[0002] With the rapid development of modern manufacturing, the automation and intelligence level of production lines are constantly improving, and the management and control of product quality has become one of the important factors in corporate competition. In the context of efficient production, how to quickly and accurately detect and identify defective products in the production process has become a key task for major manufacturing companies to improve production efficiency and reduce costs.

[0003] At present, there are many technologies and equipment for defective product detection on the market, mainly including machine vision-based detection systems, X-ray detection equipment, and other physical or chemical detection methods. These technologies usually detect products through sensors, cameras and other equipment, and analyze the collected images or data in combination with computer algorithms to determine whether the products have quality defects. Some companies have also deployed manual-assisted detection equipment on the production line, which uses cameras to capture product images and then manually determines and marks defective products.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0030] like Fig.13As shown, the present invention provides a defective product data acquisition system, including an image acquisition module 1, a data processing module 2, an image display module 3 and an industrial control integrated machine 4. The image acquisition module 1, the image display module 3 and the data processing module 2 are all electrically connected to the industrial control integrated machine 4 to achieve data interaction and system collaboration between the modules.

[0031] The industrial control integrated machine 4 is internally integrated with a defective item marking module 41, which is used to mark defective items found during product testing. The defective items of a product include at least two items, which may specifically include but are not limited to surface scratches, stains, dimensional deviations and other defective phenomena. The industrial control integrated machine 4 is also used to control the movement of the image acquisition module 1 to adjust the shooting position.

[0032] In this system, the image acquisition module 1 is used to acquire images of products passing through the production line, and transmit the acquired image information to the industrial control integrated machine 4 through the communication interface. After receiving the image information, the industrial control integrated machine 4 controls the image display module 3 to display the image. The inspection personnel view the image of the product through the image display module 3 to perform appearance inspection and quality inspection on the product.

[0033] like Fig.14 As shown, Fig.14 This is an interface diagram of the defective item marking module 41 of the industrial control integrated machine 4. When the inspector finds a defective item in the product in the image, the defective item marking module 41 on the industrial control integrated machine 4 is used to mark the specific defective location and type. The defective item marking module 41 provides standardized marking options to ensure that all inspectors record the defective items consistently and clearly. After completing the marking, the industrial control integrated machine 4 transmits the product data containing the marking information to the data processing module 2.

[0034] After receiving the product data, the data processing module 2 analyzes and processes the data and automatically records the relevant information of the defective items. The data processing module 2 can summarize and classify the test data of multiple test points to provide strong data support for subsequent quality control and improvement. In addition, the data processing module 2 can also generate a test report for management personnel to conduct quality analysis and decision-making reference.

[0035] Specifically, the image acquisition module 1 includes a camera 11, a zoom lens 12 and a light source 13. The camera 11 is used to capture images of products, and the zoom lens 12 adjusts the focal length to meet the shooting requirements of products of different sizes or features. The camera 11 and the zoom lens 12 are detachably connected, which is convenient for replacement or maintenance according to actual needs. The light source 13 is used to provide uniform lighting for the shooting process, ensuring that the clarity and details of the image are consistent under different ambient light conditions, so as to improve the detection accuracy.

[0036] The image display module 3 is specifically a high-resolution display, which is used to display the product image acquired by the image acquisition module 1. The display can clearly present the appearance details of the product, helping the inspector to quickly identify possible defective items. The inspector can observe carefully through the display and evaluate the quality of the product in combination with the system prompts.

[0037] Wherein, the data processing module 2 includes: The data storage module is used to store historical test data, including product defect information, test locations, and test results. The stored data provides a basis for subsequent analysis and prediction, ensuring that the system can use existing data to make intelligent decisions.

[0038] The data analysis module is configured to analyze the stored historical test data. By analyzing the test records of multiple products, the module can identify the high-frequency areas and key test locations where the most defective items appear during the test process. The high-frequency areas refer to the areas with the most manually selected shooting positions, and the key test locations refer to the locations where the most defective items appear.

