Description

Technical Field

[0001] This invention relates to the field of superconducting wire technology, and in particular to a device for wrapping the insulation layer of superconducting wire. Background Technology

[0002] Superconductors are superconductors that possess both absolute zero resistance and perfect diamagnetism below a certain temperature. They are widely used in large-scale scientific research equipment such as nuclear magnetic resonance imaging (MRI), high-frequency nuclear magnetic resonance spectrometers (NMR), high magnetic field devices, mass spectrometers, and particle accelerators. After the superconductor is fabricated, an insulating layer needs to be applied to its exterior. Currently, the insulating layer of superconductors used in liquid helium magnets is prepared by coating, but the enameling process requires significant investment in factory height and equipment, has a long processing time, and stringent environmental requirements. Furthermore, defects such as cracks, paint peeling, paint nodules, and uneven thickness are prone to occur in the wire's R-coating, affecting the insulation performance of the superconductor.

[0003] With the improvement of cable wrapping technology and the reduction of PI film costs, wrapping insulation for superconducting wires has become a possibility. However, existing superconducting wire wrapping devices generate turbulence when the wrapping head rotates at high speed. The airflow interferes with the thin wrapping tape, leading to unstable tension and insufficient dimensional accuracy. It also easily causes the insulation tape to shift, resulting in unstable wrapping pitch and affecting wrapping efficiency and accuracy. Furthermore, after wrapping and winding into a roll for sintering, gaps can easily appear between the insulation tapes, affecting the insulation performance of the superconducting wire.

[0004] Based on the above-mentioned technical problems, this application proposes a device for wrapping the insulation layer of superconducting wires. Summary of the Invention

[0006] Furthermore, the wrapping head includes a hollow main shaft, which is rotatably mounted on the frame via bearings. The end of the hollow main shaft away from the sintering mechanism is connected to the drive motor via a transmission assembly. A wrapping turntable is fixed to the end of the hollow main shaft near the sintering mechanism, and a guide frame is mounted on the wrapping turntable, with guide wheels mounted on the guide frame.

[0007] Furthermore, a connecting sleeve is provided at the end of the extension arm away from the hollow tube, and a limit sleeve is detachably installed inside the connecting sleeve; there are two windproof plates, which are arranged symmetrically about the center of the connecting sleeve.

[0008] Furthermore, a clamping mechanism is installed between the wrapping mechanism and the sintering mechanism. The clamping mechanism includes a clamping bracket with two clamping wheels mounted on it. The two clamping wheels are distributed vertically, and the superconducting wire passes between the two clamping wheels.

[0009] Furthermore, the moving assembly includes an X-axis transverse moving assembly and a Y-axis transverse moving assembly. The Y-axis transverse moving assembly is mounted on the X-axis transverse moving assembly. The connection surface between the furnace body and the furnace cover is vertical. The furnace body of the sintering furnace is mounted on the Y-axis transverse moving assembly.

[0010] Furthermore, a telescopic component is provided between the furnace body and the furnace cover, which is used to drive the automatic opening and closing of the furnace cover.

[0011] Furthermore, a cleaning mechanism is provided upstream of the wrapping mechanism. The cleaning mechanism includes an inner tube, an outer tube, and two annular end plates connecting the ends of the inner tube and the outer tube. A first air inlet is provided on the outer tube, which is connected to a steam generator. The superconducting wire is inserted in the inner tube, and several air blowing holes are provided on the inner tube.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] like Figure 1 The superconducting wire insulation wrapping device shown includes an unwinding mechanism (not shown), a cleaning mechanism 2, a wrapping mechanism 3, a pressing mechanism 4, a sintering mechanism 5, and a winding mechanism (not shown). The superconducting wire 1 is conveyed from left to right under the drive of the unwinding and winding mechanisms. The cleaning mechanism 2, the wrapping mechanism 3, the pressing mechanism 4, and the sintering mechanism 5 are sequentially installed between the unwinding and winding mechanisms from left to right. The structure and principle of the unwinding and winding mechanisms are existing technologies and will not be described in detail here.

