[0040] The detection mechanism is arranged on one side of the clamping mechanism, and comprises a first detection assembly and a second detection assembly for detecting the length of the wire skin and the number of the wire core 12 of the wire to be detected respectively.

[0041] The dual-camera wire detection device of the utility model aims at realizing the detection of the length of the wire skin and the number of the wire core 12 of the wire to be detected. The two ends of the wire to be detected are fixed by the clamping mechanism, so that the position of the wire is fixed during the detection process. The first detection assembly in the detection mechanism detects the length of the wire skin by the first camera 6, and the first driving assembly 5 can adjust the radial distance between the first camera 6 and the wire to be detected, so that the first camera 6 can clearly capture the wire with different diameters and obtain the wire image to accurately detect the wire skin. The second detection assembly detects the number of the wire core 12 by the second camera 8, and the second driving assembly 4 can adjust the axial distance between the second camera 8 and the wire to be detected, so as to clearly capture the wire with different diameters from the appropriate axial distance and identify the number of the wire core 12.

[0042] The installation angle of the first camera 6 should be perpendicular to the axis of the wire to be detected, so as to clearly capture the circumferential surface of the wire, thereby accurately detecting the length of the wire skin. The installation direction of the second camera 8 is parallel to the axis of the wire to be detected, so as to capture the axial section of the wire, thereby detecting the number of the wire core 12. The first camera 6 captures the circumferential image of the wire to be detected, and the second camera 8 captures the axial section image of the wire to be detected, and then transmits the image signal to the image acquisition card. The image acquisition card converts the analog signal into a digital signal and transmits it to the computer for processing. Specifically, the acquisition card identifies the edge of the wire skin through an edge detection algorithm based on the image collected by the first camera 6, and then calculates the circumference of the wire skin according to the pixel size in the image and the known actual size ratio relationship, and further calculates the length of the wire skin according to the circumferential length.
