Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to an integrated device for stripping, cutting, folding, brushing, straightening and trimming new energy wire harnesses. Background Art

[0002] As a coaxial harness, the new energy wiring harness is composed of a central conductor, an inner insulation layer, a shielding layer, an aluminum foil layer and an outer insulation layer. When processing the new energy wiring harness, the outer insulation layer, the aluminum foil layer, the shielding layer and the inner insulation layer need to be cut and stripped in turn before proceeding to the next step;

[0003] In the related art, when processing the coaxial cable harness, a multi-layer cutter arranged along the length direction of the cable is usually used for processing, that is, the outer insulation layer and the aluminum foil layer are first cut and peeled off with the first layer of cutters, and then the shielding layer is processed with the second layer of cutters, and finally the inner insulation layer is peeled off;

[0004] In the design process of new energy vehicle wiring harness, the technology of pressing the inner and outer shielding rings together with the shielding layer is used to realize the connection between the shielding layer and other wire layers after the cable stripping process. The outer diameter of the inner shielding ring, the diameter of the aluminum foil layer, and the inner diameter of the outer shielding ring are the key dimensions that affect the assembly of the shielding ring. The ideal manufacturing process is that the inner shielding ring is passed through the inner insulating layer. After the shielding layer is cut, the shielding layer is dispersed from the braided state into a single strand of shielding wire, folded onto the inner ring, and the outer shielding ring is passed through the shielding wire. The shielding layer of the wire is fixed and crimped on the inner insulating layer. In order to ensure the reliable quality of the wire harness processing, the shielding wire is exposed to the shielding ring after crimping, and the exposed size is ≤1mm, and no single shielding wire is exposed to prevent the shielding layer from adhering to the inner conductor to form a short circuit.

[0005] The above-mentioned wire harness processing technology requirements have strict requirements on the processing of the shielding layer of the wire. After the shielding layer is cut, it is dispersed from the braided state to a single straight state, and the folding between the inner and outer shielding rings is the key manufacturing process of the wire harness manufacturer.

[0006] At present, the processing of wire harness cutting equipment will produce a large amount of aluminum foil residue ≥3mm, which will affect the assembly of inner and outer shielding rings in the subsequent process. During the production process, personnel need to be arranged to check and trim the aluminum foil residue. If the braiding state of the shielding layer remains unchanged after the shielding layer is cut, it will affect the difficulty of assembling the inner and outer shielding rings.

DETAILED DESCRIPTION

[0037] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0038] Figure 1 The overall structure of the new energy wire harness stripping, cutting, folding, brushing, straightening and trimming integrated device is schematically shown. A new energy wire harness stripping, cutting, folding, brushing, straightening and trimming integrated device is shown. Figure 1 As shown, it includes a workbench 1 and a cutter disc cutting unit 4 fixedly arranged on the workbench 1, based on the two sides of the cutter disc cutting unit 4, respectively, there are movably fixed cooperable punch components 5 and die components 3, and a wire-supporting clamping claw unit 2 is movably fixed on the same side of the die component 3. The new energy wire harness is clamped by the wire-supporting clamping claw and sent into the cutter disc cutting unit 4 to cut and strip the outer insulation layer, aluminum foil layer, shielding layer and inner insulation layer in turn, and when stripping the shielding layer, the new energy wire harness needs to pass through the die component 3 and then extend into the cutter disc cutting unit 4 to complete partial stripping of the shielding net, and the die component 3 and the punch component 5 cooperate to complete the folding of the shielding net, and in the aforementioned process, the wire harness is fixed and shifted by the wire-supporting clamping claw unit 2 throughout the entire process.

