Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a capacitor withstand voltage testing device. Background Technology

[0002] Capacitance (or capacitance) is a physical quantity that describes a capacitor's ability to store electrical charge. From a physics perspective, a capacitor is a static charge storage medium, meaning that the charge can persist for a long time; this is its characteristic. Capacitors have a wide range of applications and are indispensable electronic components in the electronics and power industries. They are mainly used in circuits for power supply filtering, signal filtering, signal coupling, resonance, compensation, charging and discharging, energy storage, and DC blocking.

[0003] Patent CN119456431B discloses a capacitor testing device and method, including a bottom disc with a rotating frustum rotatably connected to its outer end. Five first slots are arranged around the top of the rotating frustum. A drive motor has a drive plate fixedly connected to its main shaft, with the top of the drive plate fixedly connected to the rotating frustum. A top drive structure is fixedly connected to the bottom disc. A bottom drive structure is also on the bottom disc. Each of the first slots has a capacitor detection and feeding module fixedly connected to it, and the capacitor detection and feeding module is connected to the top drive structure. Each capacitor detection and feeding module has a corresponding drive assembly fixedly connected to the upper inner bottom of the rotating frustum. Each drive assembly is located directly below the corresponding capacitor detection and feeding module and is connected to the bottom drive structure. This invention removes unqualified capacitors and performs cyclic testing.

[0004] There are still some problems with capacitors during withstand voltage testing.

[0005] As a core component of electronic and power equipment, the withstand voltage performance of capacitors directly determines the safety and reliability of products. Withstand voltage testing is a mandatory inspection process before leaving the factory.

In addition, conventional fixtures have poor adaptability and are difficult to be compatible with capacitors of different specifications. The terminals and test probes are prone to poor contact, which can lead to test errors, flashover, or breakdown risks. This cannot meet the needs of batch, efficient, and stable automated testing.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The present invention has a reasonable structure. When the movable plate needs to be moved, the servo motor operates to rotate the threaded rod. A horizontal plate is threadedly connected to the threaded rod. The rotation of the threaded rod causes the horizontal plate to move. The movement of the horizontal plate drives the frame to move, which facilitates the sliding of the sleeve on the limit rod, increasing the stability of the frame movement. The movement of the frame causes the side plate to press against the pulley, which facilitates the sliding of the slider on the movable plate on the slide rail, allowing the movable plate to move horizontally.

[0019] 2. In this invention, a bracket is fixedly connected to the top of the movable plate. The bracket moves by moving the movable plate. Insert rods are inserted at both ends of the bracket, and a clamping plate is fixedly connected to one end of each insert rod. The clamping plate moves by moving the bracket, thereby facilitating the rubber pad on the inner wall of the clamping plate to adhere to the surface of the capacitor for fixation by the elastic force of the second spring.

[0020] 3. In this invention, after the capacitor is fixed, the cylinder on the limiting plate pushes the connector. Hinges are fixedly connected to both sides of the connector. The movement of the connector drives the hinges to move. A first linkage plate is rotatably connected to the hinges. The other end of the first linkage plate is rotatably connected to one end of a second linkage plate. The other end of the second linkage plate is fixedly connected to the rotating rod. The movement of the hinges drives the rotating rod to rotate through the second linkage plate on the first linkage plate, thereby facilitating the rotation of the arm plate on the connector, so that the elastic clip can be connected to the terminals of the capacitor for withstand voltage testing.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example: Reference Figure 1 - Figure 7 The capacitor withstand voltage testing device shown includes a workbench 1, a base plate 101 fixedly connected to the bottom surface of the workbench 1, a control panel 102 mounted on the surface of the workbench 1, a support plate 103 fixedly mounted on one side of the top surface of the workbench 1, a testing machine 104 fixedly mounted on the other side of the top surface of the workbench 1, and an operating table 105 fixedly mounted on the surface of the testing machine 104. It also includes a sliding component, a positioning component, and a testing component. The sliding component is mounted on the support plate 103 for horizontally moving the position of the movable plate 209, the positioning component is mounted on the movable plate 209 for fixing the capacitor, and the testing component is mounted on the testing machine 104 for testing the capacitor.

[0032] Specifically, it should be noted that the servo motor 2 is electrically connected to the control panel 102 via wires, and the spring clip 404 is connected to the terminals on the capacitor to facilitate the withstand voltage test of the capacitor. The specific voltage test is based on existing technology and will not be elaborated on here.

[0033] In one embodiment of this invention, the sliding assembly includes a servo motor 2 fixedly mounted on the worktable 1. A threaded rod 201 is fixedly connected to the output end of the servo motor 2. A horizontal plate 202 is threadedly connected to the threaded rod 201. The top end of the threaded rod 201 is rotatably connected to the bottom surface of the support plate 103. Both ends of the horizontal plate 202 are fixedly connected to the middle of the inner wall of the frame 203. A pair of limiting rods 204 are fixedly connected to the worktable 1. A sleeve 205 is slidably connected to the pair of limiting rods 204. One end of the sleeve 205 is fixedly connected to the middle of the surface of the frame 203. Side plates 205 are fixedly connected to the middle of both sides of the frame 203. 6. A pulley 207 is attached to the top surface of the side plate 206. The pulley 207 is rotatably connected to the bearing seat 208. One end of the bearing seat 208 is fixedly connected to the bottom of one end of the movable plate 209. A slider 210 is fixedly connected to the middle of the bottom surface of the movable plate 209. The slider 210 is slidably connected to the slide rail 211. The slide rail 211 is fixedly installed at the middle of the top surface of the support plate 103. A pair of fixing posts 212 are fixedly connected to the slide rail 211. A first spring 213 is fixedly connected to the pair of fixing posts 212. The other end of the first spring 213 is fixedly connected to the docking post 214. The docking post 214 is fixedly installed on the side of the movable plate 209.

