Description

Technical Field

[0001] The present invention belongs to the technical field of measurement and testing, and particularly relates to a technical field of measuring the physical properties of materials by optical means, and more particularly to a circulator vision detection device and its working method. Background Art

[0002] A microstrip circulator is a unidirectional microwave transmission device designed based on microwave magnetism theory, mainly used to control the flow direction of microwave signals so that they are transmitted in a fixed direction in sequence, and is widely used in fields such as communication, radar, satellite, and wireless devices.

[0003] As the core of the microstrip circulator, the microstrip lead is the transmission carrier of its microwave signal, which directly determines the directional transmission characteristics of the circulator. In related technologies, the microstrip lead needs to be aligned with multiple layers such as ceramic gaskets and permanent magnets, and the microstrip lead is exposed through a notch on the side wall of the shielding box to ensure signal transmission and prevent external magnetic field interference.

[0004] In related technologies, vision detection is used to evaluate the surface quality of the microstrip lead, but it can only detect static characteristics and cannot simulate the mechanical stress caused by vibration during actual use, resulting in the lack of strength detection.

[0005] Therefore, there is an urgent need to provide a circulator vision detection device to solve the technical problem that vision detection in related technologies cannot detect the strength of the microstrip lead.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0008] In an optional embodiment, the extrusion ring assembly includes: an extrusion part and a pressing part; The extrusion part is arranged on the periphery of the microstrip circulator accommodation groove, and the extrusion ends of the extrusion part respectively correspond to the positions of the corresponding microstrip leads; The pressing part is arranged at the negative pressure suction nozzle of the visual inspection component; where The applying part is configured to extrude the extrusion part when following the visual inspection component to fall to suck the circulator, so that the extrusion ends of the extrusion part simultaneously extrude the corresponding microstrip leads.

[0009] In an optional implementation manner, the extrusion part includes: an extrusion cross block in a horizontal posture and an extrusion vertical block in a vertical posture; The extrusion cross block is slidably arranged at the bottom of the accommodation groove, and the extrusion vertical block is located at the end of the extrusion cross block; where The extrusion vertical block is configured to move downward to push the extrusion cross block forward, and further push the microstrip lead to deform.

[0010] In an optional implementation manner, the extrusion cross block includes a rigid push block and an elastic push block; where The elastic push block is slidably arranged inside the rigid push block, and a protrusion extending out of the inside and outside of the rigid push block is arranged on the elastic push block; The rigid push block is configured to push and extrude the microstrip lead, and the elastic push block is configured to extend into the bottom of the circulator to lift the circulator; where The protrusion is configured to move downward when receiving the extrusion force after the deformation recovery of the microstrip lead, so that the front end of the elastic push block continues to extend forward to extend into the bottom of the circulator.

[0011] In an optional implementation manner, an elastic push block extension hole is opened at the front end of the rigid push block, and the rear end of the rigid push block is arranged in an inclined surface; and The lower end of the extrusion vertical block is also arranged in an inclined surface, and the inclined surfaces of the two are adapted to each other, so that the extrusion vertical block moves downward to push the rigid push block forward.

[0012] In an optional implementation manner, a connecting ring is further arranged at the top of the extrusion vertical block, and the connecting ring is configured to connect several extrusion vertical blocks together; and The position of the pressing part corresponds to the position of the connecting ring.

[0013] In an optional implementation manner, the pressing part is sleeved on the outside of the negative pressure suction nozzle, and the bottom surface of the pressing part is lower than the bottom surface of the negative pressure suction nozzle; where The distance between the bottom surface of the pressing part and the bottom surface of the negative pressure suction nozzle is the same as the front end thickness of the elastic push block.

[0014] In an optional implementation manner, the visual inspection component includes: a 3D scanning camera; The negative pressure suction nozzle is arranged on the front side wall of the 3D scanning camera; and The negative pressure suction nozzle is connected to the front side wall of the 3D scanning camera through a cylinder.

[0015] The embodiment of the present disclosure also provides a working method for a circulator vision detection device, including: using the above-mentioned circulator vision detection device; and Grasping the circulator through the negative pressure suction nozzle; Collecting an image of the grasped circulator through the 3D scanning camera; Comparing the collected image with a standard image to determine whether the quality of the grasped circulator is qualified.

[0016] In an optional implementation manner, the method for grasping the circulator through the negative pressure suction nozzle includes: When the negative pressure suction nozzle moves downward, the pressing part arranged on its outer side first pushes the extrusion part to extrude the microstrip lead of the circulator; where If the microstrip lead can still recover its deformation after being extruded, then at this time the microstrip lead will contact and squeeze the protrusion of the elastic push block, so that the front end of the elastic push block extends forward to extend to the bottom of the circulator to lift the circulator, and then the negative pressure suction nozzle contacts the top wall of the circulator, thereby sucking up the circulator; If the microstrip lead cannot recover its deformation after being extruded, then at this time the microstrip lead cannot contact the protrusion, the circulator cannot be displaced, and there is a gap between the circulator and the negative pressure suction nozzle, so that the negative pressure fails and the circulator cannot be sucked up.

