Abstract

The invention discloses a rivet quality rating and automatic sorting system, which includes a material conveying device, a detection device, a screening device and an automatic control unit; the material conveying device transports rivets for the detection device, and outputs the rivets after detection to the screening device; The detection device includes a clamping mechanism and an information collection mechanism. After the rivet is clamped, the rod electronic ruler measures the diameter of the rivet rod, the camera collects the image of the rivet, and the industrial computer classifies the quality grade of the rivet according to the diameter of the rivet rod combined with image processing technology The results are recorded and transmitted to the screening device; the screening device includes a sorting tank and a sorting bucket, and the sorting tank is rotated according to the rivet quality grade division results, and the rivet is transported to the sorting bucket of the corresponding grade. The invention adopts the method of combining the rod electronic ruler and the image processing technology to effectively improve the detection accuracy, can select different evaluation standards, complete the quality rating and automatic sorting of various types of rivets, and has high work efficiency.

Description

technical field

[0001] The invention relates to the technical field of parts automatic detection, in particular to a rivet quality rating and automatic sorting system and method. Background technique

[0002] A rivet is a standard fastener used for cold joining of parts. It is widely used in aviation, railway, ship and other equipment. If the rivets in the equipment loosen or break due to quality problems, the connected parts will be loosened, resulting in serious accidents. Therefore, the quality of the rivets is directly related to the performance and safety of the equipment. The quality of rivets is reflected in two aspects of size and surface defects. figure 1 Shown is a common countersunk head rivet. The size of the rivet mainly includes the taper angle of the countersunk head, the outer diameter of the top surface, the thickness of the head, the length of the rivet, and the diameter of the rivet shaft. Among them, since the rivet rod is in contact with the connecte...
