Description

Technical Field

[0001] The invention relates to the technical field of antenna testing, and in particular to an automatic wiring system for antenna testing. Background Art

[0002] Array antenna is an antenna system composed of many identical single antennas (such as symmetrical antennas) arranged in a certain pattern, also known as antenna array. With the advent of the 5G era, array antennas have gradually become popular and widely used to meet the needs of modern communication equipment.

[0003] During the research and development stage of array antennas and before they are put on the market, the performance of array antennas is frequently tested, and wiring work (plugging the test equipment into the array antenna) is a necessary work before testing.

[0004] However, antenna testing efficiency has become a technical bottleneck in corporate R&D work and the 5G era. At the current stage, wiring work is mostly done manually. This traditional wiring method directly leads to extremely low testing efficiency and makes it difficult to achieve large-scale testing of array antennas, so it needs to be improved. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide an automatic wiring system for antenna testing, which solves at least one of the above technical problems to a certain extent and has the advantage of wiring antennas to be tested in large quantities and automatically.

[0006] A first aspect of the present invention provides an automatic wiring system for antenna testing, comprising:

[0007] A conveying device for conveying the antenna to be tested to the test station and outputting the antenna to be tested after the test is completed, wherein the antenna to be tested is provided with a connection portion for wiring test;

[0008] A wiring device corresponding to the test station and connected to an external test device, the wiring device having a plurality of connectors adapted to the connection portion;

[0009] And a driving device drives the wiring device to move toward the antenna to be tested and plugs the connecting part and the connecting piece to achieve the test purpose when the antenna to be tested is in the test station.

[0010] The automatic wiring system for antenna testing that implements the above solution, when wiring work is required, the side of the antenna to be tested with the connection part facing the wiring device, the conveying device transports the antenna to be tested to the test station, and then the wiring device is driven by the driving device, and several connectors on the wiring device move toward the antenna to be tested, so that the connection part and the connector are plugged together and the wiring work is completed. No manual operation is required in this process. Compared with the traditional manual wiring method, it not only improves the wiring efficiency, which is conducive to the realization of large-scale testing of antennas, but also improves the problem of antenna damage caused by the difficulty in controlling the plugging force and accuracy during manual wiring.

[0011] Furthermore, the automatic wiring system further comprises: a rack placed on the ground and comprising a first frame and a second frame;

[0012] The transmission device drives the antenna to be tested to move in a direction parallel to the ground. The transmission device is arranged on the first frame, the driving device is arranged on the second frame, and the wiring device is located between the first frame and the second frame.

[0013] In the automatic wiring system for antenna testing that implements the above scheme, the setting of the rack provides a stable installation platform for the transmission device, the driving device, and the wiring device, thereby improving the stability and accuracy during the wiring work process; at the same time, the wiring device is located inside the rack, so that the rack has a better protection effect on it and saves its occupied space.

[0014] Furthermore, the transmission device comprises:

[0015] A long roller rotatably connected to the first frame at both ends;

[0016] Only the outer end of the short roller is rotatably connected to the first frame to form a first gap between the inner ends of the short roller, and the first gap is used for the connection part and the connection piece to be plugged in;

[0017] A motor is fixedly mounted on the frame, and a transmission structure is provided between the output shaft of the motor and the short roller and the long roller;

[0018] And a laser sensor arranged on the frame for detecting whether the antenna to be tested is transmitted to the test station to control the opening and closing of the motor.

[0019] The automatic wiring system for antenna testing that implements the above scheme can not only achieve the purpose of transmitting the antenna to be tested through the combination of long rollers and short rollers, but also form a first gap at the test station of the first frame, and the first gap is mainly used for the connection between the connecting part and the connecting piece to complete the wiring work; when the motor is working, the output shaft of the motor drives the long roller and the short roller to rotate through the transmission structure, and the purpose of transmitting the antenna to be tested is achieved through friction. When the antenna to be tested is transmitted to the test station, the antenna to be tested will block the induction rays of the laser sensor, cut off the control circuit of the motor, and then the motor stops rotating, so that the antenna to be tested can be accurately stopped at the test station; the setting of the transmission device can realize the full automation of the movement and stopping of the antenna to be tested, which is easy to accurately control, so that the wiring efficiency and wiring accuracy are relatively high.

