Description

Technical Field

[0001] The present application relates to the field of mobile communication technology, and in particular to an automatic testing device. Background Art

[0002] Base station antennas are key components of mobile communication network coverage and are widely used in mobile communication projects. The quality and stability of antennas are directly related to the personal experience of each user. With the gradual promotion and application of 5G antennas, AFU antennas are used more and more. The antenna unit inside the antenna realizes the function of sending and receiving signals. The performance of the antenna unit is related to the overall performance indicators of the antenna and whether it can meet the standards.

[0003] For the welding of more and more antenna units, reflow soldering is gradually adopted, which not only has good welding quality, but also makes it easy to realize automated assembly line operation and improve production efficiency.

[0004] At the same time, in order to ensure that the performance of the antenna unit can meet the index requirements, the welding completed antenna unit needs to be tested for performance indicators. Among them, in the performance indicator test of the antenna unit, the same antenna unit is divided into two parts, the upper module and the lower module, and the oscillator, isolation strips and other components are distributed on the PCB substrates of the upper module and the lower module.

[0037] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "fixed connection" means that the two are connected to each other and the relative position relationship after the connection remains unchanged. In addition, the directional terms mentioned in the embodiments of the present application, such as "inside", "outside", etc., are only references to the directions of the accompanying drawings.

[0042] Base station antennas are key components of mobile communication network coverage and are widely used in mobile communication projects. The quality and stability of antennas are directly related to the personal experience of each user. With the gradual promotion and application of 5G antennas, AFU antennas are used more and more. The antenna unit inside the antenna realizes the function of sending and receiving signals. The performance of the antenna unit is related to the overall performance indicators of the antenna and whether it can meet the standards.

[0043] For the welding of more and more antenna units, reflow soldering is gradually adopted, which not only has good welding quality, but also makes it easy to realize automated assembly line operation and improve production efficiency.

[0044] At the same time, in order to ensure that the performance of the antenna unit can meet the index requirements, the welding completed antenna unit needs to be tested for performance indicators. In the performance indicator test of the antenna unit, the same antenna unit is divided into two parts, the upper module and the lower module. The oscillator, isolation strips and other components are distributed on the PCB substrates of the upper module and the lower module.

[0045] In the related art, the PCB substrate is pressed from the top by means of a magnetic pressure plate, a screw-tightening pressure plate, etc. However, since the PCB substrate is made of glass fiber material and is relatively thin, has a large area, is relatively soft and lacks rigidity, and has an uneven surface, the PCB substrate will be forced upward under the elastic force of the contact of the test connector. Even under the pressure of the pressure plate, it cannot be guaranteed that each test connector can have good contact with the PCB substrate, which affects the test results of the antenna unit and cannot accurately test the performance indicators of the antenna unit. In addition, the pressure plate needs to be placed manually or tightened with screws, which reduces the efficiency of the test.

[0046] In order to solve the above technical problems, the present application provides an automatic testing device.

[0047] See also Figure 1-Figure 3 , Figure 1 A schematic diagram of an automatic testing device provided in some embodiments of the present application, Figure 2 A partial schematic diagram of an automatic testing device provided in some embodiments of the present application, Figure 3 Schematic diagram of a test connector provided in some embodiments of the present application. The automatic test device 100 is used to test the antenna unit 1. The automatic test device 100 may include a positioning base plate 2, a test connector 3, a test cable 5 and a plurality of elastic tension adsorption heads 4.

[0048] The antenna unit 1 is located on one side of the positioning base plate 2. For example, in the height direction of the automatic testing device 100, the antenna unit 1 may be located above the positioning base plate 2.

[0049] The shape of the positioning base plate 2 is the same as that of the antenna unit 1. For example, if the antenna unit 1 is a rectangular parallelepiped, the positioning base plate 2 is also a rectangular parallelepiped, thereby avoiding affecting the performance index test of the antenna unit 1.

[0050] The test connector 3 is disposed on the positioning base plate 2 and is used to connect to the test port 13 of the antenna unit 1. Specifically, in the height direction of the automatic test device 100, the orthographic projection of the test connector 3 on the plane where the antenna unit 1 is located overlaps with the test port 13.

[0051] There may be more than one test connector 3 and more than one test port 13 , and one test connector 3 corresponds to one test port 13 .

[0052] For example, the test connector 3 may have a contact 31, and the contact 31 may be elastically movable up and down. When the test connector 3 is fixed on the positioning base plate 2, the contact 31 of the test connector 3 may be higher than the surface of the positioning base plate 2 facing the antenna unit 1. Thus, it can be ensured that the test connector 3 is in good contact with the test port 13.

[0053] The elastic up and down movement of the contact 31 can be achieved by elastic members such as springs.

