Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire processing equipment technology, specifically a top wire assembly. Background Technology
[0002] With the increasing sophistication of high-precision electronic assembly and high-speed signal transmission harness processing, precise positioning and length control of wires during the final assembly stage have become crucial for ensuring overall electrical matching, structural adaptability, and long-term reliability. This is especially true in high-speed wire products with multi-core parallel connections and high-frequency transmission, where each wire must not only be connected to a specific port but also maintain high consistency in length, contact angle, and stress distribution. However, current industrial wire positioning methods are largely based on traditional fixed slots, guide slots, or rigid bracket structures. Their design philosophy leans towards row-wide guidance and batch alignment, failing to meet the precise requirements for spatial fine-tuning and differential compensation of individual wires. Furthermore, with the increasing demand for irregular terminal structures, high-density solder joints, and rapid changeovers, traditional wire harness positioning methods have several limitations in terms of flexibility, adaptability, and stress fatigue resistance.
[0003] According to the investigation, the existing wire positioning technology has the following main defects:
[0004] 1. Traditional wire guiding structures are mostly fixed slots or overall brackets for positioning, which cannot perform precise height control on individual wires. Especially when dealing with electrical products with different terminals, pins or interface structures, slight differences in wire length or contact surface may lead to assembly difficulties or poor soldering.
[0005] 2. In actual use, wire harness products often correspond to various electrical structures of different models, and the corresponding processing dimensions and wire allowance lengths also vary. If adjustments are made manually or by changing fixtures, it is not only inefficient but also subject to human error.
[0006] 3. In traditional fixed wire clamp devices, the wires must be arranged at the same reference height. However, due to differences in the assembly height of the product port or the setting of the fixture, some wires may be forced to be stretched or compressed, which will cause hidden fatigue cracks at the root of the wire or the solder joint over time. Utility Model Content
[0007] The purpose of this application is to provide a technical solution to address the problems mentioned in the background section.
[0008] To achieve the above objectives, this application provides the following technical solution:
[0009] A top wire assembly, characterized in that it includes a base, at least one top wire rod, and at least one top wire rod driving device, wherein the top wire rod driving device is connected to the top wire rod and moves it to any position on the base.
[0010] Preferably, a guide plate is also installed on the base, the guide plate has a top rod guide opening, and the top rod driving device is connected to the top rod to move and position it at the top rod guide opening.
[0011] Preferably, a top groove is also formed on the top of the top wire rod.
[0012] Preferably, a top roller is also installed on the top of the top wire rod.
[0013] Preferably, the top groove is arc-shaped.
[0014] Preferably, the top wire rod is in the shape of a sheet or a column.
[0015] Preferably, it further includes at least one pressure block and at least one pressure block driving device, wherein the pressure block driving device is connected to the pressure block and moves it to the guide plate on the upper side of the top rod guide opening.
[0016] Preferably, the pressure block is cylindrical.
[0017] Preferably, the pressure block also has a pressure groove.
[0018] Preferably, the top wire rod driving device and the pressure block driving device are respectively a cylinder or a motor.
[0019] In summary, the technical effects and advantages of this utility model are as follows:
[0020] 1. This solution enables each wire to be independently controlled by the top wire rod, allowing the user to specify the length before assembly, thus meeting the user's controllable requirements for wire length. Furthermore, it simplifies the production process and reduces wire waste due to the adjustable function, saving manufacturing costs.
[0021] 2. The top line assembly of this solution realizes the programmed control of the lifting and lowering action of the top line rod through the drive device (which can be a cylinder, electric push rod or stepper servo system). Under different product requirements, the preset stroke height data can be automatically called to realize quick changeover and quick grouping and selection of wire materials, which significantly improves the flexibility and response speed of the automated production line.
[0022] 3. The finely adjustable top rod in this solution can actively compensate for the original height difference of the wires, so that all wires are in a stress-released state or an equal stress state after installation, which significantly delays the risk of wire damage, breakage or poor contact caused by structural stress, and improves the long-term reliability and assembly stability of the product.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figures 1-7A top-line assembly includes a base 1, at least one top-line rod 2, and at least one top-line rod drive device 3. The top-line rod drive device 3 is connected to the top-line rod 2 and moves it to any position on the base 1. This solution utilizes the independent control capability of each top-line rod 2, allowing each wire to be of a user-specified length before assembly, thus meeting the user's controllable requirements for wire length. Furthermore, it simplifies the production process and reduces wire waste due to its adjustable function, saving manufacturing costs. The drive device of this top-line assembly (which can be a cylinder, electric push rod, or stepper servo system) can programmatically control the lifting and lowering of the top-line rod. It can automatically recall preset stroke height data under different product requirements, enabling rapid changeover and rapid grouping and selection of wires, significantly improving the flexibility and response speed of automated production lines. The precisely adjustable top rod 2 in this solution can actively compensate for the original height differences of the wires, so that all wires are in a stress-released state or an equal stress state after installation. This significantly delays the risk of wire damage, breakage or poor contact caused by structural stress, and improves the long-term reliability and assembly stability of the product.
