Description
Technical Field
[0001] The present invention relates to the technical field of wire harness processing automation, and in particular to a multi-wire harness and terminal assembly device and method. Background Art
[0002] A multi-wire harness is a structure consisting of two or more wires or cables bundled together in a specific arrangement to achieve the centralized transmission and organizational management of multiple signal or power pathways in complex electrical systems. It is widely used in the fields of automotive manufacturing, industrial control equipment, instrumentation, consumer electronics, communication systems, etc., especially between vehicle wire control systems, sensor networks and complex electronic devices, playing a core role in signal and power transmission. In actual applications, multi-wire harnesses need to be connected to multiple metal terminals for subsequent plug-in, fixation or modular integration. By accurately inserting or connecting multiple wires into the corresponding terminal structure, the stability and safety of the electrical connection are ensured.
[0003] In the existing technology, the assembly process of multi-wire harnesses and terminals is usually distributed across multiple independent workstations, and each step relies on manual or mechanical transmission equipment to complete collaborative work. The general process includes: first, separating the wires in the harness and positioning them according to a preset layout, then pre-processing the wires separately, and then introducing them into the corresponding terminals, and connecting them by crimping or plugging. This distributed assembly process has many limitations: the equipment layout is complex, the space occupied is large, the process connection is not tight, it is easy to introduce positioning errors and connection deviations, and it is difficult to meet the needs of high-speed and high-precision automated assembly. Especially in customized, multi-model and small-batch production scenarios, the existing system lacks flexible integration capabilities.
[0004] In view of the shortcomings of existing assembly devices in terms of precision control, process integration and degree of automation, there is an urgent need for systematic improvements at the device structure level.

Therefore, the present invention proposes a multi-wire harness and terminal assembly device and an assembly method thereof with optimized structure, high functional integration and strong adaptability, aiming to break through the limitations of existing technologies and achieve the assembly goals of high automation, high precision and flexible coordination of multiple wires and multiple terminals.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0023] In the modern automotive industry, with the continuous advancement of vehicle intelligence and electrification, the electronic systems used in vehicles are becoming increasingly complex. This is particularly true in the fields of autonomous driving and electric vehicles, where numerous multi-wire harnesses are required to connect sensors, batteries, control modules, and various electrical devices. Traditional wiring harness and terminal assembly methods often suffer from insufficient assembly precision, low production efficiency, and frequent manual intervention, failing to meet the demands of high-precision, high-efficiency, and customized production.
[0024] Imagine an automobile manufacturer needs to produce a customized electrical wiring harness for a new vehicle model. This vehicle features a complex electrical system, requiring each wire harness to be precisely connected to a specific terminal block. Furthermore, the length, structure, and terminal block pairing of each harness must be tailored to the specific vehicle configuration. Traditional production methods typically require multiple workstations and rely on extensive manual labor, which not only increases production cycle time but also easily leads to connection errors or substandard assembly.
[0025] In this context, the multi-wire harness 01 and terminal 03 assembly device of the present invention can significantly improve production efficiency and accuracy. First, the terminal 03 loading mechanism automatically separates and transports the terminals 03 via a vibrating plate 21 and a cutting assembly 22, avoiding the instability and errors associated with traditional manual assembly. During the terminal 03 inspection phase, a visual recognition assembly 33 ensures the quality of each terminal 03, eliminating the possibility of unqualified terminals 03 entering the assembly process and thus ensuring the stability of the electrical connection.
[0026] Next, the wire harness feeding mechanism 5 and positioning assembly 52 precisely position the wire harness, providing a precise foundation for subsequent wire harness threading. The wire harness threading mechanism 6, utilizing multiple wire core 02 clamping assemblies and combined with the automatic adjustment function of the second drive element 61b, quickly and accurately guides each wire core 02 into the desired position, rotating and adjusting it appropriately. This process no longer relies on manual labor or complex robotics, but is instead accomplished through an intelligent control system, making the assembly process more efficient and precise.
[0027] When some multi-core 02 wire harnesses are combined with terminal 03, for example, terminal 03 has four holes, such as Figure 1 As shown, there are four multi-wire cores 02, and the holes in the terminal 03 are arranged in a circular arrangement. However, the wiring harness was processed on the same plane in the previous stage. The wiring harness needs to be moved to achieve the position correspondence between the cores 02 and the terminals 03. The cores 02 need to be clamped by the clamps and pulled to different positions. The present invention provides a device that can realize this assembly.
