Description

Technical Field

[0001] This utility model relates to the field of wire harness production technology, and in particular to a shielding mesh processing device based on scraper disintegration and an automatic wire harness assembly line. Background Technology

[0002] In wire harness manufacturing, the treatment of the shielding mesh is a crucial step in ensuring signal transmission stability and electromagnetic interference resistance. Current technology requires maintaining the integrity of the shielding mesh during disassembly to avoid cutting it, so that subsequent processing can form a grounding conductor. However, because the shielding mesh is usually woven from fine copper or alloy wires, excessive mechanical force can easily cause localized breakage, disrupting conductivity continuity and reducing grounding performance. Existing processes struggle to evenly disperse the shielding mesh without damaging its structure. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a shielding mesh processing device and an automatic wire harness assembly line based on a scraper-based dispersing method, which has the advantages of uniformly dispersing the shielding mesh wires and avoiding structural damage.

The scraping member includes a body and a scraper structure disposed on the body. Multiple scraper structures are arranged at intervals along the extension direction of the wire harness. The first driving member can drive the scraping member to move along the extension direction of the wire harness so that the scraper structure contacts the wire harness. The scraper structure can open the shielding layer of the wire harness and disperse the wires.

[0006] According to an embodiment of this utility model, a shielding mesh processing device based on scraper disintegration has at least the following beneficial effects: This application achieves non-destructive disintegration of the shielding layer through the synergistic action of the scraper structure and the driving mechanism in the wire harness disintegration device. The first driving member drives the scraper to move along the axial direction of the wire harness, causing the scraper structure and the wire harness to generate relative displacement, and gradually peeling off the shielding layer using the mechanical action of the scraper structure. The design of multiple scraper structures arranged at intervals along the axial extension direction of the wire harness can effectively improve the separation efficiency and separation effect, and can also play a sorting role in the shielding mesh during the continuous scraping movement. The scraper structure forms dynamic contact with the shielding layer during the movement, and opens the shielding layer through continuous scraping action rather than instantaneous impact force, which not only ensures that the copper wires of the shielding mesh are not cut, but also effectively separates the tangled wires. Among them, the body serves as the mounting base for the scraper structure, ensuring the synchronization and trajectory stability of each scraper during the movement process, further reducing the risk of local overload caused by component vibration.

[0007] According to an embodiment of the present invention, a shielding mesh processing device based on scraper disintegration is provided. The scraper structure consists of multiple scrapers arranged along the cross-sectional contour of the wire harness. The interval between two adjacent scrapers forms a partition groove, which can accommodate and separate the wires.

[0008] According to an embodiment of the present invention, a shielding mesh processing device based on scraper disintegration is provided. The scraper includes a blade body and a blade edge. The blade body is fixedly connected to the main body, and the blade edge is fixedly connected to the blade body. The blade edge can contact the wire harness to open the shielding layer of the wire harness.

[0010] or,

[0011] The blade has a conical structure, with the tip forming the cutting edge.

[0012] According to an embodiment of the present invention, a shielding mesh processing device based on scraper disintegration has a guide groove in its main body, a scraper structure disposed in the guide groove, and a first opening provided at one end of the guide groove facing the wire harness. The diameter of the first opening is greater than or equal to the maximum diameter of the wire harness, and the first opening allows the wire harness to enter the guide groove.

[0013] According to an embodiment of the present invention, a shielding mesh processing device based on scraper disintegration is provided. The wire harness disintegration device further includes a lifting mechanism. A first driving member is connected to the lifting mechanism, and the lifting mechanism can drive the scraper to move away from or closer to the wire harness.

[0014] According to an embodiment of the present invention, a shielding mesh processing device based on scraper dispersal includes a wire harness dispersal device further comprising a pressure sensor, which is disposed on the scraper and electrically connected to the lifting mechanism.

