Description

Technical Field

[0001] The invention relates to the technical field of packaged antenna testing equipment, in particular to an adaptive antenna packaging performance testing device. Background Art

[0002] As wireless communications move from 2G to 5G and the future 6G, the performance requirements for packaged antennas have increased dramatically. They are widely used in many fields such as mobile phones and base stations, and the requirements for different scenarios vary. The current electromagnetic environment is complex, interference is frequent, and the contradiction between antenna miniaturization and high performance is prominent. The miniaturization of electronic equipment has led to a reduction in antenna size, but performance cannot be sacrificed. In production, in order to ensure consistent quality and improve production efficiency, it is necessary to control quality through performance testing, promptly discover and resolve production defects, and meet the stringent requirements of communication development for high performance and high reliability of packaged antennas.

[0003] Currently, the RF performance test of the antenna after packaging is mostly carried out in a microwave darkroom. The conventional practice is to fix the packaged antenna on a special test platform and rotate it, and then test it with a reference antenna that is stationary at a distance. However, this method is seriously inconsistent with actual working conditions.

[0004] In daily use, the packaged antenna is usually fixed to receive signal sources from all directions, rather than rotating itself to receive nearby RF signals. At the same time, the accuracy and efficiency of testing with only a single-axis rotation are poor, so multi-axis rotation should be set for testing.

[0005] Furthermore, vibration will affect antenna performance during actual operation, but existing test equipment cannot perform vibration detection simultaneously during rotation testing, and urgently needs to be optimized to suit actual application scenarios.

[0006] In addition, when testing packaged antennas, they are often fixed on a dedicated test platform. At present, manual bundling or simple clamping mechanisms are generally used to achieve fixed clamping. However, this method has obvious disadvantages. It is difficult to effectively fix packaged antennas of different sizes and shapes. Antennas with irregular shapes are prone to unstable fixation, and antennas with large size deviations may not be able to adapt, causing the antenna to shake or move during the test, seriously affecting the accuracy and reliability of the test results.

Detailed Description of the Invention

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific embodiments and the accompanying drawings.

[0040] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention, but these terms may change according to the intentions of those of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0041] Refer to Figure 1, this embodiment provides an adaptive antenna package performance testing device, including a workbench 1, a test clamp 2, a vertical rotation mechanism 3, a horizontal rotation mechanism 4, and a vibration generating unit 5. A protective housing for protection is provided outside the workbench 1.

[0042] Referring to Figures 1 - 3 , the test clamp 2. The top of the test clamp 2 is equipped with an adaptive clamping component 21 for firmly clamping packaged antennas of different sizes to ensure the position stability of the packaged antenna during the test.

[0043] In use, the test clamp 2 is integrally formed of a high-strength metal alloy material, having excellent structural strength and stability, and being able to resist various stresses generated during the test without deformation.

[0044] Referring to Figure 1 、 Figure 9 and Figure 11 , the vertical rotation mechanism 3 is centrally fixed inside the workbench 1 below the test clamp 2 for driving the test clamp 2 to rotate along the vertical axis direction to realize the rotation test of the packaged antenna fixed on the adaptive clamping component 21.

[0045] Referring to Figure 1 and Figure 8 , the horizontal rotation mechanism 4 is installed outside the workbench 1. The rotating end of the horizontal rotation mechanism 4 is connected with a reference antenna 41. The horizontal rotation mechanism 4 is used to drive the reference antenna 41 to make a circumferential rotation movement around the packaged antenna in the horizontal axis direction.

[0046] In use, after the antenna is packaged, the packaged antenna is placed on the test clamp 2, and then starts to receive the radio frequency signal emitted by the reference antenna 41 to realize the test of its radio frequency performance.

[0047] When the horizontal rotation mechanism 4 is running, it will synchronously drive the reference antenna 41 to rotate in the horizontal axis direction. Compared with the traditional test method in which the reference antenna 41 is fixed and only the test packaged antenna is rotated, this test method of rotating the reference antenna 41 can more accurately simulate the working conditions faced by the packaged antenna during actual use. In the actual application scenario, the signal source often dynamically changes around the antenna. By rotating the reference antenna 41, this real situation can be highly restored, and thus a better and more accurate radio frequency test effect can be obtained.

