Description

Technical Field

[0001] This invention relates to the field of wire harness stripping technology, and more particularly to a stripping device for wire harness processing. Background Technology

[0002] In the production and assembly of electronic equipment and electrical systems, in order to effectively connect wire harnesses and terminals, it is necessary to remove the outer sheath of the cable ends to expose the internal conductors before crimping, welding and other connection operations can be performed.

[0003] The common wire harness structure currently is such that each individual copper core conductor is covered with an inner insulation layer, and multiple such inner insulated cores are then bundled together and wrapped with a common outer sheath. For this type of multi-layered insulation wire harness, existing stripping processes and equipment mostly employ a step-by-step processing method: first, the outer sheath at the end of the wire harness is circumferentially cut and peeled off to expose the multiple individual inner insulated cores; then, the ends of each inner insulated core are stripped a second time to finally expose the copper core. This process usually involves multiple steps or requires operators to switch between different machines, which is not only cumbersome and inefficient, but also places high demands on processing accuracy and consistency. Furthermore, step-by-step processing is prone to core damage or length errors due to repeated clamping and positioning, affecting the final product quality. Summary of the Invention

[0004] To address the aforementioned deficiencies in the existing technology, this invention provides a stripping device for processing multi-layer insulated wire harnesses, which can adapt to multi-layer insulated wire harness structures and achieve efficient integrated end stripping, thereby simplifying operation steps and improving processing accuracy and production efficiency.

[0008] Furthermore, the rotating unit includes: a first gear ring, fixedly connected to the rotating seat; and a first gear, rotatably connected to the mounting base and meshing with the first gear ring. The first gear is driven to rotate, and its start and stop are controlled by the control panel.

[0009] Furthermore, the device also includes: a movable plate, slidably connected to the working surface, providing a movable supporting surface; and a first return spring, fixedly connected between the working surface and the movable plate, for resetting the movable plate.

[0010] Furthermore, the conveying unit includes: two sets of first rotating wheels, rotatably connected to the mounting frame and the loading platform respectively, wherein each set contains two first rotating wheels; two first conveyor belts, respectively wound around the two first rotating wheels in each set, the two first conveyor belts being arranged in parallel to form a conveying surface for clamping the end of the wire harness; two meshing synchronous gears, respectively fixedly connected to the shaft of one of the first rotating wheels in each set, and one of the synchronous gears being driven to rotate, and the rotation being started and stopped by the control panel; two second rotating wheels, rotatably connected to the loading platform, one of the second rotating wheels being coaxially fixed with one of the first rotating wheels; and a second conveyor belt, wound between the two second rotating wheels, for assisting in the transport of the wire harness.

[0011] Furthermore, the device also includes: a fixed frame, fixedly connected inside the processing frame and located directly above the working surface; an electric push rod, slidably connected to the fixed frame and capable of horizontal displacement along the fixed frame, electrically connected to the control panel for starting and stopping; a connecting frame, fixedly connected to the end of the telescopic rod of the electric push rod and controlled vertically by the electric push rod; a pressing plate, slidably connected to the bottom of the connecting frame for pressing the core of the wire harness; a second return spring, fixedly connected between the connecting frame and the pressing plate; a reciprocating screw, located on the fixed frame, having two layers, with the two layers of reciprocating screws respectively engaging with the upper and lower threads of the electric push rod housing, one of which is driven to rotate, controlled by the control panel for starting and stopping rotation; and a second transmission component, located between the reciprocating screws for synchronously transmitting rotational power.

[0012] Furthermore, the device also includes: at least three sets of labeling tapes, which are fixedly connected to the second conveyor belt at fixed intervals along the conveying direction, and the wire harness is fed at fixed points using the labeling tapes; an identifier, which integrates a vision recognition module, is fixedly connected to the mounting frame and faces the running path of the second conveyor belt, and the identifier is electrically connected to the control panel, and its signal is used to control the start and stop of the conveying unit.

