Background In the field of automated processing of precision hardware, the production of fasteners such as ring groove rivets typically involves multiple processes such as integral forming, ring groove machining, and thread turning. In order to improve the production efficiency and consistency, a multi-station automatic processing device has become a mainstream choice in industry. In the process, the nail cap and the nail rod are turned or punched into a whole, then the annular groove is machined, and finally the screw thread is turned on the surface of the nail rod. However, after the ring groove machining is completed, the bulk rivets are typically collected by a hopper and passed into a subsequent thread machining unit. However, the direction of the head end and the rod end of the rivet, which is collected by the hopper and conveyed by the vibration plate, is random, and the rivet does not have direction consistency. The subsequent thread turning process has extremely high requirements on the clamping and positioning of the workpiece, and it is necessary to ensure that all rivets are accurately clamped on the fixture in a uniform direction. In the prior art, the initial sorting is performed by combining the vibrating disk with a simple rail, but for workpieces with obvious structural differences at two ends and special gravity center distribution like ring slot rivets, the traditional vibrating disk is difficult to realize tight and accurate direction unification. The rivets which inevitably have wrong directions enter the conveying line, so that the rivets appear in an automatic clamping station, the thread processing quality is affected, and even waste products are generated. Based on the above, there is a need for further improvements in the art.
