[0002] In fields such as modern electronic equipment and automobile manufacturing, wiring harnesses are key components of electrical connections, and their installation and processing efficiency are directly related to the production efficiency and final quality of the products.

[0003] In the traditional wiring harness installation process, the outer skin stripping of the wire harness usually relies on manual operation, which is not only inefficient, but also has many disadvantages. First, manual stripping requires high skills of the operator, and the difference in operation between different workers may lead to different stripping results, affecting the subsequent connection quality and reliability. Secondly, in the manual stripping process, if the force is not properly controlled, it is easy to cause insufficient cutting to expose the wire core, or excessive cutting to damage the wire core, which will directly affect the electrical performance and safety of the wire harness. In addition, long-term manual operation can easily cause worker fatigue and increase safety hazards in the workplace. Summary of the invention

[0004] The invention provides a wire harness installation device to solve the problem that manual wire harness stripping results in different stripping effects, thus affecting subsequent connection quality and reliability.

[0007] Furthermore, the fixing mechanism further comprises an electric slide block sliding on the installation box, the lower part of the electric slide block is connected to an electric telescopic rod, and the bottom end of the electric telescopic rod is connected to an electric clamp;

[0008] After the wiring harness is plugged into the threading block of the installation box, the electric telescopic rod is extended so that the electric clamp can clamp the wiring harness. After the electric clamp clamps the wiring harness, the full gear ring rotates and cuts off the outer skin of the wiring harness.

After the core of the wire harness is exposed, the plurality of electric clamps slide and clamp the core, and the mounting plate drives the threaded barrel to move so that the latch slides in the thread groove of the threaded barrel, so that the threaded barrel rotates to drive the electric clamps to move in a spiral trajectory to twist the core. When the mounting plate moves to the original position, the electric clamps reset and move away from the core.

[0013] Furthermore, the twisting mechanism also includes a cylinder, a cylinder rod of the cylinder is connected to a mounting frame, the mounting frame slides in the mounting box, the mounting frame is connected to a second rack, and the end of the second rack is connected to the mounting plate.

When the second rack moves relative to the mounting plate, the second rack can drive the toothless gear to drive the rotating shaft to rotate, so that the cam can press or move away from the pin, so that the pin can be inserted into or pulled out of the thread groove of the threaded barrel.

[0016] Furthermore, the twisting mechanism further comprises an inserting barrel and an inserting rod, wherein the inserting barrel is connected to the mounting plate, the inserting rod is inserted into the inserting barrel and connected to the second rack, a protrusion is arranged on the outer wall of the inserting rod, and a groove matching with the protrusion is arranged on the inner wall of the inserting barrel;

[0017] The insertion rod can slide relative to the insertion tube, and when the end of the insertion rod abuts against the mounting plate or the protrusion slides to the end of the groove on the inner wall of the insertion tube, the second rack drives the mounting plate to move synchronously.

[0019] When the mounting plate is reset, it can drive the sliding frame to move synchronously, so that the sliding frame drives the rectangular plate and the two clamping plates to approach the limiting plate. When the rectangular plate abuts against the limiting plate, the twisted wire core is inserted into the terminal, the sliding frame continues to move, and the two clamping plates approach each other to squeeze the terminal, so that the terminal is fixed to the wire core.

[0024] When in use, the wiring harness is separated so that the divided wiring harness is respectively inserted and connected in the installation box, and the length of the wiring harness insertion needs to exceed the position of the half-toothed ring. After the wiring harness is plugged in, the two half-toothed rings are controlled to be close to each other so that the two half-toothed rings form a full-toothed ring. When the two half-toothed rings form a full-toothed ring, the cutting knife connected to the inner wall of the two half-toothed rings can cut through the outer skin of the wiring harness, and then the full-toothed ring rotates, so that the cutting knife rotates along the wiring harness. At this time, the cutting knife cuts off the outer skin of the wiring harness end along the incision of the outer skin of the wiring harness, so that the outer skin of the end of the wiring harness can be peeled off to expose the wire core. By setting the exposed length of the cutting knife, the depth of the cutting knife cutting the outer skin of the wiring harness is controlled, which is convenient for cutting and stripping wiring harnesses with different outer skin thicknesses, thereby avoiding the problem of insufficient cutting or excessive cutting that may be caused by manual stripping, and at the same time improving the safety of wire stripping.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Examples, such as Figure 1-Figure 11 As shown, a wire harness installation device includes a fixing mechanism 100, the fixing mechanism 100 includes an installation box 110, a wire stripping mechanism 200 is arranged in the installation box 110, the wire stripping mechanism 200 includes two symmetrically arranged half-toothed rings 220, the inner walls of the two half-toothed rings 220 are connected with a cutting knife 230, the two half-toothed rings 220 can approach each other and form a full toothed ring, the installation box 110 is provided with a wire insertion hole coaxial with the full toothed ring, after the wire harness is inserted into the wire insertion hole, the two half-toothed rings 220 approach each other, the cutting knife 230 can penetrate the outer skin of the wire harness, and when the full toothed ring rotates, the cutting knife 230 can rotate around the wire harness, thereby cutting off the outer skin of the wire harness.

