Description

Technical Field

[0001] This utility model relates to the field of strip steel technology, specifically to a strip steel surface defect detection device. Background Technology

[0002] Plate-shaped strip steel is a type of steel product with a plate-like shape. It is a special type of strip steel. In order to ensure product quality, the surface of the strip steel will be inspected.

[0003] Inspection methods generally include manual visual inspection and optical inspection. Optical inspection involves using a camera to capture images of the steel strip surface, and then using image processing algorithms to analyze and process the images to identify various surface defects.

[0004] In existing technologies, the strip steel is usually placed flat on a workbench during inspection, and then a high-definition camera above it takes pictures. However, since it does not have the function of cleaning the surface of the strip steel, when the surface of the strip steel is covered with impurities and dust, it may affect the inspection results. Moreover, it does not have the function of flipping the strip steel, so when it is necessary to inspect the other side, it needs to be flipped manually, which is not convenient.

[0005] Therefore, this utility model designs a strip steel surface defect detection device to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a strip steel surface defect detection device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a strip steel surface defect detection device, comprising: a base, a clamping assembly on the top of the base, a bracket installed at the middle of one end of the top of the base, a detection assembly on the bracket, an elongated groove at the middle of one end of the bracket, a lead screw rotatably installed in the elongated groove, a slide block slidably installed on the outer wall of the lead screw via a thread, an air box installed at one end of the slide block, a plurality of high-pressure nozzles inclined downward on one side of the air box, and a high-pressure air pump connected to the air box on the bracket. Rotating the lead screw allows the slide block to slide, and when the air box on the slide block moves, the high-pressure nozzles move. Activating the high-pressure air pump causes the high-pressure nozzles to spray air, which blows away impurities and dust on the strip steel surface, facilitating camera detection and improving the detection effect.

[0008] Preferably, the clamping assembly includes two upright plates, which are respectively installed on the top two sides of the base. A clamping electric push rod is installed on the upright plate, and the output end of the clamping electric push rod is connected to a moving plate. A drive motor is installed on the moving plate, and the output end of the drive motor is connected to a clamping plate. A sliding groove is opened on one side of the clamping plate, and a clamping electric push rod is installed on the top of the clamping plate. The output end of the clamping electric push rod passes through the sliding groove and is fitted with a pressure plate. The strip steel is pressed tightly in the sliding groove by the pressure plate. When it is necessary to inspect the other side of the strip steel, the drive motor drives the clamping plate to rotate 180 degrees, which can automatically flip the strip steel without manual flipping, making it more convenient.

[0009] Preferably, the bottom of the movable plate is provided with several rollers, which are rotatably connected to the base. When the movable plate moves, the rollers roll on the base, which can reduce the frictional resistance of the movable plate.

[0010] Preferably, the inner wall of the chute and the bottom of the pressure plate are provided with a rubber layer, which can protect the surface of the strip steel.

[0011] Preferably, the detection component includes an electric cylinder mounted on the top of the bracket. The output end of the electric cylinder is connected to a connecting plate, and a camera is installed at the bottom center of the connecting plate. The bracket is equipped with a main unit, and the height of the camera can be adjusted by raising and lowering the connecting plate driven by the electric cylinder, which facilitates adjusting the distance between the camera and the strip.

[0012] Preferably, the bottom of the connecting plate is equipped with lights around its perimeter, which can increase brightness and improve the camera's image capture effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows the slide block to slide by rotating the lead screw. As the air box on the slide block moves, the high-pressure nozzle moves as well. Activating the high-pressure air pump causes the high-pressure nozzle to spray air, which blows away impurities and dust from the surface of the strip steel, facilitating camera inspection and improving the inspection effect. The strip steel is pressed tightly into the slide groove by the pressure plate. When it is necessary to inspect the other side of the strip steel, the drive motor drives the clamping plate to rotate 180 degrees, which can automatically flip the strip steel without manual flipping, making it more convenient.
