Description

Technical Field

[0001] This invention relates to the field of testing technology, and in particular to a machine vision-based device for testing the performance of automotive dashboards. Background Technology

[0002] The automotive dashboard is a component that integrates information such as vehicle speed, RPM, fuel level, coolant temperature, and fault warnings. It consists of a housing, cover, PCB board, LEDs, pointers, and display screen. After production, it requires performance testing to verify the display, electrical, structural, and environmental adaptability, eliminate defects such as poor soldering, missing lights, looseness, and poor contact, and ensure reliability. The testing is completed using a fully automatic dashboard performance testing machine. During use, the dashboard is positioned, and then the wiring plug of the performance testing machine is inserted into the socket on the back of the dashboard. The performance testing machine can then perform testing on the dashboard.

[0003] While testing dashboard performance, visual inspection of the dashboard display surface is necessary to prevent defects. However, some minor defects are difficult to detect visually. Furthermore, vibrations during dashboard transportation, installation, or use can negatively impact performance or characteristics, especially noticeable with minor defects (such as cold solder joints, false solder joints, or looseness). Existing technologies, such as CN111239158A and CN221764516U, do not consider how to reveal these minor defects during testing, leading to false positives. Additionally, existing technologies are prone to stray light during dashboard inspection and do not incorporate changes in lighting conditions for image acquisition and detection, resulting in incomplete and inaccurate results. Moreover, current dashboard performance testing devices are often standalone devices, lacking effective dust removal components or having these components separated from the testing device, failing to effectively remove dust during testing. Therefore, this application provides a machine vision-based automotive dashboard performance testing device to meet these requirements. Summary of the Invention

[0004] This invention provides a machine vision-based automotive dashboard performance testing device to address the problem that some minor defects on the dashboard surface are difficult to detect with the naked eye, and to solve the problem that tiny defects inside the dashboard are difficult to reveal, such as poor soldering, false soldering, or looseness in LEDs, PCBs, pins, and ribbon cables, which can lead to false acceptance and affect the accuracy of the test results. In addition, it also solves the problem that the test results obtained from detecting stray light and single light sources are not precise or comprehensive enough, and solves the problem of removing dust during the testing process to improve the testing accuracy.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A machine vision-based automotive dashboard performance testing device includes a detector, the surface of which is electrically connected to a connector via wires, and further includes: The testing mechanism includes an industrial camera, which is fixedly mounted on the top of the detector support platform. The detector support platform is provided with a support component located around the industrial camera. The support component includes a fixed sleeve fixed to the detector support platform. An outer sleeve is movably fitted onto the outer wall of the fixed sleeve. A support ring is fixed to the inner wall of the outer sleeve. The support ring is used to support the instrument panel. In use, the instrument panel is placed upside down on the support assembly, and an industrial camera inspects the instrument panel.

[0006] Preferably, the inner wall of the outer sleeve is provided with a driving component, which is used to drive the outer sleeve to move up and down on the fixed sleeve surface.

[0007] Preferably, the drive assembly includes a rack fixed to the inner wall of the outer casing, the bottom of the rack movably penetrating the support platform of the detector, a motor is fixed to the top of the inner wall of the detector support platform, a round rod is fixed to the output end of the motor, a square hole is opened at the end of the round rod, a square rod is inserted into the inner wall of the square hole, a gear is fixed to the end of the square rod, the round rod, the square rod, and the gear are coaxial in the horizontal direction, the gear meshes with the rack, multiple grooves are opened on the surface of the rack, the multiple grooves are arranged vertically, an electric push rod is fixed to the top of the inner wall of the detector support platform, the output end of the electric push rod is rotatably connected to the end of the gear through a bearing seat, and the electric push rod is coaxial with the gear.

[0008] Preferably, the top of the outer cover is integrally formed with a guide portion, which is used to guide the instrument panel into the outer cover.

