Description

Technical Field

[0001] This application relates to the field of wire harness processing technology, specifically to a wire harness shaping and positioning device. Background Technology

[0002] Existing flexible wire harness shaping and positioning technologies are primarily designed for wire harnesses made of harder materials with low springback rates. Their positioning methods often employ partial fixing or disassembly, using rigid clamps to apply pressure to specific areas of the wire harness to achieve positional constraints. While these technologies can meet the basic positioning requirements of rigid wire harnesses, they are limited by the inherent rigidity of the wire harness itself and do not require additional control over springback deformation. For flexible wire harnesses made of softer materials that are prone to springback deformation, such as when multiple wire harnesses have poor parallelism or are intertwined, local positioning cannot constrain the overall degrees of freedom, easily leading to springback deformation in non-fixed areas and making it difficult to maintain the target posture. Furthermore, multiple flexible wire harnesses are prone to intertwining during positioning, and traditional clamps cannot effectively separate them and maintain parallelism, lacking a systematic control mechanism for wire harness springback deformation. Utility Model Content

[0003] To address the problems in existing technologies where flexible wire harnesses are difficult to shape and position due to their soft and elastic material, and where multiple wire harnesses are prone to crossing and difficult to maintain a parallel state.

The gripper assembly includes a wire separating pin, a pressure block, and a contouring gripper. The wire separating pin is used to insert into the gap between the wire harnesses. The pressure block is pressed onto the upper surface of the wire harness. The contouring gripper has a contouring groove on its inner side to guide the wire harness to a parallel state. The wire straightening assembly includes a wire separating needle, a pressure block, a contouring gripper, and a wire separating gripper; the wire separating gripper and the contouring gripper are spaced apart, and the wire separating gripper is positioned near the end of the wire harness; the wire straightening assembly is configured to move relative to the gripper assembly to perform a wire straightening operation on the wire harness; The wire harness positioning component is located below the wire harness shaping component.

[0005] Furthermore, the wire separating pin, pressure block, and contoured gripper of the gripper assembly are arranged at intervals along the direction from the rubber shell to the end of the wire harness.

[0006] Furthermore, the wire-straightening assembly's contoured gripper, wire-separating pin, pressure block, and wire-separating gripper are arranged sequentially at intervals along the direction from the rubber shell to the end of the wire harness.

[0007] Furthermore, the cross-section of the dividing needle along its length is tapered.

[0008] Furthermore, a gap is provided between the lower surface of the pressure block and the upper surface of the wire harness.

[0009] Furthermore, the wire harness positioning assembly includes a positioning platform, and the positioning platform is provided with at least one positioning groove. The positioning groove includes a wire harness guide groove and a housing guide groove that are connected to each other. The housing guide groove has a guide inclined surface structure.

[0010] Furthermore, a rubber shell pusher is slidably disposed on one side of the rubber shell guide groove, and the rubber shell pusher is used to push the rubber shell to slide along the rubber shell guide groove.

[0011] Furthermore, at least one movable wire harness pressing block is provided on one side of the wire harness guide groove, and the wire harness pressing block is configured to be movable above the wire harness guide groove and perpendicular to it.

[0012] Furthermore, a position control probe is provided on one side of the wire harness guide groove, and the position control probe is configured to be movable above the wire harness guide groove.

[0013] Furthermore, gap control blocks are provided on both sides of the wire harness guide groove, and the gap control blocks on both sides are arranged opposite to each other.

[0014] Implementing the embodiments of this application has the following beneficial effects: The wire harness shaping assembly of this application includes a gripper assembly located near the housing end of the wire harness to be shaped. This assembly uses a wire separating pin inserted into the gap between the wire harnesses to achieve initial separation, a pressure block pressed against the upper surface of the wire harness to prevent lifting, and a contouring groove on the inner side of the gripper, working in conjunction with the wire separating pin and pressure block, to guide the wire harness to a parallel state when closed. This effectively solves the problems in existing technologies where flexible wire harnesses are difficult to shape due to their soft and springy material, and multiple wire harnesses are prone to crossing and tangling, making it difficult to maintain a parallel state. The straightening assembly can move relative to the gripper assembly, straightening the wire harness into a completely straight shape with two wire harnesses remaining parallel and without crossing, further eliminating potential slight bending, twisting, or local crossing defects in the wire harness. The wire harness positioning assembly located below the wire harness shaping assembly uses mechanical positioning to fix the straightened wire harness and housing as a whole, ensuring that the wire harness and housing do not shift during subsequent processes.

