DETAILED DESCRIPTION

[0037] In order to make the purpose, technical scheme and advantages of one or more embodiments of the present specification more clear, the technical scheme of one or more embodiments of the present specification will be described clearly and completely below in combination with the specific embodiments of the present specification and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present specification, not all the embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of one or more embodiments of the present specification.

[0038] Please refer to Figure 1The application provides a radar performance detection device, which can comprise a detection device shell 8, a plurality of performance detectors 3, a leakage detector 1 and a controller 7.

[0039] The leakage detector 1 is arranged in the detection device shell 8 and has an air inlet port and a plurality of air outlet ports, the air inlet port of the leakage detector 1 can be connected with an air source, each air outlet port can be detachably connected with one performance detector 3, different types of performance detectors 3 need to be matched with different types of radar equipment, and different types of performance detectors 3 can be detachably connected with the air outlet ports of the leakage detector 1. The leakage detector 1 can deliver the gas obtained from the air source to the performance detectors 3, each performance detector 3 can detect the air tightness of one radar equipment, the plurality of performance detectors 3 can simultaneously detect a plurality of radar equipment, and the air tightness of different types of radar equipment can be detected by replacing different types of performance detectors 3 connected with the air outlet ports of the leakage detector 1.

[0040] When the leakage detector 1 delivers the gas to the performance detectors 3 through the air outlet ports, the leakage detector 1 can send the amount of gas in the performance detectors 3 to the controller 7 in real time through a signal output port, and the leakage detector 1 stops delivering the gas to the performance detectors 3 when the controller 7 detects that the amount of gas in the performance detectors 3 reaches a preset value. The performance detectors 3 start to detect the air tightness of the radar equipment by means of pressure maintenance, after a period of time, the leakage detector 1 measures the air pressure value of the gas in the performance detectors 3 and sends the air pressure measurement value to the controller 7, the controller 7 generates an air tightness detection result of the detected radar equipment according to the received air pressure measurement value, if the air pressure measurement value is within a preset value range, the air tightness detection result of the detected radar equipment is qualified, and if the air pressure measurement value is not within the preset value range, the air tightness detection result of the detected radar equipment is unqualified.

[0041] It should be noted that the types or models of the radar equipment to be detected can be various, such as millimeter wave radar, microwave radar, over-the-horizon radar, laser radar and the like, and the application does not make a specific limitation.

[0042] The radar performance detection device can simultaneously detect the air tightness of a plurality of radar equipment, and when different types of radar equipment are detected, only the performance detectors 3 in the radar performance detection device need to be replaced, without the need of replacing the whole radar performance detection device, so that the working efficiency of the radar performance detection device and the applicability of detecting different types of radar equipment can be improved.

[0043] Please refer to Figure 2In a specific embodiment of the present application, the performance detector can include a detector housing 10, a power telescopic rod 11, a pressing plate 12, and a closed sealing strip 18.

[0044] An upper surface of a bottom surface of the detector housing 10 is provided with a boss 17, which is a hollow structure communicating a top surface of the boss 17 and an inner bottom surface of the detector housing 10. A radar device is placed in the hollow area of the boss 17, and the height of the radar device is higher than the height of the boss 17, so that the lower part of the radar device is located in the hollow area, and the upper part of the radar device protrudes out of the boss 17. In addition, the top surface of the boss 17 is further provided with the closed sealing strip 18, which is placed around the upper end of the boss 17. The pressing plate 12 is connected with the power telescopic rod 11, the power telescopic rod 11 is arranged in the detector housing 10 and opposite to the boss 17, and the power telescopic rod 11 can drive the pressing plate 12 to approach or move away from the boss 17. When the power telescopic rod 11 is elongated, the power telescopic rod 11 can drive the pressing plate 12 to approach the boss 17 and press the closed sealing strip 18 tightly on the top surface of the boss 17. At this time, the pressing plate 12, the closed sealing strip 18, the hollow structure of the boss 17, and the bottom surface of the detector housing 10 form a sealed space.

[0045] In actual application, the hollow structure can be a circular hollow structure or a square hollow structure, as long as it can accommodate the lower part of the radar device and cooperate with the pressing plate 12 to form a sealed space, and the present application does not make specific limitation thereon.

[0046] In actual application, the shape of the closed sealing strip 18 can be a circular structure or a square structure, as long as the closed sealing strip 18 can be placed on the top surface of the boss 17 around the hollow structure of the boss 17, and the pressing plate 12 can press the closed sealing strip 18 tightly, and the present application does not make specific limitation thereon.

[0047] In actual application, the power telescopic rod 11 can be a pneumatic cylinder, an electric push rod, or a hydraulic cylinder, as long as it can drive the pressing plate 12 to approach and press the closed sealing strip 18 tightly on the top surface of the boss 17 or move away from the closed sealing strip 18, and the present application does not make specific limitation thereon.

