At this point, the monitoring process for one cable ends. Meanwhile, the wire feeding unit 14 controls the motor to drive the first wire feeding wheel and the second wire feeding wheel to rotate through calculation and analysis of data of the encoder 111, so as to drive the cable to move, and the moving speed of the cable is synchronized with the feeding speed (including the advancing speed and the retreating speed) of the cutting and stripping equipment.

When the cable contacts or leaves the second sensing light curtain, the image acquisition unit 12 controls the industrial camera 121 to photograph according to the trigger signal sent by the second sensing light curtain, and the peeling length of each layer on the front end or the tail end of the cable is acquired through the image photographed by the industrial camera 121. And comparing the obtained peeling length and the obtained cable length with the standard length, judging whether the peeling length and the cable length are the standard length, if so, determining that the product is a qualified product, and if not, determining that the product is an unqualified product.

Wherein the database may be provided in a memory connected to the processor, or may be provided in a remote control device connected thereto.
In this embodiment, in order to prevent the cable length measurement failure caused by the false trigger signal sent by the first sensing light curtain due to the cable retraction, it is necessary to determine whether the difference between the length data input by the cable and the first peeling length L1, the second peeling length L2, and the peeling space length on the cable is greater than the sum of the distance from the cutter to the right end face of the cable cutting and peeling machine 2 and the distance from the right end face of the cable cutting and peeling machine 2 to the first sensing light curtain, and if so, the cable length is calculated according to the actually measured pulse count of the encoder 111 in the interval formed by the rising edge and the falling edge of the first sensing light curtain every time. If not, calculating the length of the cable according to the measured pulse count of the encoder 111 in the interval formed by the second rising edge and the second falling edge of the first induction light curtain. The first peeling length L1 is the length of the cable with the innermost layer exposed at the front end, the second peeling length L2 is the length of the cable with the innermost layer exposed at the front end, and the first sensing light curtain generates a trigger signal of a rising edge signal and a falling edge signal.
In this embodiment, the cable peeling quality monitoring device 1 may be further connected to a cable sorting device, and after determining that the cable passing through the cable peeling quality monitoring device 1 is an unqualified product, the information that the cable is an unqualified product is sent to the cable sorting device, and the cable is transferred to an unqualified place by the cable sorting device to separate the unqualified product from a qualified product.
