Description

Technical Field

[0001] The present invention relates to the technical field of wire harness assembly production, and in particular to a shielding layer breaking-up method and device based on wire harness composite motion. Background Art

[0002] In the manufacturing process of wire harnesses, the breaking up of the shielding layer is a key process to ensure the electrical performance of the wire harnesses. Traditional operation methods mainly rely on manual operation, and workers need to hold a pick needle or wire harness to manually break up the wires, which is not only inefficient, but also poses a safety hazard of being punctured by metal wires. Although existing semi-automatic equipment uses a breaking up module to replace manual labor, it still has significant defects: the scraping method using a hard pick needle will destroy the structural integrity of the shielding layer, making it difficult to form strands later; and the combing method using a single rotating brush is difficult to achieve a uniform breaking up effect due to the lack of multi-dimensional motion coordination. More prominently, the existing technologies have not considered the coordinated control of the dynamic movement of the wire harness and the action of the brush wire, resulting in the inability to achieve progressive and uniform dispersion of the metal wires in the shielding layer. In addition, the fixed processing mode cannot adapt to shielding layers of different wire diameters, and often causes problems of local excessive breaking up or insufficient breaking up. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a shielding layer debonding method and device based on the combined motion of the wire harness, which has the advantages of improving processing efficiency, ensuring operational safety, and enhancing the integrity of the shielding layer after processing.

[0004] In a first aspect, a shielding layer breaking-up method based on wire harness composite motion according to an embodiment of the present invention comprises the following steps: S1: Fix the ends of the wire harness and place the wire harness to be processed in the combing area; S2: driving at least one rotating tool with flexible brush filaments close to the shielding layer to be processed section, and causing the rotating tool to continuously rotate around its own axis; S3: While the rotary tool is rotating, the harness is controlled to perform a compound motion, wherein the compound motion is one of the following two modes or a combination thereof: a: Periodically swing up and down perpendicular to its length direction; b: Make the harness rotate periodically around its own axis; S4: During the execution of steps S2 and S3, the following progressive motions are synchronously controlled: a: The wire harness is progressively moved along its length toward a rotating tool with a flexible brush; S5: The metal wires of the shielding layer are combed and scattered by continuous contact, friction and progressive pressure between the flexible brush wires of the rotating tool and the shielding layer of the wire harness performing the composite motion.

[0005] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to the embodiment of the present invention, there are at least the following beneficial effects: the present application improves the breaking-up effect through the synergistic effect of multi-dimensional motion. The fixed end of the wire harness ensures the accurate positioning of the processing section and avoids the risk of manual handling; the flexible brush wire rotating tool is used to reduce the damage to the metal wire, and the self-rotation produces continuous friction; the composite motion design breaks through the limitation of single-direction processing, the up and down swing forms a longitudinal separation force, and the rotation around the axis produces a circumferential untwisting force, the superposition of the two can destroy the braided structure of the shielding layer; the progressive motion controls the contact pressure gradient, which not only ensures the flexible contact in the initial stage, but also realizes the progressive processing of deep breaking-up. Through the three elements of rotation, swinging and progressive coordination in a time sequence, the uniformity of metal wire separation is improved while reducing mechanical damage, forming a non-destructive and efficient breaking-up mechanism.

[0006] According to the shielding layer loosening method based on the composite motion of the wire harness according to an embodiment of the present invention, when fixing the end of the wire harness in step S1, an axial tensioning force is applied to the wire harness so that the shielding layer section to be processed is in a stretched and straightened state, and the tensioning direction is parallel to the length direction of the wire harness.

[0009] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to an embodiment of the present invention, at least two rotating tools with flexible brushes are used in step S2 to symmetrically clamp the shielding layer from both sides of the wire harness, and the two rotating tools rotate in opposite directions.

[0010] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to an embodiment of the present invention, the axes of the two rotating tools form an angle of 45° to 90° with the length direction of the wire harness, and the wire diameters of the brush filaments of the two rotating tools are different.

[0011] According to the shielding layer breaking-up method based on the combined motion of the wire harness according to an embodiment of the present invention, in step S3, the wire harness simultaneously performs up and down swinging and rotation around the axis, and the swinging and rotational motions are cooperatively controlled by independent servo motors.

[0012] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to an embodiment of the present invention, S4: during the execution of steps S2 and S3, one of the following progressive motions is synchronously controlled: a: The wire harness (1) is progressively moved along its length toward a rotating tool with a flexible brush; b: The rotating tool with flexible brush wire is moved gradually towards the shielding layer (11) of the wiring harness (1).

