Abstract
Description
Technical Field
[0001] This invention relates to the field of wire harness processing technology, specifically to an integrated cutting and stripping device and method for automotive wire harness processing. Background Technology
[0002] Automotive wiring harnesses are the nerve and blood vessel network connecting various electrical and electronic modules in a vehicle's circuitry. They consist of wires, terminals, connectors, sheaths, and various wrapping materials, and perform crucial functions in power distribution and signal transmission. During production, the entire reel of cable is first cut to the designed length at equal intervals, and both ends are precisely stripped to expose the core wires. Then, a terminal is crimped at one end to facilitate insertion into the connector housing, achieving a reliable electrical connection with the corresponding module.
[0003] Existing wire stripping methods mainly rely on two symmetrical toothed cutters. By moving one cutter towards the other, at least four circumferentially distributed cuts are pressed into the cable sheath, and then the sheath is pulled off from the end. In this process, if the sheath material is tough, it is often difficult to pull off neatly, affecting the stripping efficiency. Or, significant elongation deformation may occur during the pulling off process, resulting in uneven cut ends or even residual burrs. This directly affects the crimping depth and sheath shape of subsequent terminals, reducing the electrical and mechanical reliability of the crimping. Summary of the Invention
[0004] This invention provides an integrated cutting and stripping device for automotive wiring harness processing. By setting up two auxiliary rings and one main ring, the outer sheath can be removed more efficiently and with less effort. The cut of the cable will also be neater, preventing the cut of the cable from being flat, which will result in better crimping of the terminal. This solves the problem of uneven stripped end face that affects the shape of the terminal mentioned in the background art.
[0005] This invention provides the following technical solution: An integrated cutting and stripping device for automotive wiring harness processing includes a frame and a protective cover with a grooved bottom, fixedly connected to the frame. The protective cover has circular holes on both sides, and a main ring and two auxiliary rings are rotatably mounted inside the cover, with the two auxiliary rings located on opposite sides of the main ring. Three sets of cutting tools are respectively installed inside the main ring and the auxiliary rings. The cutting depth of the cutting tools on the main ring is greater than that of the cutting tools on the auxiliary rings. The protective cover has a drive unit for rotating the main ring and the auxiliary rings.
[0006] As a preferred embodiment of the present invention, the driving unit includes two driving gears rotatably mounted inside the protective cover. The two driving gears are respectively located on both sides of the main ring. Driven gears are fixedly mounted on both the main ring and the secondary ring. The driving gears mesh with the driven gears. A drive motor for driving one of the driving gears to rotate is fixedly mounted on the protective cover.
[0007] As a preferred embodiment of the present invention, the inner walls of the main ring and the secondary ring are provided with two symmetrically arranged sliding holes, and a sliding column is slidably installed in each of the two sliding holes. The cutting tool is fixedly installed at one end of the sliding column, and a limit plate is installed at the other end of the sliding column. The outer walls of the main ring and the secondary ring are provided with annular grooves, and a pushing part is provided in the annular grooves to push the sliding column to slide along the sliding holes.
[0008] As a preferred embodiment of the present invention, the pushing part includes two sets of arc-shaped plates disposed in an annular groove. The two arc-shaped plates are brought close to each other and combined to form a continuous annular plate. A reset spring is installed between the limiting plate and the inner wall of the annular groove. A first telescopic device for pushing the arc-shaped plates to move is fixedly installed on the inner wall of the protective cover.
[0009] As a preferred embodiment of the present invention, the cutting head of the tool is provided with an inclined cutting edge, the cutting edges on the main ring and the secondary ring are inclined in opposite directions, and the rotation directions of the main ring and the secondary ring are opposite.
[0010] As a preferred embodiment of the present invention, a roller is rotatably mounted on the limiting plate, and protrusions with equal spacing are fixedly arranged on the inner wall of the arc plate. When the two arc plates approach each other, the roller presses against the inner wall of the arc plate. When the main ring and the secondary ring continue to rotate, the roller will roll along the inner wall of the arc plate and press against the protrusions in sequence.
[0011] As a preferred embodiment of the present invention, a crossbar is fixedly connected to both sides of the sliding column of the main ring, and a device block is connected to the end of the crossbar near the side wall of the secondary ring. The device block is provided with an inclined surface and anti-slip texture. The inclination direction of the inclined surface is opposite to the inclination direction of the cutting edge of the secondary ring.
