TECHNICAL FIELD

[0001] The present application relates to the technical field of superconducting tape measurement, in particular to a superconducting tape detection device. BACKGROUND

[0002] Critical current is an important physical parameter of superconducting material, and mastering the current-carrying capacity of superconducting tape under different temperature and magnetic field conditions is a factor that must be considered for various applications. The commonly used detection methods include electrical measurement and magnetic measurement.

[0003] Usually when measuring, after finding the abnormal point of the superconducting tape, manual labeling of the abnormal point of the superconducting tape is often needed, which not only may cause inaccurate labeling, but also is tedious and inefficient, resulting in low detection efficiency and accuracy. CONTENT OF THE INVENTION

[0004] Therefore, the present application provides a superconducting tape detection device to solve the technical problem of low efficiency and accuracy in the prior art.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] A superconducting tape detection device comprises a cooling tank arranged in a mounting seat, a first take-up and pay-off module and a second take-up and pay-off module independently arranged on both sides of the mounting seat, a first reel in the first take-up and pay-off module, and a second reel in the second take-up and pay-off module, a wiring assembly arranged on the mounting seat for mounting and driving the superconducting tape between the first reel and the second reel, the wiring assembly comprising an immersion part capable of being immersed in the cooling tank to guide the superconducting tape to enter and exit the cooling tank, a detection device mounted on the immersion part for detecting the superconducting tape, and an abnormal point marking device arranged at the superconducting tape between the first reel and the immersion part and / or at the superconducting tape between the second reel and the immersion part for marking abnormal points in the superconducting tape detected by the detection device.

[0007] In an embodiment, the superconducting tape detection device further comprises an appearance detection device arranged behind the abnormal point marking device along the direction of the superconducting tape.

[0008] In an embodiment, the wiring assembly comprises a plurality of guide wheels for guiding the superconducting tape to form a horizontal wiring section between the first reel and the immersion part and between the second reel and the immersion part, and the abnormal point marking device is mounted at the horizontal wiring section.

[0009] In an embodiment, the superconducting tape detection device further comprises a height adjusting device connected with the cooling tank, for driving the cooling tank to move vertically to switch the state of the immersion part between being immersed in the cooling tank and being separated from the cooling tank.

[0010] In an embodiment, the height adjusting device comprises an electric lifting mechanism or a hydraulic lifting mechanism.

[0011] In an embodiment, the immersion part has a pre-detection wiring section and a post-detection wiring section on both sides, and a drying device is arranged at the post-detection wiring section.

[0012] In an embodiment, the post-detection wiring section has a vertical section, and the drying device is arranged at the vertical section.

[0013] In an embodiment, the mounting seat further has a superconducting tape length measuring device mounted thereon, for measuring the wiring length of the superconducting tape in the wiring assembly.

[0014] In an embodiment, the wiring assembly further comprises a tension control wheel movably connected with the mounting seat, and the mounting seat further has an adjusting assembly arranged thereon for driving the tension control wheel to move to adjust the winding tension of the superconducting tape.

[0015] In an embodiment, the first take-up and pay-off module further comprises a first rotation driving mechanism for driving the first reel to rotate forward or reverse; and the second take-up and pay-off module further comprises a second rotation driving mechanism for driving the second reel to rotate forward or reverse.

[0016] The present application has the following advantages due to the above technical solutions:

[0017] The first take-up and pay-off module and the second take-up and pay-off module are designed in a modular manner, which reduces the difficulty of processing, manufacturing and transportation, is more convenient for assembly, and is more conducive to later maintenance and upgrading. Meanwhile, the abnormal point marking device is arranged on the superconducting tape between the first reel and the immersion part and / or between the second reel and the immersion part. When the detection device detects that there is a quality problem in the superconducting tape, the control mechanism is fed back to control the abnormal point marking device to mark the problem point on the superconducting tape according to the movement speed of the superconducting tape. By automatically marking the abnormal point, the labor can be saved, and the marking efficiency and accuracy can be improved, thereby improving the detection accuracy.