[0020] Furthermore, the automatic wiring system also includes:

[0021] A tray for supporting the antenna to be tested, having a second notch in the middle adapted to the antenna to be tested and being transported by the transport device, wherein the tray is provided with positioning holes arranged around the antenna to be tested;

[0022] And a positioning device is arranged on the frame and is partially inserted into the positioning hole when the tray is transferred to the testing station.

[0023] The automatic wiring system for antenna testing that implements the above scheme has a connecting part on the antenna to be tested, which is easy to damage the connecting part by directly placing the connecting part on the roller. A tray is placed on the conveying device, and a second notch adapted to the antenna to be tested is provided in the middle of the tray, so that the connecting part of the antenna to be tested is conveniently plugged into the connecting piece, thereby indirectly protecting the connecting part. When the tray is conveyed to the test station, part of the positioning device is inserted into the positioning hole, thereby fixing the tray more stably at the test station, and then in the process of plugging the connecting part and the connecting piece, the tray and the antenna to be tested are more stable.

[0024] Furthermore, the positioning device comprises:

[0025] A mounting base having one end fixedly mounted on the first frame;

[0026] a positioning pin provided at the other end of the mounting seat and inserted into the positioning hole when the tray is transferred to the testing station,

[0027] and a control member disposed between the positioning pin and the mounting seat to ensure that the positioning pin can be inserted and removed, wherein the control member is a spring or an electromagnet;

[0028] When the control member is a spring, the end of the positioning pin extending into the positioning hole is a convex arc-shaped surface, and the convex arc-shaped surface is in direct contact with the opening edge of the positioning hole;

[0029] When the control element is an electromagnet, the electromagnet is controlled to open and close according to the detection result of the laser sensor.

[0030] The automatic wiring system for antenna testing that implements the above scheme, when the control part is a spring, the conveying device drives the tray to move, and then the surface of the tray directly contacts the end of the positioning pin with a convex arc surface, squeezing the positioning pin and compressing the spring. After the positioning hole and the positioning pin are aligned, the elastic restoring force drives the positioning pin to be stuck in the positioning hole. When the tray moves again, the positioning pin is squeezed. Due to the existence of the convex arc surface, the positioning pin has a driving force that drives it to retract, and the spring is compressed again until the positioning pin slides out of the positioning hole; when the control part is an electromagnet, the movement of the positioning pin is controlled by the detection result of the laser sensor. When the motor stops working, the tray just stops at the test station, the magnetic force of the electromagnet disappears, and the positioning pin moves under the action of gravity to achieve the purpose of being stuck in the positioning hole of the tray. When the motor starts working, the electromagnet has magnetic force, thereby attracting the positioning pin to be pulled out of the positioning hole; the above two methods can realize the automatic coordination between the positioning pin and the positioning hole, and the whole process does not require manual operation, and the degree of automation is high.

[0031] Furthermore, the four corners of the tray are chamfered, and the automatic wiring system also includes: a guide block installed on the first frame and used to guide the antenna to be tested into the test station, and the inner side of the guide block is provided with a guide slope.

[0032] In the automatic wiring system for antenna testing that implements the above scheme, before the pallet enters the test station, the position of the pallet may be in a skewed state. Guide blocks are set on both sides of the first frame. Through the guiding effect of the chamfer of the pallet and the guiding inclined surfaces of the guide blocks, the forward direction of the pallet is automatically adjusted during the movement of the pallet, preparing for the next step of precise positioning of the pallet.

[0033] Furthermore, the wiring device also includes:

[0034] A mounting plate for detachably assembling a plurality of the connectors, the mounting plate being arranged in parallel with the antenna to be tested;

[0035] and a connecting assembly arranged between the mounting plate and the driving device.

