Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a transformer testing device. 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, the secondary coil, and the iron core. In electrical equipment and wireless circuits, it is often used to increase or decrease voltage, match impedance, and provide safety isolation. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential can be induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux intersecting the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. At present, the pins of the transformer are not cleaned during transformer testing. When the transformer is electrically tested through the pins, dust or dirt on the pins will affect the test results of the transformer, thereby reducing the accuracy of the test.

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

[0016] 1. The transformer is fixed on the mobile mechanism by means of a clamp, which avoids accidental displacement during movement and ensures the stability of the transformer. The cleaning mechanism can clean and wipe the pins of the transformer, effectively removing dust and other dirt on the pins, ensuring the cleanliness of the pins, and helping to improve the conductive effect of the transformer during electrical testing. The two electrical testing mechanisms are fixed around the transformer by means of a linkage motor and a clamping and stabilizing component, which effectively suppresses the effects of vibration and shaking and ensures the accuracy of the electrical testing process. The operator can observe the electrical test results of the transformer through external equipment, including parameters such as input current, output current, input voltage and output voltage, so as to determine whether the transformer is qualified, thereby improving convenience.

[0017] 2. By fixing the transformer on the driving connection block and utilizing the cooperation of the strip groove and the strip protrusion, the transformer can be firmly positioned on the transformer installation groove, ensuring that the transformer will not be displaced or detached during the test process, thereby improving the stability of the installation. By driving the cooperation of the threaded rod and the movable support block, the transformer can be moved. When the threaded rod is driven to rotate, the movable support block moves in the direction of the second driving plate, thereby driving the transformer to move together. Through the coordinated action of the reset tension spring, the telescopic square block and the flexible airbag, the gap between the strip protrusion of the transformer and the strip groove is reduced under the action of the downward extrusion force. The downward extrusion force can prevent the transformer from falling out upward, further improving the stability of the installation. The temperature detection component is driven by the limiting connection plate to be held against the side wall of the transformer, so that the temperature change of the transformer can be monitored in real time. By monitoring the temperature change of the transformer during the electrical test, it can be judged whether the transformer meets the production requirements, and the abnormal situation of the transformer can be discovered in advance, ensuring the safety and quality of the production process.

[0018] 3. By moving the trigger arc block and the cleaning lifting plate, the cleaning connection block and the cleaning flexible cloth can be moved up and down, so as to effectively clean the pins of the transformer. Since the bottoms of the two cleaning flexible cloths are slightly tilted, when wiping the pins of the transformer, the gap between the two cleaning flexible cloths is tighter, which can more effectively wipe the pins of the transformer, improve the cleaning effect, and prevent excessive detergent from entering the transformer to cause a short circuit, thereby ensuring that the pins of the transformer are fully cleaned to ensure the accuracy of the test results.

[0019] 4. By triggering the arc block to press against the high point of the wave surface to the low point and move the cleaning lifting plate upward, the friction between the strip protrusion and the flexible airbag can be increased, and the possibility of lifting the transformer upward when the cleaning lifting plate moves upward to drive the two cleaning flexible cloths to wipe the pins of the transformer is prevented, thereby improving the stability of the cleaning process. By triggering the arc block to press against the low point of the wave surface to the high point, the cleaning lifting plate moves downward by its own gravity, causing the flexible airbag to shrink slightly, reducing the friction between the strip protrusion and the flexible airbag. The downward wiping of the cleaning flexible cloth can drive the transformer to be pressed into the transformer mounting groove, thereby improving the contact tightness between the transformer and the bottom of the transformer mounting groove, and preventing the transformer from shaking or inaccurate testing during testing.

[0020] 5. Clean the dust and dirt on the transformer pins to avoid the influence of these substances on the test results and ensure the accuracy of the test. Clamp the two side walls of the transformer by moving the clamping stabilizing component and compressing the clamping spring to avoid changes in its position due to vibration and other reasons, thereby ensuring the accuracy of the test results. Accurately insert the transformer pins into the conductive grooves and electrically connect them to the electrical test pieces to test the electrical performance of the transformer. Use the pin avoidance grooves to avoid the clamping support blocks from abutting or squeezing the transformer pins. Use the temperature detection piece to test the temperature changes during the transformer test, so as to promptly detect excessive temperatures and avoid equipment damage and safety risks caused by them.