[0021] like Figure 2 As shown, the cleaning mechanism 2 includes an inner tube 21, an outer tube 22, and two annular end plates 23. The two end plates 23 are respectively installed at both ends of the inner tube 21 and the outer tube 22. The inner edge of the end plate 23 is connected to the end of the inner tube 21, and the outer edge of the end plate 23 is connected to the end of the outer tube 22, so that the outer wall of the inner tube 21, the inner wall of the outer tube 22, and the inner walls of the two end plates 23 form a closed space.

[0022] like Figure 2 As shown, the inner tube 21 has several air blowing holes 211, which are evenly distributed along the circumference of the inner tube 21, and the inner ends of the air blowing holes 211 are inclined upstream in the conveying direction of the superconducting wire 1. An annular partition 24 is installed between the two end plates 23, which divides the cleaning mechanism 2 into a cleaning zone on the left and a drying zone on the right, and the length of the cleaning zone is greater than the length of the drying zone. The outer tube 22 of the cleaning zone has a first air inlet 221, which is connected to a steam generator through a pipe to supply high-pressure steam to the cleaning zone. The outer tube 22 of the drying zone has a second air inlet 222, which is connected to an air compressor to supply high-pressure air to the drying zone.

[0023] During use, the superconducting wire 1 passes sequentially through the cleaning zone and the drying zone. When the superconducting wire 1 passes through the cleaning zone, high-pressure steam is blown at an angle towards it, removing oil and dirt. When the superconducting wire 1 passes through the drying zone, high-pressure air is blown at an angle towards its surface, drying the cleaned wire. Simultaneously, the introduction of high-pressure air forces the cleaned steam to flow out to the left, preventing secondary contamination of the superconducting wire 1 by any blown-off oil.

[0024] In a preferred embodiment of this application, sealing plates 25 are detachably installed on the inner rings of both end plates 23 by bolts. A through hole for mates with the superconducting wire 1 is provided in the center of each sealing plate 25, and the through hole on the right sealing plate 25 is smaller than that on the left sealing plate 25, thereby reducing steam leakage in the inner pipe 21, increasing the steam discharge pressure, and thus improving the discharge efficiency of oily steam after cleaning. A drain port 26 is also provided at the bottom of the outer pipe 22 in the cleaning area, and a valve is installed at the drain port 26 for discharging condensate.

[0025] like Figures 3-6 As shown, the wrapping mechanism 3 includes a frame 31, a wrapping head 32, a drive motor 33, and a magnetic powder clutch 34. The frame 31 is a rectangular shell made of spliced ​​plates. The wrapping head 32 is rotatably mounted on the frame 31. The drive motor 33 is connected to the wrapping head 32 for driving the wrapping head 32 to rotate.

[0026] like Figure 5 , Figure 6As shown, the winding head 32 includes a hollow main shaft 321, which is rotatably mounted on a frame 31 via bearings. Both ends of the hollow main shaft 321 extend out of the frame 31. Two main drive wheel pairs 322 are mounted at the rear end of the hollow main shaft 321. One main drive wheel pair 322 is connected to the drive motor 33, and the other main drive wheel pair 322 is connected to the input shaft of the magnetic powder clutch 34. A winding turntable 323 is mounted at the front end of the hollow main shaft 322. A guide frame 324 is mounted on the winding turntable 323, and two guide wheels 325 are mounted on the guide frame 324. When the drive motor 33 rotates, it drives the hollow main shaft 321 to rotate via the main drive wheel pairs 322, which in turn drives the winding turntable 323 and the guide frame 324 to rotate.