[0013] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to an embodiment of the present invention, the progressive motion (S4) and the composite motion (S3) are performed in one of the following time sequences: a: First perform a progressive motion to make the brush filament contact the shield layer, and then start the compound motion; b: progressive movement and compound movement are started simultaneously; c: Perform progressive movements in stages during compound movements.

[0016] According to the shielding layer breaking-up method based on the composite motion of the wire harness according to the embodiment of the present invention, in step S3, when executing mode A, the rotating tool is controlled to revolve circumferentially around the axis of the wire harness while rotating on its own.

Specifically, the first driving member in the breaking-up module drives the brush unit to rotate, replacing the manual operation to break up the shielding layer, and the shielding layer is mechanically broken up by the rotating brush, thereby improving the processing efficiency. In addition, the wire harness fixing module stably clamps the wire harness through the first clamping mechanism, while the swinging mechanism drives the wire harness to swing back and forth longitudinally, so that the brush unit can separate the shielding layer from the wire core while breaking up the shielding layer. On the one hand, it can avoid incomplete local processing of the shielding layer dispersion, and on the other hand, it can simulate manual swinging of the wire harness to separate the wire core from the shielding layer.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0028] Reference Figures 2 to 3 An embodiment of the present invention provides a device for breaking up the shielding layer of a wire harness 1, including a breaking up module 100 and a wire harness 1 fixing module.

[0029] Specifically, if Figures 2 to 3 As shown, the detangling module 100 includes a first driving member 110 and a combing unit 120 connected thereto, which is driven by the driving member to drive the combing unit 120 to rotate. The wiring harness 1 fixing module includes a first clamping mechanism 210 and a swinging mechanism. The first clamping mechanism 210 is used to fix the wiring harness 1, and the swinging mechanism drives the wiring harness 1 to move back and forth longitudinally.

[0030] It is understandable that after the wire harness 1 is fixed by the first clamping mechanism 210, the swing mechanism drives and drives the wire harness 1 to swing up and down in the longitudinal direction. At the same time, the first drive member 110 drives the combing unit 120 to rotate continuously, and the rotating brush contacts the surface of the shielding layer 11 of the wire harness 1. The longitudinal displacement of the wire harness 1 enables the brush to separate the wire core and the wire core from the shielding layer 11 when scraping and breaking up the shielding layer 11. At the same time, the longitudinal displacement of the wire harness 1 enables the brush to cover different areas of the shielding layer 11, and the rotating brush gradually breaks up the braided shielding layer 11 into independent metal wires through friction. In this process, mechanized clamping and swinging replace manual holding and moving actions, and the rotating brush replaces manual needle picking operations, forming a complete automated processing flow.

[0031] This application achieves continuous processing through mechanical transmission. The longitudinal swing of the wire harness 1 expands the coverage of a single treatment, and the continuous action of the rotating brush improves the detangling efficiency. At the same time, the rigid clamping of the first clamping mechanism 210 avoids positional deviation during manual gripping, ensuring uniform processing and achieving fully mechanized processing of the shielding layer 11 of the wire harness 1.

[0032] Specifically, the swing mechanism includes a third driving member 220 , the first clamping mechanism 210 is connected to the third driving member 220 , and the third driving member 220 can drive the first clamping mechanism 210 to move back and forth in the longitudinal direction.

[0033] As will be appreciated, upon receiving the control signal, the output shaft of the third drive member 220 drives the first clamping mechanism 210 to periodically reciprocate in the longitudinal direction according to a preset stroke and speed. During this process, the clamped wire harness 1 moves synchronously with the first clamping mechanism 210, simulating manual swinging of the wire harness 1. This solves the inefficiency and safety hazards associated with manual swinging of the wire harness 1, achieving fully automated control of the fixation and swinging of the wire harness 1. Furthermore, the programmed reciprocating motion parameters ensure the stability of the processing quality of the shielding layer 11.

[0034] Further, if Figure 1 As shown, two breaking-up modules 100 are arranged at intervals in the horizontal direction to achieve simultaneous processing of the sections to be processed at both ends of the wire harness 1, thereby effectively improving production efficiency.

[0035] This application provides a first embodiment of a combing unit 120. Specifically, combing unit 120 includes a brush connected to the output end of a first driving member 110, which drives the brush to rotate. It will be appreciated that when a single brush is used, the rotating brush directly contacts the shielding layer 11 of the wiring harness 1, and the high-speed rotation of the brush filaments 122 breaks up and separates the tangled wires.

[0036] Furthermore, when the length of the section to be processed is long, a brush with a larger diameter can be replaced; or, multiple brushes can be arranged side by side along the axial extension direction of the wire harness 1, and the section to be processed of the wire harness 1 contacts the brush to complete the process of breaking up the shielding layer 11.