[0036] In the automatic wiring system for antenna testing that implements the above scheme, the mounting plate is mainly used to fix the connector, which helps to replace the connector that is compatible with different antennas to be tested. At the same time, the mounting plate is arranged in parallel with the antenna to be tested, which is conducive to parallel plugging between multiple connectors and the connecting parts of the antenna to be tested, and the plugging is more stable.

[0037] Furthermore, the connection component includes:

[0038] a chassis directly driven by the drive device;

[0039] A first buffer component is provided between the chassis and the mounting plate and is used for mitigating impact force.

[0040] In the automatic wiring system for antenna testing that implements the above scheme, when the driving device pushes the chassis to move, the chassis pushes the mounting plate to move through the first buffer component to achieve the plug-in connection between the connector and the connecting part. During the wiring process, the chassis and the mounting plate will first compress the first buffer component, which has a buffering effect. Compared with rigid direct plug-in, it is beneficial to extend the service life of the connector and the connecting part.

[0041] Furthermore, the chassis is also provided with a second buffer component which is higher than the plane where the mounting plate is located and is used to mitigate impact force.

[0042] The automatic wiring system for antenna testing that implements the above scheme has a design of a second buffer component. When the driving device pushes the chassis to move, since the plane where the second buffer component is located is higher than the plane where the mounting plate is located, the second buffer component can effectively alleviate a portion of the impact force transmitted to the antenna to be tested, and can also effectively reduce the noise problem caused by rigid contact.

[0043] Furthermore, the driving device is a lifting oil cylinder or a lifting air cylinder.

[0044] The automatic wiring system for antenna testing that implements the above solution, the telescopic part of the lifting cylinder or the lifting cylinder is connected to the wiring device, which can achieve the purpose of driving the wiring device.

[0045] In summary, the embodiments of the present invention have the following beneficial effects:

[0046] First, by adding a transmission device and a driving device, not only the wiring efficiency is improved, which is conducive to large-scale testing of antennas, but also the problem of antenna damage caused by the difficulty in controlling the insertion force and accuracy during manual wiring is improved;

[0047] Secondly, by adding the first buffer component and the second buffer component, the impact force is doubly mitigated, which has a better protective effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Specific embodiment one:

[0056] An automatic wiring system for antenna testing, combined with Figure 1 As shown, it is used for automatically wiring the antenna 11 to be tested, including: a conveying device 2, a wiring device 3, a driving device 4, a frame 5, a tray 6, a positioning device 7 and a guide block 8.

[0057] The conveying device 2 is used to convey the antenna 1 to be tested to the test station and output the antenna 1 after the test. The antenna 1 to be tested is provided with a connection portion 11 (combined with Figure 2 As shown); the wiring device 3 is arranged corresponding to the test station, and the wiring device 3 is located below the test station. The wiring device 3 is externally connected to the test equipment, and the wiring device 3 has a plurality of connectors 31 adapted to the connecting portion 11; when the antenna 1 to be tested is in the test station, the driving device 4 drives the wiring device 3 to move toward the antenna 1 to be tested and plugs the connecting portion 11 and the connector 31 to achieve the test purpose. The driving device 4 is a lifting cylinder, and in other embodiments, it can also be a lifting cylinder. The lifting cylinder or the telescopic part of the lifting cylinder is connected to the wiring device 3, and the purpose of driving the wiring device 3 can be achieved.

[0058] When wiring is required, the side of the antenna 1 to be tested with the connection part 11 is placed toward the wiring device 3, and the conveying device 2 conveys the antenna 1 to be tested to the test station. Then, the wiring device 3 is driven by the driving device 4, and the several connectors 31 on the wiring device 3 move toward the antenna 1 to be tested, so that the connection part 11 and the connector 31 are plugged together and the wiring work is completed. No manual operation is required in this process. Compared with the traditional manual wiring method, it not only improves the wiring efficiency and is conducive to large-scale testing of antennas, but also improves the problem of antenna damage caused by the difficulty in controlling the plugging force and accuracy during manual wiring.