[0022] The wire harness shaping and positioning device of this application includes a wire harness shaping component 100 and a wire harness positioning component 200, which work together to shape and precisely position the wire harness product 300, respectively. The wire harness product 300 to be shaped includes a housing 301 and a wire harness 302 connected to the housing 301, wherein the wire harness 302 includes at least two flexible wires.

[0023] The wire harness shaping assembly 100 includes a frame, a gripper assembly 1, and a wire straightening assembly 2. The gripper assembly 1 and the wire straightening assembly 2 are fixed on the frame, and the gripper assembly 1 and the wire straightening assembly 2 cooperate to perform wire splitting, guiding and straightening operations on the wire harness.

[0024] The gripper assembly 1 is located at one end of the wire harness 302 to be shaped, near the housing 301. The gripper assembly 1 includes a wire separating pin 11, a pressure block 12, and a contouring gripper 13. The wire separating pin 11 is used to insert into the gap between the wire harnesses 302. The pressure block 12 is pressed against the upper surface of the wire harness 302. The contouring gripper 13 has a contouring groove 131 on its inner side. When the contouring gripper 13 is closed, the contouring groove 131, together with the wire separating pin 11 and the pressure block 12, guides the wire harness 302 to a parallel state. The wire separating pin 11, the pressure block 12, and the contouring gripper 13 of the gripper assembly 1 are connected by a mechanical structure such as a fixing bracket or an integrated substrate to form an integrated structure.

[0025] The thread separator 11 has a needle-like structure and can be inserted into the gap between the thread bundles 302 along a direction perpendicular to the extension of the thread bundle. It is used to separate the contact areas between the thread bodies of the bundle, preventing them from tangling and crossing. Preferably, the cross-section of the thread separator 11 along its length is tapered, and the small-diameter end of the tapered structure can extend into the gap between the thread bundles. In some possible embodiments, the thread separator 11 may also adopt a cylindrical structure, but the tapered design is more conducive to precise gap positioning.

[0026] The pressure block 12 has a flat, block-like structure with a small gap between its lower surface and the upper surface of the wire harness 302. This gap is designed with tolerance control to allow the pressure block 12 to gently press against the upper surface of the wire harness, preventing the wire harness 302 from lifting upwards during shaping while avoiding excessive compression that could deform the wire harness 302. The width of the lower surface of the pressure block 12 is greater than the total width of the parallel wire harnesses 302. In some possible embodiments, the pressure block 12 can be connected to a fixed bracket via an elastic element such as a spring to achieve adaptive adjustment of the pressing force.

[0027] In this embodiment, the contouring gripper 13 includes a movable gripper structure and a fixing structure. The inner side of the gripper structure is provided with a contouring groove 131. Preferably, the contouring groove 131 can be a semi-circular groove or an arc-shaped groove. The cross-sectional shape of the contouring groove 131 matches the outer diameter profile of the wire harness 302. When the gripper structure and the fixing structure are closed, the inner wall of the contouring groove 131 contacts the outer surface of the wire harness 302, and guides the wire harness to a parallel state through lateral pressure. Specifically, the opening direction of the contouring groove 131 faces the centerline of the wire harness, and when closed, it squeezes the outer side of the wire harness to bring it closer to the center, ultimately making the wires of the wire harness parallel to each other without crossing.

