[0002] In wire harness manufacturing, the processing of the shielding mesh is a crucial step in ensuring stable signal transmission and strong resistance to electromagnetic interference. Current technology requires maintaining the integrity of the shielding wires during the disassembly of the mesh to prevent them from being cut, so that a grounding conductor can be formed in subsequent processing. However, since the shielding mesh is usually woven from fine copper or alloy wires, excessive mechanical force can easily cause localized breakage, disrupting the conductive continuity of the mesh and reducing its grounding performance. Existing processes struggle to uniformly disperse the shielding mesh without damaging its structure. Utility Model Content

In the description of this utility model, unless otherwise stated, "several" means one or more, and "multiple" means two or more.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0028] The following is for reference. Figures 1 to 3 This invention describes a shielding mesh processing device and an automatic wire harness assembly line based on ultrasonic vibration disintegration, according to embodiments of the present invention.
[0029] like Figures 1 to 3 As shown, the shielding mesh processing device based on ultrasonic vibration disintegration according to the first aspect of this utility model can be applied to an automatic wire harness assembly line and used to disintegrate the shielding mesh 410 on the wire harness 400. Furthermore, the shielding mesh processing device based on ultrasonic vibration disintegration of this embodiment can utilize ultrasonic oscillation energy to apply a gentle disintegration effect to the shielding mesh 410, avoiding damage to the structure of the shielding mesh 410 and affecting its conductive continuity, thereby ensuring that the shielding mesh 410 has the advantage of excellent grounding performance.
[0030] The shielding mesh disintegration equipment based on ultrasonic vibration includes a transport fixture 200 and an ultrasonic vibration device 100.
[0031] The transport fixture 200 includes a support portion and a clamping portion 210. The support portion supports the wire harness 400, and the clamping portion 210 secures the ends of the wire harness 400. It is understood that the support portion provides the necessary placement slots for the wire harness 400, allowing the long wire harness 400 to be placed on the support portion in a coiled manner, saving space. When it is necessary to unpack the shielding mesh 410 located at one end of the wire harness 400, the clamping portion 210 clamps and secures that end of the wire harness 400; when it is necessary to unpack the shielding mesh 410 located at both ends of the wire harness 400, the clamping portion 210 clamps and secures both ends of the wire harness 400. The specific structure of the support portion and the clamping portion 210 is not limited, as long as they satisfy the above functions.
[0032] For example, the clamping part 210 may include two hinged jaws that can be brought together by non-human external force such as magnetic force or torsion spring force, so that the two jaws can firmly clamp the outer insulation layer of the wire harness 400.
[0033] Before disassembling the shielding mesh 410, the ends of the wire harness 400 undergo a stripping process of the outer insulation layer, exposing part of the shielding mesh 410 structure on the wire harness 400. The clamping part 210 provides a stable clamping action on the ends of the wire harness 400, ensuring the shielding mesh 410 at the ends of the wire harness 400 remains stable and facilitates subsequent disassembly. In this embodiment, after the ends of the wire harness 400 are clamped and fixed, the ends of the wire harness 400 are horizontally positioned; specifically, the ends of the wire harness 400 extend in the left-right direction, such as... Figure 1 and Figure 2 As shown.
[0034] The ultrasonic vibration device 100 is equipped with a processing station, wherein a transport fixture 200 is configured to engage or disengage from the processing station. It is understood that the transport fixture 200 can be manually transferred to the processing station of the ultrasonic vibration device 100, or it can be transferred to the processing station via a conveyor or a handling robot, allowing the transport fixture 200 to engage with the processing station to complete the loading process. Alternatively, the unloading process can be completed manually or automatically, allowing the transport fixture 200 to disengage from the processing station.
[0035] The ultrasonic vibration device 100 is configured to apply ultrasonic oscillation energy to the shielding mesh 410 of the wire harness 400 on the transport fixture 200, thereby breaking up the shielding mesh 410 located at the end of the wire harness 400. Specifically, the ultrasonic vibration device 100 includes an ultrasonic transducer 110, which is positioned opposite to the processing station. The ultrasonic transducer 110 mainly consists of an ultrasonic transducer and an amplitude transformer. The ultrasonic transducer converts electrical energy into high-frequency mechanical vibration through the piezoelectric effect, and then amplifies the amplitude through the amplitude transformer before outputting ultrasonic oscillation energy. The ultrasonic transducer 110 can contact the shielding mesh 410 at the end of the wire harness 400 to transfer the ultrasonic oscillation energy to the shielding mesh 410. Of course, in other embodiments, it is not excluded that the ultrasonic transducer 110 and the shielding mesh 410 are not in contact, and the ultrasonic oscillation energy output by the ultrasonic transducer 110 is transferred to the shielding mesh 410 through the air medium.
