[0021] Embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Below, reference is made to Figure 1 Describe a visual detection device 100 for a bone densitometer 13 according to an embodiment of the present utility model, including: a carrier table 10, a turntable 11, and a limiting member 12.

[0022] Specifically, as Figure 1 shown, the turntable 11 is provided on the carrier table 10. The bone densitometer 13 is adapted to be arranged on the turntable 11. The limiting member 12 is arranged on the turntable 11, and the limiting member 12 moves along the radial direction of the turntable 11 towards and away from the bone densitometer 13.

[0023] Combined with Figure 1 , the carrier table 10 is the basic platform of the entire detection device, responsible for supporting the turntable 11 and other components. The carrier table 10 has sufficient stability and load-bearing capacity to ensure that during the measurement process, the device can remain stable and reduce the influence of external vibrations on the measurement results. The turntable 11 is arranged on the carrier table 10. The turntable 11 is used to place the bone densitometer 13. The turntable 11 can drive the bone densitometer 13 to rotate to perform visual detection on multiple angles of the bone densitometer 13 and obtain more comprehensive and accurate data. The limiting member 12 is used to adjust the position of the bone densitometer 13 so that the bone densitometer 13 is located at a preset detection position, improving the detection accuracy of the visual detection device 100 for the bone densitometer 13.

[0024] The visual detection device 100 for a bone densitometer 13 according to an embodiment of the present utility model effectively improves the automation level and detection accuracy of the visual detection device 100 for performing visual detection on the bone densitometer 13 by integrating the carrier table 10, the turntable 11, and the limiting member 12. The application of the turntable 11 helps to perform a more comprehensive detection on the bone densitometer 13, and the dynamic adjustment ability of the limiting member 12 enhances the versatility and operation convenience of the visual detection device 100.

[0025] According to some embodiments of the present utility model, as Figure 1 shown, there are a plurality of limiting members 12. The plurality of limiting members 12 are arranged on both sides of the turntable 11 along the radial direction of the turntable 11, and the plurality of limiting members 12 move along the radial direction of the turntable 11 towards the direction of approaching each other and away from each other.

[0026] The carrier table 10 has a first direction and a second direction. A plurality of limit members 12 are arranged on both sides of the turntable 11 at intervals along the first direction of the carrier table 10. There may be two limit members 12. The two limit members 12 extend along the second direction of the carrier table 10. The two limit members 12 are arranged opposite to each other along the first direction of the carrier table 10, and the two limit members 12 can move in the directions of approaching each other and moving away from each other along the first direction of the carrier table 10. The limit member 12 is adapted to be detachably engaged with the bone densitometer 13. When the bone densitometer 13 is located on the turntable 11, the two limit members 12 move in the direction of approaching each other and push the bone densitometer 13 to move to a preset position. After the bone densitometer 13 is in place, the cooperation between the two limit members 12 and the bone densitometer 13 is released, and the two limit members 12 move in the direction of moving away from each other and return to the initial position.

[0027] Thus, the arrangement of the two limit members 12 facilitates the adjustment of the position of the bone densitometer 13. By precisely controlling the coordinated movement of the limit members 12, the automatic positioning and fixation of the bone densitometer 13 are achieved, the operation process is simplified, the detection efficiency and accuracy are improved, and the vision detection device 100 can better meet the detection requirements of the bone densitometer 13.

[0028] According to some embodiments of the present invention, as Figure 1 shown, the vision detection device 100 further includes: a driving member, the driving member is connected to the limit member 12, and the driving member drives the limit member 12 to move along the radial direction of the turntable 11.

[0029] The driving member, as a power source, is connected to the limit member 12. The driving member is used to provide a driving force for the limit member 12 and control the precise movement of the limit member 12 along the radial direction of the turntable 11. Through the linkage between the driving member and the limit member 12, the vision detection device 100 realizes the automatic control of the movement of the limit member 12. The operator only needs to issue an instruction through the control system to precisely control the approaching and separating actions of the limit member 12, complete the automatic alignment and fixation of the bone densitometer 13, greatly reduce manual intervention, and improve the detection efficiency and consistency.

[0030] Thus, the limit member 12 controlled by the driving member can provide fast and accurate positioning ability, which is beneficial to improving the reliability and repeatability of the data collected by the vision detection device 100, and making the detection efficiency and accuracy of the vision detection device 100 higher.

[0031] According to some embodiments of the present invention, as Figure 1 shown, one of the limit member 12 and the carrier table 10 is provided with a slider, and the other of the limit member 12 and the carrier table 10 is provided with a chute. The chute extends along the radial direction of the turntable 11, and the slider is in guiding cooperation with the chute.