[0045] In one embodiment, when in use, the operator can install the transformer 100 on the moving mechanism 30, clamp the transformer 100 on the moving mechanism 30, so that the transformer 100 cannot move, and then start the driving mechanism 20. The driving mechanism 20 can drive the transformer 100 to move to the other end of the work base 10 through the moving mechanism 30. When the transformer 100 passes through the cleaning mechanism 40, the cleaning mechanism 40 can clean and wipe the pins of the transformer 100, thereby wiping off the dust and other dirt on the pins of the transformer 100 to prevent the conductive effect from being affected in the subsequent electrical testing process, thereby affecting the final test results, and improving the accuracy of the test. When the transformer 100 moves to the position of the electrical testing mechanism 50, it stops moving, and then starts the linkage motor 16. The linkage motor 16 drives the two electrical testing mechanisms 50 to approach each other, and fixes the transformer 100 through two clamping and stabilizing components 57 to prevent the vibration generated during the test from affecting its electrical test results. When the transformer 100 is clamped and fixed, The electrical testing mechanism 50 performs electrical testing on the transformer 100 (testing the input current, output current, input voltage and output voltage of the transformer 100, etc.), and the operator can observe whether it is qualified through an external device. In this case, the transformer 100 is fixed on the moving mechanism 30 by a clamping method, thereby avoiding accidental displacement during the movement and ensuring the stability of the transformer 100. The cleaning mechanism 40 can clean and wipe the pins of the transformer 100, effectively removing dust and other dirt on the pins, ensuring the cleanliness of the pins, and helping to improve the conductive effect of the transformer 100 during the electrical testing process. By linking the motor 16 and the clamping and stabilizing component 57, the two electrical testing mechanisms 50 are fixed around the transformer 100, effectively suppressing the influence of vibration and shaking, and ensuring the accuracy of the electrical testing process. The operator can observe the electrical test results of the transformer 100 through an external device, including parameters such as input current, output current, input voltage and output voltage, so as to judge whether the transformer 100 is qualified, thereby improving convenience.

[0046] In one embodiment, the operator can first install the transformer 100 to be tested on the transformer installation slot 326 of the driving connection block 321, and by clamping the strip protrusion of the transformer 100 in the strip clamping slot 327, the transformer 100 can be preliminarily positioned, and then the driving motor 21 is started, and the driving motor 21 drives the driving threaded rod 24 to rotate. Since the driving threaded rod 24 is threadedly matched with the movable support block 31, and the movable support block 31 is slidably arranged on the two driving limit rods 25, when the driving threaded rod 24 rotates, it can drive the movable support block 31 to move in the direction of the second driving plate 23. When the movable support block 31 moves, it can drive the driving connection block 321 to move in the same direction, and the driving connection block 321 moves When the driving connection block 321 is moved, it can drive the transformer 100 to move together. When the driving connection block 321 moves, it can be close to the limiting connection plate 341. When the driving connection block 321 is not moved, the reset tension spring 322 is in a stretched state and has a large pulling force. However, since the two arc block abutting rods 11 are respectively abutted on the two triggering arc blocks 343, the limiting connection plate 341 cannot move in the direction of the driving connection block 321, so the reset tension spring 322 is always in a stretched state. When the driving connection block 321 is close to the limiting connection plate 341, the tension of the reset tension spring 322 can make the telescopic square block 323 gradually enter the telescopic square groove 328, and the telescopic piston rod 324 will also gradually enter the telescopic circular groove 329. When the plug rod 324 enters the telescopic circular groove 329, it will squeeze the air in the telescopic circular groove 329, so that the air in the telescopic circular groove 329 enters the flexible airbag 325 through the airbag through groove 331. The gas entering the flexible airbag 325 can expand and deform. Since the size of the airbag mounting groove 330 is basically the same as the size of the flexible airbag 325, the flexible airbag 325 will expand into several telescopic limit grooves 332 when it is deformed. Finally, the deformation of the flexible airbag 325 causes part of the flexible airbag 325 to pass through the telescopic limit groove 332 and extend into the strip card groove 327. The inclination direction of the telescopic limit groove 332 is inclined downward, so the flexible airbag 325 that passes through the telescopic limit groove 332 and produces a partial deformation is also inclined downward. The strip protrusion of the transformer 100 is squeezed, so that the gap between the strip protrusion and the strip slot 327 is reduced, and the downwardly inclined squeezing force can prevent the possibility of the transformer 100 falling off upward, so that the transformer 100 can be more stably installed on the driving connection block 321, and its installation stability is improved. When the driving connection block 321 approaches the limiting connection plate 341, the two limiting top blocks 342 can approach the top of the transformer 100, and the bottom of the limiting top block 342 is formed with a top block inclined surface 345. The top block inclined surface 345 can make the bottom of the limiting top block 342 abut against the top of the transformer 100, which can further prevent the transformer 100 from falling off, and improve the stability of the transformer 100 during movement and testing.The limiting connecting plate 341 can drive the temperature detecting member 344 to abut against the side wall of the transformer 100, and can monitor the temperature of the transformer 100 in real time, and judge whether the transformer 100 meets the production requirements by the temperature change of the transformer 100 during the electrical test. In this case, the transformer 100 is fixed on the driving connecting block 321, and the cooperation of the strip groove 327 and the strip protrusion is used to make the transformer 100 firmly positioned on the transformer mounting groove 326, so as to ensure that the transformer 100 will not be displaced or detached during the test, thereby improving the stability of the installation. The transformer 100 can be moved by the cooperation of the driving threaded rod 24 and the moving support block 31. When the driving threaded rod 24 rotates, the moving support block 31 moves toward the second driving plate 23. The transformer 100 is moved to the right side, and then the transformer 100 is driven to move together. Through the coordinated action of the reset tension spring 322, the telescopic square block 323 and the flexible airbag 325, the gap between the strip protrusion of the transformer 100 and the strip slot 327 is reduced under the action of the downward extrusion force. The downward extrusion force can prevent the transformer 100 from slipping out upward, further improving the stability of the installation. The temperature detection member 344 is driven to abut against the side wall of the transformer 100 through the limit connecting plate 341, and the temperature change of the transformer 100 can be monitored in real time. By monitoring the temperature change of the transformer 100 during the electrical test, it can be judged whether the transformer 100 meets the production requirements, and the abnormal situation of the transformer 100 can be discovered in advance, ensuring the safety and quality of the production process.

