Description

Technical Field

[0001] The present invention relates to the technical field of relay detection, and in particular to a nanocrystalline relay withstand voltage testing device. Background Art

[0002] A relay is a commonly used electronic control device. Essentially, it's an "automatic switch" that uses a smaller current to control a larger current, preventing users from directly manipulating large currents and risking electric shock. It can provide automatic regulation, safety protection, or circuit switching, and is therefore widely used in various machines and equipment. The weight of a relay primarily depends on the efficiency of the magnetic material—that is, the electromagnetic force it provides per unit weight. At the same weight, a higher electromagnetic force significantly improves vibration resistance, surge current resistance, and response speed. Therefore, using high-permeability materials to achieve greater flux transfer with a smaller cross-section is the most effective approach to high-performance, high-reliability, and lightweight design. Nanocrystalline materials have extremely low hysteresis and eddy current losses, maintaining high permeability in the kHz to MHz high-frequency range, making them suitable for high-frequency switching scenarios. With the rapid development of 5G, new energy, and other fields, nanocrystalline relays will become key components in high-precision power electronics systems. Nanocrystalline relays typically require a withstand voltage test during production. This test verifies whether the relay's insulation structure can withstand the internal voltage of the power system without breakdown or discharge. Existing testing methods rely on manual testing using a withstand voltage tester. This method has a low degree of automation, low detection efficiency, and requires a large amount of manpower, often leading to missed detections. For example, the description of a "fully automatic relay testing machine" disclosed in a Chinese invention patent (publication number: CN115236466B) states that existing testing steps are still performed manually, resulting in a low degree of automation, low detection efficiency, and the need for a large amount of manpower. This often results in missed detections. While some semi-automatic testing equipment is currently available on the market, it is still limited to simple distributed testing and struggles to achieve highly integrated continuous automatic testing, resulting in low efficiency and an inability to meet production needs. The above patents can prove the defects of the existing technology, so the present invention proposes a nanocrystalline relay withstand voltage testing device. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the above-mentioned background technology and provide a nanocrystalline relay withstand voltage test device.

[0004] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: Nanocrystalline relay withstand voltage test device, including: A transmission frame, with gear shafts rotatably provided at both ends thereof, a toothed belt is wound around the two gear shafts, and an end portion of one of the gear shafts is connected to a first motor provided on the transmission frame; The testing mechanism includes a mounting frame fixed to the transmission frame, a withstand voltage tester provided on the mounting frame, an electric push rod provided on the mounting frame, a connecting plate fixed to the piston end of the electric push rod, a sleeve fixed to the connecting plate, a probe rod slidingly passing through the sleeve, a wire connected between the probe rod and the withstand voltage tester, and a first spring connected between the probe rod and the inner wall of the sleeve; The quick-disconnection vibration damping mechanism is arranged on the sleeve. When the sleeve rises and moves away from the relay, the quick-disconnection vibration damping mechanism drives the probe rod to move away synchronously and eliminate vibration.

[0007] Furthermore, a casing is fixedly provided on the transmission frame, and a plurality of arc-extinguishing plates are arranged in an array on opposite sides of the inner wall of the casing, and avoidance grooves are opened through the arc-extinguishing plates.

[0008] Furthermore, a hemispherical contact block is provided at one end of the probe away from the wire.

[0014] The beneficial effects of the present invention are as follows: In the present invention, the relay performs assembly-line transmission detection through a toothed belt. The probe rod, the first spring and the sleeve form an elastically retractable probe structure, and the probe structure is raised and lowered by an electric push rod, which can ensure that the probe rod effectively contacts the relay for detection and avoids the probe rod from breaking. At the same time, through the protection of the quick-separation damping mechanism, it is ensured that after the detection is completed, the probe rod can quickly rise and separate, avoiding vibration caused by elastic expansion and contraction, and avoiding arc generation, so as to ensure the smooth progress of continuous detection.

[0015] In the present invention, the quick separation blocking mechanism does not affect the normal elastic extension and contraction of the probe rod to resist the relay, and does not affect the normal test of the relay.

At the same time, it can effectively block the vibration and reduce the generation of arc, so as to protect the relay.

[0016] In the present invention, the relay is supported and transported by a positioning block, which can be slightly moved along the toothed belt transmission direction.

DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] like Figures 1-10 As shown, a nanocrystalline relay withstand voltage test device proposed in one embodiment of the present invention includes: The transmission frame 1 has gear shafts 2 rotatably provided at both ends, and toothed belts 3 are driven and wound around the two gear shafts 2. The end of one of the gear shafts 2 is connected to a first motor 4 provided on the transmission frame 1. When performing a withstand voltage test on the relay, the relay is placed on the toothed belt 3 (a robot can be used for clamping and loading). The first motor 4 works, and its output shaft drives the gear shaft 2 to rotate, thereby driving the toothed belt 3 to transmit, thereby transmitting the relay and realizing assembly line testing. This is a distinguishing feature of the prior art of the present invention; The distinguishing technical features of the present invention also include a testing mechanism 5, including a mounting frame 501 fixed on the transmission frame 1, a pressure tester 502 is provided on the mounting frame 501, an electric push rod 503 is provided on the mounting frame 501, a connecting plate 504 is fixed on the piston end of the electric push rod 503, a sleeve 505 is fixed on the connecting plate 504, a probe rod 506 is slidably passed through the sleeve 505, a wire 507 is connected between the probe rod 506 and the pressure tester 502, a first spring 508 is connected between the probe rod 506 and the inner wall of the sleeve 505, when the toothed belt 3 transmits the relay to the bottom of the mounting frame 501 , the toothed belt 3 stops transmitting, the electric push rod 503 works, and its piston end drives the connecting plate 504 to descend. As the connecting plate 504 descends, the probe rod 506 contacts the relay. During the contact process, the connecting plate 504 continues to move down a certain distance. At this time, the probe rod 506 moves up in the sleeve 505 and squeezes the first spring 508. It should be noted that a rubber block is constructed on the probe rod 506, the sleeve 505 is made of rubber material, and the first spring 508 is made of plastic material, which has normal compression and elastic deformation capabilities and can also be insulated. The probe rod 506, the first spring 508 and the sleeve 505 consist of An elastically retractable probe structure can ensure that the probe rod 506 effectively contacts the relay for testing, and can also prevent the probe rod 506 from breaking due to hard collision with the relay. In actual use, the number of probe rods 506 is two, which is a traditional dual-probe withstand voltage tester with multiple testing modes. First, independent high-voltage mode: both probes output high voltage, which are applied to two independent insulating parts of the relay, such as between the coil and the contact, and between the contact and the shell of the relay, to test multiple groups of insulation performance at the same time; second, high-voltage-loop mode: one probe outputs high voltage, and the other probe is grounded (or used as a current return line). 3. Differential test mode: The two probes apply different potentials to test the insulation strength between two points (for example, the withstand voltage between two sets of contacts of a relay). This belongs to the existing structure. When the relay test is completed, the electric push rod 503 works, and its piston end drives the connecting plate 504 to rise, thereby making the probe rod 506 move away from the relay. When the probe rod 506 moves away, the toothed belt 3 is transported again to transport the relay that has been tested away, and the subsequent relays are transported again to the bottom of the mounting bracket 501, thereby performing continuous testing, thereby improving detection efficiency. The quick-break damping mechanism 6 is arranged on the sleeve 505. When the sleeve 505 rises and moves away from the relay, the quick-break damping mechanism 6 drives the probe rod 506 to move away synchronously and eliminate vibration. Since the probe rod 506, the first spring 508 and the sleeve 505 form an elastically retractable probe structure, it can ensure that the probe rod 506 effectively contacts the relay for testing, and can also avoid the probe rod 506 from colliding with the relay and causing breakage. However, when the connecting plate 504 rises, affected by the elastic force of the first spring 508, the sleeve 505 rises first, and then the probe rod 506 rises. The two rise in succession, and when the probe rod 506 rises, affected by the elastic force of the first spring 508, the probe rod 506 will produce a reciprocating amplitude motion, which is not suitable for the test. It is easy to cause the arc to reignite twice or multiple times. By setting the quick separation damping mechanism 6, when the sleeve 505 rises, the probe rod 506 can move upward synchronously with the sleeve 505, which is not only used to speed up the separation speed of the probe rod 506 and the relay, but also can prevent the probe rod 506 from vibrating (used to prevent the probe rod 506 from initially separating from the relay at a close distance. When the probe rod 506 is away from the relay for a certain distance, even if the probe rod 506 vibrates, no arc will be generated). The quick separation damping mechanism 6 does not affect the normal elastic expansion and contraction of the probe rod 506 to resist the relay, and does not affect the normal test of the relay. However, after the test is completed, it can effectively dampen the vibration during the separation process, reduce the generation of arc, and thus play a role in protecting the relay. In this solution, the relay is tested in a pipeline transmission manner through the toothed belt 3. The probe rod 506, the first spring 508 and the sleeve 505 form an elastically retractable probe structure, and the probe structure is raised and lowered by the electric push rod 503, which can ensure that the probe rod 506 effectively contacts the relay for detection and avoids the probe rod 506 from breaking. At the same time, through the protection of the quick separation damping mechanism 6, it is ensured that after the detection is completed, the probe rod 506 can quickly rise and separate, avoiding vibration caused by elastic expansion and contraction, and avoiding arc generation, so as to ensure the smooth progress of continuous detection.

