Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of antenna testing devices, and in particular relates to an antenna testing device and antenna testing equipment. Background Technology
[0002] During the production and testing of electronic products, it is usually necessary to make an electrical connection between the test board and the power supply terminal of the workpiece under test in order to test whether the internal functions and signals of the electronic product meet the shipping requirements.
[0003] In existing technologies, the test board and the workpiece under test are usually set parallel to each other so that when connecting electronic products, the test end of the test board can be directly connected to the feed end of the electronic product for measurement. However, some electronic products are special, and the product feed point can only be set perpendicular to the test board. In particular, for some special antennas, such as those with the radiation direction and feed point in the same direction, the method of setting the test end of the test board and the feed point of the product in parallel and connecting them cannot be used on such products. Moreover, if the test end of the test board and the feed point of the electronic product are connected in a perpendicular manner, it will cause signal instability.
[0004] In other existing technologies, wires are often used to connect the test terminals of the test board and the power supply points of electronic products to improve the flexibility of the connection. However, this method requires manual connection. In the process of automated production, manual connection will result in low automation and very low testing efficiency. In addition, manual connection is prone to failure, which will lead to test errors. Utility Model Content
[0005] To address the aforementioned issues, this invention proposes an antenna testing device and equipment. By employing a conductive component, the device connects the product's feed end and the test board's feed end via the conductive component when pressed down. This allows for automated testing of the vertically positioned test board's test end and the product's feed end, thereby avoiding the problem that traditional testing methods cannot test the vertically positioned test board's test end and the product's feed end.
[0006] The objective of this utility model is achieved through the following technical solution:

[0010] The conductive part is provided with a first conductive area and a second conductive area, which are perpendicular to each other. The feed point of the workpiece is set on the periphery of the test position. After being pressed down by the pressing mechanism, the first conductive area is connected to the test end of the test board, and the second conductive area is connected to the feed point of the workpiece.
[0011] The testing device includes a testing platform with a workpiece mounting position for fixing the workpiece. The workpiece mounting position has multiple testing positions.

[0016] In some implementations, a signal output port is provided on one side of the test board, and a test connection port is provided on the test machine. The signal output port is aligned with the test connection port so that the test board transmits signals outward.
[0017] By aligning the signal output port and test connection port on one side of the test board, test signals can be transmitted outwards.
[0018] In some implementations, an RF cable is also provided to connect the test connection port to the signal output port and transmit signals externally.
[0019] In some implementations, the test end of the test version is made of copper alloy.
[0020] Copper alloys are used to ensure conductivity and consistency.
[0021] In some implementations, lifting slots are provided on both opposite sides of the testing machine, and the pressing mechanism is installed in the lifting slots for lifting and lowering.
[0022] By setting lifting slots on opposite sides of the testing machine, the pressing mechanism can press down on the testing machine.
[0023] In some embodiments, the pressing mechanism includes a lifting cylinder and a pressing plate. The lifting cylinder may be fixed in the lifting groove, or the lifting cylinder may be slidably disposed in the lifting groove, and the pressing plate may be disposed at the driving end of the lifting cylinder for lifting and lowering.
[0024] The pressing mechanism is pressed down and raised by a lifting cylinder. The lifting cylinder can be set to be fixed in the lifting groove and raised and lowered by the drive end, or it can be set to be movable in the lifting groove to further increase the lifting range.

[0026] By adding the testing device proposed in the first aspect to the antenna testing equipment, the equipment can test antennas that need to be set perpendicular to the test board.
[0027] The beneficial effects of this utility model of an antenna testing device and antenna testing equipment are:

After pressing down, the first conductive area connects to the testing ends of the testing plate, and the second conductive area connects to the workpiece's power supply point. This allows the vertically positioned testing ends of the testing plate and the power supply end of the workpiece to be electrically connected via the conductive sections. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.
[0042] 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0043] Example 1:
[0044] like Figures 1-3 As shown, this utility model proposes a testing device, comprising:
[0045] The testing machine 1 has a workpiece mounting position 11 for fixing the workpiece 4. The workpiece mounting position 11 has multiple test positions 14. The testing machine 1 has a test plate 3 inside. The test plate 3 is set perpendicular to the workpiece mounting position 11. The test end 31 of the test plate 3 is set above the surface of the workpiece mounting position 11.
[0046] The pressing mechanism 2 presses down on the test platform 1. The pressing mechanism 2 is provided with a conductive part 21. The conductive part 21 is located directly above the test position 14.
[0047] The conductive part 21 is provided with a first conductive area 212 and a second conductive area 213, which are perpendicular to each other. The power supply point of the workpiece 4 is located on the periphery of the test position 14. After being pressed down by the pressing mechanism 2, the first conductive area 212 is connected to the test end 31 of the test plate 3, and the second conductive area 213 is connected to the power supply point of the workpiece 4.