[0054] A plurality of elastic tension adsorption heads 4 can be arranged on the positioning base plate 2. Herein, "plurality" means that the number of the elastic tension adsorption heads 4 is two or more. A plurality of elastic tension adsorption heads 4 can be arranged on the positioning base plate 2 at intervals.

[0055] For example, the elastic tension absorption head 4 can be made of elastic material so that the elastic tension absorption head 4 can be flexible.

[0056] The elastic tension adsorption head 4 is connected to a vacuum generator (not shown), and a plurality of elastic tension adsorption heads 4 are used to adsorb the antenna unit 1. Therefore, when the antenna unit 1 needs to be tested, the compressed air generates negative pressure through the vacuum generator, so that the plurality of elastic tension adsorption heads 4 adsorb the antenna unit 1, and the control method is simple. In addition, the antenna unit 1 can be subjected to a uniform adsorption force, which can reduce the impact on the test result of the antenna unit 1.

[0057] The elastic tension adsorption head 4 can have a test state. In the test state, the test connector 3 is connected to the test port 13, the elastic tension adsorption head 4 is connected to the antenna unit 1, and the antenna unit 1 is driven to move in the direction close to the positioning base plate 2. Specifically, in the test state, the antenna unit 1 is placed on the upper surface of the positioning base plate 2, and the compressed air generates a negative pressure through the vacuum generator. A plurality of elastic tension adsorption heads 4 adsorb most of the lower surface of the antenna unit 1. Under the action of the negative pressure, the height of the elastic tension adsorption head 4 becomes smaller. Since the elastic tension adsorption head 4 is fixed on the positioning base plate 2, the elastic tension adsorption head 4 will generate a downward pulling force, so that the antenna unit 1 moves in the direction close to the positioning base plate 2, so that the antenna unit 1 can be flat on the upper surface of the positioning base plate 2, so that each test connector 3 can be in good contact with the test port 13, and then the performance indicators of the antenna unit 1 can be accurately tested.

[0058] Exemplarily, a placement position 25 for facilitating placement of the antenna unit 1 may be provided on the positioning base plate 2 .

[0059] The test connector 6 is connected to the test connector 3 via the test cable 5 . The test connector 6 is used to connect to a test instrument, so that the performance test of the antenna unit 1 can be performed.

[0060] According to the automatic testing device 100 of the embodiment of the present application, by setting a plurality of elastic tension adsorption heads 4 on the positioning base plate 2, the elastic tension adsorption heads 4 are used to adsorb the antenna unit 1, and when the elastic tension adsorption heads 4 are in the testing state, the elastic tension adsorption heads 4 are connected to the antenna unit 1, and drive the antenna unit 1 to move in the direction close to the positioning base plate 2, so that the antenna unit 1 can be flat on the upper surface of the positioning base plate 2, so that the force on the antenna unit 1 can be uniform, and each test connector 3 can be in good contact with the test port 13, so that the performance index of the antenna unit 1 can be accurately tested. In addition, there is no extra object on the upper part of the PCB substrate 14 of the antenna unit 1, which is conducive to improving the accuracy of the antenna performance index test, thereby improving the test quality and reducing production costs.

[0061] See also Figure 1 , Figure 2 and Figure 4 , Figure 4 Schematic diagram of an elastic tension adsorption head provided for some embodiments of the present application. In some embodiments, the elastic tension adsorption head 4 may include an adsorption head upper portion 41 and an adsorption head middle portion 42. One end of the adsorption head upper portion 41 is used to adsorb the antenna unit 1, and the other end is connected to the adsorption head middle portion 42. Exemplarily, the adsorption head upper portion 41 can be formed in a trumpet shape, and the middle area between the adsorption head middle portion 42 and the adsorption head upper portion 41 is hollow, which can be used for ventilation. Among them, the trumpet-shaped adsorption head upper portion 41 can improve the reliability of the connection with the antenna unit 1.

[0062] In the height direction of the elastic pulling force adsorption head 4, the cross-sectional area of ​​the middle part 42 of the adsorption head increases first and then decreases. This arrangement facilitates the deformation of the middle part 42 of the adsorption head.

[0063] The cross-sectional area of ​​the middle part 42 of the adsorption head refers to the area of ​​the cross section of the middle part 42 of the adsorption head on the horizontal plane. In the height direction of the elastic tension adsorption head 4, the increase or decrease of the cross-sectional area of ​​the middle part 42 of the adsorption head can be linear, and the increase or decrease of the cross-sectional area of ​​the middle part 42 of the adsorption head can be non-linear, and the present application does not limit this.