[0048] In actual application, since the closed sealing strip 18 is extruded by the pressing plate 12, the gap between the pressing plate 12 and the top surface of the boss 17 is completely sealed, so that the sealed space formed by the pressing plate 12, the closed sealing strip 18, the hollow structure of the boss 17, and the inner bottom surface of the detector housing 10 has high sealing performance, thereby providing a strict sealed space for the air tightness detection, and significantly improving the accuracy of the air tightness detection of the radar device.

[0049] In a specific embodiment of the present application, the leak detector 1 can have multiple first gas supply ports, which can be used to supply the gas obtained from the gas source to the performance detector 3, and each first gas supply port can be provided with a first interface. The detector housing 10 of the performance detector 3 can be provided with a second interface 16, which can be arranged on the bottom surface of the detector housing 10, or on the side surface or top surface of the detector housing 10, but needs to be connected to the sealed space in the performance detector 3. The second interface 16 can be directly connected to the sealed space, or can be connected to the sealed space through a gas pipeline. In this way, the gas in the leak detector 1 can be supplied to the second interface 16 at the detector housing 10 through the first interface of the first gas supply port, and then supplied to the sealed space of the performance detector 3 through the second interface 16, so as to perform the air tightness detection on the radar device placed in the performance detector 3.

[0050] The first interface and the second interface 16 can be detachably connected, and the specific connection mode of the first interface and the second interface 16 can be VCR connection, flange connection, or screw connection, etc. The present application does not make specific limitations on this.

[0051] In actual application, the first interface arranged at any one of the first gas supply ports of the leak detector 1 and the second interface 16 arranged at the detector housing 10 can be detachably connected. In this way, different models of performance detectors 3 can be replaced, so that the radar performance detection device only needs to replace the performance detector 3, and does not need to replace other components such as the leak detector 1 and the controller 7, so as to realize the air tightness detection on different types of radar devices, and improve the wide applicability of the radar performance detection device and the convenience of detecting the air tightness of different radar devices.

[0052] In a specific embodiment of the present application, the radar performance detection device can perform electrical performance detection on the radar device while performing air tightness detection on the radar device. Therefore, the performance detector 3 can further include a probe 13 and an electrical performance detection module 14. The probe 13 is arranged on the inner bottom surface of the detector housing 10 and located in the hollow area of the boss 17, and the electrical performance detection module 14 is arranged in the detector housing 10. One end of the probe 13 is communicatively connected to the electrical performance detection module 14. When the power extension rod 11 drives the pressing plate 12 to press the radar device, the pin of the radar device can effectively contact the other end of the probe 13, so as to realize the power supply of the radar device by the electrical performance detection module 14. After the radar device is powered on, the electrical performance signal of the radar device can be fed back to the electrical performance detection module 14 through the effective contact between the pin and the probe 13. The electrical performance signal fed back by the radar device to the electrical performance detection module 14 can be a current signal, a voltage signal, or a resistance signal, etc.

[0053] The electrical performance detection module 14 can also be in communication connection with the controller 7 to send the electrical performance signal value measured by the detected radar equipment to the controller 7, and the controller 7 generates an electrical performance detection result for the detected radar equipment according to the received electrical performance signal value. If the electrical performance signal value is within the preset value range, the electrical performance detection result generated for the detected radar equipment is qualified. If the electrical performance signal value is not within the preset value range, the electrical performance detection result generated for the detected radar equipment is unqualified.

[0054] In actual application, the performance detector 3 can also perform electrical performance detection on the radar equipment while performing air tightness detection on the radar equipment, so as to avoid performing electrical performance detection on the radar equipment after the air tightness detection is completed, thereby reducing the detection time of the radar equipment and accelerating the production rhythm of the radar equipment.

[0055] In an embodiment of the present application, a plurality of installation grooves 2 can be arranged at the detection device housing 8. The shapes of the installation grooves 2 can be the same, and the number of the installation grooves 2 can be reasonably arranged according to the size of the radar performance detection device, which is not limited in the present application. Each installation groove 2 is used to place one performance detector 3. The internal structure of each installation groove 2 can be adapted to the external shape of the detector housing 10 of the performance detector 3 of different models, i.e., the external shapes of the detector housings 10 of the performance detectors 3 of different models are consistent, so that the detector housings 10 of the performance detectors 3 of different models can be placed in the same installation groove 2, so as to realize that the radar performance detection device can replace the performance detectors 3 of different models, thereby performing air tightness detection on radar equipment of different models.

