Description

Technical Field

[0001] This invention belongs to the field of terminal crimping machine technology, specifically an automatic wire sorting and terminal crimping machine for multi-core wire harnesses. Background Technology

[0002] Wire harness terminals play a crucial role in the electronics and automotive industries. As the connection medium between wires and circuit boards or components, their core function is to ensure the stable transmission of current and signals. High-quality wire harness terminals must simultaneously meet electrical performance requirements and mechanical strength standards to withstand vibration, temperature changes, and external stress in complex environments, effectively preventing safety hazards such as short circuits, corrosion, and leakage, thereby improving the overall system reliability and service life. In the manufacturing process, wire harness terminals typically consist of an outer sheath, wire cores, and terminal heads. For multi-core wire harnesses, terminal assembly machines are widely used in the industry to automate the assembly process and increase the speed of terminal head assembly.

[0003] However, existing terminal crimping machines face significant challenges when handling multi-core wire harnesses: when installing multiple terminals onto multiple wire cores, operators must manually perform a pre-wiring process, which is not only time-consuming and labor-intensive, significantly slowing down production, but also introduces uncertainty due to manual intervention, making it difficult to guarantee batch consistency. While some automated wiring mechanisms attempt to mechanically flatten multiple wire cores onto the same plane before positioning and installing terminals, this design has inherent flaws. During the pressing process, the wire core surface is easily damaged by excessive pressure, causing insulation layer cracking or conductor deformation, thus affecting electrical performance. Simultaneously, wire cores are prone to overlapping or misalignment during the flattening stage, making it impossible to accurately align the terminal head with the end of each wire core, ultimately leading to unstable terminal installation, increased detachment rate, and even product failure. Summary of the Invention

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-13 As shown, this embodiment of the invention provides an automatic wire harness terminal crimping machine for multi-core wire harnesses, including a main machine base 1. Two sets of circumferential cutting wire harness components and a terminal insertion mechanism 7 are arranged on the upper end of the main machine base 1. The two sets of circumferential cutting wire harness components are slidably arranged on the upper end of the main machine base 1 and move sequentially to the terminal insertion mechanism 7 to install terminals, achieving uninterrupted terminal installation. A translation drive mechanism 2 is fixedly arranged on the upper end of the main machine base 1 for synchronously driving the movement of the two sets of circumferential cutting wire harness components. The terminal insertion mechanism 7 is used to insert terminals into the multi-core wire harness on the circumferential cutting wire harness components. The circumferential cutting wire harness components include a support base plate 3. A support frame 31 is fixedly arranged on one side of the support base plate 3. A clamping mechanism 4 is fixedly arranged on the upper end of the support frame 31. The clamping mechanism 4 is used for circumferential cutting and clamping of the multi-core wire harness. A circumferential cutting mechanism 5 is arranged on one side of the clamping mechanism 4 for circumferential cutting of the outer sheath of the multi-core wire harness. A wire harnessing mechanism 6 is fixedly arranged on the upper end of the support base plate 3 for arranging multiple cores of the multi-core wire harness side-by-side.

[0021] This embodiment effectively solves the problems of low efficiency in traditional manual wire arrangement and easy overlap and damage of wire cores during automatic wire arrangement by introducing two sets of ring-cutting wire arrangement components and terminal insertion mechanism working together, supplemented by translation drive mechanism to achieve uninterrupted operation. As a result, it realizes the automation and continuous processing of multi-core wire harnesses, significantly improves the efficiency and accuracy of terminal installation, and ensures the integrity of wire cores and the reliability of terminal connection.

[0022] In some of the embodiments described above in this application, a translation drive mechanism is proposed to drive the ring-cutting wire arrangement assembly to move. However, in practical applications, how to achieve precise, synchronous and stable reciprocating translation of multiple sets of ring-cutting wire arrangement assemblies on the main machine platform to ensure that they can accurately dock with the terminal insertion mechanism is a key technical challenge in achieving uninterrupted terminal installation.

