Description

Technical Field

[0001] The present invention relates to the technical field of cables, and in particular, to a method and device for peeling the skin of a cable. Background Art

[0002] During the use of a cable, in order to achieve a crimp connection with a terminal and thus achieve a fast and reliable electrical connection with other functional components, it is necessary to strip the insulating skins at both ends of the cable to expose the conductors. In the prior art, for the stripping of the insulating skin of a cable, usually a circular break is first cut in the insulating skin at a set position by a specific operation, and then the part of the insulating skin to be stripped is peeled off from the cable.

[0003] However, currently, when forming the circular break, the cutting is mostly carried out by rotating a cutter. Since it is difficult to ensure the uniformity of the thickness of the insulating skin of the cable in the circumferential direction, when the cutting depth is relatively shallow, the insulating skin is tightly combined with the cable, and the subsequent peeling operation will be very difficult; while when the cutting depth is relatively large, although the insulating skin can be peeled off relatively easily, due to the uneven thickness of the insulating skin, the cutter is very likely to cut the conductor at the thinner part, affecting the normal use and electrical performance of the cable. The key problem of the prior art is that in the process of peeling the insulating skin of the cable by rotating the cutter to form a circular break, it is difficult to balance the cutting depth and it is impossible to smoothly peel the insulating skin while avoiding cutting the conductor.

[0046] During the processing of the cable, in order to achieve the electrical connection between the core wire 42 and other components, it is necessary to strip the insulating sleeve 41 wrapped outside the core wire 42. In the prior art, a tool is usually used to cut a circular incision on the insulating sleeve 41 for subsequent stripping of the insulating sleeve 41. However, this method has obvious defects: if the cutting depth of the circular fracture is relatively shallow, the bonding force between the insulating sleeve 41 and the core wire 42 is relatively large, resulting in difficulty in stripping the insulating sleeve 41 from the core wire 42; if the cutting depth is relatively large, since it is difficult to ensure the thickness uniformity of the insulating sleeve 41 in the circumferential direction, at the thinner part of the insulating sleeve 41, the tool is very likely to cut the core wire 42, thus damaging the structure of the cable unit 04 and affecting its normal use and electrical performance. Therefore, how to smoothly strip the insulating sleeve 41 on the premise of avoiding cutting the core wire 42 has become an urgent problem to be solved in the processing technology of the insulating sleeve 41 of the cable unit 04. In this embodiment, a cable peeling method is provided. The cable peeling method includes steps S10 to step S20, as Figure 1 shown, and the details of each step are as follows:

[0047] Step S10, first obtain the thickness of the insulating sleeve 41 of the cable unit 04. As Figure 4 shown, the cable unit 04 may include an insulating sleeve 41 and a core wire 42, and the insulating sleeve 41 may be wrapped outside the core wire 42. By obtaining the thickness of the insulating sleeve 41, it can provide a data reference for the subsequent setting of the cutting depth of the insulating sleeve 41, facilitating more accurate control of the cutting operation.

[0048] Step S20, step S20 may include steps S21 to S24, and the details of each step are as follows:

[0049] Step S21, control the first traction unit 21 to drive the cable unit 04 to move in the first direction until the first end of the cable unit 04 sequentially passes through the first cutting unit 22 and the second cutting unit 23 and reaches the first preset position. Among them, in the state where the first end is located at the first preset position, the length of the first cutting unit 22 from the first end is the first length, and the length of the second cutting unit 23 from the first end is the second length. The first length may be greater than the second length, that is, the second cutting unit 23 is located between the first cutting unit 22 and the first end. This operation positions the cable unit 04 and at the same time determines the part that needs to be peeled, that is, the part between the first cutting unit 22 and the first end, providing an accurate position basis for subsequent operations and ensuring the accuracy of the cutting position.

[0050] Step S22, based on the first end of the cable unit 04 being located at the first preset position, controls the first cutting unit 22 to cut a first incision on the insulating sleeve 41, and controls the second cutting unit 23 to cut a second incision on the insulating sleeve 41. The first incision can be an annular incision surrounding the axis of the cable unit 04, the depth of the first incision is the first cutting depth, and the depth of the second incision is the second cutting depth. The first cutting depth can be less than the thickness of the insulating sleeve 41, and the second cutting depth can be less than the thickness of the insulating sleeve 41 to avoid cutting the core wire 42 and damaging the cable unit 04. By setting two cutting units to cut separately, the insulation to be stripped is divided into two sections that are not completely separated, thereby dividing the stronger force required for stripping the insulation layer into two weaker forces, and the two weaker forces are borne by the first cutting unit and the second cutting unit respectively, thereby reducing the difficulty of stripping the insulation. In addition, the first incision is an annular incision, and the cable is easier to disconnect from the first incision, thereby ensuring the accuracy of the position of the cable peeling.