[0009] Preferably, the outer jacket has a through hole on its side, which is located below the support ring, and a light-shielding component is provided on the outer wall of the outer jacket at the through hole.

[0010] Preferably, a guide plate is fixed to the inner wall of the outer jacket at the through hole, and the guide plate is inclined upward.

[0011] Preferably, a sealing ring is fixed to the inner wall of the outer sleeve, and the sealing ring is located above the support ring.

[0012] Preferably, the top of the sealing ring is provided with a guide surface, which is used to guide the instrument panel to be inserted into the sealing ring, and the outer wall of the fixing sleeve is provided with an elastic extrusion material.

[0013] Preferably, a limiting block is fixed on the smooth side of the rack, and after the outer sleeve rises to the highest point, the top of the limiting block is attached to the top of the inner wall of the detector support platform.

[0014] Preferably, the light-shielding component includes an L-shaped tube disposed at the through hole, the L-shaped tube being fitted to the outer wall of the outer jacket, and a sealing ring being provided on the end face of the L-shaped tube that is fitted to the outer wall of the outer jacket. The sealing ring is fitted to the through hole, the L-shaped tube is connected to the through hole, and a second motor is fixed to the end of the L-shaped tube away from the sealing ring. The second motor is fixed to the outer surface of the outer jacket.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a testing mechanism, the instrument panel is placed upside down on the support component during testing, and the wiring plug is inserted into the wiring terminal of the instrument panel for performance testing. Subsequently, while the detector is testing the instrument panel, the industrial camera can simultaneously take pictures of the display surface of the instrument panel for testing, eliminating the need for manual observation and testing. The industrial camera can distinguish minor defects such as bright spots, dark spots, and color differences, resulting in higher testing accuracy.

[0016] By setting up support components, the outer casing and fixing sleeve support the instrument panel while also providing light shielding, creating a dark chamber for detection within the testing device. This reduces external stray light and reflection interference, preventing image overexposure and blurring of details, which could lead to misjudgment or missed detection. After light shielding, the darker environment eliminates stray light reflection, improves the contrast of the display area, and ensures clear and stable images without external interference. This guarantees the authenticity and accuracy of the images captured by the industrial camera, improving detection precision and consistency.

[0017] By setting up a drive component, during the process of the outer casing supporting the dashboard, the motor synchronously drives the gear to rotate. The gear drives the rack to move downwards, and the rack drives the outer casing to move downwards. When the gear moves to the groove, the gear and rack lose mesh, and the rack and outer casing will fall downwards quickly until the gear contacts the rack again. At the moment the gear contacts the rack again, the outer casing and dashboard will vibrate. The vibration can simulate the bumps of a car in motion. When there are poor soldering, false soldering, or looseness in the LEDs, PCBs, pins, and ribbon cables inside the dashboard, these problems can be exposed by vibration. Compared with static testing, the detection is more thorough and the accuracy is higher.

[0018] By incorporating a through-hole and a light-shielding component, motor two drives the L-shaped tube to rotate, causing the end of the L-shaped tube with the sealing ring to disengage from the through-hole. This allows external light to pass through the through-hole and enter the outer casing, increasing its brightness and facilitating the industrial camera's observation of scratches and other defects. The alternating light and dark environment of the industrial camera ensures the accuracy of the instrument panel inspection. Before the outer casing moves upward, motor two drives the L-shaped tube to rotate in the opposite direction and fit against the through-hole, preventing external light from entering the outer casing. Simultaneously, during the upward movement of the outer casing, since the detection device is sealed or nearly sealed except for the channel formed by the through-hole and the L-shaped tube, the internal air pressure decreases. External air enters through the L-shaped tube, passes through the through-hole, and blows onto the surface of the instrument panel, cleaning it and forcibly removing dust. The industrial camera then inspects the instrument panel again, further improving the accuracy of the inspection.