[0048] Specifically, the testing machine 1 is equipped with a workpiece mounting position 11. The shape of the workpiece mounting position 11 can be consistent with the shape of the workpiece 4 to be tested. The workpiece 4 mounting position is equipped with multiple test positions 14, more specifically, generally two. A test plate 3 is set inside the testing machine 1. The test end 31 of the test plate 3 extends from the test position 14 above the surface of the workpiece mounting position 11 for connection with the product's power supply point and to perform electronic product testing. A pressing mechanism 2 is set on the testing machine 1. The pressing mechanism 2 is equipped with a conductive part 21, which is positioned directly above the test position 14. This allows the conductive part 21 to electrically connect the test end 31 extending from the test position 14 to the product's power supply point when the pressing mechanism 2 presses down. The conductive part 21 can be a conductive metal or dielectric material to connect the test end 31 to the power supply point when the pressing mechanism 2 presses down, thus achieving the testing purpose. The pressing mechanism 2 can be a common mechanism that can achieve vertical movement in the direction of the workpiece mounting position 11, such as a cylinder mechanism, a drive motor mechanism, or a guide rail mechanism. The first conductive region 212 and the second conductive region 213 are respectively vertically arranged and connected to the test end 31 and the feed point of the workpiece, achieving a mutually perpendicular arrangement. This allows the device to detect antennas whose feed point and radiation direction are aligned. Furthermore, the use of conductive parts avoids the need for PIN pins.
[0049] The testing device includes a testing platform 1 with a workpiece mounting position 11 for fixing a workpiece 4. The workpiece mounting position 11 has multiple testing positions 14. A testing plate 3 is installed inside the testing platform 1, perpendicular to the workpiece mounting position 11, with its testing end 31 positioned above the surface of the workpiece mounting position 11. A pressing mechanism 2 is also included, pressing down on the testing platform 1. The pressing mechanism 2 has a conductive part 21. The power supply point of the workpiece 4 is located around the testing position 14. After pressing down by the pressing mechanism 2, the conductive part 21 connects the testing end 31 of the testing plate 3 to the power supply point of the workpiece 4. This allows the vertically positioned testing end 31 of the testing plate 3 and the power supply point of the workpiece 4 to be electrically connected via the conductive part 21. This connection method, achieved by pressing down on the conductive part 21, improves the automation and efficiency of the testing process, avoiding inaccurate testing due to improper connection.
[0050] Example 2:
[0051] Please refer to this again. Figures 1-3 ,as well as Figures 4-6 As shown, this embodiment is based on the structure proposed in Embodiment 1, and further describes and optimizes it. The difference is that...
[0052] In some embodiments, the conductive part 21 is conductive foam 211.
[0053] Specifically, the conductive part 21 is conductive foam. The conductive foam 211 is installed on the pressing mechanism 2 to achieve electrical connection between the test terminal 31 of the test board 3 and the test terminal 31 of the electronic product. More specifically, multiple protrusions are provided at the position of the pressing mechanism 2 facing the workpiece mounting position 11. These protrusions may not be conductive, but the conductive part 21 can be located at the end of the protrusions. When the pressing mechanism 2 presses down, the protrusions will make the conductive part 21 contact the test terminal 31 of the test board 3 and the feed terminal of the electronic product in advance for targeted contact. More specifically, in some antenna tests, the conductivity of the conductive part 21 is less than or equal to 0.05 Ω / sq, and the thickness is in the range of 0.5 mm to 2 mm.
[0054] By using conductive foam 211 as a conductive part 21 for conductive connection, damage to the test workpiece 4 and test plate 3 caused by downward pressure stress can be avoided, and the conductive foam 211 can avoid the problem of poor contact.
[0055] In some specific embodiments, the conductive foam 211 has a thickness of 0.5 mm to 2 mm.
[0056] In some specific embodiments, the conductivity of the conductive foam 211 is ≤0.05Ω / sq.
[0057] This ensures that the conductive foam 211 can ensure proper connection between the antenna feed terminal and the test terminal 31 of the test board 3 in some antenna testing environments.
[0058] In some embodiments, a signal output port 32 is provided on one side of the test board 3, and a test connection port 12 is provided on the test machine 1. The signal output port 32 is aligned with the test connection port 12 so that the signal of the test board 3 is transmitted outward.
[0059] Specifically, a signal output port 32 is provided on one side of the test board 3, and a test connection port 12 can be provided on the test machine 1. When the test board 3 is installed on the test machine 1, the signal output port 32 is aligned with the test connection port 12 so that the test signal can be transmitted outward through the test connection port 12.
[0060] By aligning the signal output port 32 and the test connection port 12 on one side of the test board, test signals can be transmitted outward.
[0061] In some embodiments, an RF cable is also provided to connect the test connection port 12 to the signal output port 32 for transmitting signals to the outside.
[0062] Specifically, in some antenna tests, because the antenna has high requirements for signal transmission, an RF cable is provided to connect the test connection port 12 to the signal output port 32 to transmit signals outward.
[0063] By connecting to the outside via an RF cable, signals can be transmitted to the outside, making signal transmission more stable for some electronic products that require stable signal transmission.
[0064] In some alternative embodiments, the test board 3 is equipped with a WIFI module and / or a Bluetooth module to transmit signals wirelessly.