[0012] As a preferred embodiment of the present invention, a first slide rail is fixedly installed on the frame, a first slide table is slidably installed on the first slide rail, and a gripper is fixedly installed on the first slide table.
[0013] As a preferred embodiment of the present invention, a bracket is mounted on the frame, a straightener is mounted on the bracket, a second slide rail perpendicular to the first slide rail is mounted on the frame, a second slide table is slidably mounted on the second slide rail, a third slide rail parallel to the first slide rail is mounted on the second slide table, a support plate is mounted on the third slide rail, a tubular spring is fixedly connected to the support plate, the axes of the circular holes of the tubular spring are collinear, and a terminal crimping device located at the end of the second slide rail is mounted on the frame.
[0014] A method for cutting and stripping automotive wiring harnesses includes the following steps: S1. Repeatedly bend the cable to eliminate internal stress; S2. The cable is cut and the outer sheath is cut using three sets of tools. The cutting path is a circular ring around the cable axis. S3. During the cutting process, the tool is moved back and forth along the radial direction of the cable. S4. Pull out the cut cable, and remove the outer sheath at the same time; S5. Move the cable to the terminal crimping device to complete the terminal crimping.
[0015] Compared with the prior art, the present invention provides an integrated cutting and stripping device for automotive wire harness processing, which has the following advantages: 1. In this integrated cutting and stripping equipment for automotive wiring harness processing, the main ring and the auxiliary ring rotate synchronously through the cooperation of a motor, a drive gear, and a driven gear. This, in turn, drives the cutter to rotate synchronously. The cutter on the main ring not only cuts the outer sheath but also the wire core, while the cutter on the auxiliary ring only cuts the outer sheath of the cable. Both cuts are circular, which allows the outer sheath to be removed more easily and efficiently during subsequent stripping. The cut of the cable is also neater, preventing the cut from being flat and resulting in better crimping of the terminals.
[0016] 2. In this integrated cutting and stripping equipment for automotive wiring harness processing, when the cutter revolves around the cable, the inclined cutting edge can more easily slide along the outer wall of the cable. Since the main ring and the secondary ring rotate in opposite directions, the two sets of cutters will cause the cable sheath to twist in a twisted shape. The twisting will cause the sheath to gradually separate from the wire core, so as to facilitate the subsequent stripping work. At the same time, after the sheath can no longer be twisted, the sheath is in a taut state, which makes it easier for the cutter to complete the cutting of the sheath.
[0017] 3. In this integrated cutting and stripping equipment for automotive wire harness processing, rollers press against the inner wall of an arc-shaped plate, and the rollers intermittently press against the cutting tool. The cutting tool intermittently presses against the cable axis. The maximum cutting radius of the cutting tool on the main ring is the wire core radius or two-thirds of the wire core radius, and the maximum cutting depth of the cutting tool on the secondary ring is the thickness of the cable sheath. Instead of using a fixed force and cutting depth to cut the sheath and wire core, the rotating cutting tool prevents the wire core from rotating synchronously, thus ensuring the cutting efficiency of the sheath and wire core.
[0018] 4. In this integrated cutting and stripping equipment for automotive wiring harness processing, the crossbar drives the device block to move synchronously. The inclined surface on the device block presses against the outer wall of the cable and is close to the stripping cut. When the main ring and the auxiliary ring rotate, since they rotate in opposite directions, the inclined surface will be driven to rub along the outer wall of the cable, making the outer sheath more efficiently separated and loosened from the wire core. The subsequent stripping efficiency will be higher, and the outer sheath will not easily remain on the surface of the wire core.
[0019] The parts of this device not covered herein are the same as or can be implemented using existing technologies. By setting up two secondary rings and one main ring, this invention can make the outer sheath more easily and efficiently removed, and the cable cut will be neater, preventing the cable cut from being flat, thus improving the effect of subsequent crimping of terminals.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] Reference Figures 1-8 As shown, an integrated cutting and stripping device for automotive wire harness processing includes a frame 1 and a protective cover 2 with a grooved bottom, fixedly connected to the frame 1. The protective cover 2 has circular holes 3 on both sides, serving as an inlet and outlet hole respectively. A main ring 4 and two auxiliary rings 5 are rotatably mounted inside the protective cover 2, with the two auxiliary rings 5 located on either side of the main ring 4. Three sets of cutters 6 are respectively installed within the main ring 4 and the auxiliary rings 5, with each set containing two symmetrical cutters 6. The cutting depth of the cutter 6 on the main ring 4 is greater than the cutting depth of the cutter 6 on the auxiliary rings 5. The cutter 6 on the main ring 4 is used to cut the entire wire harness, and the cutter 6 on the secondary ring 5 is used to cut the outer sheath of the wire harness. The protective cover 2 is provided with a drive unit that drives the main ring 4 and the secondary ring 5 to rotate, so that the cutter 6 revolves along the axis of the wire harness. The drive unit includes two drive gears 18 rotatably installed inside the protective cover 2. The two drive gears 18 are located on both sides of the main ring 4. Driven gears 19 are fixedly installed on both the main ring 4 and the secondary ring 5. The drive gears 18 and the driven gears 19 are meshed and connected. A drive motor 17 that drives one of the drive gears 18 to rotate is fixedly installed on the protective cover 2.