[0013] The present invention has the following advantages: By integrating the ring cutting unit and the flat cutting unit into a rotatable and switchable mounting plate, and with the precise advance and retreat of the electric seat, the present invention realizes the sequential and automated stripping of multi-layer insulated wire harnesses from the outer sheath to the inner conductor sheath; by integrating the traditional step-by-step, multi-process processing flow into a continuous automated cycle, the present invention can effectively solve the problems of fragmented process flow, cumbersome operation, low efficiency and easy damage to the conductor core by multiple clamping in the existing technology, and significantly improve the efficiency, accuracy and consistency of stripping operations.

[0014] By using the ring-cutting unit, this invention not only improves the efficiency of stripping the outer sheath of multi-layer wire harnesses, but also ensures the flatness and consistency of the ring-cut, effectively preventing damage to the internal conductor core, thereby improving the overall quality and reliability of wire harness end processing; by using the flat-cutting unit, this invention can achieve uniform removal of the conductor core sheath, with flat cuts and consistent lengths, thereby improving the overall quality and consistency of wire harness end processing.

[0015] By using a movable plate to provide a stable supporting surface for the wire harness end, the wire harness end is prevented from bending downwards, ensuring the alignment accuracy of subsequent wire harness stripping operations; and the movable plate can extend and retract freely, allowing the wire harness end to smoothly enter the ring cut and flat cut, avoiding interference with the wire harness.

[0016] The conveying unit not only enables stable transport of the wire harness, but also strictly limits the axial movement and circumferential rotation of the wire harness during transport, laying the foundation for precise positioning and stripping of its ends. The second conveyor belt operates synchronously with the first conveyor belt, providing auxiliary support and transport for the main body of the wire harness to avoid dragging, twisting or deviation that may be caused by uneven weight, length or friction of the wire harness, ensuring the smoothness and integrity of the entire wire harness movement within the transport channel.

[0017] This invention arranges the conductor bundles neatly, enabling the two flat cutting blades of the flat cutting unit to simultaneously and precisely apply force to the insulation of each conductor, ensuring consistent and complete cutting depth. It is particularly suitable for complex wire harnesses with a large number of conductors and small diameters, thereby enhancing the adaptability of this invention to wire harnesses of different specifications and the consistency of processing results.

[0018] By combining the labeling tape with the identifier, this invention will achieve fully automated connection of the entire process from "aligning the loading reference" to "precise docking at the processing position" and then to "automatic triggering of the processing program". This can greatly improve the consistency of loading and enhance the overall operation cycle and automation level of this invention, ensuring the continuity, efficiency and reliability of the production process.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] Example: A stripping device for wire harness processing, see reference. Figures 1-2The device includes: a processing frame 11, which serves as the main mounting structure of the device; a loading platform 12, which is fixedly installed on the front side of the processing frame 11 and serves as the loading area for the wire harness 01; a control panel 13, which is fixedly installed on the left side of the processing frame 11 and integrates a control system for overall control of the device's operation; a mounting frame 14, which is fixedly installed on the front side of the processing frame 11 and forms a conveying channel 15 between it and the top rear part of the loading platform 12, for constraining and guiding the wire harness 01 through. The middle of the conveying channel 15 provides a working surface 1501, where the wire harness 01 undergoes stripping processing; and a conveying unit 16, which is located between the mounting frame 14 and the loading platform 12 and is used to clamp and convey the wire harness 01 in the conveying channel 15.

[0031] See Figures 2-4 The device also includes: a support frame 21, fixedly installed inside the rear side of the processing frame 11, located directly behind the working surface 1501; an electric base 22, fixedly installed on the support frame 21, electrically connected to and controlled by the control panel 13; a mounting base 23, fixedly installed on the control end of the electric base 22, driven by the electric base 22 to perform linear displacement in the forward and backward direction; a rotating base 24, rotatably installed outside the mounting base 23; and a rotating unit 25, disposed between the rotating base 24 and the mounting base 23. Between 3, it is used to drive the rotating seat 24 to rotate around its axis; the mounting plate 26 is fixedly installed on the front side of the rotating seat 24, and its plate surface is provided with a ring cut 2601 and a flat cut 2602; the ring cutting unit 27 is provided on the mounting plate 26 and located in the ring cut 2601, and is used to perform ring cutting on the outer sheath of the wire harness 01; the flat cutting unit 28 is provided on the mounting plate 26 and located in the flat cut 2602, and is used to cut the sheath of each conductor inside the wire harness 01.

