Technical Field
[0001] This invention relates to the field of control panel surface inspection technology, specifically to a control panel surface defect inspection device and method. Background Technology
[0002] The interior control panel of a commercial vehicle is the core operating component for functions such as the central control, seats, air conditioning, and lights. It typically adopts a curved, irregularly shaped, and high-gloss sprayed structure, with extremely high requirements for appearance quality. Even minor scratches, dents, color differences, and pitting defects on the surface can affect the overall interior quality and user experience.
[0003] Currently, the industry mostly uses manual visual inspection or fixed-position vision equipment to detect surface defects in the control panels of commercial vehicles. In the process of inspecting the control panels, traditional vision equipment uses a fixed ring light and fixed camera structure, which can only take pictures from the front and cannot cover curved surfaces, sides, corners, and groove areas, resulting in a large number of blind spots and a high rate of missed detection.
[0004] Meanwhile, traditional cameras are fixed vertical for shooting and cannot be adjusted in multiple angles or in all directions. The mirror-reflected light from the high-gloss panel shines directly onto the lens, resulting in low visibility of weak defects. To address the aforementioned problems, the inventors propose a control panel surface defect detection device and method to solve these issues. Summary of the Invention

Detailed Implementation
[0033] 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.
[0034] like Figure 1 - Figure 12 As shown, the present invention provides a control panel surface defect detection device, including a track base 1 and a control panel 5. Two rings 2 are respectively provided at both ends of the track base 1, and one of the rings 2 is slidably connected to the track base 1. Another ring 2 is rotatably connected to a circumferential adjustment mechanism 3, which extends between the two rings 2; A ring light 15 is installed on the inner side of the ring body 2, and a light shield 7 is rotatably connected to the inner wall of the ring body 2. The light shield 7 is connected to the circumferential adjustment mechanism 3. A non-circular connecting frame 11 connects the circumferential adjustment mechanism 3 to the movable ring 2; A universal adjustment mechanism 6 is installed on the outer wall of the irregular connecting frame 11. A camera 13 is connected to the bottom of the universal adjustment mechanism 6. The camera 13 and the light shield 7 are set to face each other. A clamping mechanism 4 for clamping the control panel 5 is provided between the track base frame 1 and the circumferential adjustment mechanism 3; In use, the control panel 5 is clamped by the clamping mechanism 4, the ring light 15 provides the light source, the camera 13 and the light shield 7 are set opposite each other, and the light shield 7 blocks half of the light source of the ring light 15 to prevent light from affecting the detection of the camera 13. The camera 13 is adjusted at multiple angles by the universal adjustment mechanism 6, so that the camera 13 can adapt to the light and be in the best light angle for detection.
[0035] The circumferential adjustment mechanism 3 includes a drive motor 31, which is mounted on the top of one end of the track base 1. A drive gear 32 is connected to the output shaft of the drive motor 31. A driven gear ring 33 meshes on the outer wall of the drive gear 32. The driven gear ring 33 is rotatably connected to the outer wall of the non-rotatable ring body 2. An upper groove rail 35 and a lower groove rail 34 are fixedly connected to the top and bottom of the outer wall of the driven gear ring 33, respectively. The purpose of this setup is to combine Figure 2 As shown, the output shaft of the drive motor 31 drives the drive gear 32 to rotate, the drive gear 32 drives the driven gear ring 33 to rotate, and drives the upper groove rail 35 and the lower groove rail 34 to perform circular motion, thereby driving the universal adjustment mechanism 6 and the camera 13 to perform circular motion adjustment on the outer wall of the ring body 2.
[0036] A stepper motor 9 is installed on the outer wall of the track base 1. A screw 10 is connected to the output shaft of the stepper motor 9. The two ends of the screw 10 are rotatably connected to the two ends of the track base 1. The screw 10 passes through a ring 2 and is threaded, so that the ring 2 slides between the track base 1, the lower groove rail 34 and the upper groove rail 35. A ring jet mechanism 8 is rotatably connected to the outer wall of the ring 2. The purpose of this setup is to combine Figure 3 As shown, the output shaft of the stepper motor 9 drives the screw 10 to rotate, and the screw 10 drives a ring 2 to move, thereby adjusting the distance between the two rings 2. This is used to adjust the position of the universal adjustment mechanism 6 and the camera 13. The ring jet mechanism 8 is set up to clean the surface of the control panel 5 by blowing air, further improving the detection effect.
