Description

Technical Field

[0001] This utility model relates to the field of ceramic testing technology, and in particular to an auxiliary tooling for ceramic defect detection. Background Technology

[0002] Ceramics are a type of product made primarily from inorganic non-metallic minerals such as natural clay, feldspar, and quartz, through processes including batching, molding, drying, and high-temperature sintering. As an inorganic non-metallic solid material, ceramics are hard and chemically stable after firing, possessing excellent corrosion resistance, wear resistance, and insulation properties. They are not easily corroded by acids or alkalis. The categories of ceramics are very broad, including everyday ceramics such as bowls, plates, and teaware, as well as architectural ceramics such as ceramic tiles and bathroom fixtures.

[0003] In existing technologies, when inspecting ceramic workpieces, the rotation of the workpiece is usually achieved by directly driving the turntable with a motor. However, it is difficult to effectively convert the high-speed rotation of the motor into a low-speed, uniform rotation that is suitable for imaging requirements. Large fluctuations in the turntable speed can easily cause uneven rotation speed of the ceramic workpiece, resulting in blurry images captured by machine vision, poor imaging stability, and difficulty in adapting to high-precision defect detection conditions, thus affecting imaging quality and detection results. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary tooling for ceramic defect detection.

[0005] This utility model is achieved by the following technical solution: an auxiliary tooling for detecting ceramic defects, including a base plate, a display and control board fixedly connected to the outer wall of the base plate, a rotating component provided on the top of the base plate, and an adjustment component provided on the top of the rotating component; The rotating assembly includes a servo motor, the output end of which is fixedly connected to a worm gear, which meshes with a worm wheel, and a rotating rod is fixedly connected inside the worm wheel. A rotating disk is fixedly connected to the top of the rotating rod, and two fixed rods are symmetrically fixedly connected to the bottom of the rotating disk. A rotating ring is rotatably connected to the outer wall of each fixed rod.

[0006] As a further improvement to the above solution, the servo motor is fixedly connected to the outer wall of the base plate, the worm gear is rotatably connected to the inside of the base plate, the rotating rod is rotatably connected to the inside of the base plate, and the rotating ring is rotatably connected to the inner wall of the base plate.

[0007] Through the above technical solution, the worm gear and worm wheel mesh and drive the rotating rod to rotate inside the base plate. The rotating disk fixed at the top of the rotating rod rotates synchronously, thereby driving the ceramic workpiece to rotate at a uniform speed. This achieves workpiece rotation imaging without blind spots, eliminates detection blind zones, and ensures that all surface defects of the workpiece can be completely captured, significantly improving the comprehensiveness and accuracy of the detection. The transmission ratio reduction characteristic of the worm gear and worm wheel can convert the high-speed rotation of the servo motor into the low-speed rotation of the rotating disk, adapting to the imaging needs of different detection conditions and improving the stability of the imaging effect.

[0008] As a further improvement to the above solution, the adjustment component includes a cylinder, which is fixedly connected to the outer wall of the base plate, and a movable frame is fixedly connected to the output end of the cylinder.

[0009] As a further improvement to the above solution, a guide rod is fixedly connected to the bottom of the movable frame, the guide rod is slidably connected to the inner wall of the base plate, and a camera frame is fixedly connected to the bottom of the movable frame away from the guide rod.

[0010] Through the above technical solution, the guide rod slides along the inner wall of the base plate during the movement of the mobile frame. The guide rod effectively limits the movement trajectory of the mobile frame and avoids shaking during the movement.

[0011] As a further improvement to the above solution, the inner wall of the movable frame is provided with an adjustment groove, and a locking rod is slidably connected to the outer wall of the adjustment groove.

[0012] As a further improvement to the above solution, a spring is sleeved on the outer wall of the locking rod, a limiting piece is fixedly connected to the outer wall of the locking rod, a sliding block is slidably connected to the outer wall of the limiting piece, the spring is fixedly connected to the top of the limiting piece, and the end of the spring away from the limiting piece is fixedly connected to the top of the inner wall of the sliding block.

[0013] As a further improvement to the above solution, the sliding block is slidably connected to the inner wall of the movable frame, and a movable camera frame is fixedly connected to the bottom of the sliding block.

