Abstract
Description
Technical Field
[0001] This invention relates to the field of capacitor high-voltage testing technology, and specifically to an automatic capacitor wiring high-voltage testing device. Background Technology
[0002] In the high-voltage and partial discharge testing process of capacitors before they leave the factory, most of the bolting and connection work for the multi-terminal terminals of the capacitors is done manually. Manual operation is labor-intensive and inefficient, and it is difficult to adapt to the production rhythm of automated production lines. Manual tightening cannot stably control the torque, which can easily lead to problems such as loose connections, excessive contact resistance, or stripped screw holes. The hole alignment is also difficult, which directly reduces the reliability of the high-voltage test results. At the same time, in the high-voltage testing environment of 15kV level, there is a risk of electric shock for personnel working at close range, and the strong electromagnetic field of high voltage can also cause electromagnetic interference to surrounding devices.
[0003] A high-voltage ceramic capacitor testing device, with announcement number CN206818833U, includes a test oil box, a test fixture, and a withstand voltage tester. The test oil box is a sealed container with an opening at the top, and the container contains insulating oil. The test fixture includes electrode clamps and electrode lead-out posts fixed on an insulating plate. The electrode clamps are used to insert the lead-out electrodes of the high-voltage ceramic capacitor and lead them out through wires to the electrode lead-out posts.
[0004] Traditional capacitor testing devices cannot perform automatic high-voltage testing on the capacitor body. Manual operation is not only labor-intensive and slow, but also difficult to match the continuous production needs of assembly lines. The torque of manually tightening bolts is difficult to control, which can easily lead to loose connections or damaged screw holes, directly affecting the accuracy of high-voltage testing and partial discharge detection results. Summary of the Invention

[0012] Preferably, the output slider of the first linear drive module is provided with an upper pressure plate, the partial discharge coupling plate is provided with a lower support plate corresponding to the upper pressure plate, and a pressure sensor is provided between the lower support plate and the upper pressure plate.
[0013] Preferably, the screw tightening structure includes two servo side plates arranged opposite each other. One of the servo side plates is connected to the partial discharge coupling plate through a second insulator. Between the two servo side plates, there are several studs for threaded connection with the screw holes on the terminal blocks. Each stud is provided with a drive structure for driving it to move up and down and rotate. The servo side plates are provided with two opposite terminal blocks. The terminal blocks are provided with several electrode plates. Each electrode plate corresponds to a stud, and the electrode plate is provided with a through hole for the stud to pass through.
[0014] Preferably, the drive structure includes a second cylinder fixedly mounted on the servo side plate. The push rod of the second cylinder faces downward and is connected to a shield. A servo motor is installed inside the shield. The output shaft of the servo motor faces downward and is connected to a stud via a torque plate.
[0015] Preferably, the test assembly includes two sets of adjacent test components. Each test component includes a test area transfer roller structure, a lifting mechanism, and a screw tightening structure. The two sets of test components share a high-voltage tester. The high-voltage tester is equipped with a conversion circuit, which is used to selectively connect one set of test components to the high-voltage tester.

[0018] 3. Each stud is equipped with an independent servo motor and torque plate, which can automatically complete the tightening and unwinding of capacitor terminal bolts. The tightening torque can be monitored in real time, which can avoid insufficient torque causing loose connections and excessive contact resistance, and prevent excessive torque from causing stripping and damage to the screw holes. The shield can reduce the interference of high voltage and strong electromagnetic field on the servo motor and ensure the stable operation of the drive mechanism.
[0019] 4. Two sets of test components share one high-voltage tester. The test circuit is switched by a conversion circuit. While one set is performing the test operation, the other set can complete the workpiece loading and unloading and wiring preparation work, which greatly reduces the standby idle time of the high-voltage tester, improves the utilization rate of the high-voltage tester equipment, and increases the overall test production cycle.

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] See Figures 1-10 As shown, the present invention provides an automatic capacitor wiring high voltage testing device, including a test area transmission roller structure 1. The test area transmission roller structure 1 has inlet and outlet transmission roller structures 2 at both ends along the transmission direction to the capacitor body 7. The test area transmission roller structure 1 is provided with two sets of capacitor positioning mechanisms 3 for positioning and clamping the capacitor body 7. A screw tightening structure 6 for tightening the wiring of the capacitor body 7 is provided on one side of the test area transmission roller structure 1. A lifting mechanism 5 for adjusting the screw tightening structure 6 up and down is provided on one side of the test area transmission roller structure 1.