[0051] In another embodiment, the cable is unwound by the feeding unit and transferred to the first traction unit 21. The first cutting unit 22 can include a first upper blade 2221 and a first lower blade 2222, and the second cutting unit 23 can include a second upper blade 2321 and a second lower blade 2322. The cable unit 04 can be located between the first upper blade 2221 and the first lower blade 2222. The first upper blade 2221 and the first lower blade 2222 can simultaneously cut into the insulating sleeve 41 and rotate. The second upper blade 2321 and the second lower blade 2322 can cut into the insulating sleeve 41 simultaneously or separately.

[0052] In step S23, based on the first cutting unit 22 having cut to the first cutting depth and the second cutting unit 23 having cut to the second cutting depth, the first cutting unit 22 is controlled to move toward the second cutting unit 23. By moving the first cutting unit 22 before stripping, the gap between the first cutting unit 22 and the second cutting unit 23 is reduced, exerting a pressing force toward the first end of the cable on the second cutting unit 23 near the first end of the cable. This balances the reverse thrust exerted on the second cutting unit 23 during insulation stripping, minimizing fatigue deformation of the blade of the second cutting unit 23 from prolonged operation.

[0053] Step S24: Based on the distance between the first cutting unit 22 and the second cutting unit 23 reaching the first preset distance, control the first cutting unit 22 to stop moving, and control the first traction unit 21 to drive the cable unit 04 to move a second preset distance in the second direction, and the peeling of the first end is completed. Here, the second direction is opposite to the first direction. By moving the first cutting unit 22 in the first direction to reduce the distance between the first cutting unit 22 and the second cutting unit 23, and then applying a force in the second direction to the cable unit 04 with a cut, the insulating skin stuck under the cutting edges of the first cutting unit 22 and the second cutting unit 23 can be smoothly peeled off under the action of the blade resistance, completing the peeling operation of the first end of the cable.

[0054] In this embodiment, the second cut can be an annular cut around the axis of the cable unit 04, or the second cut can be an arc-shaped cut around the axis of the cable unit 04. When the second cut is an annular cut, when peeling the insulating skin, more of the force when the insulating skin between the second cutting unit 23 and the first end of the cable detaches acts on the second cutting unit 23, reducing the force on the first cutting unit 22 to protect the cutting edge of the first cutting unit 22; when the second cut is an arc-shaped cut, when peeling the insulating skin, part of the force when the insulating skin between the second cutting unit 23 and the first end of the cable detaches acts on the second cutting unit 23, and part acts on the first cutting unit 22 through the insulating sleeve 41 without a cutting edge, reducing the force on the second cutting unit 23 to protect the cutting edge of the second cutting unit 23.

[0055] In this embodiment, the first cutting depth can be greater than the second cutting depth. The first cutting unit 22 cuts deeper, which can ensure that the insulating skin is completely peeled off starting from the first cutting unit 22; the second cutting unit 23 cuts shallower, which can not only bear part of the force during peeling but also avoid damaging the core wire 42.

[0056] In this embodiment, the difference between the first length and the second length can be less than the second length, so that the insulating skin between the second cutting unit 23 and the first end of the cable is not too much, avoiding excessive force on the second cutting unit 23 during peeling and resulting in fatigue deformation.

[0057] In this embodiment, the difference between the first length and the second length can be greater than half of the second length, so that the insulating skin on the side of the second cutting unit 23 close to the first end of the cable is not too little, enabling the second cutting unit 23 during peeling, and avoiding the situation where the second cutting unit 23 cannot share enough force for the first cutting unit 22 during peeling, resulting in fatigue deformation of the first cutting unit 22.

[0058] In this embodiment, the cable peeling method can further include steps S30 to S50, and the details of each step are as follows:

[0059] Step S30: Based on the completion of the peeling of the first end of the cable unit 04, control the first cutting unit 22 and the second cutting unit 23 to reset. When the first cutting unit 22 and the second cutting unit 23 are in the reset state, the distance between the first cutting unit 22 and the second cutting unit 23 is the difference between the first length and the second length, and the first cutting unit 22 and the second cutting unit 23 are separated from the insulating sleeve 41.

