Description

Technical Field

[0001] This utility model relates to the technical field of superconducting coil winding, and in particular to a winding production line suitable for three-dimensional superconducting coils of stellarators. Background Technology

[0002] Superconducting coils are widely used in stellarators, superconducting magnets, and other fields. Taking the application in stellarators as an example, when winding a three-dimensional superconducting coil for a stellarator, the winding mold is usually fixed on a rotary table first. Then, the superconducting conductor is wound onto the winding mold after straightening, sandblasting, and other steps. During the winding process, the rotary table drives the winding mold to rotate and winds the superconducting conductor into the groove of the winding mold. However, during the winding process, the rotary table drives the winding mold to rotate, so the superconducting conductor may be offset or swing. After the superconducting conductor is offset or swings, it may cause poor winding quality of the three-dimensional superconducting coil for the stellarator, or even cause the coil winding to fail.

[0003] Therefore, during the winding process of the stellarator three-dimensional superconducting coil in the existing technology, the superconducting conductor may shift, swing, or twist, which may result in poor winding quality of the stellarator three-dimensional superconducting coil or even coil winding failure. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the winding process of the three-dimensional superconducting coil of the stellarator in the prior art, the superconducting conductor may shift, swing or twist, which may cause poor winding quality of the three-dimensional superconducting coil of the stellarator or even the failure of coil winding.

[0005] To solve the above-mentioned technical problems, the present invention discloses a winding production line for three-dimensional superconducting coils of stellarators. The winding production line includes a wire feeding device, a centering calibration device, a conductor straightening device, a sandblasting device, a follow-up support device, and a winding device.

[0006] The wire-laying device includes a wire-laying roller for winding and releasing the superconducting conductor. A centering calibration device is positioned downstream of the wire-laying device along the transport direction of the superconducting conductor; this device centers and calibrates the superconducting conductor released from the wire-laying roller. A conductor straightening device is positioned downstream of the centering calibration device along the transport direction of the superconducting conductor; this device straightens the calibrated superconducting conductor. A sandblasting device is positioned downstream of the conductor straightening device along the transport direction of the superconducting conductor; this device sandblasts the outer wall of the straightened superconducting conductor.

[0007] The follower support device is located downstream of the sandblasting device. The follower support device includes a movable follower, which is used for the superconducting conductor after sandblasting to bypass the sandblasting device, and the superconducting conductor can move synchronously with the follower.

[0008] The winding device includes a ring-shaped winding die that can rotate around a preset axis, and the winding die is used to wind a superconducting conductor wound from a follower of a follower support device to form a stellarator three-dimensional superconducting coil.

[0009] Using the above technical solution, after the superconducting conductor is released from the wire release device, it is sequentially transmitted to the centering calibration device for centering calibration, and then transmitted to the conductor straightening device for straightening. After straightening, it is sent to the sandblasting device to sandblast the outer wall of the superconducting conductor. After sandblasting, the superconducting conductor is wound on the winding mold of the winding device after passing through the follower, and finally wound to form the stellarator three-dimensional superconducting coil.

[0010] Furthermore, the movable follower in the servo support device provides dynamic support for the superconducting conductor. During the winding process, when the winding device drives the winding die to rotate, the superconducting conductor will be subjected to various forces, causing it to tend to deviate, oscillate, or twist. The follower can move synchronously with the movement of the superconducting conductor, adjusting the support position and angle of the wire in a timely manner, providing a stable guiding path for the wire, effectively suppressing the twisting of the superconducting conductor after deviation or oscillation, thereby improving the winding quality of the superconducting coil and reducing the risk of coil winding failure.

[0011] In addition, when the winding die rotates during the winding process, the superconducting conductor may shift left or right along its transmission direction. For example, when the superconducting conductor shifts to the left or swings during the winding process, the follower can move to the left with the superconducting conductor. When the superconducting conductor shifts to the right or swings during the winding process, the follower can move to the right with the superconducting conductor, providing stable support and guidance for the superconducting conductor.

[0012] More preferably, the winding device further includes a rotary table and a drive unit, with the winding die fixed to the rotary table. The drive unit is used to drive the rotary table to rotate, thereby causing the winding die fixed to the rotary table to rotate around a preset axis.

[0013] Using the above technical solution, the driving component drives the rotary table to rotate, and the winding mold fixed to the rotary table rotates around a preset axis. Then, the superconducting conductor is wound around the winding mold one turn at a time to form a stellarator three-dimensional superconducting coil.