[0056] In actual application, each installation groove 2 arranged at the detection device housing 8 can place one performance detector 3, and each performance detector 3 can perform air tightness detection on one radar equipment. Therefore, the radar performance detection device can realize batch detection on radar equipment. When batch detection is performed, all installation grooves 2 can place the same type of performance detector 3 to perform batch detection on the same type of radar equipment. Some installation grooves 2 can place the performance detector 3 of the first type, and other installation grooves 2 can place the performance detector 3 of the second type or other types to perform batch detection on radar equipment of different models. Such arrangement can improve the working efficiency of the radar performance detection device in batch detection of radar equipment and accelerate the production rhythm of radar equipment.

[0057] In a specific embodiment of the present application, the detector housing 10 is provided with a third interface 15, which can be arranged at the bottom of the outer surface of the detector housing 10. A fourth interface is arranged in the mounting groove 2, which can be arranged at the inner bottom surface of the mounting groove 2. The third interface 15 and the fourth interface can be detachably connected. When the performance detector 3 is placed in the mounting groove 2, the third interface 15 and the fourth interface are electrically connected. The third interface 15 can obtain power from the radar performance detection device and transmit the power to the electrical performance detection module 14 of the performance detector 3. The electrical performance detection module 14 uses the obtained power to complete the electrical performance detection of the radar device.

[0058] It should be noted that when the electrical performance detection module 14 completes the electrical performance detection of the radar device and sends the detected electrical performance signal value to the controller 7, the communication connection between the electrical performance detection module 14 and the controller 7 can be realized by using the third interface 15 and the fourth interface, or by other means, such as establishing a new communication line between the electrical performance detection module 14 and the controller 7 to realize the communication connection between them. The present application does not make specific limitations in this regard.

[0059] In actual application, the third interface 15 arranged on the detector housing 10 and the fourth interface arranged in the mounting groove 2 can be detachably connected. In this way, different models of performance detectors 3 can be replaced, so that the radar performance detection device only needs to replace the performance detector 3, without replacing other components such as the detection device housing 8 and the controller 7, to realize the electrical performance detection of different types of radar devices, thereby improving the wide applicability of the radar performance detection device and the convenience of detecting the electrical performance of different radar devices.

[0060] In a specific embodiment of the present application, the inner bottom surface of the detector housing 10 is provided with a first recess, which is located in the hollow area of the boss 17, and the shape and structure of the first recess are adapted to the shape of the lower part of the radar device. The probe 13 connected to the pin needle of the radar device is arranged in the first recess. The lower bottom surface of the pressing plate 12 is provided with a second recess, which is located in the area corresponding to the hollow area of the boss 17, and the shape and structure of the second recess are adapted to the shape of the upper part of the radar device to be detected. When the power telescopic rod 11 drives the pressing plate 12 to move close to the boss 17 and tightens the closed sealing strip 18 on the top surface of the boss 17, the first recess contacts the lower part of the radar device, and the second recess contacts the upper part of the radar, so as to fix the radar device in the cavity formed by the first recess and the second recess, so that the pin needle of the radar device can effectively contact the probe 13, and the electrical performance detection of the radar device is realized.

[0061] In a specific embodiment of the present application, in order to avoid damaging the radar device due to excessive extrusion force when the pressing plate 12 presses the radar device in the cavity formed by the first groove and the second groove, an inner liner can be arranged in the first groove and the second groove. The inner liner can be a mesh elastic inner liner, and the material of the inner liner can be rubber. When the radar device is fixed in the cavity formed by the first groove and the second groove, the mesh elastic inner liner arranged in the first groove and the second groove can be in contact with the radar device. The mesh elastic inner liner can play a buffering role when the pressing plate 12 extrudes the radar device, so that the radar device can be fixed at the first groove and damage to the radar device can be avoided.

[0062] In a specific embodiment of the present application, after the radar performance detection device completes detection on the radar device, the detection result also needs to be displayed to the operator. Therefore, in order to facilitate the display of the detection result of the radar device to the operator, the radar performance detection device can further include a display device 6. The display device 6 can be arranged on the radar performance detection device or can be separately arranged in other areas. The signal output port of the controller 7 is connected to the signal input port of the display device 6, so that the air tightness detection result and the electrical performance detection result of the radar device can be displayed on the display device 6, so that the operator can know whether the performance of the radar device is qualified. The communication mode between the display device 6 and the controller 7 can be through wired transmission or wireless transmission, which is not limited in the present application.

