Description

Technical Field

[0001] The present invention relates to a detection system and a detection method thereof, specifically an on-line quality detection system and method for automotive panel components, belonging to the technical field of detection systems. Background Art

[0002] The automotive panel mainly refers to the control panel inside the vehicle, which is usually located in the center console area and integrates various function buttons and display screens for controlling various functions of the vehicle, such as air conditioning, audio, navigation, etc. The automotive panel is an important part of the vehicle interior, integrating various control buttons and display screens, providing an intuitive and convenient operation interface for drivers and passengers.

[0003] By detecting the automotive panel, functional failures on the panel can be promptly discovered and repaired, ensuring the normal operation of various functions, and improving driving safety and comfort. As an important interface for drivers and passengers to interact with the vehicle, the quality and performance of the automotive panel directly affect the user experience. Through detection, it can be ensured that the buttons on the panel are sensitive and the display screen is clear, thus enhancing the user experience.

[0004] It is known that the Chinese published invention (Publication No.: CN118758859A) discloses an on-line automatic recognition and measurement system and method for the quality of automotive interior products, which can realize the on-line measurement of the gaps, step differences, and flatness of specified positions of interior products, compare with standards for judgment, automatically lock and alarm when defects are found, prevent defective parts from flowing out, and can completely replace manual inspection in cooperation with the vision module;

[0005] It is known that the Chinese authorized utility model (Publication No.: CN214041193U) discloses an automotive interior defect detection device, which places the automotive interior parts to be detected on a jig, then takes pictures through the vision module, and performs defect recognition through a control computer. If qualified, a qualified label is printed. This utility model is provided with a three-axis module and upper and lower vision modules, which can realize the detection of products of different sizes and front and back sides, and has strong practicability and diversity;

[0006] Although the above two patents have successfully realized the detection of the automotive interior structure, they face a significant problem in practical applications: the position of the automotive parts to be detected is fixed, which means that automatic flipping detection cannot be achieved during the detection process. Even if vision modules are respectively arranged above and below the detection parts in order to improve the comprehensiveness of detection through multi-angle observation, in actual operation, it is still difficult to avoid the existence of detection dead angles;

[0007] Specifically, due to the fixity of the component to be detected, some hidden parts or complex structures cannot be fully covered by the upper vision module or the lower vision module, resulting in these areas becoming detection blind spots or dead corners. If these detection dead corners hide potential quality problems or defects, it will affect the overall quality and safety of the automotive panel. Therefore, an on-line quality detection system for automotive panel components and its detection method are proposed. Summary of the Invention

[0016] The electric turntable is installed at the center of the upper surface of the detection platform, the carrier seat is installed on the top of the electric turntable, and the support seats are symmetrically installed on the upper surface of the carrier seat.

[0017] Further preferably, the carrier seat is located between the two sliding seats and between the two bottom linear modules.

[0018] Further preferably, four positioning seats are symmetrically installed on the upper surface of the detection platform, a position sensor is installed on the top of the positioning seat, and the position of the position sensor corresponds to the position of the carrier seat.

[0019] Further preferably, a frame is arranged outside the positioning component, the detection platform is fixedly connected to the inside of the frame, a machine shell is installed outside the frame, and an operation panel is installed on one side of the machine shell.

[0020] Further preferably, an upper linear module is installed on the inner top wall of the frame, a vision detection module is installed on the mover of the upper linear module, and the position of the vision detection module corresponds to the position of the carrier seat.

[0021] An on-line quality detection method for an automobile panel assembly includes the following steps:

[0022] Step 1: Place the automobile panel to be detected on the carrier seat, start the vision detection module, and collect images of the upper surface of the automobile panel;

[0023] Step 2: The bottom linear module drives the clamping seat to move, clamps the automobile panel by using the clamping cylinder and the clamping plate, lifts the automobile panel upward, and the articulated motor rotates;

[0024] Step 3: The articulated motor rotates counterclockwise and clockwise by 90 degrees respectively, collects images of the side of the automobile panel, the articulated motor rotates 180 degrees, puts down the automobile panel, and collects images of the back of the automobile panel;

[0028] Due to the above technical solutions, the embodiments of the present invention have the following advantages:

[0029] 1. In the present invention, a driving motor drives a lead screw. The lead screw drives a slider through a thread, and the slider moves upward along a guide rod. The slider drives a connecting arm, and thus the vehicle panel can be moved upward to reserve space for the flipping of the vehicle panel. A joint motor drives a connecting plate, and the connecting plate drives a clamping seat, and thus the clamping jaw structure can be rotated. The clamping jaw structure drives the vehicle panel, and at this time, the position of the vehicle panel can be adjusted. By rotating the joint motor at different angles, image acquisition can be performed on different surfaces of the vehicle panel. Then, with the cooperation of an electric turntable to drive the vehicle panel on its surface to rotate, omnidirectional acquisition of images of six surfaces of the vehicle panel can be achieved. Compared with the prior art, the present invention realizes the flipping and positioning of the vehicle panel to be detected. By flipping the vehicle panel to be detected, image data of the vehicle panel to be detected can be acquired omnidirectionally, thereby avoiding the situation of detection dead angles and improving the detection effect.