[0014] The present invention also discloses a winding production line suitable for stellarator three-dimensional superconducting coils. The winding mold includes an annular support base, an inner side plate, and an outer side plate. The inner side plate and the outer side plate are spaced apart along the radial direction of the support base and are all fixed to the top of the support base. The top of the support base, the inner side plate, and the outer side plate together define an annular winding groove. A superconducting conductor is sequentially wound around the winding groove to form a stellarator three-dimensional superconducting coil. The outer peripheral surface of the inner side plate is used to adapt to the inner peripheral surface of the stellarator three-dimensional superconducting coil, and the inner peripheral surface of the outer side plate is used to adapt to the outer peripheral surface of the stellarator three-dimensional superconducting coil.

[0015] The present invention also discloses a winding production line suitable for stellarator three-dimensional superconducting coils. The conductor straightening device has a straightening channel for the superconducting conductor released by the pay-off roller to pass through, so as to straighten the superconducting conductor.

[0016] The centering calibration device is used for the superconducting conductor released by the pay-off roller to pass through, so that the superconducting conductor after passing through the centering calibration device enters the straightening channel with its transmission direction aligned with the entrance of the straightening channel.

[0017] Using the above technical solution, the superconducting conductor released from the pay-off roller undergoes a first calibration via a centering calibration device, and then enters a conductor straightening device for a second calibration.

[0018] Furthermore, the centering calibration device includes a horizontal calibration component and a vertical calibration component. The horizontal calibration component includes a plurality of rotatable horizontal calibration rollers spaced apart on both sides of the superconducting conductor in the horizontal direction, and the vertical calibration component includes a plurality of rotatable vertical calibration rollers spaced apart on both sides of the superconducting conductor in the vertical direction.

[0019] The conductor straightening device includes multiple active wheels and multiple passive wheels arranged alternately along the transmission direction of the superconducting conductor. A straightening channel is formed between the multiple active wheels and multiple passive wheels for the superconducting conductor to pass through. The conductor straightening device also includes an adjustment component, which can adjust the position of one or more of the multiple active wheels or multiple passive wheels in the height direction.

[0020] By adopting the above technical solution, the horizontal calibration component and the vertical calibration component can relatively confine the superconducting conductor to the center position, ensuring the accurate transmission of the superconducting conductor in the horizontal direction and avoiding the risk of the superconducting conductor deviating from the transmission path.

[0021] The conductor straightening device can eliminate the bending deformation of the superconducting conductor before winding, ensuring that the superconducting conductor has a certain straightness, laying the foundation for subsequent precise winding.

[0022] The sandblasting device includes a sandblasting machine and at least one cleaning auxiliary machine located on one side of the sandblasting machine. The sandblasting machine has a sandblasting chamber inside, and a sandblasting port is provided inside the sandblasting chamber. The sandblasting machine has an inlet and an outlet at both ends for superconducting conductors to pass through, and both the inlet and outlet are provided with seals. The cleaning auxiliary machine is a dust collector.

[0023] Using the above technical solution, the sandblasting device uses high-pressure airflow to spray abrasive onto the surface of the superconducting conductor, removing the surface oxide layer and forming a uniform rough texture, thus improving the surface friction and resin adhesion. The dust collector can clean the sandblasted superconducting conductor.

[0024] The present invention also discloses a winding production line suitable for three-dimensional superconducting coils of stellarators. The follower support device further includes a support frame, and the follower is movably mounted on the support frame. The follower can rotate relative to the support frame about a first axis and can move relative to the support frame in the direction of the first axis. The follower is provided with a wire groove for adapting to the superconducting conductor.

[0025] Using the above technical solution, the support frame provides structural support for the follower. The follower can rotate relative to the support frame around the first axis and can also move relative to the support frame along the direction of the first axis. Therefore, the follower has a high degree of freedom. When the superconducting conductor experiences a positional or angular shift, the follower can readjust the position of the wire by rotating and moving, always providing stable and accurate support and guidance for the superconducting conductor, effectively preventing problems such as wire shifting, swaying, or twisting.

[0026] Furthermore, the follower is designed to rotate and move relative to the support frame, providing a high degree of freedom and adapting to complex winding trajectories. This ensures that the wire can be accurately wound onto the winding die along a predetermined path, thereby improving the winding quality and coil forming accuracy.