[0037] One end of the irregular connecting frame 11 is slidably connected to the upper groove rail 35, and the other end of the irregular connecting frame 11 is slidably connected to the outer wall annular groove of the ring body 2; This configuration allows the circumferential adjustment mechanism 3 to drive the irregular connecting frame 11, so that while the ring body 2 is in circular motion, it can also be driven by the stepper motor 9 and the screw 10 to move horizontally on the upper groove rail 35 via the irregular connecting frame 11, so that the circular motion and the horizontal motion do not interfere with each other. The universal adjustment mechanism 6 includes a servo motor 61 and two bevel gears 66. The servo motor 61 is mounted on the outer wall of the irregular connecting frame 11. A transmission rod 67 is slidably connected to the output shaft of the servo motor 61. A cam ring 673 is fixedly connected to the transmission rod 67. A second gear 64 is slidably connected to the outer wall of the cam ring 673. The second gear 64 is rotatably connected to the outer wall of the irregular connecting frame 11. A gear ring 62 is fixedly connected to the outer wall of the irregular connecting frame 11. A first gear 63 meshes with the outer wall of the second gear 64. The first gear 63 meshes between the second gear 64 and the gear ring 62. One end of the transmission rod 67 is slidably connected to the sleeve rod 660, and a Z-shaped connecting rod 65 is rotatably connected to the outer wall of the first gear 63. The Z-shaped connecting rod 65 is fixedly connected to the outer wall of the sleeve rod 660. One of the bevel gears 66 is fixedly connected to one end of the sleeve rod 660, and the shaft of the other bevel gear 66 is rotatably connected to the bottom end of the Z-shaped connecting rod 65. The two bevel gears 66 mesh perpendicularly with each other, and the camera 13 is connected to the shaft of the bevel gear 66. The purpose of this setup is to combine Figure 6 - Figure 9 As shown, the output shaft of the servo motor 61 drives the transmission rod 67 to rotate. The transmission rod 67 drives the second gear 64 to rotate through the cam ring 673. The second gear 64 meshes with the gear ring 62 through the first gear 63. The first gear 63 performs circumferential motion inside the gear ring 62. The first gear 63 is rotatably connected to the Z-shaped connecting rod 65, which drives the sleeve rod 660 to rotate at one end of the transmission rod 67, thereby driving the camera 13 to rotate in the axial direction of the transmission rod 67 and adjusting the angle in the horizontal direction.
[0038] An electric telescopic rod 14 is connected to the outer wall of the irregular connecting frame 11. An L-shaped connecting rod 141 is connected to the output end of the electric telescopic rod 14. A grooved ring 672 is fixedly connected to the outer wall of the transmission rod 67. One end of the L-shaped connecting rod 141 is rotatably connected to the grooved ring 672. The inner wall of the sleeve rod 660 is provided with several spherical grooves 661, and several spheres 671 are fixedly connected to the outer wall of the transmission rod 67; The purpose of this configuration is that the output end of the electric telescopic rod 14 extends and retracts, and the L-shaped connecting rod 141 drives the transmission rod 67, the grooved ring 672 and the cam ring 673 to move. The cam ring 673 disengages from the inside of the second gear 64, at which point the second gear 64 loses power. The transmission rod 67 drives the ball 671 to approach the spherical groove 661. At this time, the output shaft of the servo motor 61 drives the sleeve rod 660 and the bevel gear 66 through the transmission rod 67, thereby driving the two bevel gears 66 to mesh and transmit power, thereby driving the camera 13 to follow one bevel gear 66 to rotate and adjust in the vertical direction. In combination with the above, the camera 13 can be rotated at multiple angles in both the horizontal and vertical directions to adapt the camera 13 to the light conditions at different positions.
[0039] A cow horn cover 12 is fitted on the outside of the camera 13. The top of the cow horn cover 12 is cone-shaped and the bottom is narrow. The purpose of this design is that the special shape of the bull horn cover 12, with its cone-shaped top and narrow bottom, forms a one-way light-entry channel, allowing only effective diffused light from the control panel 5 to enter the lens, completely blocking the side spill light of the ring light 15, diffused light from the inner wall of the equipment, reflected light from the surface of the light shield 7, and stray light from the workshop environment.