[0048] At the same time, the vertical rotating mechanism 3 can rotate the packaged antenna in the vertical axis. Through this design, the packaged antenna and the reference antenna 41 can respectively realize multiple axial rotations in different axes. This test method of simultaneous rotation in multiple axes improves the test accuracy of the packaged antenna. On the one hand, simultaneous rotation in multiple axes can cover a wider angle range and comprehensively detect the performance of the antenna in different directions; on the other hand, it effectively reduces the limitations caused by single-axis rotation testing and avoids missing potential performance problems, thereby significantly improving the test efficiency and providing a strong guarantee for the rapid and accurate evaluation of the performance of the packaged antenna.

[0049] Reference Figure 9 and Figure 10 The vibration generating unit 5 is installed inside the workbench 1 and is symmetrically installed around the vertical rotating mechanism 3. The vibration generating unit 5 includes a driving component 51, a synchronization component 52, and a vibration platform 53 installed at the top output port of the driving component 51. The vibration generating unit 5 is used to drive the packaged antenna fixed on the adaptive clamping component 21 to perform a vibration test.

[0050] During use, the vibration generating unit 5 is used to simulate vibration and perform real-time vibration testing on the packaged antenna, simulating the vibration environment that the antenna may encounter in actual use. At the same time, by starting and stopping the vibration generating unit 5, the operator can independently choose whether to perform vibration testing while testing the RF performance of the packaged antenna according to specific test requirements, so that the entire test system can automatically adapt to diverse test process requirements, whether it is the evaluation of the RF performance of the antenna in a stable environment or the test of its anti-interference ability in a vibration environment, it can automatically adapt to the test requirements, thereby improving the test efficiency and accuracy.

[0051] Reference Figures 2 - 6 The adaptive clamping assembly 21 includes a disc 211 rotatably connected to the test clamp 2, and a plurality of arc grooves 212 with the same structure and uniformly distributed in a circular ring shape around the center of the disc 211 are formed on the disc 211. A slidable guide column 213 is adapted in each arc groove 212, and a corresponding extrusion rod 214 is connected to the top of each guide column 213. All extrusion rods 214 are slidably connected to a guide disc 215 fixed to the outer shell of the test clamp 2.

[0052] Reference Figure 7 The extrusion rod 214 includes a sliding block 2141 that slides on the guide plate 215, and a clamping rod 2142 is slidably connected inside the sliding block 2141. The clamping rod 2142 is connected to the sliding block 2141 through a compression spring 2143, and a clamping end 2144 is rotatably connected to the end of the clamping rod 2142 away from the compression spring 2143.

[0053] In use, the disc 211 can rotate flexibly on the test holder 2. When the disc 211 rotates, it will drive a plurality of guide posts 213 located in the arc-shaped grooves 212 to move synchronously. The top end of each guide post 213 is connected to an extrusion rod 214. These extrusion rods 214 are neatly distributed in a circular ring around the disc 211. As the guide posts 213 move, the plurality of extrusion rods 214 are constrained in their movement directions by the guide disc 215, so that the plurality of extrusion rods 214 move synchronously towards the center position of the disc 211 and apply an extrusion force, thereby realizing effective clamping of the packaged antenna placed on the disc 211 (refer to Figure 12 ), so that packaged antennas of different sizes can be clamped, showing good versatility.

[0054] In addition, the clamping rod 2142 is connected to the sliding block 2141 through a compression spring 2143, so that the clamping rod 2142 can be elastically compressed inside the sliding block 2141 along the reverse clamping direction. When encountering a packaged antenna with an irregular shape, one or several extrusion rods 214 can adjust their positions according to the actual shape of the antenna through the compression deformation of the compression spring 2143, so that the plurality of extrusion rods 214 can maintain the clamping force together and reserve a necessary clamping space for other extrusion rods 214, so that packaged antennas of different shapes can be clamped, ensuring a stable and reliable clamping effect. In addition, the clamping end 2144 can rotate on the clamping rod 2142, which not only expands the clamping area of a single point of the extrusion rod 214, but also can better fit the outer surface of packaged antennas of different shapes, further improving the stability and reliability of clamping.

[0055] Refer to Figure 2 、 Figure 3 、 Figure 9 and Figure 11 , the vertical rotation mechanism 3 includes a first motor 31 arranged on the inner bottom surface of the workbench 1. The output end of the first motor 31 is rigidly connected vertically upward with a spline shaft 32. The spline shaft 32 is axially slidably connected with a transmission rod 34 through a spline shaft sleeve 33 adapted to it.

[0056] Refer to Figure 2 and Figure 3 , the top end of the transmission rod 34 is connected to the upper disc 211 by setting a torque limiter 35.

[0057] In use, the first motor 31 drives the spline shaft 32 to rotate. The spline shaft 32 drives the transmission rod 34 to rotate synchronously. The transmission rod 34 drives the disc 211 to rotate together, so that the packaged antenna can be rotated upward in the vertical axis direction and the radio frequency performance can be tested.

[0058] In addition, the fit between the spline shaft 32 and the spline bushing 33 reserves sufficient space for the follow-up movement of the transmission rod 34 and the vibration generating unit 5, ensuring that there will be no direct movement interference when the vertical rotation mechanism 3 and the vibration generating unit 5 operate simultaneously, and guaranteeing the stability of the equipment operation.

[0059] In addition, the first motor 31 has dual functions: on the one hand, it provides power for the rotational movement of the encapsulated antenna in the vertical axis direction; on the other hand, by driving the rotating disk 211, it prompts multiple pressing rods 214 to simultaneously apply a pressing force to the encapsulated antenna in the center, realizing firm clamping. To prevent interference between the transmission rod 34 and the disk 211 during movement due to excessive rotation, a torque limiter 35 is specially provided at their connection. When the pressing rods 214 complete the clamping of the encapsulated antenna, the disk 211 stops rotating, while the transmission rod 34 still maintains a rotating state. At this time, since the encapsulated antenna is already in a fastened state, the excess rotational torque of the transmission rod 34 will be released in a timely manner through the torque limiter 35, effectively avoiding movement interference between the transmission rod 34 and the stationary disk 211, and ensuring the safe and stable operation of the entire test process.

[0060] Moreover, using the first motor 31 as the power source for the two functions greatly reduces the motor purchase cost compared to using multiple independent motors for separate driving.

[0061] Refer to Figure 1 and Figure 8 , the horizontal rotation mechanism 4 includes a supporting plate 42 fixed to the outside of the workbench 1. A ring gear support 43 is fixed on the supporting plate 42. A rotatable ring gear 44 is arranged inside the ring gear support 43. Two gears 45 are mirror-symmetrically arranged inside the ring gear support 43. The ring gear 44 meshes with the two gears 45. Both of the two gears 45 are rotatably connected inside the ring gear support 43. One of the gears 45 is connected to the output end of a second motor 46 arranged outside the ring gear support 43; a reference antenna 41 is detachably connected to the side of the ring gear 44 close to the encapsulated antenna.

[0062] During use, the second motor 46 drives the gear 45 to rotate. The gear 45 drives the ring gear 44 to rotate inside the ring gear support 43, thereby driving the reference antenna 41 that emits radio frequency signals on the ring gear 44 to rotate around the encapsulated antenna, and then better simulating the working conditions faced by the encapsulated antenna during actual use.

[0063] Refer to Figure 10, the driving assembly 51 includes a third motor 511 disposed on the inner bottom surface of the workbench 1. Two crankshafts 512 are rotatably disposed inside the workbench 1 through supports. The output end of the third motor 511 is connected to one of the crankshafts 512. Connecting rods 513 are rotatably connected to the outside of the two crankshafts 512. The connecting rods 513 are rotatably connected to the vibration ejector rods 514 above. The vibration ejector rods 514 are slidably connected to the guide plates 515. There are two guide plates 515, both of which are fixed to the inner wall of the workbench 1. The top end of the vibration ejector rod 514 is connected to a vibration platform 53.

[0064] Refer to Figure 10 , the synchronization assembly 52 includes two synchronizing wheels 521 disposed at the ends of the two crankshafts 512. A synchronous belt 522 is sleeved on the two synchronizing wheels 521 together.

[0065] Refer to Figure 9 and Figure 10 , two guide rods 516 parallel to the vibration ejector rods 514 are also slidably connected to the guide plates 515 on both sides of the vibration ejector rods 514. Buffer springs 517 are sleeved on the rod bodies of the vibration ejector rods 514 between the guide plates 515 and the vibration platform 53 and on the rod bodies of the guide rods 516.

[0066] Refer to Figure 2 and Figure 11 , a vibration auxiliary bracket 54 is fixed to the bottom of the vibration platform 53. A transmission rod sleeve 55 is rotatably connected to the inside of the vibration auxiliary bracket 54. The top end of the transmission rod sleeve 55 is fixedly connected to the bottom of the test clamp seat 2; a transmission rod 34 is also rotatably connected to the inside of the transmission rod sleeve 55, and the transmission rod 34 is longer than the transmission rod sleeve 55 in size. Both ends of the transmission rod 34 extend out of the transmission rod sleeve 55; at the rotational connection of the vibration auxiliary bracket 54 and the transmission rod sleeve 55, and at the rotational connection of the transmission rod sleeve 55 and the transmission rod 34, limit mechanisms for preventing the rotating connecting member from sliding downward along the axial direction are provided.

[0067] During use, after the third motor 511 is started, it drives the crankshaft 512 to rotate. The rotation of the crankshaft 512 drives the connecting rod 513 to make a reciprocating up and down motion, and further enables the vibration ejector rod 514 to drive one side of the vibration platform 53 to vibrate up and down. At the same time, through the two synchronizing wheels 521 and the synchronous belt 522, power transmission is achieved between the other crankshaft 512 and the connecting rod 513, ensuring that both sides of the vibration platform 53 can vibrate synchronously.

[0068] The transmission rod sleeve 55 is rotatably connected inside the vibration auxiliary bracket 54, and the transmission rod 34 is rotatably connected inside the transmission rod sleeve 55. The transmission rod 34 and the transmission rod sleeve 55 can rotate around the vertical axis, and the two form a rotational connection along the axis. The up and down sliding displacement of the transmission rod 34 and the transmission rod sleeve 55 along the axial direction is restricted by the limit structure, enabling it to only rotate around the axis in the vertical direction.

[0069] Based on this, the vibration platform 53 can drive the transmission rod sleeve 55 and the transmission rod 34 to vibrate up and down through the vibration auxiliary bracket 54, and transfer the vibration to the packaged antenna under test. This enables the packaged antenna to not only perform rotational tests simultaneously in multiple axial directions, but also carry out vibration tests synchronously according to actual needs.

[0070] In addition, the design of the transmission rod sleeve 55 and the vibration auxiliary bracket 54 increases the contact area between the transmission rod 34 and the vibration platform 53, improves the connection stability, and thus plays a protective role for the transmission rod 34.

[0071] In addition, the limiting mechanism for preventing the rotating connecting piece from sliding downward along the axial direction is an existing structure and will not be specifically described here.

[0072] On the side of the vibration ejector rod 514 close to the vibration platform 53, a telescopic rod structure is adopted and a buffer spring 517 is provided. This forms an elastic connection between the connecting rod 513 and the vibration platform 53. This connection method can effectively buffer and dampen vibrations, greatly reducing the wear of each component of the device. In addition, guide rods 516 are additionally provided on both sides of the vibration ejector rod 514, and buffer springs 517 are also sleeved on the guide rods 516. The vibration ejector rod 514 is slidably connected to the guide plate 515 through the fixedly connected guide rods 516. The guide plate 515 restricts their movement directions, enabling them to only slide up and down along the axial direction of the transmission rod 34, further enhancing the damping effect.

[0073] In addition, the transmission structure composed of the synchronous pulley 521 and the synchronous belt 522 can also be replaced by other components with synchronous power transmission functions such as a chain and sprocket structure in practical applications.

[0074] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