[0028] like Figures 2 to 17 The multi-wire harness 01 and terminal 03 assembly device shown includes: Rack 1; The terminal 03 feeding mechanism includes a vibration disk 21 and a cutting assembly 22 arranged at the output end of the vibration disk 21. The cutting assembly 22 separates a single terminal 03. In some embodiments of the present invention, the outer periphery of some terminals 03 has a serrated structure. When separating two adjacent terminals 03, if the two terminals are moved horizontally, the serrated mechanism will cause the terminals to be unable to move apart. In the embodiments of the present invention, the two adjacent terminals 03 are cut apart by vertical movement using the cutting mechanism, so there will be no problem of being unable to move apart or the two terminals 03 being stuck.
[0029] The terminal 03 detection mechanism includes a terminal 03 placing component, a terminal 03 transfer component that transfers the terminal 03 on the cutting component 22 to the terminal 03 placing component, the terminal 03 transfer component includes a horizontal sliding member 32a and a longitudinal sliding member 32b, and a visual recognition component 33 for detecting the quality of the terminal 03 on the terminal 03 placing component, and the terminal 03 placing component also includes a rotating member 31a; in some embodiments of the present invention, the terminal 03 has a plurality of hole positions, and the wire core 02 of the wiring harness is passed through the middle. The insertion of the wire core 02 has a set position, and the direction of the terminal 03 also has a set position. In order to prevent the position of the terminal 03 from rotating or deviating, the position of the terminal 03 is judged by visual recognition, and then the terminal 03 is rotated by the rotating member 31a to make the terminal 03 reach the set position, so as to improve the yield of the wiring harness.
[0030] The terminal 03 conveying mechanism includes a transverse transmission assembly 41, a longitudinal transmission assembly 42 connected to the transverse transmission assembly 41, and a conveying clamp 43 fixed on the longitudinal transmission assembly 42; the terminal 03 conveying mechanism transports the terminals 03 in each mechanism to each workstation.
[0031] The wire harness feeding mechanism 5 includes a wire harness clamping claw 51 for clamping the wire harness and a positioning component 52 for positioning the inner core of the wire harness; The wire harness threading mechanism 6 includes a plurality of wire core 02 clamping assemblies and a wire core 02 rotating assembly. The wire core 02 clamping assembly includes a wire core 02 clamping claw for clamping a single wire core 02 on the positioning assembly 52, and a second driving member 61b for driving the wire core 02 clamping claw to move relatively closer to or away from the positioning assembly 52. In some embodiments of the present invention, the wire core 02 clamping assembly is used to grab the individual wire cores 02 and then move them to the position where the terminal 03 threads through the shell. During the early processing of the wire harness, all the wire cores 02 are on the same plane. In order to achieve a circular layout of the wire cores 02, the two middle wire cores 02 can be rotated 90 degrees so that the two wire cores 02 are located in opposite positions.
[0032] like Figure 1As shown, the present invention integrates various processes into an efficient and integrated system through a compact frame 1 structure. First, the terminal 03 feeding mechanism automatically separates the terminal 03 accurately through the vibration plate 21 and the cutting assembly 22, providing a reliable supply of terminals 03 for subsequent assembly. The terminal 03 detection mechanism uses a visual recognition component 33 and a precise placement device to ensure the quality and accuracy of each terminal 03, thereby avoiding subsequent problems caused by unqualified terminal 03 quality. Unlike traditional devices, the present invention introduces high-precision control in the links of terminal 03 transfer, positioning and detection, ensuring the precise pairing of terminals 03. In addition, the wire harness feeding mechanism 5 accurately positions the wire harness through the wire harness clamp 51 and the positioning assembly 52, providing efficient guarantee for the subsequent wire harness shell penetration. The wire harness shell penetration mechanism 6 realizes flexible processing of multiple wire cores 02 through the wire core 02 clamping assembly and the rotating assembly. Traditional assembly processes typically require manual intervention or complex mechanical means to adjust the position of each wire core 02. However, the second drive member 61b of the present invention can automatically adjust the position of the wire core 02 clamp, making the entire assembly process more automated and precise. By efficiently integrating these functional modules, the present invention not only improves assembly accuracy but also reduces errors between process steps, avoiding the frequent manual intervention and error accumulation in traditional assembly methods. Compared to traditional distributed assembly methods, this device can efficiently complete the precise assembly of multi-wire harnesses 01 and terminals 03 in a compact space, greatly improving the automation level of the production line and reducing labor costs.
