Description

Technical Field

[0001] The invention belongs to the technical field of transformers, and in particular relates to a transformer testing device and a testing method. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. Transformers need to be tested after production.

[0003] Existing detection technology usually performs a withstand voltage test by manually calibrating the electrical interface and then connecting the high-voltage power supply. This method can only test a single sample, and changing samples is cumbersome and inefficient. At the same time, it requires a high degree of caution from the test personnel and there is a risk of electric shock. The automatic clamping and calibration mechanical arm is expensive and has a low cost-effectiveness ratio, and is not suitable for small manufacturers. In response to the above technical problems, the applicant has retrieved some existing technologies, such as the Chinese patent with patent announcement number CN114778898A. When in use, the sample to be tested is first fixed from the upper surface by a pressure plate during the downward movement of the voltage output rod. As the hydraulic rod moves downward, the push plates on both sides move toward the center to fix and calibrate the sample to be tested from both sides. Finally, the voltage output rod is connected to the power interface. However, when the angle of the transformer placed on the conveyor belt is not correct, the push plate will push the transformer to move, causing the transformer to rotate, which will cause problems in the positioning of the transformer, and will cause the connection position on the transformer to be misaligned with the position of the voltage output rod, thereby causing the voltage output rod to be unable to be connected to the transformer.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0025] like Figure 1-Figure 6 As shown, a transformer testing device provided by the present invention comprises a base 1, a conveyor belt 2 is rotatably mounted on the base 1, a rotating power member 3 for driving the conveyor belt 2 to rotate is fixedly mounted on the base 1, a bracket 4 is fixedly mounted on the base 1, a lifting plate 5 is slidably mounted on the bracket 4, and a first servo module 6 for driving the lifting plate 5 to move up and down is arranged on the base 1; A support plate 7 is slidably installed in the middle of the lifting plate 5, a first positioning plate 9 is rotatably installed at one end of the support plate 7, and a first telescopic member 8 that drives the support plate 7 to move is fixedly installed on the lifting plate 5, a top plate 22 is fixedly installed on the first positioning plate 9, a cross plate 26 is provided on the top plate 22, and an adjusting component 37 for adjusting the position of the cross plate 26 is provided on the top plate 22, a second positioning plate 27 is slidably installed on the cross plate 26, a guide plate 35 is fixedly installed at one end of the second positioning plate 27, an angle is set between the guide plate 35 and the second positioning plate 27, and the end of the guide plate 35 that contacts the second positioning plate 27 is the higher end, a third elastic member 29 is fixedly installed on the cross plate 26, one end of the third elastic member 29 is connected to the second positioning plate 27, a test probe 34 is provided on the second positioning plate 27, and the test probe 34 is connected to the test equipment body 18 on the top plate 22.

[0026] In actual application of this embodiment, the horizontal distance from the test probe 34 to the first positioning plate 9 is adjusted by the adjustment component 37 according to the model of the transformer to be tested. The distance is the same as the distance from the test connection member on the transformer to the side of the transformer in contact with the first positioning plate 9. Then, the position of the test probe 34 on the second positioning plate 27 is adjusted so that the distance from the test probe 34 to the connecting line between the guide plate 35 and the second positioning plate 27 is the same as the distance from the test connection member on the transformer to the other side. The lifting plate 5 is driven downward by the first servo module 6 to move the first positioning plate 9 to a height capable of contacting the transformer. The transformer to be tested is placed on the conveyor belt 2, and the conveyor belt 2 is driven to rotate by the rotating power part 3 to transport the transformer. When the transformer moves to the position where the first positioning plate 9 is located, it will contact the first positioning plate 9. When the surface of the transformer close to the lifting plate 5 is parallel to the lifting plate 5, the conveyor belt 2 stops rotating after the transformer contacts the first positioning plate 9. When the surface of the transformer close to the lifting plate 5 is not parallel to the lifting plate 5, one side of the transformer will first contact the first positioning plate 9 and push the first positioning plate 9 to rotate. Finally, the conveyor belt 2 stops rotating after the first positioning plate 9 is completely in contact with the surface of the transformer, and the top plate 22 rotates with the first positioning plate 9. At this time, the adjustment component 37 drives the cross plate 26 to move downward. When the cross plate 26 moves downward, the guide plate 35 first contacts the side of the transformer. Since the guide plate 35 is tilted, when the cross plate 26 continues to descend, the guide plate 35 will push the second positioning plate 27 to move along the cross plate 26. When the second positioning plate 27 moves horizontally, it will compress the third elastic member 29. When the connecting line of the guide plate 35 and the cross plate 26 contacts the side of the transformer, the second positioning plate 27 contacts the top of the transformer and presses the transformer onto the conveyor belt 2 to fix the transformer. At the same time, the test probe 34 is located directly above the test connection member on the transformer. After that, the test probe 34 moves downward to connect with the transformer, and the transformer is tested through the test equipment body 18. After the test is completed, the adjusting component 37 drives the cross plate 26 to move upward so that the second positioning plate 27 leaves the transformer, and then the first telescopic member 8 drives the support plate 7 to move, so that the first positioning plate 9 leaves the transformer. At this time, the lifting plate 5 moves upward under the drive of the first servo module 6 and the tested transformer can be transported through the conveyor belt 2. Repeating the above steps can repeat the transformer test.