[0063] In a specific embodiment of the present application, the amount of gas delivered by the leakage detector 1 to the sealed space needs to be strictly controlled. When the amount of gas in the sealed space reaches the preset value and the pressure maintaining test on the radar device is performed, the leakage detector 1 should stop delivering gas to the sealed space. Therefore, the radar performance detection device can further include an electromagnetic valve 9 arranged between the external gas source and the leakage detector 1. That is, the second gas inlet port of the electromagnetic valve 9 is connected to the external gas source, and the second gas outlet port of the electromagnetic valve 9 is connected to the first gas inlet port of the leakage detector 1. The electromagnetic valve 9 is used to control the on and off of the delivered gas. When the electromagnetic valve 9 is opened, the leakage detector 1 can deliver gas to the sealed space. When the amount of gas in the sealed space reaches the preset value, the electromagnetic valve 9 is closed, and the leakage detector 1 stops delivering gas to the sealed space.

[0064] It should be noted that the signal input port of the electromagnetic valve 9 can be connected with the signal output port of the controller 7, so that the controller 7 can control the opening or closing of the valve body of the electromagnetic valve 9. When the controller 7 sends the valve body opening instruction to the electromagnetic valve 9, the electromagnetic valve 9 opens the valve body, the leak detector 1 starts to supply gas to the sealed space, and at the same time the leak detector 1 sends the real-time gas amount in the sealed space to the controller 7. When the gas amount value in the sealed space received by the controller 7 reaches the preset value, the controller 7 sends the valve body closing instruction to the electromagnetic valve 9, the electromagnetic valve 9 closes the valve body, and the leak detector 1 stops supplying gas to the sealed space.

[0065] In an embodiment of the present application, after the radar performance detection device detects the radar equipment, in order to quickly distinguish qualified products and unqualified products, the radar equipment needs to be bound with the performance detector 3 before being placed in the performance detector 3. Therefore, the radar performance detection device can further include a code scanner 5. The code scanner 5 can be arranged on the radar performance detection device, or can be separately arranged in other areas. The signal output port of the code scanner 5 is connected with the signal input port of the controller 7. The code scanner 5 scans the two-dimensional code of the radar equipment and the two-dimensional code of the performance detector 3 respectively, so as to bind the scanned radar equipment and the performance detector 3. After detection is completed, the controller 7 can divide the performance detector 3 into four categories: the radar equipment in the performance detector is qualified in both gas tightness and electrical performance, the radar equipment in the performance detector is unqualified in gas tightness, the radar equipment in the performance detector is unqualified in electrical performance, and the radar equipment in the performance detector is unqualified in both gas tightness and electrical performance. Then, according to the binding result of the radar equipment and the performance detector 3, the radar equipment can be divided into four types: the radar equipment qualified in both gas tightness and electrical performance, the radar equipment unqualified in gas tightness, the radar equipment unqualified in electrical performance, and the radar equipment unqualified in both gas tightness and electrical performance.

[0066] In an embodiment of the present application, the performance detector further includes a light barrier sensor 19. The light barrier sensor 19 can be arranged on the top wall of the inner surface of the detector shell, or can be arranged on the side wall of the inner surface of the detector shell. The signal output port of the light barrier sensor 19 can be connected with the signal input port of the controller 7 through the third interface 15 on the detector shell 10 and the fourth interface in the mounting groove 2. The light barrier sensor 19 is used to detect the placement position of the radar equipment in the detector shell 10. When the mechanical hand enters the detector shell 10 to grab the radar equipment, and slowly moves and places the radar equipment in the appropriate position in the first groove, the light barrier sensor 19 sends a signal to the controller 7 that the radar equipment is placed in position. Then the controller 7 sends an instruction to the mechanical hand to release the grabbing action of the radar equipment.

[0067] It should be noted that the signal output port of the reflection sensor 19 can also be connected to the signal input port of the controller 7 in other ways, such as: a new communication line is built between the reflection sensor 19 and the controller 7 to realize the communication connection between them. The present application does not make specific limitations on this.

[0068] In a specific embodiment of the present application, the leakage detector 1, the plurality of performance detectors 3, the code scanner 5, the reflection sensor 19 and other components in the radar performance detection device need to communicate with the controller 7. If each component is individually connected to the controller 7, the controller 7 needs to be configured with multiple communication ports. In order to reduce the occupation of the communication ports of the controller 7, the radar performance detection device can further include a distributed IO module 4, which has the function of converging multiple communication signals into one communication signal. The communication ports of the leakage detector 1, the plurality of performance detectors 3, the code scanner 5, the reflection sensor 19 and other components can be connected to one of the communication ports of the distributed IO module 4. After converging the communication signals of the leakage detector 1, the plurality of performance detectors 3, the code scanner 5, the reflection sensor 19 and other components, the distributed IO module 4 can send the converged communication signals to one communication port of the controller 7 through one communication port, so that the multiple communication signals of the leakage detector 1, the plurality of performance detectors 3, the code scanner 5, the reflection sensor 19 and other components can be communicated with the controller 7 through one communication port of the controller 7, thereby reducing the occupation of the communication ports of the controller 7.
