Description

Technical Field

[0001] This invention relates to the field of solar simulator inspection, specifically to a surface defect detection device for a solar simulator. Background Technology

[0002] A solar simulator is a sophisticated device that uses artificial light sources to simulate the solar spectrum and irradiance characteristics. Its core objective is to reproduce the real sunlight conditions in a laboratory, providing a stable, controllable, and repeatable lighting environment for various research, testing, and production processes that require sunlight.

[0003] After production, solar simulators may develop cracks, damage, stains, or other defects on their appearance. These defects can lead to abnormal light paths, affecting the accuracy of light intensity and spectral distribution. Surface stains can reduce light transmittance, while cracks can cause stress concentration, impacting structural stability. Furthermore, surface defects such as uneven edges and damaged junction boxes can pose a risk of electrical leakage. Therefore, surface defect detection is crucial. Existing detection devices typically use multiple laser probes to scan the surface of the solar simulator and analyze for defects. However, when fixing the solar simulator, two clamps are needed to hold it in place. The laser probes cannot scan the contact surface between the clamps and the solar simulator surface, requiring manual replacement of the clamping surfaces, which is cumbersome and necessitates realigning the solar simulator with the laser probes, further reducing detection efficiency.

A vertical groove for limiting the sliding movement of the pulleys is opened on the outer side of the mounting frame. A first gear is fixedly installed on the end of the mounting rod away from the limiting plate. A first rack is fixedly installed on the inner side of the mounting frame. An inclined groove connected to the vertical groove is opened on the outer side of the mounting frame.

[0007] Preferably, the receiving mechanism further includes two slide rods symmetrically fixedly installed at the bottom of the placement plate. A sleeve is slidably installed on the outer side of the slide rod, and the bottom of the sleeve contacts the top of the device base. Two symmetrically distributed pull rods are fixedly installed between the side of the push plate away from the placement plate and the bottom of the slide frame. A sleeve plate is fixedly installed between the two sleeves. A circular hole is opened on the surface of the sleeve plate for the opposite screw to pass through. Two symmetrically distributed connecting pipes are fixedly installed between the sleeve plate and the moving block. The connecting pipes are slidably installed on the outer side of the optical axis.

[0008] Preferably, the angle adjustment mechanism further includes two positioning rods symmetrically fixedly installed on the outside of the microcontroller. The positioning rods are rotatably installed on the inside of the U-shaped frame. The U-shaped frame is fixedly installed on the top inner wall of the gantry frame. A second gear is fixedly installed at the end of the positioning rod away from the microcontroller. Two third gears are rotatably installed on the outside of the U-shaped frame, each meshing with one of the two second gears. The outer diameter of the third gear is smaller than that of the second gear, and the length of the third gear is greater than that of the second gear. Two symmetrically distributed brackets are fixedly installed on the top of the mounting frame. A second rack is fixedly installed at the top of each bracket, and the two second racks mesh with the two third gears respectively.

[0009] Preferably, the limiting plate has a triangular plate structure, and a rubber pad is provided at the end of the limiting plate.

The U-shaped rod slides through the limiting plate, and two symmetrically distributed springs are fixedly installed between the rubber pad and the limiting plate.

[0010] Preferably, the rubber pad has multiple anti-slip grooves distributed at equal intervals on the side away from the U-shaped rod, and the three rubber pads are centrally symmetrically distributed.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention, through a detection mechanism, enables two limiting plates to clamp and position the outside of the simulator body, and then moves and rotates the two limiting plates upward. The limiting plates can then flip the simulator body and move away from the outside of the simulator body, allowing the two cameras to capture a full view of the outside of the simulator body, thereby improving defect detection efficiency.

[0016] 2. The present invention, through the receiving mechanism, enables the push plate and the placement plate to move upward synchronously when the limiting plate moves upward. While the placement plate moves upward, it maintains the distance between itself and the simulator body, so that the placement plate can catch the simulator body in time. When the horizontal position of the limiting plate is adjusted, the placement plate can be moved accordingly, so that the distance between the two placement plates can be adjusted according to the size of the simulator body, thereby improving the safety of the simulator body detection.

