Description

Technical Field

[0001] This utility model relates to the field of defect detection technology, and in particular to a defect detection device for glass insulators. Background Technology

[0002] Glass insulators are common high-voltage insulation components in power systems, primarily used to support high-voltage power lines and ensure the reliability and safety of power transmission. The manufacturing process of glass insulators is complex and delicate, mainly including the following key steps: raw material preparation, melting and clarification, forming, annealing, and processing and cutting. Processing and cutting involves further processing and finishing of the insulator blanks. According to product design requirements, the insulator blanks undergo grinding, drilling, and lapping operations to meet the requirements of subsequent processes. Simultaneously, cutting equipment is used to cut the blanks to obtain insulator products of specific lengths and specifications. Precision and surface quality must be controlled during processing and cutting to ensure the performance and reliability of the final product.

[0003] Currently, most equipment for detecting defects in glass insulators is designed for finished products after the anchors and steel feet have been installed, rather than for insulator blanks. If the insulator blanks are not inspected beforehand, and inspection is only carried out after the anchors and steel feet have been installed, any defects (such as cracks, bubbles, stones, etc.) found in the glass insulator blanks will result in the waste of a lot of manpower and resources and an increase in production costs. Therefore, there is an urgent need to develop a defect detection device for glass insulators to quickly identify defective products in the insulator blanks. Utility Model Content

[0004] To address the technical problems mentioned in the background section, this utility model provides a glass insulator defect detection device.

[0005] This utility model discloses a defect detection device for glass insulators, comprising:

[0006] The conveyor belt is used to transport insulator blanks. The insulator blanks are transported to the material guiding assembly by a guide plate that is inclined at the feeding end.

[0007] The feeding assembly is used to perform multiple defect detections on the insulator blanks. It consists of a hopper, a feeding pipe, and a quality inspection module. The top opening of the hopper is used to receive the insulator blanks, and the bottom of the hopper is connected to the feeding pipe. The feeding pipe is L-shaped and consists of a vertical section and a horizontal section. The tail of the horizontal section is provided with a slowing section and a discharge section. The slowing section is equipped with a quality inspection module, and the tail of the discharge section is equipped with a material distribution mechanism.

[0008] The collection component is a collection box consisting of a good product compartment and a defective product compartment.

[0009] The return pipe, located between the collection box and the hopper, is used to re-inspect the insulator blanks in the defective product bin.

[0010] A support frame is installed above the opening of the hopper, and a soft buffer pad is provided on the inner wall of the hopper to further protect the insulator blank. A rotating shaft and a drive motor for driving the rotating shaft are rotatably installed on the support frame. A strip-shaped through hole for the insulator blank to pass through is opened on the rotating shaft. A receiving plate located behind the through hole is fixed on the rotating shaft. A waste collection hopper is provided behind the hopper. A limit plate is fixed on the front side of the through hole opening. The receiving plate is used to receive the insulator blank conveyed by the guide plate. The through hole opening is set to be flared to facilitate the entry of the insulator blank.

[0011] An electronic scale is mounted on the receiving plate. The electronic scale is electrically connected to the controller. The signal output terminal of the controller is electrically connected to the drive motor to control the forward and reverse rotation of the drive motor.

[0012] When the electronic scale detects that the weight of the insulator blank on the receiving plate is outside the set range, the controller controls the drive motor to reverse the receiving plate to the rear, so that the insulator blank on the receiving plate falls into the waste collection hopper.

[0013] When the electronic scale measures the weight of the insulator blank on the receiving plate to be within the set range, the controller controls the drive motor to rotate the receiving plate to a vertical position, so that the insulator blank on the receiving plate falls into the hopper through the through hole.

[0014] The quality inspection module is used to acquire images of the insulator blanks in the slow-speed section to determine whether there are defects in the insulator blanks. The quality inspection module includes a controller and a CCD detection module. The controller and the material distribution mechanism are electrically connected. Based on the judgment result of the CCD detection module, the controller transports the insulator blanks to different positions in the collection assembly through the material distribution mechanism.

[0015] The internal dimensions of the feeding pipe and return pipe are adapted to the size of the insulator blank, allowing the insulator blank to roll; the feeding pipe is L-shaped overall.

