Abstract
Description
Technical Field
[0001] This application relates to the field of sealing strip testing technology, and in particular to a sealing strip testing device. Background Technology
[0002] In modern industrial production, sealing strips are widely used in the automotive industry. Their main function is to prevent liquid leakage, air infiltration, and the entry of foreign objects such as dust, thereby ensuring product performance, quality, and service life. The dimensional accuracy of the sealing strip is crucial to its sealing performance. Dimensional deviations may lead to problems such as incomplete sealing or excessive compression, which in turn affect the overall performance of the machine.
[0003] Traditional methods for inspecting the dimensions of sealing strips have several limitations: 1. Manual measurement using measuring tools is inefficient and unsuitable for the demands of large-scale, high-paced modern production. In the automotive manufacturing industry, component inspection on the production line often requires the testing of a large number of samples within a short period, which manual measurement cannot keep up with. Furthermore, manual measurement is susceptible to the subjective factors of operators, visual fatigue, and limitations in measurement skills, leading to inconsistent and inaccurate results and significant data errors that affect the accurate assessment of sealing strip quality. 2. Using traditional testing equipment, such as laser measuring instruments, typically only allows for the measurement of specific parameters of the sealing strip, such as length, width, or thickness. For complex-shaped sealing strips, multiple devices are often required for comprehensive dimensional inspection, increasing equipment procurement and maintenance costs, reducing the continuity and efficiency of the inspection process, and making the entire process cumbersome and time-consuming.
[0004] With the development of technology, more intelligent testing equipment has emerged on the market, such as the Chinese patent application "A sealing strip size testing device based on visual recognition", application number: CN201921646103.X, which discloses a device including a guide rail slide, a motor for driving the guide rail slide, and a fixture for holding the sealing strip to be tested. It also includes an industrial camera and a light source. The industrial camera and the light source are mounted on the guide rail slide to take pictures of the identification area of the sealing strip to be tested, and obtain the actual size of the sealing strip to be tested based on the pictures.
[0005] The testing equipment described in the aforementioned patent application simplifies the testing process. However, the non-universality of the fixtures limits the equipment's versatility to some extent, making it difficult to adapt to the testing needs of different types of sealing strips. Furthermore, there is room for further improvement in this testing equipment to optimize its testing accuracy. Utility Model Content
[0006] The technical problem to be solved by this application is to provide a sealing strip testing device with the advantages of accurate measurement and high testing efficiency, which is suitable for efficient and accurate dimensional testing of sealing strips of different specifications.
[0007] The technical solution adopted in this application is as follows: a sealing strip testing device, including a frame and a testing component. A testing platform is provided in the middle of the frame. A fixing fixture is detachably installed on the testing platform. A mounting seat for the sealing strip is provided on the fixing fixture. A first grating ruler is provided on the fixing fixture along the X-axis direction. The mounting seat is located close to the first grating ruler. The sealing strip to be tested is embedded in the mounting seat. A moving device is provided on the upper part of the frame. The testing component is installed on the moving device. The testing component is located above the testing platform. The moving device drives the testing component to move repeatedly within its horizontal plane to identify the size of the sealing strip to be tested.
[0008] Compared with the prior art, the advantages of this application are that, firstly, the testing platform can be detachably installed with fixed fixtures, which can adapt to the testing needs of sealing strips of different specifications and shapes. Only the corresponding fixed fixtures need to be replaced, without the need for large-scale modification of the equipment, and the application range is wide.
[0009] Secondly, a first grating ruler is set on the fixed fixture along the X-axis direction. The mounting base is close to the first grating ruler, and the sealing strip to be tested is embedded in the mounting base. The first grating ruler can accurately identify the position information of the sealing strip in the X-axis direction, providing an accurate reference for the detection of the sealing strip size and effectively reducing measurement errors.
[0010] Furthermore, a moving device is installed on the upper part of the frame, and the detection component is mounted on the moving device and located above the detection platform. The moving device's operation allows the detection probe to move repeatedly within its horizontal plane, enabling multiple identification and reading of various positions and dimensional parameters of the sealing strip, thereby improving detection accuracy. This application eliminates the need for manual operation of the detection component's position, significantly improving detection efficiency and meeting the needs of large-scale, high-cycle production.