[0020] like Figure 9 and Figure 10As shown, the specific structure of the quick-disconnection anti-fibrillation mechanism 6 of the present invention is disclosed. The quick-disconnection anti-fibrillation mechanism 6 includes a bracket 601 fixed on the sleeve 505, a through slot 602 is opened on the sleeve 505, a connecting rod 603 is fixed on the probe rod 506, and the end thereof slides through the through slot 602. A plurality of conical card slots 604 are arranged in an array on the connecting rod 603, a card rod 605 is slid through the bracket 601, and a conical card block 606 is provided at the end of the card rod 605 to engage with the conical card slot 604. A second spring 607 is installed between the conical card block 606 and the bracket 601, and a release member 608 is provided on the mounting frame 501. When the probe rod 506 is separated from the relay, the release member 608 delays the release of the conical card block 60 6 cooperates with the card arrangement of the conical card slot 604. In the initial state, the conical card block 606 cooperates with one of the conical card slots 604 through the elastic force of the second spring 607. When the electric push rod 503 drives the connecting plate 504 to move downward, the probe rod 506 contacts the relay and the probe rod 506 moves upward. At this time, the conical card block 606 cooperates with the conical surface of the conical card slot 604 to force the conical card block 606 to disengage from the conical card slot 604. The probe rod 506 moves upward normally and drives the connecting rod 603 to move upward. As the probe rod 506 continues to move, the conical card block 606 slides along the surface of the connecting rod 603. When the probe rod 506 stops moving and the conical card block 606 is aligned with the other conical card slot 604, the second spring Under the elastic force of 607, the conical block 606 is again clamped in the corresponding conical groove 604, thereby temporarily fixing the probe rod 506, that is, when the probe rod 506 moves up normally, the conical block 606 and the conical groove 604 will not cause a clamping restriction on the normal upward movement of the connecting rod 603 and the probe rod 506. As the first spring 508 is compressed, the clamping cooperation of the conical groove 604 and the conical block 606 will quickly restrict the probe rod 506, so that the first spring 508 will not elastically rebound during the compression process, which can elastically buffer the resistance force between the probe rod 506 and the relay and avoid vibration caused by elastic rebound. When the test is completed, the connecting plate 504 rises, which can drive the probe rod 506 to rise synchronously, and can quickly Separation, since the release member 608 is to delay the release of the card fit of the conical block 606 and the conical slot 604, when the probe rod 506 is separated from the relay, the first spring 508 is still in a fixed state, so that the probe rod 506 has no kinetic energy, and the probe rod 506 will only move upward synchronously with the connecting plate 504, and will not vibrate downward. When the separation is a certain distance, the release member 608 will release the card fit of the conical block 606 and the conical slot 604, and then the first spring 508 releases the elastic pressure, causing the probe rod 506 to move downward (i.e., return to the initial state), so as to facilitate the normal inspection of the subsequent relay. Since the probe rod 506 is a certain distance away from the relay and vibrates due to the release of the pressure of the first spring 508, at this time,The vibration generated at this distance will not produce arc, thus ensuring the protection of the relay.

