Description

Technical Field

[0001] This invention belongs to the field of precision wire welding technology, and specifically relates to a high-frequency induction welding device. Background Technology

[0002] High-speed data transmission cables are widely used in high-frequency communications, precision electronics, smart terminals, and high-speed interconnection devices. To meet global environmental control requirements and high-end cable performance standards, high-speed data transmission cables currently generally use PFAS-free environmentally friendly insulation materials to replace traditional fluorinated insulation materials. Such cables have stringent requirements for welding precision. On the one hand, the insulation layer has a narrow heat resistance window and is easily damaged by heat. On the other hand, the uniformity of core wire welding and impedance consistency directly determine the high-frequency transmission rate, signal anti-interference ability, and transmission stability of the cable. These are the core processing steps to ensure the performance of high-speed cables.

[0003] Currently, most precision wire welding processes employ contact heating welding techniques. The closest existing technology is a precision hot-press welding device for wires disclosed in Chinese invention patent (publication number: CN116206068A). This device uses a direct contact heating structure with a hot press head to achieve wire core welding through heat conduction. It can meet the basic welding and forming requirements of conventional electronic wires and is the current mainstream equipment solution for precision wire welding. Meanwhile, Chinese utility model patent (publication number: CN218123973U) discloses a resistance wire welding device that completes the welding operation by relying on electrode contact conduction and heating. It has a simple structure, is suitable for batch processing of conventional wires, and constitutes a general technical system for existing wire welding.

[0004] However, when the aforementioned traditional contact welding equipment and processes are applied to welding high-speed data transmission cables without PFAS insulation, the following inherent technical defects cannot be avoided:

[0005] 1. Contact welding relies on the direct contact of the heat source with the wire surface for heat transfer. The heat diffusion range is uncontrollable. Furthermore, the heat resistance of PFAS-free insulation materials is weaker than that of traditional fluorinated materials, making them prone to problems such as insulation layer burns, melting deformation, cracking, aging and damage.

[0006] 2. Contact heating has problems such as uneven heating and local overheating, poor consistency of wire core welding degree, and easy to produce welding defects such as incomplete welding, false welding, and uneven welding.

[0007] 3. Contact welding operations require mechanical pressure to press and weld, which can easily cause extrusion deformation and surface wear of the wire, damage the overall regularity of the wire, and deteriorate the electrical performance consistency of high-speed transmission wires;

[0008] Therefore, we need to propose a high-frequency induction welding device. Summary of the Invention

[0013] The lifting module is equipped with a wire pressing mechanism, and the fume purification module is installed on the wire pressing mechanism to adsorb the welding fumes.

[0014] Furthermore, the high-frequency induction generation module includes a second cylinder mounted on the equipment frame, and a magnet is provided at the telescopic end of the second cylinder.

[0015] Furthermore, the equipment frame is equipped with two sets of electric guide rails, and the two sets of electric guide rails are provided with two sets of mounting brackets for the installation of the lifting module. The vision alignment module and the carrier module are both located between the lifting module, and the lifting module is provided with a wire pressing mechanism for pressing the wire.

[0016] Furthermore, the lifting module includes a base frame fixedly connected to both ends of the two sets of mounting brackets.

[0017] Furthermore, the wire pressing mechanism includes a fixed plate fixedly connected to one side of the mounting base, a connecting plate provided on one side of the fixed plate, a guide tube fixedly connected to the end of the connecting plate, a pressing rod for positioning the wire inserted into the lower end of the guide tube, a guide rod penetrating the guide tube fixedly connected to the upper end of the pressing rod, and a spring located inside the guide tube sleeved on the outside of the guide rod.

[0018] Furthermore, the dust purification module includes a first clamp and two sets of second clamps. An air pipe is clamped inside the first clamp, and branch pipes connected to the air pipes are clamped inside the two sets of second clamps. An expansion mask is provided at the end of each set of branch pipes.

[0019] Furthermore, the first clamp is fixedly connected to one side of the fixed plate, the two sets of the second clamps are fixedly connected to both sides of the connecting plate, and the two sets of the branch pipes are respectively set on both sides of the lower end of the guide tube.