[0017] 3. The present invention uses an angle adjustment mechanism to synchronously adjust the angles of the two cameras during the movement of the mounting frame. When the size of the simulator body is small, the two cameras can swing downwards accordingly, and vice versa. This optimizes the shooting range for simulator bodies of different sizes, thereby improving the accuracy of defect detection. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-8 The diagram illustrates a surface defect detection device for a solar simulator, comprising a base 1 and a simulator body 2 mounted on top of the base 1. A gantry 3 is fixedly mounted on the top of the base 1, and two symmetrically distributed microcontrollers 4 are mounted on the bottom of the gantry 3. Cameras 5 are mounted on the outside of the microcontrollers 4, and a display screen 6 is mounted on the top of the gantry 3. The microcontrollers 4 are connected to the display screen 6 via cables, allowing the cameras 5 to capture images of the outside of the simulator body 2. The microcontrollers 4 collect and process the images and transmit them to the display screen 6 via cables for clear observation by the inspectors. Two symmetrically distributed placement plates 7 are mounted on the top of the base 1 for placing the simulator body 2 to be inspected. The device also includes a detection mechanism for comprehensive inspection of the simulator body 2, which is mounted on the top of the base 1.

[0022] The detection mechanism includes two symmetrically arranged limiting plates 8 above the device base 1. The limiting plates 8 can clamp the outer side of the simulator body 2 and rotate it, enabling the camera 5 to capture a full view of the simulator body 2. The detection mechanism also includes two symmetrically fixed support plates 11 on the top of the device base 1. A counter-rotating screw 12 is rotatably installed between the two support plates 11. A drive motor is fixedly installed on the outer side of the device base 1. The output end of the drive motor is fixedly connected to one end of the counter-rotating screw 12, enabling the drive motor to drive the counter-rotating screw 12 to rotate. Two moving blocks 13 are threaded onto the two threads on the outer side of the counter-rotating screw 12. Two optical axes for limiting and sliding the moving blocks 13 are installed between the two support plates 11, so that when the counter-rotating screw 12 rotates, it can drive the two... The movable blocks 13 move closer to or further away from each other along the outer side of the optical axis. A mounting frame 14 is fixedly installed on the top of each movable block 13. An electric telescopic rod 15 is fixedly installed on the inner side of the mounting frame 14. A slide 16 is fixedly installed on the top of the electric telescopic rod 15. A sleeve block 17 is slidably installed on the outer side of the slide block 16. Mounting rods 18 are rotatably installed on the inner side of the sleeve block 17. One end of each mounting rod 18 is fixedly connected to the side of each limiting plate 8 away from the simulator body 2. Two symmetrically distributed pulleys 19 are rotatably installed on the outer side of the sleeve block 17. A vertical groove is provided on the outer side of the mounting frame 14 for the pulleys 19 to slide and be limited, allowing the movable blocks 13 to move the slide 16 on the electric telescopic rod 15 via the mounting frame 14. The vertical groove on the mounting frame 14 facilitates sliding... With the wheel 19 in a limiting position, the mounting rod 18 on the inner side of the sleeve block 17 can drive the limiting plate 8 to contact the outer side of the simulator body 2, so that the two limiting plates 8 clamp and position the simulator body 2. The end of the mounting rod 18 away from the limiting plate 8 is fixedly mounted with a first gear 20, and the inner side of the mounting frame 14 is fixedly mounted with a first rack 21. The outer side of the mounting frame 14 is provided with an inclined groove connected to the vertical groove, so that when the electric telescopic rod 15 pushes the slide 16 to move upward, the slide 16 can drive the pulley 19 on the sleeve block 17 to move upward along the vertical groove on the mounting frame 14, so that the limiting plate 8 lifts the simulator body 2 upward, and when the first gear 20 on the mounting rod 18 contacts the first rack 21, the first rack 21 drives the mounting rod through the first gear 20. When the mounting rod 18 rotates, it can cause the simulator body 2 to flip via the limiting plate 8, allowing the two cameras 5 to capture images of the simulator body 2 in the flipped state. When the pulley 19 moves onto the inclined groove, it moves along the inclined groove and pulls the sleeve block 17 to move horizontally along the outside of the slide 16. The sleeve block 17 can then move the limiting plate 8 on the mounting rod 18 away from the simulator body 2 and onto the placement plate 7, facilitating the cameras 5 to capture images of the side of the simulator body 2, thus achieving a full-view image of the simulator body 2. The limiting plate 8 has a triangular plate structure, and a rubber pad 31 is provided at the end of the limiting plate 8. A U-shaped rod 32 is fixedly installed on the side of the rubber pad 31 near the limiting plate 8, and the U-shaped rod 32 slides through the limiting plate 8.Two symmetrically distributed springs 33 are fixedly installed between the rubber pad 31 and the limiting plate 8, allowing the limiting plate 8 to clamp the outer side of the simulator body 2 via the rubber pad 31. The elasticity of the springs 33 provides elastic clamping of the simulator body 2, improving the firmness of the clamping. Multiple equidistant anti-slip grooves are provided on the side of the rubber pad 31 away from the U-shaped rod 32, and the three rubber pads 31 are centrally symmetrically distributed, with the anti-slip grooves on the three rubber pads 31 staggered. This facilitates the smooth rotation of the simulator body 2 by the limiting plate 8 via the three rubber pads 31. A positioning ring 34 is fixedly installed on the outer side of the mounting rod 18, and an annular groove corresponding to the positioning ring 34 is provided on the inner side of the sleeve block 17. This allows the sleeve block 17 to pull the mounting rod 18 through the positioning ring 34, improving the stability of the mounting rod 18 during rotation.