[0030] 2. In the present invention, a clamping cylinder pushes a clamping plate, and the clamping plate drives a contact plate. At this time, the vehicle panel can be clamped by the contact plate. By restricting the position of the vehicle panel, it is convenient to perform clamping and positioning on the vehicle panel. When the contact plate comes into contact with the vehicle panel, the spring will be compressed under the action of force, realizing the flexible contact of the contact plate with the vehicle panel; in this way, not only can the situation of damaging the vehicle panel due to excessive pressure be effectively avoided, further, in order to enhance the safety and protection during use, a silica gel pad is coated on the outer wall of the contact plate. This layer of silica gel pad not only has good anti-slip performance, ensuring that the contact plate can firmly fit with the vehicle panel under various operating conditions, is not easy to slip or shift, and thus ensures the stability during the image acquisition process.

Detailed Description of the Invention

[0042] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary in nature rather than restrictive.

[0043] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] As Figures 1 - 8 shown, an on-line quality detection system for automotive panel components according to an embodiment of the present invention includes a detection platform 11, on which a positioning component 101 is installed. The positioning component 101 is used to realize the flipping and positioning of the automotive panel to be detected. By flipping the automotive panel to be detected, the image data of the automotive panel to be detected can be collected in all directions, thereby avoiding the situation of detection dead angles and improving the detection effect;

[0045] The positioning component 101 includes two bottom linear modules 12, two sliding seats 13, a mounting seat 14, a driving motor 15, two guide rods 16, a slider 17, a lead screw 18, a connecting arm 19, a joint motor 20, a clamping seat 21, and a connecting disk 22;

[0046] The two bottom linear modules 12 are symmetrically mounted on the upper surface of the detection platform 11. The two sliding seats 13 are symmetrically mounted on the movers of the two bottom linear modules 12. The mounting seat 14 is fixedly connected to the upper surface of the sliding seat 13. The slider 17 is slidably connected to the inside of the mounting seat 14. By driving the sliding seat 13 with the two bottom linear modules 12, and the sliding seat 13 driving the mounting seat 14, the position of the clamping jaw mechanism can be adjusted, so that the clamping jaw approaches or moves away from the automotive panel to be detected. When the clamping jaw approaches the automotive panel to be detected, it is convenient to clamp the automotive panel to be detected. When the clamping jaw moves away from the automotive panel to be detected, the effect of image acquisition is ensured;

[0047] Both ends of the two guide rods 16 are symmetrically fixedly connected to the inner top wall and the inner bottom wall of the mounting seat 14. The top end of the lead screw 18 is fixedly connected to the output shaft of the driving motor 15. One end of the connecting arm 19 is fixedly connected to the slider 17. The driving motor 15 is mounted on the upper surface of the mounting seat 14. The bottom end of the lead screw 18 is rotatably connected to the inner bottom wall of the mounting seat 14. The slider 17 is threadedly connected to the outer side wall of the lead screw 18. The slider 17 is slidably connected to the outer side walls of the two guide rods 16. The position of the slider 17 can be limited by the guide rods 16. When the clamping jaw structure clamps the automotive panel, by driving the lead screw 18 with the driving motor 15, the lead screw 18 drives the slider 17 through the thread, and the slider 17 moves upward along the guide rods 16. The slider 17 drives the connecting arm 19, and then the automotive panel can be moved upward to reserve space for the flipping of the automotive panel;

[0048] The joint motor 20 is mounted on the other end of the connecting arm 19. The connecting disk 22 is fixedly connected to the output shaft of the joint motor 20. The clamping seat 21 is fixedly connected to one side of the connecting disk 22. By driving the connecting disk 22 with the joint motor 20, and the connecting disk 22 driving the clamping seat 21, the clamping jaw structure can be rotated, and the clamping jaw structure drives the automotive panel. At this time, the position of the automotive panel can be adjusted;

[0049] When the joint motor 20 rotates counterclockwise by 90 degrees, image acquisition is performed on one side of the automotive panel;

[0050] When the joint motor 20 rotates clockwise by 90 degrees, image acquisition is performed on the other side of the automotive panel;

[0051] When the joint motor 20 rotates counterclockwise by 180 degrees, image acquisition is performed on the bottom surface of the automotive panel.

