Description

Technical Field

[0001] The present invention relates to the technical field of machine vision detection, and in particular to a high-temperature medium-thick steel plate contour detection device. Background Art

[0002] Hot-rolled steel plates are widely used in construction, automotive, energy, and machinery manufacturing, and are indispensable materials in many industrial fields. With the advancement of technology, the inspection accuracy requirements for thick and wide steel plates have become even higher, making the use of high-performance online inspection equipment extremely important.

[0003] Currently, some medium and heavy plate mills use profilometers with steel frames. Insulation panels near the steel plates are used to block high temperatures, and high-volume fans are used for cooling near the components. However, these simple insulation measures result in ineffective cooling. Consequently, existing technologies present the following challenges: 1. Insulation: Steel plates reach temperatures of around 1000°C, generating significant heat radiation that can easily damage components such as cameras, lenses, light sources, and lasers. 2. Cooling: Components such as cameras, light sources, and lasers operate 24 / 7, and their own long-term heat generation can affect their proper function. 3. Dust protection: Thermal radiation carries with it a significant amount of dust and oil vapor, which can easily adhere to components such as camera lenses and light sources, affecting image quality and ultimately inspection accuracy. 4. To capture the steel plate profile, the components must be mounted at a certain height, typically between 1.5 and 3 meters. The roller surface below is typically at least 0.8 meters above the ground. During maintenance, personnel must prevent the rollers from rotating and causing falls, creating significant safety hazards and inconvenient operation. Summary of the Invention

[0044] like Figure 6 As shown, the method for detecting the contour of a medium-thick steel plate using the high-temperature medium-thick steel plate contour detection device provided by the present invention comprises the following steps:

[0045] Step 1: The steel plate passes through the area array camera 29, the laser 7, the velocimeter 8, the line array camera 20, and the light source. The velocimeter 8 detects the speed of the steel plate, the speed value υ, and sends a signal that the steel plate has entered the detection area.

[0046] Step 2: During debugging, the laser point irradiated by the speed meter 8 and the pixel line of the linear camera 20 are both debugged in the gap of the roller 2, which can eliminate the influence of the rotation of the roller 2 on the detection result; the laser line of the laser 7 on the steel plate is along the forward direction of the steel plate, and the laser line and the laser point of the speed meter 8 are made in a straight line; the XY coordinate axis is established, the X coordinate axis is established through the laser line and the laser point of the speed meter 8, along the forward direction of the steel plate, and the Y coordinate axis establishes the axial direction of the roller 2, that is, the width direction of the steel plate.

[0047] Step 3: During the inspection, when the steel plate passes the velocimeter 8, the velocimeter 8 sends a signal and the linear array camera 20 starts working. One image is a straight line with a width of 1 to 2 pixels, which is responsible for detecting the width value L of the steel plate, that is, the coordinate axis Y direction;

[0048] Step 4: The laser line of the laser 7 is along the advancing direction of the steel plate, forming a longitudinal laser line. The area array camera 29 collects a photo of the laser line and calculates the ratio L1 / L of the laser line in the width direction of the steel plate, i.e., the Y direction of the coordinate axis.

[0049] Step 5: After a steel plate passes, the speed meter 8 completes the detection. Based on the measured speed value υ and the interval time t between the start and completion of the detection, the steel plate length value A at the laser line position can be calculated;

[0050] Step 6: Based on the L1 / L ratio value collected by the area array camera 29, the width value L of the steel plate detected by the line array camera 20, and the length value A detected by the speed meter 8, all length values ​​in the Y direction parallel to the X axis can be calculated according to the actual pixel values; in this way, all contour value detection of the steel plate is completed.

[0051] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
