Detailed Implementation

[0054] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0055] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0056] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0057] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0058] The testing equipment involved in this application embodiment can be a mobile phone, smartwatch, tablet computer, or other device with a wireless antenna, and this application embodiment does not impose specific limitations on it. The following description uses a mobile phone as an example.

[0059] Currently, mobile phone radio frequency performance testing is increasingly focused on testing the overall radiation performance of the device, which reflects the phone's final transmission and reception performance. There are currently two main methods for examining the radiation performance of mobile phones: one is to determine it from the antenna's radiation performance, which is the more traditional antenna testing method, called passive testing; the other is to test the phone's radiated power and receiving sensitivity in a specific microwave anechoic chamber, called active testing.

[0060] Passive testing focuses on examining the radiation performance of a mobile phone by considering its antenna radiation parameters, such as gain, efficiency, and radiation pattern. Although passive testing takes into account the impact of the overall environment (such as components around the antenna, and whether the phone is open or closed) on antenna performance, the final radiated transmit power and receive sensitivity after the antenna is integrated with the entire device cannot be directly determined from the passive test data, making the test data not very intuitive.

[0061] Active testing focuses on examining the radiation performance of a mobile phone by measuring its overall transmission power and reception sensitivity. Active testing is conducted in a specific microwave anechoic chamber, measuring the transmission power and reception sensitivity of the entire device in all three directions, thus providing a more direct reflection of the phone's overall radiation performance.

[0062] The CTIA (Cellular Telecommunication and Internet Association) has established relevant standards for OTA (Over-The-Air) testing. OTA testing focuses on the overall radiation performance of the device and is gradually becoming a testing item that mobile phone manufacturers value and recognize.

[0063] Currently, only mobile phone models that have passed FTA (Full Type Approval) certification testing can be sold on the market. In FTA testing, radio frequency performance testing mainly focuses on the phone's radio frequency performance in cable connection mode. However, the overall radiation emission and reception performance of the phone is not explicitly defined in FTA testing, and OTA testing fills this gap. At the same time, terminal manufacturers must have a clear understanding of the radiation performance of the phones they produce and take various measures to improve the phone's emission and reception indicators. Poor radiation performance will result in problems such as poor phone signal, poor voice call quality, and frequent dropped calls, which are common customer complaints.

[0064] During a mobile phone call, the human brain is close to the phone's antenna, which reduces the phone's transmission and reception performance, thus lowering the overall transmission and reception performance of the phone. During mobile phone development, the impact of the human brain on the phone's transmission and reception performance should be quantitatively measured to optimize the design and minimize the reduction in performance, i.e., reducing the electromagnetic coupling effect between the human body and the antenna.

[0065] To assess the radiation performance of a mobile phone, in addition to examining the passive performance of the antenna, the active performance of the entire device is also an important aspect. Currently, terminal manufacturers are paying increasing attention to the active performance of the entire device; therefore, both types of radiation performance should be considered together when evaluating mobile phone radiation performance. At present, terminal antenna manufacturers generally require antenna suppliers to provide both passive and active test reports during the R&D process.

[0066] However, current antenna testing technology only allows one phone to be tested at a time, requiring manual intervention to replace the phone during testing. This is especially problematic when there are many test samples, impacting project progress.

[0067] To address the aforementioned issues, this application provides an antenna testing system that can automatically test antennas from multiple devices without manual intervention, thereby improving testing efficiency. A detailed description is provided below with reference to the accompanying drawings.

[0068] Figure 1 This is a three-dimensional structural diagram of an antenna testing system provided in an embodiment of this application. Figure 2 An exploded view of an antenna testing system provided in an embodiment of this application. Figure 1 and combined Figure 2 As shown, the antenna testing system includes a gimbal, an antenna coil 210, and a test platform 220.

