Description

Technical Field

[0001] The present invention belongs to the technical field of measurement and testing, and particularly relates to measurement through the increase and decrease rate of a fluid, and more particularly to a circulator detection tooling and a detection method thereof. Background Art

[0002] Under the combined action of a constant magnetic field and a high-frequency electromagnetic field, ferrite generates a gyromagnetic effect, which is the core principle for the circulator to achieve unidirectional transmission.

[0003] The circulator is formed by bonding a ferrite and a grounded substrate that are parallel to each other through a conductive adhesive. Under stress, the conductive adhesive may undergo creep displacement, thereby causing a change in the parallelism of the ferrite. If there is a parallelism deviation (such as inclination or local warping) between the ferrite and the grounded substrate, it will lead to an uneven distribution of the externally applied bias magnetic field.

[0004] In related technologies, image recognition detection is generally used for the ferrite to obtain its parallelism with the grounded substrate. However, this method cannot simulate the actual load conditions of the circulator, resulting in inaccurate detection data. Based on the above technical problems, those skilled in the art urgently need to design a circulator detection tooling and a detection method thereof.

[0005] 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 to constitute information on the prior art. Summary of the Invention

Specific embodiments

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying 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 shall fall within the protection scope of the present invention.

[0024] In the related art, the circulator 3 is installed on a device, and the lower surface of the grounding substrate 31 and the upper surface of the ferrite 32 are under pressure; under normal working conditions, the device does not have vibration load, and at this time, the pressure on the circulator 3 is stable; when the device vibrates, the circulator 3 will follow the vibration, resulting in unstable pressure on the circulator 3. If there is a quality problem with the circulator 3, this unstable pressure will affect the circulator 3 and make the connection of the circulator 3 unstable during subsequent use. Therefore, it is necessary to perform a simulation test on the circulator 3 before leaving the factory.

[0025] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Additionally, in the drawings, for the purpose of effectively describing the technical content, the thickness of components may be exaggerated or reduced.

[0026] The following will, with reference to the 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.

[0027] As Figure 1 shown, at least one embodiment provides a circulator detection tooling, including: a carrier plate 1, a detection mechanism, a driving mechanism 4, an inflation assembly 5, and a control module. The control module is electrically connected to the driving mechanism 4 and the inflation assembly 5.

[0028] In this embodiment, the control module may, but is not limited to, adopt a PLC; the driving mechanism 4 may, but is not limited to, adopt a three-axis slide; the inflation assembly 5 may, but is not limited to, adopt an air pump.

[0029] As Figure 2 shown, in some embodiments, the circulator 3 is bonded by a conductive adhesive 33 from a ground substrate 31 and a ferrite 32. The ground substrate 31 is located below, and the ferrite 32 is located above.

[0030] As Figure 3 、 Figure 4 shown, in some embodiments, a plurality of slots 11 for placing the circulator 3 are formed on the carrier plate 1.

[0031] As Figure 5 shown, in some embodiments, the cross-sectional shape of the slot 11 is adapted to the cross-sectional shape of the ground substrate 31. The ground substrate 31 of the circulator 3 is located within the slot 11, thereby positioning the circulator 3 and preventing the circulator 3 from translating when subjected to force.

[0032] As Figure 6 、 Figure 7 shown, in some embodiments, the detection mechanism includes: a detection cover 2. A plurality of exhaust channels 21 are formed on the detection cover 2. The inlet 211 of the exhaust channel 21 is located on the inner wall of the detection cover 2, and an independent flow sensor 23 is provided in each exhaust channel 21. Each flow sensor 23 is electrically connected to the control module.

[0033] In some embodiments, the driving mechanism 4 is connected to the detection cover 2. The control module is configured to drive the detection cover 2 to cover the slot 11 by controlling the driving mechanism 4, so that the slot 11 and the detection cover 2 form a chamber.

[0034] In some embodiments, the inflation assembly 5 is connected to the detection cover 2, and the control module is configured to inflate the detection cover 2 by controlling the inflation assembly 5.