[0017] The beneficial effect of the present invention is that the circulator vision detection device of the present invention carries and conveys a plurality of circulators to be tested through the provided circulator carrier plate, applies extrusion to the microstrip leads of the circulators through the extrusion ring assembly, and performs different treatments on the circulators according to the recovery degree of the microstrip leads after being extruded. If the microstrip lead cannot recover its deformation, at this time the elastic push block of the extrusion ring assembly cannot be triggered, and further the circulator cannot be pushed upward, so that the adsorption force of the negative pressure suction nozzle cannot be generated, and the circulator cannot be sucked up. For the circulator, if such a problem occurs, it can also be determined that the strength of the microstrip lead of the circulator is unqualified, and there is no need to perform subsequent vision detection. Through the extrusion ring assembly, the simulation of the application of the strength of the microstrip lead of the circulator and the recovery detection after the application are realized, improving the detection efficiency and the detection accuracy at the same time.

[0023] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. In addition, in the figures, for the effective description of the technical content, the thickness of components may be exaggerated or reduced.

[0025] The following will, with reference to the accompanying drawings, elaborate on some embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0026] The structural composition of a microstrip circulator mainly includes a ferrite material, a microstrip line, and a ground plane. Its core part is usually composed of a central ferrite disk or cylinder, surrounded by three microstrip lines that are symmetrically arranged at 120° to each other. These microstrip lines are connected to the ferrite disk through metal sheets to form a closed loop. For microstrip leads, in addition to their traditional electrical performance tests, relevant mechanical performance detections should also be carried out on them. In related technologies, visual inspection is used to detect the flatness and phase angle of microstrip lines. However, when the circulator is actually in use, the microstrip leads may be compressed due to equipment vibration and other reasons. Therefore, with the improvement of product quality requirements, the strength of the microstrip leads of the circulator has also become a parameter that needs to be detected.

[0027] See Figure 1 , Figure 1 which shows a visual inspection device for a circulator, including: a workbench 1, on which a conveying track for conveying the circulator 5 is provided; a circulator 5 carrier plate 2, arranged on the bottom rail 11 of the conveying track, and a plurality of circulator 5 receiving grooves are formed on the circulator carrier plate 2; and a pressing ring assembly 3, configured to apply pressure to the microstrip lead 50 extending out of the circulator 5; and a visual inspection assembly 4, arranged on the top rail 12 of the conveying track; wherein the visual inspection assembly 4 is configured to suck up the circulator 5 in the corresponding receiving groove and then obtain the surface image information of the circulator 5, and determine whether the strength of the microstrip lead 50 of the measured circulator 5 is qualified according to the surface image information.

[0028] In some embodiments, the conveying track is configured to include a bottom rail 11 and a top rail 12. The circulator 5 carrier plate 2 is arranged on the bottom rail 11, and the visual inspection assembly 4 is arranged on the top rail 12. Both are configured to be movable along the corresponding tracks, so as to realize the image acquisition and detection of the circulator 5 on the circulator 5 carrier plate 2 by the visual inspection assembly 4 in sequence.

[0029] See Figure 2 , Figure 3 and Figure 5, Specifically, a number of extrusion ring assemblies 3 are further provided on the circulator carrier plate 2. The extrusion ring assemblies 3 are provided corresponding to the accommodating grooves of each circulator 5. The reason for adopting this extrusion method is also that the ferrite inside the circulator 5 is a fragile material and is very sensitive to mechanical stress. In this regard, when the extrusion part 31 in the extrusion ring assembly 3 does not exert extrusion on the microstrip lead 50 of the circulator 5, it plays an elastic supporting role for the circulator 5. Because the extrusion part 31 is located at the bottom of the circulator 5, and the microstrip lead 50 of the circulator 5 is in contact with the extrusion part 31, and a spring (not shown in the figure) is provided at the end of the extrusion cross block 311 of the extrusion part 31. In this regard, if mechanical vibration occurs when the circulator 5 moves along the bottom rail 11, it can be absorbed by the spring, thereby preventing the circulator 5 from bearing mechanical stress. In the related art, a clamping method is used to fix the circulator 5. For example, an elastic gasket is coated on the inner wall of the accommodating groove, and then the circulator 5 is snapped into the accommodating groove. However, another significant problem is found in actual application of this method, that is, when the circulator 5 is grasped by a negative pressure suction nozzle, the fitting of the circulator 5 with the side wall of the accommodating groove results in a very large frictional resistance. This frictional resistance will cause a sudden change in the pulling force when the negative pressure suction nozzle sucks, and at this time, the change in the pulling force will also be transmitted to the inside of the circulator 5, and the ferrite may be damaged.

