Online detecting device and method for inner wall of vessel

Abstract

The invention provides an online detecting device and method for the inner wall of a vessel. The online detecting device comprises a camera, an adapter lens, a rigid endoscope, a rotating platform and an image analysis device, wherein the camera is used for presenting images of the inner wall of the vessel, which are obtained by the rigid endoscope; the adapter lens is connected with the camera and the rigid endoscope; the rigid endoscope is inserted into the vessel to be detected to acquire the images of the inner wall of the vessel; the rotating platform is used for carrying the vessel to be detected and driving the vessel to be detected to rotate; the image analysis device is used for analyzing the sequential images of the inner wall of the vessel, which are presented through the camera, and acquire a detected result. Through the online detecting device and method for the inner wall of the vessel, provided by the invention, 360-DEG dead-angle-free images of the inner wall of the vessel can be precisely obtained, the online detection of the inner wall of the vessel can be realized, unqualified products can be rejected from a production line, and the online real-time detecting requirement can be met. The method has very strong adaptability, can be widely applied to the online detection for the inner walls of transparent or nontransparent vessels and can be used for improving the automation level of the production line and reducing the probability that inferior-quality products flow into the market.

Description

technical field [0001] The invention relates to the technical field of industrial automatic detection, in particular to an online detection device and method for the inner wall of a container. Background technique [0002] The diversification of modern industrial products puts forward higher requirements for packaging containers, and packaging container inspection has become an important link in the automated production line. Packaging container inspection can be divided into offline sampling inspection and online inspection. Offline sampling inspection mainly refers to random sampling of samples on the production line for inspection. The speed is slow and cannot represent the actual inspection situation of the production line. At present, the online inspection of packaging containers on the production line mainly relies on manual inspection. If a packaging container is found to be unqualified, it will be manually removed from the production line. In manual testing, there a...
