SUMMARY

[0003] The present application provides a foolproof complex wiring harness and a binding method of the wiring harness, which can effectively reduce and inhibit the wiring harness mess and entanglement problem, and the sponge binding body 24 plays a role in buffering the impact of lateral collision and vibration.

[0004] Technical scheme: To achieve the above-mentioned purpose, the present application provides a foolproof complex wiring harness, which at least includes a wire harness end, a wire harness end, a wire harness end, a first single-wire harness and a second single-wire harness; one end of the first single-wire harness and the second single-wire harness is commonly connected to the wire harness end; the other end of the first single-wire harness and the second single-wire harness is respectively connected to the wire harness end and the wire harness end.

[0005] The first single-wire harness and the second single-wire harness are parallelly bound by the sponge binding body, and the bound part of the first single-wire harness and the second single-wire harness is respectively recorded as the first single-wire harness binding section and the second single-wire harness binding section, and the unbound part of the first single-wire harness and the second single-wire harness is recorded as the first single-wire harness free section and the second single-wire harness free section.

[0006] Further, the length of the first single-wire harness free section is greater than the length of the second single-wire harness free section.

[0007] Further, the cross section of the sponge binding body is in the shape of "S", and in the cross section view, the cross section of the "S" shaped sponge binding body is composed of a first circular arc part and a second circular arc part, and the connection part of the first circular arc part and the second circular arc part is clamped between the first single-wire harness binding section and the second single-wire harness binding section; the first circular arc part is wrapped and bonded on the outer surface of the first single-wire harness binding section, and the second circular arc part is included and bonded on the outer surface of the second single-wire harness binding section.

[0008] Further, the first card seat, the second card seat, the third card seat, the sponge belt storage roll, the cutting device, the first rolling unit, the second rolling unit, the clamp, the first folding rod, the second folding rod and the straight line glue brushing device are prepared.

[0009] Step one, the first card seat, the second card seat and the third card seat are respectively provided with a first card slot, a second card slot and a third card slot; the first card seat and the second card seat can respectively translate under the driving of the first linear displacement device and the second linear displacement device, and the third card seat is a fixed part;

[0010] The sponge belt storage roll leads the belt-shaped sponge in a rolled state to be drawn out along the X-direction, and the end upper part of the linear belt-shaped sponge drawn out along the X-direction is clamped by the clamp installed on the mechanical arm, and the mechanical arm can drive the clamp to move in the X-direction;

[0011] The cutting device cuts vertical upper and lower cutting seams on the linear belt-shaped sponge drawn out along the X-direction, and the linear belt-shaped sponge is not completely disconnected at the upper and lower cutting seams; the linear belt-shaped sponge between the upper and lower cutting seams and the clamp is recorded as a sponge belt to be bound segment,

[0012] Step two, the a wire bundle end, the b wire bundle end and the c wire bundle end of the wire bundle before binding are respectively clamped into the first card slot, the second card slot and the third card slot by using a mechanical hand or manual work; at this time, the first single wire bundle and the second single wire bundle are in a straight and tight state.

[0013] Step three, the first rolling unit and the second rolling unit are respectively on the side away from each other of the first single wire bundle and the second single wire bundle;

[0014] The first rolling unit comprises a first wire clamping groove wheel, and the first wire clamping groove wheel has a wire clamping ring groove on the outer periphery; the second rolling unit comprises a second wire clamping groove wheel, and the second wire clamping groove wheel has a wire clamping ring groove on the outer periphery;

[0015] The third linear displacement device and the fourth linear displacement device drive the first rolling unit and the second rolling unit to move towards each other along the Y-direction, the first wire clamping groove wheel and the second wire clamping groove wheel respectively bend the first single wire bundle and the second single wire bundle, and at the same time, the first card seat and the second card seat are adaptively translated under the driving of the first linear displacement device and the second linear displacement device, so that the first single wire bundle and the second single wire bundle always maintain a relatively tight state during the bending process;

[0016] Finally, the first single wire bundle is divided into a first single wire bundle binding segment and a first single wire bundle free segment by taking the first rolling unit as a boundary; the second single wire bundle is divided into a second single wire bundle binding segment and a second single wire bundle free segment by taking the second rolling unit as a boundary; at this time, the first single wire bundle binding segment and the second single wire bundle binding segment are exactly parallel, and the first single wire bundle free segment and the second single wire bundle free segment are in a V-shaped open state.

