Visual inspection method for pipe joints

Abstract

The invention discloses a visual inspection method of pipe joints. Automatic pipe joint conveying is achieved well through a conveying line; in the conveying process, a borescopic inspection mechanismused for inspecting whether sundries exist in the pipe joints or not, an outer surface inspection mechanism used for inspecting the surface flatness of the pipe joints and a three-camera inspection mechanism used for inspecting whether the ends of the pipe joints are damaged by bumping or not and whether the inner walls rust or not are sequentially arranged; after the pipe joints are recognized as qualified products or inferior-quality products or waste, sorting and collecting can be achieved; mechanical automation is overall achieved, and device monitoring and controlling can be achieved through only one person; and manpower is effectively saved, quality testing efficiency and quality testing quality are improved, product quality can be improved easily, and economic benefits are guaranteed.

Description

technical field [0001] The invention relates to a workpiece detection method, in particular to a pipe joint visual detection method. Background technique [0002] In the prior art, the quality inspection of water pipe joints is mostly directly judged by the naked eyes of the quality inspectors, and its accuracy is not guaranteed. Due to naked eye errors or long-term quality inspection fatigue, it is easy to miss defective products, which is not conducive to maintenance. product quality. In order to solve the problem of artificial errors, more visual inspection equipment is now used. After the water pipe joint is placed on the visual inspection equipment, the external and internal conditions of the water pipe joint are photographed by cameras and other equipment, and then compared with the standard parameters. Comparing, if the parameters are met, it is a qualified product, and the unqualified product is a defective or waste product. The defective product is collected for re...

Problems solved by technology

However, because the water pipe joints need to detect the parameters of multiple positions, multiple visual inspection devices are required to be used together; the process of transferring the water pipe joints needs to be manually implemented, which is inefficient; Misplacement of products may occur, confusing qualified products, defective products and waste products, resulting in unnecessary duplication of work, and even late defective products flow into the market, causing losses to the enterprise
