Description

Technical Field

[0001] This invention relates to the field of optical inspection technology, specifically to a defect detection device for special light sources and its usage method. Background Technology

[0002] Special light sources, as professional light radiation systems that differ from general lighting, are widely used in key fields such as industrial manufacturing, medical health, scientific research and national defense. Performance defects of special light sources may directly lead to medical accidents, disinfection accidents or navigation safety accidents. Therefore, before special light sources are put into use, their wavelength stability, light intensity uniformity and surface defects need to be tested.

[0003] Traditional inspection methods are divided into contact inspection and non-contact inspection. Although contact inspection can obtain three-dimensional morphology, it cannot quantify key parameters such as defect area and length, and may scratch optical surfaces. Non-contact inspection relies on line light source oblique illumination and triangulation. Although it can obtain two-dimensional defect information, it cannot meet the needs of depth inspection, and its narrow field of view cannot cover large-size light sources. Traditional inspection devices that use fixed supplementary lighting structures cannot dynamically adjust the illumination angle and intensity according to the material and shape of the light source, resulting in light spots or shadows when imaging curved or reflective surfaces, which cover up small defects.

[0004] Patent CN114812804B discloses a light source detection device and a light source detection method. The above patent realizes a simple measurement method, which can be repeatedly measured. Users are not affected by subjective factors during measurement. The measurement results are stable, accurate and have small errors, which is convenient for users to measure and record.

[0005] The aforementioned patent involves mounting the light source under test on a clamping module, which in turn is mounted on a detection light source. The light source under test emits a light beam, a portion of which is absorbed by carbon dioxide gas, while the remaining beam illuminates the detection module. The detection module receives the remaining beam, converts it into an electrical signal, and processes it. The processed electrical signal is then output by the communication module as a illuminance measurement value of the light source under test to determine its quality. This method eliminates the measurement difficulties caused by the intermittent operation of the light source and allows for optimization in terms of accuracy and adaptability for detecting special light sources for different applications.

[0006] Therefore, this application proposes a defect detection device for special light sources adapted to different models and its usage method. Summary of the Invention

[0042] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 A defect detection device for special light sources includes a mounting base 1 and a detection box 2. A fixing clip 3 is installed on the upper side of the outer wall of the mounting base 1. The detection box 2 is installed on the rear side of the outer wall of the mounting base 1. A supplementary light 4 is installed on the upper side of the inner wall of the detection box 2. A sliding groove 5 is provided at the connection between the supplementary light 4 and the detection box 2. The supplementary light 4 is connected to the sliding groove 5 through a slider 6. A rotator 7 is installed on the upper side of the outer wall of the supplementary light 4. A telescopic shaft 8 is installed on the upper side of the outer wall of the rotator 7. The supplementary light 4 is connected to the slider 6 through the rotator 7 and the telescopic shaft 8. A supplementary light motor 9 is installed on the lower side of the inner wall of the detection box 2. The slider 6, the rotator 7, and the telescopic shaft 8 are respectively connected to a switch at the output end of the supplementary light motor 9 through connecting shafts. The supplementary light motor 9 is connected to a controller 10 installed on the left side of the outer wall of the detection box 2 through a signal line.

[0043] The detection box 2 is connected to the mounting base 1 via a conveyor belt 11. A conveyor motor 12 is installed on the front side of the outer wall of the supplementary light motor 9. The conveyor belt 11 is connected to the switch at the output end of the conveyor motor 12 via a connecting shaft. A vision sensor 13 is installed on the front side of the outer wall of the detection box 2. The conveyor motor 12 and the vision sensor 13 are respectively connected to the controller 10 via signal lines.

[0044] Cameras 35 are installed in the middle of the left and right sides of the inner wall of the detection box 2. Rotator 36 is installed at the connection between the camera 35 and the detection box 2. Rotator 36 is connected to the switch at the output end of the conveyor motor 12 through a connecting shaft. Spectrometer 37 is installed on the rear side of the outer wall of the camera 35. The camera 35 and the spectrometer 37 are respectively connected to the controller 10 through signal lines.