[0036] When the transport fixture 200 carrying the wire harness 400 is transferred to the processing station, the ultrasonic vibration device 100 is activated. The ultrasonic vibration device 100 can output ultrasonic oscillation energy towards the wire harness 400 on the transport fixture 200, so that the ultrasonic oscillation energy can act on the shielding mesh 410 to be broken up on the wire harness 400. When the shielding mesh 410 is subjected to strong ultrasonic vibration, friction separation will occur between the shielding wires made of metal, causing the shielding mesh 410 (a structure woven from multiple shielding wires) to loosen naturally due to the high-frequency vibration effect, thereby completing the work of breaking up the shielding mesh 410.
[0037] Understandably, compared to existing mechanical stripping and brushing methods for dismantling the shielding mesh 410, the non-hard cutting dismantling method adopted in this embodiment is gentler on the shielding mesh 410, does not completely sever the shielding wires, and has no heat impact, preventing the shielding mesh 410 from altering its metallic properties due to high temperatures. Therefore, after the shielding mesh 410 is dismantled by ultrasonic vibration, the shielding wires exhibit good structural integrity, excellent conductivity continuity, and superior grounding performance.
[0038] In this embodiment, the ultrasonic transducer 110 is configured to move relative to the transport fixture 200 located at the processing station, so that the ultrasonic transducer 110 makes conformal contact with the shielding mesh 410, allowing the ultrasonic oscillation energy generated by the ultrasonic transducer 110 to act directly on the shielding mesh 410, making the shielding mesh 410 easier and faster to break apart, and reducing the loss of ultrasonic oscillation energy, thus saving energy consumption.
[0039] Understandably, the surface of the ultrasonic transducer 110 that contacts the shielding mesh 410 located at the end of the wire harness 400 is adapted to the shielding mesh 410. Specifically, the active surface of the ultrasonic transducer 110 can be concave arc-shaped to match the shape of the end of the wire harness 400 and can directly contact the shielding mesh 410. The central angle of the active surface of the ultrasonic vibration is less than or equal to 180°.
[0040] In some examples, the transport fixture 200 carries the wire harness 400 and is transferred to the processing station. At this time, the ultrasonic transducer 110 can move vertically or horizontally, allowing it to contact the exposed shielding mesh 410 on the wire harness 400. In other examples, the ultrasonic transducer 110 is positioned opposite the processing station. After the transport fixture 200 is transferred to the processing station, a drive device moves the transport fixture 200 vertically or horizontally, allowing the exposed shielding mesh 410 on the wire harness 400 to directly contact the ultrasonic transducer 110.
[0041] In this embodiment, the ultrasonic transducer 110 is located above the processing station. After the transport fixture 200 with the wire harness 400 is accurately transferred to the processing station, the ultrasonic transducer 110 is located above the transport fixture 200 and has a certain vertical distance from the shielding mesh 410 of the wire harness 400.
[0042] The ultrasonic vibration device 100 also includes a motion mechanism 120, wherein the movable end of the motion mechanism 120 is connected to the ultrasonic transducer 110. The motion mechanism 120 can be a linear drive device such as a cylinder, electric cylinder, or linear module, and is configured to drive the ultrasonic transducer 110 to move in the vertical direction. Through the driving action of the motion mechanism 120, the ultrasonic transducer 110 can move downward a certain distance so that the ultrasonic transducer 110 can come into contact with the shielding mesh 410, allowing the ultrasonic oscillation energy output by the ultrasonic transducer 110 to be directly transferred to the shielding mesh 410.
[0043] In the process of using the shielding mesh processing equipment based on ultrasonic vibration disintegration according to the present invention, when the transport fixture 200 carrying the wire harness 400 is transferred from the upstream station to the processing station of the ultrasonic vibration device 100, the ultrasonic vibration device 100 can output appropriate ultrasonic oscillation energy and apply the generated ultrasonic oscillation energy to the shielding mesh 410 located at the end of the wire harness 400, causing the shielding wires in the shielding mesh 410 to easily separate due to friction, so that the woven shielding mesh 410 is easily loosened naturally due to vibration, thereby completing the uniform disintegration of the shielding mesh 410 and ensuring that the structure of the shielding mesh 410 is not damaged.