[0025] In use, the cable is passed through the two circular holes 3 in sequence. When the preset length is reached, the drive motor 17 is started. The drive motor 17 will drive one of the driving gears 18 to rotate. Then, under the action of the driven gear 19, all the driving gears 18 and driven gears 19 will rotate. This will drive the main ring 4 and the secondary ring 5 to rotate synchronously, which in turn will drive the cutter 6 to rotate synchronously. The cutter 6 on the main ring 4 not only cuts the outer sheath but also cuts the wire core, while the cutter 6 on the secondary ring 5 only cuts the outer sheath of the cable. Both cuts are circular, so the outer sheath can be removed more easily and efficiently during subsequent stripping. The cut of the cable will also be neater, preventing the cut of the cable from being flat, and making the subsequent crimping terminal effect better.
[0026] Of course, in other embodiments, the inner walls of the main ring 4 and the secondary ring 5 are provided with two symmetrically arranged sliding holes 8, and a sliding column 9 is slidably installed in each of the two sliding holes 8. The cutter 6 is fixedly installed at one end of the sliding column 9, and a limiting plate 10 is installed at the other end of the sliding column 9. The outer walls of the main ring 4 and the secondary ring 5 are provided with annular grooves 12. The annular grooves 12 are provided with a pushing part that pushes the sliding column 9 to slide along the sliding hole 8. The pushing part includes two sets of arc plates 11 provided in the annular grooves 12. The two arc plates 11 are combined to form a continuous annular plate after they approach each other. A return spring 13 is installed between the limiting plate 10 and the inner wall of the annular groove 12. The inner wall of the protective cover 2 is fixedly installed with a first telescopic device 16 that pushes the arc plate 11 to translate. The first telescopic device 16 is a cylinder or an electric telescopic rod.
[0027] After the cable length is determined, the first telescopic device 16 drives the arc plate 11 to move towards the cable. The arc plate 11 will press against the limiting plate 10, and the limiting plate 10 will compress the return spring 13. At the same time, it will drive the sliding column 9 and the cutter 6 to move synchronously. The cutter 6 will be pressed into the cable, which will facilitate the subsequent cutting and stripping of the cable. Before this, the cutter 6 will not contact the outer wall of the cable, which will facilitate the cable to pass through the main ring 4 and the secondary ring 5.
[0028] Reference Figure 8 As shown, the cutting head of the tool 6 is provided with an inclined cutting edge 7. The cutting edges 7 on the main ring 4 and the secondary ring 5 are inclined in opposite directions, and the rotation directions of the main ring 4 and the secondary ring 5 are opposite.
[0029] When the cutter 6 revolves around the cable, the inclined cutting edge 7 can more easily slide along the outer wall of the cable. Since the main ring 4 and the secondary ring 5 rotate in opposite directions, the two sets of cutters 6 will cause the cable sheath to twist in a twisted shape, rather than rotating the entire cable sheath on the outer wall of the wire core. The twisting will cause the sheath to gradually separate from the wire core, so as to facilitate the subsequent stripping work. At the same time, after the sheath can no longer be twisted, the sheath is in a taut state, which makes it easier for the cutter 6 to complete the cutting of the sheath. For this purpose, the cutter 6 needs to rotate at least two revolutions on the outer wall of the cable.
[0030] Reference Figure 8 As shown, a roller 14 is rotatably mounted on the limiting plate 10, and protrusions 15 are fixedly arranged at equal intervals on the inner wall of the arc plate 11. When the two arc plates 11 approach each other, the roller 14 presses against the inner wall of the arc plate 11. When the main ring 4 and the secondary ring 5 continue to rotate, the roller 14 will roll along the inner wall of the arc plate 11 and press against multiple protrusions 15 in sequence.