[0027] In an example of the present embodiment, the first servo module 6 is a motor screw mechanism, but it can also be a hydraulic cylinder or other structure that can drive the lifting plate 5 to move. The first telescopic member 8 is an electric telescopic rod, and of course it can also be a hydraulic cylinder or other component that can actively change the length. The first positioning plate 9 is driven to move by the first telescopic member 8.

[0028] like Figure 1-Figure 5 As shown, a transformer testing device provided by the present invention is provided, wherein a fixing plate 10 is fixedly mounted on the first positioning plate 9, the fixing plate 10 is a semicircular structure and its center is located on the rotation axis of the first positioning plate 9, the fixing plate 10 is slidably connected to the support plate 7 and the fixing plate 10 is made of a magnetic material, a first electromagnet 11 is fixedly mounted on the side of the support plate 7, the first electromagnet 11 is in sliding contact with the fixing plate 10, and the first electromagnet 11 adsorbs the fixing plate 10 after being energized.

[0029] Specifically, two groups of sliders 15 symmetrically distributed on both sides of the rotation axis are slidably installed on the first positioning plate 9, and the sliders 15 pass through the first positioning plate 9. A roller 17 is rotatably installed on the end of the slider 15 away from the lifting plate 5. A first elastic member 14 is fixedly installed on the end of the slider 15 close to the lifting plate 5. A pressure sensor 13 is connected to the end of the first elastic member 14 away from the slider 15. Two groups of substrates 12 are fixedly installed on the first positioning plate 9, and the pressure sensors 13 are fixedly installed on the corresponding substrates 12.

[0030] Specifically, two groups of second electromagnets 16 are fixedly mounted on the first positioning plate 9 . The second electromagnets 16 correspond to the positions of the slider 15 . The second electromagnets 16 are in sliding contact with the slider 15 , and the slider 15 is made of magnetic material. The second electromagnets 16 adsorb the slider 15 after being energized.

[0031] Specifically, two groups of telescopic rods 19 symmetrically distributed on both sides of the support plate 7 are fixedly installed on the lifting plate 5, a top block 21 is fixedly installed on the end of the telescopic rod 19 away from the lifting plate 5, and a second elastic member 20 arranged around the telescopic rod 19 is fixedly installed on the lifting plate 5. The end of the second elastic member 20 away from the lifting plate 5 is fixedly connected to the top block 21. When the second elastic member 20 is in the original length state, the top block 21 contacts the first positioning plate 9 and the first positioning plate 9 is parallel to the lifting plate 5.

