Description

Technical Field

[0001] The utility model relates to the technical field of transformer testing devices, in particular to a transformer component testing device. Background Art

[0002] After the coils are wound, transformer components must undergo multiple tests to ensure their performance is perfect. To improve the efficiency of batch testing, assembly lines are often used to perform multiple tests in sequence. However, using conventional conveyor belts makes it difficult to ensure that the transformer components to be tested are precisely aligned with the test equipment. Therefore, it is difficult to achieve fully automated testing and requires a certain amount of manual intervention. When periodically conveyed by a strip structure, the components to be tested have a temporary lack of limit and are easily displaced by external forces. When the strip structure is still running according to the set program, the transformer components will not be able to align with the strip structure, resulting in damage to the transformer components. Summary of the Invention

[0005] Furthermore, the transfer mechanism includes a plug-in plate structure, and a limit slot is provided on the side of the plug-in plate structure close to the guide slot. The plug-in plate structure moves laterally towards or away from the component to be tested. When the plug-in plate structure moves laterally to above the guide slot, the component to be tested is correspondingly snapped into the limit slot.

[0006] Furthermore, the test module includes a plurality of test probes, wherein the plurality of test probes are respectively mounted correspondingly to the plurality of pole pins on the component to be tested, and two of the plurality of test probes are electrically connected to the testing equipment.

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 A transformer component testing device includes a guide slot 1 and a transfer mechanism 2. A plurality of workstations are arranged along the guide direction of the guide slot 1, and each workstation is correspondingly provided with a transfer mechanism 2. The transfer mechanism 2 is used to drive the component to be tested 3 on the front workstation to slide along the guide slot 1 to its corresponding workstation; the plurality of workstations include a loading position 4, a detection position 5 and a unloading position 6. A plurality of detection positions 5 are continuously arranged between the loading position 4 and the unloading position 6, and the detection position 5 is provided with a test module. The guide slot 1 and the transfer mechanism 2 cooperate to constrain the test position of the component to be tested 3, and the test module descends and cooperates with the pole needle sleeve of the component to be tested 3.

[0015] This solution utilizes the coordinated action of multiple transfer mechanisms to achieve sliding coordination between the transformer assembly and the guide chute, thereby transporting the transformer assembly to be tested from the loading position to multiple testing positions in sequence, thereby continuously completing multiple tests on the transformer assembly and finally transporting it from the unloading position. At each testing position, the transfer mechanism constrains the relative position of the transformer assembly in the guide chute, ensuring that the test module and the transformer assembly's pins are aligned vertically, thereby ensuring the accuracy of the alignment test and preventing misalignment from affecting the test results and damaging the pins.

[0016] The transfer mechanism 2 includes a plug-in plate structure 21, which is provided with a limit stop 22 on one side of the plug-in plate structure 21 near the guide slot 1. When the plug-in plate structure 21 is laterally moved toward or away from the component under test 3, the component under test 3 is correspondingly engaged with the limit stop 22 when the plug-in plate structure 21 is moved above the guide slot 1. The size of the limit stop is compatible with the size of the transformer assembly, and can better cooperate with the guide slot to constrain the position of the transformer assembly, ensuring the alignment accuracy of the test module and the pole needle.

[0017] The test module includes a plurality of test probes 51 , wherein the plurality of test probes 51 are respectively mounted correspondingly to the plurality of poles on the component under test 3 , and two of the plurality of test probes 51 are electrically connected to a testing device.

[0018] The test probe adopts an insertable structure, with a port for inserting a pole needle at the end. After the pole needle is inserted, it contacts the internal conductor, thereby connecting the transformer coil to the test circuit. After the test probe and the pole needle are inserted and matched, the lower end face of the probe is pressed against the upper end face of the transformer assembly, which also limits the position of the transformer assembly on the guide slide. It can realize the positioning of the transformer assembly when the two transfer mechanisms are connected, ensuring that the limit bayonet of the rear transfer mechanism can accurately engage with the transformer assembly, avoiding the displacement of the transformer assembly during the conversion of the matching transfer mechanism, which may cause the transformer assembly to be squeezed and damaged or fly off the guide slide. The test probe connected to the test circuit can be adjusted according to the position of the pole needle wound on the transformer coil.

[0019] The detection position 5 is equipped with multiple test modules, arranged at regular intervals along the guide direction. These modules are fixedly mounted on a common test plate 52, which is connected to the bottom end of the lifting rod of the lifting mechanism. The insert plate structure 21 is provided with multiple position-limiting notches 22 at locations corresponding to the test modules. This allows for simultaneous testing of multiple transformer components, effectively improving testing efficiency. However, the number and spacing of the test modules must be consistent at each test position.

[0020] The plurality of transfer mechanisms 2 are staggered on both sides of the guide slot 1. This allows two adjacent transfer mechanisms to be moved to align on both sides of a test position. The transfer mechanisms on both sides cooperate to engage with the limit snap-in of the rear transfer mechanism before the transformer assembly is completely disengaged from the limit snap-in of the front transfer mechanism, thereby ensuring accurate and correct handover of the transformer frame between the front and rear adjacent transfer mechanisms, further preventing damage to the transformer assembly.

[0021] The bottom surface of the test board 52 is provided with a distance sensing module. The distance sensing module's distance signal output terminal is electrically connected to the corresponding workstation's lifting mechanism and the control signal receiving terminal of the lateral movement drive device of the plug-in board structure 21. The distance signal feedback controls the operation of the two actuators at the current test position. The spacing between the test board and the plug-in board structure when the test probe is lowered into position is used as a reference value. When this reference value is first sensed after the test board is lowered, the transfer mechanism corresponding to the current test position is retracted. When this reference value is sensed again, the test board is raised, completing a test operation.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