[0018] When using this testing equipment to measure the critical current of superconducting tape, before wiring, the operator can manipulate the height adjustment device to lower the cooling tank, causing the immersion part to detach from the cooling tank. This switches the cooling tank to a state where it is detached from the cooling medium, allowing the operator to completely avoid the cooling tank during wiring and preventing interference from its overall structure. After the superconducting tape wiring is completed, the operator can manipulate the height adjustment device to raise the cooling tank, causing the immersion part to re-immerse itself in the cooling tank, thus switching the cooling tank to a state where it is immersed in the cooling medium. At this point, the initial preparation work for superconducting tape installation is complete. When wiring the superconducting tape, the operator can adjust the position of the liquid nitrogen cooling tank as needed, offering high flexibility. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] Unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," "third," "fourth," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

[0029] Reference Figs. 1 to 3As shown, the superconducting tape testing device involved in this application includes: a cooling tank 10, which is disposed in a mounting base; a first take-up and release module 20 and a second take-up and release module 30, which are independently distributed on both sides of the mounting base, wherein the first take-up and release module 20 has a first wire reel 21 and the second take-up and release module 30 has a second wire reel 31; and a wiring assembly 40, which is disposed on the mounting base and is used to install and drive the superconducting tape between the first wire reel 21 and the second wire reel 31. The device includes an immersion section 41, which is capable of being immersed in the cooling tank 10 to guide the superconducting tape into and out of the cooling tank 10; a detection device 50, installed in the immersion section 41, for detecting the superconducting tape; and an anomaly marking device 60, disposed on the superconducting tape between the first coil 21 and the immersion section 41, and / or disposed on the superconducting tape between the second coil 31 and the immersion section 41, for marking anomalies detected by the detection device 50 in the superconducting tape.

[0030] The cooling tank 10 can be filled with a cooling medium, which can be either liquid nitrogen or liquid helium.

[0031] The detection device 50 can employ a magnetic detection device, specifically comprising two excitation coils and a magnetic field detection device. The superconducting tape forms a horizontal trace segment in the immersion section 41, which serves as the detection segment. The two excitation coils are positioned at both ends of the detection end, and the magnetic field detection device is located in the middle of the detection end. Under low-temperature conditions with a cooling medium, the excitation coils are energized to generate a fixed magnetic field at the slits in the superconducting tape and the measurement slit. When the superconducting tape passes through the slits, a circular current is induced within the superconducting tape. Combined with the magnetic field detection device, this completes the detection of the critical current of the superconducting tape. This is a commonly used detection method and will not be elaborated further. Alternatively, the detection device 50 can also employ an electrical measurement method such as a four-lead detection device or a dual-bridge detection device.

[0032] The abnormal point marking device 60 can be a printing device, such as an inkjet valve; or it can be a transfer device, such as a transfer marking machine.

[0033] In one embodiment, the bottom of the testing device can be fitted with casters for movement and height adjustment, facilitating transportation and movement.

[0034] In this application, the first take-up and release module 20 and the second take-up and release module 30 adopt a modular design, which reduces the difficulty of processing, manufacturing and transportation, makes assembly easier, and facilitates later maintenance and upgrades. At the same time, the abnormal point marking device 60 is set on the superconducting tape between the first wire reel 21 and the immersion part 41, and / or set on the superconducting tape between the second wire reel 31 and the immersion part 41. When the detection device 50 detects a quality problem in the superconducting tape, it feeds back to the control mechanism. The control mechanism controls the abnormal point marking device 60 to mark the problem points on the superconducting tape according to the movement speed of the superconducting tape. By automatically marking abnormal points, manual labor can be saved, and the marking efficiency and accuracy can be improved, thereby improving the accuracy of detection.

[0035] In one embodiment, the superconducting tape testing equipment further includes a height adjustment device 80 connected to the cooling tank 10, used to drive the cooling tank 10 to move vertically, thereby switching the immersion state of the immersion part 41 in and out of the cooling tank 10. The height adjustment device 80 is connected to the cooling tank 10 and drives the cooling tank 10 to move vertically, thereby switching the immersion state of the immersion part 41 in the cooling medium and the state of being out of the cooling medium. When using the testing equipment to measure the critical current of the superconducting tape, the operator only needs to install the superconducting tape onto the wiring assembly 40 and complete the initial wiring of the superconducting tape. Before wiring, the operator can operate the height adjustment device 80 to drive the cooling tank 10 downward, causing the immersion part 41 to disengage from the cooling tank 10, thereby adjusting and switching the cooling tank 10 to the state of being out of the cooling medium. Therefore, during the wiring process, the operator can completely avoid the cooling tank 10, avoiding interference from the overall structure of the cooling tank 10 on the wiring operation. After the superconducting tape is threaded and installed, the operator uses the height adjustment device 80 to move the cooling tank 10 upwards, causing the immersion part 41 to re-immerse itself in the cooling tank 10. This switches the cooling tank 10 to the state of immersion in the cooling medium, thus completing the initial preparation work for the superconducting tape installation of the testing equipment. The height adjustment device 80 not only facilitates the threading of the superconducting tape but also facilitates the addition and evacuation of liquid nitrogen.

