Description

Technical Field

[0002] Ceramic insulators require defect detection during production. This detection employs optical methods, using optical principles to capture surface cracks and analyze the material's integrity. However, existing ceramic insulator defect detection devices achieve omnidirectional detection by rotating the device around the insulator. This method has significant drawbacks: during rotation, light casts shadows on the insulator surface, preventing full coverage. Defects in the shadowed areas are difficult to identify, creating blind spots due to insufficient illumination. This issue affects the accurate identification and complete detection of surface defects, easily leading to missed or misjudged defects and significantly reducing the overall detection accuracy of the device.

[0013] This invention also provides a method for detecting defects in ceramic insulators, comprising the following steps: S1. Place the test piece into the light source box and clamp and fix it with the double-end clamping assembly. Then, the defects of the test piece can be detected inside the light source box. S2. Operate the rotating device to make the clamped test piece rotate, which is used to detect defects at different positions of the test piece; S3. Using the pendulum light control unit, the illumination angle of the light source can be controlled, allowing the light to sweep back and forth across the inspection piece, breaking the illumination limitations of a fixed light source, and making the light evenly cover the inspection piece, so as to accurately capture defect information of various parts of the inspection piece.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) Both sides of the test piece are clamped by retaining blocks. The rotation of the retaining blocks can drive the clamped test piece to rotate, so that it rotates continuously in front of the first detector. This avoids the situation where the first detector needs to rotate around the test piece, which would cause shadows to be projected onto the test piece. This further reduces the limitations of the device's detection. At the same time, it avoids the reference position of the first detector from changing continuously, which would cause the reference reference to change during detection and affect the detection results. This further improves the detection accuracy of the device and enhances the detection stability of the device. It is worth mentioning that when the retaining blocks rotate, the rotating blocks on several bent connecting rods also limit the rotation of the rotating blocks in the rotating groove, thus limiting the rotation of the retaining blocks that are used to clamp the test piece and rotate on their own axis. The guiding mechanism prevents instability of the fixed circular block during rotation, thus avoiding instability of the rotating detection component when clamped. This further improves its rotational stability and ensures the detection accuracy of the component. Furthermore, during the defect detection of insulators, the first detector does not need to rotate around the detection component, preventing light from casting shadows on the surface of the component. This allows the light source to cover the entire detection area, avoiding shadowed areas and ensuring that internal defects can be identified. No blind spots are created due to lighting defects, preventing this problem from affecting the accurate identification and complete detection of surface defects on the insulator. This avoids missed detections and misjudgments, significantly improving the overall detection accuracy of the device. (2) Under the action of the fixing cylinder and the fixing spring, the fixing block drives the fixing cylinder to move closer to the end of the support column, so that the fixing clamp on the fixing cylinder contacts the end of the support column, and the end of the support column on both sides of the test piece is contacted by the two fixing clamps, thus clamping the test piece, and the first detector can be used to detect defects in the clamped test piece; by continuing to operate the movement of the positioning slide column, the fixing cylinder on the fixing block continues to move at the upper limit of the fixing cylinder, so that the fixing spring is in a buffer state, strengthening the contact strength and friction between the fixing clamp and the end of the support column on the test piece, until the rubber block on the fixing block contacts the end of the support column, which means that the fixing block has reached the maximum movement path and has moved into place. Under the action of the rubber block, the friction between the block and the end of the support column is increased, avoiding slippage or rotation during the clamping process, and further improving the clamping effect on the test piece. At this time, the secondary patch on the fixing cylinder and the fixing cylinder contacts the main patch, which means that the test piece is clamped. The operation is complete. The contact between the secondary patch and the primary patch sends signals to the control module, which in turn sends signals to the electrically controlled telescopic rod and the rotary motor to achieve the rotation of the clamped inspection piece. It is worth noting that when the retaining block moves closer to the end of the support column, the second detector on the retaining block can be used to detect defects on the sides of the inspection piece and the