[0032] See Figure 4 The rotating unit 25 includes: a first gear ring 2501, which is fixedly installed on the rotating seat 24; and a first gear 2502, which is rotatably installed in the mounting seat 23 and meshes with the first gear ring 2501. The first gear 2502 is independently driven to rotate by a motor, and its start and stop are controlled by the control panel 13, thereby driving the rotating seat 24 and the mounting plate 26 to perform precise angle switching.

[0033] First, the wire harness 01 is placed on the loading platform 12, and the conveying unit 16 clamps and transports the wire harness 01 to the working surface 1501. Then, the electric seat 22 drives the mounting seat 23 to extend forward, so that the end of the wire harness 01 enters the ring cut 2601 of the mounting plate 26. The control panel 13 starts the ring cutting unit 27 to complete the ring cut on the total outer sheath of the wire harness 01. Next, the electric seat 22 retracts the mounting seat 23 backward, and uses axial displacement to peel the ring-cut total outer sheath from the wire harness 01, exposing multiple independent guide cores inside.

[0034] After the overall outer sheath is stripped, the rotating unit 25 is activated, driving the first gear 2502 to rotate, which in turn drives the rotating seat 24 and the mounting plate 26 to rotate, precisely aligning the flat cut 2602 with the wire harness 01 on the working surface 1501. Then, the electric seat 22 extends the mounting plate 26 forward again, allowing the exposed core portion to enter the flat cut 2602. The control panel 13 activates the flat cutting unit 28 to cut the sheaths on each core. Finally, the electric seat 22 retracts again to peel off the cut core sheaths, thus completing the efficient and sequential stripping of different layers of sheaths at the end of the wire harness 01.

[0035] This device integrates a ring-cutting unit 27 and a flat-cutting unit 28 onto a rotatable and switchable mounting plate 26, and, in conjunction with the precise advance and retreat of the electric seat 22, achieves sequential and automated stripping of the multi-layer insulated wire harness 01 from the outer sheath to the inner conductor sheath. By integrating the traditional step-by-step, multi-process processing flow into a continuous automated cycle, this device can effectively solve the problems of fragmented process flow, cumbersome operation, low efficiency, and damage to the conductor core caused by repeated clamping in existing technologies, significantly improving the efficiency, accuracy, and consistency of stripping operations.

[0036] See Figure 5 The circumferential cutting unit 27 includes: a mounting ring 2701, rotatably mounted in the circumferential cutting opening 2601; three oblique cutting blades 2702, rotatably mounted on the mounting ring 2701, evenly distributed along the circumference of the mounting ring 2701, one of which is independently driven by a motor, and its rotation start and stop are controlled by the control panel 13; a second gear 2703, fixedly mounted on the rotating shaft of each oblique cutting blade 2702; a second gear ring 2704, rotatably mounted inside the mounting ring 2701 and meshing with all the second gears 2703; a third gear ring 2705, fixedly mounted on the outer circumference of the mounting ring 2701; and a third gear 2706, rotatably mounted inside the mounting plate 26 and meshing with the third gear ring 2705, which is also independently driven by a motor, and its rotation start and stop are also controlled by the control panel 13.

[0037] When the end of the wire harness 01 extends into the ring cut 2601, the ring cutting unit 27 is activated. The control panel 13 controls the rotation of the oblique cutting blade 2702. With the transmission of the second gear 2703 and the second gear ring 2704, all oblique cutting blades 2702 are driven to synchronously retract towards the center, and their blade tips are gradually pressed into the total outer sheath of the wire harness 01. Subsequently, the control panel 13 controls the rotation of the third gear 2706. Through the third gear ring 2705 meshing with it, the entire mounting ring 2701 and all the oblique cutting blades 2702 mounted on it are driven to rotate together around the axis of the wire harness 01. The rotating oblique cutting blades 2702 can complete the ring cut on the total outer sheath of the wire harness 01. After the cutting is completed, the electric seat 22 drives the mounting seat 23 to move backward. The mounting seat 23 drives the ring cutting unit 27 on it to retract as a whole. Then the oblique cutting blade 2702 that has cut into the outer sheath can peel off the cut outer sheath segment from the wire harness 01, thereby completing the removal of the outermost total outer sheath of the wire harness 01.

