Definitions

  • the invention relates to a method for producing a magnet assembly with a wound flat magnetic core, the magnet assembly and a support body for use in this method.
  • Such magnet arrangements have a magnetic core which carries a conductor winding and can have a high quality, which is interesting for a frequency range from 1 kHz to about 20 MHz and above.
  • the magnet arrangements can serve as antenna rods in RFID (Radio Frequency Identification) systems, anti-theft devices, recognition systems, for wireless energy transmission, for example for recharging accumulators, as well as for information transmission.
  • RFID Radio Frequency Identification
  • Typical operating frequencies in these applications are approximately 20 to 150 kHz or 13.5 MHz.
  • a corresponding magnetic core is flat and strip-shaped, wherein the thickness is much smaller than the width and this in turn is much smaller than the length of the magnet arrangement or the magnetic core.
  • Typical thicknesses range from fractions of millimeters to a few millimeters, the width is for example between 2 and 30 millimeters and the length is about 10 to 150 millimeters.
  • Nanocrystalline or amorphous materials have the advantage of high saturation magnetization and, as a laminate, high flexibility and mechanical insensitivity.
  • the winding is carried out as a toroidal coil around the core, with the longitudinal axis of the core and toroid coinciding.
  • the winding numbers are typically 10-1000.
  • Particularly flat cores or magnet arrangements are desired, for example with a total thickness of the magnet arrangement in the range of one to a few millimeters.
  • the minimum achievable thickness of the magnet arrangement is composed of the sum of two winding layers (above and below the magnetic core) and the thickness of the magnet core.
  • the problem arises that a very thin magnetic core with a thin insulated conductor as possible must be tight and tight wound.
  • Dodging on strip-shaped ladder, z. B. flat wire or foil is not possible for a given required winding density and conductor cross-section for lack of space.
  • the insulation of the winding conductor during winding or even later during operation is damaged, in particular in the case of electrically conductive magnetic cores, which leads to short-circuits which severely impair the functioning of the magnet arrangement.
  • Flat magnetic cores which consist of laminated ribbons of amorphous magnetic alloys are, for example, from DE 195 13 607 for various applications, for example, for installation in EC cards, known. From the EP 0 762 535 are also correspondingly flat laminated designs with a Leiterbewicklung known.
  • the object of the invention is therefore to provide a method for producing a magnet arrangement with a flat magnetic core whose width is greater than its height, and with a coil-shaped winding of at least one conductor, in which the magnet assembly without the risk of damage to the winding or the magnetic core to be produced in the flatest possible design.
  • the object is achieved by a method according to claim 1, a magnet assembly according to claim 14 and a support body according to claim 17.
  • a magnetic core with an insulated round wire for example, has a diameter between 0.1 and 0.4 mm wound, the thickness of the magnetic core can be between 0.1 and 1 millimeter.
  • the magnetic core is clamped in a winding machine and rotated about the longitudinal axis for winding. In this case, a certain minimum tensile force is exerted on the winding conductor in order to achieve a tight contact with the magnetic core.
  • it is provided to support the magnetic core by a support body during winding with the conductor and to remove the support body after winding.
  • the support body for example, wound together with the magnetic core and then pulled out of the winding.
  • the parts of the individual turns of the winding projecting beyond the magnet core after withdrawal of the support body are advantageously folded in the longitudinal direction, that is to say in the direction of the coil longitudinal axis or the magnetic core longitudinal axis, against the magnet core with a pivoting movement and fastened there, for example, by means of an adhesive.
  • a support body is advantageously used, which corresponds in width to the dimensions of the magnetic core, wherein the length of the support body may be greater than that of the magnetic core to facilitate a simple clamping in a winding machine. It will be that way, then ensures that during the winding process, the magnetic core is stabilized without the height of the magnet assembly increases. The problem of the extended turns can then be solved as described by folding the windings to the magnetic core.
  • provision may also be made for the supporting body to protrude beyond the magnet core with respect to the width.
  • the support body can then also have a U-shaped contour in cross-section, so that it encloses the magnetic core in a trough-shaped manner on at least one side and thus prevents contact of the winding conductor at least on this side of the magnetic core.
  • the outer contours of the support body may be rounded so that there is no risk of injury to the winding conductor.
  • the support body may also have on the underside facing away from the magnetic core an elevated and extending in the longitudinal direction of the magnetic core web. This ensures increased stability of the arrangement and can be folded or otherwise removed for easier removal of the support body from the finished wound winding, for example, to the support body.
  • the support body after winding and before its removal from the magnetic body by external action with respect to its height and / or width can be reduced. This can be realized, for example, in that the support body is folded or pushed together after winding.
  • the turns either in segments in the same direction or in different directions parallel to the longitudinal axis of the magnetic core folded at this.
  • an adhesive can be applied at the same time to fix the windings or a double-sided adhesive tape can be used to fix the folded turn parts on the magnetic core.
  • a magnet arrangement according to the invention has a flat magnetic core whose width is greater than its height and whose length is substantially greater than its width, and a coil-shaped winding with a winding conductor, the turns of the conductor being at least 30% of the thickness of the conductor Magnet core (corresponding to twice the minimum thickness of the support body) are longer than the smallest possible spiral winding of the magnetic core corresponds and wherein the winding parts per turn on the top and bottom of the magnetic core against each other in the direction of the longitudinal axis of the magnetic core abut against this.
  • the magnetic properties of the arrangement are not affected by the described design of the winding.
  • the magnet assembly according to the invention if the core is a laminate of different only a few microns thick amorphous or nanocrystalline magnetic materials, highly flexible, without this would adversely affect during the manufacturing process. Due to the anisotropy of the laminated core, the change in the shape of the winding also does not practically affect the direction of the magnetization.