[0037] like Figure 4 As shown, the present application provides a second embodiment of a combing unit 120. The combing unit 120 includes two brushes, arranged side by side. Two first drive members 110 are respectively connected to the two brushes, and the first drive members 110 drive the brushes to rotate. It can be understood that the two brushes form a group, forming a brush assembly to debond the shielding layer 11 of the processed section of the wire harness 1 from both sides. In the dual-brush structure, the two independently driven brushes are symmetrically arranged, allowing for simultaneous debonding of both sides of the wire harness 1, expanding the coverage area.

[0038] Furthermore, when the length of the section to be processed is long, the brush with a larger diameter can be replaced; or, Figure 5 As shown, multiple groups of brushes can be arranged side by side along the axial extension direction of the wire harness 1, which can adapt to various lengths of sections to be processed.

[0039] like Figures 2 to 3As shown, the present application provides a third embodiment of a combing unit 120. The combing unit 120 includes two brush assemblies arranged side by side. Two first drive members 110 are respectively connected to the two brushes. The brush assembly includes a transmission belt 121, a driving pulley 123, a driven pulley 124, and a brush filament 122 arranged on the surface of the transmission belt 121. The driving pulley 123 is connected to one end of the transmission belt 121, and the driven pulley 124 is connected to the other end of the transmission belt 121. The output end of the first drive member 110 is connected to the driving pulley 123. It can be understood that for the dual-brush assembly structure, the transmission belt 121 forms a closed-loop motion under the drive of the driving pulley 123. The flexible brush filaments 122 attached to the belt surface continuously sweep across the surface of the shielding layer 11, forming a uniform combing effect. Among them, the transmission belt brush assembly provided by the present application has a flexible contact method that is less likely to cause metal wire entanglement than traditional rigid brushes, reducing the probability of equipment jamming. While ensuring the detangling efficiency, the continuous circulation motion avoids metal wire residue and improves the consistency of the processing quality.

[0040] The three types of combing units 120 provided in this application all replace manual operation with mechanical transmission, avoiding direct contact between the operator and the metal wire, and the operator does not need to get close to the working area.

[0041] Furthermore, the present application also provides a first translation module 400 .

[0042] In some embodiments, the scattering module 100 is connected to the first translation module 400 so that during the scattering process, the scattering module 100 gradually moves and approaches the wire harness 1 fixing module to form a progressive motion.

[0043] Alternatively, in some other embodiments, the swing mechanism is connected to the first translation module 400 so that during the breaking up process, the swing mechanism gradually moves and approaches the wiring harness 1 fixing module to form a progressive motion.

[0044] Specifically, in the specific application of this application, such as Figure 2 and Figure 3 As shown, the first translation module 400 includes a first moving base 410 and a second driving member 420 . The scattering module 100 is installed on the first moving base 410 . The second driving member 420 can drive the first moving base 410 away from or close to the wire harness 1 .

[0045] The first movable base 410 serves as a supporting structure for the scattering module 100. The mounting base 320 of the scattering module 100 is connected to the first movable base 410. The first movable base 410 is slidably connected to the frame via a guide rail assembly. Optionally, the second driving member 420 may be a cylinder.

[0046] Alternatively, in some other embodiments, the second driving member 420 is a motor, and the first movable seat 410 is connected to the second driving member 420 via a screw transmission mechanism. The present application realizes automatic linear displacement control of the breaking up module 100 by providing a first translation module 400, which not only eliminates the manual intervention link, but also enables the combing unit 120 to dynamically adjust the contact depth according to the specifications of the wire harness 1, avoiding incomplete breaking up or excessive wear of the brush due to position deviation, solving the position adjustment problem between the breaking up module 100 and the wire harness 1, and realizing precise control of the contact depth between the combing unit 120 and the shielding layer 11. By replacing manual operation with an automated drive method, it ensures that the combing unit 120 is always in the optimal working position during the breaking up operation, and at the same time avoids motion interference between equipment during process conversion, thereby improving the degree of automation and production efficiency of the processing of the shielding layer 11 of the wire harness 1.

[0047] As a further improvement to the solution, a second translation module is provided, on which the brush assembly is mounted. The second translation module can drive the brush assembly toward or away from the shielding layer 11. Furthermore, the second translation module is provided with a pressure sensor to detect the pressure of the flexible brush filaments 122 on the shielding layer 11 in real time.