support column. The light source can also be set on the retaining block to illuminate the sides of the inspection piece and the support column during inspection. When the sides / ends of the inspection piece are clamped, for example, at the front or back of the inspection piece, distributing the light source around the top, bottom, left, and right of the inspection piece avoids shadows on the surface of the inspection piece during clamping. This ensures full coverage of the inspection piece by the light source, preventing shadowed areas and thus avoiding defects in shadowed areas that are difficult to identify. This improves the detection effect of the device, avoids missed detections and misjudgments, and ultimately enhances the detection accuracy of the device. (3) The double-sided rack on the compound moving block moves back and forth, causing it to mesh with two compound moving gears and rotate back and forth. Under the action of the compound moving shaft, it drives the reflector to swing back and forth. The reciprocatingly swinging reflector set in front of the light source allows the light to sweep back and forth across the inspection piece, breaking the illumination limitations of the fixed light source. This ensures that areas on the surface of the inspection piece at different angles and positions can be evenly covered by light, effectively eliminating the shadow blind spots and reflection dead angles that are easy to occur under fixed illumination. Under the dynamic sweeping light, various defects such as cracks, damage, and dirt on the inspection piece are more likely to show clear light and dark contrast and detailed features, improving the visual identification of defects. The dynamic scanning method avoids the weakening of defect features caused by a fixed light source illuminating from a single angle, reducing missed and false detections caused by a fixed illumination angle. This allows the detection system to capture defect information from various parts of the insulator more comprehensively and accurately, improving the overall accuracy and reliability of the detection. Moreover, this setting method does not require additional adjustments to the detection position of the insulator, making it more adaptable to different specifications and installation angles of the insulator. This further reduces the limitations of the device's use, improving its defect detection effect on insulators while ensuring the device's detection accuracy. (4) By starting the electric telescopic rod, the limit rod on its output end moves away from the rotating disk, so that the limit rod is no longer connected to the limit slot, releasing the limit on the rotating disk and allowing it to rotate normally. It is worth mentioning that when the rotating disk does not need to rotate, the limit rod can be used to limit the rotating disk in the limit slot, preventing the fixed block on it from rotating when the operating parts clamp the test piece, thus affecting the clamping operation and reducing the limitations of the device. (5) Place the ceramic insulator to be tested, i.e., the test piece, onto the support arc block inside the light source box. The outer wall of the support column used to string several insulators together contacts the inner wall of the support arc block. By activating the telescopic cylinder, its output end drives the U-shaped support rod upward, which in turn drives the support arc block upward, causing the test piece placed on the support arc block to move upward until it reaches the light source position set inside the light source box. Then, the double-end clamping assembly can be operated to clamp and fix the test piece, avoiding the impact on the test results due to changes in the position of the test piece during the test, thus improving the test accuracy of the device. At the same time, after the test piece is fixed and clamped by the double-end clamping assembly, the telescopic cylinder can be operated to reset, so that the original support... The supporting arc block of the detection component is reset to its initial position to prevent it from casting shadows on the detection component and to avoid components appearing around the insulator, thus reducing the limitations of the device's use. Once the detection component is clamped, the guide block can be moved to its upper limit on the guide rail, causing the first detector to move and detect different positions on the detection component. At the same time, the power source can be activated, causing its output to drive the rotating block to swing left and right, allowing the first detector on it to swing left and right to detect different angles on the detection component, avoiding blind spots in the detection process, further improving the detection accuracy of the device, and preventing missed detections due to undetected areas.