[0023] In response, this application further proposes an automatic wire harness terminal block machine for multi-core wire harnesses; please refer to [link / reference]. Figures 5-9 As shown, the translation drive mechanism 2 includes two sets of drive plates 21 fixedly mounted on the upper end of the main machine base 1. A translation guide rail 22 and a threaded screw 23 are fixedly mounted between the two sets of drive plates 21. A drive motor 24 for driving the threaded screw 23 to rotate is fixedly mounted on one set of drive plates 21. Multiple sets of guide rail sliders 26 are slidably mounted on the translation guide rail 22. The guide rail sliders 26 are fixedly mounted on the lower end of the support base plate 3. A screw slider 25 is threadedly connected to the threaded screw 23. The screw slider 25 is fixedly connected to the lower end of the support frame 31.

[0024] Through the above technical solution, this multi-core wire harness automatic wire management and terminal crimping machine achieves high-precision displacement control of the circumferential wire management assembly on the main machine base 1 by constructing a translation drive system based on the transmission of the threaded screw 23 and the guidance of the translation guide rail 22. Specifically, the translation guide rail 22 and the threaded screw 23 are set between the two sets of drive plates 21, providing stable mechanical support and a guiding path for the movement of the circumferential wire management assembly, ensuring the stability of the assembly during movement. The drive motor 24 drives the threaded screw 23 to rotate, converting the rotational motion of the motor into the linear motion of the screw slider 25. Since the screw slider 25 is fixedly connected to the support frame 31, it drives the entire circumferential wire management assembly to move precisely back and forth along the translation guide rail 22. The fixed connection of multiple sets of guide rail sliders 26 to the support base plate 3 further enhances the anti-eccentric load capacity of the assembly during movement, ensuring that the circumferential wire management assembly can move accurately and smoothly to the terminal insertion mechanism 7, providing a reliable power transmission and position control basis for uninterrupted terminal installation. This design effectively solves the technical challenge of accurately, synchronously, and stably reciprocating multiple sets of wire-cutting assemblies on the main machine 1, ensuring that they can accurately dock with the terminal insertion mechanism 7, thereby significantly improving the efficiency and stability of the terminal installation process.

[0025] In some of the embodiments described above in this application, a clamping mechanism is proposed for circumferentially cutting and fixing multi-core wire harnesses. However, in actual operation, how to achieve uniform, stable and synchronous clamping of multiple wire cores to avoid displacement or uneven force on the wire harness during circumferential cutting, thereby affecting the accuracy of subsequent terminal insertion, is a problem that urgently needs to be solved in the prior art.

[0026] For this, please refer to Figures 5-9 As shown, this application proposes a clamping mechanism, which includes a fixed sleeve 41 fixedly mounted on a support frame 31. The fixed sleeve 41 is provided with a plurality of arc-shaped clamping plates 42 arranged in a ring array. The arc-shaped clamping plates 42 are radially slidably mounted in the fixed sleeve 41 for clamping multi-core wire harnesses. A clamping plate connecting rod 47 is fixedly mounted on the outer side of the arc-shaped clamping plates 42. The clamping plate connecting rod 47 is slidably connected to the side wall of the fixed sleeve 41. A clamping drive mechanism is provided on the outer periphery of the fixed sleeve 41 for synchronously driving the plurality of arc-shaped clamping plates 42 to slide radially.

[0027] Through the above technical solution, the clamping mechanism 4 utilizes the arc-shaped clamping plates 42 arranged in a ring array inside the fixed sleeve 41. Under the synchronous drive of the clamping drive mechanism, the arc-shaped clamping plates 42 slide radially, thereby uniformly and stably clamping the multi-core wire harness. The clamping plate connecting rod 47 serves as a transmission medium, connecting the radial movement of the arc-shaped clamping plates 42 with the external clamping drive mechanism. This design ensures that the wire harness is subjected to uniform force when clamped, avoiding deformation or damage to the wire harness caused by single-point compression. The introduction of the clamping drive mechanism ensures the consistency of the movement of all arc-shaped clamping plates 42, thereby stably fixing the multi-core wire harness in the central position and effectively preventing the wire harness from shaking or shifting during the circumferential cutting process. In the multi-core wire harness automatic wire sorting and terminal crimping machine, this stable clamping method provides a reliable foundation for the subsequent ring cutting mechanism 5 to perform precise ring cutting, and also provides accurate positioning for the wire sorting mechanism 6 to sort multiple wire cores side by side and the terminal insertion mechanism 7 to insert terminals. This significantly improves the working accuracy and automation level of the entire terminal crimping machine, reduces the scrap rate caused by wire harness instability, and thus improves production efficiency and product quality.

