A method for processing wire harness shielding mesh

Abstract

This invention provides a method for processing wire harness shielding mesh, relating to the field of wire harness processing equipment. After pre-processing the wire harness, a limiting device is used to limit both ends of the portion of the wire harness to be processed (at least one limiting point is provided at each end of the portion to be processed). Then, the shielding mesh of the portion to be processed is processed accordingly. That is, this method uses the "limiting at both ends" method to form a double constraint on the wire harness in both the axial and radial directions, effectively avoiding the wire harness from sliding or rotating during the shielding mesh processing (such as disintegration, folding, ring pressing, etc.), greatly enhancing the stability of the wire harness during the shielding mesh processing and ensuring the processing quality.

Technical Field

[0001] This application relates to the field of wire harness processing equipment, and in particular to a method for processing wire harness shielding mesh. Background Technology

[0002] With economic development and social progress, the new energy vehicle market is gradually expanding. The demand for shielded wire harnesses is also increasing, leading to a growing demand for automated processing of these harnesses upstream. The processing of shielding mesh has become one of the core processes in the manufacturing of these wire harnesses.

[0003] Currently, the processing of wire harness shielding mesh typically involves pre-treatment methods such as peeling to expose the shielding layer and create the area to be processed, followed by a series of related processing steps such as breaking up and flipping the mesh. However, existing shielding mesh processing procedures only limit the position of one end of the area to be processed. For wire harnesses that are soft or too long, the existing processing methods cannot guarantee the stability of the wire harness, affecting the processing quality. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a wire harness shielding mesh processing method to solve the problem that existing wire harness shielding mesh processing methods are unable to guarantee the stability of the wire harness, thereby affecting the processing quality.

[0005] To achieve the above objectives, the present invention provides a method for processing wire harness shielding mesh, wherein the method includes the following steps: S10: Pre-process the wire harness so that the first end of the wire harness forms a part to be processed; S20: The wire harness is limited by a limiting device, and at least one limiting point is provided at each end of the part to be processed along the length direction of the wire harness; S30: Process the part to be processed at the first end of the wire harness.

[0006] Preferably, the wire harness is provided with an inner wire body, a shielding mesh layer, and an outer wire body; Step S10 specifically includes the following steps: S110: Strip the outer layer of the wire at the first end of the wire harness so that the shielding mesh layer at the first end of the wire harness is exposed; S120: Cut off the exposed shielding mesh of the shielding layer, and expose the inner wire of the first end of the wire harness.

[0007] Preferably, step S20 specifically includes the following steps: S210: The outer layer of the second end of the part to be processed is limited by the limiting device; S220: The inner layer of the first end of the part to be processed is limited by the limiting device.

[0008] Preferably, the limiting device includes a base, and a first clamping mechanism and a second clamping mechanism are provided on the top of the base. The first clamping mechanism is used to clamp a first end of the wire harness, and the second clamping mechanism is used to clamp a second end of the wire harness.

[0009] Preferably, the first clamping mechanism is movably connected to the base via a movable component, and the movable component can drive the first clamping mechanism to reciprocate along a first direction; the first clamping mechanism and the second clamping mechanism are distributed at intervals along the first direction.

[0010] Preferably, the first clamping mechanism includes a gripper assembly, which is connected to the moving assembly via a lifting assembly, and the lifting assembly can drive the gripper assembly to reciprocate in the vertical direction; The gripper assembly includes two first grippers, which are spaced apart along a second direction and are capable of reciprocating along the second direction to clamp or release the wire harness. The first direction, the second direction, and the vertical direction are perpendicular to each other.

[0011] Preferably, the second clamping mechanism includes two second jaws that can rotate synchronously to clamp or release the wire harness; the rotation axes of the two second jaws extend along the first direction.

[0012] Preferably, in step S30, the shielding mesh of the wire harness is processed by a processing device.

[0013] Preferably, the limiting device is assembled with the processing device to form a processing equipment.

[0014] Preferably, the processing device further includes a controller for controlling the processing unit and the limiting device.

[0015] According to the wire harness shielding mesh processing method of the present invention, after the wire harness is pre-processed, the two ends of the part to be processed of the wire harness are limited by a limiting device (at least one limiting point is provided at each end of the part to be processed), and then the shielding mesh of the part to be processed is processed accordingly. That is, the method adopts the "two-end limiting" method to form a double constraint on the wire harness in the axial and radial directions, which effectively avoids the wire harness from sliding or rotating during the shielding mesh processing (e.g., breaking apart, folding, ring pressing, etc.), greatly enhances the stability of the wire harness during the shielding mesh processing, and ensures the processing quality.