[0019] By setting up a guide plate, the air entering through the through hole comes into contact with the guide plate, and the guide plate can guide the air to flow towards the dashboard, improving the cleaning effect of dust. Attached Figure Description

Detailed Implementation

[0023] The following is a detailed description of a machine vision-based automotive dashboard performance testing device provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0024] like Figures 1-7 As shown, an embodiment of the present invention provides a machine vision-based automotive dashboard performance testing device, including a detector 1, the surface of which is electrically connected to a connector 23 via wires, and further including: The detection mechanism 2 includes an industrial camera 3, which is fixedly mounted on the top of the support platform of the detector 1.

An outer sleeve 5 is movably fitted onto the outer wall of the fixed sleeve 4. A support ring 6 is fixed to the inner wall of the outer sleeve 5. The support ring 6 is used to support the instrument panel. The fixed sleeve 4 is fixed to the support platform of the detector 1 to provide support and guidance for the outer sleeve 5, ensuring that the outer sleeve 5 can move up and down stably and preventing the outer sleeve 5 from shifting. The outer sleeve 5 is movably fitted onto the outer wall of the fixed sleeve 4 to wrap the instrument panel, which plays a role in shielding light, reducing interference from external stray light, and protecting the instrument panel from collision damage during the detection process. The support ring 6 is fixed to the inner wall of the outer sleeve 5 to directly support the inverted instrument panel, keeping the instrument panel in a horizontal state, ensuring that the industrial camera 3 can accurately capture the image of the instrument panel display surface, and avoiding image blurring or incomplete acquisition caused by the tilt of the instrument panel. In use, the instrument panel is placed upside down on the support assembly 19. The industrial camera 3 inspects the instrument panel. The detector 1, as the main body of the inspection device, receives the instrument panel's operating parameters transmitted by the connector 23, analyzes and judges the instrument panel's performance, and outputs the inspection results. The connector 23 is electrically connected to the detector 1 via a wire and is used to insert into the instrument panel's terminals to supply power to the instrument panel. It also transmits the instrument panel's operating parameters to the detector 1 to achieve instrument panel performance inspection. The inspection mechanism 2 is used to automate the inspection of the instrument panel's appearance, replacing manual visual inspection and improving inspection accuracy and efficiency. The industrial camera 3 is fixedly mounted on the top of the support platform of the detector 1 and is used to capture images of the instrument panel's display surface. It can capture minute defects such as bright spots, dark spots, and color differences that are difficult to distinguish with the naked eye, providing clear image evidence for the detector 1's analysis and judgment. The support assembly 19 is set around the industrial camera 3 to support the upside-down instrument panel, ensuring the instrument panel is placed stably and enabling the industrial camera 3 to accurately align with the instrument panel's display surface, ensuring the accuracy of image acquisition.

[0025] like Figure 3 As shown in this embodiment, the top of the outer casing 5 is integrally formed with a guide portion 7. The guide portion 7 is used to guide the instrument panel to be inserted into the outer casing 5. The guide portion 7 is integrally formed on the top of the outer casing 5 and is flared or inclined. It is used to guide the instrument panel to be inserted into the outer casing 5 quickly and smoothly, avoiding jamming or displacement when the instrument panel is inserted, and at the same time protecting the edge of the instrument panel to prevent scratching the instrument panel when it is inserted.