[0039] The position prediction module is configured to predict the priority shooting position of the current product; based on product characteristics and historical inspection data, it identifies high-risk areas where defects may occur, ensuring that inspectors can prioritize checking these key areas, thereby improving the accuracy and efficiency of inspections.

[0040] The drive control module is configured to receive the priority shooting position data output by the position prediction module, and transmit the corresponding position signal to the industrial control integrated machine 4, and control the shooting position of the image acquisition module 1 through the industrial control integrated machine 4. The image acquisition module 1 is driven to automatically adjust so that it is aligned with the predicted high-risk area, thereby achieving accurate shooting and detection.

[0041] In this embodiment, the data processing module 2 also includes: The classification management module is configured to classify the test data by test time and defective items; specifically, classification by test time and defective items. The classification management module can archive data by time (such as day, shift, or specific time period), and can also classify and store by defective items (such as surface scratches, stains, dimensional deviation, etc.). The purpose of this module is to facilitate managers to view and analyze test data in different dimensions, quickly find records of specific time periods or defective types, and thus improve the efficiency and convenience of data management.

[0042] The alarm module is configured to set and manage alarm thresholds related to defective items, including continuous single-item defect quantity alarms and single-item cumulative defect quantity alarms; when a defective item appears multiple times in a row during the production process, or when the cumulative number of times within a shift reaches a preset value, the alarm setting module will automatically trigger an alarm to alert production managers. The main purpose of this module is to ensure that managers can monitor abnormal conditions in the production line in real time and take timely measures to prevent the large-scale production of defective products.

[0043] The data recording module is configured to record each test data, including time, test personnel, defective item mark and product number. It allows managers to quickly find and trace back past test records based on time, shift or product number, helping companies trace the source of defective products, conduct responsibility tracing and quality improvement. Through the traceability function, companies can effectively improve the transparency of the production process and the level of quality management.

[0044] The industrial control integrated machine 4 is not only used to control the coordinated work of each module, but also has a human-computer interaction function. The inspector operates the defective item marking module 41 through the interface of the industrial control integrated machine 4 to mark the defective parts in the product image. After marking, the industrial control integrated machine 4 transmits the image containing the marking information and other related data to the data processing module 2. The data processing module 2 further processes and stores these data in order to generate a quality report or for subsequent quality improvement analysis.

[0045] The industrial control integrated machine 4 of the defective product data collection system of the present invention integrates a defective item marking module 41, allowing inspectors to electronically mark the defective location and type through a standardized operating interface when a defective item is found. The marking method is standardized and unified, avoiding the problem of information confusion caused by inconsistent recording methods of different operators. At the same time, the marked data can be automatically stored and managed, avoiding data loss that is prone to occur in paper records. The module receives and processes product images and defective item marking data transmitted by the industrial control integrated machine 4, automatically records and classifies and stores relevant information, and supports subsequent quality control and analysis. Compared with paper records, the data processing module 2 provides more efficient and accurate data management and analysis functions, solves the inconvenience of traditional recording methods in management and analysis, and significantly improves quality control and improvement efficiency in the production process.

[0046] In addition, if Figures 1 to 12 As shown, another embodiment of the present invention further provides a defective product data acquisition device, which includes the above-mentioned defective product data acquisition system and a linear drive mechanism 5 to achieve position adjustment of the image acquisition module 1, so as to adapt to the needs of products of different sizes or different detection positions.

[0047] The linear drive mechanism 5 is connected to the image acquisition module 1 and is used to control the image acquisition module 1 to move and position accurately along the linear direction. In existing automated workstations, the products produced are usually transported by the conveying mechanism 9 and inspected by the image acquisition module 1. However, due to differences in product size or specific locations to be inspected, it is often necessary to adjust the acquisition position of the image acquisition module 1 to ensure that the desired inspection location can be accurately captured.

