Description

Technical Field

[0001] This utility model relates to the field of inductor processing technology, specifically to a detection device for a magnetic ring inductor. Background Technology

[0002] Ferrite cores, also known as magnetic rings, become magnetic ring inductors when coils are wound around them. They are commonly used anti-interference components in electronic circuits, effectively suppressing high-frequency noise. Magnetic ring inductors exhibit different impedance characteristics at different frequencies; generally, the impedance is very low at low frequencies, and increases sharply as the signal frequency rises. Because the number and specifications of the coils wound on the magnetic ring vary, all manufactured magnetic ring inductors require testing. Existing small-scale magnetic ring inductor testing devices can only test them one by one, resulting in slow testing efficiency. Utility Model Content

[0003] To address the low testing efficiency of existing magnetic ring inductance testing devices, this invention provides a magnetic ring inductance testing device. The specific technical solution of this invention is as follows:

[0004] A testing device for a magnetic ring inductor includes: a test bench and a testing machine disposed on the test bench. The test bench includes a probe mechanism, a placement stage, a first cylinder, and a second cylinder. The first cylinder is vertically downward disposed in the test bench. The probe mechanism is vertically downward disposed and connected to the piston rod of the first cylinder. The probe mechanism is electrically connected to the testing machine. The second cylinder is horizontally forward disposed. The placement stage is movably disposed on the test bench and connected to the piston rod of the second cylinder. The placement stage is provided with a plurality of placement seats for placing the magnetic ring inductor, and the placement seats are arranged on the placement stage.

[0005] Furthermore, the placement base includes a base plate and a support column, a baffle, a partition, and an electrode block disposed on the base plate. The support column is disposed in the baffle, and a receiving cavity for placing the magnetic ring inductor is provided between the support column and the baffle. The electrode block is disposed on the outside of the baffle and is used to place the electrodes of the magnetic ring inductor. The partition is disposed between the electrode blocks.

[0006] Furthermore, grooves are provided on the side baffles of the placement seat.

[0007] Furthermore, the electrode block is provided with a placement opening for placing the magnetic ring inductor, and the heights of the placement openings of the electrode blocks on both sides of the partition are different.

[0008] Furthermore, the probe mechanism includes a pressure plate and probes. The pressure plate is connected to the piston rod of the first cylinder, and the probes are vertically downward mounted on the pressure plate, with each probe positioned directly above the electrode block.

[0011] Compared with existing technologies, the advantages of this invention are as follows: The testing device described in this application has multiple placement seats on the placement platform, enabling the testing device to test multiple magnetic ring inductors simultaneously, thus improving the testing efficiency of magnetic ring inductors. The testing device controls the placement platform to move forward on the testing platform via a second cylinder, facilitating the placement and removal of magnetic ring inductors by operators; the testing device also controls the placement platform to retract to directly below the probe mechanism before testing the magnetic ring inductors, ensuring that the magnetic ring inductors are tested away from operators, thereby improving production safety.

[0023] like Figures 1 to 5As shown, a testing device for a magnetic ring inductor includes: a test platform 1 and a testing machine 2 disposed on the test platform 1. The test platform 1 includes a probe mechanism 3, a placement platform 4, a first cylinder 5, and a second cylinder 6. The first cylinder 5 is vertically downward disposed in the test platform 1. The probe mechanism 3 is vertically downward disposed and connected to the piston rod of the first cylinder 5. The probe mechanism 3 is electrically connected to the testing machine 2. The probe mechanism 3 moves up and down under the control of the first cylinder 5. The second cylinder 6 is horizontally forward disposed. The placement platform 4 is movably disposed on the test platform 1 and connected to the piston rod of the second cylinder 6. The placement platform 4 moves back and forth on the testing device under the action of the second cylinder 6. The placement platform 4 is provided with a plurality of placement seats 7 for placing the magnetic ring inductor 21. The placement seats 7 are arranged on the placement platform 4. When testing the magnetic ring inductor 21, the testing device can simultaneously energize the magnetic ring inductor 21 to test multiple magnetic ring inductors 21, or it can sequentially energize the magnetic ring inductors 21 to test multiple magnetic ring inductors 21, making it highly practical.

[0024] In one embodiment, the placement base 7 includes a base plate 8 and a support column 9, a baffle 10, a partition 11, and an electrode block 12 disposed on the base plate 8. The support column 9 is disposed in the baffle 10, and a receiving cavity 13 for placing the magnetic ring inductor 21 is provided between the support column 9 and the baffle 10. The electrode block 12 is disposed on the outside of the baffle 10 and is used to place the electrodes of the magnetic ring inductor 21. The partition 11 is disposed between the electrode blocks 12. When the detection device is working, the magnetic ring inductor 21 is placed in the receiving cavity 13, the electrodes of the magnetic ring inductor 21 are placed in the electrode blocks 12, and the partition 11 is used to separate the two electrode blocks 12 to prevent the magnetic ring inductor 21 from short-circuiting during testing.

[0025] In one embodiment, the side baffles 10 of the placement seat 7 are provided with grooves 14. The grooves 14 facilitate the operator to place the magnetic ring inductor 21 on or remove it from the placement seat 7.

[0026] In one embodiment, the electrode block 12 is provided with a placement opening 15 for placing the magnetic ring inductor 21, and the heights of the placement openings 15 on both sides of the partition 11 are different. Because the electrodes of the magnetic ring inductor 21 are respectively located on both sides of the magnetic ring, when the magnetic ring inductor 21 is placed flat on the placement base 7, the heights of the two electrodes are different, and the placement openings 15 of different heights can make the magnetic ring inductor 21 more stably placed on the placement base 7.

[0027] In one embodiment, the probe mechanism 3 includes a pressure plate 16 and probes 17. The pressure plate 16 is connected to the piston rod of the first cylinder 5, and the probes 17 are vertically downward mounted on the pressure plate 16, positioned directly above the electrode block 12. During testing, the first cylinder 5 controls the probe mechanism 3 to press down, causing the probes 17 to press onto the electrode block 12, and then power is applied for testing.

[0028] In one embodiment, the lower end of the placement platform 4 is provided with a slider 18, and the lower end of the slider 18 is provided with a guide rail 19. The placement platform 4 is fixedly connected to the slider 18, and the slider 18 is movably mounted on the guide rail 19.

[0029] In one embodiment, the test bench 1 is provided with a bracket 20, and the first cylinder 5 is vertically mounted on the bracket 20.

[0030] The testing device described in this application has multiple placement seats 7 on the placement stage 4, enabling the testing device to test multiple magnetic ring inductors 21 simultaneously, thus improving the testing efficiency of the magnetic ring inductors 21. The testing device controls the placement stage 4 to move forward on the test stage 1 via the second cylinder 6, facilitating the placement and removal of the magnetic ring inductors 21 by the operator; the testing device also controls the placement stage 4 to retract to directly below the probe mechanism 3 before testing the magnetic ring inductors 21, ensuring that the magnetic ring inductors 21 are tested away from the operator, thereby improving production safety.