[0044] In this embodiment, the ultrasonic vibration disintegration method described above is used to process the shielding mesh 410 very gently, which can avoid structural damage such as the shielding wire being cut or its metallic properties changing due to high temperature. This effectively ensures the good conductivity continuity of the shielding mesh 410, allowing the shielding mesh 410 on the wire harness 400 to perform excellent grounding performance. At the same time, it can also protect the internal conductors of the wire harness 400 from damage.
[0045] In some embodiments, such as Figure 1 and Figure 3 As shown, the ultrasonic vibration device 100 also includes a real-time monitoring unit. The real-time monitoring unit is electrically connected to the ultrasonic transducer 110 via a circuit. The real-time monitoring unit is configured to adjust the power of the ultrasonic transducer 110 through force feedback or impedance analysis to prevent excessive vibration of the shielding mesh 410, which could easily damage its structure.
[0046] In one specific embodiment, the real-time monitoring unit includes a pressure sensor configured to detect the pressure exerted by the ultrasonic transducer 110 on the shielding mesh 410. By monitoring the pressure exerted by the ultrasonic transducer 110 on the shielding mesh 410 in real time using the pressure sensor, when the detected pressure exceeds a set pressure threshold, the real-time monitoring unit automatically reduces the output power of the ultrasonic transducer 110 to prevent damage to the shielding mesh 410 or even pressure damage to the internal conductors of the wiring harness 400.
[0047] In one specific embodiment, the real-time monitoring unit includes an impedance analyzer electrically connected to the ultrasonic transducer 110, and the impedance analyzer is configured to detect the impedance value of the ultrasonic transducer 110.
[0048] Specifically, the ultrasonic vibration device 100 also includes a signal generator and a power amplifier. The output of the signal generator is electrically connected to the input of the power amplifier, and the output of the power amplifier is electrically connected to the input of an impedance analyzer. The impedance analyzer is bidirectionally electrically connected to the ultrasonic transducer, enabling bidirectional signal interaction between the two. The signal generator produces an electrical signal of a specific frequency, and the power amplifier amplifies the electrical signal output by the signal generator to provide a high-voltage electrical signal capable of driving the ultrasonic transducer. The ultrasonic transducer converts the amplified electrical signal into mechanical vibration based on the piezoelectric effect, thereby generating ultrasonic oscillation energy.
[0049] The impedance analyzer can dynamically monitor the impedance characteristics of the ultrasonic transducer. It primarily identifies series and parallel resonant points by scanning the impedance-frequency curve. Furthermore, the impedance analyzer can feed back the resonant frequency data to the signal generator, enabling automatic frequency tracking and compensation. The impedance analyzer monitors the resonant state of the ultrasonic transducer in real time, triggering the signal generator to dynamically adjust the output frequency, ensuring that the ultrasonic vibration device 100 always operates at the optimal resonant point. Moreover, through impedance matching, the output impedance of the signal generator matches the input impedance of the ultrasonic transducer, reducing signal reflection and ensuring maximum power transmission to the load, such as the shielding mesh 410. This allows for adjustment of the power of the ultrasonic vibration device 100.
[0050] In some embodiments, the shielding mesh processing equipment based on ultrasonic vibration disintegration further includes a conveying mechanism configured to deliver the transport fixture 200 to or from the processing station. The conveying mechanism may be a belt conveyor or a double-speed chain conveyor, etc.
[0051] In this embodiment, the conveying mechanism has a conveying plane 300, which extends in the left-right direction, such as... Figure 1 As shown, the conveying mechanism is a double-belt conveyor. The conveying mechanism automatically transports the transport fixture 200 along with the wire harness 400 to the processing station, where the shielding mesh 410 is dismantled using ultrasonic vibration. After dismantling the shielding mesh 410, the conveying mechanism transports the transport fixture 200 and the wire harness 400 out of the processing station.
[0052] In this embodiment, as Figure 1 and Figure 2 As shown, the clamping part 210 is located outside the bearing part, so that the end of the wire harness 400 is in a suspended state. It can be understood that by setting the clamping part 210 outside the bearing part, the end of the wire harness 400 can extend horizontally outside the bearing part and be firmly fixed by the clamping part 210. At this time, the shielding mesh 410 at one end of the wire harness 400 is exposed and suspended. By applying ultrasonic oscillation energy to the shielding mesh 410 through the ultrasonic transducer 110, the shielding mesh 410 can be automatically loosened and drooped under the action of ultrasonic vibration and gravity, which is convenient for subsequent processing to form a grounding wire by a knob.
