[0002] Intelligent zinc spraying robot is an automated equipment used for anti-corrosion treatment of metal surfaces. It achieves precise zinc coating through intelligent control system and is widely used in industrial fields such as pipelines and steel structures. It mainly consists of robot, intelligent controller, spraying execution mechanism and auxiliary detection device. The detection device can detect defects in the spraying process in time, so that remedial measures can be taken quickly to improve the spraying quality.

[0022] Example 1

[0023] like Figure 1-5 As shown, this is the first embodiment of the present invention. This embodiment provides a visual inspection device for an intelligent zinc spraying equipment, including a base 100, a six-axis robotic arm 200, a visual inspection component 300 including a PLC controller 310, a detection unit 320 for visual inspection, a protective cover 321 fixed to the execution end of the six-axis robotic arm 200, a CMOS camera 322 mounted on the bottom of the protective cover 321, and a polarizing lens 323 fixed to the shooting end of the CMOS camera 322, and a supplementary lighting component 400 including an LED white light 410 and an infrared supplementary light 420 for supplementary lighting. The infrared fill light 420 is equipped with a Fresnel lens 430 for focusing the light, and the Fresnel lens 430 is installed at the illumination end of the infrared fill light 420. The display assembly 500 includes a display screen 510 for displaying the shooting data of the CMOS camera 322, and a mounting bracket 520 for fixing the display screen 510. There are two sets of infrared fill lights 420, which are respectively installed on both sides of the protective cover 321. Each set of infrared fill lights 420 is equipped with a Fresnel lens 430. The number of CMOS cameras 322 is set to a certain number, and each CMOS camera 322 is equipped with a polarizing lens 323.

[0024] like Figure 1-5As shown, the LED white light 410 is ring-shaped and fixed to the bottom of the protective cover 321, providing uniform white light illumination, which helps to capture the overall color and basic features of objects. The infrared supplementary light 420 illuminates from both sides of the protective cover 321 at a 45° angle. This multi-angle illumination method can reduce reflections caused by a single-direction light source. At the same time, the Fresnel lens 430 is installed at the irradiation end of the infrared supplementary light 420, which can focus the infrared light, enhance the light intensity of specific areas, further optimize the illumination effect, and thus reduce the interference of reflections on imaging. Each CMOS camera 322 is equipped with a polarizing lens 323. The polarizing lens 323 can selectively filter light, allowing only light vibrating in a specific direction to pass through. The reflections on the zinc sprayed layer surface are usually partially polarized light. By adjusting the angle of the polarizing lens 323, reflections can be effectively reduced or eliminated, reducing imaging noise. To improve image clarity, when photographing zinc-sprayed layers with metallic reflective properties, the polarized lens 323 can block the light from the reflective parts, allowing the camera to capture a more realistic and clear image. The CMOS cameras 322 are arranged in an array, allowing for image capture of the zinc-sprayed layer from different angles, obtaining more comprehensive image information. Images from different angles can complement each other, reducing the loss of local information caused by reflection, thereby improving the accuracy and reliability of visual inspection. Simultaneously, image data from multiple cameras can be comprehensively processed and analyzed in the PLC controller 310, further enhancing the inspection effect. Through the combination of multi-source lighting, polarized lens application, multi-camera collaborative detection, and intelligent control and data display, the imaging problem caused by metallic reflection on the zinc-sprayed layer surface can be effectively solved, improving image clarity and visual inspection performance.

[0028] The display screen 510 is mounted on the surface of the bracket 520, and one end of the bracket 520 is fixedly connected to the base 100.

[0029] The six-axis robotic arm 200 is fixed to the top of the base 100, and the PLC controller 310 is fixed to one side of the base 100.

[0030] The infrared fill light 420 is installed at a 45° angle, and the LED white light 410 is fixed to the bottom of the protective cover 321 and is in a ring shape.

[0031] The output of the CMOS camera 322 is connected to the input of the PLC controller 310. The output of the PLC controller 310 is connected to the input of the six-axis robotic arm 200, the infrared fill light 420, and the LED white light 410, respectively.

[0032] like Figure 1-5 As shown, the PLC controller 310 can adjust the position and posture of the six-axis robotic arm 200, as well as the brightness and on / off status of the light source, based on the image data captured by the camera, to adapt to different detection scenarios and reflection conditions. The display screen 510 can display the data captured by the CMOS camera 322 in real time, allowing operators to intuitively observe the detection results, promptly identify problems, and make adjustments. The bracket 324 and mounting plate 325 in the detection unit 320 firmly fix the CMOS camera 322 inside the protective cover 321, ensuring that the camera will not shake during operation and ensuring the stability of the image capture. The display screen 510 is mounted on the base 100 via the mounting bracket 520, making it convenient for operators to view the captured data and improving the ease of operation. The six-axis robotic arm 200 is fixed to the top of the base 100 and can move and adjust its posture flexibly within a large range, accurately delivering the vision inspection component 300 to the required inspection position to adapt to the inspection needs of workpieces of different shapes and sizes.

[0033] In use, the output of the CMOS camera 322 is connected to the input of the PLC controller 310, enabling the image data captured by the CMOS camera 322 to be transmitted to the PLC controller 310. The output of the PLC controller 310 is connected to the input of the six-axis robotic arm 200, the infrared fill light 420, and the LED white light 410, respectively, allowing the PLC controller 310 to control the operation of these devices and provide a hardware control basis for subsequent inspection work. Under the control of the PLC controller 310, the six-axis robotic arm 200 can flexibly adjust the position and angle of the vision inspection component 300 to move the CMOS camera 322 to the zinc spraying area to be inspected, ensuring accurate imaging of the inspection target. The CMOS camera 322 is installed at the bottom of the protective cover 321, and each CMOS camera 322 is equipped with a polarizing lens 323. The polarizing lens 323 can reduce the interference of reflected light and improve the clarity and quality of the image. After the six-axis robotic arm 200 moves the CMOS camera 322 to the appropriate position, the CMOS camera 322 begins to acquire images of the zinc spraying area.

[0034] The LED white light 410 is fixed to the bottom of the protective cover 321 in a ring shape, providing uniform white light illumination to light the detection area. Simultaneously, two sets of infrared supplementary lights 420 are installed on both sides of the protective cover 321. Each set of infrared supplementary lights 420 is equipped with a Fresnel lens 430, which focuses the infrared light, enhancing its intensity and range. The infrared supplementary lights 420 are installed at a 45° angle, providing auxiliary lighting from the side to further reduce the influence of shadows and improve image acquisition. The CMOS camera 322 transmits the acquired image data to the PLC controller 310. The PLC controller 310 processes and analyzes this data to determine whether the zinc spraying thickness and uniformity meet the requirements. The processed results are transmitted to the display component 500, which displays the data captured by the CMOS camera 322 and the processing results, allowing operators to intuitively understand the quality of the zinc spraying.