[0039] Figure 2 The overall structure of the blade cutting unit 4 is schematically shown. Figure 2The blade cutting unit 4 will be described in detail. The cutter disc cutting unit 4 includes a multi-layer cutter disc, on which a cutter holder unit 41 and a wire clamp unit 42 are movably fixed. The cutter holder unit 41 includes a cutting knife 412 and a rolling knife 413 arranged at different positions on a cutter holder bracket 411. The cutting knife 412 or the rolling knife 413 is fitted with the outer edge of the wire harness, and the outer insulation layer, the aluminum foil layer and the inner insulation layer of the wire harness are stripped by the cutting knife 412. The part of the shielding layer of the wire harness is stripped by applying the rolling knife 413. The wire clamp unit 42 can reciprocate along the radial direction of the cutter disc, and the wire clamp unit 42 is also fitted with the outer edge of the wire harness. After the front end of the wire harness is clamped by the wire clamp unit 42, the outer insulation layer, the aluminum foil layer, the shielding layer and the inner insulation layer are cut and stripped in turn by the cutting knife 412 or the rolling knife 413, and the fitting of the aforementioned cutter holder unit 41 and the wire clamp unit 42 with the outer edge of the wire harness is adjusted by the multi-layer cutter disc, thereby adjusting the stripping action of the outer insulation layer, the aluminum foil layer, the shielding layer and the inner insulation layer.

[0040] Figure 3 The overall structure of the tool holder unit 41 is schematically shown. Figure 3 The tool holder unit 41 is described in detail. The tool holder unit 41 also includes a connecting plate 414. Pins are provided at both ends of the connecting plate 414. The pins on one side of the connecting plate 414 are movably fixed to the multi-layer tool holder, and the tool holder bracket 411 is movably fixed to the pins on the other side. A positioning pin 415 is embedded in the tool holder bracket 411. The cutting knife 412 and the ingot knife are fixedly provided at different positions on the same end of the tool holder bracket 411, and the cutting knife 412 and the rolling knife 413 are oriented in different directions. More specifically, the cutting knife 412 , the roller cutter 413 and the tool holder bracket 411 are arranged in a triangle at a fixed position on the connecting plate 414. After the position of the positioning pin shaft 415 is fixed, the connecting plate 414 changes its position under the rotation of the multi-layer cutter disc, so that the cutting knife 412 and the roller cutter 413 can present different orientations and as much as possible. This is the tool changing process and the tool feeding process of the utility model. It is obvious that the tool changing process depends on the rotation of the multi-layer cutter disc, and the tool feeding process requires the addition of a limit groove on the multi-layer cutter disc.

[0041] Figure 4 The schematic diagram shows the overlapping structure of the second blade disc 44 and the third blade disc 45. Figure 4The multi-layer cutter disc is described in detail. The multi-layer cutter disc is formed by the first cutter disc 43, the second cutter disc 44 and the third cutter disc 45 being coaxially fixed in sequence. A fixed disc 46 is fixedly arranged at the center of the multi-layer cutter disc. The fixed disc 46 and the multi-layer cutter disc can be connected by bearings. A plurality of wire clamp units 42 are arranged along the radial direction of the fixed disc 46. The fixed disc 46 is flush with the third cutter disc 45. A third limiting groove 451 is opened on the third cutter disc 45, which gradually approaches the center. The tail of the wire clamp unit 42 fits tightly with the outer edge of the third limiting groove 451. To achieve the above-mentioned tight fit, an elastic structure needs to be provided in the wire clamp unit 42, so that when the tail of the wire clamp unit 42 is always in tight fit with the outer edge of the third limit slot 451, and due to the rotation of the third blade disc 45, the outer diameter of the third limit slot 451 is in a state of continuous reduction, which can push the wire clamp unit 42 elastically fixed on the fixed disk 46 toward the center of the third blade disc 45, so that the wire harness located therein is locked and fixed by multiple wire clamp units 42. And due to the existence of the elastic structure, when the outer diameter of the third limit slot 451 gradually increases when the third blade disc 45 rotates, the tail of the wire clamp unit 42 can still always be in tight fit with the outer edge of the third limit slot 451. The aforementioned third blade disc 45 is driven by a separate servo motor in conjunction with a belt, and the number of the third limit slots 451 is the same as the number of wire clamp units 42.

