Description

Technical Field

[0001] This utility model relates to the field of hot-rolled stainless steel surface defect detection technology, specifically an adjustable hot-rolled strip surface oxidation defect detection device. Background Technology

[0002] Hot rolling refers to rolling steel above its crystallization temperature. Due to its lower energy consumption, higher metal plasticity, and improved processing properties of metals and alloys, hot rolling is widely used in steel production. On a hot rolling production line, large quantities of steel slabs are extracted from the heating furnace and processed throughout the entire line. Because the rolling process is complex, the operation and equipment status of each step affect product quality, often resulting in surface defects. These surface defects are a significant factor affecting the surface quality of both cold-rolled and hot-rolled strip steel, requiring timely detection. Current image recognition detection methods for hot-rolled strip steel surface defects primarily use CCD cameras to continuously scan the strip surface. Image processing technology then processes the scanned images in real time, enabling online detection and identification of surface defects. This is the most advanced and practical method in the field of online surface defect detection for cold-rolled strip steel.

[0003] Most existing surface defect detection devices for hot-rolled strip steel are designed to detect defects on the upper surface of cold-rolled stainless steel strip steel. They cannot be directly applied to the detection of the lower surface. Manual sampling or reinstallation of CCD camera brackets adapted for lower surface detection in other locations is required. This necessitates the installation of multiple sets of detection equipment adapted for both upper and lower surface defects at different locations during the strip steel production process, requiring multiple backup detection brackets and wasting materials, manpower, and resources.

[0018] This embodiment provides, for example Figure 1-6 An adjustable hot-rolled strip surface oxidation defect detection device is shown, comprising a detection body 1 and a detection camera mounted on the bottom of the detection body; the detection body 1 includes a strip conveyor belt 101, an adjustment ring frame 102 is mounted at the middle gap of the strip conveyor belt 101, the outer wall of the adjustment ring frame 102 is provided with adjustment grooves 103 around its perimeter, and the outer wall of the adjustment grooves 103 is provided with toothed grooves 104 around its perimeter; a connecting frame 105 is fixed to one inner wall of the adjustment ring frame 102, and extension frames 106 are fixed to both sides of the connecting frame 105, with four sets of screws 107 passing through the end of the extension frame 106; a detection adjustment platform 108 is provided at the bottom of the adjustment ring frame 102, a sliding cavity 109 is provided at the center of the detection adjustment platform 108, and a drive frame 110 is fixed to the bottom surface of the detection adjustment platform 108, with a drive gear 111 shafted inside the drive frame 110, and a drive motor 112 is connected to the shaft of the drive gear 111.

[0019] Furthermore, the adjusting ring frame 102 is attached to the bottom surfaces of both sides of the steel conveyor belt 101 via the connecting frame 105 and the two side extension frames 106, and the extension frames 106 form a detachable structure with the steel conveyor belt 101 via screws 107; the adjusting groove 103 is opened in a ring around the outer wall of the adjusting ring frame 102, and the toothed grooves 104 are evenly distributed around the outer wall of the adjusting groove 103; the detection adjusting table 108 forms a sliding structure with the adjusting ring frame 102 via the sliding cavity 109, and the detection adjusting table 108 is fixedly connected to the drive frame 110; the drive gear 111 forms a rotating structure with the drive frame 110 via the drive motor 112, and one side of the outer wall of the drive gear 111 meshes with the outer wall of the toothed grooves 104; the inner wall of the detection adjusting table 108 is fixedly connected to the detection camera 2, and the curvature of the detection adjusting table 108 and the inner sliding cavity 109 matches the curvature of the adjusting ring frame 102.

[0020] The detection device provided in the above embodiment mainly consists of an annular adjustment ring frame 102, a mounted detection adjustment platform 108, and a detection camera 2. The detection adjustment platform 108 can be adjusted annularly by the drive gear 111 inside the detection adjustment platform 108 engaging with the tooth groove 104 of the adjustment groove 103, allowing the detection adjustment platform 108 to slide annularly along the adjustment ring frame 102. This achieves the purpose of adjustment for different detection directions without the need for additional installation or replacement of supports at different angles, saving installation and operation time and improving convenience. Simultaneously, the adjustment groove 103 on the outer wall of the adjustment ring frame 102 of the detection device provided in the above embodiment provides stable sliding adjustment for the detection adjustment platform 108 and provides a limiting function during the adjustment process.