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Implementation examples, by Figures 1 to 14The present invention includes a light source box 1; a detection element 2; the detection element 2 is located inside the light source box 1; a double-end clamping assembly is provided on the light source box 1 for fixing the detection element 2; a pendulum light control unit is provided on a positioning slide column 3; the pendulum light control unit is located inside the light source box 1 for controlling the illumination angle of the light source; a rotating device is provided in a positioning square groove 5; the rotating device is used to drive the clamped detection element 2 to rotate; a telescopic cylinder 18 is installed on the bottom surface inside the light source box 1; a U-shaped support rod 19 is connected to the output end of the telescopic cylinder 18; a supporting arc block 20 is connected to the end of the U-shaped support rod 19; and two sides of the detection element 2. The outer wall of the support column is located on the inner wall of the supporting arc block 20; the guide rail 21 is installed inside the light source box 1; the guide block 22 is slidably connected to the guide rail 21; the guide block 22 is provided with an active seat 23 on the side near the detection piece 2; the guide rail 21 is parallel to the detection piece 2; the guide rail 21 is located behind the light source inside the light source box 1; the rotating block 24 is connected inside the active seat 23; the rotating block 24 is rotatably connected to the active seat 23; the first detector 25 is installed on the side of the rotating block 24 near the detection piece 2; the power source 26 is connected to the active seat 23; the output end of the power source 26 is connected to the rotating block 24; The operator places the ceramic insulator to be tested, i.e., test piece 2, onto the support arc block 20 inside the light source box 1. The outer wall of the support column, used to string several insulators together, contacts the inner wall of the support arc block 20. By activating the telescopic cylinder 18, its output end drives the U-shaped support rod 19 upward, which in turn moves the support arc block 20 upward, causing the test piece 2 placed on the support arc block 20 to move upward until it reaches the light source position inside the light source box 1. Then, the double-end clamping assembly can be operated to clamp and fix the test piece 2, preventing changes in the position of the test piece 2 during testing from affecting the test results and improving the testing accuracy of the device. Simultaneously, after the test piece 2 is fixed and clamped by the double-end clamping assembly, the telescopic cylinder 18 can be operated to reset, returning the support arc block 20, which originally supported the test piece 2, to its initial position. This prevents shadows from being projected onto the test piece 2, thus avoiding the presence of components around the insulator. This reduces the limitations of the device's use. Once the test piece 2 is clamped, the guide block 22 can be moved to the upper limit of the guide rail 21, causing the first detector 25 to move and be used to detect different positions of the test piece 2. At the same time, the power source 26 can be activated, causing its output end to drive the rotating block 24 to swing left and right, allowing the first detector 25 on it to swing left and right, and be used to detect different angles of the test piece 2, avoiding blind spots in the detection process and further improving the detection accuracy of the device. This also avoids the occurrence of missed detections due to undetected local areas. The use of a rotating device can also make the clamped test piece 2 rotate, allowing the first detector 25 to perform defect detection on the test piece 2 from all directions. This avoids the need for the first detector 25 to rotate around the test piece 2, which would cause shadows to form on the surface of the test piece 2 when the light shines on it. This allows the light source to achieve full coverage of the test piece 2, further improving the detection effect of the device.

[0019] The double-ended clamping assembly of this embodiment includes positioning slide columns 3, which are disposed on both sides of the light source box 1; two positioning slide columns 3 are symmetrically arranged and located on both sides of the detection piece 2; positioning blocks 4 are installed on the opposite ends of the two positioning slide columns 3; positioning slots 5 are provided on the opposite ends of the two positioning slide columns 3; positioning blocks 4 are located outside the light source box 1; positioning slots 5 are located inside the light source box 1; a displacement base 12 is connected to the outside of the light source box 1; a displacement screw 13 is installed on the displacement base 12; two threaded areas are symmetrically arranged on the displacement screw 13, and the thread directions of the two threaded areas are opposite; a displacement block 14 is connected to the displacement screw. 13; Two displacement blocks 14 are located in two threaded areas respectively; the displacement blocks 14 are threadedly engaged with the threaded areas; a drive source 15 is installed on the displacement base 12; the output end of the drive source 15 is connected to the displacement lead screw 13; a displacement groove 16 is set on the outside of the light source box 1; a displacement slider 17 is installed on the displacement blocks 14; the displacement slider 17 fits into the displacement groove 16, and the two slide in cooperation; the two displacement blocks 14 are respectively connected to two positioning blocks 4; a positioning spring 27 is sleeved on the positioning slide post 3; one end of the positioning spring 27 is fixedly connected to the outside of the light source box 1, and the other end is fixedly connected to the positioning block 4. The following components are connected: a retaining cylinder 28, connected to the retaining block 11 on the side away from the positioning slide post 3; the opening of