[0029] Before testing, the wire core to be tested can be wound around the pay-off roller 6, and one end of the wire core can be connected to the take-up roller 15 through the internal detection device of the mobile platform 13. Then, the motor device in the slide 11 is started to drive the screw rod 12 to rotate, and the rotation of the screw rod 12 can drive the mobile platform 13 to move back and forth inside the slide 11.

After the detection is completed, the wire core can be automatically gathered on the surface of the take-up roller 15. After the take-up roller 15 is taken out, the cutting work can be carried out to remove the unqualified sections in the wire core.

During continuous detection, if an unqualified wire core section is found, the marking platform 20 at the rear end of the moving platform 13 can be controlled by the signal processing platform 18, and the unqualified wire core section can be sprayed and marked by the nozzle 24 at the lower end of the marking platform 20. The dye can be sprayed onto the surface of the wire core 10 between the upper fixed plate 23 and the spraying plate 25 through the upper fixed plate 23, and the spraying plate 25 can prevent the dye from scattering onto the workbench during the spraying process, which is convenient for subsequent cleaning.

[0039] Starting the electric telescopic rod 22 can control the upper fixed plate 23 and the spray plate 25 to move up and down, which is convenient for adjusting the distance between the wire core 10 and the nozzle 24 on the surface of the spray plate 25. After the detection is completed, the wire core can be automatically gathered on the surface of the take-up roller 15. After taking out the take-up roller 15, cutting work can be carried out to remove unqualified sections in the wire core, thereby improving work efficiency. When the take-up roller 15 rotates, the material is automatically collected, which is convenient for continuous automatic detection. This device can perform continuous automatic loading and detection. During the detection, unqualified wire core sections can be sprayed and marked, which is convenient for subsequent cutting and processing of the wire core and improves work efficiency.