[0031] When the arc plate 11 moves toward the cable, the roller 14 presses against the inner wall of the arc plate 11. At this time, the cutting depth of the cutter 6 on the secondary ring 5 is half or one-third of the outer sheath thickness, and the cutting depth of the cutter 6 on the main ring 4 is penetrating to the surface of the wire core, one-third of the wire core radius, or half of the wire core. After the main ring 4 and the secondary ring 5 rotate, multiple protrusions 15 will press the roller 14 in sequence, causing the roller 14 to intermittently press the cutter 6. The cutter 6 will intermittently press toward the cable axis. The maximum cutting range of the cutter 6 on the main ring 4 is the wire core radius or two-thirds of the wire core radius, and the maximum cutting depth of the cutter 6 on the secondary ring 5 is the cable sheath thickness. Instead of using a fixed force and cutting depth to cut the outer sheath and wire core, the rotating cutter 6 prevents the wire core from rotating synchronously, thus ensuring the cutting efficiency of the outer sheath and wire core.
[0032] In practice, it was found that the initial state of the cutter 6 on the main ring 4 is only on the surface of the wire core. It will only cut the wire core after subsequent reciprocating movement, which is the preferred cutting state of the cutter 6.
[0033] Reference Figure 7 As shown, both sides of the sliding column 9 of the main ring 4 are fixedly connected to a crossbar 24. The end of the crossbar 24 is connected to a device block 20 near the side wall of the secondary ring 5. The device block 20 is provided with an inclined surface 21, and the inclined surface 21 is provided with anti-slip texture. The anti-slip texture is shown in the figure but not marked. The inclination direction of the inclined surface 21 is opposite to the inclination direction of the cutting edge 7 of the secondary ring 5.
[0034] After the cutter 6 approaches the cable, it will also drive the device block 20 to move synchronously through the crossbar 24. The inclined surface 21 on the device block 20 will press on the outer wall of the cable and be close to the stripping cut. When the main ring 4 and the secondary ring 5 rotate, since the two rotate in opposite directions, the inclined surface 21 will be driven to rub along the outer wall of the cable, so that the outer sheath can be separated from the wire core more efficiently. The subsequent stripping efficiency will be higher, and the outer sheath will not easily remain on the surface of the wire core.
[0035] In addition, a crossbeam 22 is fixedly connected to the main ring 4, and a guide rod 23 is slidably installed on the crossbeam 22. The device block 20 is fixedly connected to the guide rod 23, so the guide rod 23 can guide the moving device block 20.
[0036] Reference Figure 3 As shown, a first slide rail 25 is fixedly installed on the frame 1, a first slide table 26 is slidably installed on the first slide rail 25, and a clamp 27 is fixedly installed on the first slide table 26.
[0037] After the cutting work is completed, the first slide rail 25 drives the first slide table 26 to move horizontally until the clamp 27 can hold the cable. Then, the end of the cable is dragged, and the blade 6 and the inclined surface 21 that have not completed the retraction can scrape off the outer sheath, thereby completing the stripping work of the cable end. Of course, the clamp 27 can also clamp the outer sheath of another cable being cut and pull it away from the end of the cable, so that the other end of the cable can be stripped.
[0038] Reference Figures 1-4 As shown, a bracket 28 is installed on the frame 1, and a straightener 29 is installed on the bracket 28. The straightener 29 is mainly composed of guide wheels arranged in an alternating manner. When the cable passes through, it will move in a wavy line path. A second slide rail 40 perpendicular to the first slide rail 25 is installed on the frame 1. A second slide table 39 is slidably installed on the second slide rail 40. A third slide rail 42 parallel to the first slide rail 25 is installed on the second slide table 39. A support plate 30 is installed on the third slide rail 42. A tubular spring 31 is fixedly connected to the support plate 30. The axis of the circular hole 3 of the tubular spring 31 is collinear with the axis of the circular hole 3. A terminal crimping device 41 located at the end of the second slide rail 40 is installed on the frame 1. The terminal crimping device 41 is mainly used to realize the automatic installation of wire harness terminals.