[0045] A telescopic plate 38 is installed on the front side of the outer wall of the nozzle 24. The telescopic plate 38 is connected to the switch at the output end of the supplementary light motor 9 via a connecting shaft.

[0046] An angle sensor 39 is installed at the connection between the fill light 4 and the rotary device 7, and at the connection between the rotary device 2 36 and the camera 35. The angle sensor 39 is connected to the controller 10 through a signal line.

[0047] Furthermore, when the light source under test enters the inspection chamber 2 for surface defect detection, the controller 10 controls the supplementary light 4 to connect to an external power source to provide illumination of different intensities, depending on the model of the light source under test. Simultaneously, during the inspection process, the information collected by the illumination at different positions and angles varies. For example, when the top of the light source under test is illuminated, vertical light causes raised defects to cast shadows, while recessed areas reflect weak light, enabling the detection of scratches, pits, and foreign matter attachments on metal or highly reflective surfaces. Illumination at an incident angle of 15°–45° can detect minor scratches, oil stains, and surface unevenness. The controller 10 adjusts the position of the supplementary light 4 according to the model of the light source under test, and the controller 10 also controls the supplementary light motor. The switch at output 9 connects to slider 6. The supplementary light motor 9 drives slider 6 to move within the slide groove 5, adjusting the horizontal position of the supplementary light 4. Then, the supplementary light motor 9 connects to the telescopic shaft 8 to adjust the height of the supplementary light 4. Finally, the supplementary light motor 9 connects to the rotator 7 to adjust the angle of the supplementary light 4, positioning it at different locations to illuminate the surface of the light source under test. After the position adjustment of the supplementary light 4 is complete, the camera 35 collects information about the surface of the light source under test and transmits it to the controller 10. During this process, the controller 10 receives the angle adjustment parameters of the supplementary light 4 collected by the angle sensor 39 at the supplementary light 4 and controls the output of the conveyor motor 12. The switch at the end is connected to the second rotator 36, which adjusts the angle of the camera 35. Angle sensors 39 at both the supplementary light 4 and the camera 35 collect the angle adjustment parameters. Combined with the orientation change of the supplementary light 4, the camera 35 can accurately capture the required surface information of the light source under test. After completing the surface defect detection of the light source under test, the controller 10 controls the supplementary light motor 9 to reset the supplementary light 4 and disconnect it from the external power supply, restoring darkness to the inside of the detection box 2. The controller 10 then controls the switch at the output end of the supplementary light motor 9 to connect to the telescopic plate 38. Driven by the supplementary light motor 9, the telescopic plate 38 extends. The nozzle 24 inside the test chamber 2 is separated from the light source to be tested. The operator connects the light source to a stable external power supply to avoid distortion of the test results caused by fluctuations in the external power supply. The light source to be tested is then irradiated onto the telescopic plate 38. At this time, the spectrum of the light source to be tested is collected by the spectrometer 37 and transmitted to the controller 10. The distribution of light spots on the telescopic plate 38 is collected by the camera 35 and transmitted to the controller 10. The controller 10 analyzes the information collected by the camera 35 and the spectrometer 37 to obtain the wavelength stability and illumination uniformity of the light source to be tested. At the same time, in order to more intuitively understand the illumination performance of the light source to be tested, the operator can add patterns on the telescopic plate 38, thereby improving the convenience and efficiency of the test.

[0048] Example 2: Please refer to Figure 1 and Figure 4A defect detection device for a special light source, wherein the detection box 2 is connected to the mounting base 1 via a conveyor belt 11, a conveyor motor 12 is installed on the front side of the outer wall of the supplementary light motor 9, the conveyor belt 11 is connected to the switch at the output end of the conveyor motor 12 via a connecting shaft, a vision sensor 13 is installed on the front side of the outer wall of the detection box 2, and the conveyor motor 12 and the vision sensor 13 are respectively connected to the controller 10 via signal lines;