[0059] In this embodiment, only a method of horizontally transmitting the antenna 1 to be tested and vertically driving the wiring device 3 upward is provided to achieve the purpose of automatic wiring. In other embodiments, the antenna 1 to be tested can also be vertically transmitted and the wiring device 3 can be horizontally driven to achieve the purpose of automatic wiring. The vertical transmission method can adopt a lifting structure, and the horizontal driving method can adopt a screw slider structure, which is not limited in this embodiment.

[0060] The rack 5 is specifically composed of aluminum profiles welded or screwed, and is in the shape of a rectangular body. The rack 5 is placed on the ground and includes a first frame 51 and a second frame 52. The first frame 51 and the second frame 52 are both in the shape of a long rectangle. The transmission device 2 drives the antenna 1 to be tested to move in a direction parallel to the ground. The transmission device 2 is arranged on the first frame 51, the driving device 4 is arranged on the second frame 52, and the wiring device 3 is located between the first frame 51 and the second frame 52. The setting of the rack 5 provides a stable installation platform for the transmission device 2, the driving device 4, and the wiring device 3, and improves the stability and accuracy of the wiring work process; at the same time, the wiring device 3 is located inside the rack 5, so that the rack 5 has a better protection effect on it and saves its occupied space.

[0061] The four corners of the tray 6 are all provided with chamfers 62, and the guide block 8 is fixedly installed on the first frame 51 by bolts. The guide block 8 is used to guide the antenna 1 to be tested into the test station, and the inner side of the guide block 8 is provided with a guide slope 81. Before the tray 6 enters the test station, the position of the tray 6 may be in a skewed state. The guide blocks 8 are arranged on both sides of the first frame 51. Through the guiding effect of the chamfer 62 of the tray 6 and the guide slope 81 of the guide block 8, the forward direction of the tray 6 is automatically adjusted during the movement of the tray 6, so as to prepare for the precise positioning of the tray 6 in the next step.

[0062] The wiring device 3 further includes: a mounting plate 32 for detachably assembling a plurality of connectors 31, the mounting plate 32 being arranged in parallel with the antenna 1 to be tested; and a connecting assembly 33 provided between the mounting plate 32 and the driving device 4. The mounting plate 32 is mainly used to fix the connector 31, which helps to replace the connector 31 adapted to different antennas 1 to be tested. Meanwhile, the mounting plate 32 is arranged in parallel with the antenna 1 to be tested, which is conducive to parallel plugging of the plurality of connectors 31 with the connecting portion 11 of the antenna 1 to be tested, and the plugging is more stable.

[0063] The connection assembly 33 includes: a chassis 331 directly driven by the driving device 4; and a first buffer assembly 332 disposed between the chassis 331 and the mounting plate 32 for mitigating impact force. Specifically, there are four groups of the first buffer assembly 332 arranged in a rectangular shape. When the driving device 4 pushes the chassis 331 to move, the chassis 331 pushes the mounting plate 32 to move through the first buffer assembly 332, thereby realizing the connection between the connector 31 and the connecting portion 11. During the wiring process, the chassis 331 and the mounting plate 32 will first compress the first buffer assembly 332, which has a buffering effect. Compared with rigid direct plug-in, it is beneficial to extend the service life of the connector 31 and the connecting portion 11.

[0064] The chassis 331 is also provided with a second buffer assembly 9 which is higher than the plane where the mounting plate 32 is located and is used to mitigate the impact force. Specifically, there are four groups of the second buffer assembly 9 which are arranged in a rectangular shape. The design of the second buffer assembly 9 is such that when the driving device 4 pushes the chassis 331 to move, since the plane where the second buffer assembly 9 is located is higher than the plane where the mounting plate 32 is located, the second buffer assembly 9 can effectively mitigate a part of the impact force transmitted to the antenna 1 to be tested, and can also effectively reduce the noise problem caused by the rigid contact.