[0029] In some embodiments, the capacitor body 7 to be tested is conveyed into the test area transfer roller structure 1 by the inlet / outlet transfer roller structure 2 on one side. When the capacitor body 7 arrives at the test area transfer roller structure 1, the two sets of capacitor positioning mechanisms 3 arranged on the test area transfer roller structure 1 simultaneously perform clamping actions, completing the positioning and clamping from both sides of the capacitor body 7, constraining the horizontal position of the capacitor body 7, preventing the capacitor body 7 from shifting horizontally, and ensuring that the top terminal of the capacitor body 7 is aligned with the tightening head of the screw tightening structure 6 above. A lifting mechanism 5 is arranged on the side of the test area transfer roller structure 1. The lifting mechanism 5 drives the screw tightening structure 6 to move up and down as a whole. When moving downward, the screw tightening structure 6 moves closer to the capacitor body 7, and the screw tightening structure 6 performs the tightening action of the stud 607 and the screw hole 702, completing the wiring compression between the screw and the capacitor body 7, establishing the electrical connection required for high voltage testing and ensuring a stable connection. After the test wiring is completed, the screw tightening structure 6 is released, and the lifting mechanism 5 drives the screw tightening structure 6 to lift upward and reset. After the capacitor body 7 has been tested, it is then sent out of the test station via the feed and discharge conveyor roller structure 2 on the other side.
[0030] In some embodiments, the capacitor body 7 to be tested is conveyed into the test area transfer roller structure 1 by the feed and discharge transfer roller structure 2 on one side; when the capacitor body 7 arrives on the test area transfer roller structure 1 at the test station, the two sets of capacitor positioning mechanisms 3 arranged on the test area transfer roller structure 1 perform clamping actions simultaneously, and complete the positioning clamping from both sides of the capacitor body 7, constraining the horizontal position of the capacitor body 7, avoiding horizontal positional displacement of the capacitor body 7, and ensuring that the top terminal of the capacitor body 7 is aligned with the tightening head of the screw tightening structure 6 above.
[0031] In this embodiment, the test area conveyor roller structure 1 and the two infeed / outfeed conveyor roller structures 2 are mutually insulated, with an insulation interval greater than 50mm. Furthermore, each roller conveyor, especially the test area conveyor roller structure 1, uses insulators as support bases to insulate it from the ground. Each roller conveyor line is insulated from the ground, and the insulation strength can withstand a voltage of 15kV.
[0032] In some embodiments, such as Figure 1 and Figure 3 As shown, the test area transmission roller structure 1 includes a roller conveyor 101 arranged vertically and a base 102, with several first insulators 103 disposed between the roller conveyor 101 and the base 102. Through the above-described structural design, when the equipment conducts a high-voltage withstand voltage test on the capacitor, a high-voltage potential is applied to the roller conveyor 101 side. The first insulators 103 can block the high voltage from being conducted to the base 102 and the equipment ground side, ensuring that the test area transmission roller structure 1 has the insulation performance to meet the requirements of the high-voltage test, avoiding high-voltage short circuits to ground and leakage problems, and ensuring the safety and reliability of the high-voltage test process.
[0033] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the feed and discharge conveyor roller structure 2 is provided with two guide structures 4 arranged opposite to each other. The two guide structures 4 extend along the conveying direction of the feed and discharge conveyor roller structure 2 as a whole, covering most of the conveying stroke of the feed and discharge conveyor roller structure 2. The two are directly opposite each other in the lateral direction, forming a guide channel for the capacitor body 7 to pass through. In this embodiment, the guide structure 4 is further defined as follows: the guide structure 4 includes a side frame 401, and a guide rod structure is movably provided on the side frame 401. The guide rod structure includes a sleeve 402, which is slidably sleeved on the vertical frame rod of the side frame 401. An adjusting bolt 404 for tightening and fixing the vertical frame rod is threaded on the sleeve 402. A support lug 405 is provided on one side of the sleeve 402, and an adjusting rod 403 is slidably provided through the support lug 405. A guide plate 406 is fixedly connected to the end of the adjusting rod 403, and an adjusting bolt 404 for tightening and fixing the adjusting rod 403 is threaded on the support lug 405. Through the above-described structural design, the sleeve 402 can slide up and down along the side frame 401 to adjust the guide height. Loosening the adjusting bolt 404 allows the adjusting rod 403 to move laterally, changing the distance between the two guide plates 406 to accommodate capacitors of different widths. After the position is adjusted, tightening the adjusting bolt 404 locks the adjusting rod 403 in place. Through vertical adjustment of the sleeve 402 and horizontal adjustment of the adjusting rod 403, the guide plate 406 can accommodate capacitor bodies 7 of various shapes and sizes, providing guidance and correction during transport to prevent capacitor deviation.