[0028] Furthermore, the gripper assembly 1 includes a gripper drive assembly, which drives the contour gripper 13 to achieve opening and closing actions. Specifically, the contour gripper 13 can be opened and closed by a cylinder and linkage structure, or by an electric push rod or other structure. The movable gripper structure and the fixed structure of the contour gripper 13 can also be configured to be hinged by a pivot, and in its natural state, it is kept closed by spring preload; when it needs to be opened, the gripper is pushed by an electromagnet or a manual lever to overcome the spring force and separate.

[0029] In this embodiment, the wire separating pin 11, the pressure block 12, and the contouring gripper 13 of the gripper assembly 1 are arranged sequentially at intervals along the direction from the housing 301 to the tail end of the wire harness 302, that is, from the connection end of the wire harness and the housing to the free end of the wire harness. The wire separating pin 11 contacts the gap in the wire harness first to keep the wire harness 302 separated from the connection end of the housing 301. The pressure block 12 presses against the upper surface of the wire harness 302 to prevent it from lifting. The contouring gripper 13 closes to guide the wire harness and keep the wire harness 302 parallel.

[0030] The cable straightening assembly 2 cooperates with the clamping jaw assembly 1 to further straighten the cable bundle after initial cable separation and alignment. The cable straightening assembly 2 includes a cable separating pin 11, a pressure block 12, and a contouring clamping jaw 13, as well as a cable separating jaw 14. The structures of the cable separating pin 11, pressure block 12, and contouring clamping jaw 13 are identical to their corresponding structures in the clamping jaw assembly 1. The cable separating jaw 14 is spaced apart from the contouring clamping jaw 13, and is positioned near the tail end of the cable bundle 302. In this embodiment, the contouring clamping jaw 13, cable separating pin 11, pressure block 12, and cable separating jaw 14 of the cable straightening assembly 2 are sequentially spaced apart along the direction from the housing 301 to the tail end of the cable bundle 302.

[0031] The wire straightening assembly 2 is configured to move relative to the gripper assembly 1 to perform a wire straightening operation on the wire harness 302.

[0032] In practical applications, the wire harness shaping assembly 100 includes a first driving mechanism 4 and a second driving mechanism 5. The driving end of the first driving mechanism 4 is connected to the wire harness shaping assembly 100 through a fixed bracket and is used to drive the gripper assembly 1 and the wire straightening assembly 2 to move up and down to perform material picking and unloading operations. The driving end of the second driving mechanism 5 is used to connect to the wire straightening assembly 2 and is used to drive the wire straightening assembly 2 to move relative to the gripper assembly 1 along the wire harness extension direction. The wire straightening assembly 2 and the gripper assembly 1 can be connected by a guide rail slider structure.

[0033] Like the wire separating pin 11, the wire separating claw 14 can move perpendicular to the extension direction of the wire harness to a position between the two wire harnesses, and can also move to one side to separate the two wire harnesses. The wire separating claw 14 can be opened and closed by cooperating with the cylinder and linkage structure connected to it, or by a structure such as an electric push rod.

[0034] In the initial position, the wire harness shaping assembly 100 of this application has the wire straightening assembly 2 and the gripper assembly 1 positioned close to each other at the housing end. After the material handling action is initiated, the wire separating pins 11 of the gripper assembly 1 and the wire straightening assembly 2 work together to insert downwards into the gap between the flexible wire harness 302 to be shaped, and the pressure block 12 presses against the upper surface of the wire harness 302. The conforming gripper 13 of the gripper assembly 1 and the conforming gripper 13 of the wire straightening assembly 2 close together, and the nearby wire harness is guided to a parallel state by lateral pressure. The flexible wire harness 302 is gradually constrained from its initial disordered state to a parallel and non-crossing posture. Subsequently, the wire straightening assembly 2 moves linearly relative to the gripper assembly 1 along the wire harness extension direction to straighten the wire harness 302. During the straightening process, the contour gripper 13 of the wire straightening assembly 2 remains closed. The movement of the wire straightening assembly 2 applies a tensile force and lateral friction force along the length direction to the wire harness, eliminating any slight bending, twisting, or local crossing that may exist in the wire harness. Ultimately, the two wire harnesses are straightened into a completely straight state, and the two wire harnesses maintain a parallel and non-crossing posture.

