Description

Technical Field

[0001] This invention relates to the field of ultra-fine coaxial cable welding technology, specifically an ultra-fine coaxial cable positioning welding device. Background Technology

[0002] Ultra-fine coaxial cable is a miniaturized coaxial cable structure. This special cable employs a multi-layered composite structure design, comprising four key parts from the inside out: a center conductor, an insulating dielectric layer, an outer shielding layer, and an outermost protective sheath. The center conductor transmits electrical signals, the insulating layer ensures electrical isolation between conductors, the shielding layer provides electromagnetic interference protection, and the outermost sheath protects the internal structure from physical damage and environmental corrosion.

[0003] When soldering ultra-fine coaxial cables, the soldering end of the ultra-fine coaxial cable is positioned in the slot on the top of the ribbon cable board through a slot arrangement. The slot prevents the ultra-fine coaxial cables from overlapping. The miniature solder pads that need to be soldered and fixed to the ultra-fine coaxial cable are placed in the groove on the top of the PCB positioning board. After the arrangement, the fixing seat on the pressure plate is pulled to make the fixing seat lock into the slot, and the buckle at the bottom of the fixing seat locks into the slot. The pressure plate presses on the top of the ribbon cable board and the ultra-fine coaxial cable, further positioning the ultra-fine coaxial cable in the slot. This ensures that the ultra-fine coaxial cable is fixed and does not loosen during the wiring process, preventing misalignment during soldering. However, the existing technology not only cannot be adapted to different coaxial cables, but also cannot protect the coaxial cable during soldering. Therefore, it needs to be improved.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example 1, please refer to Figures 1-5 A positioning and welding device for ultra-fine coaxial cables includes a fixed base platform 1, with cross support rods 2 at the bottom of the fixed base platform 1. Two symmetrically arranged feed alignment mechanisms 3 are provided on the fixed base platform 1, and multiple sealing mechanisms 4 are provided on the feed alignment mechanisms 3. A welding box mechanism 5 is provided on the fixed base platform 1, and a rotating sealing plate mechanism 6 is provided on the welding box mechanism 5. A welding mechanism 7 is provided inside the welding box mechanism 5. A placement plate 8 is fixedly connected to the welding box mechanism 5 below the welding mechanism 7. A positioning support mechanism 9 is provided on the placement plate 8, and two symmetrically arranged alignment slot plate mechanisms 10 are provided on the placement plate 8. The feed alignment mechanisms 3 drive the multiple sealing mechanisms 4 to feed, the rotating sealing plate mechanism 6 controls the closed state of the welding box mechanism 5, and the positioning support mechanism 9 positions and fixes the substrate.

[0025] The multiple sealing mechanism 4 includes a lifting rod 401 on the feed plate 304, a positioning cylinder 402 on the lifting rod 401, and a plurality of first electrically controlled inflation and deflation sealing rings 403 inside the positioning cylinder 402.

[0026] Specifically, when the coaxial cable passes through the first electrically controlled gas filling and discharging sealing ring 403, opening the first electrically controlled gas filling and discharging sealing ring 403 can fix the coaxial cable and prevent subsequent gas leakage.

[0027] The welding box mechanism 5 includes two mounting plates 501 fixed to the fixed base 1. The mounting plates 501 are fixedly connected to the welding box 502. The welding box 502 has an operation slot 503 and is a cylindrical structure. A placement slot 504 is provided on the side of the welding box 502. A second electrically controlled inflation / deflation sealing ring 505 is located at the placement slot 504 on the welding box 502. An inlet / exhaust port 506 and a pressure gauge 507 are also provided on the side of the welding box 502. The rotating sealing plate mechanism 6 includes a rotating ring 601 rotatably connected to the welding box 502. A first gear 602 is fixedly connected to the outer side of the rotating ring 601. An arc-shaped sealing plate 603 is fixedly connected to the rotating ring 601. A motor base 604 is fixedly connected to the fixed base 1. A second motor 605 is fixedly connected to the motor base 604. The output shaft of the second motor 605 is fixedly connected to a second gear 606. The second gear 606 meshes with the first gear 602.

[0028] Specifically, when the second motor 605 is turned on, the output shaft of the second motor 605 rotates, which drives the second gear 606 to rotate. The rotation of the second gear 606 drives the first gear 602 to rotate, which in turn drives the rotating ring 601 to rotate, thereby driving the arc-shaped sealing plate 603 to rotate. This is used to adjust the overlapping area of ​​the arc-shaped sealing plate 603 and the placement groove 504, thus adjusting the closed state of the welding box 502.

[0029] In addition, after the welding box 502 is sealed, protective gas can be introduced into the welding box 502 through the inlet and outlet ports 506. The gas pressure inside the welding box 502 can be monitored in real time by the barometer 507. The presence of protective gas can protect the welding process and ensure efficient welding.

