[0002] After the porcelain insulators are manufactured, their outer surfaces need to be inspected. They can only be put into use after passing the inspection and meeting the relevant standardization requirements.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The multi-view optical scanning architecture of “insulator self-rotation + visual module stationary” is adopted, which abandons the traditional detection scheme of visual module rotating around insulator, reduces the overall space occupied by the device, and significantly improves the versatility and practicality of the device; eliminates the vibration interference generated during the rotation of the visual module from the root, avoids the problem of image blurring, and greatly improves the detection accuracy.

[0018] 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.

[0019] Implementation examples, by Figures 1 to 14The present invention includes a retaining base 1; a detection element 2; a main vision module 3 mounted on the side of the retaining base 1; a plurality of main vision modules 3 arranged vertically at equal intervals; the detection element 2 is located on the side of the retaining base 1, and the main vision modules 3 are located on the side of the retaining base 1 closer to the detection element 2; a retaining rotation device is provided on the retaining base 1 for clamping the detection element 2 and driving it to rotate; the retaining rotation device includes: a guide slot 4, which is disposed through the side of the retaining base 1; a dual-axis motor is installed in the middle of the guide slot 4. 5; Guide screws 6, installed on opposite sides within guide slots 4; two guide screws 6 are symmetrically arranged about the dual-axis motor 5 as the axis of symmetry; the opposite ends of the two guide screws 6 are connected to the corresponding output ends of the dual-axis motor 5; guide block 18, threadedly connected to the guide screws 6; guide sliders 19 are installed on both sides of the guide block 18; guide groove 20, located on opposite sides of guide slots 4; guide sliders 19 and guide groove 20 fit together, and the two slide in cooperation; displacement plate 21, installed... On the guide block 18; two displacement horizontal plates 21 are connected through displacement cylinders 22 on their opposite faces; the displacement cylinders 22 and the displacement horizontal plates 21 are in sliding fit; the detection element 2 is located between the two displacement horizontal plates 21; a displacement limiting plate 23 is connected to the end of the displacement cylinder 22 away from the end face of the detection element 2; a fixing clamp 24 is connected to the end of the displacement cylinder 22 near the end face of the detection element 2; a drive motor 25 is installed inside the fixing clamp 24; a drive block 26 is connected to the output end of the drive motor 25; the drive block 26... A rubber pad 27 is connected to the end of block 26 away from the drive motor 25; the end face of the detection element 2 is located on the moving path of the rubber pad 27; a displacement spring 28 is sleeved on the displacement cylinder 22; one end of the displacement spring 28 is fixedly connected to the displacement limiting plate 23, and the other end is fixedly connected to the displacement horizontal plate 21; an auxiliary vision module 29 is installed on the side of the fixing clamp 24 near the end face of the detection element 2; signal contact pieces 30 are provided on the opposite surfaces of the displacement horizontal plate 21 and the drive motor 25; the two signal contact pieces 30 are electrically connected. The porcelain insulator to be tested, i.e., the test piece 2, is placed horizontally between two driving blocks 26, with both end faces of the test piece 2 facing the rubber pads 27 on both sides. The dual-axis motor 5 is started, and the dual-axis motor 5 synchronously drives the guide screws 6 on both sides to rotate, causing the two threaded guide blocks 18 to move synchronously towards each other along the guide groove 4. The fit between the guide slider 19 and the guide groove 20 provides precise guidance for the guide blocks 18 throughout the entire process, preventing radial deviation. The guide blocks 18 drive the displacement plate 21 to move synchronously towards the test piece 2. The displacement plate 21 drives the fixing plate 24, the drive motor 25, and the driving blocks 26 to move synchronously through the displacement cylinder 22. When the rubber pad 27 at the end of the driving block 26 contacts the test piece 26, the test piece 28 is successfully tested. When the end face of the test piece 2 is being inspected, the test piece 2 is clamped and positioned. As the guide block 18 continues to move, the displacement plate 21 moves to its upper limit on the displacement cylinder 22, compressing the displacement spring 28. The uniform elastic force generated by the displacement spring 28 causes the rubber pad 27 to fit tightly against the end face of the test piece 2, achieving flexible clamping of the test piece 2 and preventing damage to the porcelain insulator end face from rigid clamping. As the guide block 18 continues to move towards each other, the displacement plate 21 gradually approaches the back of the drive motor 25. When the two signal contacts 30 make contact and conduct, the dual-axis motor 5 automatically stops running. At this point, the clamping force reaches the preset maximum value, ensuring both the firmness of the clamping and preventing the test piece 2 from dislodging during rotation, while also allowing the signal contacts 30 to conduct. The system monitors the clamping status in real time to ensure the on / off state. If the detection element 2 becomes loose or dislodged, the system will immediately issue an alarm signal and stop the machine, improving the safety of the device operation. At the same time, it will send a signal to the drive motor 25, which will drive the drive block 26 to rotate synchronously. The friction between the rubber pad 27 and the end face of the detection element 2 will cause the detection element 2 to rotate at a constant speed around its own central axis. At this time, multiple main vision modules 3 arranged vertically at equal intervals on the fixation base 1 remain stationary and perform continuous optical scanning on the outer surface of the detection element 2 during the rotation. The main vision module 3 can be manually adjusted to adjust the pitch angle, covering all areas such as the upper and lower surfaces of the porcelain insulator skirt and the rod, completely eliminating blind spots in the detection. Meanwhile, the auxiliary vision modules on the fixation clamp 24... The vision module 29 simultaneously scans both ends of the test piece 2 during clamping, achieving omnidirectional, blind-angle-free inspection of the outer surface and both ends of the test piece 2. This enables the device to adopt an inspection method of "insulator rotation + stationary vision module," abandoning the traditional scheme of the vision module rotating around the insulator. This significantly reduces the overall space occupied by the device, improves its versatility and practicality, and avoids image blurring caused by vibration during the rotation of the vision module, thus avoiding instability of the vision module and greatly improving the detection accuracy of the device. The collected data is analyzed by visual intelligence, and after meeting the relevant standardization requirements, the detection conclusion is drawn, completing the visual inspection of the porcelain insulator and realizing the full surface quality inspection of the porcelain insulator.

