Description

Technical Field

[0001] The present invention relates to the technical field of superconducting material detection, and in particular to a superconducting material detection device and a detection method thereof. Background Art

[0002] The detection of superconducting materials is a comprehensive process, covering multiple aspects to ensure the superconducting performance and quality of the materials. Among them, the Meissner effect is an important feature of the superconducting state, which reveals the unique behavior of superconductors in a magnetic field. When a superconductor enters the superconducting state, it repels the magnetic field, making the magnetic flux density zero. By verifying the Meissner effect, it can be determined whether the superconducting material truly has superconducting properties, thereby ensuring the quality of the material. This is crucial to ensuring the performance and reliability of superconducting devices.

[0003] The core of the existing method for detecting the Meissner effect of superconducting materials lies in accurately observing the repulsion behavior of superconductors to external magnetic fields below a specific temperature (superconducting critical temperature). This repulsion causes the magnetic field to be unable to penetrate the interior of the superconductor, and forms a layer of obvious magnetic field repelled area on its surface, which is a direct manifestation of the Meissner effect. However, directly measuring this magnetic field change places extremely high demands on experimental conditions and measurement equipment, including but not limited to high-precision magnetic field generators, high-sensitivity magnetic field detectors, and stable low-temperature environment control systems. These high-demand experimental equipment and conditions not only increase the complexity and difficulty of the experiment, but also significantly increase the cost of the experiment. Due to funding, technology or space constraints, many laboratories find it difficult to bear such high experimental costs, thereby limiting the popularization and in-depth study of the Meissner effect of superconducting materials. Based on this, the present invention purposely provides a superconducting material detection device and a detection method thereof that can indirectly prove the Meissner effect of superconducting materials at a low cost. Summary of the invention

When the superconducting material body contacts the first marking assembly, it is a qualified mark, and it is pushed into the first outlet by the pushing assembly. When the superconducting material body contacts the second marking assembly, it is an unqualified mark, and it is pushed into the second outlet by the pushing assembly.

[0006] As a further solution of the present invention: the first marking assembly includes a first marking plate and a second marking plate, the second marking assembly includes a third marking plate, the first marking plate and the second marking plate are both fixedly mounted on the first inspection plate, the first marking plate is located above the second marking plate, and its thickness is consistent with the thickness of the superconducting material body, the third marking plate is fixedly mounted on the second inspection plate, when the superconducting material body contacts the first marking plate and the second marking plate, it is attached with a qualified mark; when the superconducting material body contacts the third marking plate, it is attached with an unqualified mark.

[0007] As a further solution of the present invention: the first marking assembly also includes a first pressure sensor, and the second marking assembly also includes a second pressure sensor. The first pressure sensor and the second pressure sensor are respectively connected to the controller. When the superconducting material body contacts the first marking plate and the second marking plate, the first pressure sensor responds, and the controller controls the rotating bracket to move to the first outlet and turn off the electromagnet, and pushes the superconducting material body into the first outlet through the pushing assembly; when the superconducting material body contacts the third marking plate, the second pressure sensor responds, and the controller controls the rotating bracket to move to the second outlet and turn off the electromagnet, and pushes the superconducting material body into the second outlet through the pushing assembly.

[0012] A detection method for a superconducting material detection device, the method is applied to a superconducting material detection device as described above, the method comprising the following steps: Step S1: The controller controls the rotating bracket to rotate through the driving source so that the electromagnet is located below the loading assembly, and the superconducting material body is placed on the electromagnet through the loading assembly; Step S2: the electromagnet rotates to the cooling component, and the electromagnet is turned on. At this time, the superconducting material body is located in the magnetic field generated by the electromagnet. Under the action of the cooling component, the temperature of the superconducting material body drops below the critical temperature, that is, magnetic suspension is achieved through the Meissner effect. At this time, the superconducting material body moves synchronously with the electromagnet. Step S3: The electromagnet rotates to the first inspection plate. If the superconducting material body is qualified, that is, only a small part of the magnetism of the superconducting material body can pass through the superconducting material body, or even the superconducting material body is completely antimagnetic, the superconducting material body is suspended high enough to contact the first marking component on the first inspection plate, and is attached with a qualified mark, and then discharged from the first outlet. If the superconducting material body is unqualified, it passes under the first inspection plate; Step S4: The unqualified superconducting material body means that its anti-magnetism is insufficient, which is specifically manifested by its low suspension height. At this time, the superconducting material body is rotated to the second detection plate with the electromagnet, and it will contact the second marking component on the second detection plate, and be attached with an unqualified mark, and then discharged from the second outlet; Step S5: the electromagnet rotates again to the bottom of the loading assembly, and steps S1 to S4 are repeated to carry out the next round of testing of the new superconducting material body.