[0030] The welding mechanism 7 includes a first linear motor 701 fixed inside the welding box 502, and the end of the first linear motor 701 is fixedly connected to the welding head 702. The positioning support mechanism 9 includes a displacement shaft 901 rotatably connected to the placement plate 8. The displacement shaft 901 has two symmetrically arranged threaded grooves 902. The placement plate 8 has a third motor 903. The output shaft of the third motor 903 is coaxially and fixedly connected to the displacement shaft 901. The displacement shaft 901 is threadedly connected to two symmetrically arranged support side plates 904. The support side plates 904 and the placement plate 8 are slidably connected. The inner side of the support side plate 904 is fixedly connected to a wedge-shaped groove clamping plate 905. The support side plate 904 is fixedly connected to a second linear motor 906. The end of the second linear motor 906 is fixedly connected to an adjusting plate 907. The adjusting plate 907 is fixedly connected to a support base plate 908. The support base plate 908 passes through the support side plate 904. The support base plate 908 and the support side plate 904 are slidably connected. The inner side of the support side plate 904 is fixedly connected to two laser cutters 909. The two laser cutters 909 are symmetrically arranged on the support side plate 904. The alignment slot plate mechanism 10 includes a mounting shaft 1001 fixed on the placement plate 8. A mounting sleeve 1002 is provided on the outer side of the mounting shaft 1001. The mounting sleeve 1002 and the mounting shaft 1001 are slidably connected. The mounting sleeve 1002 is threadedly connected to a locking bolt 1003. The mounting sleeve 1002 is fixedly connected to a docking plate 1004. The docking plate 1004 is provided with a plurality of alignment slots 1005 and a top baffle 1006.

[0031] Specifically, when the coaxial cable is placed on the placement plate 8, the third motor 903 is turned on. The output shaft of the third motor 903 rotates, which drives the displacement shaft 901 to rotate, and then drives the threaded groove 902 to rotate. This causes the two support side plates 904 to move inward, and then drives the wedge-shaped groove clamping plate 905 to move inward, so as to achieve clamping and fixing of the substrate. In addition, turning on the second linear motor 906 can drive the adjustment plate 907 to feed, and then drive the support base plate 908 to feed. The support base plate 908 can support the bottom of the substrate.

[0032] Additionally, when the coaxial cable is placed on the alignment slot 1005, as the coaxial cable moves forward, the longer coaxial cable will extend out of the mating plate 1004 first. At this time, turning on the laser cutter 909 can cut the uneven coaxial cables to ensure the subsequent welding quality.

[0033] Example 2, see below. Figures 1-2In this embodiment of the invention, the feed alignment mechanism 3 includes a feed groove 301 formed on a fixed base 1, a feed threaded rod 302 rotatably connected to the fixed base 1 within the feed groove 301, a first motor 303 provided on the fixed base 1, the output shaft of the first motor 303 and the feed threaded rod 302 being coaxially and fixedly connected, the feed threaded rod 302 being threadedly connected to a feed plate 304, and the feed plate 304 and the fixed base 1 being slidably connected.

[0034] Specifically, turning on the first motor 303 can drive the feed thread rod 302 to rotate, thereby driving the feed plate 304 to move along the feed groove 301, so as to drive the coaxial feed displacement.

[0035] In the implementation of this invention, the coaxial cable to be welded is first passed through the multi-sealing mechanism 4, which clamps and fixes the coaxial cable. Then, the feed alignment mechanism 3 is activated, which drives the multi-sealing mechanism 4 to feed, thereby driving the coaxial cable to feed, so that the multi-sealing mechanism 4 connects with the welding box mechanism 5. At the same time, the coaxial cable to be aligned and welded is passed through the alignment slot plate mechanism 10. If the coaxial cable needs to be installed on the PCB board, the positioning support mechanism 9 clamps and fixes the PCB board. Then, the rotating sealing plate mechanism 6 is activated, which closes the welding box mechanism 5. Then, protective gas is introduced into the welding box mechanism 5 to protect the welding process. At this time, the welding mechanism 7 is activated to perform welding. At the same time, the positioning support mechanism 9 can laser cut longer coaxial cables to ensure that the welded coaxial cables are all of the same length, ensuring the uniformity and stability of subsequent products.

[0036] This invention can fix wires of different diameters by setting up multiple sealing mechanisms 4, and at the same time achieve sealing. The feed alignment mechanism 3 can drive linear feed alignment. The rotating sealing plate mechanism 6 can adjust the closed state of the welding box mechanism 5, and at the same time, it can introduce protective gas into the closed space for protective welding. The positioning support mechanism 9 can position and fix substrates of different sizes. The alignment slot plate mechanism 10 can select appropriate support plates according to the different adaptability of coaxial wires, thereby increasing the welding performance of ultra-fine coaxial wires.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
