Description

Technical Field

[0001] This utility model relates to the technical field of visual automatic line control, and in particular to a visual automatic line control device. Background Technology

[0002] The development of vision-based automated line control devices is an inevitable trend in the transition of industrial automation to the intelligent stage. In traditional manufacturing, manual operation is insufficient to meet the demands of large-scale, high-intensity production, while early automated equipment lacked environmental perception capabilities and was not flexible enough in responding to dynamic changes. With breakthroughs in machine vision, sensor, and artificial intelligence technologies, by integrating intelligent cameras, programmable logic controllers, and image processing algorithms, this system can identify workpiece positions in real time, detect quality deviations, and drive actuators to achieve precise control.

[0003] Traditional vision-based automated line control systems typically employ fixed-mount inspection cameras positioned at specific locations on the automated transport platform, such as the edge or center, to perform basic inspection functions by capturing static images. While fixed camera setups can provide stable inspection under ideal conditions, their main problem lies in insufficient coverage due to rigid viewing angles: when items move or shift positions on the automated transport platform, fixed cameras cannot dynamically adjust their viewing angles, easily leading to blind spots or missed inspections. For example, on high-speed production lines, variations in item size or shape may cause fixed cameras to miss edge details, resulting in misjudgments or quality defects, impacting overall production efficiency and reliability.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a visual automatic line control device is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a visual automatic line control device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a visual automatic line control device, comprising: an automatic transport platform, two U-shaped rods disposed on the top of the automatic transport platform, and two sets of detection components disposed between the two U-shaped rods;

[0007] Both U-shaped rods are fixedly connected to the top of the automated transport platform, and a second detection camera is fixedly connected to one side of one of the U-shaped rods;

[0008] The detection component includes: two slide rails, which are fixedly positioned between two U-shaped rods, and a first detection camera is slidably connected to the two slide rails;

[0009] The top of the two U-shaped rods is provided with a drive module, which includes a drive motor, a transmission mechanism, a control unit, an image processing module, and a detection sensor. The drive motor is connected to the first detection camera through the transmission mechanism to drive the first detection camera to move back and forth along the slide rail.

[0010] In a preferred embodiment of this utility model, the slide rail is a linear guide rail.

[0011] In a preferred embodiment of this invention, the first detection camera and the second detection camera are CCD vision detectors.

[0012] In a preferred embodiment of this invention, the control unit is configured to process image data acquired by the first detection camera and the second detection camera.

[0013] In a preferred embodiment of this utility model, two supports are fixedly connected to the bottom of the automated transport platform.

[0014] In a preferred embodiment of this invention, the field of view center of the second detection camera coincides with the geometric center of the automated transport platform.

[0015] In a preferred embodiment of this invention, the movement paths of the two first detection cameras are symmetrically distributed on the left and right sides of the field of view of the second detection camera.

[0016] In a preferred embodiment of this invention, the two first detection cameras move in opposite directions, and the two first detection cameras correspond to the left and right sides of the automated transport platform, respectively.

[0017] In a preferred embodiment of this invention, the first and second detection cameras are set to low aperture and automatic gain mode when acquiring images.

[0018] In a preferred embodiment of this invention, the image processing module is configured to perform real-time analysis on the images acquired by the first detection camera and the second detection camera.

[0019] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0020] (1) This utility model provides a visual automatic line control device. By setting a slide rail between two U-shaped rods, the first detection camera can move back and forth along the slide rail, controlled by the drive motor and transmission mechanism in the drive module. This allows the camera to adjust its position to adapt to different detection needs. Moving the camera can cover the dynamic area of ​​the automatic transport platform and avoid the limitations of a fixed viewing angle. The direct effect is to improve the adaptability of the detection range and ensure comprehensive monitoring of transported items. In contrast, in the prior art, cameras are mostly fixed and easy to produce blind spots or missed detections. This not only enhances the detection accuracy but also reduces the risk of misjudgment caused by changes in the position of the items, thereby improving the reliability of the overall automated line.

[0021] (2) This utility model provides a visual automatic line control device. The device has a fixed second detection camera located at the center of the automatic transport platform, while two first detection cameras are symmetrically distributed on the left and right sides and move in opposite directions. By combining the fixed and moving cameras, synchronous detection of the center and edge areas of the platform is achieved. The fixed camera at the center ensures the stability of the reference field of view, while the moving camera makes up for the insufficient edge coverage, thereby forming a detection network without blind spots and improving the integrity of image acquisition. Compared with the existing technology, which often relies on a single camera or asymmetrical arrangement, it is easy to cause uneven detection. The collaborative layout not only reduces the need for manual intervention, but also enhances the robustness of the system in complex environments, such as dealing with changes in light or irregular shapes of objects, through the complementarity of image data.