[0064] In the test state, the height of the middle part 42 of the adsorption head is reduced to drive the antenna unit 1 to move in the direction close to the positioning base plate 2. Specifically, the middle part 42 of the adsorption head is a flexible part. When the elastic tension adsorption head 4 is in the test state, the middle part 42 of the adsorption head can be deformed, and the height of the middle part 42 of the adsorption head is reduced, driving the antenna unit 1 to move in the direction close to the positioning base plate 2. Such a simple structure is provided, which is conducive to reducing the manufacturing cost of the automatic testing device 100.

[0065] Please continue reading Figure 1 , Figure 2 and Figure 4 In some embodiments, the automatic testing device 100 may further include an adsorption head fixing plate 44 and an adsorption head fixing member 43. The adsorption head fixing plate 44 is disposed on a side of the positioning base plate 2 away from the antenna unit 1. The adsorption head fixing plate 44 and the positioning base plate 2 may be detachably connected. For example, the adsorption head fixing plate 44 and the positioning base plate 2 may be detachably connected by screws.

[0066] A plurality of suction head avoidance positions 21 may be provided on the positioning base plate 2, and the elastic tension suction head 4 is provided through the suction avoidance positions, so that part of the elastic tension suction head 4 protrudes out of the positioning base plate 2. Among them, the suction head avoidance position 21 may be a stepped hole, so when the suction head middle portion 42 is deformed, the suction head middle portion 42 abuts against the inner wall of the suction head avoidance position 21, thereby limiting the deformation of the elastic tension suction head 4, and further limiting the movement stroke of the antenna unit 1, which is beneficial to improving the safety and reliability of the automatic testing device 100, and also can avoid interference when the elastic tension suction head 4 is deformed. The suction head avoidance position 21 may also be a straight hole, which can also avoid interference when the elastic tension suction head 4 is deformed.

[0067] The elastic tension adsorption head 4 is detachably connected to the adsorption head fixing plate 44 through the adsorption head fixing member 43. For example, the adsorption head fixing member 43 and the adsorption head fixing plate 44 can be detachably connected by means of snap connection, fastener connection, magnetic attraction, etc.

[0068] Therefore, it is convenient to replace and repair the elastic tension adsorption head 4 , which is beneficial to improving the maintainability of the automatic testing device 100 .

[0069] Exemplarily, the elastic tension adsorption head 4 and the adsorption head fixing part 43 can be an integrally formed part, and such a configuration is conducive to improving the assembly efficiency of the automatic testing device 100 .

[0070] Please continue reading Figure 1 , Figure 2 and Figure 4 In some embodiments, the automatic testing device 100 may further include an air pipe joint 45. The air pipe joint 45 is connected to the adsorption head fixing plate 44. The air pipe joint 45 and the adsorption head fixing plate 44 may be fixedly connected or detachably connected, which is not limited in the present application.

[0071] The suction head fixing part 43 may have a ventilation cavity. One end of the trachea connector 45 is connected to the ventilation cavity, and the other end is connected to the vacuum generator. In this way, the suction head fixing part 43 can be prevented from affecting the connection between the elastic tension suction head 4 and the vacuum generator, and the connection of the vacuum generator is also facilitated, thereby reducing the difficulty of assembly.

[0072] Exemplarily, the outer side of the adsorption head fixing part 43 may have threads, and the adsorption head fixing part 43 and the adsorption head fixing plate 44 may be connected by threads.

[0073] It should be noted that the trachea connector 45 may also be directly connected to the elastic tension adsorption head 4, for example, a mounting hole connected to the trachea connector 45 is provided on the side wall of the elastic tension adsorption head 4. This application does not impose any limitation on this.

[0074] Please continue reading Figure 1-Figure 5 , Figure 5 Schematic diagram of antenna unit provided for some embodiments of the present application. In some embodiments, the antenna unit 1 may include an upper module 11 and a lower module 12. Components such as a vibrator 15 and an isolation strip 16 are distributed on the PCB substrate 14 of the upper module 11 and the lower module 12. The upper module 11 and the lower module 12 may be spaced apart on one side of the positioning base plate 2.

[0075] The automatic testing device 100 may also include a first controller and a second controller. The first controller may be used to control the movement of the elastic tension adsorption head 4 connected to the upper module 11, and the second controller is used to control the movement of the elastic tension adsorption head 4 connected to the lower module 12. Specifically, part of the plurality of elastic tension adsorption heads 4 is connected to the upper module 11, and the rest is connected to the lower module 12. The first controller is used to control the elastic tension adsorption head 4 connected to the upper module 11 to control whether the elastic tension adsorption head 4 drives the upper module 11 to move in a direction close to the positioning base plate 2. The second controller is used to control the elastic tension adsorption head 4 connected to the lower module 12 to control whether the elastic tension adsorption head 4 drives the lower module 12 to move in a direction close to the positioning base plate 2.