[0026] like Figure 2 and Figure 6 and Figure 7As shown, in this embodiment, the inner wall of the outer sleeve 5 is provided with a driving assembly 20. The driving assembly 20 is used to drive the outer sleeve 5 to move up and down on the surface of the fixed sleeve 4. The driving assembly 20 includes a rack 8 fixed to the inner wall of the outer sleeve 5. The bottom of the rack 8 movably passes through the support platform of the detector 1. A limit block 22 is fixed on the smooth side of the rack 8. After the outer sleeve 5 rises to the highest point, the top of the limit block 22 fits against the top of the inner wall of the support platform of the detector 1. A motor 9 is fixed to the top of the inner wall of the support platform of the detector 1. A round rod 25 is fixed to the output end of the motor 9. A square hole is opened at the end of the round rod 25. The inner wall of the square hole A square rod 26 is inserted, and a gear 10 is fixed to the end of the square rod 26. The round rod 25, the square rod 26, and the gear 10 are coaxial in the horizontal direction. The gear 10 meshes with the rack 8. One or more grooves 11 are formed on the surface of the rack 8, and the grooves 11 are arranged vertically. An electric push rod 12 is fixed to the top of the inner wall of the support platform of the detector 1. The output end of the electric push rod 12 is rotatably connected to the end of the gear 10 through a shaft seat. The electric push rod 12 is coaxial with the gear 10. The rack 8 is fixed to the inner wall of the outer sleeve 5 for meshing with the gear 10, transmitting power, and driving the outer sleeve 5 to move up and down. The bottom of the rack 8 is movable through the gear 10. The detector 1 support platform ensures that the rack 8 can move smoothly up and down; the limit block 22 is fixed to the smooth side of the rack 8 to limit the rising height of the outer sleeve 5, preventing the outer sleeve 5 from rising too high and causing damage to the components, and ensuring that the outer sleeve 5 remains stable after rising to the highest point; the motor 9 is fixed to the top of the inner wall of the detector 1 support platform to provide driving power and drive the round rod 25 to rotate; the round rod 25 is fixed to the output end of the motor 9, and the square hole at the end is used to insert the square rod 26 to realize power transmission, while allowing the square rod 26 to move laterally along the square hole; the square rod 26 is inserted into the square hole of the round rod 25, and the end is fixed with a tooth. Wheel 10 is used to transmit the power of motor 9 to drive gear 10 to rotate; gear 10 meshes with rack 8 to drive rack 8 to move up and down; groove 11 is formed on the surface of rack 8 to temporarily disengage rack 8 from gear 10 during the process of gear 10 driving rack 8 to descend and driving outer sleeve 5 to descend, so that rack 8 and outer sleeve 5 fall quickly under the action of gravity and generate vibration; electric push rod 12 is fixed to the top of the inner wall of the support platform of detector 1, and the output end is rotatably connected to gear 10 through shaft seat to push gear 10 to move laterally reciprocally and switch the meshing position of gear 10 and rack 8.

[0027] like Figure 5As shown, in this embodiment, a through hole 13 is provided on the side of the outer jacket 5. The through hole 13 is located below the support ring 6. A light-shielding component 21 is provided on the outer wall of the outer jacket 5 at the through hole 13. The through hole 13 is provided on the side of the outer jacket 5 and below the support ring 6 to allow external light to enter the outer jacket 5, thereby increasing the brightness inside the outer jacket 5 and facilitating the industrial camera 3 to detect minor defects such as scratches on the surface of the instrument panel. At the same time, during the process of the gear 10 driving the rack 8 to rise rapidly and driving the outer jacket 5 to rise rapidly, since the detection device is in a sealed or relatively sealed state except for the channel formed by the through hole, the internal air pressure of the device is reduced, allowing outside air to enter and cleaning the dust on the surface of the instrument panel. The light-shielding component 21 is provided at the through hole 13 on the outer wall of the outer jacket 5 to control the opening and closing of the through hole 13, thereby switching the light and dark environment inside the outer jacket 5. At the same time, it seals the through hole 13 to prevent interference from external stray light and can also guide air into the outer jacket 5. like Figures 1-6 As shown, in this embodiment, the light-shielding component 21 includes an L-shaped tube 15 disposed at the through hole 13. The L-shaped tube 15 is fitted to the outer wall of the outer sleeve 5, and a sealing ring 18 is provided on the end face of the L-shaped tube 15 that is fitted to the outer wall of the outer sleeve 5. The sealing ring 18 is fitted to the through hole 13, and the L-shaped tube 15 is connected to the through hole 13. A motor 2 16 is fixed to the end of the L-shaped tube 15 away from the sealing ring 18. The motor 2 16 is fixed to the surface of the outer sleeve 5. The L-shaped tube 15 is disposed at the through hole 13 to control the opening and closing of the light at the through hole 13, and at the same time guides... Outside air enters the outer casing 5 to clean dust; motor 2 16 is fixed to the surface of the outer casing 5 and fixedly connected to the lower side of the L-shaped tube 15, used to drive the L-shaped tube 15 to rotate, so that the end of the L-shaped tube 15 away from the sealing ring 18 can be engaged or disengaged from the through hole 13; the sealing ring 18 is located at the contact surface between the L-shaped tube 15 and the outer casing 5, used to seal the gap between the L-shaped tube 15 and the through hole 13, preventing outside light from entering through the gap, and preventing air leakage; the L-shaped tube 15 is connected to the through hole 13 to ensure that air can smoothly enter the outer casing 5.

