Definitions

  • the invention relates to a device for non-contact energy and data transmission with two relatively rotatable carriers on which primary and secondary windings of a transformer are arranged.
  • Such a device is used for example for energy and data transmission between two mutually movable components.
  • Such component arrangements can be found in particular in robot applications in which partial angles of rotation between components of a robot of 360 degrees and more are required and data and / or energy transmission between these components is necessary.
  • Another example of a field of application of such a device is the energy and data transmission between the steering shaft and the steering column of a motor vehicle.
  • the cables used in the area of the swivel joints must have a very high degree of flexibility in order to minimize wear and production losses. Therefore, an inductive non-contact energy and data transmission between relatively rotatably mounted parts is advantageous.
  • Out DE 199 14 395 A1 is an inductive transmitter for transmitting measurement data and / or electrical energy between two mutually movable components, in particular between the steering shaft and the steering column of a vehicle, known with a primary and a secondary transmission part.
  • the iron cores each serve for the frequency-selective transmission of the signals, which improves the efficiency of data transmission and reduces the size of the transformer. With the transformer both data signals and signals for electrical energy transmission between the rotating and the stationary part are transmitted.
  • the invention is based on the object to enable an inductive non-contact energy and data transmission between two mutually rotatable components, with the least possible interference of the data transmission is to be achieved by the energy transfer.
  • a device for non-contact power and data transmission with a rotatably mounted on a first carrier primary winding assembly and rotatably mounted on a second carrier secondary winding assembly, wherein the first and second carrier are rotated against each other and wherein the primary and Secondary winding arrangement each having at least one Energywicklung for inductive transmission of electrical energy, wherein primary and secondary winding arrangement each have at least one data winding for inductive data transmission and at least one data winding of the data winding at least one energy binding the energy winding so encloses that a first part of the data winding with the winding sense of the energy winding is wound and a second part of the data winding is wound against the winding sense of the energy winding.
  • the invention is based on the finding that in the case of an arrangement of the data winding and energy winding on a common carrier, an interference of the data winding with the energy winding can be virtually eliminated if the windings of the data winding enclose the energy winding. With such an enclosure, however, the winding sense of the energy winding must be taken into account. If the first part of the data winding is wound with the winding sense of the energy winding, the second part of the data winding must be wound against the winding sense of the energy winding. In this way it is achieved that a voltage induced by the energy winding in the first part of the data winding is compensated by a second voltage component, which is induced by the energy winding in the second part of the data winding.
  • the data winding in relation to the energy winding such that magnetic field strength components generated by the energy winding compensate each other within a surface enclosed by the data winding such that almost no magnetic flux results within the area.
  • the compensation effect can be explained physically by the fact that the voltage induced in a data winding is proportional to the time derivative of the magnetic flux within the area spanning this data winding. If, within the surface, virtually no magnetic flux results due to the desired compensation effect, then no voltage can be induced within the data winding that spans the relevant surface, and thus no interference can be coupled in.
  • the above-described minimization of the magnetic flux within the area spanned by the data winding can be achieved, in particular, by arranging the energy bonding substantially centrally between the first part of the data winding, which is wound with the winding sense of the energy winding and the second one Part of the data winding, which is wound contrary to the winding sense of the energy winding.
  • This achieves that about half of the area enclosed by the data winding is penetrated by a magnetic field strength that is opposite to the field strength that penetrates the other half of the enclosed area.
  • the field strength components of the two surface halves compensate each other and there is almost no magnetic flux on the total surface area. Due to the vanishing resulting magnetic flux no voltage can be induced in the data winding and thus no interference from the energy winding can be coupled into the data winding.
  • a compact size of the device for non-contact power and data transmission can be achieved that primary and secondary winding assembly are each designed as a flat coil.
  • the first and the second carrier are rotationally symmetrical and arranged offset from one another axially and have a common axis of rotation.
  • the first and second carrier are rotatable relative to each other via the common axis of rotation.
  • the primary and secondary winding arrangement in the form of a flat coil is advantageous for minimizing the leakage flux to perform the first and second carrier as a ferrite mirror.
  • Ferrites are ideal as core material for inductive transformers, as they cause only low eddy current losses even at high frequencies due to their low electrical conductivity.
  • the device is intended for mounting in rotatable systems, in particular for automation technology, wherein the first carrier is connected to a stationary part of the system and the second carrier with a rotatable part of the system connected is.
  • a robot having a rotatable gripping arm.
  • a rotation angle range of 0 to 360 ° or even more is required, over which the first carrier must be rotatable relative to the second carrier.
  • the first and second carrier carried out annular are.
  • the propeller shaft can be passed directly through the first and second carrier and thus through the device.
  • the first and second carrier are each divisible into a first and second sub-carrier, wherein the first and second sub-carrier in particular each having a semicircular recess. Due to the divisibility of the device, the transformer formed by the first and second carrier and the associated primary and secondary winding assemblies can be mounted on a propeller shaft without having to separate this propeller shaft. As a result, the installation and cost is significantly reduced. Due to the semicircular recesses, the sub-carriers can be very easily mounted around a propeller shaft.
  • the energy winding and the data winding each have a first and a second, in particular series-connected coil, wherein the first coil on the first sub-carrier and the second coil are arranged on the second sub-carrier.
  • Particularly advantageous in such a winding arrangement is that even with a large number of turns in the first and second coil only a cable connection between the two coils and thus between the two sub-carriers for the energy winding and one for the data winding are necessary.