[0048] In order to solve this problem, a linear drive mechanism 5 is provided in the device in this embodiment. Through the linear drive mechanism 5, the linear motion of the image acquisition module 1 can be realized, so as to adjust its acquisition position. The linear drive mechanism 5 can flexibly control the movement of the image acquisition module 1 according to the actual size of the product and the detection requirements, so that it can accurately align and capture the position to be detected. This structural design not only improves the flexibility and accuracy of detection, but also reduces the error and time consumption caused by manual position adjustment.

[0049] In addition, the device also includes a profile frame 6, which provides stable support and protection for the overall structure of the device. The lower surface of the top wall 62 of the profile frame 6 is connected to the linear drive mechanism 5 to ensure that the linear drive mechanism 5 has sufficient stability and support during movement. In order to facilitate maintenance and overhaul, an inspection door 61 is also provided on the profile frame 6. The design of the inspection door 61 allows operators to easily inspect, maintain and repair the internal drive mechanism and acquisition module, ensuring the normal operation of the device and extending its service life.

[0050] Specifically, the linear drive mechanism 5 includes two mounting seats 51, two guide rails 52, a lead screw 53, a first motor 54 and a moving beam 55. Specifically, the two mounting seats 51 are fixedly connected to the lower surface of the top wall 62 of the profile frame 6 to provide a stable support structure. The lead screw 53 is horizontally installed and rotatably connected between the two mounting seats 51, and its two ends are supported by bearings to ensure that the lead screw 53 remains stable during rotation.

[0051] The first motor 54 is mounted on a mounting seat 51, and its output end is connected to one end of the lead screw 53 through a coupling, so as to drive the rotation of the lead screw 53. The first motor 54 is connected to the industrial control integrated computer 4. When the position of the image acquisition module 1 needs to be adjusted, the industrial control integrated computer 4 will issue a command to control the first motor 54 to start. As the first motor 54 rotates, the lead screw 53 also rotates. Since the lead screw 53 is threadedly connected to the moving beam 55, the rotation of the lead screw 53 will push the moving beam 55 to slide linearly along the guide rail 52.

[0052] The two guide rails 52 are arranged in parallel and fixedly installed between the two mounting seats 51, forming a linear motion guide structure. Both ends of the moving beam 55 are slidably connected to the guide rails 52, so that the moving beam 55 can move smoothly and accurately on the guide rails 52. It is ensured that the image acquisition module 1 can perform a smooth linear motion along a predetermined path without deviation or tilt.

[0053] The image acquisition module 1 is fixedly mounted on the lower side of the moving beam 55. As the moving beam 55 slides between the guide rails 52, the acquisition position of the image acquisition module 1 is precisely adjusted accordingly. This structure allows the image acquisition module 1 to flexibly adjust its position according to the product size or detection requirements, ensuring accurate detection of products of different positions or sizes.

[0054] Through the design of the linear drive mechanism 5, the present invention can effectively control the position of the image acquisition module 1, solving the problem of frequent manual adjustment required due to changes in product size or detection position in traditional equipment. With the intelligent control of the industrial control all-in-one machine 4, the adjustment process of the image acquisition module 1 is not only more accurate, but also greatly improves the automation level and detection efficiency of the production line. At the same time, the structural design of the linear drive mechanism 5 also takes into account the durability and maintenance convenience of the equipment, ensuring the long-term and stable operation of the device.

[0055] In this embodiment, the data processing module 2 includes: Data storage module: This module is used to store previous inspection data, including the position of the image acquisition module 1 during each inspection process, the corresponding product image and its defective item information.

[0056] Data analysis module: This module analyzes the stored historical data and extracts the key shooting positions manually selected during the inspection of different products. By statistics and analysis of these data, the high-frequency areas and key positions of product inspection are identified.

[0057] Position prediction module: Based on the output of the data analysis module, the position prediction module can predict the best shooting position for the current product. This module uses machine learning or rule algorithms to automatically determine where the image acquisition module 1 should be adjusted to shoot in this inspection based on the inspection data of similar products in the past.