[0042] In some embodiments, the third blade disc 45 is provided with second limiting grooves 441 having the same number as the blade holder unit 41, and the second limiting grooves 441 include a first arc segment 4411 and a second arc segment 4412, the edges of the first arc segment 4411 and the second arc segment 4412 are smoothly connected, and the second arc segment 4412 is wider than the first arc segment 4411, and it is worth noting that the outer diameter of the second arc segment 4412 is the same as that of the first arc segment 4411, and the width of the second arc segment 4412 gradually increases as it moves away from the first arc segment 4411. The tail of the tool holder unit 41 is fixed to the second tool disc 44 by a connecting plate 414 cooperating with a pin shaft passing through the third limiting groove 441, and a fixed shaft is placed in the second limiting groove 441 on the side of the connecting plate 414 facing away from the tool holder unit 41. The head of the tool holder unit 41 is movably fixed to the fixed plate 46 by bolts, and an annular groove is provided on the fixed plate 46 to limit the rotation angle of the head of the tool holder unit 41, and a limiting shaft is provided on the side of the connecting plate 414 facing away from the tool holder unit 41, the limiting shaft is located in the second limiting groove 441, and an elastic component is provided between the connecting plate 414 and the pin shaft to make the side of the connecting plate 414 with the limiting shaft tightly attached to the inner diameter side of the second limiting groove 441. Through the movement of the connecting plate 414 in the first arc segment 4411, any one of the cutting knife 412 and the rolling knife 413 in the tool holder unit 41 is adjusted to face the wiring harness, and the feed amount is adjusted according to the width of the second arc segment 4412. In this process, the first cutter disc 43 and the second cutter disc 44 need to rotate in coordination. The utility model does not specifically limit the shape of the slot here, and it is only required that it does not affect the tool change and feed process. The aforementioned first cutter disc 43 and the second cutter disc 44 are driven by a separate servo motor in conjunction with a belt, and the number of the second limiting grooves 441 is the same as the number of the tool holder unit 41. In other embodiments, the aforementioned second limiting groove 441 is set on the second cutter disc 44, and a notch that penetrates the thickness of the third cutter disc 45 is correspondingly opened on the third cutter disc 45 so as not to affect the feed process, and the fixed disc 46 is movably fixed with a bearing and a multi-layer cutter disc.

[0043] Figure 5 The overall structure of the male mold assembly 5 is schematically shown, combined with Figure 5The punch assembly 5 is described in detail. The punch assembly 5 includes a fixed platform 51 and a positioning seat 52 that can reciprocate along the length direction of the fixed platform 51.

The positioning seat 52 is driven by a screw assembly to move along the length direction of the fixed platform 51, and the screw is driven by a motor. A guide rod 53 is fixed on the side of the positioning seat 52 facing the cutter disc cutting unit 4 through a quick-change tool. A punch 54 is mounted on the guide rod 53, and a sensor for detecting the wiring harness is provided in the guide rod 53. The punch 54 is connected to a cylinder through a connecting rod, and is connected to a motor fixed on the positioning seat 52 through another connecting rod. The punch 54 can be driven to reciprocate along the length direction of the guide rod 53 through the cylinder and the connecting rod, and the punch 54 can be adjusted to rotate around the guide rod 53 by a certain angle by the motor and the connecting rod.

[0044] Figure 6 The overall structure of the die assembly 6 is schematically shown, combined with Figure 6 The die assembly 3 is described in detail. The die assembly 3 includes a die base plate 31 disposed in front of the cutter disc cutting unit 4. A slide rail and a die bracket 32 ​​are vertically disposed on the die base plate 31. The die is embedded in the die bracket 32. The die bracket 32 ​​is driven by a cylinder to reciprocate along the length direction of the slide rail. It is worth noting that the outer edge surface of the die is an inner concave structure. When the die is embedded in the die bracket 32, the die is locked in the die bracket 32 ​​by a die quick-change tool pressed from the top of the die bracket 32.