[0028] In some of the embodiments described above in this application, a clamping mechanism is proposed for circumferentially cutting and fixing multi-core wire harnesses. However, in actual operation, how to achieve synchronous and precise radial sliding of multiple sets of arc-shaped clamps to adapt to the clamping requirements of wire harnesses of different specifications, and ensure the mechanical transmission stability and reliability of the clamping action, is the technical challenge faced by this mechanism.

[0029] For this, please refer to Figures 5-9As shown, this application further proposes a clamping drive mechanism, which includes a clamping upright plate 44 fixedly disposed on the outer periphery of the fixed sleeve 41 and a drive turntable 43 rotatably connected to the outer periphery of the fixed sleeve 41. The drive turntable 43 is provided with a plurality of drive grooves 431, and a drive connecting rod 48 is slidably disposed at the drive grooves 431. The drive connecting rod 48 is fixedly connected to the clamping plate connecting rod 47. A clamping motor 45 is fixedly installed on the clamping upright plate 44, and a clamping gear 46 is fixedly installed on the output shaft of the clamping motor 45. A turntable rack 432 that meshes and is transmitted with the clamping gear 46 is fixedly disposed on the drive turntable 43.

[0030] Through the above technical solution, this application constructs a linkage mechanism based on gear and rack meshing transmission and drive groove drive, effectively solving the problems of synchronous and precise radial sliding of multiple sets of arc-shaped clamping plates 42, as well as the stability and reliability of mechanical transmission in clamping action. Specifically, the clamping motor 45 drives the clamping gear 46 to rotate, and the clamping gear 46 meshes with the turntable rack 432 on the drive turntable 43, accurately converting the rotational motion of the clamping motor 45 into the circumferential rotation of the drive turntable 43. This gear and rack transmission method has the advantages of stable transmission ratio, high transmission accuracy, and strong load-bearing capacity, ensuring the smoothness and synchronization of power transmission. Multiple drive grooves 431 on the drive turntable 43 cooperate with the drive connecting rod 48 to convert the circumferential rotation of the drive turntable 43 into the radial displacement of the drive connecting rod 48, thereby driving the clamping plate connecting rod 47 and the arc-shaped clamping plates 42 to perform synchronous radial sliding within the fixed sleeve 41. This design allows multiple sets of arc-shaped clamps 42 to contract or expand uniformly and synchronously around the center of the multi-core wire harness, thereby achieving stable clamping of the multi-core wire harness and avoiding damage or unstable fixation caused by uneven clamping. Simultaneously, the geometric design of the drive groove 431 allows for precise control of the clamping stroke of the arc-shaped clamps 42, enabling it to adapt to the clamping requirements of multi-core wire harnesses of different diameters. This significantly improves the versatility and operational stability of the automatic multi-core wire harness crimping machine when handling diverse wire harnesses, ensuring the smooth progress of subsequent circumferential cutting and terminal insertion processes.

[0031] In some of the embodiments described above in this application, a circumferential cutting mechanism is proposed for circumferential cutting of the outer sheath of multi-core wire harnesses. However, in actual operation, how to achieve precise positioning, stable movement, and effective guidance of the cutting blade at different positions during the circumferential cutting process to ensure the consistency of the circumferential cutting depth and the cutting quality is a aspect that needs further optimization in the prior art.

[0032] For this, please refer to Figures 5-9As shown, this application further proposes a circumferential cutting mechanism 5, which includes a circumferential cutting guide rail 51 fixedly disposed on the outer periphery of a fixed sleeve 41, a circumferential cutting slide block 53 slidably disposed on the circumferential cutting guide rail 51, a cutting seat plate 56 fixedly disposed on the upper part of the circumferential cutting slide block 53, a cutting telescopic cylinder 57 fixedly mounted on the cutting seat plate 56, a cutting blade 58 for cutting the outer sheath of a multi-core wire harness fixedly connected to the output end of the cutting telescopic cylinder 57, and a cutting blade guide seat 59 for slidingly guiding the cutting blade 58 fixedly disposed on the lower part of the circumferential cutting slide block 53.