[0015] According to an embodiment of the present invention, a shielding mesh processing device based on scraper disintegration further includes a wire harness transport fixture for transporting the wire harness to be disintegrated to the wire harness disintegration device. A first clamping mechanism is provided at one end of the wire harness transport fixture near the end of the wire harness, and the first clamping mechanism is used to clamp and fix the end of the wire harness.

[0016] According to an embodiment of the present invention, a shielding mesh processing device based on scraping and breaking up includes a second clamping mechanism, which is arranged opposite to the first clamping mechanism, and the second clamping mechanism and the first clamping mechanism respectively clamp and fix the two ends of the wire harness segment to be broken up.

[0021] An automatic assembly line for wire harnesses according to an embodiment of the present utility model has at least the following beneficial effects:

[0022] This application achieves non-destructive dismantling of the shielding layer through the synergistic action of the scraper structure and drive mechanism in the wire harness dismantling device. The first drive unit drives the scraper to move along the axial direction of the wire harness, causing relative displacement between the scraper structure and the wire harness. The mechanical action of the scraper structure gradually peels off the shielding layer. The design of multiple scraper structures spaced apart along the axial extension direction of the wire harness effectively improves separation efficiency and effect. During movement, the scraper structure forms dynamic contact with the shielding layer, opening it through continuous scraping action rather than instantaneous impact force. This ensures that the copper wires of the shielding mesh are not cut while effectively separating the tangled wires. The main body serves as the mounting base for the scraper structure, ensuring the synchronization and trajectory stability of each scraper during movement, further reducing the risk of localized overload caused by component vibration.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] In existing technologies, the processing of the shielding mesh during wire harness manufacturing is a crucial step in ensuring signal transmission stability and electromagnetic interference resistance. Current technology requires maintaining the integrity of the shielding mesh during disassembly, avoiding cuts, to facilitate subsequent twisting to form a grounding conductor. However, because the shielding mesh is typically woven from fine copper or alloy wires, excessive mechanical force can easily cause localized breakage, disrupting conductive continuity and reducing grounding performance. Existing processes struggle to evenly disperse the shielding mesh without damaging its structure. For example, traditional equipment using a single tool for cutting or pulling can easily lead to broken copper wires in the shielding layer or localized stress concentration, affecting the quality of subsequent processing.

[0036] This application decomposes the mechanical action into multiple axially distributed scraping actions, and uses dynamic reciprocating motion to form a gradient force, thereby achieving conductor dispersion while maintaining the integrity of the shielding mesh.

[0037] Reference Figures 1 to 3 This utility model provides a shielding mesh processing device based on scraper disintegration, including a wire harness disintegration device.

[0038] Reference Figures 1 to 2 The wire harness dispersing device includes a first driving member (not shown) and a scraper 100. The scraper 100 is connected to the output end of the first driving member (not shown). The scraper 100 includes a body 110 and scraper structures disposed on the body 110, with multiple scraper structures arranged at intervals along the extension direction of the wire harness. The first driving member (not shown) can drive the scraper 100 to move along the extension direction of the wire harness, causing the scraper structures to contact the wire harness, thereby opening the shielding layer of the wire harness and dispersing the wires.

[0039] Understandably, after the wire harness is fixed, the scraper 100 abuts against the top of the wire harness's shielding layer. Subsequently, the first driving member (not shown) drives the scraper 100 to reciprocate along the axial direction, or the first driving member (not shown) drives the scraper 100 to perform repeated unidirectional movements along the axial direction. That is, the first driving member (not shown) drives the scraper 100 to continuously scrape against the shielding layer, so that the shielding layer is broken apart by the scraper 100. Alternatively, after the first driving member (not shown) drives the scraper 100 to complete a single unidirectional movement along the length of the wire harness, the scraper 100 detaches from the shielding layer and returns to its original position. The first driving member (not shown) then repeats the aforementioned steps to break apart the shielding layer.