[0034] Specifically, when the movable plate 209 needs to be moved, the servo motor 2 operates to rotate the threaded rod 201. The threaded rod 201 is threadedly connected to the horizontal plate 202. The rotation of the threaded rod 201 causes the horizontal plate 202 to move. The movement of the horizontal plate 202 drives the frame 203 to move, thereby facilitating the sliding of the sleeve 205 on the limiting rod 204 and increasing the stability of the frame 203's movement. The top of the side plate 206 is set at an angle, and the top angle of the side plate 206 is attached to the pulley 207. The movement of the frame 203 causes the side plate 206 to press against the pulley 207, thereby facilitating the sliding of the slider 210 on the movable plate 209 on the slide rail 211, allowing the movable plate 209 to move horizontally.

[0035] As one embodiment of this invention, the positioning component includes a bracket 3 fixedly installed on the top surface of the movable plate 209. Insert rods 301 are movably inserted at both ends of the bracket 3. A collar 302 is sleeved on one end of the insert rod 301. A second spring 303 is sleeved on the insert rod 301. The two ends of the second spring 303 are fixedly connected to one side of the bracket 3 and one side of the collar 302, respectively. A clamping plate 304 is fixedly connected to the other end of the insert rod 301. A rubber pad 305 is fixedly connected to the inner wall of the clamping plate 304.

[0036] Specifically, a bracket 3 is fixedly connected to the top of the movable plate 209. The bracket 3 moves by moving the movable plate 209. Insert rods 301 are inserted at both ends of the bracket 3, and a clamping plate 304 is fixedly connected to one end of the insert rod 301. The clamping plate 304 moves by moving the bracket 3, so that the rubber pad 305 on the inner wall of the clamping plate 304 can be fixed to the surface of the capacitor by the elastic force of the second spring 303.

[0037] As one embodiment of this invention, the testing assembly includes a limiting plate 4 fixedly installed on one side of the testing machine 104. A pair of rotating rods 401 are rotatably connected to the limiting plate 4. A docking seat 402 is fixedly connected to the top of the pair of rotating rods 401. One end of the docking seat 402 is fixedly connected to the arm plate 403. An elastic clip 404 is fixedly connected to the inner side of the other end of the arm plate 403. An electric wire 405 is fixedly connected to the elastic clip 404. The other end of the electric wire 405 is fixedly connected to the testing machine 104. A cylinder 406 is fixedly installed in the middle of the limiting plate 4. A connector 407 is fixedly connected to one end of the cylinder 406. Hinges 408 are fixedly installed on both sides of the connector 407. A first linkage plate 409 is rotatably connected to the hinges 408. A second linkage plate 410 is rotatably connected to the other end of the first linkage plate 409. The other end of the second linkage plate 410 is fixedly connected to the rotating rod 401.

[0038] Specifically, after the capacitor is fixed, the cylinder 406 on the limiting plate 4 pushes the connector 407. Hinges 408 are fixedly connected to both sides of the connector 407. The movement of the connector 407 drives the hinges 408 to move. A first linkage plate 409 is rotatably connected to the hinges 408. The other end of the first linkage plate 409 is rotatably connected to one end of the second linkage plate 410. The other end of the second linkage plate 410 is fixedly connected to the rotating rod 401. The movement of the hinges 408 drives the rotating rod 401 to rotate through the second linkage plate 410 on the first linkage plate 409, thereby facilitating the rotation of the arm plate 403 on the docking seat 402, so that the spring clip 404 can dock with the capacitor terminals to perform a withstand voltage test.

[0039] The working principle of this invention is as follows: When the movable plate 209 needs to be moved, the servo motor 2 operates to rotate the threaded rod 201. The threaded rod 201 is threadedly connected to the horizontal plate 202. The rotation of the threaded rod 201 causes the horizontal plate 202 to move. The movement of the horizontal plate 202 drives the frame 203 to move, thereby facilitating the sliding of the sleeve 205 on the limiting rod 204 and increasing the stability of the frame 203's movement. The movement of the frame 203 causes the side plate 206 to press against the pulley 207, thereby facilitating the sliding of the slider 210 on the movable plate 209 on the slide rail 211, allowing the movable plate 209 to move horizontally.

[0040] A bracket 3 is fixedly connected to the top of the movable plate 209. The bracket 3 moves by moving the movable plate 209. Insert rods 301 are inserted at both ends of the bracket 3, and a clamping plate 304 is fixedly connected to one end of the insert rod 301. The clamping plate 304 moves by moving the bracket 3, so that the rubber pad 305 on the inner wall of the clamping plate 304 can be fixed to the surface of the capacitor by the elastic force of the second spring 303.

[0041] After the capacitor is fixed, the cylinder 406 on the limiting plate 4 pushes the connector 407. Hinges 408 are fixedly connected to both sides of the connector 407. The movement of the connector 407 drives the hinges 408 to move. A first linkage plate 409 is rotatably connected to the hinges 408. The other end of the first linkage plate 409 is rotatably connected to one end of the second linkage plate 410. The other end of the second linkage plate 410 is fixedly connected to the rotating rod 401. The movement of the hinges 408 drives the rotating rod 401 to rotate through the second linkage plate 410 on the first linkage plate 409, thereby facilitating the rotation of the arm plate 403 on the docking seat 402, so that the spring clip 404 can dock with the capacitor terminals to perform the withstand voltage test.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