[0060] Step S40: Based on the completion of the reset of the first cutting unit 22 and the second cutting unit 23, control the first traction unit 21 to drive the cable unit 04 to move in the first direction until the third cutting unit 25 is located at the preset cutting position of the cable unit 04, and the first end enters the second traction unit 26. Among them, the length of the preset cutting position from the first end is the length of the finished cable.

[0061] Step S50: Based on the third cutting unit 25 being located at the preset cutting position, control the third cutting unit 25 to cut the cable unit 04. When the cable unit 04 is cut, the cable unit 04 can be cut into a cable semi-finished product and the remaining cable unit 04. A cut is formed between the second end of the cable semi-finished product and the first end of the remaining cable unit 04 by the third cutting unit 25. Through the above steps, after the peeling of one end of the cable is completed, the cable is cut at a fixed length to form a cable semi-finished product. At this time, the first end of the cable semi-finished product has been peeled, and the second end has not been peeled. In another embodiment, the third cutting unit 25 may include a third upper knife 2521 and a third lower knife 2522, and the third upper knife 2521 and the third lower knife 2522 can simultaneously cut into the cable unit 04 until the third upper knife 2521 and the third lower knife 2522 abut, thereby cutting the cable unit 04.

[0062] In this embodiment, the cable peeling method may further include step S60, and step S60 may include steps S61 to S64. The details of each step are as follows:

[0063] Step S61: Based on the completion of the cutting of the cable unit 04, control the first traction unit 21 to drive the cable residue to move in the second direction, and control the second traction unit 26 to drive the cable semi-finished product to move in the second direction until the second end of the cable semi-finished product passes through the second cutting unit 23 and the first cutting unit 22 in sequence and reaches the second preset position. When the second end of the cable semi-finished product is in the second preset position, the distance between the first cutting unit 22 and the second end of the cable semi-finished product is the second length, and the distance between the second cutting unit 23 and the second end of the cable semi-finished product is the first length. Among them, the first length is the length that needs to be peeled at both ends of the finished cable.

[0064] In step S62, based on the second end of the semi-finished cable being located at the second preset position, the first cutting unit 22 is controlled to cut a third incision into the insulating sleeve 41 of the semi-finished cable, and the second cutting unit 23 is controlled to cut a fourth incision into the insulating sleeve 41 of the semi-finished cable. The fourth incision is an annular incision circumferentially around the axis of the semi-finished cable. The depth of the fourth incision is the first cutting depth, and the depth of the third incision is the second cutting depth. The first cutting depth is less than the thickness of the insulating sleeve 41, and the second cutting depth can be less than the first cutting depth. This ensures that the insulating sleeve 41 can be separated from the fourth incision while avoiding cutting the core wire 42 and damaging the cable unit 04.

[0065] In step S63, the first cutting unit 22 cuts to the second cutting depth, and the second cutting unit 23 cuts to the first cutting depth. The second cutting unit 23 is controlled to move toward the first cutting unit 22, thereby reducing the distance between the first cutting unit 22 and the second cutting unit 23, and applying an extrusion force toward the second end of the cable to the first cutting unit 22 near the second end of the cable. This extrusion force can balance the reverse thrust from the insulation layer that the first cutting unit 22 will receive when stripping the insulation layer, so as to avoid fatigue deformation of the blade of the first cutting unit 22 as much as possible.

[0066] In step S64, upon the distance between first cutting unit 22 and second cutting unit 23 reaching the first predetermined distance, second cutting unit 23 is controlled to stop moving, and second pulling unit 26 is controlled to move the semi-finished cable in the first direction by the second predetermined distance, thereby completing the stripping of the second end of the semi-finished cable. By moving second cutting unit 23 in the second direction to reduce the distance between first cutting unit 22 and second cutting unit 23, a force in the first direction is applied to the cut first end of cable unit 04. This allows the insulation trapped between the blades of first cutting unit 22 and second cutting unit 23 to be smoothly stripped away due to the resistance of the blades, thus completing the stripping operation of the second end of the cable.

[0067] In this embodiment, the third incision may be an annular incision surrounding the axis of the cable unit 04, or the third incision may be an arcuate incision surrounding the axis of the cable unit 04. When the third incision is an annular incision, the force applied when stripping the insulation between the first cutting unit 22 and the second end of the semi-finished cable can be applied more to the first cutting unit 22, reducing the force applied to the second cutting unit 23 and thus protecting the blade of the second cutting unit 23. When the third incision is an arcuate incision, the force applied when stripping the insulation between the first cutting unit 22 and the second end of the semi-finished cable can be applied partially to the first cutting unit 22 and partially to the second cutting unit 23, reducing the force applied to the first cutting unit 22 and thus protecting the blade of the first cutting unit 22.