[0048] It can be understood that before the section to be processed of the wiring harness 1 is about to enter the working area, the second moving module, according to the system instructions, first drives the brush assembly to move to the preset position to wait for the section to be processed of the wiring harness 1. When the section to be processed enters the working area to break up and comb the shielding layer 11, the second moving module drives the brush assembly to continue to approach the section to be processed, so that the flexible brush filaments 122 gradually increase the contact pressure on the shielding layer 11. However, due to the differences in the shielding layers 11 of different wiring harnesses, that is, the weaving density of the shielding layer 11 is different. The pressure sensor monitors the contact pressure of the flexible brush filaments 122 on the shielding layer 11 in real time, and the second moving module determines whether the second moving module needs to drive the brush assembly closer to or away from the section to be processed based on the feedback from the pressure sensor. When the pressure sensor monitors that the contact pressure of the flexible brush filaments 122 on the shielding layer 11 is too large, it is fed back to the control system, and the control system sends a command to the second moving module, and the second moving module stops moving forward and drives the brush assembly back away from the shielding layer 11. As Figure 2 and Figure 3 As shown, the present application is further provided with a rotating module 300 , which is used to drive the breaking up module 100 to rotate, so as to increase the processing coverage of the brush on the wire harness 1 .

[0049] Specifically, the rotating module 300 includes a mounting seat 320 and a second rotating drive member 310. The breaking up module 100 is installed on the mounting seat 320. The output end of the second rotating drive member 310 is connected to the mounting seat 320 through a transmission mechanism. The second rotating drive member 310 can drive the mounting seat 320 to rotate.

[0050] It is understandable that when the second rotary drive member 310 is started, the mounting base 320 drives the overall debonding module 100 to rotate around the axis. During the rotation process, the contact angle between the combing unit 120 and the shielding layer 11 of the wire harness 1 is dynamically adjusted as the mounting base 320 rotates, so that the combing unit 120 can adapt to wire harnesses 1 of different diameters or bending shapes. For example, when there is a local bend in the wire harness 1, the rotation of the mounting base 320 can make the combing unit 120 contact the shielding layer 11 at an inclined angle, avoiding the problem of insufficient debonding due to changes in the shape of the wire harness 1, and making the debonding module 100 have axial rotational freedom. It can dynamically match the shape of the wire harness 1 without manual intervention, realizing the automatic adjustment of the contact angle between the combing unit 120 and the shielding layer 11 of the wire harness 1, effectively improving the debonding uniformity, while reducing the dependence on manual angle adjustment, and significantly improving the processing coverage.

[0051] Alternatively, in some other embodiments of the present application, the swing mechanism is connected to a first rotation driving member, the first clamping mechanism 210 is connected to the first rotation driving member, and the first rotation driving member can drive the wire harness 1 to rotate.

[0052] It can be understood that while the shielding layer 11 is being scattered and combed, the first rotating drive member is used to drive the wire harness 1 to rotate, so that the wire harness 1 has axial rotational freedom, and the shape of the wire harness 1 can be dynamically matched without human intervention, thereby realizing automatic adjustment of the contact angle between the combing unit 120 and the shielding layer 11 of the wire harness 1, effectively improving the uniformity of the scatteredness, while reducing the dependence on manual adjustment of the angle, and significantly improving the processing coverage range.

[0053] In addition, if Figure 1 As shown, the present application also proposes a method for breaking up the shielding layer 11 which is implemented by the above-mentioned shielding layer breaking up device.

[0054] Specifically, the method includes the following steps: S1: Fix the end of the wire harness 1 and place the wire harness 1 to be processed in the combing area; S2: driving at least one rotating tool with a flexible brush filament 122 close to the section to be processed of the shielding layer 11 and causing it to rotate continuously; S3: Controlling the harness 1 to perform a compound motion of swinging up and down or rotating around an axis when the rotary tool rotates; S4: Synchronously control the harness 1 or the rotary tool to move gradually along the length direction of the harness 1; S5: Metal wire combing is achieved by continuous contact between the flexible brush wire 122 and the shielding layer 11 of the composite motion harness 1.

[0055] Compound motion refers to the periodic oscillation of the wire harness 1 perpendicular to its length or periodic rotation about its axis. This can be achieved by using a servo motor to drive an oscillating mechanism or a rotating fixture, thereby disrupting the multi-directional locking of the braided structure of the shielding layer 11. Progressive movement refers to the relative displacement between the wire harness 1 and the rotating tool. This can be achieved by controlling the wire harness 1 clamping device or the rotating tool support using a linear slide.

[0056] Furthermore, in S4 , the progressive movement further includes: the rotating tool with the flexible brush filament 122 progressively moves toward the shielding layer 11 of the wiring harness 1 .

[0057] The flexible brush filaments 122 are made of conductive nylon or metal-plated polymer material, and specifically a bristle structure with a spherical end can be selected to avoid scratching the surface of the metal wire during the friction process.