[0017] Step four, the sponge tape storage roll gradually leads the tape-shaped sponge in the roll state along the X-direction, while the gripper clamps the upper part of the sponge tape to be bound and displaces it along the X-direction, so that the whole sponge tape to be bound displaces along the X-direction, until the sponge tape to be bound first passes between the first rolling unit and the second rolling unit, the first rolling unit and the second rolling unit adaptively rotate, and then continue to displace along the X-direction, until the sponge tape to be bound is completely clamped between the first single wire bundle binding section and the second single wire bundle binding section;

[0018] Step five, further comprising a first folding rod and a second folding rod with a length consistent with the length of the sponge tape to be bound and parallel to the X-direction;

[0019] Further comprising a first Z-direction displacer and a first Y-direction displacer, under the combination of the first Z-direction displacer and the first Y-direction displacer, the first folding rod can make arbitrary YZ plane motion;

[0020] Further comprising a first Z-direction displacer and a first Y-direction displacer, under the combination of the first Z-direction displacer and the first Y-direction displacer, the first folding rod can make arbitrary YZ plane motion;

[0021] Further comprising a second Z-direction displacer and a second Y-direction displacer, under the combination of the second Z-direction displacer and the second Y-direction displacer, the second folding rod can make arbitrary YZ plane motion;

[0022] First, control the gripper to make a release action, and then control the first folding rod to displace to the lower side of the first single wire bundle binding section under the combination of the first Z-direction displacer and the first Y-direction displacer, and control the second folding rod to displace to the upper side of the second single wire bundle binding section under the combination of the second Z-direction displacer and the second Y-direction displacer;

[0023] Then, a straight-line glue applying device is used to apply a layer of a bonding agent a to the side of the upper part of the sponge tape to be bound away from the second folding rod, and a layer of a bonding agent b to the side of the lower part of the sponge tape to be bound away from the first folding rod;

[0024] Step six, control the first folding rod to push to the Y-direction under the combination of the first Z-direction displacer and the first Y-direction displacer, and then control the first folding rod to rotate clockwise around the axis of the second single wire bundle binding section, so that the lower part of the sponge tape to be bound is bent in a circular arc shape under the pushing of the first folding rod and is wrapped and bonded to the outer surface of the second single wire bundle binding section;

[0025] Under the combined control of the second Z-axis displacement device and the second Y-axis displacement device, the second folding rod is pushed in the Y+ direction to the section of the sponge tape to be bound. Then, the second folding rod is controlled to rotate counterclockwise around the axis of the first single wire harness binding section. This causes the upper part of the section of the sponge tape to be bound to bend in an arc shape under the pressure of the second folding rod and wrap around and adhere to the outer surface of the first single wire harness binding section. At this time, the section of the sponge tape to be bound becomes a sponge binding body. The wire harness binding is now complete. At this time, the newly formed sponge binding body may not be completely separated from the end of the straight strip of sponge.

[0026] Step 7: Control the clamp to move until it clamps the upper part of the end of the straight strip of sponge extending along the X- direction. Then, control the clamp to pull the end of the straight strip of sponge in the X+ direction, thereby breaking the connection between the end of the straight strip of sponge and the newly formed sponge binding body. Finally, disassemble the bound wire bundle.