[0043] The working mechanism of the wiring harness installation device provided in this embodiment is as follows:

[0044] When in use, the wiring harness is separated so that the divided wiring harness is respectively inserted and connected in the installation box 110, and the length of the wiring harness insertion needs to exceed the position of the half-toothed ring 220. After the wiring harness is plugged in, the two half-toothed rings 220 are controlled to be close to each other so that the two half-toothed rings 220 form a full-toothed ring. When the two half-toothed rings 220 form a full-toothed ring, the cutting knife 230 connected to the inner wall of the two half-toothed rings 220 can cut through the outer skin of the wiring harness, and then the full-toothed ring rotates, so that the cutting knife 230 rotates along the wiring harness. At this time, the cutting knife 230 cuts off the outer skin of the wiring harness end along the incision of the outer skin of the wiring harness, so that the outer skin of the end of the wiring harness can be peeled off to expose the wire core. By setting the exposed length of the cutting knife 230, the depth of the cutting knife 230 cutting the outer skin of the wiring harness is controlled, which is convenient for cutting and stripping wiring harnesses with different outer skin thicknesses, thereby avoiding the problem of insufficient cutting or excessive cutting that may be caused by manual stripping, and at the same time improving the safety of wire stripping.

[0045] Regarding the structure of the fixing mechanism 100, specifically:

[0046] The fixing mechanism 100 also includes an electric slider 120 that slides on the installation box 110, and the lower part of the electric slider 120 is connected to an electric telescopic rod 130, and the bottom end of the electric telescopic rod 130 is connected to an electric clamp 140; after the wiring harness is plugged into the threading block of the installation box 110, the electric telescopic rod 130 is extended so that the electric clamp 140 can clamp the wiring harness, and after the electric clamp 140 clamps the wiring harness, the full gear ring rotates and cuts off the outer skin of the wiring harness. After the outer skin of the wiring harness is cut off, the electric slider 120 slides so that the electric clamp 140 pulls out the cut outer skin of the wiring harness, thereby exposing the wire core of the wiring harness.

[0047] A sensor is provided in the installation box 110. When the sensor detects that the depth of the wire harness inserted into the installation box 110 reaches the required depth, the electric telescopic rod 130 extends. When the electric telescopic rod 130 extends to the maximum length, the electric clamp 140 is just in the end position capable of clamping the wire harness. At this time, the electric clamp 140 clamps the wire harness so that the end of the wire harness is fixed, and a pulling force is applied to the part of the wire harness outside the installation box 110, or another clamp is provided on the outer wall of the installation box 110 to clamp the wire harness so that the wire harness is in a taut state, thereby ensuring the stability when the outer skin of the wire harness is cut. When the full gear ring rotates and After the outer skin of the wire harness end is cut off, the electric slider 120 slides and drives the electric clamp 140 away from the wire harness end. At this time, the electric clamp 140 clamps the outer skin of the wire harness after the ring cutting and pulls the wire harness out. While the electric slider 120 slides, the electric telescopic rod 130 is also shortened, so that the electric slider 120 does not need to slide a long distance and the electric clamp 140 can be far away from the wire harness end. When the electric clamp 140 moves the set stroke, the outer skin of the wire harness end is completely peeled off, and the wire core of the wire harness is exposed. At the same time, the electric clamp 140 maintains its position to ensure that it does not interfere with the operation of the subsequent other components.

[0048] In addition, the electric clamp 140 can also be set with another program to control it to transport the clamped wire harness sheath to the outside of the installation box 110 to ensure the continuity of the operation.