[0038] Through the ring-cutting unit 27, this device can not only improve the efficiency of stripping the outer sheath of the multi-layer wire harness 01, but also ensure the flatness and consistency of the ring cut, effectively preventing damage to the internal conductor core, so as to improve the overall quality and reliability of the wire harness 01 end processing.

[0039] See Figure 5 The flat cutting unit 28 includes: two sets of parallel movable frames 2801, two of which are slidably installed in the flat cutting opening 2602 and displaced along the length direction of the flat cutting opening 2602; flat cutting blades 2802, which are fixedly installed on each set of movable frames 2801, with the blades of the two flat cutting blades 2802 facing each other; two bidirectional screws 2803, which are rotatably installed on both sides of the flat cutting opening 2602, each of the two ends of the bidirectional screw 2803 is provided with threads of opposite directions, and respectively engage with the threaded ends of the corresponding sides of the two sets of movable frames 2801, one of the bidirectional screws 2803 is independently driven to rotate by a motor, and the rotation is started and stopped by the control panel 13; a first transmission component 2804 is disposed between the two bidirectional screws 2803, which includes transmission wheels fixed on the two bidirectional screws 2803 respectively and a transmission belt wound between the two transmission wheels.

[0040] Once the end of the wire harness 01 with its outer sheath removed has entered the flat cut 2602, the control panel 13 drives the bidirectional screw 2803 to rotate. Through the synchronous action of the first transmission component 2804, the two bidirectional screws 2803 rotate synchronously in the same direction. Through the reverse threads at both ends, the two sets of moving frames 2801 then drive the flat cutting blades 2802 on them to move towards the wire harness 01 until their blades cut into the exposed sheath of the conductor core and then stop moving. After the cutting is completed, the electric base 22 drives the mounting base 23 to retract as a whole according to the program, so that the cut sheath segment can be neatly peeled off from the conductor core.

[0041] Through the flat cutting unit 28, this device can achieve uniform removal of the conductor core skin layer, with flat cuts and consistent lengths, thereby improving the overall quality and consistency of the wire harness 01 end processing.

[0042] See Figure 6 and Figure 8 The device also includes: a movable plate 17, which is slidably installed on the working surface 1501 to provide a movable support surface; and a first return spring 18, which is fixedly installed between the working surface 1501 and the movable plate 17 to reset the movable plate 17.

[0043] During the non-processing or loading positioning stage, under the elastic force of the first return spring 18, the movable plate 17 is in the rear position, which can provide a stable supporting plane for the end of the wire harness 01, preventing the end of the wire harness 01 from bending downward and ensuring the alignment accuracy of the subsequent stripping operation of the wire harness 01. When the electric seat 22 drives the mounting plate 26 to move forward, preparing to perform the stripping operation on the wire harness 01, the mounting plate 26 will contact and push the movable plate 17 to slide forward, and the first return spring 18 will be compressed, so that the end of the wire harness 01 can smoothly extend into the ring cut 2601 and the flat cut 2602. When a single stripping operation is completed, the electric seat 22 drives the mounting plate 26 to return to its rear position and retract, and the compressed first return spring 18 restores the movable plate 17 to restore the supporting function for the end of the wire harness 01, preparing for the next operation.