[0047] When the driving connection block 321 moves and abuts against the limiting connection plate 341, the moving support block 31 can drive the driving connection block 321 and the limiting connection plate 341 to move in the direction of the second driving plate 23. The limiting connection plate 341 can drive the two trigger arc blocks 343 to move during the movement. When the trigger arc block 343 moves, it can abut against the bottom of the piston lifting rod 454, so that the piston lifting rod 454 moves upward. The piston lifting rod 454 can drive the piston moving block 453 to move upward. The upward movement of the piston moving block 453 can allow the gas at the top of the piston cavity 456 to enter the detergent storage box 451 through the gas through groove 457. The detergent in the detergent storage box 451 is squeezed by the gas and can The cleaning agent is squeezed to the top of the cleaning flexible cloth 44 near the end of the drive motor 21 through the penetration hole 431, so that the top of the cleaning flexible cloth 44 near the end of the drive motor 21 is slightly moistened, and the trigger arc block 343 is pressed against the piston lifting rod 454 to move upward with a small amplitude, so only a small amount of cleaning agent can be squeezed to the top of the cleaning flexible cloth 44 near the end of the drive motor 21, to prevent too much cleaning agent from entering the transformer 100 and causing a short circuit. In the process of the driving connection block 321 and the limiting connection plate 341 driving the transformer 100 to move, the pins of the transformer 100 will pass between the two cleaning flexible cloths 44, and the two cleaning flexible cloths 44 can wipe the pins of the transformer 100, thereby removing the dust on the pins of the transformer 100. And dirt is wiped off to prevent it from affecting the electrical test effect of the transformer 100. The pins of the transformer 100 will first pass through the cleaning flexible cloth 44 with a small amount of detergent. The detergent can improve the cleaning effect of the cleaning flexible cloth 44. The dry part of the cleaning flexible cloth 44 can further wipe the pins of the transformer 100 and prevent the detergent from adhering to the pins of the transformer 100, causing liquid to affect the test. When the trigger arc block 343 moves, it can resist the wavy surface 422 at the bottom of the cleaning lifting plate 42. The trigger arc block 343 makes the cleaning lifting plate 42 move up and down during the movement. The cleaning lifting plate 42 can drive the cleaning connection block 43 to move up and down, and the cleaning connection block 43 can drive two cleaning The flexible cloth 44 moves up and down, so that when the pin of the transformer 100 passes between the two cleaning flexible cloths 44, the up and down movement of the two cleaning flexible cloths 44 can wipe the pin of the transformer 100 up and down, and the bottoms of the two cleaning flexible cloths 44 are slightly close to each other and tilted to improve the cleaning effect during wiping. In this case, by moving the trigger arc block 343 and the cleaning lifting plate 42, the up and down movement of the cleaning connection block 43 and the cleaning flexible cloth 44 can be achieved, thereby effectively cleaning the pin of the transformer 100. Since the bottoms of the two cleaning flexible cloths 44 are slightly tilted, when wiping the pin of the transformer 100, the gap between the two cleaning flexible cloths 44 is tighter, and the pin of the transformer 100 can be wiped more effectively.The cleaning effect is improved, and too much cleaning agent can be prevented from entering the transformer 100 to cause a short circuit, thereby ensuring that the pins of the transformer 100 are fully cleaned to ensure the accuracy of the test results.

