Description

Technical Field

[0001] This invention belongs to the field of coil winding technology, specifically a winding machine for winding multiple strands of strip material in a planar helical track. Background Technology

[0002] Coils are used in fields such as superconducting magnets and controlled nuclear fusion tokamak devices. Among them, tokamak devices contain a very important toroidal field coil. One of the manufacturing steps of this coil is to bundle multiple superconducting strips together and wind them onto a stainless steel frame with planar helical grooves.

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

[0004] Currently used coils, such as high-temperature superconducting tapes made of rare-earth barium copper oxide (REBCO), have a certain degree of brittleness. They can be bent at a radius exceeding the minimum bending radius, but cannot be completely bent. During the tape winding process, especially when the tape is numerous and long, it is easy for it to bend and be damaged.

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

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a winding machine for winding multiple strips in a planar helical track.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A winding machine for winding multiple strips in a planar helical track includes a rotary table and several feeding tables on one side. The rotary table is provided with a wire harness integration disk, and the feeding tables are provided with several strip reels. Several strips on the several strip reels converge into a wire harness and are wound in the wire harness integration disk.

[0009] Preferably, the plurality of feeding platforms are respectively located on both sides of the straight line where the wire harness is located, and the plurality of feeding platforms are staggered.

[0010] Preferably, a belt reel shaft is provided at the center of the belt reel via a belt reel mounting flange. The belt reel shaft is rotatably connected to the unloading table surface via a belt reel bearing seat. The lower end of the belt reel shaft is connected to the output shaft of the belt reel motor via a torque retainer.

[0011] Preferably, the feeding platform is provided with guide roller assemblies corresponding to several reels on one side near the wire harness, and an anti-disorder device is provided at the end of the feeding platform near the rotary table. The free ends of the strips on several reels pass through their corresponding guide roller assemblies and then pass through the anti-disorder device together.

[0012] Preferably, the guide wheel assembly includes a strip guide wheel, and a guide wheel shaft is rotatably provided at the bottom center of the strip guide wheel, the guide wheel shaft being connected to the feeding table.

[0013] Preferably, the anti-disorder device includes a strip pad located at one corner of the top of the feeding platform near the top of the rotating platform. The top of the strip pad is provided with two anti-disorder guide wheels, and the top of the two anti-disorder guide wheels is provided with a strip cover. There is a gap between the two anti-disorder guide wheels, and a mounting rod is rotatably provided at the center of each of the two anti-disorder guide wheels. The mounting rod passes through the strip pad, the strip cover and the surface of the feeding platform, and the upper and lower ends of the mounting rod are positioned by bolts.

[0014] Preferably, the outer side of the wire harness integration disc is provided with a spiral groove, the inner end of the spiral groove is provided with a clamping mechanism, and a pressure plate is provided on one side of the clamping mechanism.

[0015] Preferably, the clamping mechanism includes a clamping base, which is fixed to the inner end of the spiral groove. The bottom of the clamping base is provided with a clamping groove, and a pressure tongue is provided in the clamping groove. Several fastening bolts are screwed to the side of the clamping groove. The wire harness passes through the clamping groove, and the wire harness is fixed by rotating the fastening bolts to squeeze and move the pressure tongue.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In this invention, multiple strips are formed into a wire harness by a guide wheel assembly, and multiple strips are prevented from tangling and becoming disordered by an anti-tangle device. This allows multiple strips to be wound simultaneously in a planar spiral groove, and provides good protection for the strips, preventing damage to them. Attached Figure Description

[0038] The following embodiments further illustrate specific implementations of a winding machine for winding multi-strand strips within a planar helical track according to the present invention. The winding machine for winding multi-strand strips within a planar helical track according to the present invention is not limited to the descriptions in the following embodiments.

[0039] Example:

[0040] A winding machine that winds multiple strips of material into a planar helical track, such as Figure 1-9 As shown, it includes a rotary table 3 and several feeding tables 1 on one side. The rotary table 3 is provided with a wire harness integration disk 4, and the feeding tables 1 are provided with several tape reels 2. Several tapes on the tape reels 2 are gathered into a wire harness and wound inside the wire harness integration disk 4.

[0041] In one possible implementation, the winding machine consists of several feeding platforms 1 (the specific number depends on the amount of strip material needed) and a rotating platform. Each feeding platform 1 has several reels 2, each holding a certain length of superconducting strip (or other strip material). The superconducting strips are sequentially gathered into a bundle and pulled towards the same end to the stainless steel frame to be wound. The stainless steel frame is fixed to the rotating platform, and during rotation, the platform winds all the strip material into the grooves.

[0042] In one possible implementation, several feeding platforms 1 are respectively located on both sides of the straight line where the wire harness is located, and the feeding platforms 1 are staggered.