[0028] like Figure 5 As shown in this embodiment, a guide plate 14 is fixed to the inner wall of the outer sleeve 5 below the through hole 13. The guide plate 14 is inclined upward and fixed to the inner wall of the outer sleeve 5 below the through hole 13. It is inclined upward and is used to guide the air entering from the through hole 13 to flow towards the instrument panel, thereby improving the cleaning effect of the air on the surface of the instrument panel. At the same time, after the L-shaped tube 15 rotates and disengages from the through hole 13, the setting of the guide plate 14 can prevent the light entering from the through hole 13 from being dissipated, thereby improving the image acquisition effect.

[0029] like Figure 5As shown in this embodiment, a sealing ring 17 is fixed to the inner wall of the outer sleeve 5. The sealing ring 17 is located above the support ring 6. The sealing ring 17 is fixed to the inner wall of the outer sleeve 5 and located above the support ring 6. It is used to seal the gap between the instrument panel and the outer sleeve 5 to prevent external light from entering the outer sleeve 5 through the gap, and at the same time to prevent air from leaking through the gap, thereby improving the dust cleaning effect and ensuring the stability of dark environment detection. The outer wall of the fixing sleeve 4 is provided with an elastic extrusion material so that there is no gap between the outer sleeve 5 and the fixing sleeve 4. This is used to prevent external air from entering through the gap when the outer sleeve 5 moves upward, and also to prevent stray light from entering during dark environment detection. Furthermore, the fixing sleeve 4 and the support platform of the detector 1 are sealed and fixed. All parts of the support platform of the detector 1 are also sealed.

[0030] like Figure 5 As shown in this embodiment, a guide surface 24 is provided on the top of the sealing ring 17. The guide surface 24 is used to guide the instrument panel to be inserted into the sealing ring 17. The guide surface 24 is provided on the top of the sealing ring 17 and is inclined. It is used to guide the instrument panel to be inserted into the sealing ring 17 quickly and smoothly, so as to avoid jamming or friction between the instrument panel and the sealing ring 17 when it is inserted, and improve the smoothness of operation.