[0058] Drive control module: used to receive the best shooting position data output by the position prediction module, and transmit the corresponding position signal to the industrial control integrated machine 4, and send a control signal to the linear drive mechanism 5 through the industrial control integrated machine 4. The linear drive mechanism 5 adjusts the position of the image acquisition module 1 according to the signal to ensure that it is accurately positioned at the position required for detection.

[0059] During each inspection process, the data storage module will record the position of the image acquisition module 1, the collected images and their corresponding inspection results. These data are continuously accumulated to form a historical database. The data analysis module analyzes the data in the historical database regularly or when needed. The focus of the analysis is to find the most frequently selected shooting positions in the inspection, especially those bad item positions that have been marked as key areas many times. By analyzing these data, the system can identify which positions are high-risk areas in the inspection. In a new inspection task, the position prediction module will use the rules obtained by the analysis to predict the best shooting position of the image acquisition module 1 according to the characteristics of the current product or the inspection requirements, and give priority to the best shooting position, that is, the priority shooting position. This prediction not only refers to the current state of the product, but also comprehensively considers the inspection data of similar products in the past to ensure the accuracy of the prediction results. Once the position prediction module generates specific shooting position data, the drive control module converts it into a control signal and transmits it to the industrial control integrated machine 4, and sends a control signal to the linear drive mechanism 5 through the industrial control integrated machine 4. And the position of the image acquisition module 1 is automatically adjusted through the linear drive mechanism 5. In this way, the image acquisition module 1 can accurately align with the key position required for inspection without manual intervention.

[0060] Specifically, it also includes an image acquisition control mechanism 7 disposed at the lower side of the moving beam 55 , and the image acquisition control mechanism 7 is connected to the image acquisition module 1 .

[0061] The image acquisition control mechanism 7 includes a connecting arm 71, a support plate 72, a cylinder 73, a connecting plate 74, two driving arms 75, two driving members 76, two limiting assemblies 77 and two mounting plates 78. The lower surface of the moving beam 55 is fixedly connected to the support plate 72 through the connecting arm 71, the connecting arm 71 is composed of two bending plates, the cylinder 73 is fixedly installed between the two bending plates, the output end of the cylinder 73 is connected to the connecting plate 74, the connecting plate 74 is connected to the two driving arms 75, the ends of the two driving arms 75 away from the connecting plate 74 are fixedly connected to the two driving members 76, the driving members 76 are provided with driving grooves 761, and the two limiting assemblies 77 are installed on the upper surface of the support plate 72 for limiting the movement of the driving arms 75. The two mounting plates 78 are rotatably connected to the support plate 72 via the rotating shaft 781. The two mounting plates 78 are provided with driving rods 782. The support plate 72 is provided with two arc-shaped notches 721, and the center of the arc-shaped notches 721 is on the straight line where the axis of the rotating shaft 781 is located. The two driving rods 782 pass through the two arc-shaped notches 721 and extend into the driving groove 761 respectively.

[0062] In this embodiment, if Figure 6 , Figure 7 and Figure 8As shown, the number of image acquisition modules 1 is four, and two image acquisition modules 1 are arranged on each mounting plate 78. The four image acquisition modules 1 are arranged in a quadrilateral. In actual operation, each image acquisition module 1 is used to shoot different positions / details of the product, ensuring that the acquisition of the product image is more accurate. However, for individual products, the image acquisition modules 1 arranged in a quadrilateral may not completely correspond to the product position to be acquired. Therefore, an image acquisition control mechanism 7 is designed in this embodiment, wherein the cylinder 73 is connected to the industrial control integrated machine 4 and is controlled by the industrial control integrated machine 4. When the position of the image acquisition module 1 needs to be adjusted, the industrial control integrated machine 4 controls the action of the cylinder 73. The output end of the cylinder 73 pushes the connecting plate 74 to move, thereby driving the two driving arms 75 connected thereto. One end of the driving arm 75 away from the connecting plate 74 is fixedly connected to the driving member 76, and the driving member 76 is provided with a driving groove 761. The movement of the driving arm 75 acts on the driving rod 782 through the driving groove 761, so that the driving rod 782 moves along the arc-shaped notch 721 on the support plate 72. Since the center of the arc-shaped notch 721 is located on the axis of the rotating shaft 781, the movement of the driving rod 782 will cause the mounting plate 78 to rotate around the rotating shaft 781. When the four image acquisition modules 1 are arranged in a straight line, the maximum adjustment stroke is reached.

