Description

Technical Field

[0001] This utility model relates to the field of metal product testing technology, specifically to a metal product surface defect testing device. Background Technology

[0002] In modern industrial production systems, the surface quality of metal products directly determines their performance, lifespan, and application scenarios. Taking automobile manufacturing as an example, if metal parts such as body panels and chassis structural components have defects such as scratches, dents, and oxide scale, it will not only affect the aesthetics but may also cause safety hazards such as stress concentration and accelerated corrosion during long-term use. Traditional methods for detecting surface defects in metal products rely on manual visual inspection. Inspectors need to observe the surface of each workpiece one by one under strong light sources, which is labor-intensive and inefficient.

[0003] With the widespread adoption of automated production lines, existing industrial inspection equipment has incorporated industrial cameras for visual inspection. These cameras capture images of metal product surfaces from fixed positions and then perform algorithmic analysis. However, these devices face two major problems in practical applications: First, lighting interference leads to insufficient inspection accuracy. Metal product surfaces have high reflectivity, and fluctuations in the intensity or angle of ambient light (such as workshop lighting and window incident light) can cause glare, shadows, or abnormal contrast in the captured images. Second, the amount of manual intervention is significant, limiting the degree of automation. Existing equipment typically requires manual placement of metal products at the inspection station, followed by manual transfer to the next process after inspection, making seamless integration with the continuous transport system of the production line impossible. Utility Model Content

[0004] The purpose of this invention is to provide a metal product surface defect detection device, which aims to improve the problem that existing metal product surface detection devices are easily affected by external light.

[0005] This utility model is implemented as follows: A surface defect detection device for metal products includes a base, a processing shell horizontally mounted on the upper surface of the base, the processing shell being fixedly connected to the base, a horizontal transmission component installed in the processing shell, and a drive motor for driving the horizontal transmission component to rotate fixedly mounted on the base. A detection platform is also vertically mounted on the upper surface of the base. The upper surfaces of the horizontal transmission component and the detection platform are flush with the upper surface of the processing shell. A light shield is also installed between the detection platform and the processing shell, and a telescopic hydraulic cylinder for driving the light shield to rise and fall is fixedly mounted on the base. A transfer component for transferring metal products between the horizontal transmission component and the detection platform is also installed on the processing shell, and a rotary hydraulic cylinder for driving the transfer component to rotate is installed on the lower surface of the processing shell. A detection camera that cooperates with the detection platform is fixedly mounted on the upper surface of the processing shell.

[0006] Preferably, the equipment base includes a base plate and a back plate for mounting the processing shell. The back plate is vertically mounted on the rear end face of the base plate and is fixedly connected to the base plate.

The drive roller and the driven roller are rotatably mounted on both sides of the processing housing, and the two ends of the conveyor belt are sleeved on the drive roller and the driven roller.

[0008] Preferably, the testing table includes a support rod and a platform, the support rod is vertically fixed to the upper end face of the base plate, and the platform is fixedly installed on the head of the support rod.

[0009] Preferably, the transfer assembly includes a rotating base, a positioning frame, and a movable frame. The positioning frame is fixedly installed on the head of the rotating base, the movable frame is slidably installed on the positioning frame, and an electric cylinder for driving the movable frame to move is installed on the positioning frame.

[0011] Preferably, a limiting plate is also installed at the outer end of the rotating rod portion, and the limiting plate is fixedly connected to the rotating rod portion.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This application achieves automatic transmission, transfer, and inspection of metal products through the coordinated work of horizontal transmission components, transfer components, etc., reducing manual intervention and improving inspection efficiency. The setting of the light shield avoids interference from external light, which can effectively reduce image shooting deviation caused by changes in external light compared with the traditional method of direct shooting inspection. It solves the problem that existing industrial cameras are greatly affected by lighting conditions and surface reflection when capturing images of metal surfaces, so that the inspection camera can accurately capture images of the surface of metal products, thereby improving the accuracy of inspection.