[0011] In some embodiments of this application, the mounting base includes a main reference strip, a main positioning strip, a side reference strip, and a side positioning strip. The main reference strip is arranged parallel to the first grating ruler and is positioned close to the first grating ruler. The mounting base structure of the above scheme provides a relatively simple and universal fixing method for the sealing strip, enabling the sealing strip to be stably placed on the detection platform, which helps to improve detection accuracy.
[0012] In some embodiments of this application, a gap is left between the main reference strip and the main positioning strip, and the main body of the sealing strip to be tested is embedded between the main reference strip and the main positioning strip.
[0013] In this application, the sealing strip to be tested mainly includes a horizontal segment and a vertical segment, with the vertical segment connecting to the end of the horizontal segment. Correspondingly, the fixing fixture in this application also has a mounting base for the sealing strip to be tested. The layout of the mounting base provides a fixed structure for the horizontal segment of the sealing strip, ensuring its stable placement and thus providing a stable reference for the dimensional measurement of the horizontal segment.
[0014] In some embodiments of this application, both the side reference strip and the side positioning strip are installed outside the main reference strip, with the side reference strip located outside the side positioning strip. A gap exists between the main reference strip and the side reference strip, and a gap also exists between the main positioning strip and the side positioning strip. This arrangement provides a fixed structure for the vertical segment of the sealing strip, ensuring stable placement of the vertical segment and thus providing a stable reference for measuring its dimensions.
[0015] In some embodiments of this application, the fixed fixture is further provided with a second grating ruler, which is disposed near the side reference strip; the second grating ruler is disposed perpendicular to or parallel to the first grating ruler.
[0016] Specifically, if the sealing strip to be tested in this application has a vertical section on only one side, then the preferred solution is to set the second grating ruler perpendicular to the first grating ruler; if both ends of the horizontal section of the sealing strip to be tested are connected to vertical sections, then the preferred solution is to set the second grating ruler parallel to the first grating ruler, and the second grating ruler and the first grating ruler are respectively located at both ends of the side reference strip.
[0017] The second grating ruler provides an additional dimensional measurement reference for measuring the dimensions of the vertical section of the sealing strip or other directions, thereby enhancing the device's measurement capabilities and enabling it to accurately measure the sealing strip in multiple directions.
[0018] In some embodiments of this application, the fixing fixture is provided with quick-clamping clamps along the main reference strip and the side reference strip. When in operation, the quick-clamping clamps press against the sealing strip housed in the mounting base. The design of the quick-clamping clamps allows the sealing strip to be quickly fixed and released during the testing process, improving testing efficiency and ensuring the stability of the sealing strip during the testing process.
[0019] In some embodiments of this application, the moving device includes an X-axis moving assembly and a Y-axis moving assembly. The X-axis moving assembly is mounted on the top surface of the frame and includes two parallel X-axis slide rails. The Y-axis moving assembly is mounted on the two X-axis slide rails and includes two parallel Y-axis slide rails. The detection assembly is mounted on the two Y-axis slide rails. This configuration of the moving device provides the detection assembly with flexible movement capabilities in the horizontal plane, enabling the detection assembly to reach various positions on the sealing strip for dimensional detection, thus improving the comprehensiveness and accuracy of the detection. The arrangement of two X-axis slide rails and two Y-axis slide rails further enhances the stability of the detection assembly's movement.
[0020] In some embodiments of this application, a bracket is mounted on the Y-axis moving assembly, and the detection assembly is mounted on the bracket. The detection assembly includes a CCD vision camera and a sensor. The CCD vision camera moves with the moving device to identify the size of the sealing strip to be detected. The use of the CCD vision camera provides high-precision visual recognition capabilities, enabling rapid capture and analysis of the sealing strip's size information. The sensor design can detect the surrounding environment, avoiding collisions with the sealing strip and protecting the safety of the detection equipment.
[0021] In some embodiments of this application, the sensor is positioned near the CCD vision camera, and the sensor detects whether there are any interfering objects near the CCD vision camera. In other words, the sensor is used to detect whether there are any interfering objects during the movement of the CCD vision camera. The presence of interfering objects can cause collisions with the CCD vision camera, resulting in damage. The sensor is designed to prevent this from happening.