[0063] The rotation of the mounting plate 78 directly drives the image acquisition module 1 on the lower side to adjust its position. Through this mechanism design, the image acquisition module 1 can be adjusted in multiple angles and directions according to the actual situation of the product to ensure that the viewing angle of each image acquisition module 1 can be accurately aligned with the area to be inspected of the product. This design is particularly suitable for products that require high-precision and multi-angle inspection, so that the image acquisition module 1 can more flexibly adapt to the complex shapes and inspection requirements of different products.

[0064] After the test is completed, the industrial control integrated machine 4 can also control the output end of the cylinder 73 to extend, and reset the mounting plate 78 to the initial position according to the opposite movement path of the adjustment. This reset function ensures that the image acquisition module 1 can return to the predetermined position after the test is completed, ensuring that the device can quickly return to the standard state when it is operated next time.

[0065] The design of the limit assembly 77 further ensures the reliability of the image acquisition control mechanism 7. The limit assembly 77 includes two support rods 771 and a roller shaft 772 rotatably mounted between the support rods 771. The driving arm 75 passes through the limit space, so that the roller shaft 772 effectively limits the motion range of the driving arm 75, preventing the driving arm 75 from exceeding the predetermined trajectory, thereby ensuring the motion accuracy and safety of the system.

[0066] By setting up multiple image acquisition modules 1, the product can be fully photographed from different angles. This multi-angle acquisition method ensures that all parts of the product can be clearly captured, avoiding blind spots or missed inspections that may occur from a single perspective. Each image acquisition module 1 is responsible for different perspectives and positions, which helps to obtain the complete image and detailed features of the product, thereby improving the accuracy of the overall image acquisition. In actual operation, some products may have complex shapes or irregular surfaces, and a single image acquisition module 1 may cause some details of the image to be distorted or blocked due to perspective problems. Through the collaborative work of multiple image acquisition modules 1, this distortion phenomenon can be effectively reduced, and the complementary acquisition between each module ensures that the final generated image is more accurate and clear. Multiple image acquisition modules 1 work simultaneously, and different parts of the product can be photographed with high resolution. Compared with a single module covering the entire product area, multiple modules with clear division of labor can collect more detailed information in the same or shorter time, and capture tiny defects on the surface of the product with higher resolution, thereby improving the clarity of the image.

[0067] In this embodiment, the data processing module 2 includes: Bad item location screening module: used to analyze and screen the high-incidence locations of bad items in previous test data. This module collects statistics on historical test data, identifies the locations where bad items appeared in past tests, and sorts them according to the frequency of occurrence of bad items.

[0068] Priority detection module: Based on the data provided by the defective item location screening module, the priority detection module controls the corresponding image acquisition module 1 to be turned on first. Fig.14 As shown, in the actual detection process, the system first starts the image acquisition module 1 corresponding to the high-incidence position of the defective items, and collects relevant images for the detection personnel to view.

[0069] Step-by-step inspection control module: If the inspector does not mark any defective items when viewing the first batch of images, the current image acquisition module 1 is turned off, and the image acquisition modules 1 at the locations with the second and third most defective items are turned on in turn, and so on.

[0070] The defective item location screening module first screens out the locations where defective items appear most frequently during the detection process from historical data. These locations are sorted according to their frequency of occurrence to form a priority list. When a new round of detection is carried out, the priority detection module first turns on the image acquisition module 1 corresponding to the location where defective items are most likely to occur, according to the priority list. This image acquisition module 1 starts working, collects images of the relevant locations, and transmits the images to the monitoring interface of the inspector for viewing. If the inspector does not mark the location as a defective item after initially viewing the image, the system will automatically enter the step-by-step detection process. The step-by-step detection control module will turn off the current image acquisition module 1, and turn on the image acquisition module 1 corresponding to the next location in the priority list, and continue to collect images for inspection by the inspector. This cycle continues until all high-priority locations have been inspected or the inspector marks a defective item.

