Description

Technical Field

[0001] This utility model relates to the field of capacitor withstand voltage testing technology, specifically to a high-voltage capacitor withstand voltage testing conveying mechanism. Background Technology

[0002] In the production and use of high-voltage foil capacitors, the withstand voltage test is a crucial step. This test can evaluate the insulation strength and stability of the capacitor under high voltage, ensuring its safe and reliable operation in practical applications. With the advancement of technology and the increasing demand for electrical equipment, the requirements for the efficiency, accuracy and automation of high-voltage capacitor withstand voltage testing are also becoming increasingly stringent.

[0003] In withstand voltage testing, since stray capacitance cannot be fully charged, there will be no instantaneous inrush current. There is no need to allow the test voltage to rise slowly; the full voltage can be applied at the beginning of the test, which simplifies the testing process and improves testing efficiency.

[0004] However, traditional high-voltage capacitor withstand voltage testing relies on manual operation and testing individual capacitors one by one, which is easily affected by human factors, making it difficult to guarantee the accuracy of the test results. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-voltage capacitor withstand voltage test conveying mechanism, which can effectively solve the problem that the withstand voltage test of high-voltage capacitors is easily affected by human factors, making it difficult to guarantee the accuracy of the test results.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a high-voltage capacitor withstand voltage test conveying mechanism, comprising a base, a conveyor belt fixedly installed on the top of the base for transporting capacitor cores, photoelectric sensors fixedly installed at both ends of the conveyor belt, an upper plate fixedly installed on the base via support columns, a lifting mechanism provided on the upper plate, the lifting mechanism including a servo motor fixedly installed on the upper plate, the output shaft of the servo motor being connected to a worm gear via a transmission mechanism, the worm gear meshing with a worm wheel, a threaded rod internally connected to the worm wheel, one end of the threaded rod being fixedly installed on a limiting plate, the other end being fixedly installed on a flattening cylinder, a pressure plate and an insulating pressure plate being fixedly installed on the output shaft of the flattening cylinder, the limiting plate being slidably connected to a first guide rod, and a core receiving mechanism provided at the end of the conveyor belt.

[0008] Furthermore, the transmission mechanism includes a first synchronous pulley fixedly mounted on the output shaft of the servo motor, a second synchronous pulley connected to the first synchronous pulley via a first synchronous belt, the second synchronous pulley fixedly mounted on a worm gear, the worm gear rotatably mounted on a connecting member, the worm wheel rotatably mounted on the connecting member, and the connecting member fixedly mounted on the upper top plate.

[0009] Furthermore, the core receiving mechanism includes a rodless cylinder fixedly mounted on the conveyor belt, and a baffle is fixedly mounted on the output shaft of the rodless cylinder. The baffle is used to push the capacitor core onto the core receiving plate. The core receiving plate is fixedly mounted on a swing plate, and the swing plate is rotatably mounted on a fixed plate.

[0010] Furthermore, the lower part of the swing plate is in contact with the fixed seat, the fixed seat is fixedly connected to the output shaft of the swing cylinder, and the swing cylinder is fixedly mounted on the base plate of the frame.

[0011] Furthermore, the fixed plate is slidably connected to a lifting core support plate, the back of the lifting core support plate is fixed with a slider, the slider is threadedly connected to a ball screw, the slider is slidably connected to a second guide rod, the ball screw is rotatably installed inside the fixed plate, and the second guide rod is fixedly installed inside the fixed plate.

[0012] Furthermore, the ball screw is fixedly mounted with a third synchronous pulley, the third synchronous pulley is connected to a fourth synchronous pulley via a second synchronous belt, the fourth synchronous pulley is fixedly mounted with a reducer, and the reducer is fixedly mounted with a drive motor.

[0013] Furthermore, the fixing plate is fixedly installed on the frame base plate, the frame base plate is fixedly installed with an insulating base, and a base is fixedly installed on top of the insulating base.