[0048] In another embodiment, during the process of triggering the arc block 343 against the wave surface 422, when the triggering arc block 343 abuts against the wave surface 422 from the high point to the low point so that the cleaning lifting plate 42 moves upward, the abutting force of the wave surface 422 can make the triggering arc block 343 have a tendency to move in the direction of the drive motor 21, thereby making the limiting connecting plate 341 have a tendency to move in the direction of the drive motor 21, and making the limiting connecting plate 341 tightly abut against the side wall of the driving connecting block 321, so that the protrusion of the flexible airbag 325 that is deformed and expanded passes through the telescopic limiting groove 332 and is tightly abutted against the strip protrusion of the transformer 100, thereby improving the friction between the strip protrusion and the flexible airbag 325, and preventing the cleaning lifting plate 4 2 moves upward to drive the two cleaning flexible cloths 44 to wipe the pins of the transformer 100, thereby improving the stability during wiping. When the trigger arc block 343 presses against the low point of the wave surface 422 to the high point so that the cleaning lifting plate 42 moves downward by its own gravity, after the trigger arc block 343 passes over the low point of the wave surface 422, the curvature of the wave surface 422 will cause the gravity of the cleaning lifting plate 42 to drive the trigger arc block 343 to slightly move away from the driving connection block 321, thereby causing the limiting connection plate 341 to slightly move away from the driving connection block 321. The movement of the limiting connection plate 341 can cause part of the gas in the deformed and expanded flexible airbag 325 to enter the telescopic circular groove 329 through the airbag through groove 331. That is, the inflated flexible airbag 325 will shrink slightly, thereby reducing the friction between the strip protrusion and the flexible airbag 325. At this time, the two cleaning flexible cloths 44 are wiped downward, which can drive the transformer 100 to be further pressed downward into the transformer mounting groove 326 to prevent a large gap between the transformer 100 and the transformer mounting groove 326. It can also prevent a large gap between the strip protrusion and the bottom of the strip card slot 327. If the gap is large, testing the transformer 100 is likely to cause the transformer 100 to shake or the test to be inaccurate. In this case, the arc block 343 is triggered to press the wave surface 422 from the high point to the low point to make the cleaning lifting plate 42 move upward, which can improve the strip protrusion and the flexible airbag 32 5, preventing the possibility of lifting the transformer 100 upward when the cleaning lifting plate 42 moves upward and drives the two cleaning flexible cloths 44 to wipe the pins of the transformer 100, thereby improving the stability of the cleaning process, and triggering the arc block 343 to press the wave surface 422 from the low point to the high point so that the cleaning lifting plate 42 moves downward by its own gravity, causing the flexible airbag 325 to shrink slightly, reducing the friction between the strip protrusion and the flexible airbag 325, and the downward wiping of the cleaning flexible cloth 44 can drive the transformer 100 to be pressed into the transformer mounting groove 326, thereby improving the contact tightness between the transformer 100 and the bottom of the transformer mounting groove 326, and preventing the transformer 100 from shaking or inaccurate testing during testing.

