Abstract
Description
Technical Field
[0001] The present invention relates to the technical field related to TEM horn antennas, and in particular to a copper foil efficient bending device based on 3D printing technology. Background Art
[0002] In the traditional TEM horn antenna design, the shape bending of the antenna radiation part usually requires traditional metal processing technology, such as mechanical bending, stamping, milling and other processes. Although these processes can achieve the predetermined bending shape, there are several obvious disadvantages. The first is the high cost and complex processing process. Traditional metal processing technology usually requires high-precision mechanical equipment, and the material loss during the processing is large, and it often requires multiple adjustments and repeated operations, resulting in high production costs. In addition, the manufacturing process is complex and involves multiple processes, from copper foil cutting, bending to surface treatment, etc., which require corresponding technical support and a large amount of manual operation. For application scenarios that require rapid iteration or low-volume production, the high cost and low efficiency of traditional processing methods often cannot meet the needs. The second is poor manufacturing flexibility. In the traditional manufacturing process, the accuracy of metal processing is limited by equipment and technology, and the shape of the processed copper foil is often fixed and difficult to adjust flexibly. When the design requirements or antenna specifications change, it is usually necessary to re-make the mold or adjust the production process, which greatly increases the R&D cycle and manufacturing costs. Therefore, the traditional method lacks sufficient flexibility and adaptability when facing complex or diversified design requirements. At the same time, there are also problems with process accuracy and consistency. Since traditional metal processing methods rely on manual operations, the errors in the process are often large, especially when large-scale production is required, and the differences between products may affect the performance of the final antenna. In the design of antennas with high precision requirements, even a small processing error may lead to inconsistencies in the propagation characteristics of electromagnetic waves, which in turn affects the working effect and performance stability of the antenna. In addition, the traditional TEM horn antenna has a long production cycle and slow response speed. Traditional antenna design often relies on multiple tests and modifications, and each modification requires remaking the mold or adjusting the production equipment. This not only prolongs the product design cycle, but also reduces the response speed to market changes. In the rapidly developing modern communication technology and scientific research fields, traditional manufacturing methods cannot meet the needs of rapid iteration and flexible production.
[0003] In summary, although the existing traditional metal processing technology has solved the shape bending problem in antenna design to a certain extent, its high cost, low efficiency, poor flexibility and unstable precision have seriously restricted its application in complex and high-precision antenna design. Therefore, a new, efficient, flexible and cost-controlled manufacturing method is urgently needed to overcome the limitations of existing technologies. Summary of the invention

DETAILED DESCRIPTION
[0034] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.
[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0036] Embodiment 1:
[0037] A copper foil efficient bending device based on 3D printing technology, such as Figure 1-Figure 13 As shown, it includes two symmetrically arranged slot frames 1 printed by a 3D printing device, a mounting slot 2 opened on one side of the slot frame 1 and used to install copper foil, a fixing member 3 used to connect and fix one end of the two slot frames 1, and an auxiliary mechanism. Specifically, one end of the slot frame 1 is bent outward from the main body and the bending curvature is a gradual curve with different exponents; the mounting slot 2 is a channel structure with openings at both ends and longitudinal curvature, the two ends of the mounting slot 2 are connected to the outside, and the curvature change of the mounting slot 2 is consistent with the arc edge of the slot frame 1; the auxiliary mechanism is used to facilitate the installation of the copper foil in the mounting slot 2;
[0038] The 3D printing device mentioned is a prior art structure. When printing the tank frame 1, it is operated based on the existing 3D printing technology. The materials used are selected according to the actual use situation and are not limited.
[0039] In the present invention, a slot frame 1 for copper foil installation can be quickly manufactured directly through 3D printing. The slot frame 1 structure with a preset installation slot 2 is manufactured through 3D printing. The geometric characteristics of the installation slot 2, such as depth, spacing, angle, etc., are used to control the deformation of the copper foil. Moreover, by using 3D printing technology, the bending angle tolerance of the installation slot 2 on the slot frame 1 can reach ±0.2°, and the surface smoothness Ra<1.6μm, which meets the radiation accuracy requirements of the 5G millimeter wave antenna.
[0040] A coaxial balun 19 connected to the end of the copper foil is provided on one side of the slot frame 1, and a loading medium 20 is provided between the two slot frames 1. The coaxial balun 19 is used for balanced conversion, and the loading medium 20 optimizes the impedance gradient. The cooperation of the two can improve the bandwidth and efficiency of the overall antenna. The two have a synergistic effect in electromagnetic performance regulation and signal transmission, and they also play different functional roles. When connecting with the coaxial balun 19, a soldering machine is used at the connection to make a reliable connection;
[0041] Specifically, two slot frames 1 printed by the 3D printing device are fixed symmetrically, and then the copper foil is inserted along the opening at one end of the installation slot 2. The copper foil undergoes plastic deformation along the bending structure of the installation slot 2 under the action of mechanical force. Since the thickness of the installation slot 2 is substantially the same as that of the copper foil, the installation slot 2 can also support the copper foil and reduce the vibration amplitude of the copper foil. During the installation process, an auxiliary mechanism can be used to guide the copper foil to slide and install in the installation slot 2, thereby avoiding the bending of the copper foil caused by manual installation.
[0042] The depth, spacing, angle and other designs of the installation slot 2 can accurately control the stress concentration point and achieve millimeter-level bending accuracy. Among them, by using this method to install the copper foil, the characteristic impedance of the coaxial cable of 50 ohms can be smoothly transitioned to the characteristic impedance of the free space of 377 ohms, so as to reduce the return loss of the antenna. Before mass production, the existing technology can be combined with finite element analysis to perform parametric modeling on the slot frame 1 structure to ensure the balance between the material ductility and the structural strength during the bending process, and then the information and drawings are transmitted to the 3D printing equipment, and finally the slot frame 1 with a certain degree of bending is printed out. Secondly, the TEM horn plate improved by different exponential gradient curves can be replaced by adjusting the slot frame 1, which reduces cost and time. Therefore, the TEM horn bracket based on 3D printing has the characteristics of fast processing and high production accuracy, and can be widely used in simple antenna production.
[0043] In order to solve the problem of fixing between the two slot frames 1; Figure 6As shown, a welding groove 30 and an inserting groove 31 are provided on the fixing part 3, one end of the slot frame 1 is movably engaged in the inserting groove 31, and a welding block 32 is connected to one end of the slot frame 1, and the welding block 32 is movably engaged with the welding groove 30. After the slot frame 1 is installed on the fixing part 3, the welding block 32 is connected to the welding groove 30 by welding.
[0044] In order to solve the problem of convenient and accurate installation of copper foil on the installation groove 2; Figure 7-Figure 11 As shown, the auxiliary mechanism includes a sliding rail 4 connected to the side of the slot frame 1 away from the mounting slot 2, a sliding member 5 slidably connected to the sliding rail 4, a connecting frame 6 connected to the sliding member 5, and a clamping assembly 7 connected to the connecting frame 6 and used to clamp the copper foil. When in use, the sliding member 5 is first slid onto the sliding rail 4, and then the clamping assembly 7 is connected to the connecting frame 6 and the copper foil is stably clamped. When the sliding member 5 is slid, the clamping assembly 7 will be driven to move through the connecting frame 6, thereby driving the copper foil to move in the mounting slot 2.
[0045] In order to solve the problem that the sliding member 5 can slide stably on the curved sliding track 4; Figure 7 As shown, the sliding member 5 includes two sliders 501 slidably connected to the sliding rail 4 and the two sliders 501 are connected to the connecting plate 502. The sliding rail 4 will be printed together with the slot frame 1 by the 3D printing device to keep the curvature of the two consistent. The two sliding blocks sliding on the sliding rail 4 will be more stable than a single sliding block sliding on the sliding rail 4. The two sliders 501 are rotatably connected to the connecting plate 502, so when passing through a curved route, they will bend adaptively. A paddle 503 for easy handholding is connected to the connecting plate 502.
[0046] In order to solve the problem of connecting the clamping assembly 7 for stably clamping the copper foil with the sliding member 5; Figure 8-Figure 11 As shown, first, the connecting frame 6 is connected to the connecting plate 502 on the sliding member 5, so the connecting frame 6 includes a disassembly block 601 connected to the connecting plate 502 and a driving rod 602 connected to the disassembly block 601 through a snap fitting, and a groove block 603 is connected to one end of the driving rod 602 away from the disassembly block 601, and a limiting groove 604 with a certain depth is opened at the end of the groove block 603.
[0047] Among them, the clamping assembly 7 includes a plug-in board 701 with one end movably connected to the limit groove 604, an adjusting member connected to the other end of the plug-in board 701, and two symmetrically arranged clamping plates 702 connected to the adjusting member. The adjusting member adjusts the distance between the two clamping plates 702 to stably clamp the copper foil. The side surface of the clamping plate 702 facing the copper foil has a certain curvature to avoid damage to the copper foil by the clamping plate 702 when the copper foil passes through a curved route.
[0048] In order to conveniently, stably and effectively stabilize the plug-in board 701 in the limiting groove 604, a fixing bolt 8 is provided on the limiting groove 604, and one end of the fixing bolt 8 passes through the top wall of the limiting groove 604 and extends into the limiting groove 604. When the plug-in board 701 is plugged into the limiting groove 604, the plug-in board 701 is supported and fixed by the fixing bolt 8.
[0049] The adjusting member includes a frame plate 703 fixedly connected to the plug-in board 701, two symmetrically arranged threaded plates 704 slidably connected in the frame plate 703, and a bidirectional threaded rod 705 rotatably connected in the frame plate 703, the two ends of the bidirectional threaded rod 705 are respectively threadedly connected to the two threaded plates 704, and the clamping plate 702 is connected to the threaded plates 704; a stop pad 706 is provided on the side of the frame plate 703 close to the clamping plate 702, and the stop pad 706 is in active contact with the edge of the copper foil. When the copper foil contacts the stop pad 706, the plug-in board 701 is stopped from being inserted into the limit groove 604, so as to avoid damage to the edge of the copper foil caused by the structure.
[0050] A sliding groove 9 is provided in the disassembling block 601, and the snap-fitting member includes a pin block 10 slidably connected in the sliding groove 9 and a spring 11 connecting the pin block 10 and the sliding groove 9. A snap-fitting groove 12 having a size corresponding to the pin block 10 is provided on the driving rod 602, and a pulling column 13 is fixedly connected to the pin block 10, and the pulling column 13 is slidably connected to the disassembling block 601;
[0051] A spring plate 14 and a second spring 15 connected to the spring plate 14 are provided on one side of the disassembly block 601. A push plate 16 is connected to one end of the second spring 15. When the driving rod 602 is clamped in the disassembly block 601, the push plate 16 contacts one end of the driving rod 602.
[0052] When the above-mentioned structure is in use, each structure is in a snap-connected state. Therefore, after the copper foil is installed in the installation slot 2, in order not to affect the transmission and radiation of the signal, the corresponding structure can be disassembled, and these structures can adapt to slot frames 1 with different bending angles. The same group of these structures can be used to install copper foils on multiple slot frames 1, which saves production costs and increases practicality.
[0053] Finally, an elastic sheet 17 is fixedly connected to the side surface of one side of the disassembly block 601, and an elastic sheet 2 1803 is connected to the position on the fixing member 3 corresponding to the elastic sheet 17. The elastic sheet 1 17 and the elastic sheet 2 1803 are respectively provided with protrusions and grooves, and the elastic sheet 1 17 and the elastic sheet 2 1803 are movably connected to facilitate stabilization of the sliding member 5 after the sliding is completed.
[0054] in, Fig.11 as well as Fig.12Through CST simulation, it is found that the standing wave ratio of the antenna structure is less than 2.5 in the 1-4GHz frequency band, and the maximum gain at each frequency is greater than 10dBi.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