[0033] Through the above technical solution, a circumferential cutting guide rail 51 is set on the outer periphery of the fixed sleeve 41, providing a stable motion trajectory for the circumferential cutting slide 53 and ensuring the spatial positional stability of the cutting mechanism during the circumferential cutting process. The cutting seat plate 56, as the main load-bearing body, uses a cutting telescopic cylinder 57 to achieve radial feed control of the cutting blade 58, allowing the cutting blade 58 to flexibly adjust its cutting depth according to the wire harness diameter. The output end of the cutting telescopic cylinder 57 is connected to the cutting blade 58, enabling precise control of the start, stop, and force of the cutting action, thereby avoiding unnecessary damage to the internal wire core. The cutting blade guide seat 59 is located at the lower part of the circumferential cutting slide 53, its function being to slide and guide the cutting blade 58, physically restricting its swing or deviation during the circumferential cutting process, ensuring that the cutting blade 58 always maintains the correct posture on the circumferential cutting path, thereby improving the flatness and consistency of the outer sheath circumferential cutting. This structural design, through the dual guidance of the guide rail and the guide seat, effectively solves the problem that the cutting blade 58 is prone to deviating from the track or uneven force during the circumferential cutting process, providing a reliable mechanical guarantee for achieving high-quality wire harness sheath stripping.

[0034] In some of the embodiments described above in this application, a ring-cutting mechanism is proposed for ring-cutting the outer sheath of a multi-core wire harness. However, in its implementation, relying solely on the cutting blade of the ring-cutting mechanism for radial cutting makes it difficult to achieve complete circumferential stripping of the wire harness outer sheath. Furthermore, the cutting blade lacks precise power transmission and guiding support when rotating around the wire harness, which can easily lead to uneven cutting depth or cutting path deviation, thereby affecting the removal quality of the wire harness outer sheath.

[0035] For this, please refer to Figures 5-9 As shown, the circumferential cutting mechanism 5 also includes an annular rack 52 fixedly disposed on the outer periphery of the fixed sleeve 41, a circumferential cutting motor 54 fixedly mounted on the circumferential cutting slide 53, and a circumferential cutting gear 55 fixedly mounted on the output shaft of the circumferential cutting motor 54. The circumferential cutting gear 55 meshes with the annular rack 52 for transmission, driving the circumferential cutting slide 53 to rotate circumferentially along the circumferential cutting guide rail 51 to perform circumferential cutting on the outer sheath of the multi-core wire harness.

[0036] Through the above technical solution, when circumferentially cutting the outer sheath of a multi-core wire harness, the circumferential cutting mechanism 5 provides a stable track and precise transmission reference for the circumferential movement of the circumferential cutting slide 53 by fixing an annular rack 52 around the outer circumference of the fixed sleeve 41. The circumferential cutting motor 54 drives the circumferential cutting gear 55 on its output shaft to mesh with the annular rack 52, accurately converting the rotational power of the motor into the circumferential movement of the circumferential cutting slide 53 along the circumferential cutting guide rail 51. Compared with other non-meshing transmission methods, this gear and rack meshing transmission method can provide more stable and precise power output, effectively avoiding the problems of insufficient power, unstable transmission, or path deviation that may occur when the cutting blade 58 rotates around the wire harness. The precise engagement of the ring cutting gear 55 and the ring rack 52 ensures that the ring cutting slide 53 can rotate smoothly and evenly around the central axis of the multi-core wire harness. This allows the cutting blade 58 to perform a uniform and circumferential ring cut on the outer sheath of the wire harness, effectively solving the technical problems of incomplete or uneven sheath cutting. This significantly improves the quality and efficiency of sheath stripping, providing a high-quality processing foundation for subsequent wire core arrangement and terminal insertion processes.