[0020] In this embodiment, the fixed base 1 is further provided with a counter-positioning mechanism for positioning the detection piece 2. The counter-positioning mechanism includes: a positioning base plate 7, which is installed on the side of the fixed base 1 away from the detection piece 2; a positioning gear 8 is installed on the positioning base plate 7; two positioning gears 8 are symmetrically arranged; a bent rod 9 is connected to the positioning gear 8; a limiting tube 10 is installed on the bent rod 9; both ends of the limiting tube 10 are fitted with limiting columns 11; the limiting columns 11 and the limiting tube 10 are slidably engaged; and a limiting spring 12 is disposed inside the limiting tube 10; one end of the limiting spring 12 is flush with the inner bottom surface of the limiting tube 10. One end is fixedly connected to the other end, and the other end is fixedly connected to the limiting square post 11; the blocking slide cylinder 13 is installed on the limiting square post 11; the blocking slide cylinder 13 is fitted with the blocking slide column 14 on the side near the side of the detection piece 2; the blocking slide column 14 and the blocking slide cylinder 13 are in sliding cooperation; the blocking spring 15 is set inside the blocking slide cylinder 13; one end of the blocking spring 15 is fixedly connected to the blocking slide cylinder 13, and the other end is fixedly connected to the blocking slide column 14; the blocking square seat 16 is installed at the end of the blocking slide column 14 near the side of the detection piece 2; the blocking round wheel 17 is connected inside the blocking square seat 16; the arc surface at the end of the detection piece 2 is located on the movement path of the blocking round wheel 17. The following components are included: a retaining base 31, mounted on a guide block 18; a fixed pulley 32, mounted on the side of the retaining base 1 away from the detection piece 2; a retaining base 33, mounted on the side of the retaining base 1 away from the detection piece 2; a retaining rotating shaft 34 is connected through the side of the retaining base 33, and the two rotate in cooperation; a winding roller 35, mounted on the retaining rotating shaft 34; a spring 36, connected to the retaining rotating shaft 34; the end of the spring 36 is fixedly connected to the retaining base 33; a cable 37, one end connected to the retaining base 31, the other end passing over the fixed pulley 32 and then wound around the winding roller 35; and a retaining gear 38. Mounted on the retaining shaft 34; a drive base 39 is mounted on the retaining base 33; a drive slide column 40 is connected through the drive base 39 near the retaining platform 1; drive blocks 41 are connected to both ends of the drive slide column 40; a retaining rack 42 is connected to both drive blocks 41; the retaining rack 42 is meshed with the retaining gear 38; a drive spring 43 is sleeved on the drive slide column 40; one end of the drive spring 43 is fixedly connected to the drive block 41, and the other end is fixedly connected to the drive base 39; a double rack 44 is mounted on the retaining rack 42; the double rack 44 is located between the two positioning gears 8 and meshes with each other; When the dual-axis motor 5 drives the two guide blocks 18 to move synchronously towards each other to clamp the detection piece 2, the retaining seats 31 fixed on the guide blocks 18 will move synchronously, pulling the cable 37. After the cable 37 passes around the fixed pulley 32, it drives the winding roller 35 and the retaining shaft 34 to rotate, causing the spring spring 36 to tighten and store energy. The retaining shaft 34 drives the retaining gear 38 to rotate synchronously. The retaining gear 38 drives the retaining rack 42 to move along the drive slide column 40 away from the retaining base 1 through meshing transmission, compressing the drive spring 43. The retaining rack 42 drives the double racks 44 to move synchronously. The double racks 44 mesh simultaneously to drive the racks on both sides. The two positioning gears 8 rotate in opposite directions, driving the corresponding bent rods 9 to rotate towards the detection piece 2. The bent rods 9, through the limiting square tube 10, limiting square post 11, blocking slide tube 13, and blocking slide post 14, drive the blocking wheel 17 to move towards the side of the detection piece 2 until the blocking wheel 17 is tightly fitted against the two arc surfaces at the end of the detection piece 2. At this time, the elastic force generated by the compression of the blocking spring 15 keeps the blocking wheel 17 in a pressed state. During the rotation of the detection piece 2, the blocking wheel 17 rotates synchronously with the detection piece 2, providing radial positioning for the detection piece 2 and preventing it from rotating in the wrong direction. During rotation, radial offset and sway occur, ensuring that the central axis of the detection