Description

Technical Field

[0001] The invention belongs to the technical field of coil winding, in particular to a tape winding machine for winding multiple strands of tape materials in a plane spiral track. Background Art

[0002] The application of coils is involved in fields such as superconducting magnets and controlled nuclear fusion tokamak devices. Among them, the tokamak device contains a very important toroidal field coil. One of the manufacturing steps of this coil is to bundle multiple superconducting tapes into a bundle and wind them on a stainless steel frame with a flat spiral groove.

[0003] Superconducting magnets are electromagnets made from coils of superconducting wire. In their superconducting state, the wire has no resistance, allowing it to conduct much greater currents than ordinary wires, generating strong magnetic fields. Superconducting magnets can generate stronger magnetic fields than non-superconducting electromagnets, and large superconducting magnets are cheaper to operate because no energy is dissipated as heat in the windings. They are used in hospital MRI machines and in scientific equipment such as nuclear magnetic resonance spectrometers, mass spectrometers, fusion reactors, and particle accelerators.

[0004] Currently, commonly used coils, such as high-temperature superconducting tape made from rare earth barium copper oxide (REBCO), are somewhat brittle. They can bend above a minimum bending radius, but they cannot kink. During the tape winding process, especially when the tape is large and long, kinking can easily occur, damaging the tape.

[0005] Currently, tape winding machines or wire winding machines are required for winding strips in various industries. However, existing tape winding machines generally only wind one strand of strip per reel, and no equipment or patents for winding multiple strands of strips simultaneously have been found. Therefore, there is an urgent need for a tape winding machine that can wind multiple strands of strips on a flat spiral track. Summary of the Invention

[0028] The following embodiments further illustrate a specific embodiment of a tape winding machine for winding multiple strands of tape in a planar spiral track according to the present invention. The tape winding machine for winding multiple strands of tape in a planar spiral track according to the present invention is not limited to the description of the following embodiments.

[0029] Example: A tape winding machine that winds multiple strands of tape into a flat spiral track, such as Figure 1-9 As shown, it includes a rotating table 3 and several unloading tables 1 on one side thereof. A wire harness integrated disk 4 is provided on the rotating table 3, and several tape reels 2 are provided on the unloading table 1. Several tapes on the several tape reels 2 are gathered into a wire harness and wound in the wire harness integrated disk 4.

[0030] In one possible embodiment, the tape winding machine consists of several unwinding tables 1 (the specific number depends on the required tape quantity) and a rotating platform. Each unwinding table 1 is equipped with several tape reels 2, which store a certain length of superconducting tape (or other tape material). The superconducting tapes are then bundled together and pulled toward a stainless steel frame to be wound. The stainless steel frame is fixed to the rotating platform, which rotates to wind all the tape material into grooves.

[0031] In a possible embodiment, a plurality of unloading platforms 1 are respectively arranged on both sides of the straight line where the wire harness is located, and the plurality of unloading platforms 1 are staggered.

[0032] In one possible embodiment, a reel shaft 21 is provided at the center of the reel 2 through a reel mounting flange 22. The reel shaft 21 is rotatably connected to the surface of the unloading table 1 through a reel bearing seat 23. The lower end of the reel shaft 21 is connected to the output shaft of the reel motor 24 through a torque retainer 25.

[0033] In one possible embodiment, an array of guide wheel assemblies 5 corresponding one-to-one to a plurality of tape reels 2 is provided on one side of the unloading table 1 close to the wiring harness, and an anti-interference device 6 is provided on one end of the unloading table 1 close to the rotating table 3. After the free ends of the tapes on the plurality of tape reels 2 pass through their corresponding guide wheel assemblies 5, they pass through the anti-interference device 6 together.

[0034] In a possible embodiment, the guide wheel assembly 5 includes a strip guide wheel 51 , a guide wheel shaft 52 is rotatably provided at the bottom center of the strip guide wheel 51 , and the guide wheel shaft 52 is connected to the unloading platform 1 .

[0035] In one possible embodiment, the anti-clutter device 6 includes a strip pad 62 provided at a corner of the unloading table 1 near the top of the rotating table, two anti-clutter guide wheels 63 are provided on the top of the strip pad 62, and a strip cover 64 is provided on the top of the two anti-clutter guide wheels 63. There is a gap between the two anti-clutter guide wheels 63, and a mounting rod 61 is rotatably provided at the center of the two anti-clutter guide wheels 63. The mounting rod 61 passes through the strip pad 62, the strip cover 64 and the surface of the unloading table 1, and the upper and lower ends of the mounting rod 61 are positioned by bolts.