[0027] The present invention also discloses a winding production line suitable for stellarator three-dimensional superconducting coils. The follower support device further includes a support shaft. The follower is movably mounted on the support frame through the support shaft. The axis of the support shaft is the first axis.

[0028] The support shaft is mounted on the support frame, and the follower is set as a follower guide wheel. The follower guide wheel is sleeved on the outer periphery of the support shaft and can move relative to the support shaft along the direction of the first axis. The guide groove is set on the outer wall of the follower guide wheel.

[0029] Using the above technical solution, with the support shaft as the first axis, the follower guide wheel is sleeved on the outer circumference of the support shaft and can rotate around it. At the same time, it can also move relative to the support shaft along the first axis. When the superconducting conductor undergoes positional changes, such as swinging or moving, the follower guide wheel can precisely adjust its own position by rotating around the support shaft and moving along the axial direction, always providing stable and accurate guidance for the wire. This effectively avoids wire deviation, swinging or twisting, improves the winding quality, and the rotatable follower guide wheel has a high degree of freedom and low friction, resulting in stable rotation and a long service life.

[0030] The present invention also discloses a winding production line suitable for three-dimensional superconducting coils of stellarators. The support shaft is fixedly mounted on the support frame, and the follower guide wheel can rotate relative to the support shaft around the first axis and can move relative to the support shaft along the direction of the first axis.

[0031] Alternatively, the support shaft can be rotatably mounted on the support frame about the first axis, and the follower guide wheel can be fixed relative to the support shaft along its circumference, so that the overall structure formed by the follower guide wheel and the support shaft can rotate relative to the support frame about the first axis, and the follower guide wheel can move relative to the support shaft in the direction of the first axis.

[0032] More preferably, a limiting rod is also fixedly provided on the top of the support frame, and the limiting rod and the support shaft are spaced apart relative to each other along the height direction of the support frame; the direction of the first axis is perpendicular to the height direction of the support frame.

[0033] Using the above technical solution, the limiting rod and the support shaft are set at relative intervals along the height direction of the support frame, and the first axis direction is perpendicular to the height direction of the support frame. During the winding process, when the follower guide wheel guides the superconducting conductor, it may swing due to factors such as changes in the tension and strain of the wire. The limiting rod limits the superconducting conductor in the height direction, thereby avoiding the risk of the superconducting conductor detaching from the follower guide wheel due to excessive swing amplitude, and ensuring that the follower guide wheel always works within the predetermined range of motion.

[0034] Furthermore, multiple follower support devices are configured, and these multiple follower support devices are spaced apart between the wire feeding device and the wire winding device along the transmission direction of the superconducting conductor.

[0035] By adopting the above technical solution and setting up multiple follow-up support devices, the transport stability of the superconducting conductor is higher when winding the superconducting coil. When the position of the superconducting conductor shifts or swings, it provides stable support for the superconducting conductor. Attached Figure Description

[0060] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0061] This embodiment discloses a winding production line suitable for stellarator three-dimensional superconducting coils. Please refer to [link to relevant documentation]. Figure 1 The winding production line includes a wire feeding device 100, a centering calibration device 500, a conductor straightening device 600, a sandblasting device 700, a follow-up support device 300, and a winding device 400 arranged in sequence.

[0062] Please see Figure 1 as well as Figure 2 The wire feeding device 100 includes a wire feeding roller 110, which is used to wind the superconducting conductor 200 and release the superconducting conductor 200.

[0063] Please see Figure 1 and Figure 3 The centering calibration device 500 is located downstream of the wire feeding device 100 along the transmission direction of the superconducting conductor. The centering calibration device 500 is used to center and calibrate the superconducting conductor 200 released from the wire feeding roller 110.

[0064] Please see Figure 1 and Figure 4 The conductor straightening device 600 is disposed downstream of the centering calibration device 500 along the transmission direction of the superconducting conductor 200. The conductor straightening device 600 is used to straighten the superconducting conductor 200 after centering calibration.

[0065] Please see Figure 1 and Figure 5 The sandblasting device 700 is located downstream of the conductor straightening device 600 along the transmission direction of the superconducting conductor 200. The sandblasting device 700 is used to sandblast the outer wall of the superconducting conductor 200 after it has been straightened by the conductor straightening device 600.