[0065] The conveying device 2 includes: a long roller 21 with both ends rotatably connected to the first frame 51; a short roller 22 with only one outer end rotatably connected to the first frame 51 to form a first gap between the inner ends of the short roller 22, and the first gap is used for plugging the connecting part 11 and the connecting piece 31; a motor 23 fixedly mounted on the frame 5, and a transmission structure 24 is provided between the output shaft of the motor 23 and the short roller 22 and the long roller 21; and a laser sensor 25 provided on the frame 5 for detecting whether the antenna 1 to be tested is conveyed to the test station to control the opening and closing of the motor 23. In this embodiment, the transmission structure 24 specifically adopts sprocket transmission. In other embodiments, the transmission structure 24 can also adopt gear transmission or pulley transmission. Through the combination of the long roller 21 and the short roller 22, not only the purpose of transmitting the antenna 1 to be tested can be achieved, but also a first gap is formed at the test station of the first frame 51. The first gap is mainly used for the connection between the connecting part 11 and the connecting piece 31 to complete the wiring work; when the motor 23 is working, the output shaft of the motor 23 drives the long roller 21 and the short roller 22 to rotate through the transmission structure 24, and the purpose of transmitting the antenna 1 to be tested is achieved through friction. When the antenna 1 to be tested is transmitted to the test station, the antenna 1 to be tested will block the induction rays of the laser sensor 25, cut off the control circuit of the motor 23, and then the motor 23 stops rotating, so that the antenna 1 to be tested can be accurately stopped at the test station; the setting of the transmission device 2 can realize the full automation of the movement and stop of the antenna 1 to be tested, which is easy to accurately control, so that the wiring efficiency and wiring accuracy are relatively high.

[0066] Combination Figure 1 and Figure 3 As shown, the tray 6 is used to support the antenna 1 to be tested and has a second notch in the middle thereof adapted to the antenna 1 to be tested. The tray 6 is transported by the conveying device 2. The tray 6 is provided with positioning holes 61 arranged around the antenna 1 to be tested. The positioning device 7 is installed on the frame 5, and when the tray 6 is transported to the test station, part of the positioning device 7 is inserted into the positioning hole 61. Since the antenna 1 to be tested is provided with a connecting portion 11, it is easy to damage the connecting portion 11 by directly placing the connecting portion 11 on the roller. The tray 6 is placed on the conveying device 2, and the second notch in the middle of the tray 6 is adapted to the antenna 1 to be tested, so that the connecting portion 11 of the antenna 1 to be tested can be plugged into the connecting member 31, which indirectly protects the connecting portion 11. When the tray 6 is transported to the test station, part of the positioning device 7 is inserted into the positioning hole 61, so that the tray 6 is relatively stably fixed at the test station, and then in the process of plugging the connecting portion 11 and the connecting member 31, the tray 6 and the antenna 1 to be tested are more stable.

[0067] Combination Figure 4As shown, the first buffer assembly 332 is specifically composed of a first rod 3321 and a first buffer spring 3322. One end of the first rod 3321 is welded to the mounting plate 32. A through hole is provided on the chassis 331 for the other end of the first rod 3321 to slide, and the other end of the first rod 3321 partially extends out of the through hole. The first buffer spring 3322 is located between the mounting plate 32 and the chassis 331. Therefore, during the automatic wiring process, when there is a large impact force, the first buffer spring 3322 will be compressed, and the other end of the first rod 3321 will slide downward along the above-mentioned through hole, thereby playing a buffering and protective role.