piece 2 remains perpendicular to the scanning plane of the main vision module 3, thus improving the accuracy of optical scanning. On the other hand, the elastic force of the damping spring 15 can absorb the vibration and impact generated during the rotation of the detection piece 2, further improving the stability of the rotation of the detection piece 2 and avoiding image blurring due to vibration. After the detection is completed, the dual-axis motor 5 rotates in the opposite direction, driving the guide block 18 to move synchronously in opposite directions, releasing the clamp on the detection piece 2. At this time, the cable 37 slackens, and the spring 36 releases its stored energy, driving the fixed rotating shaft 34 and the winding roller 35 to rotate in opposite directions, retracting the cable 37. The reverse rotation of the retaining gear 38 drives the retaining rack 42 and the double racks 44 to reset, which in turn drives the two bent rods 9 to rotate in opposite directions, causing the blocking wheel 17 to disengage from the detection piece 2, facilitating the removal of the detection piece 2. This mechanism cleverly utilizes the clamping power of the retaining rotation device to achieve synchronous positioning of both sides of the detection piece 2 through pure mechanical linkage. No additional independent drive source is required, reducing device cost and energy consumption. At the same time, it works in conjunction with the retaining rotation device to form a multi-fixed structure of "clamping at both ends + positioning on both sides", effectively preventing the detection piece 2 from shifting and shaking during the rotation process, and significantly improving the stability and accuracy of the detection.

[0021] In this embodiment, a position adjustment control unit is provided on the limiting square tube 10; the number and position of the position adjustment control unit correspond to the limiting square column 11; the position adjustment control unit includes a brake slot 45, which is disposed through the side of the limiting square column 11; a plurality of brake slots 45 are arranged at equal intervals; a brake base plate 46 is installed on both sides of the limiting square tube 10; a brake cylinder 47 is connected through the brake base plate 46, and the two are slidably engaged; one end of the two brake cylinders 47 is respectively connected to a brake limiting plate 48, and the other end is connected to a brake pull plate 49; a brake spring 50 is sleeved on the brake cylinder 47; one end of the brake spring 50 is fixedly connected to the brake limiting plate 48, and the other end is fixedly connected to the brake base plate 46; a brake plug 51 is fixedly installed on the side of the brake pull plate 49 near the brake slot 45; after the brake plug 51 passes through the limiting square tube 10, it is connected to one of the brake slots 45; When it is necessary to test porcelain insulators of different sizes, pull the brake plate 49 outward. The brake plate 49 drives the brake cylinder 47 and brake block 51 to move outward, compressing the brake spring 50, so that the brake block 51 is pulled out of the brake slot 45 on the limiting column 11, releasing the locking of the limiting column 11. At this time, the extension length of the limiting column 11 in the limiting cylinder 10 can be adjusted up and down according to the size and center of gravity of the test piece 2, thereby adjusting the clamping height of the braking wheel 17 so that the braking wheel 17 can be clamped near the center of gravity of the test piece 2, preventing the test piece 2 from tilting and shaking due to instability of the center of gravity. After the adjustment is completed, release the brake plate 49. The brake spring 50 releases its elastic potential energy, pushing the brake plate 49 and brake block 51 to move inward, so that the brake block 51... Insert the device into the brake slot 45 at the corresponding height to lock and fix the limiting column 11. In the locked state, the limiting spring 12 inside the limiting tube 10 is compressed, and the elastic force it generates will continue to act on the limiting column 11, so that the side wall of the brake slot 45 and the brake block 51 fit tightly together, significantly increasing the static friction between the two, effectively preventing the brake block 51 from accidentally coming out due to vibration or other non-human factors, and improving the reliability of locking. This unit enables the rapid adjustment of the clamping height of the braking wheel 17, which can be adapted to the testing needs of porcelain insulators of different specifications and sizes, greatly improving the versatility and applicability of the device. At the same time, the spring pre-tightening locking structure can ensure the connection strength and stability after adjustment, ensuring the safety and reliability of the testing process and reducing the limitations of the device during use.