[0058] It can be understood that after the end of the wire harness 1 is fixed, it is in an axial tension state, and the section of the shielding layer 11 to be processed remains straight. After the rotating tool starts to rotate, the flexible brush filaments 122 contact the surface of the shielding layer 11 in a circular motion. Driven by the swing mechanism, the wire harness 1 produces a displacement perpendicular to the axial direction, causing the metal wires of the shielding layer 11 to have a tendency to separate in the longitudinal direction. At the same time, when the wire harness 1 rotates around the axis, the circumferential winding state of the metal wires is gradually released. In this process, the wire harness 1 or the rotating tool moves progressively along the length direction of the wire harness 1, that is, starting from the end of the wire harness 1, the coverage area of ​​the shielding layer 11 of the wire harness 1 is gradually increased. In this process, the wire harness or the rotating tool moves progressively along the axial direction, so that the contact pressure of the flexible brush filaments 122 and the shielding layer gradually increases from the initial light touch to the effective combing pressure. Among them, the superposition of multi-dimensional movements causes the metal wires to displace in the longitudinal and circumferential directions at the same time, and the woven structure is non-destructively decomposed. The present application and this solution use a composite motion to separate the metal wire from the braided structure under the combined action of the longitudinal separation force generated by the swing and the circumferential untwisting force generated by the rotation, thereby solving the problems of low manual operation efficiency and high safety hazards, and avoiding destructive damage to the shielding layer 11 by hard tools. The composite motion design enables the metal wire to be efficiently separated under multi-dimensional stress conditions, and the progressive breaking and conveying ensures a smooth and controllable breaking process. The synergistic effect of the flexible brush filaments 122 and the multi-directional motion maintains the physical integrity of the metal wire while improving the uniformity of the breaking, providing a high-quality foundation for the subsequent stranding process.

[0059] The present application further proposes that in step S1, when fixing the end of the wire harness 1, an axial tensioning force is applied to the wire harness 1 so that the section to be processed of the shielding layer 11 is in a stretched and straightened state, and the tensioning direction is parallel to the length direction of the wire harness 1.

[0060] It is understood that axial tension refers to the pulling force applied along the length of the harness 1. This can be achieved using a pneumatic clamp or a servo motor-driven clamping mechanism, which mechanically applies opposing pulling forces to both ends of the harness 1. The stretched, straightened state refers to the axial tension applied to the metal wires of the shielding layer 11, eliminating their natural bends and maintaining a straight line. This can be achieved by adjusting the tension to a preset threshold. The tensioning direction is parallel to the length of the harness 1, meaning that the applied pulling force vector coincides with the axis of the harness 1. Laser positioning or guide rails can be used to ensure the straightness of the clamping mechanism's motion trajectory.

[0061] Specifically, after the ends of the wiring harness 1 are secured, axial tension is applied to both ends, resulting in uniform longitudinal stretching of the treated section of the shielding layer 11. In this state, the natural interweaving gaps between the wires of the shielding layer 11 are eliminated, forming a continuous, flat surface. For example, when a servo motor drives rollers to clamp the wiring harness 1, the torque output can be adjusted in real time via a closed-loop control system to maintain the wires of the shielding layer 11 stretched and straightened within their elastic deformation range. This stretched state provides a stable foundation for subsequent rotary tool contact, preventing fluctuations in contact pressure between the flexible brush filaments 122 and the wires due to localized relaxation of the wiring harness 1. Furthermore, the uniform stress distribution generated by axial stretching prevents breakage of the wires due to localized twisting during the combined motion. Through axial stretching and straightening, the wires are mechanically supported in the longitudinal dimension, ensuring maximum contact area between the flexible brush filaments 122 of the rotary tool and the wires. This ensures stable fixation of the treated section of the shielding layer 11, eliminates poor contact caused by natural bending of the wires, and enables the flexible brush filaments 122 to effectively comb the wires along their axial direction. At the same time, the uniform axial tension distribution avoids local stress concentration, prevents the metal wire from breaking or surface scratching during the breaking process, and improves the structural integrity of the shielding layer 11 after treatment.

[0062] The present application further proposes that during the execution of steps S3 and S4, the deformation of the wiring harness 1 is monitored in real time by a displacement sensor, and the tensioning force is dynamically adjusted to keep the deformation within a preset range.

[0063] It is understood that real-time monitoring of the deformation of the harness 1 by a displacement sensor involves placing a non-contact measuring device in the area where the combined motion and progressive motion of the harness 1 overlap. This can be achieved using a laser displacement sensor or a capacitive displacement sensor. This sensor captures the surface displacement changes of the harness 1 and generates real-time deformation data. Dynamically adjusting the tension refers to adjusting the axial tensile force of the harness 1 based on the deformation data. This can be achieved using a servo motor-driven clamping mechanism or a pneumatic actuator in conjunction with a tension controller. Deformation deviations caused by the combined motion of the harness 1 are compensated for through a closed-loop feedback mechanism.

