[0002] A magnetic core is a core component made of a magnetic material, usually used in transformers, inductors and certain specific electronic devices. Its main function is to provide a closed magnetic loop so that the magnetic field can be effectively conducted in it, thereby improving the efficiency and performance of the device. In electronic devices, the magnetic core can help concentrate the magnetic field, enhance the magnetic induction intensity, reduce the required excitation current, reduce the volume of electromagnetic components, and achieve magnetic coupling equivalent to electrical coupling.

[0003] During the production process of magnetic cores, a testing jig is needed to test the magnetic cores. Although the existing testing jigs can perform relatively accurate testing.

[0004] However, since there are many items that need to be inspected after the magnetic core is produced, the existing inspection jigs can only detect a few items. As a result, when inspecting the magnetic core, the staff needs to constantly transfer the position of the magnetic core to different types of inspection jigs, which wastes too much time and is more troublesome, thereby reducing the inspection efficiency of the magnetic core and its practicality is poor. Therefore, a magnetic core inspection jig is proposed to solve the above problems. Utility Model Content

When in use, the staff first needs to place the magnetic core to be tested into the discharge trough 15 on the top of the mobile platform 14. After the placement is completed, the electric telescopic rod 13 is started to drive the mobile platform 14 to move laterally inside the fixture box 1, thereby changing the position of the magnetic core so that it is directly below the electromagnetic detection coil 9, the pressure block 11 and the appearance camera 12, respectively, so as to perform electromagnetic induction detection, strength detection and appearance detection respectively.

[0024] Furthermore, compared with the currently available testing fixtures, triple-item testing is achieved, which can perform electromagnetic induction testing, strength testing and appearance testing respectively, so that the staff does not need to constantly transfer the position of the magnetic core to different types of testing fixtures, thus avoiding wasting too much time. At the same time, it saves time and effort, thereby improving the detection efficiency of the magnetic core and having good practicality.

[0025] Among them, the outer diameters of the first mounting frame 4, the second mounting frame 5 and the third mounting frame 6 are all the same, the sleeve rod 16 is slidably connected to the mobile platform 14, and the mobile platform 14 is rotatably connected with moving wheels 17 around the bottom, and the inner bottom wall of the fixture box 1 is provided with a slide groove 18, and the moving wheel 17 is slidably connected to the slide groove 18.

After the placement is completed, the electric telescopic rod 13 is started to drive the mobile platform 14 to move laterally inside the fixture box 1, thereby changing the position of the magnetic core so that it is directly below the electromagnetic detection coil 9, the pressure block 11 and the appearance camera 12, respectively, so as to perform electromagnetic induction detection, strength detection and appearance detection respectively. Among them, when the magnetic core is directly below the electromagnetic detection coil 9, the staff needs to stop the electric telescopic rod 13, and then start the first electric push rod 7, so as to drive the electromagnetic detection through the push plate 8. The coil 9 moves vertically downward so that the electromagnetic detection coil 9 is in close contact with the magnetic core, and then electromagnetic induction detection is performed. In addition, when the magnetic core is located directly below the electromagnetic detection coil 9, the staff needs to stop the electric telescopic rod 13 and then start the second electric push rod 10. The second electric push rod 10 can drive the pressure block 11 to move vertically downward, thereby continuously pressing the magnetic core to perform strength detection, and the pressure sensor 24 can detect the strength value, which is convenient for the staff to read. Finally, when the magnetic core is located directly below the electromagnetic detection coil 9, the appearance photography device 12 is started to take a photo of the appearance of the magnetic core for detection.