[0022] In some embodiments of this application, the CCD vision camera is mounted on a bracket via a tilt adjustment assembly. The tilt adjustment assembly is connected to an adjustment handle, and the operator operates the adjustment handle to change the angle at which the CCD vision camera is mounted on the bracket. The design of the tilt adjustment assembly allows the CCD vision camera to be adjusted as needed to better capture the dimensional information of the sealing strip at various angles, improving the flexibility and accuracy of the inspection.
[0023] Under normal circumstances, the operator adjusts the CCD vision camera to a horizontal position by adjusting the handle, which provides high detection accuracy. However, if the sealing strip to be detected is large, and some of the areas to be identified are located at the corners of the CCD vision camera's recognition range, then the operator can further adjust the tilt angle of the CCD vision camera to better capture the sealing strip.
[0024] Based on common knowledge in the field, the above-described embodiments can be combined arbitrarily. Attached Figure Description

[0031] The present application will now be described in detail with reference to the accompanying drawings.
[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0033] A sealing strip testing device, embodiment one as follows Figure 1 , Figure 2 As shown, the system includes a frame 1 and a testing assembly 7. A testing platform 2 is located in the middle of the frame 1. A fixing fixture 3 is detachably mounted on the testing platform 2, and a mounting seat for the sealing strip is provided on the fixing fixture 3. The detachable mounting of the fixing fixture 3 on the testing platform 2 can adapt to the testing needs of sealing strips of different specifications and shapes. Only the corresponding fixing fixture 3 needs to be replaced, without the need for large-scale equipment modifications, making it widely applicable.
[0034] A first grating ruler 5 is provided on the fixed fixture 3 along the X-axis direction. The mounting base is located close to the first grating ruler 5, and the sealing strip to be tested is embedded in the mounting base. The first grating ruler 5 can accurately identify the position information of the sealing strip in the X-axis direction, providing an accurate reference for the detection of the sealing strip size and effectively reducing measurement errors.
[0035] A moving device 6 is installed on the upper part of the frame 1, and the detection component 7 is mounted on the moving device 6. The detection component 7 is located above the detection platform 2. The moving device 6 drives the detection component 7 to move repeatedly within its horizontal plane to identify the size of the sealing strip to be detected. This enables multiple identification and reading of multiple positions and size parameters of the sealing strip, thereby improving detection accuracy. This application eliminates the need for manual operation of the detection component 7, greatly improving detection efficiency and meeting the needs of large-scale, high-cycle production.
[0036] Example 2, as Figures 1 to 2 As shown, the mounting base includes a main reference strip 8, a main positioning strip 9, a side reference strip 10, and a side positioning strip 11. The main reference strip 8 is arranged parallel to the first grating ruler 5 and is positioned close to the first grating ruler 5. The mounting base structure described above provides a relatively simple and universal way to fix the sealing strip, enabling the sealing strip to be stably placed on the detection platform 2, which helps to improve detection accuracy.
[0037] A gap is left between the main reference strip 8 and the main positioning strip 9, and the main body of the sealing strip to be tested is embedded between the main reference strip 8 and the main positioning strip 9. In this application, the sealing strip to be tested mainly includes a horizontal segment and a vertical segment, with the vertical segment connecting to the end of the horizontal segment. Correspondingly, the fixing fixture 3 in this application also has a mounting seat for the sealing strip to be tested. The layout of the mounting seat provides a fixed structure for the horizontal segment of the sealing strip, ensuring the stable placement of the horizontal segment, thereby providing a stable reference for the dimensional measurement of the horizontal segment.
[0038] Both the side reference strip 10 and the side positioning strip 11 are installed outside the main reference strip 8. The side reference strip 10 is located outside the side positioning strip 11. There is a gap between the main reference strip 8 and the side reference strip 10, and there is a gap between the main positioning strip 9 and the side positioning strip 11. This layout provides a fixed structure for the vertical section of the sealing strip, ensuring the stable placement of the vertical section, thereby providing a stable reference for the dimensional measurement of the vertical section.