[0014] With the above technical solution, once the locking rod disengages from the adjustment groove, the locking limit state of the sliding block can be released. At this time, the moving camera frame can move horizontally, thereby adjusting the distance between the moving camera frame and the outer wall of the ceramic workpiece. This adapts to the inspection needs of ceramics with different diameters and improves the overall flexibility.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a servo motor to drive a worm gear, which meshes with a worm wheel to rotate a rotating rod inside a base plate. A rotating disk fixed at the top of the rotating rod rotates synchronously, causing the ceramic workpiece to rotate at a uniform speed. This achieves seamless rotational imaging of the workpiece, eliminating blind spots and ensuring that all surface defects are completely captured, significantly improving the comprehensiveness and accuracy of the inspection. A fixed rod at the bottom of the rotating disk rotates synchronously, with a rotating ring on the outer side of the fixed rod rotating against the inner wall of the base plate. This rotating ring provides auxiliary support to the bottom of the rotating disk, effectively distributing the rotational load and ensuring smooth rotation throughout. Furthermore, by utilizing the reduction ratio of the worm gear and worm wheel's transmission ratio, the high-speed rotation of the servo motor can be converted into a low-speed rotation of the rotating disk, adapting to different imaging requirements and improving the stability of the imaging effect.

[0016] This invention utilizes a cylinder retraction mechanism to relocate the entire moving frame. During this movement, the guide rod slides along the inner wall of the base plate. Simultaneously, the moving frame moves smoothly while simultaneously moving the camera frame, bringing it to the inner wall of the ceramic workpiece. The moving frame, via sliding blocks mounted on the inner wall, drives the camera frame to move synchronously, allowing the camera frame to irradiate the outer wall of the ceramic workpiece for simultaneous defect detection. Both the camera frame and the moving camera frame are equipped with matching detection cameras and light source illumination devices, enabling simultaneous imaging and defect detection of both the inner and outer walls of the ceramic workpiece. This achieves integrated synchronous inspection of the inner and outer walls of the ceramic workpiece, significantly reducing inspection steps and improving inspection efficiency.

[0017] This invention uses a locking rod to drive a limiting plate to slide on the inner wall of the sliding block and compress a spring. When the locking rod disengages from the adjustment groove, the locking and limiting state of the sliding block can be released. At this time, the sliding block can be manually pushed to slide along the inner wall of the moving frame, causing the bottom moving camera frame to move horizontally and precisely adjust the distance between the moving camera frame and the outer wall of the ceramic workpiece. This adapts to the testing needs of ceramics with different diameters and improves the overall flexibility. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example:

[0021] Please combine Figure 1-5 This embodiment provides an auxiliary tooling for detecting ceramic defects, including a base plate 1, a display control board 2 fixedly connected to the outer wall of the base plate 1, a rotating component 3 on the top of the base plate 1, and an adjustment component 4 on the top of the rotating component 3. The rotating component 3 includes a servo motor 301, a worm gear 302 fixedly connected to the output end of the servo motor 301, a worm wheel 303 meshing with the worm gear 302, a rotating rod 304 fixedly connected inside the worm wheel 303, a rotating disk 305 fixedly connected to the top of the rotating rod 304, and two fixed rods 306 symmetrically fixedly connected to the bottom of the rotating disk 305. A rotating ring 307 is rotatably connected to the outer wall of each fixed rod 306.

[0022] The servo motor 301 is fixedly connected to the outer wall of the base plate 1, the worm gear 302 is rotatably connected to the inside of the base plate 1, the rotating rod 304 is rotatably connected to the inside of the base plate 1, and the rotating ring 307 is rotatably connected to the inner wall of the base plate 1.

[0023] Servo motor 301 drives worm gear 302 to rotate. Worm gear 302 meshes with worm wheel 303 and drives rotating rod 304 to rotate inside base plate 1. Rotating disk 305 fixed at the top of rotating rod 304 rotates synchronously, thereby driving ceramic workpiece to rotate at a uniform speed, realizing workpiece rotation imaging without dead angles, eliminating detection blind spots, ensuring that all surface defects of workpiece can be completely collected, significantly improving detection comprehensiveness and detection accuracy. The rotating ring 307 provides auxiliary support to the bottom of rotating disk 305, effectively distributing the rotation load, making rotating disk 305 rotate smoothly throughout the entire process, and improving the stability of imaging effect.

[0024] The adjustment component 4 includes a cylinder 401, which is fixedly connected to the outer wall of the base plate 1, and a movable frame 402 is fixedly connected to the output end of the cylinder 401.

[0025] A guide rod 403 is fixedly connected to the bottom of the movable frame 402. The guide rod 403 is slidably connected to the inner wall of the base plate 1. A camera holder 404 is fixedly connected to the bottom of the movable frame 402 away from the guide rod 403.

[0026] The inner wall of the movable frame 402 is provided with an adjustment groove 405, and a locking rod 406 is slidably connected to the outer wall of the adjustment groove 405.

[0027] A spring 407 is sleeved on the outer wall of the locking rod 406. A limiting piece 408 is fixedly connected to the outer wall of the locking rod 406. A sliding block 409 is slidably connected to the outer wall of the limiting piece 408. The spring 407 is fixedly connected to the top of the limiting piece 408. The end of the spring 407 away from the limiting piece 408 is fixedly connected to the top of the inner wall of the sliding block 409.