[0034] For example, guide plate 406 uses a non-metallic soft guide rod, such as nylon, to ensure that the product does not tip over or get scratched during transport.
[0035] In some embodiments, such as Figure 1 , Figure 2 and Figure 8As shown, the capacitor positioning mechanism 3 is mounted and fixed on the base 102 of the test area transfer roller structure 1. The capacitor positioning mechanism 3 includes a frame 301, on which a first cylinder 302 is fixedly mounted. The first cylinder 302 is arranged along the width direction of the test area transfer roller structure 1, and the push rod of the first cylinder 302 extends towards the side of the test area transfer roller structure 1. The head end of the push rod of the first cylinder 302 is connected to the positioning clamp 303, and the positioning clamp 303 is driven by the first cylinder 302 to perform lateral telescopic movement. Guide wheels 304 are rotatably mounted at both ends of the positioning clamp 303, and the guide wheels 304 can rotate freely. When the capacitor body 7 is delivered to the position, the first cylinders 302 on both sides extend synchronously, driving the positioning clamps 303 on both sides to move towards the capacitor body 7. During the clamping contact process, the guide wheels 304 at both ends of the positioning clamp 303 preferentially contact the side wall of the capacitor body 7. The guide wheels 304 roll against the surface of the capacitor shell, transforming the sliding friction between the positioning clamp 303 and the capacitor body 7 into rolling friction. This can achieve offset positioning of the capacitor body 7 and buffer the impact at the moment of clamping contact, thereby reducing the risk of scratching or bumping the paint surface of the capacitor shell during the clamping process.
[0036] In some embodiments, the lifting mechanism 5 is further defined as follows: the lifting mechanism 5 includes two columns 501 arranged opposite each other, which constitute the main support frame of the lifting mechanism 5 and are arranged on both sides of the sliding motion path. Each column 501 is equipped with a slide rail 508 on the side wall facing the test area transmission roller structure 1. The two slide rails 508 are parallel to each other and arranged vertically. The two sides of the partial discharge coupling plate 506 are respectively slidably engaged with the slide rails 508 on the corresponding sides, so that the partial discharge coupling plate 506 can slide smoothly up and down along the slide rails 508 between the two columns 501. The screw tightening structure 6 is assembled and fixed on the partial discharge coupling plate 506 through the second insulator 8 and moves up and down synchronously with the partial discharge coupling plate 506.
[0037] A first linear drive module 502 is assembled between the two columns 501. The first linear drive module 502 serves as a power source, and its output slider can perform vertical linear motion to drive the partial discharge coupling plate 506 to complete the lifting and lowering displacement along the slide rail 508. A limit block 507 is connected across the upper end of the two columns 501. The limit block 507 is arranged on the maximum upward stroke path of the partial discharge coupling plate 506, serving as a mechanical hard limit. When the partial discharge coupling plate 506 moves upward to the preset highest position, the partial discharge coupling plate 506 abuts against the limit block 507, restricting the partial discharge coupling plate 506 from continuing to move upward. A limit switch can also be installed at this position to prevent the first linear drive module 502 from overtraveling, providing mechanical protection and preventing module overload and collision damage to mechanical components.
[0038] An upper pressure plate 505 is fixedly installed on the output slider of the first linear drive module 502. A lower support plate 503 is provided on the side of the partial discharge coupling plate 506 facing the slider, which is directly opposite the upper pressure plate 505. The pressure sensor 504 is clamped and arranged between the upper pressure plate 505 and the lower support plate 503.
[0039] During the operation of the mechanism, the output slider of the first linear drive module 502 outputs driving force downward. The driving force is transmitted to the lower support plate 503 through the upper pressure plate 505 and the pressure sensor 504 in sequence, thereby driving the partial discharge coupling plate 506 and the screw tightening structure 6 on it to move downward together towards the capacitor body 7.