[0049] An adjustment assembly is installed at the connection between the mounting base 1 and the fixing clamp 3. The adjustment assembly consists of a spring 14, an adjustment column 15, a movable disk 16, and a movable column 17. A movable column 17 is installed on the lower outer wall of the fixing clamp 3, and an adjustment column 15 is installed on the lower outer wall of the movable column 17. A spring 14 is installed in the middle of the inner wall of the adjustment column 15, and a movable disk 16 is installed on the upper outer wall of the spring 14. A second slide groove 18 is installed at the connection between the mounting base 1 and the fixing clamp 3 and the adjustment column 15. A second slider 19 is installed in the middle of the inner wall of the second slide groove 18. The movable disk 16 and the second slider 19 are respectively connected to the switch at the output end of the conveying motor 12 through a connecting shaft. A vibration sensor 20 is installed on the lower inner wall of the mounting base 1. The vibration sensor 20 is connected to the controller 10 and the adjustment assembly through a signal line.

[0050] Furthermore, the operator places the special light source to be tested in front of the mounting base 1. Before the light source is placed on the mounting base 1, the vision sensor 13 can collect information about the light source, obtaining its size and model. When the controller 10 controls the switch at the output end of the conveyor motor 12 to connect to the slider 19 based on the size information of the light source collected by the vision sensor 13, the fixing clamp 3 moves under the guidance of the slide groove 18 driven by the slider 19, changing the distance between the fixing clamps 3. Then, the operator places the light source to be tested on the fixing clamp 3. During this process, after the vision sensor 13 detects the operator's movement, it controls the conveyor motor 12 to drive the slider 19 to move the fixing clamp 3 to fix the light source to be tested. The controller 10 controls the switch at the output end of the conveyor motor 12 to connect to the conveyor belt 11. The conveyor belt 11, driven by the conveyor motor 12, transports the mounting base 1 into the detection box 2. In order to avoid the light source to be tested from deviating due to shaking or affecting the detection results, the adjustment component located in the mounting base 1 is used to eliminate environmental shaking. When environmental shaking is present, the vibration is transmitted from the mounting base 1. The spring 14 inside the adjusting column 15 is compressed or stretched, and the deformation of the spring 14 drives the moving disk 16. The moving disk 16 engages with the groove provided in the adjusting column 15, thereby avoiding lateral displacement and amplifying vibration. The movement of the moving disk 16 is transmitted to the moving column 17, and the moving column 17 deflects at a small angle to further absorb vibration, thereby reducing the influence of environmental shaking on the light source under test. During the test, in order to verify the stability of the light source under test in a shaking environment, when the vibration sensor 20 detects that the test box 2 and the conveyor belt 11 and other structures are not vibrating, The controller 10 controls the switch at the output of the conveyor motor 12 to connect to the moving disk 16. The moving disk 16 moves down under the drive of the conveyor motor 12, which further compresses the spring 14 and causes the moving column 17 to move down, thereby causing the fixed clamp 3 to shake. The moving disk 16 moves down when there is an external force and resets under the action of the spring 14 when there is no external force. The controller 10 controls the magnitude and time interval of the power delivered to the moving disk 16 by the conveyor motor 12 to make the fixed clamp 3 shake at different frequencies and periods, which can test the stability and environmental adaptability of the light source under test.

[0051] Example 3: Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 A defect detection device for a special light source, wherein the detection box 2 is connected to the mounting base 1 via a conveyor belt 11, a conveyor motor 12 is installed on the front side of the outer wall of the supplementary light motor 9, the conveyor belt 11 is connected to the switch at the output end of the conveyor motor 12 via a connecting shaft, a vision sensor 13 is installed on the front side of the outer wall of the detection box 2, and the conveyor motor 12 and the vision sensor 13 are respectively connected to the controller 10 via signal lines;