[0071] By giving priority to opening the image acquisition module 1 at the location where the defective items are most likely to occur, the system enables the inspectors to first view the images of the areas where the problems are most likely to occur. This method allows the inspectors to focus on the key areas more quickly, reduce unnecessary image browsing, and improve the inspection efficiency. The inspectors do not need to view the images of all the image acquisition modules 1 at the same time, but can check each high-priority area step by step and in sequence. This design reduces the workload of the inspectors and reduces their time and energy consumption in tedious image switching and inspection. By opening the image acquisition modules 1 in sequence according to the priority order of the frequency of defective items, the inspectors only need to focus on the images of the key areas without wasting time viewing all the images of the entire product. This method not only shortens the inspection time, but also enables the inspectors to complete the task more efficiently. By focusing on the key positions, the inspectors can focus more on the inspection of these areas, thereby reducing the possibility of missed inspections or false inspections due to information overload or distraction. The step-by-step inspection method makes the inspection more orderly and further improves the accuracy of the inspection.

[0072] Specifically, although the position of the image acquisition module 1 can be adjusted to obtain as accurate and clear product images as possible, in some cases, especially when shooting at the edge of the product, the image may still be unclear. In order to further improve the clarity and accuracy of the product image acquisition, the defective product data acquisition device of this embodiment also includes an assembly structure 8 that can be spliced ​​with the mounting plate 78 to optimize the image acquisition effect.

[0073] The assembly structure 8 includes a mounting body 81, a card block 82, a spring 83, a pull rope 84, a pressing member 85 and a pressing block 86. The assembly structure 8 is designed to provide a flexible splicing mechanism to ensure that the image acquisition module 1 can maintain an optimal position under various operating conditions, thereby obtaining a clearer image. Two mounting cavities are provided inside the mounting body 81: a first mounting cavity 811 and a second mounting cavity 812. The card block 82 is slidably installed in the first mounting cavity 811, and can be extended from the first mounting cavity 811 under the action of the spring 83. The spring 83 provides elastic force for the card block 82 to ensure that the card block 82 can be smoothly extended and form a reliable splicing with the mounting plate 78. One end of the card block 82 extending from the first mounting cavity 811 has an arc surface 821, and a channel 813 for the pull rope 84 to slide is also provided inside the mounting body 81. One end of the pull rope 84 is connected to the card block 82, and the other end passes through the channel 813 and is connected to the pressing block 86. The pressing block 86 is slidably installed in the second installation cavity 812 and is fixedly connected to the pressing rod 851 on the lower surface of the pressing member 85. When the pressing member 85 is pressed, the pressing rod 851 pushes the pressing block 86 to slide, and then pulls the clamping block 82 back into the first installation cavity 811 through the pull rope 84. This design allows the clamping block 82 to be easily extended or retracted when needed, thereby flexibly realizing splicing or separation with the mounting plate 78.

[0074] The first side 783 and the second side 784 of the mounting plate 78 are respectively provided with mounting rods 785, and there is a gap between the mounting rod 785 and the mounting plate 78 for the block 82 to extend into, so as to allow the block 82 to extend into. In addition, a guide slope 7851 is provided on the side of the mounting rod 785 away from the mounting plate 78, so as to facilitate the smooth progress of the installation operation. During the operation, the end of the mounting body 81 with the block 82 is aligned with the gap between the mounting plate 78 and the support plate 72 and inserted, so that the arc surface 821 of the block 82 contacts the guide slope 7851 of the mounting rod 785. As the mounting body 81 is advanced, the block 82 is forced to be retracted into the first mounting cavity 811 under the action of the guide slope 7851, and the spring 83 is compressed and stored in the process. When the block 82 passes over the mounting rod 785 , the elastic force of the spring 83 causes the block 82 to extend rapidly and enter the gap between the mounting rod 785 and the mounting plate 78 , thereby firmly fixing the mounting body 81 on the mounting plate 78 .