[0020] Furthermore, the vision alignment module includes two sets of corner plates fixedly connected to one side of the equipment frame, and an industrial camera is installed on each of the two sets of corner plates. The closed-loop temperature detection module is set on the corner plates.

[0021] Furthermore, the carrier module includes two sets of first cylinders disposed on the other side of the equipment frame, and the telescopic ends of the two sets of first cylinders are fixedly connected to a carrier frame. The upper surface of the carrier frame is provided with a cable groove for placing cables, and the lower surface of the telescopic carrier frame is symmetrically provided with two sets of clamping mechanisms for limiting the cable position.

[0022] Furthermore, the clamping mechanism includes a bidirectional lead screw disposed below the frame, with clamping plates for clamping the wire at both ends of the bidirectional lead screw, a telescopic rod disposed between the two sets of clamping plates, and an anti-slip strip disposed on one side of the clamping plates, and a rotary motor disposed at the end of the bidirectional lead screw.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention utilizes a non-contact, pressureless welding structure with a high-frequency induction generator module. The entire process involves no mechanical parts pressing or contacting the wire, effectively ensuring the integrity and regularity of the wire structure. Based on the principle of high-frequency electromagnetic induction non-contact welding, and leveraging the characteristics of metal magnetic heating and the non-magnetic, non-heating nature of PFAS-free non-metallic insulation layers, only the metal core of the wire is directionally heated and welded. This eliminates problems such as insulation layer burns, melting cracks, and thermal aging damage from the heat source perspective, fully preserving the insulation structure performance of the wire. It perfectly adapts to the welding processing requirements of PFAS-free environmentally friendly insulated wires, significantly reducing the product welding scrap rate.

[0025] 2. This invention, through an adjustable high-frequency induction generator module and magnetic field control structure, can adaptively adjust the induction frequency, magnetic field strength, and heating parameters to match different wire specifications, achieving precise and controllable core wire heating temperature and heating range, ensuring uniform and sufficient core wire welding, effectively eliminating defects such as incomplete soldering, false soldering, and uneven welding, guaranteeing high impedance consistency at the welding points, significantly reducing signal transmission attenuation, effectively improving the stability of high-speed data transmission and high-frequency anti-interference performance of the wire, and meeting the electrical performance requirements of high-end high-speed transmission wires;

[0026] 3. This invention utilizes a non-contact welding operation mode that eliminates mechanical contact and pressure pressing, thus avoiding problems such as wire deformation, surface wear, and structural damage caused by traditional welding processes. This effectively ensures the regularity of the wire's shape and the consistency of its structure, significantly improving the quality stability of mass production.

[0027] 4. This invention fills the technological gap in the existing industry by using a high-precision visual alignment mechanism, a closed-loop temperature control monitoring component, and an automated operation structure. It enables precise mass production of wire welding with accurate alignment, precise temperature control, and automated operation, effectively improving production efficiency, reducing manual intervention costs and product losses. The equipment has stronger adaptability and practicality and has good industrial promotion value.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1-7 As shown, this embodiment of the invention provides a high-frequency induction welding device, including a device frame 1 and a lifting module 4, a fume purification module 6, a vision alignment module 7, a carrier module 8, a high-frequency induction generation module 9, a magnetic field control module, and a closed-loop temperature detection module 10 mounted on the device frame 1.

[0040] The main control system is used to electrically connect with the lifting module 4, the smoke and dust purification module 6, the vision alignment module 7, the carrier module 8, the high-frequency induction generation module 9, the magnetic field control module, and the closed-loop temperature detection module 10.

[0041] The high-frequency induction generator module 9 is used to adaptively adjust the frequency of the high-frequency magnetic field, the magnetic field coverage range, and the heating time according to the wire diameter, core cross-sectional area, and insulation layer parameters of the wire to be processed.

[0042] The magnetic field control module is used to regulate and focus the output magnetic field, and to ensure that the high-frequency magnetic field accurately covers the area of ​​the core wire to be welded.

[0043] The lifting module 4 is equipped with a wire pressing mechanism 5, and the fume purification module 6 is installed on the wire pressing mechanism 5. The fume purification module 6 adsorbs the welding fumes.