[0037] In some of the embodiments described above in this application, a cable management mechanism is proposed for managing multi-core wire harnesses. However, in actual operation, it is difficult to ensure that multiple wire cores maintain a high degree of flatness and stability when arranged side by side by a simple cable management mechanism. Furthermore, if there is a lack of precise lifting and positioning control during the pressing of the wire cores into the wire groove, the wire cores may be displaced, overlapped, or subjected to uneven force when pressed, which may affect the accuracy and reliability of subsequent terminal insertion.

[0038] In response, this application further proposes an automatic wire harness terminal block machine for multi-core wire harnesses; please refer to [link / reference]. Figures 10-11 As shown, the cable management mechanism 6 includes a cable management base 61 fixedly mounted on the upper end of the support base plate 3. The upper end of the cable management base 61 is provided with multiple base grooves 611 for cable management. Base support plates 612 are fixedly mounted on both sides of the cable management base 61. A vertically upward cable management telescopic cylinder 62 is fixedly installed on one set of base support plates 612. The output end of the cable management telescopic cylinder 62 is fixedly connected to a lifting bracket 63. The lower end of the lifting bracket 63 is provided with a bracket guide rod 631 that is slidably connected to another set of base support plates 612. A cable management support 64 is movably mounted laterally on the inner side of the lifting bracket 63. A cable management pressure seat 65 for squeezing the wire core and managing the cable is slidably mounted vertically on the cable management support 64. The lower end of the cable management pressure seat 65 is provided with a pressure seat groove 651 that cooperates with the base grooves 611.

[0039] Through the above technical solution, the cable management base 61 and its base groove 611 provide initial positioning and arrangement space for multi-core wire harnesses. The cable management telescopic cylinder 62 drives the lifting bracket 63 to move vertically, and with the guiding action of the bracket guide rod 631, ensures the stable movement of the cable management mechanism in the vertical direction, avoiding swaying or tilting during the lifting process. The lateral movable setting of the cable management support 64 inside the lifting bracket 63 allows the cable management pressure seat 65 to be finely adjusted in the horizontal direction, thereby adapting to the width and arrangement requirements of different wire harnesses and ensuring that the wire cores can be accurately aligned. The vertical sliding of the cable management pressure seat 65 on the cable management support 64, combined with the cooperation of the pressure seat groove 651 at its lower end and the base groove 611, can accurately and evenly squeeze and fix multiple wire cores in their respective grooves, effectively avoiding the problems of displacement, overlap or uneven force of the wire cores during compression. This multi-dimensional and refined cable management structure significantly improves the flatness and stability of multi-core wire harnesses, providing a reliable foundation for the precise operation of the subsequent terminal insertion mechanism 7. This improves the efficiency and quality of terminal installation and solves the problems of inaccurate cable management and easy damage to the wire cores in existing technologies.

[0040] In some of the embodiments described above in this application, a cable management mechanism is proposed for arranging multi-core cable bundles side by side. However, during the process of the cable management press directly pressing the core, the lack of a flexible buffer mechanism and rigid contact can easily damage the surface of the core and make it difficult to ensure the uniformity of the pressing force, thereby affecting the quality of cable management.

[0041] For this, please refer to Figures 10-11 As shown, the inner side of the cable management support 64 is provided with a support guide rail 641 for limiting the lifting and sliding of the cable management pressure seat 65. The upper end of the cable management pressure seat 65 is fixedly provided with a capped pin 66, which is slidably connected to the top wall of the cable management support 64. A top pressure spring 67 is provided between the cable management pressure seat 65 and the top wall of the cable management support 64. The top pressure spring 67 is sleeved on the outer circumference of the capped pin 66. The elasticity of the top pressure spring 67 realizes the movable connection of the cable management pressure seat 65, and the elasticity of the top pressure spring 67 also protects the cable core when pressing and managing the cable core.