[0040] Specifically, the scraper structure contacts the shielding layer surface during movement, gradually separating the tangled copper wires through continuous scraping. Furthermore, the design of multiple scraper structures spaced apart along the axial direction of the wire harness effectively improves separation efficiency and effect, and also helps to organize the shielding mesh during continuous scraping. The body 110 provides a stable mounting base for the scrapers 120, ensuring that each scraper 120 remains synchronized during movement. During this process, the scraper structure forms dynamic contact with the shielding layer during movement, achieving wire dispersion while maintaining the continuity of the shielding layer. The shielding layer is opened through continuous scraping action rather than instantaneous impact force, ensuring that the copper wires of the shielding mesh are not cut while effectively separating the tangled wires. This allows the shielding layer to open gradually, and the wires to be evenly dispersed under the separating action of the scrapers 120, while the copper wires are prevented from being cut due to the dynamic contact method.

[0041] According to some embodiments of this application, specifically, such as Figure 1As shown, the scraper structure consists of multiple scrapers 120, which are arranged along the cross-sectional profile of the wire harness. The interval between two adjacent scrapers 120 forms a partition groove, which is used to accommodate and separate the wires.

[0042] It is understood that the scraping component 100 of this application mainly consists of multiple matrix-distributed scrapers 120. Each scraper 120 acts independently on different areas of the shielding layer. The gaps between adjacent scrapers 120 are formed during the scraping process to separate the individual wires that have been scraped out, so as to physically isolate the wires.

[0043] Preferably, the scrapers 120 are arranged along the cross-sectional contour of the wire harness. It can be understood that the spatial layout of the scrapers 120 matches the shape of the wire harness. Specifically, they can be arranged in an arc or in a ring array to ensure that all directions of the outer surface of the wire harness are covered.

[0044] When the wire harness enters the scraper structure, multiple scrapers 120 arranged along its cross-sectional contour simultaneously contact the shielding layer. Each scraper 120 independently cuts into a different position of the shielding mesh. Due to the spacing between the scrapers 120 forming a dividing groove, the wire is automatically guided into the corresponding groove during the movement of the scraper 120. The separation effect between adjacent scrapers 120 ensures that the wire maintains a distance during the unfolding process, avoiding mutual entanglement and the generation of local stress.

[0045] In addition, the arrangement of the cross-sectional contours allows the 120 sets of scrapers to form an enclosing structure, enabling the cutting of the full circumferential shielding layer to be completed in a single scraping motion without the need to adjust the wire harness angle.

[0046] That is, such as Figure 1 and Figure 2As shown, the scraper 100 is provided with a guide groove 111, and a scraper structure is disposed within the guide groove 111. The end of the guide groove 111 facing the wire harness has a first opening, the diameter of which is greater than or equal to the maximum diameter of the wire harness, allowing the wire harness to enter the guide groove 111. It can be understood that the scraper 100 is provided with a U-shaped or semi-circular cross-section groove to constrain the direction of the wire harness entry and limit the movement trajectory of the scraper structure. When the wire harness enters the guide groove 111 through the first opening, a clearance fit is formed between the wire harness skin and the edge of the opening because the opening diameter is adapted to the maximum outer diameter of the wire harness, avoiding contact friction that could cause pre-damage to the shielding layer. The inner wall of the guide groove 111 forms a circumferential wrap around the wire harness. When the scraper structure moves within the groove, the cutting angle of the blade 122 contacting the wire harness shielding layer is limited by the groove wall, ensuring that the scraper 120 only cuts the shielding layer along a predetermined path, preventing localized stress concentration due to trajectory deviation. After the wires are separated by the scraper 120, their lateral displacement is blocked by the sidewall of the guide groove 111, thereby maintaining the stability of the dispersed state. This application, through the cooperation of the guide groove 111 and the first opening, ensures that the wire harness accurately enters the guide groove 111 without external pressure. The shielding layer is uniformly cut by the scraper 120 along a predetermined trajectory, and the dispersed wires are constrained by the groove wall to maintain a stable arrangement. This solves the problems of positioning offset and mechanical pressure damage caused by mismatched entrance dimensions, improving the reliability of the shielding mesh disintegration process and the uniformity of wire dispersion.

