Disclosure of Invention
In order to solve the technical problems that in the prior art, sunlight directly influences the receiving sensitivity of an infrared receiving tube to a modulation signal emitted by an infrared emitting tube, and the wire core detection is in error, so that the wire core and a cutter are damaged; the invention aims to provide a full-automatic peeling device for a high-voltage live cable, which is characterized in that two wire core detection sensor assemblies are arranged on two sides of a cutter respectively, infrared modulation signals are outwards emitted by the wire core detection sensor assemblies by utilizing different reflectivities of the wire core and the wire skin, the infrared modulation signals reflected by the wire core or the wire skin are rotated into direct current levels and then subjected to difference value operation, the influence of sunlight on the wire core detection sensor assemblies is removed, and whether the wire core is peeled or not is accurately judged.
In order to achieve the above purpose, the present invention is realized by the following technical scheme: a rotation mechanism that rotates feeding in a wire length direction; the cutter is arranged on the rotating mechanism; the wire core detection sensor assembly is used for detecting the peeling depth; the control circuit is used for judging the peeling state and controlling the movement of the rotating mechanism and the cutter; the wire core detection sensor assemblies are two groups and are respectively arranged on two sides of the cutter along the length direction of the cable; the wire core detection sensor assembly comprises at least one infrared transceiver group consisting of at least one infrared transmitting tube and one infrared receiving tube; the infrared receiving tube converts an infrared modulation signal sent by an infrared transmitting tube reflected by the cable into a direct current level; the control circuit is used for subtracting the direct current level positioned at the front in the cable motion direction from the direct current level positioned at the rear in the cable motion direction to obtain an operation difference value; the control circuit prestores the maximum value of the operation difference value corresponding to the same cable; when the operation difference value is less than or equal to one third of the maximum value, judging that the wire core is not stripped; and when the operation difference value is greater than one third of the maximum value, judging that the wire core is stripped.
Further, the dc level is set to F; the reflection intensity of the infrared modulation signal is set as A; setting the conversion coefficient after cable reflection as K1; the infrared intensity in sunlight is set as B; the negative sensitivity impact value is set to K2; the dc level f=k1×a-k2×b.
Further, the wire core detection sensor assembly comprises an infrared transceiver group; the infrared transceiver group comprises two infrared transceiver pipes and one infrared receiving pipe; the infrared receiving tubes can simultaneously receive infrared modulation signals which are sent by the two infrared transmitting tubes in the same infrared receiving tube group and reflected back by the cable.
Preferably, the two infrared emission tubes are symmetrically arranged; the infrared receiving tube is positioned between the two infrared transmitting tubes.
Further, the rotating mechanism is connected with a cutter fixing block in a sliding way; the cutter fixing block is provided with a wire skin recovery pipe; the cutter is arranged on the cutter fixing block and positioned in the wire skin recovery pipe; the wire skin recovery pipe moves synchronously with the cutter, so that the wire skin rotary-cut by the cutter is conveniently led out, and winding interference is prevented.