[0020] The following detailed embodiments are provided to help the reader gain a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0021] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0022] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0023] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0024] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0025] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

For example, if the device in the drawings is flipped, an element described as being “above” or “upper” relative to another element will subsequently be “below” or “lower” relative to that other element. Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0027] Variations in the shapes shown in the accompanying drawings may occur due to manufacturing techniques and / or tolerances. Therefore, the examples described herein are not limited to the specific shapes shown in the accompanying drawings, but include changes in shape that may occur during manufacturing.

[0028] The features of the examples described herein can be combined in various ways that will be apparent upon understanding the disclosure of this application. Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0029] This invention provides a method for processing wire harness shielding mesh, such as... Figure 1 As shown, the wire harness shielding mesh processing method (hereinafter referred to as the processing method) includes the following steps: S10: Pre-process the wire harness so that the first end of the wire harness forms a part to be processed; S20: The wire harness is limited by the limiting device 1, and at least one limiting point is provided at each end of the part to be processed along the length direction of the wire harness. S30: The part to be processed at the first end of the wire harness.

[0030] Thus, during the processing of the wire harness shielding mesh, the limiting device 1 can form a double constraint on the wire harness in the axial and radial directions by "limiting at both ends", which effectively avoids the wire harness from sliding or rotating during the shielding mesh processing (such as disassembly, folding, and ring pressing), greatly enhancing the stability of the wire harness during the shielding mesh processing and ensuring the processing quality.

[0031] The wire harness is defined to have an inner wire body, a shielding mesh, and an outer wire body. Based on this, step S10 specifically includes the following steps: S110: Strip the outer layer of wires from the first end of the wire harness to expose the shielding mesh layer at the first end of the wire harness; S120: Cut off the exposed shielding mesh to expose the inner wire of the first end of the wire harness.

[0032] The removal of the outer layer of wire from the first end of the wire harness and the cutting off of the exposed shielding mesh can be performed using existing equipment, which is prior art and will not be described in detail here. Furthermore, in step S120, cutting the shielding mesh means cutting off the free end of the shielding mesh to facilitate clamping by the limiting device 1. In other words, the exposed shielding mesh layer at the first end of the wire harness is the part of the wire harness to be processed. It should be noted that the specific structure of the wire harness is not limited. The phrase "the wire harness is provided with an inner layer of wire, a shielding mesh, and an outer layer of wire" simply divides the wire harness into three parts. For example, the inner layer of wire, the shielding mesh layer, and the outer layer of wire can be distributed radially along the wire harness in a layered, overlapping structure. The shielding mesh layer uniformly covers the outer part of the inner layer of wire along the circumference of the wire harness; alternatively, the shielding mesh can be twisted into one or more strands to serve as a shielding mesh layer.

[0033] Furthermore, step S20 specifically includes the following steps: S210: The outer layer of the second end of the treatment section is limited by the limiting device 1; S220: The inner layer of the first end of the treatment section is limited by the limiting device 1.

[0034] Therefore, in this processing method, the limiting points of the limiting device 1 on the wire harness are the outer and inner wire bodies, that is, the wire harness is limited by a "layered limiting" method. This can prevent the limiting force from acting directly on the shielding mesh or the conductor core inside the wire harness. Limiting the inner wire body of the wire harness can fix the relative position of the conductor core and the inner sheath, while limiting the outer wire body of the wire harness can ensure the overall stability of the wire harness. The two work together to prevent the conductor core inside the wire harness from being stretched or squeezed when processing the shielding mesh, thereby effectively reducing the risk of damage to the signal transmission performance of the wire harness. Depending on the type of wire harness, the specific structural layers of the inner and outer wire bodies of the wire harness are different. That is, there is no restriction on the specific limiting points of the limiting device 1 along the radial direction of the wire harness. For example, the inner wire body of the wire harness includes a conductor core layer, an inner sheath layer, and an aluminum foil layer from the inside to the outside. The limiting device 1 can be connected to the inner sheath layer or the aluminum foil layer, as long as the above technical effect can be achieved.

[0035] In this embodiment, as Figure 2 As shown, the limiting device 1 includes a base 11, which is formed into a double-layer structure to facilitate fixing the wire harness to a height that is easy to handle. A first clamping mechanism 13 and a second clamping mechanism 15 are provided on the top of the base 11, both of which are aligned along a first direction (i.e., Figure 2 The wire harness is distributed at intervals in the X direction. The first clamping mechanism 13 is used to clamp the first end of the wire harness, and the second clamping mechanism 15 is used to clamp the second end of the wire harness.

[0036] Specifically, the first clamping mechanism 13 is movably connected to the base 11 via a movable component 12. The movable component 12 drives the first clamping mechanism 13 to reciprocate along a first direction, thus allowing the limiting device 1 to flexibly adjust the specific limiting points on the wire harness according to actual conditions (such as the length and type of the wire harness, the specific processing steps for the wire harness shielding mesh, etc.), i.e., the distance between the two limiting points of the wire harness is adjustable. The specific structure of the movable component 12 is not limited. For example, in this embodiment, the movable component 12 is assembled from a drive motor, a lead screw assembly, etc., or it can be driven by a cylinder to drive the first clamping mechanism 13 to reciprocate. This is a conventional technical means in the mechanical field, so it will not be described in detail. As long as the above technical effect can be achieved, it is acceptable.