[0027] Beneficial effects: The "S"-shaped binding structure of this invention allows the first and second single-wire harness binding segments to be bound together while maintaining a certain barrier distance between them. This not only effectively reduces signal interference between them, but also prevents cross-current and leakage problems even if damaged by external factors due to the insulating sponge structure between the first and second single-wire harness binding segments. Furthermore, after binding, the sponge binding body is integrated with the first and second single-wire harness binding segments through adhesive bonding, eliminating the need for separate cable ties. Additionally, this binding method allows for a simple and efficient binding process for this special binding structure. Attached Figure Description

[0036] The application will be further described below with reference to the drawings.

[0037] As shown in the accompanying drawings Figures 1 to 8 A foolproof complex wire harness at least includes a wire harness end head 13, a wire harness end head 14, a wire harness end head 13, a first single wire harness 16 and a second single wire harness 23.

[0038] As shown in the upper drawing, before the wire harness is bound: one end of the first single wire harness 16 and the second single wire harness 23 is electrically connected to the wire harness end head 13; the other end of the first single wire harness 16 and the second single wire harness 23 is electrically connected to the wire harness end head 14 and the wire harness end head 13 respectively; before being bound, the first single wire harness 16 and the second single wire harness 23 are in a completely free state, which is easy to form a wire harness mess after being plugged in and entangled with other wire harnesses, and does not have an obvious foolproof function. Figure 1 As shown in the lower drawing, after the wire harness is bound: the part of the first single wire harness 16 and the second single wire harness 23 close to the wire harness end head 13 is bound in parallel by a sponge binding body 24, the bound part of the first single wire harness 16 and the second single wire harness 23 is respectively marked as the first single wire harness bound section 16b and the second single wire harness bound section 23b, and the unbound part of the first single wire harness 16 and the second single wire harness 23 is marked as the first single wire harness free section 16a and the second single wire harness free section 23a; after being bound, the whole wire harness presents a Y shape, and in the case of the wire harness used in the automobile field,

[0039] The mark 100 in the lower drawing can be bound to the vehicle frame, the wire harness end head 13, the wire harness end head 14 and the wire harness end head 13 are respectively overlapped on the corresponding interface position, the length of the first single wire harness free section 16a is greater than the length of the second single wire harness free section 23a, and the length of the first single wire harness free section 16a is greater than the length of the second single wire harness free section 23a to achieve the purpose of foolproof, because the length of the second single wire harness free section 23a is relatively short, it cannot be plugged into a more distant error interface, thereby achieving the purpose of foolproof. Figure 1 Figure 1 At the same time, the binding structure shortens the free section length, effectively inhibits the wire harness mess and entanglement problem; at the same time, the sponge binding body 24 plays a role in buffering the impact of lateral collision and vibration, thereby protecting the wire harness from external environmental interference.

[0040] The cross section of the sponge binding body 24 presents an "S" shape, as shown in the accompanying drawings

[0041] The cross section of the sponge binding body 24 presents an "S" shape, as shown in the accompanying drawings Figure 8 ​As shown, in the cross-sectional view, the cross-section of the "S"-shaped sponge binding body 24 is composed of a first circular arc portion 24a and a second circular arc portion 24b, and the connection between the first circular arc portion 24a and the second circular arc portion 24b is clamped between the first single-wire bundle binding section 16b and the second single-wire bundle binding section 23b; the first circular arc portion 24a is wrapped and bonded to the outer surface of the first single-wire bundle binding section 16b, and the second circular arc portion 24b includes and is bonded to the outer surface of the second single-wire bundle binding section 23b, and the bonding agent is a quick-drying epoxy resin; the "S"-shaped binding structure allows the first single-wire bundle binding section 16b and the second single-wire bundle binding section 23b to be bound together while maintaining a certain barrier distance between them, effectively reducing signal interference between them, and even if damaged by external factors, the isolation sponge structure between the first single-wire bundle binding section 16b and the second single-wire bundle binding section 23b prevents mutual cross-talk and leakage, and the sponge binding body 24 is already integrated with the first single-wire bundle binding section 16b and the second single-wire bundle binding section 23b as a unitary structure under the effect of the glue joint, eliminating the need for additional binding.