[0013] Beneficial effects of the present invention: 1. In the present invention, by controlling the experimental conditions, it is ensured that the temperature and magnetic field strength of the superconducting material body remain constant. Under this condition, the magnetic suspension height of the superconducting material body will directly reflect whether its anti-magnetic performance is qualified, that is, the strength of the Meissner effect. The first detection plate and the second detection plate are cleverly arranged on the path through which the superconducting material body rotates. The two detection plates automatically judge whether its anti-magnetic performance is qualified based on the height of the superconducting material body suspended in the magnetic field. The first detection plate is used to attach a qualified mark to the qualified superconducting material body, and the superconducting material body does not reach the height of the first detection plate, that is, the anti-magnetic performance is poor, and it will be attached with an unqualified mark by the second detection plate. In this way, not only can the test results be more intuitive and easy to understand, but also no complicated instrument measurement is required, and the superconducting material body can be directly classified to distinguish whether the superconducting material body is qualified or not; 2. In the present invention, when the superconducting material body is completely anti-magnetic, its suspension height reaches the highest, and at this time the superconducting material body will only contact the first marking plate, so that a single first marking plate mark is attached; while only a small part of the magnetism of the superconducting material body can pass, although its suspension height is qualified, the height has not reached the highest, and at this time the superconducting material body will contact both the first marking plate and the second marking plate, so that two marks are attached, and the lower the mark height of the second marking plate on the superconducting material body, the stronger its anti-magnetism; and when the anti-magnetism of the superconducting material body is unqualified, it can only be attached with a single mark by the third marking plate, so that the use of intuitive marking method reduces the demand for complex and expensive detection equipment, and different marks can be attached according to different heights of the magnetic suspension of the superconducting material body, which directly shows the strength of the anti-magnetism of the superconducting material body, and can also greatly improve the efficiency of screening and classification on the detection production line; 3. In the present invention, by arranging the annular cooling belt, it can be ensured that when the superconducting material body moves in a suspended state, its moving range can be maintained at a low temperature, ensuring that the temperature of the superconducting material body is always below the critical temperature during the detection stage, avoiding the problem of inaccurate detection caused by temperature increase, and the joint cooling of the superconducting material body by the annular cooling belt and the cooling component can accelerate the cooling speed of the superconducting material body.

DETAILED DESCRIPTION

[0017] 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.

[0018] See also Figure 1-Figure 8 As shown, the present invention is a superconducting material detection device, comprising: The testing table 1 is divided into a preparation area 101 and a testing area 102, and is provided with a first outlet 103 and a second outlet 104. A loading component 2 and a cooling component 3 are provided in the preparation area 101, and a first testing plate 4 and a second testing plate 5 are provided in the testing area 102. The first outlet 103 is located between the cooling component 3 and the first testing plate 4, and the second outlet 104 is located between the first testing plate 4 and the second testing plate 5. A first marking component is provided on the first testing plate 4, and a second marking component is provided on the second testing plate 5. The horizontal height of the first marking component is higher than the horizontal height of the second marking component. The line connecting the loading component 2 and the first testing plate 4 crosses the line connecting the cooling component 3 and the second testing plate 5. A rotating bracket 6 is coaxially arranged with the detection platform 1 and rotatably mounted on the detection platform 1. The rotating bracket 6 is driven to rotate by a driving source. An electromagnet 7 is fixedly mounted on the rotating bracket 6, and a pushing assembly is arranged on the rotating bracket 6. The electromagnet 7, the pushing assembly and the driving source are all connected to the controller. When the driving source drives the rotating bracket 6 to rotate, the electromagnet 7 passes under the feeding assembly 2, the cooling assembly 3, the first detection plate 4 and the second detection plate 5 in sequence; and The superconducting material body 8, when the electromagnet 7 rotates to the loading component 2, the superconducting material body 8 is placed on the electromagnet 7 through the loading component 2, and when the electromagnet 7 rotates to the cooling component 3, the controller controls the electromagnet 7 to turn on, so that the superconducting material body 8 is superconductingly magnetically suspended, and then the electromagnet 7 passes through the first detection plate 4 and the second detection plate 5 in sequence. When the superconducting material body 8 contacts the first marking component, it is a qualified mark, and it is pushed into the first outlet 103 by the pushing component. When the superconducting material body 8 contacts the second marking component, it is an unqualified mark, and it is pushed into the second outlet 104 by the pushing component.

