Description

Technical Field

[0001] This invention relates to the field of porcelain insulator blank size detection technology, specifically an automated detection and sorting device for porcelain insulator blank size. Background Technology

[0002] Porcelain insulators play an important role in power systems, providing rigid support or suspension for live equipment and also serving as insulation protection. They possess excellent properties such as high temperature resistance, wear resistance, and corrosion resistance. Before putting porcelain insulators into use, the dimensions of the insulator blanks need to be inspected, and the diameter of the insulator blanks is detected by the operation of a laser rangefinder.

[0003] When inspecting porcelain insulators, since most porcelain insulators adopt an umbrella-shaped structure, the diameter of the porcelain insulator at different positions needs to be measured during the inspection process. However, because the porcelain insulator is clamped and limited by the fixture during the inspection process, the laser beam is very likely to shine on the surface of the fixture, which will affect the accuracy of the inspection data. At the same time, the fixture will also obstruct the laser beam when inspecting different positions of the porcelain insulator. Summary of the Invention

[0004] The purpose of this invention is to provide an automated detection and sorting device for the dimensions of porcelain insulator blanks in order to solve the problem of the inability to quickly detect the diameter at different positions of porcelain insulators.

The bottom of the C-shaped frame is rotatably connected to a second reciprocating screw extending to the inner side of the C-shaped frame via a bearing. A spur gear located below the C-shaped frame is installed at the bottom end of the second reciprocating screw. A threaded slider located inside the C-shaped frame is sleeved on the outer side of the second reciprocating screw.

A guide rod located between the telescopic cylinder and the second reciprocating screw is provided on the inner side of the C-shaped frame. The threaded slider is sleeved on the outer side of the guide rod. Racks are installed on both sides of the guide frame.

[0007] As a further embodiment of the present invention: the correction rotating component further includes a second transmission bevel gear installed on the outside of the transmission shaft, a micro motor is installed at the end of the push rod away from the transmission shaft, the output end of the micro motor is connected to a first transmission bevel gear meshing with the second transmission bevel gear, a second contact piece is installed on one side of the threaded slider, and a first contact piece located above the second contact piece is provided on the top side of the guide rod.

[0008] As a further aspect of the present invention: the vertical central axis of the rack is flush with the vertical central axis of the guide frame.

[0009] As a further aspect of the present invention: the second contact is electrically connected to an external power supply via a wire, and the first contact is electrically connected to a micro motor via a wire.

[0011] As a further embodiment of the present invention: the laser beam emitted by the laser rangefinder passes through the gap between two adjacent L-shaped limiting frames and irradiates the porcelain insulator blank.

[0012] As a further embodiment of the present invention: the ranging calibration component includes a second servo motor installed on one side of the bottom of the positioning plate a, the output end of the second servo motor is connected to a positioning plate b located on the other side of the positioning plate a, a positioning ring located outside the output shaft of the second servo motor is provided on the side of the positioning plate a near the positioning plate b, the outer wall of the positioning ring is rotatably connected to a collar through a bearing, a calibration plate is provided at the bottom of the collar, a counterweight is installed at the bottom end of the calibration plate, a second slot is provided on one side of the calibration plate, a stop rod is provided on the outer wall of the collar located on one side of the calibration plate, a first slot is provided on one side of the stop rod, and a shift pin extending to the inner side of the second slot is provided on the positioning plate b.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a correction rotating component, the first servo motor drives the first reciprocating screw to rotate, causing the T-shaped slider to move to the middle position of the guide frame. This allows the guide roller to clamp and limit the porcelain insulator blank, aligning the center of the porcelain insulator blank with the center of the tray. At this time, the rotation of the spur gear compresses the telescopic spring, causing the second contact piece to contact the first contact piece. By energizing the micro motor, the first transmission bevel gear drives the transmission shaft to rotate through the second transmission bevel gear. The rotation of the transmission shaft causes the guide roller to rotate the porcelain insulator blank, thus realizing the rotation and reversal of the porcelain insulator. When the laser rangefinder detects the horizontal height of a point on the porcelain insulator blank, if the detection data changes significantly, it indicates that the edge of the porcelain insulator is not circular. This allows for the determination of whether the porcelain insulator is qualified, thus enabling rapid detection of different positions on the porcelain insulator blank. 2. By setting up a ranging calibration component, the laser rangefinder is activated before testing the porcelain insulator blank. The laser beam emitted by the laser rangefinder illuminates one end of the positioning plate b. Then, the second servo motor is activated, causing the positioning plate b to rotate 90 degrees. This rotation of the positioning plate b by the second servo motor moves the shift pin out of the second slot. When the positioning plate b rotates 45 degrees, the shift pin engages in the first slot. At this time, the laser beam emitted by the laser rangefinder illuminates one end of the calibration plate, and the data detected by the laser rangefinder will change. When the difference in the data detected by the laser rangefinder changes by 10 centimeters, it indicates that the data detected by the laser rangefinder is accurate. The positioning plate b continues to rotate, and the shift pin drives the stop rod to rotate through the first slot, thereby misaligning the calibration plate with the laser rangefinder. This calibrates the laser rangefinder and further improves the accuracy of fatigue detection data for porcelain insulators. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0020] Please see Figures 1 to 8In this embodiment of the invention, an automated detection and sorting device for the size of porcelain insulator blanks includes a positioning frame 1, a controller 2 installed on the top of the positioning frame 1, a guide frame 3 installed on the bottom inner side of the positioning frame 1, a first servo motor 4 connected to one end of the guide frame 3, a first reciprocating screw 23 located inside the guide frame 3 connected to the output end of the first servo motor 4, a T-shaped slider 21 slidably connected to the guide frame 3 sleeved on the outer side of the first reciprocating screw 23, a correction rotating component provided on the T-shaped slider 21, a linear module 5 located on one side of the guide frame 3 installed on the inner side of the positioning frame 1, a laser rangefinder 6 installed on the linear module 5, a positioning plate a35 flush with the linear module 5 installed on one side of the positioning frame 1, and a distance calibration component installed at the bottom end of the positioning plate a35. The correction rotating component includes a tray 10 mounted on top of the T-shaped slider 21 and located above the guide frame 3. An L-shaped limiting frame 11 is provided on the outer side of the tray 10, and a support frame 13 is mounted on the top of the L-shaped limiting frame 11. C-shaped clamping frames 27 are fixedly connected to both sides of the T-shaped slider 21. A telescopic cylinder 20 is provided on the inner side of the C-shaped clamping frame 27. A connecting frame 19 is connected to the output end of the telescopic cylinder 20. A conveyor 16 is provided on the top of the connecting frame 19.

