Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically to an inductor welding fixture for radio frequency equipment. Background Technology

[0002] Coil inductors are core passive components in RF equipment such as radio frequency (RF) communication, microwave detection, and high-frequency signal transmission. They primarily perform key functions such as signal filtering, impedance matching, electromagnetic energy storage, and high-frequency resonance. Their processing precision and welding quality directly determine the signal stability, transmission efficiency, and overall lifespan of the RF equipment. Unlike conventional wire-wound inductors, coil inductors used in RF equipment often employ a precision hollow coil structure. The coil sidewalls are integrally formed or welded with metal mounting rings. These mounting rings enable the inductor's positioning and grounding on the RF cavity, circuit board, and equipment rack, forming a core structure that ensures the assembly precision and electromagnetic shielding performance of RF devices.

[0003] When positioning the welding fixture for the coil, the existing simple fixture can only achieve a rough placement and limit of the coil. The fixture has a single function, only having basic load-bearing function. During the welding process, problems such as coil deformation, eccentricity, and warping are very easy to occur during manual placement and welding heating. The roundness and concentricity accuracy of the coil directly affect its core electrical parameters such as inductance and high-frequency impedance. Once the deformation exceeds the standard, it will lead to increased radio frequency signal transmission loss and resonant frequency deviation, resulting in substandard device performance. At the same time, the simple placement and positioning method cannot limit the micro displacement of the coil during the welding process, which can easily cause defects such as welding misalignment, cold solder joints, and off-center solder joints. The product yield is low and cannot meet the actual use requirements.

[0004] Therefore, there is a need to provide an inductor soldering fixture for radio frequency devices, which aims to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] See Figures 1-6 A welding fixture for inductors used in radio frequency equipment includes a worktable 1. The worktable 1 has a first mating plate 3 and a second mating plate 5 for welding a coil 2. Both ends of the coil 2 are inserted into the first mating plate 3 and the second mating plate 5. One end of the first mating plate 3 is connected to a first mounting ring 4, and one end of the second mating plate 5 is connected to a second mounting ring 6. The fixture also includes:

[0032] The tooling limiting mechanism is installed on the outside of the coil 2, the first mounting ring 4, and the second mounting ring 6. It is used to limit the coil 2, the first mounting ring 4, and the second mounting ring 6. The tooling limiting mechanism includes a first limiting plate 13 and a second limiting plate 14 for side limiting. The second limiting plate 14 is movably installed on the workbench 1.

[0033] Furthermore, the tooling limiting mechanism also includes a receiving column 11 and a connecting block 12 for limiting the docking of the first docking plate 3 and the second docking plate 5. One end of the coil 2 is inserted into the receiving column 11 through the first docking plate 3. The receiving column 11 is fixedly installed on the workbench 1. The other end of the coil 2 is inserted into the second docking plate 5. The second docking plate 5 is fixedly installed on the connecting block 12 by bolts. The connecting block 12 is fixedly installed on the workbench 1.

[0034] Furthermore, the tooling limiting mechanism also includes a first pressure plate 9 for limiting the first mounting ring 4 and a second pressure plate 10 for limiting the second mounting ring 6. The worktable 1 is provided with a first snap-fit ​​groove 7 for fitting and placing the first mounting ring 4, and the worktable 1 is also provided with a second snap-fit ​​groove 8 for fitting and placing the second mounting ring 6. The first pressure plate 9 is fastened to the outside of the first mounting ring 4 by bolts, and the second pressure plate 10 is fastened to the outside of the second mounting ring 6 by bolts.

[0035] Furthermore, both sides of the first limiting plate 13 and the second limiting plate 14 are provided with several threaded holes. The second limiting plate 14 is provided with a waist-shaped mounting groove 15 for adjustment and installation at the docking point with the worktable 1. Both the first limiting plate 13 and the second limiting plate 14 are fixedly installed on the worktable 1 by bolts.

[0036] Furthermore, the bottom of the workbench 1 is provided with several support legs 27 for support.