[0043] In one possible implementation, a belt reel shaft 21 is provided at the center of the belt reel 2 via a belt reel mounting flange 22. The belt reel shaft 21 is rotatably connected to the surface of the feeding table 1 via a belt reel bearing seat 23. The lower end of the belt reel shaft 21 is connected to the output shaft of the belt reel motor 24 via a torque retainer 25.

[0044] In one possible implementation, the feeding platform 1 is provided with an array of guide roller assemblies 5 on the side near the wire harness, corresponding one-to-one with a number of reels 2. The feeding platform 1 is provided with an anti-disorder device 6 at the end near the rotary table 3. The free ends of the strips on the reels 2 pass through their corresponding guide roller assemblies 5 and then pass through the anti-disorder device 6 together.

[0045] In one possible implementation, the guide wheel assembly 5 includes a strip guide wheel 51, and a guide wheel shaft 52 is rotatably provided at the bottom center of the strip guide wheel 51. The guide wheel shaft 52 is connected to the feeding table 1.

[0046] In one possible implementation, the anti-disorder device 6 includes a strip pad 62 located at one corner of the top of the feeding platform 1 near the top of the rotary table. The top of the strip pad 62 is provided with two anti-disorder guide wheels 63, and the top of the two anti-disorder guide wheels 63 is provided with a strip cover 64. There is a gap between the two anti-disorder guide wheels 63, and a mounting rod 61 is rotatably provided at the center of each of the two anti-disorder guide wheels 63. The mounting rod 61 passes through the strip pad 62, the strip cover 64 and the table surface of the feeding platform 1, and the upper and lower ends of the mounting rod 61 are positioned by bolts.

[0047] In one possible implementation, the feeding platform 1 is supported by a welded steel frame and has a metal panel on top. N sets of reels 2 and an equal number of guide roller assemblies 5 and anti-disorder devices 6 are installed on the metal panel. The reels 2 are fixed to the metal panel by the reel shaft 21 and the reel bearing seat 23. The other end of the reel shaft 21 is connected to the reel motor 24 by the torque retainer 25. When winding the tape, the reel motor 24 does not rotate, and the torque retainer 25 provides tension to keep the tape taut. When it is necessary to unwind the wound tape, the 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 reel 2.

[0048] In one possible implementation, the torque retainer 25 can also 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.

[0049] In one possible implementation, an engineering plastic plate is also installed 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, which is used to support the superconducting tape and prevent the superconducting tape from sagging too much and causing bending.

[0050] In one possible implementation, the two anti-disorder guide rollers 63, the strip cover 64, and the strip pad 62 of the anti-disorder device 6 confine the strip within a square space to prevent the strip from scattering. One of the anti-disorder guide rollers 63 can be adjusted so that the distance between the two anti-disorder guide rollers 63 is slightly greater than the width of the strip bundle, allowing the strip bundle to pass smoothly without scattering.

[0051] In one possible implementation, each feeding platform has a retainer to keep the strip neat and prevent it from scattering.

[0052] In one possible implementation, a spiral groove 41 is provided on the outer side of the wire harness integration disk 4, a clamping mechanism 7 is provided at the inner end of the spiral groove 41, and a pressure plate 8 is provided on one side of the clamping mechanism 7.

[0053] In one possible implementation, 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 pressure tongue 73 is provided in the clamping groove 72. Several fastening bolts 74 are screwed to the side of the clamping groove 72. The wire harness passes through the clamping groove 72, and the wire harness is fixed by rotating the fastening bolts 74 to squeeze and move the pressure tongue 73.

[0054] In one possible implementation, the rotary table 3 is an existing device that drives the wire harness integration disk 4 to rotate via a motor reducer.

[0055] In one possible implementation, 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 strip bundle (a collection of multiple strips gathered together is called a strip bundle). As the number of turns increases, the length difference will become larger and larger. Therefore, it is necessary to solve the problem of the length difference on both sides during the winding process. Otherwise, the strip will become scattered, resulting in bending damage to the superconducting strip and loss of superconductivity.

[0056] Furthermore, the solution to the length difference between the inner and outer rings is as follows: Since each strip has a certain tension, the strip is always taut during the winding process. This will automatically cause the strips at different positions on the inner and outer rings to slide relative to each other, thereby automatically compensating for the length difference between the inner and outer rings and keeping the strips neat during the winding process.

[0057] In one possible implementation, the starting ends of the strip bundle converge and are fixed to the rotating platform by a clamping mechanism 7. The clamping mechanism 7 clamps the strip bundle by pressing it against the strip with screws. Since the clamping mechanism 7 is higher than the stainless steel frame, a pressure plate 8 is added at a distance from the clamping mechanism 7. The pressure plate 8 is a flat plate, one end of which is fixed to the rotating platform with screws, and the other end presses the strip bundle into the groove.

[0058] In one possible implementation, during the winding process, the operator holds down the strip already in the groove with one hand (to prevent the strip from being pulled out), while the other hand needs to continuously adjust the strip about to be inserted into the groove, adjusting it as it is inserted into the groove.

[0059] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
