Description

Technical Field

[0001] The utility model relates to the technical field of antenna testing, in particular to an antenna testing alignment device. Background Art

[0002] In antenna test scenarios such as planar near- and far-field test systems and spherical near-field multi-probe calibration, the spatial alignment between the receiving antenna and the transmitting antenna has a significant impact on the system test efficiency. Therefore, the transmitting antenna and the receiving antenna must be aligned before the antenna test. If the antenna is aligned manually, the alignment accuracy of the antenna is reduced due to the long distance between the antennas and the line of sight error. Frequent tests are required to determine whether the antenna is aligned. The alignment is difficult and the alignment accuracy is low, which greatly reduces the antenna test efficiency.

[0003] At present, operators use visible lasers to complete antenna alignment operations. For example, a Chinese invention patent application with application publication number CN112858798A provides an antenna testing system, an antenna support device, and an antenna testing method. A first support frame and a second support frame are used to respectively connect a standard antenna sample and an antenna sample to be tested, and then an alignment device is used to align through a light-transmitting gap opened on the first support frame with a first alignment mark pre-set on the second support frame, thereby realizing the pre-test alignment of 2G antennas, 3G antennas, 4G antennas, and 5G millimeter-wave phased array antennas.

[0004] However, existing devices using lasers for alignment require an alignment operation before each antenna test, which is cumbersome and inefficient. On the other hand, when aligning antennas of different specifications, support frames of corresponding specifications need to be provided to connect to the antennas, thereby increasing the test cost and failing to meet actual test needs.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0034] In the description of the embodiments of the present utility model, it should be noted that if the terms "left", "right", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0035] Specifically, the utility model provides an antenna test alignment device, including a position adjustment unit 10 and an antenna center alignment unit; wherein, the position adjustment unit 10 is used to connect a receiving antenna, and the receiving antenna needs to be aligned with the transmitting antenna 80 according to the specifications of the transmitting antenna 80, so as to facilitate subsequent antenna testing; therefore, the position adjustment unit 10 is used to drive the receiving antenna to move or rotate, thereby making the adjustment of the receiving antenna more convenient and quick.

[0036] The antenna center alignment unit is connected to the position adjustment unit 10, and the position adjustment unit 10 is used to drive the antenna center alignment unit to move. The visible laser emitted by the antenna center alignment unit is aligned with the center of the transmitting antenna 80. The center position of the receiving antenna aligned with the transmitting antenna 80 can be determined according to the moving distance or rotation angle of the position adjustment unit 10, and the alignment position of the transmitting antenna 80 is obtained, thereby realizing the alignment of the antenna. The operation is simple and fast, improves the alignment efficiency of the antenna, shortens the alignment time of the antenna, ensures the alignment of the antenna, further improves the test efficiency of the antenna, and meets the actual test needs.

[0037] Further explanation, in order to further facilitate the operation, the receiving antenna can be connected to the position adjustment unit 10, and the antenna center alignment unit can be connected to the position adjustment unit 10 at the same time, so that the antenna center alignment unit is located at the center position of the receiving antenna, thereby performing the antenna alignment operation, further shortening the antenna alignment time and improving the antenna testing efficiency.

[0038] After completing the alignment operation of the transmitting antenna 80 once, the alignment position determined by the position adjustment unit 10 can be used to align different receiving antennas with the transmitting antenna 80 of the same specification, further improving the antenna testing efficiency. At this time, the position of the transmitting antenna 80 remains unchanged.

[0039] Example 1

[0040] refer to Figure 1 This embodiment provides an antenna test alignment device, wherein the position adjustment unit 10 includes a horizontal track 13, a horizontal moving mechanism 11 and a vertical moving mechanism 12 connected in sequence; the antenna center alignment unit is described by taking the laser body 40 as an example.

[0041] Among them, the horizontal track 13 is laid horizontally along the longitudinal direction, and the horizontal moving mechanism 11 is slidably connected to the horizontal track 13, so that the horizontal moving mechanism 11 can move stably along the horizontal track 13, and at the same time the vertical moving mechanism 12 is connected to the horizontal moving mechanism 11, and the horizontal moving mechanism 11 can drive the vertical moving mechanism 12 to move horizontally; the antenna center alignment unit is connected to the vertical moving mechanism 12, and the vertical moving mechanism 12 can drive the antenna center alignment unit to move back and forth in the vertical direction; therefore, during use, the antenna center alignment unit can change the vertical height and the distance in the longitudinal direction under the drive of the horizontal moving mechanism 11 and the vertical moving mechanism 12.

[0042] refer to Figure 2 The vertical moving mechanism 12 includes a vertical connecting member, a vertical driving member and a vertical supporting member; the vertical supporting member is vertically arranged, the bottom of the vertical supporting member is connected to the top of the horizontal moving mechanism 11, the vertical connecting member is sleeved on the outside of the vertical supporting member, a vertical rack is arranged on the vertical supporting member, the fixed end of the vertical driving member is connected to the vertical connecting member, the output end of the vertical driving member cooperates with the vertical rack through a gear, the vertical driving member drives the vertical connecting member to move up and down by driving the gear forward and reverse; the laser body 40 is connected to the vertical connecting member.

[0043] The transmitting antenna 80 is arranged on the opposite side of the horizontal track 13. The distance between the transmitting antenna 80 and the horizontal track 13 in the lateral direction is adjusted according to needs. The transmitting antenna 80 is arranged vertically, and the transmitting surface of the transmitting antenna 80 faces the position adjustment unit 10 in the lateral direction.

[0044] During the alignment process, the laser body 40 is first connected to the vertical moving mechanism 12, while ensuring that the laser emitted by the laser body 40 is in a horizontal state. Subsequently, the vertical height and longitudinal distance of the antenna center alignment unit are adjusted by the horizontal moving mechanism 11 and the vertical moving mechanism 12 until the laser emitted by the antenna center alignment unit is aligned with the center of the transmitting antenna 80. At this time, the distance data of the horizontal moving mechanism 11 and the height data of the vertical moving mechanism 12 are recorded to obtain the position information of the antenna center alignment unit. According to the position information of the antenna center alignment unit, the position of the receiving antenna aligned with the transmitting antenna 80 can be obtained.

[0045] Then, after removing the antenna center alignment unit, connect the center position of the receiving antenna to the vertical moving mechanism 12. According to the corresponding alignment position of the transmitting antenna 80, adjust the horizontal moving mechanism 11 and the vertical moving mechanism 12 to move the receiving antenna to the corresponding position. At this time, the receiving antenna is aligned with the transmitting antenna 80, thereby completing the antenna alignment operation.

[0046] In order to further improve the alignment efficiency, the center position of the receiving antenna can be connected to the vertical moving mechanism 12, and then the antenna center alignment unit can be connected to the center position of the receiving antenna, so that when the laser is used to align with the transmitting antenna 80, the transmitting antenna 80 and the receiving antenna are aligned synchronously.

[0047] Example 2

[0048] refer to Figure 3 In the antenna test alignment device provided in this embodiment, the position adjustment unit 10 includes a support frame 14 and a rotating disk 15; similarly, the antenna center alignment unit is described by taking the laser body 40 as an example.

[0049] What is different from Example 1 is that there are multiple transmitting antennas 80, and the multiple transmitting antennas 80 are all connected to a transmitting bracket. The transmitting bracket is an arc-shaped structure. The multiple transmitting antennas 80 are arranged at intervals along the arc of the transmitting bracket, and the transmitting end of each transmitting antenna 80 is facing the center of the transmitting bracket; the number of transmitting antennas 80 and the angle between two adjacent transmitting antennas 80 vary according to actual needs.

[0050] Among them, the number of receiving antennas is one, and the receiving antenna is connected to the rotating disk 15 along the radial direction of the rotating disk 15. The center of the rotating disk 15 is located at the center of the transmitting bracket. The rotating disk 15 is supported by the support frame 14, and the rotating disk 15 is rotatably connected to the support frame 14. During the antenna test process, the rotating disk 15 is driven to rotate so that the receiving antenna is tested with each transmitting antenna 80 in turn.

[0051] Therefore, when aligning the antenna, the antenna center alignment unit is connected to the rotating disk 15, and the antenna center alignment unit is set along the radial direction of the rotating disk 15. The rotating disk 15 then drives the antenna center alignment unit to rotate until the laser emitted by the antenna center alignment unit is aligned with the center of the first transmitting antenna 80. At this time, the alignment position of the first transmitting antenna 80, that is, the position information of the antenna center alignment unit, is recorded.

[0052] Among them, the alignment position is the rotation angle of the antenna center alignment unit; this cycle is repeated to align each transmitting antenna 80 in turn, and the alignment position of each transmitting antenna 80 is recorded. Therefore, after the receiving antenna is connected to the rotating disk 15, the receiving antenna can be aligned with each transmitting antenna 80 according to the recorded alignment position, thereby ensuring that subsequent antenna tests are completed efficiently and reliably.

[0053] Similarly, in order to improve the alignment efficiency, the antenna center alignment unit can be connected to the center position of the receiving antenna, and the receiving antenna is then connected to the rotating disk 15. After the alignment is completed, the antenna center alignment unit can be removed to perform antenna testing.

[0054] Example 3

[0055] refer to Figure 4~Figure 6 In this embodiment, an antenna test alignment device is provided, and the antenna center alignment unit includes a mounting base 20, a laser support seat 30, a laser body 40 and a power supply 50; wherein, the top of the laser support seat 30 is connected to the laser body 40, and the bottom of the laser support seat 30 is connected to the position adjustment unit 10 through the mounting base 20; the power supply 50 is installed on the laser support seat 30, and the power supply 50 is electrically connected to the laser body 40 to provide electrical energy for the laser body 40.

[0056] The laser body 40 is coaxially connected to the laser support seat 30 , and the laser support seat 30 is connected to the vertical moving mechanism 12 or the rotating disk 15 through the mounting base 20 .

[0057] To further illustrate, the laser body 40 and the mounting base 20 are preferably coaxially arranged with the laser support base 30, so that when the mounting base 20 is connected to the position adjustment unit 10, the visible laser emitted by the laser body 40 is coaxial with the center of the receiving antenna, thereby ensuring the reliability of the alignment position of the receiving antenna.

[0058] refer to Figure 5 , Figure 6 and Figure 7 It is further preferred that the laser support seat 30 and the position adjustment unit 10 are both detachably connected to the mounting base plate 20. At this time, multiple first connecting holes 21 and multiple first mounting holes 22 are selected to be opened on the mounting base plate 20. The multiple first connecting holes 21 are arranged around the axis circumference of the mounting base plate 20, and the multiple first mounting holes 22 are also arranged around the axis circumference of the mounting base plate 20. The first mounting holes 22 are located in the outer circle of the first connecting holes 21.

[0059] Taking the five first connection holes 21 as an example, the five first connection holes 21 are arranged at equal intervals around the axis of the mounting base 20, and correspondingly, five second connection holes 31 are opened at the bottom of the laser support seat 30, and the five second connection holes 31 are arranged at equal intervals around the axis of the laser support seat 30. At this time, the first connection hole 21 and the second connection hole 31 can be aligned and fastened by connecting bolts, thereby completing the coaxial setting of the laser support seat 30 and the mounting base 20.

[0060] Taking the four first mounting holes 22 as an example, the four first mounting holes 22 are arranged at equal intervals around the axis of the mounting base plate 20, and second mounting holes matching the first mounting holes 22 are correspondingly opened on the vertical moving mechanism 12 or the rotating disk 15. During installation, they can be connected by mounting bolts, which is convenient for disassembly and assembly, and can ensure the reliability of the installation position and reduce installation errors.

[0061] To further explain, the mounting base plate 20 can also be detachably connected to the receiving antenna.

[0062] refer to Figure 3 and Figure 4 When the antenna center alignment unit is connected to the vertical moving mechanism 12, the emitted laser needs to be kept horizontal, that is, the laser body 40 needs to be set horizontally. Therefore, it is preferred to set a bubble level 60 on the laser support seat 30. During the installation process, the bubble level 60 can be used to adjust the laser support seat 30 horizontally to ensure the horizontal installation of the laser body 40 and improve the alignment accuracy and reliability.

[0063] In order to improve the protection of the laser body 40, the laser body 40 is preferably arranged inside the laser support seat 30, that is, the laser support seat 30 is sleeved on the outside of the laser body 40, and the laser body 40 is connected to the inside of the laser support seat 30 to ensure its stable installation; at the same time, a protective end cover 32 is preferably arranged at the top of the laser support seat 30, and a laser irradiation hole is opened at the center position of the protective end cover 32. The inner diameter of the laser irradiation hole is larger than the outer diameter of the visible laser, and the laser irradiation hole is coaxially arranged with the laser body 40.

[0064] Example 4

[0065] refer to Figure 6 In order to ensure the pointing accuracy of the laser body 40 and improve the alignment accuracy of the antenna, an antenna test alignment device provided in this embodiment is preferably configured such that the laser body 40 is movably connected to the laser support seat 30 .

[0066] Specifically, a rotating connecting disk is provided on the laser support seat 30, and the rotating connecting disk can be selectively set between the laser support seat 30 and the mounting base plate 20, or the rotating connecting disk is set at the bottom of the mounting base plate 20, and the mounting base plate 20 is connected to the position adjustment unit 10 through the rotating connecting disk; the rotating connecting disk drives the laser support seat 30 to rotate around the axis of the laser support seat 30.

[0067] A laser connecting sleeve 70 is sleeved on the outer side of the laser body 40, and the laser body 40 and the laser connecting sleeve 70 are coaxially arranged, and the laser body 40 and the laser connecting sleeve 70 can be optionally threadedly connected; one end of the laser connecting sleeve 70 is movably connected to the laser support seat 30 through a joint bearing 72, and a plurality of adjusting bolts 71 are arranged on the circumference of the other end of the laser connecting sleeve 70, and the adjusting bolts 71 are threadedly connected to the laser support seat 30 along the radial direction of the laser support seat 30, so that by rotating the adjusting bolts 71, the adjusting bolts 71 can be controlled to approach or move away from the axis of the laser support seat 30, and the plurality of adjusting bolts 71 are arranged at intervals around the axis of the laser support seat 30, and preferably, the plurality of adjusting bolts 71 are arranged at equal intervals around the axis of the laser support seat 30. Taking four adjusting bolts 71 as an example, one end of the adjusting bolt 71 extending to the inside of the laser support seat 30 is the contact end of the adjusting bolt 71, and the contact end of the adjusting bolt 71 contacts the outer surface of the laser connecting sleeve 70.

[0068] In order to ensure the accuracy of antenna alignment, before actual use, the rotating connection disk is connected to the position adjustment unit 10, and the rotating connection disk is started after the laser body 40 is started. If there is an angle between the axis of the laser body 40 and the axis of the rotating connection disk, the laser emitted by the laser body 40 will form a circular track on the irradiation surface during the rotation of the rotating connection disk. According to the radius r of the circular track and the distance L between the emission end of the laser body 40 and the irradiation surface, it can be Get the pointing accuracy of the laser body 40 α .

[0069] The deflection angle of the laser body 40 is fine-tuned by rotating the adjusting bolt 71 , and then the pointing accuracy of the laser body 40 is continuously measured until the pointing accuracy of the laser body 40 meets the alignment requirement.

[0070] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