[0049] Regarding the structure of the wire stripping mechanism 200, specifically:

[0050] The wire stripping mechanism 200 also includes a first limiting rod 221 and a second limiting rod 222, and the two half-toothed rings 220 are connected to the first limiting rod 221 and the second limiting rod 222. The installation box 110 is provided with a first slide groove 240 and a second slide groove 250, and the first slide groove 240 and the second slide groove 250 are both composed of a straight segment and an arc segment; the installation box 110 is symmetrically connected in the vertical direction with two first racks 210 that are horizontally slidable, and the two first racks 210 can slide synchronously and in opposite directions, and the two first racks 210 are respectively connected to the two half-toothed rings 2 20 meshing, when the two first racks 210 slide toward each other, they can drive the first limiting rod 221 and the second limiting rod 222 on the two half-toothed rings 220 to slide on the straight sections of the first slide groove 240 and the second slide groove 250 respectively, so that the two half-toothed rings 220 approach each other to form a full toothed ring, and, after the two half-toothed rings 220 contact, the first limiting rod 221 and the second limiting rod 222 slide to the arc sections of the first slide groove 240 and the second slide groove 250 respectively, and when the two first racks 210 continue to slide toward each other, they can drive the full toothed ring to rotate, thereby cutting off the outer skin of the wiring harness.

[0051] The two first racks 210 are driven by an electric push rod or a screw rod to achieve synchronous and reverse sliding in the installation box 110. When the two half-toothed rings 220 are in a separated state, the two first racks 210 are close to each other. At this time, the first limiting rod 221 and the second limiting rod 222 slide in the straight sections of the first slide groove 240 and the second slide groove 250 respectively. The half-toothed ring 220 is limited by the first limiting rod 221 and the second limiting rod 222 and will not rotate. At this time, the two first racks 210 can drive the two half-toothed rings 220 to move. The rings 220 approach each other, and when the two half-toothed rings 220 approach each other and contact each other, the first limit rod 221 and the second limit rod 222 slide to the arc segments of the first slide groove 240 and the second slide groove 250 respectively. At this time, the first rack 210 continues to slide, and the first limit rod 221 and the second limit rod 222 can slide inside the arc segments of the first slide groove 240 and the second slide groove 250 respectively. At this time, the first rack 210 can drive the full toothed ring to rotate, so that the cutting knife 230 cuts off the end skin of the wiring harness.

[0052] Regarding the structure of the twisting mechanism 300, specifically:

[0053] The wire twisting mechanism 300 includes a limit plate 320 fixedly connected to the installation box 110 and a mounting plate 310 slidably connected to the installation box 110. A threaded barrel 340 is rotatably connected to the mounting plate 310. A hole coaxially arranged with the threaded barrel 340 is opened on the mounting plate 310. The wiring harness passes through the mounting plate 310 and the threaded barrel 340. A latch 380 is slidably connected to the limit plate 320, and the latch 380 can slide in the thread groove of the threaded barrel 340; a plurality of electric clamps 341 arranged radially for sliding are connected to the threaded barrel 340. After the wire core of the wiring harness is exposed, the plurality of electric clamps 341 slide and clamp the wire core, and the mounting plate 310 drives the threaded barrel 340 to move so that the latch 380 slides in the thread groove of the threaded barrel 340, so that the threaded barrel 340 rotates to drive the electric clamp 341 to move in a spiral trajectory to twist the wire core. When the mounting plate 310 moves to the original position, the electric clamp 341 resets and moves away from the wire core.

[0054] When the outer sheath of the wire harness is cut off, the exposed part of the wire core of the wire harness is in the threaded barrel 340. After the control system receives the signal that the electric clamp 140 is away from the wire harness, it controls the multiple electric clamps 341 to slide radially and approach each other, so that the multiple electric clamps 341 squeeze the wire core of the wire harness. Then the mounting plate 310 moves away from the semi-toothed ring 220. At this time, the mounting plate 310 drives the threaded barrel 340 to slide axially in the hole of the limit plate 320, and the pin 380 connected to the limit plate 320 slides in the thread groove of the threaded barrel 340. , so that it can rotate when the threaded barrel 340 slides axially. At this time, multiple electric clamps 341 all move in a spiral trajectory. At this time, the electric clamps 341 have squeezed the wire core, so that the wire core can be twisted when the electric clamps 341 moves, ensuring that the wire core is in a coaxial position with the threaded barrel 340 after twisting, which is convenient for the subsequent terminal connection. When the wire core is twisted, the mounting plate 310 moves in the opposite direction. At this time, the electric clamps 341 in the threaded barrel 340 are reset and away from the twisted wire core, thereby ensuring that the position of the wire core after twisting will not change significantly.

[0055] Among the optional methods of this embodiment, the more preferred ones are:

[0056] The twisting mechanism 300 also includes a cylinder 330 , a cylinder rod of the cylinder 330 is connected to a mounting frame 350 , the mounting frame 350 slides in the mounting box 110 , a second rack 360 is connected to the mounting frame 350 , and an end of the second rack 360 is connected to the mounting plate 310 .