[0052] A temperature sensor 21 is installed in the middle of the inner wall of the detection chamber 2. A humidity sensor 22 is installed on the upper side of the outer wall of the temperature sensor 21. A water tank 23 is installed on the rear side of the outer wall of the detection chamber 2. A nozzle 24 is installed on the rear side of the inner wall of the detection chamber 2. The nozzle 24 is connected to a pressure pump 25 installed on the upper side of the outer wall of the water tank 23 through a connecting pipe. A fan 26 is installed on the front side of the outer wall of the water tank 23. A heating wire 27 is installed on the front side of the outer wall of the fan 26. An air guide pipe 28 is installed on the front side of the outer wall of the heating wire 27. The air guide pipe 28 is connected to an air valve 29 in the middle of the inner wall of the detection chamber 2. The pressure pump 25 and the fan 26 are respectively connected to a switch at the output end of the pressure motor 30 installed on the front side of the outer wall of the pressure pump 25 through a connecting shaft. The temperature sensor 21, the humidity sensor 22 and the pressure motor 30 are respectively connected to the controller 10 through signal lines.

[0053] A telescopic plate 38 is installed on the front side of the outer wall of the nozzle 24. The telescopic plate 38 is connected to the switch at the output end of the supplementary light motor 9 via a connecting shaft.

[0054] Furthermore, after the operator fixes the light source to be tested onto the fixing clamp 3, the operator inputs the model of the light source to be tested into the controller 10. The controller 10 obtains the test environment of the light source to be tested based on the information collected by the vision sensor 13 and the model input by the operator. The temperature and humidity inside the test chamber 2 are detected by the temperature sensor 21 and the humidity sensor 22 and compared with the temperature and humidity of the test environment of the light source to be tested. If a temperature and humidity mismatch occurs, the controller 10 connects the pressure motor 30 to the pressure motor via the switch at the output end. Pump 25, driven by pressurizing motor 30, pressurizes water in water tank 23 and sprays it into test chamber 2 through nozzle 24. Then, controller 10 controls the pressurizing motor 30 to connect to fan 26, causing fan 26 to rotate and opening air valve 29. Water mist entering test chamber 2 through air pipe 28 is dispersed, causing the humidity inside test chamber 2 to rise evenly. If the humidity inside test chamber 2 is too high, controller 10 only opens air valve 29 to connect air pipe 28 to test chamber 2, and the pressurizing motor 30 drives fan 26 to adjust the humidity inside test chamber 2. The airflow inside reduces the humidity and temperature inside the test chamber 2. When the temperature inside the test chamber 2 is low, the controller 10 controls the pressurizing motor 30 to drive the fan 26 to rotate, and also controls the heating wire 27 to connect to an external power source to heat up. This turns the cold air entering the test chamber 2 from the air duct 28 through the air valve 29 into hot air, raising the temperature inside the test chamber 2. This ensures that the temperature and humidity inside the test chamber 2 do not affect the accuracy of the test results when the light source under test enters the test chamber 2 for testing. In addition, to verify the stability of the light source under test in different environments, the controller 10 can detect and adjust the temperature and humidity in the test chamber 2 based on the environmental information that the light source under test may use, using the temperature sensor 21 and humidity sensor 22. For example, the controller 10 can spray water pressurized by the pressurizing pump 25 through the nozzle 24 to increase the humidity inside the test chamber 2 and test the operation of the light source under test in a high-humidity environment. The controller 10 can also blow hot air heated by the heating wire 27 into the test chamber 2 by opening the air valve 29 to test the operation of the light source under test in a high-temperature environment.

The base 31 is installed on the upper side of the outer wall of the moving column 17. The buffer block 32 is installed on the right side of the outer wall of the base 31. The pressure sensor 33 is embedded in the right side of the outer wall of the buffer block 32. A sliding groove 34 is provided at the connection between the buffer block 32 and the base 31. The buffer block 32 is connected to the switch at the output end of the conveying motor 12 through a connecting shaft. The pressure sensor 33 is connected to the controller 10 through a signal line.