[0039] During use, the cable needs to pass through the straightener 29 and the tubular spring 31. The straightener 29 is used to eliminate the internal stress in the cable. The support plate 30 is moved away from the protective cover 2 by the third slide rail 42 until the end of the cable is pulled out from the round hole 3. At this time, the other cutter 6 and the inclined surface 21 will peel off the outer sheath of the current cable end. Then, the second slide table 39 is moved towards the terminal crimping device 41 by the second slide rail 40, which will drive the current cable to move synchronously. When the stripped cable end moves to the terminal crimping device 41, the terminal installation work of one end can be realized. During the movement of the second slide table 39, the tubular spring 31 can bend and twist with the cable to prevent the local part of the cable from being hard bent.
[0040] Reference Figure 5 and Figure 6 As shown, a base plate 33 is connected to the support plate 30, a support column 35 is fixedly connected to the base plate 33, a top plate 32 is slidably installed on the support column 35, a mounting plate 36 is fixedly connected to the top of the support column 35, a tension spring 37 is installed between the top plate 32 and the mounting plate 36, an arc groove 38 is opened on the opposite surfaces of the top plate 32 and the base plate 33, the axis of the arc groove 38 is collinear with the axis of the circular hole 3, and an electromagnet 34 is installed on the opposite surfaces of the top plate 32 and the base plate 33.
[0041] During use, the cable needs to pass through the circular channel formed by the two arc grooves 38. Before the cable needs to be moved to the terminal crimping device 41, the two electromagnets 34 are energized. The top plate 32 will be attracted to the bottom plate 33 under the magnetic force of the electromagnets 34, and the two arc grooves 38 will clamp the cable. This facilitates the movement of the cable and the stripping of the cable. When the operation is over, the electromagnets 34 are de-energized, the tension spring 37 will elastically return to its original position, thereby pulling the top plate 32 towards the mounting plate 36, and the arc grooves 38 will no longer clamp the cable.
[0042] Reference Figures 1-8 A method for cutting and stripping automotive wiring harnesses includes the following steps: S1. Repeatedly bend the cable to eliminate internal stress; S2. The cable is cut and the outer sheath is cut using three sets of cutters 6. The cutting path is a circular ring around the cable axis. S3. During the cutting process of the tool 6, the tool 6 is moved back and forth along the radial direction of the cable; S4. Pull out the cut cable, and remove the outer sheath at the same time; S5. Move the cable to the terminal crimping device 41 to complete the terminal crimping.
[0043] In this invention, during use, the cable needs to pass through the straightener 29 and the tubular spring 31. The straightener 29 is used to eliminate the internal stress in the cable. Then, the cable passes through two circular holes 3 in sequence. When the preset length is reached, the drive motor 17 is started. The drive motor 17 will drive one of the drive gears 18 to rotate. Then, under the action of the driven gear 19, all the drive gears 18 and driven gears 19 will rotate. This will drive the main ring 4 and the secondary ring 5 to rotate synchronously, which will in turn drive the cutter 6 to rotate synchronously. The cutter 6 on the main ring 4 not only cuts the outer sheath but also cuts the wire core, while the cutter 6 on the secondary ring 5 only cuts the outer sheath of the cable. Both cuts are circular. Therefore, during subsequent stripping, the outer sheath can be removed more easily and efficiently, and the cut of the cable will be neater, preventing the cut of the cable from being flat, which will make the subsequent crimping terminal effect better. After the cable length is determined, the first telescopic device 16 drives the arc plate 11 to move towards the cable. The arc plate 11 will press against the limiting plate 10, and the limiting plate 10 will compress the return spring 13. At the same time, it will drive the sliding column 9 and the cutter 6 to move synchronously. The cutter 6 will be pressed into the cable, which will facilitate the subsequent cutting and stripping of the cable. Before this, the cutter 6 will not contact the outer wall of the cable, which will facilitate the cable to pass through the main ring 4 and the secondary ring 5. When the cutter 6 revolves around the cable, the inclined cutting edge 7 can more easily slide along the outer wall of the cable. Since the main ring 4 and the secondary ring 5 rotate in opposite directions, the two sets of cutters 6 will cause the cable sheath to twist in a twisted shape, rather than rotating the entire cable sheath on the outer wall of the wire core. The twisting will cause the sheath to gradually separate from the wire core, so as to facilitate the subsequent stripping work. At the same time, after the sheath can no longer be twisted, the sheath is in a taut state, which makes it easier for the cutter 6 to complete the cutting of the sheath. For this purpose, the cutter 6 needs to rotate at least two revolutions on the outer wall of the cable.