[0045] Figure 7 The schematic diagram shows the assembly of the male mold assembly 5 and the female mold assembly 6. Driven by the wire clamping claw unit 2, the wire harness enters the cutter head cutting unit 4 from the through hole penetrating the thickness direction of the female mold, and the shielding layer is cut off by the roller 413. The rear guide rod 53 and the male mold 54 sleeved on the guide rod 53 approach the female mold under the action of the screw rod assembly and are driven by the cylinder and the motor fixed on the positioning seat 52 to push the male mold 54 to complete the folding process of the shielding layer.

[0046] Figure 8 The schematic diagram shows the overall structure of the wire clamp unit, combined with Figure 8The wire supporting jaw unit 2 is described in detail. The wire supporting jaw unit 2 includes a wire supporting jaw, a first driving component for driving the wire supporting jaw to open and close, and a second driving component for driving the wire supporting jaw to move forward and backward; the wire supporting jaw is composed of a left wire supporting jaw 21 and a right wire supporting jaw 22, and the opening and closing of the wire supporting jaw is adjusted by regulating the approach or distance between the left wire supporting jaw 21 and the right wire supporting jaw 22. Specifically, by fixing the left wire supporting jaw 21 and the right wire supporting jaw 22 on a movable seat 23 that can reciprocate laterally, in order to facilitate the lateral reciprocating movement of the aforementioned movable seat 23, a slide rail can be arranged laterally, and the aforementioned movable seat 23 and the slide rail are arranged on a fixed plate 25. The first driving assembly includes a screw driven by a motor and a movable block 24 that cooperates with the screw thread. In some embodiments, the movable block 24 is directly fixedly connected to the movable seat 23, and the movable block 24 that is fixed as a whole with the left wire clamping jaw 21 and the movable block 24 that is fixed as a whole with the right wire clamping jaw 22 are in opposite thread directions, so that when the screw rotates, the left wire clamping jaw 21 and the right wire clamping jaw 22 can be directly driven to approach or move away; in other embodiments, a movable block 24 that cooperates with the screw thread is connected to the left wire clamping jaw 21 or the right wire clamping jaw 22. The movable seat 23 of any one of the wire supporting jaws 22 is fixed as a whole, and a first rack is fixedly arranged on the movable seat 23. A gear is movably fixed on the fixed plate 25, and the gear is meshed with the first rack. A second rack is also fixed on the movable seat 23 where the other of the left wire supporting jaw 21 or the right wire supporting jaw 22 is fixed, and the second rack is also meshed with the gear. The first rack and the second rack are symmetrical based on the center of the gear. Therefore, when the screw moves, the left wire supporting jaw 21 and the right wire supporting jaw 22 can be regulated to approach or move away from each other through the meshing of the gear and the first rack and the second rack.

[0047] A slide rail is fixedly arranged below the aforementioned fixed plate 25 along the length direction of the workbench 1, and the fixed plate 25 is driven by the second driving assembly to reciprocate along the length direction of the aforementioned slide rail, thereby adjusting the position of the wire support clamping unit 2 on the workbench 1, thereby adjusting the distance between the wire harness clamped by the wire support clamping unit 2 and the cutter disc cutting unit 4. Specifically, the second driving assembly includes a screw driven by a motor, and a connecting rod assembly is arranged on the screw rod, and the connecting rod assembly is fixed to the fixed plate 25. The motor drives the screw rod to rotate, driving the connecting rod assembly to move along the axial direction of the screw rod, thereby completing the position adjustment of the fixed plate 25 on the slide rail.

[0048] In some embodiments, a shielding layer brush unit 6 is also included. Fig. 9 The overall structure of the shielding layer brush unit is shown schematically. Fig. 9As shown, the shielding layer brush unit 6 includes at least two groups of brush assemblies 61 arranged in parallel. The brush assembly 61 is fixedly arranged on the adjustment assembly 62. The position of the brush assembly 61 is adjusted by the adjustment assembly 62, so as to straighten the new energy wiring harness. The brush assembly 61 is driven by a motor. The aforementioned adjustment assembly 62 includes a slide rail and a cylinder arranged vertically based on the die substrate 31. A wheel is fixedly arranged based on the aforementioned slide rail. Teeth are arranged on the aforementioned wheel rim and a groove adapted to its shape is opened on the wheel. The brush assembly 61 can move in the groove. A gear meshing with the gear is arranged on the aforementioned wheel rim. The gear is driven by a motor fixed on the brush assembly 61. The motor located on the brush assembly 61 drives it to move along the wheel, so as to adjust the position of the brush assembly 61.