[0057] When the cylinder 330 is in operation, it can drive the mounting plate 310 to move through the mounting frame 350 and the second rack 360 , so that the mounting plate 310 is driven to move closer to or away from the semi-gear ring 220 .

[0058] Among the optional methods of this embodiment, the more preferred ones are:

[0059] The twisting mechanism 300 also includes a rotating shaft 370, which is connected to a cam 373. The end of the rotating shaft 370 is connected to a toothed gear 371, which meshes with the second rack 360. A torsion spring 372 is connected between the toothed gear 371 and the mounting box 110, and a first spring 381 is connected between the pin cap of the latch 380 and the limit plate 320; when the second rack 360 slides to the end of its stroke and changes the sliding direction, the second rack 360 first moves relative to the mounting plate 310, and then drives the mounting plate 310 to move synchronously. When the second rack 360 moves relative to the mounting plate 310, the second rack 360 can drive the toothed gear 371 to drive the rotating shaft 370 to rotate, so that the cam 373 can press or move away from the latch 380, so that the latch 380 can be inserted into or pulled out of the thread groove of the threaded barrel 340.

[0060] When the second rack 360 reaches the two ends of the sliding stroke and initially slides in the opposite direction, it does not drive the mounting plate 310 to move, so that the threaded cylinder 340 connected to the mounting plate 310 does not move at this time. The initial sliding of the second rack 360 can drive the toothless gear 371 to rotate first, and when the toothless gear 371 rotates, it can drive the rotating shaft 370 to rotate synchronously. At this time, the cam 373 on the rotating shaft 370 rotates synchronously. When the second rack 360 moves in the direction away from the mounting plate 310, the second rack 360 drives the cam 373 to rotate and causes the cam 373 to press the latch 380, so that the latch 380 is inserted into the thread groove of the threaded cylinder 340, and then the second rack 360 continues to move. At this time, the second rack 360 is close to the toothless part of the toothless gear 371, so it will not continue to drive the toothless gear 371 to continue to rotate. The toothless gear 371 passes The torsion spring 372 is connected to the installation box 110. At this time, the teeth of the second rack 360 continue to move to contact and push the teeth at one end of the toothless gear 371 to ensure the position stability of the cam 373, so that the pin 380 is stably inserted in the threaded groove of the threaded barrel 340. When the second rack 360 moves in the opposite direction, due to the action of the torsion spring 372, the toothless gear 371 is still meshed with the second rack 360. At this time, the second rack 360 drives the toothless gear 371 to rotate in the opposite direction, so that the cam 373 moves away from the pin 380, and the first spring 381 lifts the pin 380, so that the pin 380 is disengaged from the threaded groove of the threaded barrel 340. Then the second rack 360 drives the mounting plate 310 to move, so that the movement resistance of the threaded barrel 340 is reduced, so that the energy consumption of the device is reduced, and the wear of the threaded groove of the threaded barrel 340 is reduced.

[0061] Among the optional methods of this embodiment, the more preferred ones are:

[0062] The twisting mechanism 300 also includes an insertion tube 311 and an insertion rod 361. The insertion tube 311 is connected to the mounting plate 310. The insertion rod 361 is inserted into the insertion tube 311 and connected to the second rack 360. A protrusion 362 is provided on the outer wall of the insertion rod 361, and a groove matching the protrusion 362 is provided on the inner wall of the insertion tube 311. The insertion rod 361 can slide relative to the insertion tube 311, and when the end of the insertion rod 361 abuts against the mounting plate 310 or the protrusion 362 slides to the end of the groove on the inner wall of the insertion tube 311, the second rack 360 drives the mounting plate 310 to move synchronously.

[0063] When the second rack 360 moves, the insertion rod 361 connected to the second rack 360 moves synchronously. When the second rack 360 moves in the direction away from the mounting plate 310, the insertion rod 361 first slides in the insertion tube 311. At this time, the second rack 360 drives the toothless gear 371 to rotate. When the protrusion 362 of the insertion rod 361 slides to the end of the groove in the insertion tube 311, the second rack 360 can drive the mounting plate 310 to move synchronously. When the second rack 360 moves in the opposite direction, the insertion rod 361 first slides in the direction close to the mounting plate 310. At this time, the second rack 360 drives the toothless gear 371 to rotate in the opposite direction, so that the cam 373 moves away from the pin 380. When the pin 380 pops out, the end of the insertion rod 361 abuts against the mounting plate 310. At this time, the second rack 360 can push the mounting plate 310 to move to reset.