[0049] In one embodiment, when the pins of the transformer 100 come out from between the two cleaning flexible cloths 44, the dust and dirt on the pins of the transformer 100 have been cleaned, and the transformer 100 will continue to move forward. When the transformer 100 moves between the two clamping and stabilizing components 57, the driving motor 21 is stopped, and the linkage motor 16 is started. The linkage motor 16 drives one of the linkage shafts 152 to rotate, and the linkage shaft 152 is meshed with the tooth portion 154 of the other linkage shaft 152 through the tooth portion 154, so that the other linkage shaft 152 also rotates. The rotation directions of the two linkage shafts 152 are opposite. The linkage shaft 152 can drive the linkage gear 153 to rotate, and the linkage gear 153 can drive the linkage rack 54 to rotate. The linkage motor 16 is stopped, and the elastic force of the two compressed clamping springs 572 enables the two clamping plates 573 to clamp the transformer 100. The side walls of the clamping support block 571 can achieve a stable effect and avoid inaccurate test results due to vibration. When the two clamping movable plates 52 approach each other, the guiding connection block 551 and the conductive connection block 552 will also approach the pins of the transformer 100. The guiding connection block 551 can guide the pin ends of the transformer 100 through the wedge-shaped guiding groove 553 so that the ends of the pins of the transformer 100 can accurately enter the conductive through groove 554, so that the transformer 100 is electrically connected to the electrical test piece 56, and the electrical test piece 56 can test the electrical performance of the transformer 100 when it is working. The pin avoidance groove 575 on the clamping support block 571 is used to prevent the clamping support block 571 from abutting or squeezing the pins of the transformer 100, so as to prevent the pins of the transformer 100 from failing to enter the conductive through groove 554. The transformer 100 is tested, and the temperature change of the transformer 100 during the test is tested by the temperature detection component 344. In this case, the dust and dirt on the pins of the transformer 100 are cleaned to avoid the influence of these substances on the test results, thereby ensuring the accuracy of the test. The clamping of the two side walls of the transformer 100 is achieved by moving the clamping stabilizing component 57 and compressing the clamping spring 572 to avoid the change of its position due to vibration and other reasons, thereby ensuring the accuracy of the test results. The transformer 100 pins are accurately inserted into the conductive through slots 554 and electrically connected to the electrical test piece 56, and the electrical performance of the transformer 100 is tested. By using the pin avoidance slots 575, the clamping support block 571 is prevented from abutting or squeezing the pins of the transformer 100.By testing the temperature change of the transformer 100 during the test by the temperature detection element 344, the over-temperature situation can be discovered in time to avoid equipment damage and safety risks caused thereby.

[0050] After the electrical test of the transformer 100 is completed, the linkage motor 16 is driven in reverse to disengage the pins of the transformer 100 from the conductive groove 554, and the clamping of the two clamping plates 573 on the transformer 100 is cancelled. Then, the drive motor 21 is started in reverse to return the transformer 100 to its original position. When the transformer 100 returns to the starting position, the arc block supporting rod 11 can support the trigger arc block 343, so that the limit connecting plate 341 is away from the drive connecting block 321, thereby contacting the limit top block 342 to limit the top of the transformer 100, so that the operator can easily remove the transformer 100 from the drive connecting block 321.

The detergent storage box 451 is fixedly installed on the cleaning lifting plate 42 and the top of the cleaning connection block 43 near the end of the driving motor 21, the piston connection block 452 is fixedly installed on the side wall of the detergent storage box 451 facing the driving motor 21, the piston moving block 453 is slidably arranged in the piston cavity 456, the piston lifting rod 454 is fixedly installed on the bottom of the piston moving block 453, the two linkage fixed seats 151 are fixedly installed on the top of the installation connecting frame 13, the linkage rotating shaft 152 is rotatably installed in the middle of the two linkage fixed seats 151, and the linkage gear 153 is fixedly installed on the outer side wall of one end of the linkage rotating shaft 152 close to the other linkage rotating shaft 152, the two clamping sliding blocks 51 are respectively slidably installed on the ends of the two clamping rails 14, the clamping movable plate 52 is fixedly installed on the top of the two clamping sliding blocks 51, the rack connecting block 53 is fixedly installed on the bottom of the clamping movable plate 52, the linkage rack 54 is fixedly installed on one side wall of the rack connecting block 53, a number of pin guide blocks 55 are fixedly installed on one side wall of the clamping movable plate 52 facing the other clamping movable plate 52, the electrical testing piece 56 is fixedly installed on the top of the clamping movable plate 52, the clamping support block 571 is fixedly installed on one side wall of the clamping movable plate 52 facing the other clamping movable plate 52, the clamping spring 572 is fixedly installed on the side wall of the clamping buffer groove 574 close to the clamping movable plate 52, and the clamping plate 573 is fixedly installed on one end of the clamping spring 572 away from the clamping movable plate 52.