The rotating mechanism 1 is connected with a cutter fixing block 21 in a sliding way; the rotating mechanism 1 is provided with a cutter motor 22 for driving the cutter fixing block 21 to move; the cutter fixing block 21 is provided with a wire skin recovery pipe 7; the cutter 2 is arranged on the cutter fixing block 21 and is positioned in the wire skin recovery pipe 7; the cutter motor 22 is used for enabling the cutter 2 to move to abut against the wire cores 5, and under the feedback action of the two wire core detection sensor assemblies 3, namely after the wire cores are judged to be stripped, the cutter motor 22 does not drive the cutter 2 to feed in the cable direction any more, so that the cutter 2 is prevented from cutting the wire cores.
The wire core detection sensor assembly 3 comprises a mounting block 33 arranged on the rotating mechanism and an infrared transceiver group arranged in the mounting block 33; the infrared transceiver group comprises an infrared receiving tube 34 arranged on the mounting block 33 and opposite to the cable, and two infrared transmitting tubes 35 symmetrically distributed on two sides of the infrared receiving tube 34 and arranged on the mounting block 33; the connection line between the two infrared emission tubes 35 is perpendicular to the cable; the emitting direction of the infrared emitting tube 35 is inclined to the cable direction; the infrared transmitting tube 35 is used for transmitting an infrared modulation signal to the cable; the infrared receiving tube 34 is used for converting infrared modulation signals reflected by the cable into direct current levels.
The control circuit 6 includes an operation module for performing a difference operation on the dc levels converted by the two infrared receiving tubes 34; the infrared receiving tube 34 converts an infrared modulation signal emitted by an infrared emitting tube reflected by the cable into a direct current level; the control circuit 6 is used for subtracting the direct current level positioned at the front in the cable motion direction from the direct current level positioned at the rear in the cable motion direction to obtain an operation difference value; the control circuit 6 prestores the maximum value of the operation difference value corresponding to the same cable; when the operation difference value is less than or equal to one third of the maximum value, judging that the wire core is not stripped; and when the operation difference value is greater than one third of the maximum value, judging that the wire core is stripped.
During the rotation of the cutter 2, the intensity of the sunlight irradiated on the infrared receiving tubes 34 changes periodically and reciprocally along with the rotation of the whole device, but the two infrared receiving tubes 34 are installed at the same angle and are close to each other, so that the same sunlight is always received. Subtracting the modulated signals received by the two infrared receiving pipes 34, wherein when the two wire core detection sensor assemblies 3 face the wire skin 4, the obtained operation result is equal to zero regardless of the intensity of sunlight; when the wire core is stripped, one of the wire core detecting sensor assemblies 3 faces the wire core 5, and the refractive index of the wire core 5 to infrared rays and the refractive index of the wire skin 4 to infrared rays are obviously different, so that the carrier signals received by the two infrared receiving pipes 34 are different, and the obtained operation results are obviously different from zero values. The design can completely avoid the influence of sunlight, and the peeling device can accurately judge whether to peel off the wire or not in the sunlight.
Specifically, the infrared transmitting tube 35 transmits an infrared modulation signal of 38KHz, and the received signal is to convert the intensity of 38KHz into a direct current level F; the reflection intensity of the infrared modulation signal is set as A; setting the conversion coefficient after cable reflection as K1; the infrared signal in the sunlight will affect the sensitivity of the infrared receiving tube 34, the stronger the sunlight, the lower the sensitivity, and the negative sensitivity effect value is set to K2; the infrared intensity in sunlight is set as B, and the final output level f=k1×a-k2×b of the receiving tube.
Illustrating:

the direct current level F output by the front wire core detection sensor component is marked as F2, and F2=k1 is Ap-K2 is B;
f1-f2=0;
When the wire core is peeled off:
The direct current level F output by the post-knife wire core detection sensor assembly is marked as F1, and F1=k1×ax-K2×B;
the direct current level F output by the front wire core detection sensor component is marked as F2, and F2=k1 is Ap-K2 is B;
f1-f2=k1×ax-k1×ap > 0; (Ax is greater than Ap because the core reflectivity is higher than the skin);
it is actually determined whether or not peeling is performed by using the results of F1-F2, and it becomes very reliable.
In practical applications, the reflectivity difference occurs between the wire skins 4 at the two ends of the cutter 2 due to the existence of objective external factors. The difference value of F1-F2 is in the range of 0-127, namely the maximum value is 127 (repeated experimental calculation in a relatively ideal laboratory range), and when the actual value of F1-F2 is less than or equal to one third of the maximum value, namely F1-F2 is less than or equal to 40, F1-F2=0 is judged, and the cable is not stripped; otherwise, when F1-F2 is more than 40, the cable is judged to be stripped.

The above embodiments are merely illustrative embodiments of the present invention, but the technical features of the present invention are not limited thereto, and any changes or modifications made by those skilled in the art within the scope of the present invention are included in the scope of the present invention.