[0019] In one case of this embodiment, the cooling component 3 can be a liquid nitrogen cooling device, direct refrigerant cooling, etc., the driving source can be a servo motor, a servo motor and other components, and other mechanisms capable of realizing rotational motion can also be selected. This embodiment is not specifically limited here; it should be noted that the electromagnet 7 and the controller described in the present invention are all prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0020] In actual application, the detection process of the superconducting material body 8 is as follows: Figure 4-Figure 7 As shown, first, the controller controls the rotation of the rotating bracket 6 through the driving source, so that the electromagnet 7 is located below the loading component 2. At this time, the superconducting material body 8 is placed on the electromagnet 7 through the loading component 2. When the electromagnet 7 rotates to the cooling component 3, the controller turns on the electromagnet 7. At this time, the superconducting material body 8 is located in the magnetic field generated by the electromagnet 7, and the temperature of the superconducting material body 8 will drop below the critical temperature under the action of the cooling component 3. At this time, the resistance of the superconducting material body 8 suddenly disappears and enters a zero resistance state. At this time, the magnetic flux lines inside the superconducting material body 8 are repelled, generating a reverse magnetic field, which offsets the original magnetic field to form a repulsive force, thereby making the superconducting material body 8 magnetically suspended. At this time, the superconducting material body 8 will move synchronously with the electromagnet 7; If the superconducting material body 8 is qualified, when it is magnetically suspended, only a small part of the magnetism can pass through, and the superconducting material body 8 may even appear completely anti-magnetic, that is, the magnetism cannot pass through. Specifically, the height of the superconducting material body 8 suspended in the air is high enough to contact the first marking component on the first detection plate 4, and be attached with a qualified mark, and then be discharged from the first outlet 103. If the superconducting material body 8 is unqualified, it means that its anti-magnetism is insufficient, then the suspension height of the superconducting material body 8 is low, and it will pass under the first detection plate 4, and then come to the second detection plate 5, and contact the second marking component on the second detection plate 5, and be attached with an unqualified mark, and then be discharged from the second outlet 104, and then the electromagnet 7 is turned to the bottom of the loading component 2 again, and the new superconducting material body 8 can be placed on the electromagnet 7.

[0021] By controlling the experimental conditions, it is ensured that the temperature and magnetic field strength of the superconducting material body 8 remain constant. Under this condition, the magnetic levitation height of the superconducting material body 8 will directly reflect whether its anti-magnetic performance is qualified, that is, the strength of the Meissner effect. The first detection plate 4 and the second detection plate 5 are cleverly arranged on the path through which the superconducting material body 8 rotates. Both automatically judge whether its anti-magnetism is qualified based on the height of the superconducting material body 8 suspended in the magnetic field. The first detection plate 4 is used to attach a qualified mark to the qualified superconducting material body 8. If the superconducting material body 8 does not reach the height of the first detection plate 4, that is, the anti-magnetism is poor, it will be attached with an unqualified mark by the second detection plate 5. This not only makes the test results more intuitive and easy to understand, but also does not require complex instrument measurements, and can directly classify the superconducting material body 8 to distinguish whether the superconducting material body 8 is qualified or not.

[0022] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the first marking component includes a first marking plate 401 and a second marking plate 402, and the second marking component includes a third marking plate 501. The first marking plate 401 and the second marking plate 402 are both fixedly mounted on the first inspection plate 4, the first marking plate 401 is located above the second marking plate 402, and its thickness is consistent with the thickness of the superconducting material body 8, and the third marking plate 501 is fixedly mounted on the second inspection plate 5. When the superconducting material body 8 contacts the first marking plate 401 and the second marking plate 402, it is attached with a qualified mark; when the superconducting material body 8 contacts the third marking plate 501, it is attached with an unqualified mark.

[0023] In one case of this embodiment, the first marking plate 401, the second marking plate 402 and the third marking plate 501 can use paint plates of different colors to paint different heights of the superconducting material body 8 with different colors, so as to distinguish the specific category of the superconducting material body 8.

[0024] In actual application of this embodiment, when the superconducting material body 8 is completely antimagnetic, its suspension height reaches the highest, and at this time the superconducting material body 8 will only contact the first marking plate 401, so that a single first marking plate 401 mark is attached; and when only a small part of the magnetism of the superconducting material body 8 can pass, although its suspension height is qualified, the height does not reach the highest. At this time, the superconducting material body 8 will contact both the first marking plate 401 and the second marking plate 402, so that two marks of the first marking plate 401 and the second marking plate 402 are attached, and the second marking plate 402 mark can be attached according to the maximum mark of the second marking plate 402 on it. The strength of the anti-magnetism of the superconducting material body 8 is judged from a high position, that is, the lower the mark height of the second mark plate 402 on the superconducting material body 8, the stronger its anti-magnetism; and when the anti-magnetism of the superconducting material body 8 is unqualified, it can only contact with the third mark plate 501 and be attached with a single third mark plate 501 mark. The use of such an intuitive marking method reduces the demand for complex and expensive testing equipment. Different marks can be attached according to the different heights of the magnetic suspension of the superconducting material body 8, which directly shows the strength of the anti-magnetism of the superconducting material body 8, and can also greatly improve the efficiency of screening and classification on the testing production line.