[0053] In some embodiments, a carrier portion is provided, and a plurality of clamping portions 210 are provided to clamp and fix one or both ends of the wire harness 400, and a plurality of ultrasonic transducers 110 are provided.
[0054] Understandably, in some examples, a carrier portion is paired with several clamping portions 210, and the clamping portions 210 clamp and fix one end of the wire harness 400. In this case, multiple wire harnesses 400 are placed on the carrier portion in a wound manner and stacked in the vertical direction, with each clamping portion 210 correspondingly fixing the end of each wire harness 400. The number of ultrasonic transducers 110 is consistent with the number of clamping portions 210, and the ultrasonic transducers 110 can apply ultrasonic oscillation energy to the exposed shielding mesh 410 located near the clamping portions 210. The shielding mesh 410, after being broken up, can be grounded at one end.
[0055] In other examples, several clamping parts 210 clamp and fix the two ends of multiple wound wire harnesses 400, and several ultrasonic transducers 110 ultrasonically vibrate and break down the shielding mesh 410 at both ends of the wire harnesses 400. After the shielding mesh 410 on the wire harnesses 400 has been broken down, the wire harnesses 400 can be grounded at both ends through the shielding mesh 410.
[0056] In other embodiments, multiple carrier portions are provided, and these multiple carrier portions are spaced apart along a direction perpendicular to the conveying direction and the vertical direction. Several clamping portions 210 are provided to clamp and fix one or both ends of the wire harness 400. Simultaneously, the motion mechanism 120 is also configured to drive the ultrasonic transducer 110 to move along a direction perpendicular to the conveying direction and the vertical direction.
[0057] Understandably, assuming the conveying direction is left-right, multiple carriers are arranged at certain intervals along the front-back direction. Each carrier can hold a wound wire harness 400. Depending on whether the wire harness 400 is grounded at one or both ends, several clamping parts 210 clamp one or both ends of the wire harness 400 on each carrier. The motion mechanism 120 can be a two-axis or three-axis linear module, or it can be composed of multiple cylinders or electric cylinders. The motion mechanism 120 operates, driving the ultrasonic transducer 110 to move an appropriate distance along the front-back direction, causing the ultrasonic transducer 110 to sequentially apply ultrasonic oscillation energy to the shielding mesh 410 of the wire harness 400 on each carrier.
[0058] Of course, it is not excluded that in other embodiments, multiple ultrasonic transducers 110 are provided, and the multiple ultrasonic transducers 110 are spaced apart along the direction perpendicular to the conveying direction and the vertical direction. By using multiple ultrasonic transducers 110 to perform ultrasonic vibration to disperse the wire harness 400 shielding mesh 410 on the transport fixture 200, it is not necessary to drive the ultrasonic transducers 110 to move along the direction perpendicular to the vertical direction and the conveying direction through the motion mechanism 120.
[0059] In this embodiment, there are two carrier parts, and two clamping parts 210 are provided for each carrier part. The two clamping parts 210 can clamp and fix the two ends of the wire harness 400 respectively. The motion mechanism 120 can drive the ultrasonic transducer 110 to move in the up-down direction and the back-and-forth direction respectively, so as to gently disperse the shielding net 410 by ultrasonic vibration.
[0060] like Figures 1 to 3 As shown, the automatic wire harness assembly line according to the second aspect of the present invention includes a shielding mesh processing device based on ultrasonic vibration disintegration as described in the first aspect embodiment.
[0061] It is understood that the automatic wire harness assembly line also includes other processing equipment for processing wire harnesses 400, such as cutting equipment, terminal crimping equipment, and connector assembly equipment. However, this embodiment only makes structural improvements to the shielding mesh processing equipment based on ultrasonic vibration disintegration. Those skilled in the art should clearly understand the specific structure and working principle of other processing equipment, so other processing equipment will not be described in detail here.
[0062] The automatic assembly line for wire harnesses in this embodiment uses a shielding mesh processing device based on ultrasonic vibration to break down the shielding mesh 410 on the wire harness 400. This device can gently process the shielding mesh 410 on the wire harness 400 by using ultrasonic vibration to break down the shielding mesh 410, ensuring the structural integrity of the shielding mesh 410, maintaining good conductivity continuity, and providing excellent grounding performance.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