[0044] Each functional mechanism is fixedly assembled inside the equipment frame 1 according to the wire processing flow. Each electrical control module is electrically connected to the main control system of the equipment. Through the unified timing scheduling of the main control system, fully automated precision welding operations such as automatic wire feeding, precise alignment, non-contact induction welding, temperature monitoring, and exhaust gas purification are realized.

[0045] In this embodiment, the high-frequency induction generation module 9 includes a second cylinder 91 mounted on the equipment frame 1, and a magnet 92 is mounted on the extension end of the second cylinder 91. Both ends of the magnet 92 are equipped with welding blades 94, and a coil 93 is mounted on the end of the magnet 92.

[0046] The coil 93, together with the magnet 92, can converge to form a directional high-frequency alternating magnetic field. The second cylinder 91 can quickly adjust the distance between the welding knife 94 and the wire braiding welding area. On the one hand, the magnetic field focusing distance can be flexibly adjusted according to different wire diameters and braiding layer thicknesses, accurately confining the magnetic field to the metal braiding layer and avoiding magnetic field diffusion that burns the heat-resistant, non-PFAS insulation layer. On the other hand, the integrated magnet 92 and welding knife 94 assembly has a compact structure, low magnetic field conduction loss, and higher heating power utilization, effectively ensuring that the core wire is fully and evenly welded, reducing defects such as incomplete welding and uneven welding.

[0047] Furthermore, two sets of electric guide rails 2 are installed on the equipment frame 1, and the two sets of electric guide rails 2 are provided with two sets of mounting brackets 3 for the installation of the lifting module 4. The vision alignment module 7 and the carrier module 8 are both located between the lifting module 4, and the lifting module 4 is provided with a wire pressing mechanism 5 for pressing the wire.

[0048] Two sets of electric guide rails 2, together with the mounting frame 3, enable the horizontal adjustment of the lifting module 4 over a wide range. The upper and lower lifting modules 4 are symmetrically arranged, with a reserved visual alignment and carrier processing station in the middle, forming an enclosed non-contact welding layout. The wire pressing mechanism 5 is integrated on the lifting module 4 and can be lifted and lowered synchronously to adapt to wires of different outer diameters. All functional modules of the whole machine are highly concentrated, and there is no spatial interference in the wire feeding, visual recognition, and induction welding processes, which shortens the wire station transfer stroke and has strong automation processing continuity. At the same time, the double-layer symmetrical layout makes the magnetic field of the upper and lower welding blades 94 symmetrical, and the temperature distribution of the welding point is uniform, further improving the impedance consistency of the welding point and meeting the low signal attenuation requirements of high-speed wires.

[0049] Secondly, the lifting module 4 includes a bottom frame 41 fixedly connected to both ends of the two sets of mounting brackets 3. The bottom frame 41 is provided with two sets of slide rails 42, and the two sets of slide rails 42 are provided with mounting seats 43. The bottom frame 41 is provided with an adjusting screw 44 for adjusting the position of the mounting seat 43. A servo motor 45 for driving the adjusting screw 44 is provided on one side of the bottom frame 41.

[0050] The servo motor 45 drives the adjusting screw 44, which, together with the slide rail 42 and the mounting base 43, forms a high-precision lifting and adjusting mechanism. The adjusting screw 44 has zero backlash and high repeatability, and can adjust the vertical height of the wire pressing mechanism 5 and the dust purification component at the micron level. For different specifications of non-PFAS wires in the range of 0.3-2.0mm, it precisely matches the pressing height of the pressure rod 54, flexibly limiting the wire without squeezing or deforming it, thus preventing wear on the wire surface and damage to the coaxial structure. At the same time, the slide rail 42 guides and ensures smooth lifting and lowering without deviation, so that the wire pressing and purification air intake are always aligned with the welding point, greatly improving the consistency of processing during mass production.

[0051] Specifically, the wire pressing mechanism 5 includes a fixing plate 51 fixedly connected to one side of the mounting base 43, a connecting plate 52 provided on one side of the fixing plate 51, a guide tube 53 fixedly connected to the end of the connecting plate 52, a pressing rod 54 for positioning the wire inserted into the lower end of the guide tube 53, a guide rod 55 passing through the guide tube 53 fixedly connected to the upper end of the pressing rod 54, and a spring 56 located inside the guide tube 53 is sleeved on the outside of the guide rod 55.