[0043] Step one, prepare the first card holder 17, the second card holder 18 and the third card holder 19; the first card holder 17, the second card holder 18 and the third card holder 19 are respectively provided with a first card slot 20, a second card slot 21 and a third card slot 22; the first card holder 17 and the second card holder 18 can be translated under the driving of the first linear displacement device 61 and the second linear displacement device 62 respectively, and the third card holder 19 is a fixed part;

[0044] It also includes a sponge tape storage roll and a cutting device 5 that can be actively rotated, the sponge tape storage roll leads the tape-shaped sponge 1 in a wound state in the X-direction, and the end upper part of the linear tape-shaped sponge 1 led in the X-direction is clamped by the clamp holder 3, the clamp holder 3 is installed on the mechanical arm 2, and the mechanical arm 2 can drive the clamp holder 3 to move in the X-direction;

[0045] The cutting device 5 cuts the linear tape-shaped sponge 1 led in the X-direction to form a vertical upper and lower cutting seam 4, and the linear tape-shaped sponge 1 at the upper and lower cutting seam 4 is not completely disconnected; the linear tape-shaped sponge 1 between the upper and lower cutting seam 4 and the clamp holder 3 is denoted as the sponge tape to be bound section 1a; at this time, as shown in the upper figure; Figure 2

[0046] ​Step two, use mechanical hand or manual to put the a wire harness end 13, b wire harness end 14, c wire harness end 13 of the wire harness before binding into the first card slot 20, second card slot 21 and third card slot 22 respectively; At this time, the first single wire harness 16 and the second single wire harness 23 are in a straight and tight state, and the first single wire harness 16 and the second single wire harness 23 form a V shape; At this time, as shown in the lower figure of Figure 2 ;

[0047] Step three, a first rolling unit 6 and a second rolling unit 7 are respectively arranged on the side away from each other of the first single wire harness 16 and the second single wire harness 23; The first rolling unit 6 and the second rolling unit 7 can be driven by the third linear displacement device 8 and the fourth linear displacement device 9 to move along the Y direction respectively;

[0048] As shown in Figure 5 , the first rolling unit 6 comprises a first vertical motor 30a, the output end of the upper end of the first vertical motor 30a is drivingly connected with a first lower rolling wheel 31a, a first upper rolling wheel 33a is coaxially and synchronously connected with the first lower rolling wheel 31a through a connecting column 34 above the first lower rolling wheel 31a, a first wire clamping groove wheel 32a is rotatably arranged outside the connecting column 34 between the first lower rolling wheel 31a and the first upper rolling wheel 33a through a bearing, and a wire clamping ring groove is arranged on the outer periphery of the first wire clamping groove wheel 32a;

[0049] The second rolling unit 7 comprises a second vertical motor 30b, the output end of the upper end of the second vertical motor 30b is drivingly connected with a second lower rolling wheel 31b, a second upper rolling wheel 33b is coaxially and synchronously connected with the second lower rolling wheel 31b through a connecting column 34 above the second lower rolling wheel 31b, a second wire clamping groove wheel 32b is rotatably arranged outside the connecting column 34 between the second lower rolling wheel 31b and the second upper rolling wheel 33b through a bearing, and a wire clamping ring groove is arranged on the outer periphery of the second wire clamping groove wheel 32b;

[0050] The third linear displacement device 8 and the fourth linear displacement device 9 drive the first rolling unit 6 and the second rolling unit 7 to move along the Y direction to approach each other until the first wire clamping groove wheel 32a on the first rolling unit 6 and the second wire clamping groove wheel 32b on the second rolling unit 7 clamp the side away from each other of the first single wire harness 16 and the second single wire harness 23 respectively;

[0051] The first rolling unit 6 and the second rolling unit 7 continue to move along the Y direction to approach each other, so that the first wire clamping groove wheel 32a and the second wire clamping groove wheel 32b respectively bend the first single wire harness 16 and the second single wire harness 23, and at the same time, the first clamping seat 17 and the second clamping seat 18 are adaptively translated under the driving of the first linear displacement device 61 and the second linear displacement device 62 respectively, so that the first single wire harness 16 and the second single wire harness 23 always maintain a relatively tight state during the bending process;