[0044] See Figure 1 and Figure 9 The conveying unit 16 includes: two sets of first rotating wheels 1601, which are rotatably mounted inside the mounting frame 14 and on the top rear side of the loading platform 12, respectively. Each set includes two first rotating wheels 1601, and the first rotating wheel 1601 set of the loading platform 12 is located directly below the first rotating wheel 1601 set inside the mounting frame 14; two first conveyor belts 1602, which are respectively wound around the two first rotating wheels 1601 of each set. The two first conveyor belts 1602 are arranged in parallel and together form the conveying surface for clamping the end of the wire harness 01; two intermeshing... Synchronous gears 1603 are fixedly installed on the shafts of one of the first rotating wheels 1601 in each group, and one of the synchronous gears 1603 is driven to rotate independently by a motor and controlled to start and stop rotation by the control panel 13; two second rotating wheels 1604 are rotatably installed on the top front side of the loading platform 12, and one of the second rotating wheels 1604 is coaxially fixed with one of the first rotating wheels 1601 on the loading platform 12; a second conveyor belt 1605 is wound between the two second rotating wheels 1604 to assist in the transport of the wire harness 01.

[0045] The end of the wire harness 01 is placed between two first conveyor belts 1602. The control panel 13 drives the first rotating wheel 1601 to rotate. Power is transmitted to the upper and lower sets of first rotating wheels 1601 through the synchronous gear 1603. The two first rotating wheels rotate in opposite directions. Therefore, the two second conveyor belts 1605 can move in the same direction when they are close to each other. Under the action of this structure, the wire harness 01 is reliably clamped by the two first conveyor belts 1602 through friction and transported in a directional manner. This structure not only realizes the stable transport of the wire harness 01, but also strictly limits the axial movement and circumferential rotation of the wire harness 01 that may occur during the transport process, laying the foundation for the subsequent precise positioning and stripping of its end. At the same time, the second rotating wheel 1604, which rotates synchronously with the first rotating wheel 1601, drives the second conveyor belt 1605 to run synchronously, providing auxiliary support and transport for the main body of the wire harness 01, so as to avoid dragging, twisting or deviation that may be caused by the weight, length or uneven friction of the wire harness 01, and ensure the smoothness and integrity of the entire wire harness 01 in the transport channel 15.

[0046] After the conveying unit 16 accurately delivers the end of the wire harness 01 to the working surface 1501, the first conveyor belt 1602 and the second conveyor belt 1605 simultaneously stop running, keeping the wire harness 01 stationary during processing to ensure the positional accuracy of the stripping operation; until the stripping operation is completed, the conveying unit 16 restarts and continues to convey the processed wire harness 01 forward until it is discharged from the end of the conveying channel 15, and then prepares for the next work cycle.

[0047] The conveying unit 16 enables precise positioning and conveying of the end of the wire harness 01, providing effective assurance for the positioning of the wire harness 01, thereby improving the consistency of the stripping quality and the reliability of the processing flow of this device.

[0048] See Figure 2 , Figure 6 and Figure 7The device also includes: a fixed frame 31, fixedly installed inside the processing frame 11, located directly above the working surface 1501; an electric push rod 32, slidably installed on the fixed frame 31, capable of moving left and right along the fixed frame 31, electrically connected to the control panel 13 for starting and stopping; a connecting frame 33, fixedly installed at the end of the telescopic rod of the electric push rod 32, controlled vertically by the electric push rod 32; a pressing plate 34, slidably installed at the bottom of the connecting frame 33, used to press the guide core of the wire harness 01; a second return spring 35, fixedly installed between the connecting frame 33 and the pressing plate 34; and a reciprocating screw 36, located on the fixed frame 31. The frame 31 has two layers, upper and lower, with two reciprocating screws 36 arranged in parallel on each layer. The two layers of reciprocating screws 36 are respectively threaded with the upper and lower sides of the housing of the electric push rod 32. One of the reciprocating screws 36 is driven by a motor, and the rotation is controlled by the control panel 13. The second transmission component 37 is located between each reciprocating screw 36. Specifically, a set of second transmission components 37 is provided between the two reciprocating screws 36 in each layer and between one reciprocating screw 36 in each of the upper and lower layers. It includes a transmission wheel fixed on the two reciprocating screws 36 and a transmission belt wound between the two transmission wheels.

