Technical Field

[0002] ‌‌Wire harness is a combination of multiple wires or cables, which is used to connect various components of electrical equipment to achieve normal operation of electrical equipment. Wire harness is widely used in many fields, such as electronic equipment, automobile and aerospace industries.

[0003] Typically, a wiring harness includes at least a protective sheath (such as rubber, plastic or metal braid) and a plurality of wires, which are wrapped and gathered by the protective sheath. For ease of connection, the end of each wire protrudes out of the protective sheath. The wires typically also include an outer insulating layer and an inner wire core.

[0004] At present, according to actual application requirements, it is necessary to process multiple wires exposed outside the protective sheath, wherein the processing specifically includes three steps: stripping, cutting and tinning. Peeling is to facilitate cutting, cutting is to ensure that the multiple wires exposed outside the protective sheath are flush, and tinning is to prevent oxidation of the wires and improve tensile strength.

[0005] At present, the processing of the wires of the wiring harness is usually done manually. Workers use special scissors for stripping to manually strip the wires, and then use shearing tools such as scissors to cut the wires. Finally, they hold the protective jacket to suspend the wires in the tin furnace for tinning.

The receiving holes 52 are specifically semicircular holes, and the receiving holes 52 penetrate the mounting block 51.

The limiting member 53 is used for allowing the protective jackets of multiple wiring harnesses to abut against each other so that the multiple protective jackets can be flush. Specifically, the limiting member 53 is provided with a corresponding accommodating semicircular hole 531 corresponding to each receiving hole 52. The accommodating semicircular hole 531 is coaxially arranged with the receiving hole 52, and the aperture of the accommodating semicircular hole 531 is smaller than the receiving hole 52. After the wiring harness is placed in each receiving hole 52, it is first necessary to ensure that the three wire cores of each wiring harness are all inserted into the accommodating semicircular hole 531, and then all the wiring harnesses are moved to the left so that all the protective jackets abut against the limiting member 53. At this time, the multiple protective jackets will be flush.

[0042] Reference Figure 2 and Figure 3, a mounting member 54 is provided at the end of the stopper 53 away from the mounting block 51, and the mounting member 54 is used to support the wire core; in order to arrange the wire core for subsequent cutting, a vertical plate 55 is provided on the mounting member 54, and a plurality of receiving holes 551 for receiving the wire core are opened at the top of the vertical plate 55.

The pressing and cutting component 34 can cut off the exposed wire core.

[0045] Reference Figure 5 The limiting component 32 includes a tray 321 arranged on the frame 31, and the tray 321 includes a receiving groove 322 at the top. The mounting block 51 can be fitly placed in the receiving groove 322, and the mounting block 51 can be moved and taken out.

[0046] Reference Figure 4 The facelift assembly 33 includes a driving member 331 disposed on the frame 31, the driving member 331 is preferably a cylinder, and the driving member 331 is connected to a pressing member 332, combined with Figure 2 The pressing member 332 is located above the pressing cover 561, and the driving member 1 331 is used to drive the pressing member 332 to move downward to press the pressing cover 561. The pressing member 332 will press the pressing cover 561 to compress the multiple wire harnesses, and at this time, the mounting block 51 is also pressed on the tray 321, and the mounting block 51 cannot move.

[0047] Reference Figure 5 and Figure 6The facelift assembly 33 also includes a sliding block 333 disposed on the frame 31 and slidably connected to the frame 31. The sliding block 333 is provided with a mounting seat 334, and the mounting seat 334 is rotatably connected to a push-up lever 335; the push-up lever 335 includes a pressing portion 3351 and a clamping portion 3352, the pressing portion 3351 and the clamping portion 3352 are respectively located on both sides of the mounting seat 334, an upper jaw 33521 is provided on the clamping portion 3352, and a lower jaw 3331 is provided on the sliding block 333; the pressing portion 3351 is connected to a reciprocating The feeding member 336, the reciprocating feeding member 336 is preferably a thin cylinder, and the output shaft of the thin cylinder can be designed to be able to rotate slightly to meet the requirement of driving the pressure-tilting rod 335 to press around the mounting seat 334 in this application. The output end of the reciprocating feeding member 336 is connected to the sliding block 333, and the reciprocating feeding member 336 can drive the pressure-tilting rod 335 to rotate, thereby driving the upper jaw 33521 to approach / move away from the lower jaw 3331; a reciprocating feeding group 337 connected to the sliding block 333 is also provided on the frame 31.

[0048] Reference Figure 5 and Figure 6 The reciprocating feeding group 337 includes a connecting seat 3371 connected to the frame 31, and a reciprocating feeding member 2 3372 and a reciprocating feeding member 3 3373 are provided on the connecting seat 3371, and the reciprocating feeding member 2 3372 and the reciprocating feeding member 3 3373 are preferably cylinders; the output shaft of the reciprocating feeding member 2 3372 is connected to the frame 31, so the reciprocating feeding member 2 3372 can drive the connecting seat 3371 to move left and right; the output shaft of the reciprocating feeding member 3 3373 is connected to the sliding block 333, so the reciprocating feeding member 3 3373 can drive the sliding block 333 to move left and right. In this embodiment, the output power of the reciprocating feed member 2 3372 is mainly used to pull the cut cortex to expose the internal wire core, so the output shaft movement stroke of the reciprocating feed member 2 3372 is set to be smaller, and the output power of the reciprocating feed member 3 373 is mainly used to move the upper jaw 33521 and the lower jaw 3331 to the two sides of the cortex to be pulled and to reset, so the output shaft movement stroke of the reciprocating feed member 3 3373 is set to be larger.