[0036] In one embodiment, the height adjustment device 80 includes an electric lifting mechanism or a hydraulic lifting mechanism. Of course, the height adjustment device 80 can also be a manual lifting device. In this embodiment, the height adjustment device 80 uses an electric lifting mechanism as an example. The electric lifting mechanism includes an electric push rod, and the telescopic shaft of the electric push rod is connected to the cooling tank 10. When it is necessary to adjust the specific height of the cooling tank 10, the electric push rod can be operated to extend or retract for adjustment.

[0037] In one embodiment, the appearance inspection device 70 is positioned behind the anomaly marking device 60 along the direction of the superconducting tape. The appearance inspection device 70 inspects the appearance quality of the superconducting tape. When an anomaly is detected, it feeds back to the control mechanism. The control mechanism, based on the superconducting tape's movement speed, controls the anomaly marking device 60 to mark appearance anomaly points on the superconducting tape, thereby enabling simultaneous marking of both detection and appearance anomalies.

[0038] In this embodiment, the appearance inspection device 70 may include a camera to achieve visual inspection of the outer surface of the superconducting tape. The appearance inspection device 70 may include an optical detection sensor or an acoustic detection sensor to achieve detection of the outer surface of the superconducting tape.

[0039] Taking the appearance inspection device 70, which uses a camera, as an example, the camera can capture images of the superconducting tape along its routing path in real time. Workers can monitor the surface of the superconducting tape on a display screen in real time, facilitating the detection of surface defects. Furthermore, the images captured by the camera can be transmitted to a recognition device, which can then replace manual labor in detecting surface defects in the superconducting tape.

[0040] The wiring assembly 40 includes multiple guide rollers 42, which guide the superconducting tape to form horizontal wiring segments between the first reel 21 and the immersion portion 41, and between the second reel 31 and the immersion portion 41. The anomaly marking device 60 is installed at the horizontal wiring segments. Installing the anomaly marking device 60 at the horizontal segments makes it easier to adjust the marking angle of the anomaly marking device 60 to be perpendicular to the superconducting tape, so as to mark the anomalies on the surface of the superconducting tape more completely and clearly. In this embodiment, the appearance inspection device 70 uses a camera as an example. Installing the camera at the horizontal segments makes it easier to adjust the shooting angle of the camera to be perpendicular to the superconducting tape, so as to capture the surface of the superconducting tape more completely and clearly.

[0041] After the superconducting tape enters the cooling tank 10, its temperature decreases. When it exits the cooling tank 10, the surrounding water vapor condenses into condensate and adheres to the superconducting tape, affecting its subsequent use. In this embodiment, the immersion section 41 has pre-inspection routing sections and post-inspection routing sections on both sides. A drying device 43 is provided at the post-inspection routing section to heat and dry the superconducting tape after it has passed through the cooling tank 10, removing the condensate from the superconducting tape.

[0042] In order to minimize the impact of the cooling medium on the operation of the entire equipment and achieve better drying effect, the drying device 43 is set at the vertical section of the post-inspection wiring section.

[0043] In one embodiment, the first take-up and pay-off module 20 further includes a first rotary drive mechanism 22, which drives the first reel 21 to rotate forward or in reverse; the second take-up and pay-off module 30 further includes a second rotary drive mechanism 32, which drives the second reel 31 to rotate forward or in reverse. Through the forward or reverse rotation of the first rotary drive mechanism 22 and the second rotary drive mechanism 32, the pay-off reel can be used as a take-up reel, and the take-up reel can be used as a pay-off reel, achieving bidirectional use and facilitating repeated inspection of the strip.

[0044] In bidirectional use, the pre-inspection wiring segment and the post-inspection wiring segment can be interchanged. Therefore, two drying devices 43 can be installed, one on the pre-inspection wiring segment and the other on the post-inspection wiring segment.

[0045] In one embodiment, the wiring assembly 40 further includes a tension control wheel 45, which is movably connected to a mounting base. The mounting base is also provided with an adjustment assembly that drives the tension control wheel 45 to move in order to adjust the winding tension of the superconducting tape.

[0046] Specifically, in this embodiment, the adjustment component includes a stud, and the shaft of the tension control wheel 45 is vertically and movably connected to the mounting base. Simultaneously, the shaft is threadedly connected to the stud. By rotating the stud, the height of the shaft of the tension control wheel 45 can be adjusted, thereby achieving the effect of adjusting the tension of the superconducting tape winding. During the measurement process, the operator can observe the routing of the superconducting tape in the wiring assembly 40 and adjust the tension control wheel 45 as needed to regulate the tension of the superconducting tape. The tension control wheel 45 further improves the operational stability of this testing equipment.

[0047] In some embodiments, a superconducting tape length measuring device 44 is also provided on the mounting base for measuring the trace length of the superconducting tape in the wiring assembly 40. The superconducting tape length measuring device 44 may include a roller-type meter counter or an optical length sensor.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