[0025] like Figure 1-Figure 3 As shown, as a preferred embodiment of the present invention, the first marking component also includes a first pressure sensor 403, and the second marking component also includes a second pressure sensor 502. The first pressure sensor 403 and the second pressure sensor 502 are respectively connected to the controller. When the superconducting material body 8 contacts the first marking plate 401 and the second marking plate 402, the first pressure sensor 403 responds, and the controller controls the rotating bracket 6 to move to the first outlet 103 and turn off the electromagnet 7, and pushes the superconducting material body 8 into the first outlet 103 through the pushing assembly; when the superconducting material body 8 contacts the third marking plate 501, the second pressure sensor 502 responds, and the controller controls the rotating bracket 6 to move to the second outlet 104 and turn off the electromagnet 7, and pushes the superconducting material body 8 into the second outlet 104 through the pushing assembly.

[0026] In one case of this embodiment, it should be noted that the first pressure sensor 403 and the second pressure sensor 502 described in the present invention are both prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0027] In actual application of this embodiment, when the superconducting material body 8 contacts the first marking plate 401 and the second marking plate 402, pressure will be generated, and the first pressure sensor 403 can sense the pressure generated by the contact, and control the rotating bracket 6 to move to the first outlet 103 and close the electromagnet 7 through the controller. At this time, the magnetic field is lost, and the electromagnet 7 will fall on the superconducting material body 8. At this time, the superconducting material body 8 can be pushed into the first outlet 103 by the pushing assembly. Similarly, when the superconducting material body 8 contacts the third marking plate 501, the pressure generated will cause the second pressure sensor 502 to respond accordingly, and finally the superconducting material body 8 will be discharged through the second outlet 104. In this way, when the superconducting material body 8 contacts the detection assembly, it is marked with a pass or fail mark, and one of the first pressure sensor 403 and the second pressure sensor 502 can immediately sense the contact pressure. This instant response ensures that the system can quickly identify the detection result of the superconducting material body 8, that is, whether it is qualified, and make a corresponding response, so that the superconducting material body 8 is discharged through the corresponding first outlet 103 or second outlet 104.

[0028] like Figure 4-Figure 7 As shown, as a preferred embodiment of the present invention, the pushing assembly includes an electric cylinder 601 and a pushing plate 602. The electric cylinder 601 is fixedly mounted on the rotating bracket 6 and is connected to the controller. The pushing plate 602 is fixedly connected to the movable end of the electric cylinder 601. When the electric cylinder 601 is extended, the pushing plate 602 will push the superconducting material body 8 on the electromagnet 7 down.

[0029] In one case of this embodiment, the push plate 602 is in contact with the top surface of the electromagnet 7. It should be noted that the electric cylinder 601 described in the present invention is a prior art, and the present invention does not improve it. Therefore, there is no need to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0030] In actual application of this embodiment, when the electric cylinder 601 is extended, the push plate 602 will push out the superconducting material body 8 located on the electromagnet 7, thereby completing the unloading of the superconducting material body 8. At the same time, the push plate 602 will also clean the top surface of the electromagnet 7 to ensure the cleanliness of the electromagnet 7.

[0031] like Figure 1 As shown, as a preferred embodiment of the present invention, an annular cooling belt 9 is fixedly installed in the test platform 1, the annular cooling belt 9 is coaxially arranged with the test platform 1, and is located above the electromagnet 7, and the superconducting material body 8 is located between the cooling component 3 and the annular cooling belt 9.

[0032] In one case of this embodiment, it should be noted that the annular cooling belt 9 described in the present invention is a prior art, and the present invention does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, and it does not affect the integrity of the present invention.

[0033] In actual application, the annular cooling belt 9 is arranged to ensure that the superconducting material body 8 can be kept in a low temperature state within its moving range when moving in a suspended state, and the temperature of the superconducting material body 8 is always below the critical temperature during the detection stage, thereby avoiding the problem of inaccurate detection caused by temperature increase. In addition, the annular cooling belt 9 and the cooling component 3 jointly cool the superconducting material body 8, which can accelerate the cooling speed of the superconducting material body 8.