[0053] The present case can achieve the following: 1. The transformer 100 is fixed on the moving mechanism 30 by means of a clamping device, thereby avoiding accidental displacement during movement and ensuring the stability of the transformer 100. The cleaning mechanism 40 can clean and wipe the pins of the transformer 100, effectively removing dust and other dirt on the pins, ensuring the cleanliness of the pins, and helping to improve the conductive effect of the transformer 100 during electrical testing. By means of a linkage motor 16 and a clamping and stabilizing component 57, the two electrical testing mechanisms 50 are fixed around the transformer 100, effectively suppressing the influence of vibration and shaking and ensuring the accuracy of the electrical testing process. The operator can observe the electrical test results of the transformer 100 through an external device, including parameters such as input current, output current, input voltage and output voltage, so as to determine whether the transformer 100 is qualified, thereby improving convenience.

[0054] 2. By fixing the transformer 100 on the driving connection block 321 and using the cooperation of the strip groove 327 and the strip protrusion, the transformer 100 can be firmly positioned on the transformer installation groove 326, ensuring that the transformer 100 will not be displaced or detached during the test process, thereby improving the stability of the installation. By driving the threaded rod 24 and the mobile support block 31, the movement of the transformer 100 can be achieved. When the driving threaded rod 24 rotates, the mobile support block 31 moves toward the direction of the second driving plate 23, thereby driving the transformer 100 to move together. By resetting the tension spring 322, the telescopic square block 323 and the flexible gas The synergistic effect of the capsule 325 reduces the gap between the strip protrusion of the transformer 100 and the strip slot 327 under the action of the downward extrusion force. The downward extrusion force can prevent the transformer 100 from falling out upward, further improving the stability of the installation. The temperature detection component 344 is driven by the limiting connecting plate 341 to be pressed against the side wall of the transformer 100, so that the temperature change of the transformer 100 can be monitored in real time. By monitoring the temperature change of the transformer 100 during electrical testing, it can be determined whether the transformer 100 meets the production requirements, and abnormal conditions of the transformer 100 can be discovered in advance, thereby ensuring the safety and quality of the production process.

[0055] 3. By moving the trigger arc block 343 and the cleaning lifting plate 42, the cleaning connection block 43 and the cleaning flexible cloth 44 can be moved up and down, so that the pins of the transformer 100 can be effectively cleaned. Since the bottoms of the two cleaning flexible cloths 44 are slightly inclined, when wiping the pins of the transformer 100, the gap between the two cleaning flexible cloths 44 is tighter, which can more effectively wipe the pins of the transformer 100, improve the cleaning effect, and prevent too much detergent from entering the transformer 100 to cause a short circuit, thereby ensuring that the pins of the transformer 100 are fully cleaned to ensure the accuracy of the test results.

[0056] 4. By triggering the arc block 343 to press the high point of the wave surface 422 to the low point, the cleaning lifting plate 42 moves upward, which can increase the friction between the strip protrusion and the flexible airbag 325, and prevent the cleaning lifting plate 42 from moving upward to drive the two cleaning flexible cloths 44 to wipe the pins of the transformer 100 and lift the transformer 100 upward, thereby improving the stability of the cleaning process. By triggering the arc block 343 to press the low point of the wave surface 422 to the high point, the cleaning lifting plate 42 moves downward by its own gravity, causing the flexible airbag 325 to shrink slightly, reducing the friction between the strip protrusion and the flexible airbag 325. The downward wiping of the cleaning flexible cloth 44 can drive the transformer 100 to be pressed into the transformer mounting groove 326, thereby increasing the contact tightness between the transformer 100 and the bottom of the transformer mounting groove 326, and preventing the transformer 100 from shaking or inaccurate testing during testing.

[0057] 5. By cleaning the dust and dirt on the pins of the transformer 100, the influence of these substances on the test results is avoided, and the accuracy of the test is ensured. By moving the clamping and stabilizing component 57 and compressing the clamping spring 572, the two side walls of the transformer 100 are clamped to avoid changes in its position due to vibration and other reasons, thereby ensuring the accuracy of the test results. By accurately inserting the pins of the transformer 100 into the conductive groove 554 and electrically connecting it with the electrical test piece 56, the electrical performance test of the transformer 100 is performed. By using the pin avoidance groove 575, the clamping support block 571 is prevented from abutting or squeezing the pins of the transformer 100. The temperature change during the test of the transformer 100 is tested by the temperature detection piece 344, so that the over-temperature situation can be discovered in time to avoid equipment damage and safety risks caused thereby.

[0058] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