[0047] Optionally, the feed end of the first opening may be provided with a chamfer to serve as a guide interface for the wire harness to enter the guide groove 111, so as to guide the wire harness smoothly into the guide groove 111 without radial compression.

[0048] This application utilizes a discrete scraper 120 layout to decompose the cutting action into multiple independent points of application, distributing the force throughout the entire circumference of the wire harness. Simultaneously, the separator groove physically isolates the wires while unfolding the shielding layer, and simultaneously organizes the wires, achieving integrated cutting and wire separation operations. This avoids secondary damage caused by wire entanglement during subsequent processing. The matching layout of the scraper 120 set with the wire harness shape ensures that full circumferential processing can be completed in a single operation, eliminating the risk of repeated work due to missed areas.

[0049] According to some embodiments of this application, the scraper 120 includes a blade body 121 and a blade 122. The blade body 121 is fixedly connected to the body 110, and the blade 122 is fixedly connected to the blade body 121. The blade 122 can contact the wire harness to open the shielding layer of the wire harness.

[0050] Specifically, this application provides a first embodiment of a scraper 120. For example... Figure 2As shown, the blade body 121 adopts a conical structure with a cutting edge 122 formed at its tip; that is, the scraper 120 is a conical structure overall. When the conical cutting edge 122 contacts the shielding layer, its tapered geometry allows the cutting force to be applied gradually along the axial direction, avoiding instantaneous concentrated load that could cause copper wire breakage. During the cutting process of the tip of the conical blade body 121 into the shielding layer, the lateral force is dispersed by the conical sidewall, reducing the risk of compression deformation of the conductor bundle. Furthermore, the conical scraper 120 has an arc-shaped outer wall, which can prevent damage to the conductor when the scraper 120 contacts the shielding layer conductor.

[0051] Alternatively, in some other embodiments of this application, the blade body 121 is a cylindrical structure or other columnar structure, and a conical blade 122 is fixedly connected to the blade body 121.

[0052] In the above embodiments, the cutting action of the scraper 120 is completed by progressively penetrating the shielding layer, rather than the shearing method of the traditional right-angle blade 122. Through the geometric optimization of the conical structure, the cutting method is transformed into progressive penetration, thereby maintaining the integrity of the shielding mesh structure while opening the shielding layer and maintaining the continuous connection between the copper wires. This effectively solves the problem of copper wire breakage caused by excessive mechanical force during the disintegration of the shielding mesh, ensuring that the shielding layer is evenly dispersed while maintaining the continuity of the conductive path. It can be understood that the conical blade 122 or blade body 121 structure of this application, while achieving effective cutting, significantly reduces the probability of copper wire damage by reducing the contact area and dispersing force, meeting the process requirements for the integrity of the shielding mesh in subsequent grounding wire processing.

[0053] According to some embodiments of this application, the wire harness disintegration device further includes a lifting mechanism (not shown in the figure), a first driving member (not shown in the figure) is connected to the lifting mechanism, and the lifting mechanism (not shown in the figure) can drive the scraping member 100 away from or near the wire harness.

[0054] Understandably, the lifting mechanism (not shown) drives the scraper 100 to move vertically by receiving external control signals, so that the contact pressure between the scraper structure and the wire harness is adjusted in real time according to the wire harness diameter and the shielding layer thickness. When the wire harness enters the guide groove 111, the lifting mechanism drives the scraper 100 to press down to the preset initial position. At this time, the scraper structure contacts the surface of the shielding layer with constant pressure. During the horizontal movement of the scraper structure driven by the first driving member (not shown), the lifting mechanism can drive the scraper 120 to continuously increase the amount of intrusion into the shielding layer, so as to improve the scraping depth of the shielding layer and achieve the purpose of dispersing the shielding layer.

