The embodiment of the invention also provides a wire stripping method applied to the wire stripping device of any one of the embodiments, which comprises the following steps:
s1, the lead 100 enters the lead input mechanism 1, and after the lead input mechanism 1 enables the end part of the lead 100 to exceed the blade of the cutter 222, the lead input mechanism 1 stops acting temporarily. The laser and photo-resistor correlation module may be disposed at a specific position in the wire stripping mechanism 2, when the wire 100 blocks the light emitted to the photo-resistor, the end of the wire 100 reaches the specific position, at this time, the input length of the wire 100 is calculated, and if the horizontal distance from the specific position to the blade of the cutter 222 is X, the input length of the wire 100 should be slightly greater than X, for example, one centimeter greater than X.
S2, enabling the two cutters 222 to form a potential difference, enabling the two cutters 222 to move oppositely until the lead 100 is completely cut off, enabling the cutter 222 to form a loop at the moment when the conductor of the lead 100 is just contacted with the cutter 222 in the process of cutting off the lead 100, and calculating the distance between the cutting edges of the two cutters 222 at the moment to obtain the diameter d of the conductor.
And S3, enabling the lead input mechanism 1 to continue to convey the lead 100 until the end of the lead 100 exceeds the cutting edge of the cutter 222 by a first preset length L1, wherein the first preset length L1 is equal to the length of one end of the lead 100 needing to be stripped.
And S4, moving the two cutters 222 oppositely until the distance between the cutting edges of the two cutters 222 is 1 mm larger than the diameter d, wherein the 1 mm allowance can prevent the cutter 222 from accidentally damaging the conductor in the wire 100, cutting the outer skin of the wire 100 by the cutter 222, then keeping the two cutters 222 away from each other, and resetting the cutter 222.
And S5, rotating the cutting assembly 22 by 90 degrees, and moving the two cutters 222 towards each other again until the distance between the cutting edges of the two cutters 222 is 1 mm larger than the diameter d, wherein after the step is completed, a section of the outer skin at one end of the lead 100 is basically cut off, and the section of the outer skin can be torn off only by small acting force.
S6, the lead input mechanism 1 is reversely operated, the lead 100 is drawn back by 1 cm, and the outer skin is peeled off by the cutter 222. In the previous step, the cutter 222 is kept at the original position after the cutting action, and is not reset, and the cutter 222 is matched with the lead input mechanism 1 to automatically pull the outer skin off. When only one end of the wire 100 needs to be stripped, the wire 100 can be withdrawn by the reverse action of the wire input mechanism 1, and if a target cable with a specific length needs to be cut, the other end of the target cable needs to be stripped, and the next step needs to be carried out.
S7, enabling the lead input mechanism 1 to continuously convey the lead 100 in the forward direction, enabling the conveying length to be a second preset length L2, enabling the lead 100 to enter the lead output mechanism 3, repeating the actions of the step S4 and the step S5, and enabling the cutter 222 to reset after the action of the step S5 is completed;
and S8, enabling the lead input mechanism 1 to forward convey the lead 100 again, wherein the conveying length is a third preset length L3, the third preset length L3 is equal to the length of the other end of the lead 100, which needs to be stripped, then enabling the cutter 222 to completely cut off the lead 100 to obtain a target cable, and resetting the cutter 222, wherein the length of the target cable is equal to the length of the target cable after 1 centimeter is subtracted from L2+ L3. In step S6, the wire 100 is pulled back 1 cm, so it needs to be subtracted by 1 cm, and from the above calculation, we can find that L2 is equal to the length of the target cable minus L3 plus 1 cm.
For example, when it is necessary to cut a target cable having a length of 100 cm and a peeled length of 5 cm, the transmission length of the wire 100 in step S7 is 100-5+1 96 cm, i.e., L2.
And S9, reversely actuating the lead wire output mechanism 3 until the target cable is drawn back to the third preset length L3, and moving the two cutting knives 222 towards each other until the distance between the cutting edges of the two cutting knives 222 is 1 mm larger than the diameter d, and then returning the cutting edges of the cutting knives 222 to the cut of the cut sheath in the step S7.
S10, the lead output mechanism 3 is enabled to move forwards, the target cable moves forwards by 1 cm, the cutter 222 peels off the outer skin and then resets, and the lead output mechanism 3 sends out the target cable.
The wire stripping method of the embodiment can not only strip one end of the wire 100, but also intercept a cable with a specific length according to actual needs, and automatically strip one end or two ends of the cable, and the wire input mechanism 1 and the wire output mechanism 3 are matched with the cutter 222, so that the cutter 222 can not only cut the outer skin, but also strip the outer skin, and the wire stripping method has high automation degree, and has high wire stripping efficiency and wire stripping precision.