[0021] In this embodiment, when testing the porcelain insulator, one end of the porcelain insulator is first attached to the top of the tray 10. Then, the calibration rotation mechanism is activated to fix the porcelain insulator to the top of the tray 10. Next, the laser rangefinder 6 and the ranging calibration mechanism are activated to test the accuracy of the data measured by the laser rangefinder 6. Then, the first servo motor 4 is activated to move the T-shaped slider 21 to the center position of the guide frame 3. At this time, the operation of the calibration rotation mechanism limits the porcelain insulator on the top of the tray 10, and the porcelain insulator rotates. The laser beam emitted by the laser rangefinder 6 will then irradiate the surface of the porcelain insulator. Since the distance between the laser rangefinder 6 and the central axis of the guide frame 3 is fixed, and the operation of the calibration rotation mechanism ensures that the central axis of the porcelain insulator is located at the center of the T-shaped slider 21, the process is as follows: In this way, the diameter of the porcelain insulator can be calculated by the controller 2. Then, the laser rangefinder 6 is moved vertically by the linear module 5, so that the diameter at different positions of the porcelain insulator can be detected. The detection data is used to determine whether the porcelain insulator is qualified. Then, the first servo motor 4 is started. The first servo motor 4 drives the rotation of the first reciprocating screw 23 to move the T-shaped slider 21 to the end of the guide frame 3 away from the first servo motor 4. At this time, the porcelain insulator loses its limit. Then, the telescopic cylinder 20 is started. The extension of the telescopic cylinder 20 causes the conveyor 16 to move the porcelain insulator upward. If the detected insulator blank is qualified, the conveyor 16 moves the porcelain insulator blank to the left. If the detected insulator blank is unqualified, the conveyor 16 moves the porcelain insulator blank to the left under the operation of the controller 2, thereby realizing the distribution of the porcelain insulator blank.

[0022] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6The correcting rotating component includes a sleeve 31 inserted into the top of the C-shaped frame 27. A second reciprocating screw 29 extending into the inner side of the C-shaped frame 27 is rotatably connected to the bottom of the C-shaped frame 27 via a bearing. A spur gear 28 located below the C-shaped frame 27 is mounted at the bottom end of the second reciprocating screw 29. A threaded slider 34 located inside the C-shaped frame 27 is sleeved on the outer side of the second reciprocating screw 29. A telescopic spring 30 connected to the bottom of the sleeve 31 is provided at the top of the threaded slider 34. A connecting ring 32 is mounted at the top of the sleeve 31. The top of the ring 32 is rotatably connected to the inclined frame 33 via a rotating shaft. The top of the inclined frame 33 is rotatably connected to the push rod 12 via a rotating shaft. The push rod 12 passes through the L-shaped limit frame 11. The end of the push rod 12 away from the inclined frame 33 is rotatably connected to the drive shaft 15 via a bearing. The top of the drive shaft 15 is equipped with a guide roller 18. The inner side of the C-shaped frame 27 is provided with a guide rod 26 located between the telescopic cylinder 20 and the second reciprocating screw 29. The threaded slider 34 is sleeved on the outer side of the guide rod 26. The guide frame 3 is equipped with racks 7 on both sides. The correcting rotating component also includes a second transmission bevel gear 17 mounted on the outside of the transmission shaft 15, a micro motor 22 mounted on the end of the push rod 12 away from the transmission shaft 15, the output end of the micro motor 22 is connected to a first transmission bevel gear 14 that meshes with the second transmission bevel gear 17, a second contact piece 25 is mounted on one side of the threaded slider 34, and a first contact piece 24 located above the second contact piece 25 is provided on the top side of the guide rod 26.