[0066] Please see Figure 1 and Figure 6The follower support device 300 includes a movable follower 310, which is used for the superconducting conductor 200 released by the pay-off roller 110 to bypass, and the superconducting conductor 200 can move synchronously with the follower 310.

[0067] Please see Figure 1 and Figure 7 The winding device 400 includes a ring-shaped winding mold 410, which can rotate about a preset axis, and the winding mold 410 is used to wind a superconducting conductor 200 wound from the follower 310 of the follower support device 300 to form a stellarator three-dimensional superconducting coil.

[0068] Please see Figure 1 Along the transmission direction of the superconducting conductor 200, the winding production line is provided with a wire feeding device 100, a centering calibration device 500, a conductor straightening device 600, a sandblasting device 700, a follower support device 300, and a winding device 400 in sequence at intervals. The follower support device 300 is located upstream of the winding device 400 and downstream of all other devices.

[0069] It should be noted that the specific structure of the wire feeding device 100 in this embodiment is not limited. The wire feeding roller 110 can be a component such as an air shaft or a rotating shaft. A material roll or other component can be sleeved on the air shaft or rotating shaft. The wire feeding roller 110 can also be a material roller with a superconducting conductor 200 wound on it. When winding the three-dimensional superconducting coil of the stellarator, the wire feeding roller 110 rotates and releases the superconducting conductor 200 wound on it. The wire feeding roller 110 can rotate passively or actively to release the superconducting conductor 200. Those skilled in the art can design or select according to actual needs.

[0070] For example, see Figure 2 In this embodiment, a material roll 120 is sleeved on the wire feeding roller 110. The wire feeding roller 110 rotates automatically. A damping disk 130 is also provided on one side of the wire feeding roller 110. The damping disk 130 can prevent the wire feeding speed of the wire feeding roller 110 from being too fast.

[0071] It should be noted that the superconducting conductor 200 can move synchronously with the follower 310, meaning that the follower 310 can move freely on the follower support device 300. The follower 310 can rotate on its own axis and can also swing or move relative to the follower support device 300. When the position of the superconducting conductor 200 changes, such as when the superconducting conductor 200 swings or shifts, the follower 310 can move synchronously with the superconducting conductor 200, and the follower 310 always provides support for the superconducting conductor 200.

[0072] With the above-described structure, after the superconducting conductor 200 is released from the wire release device 100, it is sequentially transported through the centering calibration device 500 for centering calibration (to avoid excessive deviation in the transport direction), and then transported to the conductor straightening device 600 for precise straightening. After straightening, it is transported to the sandblasting device 700 to sandblast the outer wall of the superconducting conductor 200. After sandblasting, the superconducting conductor 200 is wound onto the winding mold 410 of the winding device 400 after passing through the follower 310, and finally wound to form a stellarator three-dimensional superconducting coil.

[0073] Furthermore, the movable follower 310 in the follower support device 300 provides dynamic support for the superconducting conductor 200. During the winding process, when the winding device 400 drives the winding die 410 to rotate, the superconducting conductor 200 will be subjected to various forces, causing it to tend to deviate, oscillate, or twist. The follower 310 can move synchronously with the movement of the superconducting conductor 200, adjusting the support position and angle of the wire in a timely manner, providing a stable guiding and support path for the wire, effectively suppressing the twisting of the superconducting conductor 200 after deviation or oscillation, improving the winding quality of the superconducting coil, and thus reducing the risk of coil winding failure.

[0074] When the winding die 410 rotates during the winding process, for example, when the rotary table 420 drives the winding die 410 to rotate, during the process of completing the three-dimensional trajectory winding of the conductor, the rotation of the winding die 410 will cause the superconducting conductor 200 to move or swing. The superconducting conductor 200 may shift left or right along its transmission direction. For example, when the superconducting conductor 200 shifts to the left or swings during the winding process, the follower 310 can move to the left with the superconducting conductor 200. When the superconducting conductor 200 shifts to the right or swings during the winding process, the follower 310 can move to the right with the superconducting conductor 200, providing stable support and guidance for the superconducting conductor 200. It can also prevent the superconducting conductor 200 from swinging too much or even twisting, thereby improving the winding quality of the superconducting coil and reducing the risk of coil winding failure.