[0027] like Figures 3-6 As shown, a hollow tube 326 is rotatably mounted inside the hollow spindle 321 via bearings. The rear end of the hollow tube 326 extends beyond the rear end of the hollow spindle 321, and the rear end of the hollow tube 326 is connected to the output shaft of the magnetic powder clutch 34 via a secondary transmission wheel pair 327. The front end of the hollow tube 326 extends beyond the front end of the hollow spindle 321, and a material tray 328 is mounted on the front end of the hollow tube 326. An insulating tape roll 36 is mounted on the material tray 328, and the insulating tape roll 36 is coaxially arranged with the hollow tube 326. The front end of the hollow tube 326 extends beyond the insulating tape roll 36 and is equipped with an extension arm 37. A connecting sleeve 371 is mounted at the end of the extension arm 37. A limit sleeve 372 is detachably mounted inside the connecting sleeve 371 via bolts. The superconducting wire 1 is inserted inside the hollow tube 326 and passes through the inner hole of the limit sleeve 372. If the superconducting wire 1 is a round wire, the inner diameter of the limiting sleeve 372 is equal to the outer diameter of the superconducting wire 1; if the superconducting wire 1 is a flat wire, the inner diameter of the limiting sleeve 372 is equal to the widest part of the superconducting wire 1. The limiting sleeve 372 is used to limit the superconducting wire 1 to prevent the tension of the insulating tape 361 during wrapping from causing the superconducting wire 1 to deviate and affecting the wrapping quality of the superconducting wire 1.

[0028] like Figures 3-6 As shown, when the drive motor 33 rotates, it drives the hollow main shaft 321 to rotate via the main drive wheel pair 322, which in turn drives the wrapping turntable 323 and the guide frame 324 to rotate. Simultaneously, the main drive wheel pair 322 drives the hollow tube 326 and the material tray 328 to rotate synchronously via the magnetic powder clutch 34 and the auxiliary drive wheel pair 327, causing the insulating tape 361 to wrap around the superconducting wire 1. Encoders 35 are installed at the output ends of both the drive motor 33 and the magnetic powder clutch 34.

[0029] During normal operation, the insulating tape 361 pulls the hollow tube 326 to rotate, causing the hollow tube 326 and the hollow spindle 321 to rotate at different speeds. However, when a tape breakage occurs, since there is no insulating tape 361 pulling on it, the hollow tube 326 and the hollow spindle 321 will rotate at the same speed. By monitoring the speeds of the hollow tube 326 and the hollow spindle 321 with two encoders 35 respectively, tape breaks can be detected promptly, reducing the time required for manual repairs.

[0030] like Figure 3 , Figure 4 As shown, two wind deflectors 38 are also installed on the wrapping head 32. One end of the wind deflector 38 is fixedly connected to the guide frame 324, and the other end of the wind deflector 38 is connected to the connecting sleeve 371 of the extension arm 37. The wind deflector 38 covers at least the portion of the insulating tape 361 between the last guide wheel 325 and the superconducting wire 1, and the wind deflector 38 is located in front of the insulating tape 361 in the wrapping direction to prevent the insulating tape 361 from directly cutting the airflow and causing deviation during rotation. At the same time, the installation of the wind deflector 38 can also increase the stability of the extension arm 37 and improve the wrapping quality of the superconducting wire 1.

[0031] There are two windproof plates 38, which are arranged symmetrically around the center of the connecting sleeve 371 to ensure that the center of gravity of the wrapping head 32 is at the center of rotation, thus ensuring the stability of the rotation around the wrapping head 32.

[0032] In a preferred embodiment of this application, a belt traction machine is also installed between the clamping mechanism 4 and the sintering mechanism 5. The belt traction machine is used to pull the superconducting wire 1 to ensure the stability of the tension of the superconducting wire 1 and to prevent the superconducting wire 1 from shaking. The structure and principle of the belt traction mechanism are existing technologies and will not be described in detail here.

[0033] like Figure 1 , Figure 7 As shown, a clamping mechanism 4 is installed between the wrapping mechanism 3 and the sintering mechanism 5. The clamping mechanism 4 includes a clamping bracket 41, on which two clamping rollers 42 are installed. The two clamping rollers 42 are distributed vertically, and annular clamping grooves are respectively opened on the circumference of the two clamping rollers 42. The cross-section of the two clamping grooves matches the cross-section of the superconducting wire 1. The wrapped superconducting wire 1 passes through the clamping groove between the two clamping rollers 42 to clamp the insulating tape 361 and expel the air between the insulating tape 361 and the superconducting wire 1.