[0032] In actual application of this embodiment, the transformer is transported by the conveyor belt 2. When the surface of the transformer close to the lifting plate 5 is parallel to the lifting plate 5, the surface of the transformer will first contact with the two groups of rollers 17 and simultaneously push the slider 15 to move. At this time, the first elastic member 14 is compressed to generate pressure on the pressure sensor 13. When the surface of the transformer close to the lifting plate 5 is not parallel to the lifting plate 5, one side of the transformer is in contact with the first positioning plate 9. As the transformer moves, the first positioning plate 9 is pushed to rotate. When the first positioning plate 9 rotates, first a group of rollers 17 contacts the surface of the transformer. The transformer continues to move driven by the conveyor belt 2. At this time, the transformer will push the first positioning plate 9 to continue to rotate through the rollers 17 until another group of rollers 17 contacts the surface of the transformer. After that, the two groups of rollers 17 will generate pressure on the pressure sensor 13. When the first positioning plate 9 rotates, one group of second elastic members 20 will be compressed. When the pressures detected by the two groups of pressure sensors 13 are the same, the conveyor belt 2 stops moving, and then the first telescopic member 8 drives the first positioning plate 9 to approach the transformer and further compresses the first elastic member 14. When the pressure sensor 13 detects the set pressure reading, the first telescopic member 8 stops moving. At this time, the side of the transformer is completely in contact with the surface of the first positioning plate 9, so that the test connection area on the transformer can be positioned in one direction through the first positioning plate 9. After the side of the transformer is completely in contact with the surface of the first positioning plate 9, the first electromagnet 11 is energized to adsorb the fixing plate 10, thereby fixing the first positioning plate 9 to prevent the first positioning plate 9 from rotating. At the same time, the second electromagnet 16 is energized to adsorb the slider 15 for fixing The first positioning plate 9 is fixed so that when the angle of the transformer is not adjusted after being placed on the conveyor belt 2, the first positioning plate 9 can be pushed to rotate by the roller 17, the slider 15 and the first elastic member 14 after the transformer contacts the first positioning plate 9, and the readings are detected by the pressure sensors 13 on both sides so that the transformer stops moving when the first positioning plate 9 is parallel to the surface of the transformer. The transformer can complete the adjustment of the first positioning plate 9 without directly contacting the first positioning plate 9, avoiding the impact of the transformer directly contacting the first positioning plate 9 on the first positioning plate 9, the lifting plate 5 and various components, avoiding the deformation of the first positioning plate 9 and its mounting components, ensuring that the first positioning plate 9 is in a normal state to position the transformer, and further improving the accuracy of transformer positioning; When the test is completed, the first telescopic member 8 drives the first positioning plate 9 to move away from the transformer, so that the first positioning plate 9 is separated from the transformer, and then the subsequent lifting plate 5 will not cause friction on the surface of the transformer when it moves upward. After the group of transformers is transported away by the conveyor belt 2, the first telescopic member 8 returns to its original state. At this time, the first electromagnet 11 and the second electromagnet 16 are powered off, and the slider 15 is reset under the action of the first elastic member 14, and the first positioning plate 9 is reset under the action of the second elastic member 20.

[0033] In one embodiment of the present invention, the first elastic member 14 and the second elastic member 20 are respectively the first spring and the second spring, and may of course be other elastic members such as elastic balls. The pressure sensor 13 is applied with pressure by compression of the first spring, and the first positioning plate 9 is applied with a reset thrust by compression of the second spring.

[0034] like Figure 5 , Figure 6As shown, a transformer testing device provided by the present invention is provided, two groups of connecting plates 28 are fixedly installed on the second positioning plate 27, the connecting plates 28 are slidably connected to the transverse plate 26 and one end of the third elastic member 29 is fixedly connected to one group of connecting plates 28, the third elastic member 29 is distributed along the length direction of the transverse plate 26, a third electromagnet 36 is fixedly installed on one group of connecting plates 28, the third electromagnet 36 is in sliding contact with the transverse plate 26, and the third electromagnet 36 adsorbs the transverse plate 26 after being energized, and the transverse plate 26 is made of magnetic material.

[0035] Specifically, a groove 30 is provided on the second positioning plate 27 and a movable frame 32 is slidably installed on the second positioning plate 27, a third telescopic member 33 is fixedly installed on the movable frame 32, the third telescopic member 33 passes through the groove 30 and the output end of the third telescopic member 33 is fixedly connected to the test probe 34, a threaded rod 31 is rotatably installed on the connecting plate 28, and the threaded rod 31 drives the movable frame 32 to move.