[0075] Next, the specific structure of the winding device 400 will be explained and described in detail:

[0076] Please see Figure 7 The winding device also includes a rotary table 420 and a drive unit (not shown in the figure), and the winding die 410 is fixed to the rotary table 420. The drive unit is used to drive the rotary table 420 to rotate, so as to drive the winding die 410 fixed to the rotary table 420 to rotate around a preset axis.

[0077] It should be noted that the specific structure and driving method of the driving component are not limited. For example, the driving component can be a drive motor, and the output end of the drive motor can be equipped with a drive belt, drive gear, etc. to drive the rotary table 420 to rotate.

[0078] Using the above technical solution, the driving component drives the rotary table 420 to rotate, and the winding mold 410 fixed to the rotary table 420 rotates around the preset axis. Then, the superconducting conductor 200 is wound around the winding mold 410 one turn at a time to form a stellarator three-dimensional superconducting coil. In this embodiment, the preset axis can be the same axis direction as the vertical direction.

[0079] Further preferred, please refer to Figure 7 In this embodiment, the winding mold includes an annular support base 411, an inner side plate 412, and an outer side plate 413. The inner side plate 412 and the outer side plate 413 are spaced apart along the radial direction of the support base 411 and are both fixed to the top of the support base 411. The top of the support base 411, the inner side plate 412, and the outer side plate 413 together define an annular winding groove. The superconducting conductor is wound sequentially around the winding groove to form a stellarator three-dimensional superconducting coil. The outer peripheral surface of the inner side plate 412 is used to adapt to the inner peripheral surface of the stellarator three-dimensional superconducting coil, and the inner peripheral surface of the outer side plate 413 is used to adapt to the outer peripheral surface of the stellarator three-dimensional superconducting coil.

[0080] With the above-mentioned structural design, the top of the support base 411, the inner side plate 412 and the outer side plate 413 together surround and define a ring-shaped winding groove, the winding trajectory is controllable, and the problems of wire deviation and twisting deformation can be avoided. The inner side plate 412 and the outer side plate 413 are matched radially to constrain the inner and outer contours of the stellarator three-dimensional superconducting coil, ensuring the forming size and positional accuracy of the stellarator three-dimensional coil.

[0081] Next, the specific structures of the centering calibration device 500, the conductor straightening device 600, and the sandblasting device 700 will be explained in detail:

[0082] Please see Figure 1 and Figure 3 The centering calibration device 500 is positioned downstream of the wire feeding device 100 and upstream of the follower support device 300 along the transmission direction of the superconducting conductor 200.

[0083] Please continue reading Figure 3 The centering calibration device 500 includes a horizontal calibration component and a vertical calibration component. The horizontal calibration component includes a plurality of rotatable horizontal calibration rollers 510 spaced apart on both sides of the superconducting conductor 200 in the horizontal direction. The vertical calibration component includes a plurality of rotatable vertical calibration rollers 520 spaced apart on both sides of the superconducting conductor 200 in the vertical direction.

[0084] It should be noted that the specific number of horizontal calibration rollers 510 is not limited, for example, it can be 2, 3, 4 or other numbers, and the specific number of vertical calibration rollers 520 is also not limited, for example, it can be 2, 3, 4 or other numbers.

[0085] Preferably, see Figure 3 In this embodiment, two horizontal calibration rollers 510 and two vertical calibration rollers 520 are provided. The two horizontal calibration rollers 510 and the two vertical calibration rollers 520 form a square central calibration space in the middle. Therefore, the horizontal calibration components and the vertical calibration components can relatively constrain the superconducting conductor 200 in a central position, ensuring the accurate transmission of the superconducting conductor 200 in the horizontal direction and preventing the superconducting conductor 200 from deviating excessively from the transmission path. In other words, the central calibration device 500 performs preliminary limiting and central guidance on the superconducting conductor 200 output from the wire feeding device 100, preventing the superconducting conductor 200 from deviating too much.

[0086] See further Figure 1 and Figure 4 The conductor straightening device 600 is positioned downstream of the central calibration device 500 and upstream of the follower support device 300 along the transmission direction of the superconducting conductor 200. The conductor straightening device 600 includes a plurality of driving wheels 610 and a plurality of driven wheels 620 arranged alternately along the transmission direction of the superconducting conductor 200, with a straightening channel 630 formed between the driving wheels 610 and the driven wheels 620 for the superconducting conductor 200 to pass through. The straightening channel 630 is used for the superconducting conductor 200 to pass through, thereby precisely straightening the superconducting conductor 200.