[0057] Furthermore, after the operator places the light source to be tested in the middle of the fixing clamp 3 for fixation, the buffer block 32 contacts the light source to be tested. The pressure sensor 33 detects the clamping force of the fixing clamp 3 on the light source to be tested. This prevents the distance between the bases 31 from being too large, resulting in insufficient clamping force and causing the light source to loosen during the testing process, and prevents the distance between the bases 31 from being too small, resulting in excessive clamping force and causing defects on the surface of the light source to be tested due to external force. When the clamping force is too small or too large, the conveyor motor 12 drives the slider 19 to move in the slide groove 18 to adjust the position of the base 31. During the adjustment of the position of the supplementary light 4 by the controller 10, in order to ensure accurate detection of surface defects of the light source to be tested, the controller 10 controls the switch at the output end of the conveyor motor 12 to connect to the buffer block 32, so that... The position of the buffer block 32 changes, thereby adjusting the height or offset angle of the light source under test. For example, by controlling the buffer block 32 on one side of the light source under test to move on the slide groove 34, the light source under test can be deflected, thereby collecting information from the side of the light source under test. At the same time, it can avoid the situation where adjusting the position of the supplementary lamp 4 alone is not enough to obtain accurate information. If there are defects at the edge of the light source under test, light scattering can easily lead to blurred imaging. When the adjustment component actively vibrates the light source under test, it can drive the light source under test to move along the vertical slide groove 34 through the buffer block 32, thereby adjusting the height of the light source under test. This causes the light source under test to move up and down during vibration, making the vibration provided by the adjustment component more likely to reveal hidden cracks, thereby improving the detection accuracy of the light source under test and avoiding the failure to detect hidden cracks.

[0058] Example 5: Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 A defect detection device for a special light source, wherein an adjustment component is installed at the connection between the mounting base 1 and the fixing clamp 3, the adjustment component consists of a spring 14, an adjustment column 15, a moving disk 16 and a moving column 17, the moving column 17 is installed on the lower side of the outer wall of the fixing clamp 3, the adjustment column 15 is installed on the lower side of the outer wall of the moving column 17, the spring 14 is installed in the middle of the inner wall of the adjustment column 15, the moving disk 16 is installed on the upper side of the outer wall of the spring 14, a second slide groove 18 is installed at the connection between the mounting base 1 and the fixing clamp 3 and the adjustment column 15, a second slider 19 is installed in the middle of the inner wall of the second slide groove 18, the moving disk 16 and the second slider 19 are respectively connected to the switch at the output end of the conveying motor 12 through a connecting shaft, and a vibration sensor 20 is installed on the lower side of the inner wall of the mounting base 1, the vibration sensor 20 is connected to the controller 10 and the adjustment component through a signal line respectively;

[0059] A temperature sensor 21 is installed in the middle of the inner wall of the detection chamber 2. A humidity sensor 22 is installed on the upper side of the outer wall of the temperature sensor 21. A water tank 23 is installed on the rear side of the outer wall of the detection chamber 2. A nozzle 24 is installed on the rear side of the inner wall of the detection chamber 2. The nozzle 24 is connected to a pressure pump 25 installed on the upper side of the outer wall of the water tank 23 through a connecting pipe. A fan 26 is installed on the front side of the outer wall of the water tank 23. A heating wire 27 is installed on the front side of the outer wall of the fan 26. An air guide pipe 28 is installed on the front side of the outer wall of the heating wire 27. The air guide pipe 28 is connected to an air valve 29 in the middle of the inner wall of the detection chamber 2. The pressure pump 25 and the fan 26 are respectively connected to a switch at the output end of the pressure motor 30 installed on the front side of the outer wall of the pressure pump 25 through a connecting shaft. The temperature sensor 21, the humidity sensor 22 and the pressure motor 30 are respectively connected to the controller 10 through signal lines.

[0060] Furthermore, after the light source under test enters the test chamber 2, it is connected to an external power supply to put it into operation. The controller 10 controls the operation according to the working environment of the light source under test. For example, if the laser operating temperature needs to be maintained between 20 and 30°C and the humidity needs to be maintained between 40% and 60%, the pressurizing motor 30 drives the pressurizing pump 25 to spray water from the water tank 23 into the test chamber 2 through the nozzle 24. The humidity sensor 22 detects the humidity in the test chamber 2 to ensure that the humidity in the test chamber 2 is between 40% and 60%. The pressurizing motor 30 drives the fan 26 to rotate and connects the heating wire 27 and the external power supply to blow hot air out through the air duct 28 from the air valve 29. The light source is placed in the testing chamber 2, and the temperature in the testing chamber 2 is detected by the temperature sensor 21 to ensure that the temperature in the testing chamber 2 is between 20 and 30°C. After running for a period of time in the actual working environment of the laser, the controller 10 controls the conveyor motor 12 to drive the moving disk 16 to actively apply vibration through the adjustment component. By controlling the movement frequency of the moving disk 16, the vibration frequency is adjusted so that the light source under test runs in the set temperature, humidity and vibration frequency environment. Before and after the two runs, the light source under test is inspected for defects. If the defects do not affect the operation of the special light source, it does not need to be judged as a waste product. If the defects affect the operation of the special light source, it is judged as a waste product, thus completing the screening of special light sources.