[0064] Specifically, as the wire harness 1 periodically oscillates and rotates about its axis, the stress distribution in the contact area between its shielding layer 11 and the flexible brush filaments 122 changes dynamically. A displacement sensor acquires surface displacement data of the wire harness 1 at a fixed sampling frequency and feeds this data into the tension adjustment system. When the deformation exceeds a preset upper threshold, the servo motor drives the clamping end to move in the axial tensile direction, increasing the tension to suppress excessive deformation. When the deformation falls below a preset lower threshold, the actuator reverses its motion to reduce the tension to prevent wire breakage. This adjustment process achieves dynamic balance through the control algorithm of the control system, ensuring that the wire harness 1 remains within the elastic deformation range during the complex motion.

[0065] Beneficially, this solution achieves real-time monitoring and dynamic compensation of deformation through the coordinated control of the displacement sensor and the tension adjustment system, effectively avoiding excessive stretching or relaxation of the wire harness 1 under the superposition of compound motion and progressive motion, preventing the metal wire of the shielding layer 11 from breaking due to the deformation exceeding the yield limit of the material, and at the same time ensuring that the wire harness 1 maintains a stable straight state during dynamic processing, so that the contact pressure between the flexible brush wire 122 and the shielding layer 11 is evenly distributed, thereby improving the consistency of the combing and loosening effects of the metal wire.

[0066] The present application further proposes that, during the process of breaking up the shielding layer 11 of the wire harness 1, at least two rotating tools with flexible brushes 122 are used to symmetrically clamp the shielding layer 11 from both sides of the wire harness 1, and the two rotating tools rotate in opposite directions.

[0067] The rotating tool with flexible brush filaments 122 refers to a rotating component with a flexible conductive material covered on its surface. Specifically, it can be implemented with a cylindrical drum structure or an annular belt structure. The end of the flexible brush filament 122 can be designed to be spherical or arc-shaped to avoid damaging the shielding layer 11. Symmetrical clamping of the shielding layer 11 means that the two rotating tools are respectively located on both sides of the wire harness 1 and the axis is parallel to the axis of the wire harness 1. Specifically, the position can be adjusted by a robotic arm or a slide rail device so that the flexible brush filaments 122 form a symmetrical contact area with the shielding layer 11. Opposite rotation directions refer to the two rotating tools rotating in the clockwise and counterclockwise directions respectively. Specifically, this can be achieved by independent motor drive, and the friction tracks generated by the reverse rotation form a complementary effect. For details, please refer to Figures 2 to 3 The shielding layer breaking-up device provided by the present application is shown.

[0068] Reference Figure 2 and 3As shown in the figure, the two combing units 120 approach the shielding layer 11 synchronously from both sides of the wire harness 1, and the contact pressure of the flexible brush filaments 122 is evenly distributed along the circumference through the symmetrical layout. When the combing unit 120 rotates, the reverse rotation direction causes the flexible brush filaments 122 on both sides to form a cross friction path on the surface of the shielding layer 11. For example, when the combing unit 120 on the left rotates clockwise, its flexible brush filaments 122 contact the shielding layer 11 in a downward tilted direction, while the flexible brush filaments 122 rotating counterclockwise on the right contact in an upward tilted direction, and the movement trajectories of the two form a mesh covering on the surface of the shielding layer 11. This cross-friction can exert multi-directional force on the metal wire and effectively decompose the winding nodes of the woven structure. At the same time, the balanced pressure generated by the symmetrical clamping offsets the lateral thrust caused by the unilateral tool, preventing the wire harness 1 from shifting during the loosening process.

[0069] Advantageously, the present application utilizes a bilaterally symmetrical layout so that the force of the flexible brush filaments 122 covers the entire circumferential surface of the shielding layer 11. The bidirectional friction force generated by the reverse rotation can simultaneously act on different winding directions of the metal wire, eliminating processing blind spots. In addition, the mechanical balance formed by the symmetrical clamping structure can avoid the deviation of the wire harness 1 due to uneven force, ensure the axial stability of the wire harness 1 during the loosening process, solve the problem of uneven force on the shielding layer 11 caused by the contact of the unilateral flexible brush filaments 122, and enable the metal wire to be quickly untwisted under the action of bidirectional friction. The symmetrical clamping layout improves the coverage of the flexible brush filaments 122 on the shielding layer 11, and the cross-friction path enhances the decomposition efficiency of complex woven structures. At the same time, the balancing torque generated by the reverse rotation effectively suppresses the deviation of the wire harness 1 and ensures the stability of the posture of the wire harness 1 during the loosening process.