[0023] Example 2: Please refer to Figures 2-6 This embodiment further illustrates Example 1. The receiving mechanism shown in the figure includes a push plate 9 disposed below the placement plate 7. The push plate 9 can synchronously bring the placement plate 7 closer to the simulator body 2. The receiving mechanism also includes two slide rods 22 symmetrically fixedly installed at the bottom of the placement plate 7. A sleeve 23 is slidably installed on the outer side of the slide rod 22. The bottom of the sleeve 23 contacts the top of the device base 1. Two symmetrically distributed pull rods 24 are fixedly installed between the side of the push plate 9 away from the placement plate 7 and the bottom of the slide 16. When the slide 16 moves, the pull rods 24 can drive the push plate 9 to move synchronously. The push plate 9 contacts the bottom of the placement plate 7, causing the push plate 9 to push the placement plate 7 to move upward synchronously. The slide rods 22 can move along the inner side of the sleeve 23, so that while the placement plate 7 moves upward, it maintains the distance between itself and the simulator body 2, making it easy for the placement plate 7 to catch the simulator body 2 after it separates from the limiting plate 8. A sleeve plate 25 is fixedly installed between the two sleeves 23. The surface of the sleeve plate 25 is open. A circular hole is provided for the opposite-direction screw 12 to pass through. Two symmetrically distributed connecting pipes 26 are fixedly installed between the sleeve plate 25 and the moving block 13. The connecting pipes 26 are slidably installed on the outside of the optical axis, so that when the moving block 13 moves, it can push the sleeve plate 25 to move synchronously through the connecting pipes 26. The sleeve plate 25 can then drive the placement plate 7 to move synchronously through the slide rod 22, so that the placement plate 7 can be adjusted to the corresponding position according to the size of the simulator body 2. A side plate 35 is fixedly installed on the top of the push plate 9. The side plate 35 is located on the placement plate 9. The side plate 35 is located below the side of the placement plate 7, so that when the push plate 9 moves upward, it can abut against the side of the placement plate 7, which facilitates the alignment of the push plate 9 with the placement plate 7. When the side plate 35 collides with the bottom of the placement plate 7, it is convenient for the staff to repair the push plate 9 in time. The top of the slide rod 22 is fixedly installed with a buffer pad 36, so that the placement plate 7 contacts the outside of the sleeve 23 through the buffer pad 36. After the placement plate 7 is separated from the push plate 9, the buffer pad 36 can provide cushioning for the contact between the placement plate 7 and the sleeve 23.