[0034] Preferably, a guide plate 01 is also installed on the base 1. The guide plate 01 has a top rod guide opening 11. The top rod driving device 3 is connected to the top rod 2 and moves it to the top rod guide opening 11. By setting the top rod guide opening 11, the top line path of this solution is more controllable, thereby achieving more precise top line action and improving production quality.
[0035] Preferably, the top of the top wire rod 2 is further formed with a top wire groove 21, which is arc-shaped. The design of the top wire groove 21 is not only for limiting function; its arc-shaped structure provides a semi-enclosed support geometry, so that the wire maintains a stable cross-sectional fit during the lifting process, reducing the risk of local stress concentration and wire jumping caused by point contact. The arc profile also has good sliding guidance, which can effectively guide the wire to achieve a uniform radius path movement during the lifting and falling dynamic process, further suppressing the deflection or kinking problems caused by wire rigidity differences or contact friction. It is especially suitable for high-frequency micro-coaxial or shielded twisted pair wire structures that are highly sensitive to position.
[0036] Preferably, a top wire roller 22 is also installed on the top of the top wire rod 2. This top wire roller 22 structure introduces an active rotating contact surface, significantly improving the contact flexibility and dynamic adaptability of the wire during the lifting process. Under the action of the top wire roller 22, the wire will not experience pulling or lateral wear as the top rod 2 is forcibly raised; instead, it reduces frictional resistance through rolling contact, thereby achieving a smooth transition in wire length adjustment and avoiding stress lock-in. Furthermore, the top wire roller 22 also possesses a certain vibration absorption and micro-buffering effect, which is particularly helpful in suppressing the accumulation of local vibrations at high-speed operating frequencies, improving the dynamic stability of the overall lifting system.
[0037] Preferably, the top wire rod 2 is in the form of a sheet or a column. The sheet configuration supports the wire with a narrow surface, resulting in a more refined point structure. The sheet configuration supports the wire with a wide surface, providing a larger wire contact area compared to a point-and-column structure. This disperses the force application points during lifting, preventing indentations or plastic deformation of the wire, and also facilitates the integrated molding and stiffness control of the top wire channel structure. More importantly, the sheet-shaped top wire rod 2 is structurally more suitable for applications with small gaps between high-density wire rows and compact wiring, especially facilitating the dense arrangement and coordinated control of multiple top wire rods 2 within a limited space.
[0038] Preferably, the system further includes at least one pressure block 4 and at least one pressure block driving device 5. The pressure block driving device 5 is connected to the pressure block and moves it to the base 1 on the upper side of the top rod guide opening 11. The introduction of the pressure block 4 in this solution achieves stable re-pressing of the wire after lifting. Its function is not only physical fixation, but also provides a buffering mechanism against wire rebound and displacement disturbances under dynamic working conditions. Its mobility, controlled by the driving device, allows it to automatically adjust the pressing stroke according to the actual lifting amplitude, thus forming a dynamic closed-loop control system. This achieves a two-way adjustment mechanism for wire length control: lifting and pressing. This enhances the structural consistency and processing tolerance compensation capability in the assembled state.
[0039] Preferably, the wire pressing block 4 is cylindrical. The cylindrical geometry offers one of the most uniform contact stress distributions, ensuring continuous axial pressure distribution rather than concentrated loading during wire pressing, thus avoiding the risk of core damage or sheath breakage. Simultaneously, the wire pressing groove 41 introduced on its surface forms a stable embedded guiding space. The groove structure provides a clear positioning range for the wire during pressing, preventing lateral displacement and ensuring that the wire forms a stable fixed point in three-dimensional space after lifting and adjustment. This, in turn, guarantees the parallelism of the wire ends and the coplanarity of the contact surfaces.
[0040] Preferably, the top wire rod drive device 3 and the pressure block drive device 5 are either cylinders or motors. Cylinders are suitable for automated production line scenarios with high frequency and high stroke repeatability, and have the advantages of rapid action and stable force output. Motor drives are suitable for complex wire adjustment tasks that require programmable control or multi-level actions. Their precise step distance and feedback control capabilities help to achieve quantitative control of wire lifting. Both are adapted to different production cycles and control accuracy requirements, and can be flexibly deployed according to actual applications, further improving the compatibility and operational reliability of the entire top wire pressing system.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