[0042] Through the above technical solution, in the cable management mechanism 6, the support guide rail 641 provided inside the cable management support 64 provides precise guidance for the lifting and lowering movement of the cable management pressure seat 65, ensuring its stability in the vertical direction. The capped pin 66, as a connecting component, not only limits the detachment range of the cable management pressure seat 65 but also provides an installation reference for the top pressure spring 67. The top pressure spring 67 is sleeved on the outer circumference of the capped pin 66. When the cable management pressure seat 65 presses down to contact the wire core, the spring deforms, converting the originally rigid impact force into flexible pressure. This elastic compensation mechanism allows the cable management pressure seat 65 to automatically adjust the pressure according to the actual thickness of the wire core, ensuring uniform force on multiple wire cores and avoiding wire core deformation or insulation layer damage caused by excessive pressure. This structural design not only improves the safety of the cable management process and effectively solves the problem of wire core damage caused by rigid compression, but also ensures the flatness of the wire core in the cable management groove 611 through elastic adaptive adjustment, laying the foundation for the efficient and stable installation of subsequent terminals, thereby significantly improving the cable management quality and terminal installation efficiency of multi-core wire harnesses.

[0043] In response, this application further proposes a cable management mechanism for managing multi-core cable bundles. However, in the process of the cable management support moving laterally to press and manage the cable cores, relying solely on mechanical structure drive can easily lead to insufficient pressure control between the cable management pressure seat and the cable cores, and it is difficult to achieve flexible reciprocating cable management action, resulting in a difficulty in balancing cable management efficiency and cable core protection effect.

[0044] To resolve the above issues, please refer to Figures 10-11 As shown, the cable management support 64 has support rods 642 fixedly installed on both outer walls. The support rods 642 are slidably connected to the side wall of the lifting bracket 63. A support spring 643 is installed between the outer wall of the cable management support 64 and the side wall of the lifting bracket 63. The support spring 643 is sleeved on the outer circumference of the support rod 642. Fixed magnets 68 are fixedly installed on both outer walls of the cable management support 64. An electromagnet 69 that cooperates with the fixed magnets 68 is installed on the inner side wall of the lifting bracket 63. The horizontal sliding of the cable management pressure seat 65 is achieved by the magnetic attraction and repulsion between the fixed magnets 68 and the electromagnet 69 to press and manage the cable core.

[0045] Through the above technical solution, the lateral movement of the cable management support 64 no longer relies on a purely mechanical structure, but is driven non-contactly by the magnetic attraction and repulsion between the fixed magnet 68 and the electromagnet 69. This magnetic drive method enables precise control of the horizontal sliding position of the cable management holder 65, and by adjusting the current of the electromagnet 69, the pressing force applied to the cable core can be dynamically adjusted, thus effectively solving the problem of inaccurate pressure control in the cable management process of traditional mechanical drives. At the same time, the cooperation between the support connecting rod 642 and the support spring 643 not only provides stable guidance and support for the cable management support 64, but also protects the cable core when pressing the cable through the elastic buffering effect of the support spring 643, avoiding damage to the cable core that may be caused by rigid pressing. In addition, the fast response and flexible action of the magnetic drive enable the cable management holder 65 to perform more precise and flexible reciprocating cable management actions, significantly improving the cable management efficiency of multi-core cable bundles. While ensuring the cable management effect, it also protects the integrity of the core to the greatest extent, achieving a balance between cable management efficiency and core protection effect.

[0046] In some of the solutions described above in this application, a terminal insertion mechanism is proposed for installing terminals on multi-core wire harnesses. However, in actual automated production processes, how to accurately and efficiently connect pre-organized wire harnesses to terminals, and ensure that terminals can be stably transferred from the transport carrier to the wire core, is a key challenge in achieving full automation. Existing insertion methods often lack coordinated control over terminal transport and positioning, which can easily lead to terminal misalignment or displacement during insertion, thus affecting the quality and efficiency of terminal installation.