[0036] When the present embodiment is actually used, the horizontal distance from the cross plate 26 to the first positioning plate 9 is adjusted according to the type of transformer to be detected, and then the threaded rod 31 is rotated to adjust the position of the movable frame 32, and then the adjusting assembly 37 drives the cross plate 26 to move downward. When the cross plate 26 moves downward, the guide plate 35 first contacts the side of the transformer. Since the guide plate 35 is tilted, when the cross plate 26 continues to descend, the guide plate 35 will push the second positioning plate 27 to move along the cross plate 26. When the connecting line of the guide plate 35 and the cross plate 26 contacts the side of the transformer, the second positioning plate 27 contacts the top of the transformer and presses the transformer onto the conveyor belt 2 to fix the transformer. The test probe 34 is located directly above the test connection component on the transformer, and then the third telescopic member 33 drives the test probe 34 to move downward to connect with the transformer. After the second positioning plate 27 contacts the upper surface of the transformer, the third electromagnet 36 is energized to make it absorb the horizontal plate 26, thereby realizing the horizontal fixation of the second positioning plate 27. At this time, the connecting line of the guide plate 35 and the horizontal plate 26 is flush with the side of the transformer. The guide plate 35 can be used to position the test connection area on the transformer in another direction. In conjunction with the positioning of the transformer in another direction by the first positioning plate 9, the position of the test connection structure on the transformer can be accurately located, ensuring the accurate connection between the test probe 34 and the transformer, and avoiding damage to the test probe 34 or the connecting components on the transformer. When the second positioning plate 27 moves laterally, it will compress the third elastic member 29. After the test is completed, when the second positioning plate 27 is separated from the transformer, the third electromagnet 36 is powered off. At this time, the second positioning plate 27 is reset under the action of the third elastic member 29. The first positioning plate 9 and the guide plate 35 can be adaptively rotated or moved when the transformer is placed on the conveyor belt 2 at different angles, so that transformers with different placement forms can be flexibly positioned, thereby improving the flexibility and comprehensiveness of transformer positioning, and further improving the accuracy of transformer positioning.

[0037] In one example of the present invention, the third elastic member 29 is a third spring, and of course it can also be other elastic members such as an elastic ball. The third spring applies a reset force to the second positioning plate 27. The third telescopic member 33 is a third electric telescopic rod, and of course it can also be other members that can actively change the length, such as a hydraulic cylinder. The test probe 34 is driven to move by the third electric telescopic rod.

[0038] like Figure 5 As shown, a transformer testing device provided by the present invention is provided. The adjustment component 37 includes a moving plate 24, and the moving plate 24 slides on the bottom surface of the top plate 22. A second servo module 23 that drives the moving plate 24 to move is arranged on the top plate 22. The moving trajectory of the moving plate 24 is a straight line perpendicular to the first positioning plate 9. A second telescopic member 25 is fixedly installed on the bottom surface of the moving plate 24, and the output end of the second telescopic member 25 is fixedly connected to the cross plate 26.

[0039] In actual application of this embodiment, the second servo module 23 drives the movable plate 24 to move, thereby adjusting the horizontal distance from the test probe 34 to the first positioning plate 9, so as to adapt to the testing of different types of transformers, and the second telescopic member 25 drives the horizontal plate 26 to move up and down.

[0040] In one embodiment of the present invention, the second servo module 23 is a motor screw mechanism, but it can also be a hydraulic cylinder or other structure that can drive the movable plate 24 to move. The second telescopic member 25 is a second electric telescopic rod, and of course it can also be a hydraulic cylinder or other component that can actively change the length. The second electric telescopic rod drives the horizontal plate 26 to move up and down.

[0041] like Figure 1-Figure 6 As shown, a transformer testing method provided by the present invention is applied to the transformer testing device described above, and comprises the following steps: Step S1: adjusting the horizontal distance between the test probe 34 and the first positioning plate 9 through the adjustment component 37 according to the model of the transformer to be tested, and then adjusting the position of the test probe 34 on the second positioning plate 27; Step S2: The first servo module 6 drives the lifting plate 5 to move downward so that the first positioning plate 9 moves to a height that can contact the transformer, the transformer to be tested is placed on the conveyor belt 2, and the conveyor belt 2 is driven by the rotating power part 3 to rotate to transport the transformer; Step S3: After the transformer contacts the first positioning plate 9, one side of the transformer is first positioned by the first positioning plate 9, and then the other side of the transformer is positioned by the guide plate 35; Step S4: After the positioning is completed, the test probe 34 is connected to the transformer for testing. After the test is completed, the transverse plate 26 and the first positioning plate 9 are separated from the transformer, and the transformer is continued to be transported by the conveyor belt 2.