[0014] Furthermore, the photoelectric sensor is fixedly mounted on the sensor mounting base, one end of the support column is fixedly mounted on the base, the other end of the support column is fixedly mounted on the top plate, the first guide rod is fixedly mounted on the top plate, and a stop block is fixedly mounted on the top of the first guide rod.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The high-voltage capacitor withstand voltage test conveying mechanism proposed in this utility model achieves precise lifting and lowering control of the flattening cylinder and its connected insulating pressure plate by adopting a servo motor-driven worm gear and worm wheel transmission system. This design not only improves the automation level of the capacitor core withstand voltage test, but also ensures the accuracy and stability of the pressure during the test. At the same time, due to the self-locking characteristics of the worm gear and worm wheel transmission, the current position can be maintained even in the event of a power failure, thereby enhancing the safety and reliability of the equipment. In addition, the precise positioning of the capacitor core by photoelectric sensors realizes automatic conveying and positioning, further improving the testing efficiency.

[0017] 2. The high-voltage capacitor withstand voltage test conveying mechanism of this utility model also cleverly incorporates a core-receiving mechanism. Through the combined use of a rodless cylinder and a swing cylinder, it achieves automatic collection and conveying of the capacitor cores after the test is passed. At the same time, the design of the lifting core-receiving tray allows the capacitor cores to be stacked in an orderly manner, facilitating subsequent sorting and transfer. Furthermore, the lifting motion of the core-receiving tray is driven by a ball screw, featuring smooth movement and accurate positioning, ensuring the stability and safety of the capacitor cores during conveying and stacking. More importantly, the slider is limited by the second guide rod, preventing the lifting core-receiving tray from rotating during the lifting process, further ensuring the stability and reliability of the equipment.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] A high-voltage capacitor withstand voltage test conveying mechanism, as shown in the attached figure. Figures 1-4 The system includes a base 1, a conveyor belt 2 fixedly mounted on top of the base 1, the conveyor belt 2 being used to transport capacitor cores 39, photoelectric sensors 3 fixedly mounted at both ends of the conveyor belt 2, an upper plate 5 fixedly mounted on the base 1 via support columns 4, a lifting mechanism on the upper plate 5, a servo motor 6 fixedly mounted on the upper plate 5, a worm gear 7 connected to the output shaft of the servo motor 6 via a transmission mechanism, a worm wheel 8 meshing with the worm gear 7, a threaded rod 9 internally threaded onto the worm wheel 8, one end of the threaded rod 9 fixedly mounted on a limiting plate 10, and the other end fixedly mounted on a flattening cylinder 11, a pressure plate 12 and an insulating pressure plate 13 fixedly mounted on the output shaft of the flattening cylinder 11, a limiting plate 10 slidably connected to a first guide rod 14, and a core receiving mechanism at the end of the conveyor belt 2.

[0028] The working principle of the high-voltage capacitor withstand voltage test conveying mechanism proposed in this utility model is as follows: First, the capacitor core 39 is transferred from the previous station to the conveyor belt 2. Then, the capacitor core 39 is conveyed along the conveyor belt 2. After the photoelectric sensor 3 determines the positioning position, the conveyor belt 2 conveys the capacitor core 39 directly below the insulating pressure plate 12. Then, the servo motor 6 is started, and the output shaft of the servo motor 6 drives the transmission mechanism to move, thereby driving the worm gear 7 to rotate, which in turn drives the worm wheel 8 to rotate, thereby driving the threaded rod 9 to rise, which in turn drives the flattening cylinder 11 to rise. When it rises to the set height, the flattening cylinder 11 is activated, thereby driving the pressure plate 12 and the insulating pressure plate 13 to press down, using the insulating... The insulating pressure plate 13 presses the capacitor core 39 to a specified thickness. Then, through the positive and negative electrodes on both sides of the insulating pressure plate 13, an 8-12kV high voltage is input to both ends of the capacitor core 39 for a withstand voltage test. If the capacitor is broken down and short-circuited, the high voltage test electronic equipment connected to both ends of the positive and negative electrodes will alarm, and the high voltage test will fail. The flattening cylinder 11 will be raised, and the conveyor belt 2 will transport the scrapped capacitor core 39 in reverse to the front scrap box. If the high voltage test passes, the high voltage test electronic equipment connected to both ends of the positive and negative electrodes will discharge the capacitor. After ensuring that the capacitor has no voltage, the flattening cylinder 11 will be raised, and the conveyor belt 2 will be transported backward. After the photoelectric sensor 3 at the rear end detects the capacitor core 39, the core receiving mechanism will be activated to collect it.

[0029] It is worth noting that when the threaded rod 9 rises or falls, the timing belt limit plate 10 rises or falls. Since the limit plate 10 is slidably connected to the first guide rod 14, the threaded rod 9 will not rotate.