[0016] The material distribution mechanism includes a slide plate rotatably connected to the bottom of the discharge section port, a material distribution motor installed on the outside of the discharge section, a mounting shaft connected to the output end of the material distribution motor, a rocker arm one fixedly sleeved on the mounting shaft, and a rocker arm two movably sleeved on the mounting shaft; the bottom of the discharge section housing is provided with a notch, and a flipping bottom plate that flips to the left and right sides is rotatably set at the notch through a connecting shaft. A return torsion spring is installed on the connecting shaft. A crossbar located below the flipping bottom plate is fixed at the bottom end of the rocker arm one, and a stop bar is fixed on the crossbar. The end of the stop bar can abut against the flipping bottom plate. The material distribution mechanism also includes a valve unit linked to the mounting shaft and an adjustment unit that drives the rocker arm two to rotate synchronously with the rocker arm one.

[0017] The slide plate is rotatably connected to the bottom of the discharge section port via a connecting pin. The slide plate is connected to the end of the discharge section via a tension spring to facilitate the slide plate's reset. A hanging plate is fixed on the side of the slide plate near the discharge section. A hanging rod is provided at the end of the swing arm two, which is connected to the hanging plate and arranged perpendicular to the swing arm two. When the swing arm two rotates, it pulls the hanging plate through the hanging rod, thereby driving the slide plate to rotate.

[0018] The adjustment unit includes an end plate fixed to the end of the mounting shaft, an electromagnet one and an electromagnet two respectively mounted on the end plate and the adjacent side of the swing rod two, a plug rod fixed on the side of the swing rod two adjacent to the swing rod one, a slot that can be inserted into the swing rod one, and a return spring for driving the swing rod two to reset is also installed on the mounting shaft between the swing rod two and the swing rod one.

[0019] Electromagnet one and electromagnet two are connected to an external power source, which is electrically connected to a controller. The controller controls whether the power source is energized. When energized, the magnetic force drives the pendulum rod two to approach the pendulum rod one. When the insert rod and slot are inserted, the pendulum rod one and the pendulum rod two rotate synchronously.

[0020] The valve unit includes a mounting shaft, a gear plate, an intermediate gear, and a drive gear. The mounting shaft is provided on the side of the discharge section, and the drive gear is mounted on the mounting shaft. An intermediate gear that meshes with the drive gear is also installed on the side of the discharge section. One side of the intermediate gear meshes with the drive gear, and the other side meshes with one side of the gear plate. A blocking plate for sealing the discharge outlet of the discharge section is provided at the tail end of the discharge section, and the other side of the gear plate is connected to the blocking plate of the discharge section through multiple connecting rods.

[0021] While the drive gear rotates, it drives the toothed plate to move up and down through the intermediate gear, thereby realizing the opening and closing control of the discharge port of the discharge section by the blocking plate, so that the inspected insulator blanks can be pushed out from the discharge port.

[0022] When the quality inspection module detects that there are no defects in the insulator blank, the controller controls the material distribution motor to work, the valve unit opens, the flip plate rotates upward, and pushes the insulator blank through the slide plate into the good product bin;

[0023] When the quality inspection module detects a defect in the insulator blank, the controller controls the material distribution motor and the adjustment unit to work. At the same time, the valve unit opens, causing the second swing arm to rotate with the first swing arm, thereby driving the slide plate to rotate at a certain angle. At this time, the flip plate rotates upward, pushing the insulator blank through the slide plate into the defective product bin.

[0024] One end of the return pipe is connected to the hopper, and the other end of the return pipe is located in the defective product bin and is used to receive insulator blanks. The insulator blanks located in the defective product bin are conveyed upward to the hopper through the return pipe, and then undergo secondary testing through the conveying pipe below the hopper.

[0025] The defective product bin is equipped with a feeding mechanism that drives the movement of insulator blanks in the return pipe. The feeding mechanism includes a cut-off unit and a power unit. The power unit includes a push plate and a push rod. The defective product bin is equipped with a push plate that moves left and right along the tail end of the return pipe. The push plate is driven by a push rod installed on a partition. A compression pad that can extend into the return pipe is fixed to the side of the push plate near the return pipe. The push rod is an electric push rod or a hydraulic cylinder. A pressure sensor is installed at the bottom of the tail end of the return pipe and connected to a controller. The signal output terminal of the controller is electrically connected to the electric push rod or hydraulic cylinder. The cut-off unit includes a limit rod, a transmission gear one, and a transmission gear two. A linkage plate is installed at the bottom of the push plate. The linkage plate is equipped with meshing transmission gear one and transmission gear two. A limit rod that slides up and down through the housing is provided at the bottom of the tail end of the return pipe. The limit rod meshes with transmission gear two. The limit rod and the outer surface of the return pipe are connected by a spring.

