflection area. The annular joint device can convert input wire harness laser into ring-shaped laser, is suitable for surface purification treatment of cylinders and irregular workpieces, is convenient to implement, and can save energy, and improve the cleaning efficiency, thereby achieving quick treatment and reducing energy consumption.