[0021] like Figure 9 and Figure 10 As shown in FIG. 1 , the specific structure of the release member 608 of the present invention is disclosed. The release member 608 includes a vertical plate 6081 fixed to the mounting frame 501. A through slot 6082 is formed through the bottom end of the vertical plate 6081. An arc-shaped protrusion 6083 is provided on one side of the vertical plate 6081. The free end of the clamping rod 605 slides through the through slot 6082 and is rotatably connected to the support rod 6084. Figure 4 Combine Figure 9 and Figure 10 As shown, the probe rod 506 is in a state away from the relay. At this time, the support rod 6084 is located below the arc-shaped protrusion 6083. When the connecting plate 504 moves down normally, the probe rod 506 can be fixed in real time by using the cooperation between the conical block 606 and the conical slot 604. When the test is completed, when the connecting plate 504 rises, the probe rod 506 will follow it to rise a certain distance. When the probe rod 506 rises, the clamping rod 605 moves upward along the through slot 6082. When the clamping rod 605 After moving upwards for a certain distance, the support rod 6084 will contact the arc-shaped protrusion 6083. As the support rod 6084 contacts the arc-shaped protrusion 6083, the clamping rod 605 is forced to move horizontally to the left, thereby releasing the cooperation between the conical clamping block 606 and the conical clamping groove 604. At this time, the probe rod 506 will move downward to reset. When the probe rod 506 moves downward to reset, it is away from the relay. Even if it vibrates up and down due to the elastic force of the first spring 508, no arc will be generated due to the vibration.

[0022] like Figure 6 and Figure 8 As shown, a further technical solution for arc extinguishing protection of the present invention is disclosed. A sleeve 7 is fixedly provided on the transmission frame 1. A plurality of arc extinguishing plates 8 are arranged in an array on opposite sides of the inner wall of the sleeve 7. An avoidance groove 9 is opened through the arc extinguishing plates 8. Although the probe rod 506 moves upward synchronously with the connecting plate 504, a slight arc will still be generated when the probe rod 506 is separated from the relay. By setting the sleeve 7, preferably, the top of the sleeve 7 has a through-hole, which does not affect the normal movement of the probe rod 506. The height of the arc extinguishing plate 8 is higher than the height of the relay, which does not affect the normal transmission of the relay. The probe rod 506 is located in the avoidance groove 9 between the arc extinguishing plates 8 on both sides. When the probe rod 506 is separated from the relay, even if an arc is generated, the arc will be pulled between the plurality of arc extinguishing plates 8, thereby breaking into a plurality of short arcs and quickly extinguishing the short arcs to achieve the effect of rapid arc extinguishing. By quickly extinguishing the arc, the relay is protected.

[0023] like Figure 4 and Figure 10As shown, a further technical solution of the present invention for the probe rod 506 is disclosed. A contact block 509 with a hemispherical structure is provided at one end of the probe rod 506 away from the wire 507. Preferably, the contact block 509 uses conductive hydrogel, which has good conductive properties and can be deformed. When the probe rod 506 contacts the relay, the contact block 509 is compressed and deformed, increasing the contact area. The larger contact area reduces the current density when the current passes through, thereby reducing the contact resistance. At the same time, the hemispherical curved surface structure has a more uniform stress distribution when under pressure, avoiding local stress concentration. The uniform contact pressure and high contact area can reduce instantaneous discharge caused by poor contact, thereby improving the detection effect.

[0024] like Figure 7 and Figure 8 As shown, a further technical solution for relay transmission positioning of the present invention is disclosed. A plurality of mounting blocks 10 are fixedly provided along the transmission surface array of the toothed belt 3. A positioning plate 11 is provided on the mounting block 10. A positioning groove 12 is provided on the top of the positioning plate 11. When the relay is transmitted and loaded, the relay can be placed in the positioning groove 12. In actual use, the positioning groove 12 is adapted to the relay. The positioning plate 11 is made of hard rubber. The relay is supported by the positioning plate 11 and the positioning groove 12 limits the relay to avoid inertial slip of the relay due to the stress generated by the start and stop of the toothed belt 3 during transmission, so as to ensure that the probe rod 506 is in effective contact with the contacts or contacts on the relay to ensure accurate voltage withstand test.