[0039] The fixed fixture 3 is also equipped with a second grating ruler 12, which is positioned near the side reference strip 10. The second grating ruler 12 is positioned perpendicular to or parallel to the first grating ruler 5. Specifically, if the sealing strip to be inspected in this application has a vertical segment on only one side, the preferred solution is to position the second grating ruler 12 perpendicular to the first grating ruler 5. If both ends of the horizontal segment of the sealing strip to be inspected are connected to vertical segments, the preferred solution is to position the second grating ruler 12 parallel to the first grating ruler 5, with the second grating ruler 12 and the first grating ruler 5 located at opposite ends of the side reference strip 10. The placement of the second grating ruler 12 provides additional dimensional measurement references for measuring the dimensions of the vertical segment or other directions of the sealing strip, thereby enhancing the measurement capability of the equipment and enabling it to accurately measure the sealing strip in multiple directions.
[0040] The fixing fixture 3 is equipped with quick-clamping clamps along the main reference strip 8 and the side reference strip 10. When in operation, the quick-clamping clamps press against the sealing strip placed inside the mounting base. The design of the quick-clamping clamps allows the sealing strip to be quickly fixed and released during the inspection process, improving inspection efficiency and ensuring the stability of the sealing strip during the inspection process.
[0041] The rest of the contents of Example 2 are the same as those of Example 1.
[0042] Example 3, as Figures 1 to 4 As shown, the moving device 6 includes an X-axis moving assembly 14 and a Y-axis moving assembly 15. The X-axis moving assembly is mounted on the top surface of the frame 1. The X-axis moving assembly 14 includes two parallel X-axis slide rails. The Y-axis moving assembly 15 is mounted on the two X-axis slide rails and includes two parallel Y-axis slide rails. The detection assembly 7 is mounted on the two Y-axis slide rails. This configuration of the moving device 6 provides the detection assembly 7 with flexible movement capabilities in the horizontal plane, enabling the detection assembly 7 to reach various positions of the sealing strip for dimensional detection, thus improving the comprehensiveness and accuracy of the detection. The arrangement of the two X-axis slide rails and the two Y-axis slide rails further enhances the stability of the movement of the detection assembly 7.
[0043] A bracket 16 is mounted on the Y-axis moving assembly 15, and the detection assembly 7 is mounted on the bracket 16. The detection assembly 7 includes a CCD vision camera 17 and a sensor 18. The CCD vision camera 17 moves with the moving device 6 to identify the size of the sealing strip to be detected. The use of the CCD vision camera 17 provides high-precision visual recognition capabilities, enabling rapid capture and analysis of the sealing strip's size information. The sensor 18 is designed to detect the surrounding environment, preventing collisions with the sealing strip and protecting the safety of the detection equipment.
[0044] The sensor 18 is positioned near the CCD vision camera 17. The sensor 18 detects whether there are any interfering objects near the CCD vision camera 17. In other words, the sensor 18 is used to detect whether there are any interfering objects when the CCD vision camera 17 moves. The presence of interfering objects can cause collisions with the CCD vision camera 17, resulting in damage to the CCD vision camera 17. The sensor 18 is designed to prevent this from happening.
[0045] The CCD vision camera 17 is mounted on the bracket 16 via a tilt adjustment assembly 19. The tilt adjustment assembly 19 is connected to an adjustment handle 20. By operating the adjustment handle 20, the operator changes the angle at which the CCD vision camera 17 is mounted on the bracket 16. The design of the tilt adjustment assembly 19 allows the CCD vision camera 17 to be adjusted as needed to better capture the dimensional information of the sealing strip at various angles, thus improving the flexibility and accuracy of the inspection.
[0046] Under normal circumstances, the operator adjusts the CCD vision camera 17 to a horizontal position by adjusting the handle 20, which provides high detection accuracy. However, if the sealing strip to be detected is large, and some of the areas to be identified are located at the corners within the recognition range of the CCD vision camera 17, then the operator can further adjust the tilt angle of the CCD vision camera 17 to better capture the sealing strip.
[0047] The other contents of Example 3 are the same as those of Example 1 or Example 2.
[0048] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