[0035] In this embodiment, the working process of the device is as follows: The driving mechanism 4 drives the detection cover 2 to cover the slot 11 to form a detection chamber; then the inflation assembly 5 is controlled to inflate the detection cover 2, so that the air flow impacts the upper surface of the ferrite 32 in a first state, thereby simulating the ferrite 32 being subjected to an unstable pressure, and at the same time the air flow will be discharged from each exhaust channel 21; after the ferrite 32 is pressured for a period of time, the inflation assembly 5 is controlled to make the air flow impact the upper surface of the ferrite 32 in a second state, thereby simulating the ferrite 32 being subjected to a stable pressure. At this time, the flow sensors 23 in each exhaust channel 21 collect data and send it, so that the control module can judge whether the parallelism of the ferrite 32 is qualified according to the difference between the maximum flow data and the minimum flow data.

[0036] Specifically, the air flow in the first state is: an air flow with disordered flow velocity and disordered flow rate. This kind of air flow impacts the upper surface of the ferrite 32, and can simulate the ferrite 32 being subjected to an unstable pressure.

[0037] Specifically, the air flow in the second state is: an air flow with constant flow velocity and constant flow rate. This kind of air flow impacts the upper surface of the ferrite 32, and can simulate the ferrite 32 being subjected to a stable pressure.

[0038] As Figure 8 shown, in some embodiments, the ferrite 32 of the circulator 3 is located in the detection cover 2, and the inner diameter of the detection cover 2 is larger than the diameter of the ferrite 32, so as to prevent the ferrite 32 from being stuck when it is tilted under force.

[0039] As Figure 7 、 Figure 8 shown, in some embodiments, a chute 24 is opened below each inlet 211, and an "L"-shaped baffle 25 is slidably arranged in the chute 24; wherein the lower end of the "L"-shaped baffle 25 protrudes from the chute 24.

[0040] As Figure 7 shown, in some embodiments, the inlets 211 of each exhaust channel 21 are evenly distributed along the circumferential direction of the detection cover 2 and are located at the same height.

[0041] In this embodiment, when the detection cover 2 covers the slot 11, the lower end of the "L"-shaped baffle 25 abuts against the upper surface of the ferrite 32, and the upper end of the "L"-shaped baffle 25 blocks part of the inlets 211; when the parallelism of the ferrite 32 is qualified, the upper ends of each "L"-shaped baffle 25 are all at the same height, that is, the blocked areas of each inlet 211 are the same.

[0042] As Figure 9As shown, in some embodiments, when the ferrite 32 is tilted, the height of the baffle 25 on the left side decreases, and the height of the baffle 25 on the right side increases. That is, the cross-sectional area of the inlet 211 on the left side increases, and the cross-sectional area of the inlet 211 on the right side decreases, thereby causing a change in the gas flow rate in the corresponding exhaust passage 21.

[0043] In some embodiments, the control module first controls the inflation assembly 5 to impact the surface of the ferrite 32 with an airflow at a disordered flow rate and a disordered flow volume, so that the ferrite 32 is subjected to an unstable pressure, that is, simulating the force condition of the ferrite 32 during equipment vibration; subsequently, the control module controls the inflation assembly 5 to impact the surface of the ferrite 32 with an airflow at a constant flow rate and a constant flow volume, so that the ferrite 32 is subjected to an unstable pressure, that is, simulating the force condition of the ferrite 32 under normal operating conditions of the equipment; subsequently, the control module controls each flow sensor 23 to obtain the flow data in the corresponding exhaust passage, and judges whether the parallelism of the ferrite 32 is qualified according to the difference between the maximum flow data and the minimum flow data.