[0023] Among them, the vertical central axis of the rack 7 is flush with the vertical central axis of the guide frame 3, the second contact piece 25 is electrically connected to the external power supply through the wire, the first contact piece 24 is electrically connected to the micro motor 22 through the wire, and four L-shaped limit frames 11 are provided, and the four L-shaped limit frames 11 are evenly distributed along the center of the tray 10. The laser beam emitted by the laser rangefinder 6 passes through the gap between two adjacent L-shaped limit frames 11 and irradiates the porcelain insulator blank.

[0024] In this embodiment, the first servo motor 4 is started, which drives the rotation of the first reciprocating screw 23 to move the T-shaped slider 21 to the middle position of the guide frame 3. During this process, the spur gear 28 meshes with the rack 7. At this time, the spur gear 28 will rotate as it moves with the C-shaped clamp frame 27, thereby causing the second reciprocating screw 29 to rotate. At this time, the threaded slider 34, which is limited by the guide rod 26, will move upward along the second reciprocating screw 29. In this way, the sleeve block 31 can be pushed upward by the telescopic spring 30. At this time, the connecting ring 32 will push the push rod 12 towards the center of the tray 10 by squeezing the inclined connecting frame 33. In this way, the guide roller 18 can clamp and limit the porcelain insulator blank, thereby making the porcelain insulator... When the center of the insulator blank is aligned with the center of the tray 10, the rotation of the spur gear 28 causes the telescopic spring 30 to be compressed, thereby causing the second contact piece 25 to contact the first contact piece 24, which in turn energizes the micro motor 22. With the energization of the micro motor 22, the first transmission bevel gear 14 drives the transmission shaft 15 to rotate through the second transmission bevel gear 17. The rotation of the transmission shaft 15 causes the guide roller 18 to rotate the porcelain insulator blank, thus realizing the rotation and reversal of the porcelain insulator. When the laser rangefinder 6 detects the horizontal height of a point on the porcelain insulator blank, if there is a large change in the detection data, it indicates that the edge of the porcelain insulator is not circular, thus determining whether the porcelain insulator is qualified.

[0025] Please refer to this carefully. Figure 1 , Figure 7 , Figure 8 The ranging calibration component includes a second servo motor 9 installed on one side of the bottom of the positioning plate a35. The output end of the second servo motor 9 is connected to a positioning plate b35 located on the other side of the positioning plate a35. A positioning ring 36 located outside the output shaft of the second servo motor 9 is provided on the side of the positioning plate a35 near the positioning plate b35. A collar 37 is rotatably connected to the outer wall of the positioning ring 36 through a bearing. A calibration plate 40 is provided at the bottom of the collar 37. A counterweight 43 is installed at the bottom end of the calibration plate 40. A second slot 41 is provided on one side of the calibration plate 40. A stop rod 38 located on one side of the calibration plate 40 is provided on the outer wall of the collar 37. A first slot 39 is provided on one side of the stop rod 38. A shift pin 42 extending to the inside of the second slot 41 is provided on the positioning plate b35.

[0026] The included angle between the calibration plate 40 and the stop rod 38 is 45 degrees, the distance between the calibration plate 40 and the positioning plate b35 is 10 centimeters, the opening of the first slot 39 faces the calibration plate 40, and the opening of the second slot 41 faces the stop rod 38.

[0027] In this embodiment, before inspecting the porcelain insulator blank, the laser rangefinder 6 is activated so that the laser beam emitted by the laser rangefinder 6 illuminates one end of the positioning plate b35. Then, the second servo motor 9 is activated, causing the positioning plate b35 to rotate 90 degrees. The rotation of the positioning plate b35 by the second servo motor 9 causes the shift pin 42 to move out of the second slot 41. When the positioning plate b35 rotates 45 degrees, the shift pin 42 engages in the first slot 39. At this time, the laser beam emitted by the laser rangefinder 6... The beam will then shine on one end of the calibration plate 40. At this time, the data detected by the laser rangefinder 6 will change. When the difference in the data detected by the laser rangefinder 6 changes to ten centimeters, it indicates that the data detected by the laser rangefinder 6 is accurate. The positioning plate b35 continues to rotate, and the shift pin 42 will drive the stop rod 38 to rotate through the first slot 39, thereby causing the calibration plate 40 and the laser rangefinder 6 to be misaligned. In this way, the laser rangefinder 6 can be calibrated, further improving the accuracy of fatigue detection data of porcelain insulators.
