Description

Technical Field

[0001] The invention relates to a twisted-pair cable posture adjustment method and a twisted-pair cable processing method. Background Art

[0002] In the prior art, in order to electrically connect one end of a twisted-pair cable to a terminal of a connector, it is necessary to first remove the outer sheath of one end of the twisted-pair cable to expose the inner twisted-pair core wires. The twisted-pair core wires are then unwound and straightened; finally, the straightened twisted-pair core wires are adjusted to a predetermined posture by rotating the twisted-pair cable, for example, to a horizontal posture (i.e., the center line of the twisted-pair core wires is horizontal) or a vertical posture (i.e., the center line of the twisted-pair core wires is vertical) to facilitate subsequent processes. In the prior art, the twisted-pair core wires can be adjusted to a predetermined posture based on visual inspection only after the outer sheath is stripped off and the twisted-pair core wires are straightened. However, the adjustment angle required to rotate the twisted-pair core wires to the predetermined posture cannot be accurately known before the outer sheath is stripped off and the twisted-pair core wires are straightened. This brings many inconveniences to the processing of the twisted-pair cable and reduces the processing efficiency and accuracy of the twisted-pair cable. Summary of the Invention

[0004] According to one aspect of the present invention, a method for adjusting the posture of a twisted pair cable is provided. The method for adjusting the posture of a twisted pair cable comprises the following steps:

[0005] S11: capturing an image of the end face of the twisted pair cable;

[0006] S12: Calculating the posture of the twisted pair core wires of the twisted pair cable at the end surface according to the captured image;

[0007] S13: calculating an initial posture of the twisted pair core wire at a cutting position of the outer sheath to be stripped based on the posture of the twisted pair core wire at the end surface, the length of the outer sheath to be stripped from the twisted pair cable, and the lay length of the twisted pair cable;

[0008] S14: calculating an adjustment angle by which the twisted pair cable needs to be rotated according to an initial posture of the twisted pair core wires at a cutting position of the outer coating to be stripped and a predetermined posture of the twisted pair core wires at a cutting position of the outer coating to be stripped; and

[0009] S15: rotating the twisted pair cable around its central axis by the adjustment angle, so that the posture of the twisted pair core wires at the cutting position of the outer sheath to be stripped is adjusted to the predetermined posture.

[0010] According to an exemplary embodiment of the present invention, in step S11, an image of the end surface of the twisted pair cable is captured along the axial direction of the twisted pair cable using a camera disposed in front of the end surface of the twisted pair cable.

[0011] According to another exemplary embodiment of the present invention, in step S12, a first angle between a center line connecting the twisted pair cores of the twisted pair cable and a predetermined orientation is calculated based on the captured image of the end face of the twisted pair cable to determine the posture of the twisted pair cores of the twisted pair cable at the end face.

[0012] According to another exemplary embodiment of the present invention, in step S13, a second angle between a center line of the twisted pair core wires of the twisted pair cable at the cutting position of the outer sheath to be stripped and the predetermined orientation is calculated according to the following formula to determine the initial posture of the twisted pair core wires of the twisted pair cable at the cutting position of the outer sheath to be stripped,

[0019] According to another exemplary embodiment of the present invention, in step S14, the adjustment angle is set to the second angle.

[0020] According to another exemplary embodiment of the present invention, in step S15, the twisted pair cable is rotated around its central axis by the second angle so that the center line of the twisted pair core wires of the twisted pair cable at the cutting position of the outer sheath to be stripped is in the predetermined orientation, thereby adjusting the posture of the twisted pair core wires of the twisted pair cable at the cutting position of the outer sheath to be stripped to the predetermined posture.

[0021] According to another exemplary embodiment of the present invention, the predetermined orientation is a horizontal orientation or a vertical orientation perpendicular to a central axis of the twisted pair cable.

[0026] S23: straightening the exposed twisted pair core wires of the twisted pair cable so that a center line of the exposed twisted pair core wires of the twisted pair cable is parallel to the predetermined orientation.

[0027] According to another exemplary embodiment of the present invention, in step S21 , the twisted pair cable is clamped by a cable clamp and the posture of the twisted pair cable is adjusted to the predetermined posture by rotating the cable clamp.

[0028] According to another exemplary embodiment of the present invention, step S22 includes:
