Description

Technical Field

[0001] The present invention belongs to the technical field of double-ridged horn receiving antenna installation, and in particular relates to a double-ridged horn receiving antenna installation device and an installation method thereof. Background Art

[0002] The EMC market refers to the market for electromagnetic compatibility (EMC) testing and certification. There are three main types of receiving antennas that are widely used in the EMC market. Among them, the beam width of Schwarzbeck's BBHA9120D type cannot fully meet the test requirements. During testing, it is necessary to change the test angle multiple times to achieve irradiation of the EUT sample, which greatly affects the sample detection efficiency. ETS's 3117 type is a double-ridged open-waveguide horn antenna. The beam width meets the standard requirements, but the voltage standing wave ratio from 1GHz to 2GHz is relatively poor (around 3.5), and it can easily affect the service life of the measurement receiver. R&S's HF907 is a high-gain transceiver antenna with a built-in reflector. The relevant indicators meet the test scenarios, but this antenna needs to be terminated with a preamplifier and is expensive.

[0003] A double-ridged horn antenna, serving as a receiving antenna, was rationally designed and developed to meet project requirements. The specific plan is as follows: 1) Theoretical analysis of the operating principle of the double-ridged horn antenna was conducted; 2) Advanced electromagnetic simulation tools (HFSS, CST, etc.) were utilized in conjunction with experimental testing to repeatedly optimize the shape, size, and internal structure of the horn and waveguide ridges, finding the optimal geometric configuration to suppress mainlobe splitting, achieve efficient broadband radiation, and ensure good performance across multiple frequency bands; 3) Finally, a comprehensive process for designing a suitably sized horn antenna, from design to processing and assembly, was developed.

[0004] However, traditional dual-ridge assembly methods often suffer from issues such as difficulty maintaining mounting accuracy and looseness, which directly impact the performance stability and service life of horn receiving antennas. Therefore, a dual-ridge horn receiving antenna mounting device and method are needed to improve dual-ridge mounting accuracy and ensure the performance stability and service life of horn receiving antennas. Summary of the Invention

[0028] The rotating assembly includes a driving assembly and a supporting assembly. The driving assembly is used to provide rotational power, and the supporting assembly is used to play a supporting role. The driving assembly includes a motor fixed inside the chassis 1 (not shown in the figure), a fixed disk 7 fixed on the chassis 1, and a rotating disk 22 is connected to the middle of the fixed disk 7 through a bearing.

The tops of the four groups of support rods 5 are fixedly connected to the carrying plate 2. The starting motor drives the rotating plate 22 to rotate, and drives the carrying plate 2 to rotate through the connecting column 6. When the carrying plate 2 rotates, the support rods 5 can support the carrying plate 2 and disperse the weight of the carrying plate 2.

[0030] Four groups of square grooves 19 are formed around the carrier plate 2 , and each group of square grooves 19 corresponds to a group of mounting components.

[0031] The mounting assembly includes a lifting assembly and a clamping assembly. The lifting assembly is used to control the lifting and lowering of the clamping assembly. The clamping assembly is used to clamp the upper ridge 15 and the lower ridge 21. The lifting assembly includes a mounting seat 9 fixed on the carrying plate 2 and four groups of slide bars 10 slidably connected to the mounting seat 9 and passing through the groove 19 above the carrying plate 2. Each square groove 19 is provided with a mounting seat 9. The upper ends of the four groups of slide bars 10 pass through the square groove 19 and the mounting seat 9 and can slide up and down along the mounting seat 9. A first cylinder 3 is fixed on the top of the mounting seat 9. The first cylinder 3 is connected to the lifting plate 11 located at the lower end of the carrying plate 2. The bottom of the four groups of slide bars 10 is fixed with a lifting plate 11. When the first cylinder 3 is started to extend, the lifting plate 11 is driven to move downward. During movement, the slide bar 10 can stabilize the lifting plate 11.

[0032] The clamping assembly includes a mounting block 12 fixed to the lower end of the lifting plate 11, and two groups of second cylinders 13 are fixed to the inner and outer side plates of the mounting block 12 respectively. A through groove is provided inside the mounting block 12, and two groups of clamping plates 16 are provided on both sides of the inner side of the through groove. The two groups are arranged in pairs to form a group, which are used to clamp the upper ridge 15 and the lower ridge 21 respectively. Each second cylinder 13 is connected to a clamping plate 16. When the lifting plate 11 descends, the upper ridge 15 and the lower ridge 21 pass through the through groove, and the second cylinder 13 is started to extend. The upper ridge 15 and the lower ridge 21 are clamped by the clamping plates 16 on both sides. After clamping, the first cylinder 3 is controlled to contract to drive the upper ridge 15 and the lower ridge 21 to move upward.