[0047] For this, please refer to Figures 12-13 As shown, this application further proposes a terminal insertion mechanism 7, which includes an insertion plate 71 fixedly mounted on the upper end of the main machine base 1. Connecting shafts 73 are rotatably mounted on both sides of the insertion plate 71. Transmission pulleys 74 are fixedly mounted on the connecting shafts 73. The two sets of transmission pulleys 74 are connected by a transmission belt 75. A plurality of terminal seats 751 for placing terminals are evenly arranged on the transmission belt 75. A conveying motor 76 for driving the connecting shafts 73 to rotate is fixedly mounted on the insertion plate 71. The upper end of the insertion plate 71 is fixedly provided with a support top plate 72 for supporting the upper transmission belt 75. The insertion plate 71 is fixedly provided with an insertion telescopic cylinder 77. The output end of the insertion telescopic cylinder 77 is fixedly connected to an insertion connecting plate 78. The insertion connecting plate 78 is fixedly provided with a plurality of pressing connecting rods 79 for pushing the terminals from the terminal seat 751 to the wire core in the wire management mechanism 6.

[0048] Through the above technical solution, this application effectively solves the problems of accuracy and efficiency in terminal conveying and wire core mating in multi-core wire harness automatic wire sorting and terminal crimping machines. Specifically, by setting a connecting shaft 73 driven by a conveyor motor 76 and a transmission pulley 74 on the insertion plate 71, the transmission belt 75 is driven to circulate. Multiple terminal holders 751 evenly arranged on the transmission belt 75 can continuously and orderly convey terminals to the insertion station. This cyclic conveying mechanism ensures the continuity and automation of terminal supply, avoiding the inefficiency and instability caused by manual intervention. At the same time, the setting of the supporting top plate 72 provides stable support for the upper transmission belt 75, effectively preventing the transmission belt 75 from sagging or shaking when running at high speed or carrying terminals, thereby ensuring the stability and positioning accuracy of the terminal holders 751 during the conveying process, laying the foundation for subsequent accurate insertion. Furthermore, by driving the insertion connecting plate 78 through the insertion telescopic cylinder 77, multiple pressing connecting rods 79 fixedly installed on the insertion connecting plate 78 can synchronously and accurately push the terminal out of the terminal holder 751 and onto the already arranged wire core in the wire management mechanism 6. This design decouples the terminal delivery from the insertion action. Utilizing the stable thrust of the telescopic cylinder 77, it ensures that the terminal can be accurately and stably installed onto the end of the wire core, effectively avoiding the problems of terminal offset, misalignment, or even damage to the wire core that are prone to occur in traditional insertion methods. In summary, the terminal insertion mechanism 7, together with the two sets of ring-cutting wire management components on the main machine base 1 and the wire management mechanism 6, achieves full automation, high efficiency, and high precision in the process from terminal supply and positioning to final insertion. This significantly improves the overall performance and production efficiency of the multi-core wire harness automatic wire management terminal machine, and reduces labor costs and product defect rate.

[0049] The following example will provide a more detailed explanation of the above technical solution: In an electronics manufacturing plant, automated terminal assembly is required for a large number of multi-core wire harnesses. Traditional terminal assembly machines often require manual pre-sorting of the wires when handling multi-core wire harnesses. This is not only time-consuming but also prone to damage or overlap of the wires due to improper operation, thus affecting the accuracy and efficiency of terminal assembly. To solve these problems, the plant introduced a new type of automated multi-core wire harness sorting and terminal assembly machine.

[0050] The automatic wire feeding and terminal crimping machine includes a main machine base 1. At the upper end of the main machine base 1, two sets of ring-cutting wire feeding assemblies and a terminal insertion mechanism 7 are installed. This dual-ring-cutting wire feeding assembly design is key to achieving uninterrupted production. While one set of ring-cutting wire feeding assemblies is processing wire harnesses, the other set can be loaded or prepared simultaneously, thus avoiding waiting time. A translation drive mechanism 2 is also fixedly installed at the upper end of the main machine base 1, used to synchronously drive the two sets of ring-cutting wire feeding assemblies to move sequentially on the upper end of the main machine base 1, enabling them to accurately move to the terminal insertion mechanism 7 for terminal installation.

[0051] First, a multi-core wire harness to be processed is manually or automatically fed into the first set of circumferential cutting and wire management components. After the multi-core wire harness is fed in, the clamping drive mechanism drives the arc-shaped clamp 42 to slide synchronously along the radial direction, circumferentially cutting and fixing the multi-core wire harness. This design of the arc-shaped clamp 42 can evenly clamp the outer sheath of the wire harness, avoiding local stress concentration and wire harness damage that may be caused by traditional clamps.

