Description

Technical Field

[0001] The present invention belongs to the technical field of detection tooling, and in particular relates to a millimeter wave obstacle avoidance radar cover detection tooling. Background Art

[0002] Due to its high operating frequency, millimeter-wave obstacle avoidance radars have strict requirements on the electromagnetic compatibility and structural accuracy of the cover: excessive errors in the cover's taper and roundness deviation will lead to increased signal insertion loss and beam pointing deviation, directly affecting the target detection distance and positioning accuracy of the obstacle avoidance system. Therefore, after the cover is produced, sampling inspection is required, such as the radar cover inspection tooling proposed in patent publication number CN208567700U.

[0003] Frustum-shaped radomes are used in millimeter-wave obstacle avoidance radars due to their excellent electromagnetic compatibility and structural strength. However, the current method of relying on manual alignment to detect their taper and roundness has significant drawbacks. Detection accuracy is easily affected by operator experience, and differences in techniques between different inspectors may cause data fluctuations, which in turn affects the traceability and stability of the test results. In addition, when inspecting radomes of different sizes, the position and angle of the inspection tool need to be adjusted multiple times. When the number of radomes to be sampled and inspected is large, it is difficult to meet the needs of rapid quality inspection on the production line.

Through this component, the radar cover can be accurately positioned to the detection center axis.

[0039] One end of the adjusting shaft 10 extends out of the tapered frame 9 and is fixedly connected to a friction plate 15. The side wall of the tapered frame 9 close to the friction plate 15 is fixedly connected to a limit frame 16. The inner wall of the limit frame 16 is fixedly connected to a limit electric push rod 17. The movable end of the limit electric push rod 17 is fixedly connected to a friction seat 18 that matches the friction plate 15, which can make the tapered frame 9 and the tapered plate 11 relatively fixed.

[0040] The operating principle of the present invention is now described as follows: the operator places the millimeter-wave radar cover to be detected into the clamping cylinder 351. Then, the operator transmits an electrical signal to the inside through the operation screen on the surface of the control cabinet 3. After receiving the electrical signal, the control cabinet 3 controls the air delivery pump 41 to work. The air delivery pump 41 delivers external gas into the annular tube 39 and delivers the gas to multiple extrusion cylinders 352 through multiple curved pipes 40, thereby increasing the air pressure on one side of the piston seat 36 in the extrusion cylinder 352. Under the action of the air pressure, the piston seat 36 The extrusion rod 37 and the extrusion seat 38 will be driven to move, and the housing will be fixed by using multiple extrusion seats 38 so that the central axis of the housing coincides with the central axis of the rotating plate 5. When the extrusion seat 38 contacts the housing, it will stop moving, while the air pump 41 is still in operation. Therefore, the air pressure inside the annular tube 39 will continue to increase. When the control cabinet 3 detects that the air pressure inside the annular tube 39 reaches the set threshold (0.2 standard atmospheric pressure) through the air pressure sensor 45, the control cabinet 3 will control the air pump 41 to stop working, and the housing can be fixed.

[0041] Then the control cabinet 3 controls the first screw linear module 81 to work, and the first screw linear module 81 drives the taper plate 11 to move toward the set position close to the cover through the movable frame 82, so that the taper plate 11 is located at the position of the central axis above the cover and stops. Then, the control cabinet 3 controls the first electric push rod 6 to work, and the first electric push rod 6 drives the taper plate 11 to move downward to the set position. Then, the control cabinet 3 controls the first screw linear module 81 to continue working, and the first screw linear module 81 will drive the taper plate 11 to move toward the direction close to the inside of the cover, so that the taper plate 11 contacts the inner wall of the cover, and after the taper plate 11 contacts the inner wall of the cover, the taper plate 11 will rotate along the adjusting shaft 10 in the taper frame 9, so that the taper plate 11 and the inner wall of the cover fit together. At the same time, the taper plate 11 will also drive the conductive rod 12 to rotate together, and the conductive rod 12 contacts the arc resistor plate 13 during the rotation process, and the control cabinet 3 uses the pressure sensor (pressure sensor) between the movable frame 82 and the taper frame 9 Figure 3 After the extrusion force between the taper plate 11 and the housing reaches the set threshold value (10N), the control cabinet 3 will control the first screw linear module 81 to stop working and control the reduction motor 4 to work. The reduction motor 4 will drive the taper plate 11 to rotate along the inner wall of the housing for one circle. At the same time, the control cabinet 3 will also control the conductive rod 12 to be electrically connected to the external power supply. The external current will be transmitted to the control cabinet 3 through the arc resistor plate 13 and the current sensor. The control cabinet 3 detects the magnitude of the current transmitted by the arc resistor plate 13, that is, The taper of the inner wall of the cover can be determined, and when a change in current is detected, it indicates that the tapers of different places inside the cover are different and there are defects. The control cabinet 3 will use the internal buzzer module to remind the operator to remove the defective cover. When the taper does not change, the control cabinet 3 will control the limit electric push rod 17 to work. The limit electric push rod 17 drives the friction seat 18 and the friction plate 15 to contact and maintain a certain pressure. The friction between the friction seat 18 and the friction plate 15 fixes the position of the adjustment shaft 10 and the taper plate 11.