[0052] Finally, the first single wire bundle 16 is divided into a first single wire bundle binding section 16b and a first single wire bundle free section 16a by the first rolling unit 6; the second single wire bundle 23 is divided into a second single wire bundle binding section 23b and a second single wire bundle free section 23a by the second rolling unit 7; at this time, the first single wire bundle binding section 16b is just parallel to the second single wire bundle binding section 23b, and the first single wire bundle free section 16a and the second single wire bundle free section 23a are V-shapedly opened; as shown in the upper diagram of Figure 6 ;

[0053] Step four, the sponge tape storage roll gradually leads the tape-shaped sponge 1 in the rolled state out along the X-direction, at the same time, the gripper 3 clamps the upper part of the sponge tape to-be-bound section 1a and displaces it in the X-direction, so that the whole sponge tape to-be-bound section 1a displaces in the X-direction, until the sponge tape to-be-bound section 1a first passes between the first rolling unit 6 and the second rolling unit 7, the first rolling unit 6 and the second rolling unit 7 adaptively rotate forward, then continue to displace in the X-direction, until the sponge tape to-be-bound section 1a is completely clamped between the first single wire bundle binding section 16b and the second single wire bundle binding section 23b; as shown in the lower diagram of Figure 6 .

[0054] Step five, further comprising a first folding rod 10 and a second folding rod 11 with the same length as the sponge tape to-be-bound section 1a and parallel to the X-direction;

[0055] As shown in Figure 4 , further comprising a first Z-direction displacer 35a and a first Y-direction displacer 36a, under the combination of the first Z-direction displacer 35a and the first Y-direction displacer 36a, the first folding rod 10 can make arbitrary YZ plane motion;

[0056] Further comprising a first Z-direction displacer 35a and a first Y-direction displacer 36a, under the combination of the first Z-direction displacer 35a and the first Y-direction displacer 36a, the first folding rod 10 can make arbitrary YZ plane motion;

[0057] Further comprising a second Z-direction displacer 35b and a second Y-direction displacer 36b, under the combination of the second Z-direction displacer 35b and the second Y-direction displacer 36b, the second folding rod 11 can make arbitrary YZ plane motion;

[0058] First, control the gripper 3 to make a release action, then under the combination of the first Z-direction displacer 35a and the first Y-direction displacer 36a, control the first folding rod 10 to displace to the lower side of the first single wire bundle binding section 16b; under the combination of the second Z-direction displacer 35b and the second Y-direction displacer 36b, control the second folding rod 11 to displace to the upper side of the second single wire bundle binding section 23b;

[0059] Then, using a straight adhesive applicator, apply a layer of adhesive layer 51 (a) to the upper part of the section 1a to be bound, away from the second folding bar 11, and apply a layer of adhesive layer 51 (b) to the lower part of the section 1a to be bound, away from the first folding bar 10; Figure 7 ;

[0060] Step 6: Under the combined action of the first Z-axis displacement device 35a and the first Y-axis displacement device 36a, the first folding rod 10 is pushed in the Y-direction to the section 1a to be bound with the sponge tape. Then, the first folding rod 10 is rotated clockwise around the axis of the second single wire harness binding section 23b, so that the lower part of the section 1a to be bound with the sponge tape is bent in an arc shape under the push of the first folding rod 10 and wrapped and bonded to the outer surface of the second single wire harness binding section 23b.