[0076] Exemplarily, the elastic tension adsorption head 4 connected to the upper module 11 is connected to the vacuum generator through the air pipe joint 45, and then connected to the first hand valve, the first hand valve is connected to the first solenoid valve, and the first solenoid valve is controlled by the first controller. The elastic tension adsorption head 4 connected to the lower module 12 is connected to the vacuum generator through the air pipe joint 45, and then connected to the second hand valve, the second hand valve is connected to the second solenoid valve, and the second solenoid valve is controlled by the second controller. At the same time, the hand valve can also be used to control a single elastic tension adsorption head 4.

[0077] Thus, the performance test of the antenna unit 1 can be realized by automatic control, which is beneficial to improve labor efficiency and reduce the labor intensity of the operator. At the same time, the first controller and the second controller can synchronize the overall test or the sub-module test of the multiple test ports 13 of the upper module 11 and the lower module 12, which is beneficial to improve the flexibility of the antenna unit 1 test.

[0078] Please continue reading Figure 1 and Figure 2 In some embodiments, the automatic testing device 100 may further include a soundproof cover 7 and sound-absorbing cotton. The soundproof cover 7 may be located on a side of the positioning base plate 2 away from the antenna unit 1 and may be detachably connected to the positioning base plate 2. The soundproof cover 7 may be detachably connected to the positioning base plate 2 by means of fasteners, snap-on connection, etc.

[0079] The soundproof cover 7 may have a vent hole and a through hole, and the air pipe joint 45 is provided with the through hole and connected to the vacuum generator. Specifically, one end of the air pipe joint 45 passes through the through hole and is connected to one end of the vacuum generator, and the other end of the vacuum generator is connected to the hand valve, and the hand valve is connected to the solenoid valve. This arrangement facilitates the installation of the air pipe joint 45, thereby helping to reduce the difficulty of assembling the automatic testing device 100.

[0080] The sound-absorbing cotton and the vacuum generator are both located in the soundproof cover 7. Thus, it can be used to reduce or eliminate the noise generated by the vacuum generator, thereby helping to improve the user experience.

[0081] Please continue reading Figure 1 and Figure 2 In some embodiments, the automatic test device 100 may further include a positioning round pin 22 and a positioning flat pin 23. The positioning base plate 2 may be provided with a first positioning hole 26 and a second positioning hole 27. The antenna unit 1 may have a third positioning hole 17 and a fourth positioning hole 18. The positioning round pin 22 penetrates the first positioning hole 26 and the third positioning hole 17, and the positioning flat pin 23 penetrates the second positioning hole 27 and the fourth positioning hole 18. Specifically, the first positioning hole 26 corresponds to the third positioning hole 17, and the shapes of the first positioning hole 26 and the third positioning hole 17 may be the same, such as circular, elliptical, etc. The positioning round pin 22 may penetrate the first positioning hole 26 and the third positioning hole 17, and be connected to the positioning base plate 2. The second positioning hole 27 corresponds to the fourth positioning hole 18, and the shapes of the second positioning hole 27 and the fourth positioning hole 18 may be the same, but different from the shapes of the first positioning hole 26 and the third positioning hole 17, and the positioning flat pin 23 may penetrate the second positioning hole 27 and the fourth positioning hole 18, and be connected to the positioning base plate 2.

[0082] Exemplarily, the upper module 11 is provided with a third positioning hole 17 and a fourth positioning hole 18, the positioning round pin 22 penetrates the first positioning hole 26 and the third positioning hole 17, and the positioning flat pin 23 penetrates the second positioning hole 27 and the fourth positioning hole 18, so as to complete the installation and positioning of the upper module 11. The lower module 12 is also provided with a third positioning hole 17 and a fourth positioning hole 18, and the positioning method of the lower module 12 is the same as that of the upper module 11, which will not be repeated here.

[0083] In this way, the antenna unit 1 can be accurately positioned and fool-proofed, which is beneficial to improving the testing efficiency of the automatic testing device 100 .

[0084] Please continue reading Figure 1 and Figure 2 In some embodiments, the surface of the positioning base plate 2 facing the antenna unit 1 may be provided with a connector positioning hole 24. The test connector 3 is provided with the connector positioning hole 24 and is detachably connected to the positioning base plate 2. Thus, the installation of the test connector 3 can be pre-positioned through the connector positioning hole 24, thereby reducing the difficulty of installing the test connector 3. At the same time, the detachable connection method facilitates the replacement and maintenance of the test connector 3, thereby helping to reduce the use cost of the automatic test device 100.