[0075] At this time, the upper surface of the mounting body 81 contacts the lower surface of the support plate 72, achieving a reliable connection between the two components. The lower surface of the mounting body 81 carries the image acquisition module 1. Through this structural design, the stability and accuracy of the image acquisition module 1 can be significantly improved during product inspection.

[0076] The design of this assembly structure effectively solves the problem of limited shooting points due to the fixed position of the image acquisition module in traditional devices. By flexibly installing and removing the image acquisition module 1 on the mounting plate 78, more shooting points and a wider shooting area can be covered, ensuring that all key parts of the product can be captured completely and clearly. In addition, the assembly method of the mounting body 81 is simple and quick, which is convenient for operators to adjust according to actual needs, thereby further improving the accuracy and clarity of image acquisition.

[0077] When the assembly structure 8 needs to be disassembled, the operation process is simple and quick, and only needs to follow the following steps: First, hold the end of the mounting body 81 away from the mounting plate 78 to ensure a firm grip. Then, press the pressing member 85 downward. During the pressing of the pressing member 85, the pressing rod 851 will move downward synchronously, driving the pressing block 86 to move downward in the second mounting cavity 812. Since one end of the pull rope 84 is connected to the pressing block 86, the downward movement of the pressing block 86 will pull the card block 82 backward to the inside of the first mounting cavity 811 through the pull rope 84.

[0078] When the block 82 is completely retracted into the first mounting cavity 811, it will no longer contact the gap between the mounting rod 785 and the mounting plate 78, and the connection between the mounting body 81 and the mounting plate 78 is released. The operator can easily remove the entire assembly structure 8 without using additional tools, which facilitates the operator's daily maintenance work and ensures that the image acquisition module can be replaced or reconfigured quickly when it is needed, thereby improving the operating efficiency and flexibility of the equipment.

[0079] It also includes a conveying mechanism 9 for product transmission. The conveying mechanism 9 is designed to accurately convey the product to the bottom of the image acquisition module 1, so as to facilitate efficient and accurate image acquisition and defective product detection.

[0080] Specifically, the conveying mechanism 9 includes two side plates 91, a conveying belt 92, a driving roller shaft 93, a driven roller shaft 94, a support plate 95 and a second motor 96. The two side plates 91 are fixedly connected to the two sides of the profile frame 6, respectively, providing a solid support structure for the entire conveying mechanism. The driving roller shaft 93 and the driven roller shaft 94 are rotatably installed between the two side plates 91, respectively, to form a support and transmission structure for the conveying belt 92.

[0081] The conveyor belt 92 passes over the driving roller 93 and the driven roller 94, and realizes continuous product conveying through the rotation of the two rollers. The support plate 95 is fixedly installed between the side plates 91 and is located below the conveyor belt 92, providing necessary support for the conveyor belt 92, ensuring that the conveyor belt remains stable and has sufficient carrying capacity when carrying products.

[0082] The output end of the second motor 96 is connected to one end of the active roller shaft 93, and the conveyor belt 92 is driven to run by driving the active roller shaft 93 to rotate. The second motor 96 is connected to the industrial control integrated computer 4 and is controlled by the industrial control integrated computer 4. When the industrial control integrated computer 4 sends a start signal, the second motor 96 starts and drives the active roller shaft 93 to rotate, thereby driving the conveyor belt 92 to move. As the conveyor belt 92 moves, the product is continuously conveyed to the bottom of the image acquisition module 1 for detection.

[0083] The driven roller 94 rotates with the conveyor belt 92 to ensure the tension and smooth transmission of the conveyor belt 92. The support plate 95 provides a stable support force under the conveyor belt 92 to prevent the conveyor belt from sagging or deforming when carrying products, ensuring that the products remain stable during transportation, so that the image acquisition module 1 can perform accurate image acquisition.