[0031] Working process: In the initial state, the end of the L-shaped tube 15 with the sealing ring 18 is attached to the through hole 13, the gear 10 is below the groove 11 and meshes with the rack 8. After forming a dark chamber for testing in the testing device, the instrument panel to be tested is inverted. The instrument panel is guided into the outer sleeve 5 through the guide part 7 at the top of the outer sleeve 5 and the guide surface 24 of the sealing ring 17, so that the bottom of the instrument panel is attached to the support ring 6. The sealing ring 17 is attached to the edge of the instrument panel to achieve a seal. The wiring plug 23 of the detector 1 is connected to the wiring terminal of the instrument panel through the wire to power the instrument panel performance test. Start industrial camera 3 to take preliminary pictures of the instrument panel display surface and capture images of the instrument panel in a dark environment in its initial static state to check for obvious defects on the surface. Start motor 2 16, which drives L-shaped tube 15 to rotate in the opposite direction. The end of L-shaped tube 15 with sealing ring 18 is away from through hole 13. External light enters the outer jacket 5 through through hole 13, increasing the brightness inside the outer jacket 5. Industrial camera 3 takes another picture for inspection, realizing comprehensive inspection in both bright and dark environments. After testing under illumination, motor 16 is restarted. Motor 16 rotates and drives L-shaped tube 15 to reset. One end of L-shaped tube 15 with sealing ring 18 is attached to through hole 13. Start motor 9. Motor 9 drives gear 10 to rotate. Gear 10 drives rack 8 to move downward. Rack 8 drives outer sleeve 5 and instrument panel to move downward synchronously. When gear 10 rotates to the groove 11 of rack 8, gear 10 disengages from rack 8. Rack 8 and outer sleeve 5 fall rapidly downwards under the action of gravity until gear 10 re-engages with rack 8. At the moment gear 10 contacts rack 8 again, outer sleeve 5 and dashboard vibrate, simulating the bumpy state of a car driving. If there are poor soldering, false soldering, or looseness in LEDs, PCBs, pins, or ribbon cables inside the dashboard, the vibration will expose these problems. Industrial camera 3 simultaneously captures images during and after the vibration, and compares this with images captured only in the initial static state to achieve more thorough detection and improve detection accuracy. After the vibration test is completed, motor 19 continues to drive gear 10 to rotate, causing the outer sleeve 5 to move downward to the lowest point. Motor 216 is then started, and motor 216 drives L-shaped tube 15 to rotate in the opposite direction. One end of L-shaped tube 15 with sealing ring 18 disengages from through hole 13, and external light enters the inner sleeve 5 through through hole 13, increasing the brightness inside the outer sleeve 5. This makes it easier for industrial camera 3 to detect minor defects such as scratches on the surface of the instrument panel. Industrial camera 3 takes another picture for inspection, achieving comprehensive inspection in both bright and dark environments. After testing under illumination, motor 16 is restarted. Motor 16 rotates and drives L-shaped tube 15 to reset. One end of L-shaped tube 15 with sealing ring 18 is attached to through hole 13. During the above testing process, detector 1 performs performance testing on the instrument panel through connector 23 and simultaneously collects the working parameters of the instrument panel. Industrial camera 3 transmits the collected images under static, vibrating, and bright / dark environments to detector 1. Detector 1 analyzes the images, identifies minor defects such as missing brightness, dark spots, color differences, and scratches, and combines the performance test data to complete a comprehensive test of the instrument panel's performance and appearance, and determines whether the instrument panel is qualified. After the test is completed, start the electric push rod 12. The electric push rod 12 pushes the gear 10 to move laterally to the position of the rack 8 without the groove 11, so that the gear 10 and the rack 8 are stably meshed. Start the motor 9. The motor 9 drives the gear 10 to rotate in the opposite direction. The gear 10 drives the rack 8 to move upward quickly. The rack 8 drives the outer sleeve 5 to rise quickly to the highest point. During the rapid ascent of the outer casing 5, since the detection device is sealed or nearly sealed except for the channel formed by the through hole and the L-shaped tube, the internal air pressure of the device decreases. Outside air enters through the L-shaped tube 15 and is blown into the outer casing 5 through the through hole 13. After the air comes into contact with the inclined guide plate 14, it is guided by the guide plate 14 to the direction of the instrument panel, forcibly blowing away the dust on the surface of the instrument panel. Then the industrial camera 3 is restarted for detection to further ensure the accuracy of the detection. After moving the outer cover 5 to the top, remove the wiring plug 23 and take out the completed instrument panel from inside the outer cover 5.

[0032] It should be noted that the camera component of this application has an automatic precision focusing function, which ensures that a clear image is captured throughout the entire process of the outer jacket 5's descent and ascent. Other settings not detailed in this application are common in the art and will not be elaborated here.

[0033] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
