[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figures 1-2 An embodiment of this utility model is provided: a rubber seal surface defect detector, including a test platform 1, a placement plate 2 fixedly connected to the upper surface of the test platform 1, a seal body 3 provided on the upper surface of the placement plate 2, an electric push rod 4 fixedly connected to the upper surface of the test platform 1, and a pressing component 5 provided at the output end of the electric push rod 4.
[0025] Specifically, the testing platform 1 is used to fix the placement plate 2, electric push rod 4, drive motor 6, etc., to provide a stable working platform for the testing of rubber seals. The placement plate 2 is used to place the seal body 3 to be tested. The seal body 3 is used for the rubber seal product to be tested. The electric push rod 4 is used to provide thrust to the pressing assembly 5. The pressing assembly 5 is used to clamp and fix the seal body 3, thereby reducing human error.
[0026] Reference Figures 2-3 The pressing component 5 includes a lifting lug 501. The bottom end of the lifting lug 501 is fixedly connected to the output end of the electric push rod 4. A transmission plate 502 is rotatably connected inside the lifting lug 501. A rotating column 503 is fixedly connected inside the transmission plate 502. A connecting plate 504 is rotatably connected to the outer wall of the rotating column 503. A first support plate 505 is rotatably connected to the outer wall of the connecting plate 504. A fixing plate 506 is fixedly connected to the bottom end of the first support plate 505. The outer wall of the fixing plate 506 is fixedly connected to the outer wall of the placement plate 2. A clamping plate 507 is fixedly connected to the outer wall of the transmission plate 502.
[0027] Specifically, the lifting lug 501 is used to transmit the power of the electric push rod 4 to the transmission plate 502. The transmission plate 502 is used to swing with the extension and retraction of the electric push rod 4 under the rotational connection of the lifting lug 501, driving the clamping plate 507 to press down or lift up. The rotating column 503 is used to support the rotation of the transmission plate 502. The connecting plate 504 is used to provide stability for the swing of the transmission plate 502. The first support plate 505 is used to support the rotation of the connecting plate 504. The fixing plate 506 is used to fix it to the outer wall of the placement plate 2, so that the support position of the pressing component 5 is fixed. The surface of the clamping plate 507 is made of flexible silicone material, which avoids damage such as indentation and tearing to the surface of the rubber seal while applying clamping force, thereby achieving the effect of batch testing and improving the overall testing efficiency.
[0028] Reference Figure 1 and Figure 4 A drive motor 6 is fixedly connected to the upper surface of the testing platform 1. A threaded rod 7 is connected to the output end of the drive motor 6. A second support plate 8 is rotatably connected to one end of the threaded rod 7. The lower surface of the second support plate 8 is fixedly connected to the upper surface of the testing platform 1. A second scissor arm 12 is rotatably connected to the outer wall of the second support plate 8. A pulley 13 is fixedly connected to the outer wall of the second scissor arm 12. A transmission block 9 is threadedly connected to the outer wall of the threaded rod 7. A first scissor arm 10 is rotatably connected to the outer wall of the transmission block 9. A sliding plate 11 is rotatably connected to the outer wall of the first scissor arm 10. A sliding plate 11 is rotatably connected to the outer wall of the first scissor arm 10. A sliding groove 14 is provided inside the sliding plate 11. A slider 15 is fixedly connected to the outer wall of the sliding plate 11. A testing camera 17 is provided on the upper surface of the sliding plate 11. A slide rail 16 is fixedly connected to the upper surface of the testing platform 1. The outer wall of the slider 15 is slidably connected to the inside of the slide rail 16. The outer wall of the pulley 13 is slidably connected to the inside of the slide groove 14.
[0029] Specifically, the drive motor 6 drives the threaded rod 7 to rotate, thereby causing the transmission block 9 to move on the threaded rod 7. The threaded rod 7 converts the rotational motion of the drive motor 6 into the linear motion of the transmission block 9. The second support plate 8 supports the rotation of the threaded rod 7 and serves as the fulcrum for the rotation of the second scissor arm 12. The second scissor arm 12 cooperates with the first scissor arm 10. Through the sliding of the pulley 13 in the slide groove 14, the sliding plate 11 is raised and lowered. The pulley 13 slides in the slide groove 14 to reduce the friction between the second scissor arm 12 and the sliding plate 11, making the raising and lowering action of the sliding plate 11 smoother. The transmission block 9 moves along the threaded rod 7 under the drive of the threaded rod 7, and through a rotational connection, drives the first scissor arm 10 to swing, thereby pushing the sliding plate 11 to move. The 0 is used to convert the linear motion of the transmission block 9 into the horizontal movement and lifting motion of the sliding plate 11 through the swinging action. It rotates on the outer wall of the second scissor arm 12. The sliding plate 11 is used to support the detection camera 17 and, driven by the first scissor arm 10 and the second scissor arm 12, cooperates with the slider 15 to achieve smooth movement of the detection camera 17. The slide groove 14 is used to provide a sliding track for the pulley 13. The slider 15 is used to slide and connect with the slide rail 16 to limit the movement direction of the sliding plate 11. The slide rail 16 is used to provide a sliding track for the slider 15. The detection camera 17 is used to capture the surface image of the sealing body 3 and detect the surface defects of the sealing through image recognition technology, thereby avoiding image distortion caused by too close or too far distance and ensuring that the defect recognition algorithm can accurately analyze the surface details.
[0030] Working principle: When the surface defect detector for rubber seals is needed, first start the electric push rod 4, and use the electric push rod 4 to push the lifting lug 501 to move upward, thereby driving the transmission plate 502 to rotate. At the same time, the rotating column 503 rotates, thereby driving the clamping plate 507 to press down, thereby fixing the position of the seal body 3 and achieving the effect of improving the accuracy of defect identification.
[0031] When the surface defect detector for rubber seals is needed, first start the drive motor 6. The drive motor 6 drives the threaded rod 7 to rotate, causing the transmission block 9 to move linearly along the threaded rod 7. This causes the transmission block 9 to move the first scissor arm 10. At the same time, the second scissor arm 12 slides in the groove 14 of the sliding plate 11 through the pulley 13, thereby driving the sliding plate 11 to move. This causes the slider 15 to slide on the slide rail 16, which in turn drives the detection camera 17 to move. This allows for easy imaging of the surface of the seal body 3 from different heights, achieving the effect of adapting to seal bodies 3 of different thicknesses.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