[0030] In some embodiments, the extrusion ring assembly 3 includes: an extrusion part 31 and a pressing part 32; the extrusion part 31 is arranged on the periphery of the accommodating groove of the microstrip circulator 5, and the extrusion ends of the extrusion part 31 correspond to the positions of the corresponding microstrip leads 50 respectively; the pressing part 32 is arranged at the negative pressure suction nozzle of the visual detection assembly 4; wherein the applying part is configured to extrude the extrusion part 31 when following the visual detection assembly 4 to fall to suck the circulator 5, so that the extrusion ends of the extrusion part 31 simultaneously extrude the corresponding microstrip leads 50.

[0031] See Figure 2 , in this embodiment, the pressing part 32 is arranged at the negative pressure suction nozzle 42. In this regard, when the negative pressure suction nozzle 42 moves downward, the pressing part 32 contacts and pushes the extrusion vertical block 312 of the extrusion part 31 to move downward. After the extrusion vertical block 312 moves downward, it will push the extrusion cross block 311 to move forward, and the forward movement of the extrusion cross block 311 extrudes the corresponding microstrip lead 50, causing the microstrip lead 50 to undergo extrusion deformation.

[0032] Specifically, the extrusion cross block 311 further includes a rigid push block 315 and an elastic push block 316; wherein the elastic push block 316 is slidably disposed inside the rigid push block 315, and a protrusion 314 extending out of the rigid push block 315 is provided on the elastic push block 316; the rigid push block 315 is configured to push the extrusion microstrip lead 50, and the elastic push block 316 is configured to extend into the bottom of the circulator 5 to lift the circulator 5; wherein the protrusion 314 is configured to move downward when subjected to the extrusion force after the deformation recovery of the microstrip lead 50, so that the front end of the elastic push block 316 continues to extend forward to extend into the bottom of the circulator 5.

[0033] As a preference of the embodiment, before the circulator 5 is detected, the circulator 5 is statically placed in the receiving groove. At this time, the front end of the rigid push block 315 contacts the microstrip lead 50. When the circulator 5 is detected, the rigid push block 315 will move forward. Since there is a gap between the vertical end of the microstrip lead 50 and the bottom surface of the circulator 5, when the rigid push block 315 pushes the microstrip lead 50 forward, the microstrip lead 50 undergoes a swinging deformation until the gap between the vertical end of the microstrip lead 50 and the bottom surface of the circulator 5 increases to allow the rigid push block 315 to pass through. After the rigid push block 315 passes through, if the microstrip lead 50 can immediately return to its original state, it will swing back to its original position. At this time, the vertical end of the microstrip lead 50 will contact the protrusion 314 of the elastic push block 316. At this time, the microstrip lead 50 squeezes the protrusion 314 of the elastic push block 316, and the elastic push block 316 is pressed to move forward and extends under the bottom surface of the circulator 5, thereby lifting the circulator 5, so that the top surface of the circulator 5 contacts the negative pressure suction nozzle and can be sucked up by the suction force of the negative pressure suction nozzle. If the microstrip lead 50 cannot return to its original state, the protrusion 314 cannot be triggered, so that the circulator 5 will not be lifted but will be further clamped by the rigid push block 315. At this time, there is still a gap between the negative pressure suction nozzle and the circulator 5, and the circulator 5 is still clamped. At this time, the negative pressure suction force of the negative pressure suction nozzle cannot suck up the circulator 5. In this way, the strength application and real-time detection of the microstrip lead 50 can be realized.

[0034] See Figure 6 , as an alternative embodiment, an elastic push block 316 extending hole is provided at the front end of the rigid push block 315, and the rear end of the rigid push block 315 is provided with an inclined surface; and the lower end of the extrusion vertical block 312 is also provided with an inclined surface, and the two inclined surfaces are adapted to each other, so that the extrusion vertical block 312 moves downward to push the rigid push block 315 forward.

[0035] As an alternative embodiment, a connecting ring 313 is further provided at the top of the extrusion vertical block 312, and the connecting ring 313 is configured to connect a plurality of extrusion vertical blocks 312 together; and the position of the pressing portion 32 corresponds to the position of the connecting ring 313.