[0052] In one embodiment, the positioning component 101 further includes two clamping cylinders 23, two clamping plates 24, four limiting rods 25, a spring 26 and a contact plate 27. Through the clamping seat 21, the clamping cylinders 23, the clamping plates 24, the limiting rods 25, the spring 26 and the contact plate 27, a jaw structure can be formed to realize the clamping and positioning of the automotive panel;

[0053] The spring is sleeved on the outer wall of the limiting rod, and its two ends respectively abut against the contact plate and the clamping plate. When the clamping cylinder pushes the clamping plate to drive the contact plate to contact the automotive panel, the automotive panel exerts a reaction force on the contact plate, causing the contact plate to compress the spring. The elastic deformation of the spring provides a buffering force, realizing the flexible contact of the contact plate with the automotive panel, which can not only ensure the stability of clamping, but also avoid damaging the automotive panel due to excessive pressure;

[0054] The two clamping cylinders 23 are symmetrically installed on the upper surface and the lower surface of the clamping seat 21. The two clamping plates 24 are symmetrically and slidably connected to the inside of the clamping seat 21. One end of the four limiting rods 25 is symmetrically and fixedly connected to the upper surface of the contact plate 27. The spring 26 is sleeved on the outer wall of the limiting rod 25. The cylinder shaft of the clamping cylinder 23 is fixedly connected to the clamping plate 24. By pushing the clamping plate 24 through the clamping cylinder 23, the clamping plate 24 drives the contact plate 27. At this time, the automotive panel can be clamped through the contact plate 27. By limiting the position of the automotive panel, it is convenient to clamp and position the automotive panel;

[0055] One end of the spring 26 abuts against the contact plate 27, and the other end of the spring 26 abuts against the clamping plate 24. When the contact plate 27 contacts the automotive panel, the spring 26 will be compressed under the action of force, realizing the flexible contact of the contact plate 27 with the automotive panel;

[0056] In this way, not only can the situation of clamping and damaging the automotive panel due to excessive pressure be effectively avoided. Further, in order to enhance the safety and protection during use, a silica gel pad is coated on the outer wall of the contact plate 27. This layer of silica gel pad not only has good anti-slip performance, ensuring that the contact plate 27 can firmly fit with the automotive panel under various operating conditions and is not easy to slip or shift; moreover, due to its softness and the characteristic of not causing wear to the surface, the silica gel pad can also effectively avoid any form of scratching or damage to the automotive panel, thus maintaining the original luster and beauty of the automotive panel.

[0057] In one embodiment, the positioning component 101 further includes an electric turntable 31, a bearing seat 32 and a support seat 33;

[0058] The electric turntable 31 is installed at the center of the upper surface of the detection platform 11. The bearing seat 32 is installed on the top of the electric turntable 31. The support seats 33 are symmetrically installed on the upper surface of the bearing seat 32. The bearing seat 32 is located between the two sliding seats 13 and between the two bottom linear modules 12. The bearing seat 32 is used to carry the automotive panel. The support seats 33 are in contact with the automotive panel, and a silica gel pad is provided on the surface of the support seats 33, thus avoiding the situation of scratching the automotive panel.

[0059] The electric turntable 31 drives the bearing seat 32 to rotate. The bearing seat 32 drives the support seats 33, and the support seats 33 drive the automotive panel on their surfaces to rotate, thereby adjusting the position of the automotive panel so as to collect the side surface of the automotive panel.

[0060] In one embodiment, four positioning seats 34 are symmetrically installed on the upper surface of the detection platform 11. A position sensor 35 is installed on the top of the positioning seat 34. The position of the position sensor 35 corresponds to the position of the bearing seat 32. The position sensor 35 can play a positioning role. When the bearing seat 32 rotates, the corresponding position sensor 35 detects the position of the bearing seat 32 to ensure that the bearing seat 32 can accurately rotate by ninety degrees to improve the detection accuracy of the automotive panel.