  • This arrangement is particularly advantageous when the magnetic core is less than 2 millimeters thick. It is even more advantageous if the magnetic core is less than 1 millimeter thick.
  • the invention further relates to a support body for use in the method described above.
  • the support body can be designed as a so-called coincident construction, for example, consisting of two part bodies, which moves after winding against each other so be that reduce the effective height and / or width of the support body and the support body or its individual parts can be easily removed.
  • the support body can also be provided to produce the support body from a material with so-called temperature memory, such that the support body at a first temperature, when joined together with the magnetic core, takes up more space than at a second temperature. The winding then takes place at the first temperature, then the temperature is changed to the second temperature and pulled out the support body.
  • Figure 1 shows a magnetic core 1, on which a winding 2 is wound. This is done by the magnetic body 1, as indicated by the arrow 3, is rotated about its longitudinal axis. He is to rotatably mounted in two camps 4, 5.
  • a tensile force is exerted on the conductor 6 of the winding 2 in the direction of the arrow F in order to achieve a tight-fitting winding.
  • the magnetic body 1 is simultaneously deformed in the direction of the force F, so that it bends during its rotation in this direction. This damages the stability of the magnetic core and can lead to its destruction.
  • FIG. 2 shows the magnetic body 1, which is supported by a support body 7.
  • the support body 7 consists of two parts, a base body 8 and a connection body 9, whereby the support body after the application of the winding 10 are more easily pulled out of this and the connection body 9 can be separated from the support body.
  • a one-piece design of the support body is also possible, but worse to pull out at longer windings.
  • It can also additional fasteners for the core are provided on the support body, these are not shown in the drawing for the sake of simplicity.
  • the support body 7 is rotatably clamped in bearings at its two ends 11, 12, so that the magnet body 1 and the support body 7 can rotate together about a longitudinal axis 13 for applying the winding 10.
  • FIG. 3 shows a top view of a support body 7 which protrudes slightly beyond the magnetic core 1 with respect to the width B in order to prevent the conductor from contacting the lower edges of the magnetic core during winding.
  • the width of the support body 7 can also coincide exactly with the width of the magnetic core 1 when required.
  • FIG. 4 shows a support body 7 or a part 8 of the support body which has been pulled out of the winding 10 in the direction of the arrow 14 so that parts 15, 16 of turns of the winding 10 now protrude beyond the magnet core 1.
  • FIG. 5 shows that the segments 17, 18 of the winding 10 have been treated differently.
  • the protruding parts of the turns of the segment 17 of the winding 10 are in the direction of the arrow 19, the turns of the segment 18 of the winding 10 are folded in the direction of the arrow 20 to the magnetic core 1 by pivoting and fixed there by means of an adhesive.
  • the various dimensions of the windings, the magnetic core and the support body can be related to each other.
  • the angle ⁇ which include the oblique parts of the turns with the longitudinal axis 13 of the magnetic core, may be less than 70 °.
  • the symmetry axis of each individual turn is no longer parallel to the longitudinal axis of the magnetic core.
  • the effect is, however, justifiable, even for ferrite cores.
  • laminated cores having a shape anisotropy in the direction of the longitudinal axis and material permeabilities of more than 1000 behave particularly advantageously, since in them the magnetization is conducted into the tape layers of the laminate, so that the skew of the windings has virtually no influence on the direction the magnetization has. It is important that the lamination of the laminate along the width and length of the magnetic core extends as shown in Figure 5 rudimentary.
  • FIG. 7 shows a support body, which consists of two part bodies 21, 22, which are assembled wedge-shaped in plan view.
  • the first part body 21 is moved in the direction of the arrow 23 and the second part body 22 in the direction of the arrow 24.
  • they are in the area in which they rest against each other, by means of a web and a groove, as shown in Figure 8, adapted to each other.
  • FIG. 9 Another variant of this is shown in FIG. 9 in a plan view and FIG. 10 in a longitudinal section.
  • the magnetic core 1 is shown in each case together with a first part body 25 and a second part body 26, which also fit together in a wedge shape, but in the longitudinal sectional plane, as shown in Figure 10.
  • These partial bodies can also be pulled apart after the application of the winding in the direction of the arrows 27, 28 to reduce the height of the support body.
  • FIG. 11 shows, in cross-section, a support body 29 which supports the magnetic core 1 for applying the winding. After applying the winding, the temperature of the constellation is changed.
  • the support body 29 is made of a material having a so-called temperature memory, so that the body automatically assumes different shapes at different temperatures.
  • the supporting body 29 then assumes, after the winding and at the second temperature, the shape shown in Figure 12 in cross-section, so that the overall height of the assembly is reduced and the support body 29 can be easily pulled out of the winding in the longitudinal direction of the magnetic core 1.
  • FIG. 13 shows a magnetic core 1 with a two-part support body 30, 31, wherein the first part body 30 of the support body has a U-shape in cross-section, wherein the individual limbs of the U-shape in cross-section in the direction of Width of the magnetic core 1 run. Between the legs of the first part body 30 is a gap in which the second part body 31 is partially immersed.
  • the two partial bodies 30, 31 together have approximately the width of the magnetic core and can be fixed in this constellation against each other, for example by means of a screw.
  • the fixation can be solved and the second part body 31 can be further inserted into the first part body 30, so that the width of the constellation of the support body decreases and this the winding can be easily pulled out.
  • the invention thus provides an easy-to-use method for producing a magnet arrangement, in which the magnetic core itself is stressed as little as possible mechanically during winding, without the quality of the winding suffering therefrom, and in which the magnet arrangement has a minimal volume.