[0033] refer to Figure 3 、 Figure 4 As shown, the cutting assembly 22 includes an output seat 22a connected to the output end of the vibration disk 21, and a first driving member 22b fixedly connected to the output seat 22a. The first driving member 22b drives the output seat 22a to move perpendicularly to the extension direction of the vibration disk 21, and the terminal 03 is away from the vibration disk 21. The cutting assembly 22 drives the output seat 22a to move in a direction perpendicular to the extension direction of the vibration disk 21 through the first driving member 22b, ensuring that the terminal 03 can be accurately separated from the vibration disk 21 and effectively away from the vibration disk 21. This design greatly reduces the error in the separation process of the terminal 03 and the problem of the terminals 03 being inseparable, and avoids the situation in which the terminal 03 may get stuck or be incompletely separated in the traditional device. In addition, the precise control of the first driving member 22b makes the entire process more automated, reduces the dependence on manual labor, and improves production efficiency.
[0034] like Figure 5 、 Figure 6As shown, the terminal 03 placement assembly includes a receiving seat 31b provided on the frame 1 for placing the terminal 03, and a first clamping piece 31c provided on one side of the receiving seat 31b for clamping the terminal 03. The receiving seat 31b can be relatively close to or away from the terminal 03 transfer assembly on the frame 1. The terminal 03 placement assembly in the present invention is achieved through a receiving seat 31b that can move forward and backward and a lateral clamping structure. The receiving seat 31b is installed on the frame 1 and can make a linear movement of approaching and moving away near the terminal 03 transfer assembly; when the transfer clamp is in place, the receiving seat 31b actively moves forward to meet it, realizing zero-distance handover between the terminal 03 and the platform, significantly reducing the falling impact and position drift of the terminal 03. Subsequently, the first clamping piece 31c located on the side of the receiving seat 31b immediately clamps the terminal 03, realizing rigid positioning and limiting its rotation, achieving higher posture consistency than traditional passive blanking platforms. After the receiving seat 31b returns to its original position, the terminal 03 is taken away with the receiving seat 31b, which does not occupy the travel time of the transfer component; unnecessary alignment actions are eliminated, the cycle time is shortened, and the equipment production capacity is improved. It should be noted here that the receiving seat 31b, which can move the component towards or away from the terminal 03, can be used to receive the terminal 03, or it can be used to press the terminal 03 when the terminal 03 is placed down to make it fit more closely with the receiving seat 31b.
[0035] Continue to refer Figure 6 As shown, the receiving seat 31b also includes an elastic compression member 31d provided on the frame 1, one end of the elastic compression member 31d is connected to the receiving seat 31b, and the other end is connected to the frame 1. When the terminal 03 is placed on the receiving seat 31b, there may be a situation where the terminal 03 and the receiving seat 31b do not fit directly, there is a gap, or the terminal 03 is not placed properly. To reduce the occurrence of this situation, in some embodiments of the present invention, the elastic compression member 31d is used to reduce the occurrence of this situation. When the terminal 03 is put down, the receiving seat 31b is pressed, and the receiving seat 31b and the terminal 03 fit tightly. When the clamping claw is released, due to the elasticity of the elastic compression member 31d, it is the receiving seat 31b that drives the terminal 03 back to the initial position.
[0036] Continue to refer Figure 6As shown, between the receiving seat 31b and the frame 1 is a rotating member 31a, which is connected to the visual recognition component 33 and is used to rotate the angle of the terminal 03 on the receiving seat 31b. The visual orientation of the terminal 03 can be inaccurate, leading to docking errors, requiring the robot to re-grasp or adjust it, increasing the cycle time. Furthermore, after the terminal 03 is separated by the vibrating plate 21 and the cutting component 22, its posture when it finally lands on the receiving seat 31b will still have angular deviations. For subsequent precise crimping or insertion of the clamping jaws, a dedicated flipping station must be added or repeated adjustments must be made by the robot, which not only increases the cycle time but also accumulates errors. To address this pain point, the present device mounts the receiving seat 31b on the frame 1 via the controllable rotating member 31a, and establishes a real-time closed-loop connection with the visual recognition component 33: the visual system first performs high-resolution photography and angle measurement of the terminal 03 on the receiving seat 31b, then the rotating member 31a is controlled to precisely rotate the receiving seat 