[0037] Preferably, when positioning the coil 2, both ends of the coil 2 are inserted into the pipes on the first mating plate 3 and the second mating plate 5, respectively. Then, one end of the coil 2 is positioned on the receiving column 11 by the first mating plate 3, and the other end of the coil 2 is positioned on the mating block 12 by the second mating plate 5, thus effectively achieving the tooling positioning of both ends of the coil 2. The workbench 1 is correspondingly provided with a first snap-fit ​​groove 7 for placing the first mounting ring 4 and a second snap-fit ​​groove 8 for placing the second mounting ring 6. The first mounting ring 4 is pressed and limited by the first pressure plate 9, and the second mounting ring 6 is pressed and limited by the second pressure plate 10, thus effectively achieving the tooling positioning of the coil 2, the first mounting ring 4, and the second mating plate 5. According to the width of the coil 2, the first limiting plate 13 on one side is correspondingly limited, and the second limiting plate 14 on the other side can be adjusted and limited by the waist-shaped mounting groove 15 opened at the bottom and bolts, thus facilitating better inductor welding.

[0038] This rapid docking and installation method significantly improves welding alignment accuracy and assembly efficiency. During welding, the fixture ensures uniform contact between the side mounting ring and the coil sidewall, effectively controlling the assembly gap between them. This greatly enhances the weld strength and sealing performance, improving the overall structural stability of the device. Simultaneously, it simplifies the assembly process, reduces reliance on operator experience, and thus significantly improves welding production efficiency. Furthermore, the side can limit and correct the coil sidewall, effectively constraining displacement and deformation during welding, further reducing coil deformation. These two aspects complement each other, effectively improving product yield and production stability.

[0039] like Figures 1 to 8 As shown, this embodiment, based on the above embodiment, also includes a tooling adjustment mechanism, which is installed on the workbench 1 and is used to adjust the tooling height of the coil 2. The tooling adjustment mechanism includes a central support block 16 for adjusting the height of the coil 2. The central support block 16 has a support surface 17 adapted to connect the coil 2, and the support surface 17 is arc-shaped. The central support block 16 is movably mounted on the workbench 1.

[0040] Furthermore, the tooling adjustment mechanism also includes a lead screw 21 and a guide slide rod 19 for driving the central support block 16 to rise and fall. The central support block 16 is slidably connected to the worktable 1 and the lower edge seat 18 through the guide slide rod 19. The lower edge seat 18 is fixedly installed at the bottom of the worktable 1. One end of the guide slide rod 19 is provided with a limiting plate 20 for limiting the position, and the central support block 16 is threadedly connected to the lead screw 21.

[0041] Furthermore, the tooling adjustment mechanism also includes a rotary disk 26 for driving the lead screw 21 to rotate. One end of the lead screw 21 is fixedly mounted on the connecting shaft 22, and the connecting shaft 22 is rotatably mounted inside the lower edge seat 18. A worm gear 23 is fixedly connected to the connecting shaft 22, and a worm 24 is meshed on the worm gear 23. The worm 24 is rotatably mounted on the lower edge seat 18 through a rotating rod 25, and one end of the rotating rod 25 is fixedly connected to the rotary disk 26.

[0042] Preferably, in this embodiment, in order to better clamp the coil 2 and improve the docking efficiency, the height of the central support block 16 can be adjusted to achieve good clamping of the coil 2. The specific operation method is as follows: by adjusting the rotating disk 26 to drive the worm 24 on the rotating rod 25 to rotate, the worm 24 and the worm wheel 23 are meshed and connected, which drives the lead screw 21 on the connecting shaft 22 to rotate. Then, under the threaded connection between the central support block 16 and the lead screw 21 and the limiting and guiding action of the guide slide 19, the central support block 16 can be driven to perform lifting and lowering adjustment, thereby facilitating better subsequent docking and installation and inductor welding.

[0043] With the adjustable height center support block, the height can be adjusted to match the overall size of the inductor coil to be processed, thus effectively matching the coil's structural dimensions. This height-adaptive adjustment method can significantly improve tooling utilization, meet the production needs of RF inductors, substantially increase the yield rate of RF inductor soldering, reduce rework and repair costs, improve product quality, and meet the needs of industrial mass production.

[0044] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