[0069] Specifically, the gimbal includes a support unit 140, which includes a first support frame 141 and a second support frame 142, connected by a pivot. The first support frame 141 and the second support frame 142 have a top plate 143 at their top and a bottom plate 144 at their bottom. It is understood that when the first support frame 141 and the second support frame 142 rotate relative to each other, the distance between the top plate 143 and the bottom plate 144 changes.

[0070] A workbench 110 is provided on the top plate 143. It is understood that the height of the workbench 110 will change when the first support frame 141 and the second support frame 142 rotate relative to each other. Of course, in some possible implementations, the supporting unit 140 may not include the top plate 143 and the floor, and the workbench 110 can be directly fixed to the first support frame 141 and the second support frame 142. This application embodiment does not limit this.

[0071] The workbench 110 is equipped with a prototype storage area 111, a transmission unit 120, and a gripping unit 130. The prototype storage area 111 is used to store test prototypes (e.g., mobile phones). It is understood that the prototype storage area 111 can store multiple test prototypes simultaneously, such as 5 or 8, the specific number depending on the space available in the prototype storage area 111. The transmission unit 120 is mounted on the workbench 110, and the gripping unit 130 is mounted on the transmission unit 120. The transmission unit 120 is used to drive the gripping unit 130 to move in three-dimensional space. For example, the transmission unit 120 can move the gripping unit 130 to the prototype storage area 111 to grip or place a test prototype in the prototype storage area 111.

[0072] Figure 3This is a schematic diagram of a transmission unit provided in an embodiment of this application. Figure 3 As shown, the transmission unit 120 includes a first-dimensional transmission mechanism 121, a second-dimensional transmission mechanism 122, and a third-dimensional transmission mechanism 123. The first-dimensional transmission mechanism 121 drives the gripping unit 130 to move in the first dimension, the second-dimensional transmission mechanism 122 drives the gripping unit 130 to move in the second dimension, and the third-dimensional transmission mechanism 123 drives the gripping unit 130 to move in the third dimension. It is understood that the first, second, and third dimensions are perpendicular to each other. That is, through this transmission unit 120, the gripping unit 130 can be moved to any point in the three-dimensional space (within its travel range). It is understood that in order to grip and place test prototypes in the prototype storage area 111 and the test platform 220, this three-dimensional space should cover both the prototype storage area 111 and the test platform 220.

[0073] Specifically, the first-dimensional transmission mechanism 121 is disposed on the workbench 110, the second-dimensional transmission mechanism 122 is disposed on the first-dimensional transmission mechanism 121, the third-dimensional transmission mechanism 123 is disposed on the second-dimensional transmission mechanism 122, and the gripping unit 130 is disposed on the third-dimensional transmission mechanism 123.

[0074] Of course, those skilled in the art can adopt other configurations according to actual needs. For example, the second-dimensional transmission mechanism 122 can be mounted on the worktable 110, the first-dimensional transmission mechanism 121 can be mounted on the second-dimensional transmission mechanism 122, the third-dimensional transmission mechanism 123 can be mounted on the first-dimensional transmission mechanism 121, and the gripping unit 130 can be mounted on the third-dimensional transmission mechanism 123; or, the third-dimensional transmission mechanism 123 can be mounted on the worktable 110, the second-dimensional transmission mechanism 122 can be mounted on the third-dimensional transmission mechanism 123, the first-dimensional transmission mechanism 121 can be mounted on the second-dimensional transmission mechanism 122, and the gripping unit 130 can be mounted on the first-dimensional transmission mechanism 121. This application does not impose specific limitations in this regard.

[0075] exist Figure 3 In the implementation shown, the first-dimensional transmission mechanism 121, the second-dimensional transmission mechanism 122, and the third-dimensional transmission mechanism 123 all employ screw and nut transmission mechanisms. It can be understood that, in addition to screw and nut transmission mechanisms, gear and rack transmission mechanisms, linear motor transmission mechanisms, pneumatic cylinder transmission mechanisms, and hydraulic cylinder transmission mechanisms can also be used to achieve linear motion.

[0076] In addition to using three mutually perpendicular linear transmission structures to realize the movement of the gripping unit 130 in the set three-dimensional space, those skilled in the art can also use two mutually perpendicular linear transmission mechanisms or other transmission mechanisms to realize the movement of the gripping unit 130 in the set line. This application embodiment does not impose specific limitations on this.

[0077] Figure 4 This is a three-dimensional structural diagram of a gripping unit provided in an embodiment of this application. Figure 4 As shown, the gripping unit 130 includes a robotic arm 131, on which are mounted a first robotic arm connector 132, a second robotic arm connector 133, a first robotic gripper 134, and a second robotic gripper 135. One end of the first robotic arm connector 132 is pivotally connected to the robotic arm 131, and the other end is pivotally connected to the first robotic gripper 134. One end of the second robotic arm connector 133 is pivotally connected to the robotic arm 131, and the other end is pivotally connected to the second robotic gripper 135. This connection method allows for the control of opening or closing the first robotic gripper 134 and the second robotic gripper 135.

[0078] Among them, the first robotic gripper 134 and the second robotic gripper 135 are in the following open states: Figure 5A As shown; the first robotic gripper 134 and the second robotic gripper 135 are in the closed state as follows. Figure 5B As shown. In practical applications, when it is necessary to grasp a test sample, the grasping unit 130 can be moved to the corresponding position (e.g., the sample storage area 111 or the test platform 220) in the open state, so that the test sample is located between the open first robotic gripper 134 and the second robotic gripper 135. Then, the first robotic gripper 134 and the second robotic gripper 135 are controlled to close, so that the first robotic gripper 134 and the second robotic gripper 135 clamp the test sample, and then the test sample can be moved to the target position (e.g., the test platform 220 or the sample storage area 111). After the test sample is moved to the target position, the first robotic gripper 134 and the second robotic gripper 135 are controlled to open, so that the first robotic gripper 134 and the second robotic gripper 135 release the test sample and place the test sample at the target position.

[0079] Understandable Figure 4 This is merely an illustrative example of this application. Those skilled in the art can set up other types of robotic arms 131 for grasping test prototypes according to actual needs, such as 3-jaw robotic arms or 4-jaw robotic arms, etc., all of which should fall within the protection scope of this application.

[0080] Please continue reading. Figure 1 and Figure 2The antenna testing system provided in this application embodiment also includes an antenna coil 210 and a test platform 220. Those skilled in the art will understand that the antenna coil 210 comprises multiple radio frequency modules arranged in a circular pattern; for ease of description, it is simply referred to as antenna coil 210 in this application embodiment. Specifically, the antenna coil 210 is connected to a test instrument for performing relevant tests on the prototype under test. The test instrument may include a comprehensive test instrument, a spectrum analyzer, etc.

[0081] In one possible implementation, the test platform 220 is a turntable 221, which is used to rotate the test prototype. The axis of rotation of the turntable 221 is parallel to the plane where the antenna coil 210 is located. The purpose of this arrangement is that by rotating the test prototype with the turntable 221, the radio frequency performance of the entire spherical area centered on the test prototype can be tested. Specifically, after completing the antenna test at the first angular position, the turntable 221 can be controlled to rotate a certain angle (e.g., 15°, 25°, etc.) to reach the second angular position, where the antenna test is performed; and so on, until a 360° angular range is covered.

[0082] It is understood that some electronic components (e.g., sensors, drive motors, etc.) exist on the workbench 110. During antenna testing, these electronic components can cause some interference. Therefore, the carrying unit 140 provided in this embodiment is used to move the workbench 110 to a second position point before and / or after testing. This second position point is close to the test platform 220 so that the gripping unit 130 can grip the test sample. After the gripping unit 130 completes gripping the test sample, the workbench 110 is moved to a first position point away from the test platform 220 to avoid interfering with the testing process.