[0070] The present application further proposes that, during the process of unwinding the wire harness 1, the wire harness 1 simultaneously performs periodic up and down swinging perpendicular to the length direction and periodic rotation around its own axis, and the swinging and rotational motions are collaboratively controlled by independent servo motors.

[0071] It is understood that up-and-down oscillation refers to the reciprocating motion of the wire harness 1 in a plane perpendicular to its extension direction. This can be achieved by using a crank slider mechanism in conjunction with a linear guide rail, causing the metal wires in different axial positions of the shielding layer 11 to be staggered and separated. Rotation around the axis refers to the periodic rotation of the wire harness 1 about its own central axis, causing the metal wires in the shielding layer 11 to spread out circumferentially.

[0072] Specifically, during the unbundling process, the up-and-down swing of the harness 1 causes the shielding layer 11's wires to shift vertically, while its rotation around the axis gradually unwinds the wires circumferentially. The superposition of these two motions creates a three-dimensional unbundling path. Through the coordinated control of independent servo motors, the frequency, amplitude, and phase relationship between the swing and rotation can be dynamically adjusted. For example, for a high-density braided shielding layer 11, the swing frequency can be increased and the rotation speed reduced to ensure sufficient wire separation and avoid excessive entanglement.

[0073] Beneficially, the present application uses composite motion superposition and independent drive control to uniformly force the shielding layer 11 in multiple dimensions, which not only improves the breaking-up efficiency but also avoids the breakage or residue of the metal wires due to a single motion trajectory, solves the problem of insufficient separation of the metal wires caused by single-direction movement, and achieves all-round uniform breaking-up of the metal wires of the shielding layer 11. At the same time, through independent motion parameter adjustment, it adapts to the processing requirements of the shielding layer 11 with different wire diameters, weaving densities and material properties.

[0074] Alternatively, in some other embodiments of the present application, when the wire harness 1 performs periodic up and down swinging perpendicular to its length direction, the rotating tool performs circumferential revolution around the axis of the wire harness 1 while rotating on itself.

[0075] It can be understood that the circumferential revolution around the axis of the wiring harness 1 refers to the movement of the rotating tool as a whole along a circular trajectory with the wiring harness 1 as the center. Specifically, it can be achieved by using a robotic arm or a rotating platform to drive the rotating tool to move along a circular track, and the contact area between the flexible brush filament 122 and the shielding layer 11 is expanded through the revolution.

[0076] Specifically, as the wire harness 1 oscillates up and down, the rotation of the debonding module 100 causes the flexible bristles 122 to continuously scrape the surface of the shielding layer 11, while the rotation of the debonding module 100 uniformly coats the shielding layer 11 along its circumference. This combined rotation and revolution creates a spiral contact path, allowing the flexible bristles 122 to contact different locations on the shielding layer 11 during different oscillation cycles.

[0077] Advantageously, by superimposing the combined motion of rotation and revolution, the present invention enables the flexible brush filaments 122 to continuously change their contact angle and position during the swinging process, thereby improving the contact area coverage rate and dynamically expanding the contact range between the flexible brush filaments 122 and the shielding layer 11. This effectively avoids wire breakage or insulation scratches caused by localized repeated friction. The multi-angle combing effect generated by the combined motion improves the uniformity of the metal wire dispersion in the shielding layer 11, improving the efficiency of the debonding operation, while also reducing the surface damage rate of the shielding layer 11, achieving non-destructive debonding.

[0078] The present application further proposes that the progressive motion and the compound motion are executed according to one of the following timings: first execute the progressive motion to make the flexible brush filaments 122 contact the shielding layer 11 and then start the compound motion; the progressive motion and the compound motion are started synchronously; the progressive motion is executed in stages during the compound motion process.

[0079] It will be appreciated that when using the contact-first, motion-later timing mode, the combing unit 120 first translates at a constant speed until it contacts the end of the wire harness 1. Prior to contact, the shielding layer 11 is in a static state. After the combing unit 120 contacts the end of the wire harness 1, the swing mechanism and combing unit 120 are simultaneously activated, causing the wire harness 1 to begin swinging up and down. The rotational action causes the flexible brush filaments 122 to evenly comb the wires in multiple directions.

[0080] In the synchronous start-up mode, the control signals of the axial movement and the compound motion are triggered simultaneously, and the flexible brush filaments 122 begin to perform multi-angle friction during the process of establishing contact pressure, thereby shortening the process cycle.