[0034] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the loading assembly 2 includes a loading platform 201, a chute 202 and a loading port 203. The loading platform 201 is fixedly installed on the inspection platform 1, the chute 202 is opened on the top of the loading platform 201, the loading port 203 is opened in the chute 202, and the running track of the electromagnet 7 is located below the loading port 203.

[0035] In actual application of this embodiment, when the electromagnet 7 moves to below the loading port 203, the superconducting material body 8 is placed in the slide groove 202 and pushed to the loading port 203. The superconducting material body 8 will fall directly onto the electromagnet 7 through the loading port 203. There is no need to manually place the superconducting material body 8 on the electromagnet 7 and adjust the position, which improves the loading speed.

[0036] like Figure 8 As shown, as a preferred embodiment of the present invention, a temperature-insulating cover 10 is installed on the detection platform 1 , and a feed port 1001 is opened on the temperature-insulating cover 10 , and the feed port 1001 is connected to the chute 202 .

[0037] In actual application, the present embodiment can maintain the cold air generated by the cooling component 3 in the thermal insulation cover 10 through the setting of the thermal insulation cover 10, reduce the loss of cold air, and ensure that the superconducting material body 8 is always in a low-temperature environment. At the same time, the superconducting material body 8 can be put into the chute 202 through the feed port 1001 to carry out the normal loading process.

[0038] See also Figure 1-Figure 6 As shown, the present invention is a detection method for a superconducting material detection device, the method is applied to a superconducting material detection device as described in the above embodiment, and the method comprises the following steps: Step S1: The controller controls the rotating bracket 6 to rotate through the driving source so that the electromagnet 7 is located below the loading assembly 2, and the superconducting material body 8 is placed on the electromagnet 7 through the loading assembly 2; Step S2: the electromagnet 7 rotates to the cooling component 3, and the electromagnet 7 is turned on. At this time, the superconducting material body 8 is located in the magnetic field generated by the electromagnet 7. Under the action of the cooling component 3, the temperature of the superconducting material body 8 drops below the critical temperature, that is, magnetic suspension is achieved through the Meissner effect. At this time, the superconducting material body 8 moves synchronously with the electromagnet 7. Step S3: the electromagnet 7 rotates to the first inspection plate 4. If the superconducting material body 8 is qualified, that is, only a small part of the magnetism of the superconducting material body 8 can pass through the superconducting material body 8, or even the superconducting material body 8 is completely antimagnetic, specifically, the height of the superconducting material body 8 suspended in the air is high enough to contact the first marking component on the first inspection plate 4, and be attached with a qualified mark, and then discharged from the first outlet 103. If the superconducting material body 8 is unqualified, it passes through the bottom of the first inspection plate 4; Step S4: The unqualified superconducting material body 8 means that its anti-magnetism is insufficient, which is specifically manifested by its low suspension height. At this time, the superconducting material body 8 rotates to the second detection plate 5 with the electromagnet 7, and it will contact the second marking component on the second detection plate 5, and be attached with an unqualified mark, and then discharged from the second outlet 104; Step S5: the electromagnet 7 rotates again to the bottom of the loading assembly 2, and steps S1 to S4 are repeated to carry out the next round of testing of the new superconducting material body 8.

[0039] Working principle of the present invention: The above embodiment of the present invention provides a superconducting material detection device and a detection method thereof. When the electromagnet 7 rotates to the cooling component 3, the controller turns on the electromagnet 7. At this time, the superconducting material body 8 is located in the magnetic field generated by the electromagnet 7, and the temperature of the superconducting material body 8 will drop below the critical temperature under the action of the cooling component 3. At this time, the resistance of the superconducting material body 8 suddenly disappears and enters a zero resistance state. At this time, the magnetic flux lines inside the superconducting material body 8 are repelled, generating a reverse magnetic field, which offsets the original magnetic field to form a repulsive force, thereby causing the superconducting material body 8 to be magnetically suspended. At this time, the superconducting The material body 8 will move synchronously with the electromagnet 7. If the superconducting material body 8 is qualified, it is specifically manifested in that the height of the superconducting material body 8 is high enough to contact the first marking component on the first inspection plate 4, and is attached with a qualified mark, and then is discharged from the first outlet 103. If the superconducting material body 8 is unqualified, it means that its anti-magnetism is insufficient, then the suspension height of the superconducting material body 8 is low, and it will pass under the first inspection plate 4, and then come to the second inspection plate 5, and contact the second marking component on the second inspection plate 5, and be attached with an unqualified mark, and then be discharged from the second outlet 104.

[0040] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