[0044] In this embodiment, when the parallelism of the ferrite 32 is qualified, as Figure 8 shown, the exposed areas of the inlets 211 of the respective exhaust passages 21 are the same, and the gas enters the respective exhaust passages 21 relatively uniformly. At this time, the flow data obtained by each flow sensor 23 are close to each other; when the parallelism of the ferrite 32 is unqualified, the ferrite 32 is tilted, as Figure 9 shown, the exposed areas of the inlets 211 of the respective exhaust passages 21 are different, some are large and some are small, that is, the gas flow rates entering the respective exhaust passages 21 are different. At this time, the flow data obtained by each flow sensor 23 vary greatly.

[0045] In some embodiments, the control module is configured to determine that the parallelism of the ferrite 32 is unqualified when the difference between the maximum flow data and the minimum flow data is greater than the threshold.

[0046] Optionally, the detection cover 2 is provided with ten exhaust passages 21, and ten flow sensors 23 are respectively arranged in the corresponding exhaust passages 21. That is, the control module will obtain ten flow data (for example: n1, n2, n3,..., n10). At this time, the control module judges the obtained data, subtracts the maximum flow data (for example: n3 is 7.66) from the minimum flow data (for example: n7 is 5.03) to obtain a difference (for example: the difference is 2.63), and then judges the difference with the threshold (for example: the threshold is 0.20). Since the difference 2.63 is greater than the threshold 0.20, it is determined that the parallelism of the ferrite 32 is unqualified.

[0047] In some embodiments, the control module is configured to determine that the parallelism of the ferrite 32 is qualified when the difference between the maximum flow data and the minimum flow data is less than the threshold.

[0048] Optionally, the detection cover 2 is provided with ten exhaust channels 21, and ten flow sensors 23 are respectively arranged in the corresponding exhaust channels 21, that is, the control module will obtain ten flow data (for example: n1, n2, n3, ..., n10). At this time, the control module judges the obtained data, subtracts the maximum flow data (for example: n3 is 6.13) from the minimum flow data (for example: n7 is 6.06) to obtain a difference (for example: the difference is 0.07), and then judges the difference with the threshold value (for example: the threshold value is 0.20). Because the difference 0.07 is less than the threshold value 0.20, it is judged that the parallelism of the ferrite 32 is qualified.

[0049] In some embodiments, an air inlet channel 22 is opened on the top of the detection cover 2 , the air inlet channel 22 is coaxially arranged with the slot 11 , and the inflation component 5 is connected to the air inlet channel 22 .

[0050] In some embodiments, a blocking bar 26 is disposed on the slide groove 24 , and the blocking bar 26 is used to prevent the “L”-shaped blocking piece 25 from escaping from the slide groove 24 .

[0051] At least one embodiment also provides a detection method for a circulator detection tool, comprising: placing the circulator 3 in the slot 11 of the supporting plate 1; controlling the driving mechanism 4 through the control module to drive the detection cover 2 to cover the slot 11; controlling the inflation component 5 through the control module to inflate air into the detection cover 2, so that the airflow impacts the ferrite 32 of the circulator 3 in a first state to simulate the load pressure of the ferrite 32; after the ferrite 32 is loaded with pressure, controlling the inflation component 5 through the control module to inflate air into the detection cover 2, so that the airflow impacts the ferrite 32 of the circulator 3 in a second state, and then controlling each flow sensor 23 to obtain the flow data in the corresponding exhaust channel 21, and judging whether the parallelism of the ferrite 32 is qualified according to the difference between the maximum flow data and the minimum flow data.

[0052] For the specific structure and implementation process of the circulator detection tooling, please refer to the relevant discussion in the above embodiments, which will not be repeated here.

[0053] In some embodiments, the airflow in the first state includes an airflow with a disordered flow rate and a disordered flow rate; the airflow in the second state includes an airflow with a constant flow rate and a constant flow rate.

[0054] In summary, the circulator detection tooling and detection method thereof simulates the force load on the ferrite 32 on the circulator 3 through inflation, and obtains the flow data in each exhaust channel 21 after loading to detect the parallelism of the ferrite 32, thereby preventing unqualified circulators 3 from leaving the factory.