[0087] Please see Figure 4 The conductor straightening device 600 also includes an adjustment assembly 640, which can adjust the position of one or more of the plurality of driving wheels 610 or the plurality of driven wheels 620 in the height direction. The conductor device also includes a scale 650 for displaying the dimensions of the straightening channel 630.

[0088] It should be noted that in this embodiment, the specific number of driving wheels 610 and driven wheels 620 is not limited, and the number of driving wheels 610 and driven wheels 620 can be the same or different. For example, the number of driving wheels 610 can be 2, 3, 4, 5 or other numbers, and the number of driven wheels 620 can also be 2, 3, 4, 5 or other numbers. This embodiment does not make specific limitations on this.

[0089] Furthermore, in this embodiment, the passive wheel 620 is positioned above and the active wheel 610 is positioned below. The specific structure of the adjustment component 640 is not limited. For example, the adjustment component 640 can be an adjustment wheel and a screw drive component. The screw drive component is connected to the active wheel 610 or the passive wheel 620. The adjustment rotation can drive the screw drive component to rotate, and the screw drive component can drive the active wheel 610 or the passive wheel 620 to move and adjust along the height direction. The adjustment component 640 can also be configured as a drive cylinder, a drive hydraulic cylinder, etc., which can also drive the active wheel 610 or the passive wheel 620 to move and adjust along the height direction.

[0090] In this embodiment, the ability of the adjustment component 640 to adjust the position of one or more of the multiple driving wheels 610 or multiple driven wheels 620 in the height direction means that: the adjustment component 640 can simultaneously drive the multiple driving wheels 610 in the height direction; or the adjustment component 640 can simultaneously drive the multiple driven wheels 620 in the height direction; or the adjustment component 640 can drive a single driving wheel 610 in the height direction respectively; or the adjustment component 640 can drive a single driven wheel 620 in the height direction respectively.

[0091] For example, see Figure 4 The passive wheel 620 is positioned above the active wheel 610, and three passive wheels 620 are spaced apart. Each passive wheel 620 has an adjustment component 640 on one side. The adjustment component 640 can adjust the position of the corresponding passive wheel 620 in the height direction, thereby adjusting the straightening channel 630 through which the superconducting conductor 200 passes.

[0092] After the superconducting conductor 200 passes through the straightening channel 630, it is pressed and straightened in sequence by multiple driving wheels 610 and multiple driven wheels 620. In other words, the conductor straightening device 600 can eliminate the bending deformation of the superconducting conductor 200 before winding, ensuring that the superconducting conductor 200 has a certain straightness, laying the foundation for subsequent precise winding.

[0093] Please see Figure 1 and Figure 5 The sandblasting device 700 is disposed between the conductor straightening device 600 and the follow-up support device 300 along the transmission direction of the superconducting conductor 200. The sandblasting device 700 includes a sandblasting machine 710 and at least one cleaning auxiliary machine 720 located on one side of the sandblasting machine 710. The sandblasting machine 710 has a sandblasting chamber (not shown in the figure) inside, and a sandblasting port (not shown in the figure) is provided in the sandblasting chamber. The sandblasting machine 710 has an inlet and an outlet (not shown in the figure) at both ends for the superconducting conductor 200 to pass through, and a seal (not shown in the figure) is provided at both the inlet and the outlet. The cleaning auxiliary machine 720 is configured as a dust collector.

[0094] It should be noted that the specific number of cleaning auxiliary machines 720 is not limited. For example, there can be one, two, three or more cleaning auxiliary machines 720. In this embodiment, two are preferably provided. Both cleaning auxiliary machines 720 are dust collectors, and the two cleaning auxiliary machines 720 are respectively set on both sides of the sandblasting machine 710.

[0095] With this structural design, the sandblasting device 700 uses high-pressure airflow to spray abrasive onto the surface of the superconducting conductor 200, removing the surface oxide layer and forming a uniform rough texture, thus improving the surface friction and resin adhesion. The dust collector can clean the sandblasted superconducting conductor 200.

[0096] The following is a more detailed description of the follower support device 300 for a stellarator three-dimensional superconducting coil winding production line provided in this embodiment:

[0097] Please see Figure 6 The follower support device 300 also includes a support frame 320. A follower 310 is movably mounted on the support frame 320. The follower 310 can rotate relative to the support frame 320 about a first axis and can move relative to the support frame 320 along the direction of the first axis. The follower 310 is provided with a wire groove 311 for adaptation to the superconducting conductor 200. The direction of the first axis is as follows... Figure 6 As shown in the A direction.