[0030] In one embodiment, the transmission mechanism includes a first synchronous pulley 15 fixedly mounted on the output shaft of the servo motor 6. The first synchronous pulley 15 is connected to a second synchronous pulley 16 via a first synchronous belt 35. The second synchronous pulley 16 is fixedly mounted on the worm gear 7. The worm gear 7 is rotatably mounted on the connector 17. The worm wheel 8 is rotatably mounted on the connector 17. The connector 17 is fixedly mounted on the upper top plate 5.

[0031] The working principle of the high voltage capacitor withstand voltage test conveying mechanism proposed in this utility model is as follows: by starting the servo motor 6, the first synchronous pulley 15 is driven to rotate, which in turn drives the second synchronous pulley 16 to rotate through the first synchronous belt 35, thereby driving the worm gear 7 to rotate.

[0032] In one embodiment, the core-connecting mechanism includes a rodless cylinder 18 fixedly mounted on the conveyor belt 2. A baffle 19 is fixedly mounted on the output shaft of the rodless cylinder 18. The baffle 19 is used to push the capacitor core 39 onto the core-connecting plate 20. The core-connecting plate 20 is fixedly mounted on the swing plate 21. The swing plate 21 is rotatably mounted on the fixed plate 22.

[0033] In one embodiment, for the swing plate 21, the lower part of the swing plate 21 is in contact with the fixed seat 23, the fixed seat 23 is fixedly connected to the output shaft of the swing cylinder 24, and the swing cylinder 24 is fixedly mounted on the frame base plate 25.

[0034] In one embodiment, the fixed plate 22 is slidably connected to a lifting core support plate 26, a slider 27 is fixed to the back of the lifting core support plate 26, a ball screw 28 is threadedly connected to the slider 27, a second guide rod 29 is slidably connected to the slider 27, the ball screw 28 is rotatably installed inside the fixed plate 22, and the second guide rod 29 is fixedly installed inside the fixed plate 22.

[0035] In one embodiment, the ball screw 28 is fixedly mounted with a third synchronous pulley 30, which is connected to a fourth synchronous pulley 32 via a second synchronous belt 31. The fourth synchronous pulley 32 is fixedly mounted with a reducer 33, and the reducer 33 is fixedly mounted with a drive motor 34.

[0036] In one embodiment, the fixing plate 22 is fixedly installed on the frame base plate 25, the frame base plate 25 is fixedly installed with an insulating base 36, and a base 1 is fixedly installed above the insulating base 36.

[0037] In one embodiment, for the photoelectric sensor 3, the photoelectric sensor 3 is fixedly installed on the sensor mounting base 37, one end of the support column 4 is fixedly installed on the base 1, the other end of the support column 4 is fixedly installed on the upper top plate 5, the first guide rod 14 is fixedly installed on the upper top plate 5, and a stop block 38 is fixedly installed on the top of the first guide rod 14.

[0038] The working principle of the high voltage capacitor withstand voltage test conveying mechanism proposed in this utility model is as follows: if the capacitor core 39 passes the high voltage test, the high voltage test electronic equipment connected to the positive and negative electrode plates will discharge the capacitor to ensure that the capacitor has no voltage. After that, the flattening cylinder 11 is lifted, the conveyor belt 2 is conveyed backward, and the photoelectric sensor 3 at the rear end detects the capacitor core 39. The rodless cylinder 18 drives the baffle 19 to push forward, pushing the capacitor core 39 onto the receiving plate 20. Then, the swing cylinder 24 is activated, thereby pushing the fixed seat 23 to move, which in turn causes the swing plate 21 to rotate, thereby conveying the capacitor core 39 onto the lifting receiving plate 26.

[0039] Furthermore, the drive motor 34 is started, which drives the reducer 33 to move, thereby driving the fourth synchronous pulley 32 to rotate. This, in turn, drives the third synchronous pulley 30 to rotate via the second synchronous belt 31, which in turn drives the ball screw 28 to rotate. This, in turn, drives the slider 27 to descend, thereby driving the lifting core support plate 26 to descend a certain distance, thus ensuring that the capacitor core 39 continues to be placed on the lifting core support plate 26.

[0040] It is worth noting that the slider 27 is limited by the second guide rod 29, so it will not rotate, thus ensuring that the lifting core support plate 26 can only rise or fall.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