[0061] In one embodiment, a frame 36 is provided outside the positioning assembly 101. The detection platform 11 is fixedly connected to the inside of the frame 36. A casing 40 is installed outside the frame 36. An operation panel 39 is installed on one side of the casing 40. A processor is provided inside the operation panel 39 to process the collected images, including:

[0062] Preprocessing the image: Preprocessing the collected image, including denoising, enhancing contrast, adjusting brightness, etc., to improve the image quality;

[0063] Feature extraction: Using edge detection and contour extraction techniques to extract the key features of the automotive panel, including edges, corners, and textures;

[0064] Defect recognition: Analyzing the extracted features according to the preset detection criteria to identify the defects on the automotive panel, including scratches, dents, and bubbles. At the same time, using machine learning algorithms to classify and quantify the defects to improve the accuracy of recognition;

[0065] Position and size measurement: Measuring the position and size of the identified defects for subsequent positioning and repair.

[0066] In one embodiment, an upper linear module 37 is mounted on the inner top wall of the frame 36, and a vision detection module 38 is mounted on the mover of the upper linear module 37. The position of the vision detection module 38 corresponds to the position of the carrier 32. The vision detection module 38 is used to detect the image of the automotive panel. The position of the vision detection module 38 can be adjusted according to the actual position of the automotive panel by the upper linear module 37.

[0067] An on-line quality detection method for an automotive panel assembly includes the following steps:

[0068] Step 1: Place the automotive panel to be detected on the carrier, start the vision detection module, and collect images of the upper surface of the automotive panel. The vision detection module is equipped with a high-resolution camera and an advanced optical system to comprehensively and meticulously collect images of the upper surface of the automotive panel. This step is the basis of the detection process and provides high-quality image data for subsequent analysis;

[0069] Step 2: The bottom linear module drives the clamping seat to move, clamps the automotive panel by using the clamping cylinder and the clamping plate, lifts the automotive panel upward, and the articulated motor rotates;

[0070] Step 3: The articulated motor rotates counterclockwise and clockwise by 90 degrees respectively to collect images of the side of the automotive panel. The articulated motor rotates 180 degrees, puts down the automotive panel, and collects images of the back of the automotive panel. This series of actions ensures that every visible surface of the automotive panel can be comprehensively detected;

[0071] Step 4: The electric turntable drives the carrier to rotate by 90 degrees, and the positioning component repeats Step 2 and Step 3 to collect images of the side of the automotive panel. In this way, all side images of the automotive panel are completely collected;

[0072] Step 5: Extract the key features of the six surfaces of the automotive panel, and analyze the extracted features according to the preset detection criteria to identify defects on the automotive panel;

[0073] Step 6: Output the detection results in the form of a report, including the position, type, and size of the defects;

[0074] In Step 5, the steps for extracting the key features of the six surfaces of the automotive panel include the following steps:

[0075] Image acquisition: Use a high-precision vision detection module to collect images of the six surfaces (upper surface, lower surface, four sides) of the automotive panel, ensure that the ambient light for image acquisition is uniform, and avoid the influence of shadows or reflections on the image quality.

[0076] Image preprocessing: Preprocess the collected images, including denoising, enhancing contrast, adjusting brightness, etc., to improve the image quality. Use image segmentation technology to separate the automotive panel from the background for subsequent feature extraction;

[0077] Feature extraction: Use technologies such as edge detection, contour extraction, and texture analysis to extract the key features of the automotive panel. These features include the straightness of the edge, curvature, texture consistency, color uniformity, etc.

[0078] In step five, analyze the extracted features according to the preset detection criteria, including:

[0079] Set detection criteria: According to the manufacturing process and quality requirements of the automotive panel, set corresponding detection criteria. These criteria include the type of defects (such as scratches, dents, color differences), size, and location;

[0080] Feature matching and comparison: Compare the extracted features with the preset detection criteria to determine whether there are features that do not meet the standards. Use machine learning to automatically classify and identify the features to improve the accuracy and efficiency of detection;

[0081] Defect identification: According to the results of feature matching and comparison, identify the defects on the automotive panel, and measure the location and size of the identified defects for subsequent positioning and repair.

[0082] In step five, the specific methods for realizing the defect identification of the automotive panel include:

[0083] Algorithms based on image processing: Use image processing algorithms such as Hough transform and Canny edge detection to extract the edge and contour features of the automotive panel. By comparing the extracted features with the preset standards, identify defects such as scratches and dents;

[0084] Algorithms based on machine learning: Train a machine learning model to enable it to automatically identify the defects on the automotive panel. Use the trained model to predict and classify the collected images to identify the type and location of the defects;

[0085] Algorithms based on deep learning: Use deep learning technologies such as convolutional neural networks to extract features and classify the images of the automotive panel. Through a large amount of training data, enable the model to learn the normal and defective forms of the automotive panel, so as to achieve accurate identification of defects.

