Method for detecting quality of flanges

Abstract

The invention discloses a method for detecting quality of flanges. The method comprises manual initial detection and picture comparison detection, wherein the manual initial detection is mainly used for detecting substandard products easy to recognize; according to picture comparison detection, taken pictures of the rest flanges are in comparison with the standard picture saved in a system in advance to detect whether the contact ratio of the taken pictures and the standard picture is lower than 95% or not, if the contact ratio of the taken pictures and the standard picture is lower than 95%, the flanges are defective, are inferior-quality products, and need to be processed again, and if the contact ratio of the taken pictures and the standard picture is higher than or equal to 95%, the flanges are qualified products, and can enter the follow-up marketing step. According to the method for detecting quality of the flanges, a manner of combining the manual initial detection and picture taking comparison precise quality detection is adopted to remove the unqualified flanges, so that the outgoing quality of the flanges are ensured, the reputation and economic benefits of a manufacturer are maintained, good application prospects are achieved, and the method is worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of flanges, and in particular relates to a method for detecting the quality of flanges. Background technique [0002] At present, large-scale projects in the society need to use various equipment, and the coordinated operation of various equipment can ensure the smooth completion of large-scale projects. The connection between various large-scale equipment often needs to be fixed by using flanges. Therefore, The quality of the flange is greatly related to the smoothness of the entire project. At present, there are many types of flanges on the market, and there is no complete detection system. Therefore, this part needs to be studied. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the present invention provides a method for testing the quality of flanges, which uses a combination of manual preliminary quality inspection and photographic comparison of fine quality ins...
