[0024] Among them, the detection head includes a cylinder frame 31, a lifting cylinder 32, a lifting block 33 and an electrode block 34. The lifting cylinder 32 is fixed on the cylinder frame 31. The lifting block 33 is fixed on the active end of the piston rod of the lifting cylinder 32. The electrode block 34 is connected to the lifting block 33. Detection probes 35 are arranged at intervals on the electrode block 34. One end of the detection probe 35 is connected to the duplex current measuring instrument 41 through a connecting line, and the other end contacts and separates from the ring body of the lead 521 through a lifting method at the detection head.

[0031] Step 1: Place the tube core 5 to be tested horizontally on the lower fixture 2, and place the lead wire on the metal pad 231;

[0032] Step 2: Press the control button, and when the turntable 1 rotates 90 degrees, that is, when the tube core 5 to be tested is located directly under the test head, the turntable 1 pauses;

[0033] Step 3: The lifting plate 33 of the detection head descends under the action of the lifting cylinder 32, so that the detection probe 35 is fully in contact with the ring body of the lead wire, and the detection begins;

[0034] Step 4: The duplex current measuring instrument 41 detects the current flowing through the two ends of the filament of the tube core 5 under a preset voltage, and displays the detected data on the display screen of the duplex current measuring instrument 41; if the data is within the range of 250-350, it indicates that the test is qualified; if the data is not within the range of 250-350, it indicates that the test is unqualified, and the alarm light 42 lights up red; the test is completed.

[0035] Step 5: The lifting plate 33 of the detection head is acted upon by the lifting cylinder 32 to separate the detection probe 35 from the lead 521. The turntable 1 rotates 90 degrees and then pauses. The operator removes the detected tube core 5 and places them separately according to whether they are qualified or not.

[0036] Repeat steps 1-5 until all the dies 5 to be inspected are inspected.