[0049] The present application can realize the following actions: first, the driving member 1 331 is driven to drive the pressing member 332 to move so as to press the pressing cover 561 to ensure that the pressing cover 561 presses the multiple wire harnesses; then, the reciprocating feeding member 3373 is driven to drive the sliding block 333 to move so that the multiple cut leather layers are located between the upper jaw 33521 and the lower jaw 3331, and then the reciprocating feeding member 1 336 is driven to drive the upper jaw 33521 and the lower jaw 3331 to move closer to each other to clamp the cut leather layers; then, the reciprocating feeding member 2 3372 is driven to drive the sliding block 333 to move the cut leather layers. The cut cortex is pulled a certain distance so that part of the wire core structure is exposed. At this time, it is necessary to ensure that the cut cortex is not completely separated from the wire core, and the wire core and the cut cortex are still partially connected; then the reciprocating feed member 1 336 is driven to drive the upper jaw 33521 and the lower jaw 3331 to move away from each other to release the clamping of the cortex, and then the reciprocating feed member 3373 is driven to drive the sliding block 333 to move and drive the upper jaw 33521 and the lower jaw 3331 to reset. At this time, the pressing and cutting assembly 34 is used to cut off the exposed wire core, and the cut wire core will fall off with the cortex.

[0050] The wire core is usually small and thin, and the cut wire core is long or short. If the wire core is cut off alone and falls on the ground or any structure, the wire core will be difficult to collect and find. In addition, the wire core is also light, and the cut wire core is easily affected by external factors such as wind and flies around. Therefore, in the present application, the cortex and the wire core are not completely separated after being cut to ensure that they can be easily found and collected after falling. The heavier core with cortex can also avoid the flying of the cut cortex and wire core waste to a certain extent.

[0051] Reference Figure 6 In order to facilitate the upper jaw 33521 and the lower jaw 3331 to clamp the cortex, the lower end of the upper jaw 33521 has a plurality of sawtooth grooves 33522 for increasing friction, and the sawtooth grooves 33522 are inclined downward toward the direction close to the mounting seat 334.

[0052] Reference Figure 4 The pressing and cutting assembly 34 includes a second driving member 341 disposed on the frame 31, the second driving member 341 is a cylinder, and the second driving member 341 is connected to a cutting knife 342, combined with Figure 2 The second driving member 341 is used to drive the cutting knife 342 to move vertically so as to cut the wire core along the left end of the vertical plate 55. The specific structure of the cutting knife 342 is prior art and will not be described here.

[0053] Reference Figure 3 Combined with Figure 1The skin cutting mechanism 2 in this application is a laser cutting machine. In order to cooperate with the use of the laser cutting machine, a through groove 541 is opened on the mounting part 54. The through groove 541 is vertically arranged. The through groove 541 is located between the pressure cover 561 and the accommodating semicircular hole 531. The through groove 541 is used for the laser cutting machine to emit laser to pass through and thus cut the skin layer.

[0054] In the present application, after cutting half of the circumference of the wire harness by using a laser cutting machine, the skin-lifting assembly 33 can be used to pull the skin layer to expose the wire core part, which can meet the subsequent wire core cutting requirements; of course, the entire circumference of the wire harness can also be cut by flipping the tray mechanism 5, and the subsequent wire core can be exposed more. The specific cutting method is determined based on the thickness of the skin layer. When the thickness of the skin layer is large, the latter cutting method is selected for cutting.

The tinning method using the positioning component 46 can ensure that the distance of multiple wire cores immersed in the tin liquid is controllable.

[0062] The implementation principle of a wire harness processing device in the embodiment of the present application is: First, rotate the pressing column 563 to remove the pressing cover 561, then place the multiple wire harnesses in the multiple receiving holes 551 and move the multiple wire harnesses so that the multiple protective jackets are against the stopper 53. At this time, the multiple protective jackets will be flush, and each wire is placed in one of the receiving semicircular holes 531 to arrange the wires. Then, reset the pressing cover 561 and rotate the pressing column 563 to press the pressing cover 561. Place the mounting block 51 on the skin cutting mechanism 2 to cut the skin layer; The mounting block 51 is placed in the receiving groove 322, and the driving member 1 331 is driven to drive the pressing member 332 to move and press against the pressing cover 561 to press the multiple wire harnesses; then the reciprocating feeding member 3373 is driven to drive the sliding block 333 to move so that the multiple cut leather layers are located between the upper jaw 33521 and the lower jaw 3331, and then the reciprocating feeding member 1 336 is driven to drive the upper jaw 33521 and the lower jaw 3331 to move closer to each other to clamp the cut leather layers; then the reciprocating feeding member 2 3372 is driven to drive the sliding block 333 to move the cut leather layers to be pulled a certain distance so that part of the wire core is knotted. The structure is exposed. At this time, it is necessary to ensure that the cut cortex is not completely separated from the wire core, and the wire core and the cut cortex are still partially connected; then the reciprocating feed member 1 336 is driven to drive the upper jaw 33521 and the lower jaw 3331 to move away from each other to release the clamping of the cortex, and then the reciprocating feed member 3373 is driven to drive the sliding block 333 to move and drive the upper jaw 33521 and the lower jaw 3331 to reset, and then the driving member 2 341 is driven to drive the cutting knife 342 to move vertically, so as to cut the wire core along the left end of the vertical plate 55 to cut the exposed wire core, and the cut wire core will fall off with the cortex; The driving member 331 drives the pressing member 332 to move and release the tightness of the pressing cover 561, and the mounting block 51 is disassembled and inserted into the plug-in slot 4522 until the clamping column 511 is against the wall of the clamping slot 4521. At this time, it is necessary to ensure that the wire core to be tinned faces downward, and then rotate the twist cap 464 to drive the connecting block 451 to approach / move away from the tin furnace 41, thereby driving the wire core to synchronously approach / move away from the tin furnace 41 for tinning.