[0032] In some embodiments, a slider is formed on the limit member 12, and a slide groove is formed on the support platform 10. The slide groove extends along the first direction of the support platform 10. The slider is fitted in the slide groove, and the slider can move along the first direction of the support platform 10 relative to the slide groove. The guiding and matching mechanism of the slider and the slide groove provides stable guidance and support for the linear motion of the limit member 12, avoiding unnecessary deviation or shaking. The close fit between the slider and the slide groove can not only reduce the friction and resistance during the movement, but also improve the linearity and repeatability of the movement of the limit member 12. The design of the slider and the slide groove is easy to maintain and adjust. If it is necessary to adjust the smoothness of the movement of the limit member 12 or replace the worn parts, the operation is relatively simple, which is conducive to maintaining the good operation state of the equipment for a long time.

[0033] Therefore, through the guiding cooperation between the slider and the slide groove, the visual inspection device 100 not only realizes the precise guidance and stable movement of the limiter 12 in structure, but also functionally ensures the high automation and measurement accuracy of the bone density detection process.

[0034] According to some embodiments of the present invention, Figure 1 As shown, at least one limiting groove is formed on the limiting member 12 , and the limiting groove is suitable for cooperating with at least a part of the bone densitometer 13 .

[0035] A moving wheel is provided at the bottom of the bone densitometer 13, and the limiting groove on the limiting member 12 is suitable for matching with the moving wheel of the bone densitometer 13. When the limiting member 12 moves to contact with the bone densitometer 13 and positions it, the moving wheel of the bone densitometer 13 can be embedded or clamped in the limiting groove, thereby achieving more stable and precise positioning.

[0036] Therefore, the design of at least partial cooperation between the limit groove and the bone densitometer 13 can prevent the bone densitometer 13 from moving due to external force during the detection process, and can also ensure that the starting position of each detection is consistent, which helps the visual detection device 100 obtain repeatable measurement results.

[0037] According to some embodiments of the present invention, the visual inspection device 100 further includes: a moving part and an image acquisition unit, the moving part is movable relative to the turntable 11, and the image acquisition unit is disposed on the moving part.

[0038] The moving member can be a robotic arm, which can move along a predetermined path and in a predetermined manner. It is not limited to radial movement around the turntable 11, but can also be positioned in three-dimensional space, enabling observation and detection of the bone densitometer 13 from various angles and distances. The setting of the moving member greatly expands the coverage range and detection ability of visual inspection. The image acquisition unit (usually an industrial camera) is installed on the moving member. As the moving member moves, the image acquisition unit can accurately capture images of the bone densitometer 13. Industrial cameras usually have high resolution, high-speed shooting ability, and good image stability, and are suitable for quickly and accurately obtaining high-quality images, which is crucial for subsequent image analysis and defect detection.

[0039] Thus, the combination of the moving member and the image acquisition unit enables the visual inspection device 100 to automatically complete the task of image acquisition from different perspectives and positions, effectively improving the comprehensiveness of detection and being able to capture details that may be missed by static detection points. Through software control, precise manipulation of the moving member can be achieved, enabling the image acquisition unit to take pictures at the best position and angle. Then, these images are analyzed through image processing techniques for quality control, defect identification, etc. The integration of the moving member and the image acquisition unit adds dynamic and all-round detection capabilities to the visual inspection device 100, enabling high-efficiency and high-precision automated detection of the visual inspection device 100.

[0040] According to some embodiments of the present invention, as Figure 1 shown, the visual inspection device 100 further includes: a host computer 14, the host computer 14 includes a display 15 and a controller 16, the controller 16 is connected to the display 15, and the controller 16 is connected to the limit member 12, the moving member, and the image acquisition unit.

[0041] The host computer 14 serves as the central control unit of the entire visual inspection device 100, integrating the display 15 and the controller 16, and is the main interface for operators to interact with the detection system. The host computer 14 is responsible for receiving operation instructions, displaying detection status and results, and controlling the coordinated operation of each component. The display 15 is used to display information such as system status, detection images, and data analysis results, enabling the operator to intuitively monitor the detection process, understand the detection progress and results. A good visualization interface design helps improve operation efficiency and reduce misinterpretation. The controller 16 is the core of the host computer 14. The controller 16 manages the actions of the limit member 12, the turntable 11, the moving member, and the image acquisition unit through pre-programming or real-time instructions. According to the detection process and algorithm logic, the controller 16 sends precise motion control instructions to the moving member, adjusts the position of the limit member 12, and simultaneously controls the image acquisition unit to capture images at the appropriate time and position. In addition, the controller 16 is also responsible for processing the data collected by the image acquisition unit, performing image analysis, feature extraction, and judgment and decision-making.