[0042] When the limit electric push rod 17 finishes working, the control cabinet 3 will control the first screw linear module 81 to work in the reverse direction, and the first screw linear module 81 will drive the taper plate 11 to move to a certain position in the opposite direction through the movable frame 82, so that the upper end of the taper plate 11 is placed on one side of the inside of the cover, and the taper plate 11 and the right inner wall of the cover are in a parallel state (the taper plate 11 is located on the left side of the central axis of the cover, and the taper plate 11 is suspended in the cover and does not contact the inner wall of the cover). Then, the control cabinet 3 controls the second screw linear module 191 to work, and the second screw linear module 191 will drive the guide sleeve 192 and the detection cylinder 20 and other components to move in the direction close to the central axis of the cover, so that the first ball 23 on the surface of the detection cylinder 20 is in a parallel state. On the right side of the central axis in the cover, the control cabinet 3 then controls the second electric push rod 7 to work, so that the second electric push rod 7 drives the roundness detection component 19 to move downward to the set position, so that the roundness detection component 19 moves to the inside of the cover, and then the control cabinet 3 controls the second electric push rod 7 to stop working, and controls the second screw linear module 191 to work, and the second screw linear module 191 drives the guide sleeve 192 to continue to move toward the direction close to the taper plate 11, so that the first ball 23 contacts the surface of the taper plate 11. After the first ball 23 contacts the taper plate 11, it will drive the detection cylinder 20, the fixed plate 21 and the guide rod 22 to stop moving, and the guide sleeve 192 will continue to move under the drive of the second screw linear module 191, and the guide sleeve 192 will continue to move. The spring will be squeezed toward the sleeve 192, so that a certain elastic force is always maintained between the first ball 23 and the tapered plate 11. Then, the control cabinet 3 controls the small air pump 29 to work, and the small air pump 29 delivers external gas to the detection cylinder 20, so that the air pressure on one side of the piston plate 25 increases. Under the action of the air pressure, the piston plate 25 will drive the detection pin 24 and the second ball 26 to move, so that the second ball 26 contacts the inner wall of the cover (later, the electromagnetic block 30 can be controlled to generate magnetic force to attract the permanent magnet plate 31, the piston plate 25, the detection pin 24 and the second ball 26 to return to their original position). Then, the control cabinet 3 controls the conductive frame 27 to be electrically connected to the external power supply, and the end of the detection resistor plate 28 away from the conductive frame 27 passes through the current sensor and the control cabinet. 3 is electrically connected. At the same time, the control cabinet 3 will also control the reduction motor 4 to rotate one circle. The reduction motor 4 will drive the rotating plate 5, the first electric push rod 6 and the second electric push rod 7 to rotate together. The detection cylinder 20 and the taper plate 11 will also rotate along the central axis of the cover. The second ball 26 will rotate one circle along the inner wall of the cover. When the second ball 26 moves to the raised or recessed area in the cover, the second ball 26 will drive the piston plate 25 and the conductive frame 27 to a certain displacement through the detection pin 24, thereby changing the contact position between the conductive frame 27 and the detection resistor plate 28, causing the current signal transmitted to the control cabinet 3 by the detection resistor plate 28 to change. The control cabinet 3 will then display corresponding information on the touch screen on the surface, which is convenient for the operator to record later;

[0043] When the reduction motor 4 rotates one circle, the control cabinet 3 will control the reduction motor 4 to stop working, and control the second electric push rod 7 to drive the roundness detection component 19 to move downward to the set position. Under the action of the spring force between the fixed plate 21 and the guide sleeve 192, the first ball 23 and the detection cylinder 20 will move towards the direction of the tapered plate 11 during the downward movement (refer to Figure 10 , the lower end of the tapered plate 11 tilts to the left. When the first ball 23 continues to move downward, the first ball 23 will continue to move to the left under the action of the spring force), and the second ball 26 and the detection pin 24 will also move to the left by the same distance under the action of the tapered squeezing of the right inner wall of the cover. Therefore, in the process of the detection cylinder 20 moving downward, the detection cylinder 20 and the detection pin 24 will move to the left synchronously, so that the position between the conductive frame 27 and the detection resistor plate 28 does not change. Therefore, the change in the vertical position of the detection cylinder 20 will not affect the detection accuracy of the roundness of the cover. When the second screw linear module 191 stops working, the control cabinet 3 will repeat the above steps, control the reduction motor 4 to work, and continue to detect the roundness of other areas of the cover;

[0044] In addition, part of the gas delivered by the small air pump 29 will be delivered to the annular cavity 32 through the connecting pipe 33 and ejected through the nozzle 34, which can clean the dust and other impurities attached to the inner wall of the cover, ensuring the accuracy of the cover roundness measurement.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