31b, adjusting the terminal 03 to the standard angle required for the process. In this way, the terminal 03 can complete the posture correction in situ after it is seated, without the need for additional handling and flipping mechanism, eliminating the cumulative error and surface damage caused by multiple grasping. like Figures 7 to 10 As shown, the terminal 03 conveying mechanism also includes a slider 44 slidably connected to the transverse transmission assembly 41, a flip member 45 rotationally connected to the slider 44, a longitudinal transmission assembly 42 connected to the other end of the flip member 45, and a conveying clamp 43 connected to the other end of the longitudinal transmission assembly 42. The present invention adopts a multi-degree-of-freedom integrated structure of "transverse transmission assembly 41-slider 44-flip member 45-longitudinal transmission assembly 42-conveying clamp 43" in the terminal 03 conveying mechanism: the slider 44 slides linearly along the transverse transmission assembly 41 to achieve precise X positioning, and the flip member 45, with its rotational hinge with the slider 44 as the center, can complete any angle flipping of 0-180 degrees during movement, smoothly switching the terminal 03 from a horizontal posture to a vertical or specified angle; then, the longitudinal transmission assembly 42 at the other end of the flip member 45 performs a Y / Z direction composite lifting and lowering, driving the conveying clamp 43 to accurately deliver the terminal 03 to the crimping or insertion station. Through this coordinated "slide-flip-lift" linkage action, the three-axis motion is compressed into a compact kinematic chain, eliminating the need for an additional flipping station. This shortens the conveying path, reduces the time the terminals 03 are exposed in mid-air, and avoids surface damage caused by multiple grasping. Compared with traditional serial split mechanisms, this solution significantly improves cycle efficiency and posture control accuracy, while reducing mechanical complexity and maintenance costs.
[0037] Continue to refer Figure 9 、 Figure 10As shown, the conveying jaws 43 are equipped with multiple sensor elements 43a. These sensors 43a pass through the terminals 03 and into their interior, contacting the wire cores 02. In traditional automated assembly of multi-wire harnesses 01, the crimping or insertion of the terminals 03 and wire cores 02 often relies on mechanical limit stops and manual spot checks to confirm insertion force and depth. This provides no real-time information on whether each wire core 02 is fully seated or whether there are potential problems such as loose strands, bends, or loose connections. This can lead to problems such as high contact resistance or intermittent open circuits only being exposed after assembly, resulting in costly repairs and a reduction in production cycle times. The present device integrates multiple slender sensor elements 43a on the conveying jaws 43. When the jaws grasp the terminals 03, these sensors can penetrate the terminal 03 cavity and directly contact the wire cores 02 to be assembled. By measuring minute contact pressure, displacement, or conduction signals, the device can instantly detect the insertion depth, contact surface condition, and conduction reliability of the wire cores 02, and feed this data back to the control system. This creates a closed-loop assembly process: if the sensor detects that core 02 doesn't meet the standard, the equipment can immediately pause crimping or perform a secondary compensation action, ensuring that each assembly is completed within the ideal parameter window. Compared to the traditional "post-assembly spot check, then rework" model, this "built-in gripper - real-time detection" solution moves the quality checkpoint to the moment of assembly, significantly reducing defect rates and rework time. It also provides precise and stable online quality assurance for high-speed, high-mix wire harness production.
[0038] like Figures 12 to 14 As shown, the positioning assembly 52 includes two opposing tooth blocks 52a, a third driver that drives the two tooth blocks 52a toward or away from each other, and two wire harness positioning blocks 52b positioned between the tooth blocks 52a and the harness clamp 51. The harness positioning blocks 52b also include a fourth driver that drives the two wire harness positioning blocks 52b toward or away from each other. The present invention introduces two positioning mechanisms, one for tooth separation and one for positioning, into the positioning assembly 52. The tooth blocks 52a and the third driver can be opened or closed synchronously, acting like a "comb," quickly pre-splitting the entire bundle of wires. Next, the two wire harness positioning blocks 52b, located between the tooth blocks 52a and the harness clamp 51, tighten or loosen the bundle under the action of the fourth driver, achieving precise correction of the bundle's center position and roundness. This automatically centers the bundle before the clamp grips it, ensuring balanced tension and straight alignment of each wire core 02. This facilitates the subsequent clamping of the wire core 02 to the desired position.