[0036] In one possible embodiment, the unloading table 1 is supported by a welded steel frame with a metal panel on the top, on which are mounted N groups of tape reels 2 and an equal number of guide wheel assemblies 5 and an anti-interference device 6; the tape reels 2 are fixed to the metal panel through the tape reel shaft 21 and the tape reel bearing seat 23, and the other end of the tape reel shaft 21 is connected to the tape reel motor 24 through a torque retainer 25. When winding the tape, the tape reel motor 24 does not rotate, and the torque retainer 25 provides tension to make the tape taut. When the wound tape needs to be unwound, the tape reel motor 24 can be rotated in the opposite direction, and the rotating platform can also be rotated in the opposite direction, so that each tape can be unwound into the corresponding tape reel 2.

[0037] In a possible implementation, the torque retainer 25 may be replaced by a magnetic powder clutch, which can also adjust the magnitude of the resistance, thereby controlling the magnitude of the tension during the strip winding process.

[0038] In one possible embodiment, an engineering plastic plate is mounted on the metal panel. The upper surface of the engineering plastic plate is at the same height as or slightly lower than the inner side of the reel to support the superconducting tape and prevent the superconducting tape from sagging too much and bending.

[0039] In one possible embodiment, the two anti-traffic guide wheels 63 of the anti-traffic device 6, the strip cover 64, and the strip pad 62 confine the strip to a square space, preventing it from scattering. One of the anti-traffic guide wheels 63 can be adjusted so that the distance between them is slightly larger than the width of the strip bundle, allowing the strip bundle to pass smoothly without scattering.

[0040] In a possible embodiment, each unwinding table is provided with a retainer for keeping the strips in order to prevent the strips from becoming scattered.

[0041] In a possible embodiment, a spiral groove 41 is opened on the outside of the wiring harness integrated disk 4 , a clamping mechanism 7 is provided at the inner end of the spiral groove 41 , and a belt pressing plate 8 is provided on one side of the clamping mechanism 7 .

[0042] In one possible embodiment, the clamping mechanism 7 includes a clamping base 71, which is fixed to the inner end of the spiral groove 41. A clamping groove 72 is provided at the bottom of the clamping base 71, and a pressing tongue 73 is provided in the clamping groove 72. A plurality of fastening bolts 74 are screwed onto the side of the clamping groove 72. The wiring harness passes through the clamping groove 72, and the fastening bolts 74 are rotated to squeeze and move the pressing tongue 73 to fix the wiring harness.

[0043] In a possible implementation, the rotating platform 3 is an existing device, which drives the wiring harness integrated disk 4 to rotate via a motor reducer.

[0044] In one possible embodiment, the inner and outer lengths of a single turn of the spiral groove 41 are inconsistent. During the winding process, a length difference will occur between the inner and outer sides of the tape bundle (a collection of multiple strands of tape is called a tape bundle). As the number of winding turns increases, the length difference will become larger and larger. Therefore, the problem of the length difference on both sides needs to be solved during the winding process. Otherwise, the tape will become scattered, which will cause the superconducting tape to bend and be damaged, resulting in quenching.

[0045] Furthermore, the solution to the length difference between the inner and outer rings is: because each strip has a certain tension, the strip is always taut during the winding process, which will automatically cause the strips at different positions of the inner and outer rings to slide relative to each other, thereby automatically compensating for the length difference between the inner and outer rings, so that the strips always remain neat during the winding process.

[0046] In one possible embodiment, the starting ends of the strip bundle are brought together and secured to a rotating platform using a clamping mechanism 7. The clamping mechanism 7 uses screws to press the strip bundle together, thereby clamping it. Because the clamping mechanism 7 is higher than the stainless steel frame, a belt pressing mechanism 8 is added to the clamping mechanism 7. This is a flat plate with one end secured to the rotating platform by screws and the other end pressing the strip bundle into the groove.

[0047] In one possible embodiment, during the strip winding process, the operator holds down the strip that has entered the slot with one hand (to prevent the strip that has entered the slot from being pulled out), and uses the other hand to constantly adjust the strip that is about to enter the slot, while adjusting it.

[0048] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