[0022] (3) This utility model provides a vision automatic line control device, which integrates a control unit and an image processing module through a drive module. It can process the data collected by the first detection camera and the second detection camera in real time, and optimize the image quality by using a low aperture and automatic gain mode. It ensures a fast response in the detection process. Real-time processing can identify abnormalities and feed them back to the control system in an instant. The direct effect is to shorten the detection cycle and improve the efficiency of the production line. Compared with the prior art, image processing often has a delay, which affects the smoothness of automation. Real-time not only reduces downtime due to faults, but also provides support for predictive maintenance through data accumulation. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a visual automatic line control device includes: an automatic transport platform 2, two U-shaped bars 3 disposed on the top of the automatic transport platform 2, and two sets of detection components 5 disposed between the two U-shaped bars 3;

[0030] like Figures 1-3 As shown, both U-shaped rods 3 are fixedly connected to the top of the automated transport platform 2, and a second detection camera 6 is fixedly connected to one side of one of the U-shaped rods 3;

[0031] The detection component 5 includes: two slide rails 501, which are fixedly mounted between two U-shaped rods 3. The slide rails 501 are linear guide rails, and the same first detection camera 502 is slidably connected to the two slide rails 501. The first detection camera 502 and the second detection camera 6 are CCD vision detectors. Two brackets 1 are fixedly connected to the bottom of the automatic transport platform 2. The center of the field of view of the second detection camera 6 coincides with the geometric center of the automatic transport platform 2. The movement paths of the two first detection cameras 502 are symmetrically distributed on the left and right sides of the field of view of the second detection camera 6. The movement directions of the two first detection cameras 502 are opposite, and the two first detection cameras 502 correspond to the left and right sides of the automatic transport platform 2, respectively.

[0032] The first detection camera 502 and the second detection camera 6 are set to low aperture and automatic gain mode when acquiring images, and the image processing module is configured to perform real-time analysis on the images acquired by the first detection camera 502 and the second detection camera 6.

[0033] The top of the two U-shaped rods 3 is provided with a drive module 4, which includes a drive motor, a transmission mechanism, a control unit, an image processing module and a detection sensor. The drive motor is connected to the first detection camera 502 through the transmission mechanism to drive the first detection camera 502 to move back and forth along the slide rail 501. The control unit is configured to process the image data collected by the first detection camera 502 and the second detection camera 6.

[0034] It should be noted that the automated transport platform 2, U-shaped bar 3, detection component 5 and drive module 4 are configured to achieve efficient visual inspection function;

[0035] Specifically, the first detection camera 502 can move back and forth along the slide rail 501, precisely controlled by the drive module 4. This dynamic adjustment capability enables the camera to adapt to different positions and size changes of items on the automatic transport platform 2, thereby significantly improving the coverage and adaptability of the detection range.

[0036] By scanning with a moving camera, the device can effectively avoid blind spots caused by a fixed viewing angle, ensuring comprehensive monitoring of transported goods. This not only enhances detection accuracy but also reduces the risk of misjudgment due to item displacement or irregular shape, thereby improving the reliability and stability of automated production lines.

[0037] The coordinated layout of the fixed second detection camera 6 and the mobile first detection camera 502 further optimizes the detection effect. The second detection camera 6 is located at the center of the automated transport platform 2, with the center of the field of view coinciding with the geometric center, providing a stable reference detection point. The two first detection cameras 502 are symmetrically distributed on the left and right sides and move in opposite directions, forming a complementary detection network. This combination ensures synchronous coverage of the platform center and edge areas, achieving image acquisition without blind spots. This maintains high robustness in environments with changing light or irregular object shapes, reduces the need for manual intervention, and improves the overall system's detection integrity and accuracy through the complementarity of image data.

[0038] The drive module 4 integrates a control unit and an image processing module, which supports real-time processing of data acquired by the first and second detection cameras 6, and optimizes image quality by combining low aperture and automatic gain modes, enabling the detection process to respond quickly and identify anomalies.

[0039] This real-time capability not only shortens the inspection cycle and improves production line efficiency, but also supports predictive maintenance through data accumulation, reducing downtime due to failures. Compared with traditional delayed processing methods, it significantly enhances the smoothness and reliability of automated systems.

[0040] When this utility model is in use, the device body is stably supported by the bracket 1, the automatic transport platform 2 starts to operate slowly, and the item is smoothly transported to the detection area. At this time, the second detection camera 6 on the U-shaped rod 3 is in place, and the center of the field of view is aligned with the geometric center of the platform to provide a reference for subsequent detection.

[0041] The control unit of drive module 4 starts a self-test program to verify that the first detection camera 502 and the second detection camera 6 are functioning normally. The entire device enters standby mode and waits for further instructions.

[0042] During the detection execution phase, the staff triggers the operation command of the drive module 4. The drive motor controls the first detection camera 502 to move back and forth along the slide rail 501 through the transmission mechanism. The two first detection cameras 502 move symmetrically in opposite directions, respectively covering the left and right sides of the automatic transport platform 2.

[0043] The second detection camera 6 remains in a fixed position and continuously acquires images of the central area of ​​the platform, while the first detection camera 502 slides on the slide rail 501 and uses a low aperture and automatic gain mode to optimize image acquisition, ensuring clear data is obtained under different lighting conditions.

[0044] During the movement, the detection sensors monitor the camera position in real time, and the control unit coordinates the synchronous operation of the first detection camera 502 and the second detection camera 6 to form a dynamic detection network and avoid blind spots.

[0045] Finally, the image processing module performs real-time analysis on the images acquired by the first detection camera 502 and the second detection camera 6, controls the data stream to process the data, identifies the features or anomalies of the items, and outputs the results for reference in subsequent operations.

[0046] After the inspection is completed, the drive module 4 stops the movement of the first inspection camera 502, the automatic transport platform 2 continues to run until the item is removed, and the system automatically enters standby mode. The staff can repeat the above steps or turn off the device as needed.

[0047] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