[0039] like Figure 15 、 Figure 16As shown, the core 02 rotation assembly includes a clamping block 62a for clamping the core 02, a turntable 62b that drives the clamping block 62a to rotate to a set angle, and a fifth drive member that drives the clamping block 62a to move closer to or further away from the tooth block 52a. The clamping block 62a has at least two grooves for fixing the core 02. The present invention provides a clamping block 62a with at least two grooves for fixing the core 02 in the core 02 rotation assembly, and achieves programmable angle rotation under the drive of the turntable 62b. The fifth drive member is also used to control the approach or distance of the clamping block 62a relative to the tooth block 52a. First, the integrated design of the turntable 62b and the clamping block 62a allows multiple cores 02 to rotate synchronously within the same coordinate system, ensuring consistent output angles and completely eliminating the error accumulation caused by manual adjustment of each core. Second, the multi-slot structure on the clamping block 62a can lock multiple cores 02 at once, ensuring consistent tension of the cores 02 and quickly adapting to different wiring schemes without the need to replace dedicated clamps. Integrating wire core 02 angle correction, tension balancing and coaxial synchronization into one action significantly shortens the cycle time, improves assembly accuracy, and provides a truly flexible and automated solution for high-variety small-batch production.
[0040] According to the second aspect of the present invention, a method for assembling a multi-wire harness 01 and a terminal 03 is also provided. Figure 18 As shown in , the following steps are included: S10: The vibration plate 21 conveys the terminal 03 to the cutting assembly 22, and the cutting mechanism cuts out the terminal 03 individually; S20: The terminal 03 transfer component takes the terminal 03 out of the cutting component 22, transfers it to the terminal 03 placement component, and presses the terminal 03 so that the terminal 03 fits the terminal 03 placement component; S30: The visual recognition component 33 moves to the terminal 03 placement component, inspects the terminal 03, and determines whether the terminal 03 is defective. If so, the terminal 03 conveying mechanism picks it up and discards it; if not, it determines whether the placement angle of the terminal 03 is correct. If not, the terminal 03 is rotated to the set angle. S40: The terminal 03 identified by the visual recognition mechanism is transported to a position to be inserted into a shell and waited for by the terminal 03 transport mechanism; S50: Fix the wire harness by using the wire harness feeding mechanism 5, and position the inner cores arranged in sequence by using the positioning assembly 52; S60: The two middle wires 02 arranged in sequence are clamped by the wire core 02 rotating assembly and rotated to a set position; S70: Using multiple wire core 02 clamping assemblies to clamp each wire core 02 to a set position; S80: Transport terminal 03 on the terminal 03 transport mechanism to the position of wire core 02, so that wire core 02 passes into terminal 03, and completes the assembly of multi-wire harness 01 and terminal 03.
[0041] The entire assembly process starts from the vibration disk 21: the vibration disk 21 queues the terminals 03 in order and sends them to the cutting component 22, the first driving member 22b drives the output seat 22a to rise and fall vertically, cuts out a single terminal 03 and rises back to be taken; the terminal 03 transfer component then moves horizontally to the cutting position, the longitudinal sliding member 32b descends to allow the conveying clamp 43 to pick up the terminal 03, and then rises and moves at high speed to the terminal 03 placement component, and the terminal 03 is firmly attached to its surface under the buffering cooperation of the receiving seat 31b and the elastic compression member 31d; the visual recognition component 33 rises to the top to take the image of the terminal 03. If it is detected as a defective product, the clamp is instructed to take it out again and discard it. After the defective products are filtered out, the rotating member 31a is driven to fine-tune the angle of the receiving seat 31b according to the visual feedback; the qualified and correct-posture terminal 03 is driven by the horizontal transmission component 41 to slide the slider 44, and the flipping member 45 completes the horizontal-vertical flip on the way, and the longitudinal transmission component 42 descends to suspend the terminal 03 Stop at the position to be inserted into the shell; at this time, the wire harness is fixed by the wire harness clamping claw 51, and the tooth block 52a opens the coarse bundle under the action of the third driving member. The wire harness positioning block 52b is fine-tuned and clamped by the fourth driving member to achieve centering, and outputs the "wire harness in place" signal; the fifth driving member drives the clamping block 62a to grab the two middle wire cores 02, and the turntable 62b rotates it synchronously to the set angle, and then multiple wire core 02 clamping components are extended at the same time, each correcting and straightening the remaining wire cores 02 so that their center lines coincide with the axis of the terminal 03 hole and the tension is balanced; after the controller confirms that the tension data of all wire cores 02 are qualified, the longitudinal transmission assembly 42 descends again, and the slender sensor on the conveying clamping claw 43 passes through the terminal 03 cavity to detect the position and conduction status of the wire core 02 in real time. After confirmation, the clamping claw continues to apply pressure to complete the insertion or crimping, and immediately samples the insertion force curve and conduction resistance to determine the quality. The good products are immediately released and conveyed to the next process. If the force-electricity parameters are abnormal, an alarm will be issued and the product will be stopped for repair.
