Problems solved by technology
[0004] 1. Due to the existence of dust and other debris on the surface of the strip, errors in image features occur, which affect the detection results; if a dust removal component is installed, a separate drive device must be installed for the dust removal component, which not only increases the manufacturing cost, but also increases the occupied area
[0005] 2. The label at the unqualified position is pasted on the edge of the strip, which is convenient for the header to be exposed when the coil is rolled, and is easy to check. However, the existing detection equipment is prone to deviation when the coil is wound after the detection of the strip, causing the label to fall into the coil. inside of , cannot view

The invention relates to strip steel surface defect detection equipment which comprises a right-angle workbench, the lower surface of the right-angle workbench is fixedly connected with supporting legs, the inner wall of the right-angle workbench is rotationally connected with two rotating shafts used for installing coiled materials, and the inner wall of the right-angle workbench is rotationally connected with a first guide shaft; a fixing plate is fixedly connected to the inner bottom wall of the right-angle workbench, the same detector is fixedly connected to the upper surfaces of the fixing plate and the right-angle workbench, a limiting assembly is arranged on the inner bottom wall of the right-angle workbench, and a cleaning assembly is fixedly connected to the lower surface of the right-angle workbench. According to the device, a coiled material is placed through the rotating shaft, the coiled material is guided through the first guide shaft, the surface of strip steel is detected through the detector, a label is attached to an unqualified position, deviation of the strip steel during rolling is prevented through the limiting assembly, and the surface of the strip steel is cleaned through the cleaning assembly; therefore, the problems that the defect position label cannot be checked and dust affects the detection result are solved.
Description
technical field [0001] The invention relates to the technical field of testing equipment, in particular to a strip steel surface defect testing equipment. 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. The surface of the produced steel strip has more or less various defects, so In order to ensure the quality of the products, the surface of the steel plate must be inspected to ensure that the defects on the surface of the steel strip are detected in time and repaired in time. [0003] Strip steel surface defects are usually detected by a strip steel pinhole detector. The principle is to use a CCD camera to convert the detected target into an image signal and send it to a dedicated image processing system. Digitized signals, the image processing system performs various operations on th...