the retaining cylinder 28 faces the support column on the side of the detection piece 2; a retaining cylinder 29 is fitted into the opening of the retaining cylinder 28; the retaining cylinder 28 and the retaining cylinder 29 are in sliding fit; a retaining clamp 30 is installed at the end of the retaining cylinder 29 away from the retaining cylinder 28; the end point of the support column on the side of the detection piece 2 is located on the moving path of the retaining clamp 30; the outer wall of the retaining cylinder 29 is provided with several protrusions; the inner wall of the retaining cylinder 28 is provided with several corresponding grooves; the number and position of the grooves correspond one-to-one with the protrusions; the protrusions fit into the grooves. The two slide together; a retaining spring 31 is provided inside the retaining cylinder 28; one end of the retaining spring 31 is connected to the retaining cylinder 29, and the other end is connected to the inner bottom surface of the retaining cylinder 28; a main patch 32 is provided on the inner bottom surface of the retaining cylinder 28; a secondary patch 33 is provided at the end point of the retaining cylinder 29 located inside the retaining cylinder 28; the secondary patch 33 is electrically connected to the main patch 32; a second detector 34 is also provided on the side of the retaining block 11 near the detection element 2; several extension rods 35 are provided on the side of the retaining block 11 near the detection element 2; rubber blocks 36 are connected to the extension rods 35; the end point of the support is located on the moving path of the rubber block 36; The drive source 15 is activated, causing its output end to drive the displacement screw 13 to rotate on the displacement base 12. This causes the two threaded displacement blocks 14 to move relative to each other, allowing them to move within the displacement groove 16 via the displacement slider 17. This, in turn, causes the two positioning blocks 4 to move relative to each other, causing the positioning slide pins 3 on them to move to their upper limit on the light source box 1. This keeps the positioning spring 27 in a buffer state, controlling the moving speed of the positioning slide pins 3 to prevent them from contacting the detection piece 2 too quickly and causing damage. When the two positioning slide pins 3 move relative to each other, the rotating and self-rotating device on the positioning slide pins 3 causes the stationary block 11 to move, bringing it closer to the end of the support column on the side of the detection piece 2. This causes the two retaining blocks 11 on both sides of the test piece 2 to move relative to each other, causing the retaining cylinder 29 to move closer to the support end point under the action of the retaining cylinder 28 and the retaining spring 31. This makes the retaining clamp 30 on the retaining cylinder 29 contact the support end point, so that the support end points on both sides of the test piece 2 are contacted by the two retaining clamps 30, thus clamping the test piece 2. The first detector 25 can then perform defect detection on the clamped test piece 2. By continuing to operate the movement of the positioning slide 3, the retaining cylinder 28 on the retaining block 11 continues to move at the upper limit of the retaining cylinder 29, so that the retaining spring 31 is in a buffer state, strengthening the contact strength and friction between the retaining clamp 30 and the support end point on the test piece 2, until the retaining block 11... When the rubber block 36 contacts the end point of the support column, it indicates that the retaining block 11 has reached the maximum movement path and has moved into position. The rubber block 36 increases the frictional force between the rubber block and the end point of the support column, preventing slippage or rotation during clamping and further improving the clamping effect on the detection piece 2. At this point, the secondary patch 33 on the retaining cylinder 29 and retaining tube 28 contacts the main patch 32, signifying that the clamping operation on the detection piece 2 is complete. The contact between the secondary patch 33 and the main patch 32 sends a signal to the control module, which in turn sends signals to the electrically controlled telescopic rod 42 and the rotary motor 8 to achieve the rotation of the clamped detection piece 2. It is worth mentioning that when the retaining clamping block 30 moves closer to the end point of the support column, it can... The second detector 34 on the fixed circular block 11 is used to detect defects on the sides and supports of the test piece 2. The light source can also be set on the fixed circular block 11 to illuminate the sides and supports of the test piece 2 during the test. When the sides / ends of the test piece 2 are clamped, for example, at the front and back of the test piece 2, the light source is distributed at the top, bottom, left and right of the test piece 2. This avoids the formation of shadows on the surface of the test piece 2 when the parts are clamped, so that the light source can achieve full coverage of the test piece 2 and avoid the formation of shadowed areas on the test piece 2. This also avoids the situation where defects in the shadowed areas are difficult to identify, improves the detection effect of the device, avoids missed detections and misjudgments, and thus improves the detection accuracy of the device.