[0068] The second buffer assembly 9 is specifically composed of a second rod 91 and a second buffer spring 92. The second buffer spring 92 is sleeved on the second rod 91. A disc is welded at one end of the second rod 91 to limit the second buffer spring 92 from slipping. A through hole is provided on the chassis 331 for the other end of the second rod 91 to slide, and the other end of the second rod 91 partially extends out of the through hole. The second impact spring is located between the first frame 51 and the chassis 331. Therefore, during the automatic wiring process, when there is a large impact force, the second buffer spring 92 first abuts against the second frame 52 and will be compressed, and the other end of the second rod 91 slides downward along the above-mentioned through hole, further playing a buffering and protective role.

[0069] The positioning device 7 includes: a mounting seat 71 with one end fixed on the first frame 51 by multiple sets of bolts; a positioning pin 72 provided at the other end of the mounting seat 71 and inserted into the positioning hole 61 when the tray 6 is transported to the test station; and a control member 73 provided between the positioning pin 72 and the mounting seat 71 to ensure that the positioning pin 72 can be inserted and removed.

[0070] The control member 73 is an electromagnet, which is opened and closed by the detection result of the laser sensor 25. The movement of the positioning pin 72 is controlled by the detection result of the laser sensor 25. When the motor 23 stops working, the tray 6 just stops at the test station, the magnetic force of the electromagnet disappears, and the positioning pin 72 moves under the action of gravity to achieve the purpose of being inserted into the positioning hole 61 of the tray 6. When the motor 23 is turned on, the electromagnet has magnetic force, thereby attracting the positioning pin 72 to be pulled out of the positioning hole 61; the above two methods can realize the automatic matching between the positioning pin 72 and the positioning hole 61, and the whole process does not require manual operation, and the degree of automation is high. Specific embodiment 2:

[0072] An automatic wiring system for antenna testing, which is different from the first embodiment in that it is combined with Figure 5As shown, the control member 73 is a spring, and the end of the positioning pin 72 extending into the positioning hole 61 is a convex arc-shaped surface, and its convex arc-shaped surface is in direct contact with the opening edge of the positioning hole 61. The conveying device 2 drives the tray 6 to move, and then the surface of the tray 6 directly contacts the end of the positioning pin 72 with the convex arc-shaped surface, squeezing the positioning pin 72 and compressing the spring. After the positioning hole 61 and the positioning pin 72 are aligned, the elastic restoring force drives the positioning pin 72 to be stuck in the positioning hole 61. When the tray 6 moves again, the positioning pin 72 is squeezed. Due to the existence of the convex arc-shaped surface, the positioning pin 72 has a driving force to retract, and the spring is compressed again until the positioning pin 72 slides out of the positioning hole 61, so that the automatic matching between the positioning pin 72 and the positioning hole 61 can be realized. The whole process does not require manual operation and has a high degree of automation.

[0073] The first buffer assembly 332 is specifically composed of a third rod 3323 and a third buffer spring 3324. The third buffer spring 3324 is sleeved on the third rod 3323. One end of the third rod 3323 is welded to the chassis 331. A gap is left between the other end of the third rod 3323 and the mounting plate 32. The third buffer spring 3324 is located between the mounting plate 32 and the chassis 331. Therefore, during the automatic wiring process, when there is a large impact force, the third buffer spring 3324 will be compressed, and the gap between the third rod 3323 and the mounting plate 32 will become smaller, thereby playing a buffering and protective role.

[0074] The second buffer assembly 9 is specifically composed of a fourth rod 93 and a fourth buffer spring 94. The fourth buffer spring 94 is sleeved on the fourth rod 93. One end of the fourth rod 93 is welded to the chassis 331. A gap is left between the other end of the fourth rod 93 and the first frame 51. The fourth buffer spring 94 is located between the first frame 51 and the chassis 331. Therefore, during the automatic wiring process, when there is a large impact force, the fourth buffer spring 94 will be compressed, and the gap between the fourth rod 93 and the first frame 51 will become smaller, thereby further playing a buffering and protective role.

[0075] The above implementations do not constitute a limitation on the protection scope of the technical solution. Any modifications, equivalent replacements and improvements made within the spirit and principles of the above implementations should be included in the protection scope of the technical solution.