[0042] Thus, through the connection between the controller 16 and each component, the host computer 14 realizes the unified management and intelligent control of the entire vision detection device 100. The operator can set detection parameters, start the detection program, view real-time images and analysis results through the interface of the host computer 14, and can even remotely monitor and adjust the detection process, greatly improving the automation degree and flexibility of the detection. The integration of the host computer 14 enables the vision detection device 100 to not only have the ability of automatic detection, but also possess data processing and human-computer interaction functions, which helps to realize the intelligent and high-efficiency detection of the vision detection device 100.

[0043] According to some embodiments of the present invention, it further includes: an image processing unit, one end of the image processing unit is electrically connected to the display 15, and the other end of the image processing unit is electrically connected to the controller 16.

[0044] As an independent module, one end of the image processing unit is electrically connected to the display 15, and is used to receive the original image data collected by the controller 16 via the moving member and the image acquisition unit. The image processing unit can analyze and process the collected images, save the analysis results (missing characters, incorrect characters, unclear characters, offset) to the database, organize and record the data, generate reports on influencing factors such as the product qualification rate, and display the processed results on the display 15. The other end of the image processing unit is electrically connected to the controller 16, receives control instructions, and at the same time feeds back the analysis results to the controller 16, so that the controller 16 can make corresponding decisions according to the analysis results, such as adjusting detection parameters, controlling the robotic arm to reposition or triggering other operations.

[0045] Thus, by integrating the image processing unit, the vision detection device 100 can not only automatically complete complex image analysis tasks, reduce errors caused by human factors, but also greatly improve the detection speed and accuracy.

[0046] According to some embodiments of the present invention, the display 15 includes a human-machine interface.

[0047] The human-machine interface is used to display an intuitive operation interface, including elements such as graphical menus, buttons, dashboards, alarm prompts, data charts, etc., enabling the operator to easily monitor the device status, input instructions, adjust parameter settings, view detection reports or image analysis results. The operator can achieve instant control of the vision detection device 100 by directly clicking, swiping or inputting information, such as adjusting the angle of the camera, starting the detection program, adjusting image analysis parameters, etc. The human-machine interface also facilitates the operator to manually make a secondary determination of the unqualified images analyzed by the image processing unit.

[0048] Thus, the integrated human-machine interface of the display 15 in the vision detection device 100 can enhance the usability and operation efficiency of the device, improve the transparency and scientific nature of the overall detection process, achieve efficient automated detection of the vision detection device 100, and improve detection accuracy.

[0049] According to some embodiments of the present invention, the vision detection device 100 further includes: an alarm, one end of the alarm is electrically connected to the controller 16, and the other end of the alarm is electrically connected to the display 15.

[0050] As an important safety and status feedback component, the connection method of the alarm ensures that the alarm can monitor defective products in real time and send them to the corresponding positions for repair according to the judgment of the controller 16 or preset conditions during the detection process. Thus, adding the alarm to the vision detection device 100 further strengthens the real-time monitoring and abnormal warning functions of the system.

[0051] Specifically, in combination with Figure 1 , the detection process of the vision detection device 100 for the bone densitometer 13 is as follows:

[0052] First, the operator moves the bone densitometer 13 onto the turntable 11. The host computer 14 controls the driving member to drive the limiting member 12 to move along the first direction of the carrier 10 through the controller 16, and uses the cooperation of the limiting groove and the bone densitometer 13 to accurately fix the position of the bone densitometer 13. The controller 16 sends an instruction, and the moving member starts to move according to the preset path and program, and adjusts the image acquisition unit to the predetermined detection position. Under the guidance of the robotic arm, the image acquisition unit takes images of the bone densitometer 13 from different angles and distances to ensure that the front detection area of the bone densitometer 13 is covered. After the shooting of the front of the bone densitometer 13 is completed, the controller 16 controls the turntable 11 to rotate 180°. The controller 16 sends an instruction to the moving member, so that the moving member and the image acquisition unit collect images of the bone densitometer 13 again, and the comprehensive image collection of the bone densitometer 13 can be completed.

[0053] The captured image data is processed by the image processing unit. The image processing unit saves the analysis results (missing characters, incorrect characters, unclear characters, offset) to the database, and the determination results are displayed in real time on the host computer 14 for the operator to view the passing ratio in real time. If the detection result exceeds the preset threshold or an abnormality is found, the alarm will issue a warning through sound or screen prompt to remind the operator to pay attention. The operator needs to manually perform a secondary determination on the unqualified images to determine whether they can enter the next process. Thus, the detection process of the vision detection device 100 for the bone densitometer 13 can be completed.