[0025] like Figure 7As shown, a further technical solution for relay transmission positioning of the present invention is disclosed. A slide groove 13 is provided on the mounting block 10. A slider 14 is constructed at the bottom of the positioning plate 11 and the slider 14 is slidably inserted in the slide groove 13. Preferably, the longitudinal sections of the slide groove 13 and the slider 14 are both constructed in a T-shape. The slider 14 can slide along the slide groove 13 at a micro distance, but cannot be separated from the slide groove 13. The two opposite sides of the slider 14 are constructed with V-shaped blocks 15. The opposite sides of the inner wall of the transmission frame 1 are slidably inserted with movable plates 16. Each movable plate 16 is constructed with a support block 17, and a V-shaped groove 19 is provided on the support block 17 to be plugged into the V-shaped block 15. A driving part 20 is provided on the transmission frame 1 for driving the two movable plates 16 to slide in opposite directions synchronously. Since the toothed belt 3 is driven by the first motor 4 and the slider 14 slides with the slide groove 13, when the positioning plate 11 is transmitted to the bottom of the connecting plate 504, the toothed belt 3 stops transmitting and drives the two movable plates 16 to slide in opposite directions synchronously through the driving part 20. When the two movable plates When 16 slides synchronously close, the V-shaped slots 19 on the two support blocks 17 are respectively plugged into the two V-shaped blocks 15. Through the V-shaped surface contact between the V-shaped blocks 15 and the V-shaped slots 19, the positioning plate 11 can be quickly fine-tuned in the transmission direction to ensure that the positioning plate 11 and the connecting plate 504 are effectively aligned, so that the probe rod 506 and the contacts on the relay are accurately aligned, thereby further improving the withstand voltage test effect. The dynamic alignment mechanism of the V-shaped slots 19 and the V-shaped blocks 15 ensures that the probe rod 506 and the relay are aligned. The position deviation of the contacts is <0.1mm, which avoids misjudgment caused by poor contact. In order to make the solution more reasonable, preferably, the top of the support block 17 is in contact with the bottom of the positioning plate 11. When the V-shaped block 15 is engaged with the V-shaped slot 19, the support block 17 can also support the positioning plate 11. When the probe rod 506 contacts the relay, it will apply a certain pressure to the relay. The support of the positioning plate 11 by the support block 17 can effectively support the relay to ensure smooth detection.

[0026] like Figure 7 As shown, the specific structure of the driving part 20 of the present invention is disclosed. The driving part 20 includes a second motor 2001 arranged on the transmission frame 1, and the output shaft of the second motor 2001 is fixedly provided with a gear 2002. Racks 2003 are fixedly provided on the two movable plates 16, and the two racks 2003 are engaged with the teeth of the gear 2002. Preferably, a fixed plate is provided on the opposite side of the inner wall of the transmission frame 1, and the second motor 2001 is provided on the fixed plate. The second motor 2001 is located between the upper and lower transmission sections of the toothed belt 3 and does not affect the normal transmission of the toothed belt 3. The second motor 2001 does work, and its output shaft drives the gear 2002 to rotate. Since racks 2003 are fixedly provided on the two movable plates 16 and the two racks 2003 are engaged with the teeth of the gear 2002, the two movable plates 16 are driven to slide synchronously in opposite directions.

[0027] like Figure 1 and Figure 3 As shown, a further technical solution for relay sorting of the present invention is disclosed. A robotic arm 21 is provided on one side of the transmission frame 1, and a collection frame 22 is provided on the side of the transmission frame 1 away from the robotic arm 21. When the relay test is completed, it follows the toothed belt 3 to be transmitted to the rightmost end, and the relay will automatically fall off. In actual use, a collection frame can be placed at the right end of the transmission frame 1 to collect the relays that have completed the inspection. When the relays are batch inspected, some defective products will exist. When defective products are detected, the robotic arm 21 works, and the mechanical gripper at its end can clamp the defective products and place them in the collection frame 22, so as to eliminate the defective products and avoid mixing defective products with good products, thereby improving practicality.

[0028] like Figure 2 and Figure 6 As shown, a further technical solution for cleaning and dust removal of the relay is disclosed. A brush plate 18 is provided on one side of the housing 7, and bristles are constructed on the brush plate 18. When the relay undergoes a withstand voltage test, it will first pass through the brush plate 18 before being transmitted to the housing 7 for testing. The bristles on the brush plate 18 will scrape the surface of the relay, which can clean and remove dust from the relay, avoid dust adhering to the contacts or the surface of the relay, and avoid dust affecting the normal contact between the probe rod 506 and the relay, thereby ensuring the result of the withstand voltage test. In order to make the solution more reasonable, preferably, the bristles are synthetic fiber bristles (such as carbon fiber, anti-static nylon), which have their own anti-static properties, are durable and easy to clean. In actual use, an exhaust mechanism can also be provided. The exhaust mechanism is located outside the housing 7, and the exhaust is combined with the scraping brush of the brush plate 18 to perform cleaning and dust removal.

[0029] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