[0084] It is particularly important to note that the conveying direction of the conveyor belt 92 for the product is perpendicular to the driving direction of the linear drive mechanism 5 for the image acquisition module 1. In actual use, the position of the image acquisition module 1 can be adjusted by the linear drive mechanism 5 according to the image of the specific position of the product to be acquired. When the image acquisition modules 1 are arranged in a straight line, the conveying direction of the conveyor belt 92 for the product is also perpendicular to the arrangement direction of the image acquisition modules 1. Such a design ensures that the product can pass through each image acquisition module 1 along a fixed trajectory, thereby achieving all-round image acquisition.

[0085] By designing the conveying direction of the conveyor belt 92 to be perpendicular to the driving direction of the linear drive mechanism 5, the image acquisition module 1 can move in a direction perpendicular to the product conveying path. This design allows the operator to adjust the position of the image acquisition module 1 as needed, so as to accurately capture images of different parts of the product. Regardless of how the position of the product changes, the image acquisition module 1 can be positioned to the area that needs to be inspected, thereby improving the flexibility of detection. When the image acquisition module 1 is in a "one" shape arrangement, the conveying direction of the conveyor belt 92 remains perpendicular to the arrangement direction of the image acquisition module 1. This arrangement ensures that the product can pass through each image acquisition module 1 along a fixed trajectory and be photographed from different angles, thereby achieving all-round image acquisition of the product. This is particularly important for detecting products with complex shapes or multiple surface features to ensure that no key details are missed.

[0086] In addition, another embodiment of the present invention further provides a method for collecting defective product data. The implementation of the method depends on the above-mentioned defective product data collection system, including: The image of the product passing through the production line is collected by the image collection module 1. The collected image information is transmitted to the industrial control integrated machine 4 through the communication interface.

[0087] After receiving the image information, the industrial control integrated machine 4 displays the product image on the screen by controlling the image display module 3. The image display module 3 can be a high-definition display to ensure that the inspector can observe every part of the product clearly and in detail. In this step, the inspector views the displayed product image to judge the product appearance and quality.

[0088] When the inspector finds a defective item in the product in the image, the specific location and type of the defective item are marked through the defective item marking module 41 in the industrial control integrated machine 4. The defective item marking module 41 provides standardized marking options, and the inspector can select a preset marking type, such as scratches, stains or size deviations, and accurately mark the location of the defective item on the image. The marking time, inspector information and other relevant data are recorded at the same time to ensure the accuracy and consistency of the record.

[0089] After completing the marking of defective items, the industrial control integrated machine 4 transmits the product data containing the marking information to the data processing module 2. The data processing module 2 analyzes the received product data, including automatically identifying and classifying different types of defective items, summarizing the defective item data of each detection point, and storing it in the database. The data processing module 2 can generate statistical reports based on historical data and current detection data, such as the frequency of occurrence of defective items, the distribution of defective item types, etc., for management personnel to conduct in-depth quality analysis.

[0090] By collecting images of products passing through the production line through the image acquisition module 1 and displaying them instantly on the industrial control integrated machine 4, the inspectors can quickly and accurately conduct appearance inspection and quality inspection of the products. Compared with the traditional method that relies on manual paper records, this method significantly reduces the number of manual operation steps, reduces the probability of missed inspections and false inspections, and improves the overall inspection efficiency and accuracy.

[0091] The bad item marking module 41 provides standardized marking options to ensure that all inspectors record the bad items consistently and clearly. This standardized processing eliminates the problem of inconsistent marking due to personal differences in manual records, reduces the risk of unclear information and misunderstanding, and ensures the standardization and consistency of test data. The test data is summarized and classified and stored through the data processing module 2, and the test report can be automatically generated. This not only solves the problem of difficult management of paper records, but also provides management with convenient data access and analysis tools to support more in-depth quality analysis and improvement.

[0092] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
