Problems solved by technology

However, for the ever-changing coil shape during production, there is no online strip edge depth detection device to detect it, so that the strip edge depth cannot be quantified, resulting in no effective data support for subsequent analysis to solve the coil quality problem

Abstract

The invention provides an online detection device for misalignment of band steel in coiling and a detection method. The device comprises a line structural light emitter for projecting line structural light to a detected steel coil, an image acquiring unit for acquiring line structural light reflected by the surface of the steel coil, and an image processing unit for processing the line structural light and acquiring the misalignment depth of the band steel. With the adoption of the device and the method, the problem that the misalignment depth of the band steel in coiling by a coiling machine cannot be measured in real time is solved; the misalignment height of the band steel can be detected on line and in real time when the band steel is coiled by the coiling machine on the premise that the coiling production conditions are not influenced; the device is safe, reliable, and high in accuracy; effective data support is provided to analyze and solve the problem of coil shape quality in later period; and the coiling machine is assisted to reduce the misalignment depth of the coiled band steel.

Description

technical field [0001] The invention relates to the field of measurement, in particular to an on-line detecting device and a detecting method for the misalignment amount of strip steel coils. Background technique [0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel is generally supplied in coils, with high dimensional accuracy, good surface quality, and convenient Processing, material saving and other advantages, during the coiling process of steel coil, the strip steel deviates and forms a jagged edge, which is called the wrong side. An important indicator of product appearance quality assessment for coil delivery to users, there are clear quantitative regulations in the inspection regulations and standards for rolled steel (coil) strips. Exceeding the standard misalignment depth will bring many p...
