Specifically, when the wire arrangement interval is detected, the control unit 4, the wire receiving position detecting module 21 and the first turn detecting module 31 are all in an on state, and meanwhile, the first turn detecting module 31 starts counting the turns when the diamond wire saw 6 passes through the wire receiving position detecting module 21 for the first time, then continues counting the turns when the diamond wire saw 6 passes through the wire receiving position detecting module 21 for the second time, and stops counting when the diamond wire saw 6 passes through the wire receiving position detecting module 21 for the third time. At this time, the diamond wire saw 6 winds two layers on the take-up pulley 11, which is equivalent to the width of the two take-up pulleys 11, and the winding distance of the winding period is obtained by dividing the width of the two take-up pulleys 11 by the number of the first turns counted by the first turns detecting module 31 by twice, so as to realize the winding and winding detection of the winding period.

In some embodiments, the diamond wire saw wire winding machine further comprises a wire winding and arranging screw 7, wherein the wire winding and arranging screw 7 is arranged on the wire winding side 111; the wire winding and arranging screw rod 7 comprises a screw rod nut 71 and a screw rod 72, and the screw rod nut 71 is slidably arranged on the screw rod 72; the wire-rewinding position detecting module 21 includes: a first detection probe 211, the first detection probe 211 being located at one side of the screw 72; the position identifying member 212 is provided on the lead screw nut 71 and moves on the lead screw 72 along with the lead screw nut 71, and the position identifying member 212 is used for triggering the detection signal of the wire winding position detecting module 21.

Starting the winding machine, when the diamond wire saw 6 contacts with the second detection probe 221 for the first time, at this time, the control unit 4 starts counting the number of turns of the paying-off wheel 12 as a counting start point of a winding cycle, at this time, the diamond wire saw 6 is located at the third side 122, then the diamond wire saw 6 gradually pays out to the fourth side 123, reaches the fourth side 123, and then pays out to the third side 122 in reverse, when the diamond wire saw 6 contacts with the second detection probe 221 for the second time, that is, the diamond wire saw 6 reaches the third side 122, the diamond wire saw 6 serves as an end point of the winding cycle, and the programmable controller counts counting nodes of the number of turns of the paying-off wheel 12, at this time, the paying-off wheel 12 goes through two layers of paying-off, so that the winding interval of the paying-off wheel 12 is calculated according to the twice of the wheel width and the counted number of turns of the paying-off wheel 12. Meanwhile, the number of turns is cleared and reckoned as calculation data of the next winding displacement period. At this time, the second contact of the diamond wire saw 6 with the second inspection probe 221 serves as the start point of the next wire arrangement cycle, and the diamond wire saw 6 corresponding to the next wire arrangement cycle is first contacted with the second inspection probe 221.

In the embodiment of the application, the wire paying-off and arranging line distance detection can be used for paying-off detection on the winding wheel 11 after winding is completed, so as to detect whether the wire paying-off is abnormal or not in the earlier stage.

In addition, the winding position detection module 21 and the first turn detection module 31 of the winding machine are used for winding and arranging wire detection, and the paying-off position detection module 22 and the second turn detection module 32 are used for paying-off and arranging wire detection, so that the winding machine can also perform paying-off and arranging wire detection and winding and arranging wire detection simultaneously.

Thus, whether the wiring line is different or not can be visually judged by synchronously comparing the two ends.

In some embodiments, the method further comprises the step of judging whether the flat cable is abnormal or not: judging whether the wire arrangement interval of the current wire arrangement period is equal to the wire arrangement interval of the previous wire arrangement period, if so, the wire arrangement is normal, and if not, the wire arrangement is abnormal; or,

The application not only can detect the wire arrangement distance of the paying-off wheel 12 and the wire collecting wheel 11, but also can judge whether the wire arrangement distance of the current wire arrangement period is abnormal or not by comparing the wire arrangement distance in two adjacent wire arrangement periods, so that the wire arrangement abnormality can be found in time by monitoring the wire arrangement distance in real time, and further the wire arrangement treatment can be correspondingly carried out. In addition, the application can integrate the line intervals corresponding to the line intervals to form a time-line interval curve, presetting a threshold range of the line intervals, if the line intervals are normal, the fluctuation range of the line interval curve is within the threshold range, and if the line intervals are abnormal, the fluctuation range of the line interval curve exceeds the threshold range.