[0024] Example 3: Please refer to Figure 1 , Figure 7 and Figure 8 This embodiment further illustrates other embodiments. The angle adjustment mechanism shown in the figure includes a U-shaped frame 10 disposed outside the microcontroller 4. The U-shaped frame 10 enables the camera 5 to be adjusted according to the size of the simulator body 2. The angle adjustment mechanism also includes two positioning rods 27 symmetrically fixedly installed outside the microcontroller 4. The positioning rods 27 are rotatably installed inside the U-shaped frame 10. The U-shaped frame 10 is fixedly installed on the top inner wall of the gantry frame 3. A second gear 28 is fixedly installed at the end of the positioning rod 27 away from the microcontroller 4. Two third gears 29 are rotatably installed on the outside of the U-shaped frame 10, respectively meshing with the two second gears 28. The outer diameter of the third gear 29 is smaller than the outer diameter of the second gear 28, so that the rotational speed of the third gear 29 is greater than that of the second gear 28, and the length of the third gear 29 is greater than that of the second gear 28. Two symmetrically positioned positioning rods 27 are fixedly installed on the top of the mounting frame 14. The bracket 38 is distributed, and a second rack 30 is fixedly installed at the top of the bracket 38. The two second racks 30 mesh with two third gears 29 respectively. When the mounting frame 14 moves, the bracket 38 can drive the second racks 30 to move. The second racks 30 drive the second gears 28 to rotate through the third gears 29. The second gears 28 can drive the microcontroller 4 to swing through the positioning rod 27 to realize the angle adjustment of the camera 5. When the size of the simulator body 2 is small, the two cameras 5 can swing downward accordingly. Conversely, the two cameras 5 swing upward. This optimizes the shooting range for simulator bodies 2 of different sizes and improves detection accuracy. The U-shaped frame 10 has a baffle 37 fixedly installed on both sides, and the second rack 30 is slidably installed on the top of the baffle 37, so that the second rack 30 can move along the top of the baffle 37, improving the stability of the movement of the second rack 30.

[0025] Working principle: First, the operator places the simulator body 2 on two placement plates 7 and starts the drive motor, causing the drive motor to rotate the counter-rotating screw 12. The counter-rotating screw 12 drives two moving blocks 13 to move closer to each other along the outer side of the optical axis, causing the moving blocks 13 to move the mounting frame 14. The mounting frame 14 then moves the slide 16 on the electric telescopic rod 15. Under the limitation of the vertical groove on the mounting frame 14 against the pulley 19, the mounting frame 14 drives the sleeve block 17 to move synchronously with the slide 16. The mounting rod 18 on the inner side of the sleeve block 17 drives the limiting plate 8 to come close to the outer side of the simulator body 2, so that the limiting plate 8 pushes the rubber pad 31 against the simulator body 2 through the U-shaped rod 32. The outer sides of the simulator body 2 come into contact with each other. Utilizing the elasticity of the spring 33, the rubber pad 31 elastically clamps the outer side of the simulator. Simultaneously, the mounting frame 14 drives the two supports 38 to move synchronously. The supports 38 drive the second rack 30 to move along the top of the cover 37, causing the second rack 30 to drive the second gear 28 to rotate via the third gear 29. The second gear 28 drives the microcontroller 4 to swing via the positioning rod 27, causing the cameras 5 on the two microcontrollers 4 to be aligned with the outer side of the simulator body 2 in a crossed position. Then, the electric telescopic rod 15 pushes the slide 16 upward, causing the slide 16 to drive the sleeve block 17 upward. The two pulleys 19 on the outer side of the sleeve block 17 move along... The vertical slot on the mounting frame 14 moves upward, causing the limiting plate 8 to lift the simulator body 2 upward and away from the placement plate 7. Subsequently, the first gear 20 on the mounting rod 18 contacts the first rack 21, causing the first rack 21 to drive the mounting rod 18 to rotate via the first gear 20. The mounting rod 18 drives the simulator body 2 to flip via the limiting plate 8, allowing the two cameras 5 to capture images of the simulator body 2 in the flipped state. Simultaneously, the slide 16 drives the push plate 9 to move synchronously via the pull rod 24. The push plate 9 contacts the bottom of the placement plate 7, causing the push plate 9 to push the placement plate 7 upward synchronously. While moving the placement plate 7 upward, it maintains contact with the simulator body. The distance between 2 is then determined. Then, pulley 19 moves from the vertical groove of mounting frame 14 to the inclined groove, so that pulley 19 moves along the inclined groove. Pulley 19 pulls sleeve block 17 to move horizontally along the outside of slide 16. Sleeve block 17 drives the limiting plate 8 on mounting rod 18 away from simulator body 2, so that simulator body 2 falls on placement plate 7, which makes it easy for camera 5 to take pictures of the side of simulator body 2. Two cameras 5 can take pictures of simulator body 2 in a comprehensive manner, thereby achieving the effect of comprehensive inspection, ensuring the convenience and efficiency of the inspection process. The overall device effectively simplifies the operation steps and improves the efficiency and quality of surface defect inspection of simulator body 2.