[0033] Two groups of cameras 17 are fixed below the lifting plate 11, and two groups of distance sensors 18 and two groups of cameras 24 are fixed on the inner wall of the through groove. Camera 17 is used to shoot the upper ridge 15 and the lower ridge 21, and camera 24 is used to detect whether the upper ridge 15 and the lower ridge 21 are offset. The distance sensor 18 is used to detect the distance between the inner wall of the mounting block 12 and the upper ridge 15 and the lower ridge 21 respectively; the camera 17, camera 2 24, and distance sensor 18 constitute a sensing detection unit.

[0034] Two sets of stop plates 8 are fixed to the top of the fixed plate 7. Each set of stop plates 8 is shaped like a trumpet with its opening facing upward, and is used to position the speaker housing 14. The stop plates 8 are symmetrically provided with notches to avoid the screw mounting locations connecting the upper ridge 15 and lower ridge 21 to the speaker housing 14. The two sets of stop plates 8 are arranged below two of the clamping assemblies, and are symmetrically arranged about the center of the fixed plate 7 and the chassis 1. The side surfaces of the stop plates 8 are threaded with fixing screws to further secure the speaker housing 14.

[0035] The movable assembly is provided in two groups, the center line connecting the two groups of movable assemblies being perpendicular to the center line connecting the two groups of limiting plates. The two groups of movable assemblies are symmetrically arranged about the center of the fixed plate 7 and the chassis 1, and the two groups of movable assemblies are respectively arranged below the other two groups of clamping assemblies. The movable assembly includes a conveyor belt 23, which is arranged above the chassis 1. A plurality of placement blocks 20 are fixed at equal intervals on the conveyor belt 23. The placement blocks 20 are used to place and position the upper ridge 15 and lower ridge 21 to be installed. The conveyor belt 23 is activated to move the placement blocks 20 below the clamping assembly. Typically, a positioning sensor can be provided on the conveyor belt 23 or the chassis 1 to control the conveying position of the placement blocks 20 according to the installation rhythm.

[0036] In this embodiment, a double-ridged horn receiving antenna installation device also includes a double-ridged installation control system and an automatic screw machine (not shown in the figure, the number is set according to needs), the automatic screw machine is arranged on the outside of the chassis 1, the double-ridged installation control system includes an installation control module and an installation detection module, the installation control module includes a movement control submodule, a rotation control submodule, a telescopic control submodule, a clamping control submodule and a screw fixing control submodule, the movement control submodule is electrically connected to the conveyor belt 23, and is used to control the movement of the conveyor belt 23, the rotation control submodule is electrically connected to the motor, and is used to control the rotation of the motor, thereby controlling the position of the clamping assembly, the telescopic control submodule is electrically connected to the first cylinder 3, and is used to control the telescopic movement of the first cylinder 3, the clamping control submodule is electrically connected to the second cylinder 13, and is used to control the telescopic movement of the second cylinder 13, and the screw fixing control submodule is electrically connected to the automatic screw machine, and is used to control the screwing action of the automatic screw machine;

[0037] The installation detection module includes an image receiving submodule, a distance receiving submodule, an analysis submodule, an alarm submodule and a marking submodule. The image receiving submodule is electrically connected to camera 1 17 and camera 2 24 , and the distance receiving submodule is electrically connected to the distance sensor 18 .

[0038] The dual-ridge mounted control system includes the following installation methods:

[0039] Step 1: Place the upper ridge 15 and the lower ridge 21 on the placement block 20, start the movement control submodule to control the conveyor belt 23 to move the placement block 20 to the bottom of the clamping assembly, and then place the speaker housing 14 into the limiting plate 8. Since the limiting plate 8 is in the shape of a trumpet with an opening upward, the speaker housing 14 is positioned without displacement. Then, the automatic screw machine intelligently rotates the fixing screws to fix the speaker housing 14 and the limiting plate 8 to ensure the stability of subsequent screw tightening;

[0040] Step 2: The telescopic control submodule controls the first cylinder 3 to extend and drive the clamping assembly downward. The clamping assembly is activated to control the second cylinder 13 to extend, so that the clamping plate 16 clamps the upper ridge 15 and the lower ridge 21. The first cylinder 3 is controlled to retract and move the upper ridge 15 and the lower ridge 21 out of the placement block 20.

[0041] It should be added that the clamping assembly located above another set of moving assemblies works simultaneously to clamp the upper ridge 15 and the lower ridge 21 together. When the upper ridge 15 and the lower ridge 21 are moved out of the placement block 20, the placement block 20 follows the conveyor belt 23 into the loop and continues to control the movement of the conveyor belt 23 to move the next placement block 20 with the upper ridge 15 and the lower ridge 21 to the bottom of the clamping assembly.

[0042] Step 3: Start the rotation control submodule, control the motor drive, drive the rotating disk 22 to rotate, and thereby drive the supporting disk 2 to rotate through the connecting column 6, move the clamped upper ridge 15 and lower ridge 21 to above the limit plate 8, extend the first cylinder 3 to drive the clamping assembly to move downward, insert the upper ridge 15 and lower ridge 21 into the speaker housing 14, and fix the upper ridge 15 and lower ridge 21 in the speaker housing 14 by rotating the screws with an automatic screw machine; then perform installation quality inspection.

[0043] Step 4: After the upper ridge 15 and the lower ridge 21 are completely fixed to the speaker housing 14, the automatic screw machine is controlled to rotate the fixing screws on the limit plate 8 in the opposite direction so that the fixing screws no longer limit the installed speaker housing 14. The finished product with the upper ridge 15 and the lower ridge 21 installed is removed, and a new speaker housing 14 is placed into the limit plate 8. The carrier plate 2 is rotated again to move the empty clamping assembly to the placement block 20. At the same time, the other set of clamping assemblies is also moved to the placement block 20. The upper ridge 15 and the lower ridge 21 are continued to be moved to the top of the speaker housing 14 through the clamping assembly, and the horn antenna is continued to be installed.

[0044] It should be noted that, since there are two sets of the limiting plates 8 and the moving components, and they are staggered, two sets of horn antennas can be assembled at the same time to improve work efficiency and replace manual operation.

[0045] Step 3 includes the following specific steps:

[0046] Step 3-a: Before the automatic screw machine starts working, align the threaded holes on the upper ridge 15 and the lower ridge 21 with the through holes of the speaker housing 14 by controlling the stroke of the first cylinder 3;

[0047] Specifically, as the staff follows the prescribed procedure, sets a prescribed distance in the telescopic submodule to control the stroke of the first cylinder 3, activates the second cylinder 13 to clamp the upper ridge 15 and the lower ridge 21 through the clamping plate 16, and then controls the first cylinder 3 to move the upper ridge 15 and the lower ridge 21 to the set distance, it indicates that the threaded holes on the upper ridge 15 and the lower ridge 21 are aligned with the through hole of the speaker housing 14;

[0048] Step 3-b: When starting the automatic screw machine, first install the screws in the two sets of threaded holes on the upper ridge 15 and the lower ridge 21 respectively. Check whether the positions of the upper ridge 15 and the lower ridge 21 change during the installation process, and determine the installation position. If the installation position does not change, continue to start the automatic screw machine to install all the screws;

[0049] Specifically, the automatic screw machine is first controlled to install the first and last screws on both sides of the speaker housing 14. After the two sets of threaded holes are installed with screws, the second cylinder 13 is controlled to contract through the clamping control submodule, so that the clamping plate 16 is away from the upper ridge 15 and the lower ridge 21 and no longer clamps. At this time, the distance sensor 18 respectively detects the distances L1 and L2 between the inner wall of the mounting block 12 and the upper ridge 15 and the lower ridge 21 (for the convenience of the following expression, L is used in the following, and the following L judgment can be made by satisfying either L1 or L2), and transmits the signal to the distance receiving submodule, compares it with the set distance, and determines whether the upper ridge 15 and the lower ridge 21 are offset after the first two sets of screws are installed.

[0050] When L (L1 or L2) is equal to the set distance or exceeds the set range, it means that the positions of the upper ridge 15 and the lower ridge 21 have not shifted during installation, and subsequent screws can be installed to continue fixing the upper ridge 15 and the lower ridge 21 to the speaker housing 14.

[0051] When L is not equal to the set distance and exceeds the set range, it means that the positions of the upper ridge 15 and the lower ridge 21 are offset during installation. It is necessary to further analyze the offset distance through the analysis sub-module. Specifically, the maximum offset distance is set to S in the analysis sub-module. When the offset distance is less than S, it means that the offset distance of the upper ridge 15 and the lower ridge 21 is within the allowable range. When the offset distance is equal to or greater than S, it means that there is a problem with the installation size of the upper ridge 15 and the lower ridge 21. At this time, the signal is transmitted to the alarm sub-module to alarm, so as to inform the staff to remove it.

[0052] When the offset distance between the upper ridge 15 and the lower ridge 21 is within the allowable range, the length of the offset is further determined. Specifically, the images of the upper ridge 15 and the lower ridge 21 after offset are captured by camera 2 24 and transmitted to the image receiving submodule. Since the un-offset images of the upper ridge 15 and the lower ridge 21 are set in the image receiving submodule, the real-time captured image is compared with the set image, and then the difference between the two is analyzed by the analysis submodule to identify the length of the offset.

[0053] The judgment formula is: Among them L 总 is the total longitudinal length of the upper ridge 15 or the lower ridge 21, L 偏 is the longitudinal length of the upper ridge 15 or the lower ridge 21 offset, L 占 It is the ratio of the offset length of the upper ridge 15 or the lower ridge 21 to the total length of the upper ridge 15 and the lower ridge 21.

[0054] When 0 <L 占 When it is ≤5%, it means that the offset length of the upper ridge 15 and the lower ridge 21 is short. Continue to start the automatic screw machine and install the next screw. After the installation is completed, use the distance sensor 18 to detect the distance again. If the distance difference is still within the allowable range, continue to install the next screw until the screw installation is completed. If the distance after installation is greater than S, it means that there is a problem with the installation size, which causes the position of the upper ridge 15 or the lower ridge 21 to be offset. At this time, an alarm is issued through the alarm sub-module.

[0055] When L 占 When it is greater than 5%, it indicates that the offset length of the upper ridge 15 or the lower ridge 21 is too long, and the signal is directly transmitted to the alarm submodule.

[0056] The above steps ensure the positions of the upper ridge 15 and the lower ridge 21 during the installation of the screws, avoid position deviation during installation, and improve installation accuracy.

[0057] Step 3-c: After the installation is completed, use camera 17 to photograph the upper ridge 15 and the lower ridge 21 to see if any deformation occurs after the installation is completed to ensure the quality of the double-ridged horn receiving antenna;

[0058] Specifically, after the installation is completed, the quality of the installation of the double-ridged horn receiving antenna is further determined by a pulling action. The second cylinder 13 is controlled to extend by the clamping control submodule so that the clamping plate 16 touches the upper ridge 15 and the lower ridge 21. The first cylinder 3 is then controlled to contract by the telescopic control submodule to drive the clamping assembly to move upward. When the installation block 12 moves upward, the clamping plate 16 will rub and pull the upper ridge 15 and the lower ridge 21 upward. The clamping plate 16 is always in contact with the upper ridge 15 and the lower ridge 21. After providing a set pulling force, the second cylinder 13 is controlled to contract so that the clamping plate 16 no longer clamps the upper ridge 15 and the lower ridge 21. At this time, a camera 17 takes a photo of the installed upper ridge 15 and the lower ridge 21 and transmits it to the image receiving submodule. Since the photo of the upper ridge 15 and the lower ridge 21 being installed properly is set in the image receiving submodule, the two are compared to determine the quality of the installation of the double-ridged horn receiving antenna. It is understandable that when determining whether an offset occurs, it can also be detected by a distance sensor.

[0059] Specifically, when the upper ridge 15 and the lower ridge 21 are not offset during installation, but the image comparison is inconsistent, it means that the upper ridge 15 and the lower ridge 21 are loose after being pulled upward, resulting in positional offset, indicating that there is a problem with the installation quality of the dual-ridged horn receiving antenna, and the problem is relatively serious. At this time, the signal is transmitted to the alarm submodule to issue an alarm. When the upper ridge 15 and the lower ridge 21 are offset by a short distance during installation, but the image comparison after installation is inconsistent, it means that there is a problem with the installation quality of the dual-ridged horn receiving antenna, but it is not serious. At this time, the signal is transmitted to the marking submodule for marking. A color mark is set in the marking submodule, and the installed horn receiving antenna is marked with the set color for display prompts, so that the staff can understand the installation status in real time, facilitate manual and timely adjustments, and always ensure the installation quality. If the upper ridge 15 and the lower ridge 21 are offset by a short distance during installation, but the image comparison is consistent, it means that the assembled dual-ridged horn receiving antenna is of good quality.

[0060] Through the above steps, the quality of the assembled double-ridged horn receiving antenna can be tested, further ensuring the stability of the performance and service life of the horn receiving antenna.

A method for installing a double-ridged horn receiving antenna, using the double-ridged horn receiving antenna installation device according to claims 1-6, characterized in that: include: Step 1: Place the upper and lower ridges on the moving assembly, control the moving assembly to move the upper and lower ridges to the bottom of the clamping assembly, place the speaker housing into the limit plate, and fix the speaker housing and the limit plate with an automatic screw machine; Step 2: Control the lifting assembly to drive the clamping assembly to move downward, start the clamping assembly to clamp the upper and lower ridges, and then move upward to separate the upper and lower ridges from the moving assembly; continue to control the moving assembly to move the next set of upper and lower ridges to the bottom of the clamping assembly; Step 3: Control the rotating assembly to rotate, drive the carrier plate to rotate, move the clamped upper and lower ridges to above the limit plate, control the lifting assembly to drive the clamping assembly to move downward, insert the upper and lower ridges into the speaker housing, and use the automatic screw machine to rotate the screws to fix the upper and lower ridges in the speaker housing; then perform the installation quality inspection; Step 4: Control the automatic screw machine to reversely rotate the fixing screws on the limit plate, remove the finished product, then place a new speaker housing into the limit plate and continue installing the next speaker antenna.

8. The method for installing a double-ridged horn receiving antenna according to claim 7, wherein: During the installation of the upper and lower ridges to the speaker housing, the threaded holes on the upper and lower ridges are aligned with the through holes of the speaker housing by controlling the travel of the lifting assembly; When starting the automatic screw machine, first install the screws on the two sets of threaded holes on the upper and lower ridges respectively, and check whether the positions of the upper and lower ridges change during the installation process. The installation quality inspection includes judging the installation position. When the installation position has not changed, continue to start the automatic screw machine to install all the screws.

9. The method for installing a double-ridged horn receiving antenna according to claim 8, wherein: Determining the installation location specifically includes: First, the automatic screw machine is controlled to install the first and last screws on both sides of the speaker housing. The distance detected by the sensor detection unit is compared with the set distance to determine whether the upper and lower ridges are offset, thereby controlling whether the automatic screw machine continues to tighten the screws. If the detected distance is less than the set distance, the subsequent screws are installed. If the detected distance is not less than the set distance, the offset length is further determined through image comparison: Among them L 总 is the total longitudinal length of the upper or lower ridge, L 偏 is the longitudinal length of the upper or lower ridge offset, L 占 is the ratio of the length of the upper or lower ridge offset to the total length of the upper or lower ridge; when 0 <L 占 ≤5%, continue to tighten the next screw. If the offset length is within the set range, continue to tighten the next screw and repeat the distance detection, image shooting, offset judgment and offset length comparison until all screws are installed. If L 占 If it is >5%, it means there is a problem with the installation size.

10. The method for installing a double-ridged horn receiving antenna according to claim 7, wherein: The installation quality inspection also includes pulling the upper and lower ridges to determine whether they are loose and cause positional deviation, and the degree of deviation. The quality of the double-ridged horn receiving antenna installation is judged by taking images of the installed upper and lower ridges and comparing them with images of qualified installation: when the positions of the upper and lower ridges do not shift during installation, but the compared images are inconsistent, it means that the upper and lower ridges become loose after being pulled upward, resulting in position shift, indicating that there is a problem with the installation quality of the double-ridged horn receiving antenna, and it is relatively serious; when the offset distance of the upper and lower ridges is short during installation, but the compared images after installation are inconsistent, it means that there is a problem with the installation quality of the double-ridged horn receiving antenna, but it is not serious, and a prompt will be displayed; when the offset distance of the upper and lower ridges is short during installation, but the compared images are consistent, it means that the assembled double-ridged horn receiving antenna is of good quality.