[0049] The aforementioned shielding layer brush unit 6 is activated after the shielding layer of the wire harness is cut off. After the shielding layer of the wire harness is cut off, the wire harness is withdrawn to the position of the shielding layer brush unit by the wire supporting jaw unit 2, and then the shielding layer is brushed straight by the shielding layer brush unit 6. After brushing straight, the wire supporting jaw unit 2 sends it into the cutter disc cutting unit 4 again for secondary cutting of the shielding layer to obtain a smoother shielding layer incision; then the punch assembly 5 and the die assembly 6 cooperate to complete the folding of the shielding layer after the secondary cutting.

[0050] A wire-holding clamp for grabbing the front section of the wire harness can also be fixedly provided on the aforementioned die substrate 31 to ensure that the wire harness extending into the cutter disc cutting unit 4 is in a straight line state, so as to prevent the wire harness from falling due to its own weight, thereby affecting the processing quality of the wire harness. A supporting claw that can move upward can be added between the die assembly 3 and the wire-holding clamp unit 2 to further ensure the linearity of the wire harness.

[0051] In actual application, the wire harness is placed in the wire supporting clamping jaws. After the wire supporting clamping jaws are closed, the wire harness is clamped and moved to the cutter disc cutting unit 4. Under the action of the cutter disc cutting unit 4, the cutting knife 412 and the clamping jaw unit are close to the wire harness, and the cutting knife 412 cuts off the front section of the outer insulation layer of the wire harness, and the clamping jaw unit grasps the front section. At this time, the wire supporting clamping jaw unit 2 drives the wire harness to exit for the first time and completes the stripping of the outer insulation layer and the aluminum foil layer of the wire harness; then the die moves downward to the specified position, and the punch assembly 5 also moves to the specified position under the action of the cylinder and the motor. At this time, the wire harness enters the cutter disc cutting unit 4 again driven by the wire supporting clamping jaw unit 2, and the cutter disc Under the action of the cutting unit 4, the roller 413 is close to the shielding layer to complete the partial cutting of the shielding layer, and makes the shielding layer explode at the broken part, and then the punch 54 moves close to the die and rotates to fold the shielding layer, and then the wire harness is driven by the wire supporting clamp unit 2 to exit for the second time to complete the folding of the shielding layer of the wire harness; then the wire supporting clamp unit 2 finally drives the wire harness to move into the cutter disc cutting unit 4, and completes the stripping process as the first entry to complete the stripping of the insulation layer inside the wire harness, and then the wire supporting clamp unit 2 drives the wire harness back to the initial position to complete the stripping, cutting and folding process of the wire harness, and then the shielding layer brush unit 6 can be used to complete the straightening process.

[0052] As an extended application mode, the wire-supporting clamp unit 2, the blade cutting unit 4, the shielding layer brush unit 6, the die assembly 3 and the punch assembly 5 involved in the utility model are combined to perform at least one of the processing techniques of outer insulation layer cutting, aluminum foil layer cutting, shielding layer cutting, shielding layer straightening, secondary cutting and inner insulation layer cutting, so as to adapt to the single-layer or multi-layer processing process of different types of coaxial cable harnesses; for example, when only the outer insulation layer of the coaxial cable harness needs to be stripped, only the wire-supporting clamp unit 2 and the blade cutting unit 4 are provided; and if only the shielding layer needs to be partially stripped and folded, the wire-supporting clamp unit 2, the blade cutting unit 4, the die assembly 3 and the punch assembly 5 are provided. If the shielding layer needs to be straightened, a shielding layer brush unit 6 is added.
