A three-dimensional rapid online quality inspection system for steel plates

Abstract

The invention discloses a rapid on-line quality inspection system for three-dimensional dimensions of steel plates, comprising a steel plate transport device for transporting steel plates to other devices; Find the design size information of the steel plate; the first measuring device is used to measure the thickness data of the steel plate; the second measuring device is used to comprehensively scan the steel plate and collect the point cloud data information of the steel plate; the data storage and display control device is used for The point cloud data is processed, the geometric parameters of the steel plate are calculated, and it is also used to judge whether each data does not meet the corresponding standard requirements according to the preset judgment rules, and display and transmit all the above data. The invention can realize automatic detection in the harsh environment of the steel mill, improve the detection accuracy, reliability and factory production rhythm, ensure the detection quality of the ex-factory products, at the same time reduce the number of production line workers, reduce the labor intensity of the workers, and reduce the damage to the human body caused by the operating environment.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, in particular to a three-dimensional rapid online quality inspection system for steel plates. Background technique [0002] At present, steel plate inspection is mainly done manually. The length and width of the steel plate are measured by a meter ruler, and the thickness of the steel plate is randomly checked by a micrometer. The records are recorded on the surface of the steel plate and then entered into the computer. The accuracy of the measurement depends heavily on the experience and responsibility of the inspectors. The measurement error is relatively random, and the steel plate is generally not a standard rectangle due to factors such as rolling and shearing. Workers can only detect the length, width and thickness of the fixed position of the steel plate, and cannot find the minimum width, length and thickness required by the national standard. Thickness values, there are false...
