Description

Technical Field

[0001] This utility model relates to the field of superconducting technology, and in particular to a high-temperature superconducting tape wrapping and detection system. Background Technology

[0002] Insulation wrapping of high-temperature superconducting tapes is a crucial step in superconducting applications. The wrapping effect directly impacts the electrical performance, mechanical stability, and reliability of superconducting devices (such as superconducting magnets and cables). Therefore, high-temperature superconducting tape insulation wrapping machines are among the most important pieces of equipment in superconducting applications. High-temperature superconducting tape wrapping requires overlapping, with appropriate overlap distances between insulation layers; otherwise, uneven thickness will occur in the wrapped superconducting tape. Considering the relatively low critical tensile stress of superconducting tapes, and the fact that this critical tensile stress varies depending on the type of superconducting tape, the tension of the tensioning motor must be adjustable to prevent excessive tension that could lead to tape breakage. During the wrapping process, the superconducting tape and insulation tape must be tightly compressed to prevent air bubbles from forming, as this will affect the wrapping effect, resulting in poor insulation and potentially causing accidents in superconducting environments.

[0003] Currently available insulation wrapping machines only offer adjustable compression or tension, lacking automated quantitative testing of the insulation effect after superconducting tape wrapping. Furthermore, the surface cleanliness of the high-temperature superconducting tape is crucial to the wrapping effect. During processing, storage, and transportation, high-temperature superconducting tapes inevitably accumulate contaminants such as dirt, dust, and metal shavings. Directly wrapping the tape under these conditions will inevitably result in loose wrapping between the superconducting tape and the insulation tape, leading to numerous air bubbles and negatively impacting the insulation wrapping effect. Moreover, evaluating the insulation wrapping effect is an integral part of achieving high-quality automated insulation wrapping of superconducting tapes. Therefore, providing a system capable of automated cleaning, wrapping, and testing of insulation tape for high-temperature superconducting tapes is essential to ensuring the insulation quality of superconducting tapes.

This system can effectively remove contaminants such as dirt, dust, and metal shavings from the surface of the tape, perform pretreatment on the high-temperature superconducting tape before wrapping, ensure the insulation wrapping effect, and detect the overlap distance of the insulation tape. This enables quantitative detection of the insulation effect after the superconducting tape is wrapped, which is beneficial to improving the wrapping effect.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0010] In some embodiments, the pay-off device includes a pay-off reel and a first servo motor that drives the pay-off reel to rotate. The pay-off reel is used to carry a superconducting tape roll. When the first servo motor drives the pay-off reel to rotate, the pay-off reel can output the superconducting tape.

[0011] In some embodiments, the take-up device includes a take-up reel and a second servo motor for driving the take-up reel to rotate, the take-up reel being used to retrieve the superconducting tape wrapped with the insulating tape.

[0012] In some embodiments, the high-temperature superconducting tape wrapping and inspection system further includes a first guide wheel assembly, which is disposed between the wire feeding device and the cleaning device. The first guide wheel assembly includes a first guide wheel that abuts against two opposing surfaces of the superconducting tape.

In some embodiments, the traction device includes rollers that abut against two oppositely arranged sides of the superconducting tape wrapped with the insulating tape, and at least one of the rollers is provided with a pressure sensor.

[0015] The beneficial effects of this high-temperature superconducting tape wrapping and detection system are as follows: In actual operation, the superconducting tape is first installed on the pay-off device. The tape is then cleaned manually by a cleaning device. Insulating tape (such as polyimide film) is wrapped at the wrapping device, and a first compression is achieved by a pressing device.

A visual recognition device identifies and calculates the overlap distance of the automatically wrapped insulating tape, and finally, the tape is retrieved by a take-up device. Throughout the process, two compression processes ensure that the superconducting tape and the insulating tape are properly compressed. Before wrapping, the surface of the superconducting tape is cleaned to ensure good insulation without air bubbles.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0021] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0023] This utility model discloses a high-temperature superconducting tape wrapping and testing system, referencing... Figure 1 As shown, the high-temperature superconducting tape wrapping and inspection system includes a wire feeding device, a cleaning device, a wrapping device 8, a clamping device 9, a traction device 10, a meter counting device, a visual recognition device 13, and a take-up device arranged sequentially along the output direction of the superconducting tape. The wire feeding device outputs the superconducting tape, the cleaning device cleans the superconducting tape, the wrapping device 8 wraps the insulating tape around the superconducting tape, the clamping device 9 clamps the insulating tape and the superconducting tape, the traction device 10 pulls and clamps the superconducting tape wrapped with the insulating tape, the meter counting device records the length of the superconducting tape wrapped with the insulating tape, the visual recognition device 13 detects the wrapping quality of the superconducting tape, and the take-up device retrieves the superconducting tape wrapped with the insulating tape.