[0052] When the wire pressing mechanism 5 presses down on the wire through the pressure rod 54, it relies on the elastic buffer of the spring 56 to avoid rigid extrusion. It is perfectly compatible with the non-PFAS environmentally friendly insulation layer that is not pressure resistant, avoiding insulation flattening and cracking damage. The guide cylinder 53 and the guide rod 55 vertically limit the pressure rod 54. The pressure rod 54 always perpendicularly abuts against both sides of the wire. During the welding process, the braided welding area in the middle section of the wire will not move left and right or up and down. With the help of magnetic field directional heating, the position of the weld point is uniform and stable.

[0053] Furthermore, the dust purification module 6 includes a first clamp 61 and two sets of second clamps 64. The first clamp 61 is fitted with an air pipe 62, and the two sets of second clamps 64 are fitted with branch pipes 63 that are connected to the air pipe 62. The ends of the two sets of branch pipes 63 are provided with a diffuser 65.

[0054] By expanding the coverage of the smoke capture by the mask 65, the simultaneous air intake of the dual branches 63 can fully cover the welding area between the upper and lower welding blades 94. The trace organic waste gas and dust generated during the welding process can be adsorbed and filtered in real time without dead angles, preventing pollutants from adhering to the wire welding points and the non-PFAS insulation surface, and avoiding pollutants from affecting the high-frequency transmission anti-interference performance of the wire.

[0055] Specifically, the first clamp 61 is fixedly connected to one side of the fixed plate 51, the two sets of second clamps 64 are fixedly connected to both sides of the connecting plate 52, and the two sets of branch pipes 63 are respectively set on both sides of the lower end of the guide tube 53.

[0056] The air pipe 62 and branch pipe 63 are integrated and fixed on the fixing plate 51 and connecting plate 52 of the pressure mechanism 5 by the first clamp 61 and the second clamp 64. The mask 65 is arranged on both sides of the pressure rod 54 and close to the welding heating point. The smoking area rises and falls synchronously with the pressure mechanism 5, always maintaining the optimal adsorption distance with the welding point. There is no need to set up a separate displacement drive mechanism for the purification module, which simplifies the mechanical structure of the whole machine and reduces the equipment manufacturing cost and failure points.

[0057] It is worth noting that the vision alignment module 7 includes two sets of corner plates 71 fixedly connected to one side of the equipment frame 1, and an industrial camera 72 is installed on both sets of corner plates 71. The closed-loop temperature detection module 10 is set on the corner plate 71.

[0058] Two sets of corner plates 71 are equipped with industrial cameras 72 to achieve dual-view image acquisition of the wire from the top and bottom, which can completely identify all posture deviations such as vertical offset, tilt, and warping of the wire, and the alignment recognition accuracy is higher.

[0059] The closed-loop temperature detection module 10 is assembled synchronously with the common corner plate 71. The temperature sensor and the industrial camera 72 share the same workstation reference surface, which can synchronously acquire weld point images and real-time welding temperature data. The main control system can link up to complete alignment correction and dynamic adjustment of sensing power.

[0060] Specifically, the carrier module 8 includes two sets of first cylinders 83 set on the other side of the equipment frame 1, and the telescopic ends of the two sets of first cylinders 83 are fixedly connected to the carrier frame 81. The upper surface of the carrier frame 81 is provided with a cable groove 82 for placing cables, and the lower surface of the telescopic carrier frame 81 is symmetrically provided with two sets of clamping mechanisms 84 for limiting the cables.

[0061] Two sets of first cylinders 83 drive the carrier frame 81 to automatically feed and unload materials. The carrier frame 81 wire groove 82 supports the wire and the bottom integrates a clamping mechanism 84 to realize automated loading and unloading of wire, reduce manual clamping intervention, and improve batch production efficiency. The clamping mechanism 84 is arranged below the carrier frame 81 and will not block the field of view of the industrial camera 72 above or the high-frequency induction magnetic field path, and will not interfere with the visual alignment and induction heating process.