[0083] See Figure 6 This is a schematic diagram illustrating a scenario with a first position point and a second position point, as provided in an embodiment of this application. In this application scenario, the first position point and the second position point are two position points in the vertical direction. In other words, the supporting unit 140 drives the platform to reciprocate between the first position point and the second position point in the vertical direction. Of course, those skilled in the art can, as needed, set the first position point and the second position point as two positions in the horizontal direction, wherein the first position point is horizontally away from the test platform 220 to avoid interfering with the testing process; the second position point is horizontally close to the test platform 220 so that the gripping unit 130 can grip the test prototype. Alternatively, the first position point and the second position point can be set in a combination of horizontal and vertical directions, and this embodiment of the application does not limit this.

[0084] See Figure 7This is a system block diagram of an antenna testing system provided in an embodiment of this application. Figure 7 As shown, the antenna testing system includes a control computer, which is electrically connected to the transmission unit 120, the gripping unit 130, the carrying unit 140, the turntable 221, the antenna switch, the input / output switch, the comprehensive test instrument, and the spectrum analyzer.

[0085] The control computer can send corresponding control commands to the transmission unit 120, causing the transmission unit 120 to drive the gripping unit 130 to move to the corresponding position; the control computer can send corresponding control commands to the gripping unit 130, causing the gripping unit 130 to perform gripping or releasing operations; the control computer can send corresponding control commands to the carrying unit 140, causing the carrying unit 140 to drive the worktable 110 to move to the first position point or the second position point; the control computer can send corresponding control commands to the turntable 221, causing the turntable 221 to rotate the test prototype by a certain angle; the control computer can send corresponding control commands to the antenna switch (used to control the antenna switch of the antenna coil 210), causing the corresponding radio frequency module in the antenna coil 210 to turn on or off; the control computer can send corresponding control commands to the input / output switch, causing the test prototype and the antenna coil 210 to transmit or disconnect information; the control computer can send the collected information to the comprehensive test instrument and the spectrum analyzer to complete the corresponding test and analysis work.

[0086] Based on the antenna testing system described above, this application also provides an antenna testing method.

[0087] See Figure 8 This is a schematic flowchart of an antenna testing method provided in an embodiment of this application. This method can be applied to the aforementioned antenna testing system, such as... Figure 8 As shown, the main steps include the following steps.

[0088] Step S801: Before the test, the support unit moves the worktable from the first position point to the second position point.

[0089] For example, in Figure 6 In the application scenario shown, the support unit moves the workbench from the bottom to the top, that is, to the height corresponding to the test platform.

[0090] Step S802: The grabbing unit grabs the test prototype in the prototype storage area and places the test prototype on the test platform.

[0091] Specifically, the transmission unit moves the gripping unit to the prototype storage area; the gripping unit grips the test prototype in the prototype storage area; the transmission unit moves the gripping unit to the test platform; and the gripping unit places the test prototype on the test platform.

[0092] Step S803: The bearing unit moves the worktable from the second position point to the first position point.

[0093] For example, in Figure 6 In the application scenario shown, the support unit moves the workbench from the top to the bottom to avoid interference from the electronic components in the workbench during the test.

[0094] Step S804: After the test is completed, the bearing unit moves the worktable from the first position point to the second position point.

[0095] After the test is completed, the workbench is moved from the first position point to the second position point so that the test prototype can be replaced and the next test prototype can be tested.

[0096] Step S805: The grabbing unit grabs the test prototype on the test platform and places the test prototype in the prototype storage area.

[0097] Specifically, the transmission unit moves the gripping unit to the test platform; the gripping unit grips the test prototype on the test platform; the transmission unit moves the gripping unit to the prototype storage area; and the gripping unit places the test prototype in the prototype storage area.

[0098] If there are still untested test prototypes in the prototype storage area, return to step S802 to continue testing the next test prototype; otherwise, end the entire testing process.