[0061] Under the combined action of the second Z-axis displacement device 35b and the second Y-axis displacement device 36b, the second folding rod 11 is pushed in the Y+ direction to the section 1a to be bound with the sponge strip. Then, the second folding rod 11 is controlled to rotate counterclockwise around the axis of the first single-strand wire harness binding section 16b. This causes the upper part of the section 1b to be bound to bend in an arc shape under the pressure of the second folding rod 11 and wrap around and adhere to the outer surface of the first single-strand wire harness binding section 16b. At this point, the section 1a to be bound with the sponge strip becomes the sponge binding body 24, and the wire harness binding is complete. However, the newly formed sponge binding body 24 may not be completely separated from the end of the straight strip sponge 1. Figure 8 ;

[0062] Step 7: Control the clamp 3 to move to clamp the upper part of the end of the straight strip sponge 1 extending along the X- direction, and then control the clamp 3 to pull the end of the straight strip sponge 1 in the X+ direction, thereby breaking the connection between the end of the straight strip sponge 1 and the newly formed sponge binding body 24; finally, disassemble the bound wire bundle.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

Finally, the first single wire bundle (16) is divided into a first single wire bundle binding section (16b) and a first single wire bundle free section (16a) by the first rolling unit (6); the second single wire bundle (23) is divided into a second single wire bundle binding section (23b) and a second single wire bundle free section (23a) by the second rolling unit (7); at this time, the first single wire bundle binding section (16b) and the second single wire bundle binding section (23b) are just parallel, and the first single wire bundle free section (16a) and the second single wire bundle free section (23a) are V-shapedly opened; Step four, the sponge tape storage roll gradually leads out the tape-shaped sponge (1) in the rolled state along the X-direction, at the same time, the gripper (3) grips the upper part of the sponge tape to be bound (1a) and moves in the X-direction, so that the whole sponge tape to be bound (1a) moves in the X-direction, until the sponge tape to be bound (1a) first passes between the first rolling unit (6) and the second rolling unit (7), the first rolling unit (6) and the second rolling unit (7) adaptively rotate, and then continue to move in the X-direction, until the sponge tape to be bound (1a) is completely clamped between the first single wire bundle binding section (16b) and the second single wire bundle binding section (23b); Step five, including a first folding rod (10) and a second folding rod (11) with the same length as the length of the sponge tape to be bound (1a) and parallel to the X-direction; the first folding rod (10) and the second folding rod (11) can both move in the YZ plane; First, control the gripper (3) to perform a release action, then control the first folding rod (10) to move to the lower side of the first single wire bundle binding section (16b); control the second folding rod (11) to move to the upper side of the second single wire bundle binding section (23b); Then, a layer of a adhesive layer (51) is applied to the side of the upper part of the sponge tape to be bound (1a) away from the second folding rod (11), and a layer of b adhesive layer (51) is applied to the side of the lower part of the sponge tape to be bound (1a) away from the first folding rod (10); Step six, control the first folding rod (10) to push to the rear of the sponge tape to be bound (1a) in the Y-direction, then control the first folding rod (10) to rotate clockwise around the axis of the second single wire bundle binding section (23b), so that the lower part of the sponge tape to be bound (1a) is bent in a circular arc shape under the pushing of the first folding rod (10) and is wrapped and adhered to the outer surface of the second single wire bundle binding section (23b); Control the second folding rod (11) to push to the rear of the sponge tape to be bound (1a) in the Y+ direction, then control the second folding rod (11) to rotate counterclockwise around the axis of the first single wire bundle binding section (16b), so that the upper part of the sponge tape to be bound (1b) is bent in a circular arc shape under the pushing of the second folding rod (11) and is wrapped and adhered to the outer surface of the first single wire bundle binding section (16b); at this time, the sponge tape to be bound (1a) becomes a sponge binding body (24), and thus the wire bundle binding is completed, and at this time, the newly formed sponge binding body (24) and the end of the straight tape-shaped sponge (1) have not been completely disconnected; Step seven, control the pincers (3) to move to the upper end of the straight linear strip sponge (1) which is drawn along the X-direction, then control the pincers (3) to pull the end of the straight linear strip sponge (1) towards the X+ direction, so as to pull off the connection between the end of the straight linear strip sponge (1) and the newly formed sponge binding body (24); finally, the bound wire harness can be disassembled.

2. The method of claim 1, wherein: The length of the first single wire harness free section (16a) is greater than the length of the second single wire harness free section (23a).