[0086] When the present invention is working: Place the automotive panel assembly to be detected on the surface of the support seat 33, and then drive the vision detection module 38 by the upper linear module 37. According to the actual position of the automotive panel, adjust the position of the vision detection module 38, and then collect images of the upper surface of the automotive panel assembly through the vision detection module 38;

[0087] Drive the sliding seat 13 by two bottom linear modules 12. The sliding seat 13 drives the mounting seat 14, and thus the position of the jaw mechanism can be adjusted to make the jaws close to the automotive panel to be detected, so that the two clamping plates 24 are respectively located above and below the automotive panel module. Push the clamping plate 24 by the clamping cylinder 23. The clamping plate 24 drives the contact plate 27. At this time, the automotive panel can be clamped by the contact plate 27. When the contact plate 27 contacts the automotive panel, the spring 26 will be compressed by the force, realizing the flexible contact of the contact plate 27 with the automotive panel. Then drive the lead screw 18 by the drive motor 15. The lead screw 18 drives the slider 17 through the thread, and the slider 17 moves upward along the guide rod 16. The slider 17 drives the connecting arm 19, and thus the automotive panel can be moved upward to reserve space for the flipping of the automotive panel;

[0088] Drive the connecting disk 22 by the articulated motor 20. The connecting disk 22 drives the clamping seat 21, and thus the jaw structure can be rotated. The jaw structure drives the automotive panel, and at this time the position of the automotive panel can be adjusted;

[0089] When the articulated motor 20 rotates counterclockwise by 90 degrees, the vision detection module 38 collects images of the first side of the automotive panel;

[0090] When the articulated motor 20 rotates clockwise by 90 degrees, the vision detection module 38 collects images of the second side of the automotive panel;

[0091] When the articulated motor 20 rotates counterclockwise by 180 degrees, the drive motor 15 reverses, and the automotive panel moves downward to the surface of the support seat 33. Drive the sliding seat 13 by two bottom linear modules 12. The sliding seat 13 drives the mounting seat 14 to move the jaw structure away from the automotive panel. At this time, the vision detection module 38 collects images of one bottom surface of the automotive panel;

[0092] Drive the bearing seat 32 to rotate by the electric turntable 31. The bearing seat 32 drives the support seat 33, and the support seat 33 drives the automotive panel on its surface to rotate. When the bearing seat 32 rotates, the corresponding position sensor 35 detects the position of the bearing seat 32 to ensure that the bearing seat 32 can accurately rotate by 90 degrees to improve the detection accuracy of the automotive panel;

[0093] Then, the two bottom linear modules 12 drive the sliding seat 13, and the sliding seat 13 drives the mounting seat 14 to bring the jaw structure closer to the automotive panel. At this time, the automotive panel can be clamped by the contact plate 27. Then, driven by the drive motor 15, the automotive panel moves upward. The articulated motor 20 drives the connecting plate 22, and the connecting plate 22 drives the clamping seat 21 to adjust the position of the automotive panel again;

[0094] When the articulated motor 20 rotates counterclockwise by 90 degrees, the vision detection module 38 collects images of the third side of the automotive panel;

[0095] When the articulated motor 20 rotates clockwise by 90 degrees, the vision detection module 38 collects images of the fourth side of the automotive panel;

[0096] After the image collection is completed, the processor inside the operation panel 39 processes the collected images. Through steps such as preprocessing the images, feature extraction, defect recognition, and position and size measurement, the defects on the automotive panel are identified, and then the detection results are output in the form of a report.

[0097] To ensure the normal operation and detection accuracy of the system, the system needs to be maintained and serviced regularly. Specifically, it includes: regularly cleaning the lens of the vision detection module to prevent dust and stains from affecting the image quality; checking the lubrication of moving parts such as clamping cylinders and electric turntables and replenishing lubricants in a timely manner; calibrating the position sensor to ensure its positioning accuracy; checking and updating the software system of the processor inside the operation panel to improve the accuracy and efficiency of defect recognition, etc.;

[0098] When detecting automotive panels with irregular shapes or special structures, the rotation angle of the articulated motor and the rotation angle of the electric turntable can be adjusted, combined with the flexible movement of the vision detection module, to collect image data as comprehensively as possible. At the same time, machine learning algorithms can be used to model and analyze special shapes and structures to improve the accuracy of defect recognition. When the vision detection module fails, the system should immediately issue an alarm and automatically switch to the standby detection mode, or stop the detection process and wait for the maintenance personnel to handle it. In addition, the system should have a fault diagnosis function to accurately judge the type and location of the fault for quick repair;

[0099] After the detection results are output in the form of a report, they can be used for quality control in the production process of automotive panels.