[0020] The compound pendulum light control unit of this embodiment includes a compound pendulum base 6, which is installed on both sides of the positioning slide column 3; a positioning base 7 is also connected to the positioning slide column 3; a rotating gear ring 44; several bent connecting rods 10 are connected to the rotating gear ring 44; the rotating gear ring 44 is coaxial with the center of the rotating disk 9; a rotating gear 45 is connected to one side of the positioning base 7; a compound pendulum turntable 46 is connected to the other side of the positioning base 7; the compound pendulum turntable 46 and the rotating gear 45 are rotatably engaged; the rotating gear 45 and the rotating gear ring 44 are meshed; a compound pendulum column 47 is connected to the edge of the compound pendulum turntable 46 away from the positioning base 7; a rotating base 48 is installed on the positioning base 7; and a guide slide column 49 is connected through the compound pendulum base 6. Above; the repeating base 6 and the guide slide column 49 are slidably engaged; the repeating torque block 50 is connected to the guide slide column 49; the repeating torque block 50 is located on the side of the repeating turntable 46 away from the positioning base 7; the repeating slide groove 51 is connected through the repeating torque block 50 on the side near the repeating turntable 46; the repeating column 47 is fitted into the repeating slide groove 51, and the two are slidably engaged; the double racks 52 are installed on the repeating torque block 50; repeating rotating shafts 53; both repeating rotating shafts 53 are installed on the rotating base 48; one end of the repeating rotating shaft 53 is connected to a reflector 54, and the other end is connected to a repeating gear 55; the two repeating gears 55 are located on both sides of the double racks 52; the double racks 52 and the repeating gears 55 are meshed and connected; When the clamped test piece 2 rotates synchronously through the cooperation of the rotating device and the double-ended clamping assembly, it also drives the rotating gear ring 44 to rotate, which in turn meshes with the rotating gear 45, causing the repeating turntable 46 to rotate. This causes the repeating column 47 on the repeating column to reciprocate within the repeating slide groove 51, and the repeating block 50 on the repeating block 50 to reciprocate at the limit of the repeating base 6 via the guide slide column 49. This, in turn, drives the double-sided rack 52 on the repeating block 50 to reciprocate, meshing with the two repeating gears 55 to reciprocate. Under the action of the repeating shaft 53, the repeating reflector 54 reciprocates, allowing the light to sweep back and forth across the test piece 2, breaking the illumination limitations of a fixed light source. This ensures that areas at different angles and positions on the surface of the test piece 2 are evenly covered by light, effectively eliminating the limitations of fixed illumination. The presence of shadow blind spots and reflective dead zones makes it easier for various defects such as cracks, damage, and dirt on the inspection component 2 to present clear contrasts and detailed features under dynamic scanning light, improving the visual recognition of defects. At the same time, the dynamic scanning method avoids the problem of weakened defect features caused by fixed light source illumination from a single angle, reducing missed detections and false detections caused by fixed illumination angles. This allows the detection system to capture defect information from various parts of the inspection component 2 more comprehensively and accurately, improving the overall accuracy and reliability of the detection. Moreover, this setting method does not require additional adjustments to the inspection position of the inspection component 2, making it more adaptable and able to adapt to inspection scenarios of inspection components 2 with different specifications and installation angles. This further reduces the limitations of the device's use, improves its defect detection effect on insulators, and ensures the device's detection accuracy for insulators.