[0062] The wire groove 82 works in conjunction with the clamping mechanism 84 to initially limit the wire, pre-positioning the braided section of the wire to the welding reference, reducing the workload of subsequent vision module correction and shortening the cycle time of a single welding process.

[0063] In addition, the clamping mechanism 84 includes a bidirectional lead screw 842 disposed below the frame 81. Both ends of the bidirectional lead screw 842 are provided with clamping plates 843 for clamping the wire. A telescopic rod 845 is provided between the two sets of clamping plates 843. An anti-slip strip 844 is provided on one side of the clamping plate 843. A rotary motor 841 is provided at the end of the bidirectional lead screw 842.

[0064] The rotary motor 841 drives the bidirectional lead screw 842 to synchronously drive the two side clamping plates 843 to center and clamp. The telescopic rod 845 ensures that the clamping plates 843 open and close in parallel. The anti-slip strip 844 increases the friction with the non-PFAS insulation layer without scratching the insulation surface. The bidirectional lead screw 842 can automatically center and correct the wire, forming a double limit with the upper spring 56 and the pressure rod 54. The wire has no displacement or rotation throughout the welding process, completely eliminating welding defects caused by misalignment.

[0065] The 843 clamping plate synchronously centers and clamps to adapt to wires of different diameters, automatically centering them and significantly reducing impedance fluctuations at the solder joints. This ensures consistent electrical performance after high-speed wire welding. At the same time, the hidden bottom clamping structure does not block the magnetic field and does not affect the eddy current heating effect of the core wire.

[0066] During use, the first cylinder 83 drives the carrier frame 81 to feed, and the wire is placed in the wire groove 82. The bottom rotary motor 841 drives the bidirectional lead screw 842 to drive the two side clamps 843 to simultaneously center and clamp, completing the coarse positioning of the wire. After the carrier is transported to the welding station, the dual industrial cameras 72 simultaneously acquire images of the braided layer in the middle section of the wire, identify the wire offset and tilt deviation and feed back to the main control. With the carrier's fine adjustment, the welding point is accurately aligned. The servo motor 45 drives the lifting module 4 to rise and fall along the slide rail 42 through the adjusting lead screw 44, which drives the wire pressing mechanism 5 to move down. The pressing rod 54 relies on the spring 56 to flexibly press the outer insulation layer of the wire, limiting positioning without squeezing, and avoiding the PFAS-free insulation layer from being damaged by pressure. At the same time, the dust purification branch pipe 63 and the expanding mask 65, which rise and fall synchronously with the wire pressing mechanism 5, are closely attached to the welding area, forming a negative pressure adsorption environment in advance.

[0067] After alignment and wire pressing are completed, the second cylinder 91 pushes the magnet 92, coil 93, and welding knife 94 to move to both sides of the wire. The high-frequency induction generation module 9 adaptively outputs an alternating current with corresponding frequency, power, and duration according to the wire diameter, core cross-sectional area, and insulation parameters. With the assistance of the magnet 92, the coil 93 gathers and straightens to form a focused high-frequency magnetic field. The magnetic field only covers the metal braided layer of the wire. The braided wires are fused by the self-heating effect of the metal conductor eddy current. The non-metallic insulation layer without PFAS is non-magnetic and has no induced temperature rise, thus avoiding insulation burns and melting cracks from the source.

[0068] During the welding process, the closed-loop temperature detection module 10 installed on the corner plate 71 collects the temperature of the welding point in real time and sends the temperature signal back to the main control. The output power of the high-frequency induction module is dynamically adjusted to stabilize the welding temperature within the process range, preventing local overheating that could lead to incomplete welding or overburning. At the same time, the fume purification module 6 continuously adsorbs the organic waste gas and dust generated during welding under negative pressure, preventing pollutants from adhering to the wire and affecting the high-frequency transmission performance. After the heating process is completed, the induction module is powered off, the welding point cools naturally, the lifting module 4 and the carrier are reset in sequence, and the frame 81 automatically discharges the material, completing the fully automatic precision welding of a single wire in a cycle.

[0069] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