[0049] Before the outer sheath of wire harness 01 is completely peeled off and the inner guide core sheath is about to be cut, the control panel 13 controls the telescopic rod of the electric push rod 32 to extend downward, driving the connecting frame 33 and the pressing plate 34 to descend until the bottom surface of the pressing plate 34 contacts the guide core. The second return spring 35 is compressed, allowing the pressing plate 34 to flexibly press the guide core and avoid rigid damage. Subsequently, the control panel 13 drives the reciprocating screw 36 to rotate, driving the electric push rod 32 and the pressing plate 34 at its lower end to move back and forth. During this process, the pressing plate 34, under the continuous pressure of the second return spring 35, reciprocates to "comb" the multiple guide cores below, arranging all the guide cores neatly and constraining them to the same horizontal plane. After the arrangement is completed, the electric push rod 32 drives the pressing plate 34 to move upward and reset, and the second return spring 35 naturally returns to its original position.

[0050] The neatly arranged conductor bundles allow the two flat cutting blades 2802 of the flat cutting unit 28 to simultaneously and precisely apply their cutting blades to the insulation of each conductor, ensuring consistent and complete cutting depth. This is especially suitable for complex wire harnesses 01 with a large number of conductors and small diameters, thereby enhancing the adaptability of the device to wire harnesses 01 of different specifications and the consistency of the processing effect.

[0051] See Figure 1The device also includes: at least three sets of labeling tapes 41, which are fixedly installed on the second conveyor belt 1605 at fixed intervals along the conveying direction, and the wire harness 01 is fed at fixed points using the labeling tapes 41; and an identifier 42, which integrates a vision recognition module, is fixedly installed on the mounting frame 14 and faces the running path of the second conveyor belt 1605. The identifier 42 is electrically connected to the control panel 13, and its signal is used to control the start and stop of the conveying unit 16.

[0052] After the operator completes the loading based on the labeling tape 41, the second conveyor belt 1605 carries the wire harness 01 and the labeling tape 41 fixed on it and moves together toward the working surface 1501. When the wire harness 01 is transported to the working surface 1501 area, the labeling tape 41 that accompanies it enters the effective detection range of the identifier 42. After the identifier 42 detects the signal of the labeling tape 41, the control panel 13 immediately issues a control command. First, it shuts down the conveyor unit 16, so that the first conveyor belt 1602 and the second conveyor belt 1605 stop accurately, ensuring that the wire harness 01 is stationary on the working surface 1501. Then, it controls the ring cutting unit 27 and the flat cutting unit 28 to perform the corresponding peeling operations in sequence.

[0053] With the cooperation of the labeling tape 41 and the identifier 42, this device will realize the fully automated connection of the entire process from "aligning the feeding reference" to "precisely stopping at the processing position" and then to "automatic triggering of the processing program". This can greatly improve the consistency of feeding and enhance the overall operating cycle and automation level of the device, ensuring the continuity, efficiency and reliability of the production process.

[0054] This device can also adapt to wire harnesses 01 of different sizes and specifications without the need for physical position replacement or overall structural adjustment. It only needs to control the central axis of the annular cut 2601 and the flat cut 2602 on the mounting plate 26 to accurately coincide with the actual central axis of the wire harness 01 of any size being transported to the working surface 1501. This coincidence is mainly achieved through the following two points: First, the rotation of the mounting plate 26 is stepless angle adjustment. Regardless of the size of the wire harness 01, as long as the mounting plate 26 is rotated to a suitable angle, the geometric center of the ring cut 2601 and the flat cut 2602 can be aligned with the center of the wire harness 01. Second, the working surface 1501 has a certain design width in the conveying direction, which provides a certain tolerance range for the actual stopping position of wire harnesses 01 of different sizes. Wire harnesses 01 of different sizes do not need to stop at an absolutely fixed "point", but can adaptively stop at the position corresponding to the center of the upper ring interface and the flat cut 2602 of the mounting plate 26.

[0055] Furthermore, although the stopping position of the wire harness 01 may vary within the width of the working surface 1501 due to its different size, the reference trigger position of the identifier 42 remains unchanged. However, by flexibly setting the delay parameter, the wire harness 01 of different sizes can be accurately delivered to its respective optimal working position that matches the cutting center of the mounting plate 26, providing distance compensation for position adjustment.

[0056] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