[0035] The wire harness positioning component 200 is located below the wire harness shaping component 100. It is used to receive the shaped wire harness product 300 and fix the wire harness product 300 to the designated position by mechanical positioning to ensure that the position of the wire harness product 300 does not shift in subsequent processes.

[0036] Furthermore, the wire harness positioning assembly 200 includes a positioning platform 3, on which at least one positioning groove 31 is provided. The positioning groove 31 includes a wire harness guide groove 311 and a housing guide groove 313 that are connected to each other. The housing guide groove 313 has a guide slope structure.

[0037] In one possible implementation, the upper surface of the positioning platform 3 is provided with two parallel and spaced-apart positioning grooves 31.

[0038] The wire harness guide groove 311 is a strip-shaped groove structure, and its cross-sectional shape matches the outer diameter contour of the wire harness 302, such as a semi-circular or arc-shaped groove, to accommodate and constrain the horizontal position of the wire harness 302. In this embodiment, the wire harness 302 includes two flexible wires, and the wire harness guide groove 311 has a dividing protrusion in the middle, dividing it into two wire guide grooves.

[0039] The end of the wire harness guide groove 311 is provided with a housing guide groove 313 communicating with it. The housing guide groove 313 has a guide slope structure, and its inclination angle is designed to facilitate the housing 301 to slide in from one end, such as 30°~60°. In one possible embodiment, the groove width of the housing guide groove 313 gradually decreases towards the end closer to the wire harness guide groove 311.

[0040] Furthermore, a plastic shell pusher 314 is slidably provided on one side of the plastic shell guide groove 313. The plastic shell pusher 314 is used to push the plastic shell 301 to slide along the plastic shell guide groove 313 to a designated position.

[0041] In this embodiment, the housing pusher 314 can be configured as a push rod structure, with one end extending above the housing guide groove 313 and the other end positioned on one side of the housing guide groove 313 via a linear guide rail or slider. The housing pusher 314 can move along the housing guide groove 313 under the drive of a driving component, such as a cylinder or drive motor. During the sliding process of the housing 301 through the housing guide groove 313, the housing pusher 314 contacts the housing 301, pushing the housing 301 to slide.

[0042] Furthermore, at least one movable wire harness pressing block 315 is provided on one side of the wire harness guide groove 311. The wire harness pressing block 315 is configured to be movable above the wire harness guide groove 311 and perpendicular to it.

[0043] In one possible implementation, a sliding groove is provided on one side of the wire harness guide groove 311, and one end of the wire harness pressing block 315 is connected to the sliding groove. It can move through the sliding groove to the top of the wire harness guide groove 311. When the wire harness 302 is placed in the wire harness guide groove 311, the wire harness pressing block 315 moves to the top of the wire harness guide groove 311 and presses down on the upper surface of the wire harness 302 to prevent the wire harness from tilting upward or shifting during the positioning process.

[0044] In another possible implementation, one end of the wire harness clamping block 315 is disposed on one side of the wire harness guide groove 311 via a hinge structure. When the wire harness 302 is placed in the wire harness guide groove 311, the wire harness clamping block 315 rotates to be above the wire harness guide groove 311 and presses down on the upper surface of the wire harness 302.

[0045] Furthermore, a position control probe 317 is also provided on one side of the wire harness guide groove 311, and the position control probe 317 is located near the tail end of the wire harness guide groove 311. The position control probe 317 is configured to be movable above the wire harness guide groove 311. In one possible embodiment, the position control probe 317 can be a position sensor disposed above the wire harness guide groove 311. In a specific implementation, the position control probe 317 includes a sensing module and a fine-tuning execution module. The sensing module is a displacement sensor, such as a capacitive proximity sensor, a photoelectric sensor, or a laser displacement sensor, which can monitor the relative position between the upper surface of the wire harness 302 and the probe in real time. The fine-tuning execution module includes a miniature linear drive mechanism, which can be a piezoelectric ceramic actuator, a miniature cylinder, or a servo motor with a ball screw. The fine-tuning execution module is connected to the sensing module and can drive the probe contact of the sensing module to move in a direction perpendicular to the extension direction of the wire harness guide groove 311. The position control probe 317 is fixed to the upper surface of the positioning stage 3 by a modular bracket, and the installation position is such that the projection area of ​​the probe contact can cover the lateral width of the wire harness guide groove 311.