[0081] In the staged progressive mode, the axial movement is decomposed into multiple displacement segments, and the contact depth is increased step by step during the composite movement. For example, when the friction of the flexible brush filament 122 is detected to decrease, the next stage of displacement is triggered to gradually break up the metal wire braided structure.

[0082] Advantageously, this solution uses three timing combination modes to dynamically match the contact pressure establishment process of the flexible brush filament 122 with the composite motion trajectory.

[0083] Preferably, the flexible brush filaments 122 are made of conductive nylon, metallized polymer, or stainless steel. Conductive nylon refers to a composite material with a nylon matrix and conductive fillers. Specifically, carbon fiber reinforced nylon or graphene-modified nylon can be used. Its conductive properties can eliminate interference with the metal wire combing process caused by static electricity accumulation, while maintaining moderate stiffness to avoid scratching the surface of the shielding layer 11.

[0084] Metallized polymer refers to a polymer substrate covered with a metal coating, specifically chemically nickel-plated polyester or vacuum aluminum-plated polyimide. The metal coating enhances conductivity and reduces the impact of pure metal brush filaments on the rigidity of shielding layer 11, while the polymer matrix maintains the overall flexibility of flexible brush filaments 122. Stainless steel refers to an iron-based alloy material with a chromium content of not less than 10.5%, specifically 304 austenitic stainless steel or 430 ferritic stainless steel. Its metallic ductility and wear resistance ensure that flexible brush filaments 122 maintain their morphological stability during long-term friction operations, preventing debris from contaminating wiring harness 1 due to wear.

[0085] Specifically, the conductive nylon flexible brush filaments 122, under normal working conditions, can both conduct static electricity between metal wires through their conductive properties and achieve non-destructive combing by leveraging the elastic deformation of the nylon material. The metal-plated polymer flexible brush filaments 122, by combining a surface metal layer with a polymer matrix, can meet the need for wire conduction in scenarios requiring high conductivity while also preventing the rigid scratching of the shielding layer 11 by pure metal materials. In scenarios requiring high-intensity debonding, the stainless steel brush filaments withstand repeated friction through their inherent ductility, while their wear resistance reduces the shedding of metal debris caused by breakage of the flexible brush filaments 122. The three materials are selected based on the density of the metal wires in the shielding layer 11, the required debonding strength, and the differences in the operating environment, forming solutions that cover different process requirements.

[0086] What is beneficial is that the differentiated combination of conductive nylon, metal-plated polymer and stainless steel not only solves the contradiction between electrostatic interference and material rigidity, but also adapts the material properties to different work intensity requirements, thereby achieving a balance between the breaking-up efficiency and the integrity of the shielding layer 11. It can effectively reduce the risk of breakage and splashing of the metal wire of the shielding layer 11 due to improper material selection during the breaking-up process, reduce the rigid impact damage of the flexible brush wire 122 when it contacts the shielding layer 11, and at the same time optimize the stability of the metal wire combing process through conductive properties, and ultimately achieve the simultaneous improvement of the breaking-up efficiency and work safety of the shielding layer 11 under different working conditions.

[0087] Furthermore, the ends of the flexible brush filaments 122 are spherical or arc-shaped to prevent the shielding layer 11 from being scratched.

[0088] It is understandable that when the spherical end contacts the shielding layer 11, the spherical surface forms a multi-point dispersed contact with the metal wire, so that the friction generated during the combing process is evenly distributed, avoiding local sharp friction that causes surface scratches. The arc-shaped end transitions through a smooth curvature, guiding the metal wire to slide along the arc surface when the flexible brush wire 122 and the shielding layer 11 move relative to each other, eliminating the cutting effect of the traditional right-angle end on the metal wire. During the rotation of the rotating tool and the combined movement of the wire harness 1, the end shape of the flexible brush wire 122 disperses the contact pressure and eliminates stress concentration, maintaining the original physical shape of the metal wire and preventing breakage or secondary damage caused by hard scraping. By optimizing the end shape, while maintaining the combing effect, the destructive effect of sharp contact on the shielding layer 11 is avoided, ensuring that the metal wire still has integrity and continuity after being broken up.

[0089] The present application further proposes that the axes of the two rotating tools are at an angle of 45° to 90° with the length direction of the wire harness (1) to increase the contact area between the flexible brush filaments 122 and the shielding layer, which is particularly suitable for braided shielding layers (such as cross-braided metal wires), can optimize contact efficiency, and cover multiple types of shielding layers with different wire diameters. In addition, the flexible brush filaments 122 of the two rotating tools have different wire diameters, wherein the thick wire diameter brush filaments are suitable for dense shielding layers, and the thin wire diameter is suitable for sparse shielding layers, and the thin wire diameter brush filaments reduce excessive friction on sparse shielding layers.
