The board body 2255 is mounted on the detection base 223.

[0032] The board 2255 is a circuit board that can be purchased on the market and is used to test the performance of the magnetic toroidal inductor 3. The first contact terminal 2251, the second contact terminal 2252, the third contact terminal 2253, and the fourth contact terminal 2254 are all plate-shaped structures, which facilitate contact with the pins of the magnetic toroidal inductor 3.

[0033] like Figure 8As shown, the inspection and handling structure 1 includes five inspection jaws 11, five Z-axis telescopic cylinders 12, an X-axis mobile structure 13, and a handling support 14. The five inspection jaws 11 are slidably mounted on the X-axis mobile structure 13 and are connected to the telescopic ends of the five Z-axis telescopic cylinders 12. The fixed ends of the five Z-axis telescopic cylinders 12 are all mounted on the X-axis mobile structure 13, which is mounted on the handling support 14.

[0034] The detection jaw 11 is used to grasp the magnetic ring inductor 3. The Z-axis telescopic cylinder 12 is used to drive the detection jaw 11 to move up and down. The X-axis moving structure 13 is used to drive the detection jaw 11 to move back and forth. The carrying bracket 14 is used to fix the X-axis moving structure 13.

[0035] like Figure 9 As shown, the detection clamp 11 includes two clamping arms 111, a first clamping cylinder 112, a sliding base 113, and a slide rail 114. Both clamping arms 111 are mounted on the first clamping cylinder 112, which is mounted on the sliding base 113. The sliding base 113 is slidably connected to the slide rail 114, which is mounted on the X-axis moving structure 13. The sliding base 113 is connected to the Z-axis telescopic cylinder 12.

The sliding base 113 and slide rail 114 guide the movement of the clamping arms 111.

[0036] The working process of the performance testing mechanism for the magnetic inductor 3 is described as follows: The first testing clamp 11 at the left end of the testing and handling structure 1 grasps the magnetic inductor 3 and places it onto the first leg pressing block 222 and the second leg pressing block 224 of the first testing fixture 22 of the testing and handling structure 1 of the performance testing mechanism 2. The four legs of the magnetic inductor 3 are inserted into the first test hole 2221, the second test hole 2222, the third test hole 2241, and the fourth test hole 2242, respectively. The second clamping cylinder 221 drives the first leg pressing block 222 and the second leg pressing block 224 to close. The first leg pressing block 222 pushes the first contact end 2251 and the second contact end 2252 of the testing circuit board 225 toward the right two legs of the magnetic inductor 3. Simultaneously, the second leg pressing block 224 pushes the third contact end 2253 and the fourth contact end 2254 of the testing circuit board 225 toward the left two legs of the magnetic inductor 3. After the test circuit board 225 has tested the magnetic inductor 3, the second clamping cylinder 221 drives the first leg push block 222 and the second leg push block 224 to open. The first contact end 2251, the second contact end 2252, the third contact end 2253, and the fourth contact end 2254 all release the four legs of the magnetic inductor 3. The second test clamp 11 on the left end of the test and handling structure 1 grabs the magnetic inductor 3 that has been tested by the first test fixture 22. At the same time, the first test clamp 11 on the left end grabs another magnetic inductor 3. The Z-axis telescopic cylinder 12 drives the test clamp 11 upward, and the X-axis moving structure 13 drives the five test clamps 11 to the right. The magnetic inductor 3 of the first test clamp 11 on the left end is placed on the first test fixture 22 on the left end. At the same time, the second test clamp 11 on the left end places the magnetic inductor 3 on the second test fixture 22 on the left end. The first and second test fixtures 22 simultaneously test two magnetic ring inductors 3. Similarly, each magnetic ring inductor 3 is tested for different properties by the four test fixtures 22, including withstand voltage, inductance, leakage voltage, and resistance. The fifth test clamp 11 of the test handling structure 1 grabs the magnetic ring inductor 3 on the fourth test fixture 22. The Z-axis telescopic cylinder 12 drives the test clamp 11 upward, and the X-axis moving structure 13 drives the test clamp 11 to the right, moving the tested magnetic ring inductor 3 to the right side of the performance test structure 2.