[0036] Specifically, the provided connecting ring 313 is used to connect several extrusion vertical blocks 312 together, so as to achieve the simultaneous and same-speed descent of several extrusion vertical blocks 312. The reason for adopting this method is that the rigid push block 315 is located at the bottom of the circulator 5. The reason for choosing to apply pressure here is that this place is far from the connection between the microstrip lead 50 and the ferrite. Applying pressure is not likely to affect the main resonance structure inside the circulator 5. However, because the rigid push block 315 is located at the bottom of the circulator 5, if it does not extrude simultaneously, the circulator 5 is likely to be unevenly stressed, and then the rigid push block 315 will push the circulator 5 to move, so that the microstrip lead 50 cannot be smoothly pushed to deform.

[0037] In some embodiments, the pressing part 32 is sleeved outside the negative pressure suction nozzle, and the bottom surface of the pressing part 32 is lower than the bottom surface of the negative pressure suction nozzle; the distance between the bottom surface of the pressing part 32 and the bottom surface of the negative pressure suction nozzle is the same as the front-end thickness of the elastic push block 316, that is, after the elastic push block 316 is inserted into the bottom of the circulator 5, the height at which the circulator 5 is lifted just enables the circulator 5 to contact the negative pressure suction nozzle.

[0038] As an alternative implementation, the negative pressure suction nozzle is a vacuum-type negative pressure suction nozzle, that is, the negative pressure effect can be achieved only when the circulator 5 contacts the suction cup of the negative pressure suction nozzle.

[0039] In some embodiments, the visual detection component 4 includes: a 3D scanning camera 41; the negative pressure suction nozzle is arranged on the front side wall of the 3D scanning camera; and the negative pressure suction nozzle is connected to the front side wall of the 3D scanning camera through a cylinder 43. Then, under the action of the cylinder, the negative pressure suction nozzle is driven to move up and down to grab the circulator 5 for the 3D scanning camera to collect images.

[0040] Specifically, the reason for further judging the strength of the microstrip lead of the circulator that can be lifted by collecting images is that by using the extrusion ring assembly 3 to apply pressure to the microstrip lead of the circulator, clamping the circulator that cannot be restored, and normally grasping the circulator that can be restored, only the simulation and preliminary inspection of the strength are realized. Since the convex width of the elastic push block is greater than the width of the microstrip lead of the circulator, there will still be some circulators whose microstrip leads have a slight shortage in the recovery amount despite being lifted. For this, a visual detection method is used for more precise detection. By comparing the collected image with the standard image, it is judged whether the strength of the microstrip lead of the circulator is qualified. And the methods of image collection and analysis include but are not limited to the methods of image acquisition and analysis in the prior art.

[0041] On the other hand, this embodiment also provides a working method for a circulator vision detection device, including: using the above-mentioned circulator vision detection device; and grasping the circulator 5 through a negative pressure suction nozzle; collecting an image of the grasped circulator 5 through a 3D scanning camera; and comparing the collected image with a standard image to determine whether the quality of the grasped circulator 5 is qualified.

[0042] Specifically, the method for grasping the circulator 5 through the negative pressure suction nozzle includes: when the negative pressure suction nozzle moves downward, the pressing portion 32 provided on its outer side first pushes the pressing portion 31 to press the microstrip lead 50 of the circulator 5; if the microstrip lead 50 can still recover its deformation after being pressed, then at this time the microstrip lead 50 will contact and press the protrusion 314 of the elastic push block 316, so that the front end of the elastic push block 316 extends forward to extend to the bottom of the circulator 5 to lift the circulator 5, and then the negative pressure suction nozzle contacts the top wall of the circulator 5, thereby sucking up the circulator 5; if the microstrip lead 50 cannot recover its deformation after being pressed, then at this time the microstrip lead 50 cannot contact the protrusion 314, the circulator 5 cannot be displaced, and there is a gap between the circulator 5 and the negative pressure suction nozzle, so that the negative pressure fails and the circulator 5 cannot be sucked up.

[0043] In summary, the circulator 5 vision detection device of the present invention uses the circulator 5 carrier plate 2 provided to carry and convey a plurality of circulators 5 to be tested, applies extrusion to the microstrip lead 50 of the circulator 5 through the extrusion ring assembly 3, and performs different treatments on the circulator 5 according to the recovery degree of the microstrip lead 50 after being extruded. If the microstrip lead 50 cannot recover its deformation, the elastic push block 316 of the extrusion ring assembly 3 cannot be triggered at this time, and then the circulator 5 cannot be pushed upward, so that the adsorption force of the negative pressure suction nozzle cannot be generated, and the circulator 5 cannot be sucked up. For the circulator 5, if such a problem occurs, it can also be determined that the strength of the microstrip lead of the circulator 5 is unqualified, and there is no need to perform subsequent vision detection. The extrusion ring assembly 3 realizes the simulation of the application of the strength of the microstrip lead 50 of the circulator 5 and the recovery detection after the application, improving the detection efficiency and the detection accuracy at the same time.