[0064] Regarding the structure of the terminal mounting mechanism 400, specifically:

[0065] The terminal installation mechanism 400 includes a rectangular plate 430, two sliding frames 410 and a clamping plate 420 sliding between the two sliding frames 410, the rectangular plate 430 is connected with a pin 431, the pin 431 passes through the sliding frame 410, and a second spring 432 is sleeved on the pin 431, the two ends of the second spring 432 respectively abut against the rectangular plate 430 and the sliding frame 410, and the two clamping plates 420 are connected with an arc plate 422, the terminal is placed between the two arc plates 422, and the hole of the terminal is opposite to the twisted wire core; when the installation plate 310 is reset, the sliding frame 410 can be driven to move synchronously, so that the sliding frame 410 drives the rectangular plate 430 and the two clamping plates 420 to approach the limit plate 320, when the rectangular plate 430 abuts against the limit plate 320, the twisted wire core is inserted into the terminal, the sliding frame 410 continues to move, and the two clamping plates 420 approach each other to squeeze the terminal, so that the terminal is fixed to the wire core.

[0066] When the mounting plate 310 starts to reset, the sliding frame 410 moves synchronously with the mounting plate 310. At this time, the sliding frame 410 drives the rectangular plate 430 and the two clamping plates 420 to approach the limit plate 320, so that the terminal placed between the two clamping plates 420 can be sleeved on the twisted wire core. As the sliding frame 410 continues to slide, the rectangular plate 430 can abut against the limit plate 320, and the sliding frame 410 continues to slide, so that the sliding frame 410 compresses the second spring 432 and approaches the rectangular plate 430. At this time, the two clamping plates 420 can approach each other, so that the two arc plates 422 approach each other synchronously, squeezing the terminal on the wire core, thereby completing the installation of the terminal. When the sliding frame 410 moves away from the limit plate 320, the elastic force of the second spring 432 is released first. At this time, the two clamping plates 420 move away from each other, thereby preventing the installed terminal from being torn off.

[0067] Among the optional methods of this embodiment, the more preferred ones are:

[0068] The terminal installation mechanism 400 also includes two first wedge blocks 433 and two second wedge blocks 421. The two first wedge blocks 433 are respectively connected to the upper and lower parts of the rectangular plate 430, and the two second wedge blocks 421 are respectively connected to the two clamping plates 420. When the sliding frame 410 approaches the rectangular plate 430, the second wedge blocks 421 slide relative to the first wedge blocks 433, so that the two clamping plates 420 approach each other.

[0069] The two clamping plates 420 are supported by elastic components, such as springs, air bags, etc. When the sliding frame 410 approaches the rectangular plate 430, the first wedge block 433 on the rectangular plate 430 guides and squeezes the second wedge block 421 on the clamping plate 420, so that the two clamping plates 420 are close to each other. When the sliding frame 410 moves away from the rectangular plate 430, the elastic component pushes the two clamping plates 420, so that the two clamping plates 420 move away from each other.

[0070] Among the optional methods of this embodiment, the more preferred ones are:

[0071] The terminal installation mechanism 400 also includes a magnet 440, a bracket 450 and a tension spring 451. The magnet 440 is connected to the cylinder rod of the cylinder 330, the bracket 450 is connected to the installation box 110, and the two ends of the tension spring 451 are respectively connected to the bracket 450 and the sliding frame 410. When the cylinder rod of the cylinder 330 is shortened and then extended, the magnet 440 is adsorbed on the sliding frame 410 and drives the sliding frame 410 to move synchronously so that the tension spring 451 is stretched. When the cylinder rod of the cylinder 330 continues to extend, the magnet 440 is separated from the sliding frame 410, so that the tension spring 451 contracts to reset the terminal installation mechanism 400.

[0072] When the cylinder 330 is shortened, it drives the twisting mechanism 300 to twist the wire core. At this time, the magnet 440 on the cylinder rod of the cylinder 330 is close to the sliding frame 410. When the cylinder 330 is about to shorten the maximum stroke, the magnet 440 can absorb the sliding frame 410. Then the cylinder 330 extends, so that the magnet 440 drives the sliding frame 410 to approach the limit plate 320. After the terminal is installed on the wire core, the cylinder rod continues to extend. At this time, the sliding frame 410 is blocked by the rectangular plate 430, so that the magnet 440 can then detach from the sliding frame 410. After the magnet 440 detaches from the sliding frame 410, the elasticity of the tension spring 451 is released, so that the sliding frame 410 is pulled, so that the terminal installation mechanism 400 is reset.