[0037] More specifically, such as Figure 2 As shown, the first clamping mechanism 13 includes a lifting assembly 131 and a gripper assembly, which are integrated by a support plate. The support plate is fixedly connected to the moving end of the aforementioned moving assembly 12. The lifting assembly 131 is disposed at the top of the support plate, and the gripper assembly is correspondingly connected to the lifting end of the lifting assembly 131. Thus, the lifting assembly 131 can drive the gripper assembly to reciprocate vertically, thereby avoiding interference with handling mechanisms during processes such as wire harness transfer, and increasing the flexibility of the limiting device 1 to adapt to different processing devices. Further, the gripper assembly includes two first grippers 132, which move along a second direction (i.e.,... Figure 2 The two first grippers 132 are spaced apart in the Y direction and can reciprocate along the second direction to clamp or release the wire harness.

[0038] It should be noted that the specific structure of the lifting assembly 131 is not limited; for example, it can be an assembly structure of cylinder, slide rail, and slider. Similarly, the structure of the assembly that drives the first gripper 132 to move is also not limited; for example, it can be a structure of drive motor, slide rail, and slider. All of the above components belong to existing mechanical structures, and therefore will not be described in detail. It should be further noted that the first direction, the second direction, and the vertical direction are perpendicular to each other.

[0039] In this embodiment, the second clamping mechanism 15 includes two second grippers 151, which can rotate synchronously to clamp or release the wire harness; the rotation axes of the two second grippers 151 extend along a first direction. The second clamping mechanism 15 itself is an existing mechanism, and its structure and principle will not be described in detail.

[0040] Preferably, the second clamping mechanism 15 can also be movably connected to the base 11 through a mechanism similar to that of the moving component 12, thereby enabling both the first clamping mechanism 13 and the second clamping mechanism 15 to reciprocate, resulting in greater flexibility and a wider range of applications. For example, for a wire harness with a relatively long section to be processed, the section to be processed (along the length direction of the wire harness) can be divided into multiple sub-regions. The movable first clamping mechanism 13 and the second clamping mechanism 15 can clamp the two ends of the sub-regions respectively, and process each sub-region sequentially.

[0041] Alternatively, a conventional wire harness limiting device can be used to fix the wire harness, as long as the stability of the part of the wire harness to be processed can be guaranteed.

[0042] It should be noted that in this embodiment, the two first jaws 132 of the first clamping mechanism 13 clamp or release the wire harness by reciprocating movement. During clamping, the stroke is long and the clamping force is large (mainly the radial clamping force of the wire harness), thus providing stable and symmetrical radial pressure. This allows for a firm gripping of the first end of the wire harness to resist axial tension or torsion, facilitating the processing of the shielding mesh at the first end of the wire harness. Furthermore, in this embodiment, the two second jaws 151 of the second clamping mechanism 15 clamp or release the wire harness by rotation. This clamping method is relatively gentle and can accommodate slight swaying at the second end of the wire harness, avoiding stress concentration caused by rigid constraints at both ends of the wire harness.

[0043] Additionally, in step S30, the shielding mesh of the wire harness is processed by a processing device. The specific structure of this processing device is not limited; for example, depending on the shielding mesh processing steps, the processing device can be configured as a separation device 2 capable of breaking down the shielding mesh (e.g., Figure 3 As shown), it can also be configured as a tightening device capable of tightening the shielding mesh. Further, the aforementioned limiting device 1 is assembled correspondingly with the processing device to form a corresponding processing equipment. For example, when the separating device 2 is assembled correspondingly with the limiting device 1, the processing equipment is configured as a separating processing equipment for the real-time disintegration process of the shielding mesh (such as...). Figure 4 (As shown). In addition, the processing equipment also includes a controller 3 for controlling the corresponding actions of the processing device and the limit device 1.

[0044] According to the wire harness shielding mesh processing method of the present invention, after the wire harness is pre-processed, the two ends of the part to be processed of the wire harness are limited by the limiting device 1 (at least one limiting point is provided at each end of the part to be processed), and then the shielding mesh of the part to be processed is processed accordingly. That is, the method adopts the "two-end limiting" method to form a double constraint on the wire harness in the axial and radial directions, which effectively avoids the wire harness from sliding or rotating during the shielding mesh processing (e.g., breaking apart, folding, ring pressing, etc.), greatly enhances the stability of the wire harness during the shielding mesh processing, and ensures the processing quality.