[0061] Working principle: After the vision sensor 13 detects that the operator has placed the light source to be tested in the middle of the fixing clamp 3, the controller 10 controls the conveyor motor 12 to drive the slider 19 to move in the slide groove 18, so that the fixing clamp 3 fixes the light source to be tested. Then, the conveyor motor 12 is switched to connect, so that the conveyor belt 11 is driven by the conveyor motor 12 to transport the light source to be tested into the detection box 2 for detection. In this process, in order to avoid the light source to be tested from loosening or additional defects due to pressure deviation of the fixing clamp 3, the pressure sensor 33 detects the pressure applied to the buffer block 32. At the same time, in order to avoid the light source to be tested from shifting and image acquisition from mechanical vibration and environmental vibration, the spring 14 in the adjusting column 15 is compressed or stretched. The deformation of the spring 14 drives the moving disk 16. The moving disk 16 engages with the groove set in the adjusting column 15, thereby avoiding lateral shift and amplification of vibration. The movement of the moving disk 16 is transmitted to the moving column 17. The moving column 17 swings at a small angle to further absorb vibration, thereby reducing the impact of environmental shaking on the light source to be tested.

[0062] After the light source to be tested is moved into the test chamber 2, the controller 10 controls the temperature sensor 21 and humidity sensor 22 to detect the temperature and humidity inside the test chamber 2 according to the model of the light source to be tested. The controller 10 controls the pressurizing motor 30 to drive the pressurizing pump 25 to pressurize the water in the water tank 23 and spray it out from the nozzle 24 to humidify the inside of the test chamber 2. The controller 10 controls the pressurizing motor 30 to drive the fan 26, selects to connect the heating wire 27 and the external power supply, and delivers cold or hot air from the air duct 28 to the air valve 29 to adjust the temperature and humidity inside the test chamber 2, thereby ensuring that the temperature and humidity inside the test chamber 2 will not affect the operation of the supplementary light 4, camera 35 and spectrometer 37.

[0063] The controller 10 controls the supplementary light motor 9 to connect the slider 6, the telescopic shaft 8 and the rotator 7 in sequence to adjust the position and angle of the supplementary light 4. The supplementary light 4 provides the camera 35 with light from different directions and intensities, enabling the camera 35 to complete the detection of surface defects of the light source under test. The controller 10 controls the conveyor motor 12 to drive the buffer block 32 on one side of the light source under test to raise or lower one side of the light source under test, so that the camera 35 can collect images of the light source under test from different angles to avoid missed detections. Then, the supplementary light 4 is disconnected from the external power supply, and the telescopic plate 38 is extended by the supplementary light motor 9 to connect the external power supply and the light source under test. The camera 35 collects the light spot on the telescopic plate 38 to detect the uniformity of illumination, and the spectrometer 37 collects the wavelength of the light source under test to detect the wavelength stability.

[0064] After the initial test is completed, the controller 10 controls the conveyor motor 12 to connect the moving disk 16 and the buffer block 32. Driven by the conveyor motor 12, the moving disk 16 cyclically presses down the spring 14, causing the moving column 17 to drive the base 31 to shake continuously. The buffer block 32 moves along the slide groove 34, causing the light source under test to shift to one side or change its height. The temperature and humidity in the test chamber 2 can also be changed by the pressure pump 25 and the fan 26 to test the stability of the light source under test in a complex environment.