[0068] In this embodiment, the cable peeling method may further include steps S70 to S80, and the details of each step are as follows:

[0069] In step S70, based on the completion of the peeling of the second end of the semi-finished cable, the second traction unit 26 is controlled to drive the semi-finished cable to move in the first direction until the blanking is completed, and the remaining cable unit 04 is controlled to move in the first direction.

[0070] In step S80, steps S20 to S70 can be repeated until the length of the remaining cable unit 04 is less than the preset length. Through the above steps, automatic blanking after peeling can be achieved and the peeling steps can be repeated until all the cable units 04 are peeled off.

[0071] In this embodiment, a cable peeling device is provided. The cable peeling device is applied to any of the cable peeling methods in the above embodiments, such as Figure 2 and Figure 3 As shown, the cable peeling device may include a peeling assembly 02. The peeling assembly 02 may include a first traction unit 21, a first cutting unit 22, a second cutting unit 23, and an adjusting unit 24 arranged in sequence in the first direction.

[0072] The first traction unit 21 can be used to drive the cable unit 04 to move in the first direction or the second direction. Among them, the second direction is opposite to the first direction. The adjusting unit 24 can adjust the distance between the first cutting unit 22 and the second cutting unit 23. The first cutting unit 22 and the second cutting unit 23 can be used to cut the insulating sleeve 41.

[0073] The first cutting unit 22 may include a first tool rest 221, a first cutting tool 222, and a first driving part. The first cutting tool 222 is movably connected to the first tool rest 221, and the first driving part can drive the first cutting tool 222 to move in the first cutting direction. Among them, the first cutting direction is perpendicular to the first direction. The first driving part can also drive the first cutting tool 222 to rotate. When the cable unit 04 passes through the first cutting unit 22, the axis around which the first cutting tool 222 rotates is the axis of the cable unit 04. The first cutting tool 222 can cut the cable unit 04 in the first cutting direction and rotate without lifting the tool, so as to cut an annular incision around the axis of the cable unit 04 on the cable unit 04.

[0074] The second cutting unit 23 may include a second tool rest 231, a second cutting tool 232, and a second driving part. The second cutting tool 232 is movably connected to the second tool rest 231. The second driving part may drive the second cutting tool 232 to move in the first cutting direction, so that the second cutting tool 232 can cut a notch in the cable unit 04 in the first cutting direction.

Then, both the first cutting unit 22 and the second cutting unit 23 cut the cable unit 04 at the corresponding positions to cut out the cutting edges. When the blades of the first cutting unit 22 and the second cutting unit 23 are still stuck on the cable unit 04, the first cutting unit 22 can be driven by the adjusting unit 24 to move a preset distance in the direction close to the second cutting unit 23. Finally, the cable unit 04 is driven by the first traction unit 21 to move in the direction of the second cutting unit 23 close to the first cutting unit 22, and the skinning of the first end of the cable unit 04 can be realized.

[0076] In this embodiment, as Figure 3 shown, the stripping assembly 02 may further include a third cutting unit 25 and a second traction unit 26. The second cutting unit 23, the third cutting unit 25, and the second traction unit 26 are arranged in sequence along the first direction. The third cutting unit 25 can be used to cut the cable unit 04. The second traction unit 26 can be used to drive the cable unit 04 or the cable semi-finished product to move in the first direction or the second direction. The third cutting unit 25 may include a third tool rest 251, a third cutting tool 252, and a third driving part. The third cutting tool 252 is movably connected to the third tool rest 251. The third driving part may drive the third cutting tool 252 to move in the first cutting direction, so that the third cutting can cut the cable assembly in the first cutting direction. By adding the third cutting unit 25, after skinning the first end of the cable unit 04, the cable unit 04 can be cut at a preset length to form a cable semi-finished product. Then, the cable is driven by the third driving part to pass through the second cutting unit 23 and the first cutting unit 22 in sequence from the second direction, and after skinning the second end of the cable semi-finished product, it is discharged.

[0077] Those of ordinary skill in the art can understand that the above embodiments are specific cases for implementing the present disclosure. In actual applications, various changes can be made to it in form and details without departing from the scope of the present disclosure.