[0026] A rotatable anti-slip plate is installed at the top of the inlet of the return pipe, and a spring connects the anti-slip plate to the outer surface of the return pipe.

[0027] Through the above-described solution, this utility model can remove a certain number of insulator blanks and then re-feed them to the hopper via a feeding mechanism, allowing the insulator blanks to be re-inspected by the quality inspection module, thereby improving the accuracy of the inspection.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] This utility model discloses a defect detection device for glass insulators, comprising a conveyor belt, a material guiding assembly, and a collection assembly. The conveyor belt is used to transport insulator blanks, and a guide plate is inclinedly arranged at the unloading end of the conveyor belt. The material guiding assembly includes a hopper, a conveying pipe, and a quality inspection module. The top of the hopper is open and used to receive the insulator blanks.

[0040] The present invention will now be further described in conjunction with 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.

[0041] Example 1: Refer to Figure 1 - Figure 8 The proposed solution provides a defect detection device for glass insulators, which includes a conveyor belt 1, a material guiding assembly, and a collection assembly.

[0042] Conveyor belt 1 is used to transport insulator blanks 2. A guide plate 3 is inclinedly installed at the unloading end of conveyor belt 1. A bracket 4 is fixed to the bottom of the guide plate 3, and the bottom end of the bracket 4 is connected to the hopper 9.

[0043] The material guiding assembly includes a hopper 9, a transparent conveying pipe 10, and a quality inspection module. The top of the hopper 9 is open and used to receive the insulator blank 2. The bottom of the hopper 9 is connected to the conveying pipe 10, which is L-shaped and allows the insulator blank 2 to roll inside. The horizontal section of the conveying pipe 10 has a slowing section 11 and a discharge section 13 at its tail. A material distribution mechanism 14 is installed at the tail of the discharge section 13. The conveying pipe 10 can be made of transparent resin. The width of the inner cavity of the conveying pipe 10 is slightly larger than the thickness of the insulator blank 2, and the insulator blank 2 is circular with a diameter slightly smaller than the length of the inner cavity of the conveying pipe 10 (the gap does not exceed 1 cm). This ensures that there will be no jamming inside the conveying pipe 10. The slowing section 11 is inclined, allowing the insulator blank 2 to move upward within it, thereby reducing the movement speed of the insulator blank 2 and facilitating its inspection.

[0044] The quality inspection module is used to acquire images of the insulator blank 2 in the slow section 11 to determine whether there are defects in the insulator blank 2. The quality inspection module includes a controller and a CCD detection module. The controller and the material distribution mechanism 14 are electrically connected. According to the judgment result of the CCD detection module, the controller transports the insulator blank 2 to different positions in the collection assembly through the material distribution mechanism 14.

[0045] The collection component includes a collection box 12, and an intermediate plate 22 is provided inside the collection box 12, which divides the collection box 12 into a good product compartment 18 and a defective product compartment 19.

[0046] This solution uses a CCD detection module to acquire multiple images of the insulator blank 2, determining whether defects such as cracks, bubbles, and stones exist. Based on the judgment information, a controller issues corresponding instructions to control the defective insulator blanks 2 to enter the defective product bin 19, while the other insulator blanks 2 enter the good product bin 18, and then proceed to the next process. The CCD detection module and controller proposed in this solution can use mature products currently available on the market, and the use of a CCD detection module for visual inspection to determine whether there are defects on the product surface is sufficiently clear to those skilled in the art, and will not be elaborated further here.

[0047] Please refer to Figure 1 and Figure 2A support frame 46 is installed above the opening of the hopper 9. The height of the support frame 46 should not be too high (not exceeding 30cm) to avoid damage caused by the insulator blank 2 falling from a height and impacting the inner wall of the hopper 9. In addition, a soft buffer pad can be provided on the inner wall of the hopper 9 to further protect the insulator blank 2. A rotating shaft 6 and a drive motor 7 for driving the rotating shaft 6 are rotatably mounted on the support frame 46. The rotating shaft 6 has a through hole 601 for the insulator blank 2 to pass through. A receiving plate 5 and a limiting plate 603 are also fixed on the rotating shaft 6. The receiving plate 5 and the limiting plate 603 are located on both sides of the through hole 601, and the receiving plate 5 is used to receive the insulator blank 2 conveyed by the guide plate 3. A flared opening 602 is provided on one side of the through hole 601 to facilitate the entry of the insulator blank 2.