[0046] During operation, the wire harness position control probe 317 can sense the upward tilt or offset of the tail end of the wire harness 302 in real time through the sensing module. The fine-tuning execution module controls the probe contact to press down, and performs local constraint on the key area of ​​the tail end of the wire harness that is prone to crossing, effectively avoiding the problem of wire harness crossing and ensuring that the flexible wire harness is parallel and without crossing after positioning.

[0047] Furthermore, gap control blocks 316 are respectively provided on both sides of the wire harness guide groove 311, and the gap control blocks 316 on both sides are arranged opposite to each other. The gap control blocks 316 are symmetrically distributed on the left and right sides of the wire harness guide groove 311. The gap control blocks 316 have a block structure, and their inner surface is flush with or slightly recessed inward with the side wall of the wire harness guide groove 311, which is used to limit the lateral offset of the wire harness 302.

[0048] Furthermore, the positioning stage 3 is also provided with alignment grooves 318 that respectively cooperate with the contouring grippers 13 of the gripper assembly 1 and the contouring grippers 13 of the wire straightening assembly 2. When the wire harness shaping assembly 100 moves downward to place the shaped wire harness product 300 into the wire harness positioning assembly 200, the contouring grippers 13 of the gripper assembly 1 and the contouring grippers 13 of the wire straightening assembly 2 match the corresponding alignment grooves 318 to achieve precise alignment of the gripper assembly 1 and the wire straightening assembly 2, and to improve the placement accuracy of the wire harness product.

[0049] The wire harness positioning assembly uses mechanical positioning methods, including a wire harness clamping block holding the upper end of the wire harness, a housing pusher block pushing the housing and wire harness to move synchronously, and a gap control block limiting the lateral displacement of the wire harness. These structures secure the straightened wire harness and housing as a whole, ensuring that they do not shift during subsequent processes. By incorporating wire harness clamping blocks, gap control blocks, and position control probes, the assembly systematically manages the springback deformation of the wire harness, preventing it from crossing or shifting again due to material elastic recovery. This systematically solves the technical bottlenecks of existing technologies, such as difficulties in shaping and positioning flexible wire harnesses, inaccurate positioning of multiple wire harness crossings, and uncontrolled springback deformation. It achieves a complete shaping and positioning process for flexible wire harnesses, from an initial messy state to a parallel, non-crossing, specific posture and precise positioning. This significantly improves the accuracy, stability, and reliability of flexible wire harness shaping and positioning, meeting the automated processing needs of flexible electronic devices, automotive wiring harnesses, and other fields.

[0050] After the wire harness shaping component 100 completes the straightening operation of the wire harness 302, it moves the shaped wire harness product 300 as a whole above the wire harness positioning component 200, places the wire harness product 300 into the wire harness positioning component 200, and then performs the following positioning action: The wire harness clamping block 315 and the position control probe 317 move to press the upper end of the wire harness 302, initially fixing the position of the wire harness 302. The wire splitting claws 14 in the wire harness shaping assembly 100 open, stretching the tail of the wire harness 302 into a V-shape to increase the separation angle of the tail and prevent the tail from crossing; at the same time, the contouring claws 13 in the claw assembly 1 and the wire straightening assembly 2 open, and the wire harness shaping assembly 100 moves upward and away from the wire harness area. When the housing pusher 314 in the wire harness positioning assembly 200 is activated, it pushes the housing 301 to slide along the housing guide groove 313, and the wire harness 302 moves within the wire harness guide groove 311 until the wire harness product 300 is positioned in the designated position.