[0034] like Figure 1 , Figure 8As shown, the sintering mechanism 5 includes a sintering furnace 51 and a moving assembly 52, with the sintering furnace 51 mounted on the moving assembly 52. ​​The moving assembly 52 includes an X-axis transverse moving assembly 521 and a Y-axis transverse moving assembly 522. The X-axis transverse moving assembly 521 is mounted parallel to the conveying direction of the superconducting wire 1, and the Y-axis transverse moving assembly 522 is mounted perpendicular to the output direction of the superconducting wire 1 on the X-axis transverse moving assembly 521. The X-axis transverse moving assembly 521 and the Y-axis transverse moving assembly 522 can be linear modules of lead screws or linear modules of pneumatic / hydraulic cylinders.

[0035] The sintering furnace 51 includes a furnace body 511 and a furnace cover 512. The furnace body 511 is mounted on a Y-axis transverse moving assembly 522, and the furnace cover 512 is mounted on the side of the furnace body 511, such that the connection surface between the furnace body 511 and the furnace cover 512 is parallel to the vertical plane of the X-axis transverse moving assembly 521. A sintering channel parallel to the axis of the superconducting wire 1 is formed at the connection surface between the furnace body 511 and the furnace cover 512, and the wrapped superconducting wire 1 is inserted into the sintering channel. Electric heaters are installed on both the side of the furnace body 511 and the side of the furnace cover 512 to achieve uniform heating of the superconducting wire 1. A telescopic component (not shown) is installed between the furnace body 511 and the furnace cover 512, which is used to drive the automatic opening and closing of the furnace cover 512.

[0036] In the event of a malfunction and shutdown during operation, the sintering furnace 51 stops heating, the telescopic component drives the furnace cover 512 to open automatically, and then moves backward under the drive of the Y-axis transverse component 521 to prevent overheating of the superconducting wire 1 and to provide space for repairs. Upon restarting, the Y-axis transverse component 521 resets the sintering furnace 51, and simultaneously moves it downstream in the superconducting wire 1 conveying direction to reheat any over-displaced superconducting wire 1, preventing incomplete sintering that could affect the wrapping quality of the superconducting wire 1.

[0037] A cooling mechanism is installed on the rear side of the sintering mechanism 5. The structure of the cooling mechanism is the same as that of the drying zone of the cleaning mechanism 2. When the sintered superconducting wire passes through the cooling mechanism, high-pressure air is blown onto the surface of the superconducting wire to cool it down.

[0038] Preferably, a first detection mechanism is installed on the rear side of the wrapping mechanism 3. The first detection mechanism is used to detect the wrapping quality of the wrapping mechanism 3 and promptly detect defects such as wrapping pitch and wrapping size. A second detection mechanism is installed on the rear side of the sintering mechanism. The second detection mechanism is used to detect the sintering quality of the sintering mechanism and promptly detect defects such as sintering size and insulation performance. The structure and principle of the detection mechanisms are existing technologies and will not be described in detail here.

[0039] The technical solutions provided in this application have at least the following technical effects or advantages: 1. By installing a sintering mechanism downstream of the wrapping mechanism, the wrapped superconducting wire can be sintered directly. This can avoid repeated winding, improve the production efficiency of superconducting wire, and avoid deformation of the insulating tape caused by winding, thus improving the insulation performance of superconducting wire. 2. By setting up a visual inspection mechanism and a movable sintering mechanism, the sintering mechanism can be removed from the superconducting wire when a defect is detected, thus avoiding overburning of the superconducting wire. It also facilitates online repair of the insulation layer of the superconducting wire, avoiding the time loss of individual repairs and secondary damage caused by multiple winding and unwinding. 3. By setting a movable sintering mechanism, the sintering mechanism can be moved upstream of the superconducting wire to re-sinter the superconducting wire, avoiding incomplete sintering caused by machine shutdown and ensuring the quality of the superconducting wire. 4. Using a steam cleaning device to clean superconducting wires can avoid the black spots and adhesive residues caused by traditional combustion to remove oil stains, thus improving the cleaning effect and reducing pollution and energy consumption; 5. By installing a windproof plate between the guide frame and the extension arm, the airflow generated by the high-speed rotation of the wrapping head can be avoided from affecting the insulating tape. On the other hand, the stability of the extension arm can be improved, thereby improving the wrapping accuracy and ensuring the quality of the superconducting tape.