[0024] Understandably, in actual operation, the superconducting tape is first installed on the pay-off device. The tape is then manually moved through a cleaning device to clean it. Insulating tape (such as polyimide film) is wrapped at the wrapping device 8, where it is installed. The tape undergoes a first compression process via the pressing device 9, improving the wrapping effect of the insulating tape and the superconducting tape. Subsequently, the traction device 10 and the meter counting device assist in the tape movement and perform a second compression and meter counting function. The traction device 10 performs secondary compression of the superconducting tape wrapped with insulating tape and pulls it towards the take-up device. The meter counting device facilitates real-time monitoring of the length of the wrapped superconducting tape. The visual recognition device 13 performs pattern recognition and calculation on the stacking distance of the automatically wrapped insulating tape and can also detect the wrapping quality of the superconducting tape, such as checking for defects like air bubbles. Finally, the take-up device retrieves the tape. Throughout the entire process, two compression processes ensure that the superconducting tape and the insulating tape are properly compressed. Before wrapping, the surface of the superconducting tape is cleaned to ensure good insulation without the formation of air bubbles. The visual recognition device 13 can perform pattern recognition and calculation on the stacking distance of the insulating tape after automatic wrapping, and at the same time provide feedback signals to the control system of the wrapping device 8. Based on the calculation results, it decides whether to issue a warning signal, thus realizing the quantitative detection of the insulation effect of the superconducting tape after wrapping.

[0025] It should be further noted that the high-temperature superconducting tape winding and inspection system also includes a control device 11, which is a computer. The control device 11 is electrically connected to the pay-off device, traction device 10, meter counting device, visual recognition device 13, and take-up device, and controls the working status of these devices or records relevant parameters. Furthermore, the specific structure of the winding device 8 is existing technology, and there is no need to limit its specific structure here. The visual recognition device 13 may include a CCD camera and corresponding image recognition software. The specific structure of the visual recognition device 13 can be selected according to actual needs, and there is no need to limit its type here.

[0026] refer to Figure 1 As shown, the cleaning device includes an alcohol cleaning mechanism 5, a felt cleaning mechanism 6, and a nitrogen drying mechanism 7 arranged along the output direction of the superconducting tape. It can be understood that during the transportation of the superconducting tape, the first cleaning is performed by the alcohol cleaning mechanism 5, followed by a second cleaning by the felt cleaning mechanism 6, and finally drying by the nitrogen drying mechanism 7. This process effectively removes contaminants from the superconducting tape and ensures that the cleaned tape enters the winding device 8 dry for insulating tape winding, thereby guaranteeing the effective winding of the superconducting tape and the insulating tape, resulting in good insulation performance without bubble formation.

[0027] Optionally, the alcohol cleaning mechanism 5 includes an alcohol container, an upper cover, a lower cover, and a lint-free cloth. The alcohol container holds alcohol and has an injection pipe and a level indicator. The upper and lower covers are installed in the alcohol container. Part of the lint-free cloth is immersed in the alcohol, and the other part connects to the upper and lower covers, respectively abutting against two opposite surfaces of the superconducting tape. Understandably, during the actual cleaning process, the alcohol is transferred to the lower cover through the capillary effect of the lint-free cloth, working in conjunction with the lint-free cloth placed on the upper cover to clean both sides of the superconducting tape as it passes through.

[0028] Alternatively, the injection pipe has a liquid level display, which allows for easy monitoring of the alcohol usage and timely replenishment.

[0029] Alternatively, the upper cover is provided with a first locking handle. During the cleaning process, a certain clamping force can be applied through the first locking handle to press the superconducting tape onto the lint-free cloth installed on the lower cover, thereby improving the cleaning effect.

[0030] Alternatively, the lower cover plate is provided with a height-adjustable first extension rod. The first extension rod, together with the first locking handle, can easily adjust the vertical height of the device, so that the superconducting tape is always on the same plane during cleaning and wrapping, ensuring the wrapping effect.

[0031] Optionally, the felt cleaning mechanism 6 includes an upper pressure plate, a lower pressure plate, and a dust-free felt. The upper and lower pressure plates are spaced apart, and the dust-free felt is installed on the surfaces of the upper and lower pressure plates facing each other, and abuts against the two opposite surfaces of the superconducting tape. It is understood that in the actual cleaning process, the dust-free felt effectively cleans both the upper and lower surfaces of the superconducting tape as it passes through. Cleaning during the tape's movement improves work efficiency and ensures effective cleaning.

[0032] Alternatively, a second locking handle is provided on the upper pressure plate. During the cleaning process, a certain clamping force can be applied through the second locking handle to press the superconducting tape onto the lint-free cloth installed on the lower pressure plate, thereby improving the cleaning effect.

[0033] Alternatively, the lower pressure plate is provided with a second extension rod with adjustable height. The second extension rod, together with the second locking handle, can easily adjust the vertical height of the device, so that the superconducting tape is always on the same plane during cleaning and wrapping, ensuring the wrapping effect.