[0040] The partial discharge coupling plate 506 also serves as a carrier for partial discharge signal acquisition. During high-voltage testing, it can couple and acquire partial discharge signals to cooperate with the back-end testing system to complete the partial discharge detection of the capacitor. When the first linear drive module 502 drives the slider to retract upward, it lifts the partial discharge coupling plate 506, completing the reset action after the test. When it moves to the limit position, it is mechanically stopped by the limit block 507.
[0041] Based on the aforementioned embodiments, this embodiment further defines the screw tightening structure 6, such as... Figure 2 , Figure 6 , Figure 7 , Figure 9 As shown, the screw tightening structure 6 moves up and down together with the partial discharge coupling plate 506 to complete the automatic threaded locking connection with the terminal 701 of the capacitor body 7. The screw tightening structure 6 includes two servo side plates 601 arranged opposite each other. One of the servo side plates 601 is connected to the partial discharge coupling plate 506 via the second insulator 8. The second insulator 8 mechanically bears the overall load of the screw tightening structure 6, and at the same time realizes the electrical isolation between the screw tightening structure 6 and the partial discharge coupling plate 506, avoiding crosstalk between high voltage test potentials and ensuring that the partial discharge signal acquisition is not affected by the high voltage wiring circuit.
[0042] Multiple studs 607 are arranged between the two servo side plates 601. Each stud 607 corresponds to a terminal 701 on the capacitor body 7 and a screw hole 702 on the terminal. When the stud 607 moves downward, it can form a threaded engagement with the screw hole 702 to achieve electrical conduction. Each stud 607 is equipped with an independent drive structure, and each drive structure can independently complete the lifting, feeding, and rotating tightening actions of the corresponding stud 607.
[0043] Two servo side plates 601 are also equipped with terminal blocks 602 facing each other, forming an installation space between the two sets of terminal blocks 602; several electrode plates 603 are fixed on the terminal blocks 602, and the electrode plates 603 and studs 607 are set one-to-one. Each electrode plate 603 has a through hole 606, and the stud 607 can pass through the through hole 606. When the stud 607 is tightened downwards and connected to the screw hole 702 of the terminal block 701, the stud 607 rod makes contact with the electrode plate 603 and conducts electricity. The high-voltage test cable is connected to the terminal block 602, thereby connecting the high-voltage test circuit to the terminal block 701 of the capacitor body 7 through the electrode plate 603, establishing the electrical path required for high-voltage testing. The drive structure includes a second cylinder 605, which is fixedly installed on the servo side plate 601. The push rod of the second cylinder 605 is arranged downwards, and the end of the push rod is connected to the shield 604. The servo motor 609 is installed inside the shield 604. The shield 604 plays an electromagnetic shielding role, weakening the interference of the strong electromagnetic field generated by the high-voltage test on the operation of the servo motor 609, and ensuring the stable and reliable motor drive control. The output shaft of the servo motor 609 faces downwards, and the output shaft is connected to the stud 607 via a torque disk 608. The torque disk 608 can provide real-time feedback on the tightening torque, realize torque monitoring, prevent the stud 607 from being damaged by excessive tightening torque, which could cause the threaded hole 702 to strip. It can also avoid problems such as high contact resistance and loose wiring caused by insufficient torque.
[0044] The automatic capacitor wiring high voltage test device includes two sets of adjacent test components. Each test component includes at least a test area transmission roller structure 1, a lifting mechanism 5, and a screw tightening structure 6. The two sets of test components share a high voltage tester. The high voltage tester is equipped with a conversion circuit, which is used to selectively connect one set of test components to the high voltage tester.
[0045] For example, as shown in the appendix to the specification. Figure 9 As shown, the test assembly includes a test area conveyor roller structure 1, an infeed and outfeed conveyor roller structure 2, a lifting mechanism 5, and a screw tightening structure 6. Each test assembly is equipped with an independent infeed and outfeed conveyor roller structure 2. For example, as shown in the appendix to the specification. Figure 10 As shown, the two test components share the feed and discharge conveyor roller structure 2. The feed and discharge conveyor roller structure 2 can switch positions between the two test components. Driven by the second linear drive module 9 and supported by the moving wheel 10, the feed and discharge conveyor roller structure 2 moves to supply parts and discharge materials to the two test components respectively.