[0028] The sliding block 409 is slidably connected to the inner wall of the movable frame 402, and the bottom of the sliding block 409 is fixedly connected to the movable camera frame 410.

[0029] While the moving frame 402 moves smoothly, it simultaneously drives the camera frame 404 to move to the inner wall of the ceramic. The moving frame 402 drives the moving camera frame 410 to move synchronously through the sliding block 409 mounted on the inner wall, so that the moving camera frame 410 illuminates the outer wall of the ceramic workpiece and performs synchronous defect detection on the outer wall of the ceramic workpiece. This realizes the integrated synchronous detection of the inner and outer walls of the ceramic workpiece, which greatly reduces the detection process and improves the detection efficiency. When the locking rod 406 disengages from the adjustment groove 405, the locking limit state of the sliding block 409 can be released. At this time, the sliding block 409 can be manually pushed to slide along the inner wall of the moving frame 402, which drives the horizontal displacement of the moving camera frame 410 at the bottom. The distance between the moving camera frame 410 and the outer wall of the ceramic workpiece can be precisely adjusted to adapt to the detection needs of ceramics with different diameters, thereby improving the overall flexibility.

[0030] The implementation principle of the ceramic defect detection auxiliary tooling in this embodiment is as follows: A person places the ceramic workpiece at the center of the rotating disk 305, and then controls the equipment to start the detection program via the display control board 2 on the outer wall of the base plate 1. Simultaneously, the display control board 2 can display and analyze the images acquired by the camera frame 404 and the moving camera frame 410, facilitating observation. When the cylinder 401 retracts and drives the moving frame 402 to move as a whole, the moving frame 402 moves, causing the guide rod 403 to slide along the inner wall of the base plate 1. The guide rod 403 effectively limits the movement trajectory of the moving frame 402, preventing shaking during movement. While the moving frame 402 moves smoothly, it simultaneously drives the camera frame 404 to move to... The inner wall of the ceramic workpiece is irradiated by a movable frame 402, which, via a sliding block 409 mounted on the inner wall, drives a movable camera frame 410 to move synchronously. This allows the movable camera frame 410 to irradiate the outer wall of the ceramic workpiece, enabling simultaneous defect detection. Both the camera frame 404 and the movable camera frame 410 are equipped with matching inspection cameras and light source illumination devices, allowing for simultaneous imaging and defect detection of the inner and outer walls of the ceramic workpiece. This achieves integrated synchronous inspection of the inner and outer walls of the ceramic workpiece, significantly reducing inspection steps and improving inspection efficiency. Simultaneously with the camera frame 404 and the movable camera frame 410 capturing images, a servo motor 301 drives a worm gear 302 to rotate. The worm gear 302 meshes with a worm wheel 303, causing a rotating rod 304 to rotate within the base plate 1. The rotating disk 305, fixed at the top of the moving rod 304, rotates synchronously, thereby driving the ceramic workpiece placed on the top of the rotating disk 305 to rotate at a uniform speed. This achieves seamless rotation and imaging of the workpiece, eliminating blind spots and ensuring that all surface defects of the workpiece can be completely captured, significantly improving the comprehensiveness and accuracy of the inspection. During the rotation of the rotating disk 305, the fixed rod 306 at the bottom rotates synchronously with the rotating disk 305. The rotating ring 307 on the outer side of the fixed rod 306 rotates against the inner wall of the base plate 1, providing auxiliary support to the bottom of the rotating disk 305 and effectively distributing the rotational load, ensuring that the rotating disk 305 rotates smoothly throughout the entire process. At the same time, the high-speed rotation of the servo motor 301 can be reduced by utilizing the transmission ratio reduction characteristics of the worm gear 302 and the worm wheel 303. The rotation speed of the rotating disk 305 is converted to low-speed rotation, adapting to the imaging needs of different inspection conditions and improving the stability of the imaging effect. Simultaneously, the locking lever 406 can be pulled outwards. The locking lever 406 causes the limiting piece 408 to slide against the inner wall of the sliding block 409 and compress the spring 407. When the locking lever 406 disengages from the adjusting groove 405, the locking limit state of the sliding block 409 can be released. At this time, the sliding block 409 can be manually pushed to slide along the inner wall of the moving frame 402, causing the bottom moving camera frame 410 to shift horizontally, precisely adjusting the distance between the moving camera frame 410 and the outer wall of the ceramic workpiece. This adapts to the inspection needs of ceramics with different diameters, improving overall flexibility. After adjustment, the locking lever 406 is released, and the spring 407 returns to its original position.Push the locking lever 406 into the corresponding adjustment slot 405, re-locking the sliding block 409 to ensure the camera position remains fixed during the detection process.