[0065] Specifically, the test version is equipped with a WIFI module and / or a Bluetooth module to avoid the situation where some special electronic products cannot be tested due to structural limitations in setting up test connection port 12, and can transmit data via wireless signals.
[0066] By using a WIFI module and / or a Bluetooth module, wired signal transmission can be avoided, thus preventing some complex test boards 3 and electronic products from being unable to transmit signals through the external signal output port 32 after connection.
[0067] In some specific embodiments, the test terminal 31 of the test version is made of copper alloy.
[0068] Copper alloys are used to ensure conductivity and consistency.
[0069] In some embodiments, the test platform 1 is provided with lifting grooves 13 on both opposite sides, and the pressing mechanism 2 is provided in the lifting grooves 13 for lifting and lowering.
[0070] Specifically, lifting slots 13 are provided on both opposite sides of the test machine 1. The pressing mechanism 2 is installed at both ends in the lifting slots 13 and mounted above the test machine 1 for lifting.
[0071] By setting lifting grooves 13 on opposite sides of the test machine 1, the pressing mechanism 2 can press down on the test machine 1.
[0072] In some alternative embodiments, the pressing mechanism 2 includes a lifting component and a pressing component; the lifting component is disposed in the lifting groove 13, and the pressing component is disposed at the driving end of the lifting component for lifting and lowering.
[0073] Specifically, it includes a lifting assembly and a pressing assembly. The lifting assembly is set in the lifting groove 13. The lifting assembly is set at the driving end of the lifting assembly to lift and lower. By replacing the pressing assembly, the position of the conductive part 21 can be replaced for the power supply end of different electronic products, so that the test machine 1 can test different electronic products.
[0074] The pressing and lifting are achieved by a lifting assembly, and the pressing assembly is set at the drive end of the lifting assembly to achieve the pressing and lifting of the conductive part 21.
[0075] In some embodiments, the pressing mechanism 2 includes a lifting cylinder 22 and a pressing plate 23. The lifting cylinder 22 can be fixed in the lifting groove 13, or the lifting cylinder 22 can be slidably disposed in the lifting groove 13, and the pressing plate 23 is disposed at the driving end of the lifting cylinder 22 for lifting and lowering.
[0076] Specifically, the lifting assembly includes a lifting cylinder 22, which can be fixed in the lifting groove 13 with screws. Only the drive end of the lifting cylinder 22 is used for lifting. Alternatively, a moving guide rail can be provided in the lifting groove 13. The moving guide rail can be equipped with a manually fixed limit part to allow the height of the lifting cylinder 22 to be adjusted, or it can be set to automatically adjust the height with a linear motor so that the overall height of the lifting cylinder 22 can be adjusted within the lifting groove 13. In this way, two lifting height adjustments can be achieved to accommodate more product tests. A pressure plate 23 is set on the drive end to drive the conductive part 21 to lift and connect the test end 31 of the test board 3 and the power supply end of the product.
[0077] The pressing mechanism 2 is pressed down and lifted by the lifting cylinder 22. The lifting cylinder 22 can be fixed in the lifting groove 13 and lifted by the drive end, or it can be set in the lifting groove 13 to further increase the lifting range.
[0078] In other embodiments, the testing machine 1 is provided with a testing base, the workpiece mounting position 11 is provided on the testing base, the testing plate 3 is provided inside the testing base, and the testing base is provided with a metal plate.
[0079] Specifically, the test base can be made of acrylic, while the test frame can be made of black bakelite, and an aluminum metal plate can be installed on the workpiece mounting position 11.
[0080] By setting up a test base, the test machine 1 can be changed according to the product to be tested, thus making the test machine 1 suitable for more test products.
[0081] Example 3:
[0082] like Figure 7 As shown, this embodiment proposes a more specific application of the test device proposed in Embodiments 1 and 2, specifically an antenna test device, including the test device proposed in either Embodiment 1 or Embodiment 2, an antenna control host computer, and a pressure supply device; the antenna control host computer acquires the feedback signal of the test board 3 to determine the data of the antenna under test, and the pressure supply device provides the pressure power source for the pressure-down mechanism 2.
[0083] Specifically, the testing machine 1 is equipped with a testing base. The testing machine 1 and the testing base can be integrated or separate to accommodate different antennas. More specifically, the testing machine 1 and the testing base can be made of acrylic material. The testing machine 1 has a workpiece mounting position 11 for fixing the antenna and two testing positions 14 to match the two feed points of the antenna. Furthermore, a pressing mechanism 2 is mounted on the testing machine 1. The pressing mechanism 2 is positioned on both sides within a lifting groove 13 and moves. The pressing mechanism 2 uses a lifting cylinder 22 to press down the pressing plate 23, which in turn presses down the conductive foam 211 to connect the testing end 31 of the testing board 3 to the feed end of the product. The power source for the lifting cylinder 22 can be provided by a pressure supply device. The system is connected via an RF cable between the signal output port 32 of the testing board 3 and the antenna control host computer to achieve antenna testing feedback.
[0084] By adding the testing device proposed in the first aspect to the antenna testing equipment, the equipment can test antennas that need to be set perpendicular to the test board 3.
[0085] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