[0048] The above solution can solve the problem that the insulator blanks 2 falling from the conveyor belt 1 cannot fall directly into the hopper 9, while also providing a certain buffering effect. Furthermore, the insulator blanks 2 can be smoothly fed into the hopper 9 by using the flipping of the receiving plate 5.

[0049] Furthermore, an electronic scale (not shown) is installed on the receiving plate 5. The electronic scale is electrically connected to the controller. The signal output terminal of the controller is electrically connected to the drive motor 7 to control the forward and reverse rotation of the drive motor 7. A waste collection hopper 45 is also installed on one side of the hopper 9. The drive motor 7 is powered by an external power source and can be a servo motor.

[0050] In this plan, refer to Figure 1 , Figure 4 The material distribution mechanism 14 includes a slide plate 16 rotatably connected to the bottom of the discharge section 13 port, a material distribution motor installed on the outside of the discharge section 13, a mounting shaft 44 connected to the output end of the material distribution motor, a rocker arm 28 fixedly sleeved on the mounting shaft 44, and a rocker arm 29 movably sleeved on the mounting shaft 44. The bottom of the discharge section 13 housing has a notch, and a flip-top plate 25 is rotatably installed at the notch via a connecting shaft. A reset torsion spring is installed on the connecting shaft. A crossbar 26 located below the flip-top plate 25 is fixed to the bottom end of the rocker arm 28. A stop bar 27 is fixed on the crossbar 26, and the end of the stop bar 27 can abut against the flip-top plate 25. The material distribution mechanism 14 also includes a valve unit linked to the mounting shaft 44 and an adjustment unit that drives the rocker arm 29 to rotate synchronously with the rocker arm 28.

[0051] Reference Figure 4 and Figure 6The adjustment unit includes an end plate 30 fixed to the end of the mounting shaft 44, and electromagnets 31 and 32 respectively mounted on the end plate 30 and adjacent to the swing arm 29. A plug rod 33 is fixed on the side of the swing arm 29 adjacent to the swing arm 28. A slot 34 is provided on the swing arm 28 that can be inserted into the plug rod 33. A return spring 52 for driving the swing arm 29 to reset is also installed on the mounting shaft 44 between the swing arm 29 and the swing arm 28. Electromagnets 31 and 32 are connected to an external power source, which is electrically connected to a controller. The controller controls whether the power source is energized. After being energized, the swing arm 29 can be driven to approach the swing arm 28 through magnetic force. When the plug rod 33 and the slot 34 are inserted, the swing arm 28 and the swing arm 29 can rotate synchronously.

[0052] The adjustment unit only operates when a defect is detected in the insulator blank 2, thereby changing the position of the slide plate 16 so that the insulator blank 2 can smoothly enter the defective product bin 19.

[0053] In specific work:

[0054] When the electronic scale measures that the weight of the insulator blank 2 on the receiving plate 5 is outside the set range, the controller controls the drive motor 7 to rotate, so that the insulator blank 2 on the receiving plate 5 falls into the waste collection hopper 45.

[0055] When the electronic scale measures the weight of the insulator blank 2 on the receiving plate 5 to be within the set range, the controller controls the drive motor 7 to rotate, so that the insulator blank 2 on the receiving plate 5 falls into the hopper 9 through the through hole 601.

[0056] Since the insulator blank 2 has defects, its weight will definitely differ from that of a good product. Based on this, the above structure is designed to perform preliminary screening of the insulator blank 2, thereby improving the efficiency and accuracy of the inspection.

[0057] When the quality inspection module detects that there are no defects in the insulator blank 2, the controller controls the material distribution motor to work, the valve unit opens, the flip base plate 25 rotates upward, and pushes the insulator blank 2 through the slide plate 16 into the good product bin 18.

[0058] When the quality inspection module detects a defect in the insulator blank 2, the controller controls the material distribution motor and the adjustment unit to work. At the same time, the valve unit opens, causing the second swing rod 29 to rotate with the first swing rod 28, thereby driving the slide plate 16 to rotate at a certain angle. At this time, the flipping base plate 25 rotates upward, pushing the insulator blank 2 through the slide plate 16 into the defective product bin 19.