[0055] Furthermore, the wire harness dispersing device also includes a pressure sensor (not shown in the figure), which is mounted on the dispersing component 100 and electrically connected to the lifting mechanism (not shown in the figure). If abnormal local resistance is detected, the lifting mechanism can immediately raise the dispersing component 100 to reduce the cutting depth, avoiding copper wire breakage due to pressure concentration. This effectively prevents the shielding mesh copper wire from breaking due to excessive force applied by the scraper 120, ensuring that the shielding layer is opened evenly and the contact pressure is stable during the wire dispersion process.

[0056] This application utilizes coordinated control of vertical and horizontal movements, enabling the scraper 120 to effectively strip the shielding layer while maintaining the integrity of the copper wire structure during conductor dispersion.

[0057] According to some embodiments of this application, this application also includes a wire harness transport fixture 200 for transporting the wire harness to be unpacked to the wire harness unpacking device, so as to further improve the degree of automation. Specifically, a first clamping mechanism 210 is provided at one end of the wire harness transport fixture 200 near the end of the wire harness. The first clamping mechanism 210 is used to clamp and fix the end of the wire harness to prevent the wire harness from axially shifting or circumferentially deflecting during the unpacking process.

[0058] Furthermore, the wire harness disintegration device is also equipped with a second clamping mechanism (not shown in the figure). The second clamping mechanism (not shown in the figure) is arranged opposite to the first clamping mechanism 210, and the second clamping mechanism (not shown in the figure) and the first clamping mechanism 210 respectively clamp and fix the two ends of the wire harness segment to be disintegrated. It can be understood that the first clamping mechanism 210 and the second clamping mechanism (not shown in the figure) form a tension device. By clamping and fixing the two ends of the wire harness segment to be disintegrated by the first clamping mechanism 210 and the second clamping mechanism (not shown in the figure), the wire harness segment is kept in a taut state. When the scraper structure moves along the extension direction, the wire harness cannot slide longitudinally because the two ends are fixed. The shielding layer is cut evenly without the copper wire breaking due to excessive local stress. At the same time, after the wire harness is constrained circumferentially, the cutting angle of the scraper 120 remains stable, avoiding incomplete disintegration of the shielding mesh due to wire harness twisting.

[0059] Preferably, the clamping position of the second clamping mechanism (not shown) is adjustable, for example, by changing the distance between it and the first clamping mechanism 210 through a slide rail mechanism, to accommodate wire harness segments of different lengths.

[0060] According to some embodiments of this application, a debris cleaning device (not shown in the figure) is also provided.

[0061] In a first embodiment of the debris removal device (not shown), the device includes an air blowing mechanism capable of delivering airflow toward the wire harness to be broken up. This mechanism removes debris generated during the breaking up of the wire harness. Specifically, the debris removal device may employ an air pump and an adjustable-angle nozzle. Compressed air output from the air pump forms a high-speed airflow through the nozzle, impacting the surface of the wire harness. Debris is detached from the wire harness surface under the impact of the airflow and discharged along the airflow direction, thus removing debris. This non-contact cleaning method avoids secondary damage to the shielding layer.

[0062] In a second embodiment of the debris removal device (not shown), the device includes an electrostatic adsorption mechanism capable of removing debris generated during the disassembly of the wire harness. Specifically, the debris removal device can be implemented using a combination of a high-voltage generator and a dust collection plate. The high-voltage generator creates a strong electric field around the dust collection plate, causing metal debris to become charged and adsorbed onto the surface of the dust collection plate. Efficient cleaning is achieved through the active capture of particulate debris. It is understood that the high-voltage generator creates an electric field between the dust collection plate and the wire harness. Metal debris becomes charged in the electric field and is adsorbed onto the dust collection plate. Debris collection is achieved through periodic cleaning of the dust collection plate, without direct contact with the wire harness, thus avoiding scratching the shielding layer or wires.

[0063] This application also provides an automatic wire harness assembly line (not shown in the figure) that uses the above-mentioned shielding mesh processing equipment, which can effectively improve the disintegration efficiency and disintegration effect of the wire harness shielding mesh and realize the automation of shielding mesh disintegration.