[0040] Suppressing interference from ring lights or cross-beaming light in the narrow aperture directly facing the shooting area, limiting the light-incoming angle, physically isolating the direct light from the opposite ring light and the diffused light from adjacent light sources from entering the lens, forming a double light shielding inside and outside with the light shield 7, completely eliminating overexposure and whitening problems caused by light source cross-beaming and cross-beaming light. The horn-shaped design, which expands outward at the top and narrows at the bottom, perfectly matches the omnidirectional tilt angle adjustment of the camera 13. This not only narrows the range of stray light incident but also does not obstruct the effective imaging field of view. The narrow opening design reduces the amount of external dust and debris that falls directly onto the lens surface of the camera 13, reducing the probability of lens contamination, reducing black spots and blurring issues in the image, extending the lens lifespan, and ensuring imaging stability.
[0041] A driven gear 36 is rotatably connected to the top of the track base 1. The drive gear 32 meshes with the driven gear 36. Two sets of clamping mechanisms 4 are provided. One set of clamping mechanisms 4 is fixedly connected to the outer wall of the driven gear 36. A support ring frame 16 is slidably connected to the bottom outer wall of the track base 1. The other set of clamping mechanisms 4 is rotatably connected to the top of the support ring frame 16. The purpose of this setup is to combine Figure 1 - Figure 4 As shown, the driven gear 36 is driven by the drive gear 32. During the driving process, the driven gear 36 and the driven gear ring 33 rotate in opposite directions. When used in conjunction with the clamping structure of the clamping mechanism 4, when the circumferential adjustment mechanism 3 drives the camera 13 to move clockwise, the control panel 5 and the clamping mechanism 4 rotate counterclockwise, so that the flipping can be quickly adjusted and the convenience of flipping detection of the control panel 5 can be improved.
[0042] The clamping mechanism 4 includes a slot plate 41, a tension spring 42 and a clamping plate 43. The two clamping plates 43 are slidably connected to the slot plate 41, and the two tension springs 42 are disposed inside the slot plate 41. The two ends of the control panel 5 are clamped by the clamping plates 43 of the two sets of clamping mechanisms 4. The purpose of this setup is to adaptively clamp both ends of the control panel 5 using two clamping plates 43 in conjunction with tension springs 42.
[0043] A connecting block 71 is fixedly connected to the outer wall of the light-shielding plate 7. The light-shielding plate 7 is slidably connected to the lower groove rail 34 through the connecting block 71. While the light-shielding plate 7 rotates inside the ring body 2, it can slide on the lower groove rail 34. The rotation and sliding do not interfere with each other. A pressure plate 21 is fixedly connected to the top outer wall of the ring body 2. The annular jet mechanism 8 includes an annular air shell 81, which is rotatably connected to the outer wall of the ring body 2. The annular air shell 81 is slidably connected to the lower groove rail 34. An air inlet 82 is connected to the outer wall of the annular gas shell 81. The interior of the air inlet 82 is hollow. A T-shaped rod 83 is slidably connected through the annular gas shell 81. A valve body 86 is connected to the outer wall of the annular gas shell 81. A valve core 84 is slidably connected to the inner wall of the valve body 86. A gap is left between the valve core 84 and the valve body 86. A return spring 85 is installed inside the valve body 86. The valve core 84 is connected to one end of the T-shaped rod 83. The T-shaped rod 83 contacts and engages with the pressure plate 21. The purpose of this configuration is that the annular jet mechanism 8 follows the lower groove rail 34 to perform circular motion on the ring body 2, and the annular jet mechanism 8 performs relative sliding adjustment on the lower groove rail 34. During the rotational connection of the annular gas housing 81 on the outer wall of the ring body 2, the T-shaped rod 83 contacts and engages with the pressure plate 21, squeezing the return spring 85 and opening the valve core 84. High-pressure gas is continuously introduced into the annular gas housing 81 through the external air pump to the air inlet 82. During the rotation of the annular gas housing 81, the camera 13 rotates synchronously, and the corresponding valve body 86 port opens, spraying out high-pressure gas to blow air and clean the control panel 5 at that position, further improving the detection accuracy.