[0059] In this design, the slide plate 16 is rotatably connected to the bottom of the discharge section 13 via a connecting pin. The outer side of the slide plate 16 and the outer surface of the discharge section 13 are also connected by a tension spring to facilitate the reset of the slide plate 16. A hanging plate 15 is fixed to the outer side of the slide plate 16. The end of the swing rod 29 is connected to a hanging rod that can work in conjunction with the hanging plate 15. The rotation of the swing rod 29 can drive the hanging rod to pull the hanging plate 15 and drive the slide plate 16 to rotate.

[0060] With the above scheme, when the quality inspection module detects a defect in the insulator blank 2, the adjustment unit can make the second swing rod 29 rotate with the first swing rod 28, and then use the hanging rod to pull the hanging plate 15 to drive the sliding plate 16 to rotate. At this time, the insulator blank 2 can fall into the defective product bin 19 through the sliding plate 16.

[0061] In an optional embodiment of this utility model, the valve unit includes a toothed plate 47 slidably connected to the outside of the discharge section 13, multiple connecting rods 48 connected to one side of the toothed plate 47, and a blocking plate 51 connected to the toothed plate 47 via the multiple connecting rods 48. An intermediate gear 49 is also installed on the outside of the discharge section 13, and a drive gear 24 meshing with the intermediate gear 49 is mounted on the mounting shaft 44. The blocking plate 51 is used to block the discharge port of the discharge section 13. This design allows for convenient and automatic opening of the discharge port of the discharge section 13, facilitating the ejection of the inspected insulator blank 2.

[0062] Example 2: This example is a further improvement on the above solution:

[0063] Reference Figure 1 and Figure 7 The proposed detection device also includes a secondary detection component, which comprises a return pipe 8. One port of the return pipe 8 is connected to the hopper 9, and the other port of the return pipe 8 is located in the defective product bin 19 and is used to receive the insulator blanks 2. This facilitates secondary detection of the collected insulator blanks 2, reduces detection errors, and improves accuracy.

[0064] The defective product bin 19 is also equipped with a feeding mechanism 21 that drives the movement of the insulator blanks 2 in the return pipe 8. The feeding mechanism 21 includes a stop unit and a power unit. The stop unit includes a limiting rod 40 that slides through the bottom shell of the return pipe 8, and a transmission gear 38 and a transmission gear 39 that are rotatably connected in the defective product bin 19. The transmission gear 38 and the transmission gear 39 mesh with each other. A rack 1 that can mesh with the transmission gear 39 is installed on the limiting rod 40. The limiting rod 40 and the outer surface of the return pipe 8 are connected by a spring. The power unit includes a push plate 3 that is movably installed in the defective product bin 19. 5. A linkage plate 37 connected to the push plate 35, on which a transmission gear 39 meshes with the first transmission gear 38 is mounted. A pressing pad 43, capable of extending into the return pipe 8, is fixed to the surface of the push plate 35. The power unit also includes a push rod 23 that drives the push plate 35. The push rod 23 can be an electric push rod or a hydraulic cylinder. A pressure sensor is installed at the bottom of the port of the return pipe 8 located on the side of the defective product bin 19 and connected to the controller. The signal output terminal of the controller is electrically connected to the electric push rod or hydraulic cylinder. After the pressure sensor outputs a signal, the controller controls the electric push rod or hydraulic cylinder to push. (Refer to...) Figure 1 The collection box 12 is equipped with a partition 17 and an intermediate plate 22 to house the push rod 23. The structure is compact and will not affect the collection of the insulator blank 2.

[0065] An anti-detachment plate 42 is rotatably installed on the top of the inlet 41 of the return pipe 8. A spring is connected between the anti-detachment plate 42 and the outer surface of the return pipe 8. The anti-detachment plate 42 can prevent the insulator blank 2 from being squeezed upwards during compression, thereby causing the secondary detection component to malfunction.

[0066] Through the above-described scheme, this utility model can remove a certain number of insulator blanks 2 and then re-feed the corresponding insulator blanks 2 back to the hopper 9 via the feeding mechanism 21. This allows the insulator blanks 2 to be re-inspected by the quality inspection module, thereby improving the inspection accuracy. In order to expel all the insulator blanks 2 from the return pipe 8 into the hopper 9, test pieces of the same size and specifications as the insulator blanks can be added to the return pipe 8 during operation. By gradually adding test pieces, all the insulator blanks 2 in the return pipe 8 can be gradually expelled for secondary inspection.

[0067] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