[0052] After clamping is complete, the circumferential cutting mechanism 5 begins operation. After the circumferential cutting motor 54 starts, the circumferential cutting gear 55 meshes with the annular rack 52, driving the circumferential cutting slide 53 to rotate circumferentially along the circumferential cutting guide rail 51. Simultaneously, the cutting telescopic cylinder 57 extends, allowing the cutting blade 58 to precisely circumferentially cut the outer sheath of the multi-core wire harness without damaging the internal wire cores. The cutting blade guide 59 provides sliding guidance for the cutting blade 58 during the cutting process, ensuring cutting stability.

[0053] After the outer sheath is circumcised, the cable management mechanism 6 begins to arrange the multiple cores of the multi-core cable harness side by side. When the cable management telescopic cylinder 62 drives the lifting bracket 63 to descend, the cable management pressure seat 65, under the elastic action of the top pressure spring 67, gently presses the cores and guides them into the base cable groove 611 and the pressure seat cable groove 651. The presence of the top pressure spring 67 provides a buffering effect during the pressing process, effectively protecting the cores and avoiding damage that may be caused by traditional hard flattening.

[0054] To achieve precise horizontal alignment of the wire cores, support rods 642 are fixedly installed on both outer walls of the wire alignment support 64, slidingly connected to the side walls of the lifting bracket 63. A support spring 643 is installed between the outer wall of the wire alignment support 64 and the side wall of the lifting bracket 63, sleeved around the outer circumference of the support rods 642. More importantly, fixed magnets 68 are fixedly installed on both outer walls of the wire alignment support 64, while an electromagnet 69 cooperating with the fixed magnets 68 is installed on the inner wall of the lifting bracket 63. By controlling the magnetic attraction and repulsion of the electromagnet 69, the wire alignment support 64 can be precisely driven to slide laterally within the lifting bracket 63, thereby causing the wire alignment press 65 to perform precise horizontal pressing and alignment of the wire cores. This magnetic control method, combined with spring buffering, ensures that each wire core is accurately and without damage arranged side-by-side, solving the problem of wire core overlap that easily occurs in traditional methods.

[0055] After the first set of wire-cutting and tidying assemblies completes wire tidying, the translation drive mechanism 2 starts working; the drive motor 24 starts, driving the threaded screw 23 to rotate. Through the cooperation of the screw slider 25 and the guide rail slider 26, the first set of wire-cutting and tidying assemblies is precisely translated to the terminal insertion mechanism 7. At the same time, the second set of wire-cutting and tidying assemblies can begin to load new multi-core wire harnesses and perform wire-cutting and tidying, realizing an uninterrupted production process and significantly improving overall efficiency.

[0056] When the multi-core wire harness, after being properly organized, reaches the terminal insertion mechanism 7, the insertion telescopic cylinder 77, fixedly mounted on the insertion stand 71, begins to operate. An insertion connecting plate 78 is fixedly connected to the output end of the insertion telescopic cylinder 77. Multiple pressing rods 79 are fixedly mounted on the insertion connecting plate 78 to push the terminals from the terminal holder 751 onto the wire cores within the wire organization mechanism 6. The insertion telescopic cylinder 77 retracts, driving the pressing rods 79 to push the terminals at the corresponding positions on the transmission belt 75 out of the terminal holder 751 and precisely insert them into the ends of the already neatly arranged wire cores in the wire organization mechanism 6. Because the wire cores have undergone precise organization, overlap and misalignment are avoided, making the terminal insertion process stable, efficient, and accurate.

[0057] After the terminal insertion is completed, the first set of ring-cutting and wire management components returns to its initial position under the drive of the translation drive mechanism 2, ready for the loading and processing of the next wire harness. The entire process realizes fully automated and uninterrupted production from wire harness clamping, outer sheath ring cutting, wire core management to terminal insertion, which greatly improves the efficiency and quality of multi-core wire harness terminal installation, while effectively avoiding the damage to the wire core that may be caused by traditional manual operation and existing automatic wire management mechanisms.