[0044] A method for using a control panel surface defect detection device includes the following steps: Step 1: First, the stepper motor 9 drives the screw 10 to rotate, which drives the ring 2 to move. Adjust the distance between the two rings 2, and clamp the control panel 5 through the clamping mechanism 4. Step 2: The circumferential adjustment mechanism 3 drives the universal adjustment mechanism 6, the light shield 7, the ring jet mechanism 8 and the camera 13 to rotate on the outer wall of the ring body 2. At the same time, the clamping mechanism 4 and the control panel 5 rotate in the opposite direction under the action of the circumferential adjustment mechanism 3 to facilitate flipping. Step 3: The light shield 7 and the camera 13 are set facing each other to block half of the light from the ring light 15. The horn cover 12 is used to focus the light and filter stray light. The camera 13 is adjusted to different angles through the universal adjustment mechanism 6.
[0045] Working principle: First, start the stepper motor 9 to drive the screw 10 to rotate, which drives one side ring 2 to move laterally along the track base 1, thereby adjusting the distance between the two rings 2 to fit control panel 5 of different lengths. Then, put both ends of the control panel 5 into the slot plate 41 of the clamping mechanism 4, and the tension spring 42 pushes the clamping plate 43 to adaptively clamp the workpiece, completing the positioning and clamping.
[0046] After clamping, the drive motor 31 is started, and its output shaft drives the drive gear 32 to rotate. The drive gear 32 meshes with the driven gear ring 33, causing the driven gear ring 33 and the upper and lower groove rails 35 and 34 fixed on it to rotate in the forward direction. This, in turn, causes the irregular connecting frame 11, the universal adjustment mechanism 6, the camera 13, the light shield 7, and the ring jet mechanism 8 to move in a circular motion around the outside of the control panel 5. On the other hand, the drive gear 32 simultaneously meshes with the driven gear 36, causing the driven gear 36 and the connected clamping mechanism 4 and control panel 5 to rotate in the reverse direction. This achieves the reverse synchronous rotation of the camera 13 and the control panel 5, and a single rotation can complete the full-area detection of both the front and back sides.
[0047] During the circular motion, the light shield 7 rotates synchronously with the lower groove rail 34 through the connecting block 71, always facing the camera 13, blocking the direct light from the ring light 15 towards the camera side in real time, eliminating the interference of ring light beam and cross-beaming light from the source.
[0048] Simultaneously, the annular jet mechanism 8 rotates synchronously with the lower groove rail 34, and the pressure plate 21 intermittently presses against the T-shaped rod 83, pushing the valve core 84 to compress the reset spring 85, thereby opening the valve body 86; the external air source enters the annular air shell 81 through the air inlet 82, and the high-pressure gas blows the surface of the current area to be detected in a directional manner to remove dust and debris. After the T-shaped rod 83 leaves the pressure plate 21, the reset spring 85 resets, the valve core 84 closes, and the jet stops, avoiding airflow disturbance to the imaging.
[0049] During the inspection process, the universal adjustment mechanism 6 can adjust the camera 13 at multiple angles. The servo motor 61 drives the transmission rod 67 to rotate. The transmission rod 67 drives the second gear 64 to revolve and rotate through the cam ring 673. The first gear 63 meshes and transmits power in the gear ring 62. The Z-shaped connecting rod 65 drives the sleeve rod 660 to swing horizontally. The electric telescopic rod 14 extends and retracts, driving the L-shaped connecting rod 141 to pull the transmission rod 67 to move axially, so that the ball 671 meshes with the spherical groove 661, driving the bevel gear 66 to rotate vertically. Finally, the camera 13 can be tilted and horizontally finely adjusted in all directions to accurately avoid the reflection light from the workpiece mirror.
[0050] The camera 13 is fitted with a cow horn cover 12. Its special structure, with a cone-shaped top and a narrow opening at the bottom, allows only the effective diffused light from the surface of the control panel 5 to enter the lens, completely blocking the side scattering light from the ring light 15, the reflection from the inner wall of the equipment, and the stray light from the surface of the light shield 7. Together with the light shield 7, it forms a double light shielding inside and outside, ensuring pure and clear imaging.
[0051] With the coordinated operation of circumferential rotation, reverse flipping, follow-up dust removal, dynamic shading, omnidirectional angle adjustment, and pure imaging, the equipment completes high-precision defect detection of the entire 360° area of the control panel 5, without blind spots, dust, or stray light. After the detection is completed, the equipment is reset, the workpiece is unloaded, and the next detection cycle begins.
[0052] All standard mechanical parts used in this invention can be purchased commercially, and irregularly shaped parts can be custom-made according to the description and drawings. The specific mechanical connection methods for each part can employ conventional methods such as bolts, rivets, and welding, which are already well-established in the prior art.