[0021] The rotating device in this embodiment includes a rotary motor 8, installed in a positioning slot 5; a rotating disk 9 is connected to the output end of the rotary motor 8; a bending connecting rod 10 is connected to the outer wall of the rotating disk 9; several bending connecting rods 10 are arranged equidistantly around the center of the rotating disk 9; a fixing block 11 is connected to several bending connecting rods 10 near the positioning slide 3; a rotating ring 37 is installed on the positioning slide 3; the end point of the positioning slide 3 is located at the center of the rotating ring 37; the rotating ring 37 is coaxial with the center of the rotating disk 9; a rotating groove 38 is disposed on the outer wall of the rotating ring 37; the rotating groove 38 and the rotating ring 9 are connected to each other. The centers of ring 37 are coaxial; a rotating block 39 is connected to the bending connecting rod 10; several rotating blocks 39 are fitted into the rotating groove 38; the rotating blocks 39 and the rotating groove 38 are in sliding fit; a limiting slot 40 is disposed through the rotating disk 9 near the positioning slide post 3; several limiting slots 40 are arranged equidistantly around the center of the rotating disk 9; a storage cavity 41 is disposed on the positioning slide post 3 near the rotating disk 9; an electrically controlled telescopic rod 42 is installed in the storage cavity 41; a limiting insert rod 43 is installed on the output end of the electrically controlled telescopic rod 42; one of the limiting slots 40 is located on the moving path of the limiting insert rod 43; When the control module sends signals to the electrically controlled telescopic rod 42 and the rotary motor 8 in sequence, the activation of the electrically controlled telescopic rod 42 causes the limit plug 43 on its output end to move away from the rotating disk 9, thus deactivating the limit plug 43 from the limit slot 40 and releasing the limit on the rotating disk 9, allowing it to rotate normally. It is worth noting that when the rotating disk 9 is not required to rotate, the limit plug 43 can be used to limit the rotating disk 9 within the limit slot 40, preventing the fixed block 11 on it from rotating during the clamping of the detection piece 2 by the operating components, which would affect the clamping operation and reduce the limitations of the device's use. When the rotating disk 9 can rotate normally... During rotation, the rotary motor 8 is activated, causing its output to drive the rotating disk 9 to rotate. This causes the several bent connecting rods 10 on the disk to rotate synchronously, thereby driving the retaining block 11 to rotate. Some components used to clamp the detection piece 2, such as the retaining cylinder 28 and the extension rod 35, are mounted on the retaining block 11. Since the detection piece 2 is clamped on both sides by the retaining blocks 11, the rotation of the retaining blocks 11 drives the clamped detection piece 2 to rotate, causing it to continuously rotate in front of the first detector 25. This avoids the situation where the first detector 25 needs to continuously rotate around the detection piece 2, resulting in shadows being projected onto the detection piece 2. This step reduces the limitations of the device's detection capabilities and avoids changes in the reference position of the first detector 25 that could affect the detection results due to changes in the reference reference during detection, thus further improving the device's detection accuracy and stability. It is worth mentioning that when the stationary block 11 rotates, the rotating block 39 on several bent connecting rods 10 is also limited to rotate within the rotating groove 38. This limits and guides the rotation of the stationary block 11, which is used to clamp the detection piece 2 and rotates on its own axis, preventing instability of the stationary block 11 during rotation and thus ensuring stability of the clamped detection piece 2. This further improves the device's detection accuracy. This ensures the rotational stability of the detector, guaranteeing the detection accuracy of the detector 2. Furthermore, during the defect detection of the insulator, the first detector 25 does not need to rotate around the detector 2, preventing light from casting shadows on the surface of the detector 2. This allows the light source to fully cover the detector 2, avoiding any shadowed areas. Consequently, any internal defects can be identified, preventing blind spots caused by lighting defects. This avoids the problem of insulator surface defects being affected by the insulator's lack of accuracy and complete detection, thus preventing missed detections and misjudgments and significantly improving the overall detection accuracy of the device.

Place the test piece 2 into the light source box 1 and clamp and fix the test piece 2 with the double-end clamping assembly, so that the defects of the test piece 2 can be detected in the light source box 1. S2. Operate the rotating device to make the clamped test piece 2 rotate, which is used to detect defects at different positions of the test piece 2; S3. Using the pendulum light control unit, the illumination angle of the light source can be controlled, allowing the light to sweep back and forth across the inspection piece 2, breaking the illumination limitations of the fixed light source, so that the light can evenly cover the inspection piece 2, thereby accurately capturing the defect information of each part of the inspection piece 2.