[0034] refer to Figure 1As shown, the pay-off device includes a pay-off reel 1 and a first servo motor 2 that drives the pay-off reel 1 to rotate. The pay-off reel 1 carries the superconducting tape roll. When the first servo motor 2 drives the pay-off reel 1 to rotate, the pay-off reel 1 can output the superconducting tape. It can be understood that in actual operation, by driving the pay-off reel 1 to rotate via the first servo motor 2 and adjusting the rotation speed of the first servo motor 2, the tension of the superconducting tape during transport can be adjusted, preventing excessive tension from causing breakage and failure.

[0035] refer to Figure 1 As shown, the take-up device includes a take-up reel 14 and a second servo motor 15 that drives the take-up reel 14 to rotate. The take-up reel 14 is used to wind the superconducting tape wrapped with insulating tape. It can be understood that in actual operation, by driving the take-up reel 14 to rotate via the second servo motor 15, the rotation speed of the second servo motor 15 can be adjusted to regulate the tension of the superconducting tape during the winding process, preventing excessive tension from causing breakage and failure.

[0036] refer to Figure 1 As shown, the high-temperature superconducting tape winding and inspection system also includes a first guide wheel group 4. The first guide wheel group 4 is located between the pay-off device and the cleaning device. The first guide wheel group 4 includes first guide wheels that abut against two opposing surfaces of the superconducting tape. It can be understood that after the superconducting tape is output from the pay-off reel 1, it enters the first guide wheel group 4. The function of the guide wheels in the first guide wheel group 4 is to guide, adjust, and constrain the movement direction of the superconducting tape, ensuring that the superconducting tape maintains tension and runs stably along a predetermined path. Simultaneously, it can distribute the load and reduce single-point stress, thereby enabling the superconducting tape to enter the cleaning device smoothly, thus improving the cleaning effect of the superconducting tape.

[0037] refer to Figure 1 As shown, the high-temperature superconducting tape wrapping and inspection system also includes a second guide wheel assembly 12. The second guide wheel assembly 12 is located between the vision recognition device 13 and the take-up device. The second guide wheel assembly 12 includes second guide wheels that abut against two opposing surfaces of the superconducting tape wrapped with insulating tape. It can be understood that after the superconducting tape wrapped with insulating tape is output from the vision recognition device 13, it enters the second guide wheel assembly 12. The function of the guide wheels in the second guide wheel assembly 12 is to guide, adjust, and constrain the movement direction of the superconducting tape wrapped with insulating tape, ensuring that the superconducting tape wrapped with insulating tape maintains tension and runs stably along a predetermined path. Simultaneously, it can distribute the load and reduce single-point stress. Through the guidance and re-pressuring of the second guide wheel assembly 12, the superconducting tape with insulating tape can smoothly enter the pay-off reel 1 for winding, thereby improving the wrapping of the superconducting tape and insulating tape, resulting in better insulation performance.

[0038] refer to Figure 1As shown, the high-temperature superconducting tape winding and inspection system also includes a base 16 and a worktable 3 mounted on the base 16. The cleaning device, winding device 8, clamping device 9, traction device 10, meter counting device, and visual recognition device 13 are all mounted on the worktable 3. The wire feeding device and wire take-up device are mounted on the base 16. The bottom of the base 16 is equipped with omnidirectional casters. Thus, by mounting the cleaning device, winding device 8, clamping device 9, traction device 10, meter counting device, and visual recognition device 13 on the worktable 3, and the wire feeding device, wire take-up device, and worktable 3 on the base 16, the entire high-temperature superconducting tape winding and inspection system is integrated into a single unit by the base 16. The overall structure and principle are simple yet feature-rich, operation is easy and convenient, and the appearance is aesthetically pleasing and lightweight, which helps improve user satisfaction. Optionally, the base 16 is composed of high-strength aluminum profiles.

[0039] In some embodiments, the traction device 10 includes rollers abutting against two opposing sides of the superconducting tape wrapped with insulating tape, and at least one roller is equipped with a pressure sensor. It is understood that when the traction device 10 performs secondary compression on the superconducting tape wrapped with insulating tape, the pressure sensor can detect the pressure on the superconducting tape wrapped with insulating tape, preventing the superconducting tape wrapped with insulating tape from breaking due to excessive pressure.

[0040] The advantages of the high-temperature superconducting tape wrapping and detection system in this embodiment are as follows:

[0041] First, the tension at both ends of the take-up and release line is continuously adjustable through the first servo motor 2 and the second servo motor 15, so as to avoid the superconducting tape from breaking due to excessive tension.

[0042] Secondly, during the wrapping process, the superconducting tape and the insulating tape are pressed together by the rollers of the traction device 10. The rollers are equipped with tension sensors to monitor the pressing force in real time to prevent the superconducting tape from being deformed and failing due to excessive pressure.

[0043] Third, a cleaning device is installed before the high-temperature superconducting tape is wrapped, which can effectively remove contaminants such as dirt, dust and metal shavings from the surface of the tape, and perform pretreatment of the high-temperature superconducting tape before wrapping to ensure the insulation wrapping effect.

[0044] Fourth, a visual recognition device 13 is installed to detect the overlapping distance of the insulating tape, realizing the quantitative detection of the insulation effect after the superconducting tape is wrapped.