[0098] It should be noted that the specific structure of the follower 310 in this embodiment is not limited. For example, the follower 310 can be a slider, a roller, or other components. For example, when it is set as a slider, the slider can move along the direction of the first axis and the wire groove 311 is set in the middle of the slider. The slider provides stable support and guidance for the superconducting conductor 200. For example, when it is set as a roller, the wire groove 311 is set on the outer wall of the roller, which also provides stable support and guidance for the superconducting conductor 200.

[0099] Therefore, in this embodiment, the support frame 320 provides structural support for the follower 310. The follower 310 can rotate relative to the support frame 320 around the first axis, and can also move relative to the support frame 320 along the direction of the first axis. Therefore, the follower 310 has a high degree of freedom. When the superconducting conductor 200 deviates in position or angle, the follower 310 readjusts to the position of the wire by rotating and moving, always providing stable and accurate support and guidance for the superconducting conductor 200, effectively preventing problems such as torsion caused by deviation or swaying of the superconducting conductor 200.

[0100] Furthermore, the follower 310 is configured to rotate and move relative to the support frame 320, which has a high degree of freedom and can adapt to complex winding trajectories, ensuring that the wire can be accurately wound on the winding mold 410 according to the predetermined path, thereby improving the winding quality and coil forming accuracy.

[0101] Please continue reading Figure 6 The follower support device 300 also includes a support shaft 330. The follower 310 is movably mounted on the support frame 320 via the support shaft 330, and the axis of the support shaft 330 is the first axis. The support shaft 330 is mounted on the support frame 320, and the follower 310 is configured as a follower guide wheel. The follower guide wheel is sleeved on the outer periphery of the support shaft 330 and can move relative to the support shaft 330 along the direction of the first axis. A guide groove 311 is provided on the outer wall of the follower guide wheel.

[0102] With this structural design, the support shaft 330 serves as the first axis. The follower guide wheel is sleeved around the support shaft 330 and can rotate around it. It can also move relative to the support shaft 330 along the first axis. When the superconducting conductor 200 undergoes positional changes, such as swinging or moving, the follower guide wheel precisely adjusts its position by rotating around the support shaft 330 and moving along the axial direction. This provides stable and accurate guidance for the superconducting conductor 200, effectively preventing the superconducting conductor 200 from shifting, swinging, or twisting, thus improving the winding quality. Furthermore, the rotatable follower guide wheel has a high degree of freedom and low friction, resulting in stable rotation and a long service life.

[0103] Furthermore, the support shaft 330 can be fixedly mounted on the support frame 320, and the follower guide wheel can rotate relative to the support shaft 330 around the first axis and can move relative to the support shaft 330 along the direction of the first axis.

[0104] With this structural design, the support shaft 330 is fixed on the support frame 320, and the follower guide wheel can rotate or move around the support shaft 330.

[0105] Alternatively, the support shaft 330 can be rotatably mounted on the support frame 320 around the first axis, and the follower guide wheel can be fixed relative to the support shaft 330 along its circumference, so that the overall structure formed by the follower guide wheel and the support shaft 330 can rotate relative to the support frame 320 around the first axis, and the follower guide wheel can move relative to the support shaft 330 along the direction of the first axis.

[0106] With this design, the support shaft 330 is rotatably mounted on the support frame 320, and the follower guide wheel can move relative to the support shaft 330 along the direction of the first axis. For example, when the support shaft 330 is set as a square shaft or other irregular shaft, the follower guide wheel and the support shaft 330 as a whole can rotate relative to the support frame 320 around the first axis, and at the same time, the follower guide wheel can move relative to the support shaft 330.

[0107] For further information, please see [link / reference]. Figure 6 A limiting rod 340 is also fixedly installed on the top of the support frame 320. The limiting rod 340 and the support shaft 330 are spaced apart relative to each other along the height direction of the support frame 320. The direction of the first axis is perpendicular to the height direction of the support frame 320.

[0108] In this design, the limiting rod 340 and the support shaft 330 are spaced apart relative to each other along the height direction of the support frame 320, and the first axis direction is perpendicular to the height direction of the support frame 320. During the winding process, when the follower guide wheel guides the superconducting conductor 200, it may swing due to factors such as changes in wire tension. The limiting rod 340 limits the superconducting conductor 200 in the height direction to prevent the superconducting conductor 200 from detaching from the follower guide wheel due to excessive swing amplitude, ensuring that the follower guide wheel always works within the predetermined range of motion. That is, see Figure 3 When the superconducting conductor 200 is being transported, if there is any deviation or swing, it will only be transported within the area enclosed by the limiting rod 340, the support shaft 330 and the support frame 320, and there will be no excessive deviation or swing.

[0109] The embodiments of this invention also disclose a winding production line suitable for stellarator three-dimensional superconducting coils. Multiple follower support devices 300 are provided, and the multiple follower support devices 300 are spaced apart between the wire feeding device 100 and the winding device 400 along the transmission direction of the superconducting conductor 200.

[0110] It should be noted that the specific number of follow-up support devices 300 is not limited; for example, it can be 2, 3, 4, or other numbers, as shown in [reference needed]. Figure 1 In this embodiment, two follow-up support devices 300 are provided at intervals.

[0111] For designs employing this structure, please refer to [link / reference]. Figure 1In this embodiment, two follower support devices 300 are provided, which improves the transport stability of the superconducting conductor 200 when winding the superconducting coil. When the position of the superconducting conductor 200 shifts or swings, the two follower support devices 300 provide stable support for the superconducting conductor 200. Furthermore, when the swing of the superconducting conductor 200 is too large, the two follower support devices 300 can disperse the swing angle of the superconducting conductor 200, distributing the tension and impact load of the superconducting conductor 200 to two support points, avoiding local stress concentration. This not only buffers the impact deformation caused by the large swing of the superconducting conductor 200, preventing damage to the superconducting conductor 200 due to bending and pulling, but also constantly constrains the routing trajectory of the superconducting conductor 200.

[0112] Finally, a brief description of the winding process of the production line for winding three-dimensional superconducting coils for stellarators disclosed in this utility model is provided:

[0113] Step 1, wire feeding operation: Install the wire roll 120 on the wire feeding roller 110 of the wire feeding device 100, adjust the wire feeding device 100 and adjust the wire feeding tension. After starting the wire feeding device 100, the superconducting conductor 200 can be fed out at a stable speed.

[0114] Step 2, centering and straightening the superconducting conductor 200: The superconducting conductor 200 is centered and straightened by passing through the horizontal calibration roller 510 and the vertical calibration roller 520, so that it can enter the straightening device directly.

[0115] Step 3, Precision straightening of superconducting conductor 200: The superconducting conductor 200 enters the conductor straightening device 600. The vertical distance between the driving wheel 610 and the driven wheel 620 (including but not limited to the two wheels) is adjusted by the adjusting component 640 to make the driving wheel 610 and the driven wheel 620 in close contact with the surface of the superconducting conductor 200. The superconducting conductor 200 completes multi-directional precision straightening when passing through multiple driving wheels 610 and driven wheels 620 to ensure the straightness of the superconducting conductor 200.

[0116] Step 4, sandblasting: The straightened superconducting conductor 200 enters the sandblasting chamber of the sandblasting device 700, and then undergoes dry sandblasting with alumina micro-abrasive to roughen the surface of the superconducting conductor 200.

[0117] Step 5, follow-up support conveying: The sandblasted superconducting conductor 200 passes through two follow-up support devices 300 in sequence. The limiting rod 340 of each follow-up support device 300 ensures that the superconducting conductor 200 will not swing to the outside. The follower 310 (follower guide wheel) is rotatably and movablely set on the support shaft 330. The superconducting conductor 200 swings synchronously with the subsequent rotary table 420. The conductor is free from torsion and deformation through the rolling contact between the follower 310 and the superconducting conductor 200 and the adjustment of its position.

[0118] Step 6, Three-dimensional winding: The end of the superconducting conductor 200 passing through the follower support device 300 is fixed at a preset position on the winding mold 410 on the rotary table 420. The winding mold 410 is fixed on the winding support frame (e.g., support base 411), and the winding support frame is fixed to the rotary table 420. As the rotary table 420 rotates, it drives the winding mold 410 to rotate, and the superconducting conductor 200 is continuously wound on the winding mold 410 according to a preset three-dimensional trajectory until the overall winding of the stellarator three-dimensional superconducting coil is completed.