  • the divisibility of the energy and data transmission can be achieved in that at least a first turn of the first coil within the first subcarrier and at least one second turn of the second coil within the second subcarrier are closed such that they each have an inner Winding part with an inner radius and a outer winding part having an outer radius which is greater than the inner radius, have.
  • the number of turns of the coils of a subcarrier is freely selectable and an optimal transmission behavior adjustable (separately for the energy and data transmission).
  • FIG. 1 shows a sectional view of a first coil arrangement for contactless energy and data transmission comprising a first carrier 5, on which a primary winding assembly is arranged rotationally fixed, and a second carrier 6, on which a secondary winding assembly 2 is arranged rotationally fixed.
  • the flat coil arrangement shown is used, for example, for inductive energy and data transmission in a robot with a rotatable joint.
  • the first carrier 5 is connected to a fixed part of the robot and the second carrier 6 is mounted with a rotatable relative to the first part of the robot Part connected.
  • the first and second beams 5, 6 are made annular and mounted on the pivot shaft of the robot.
  • the primary winding arrangement 1 has a primary-side energy winding 3a, which is supplied, for example, by a power converter and generates a field which couples into a secondary-side energy winding 3b, which is a component of the secondary winding arrangement 2. In this way, it is possible to transfer energy via the rotary joint of the robot, without requiring a wear-prone cable connection.
  • primary winding arrangement 1 has a primary-side data winding 4a and secondary winding arrangement has a secondary-side data winding 4b, wherein a magnetic field generated by the primary-side data winding 4a couples into the secondary-side data winding 4b.
  • the first and second carrier 5, 6 and the primary winding assembly 1 and the secondary winding assembly 2 are rotationally symmetrical, axially offset and have a common axis of rotation 7. Such an embodiment is particularly advantageous for mounting on a pivot shaft.
  • the first and second carrier 5, 6 are furthermore of annular design and have a saving in the region of the axis of rotation 7. The saving is used to carry out the pivot shaft of the robot.
  • the winding arrangements show that a conductor of the primary-side energy winding 3a is surrounded on both sides by a conductor of the primary-side data winding 4a. This, as well as the following consideration applies analogously to the secondary side, since the basic structure of primary and secondary winding assembly 1,2 is the same.
  • Each conductor of the primary-side energy winding 3a is arranged substantially centrally between the two conductors of the primary-side data winding 4a.
  • the winding sense of the primary-side data winding 4a is oriented on one side of the conductor of the primary-side energy winding 3a opposite to the winding sense of the primary-side data winding 4a on the other side of the primary-side energy winding 3a.
  • FIG. 2 shows a plan view of the first coil assembly for contactless power and data transmission. Since the winding concepts of the primary and secondary winding assemblies are generally not different, only one side of the transformer is shown, which can represent both the primary-side winding arrangement and the secondary-side winding arrangement.
  • FIG. 2 shows that a turn of the energy winding 3 is surrounded on both sides by a conductor of a data winding of the data winding 4. In the case of a data winding through which the current flows, the direction of the current within the data link adjacent to the energy connection is in each case opposite. By this type of winding, a compensation effect of the induced voltages is achieved within the windung, based on the FIG. 3 should be clarified.
  • FIG. 3 shows an energy conductor 10 and an integration path 11 for an induced electric field strength.
  • the integration path 11 Through the integration path 11, a rectangular area is spanned, in which the energy conductor piece 10 forms an axis of symmetry.
  • a current direction is indicated by an arrow.
  • Such a current direction generates a magnetic field strength which is directed into the drawing plane to the right of the energy conductor piece 10 and protrudes to the left of the energy conductor piece 10 from the plane of the drawing.
  • the field strength components on the right of the energy conductor piece 10 thus compensate with those on the left of the energy conductor piece 10, so that no magnetic flux results within the area spanned by the integration path 11. It follows that the induced voltage within a conductor loop indicated by the integration path 11 is just zero.
  • the arrangement of the integration path 11 with respect to the energy conductor piece 10 also characterizes the arrangement of the data winding with respect to the energy winding in the 1 and FIG.
  • FIG. 4 shows a second flat coil arrangement with two energy turns of a Energy windlung 3.
  • a data winding 4 with respect to the Energywicklung 3 so wound, that in each case a conductor of a data winding of the data winding 4 with and a conductor of the data winding opposite to the winding sense of the energy winding 3 is arranged.
  • two turns of the energy winding 3 are between two conductors of the data winding.
  • the desired compensation effect of the magnetic field strength within the data winding 4 is achieved.
  • FIG. 5 shows a third flat coil arrangement with two energy connections of a Energy winding 3.
  • the number of turns of a data winding 4, as already in the in FIG. 4 considered arrangement one.
  • the data winding 4 is wound in such a way that only one energy bond of the energy winding 3 is arranged between a forward and a return conductor of a data winding of the data winding 4.
  • the desired compensation effect of the induced electric field strength, which is caused by the magnetic field strength generated by the energy winding 3 is achieved.
  • FIG. 6 shows a fourth flat coil arrangement with two data turns of a data winding 4.
  • the number of turns of a Energy winding 3 one.
  • the illustrated winding of the energy winding 3 is surrounded on both sides by two conductors of the data winding 4.
  • the field strength components induced by the energy winding 3 compensate each other within the data windings Data winding 4.
  • an interference of the data winding 4 by the energy winding 3 can be largely excluded.
  • FIG. 7 shows a divisible flat coil assembly, which is provided for inductive contactless power and data transmission.
  • a flat coil arrangement is arranged, for example, on a divisible annular support. With such a carrier, the flat coil arrangement shown can be mounted very easily on a pivot shaft, in particular of a robot. Due to the divisibility of the flat coil arrangement of the transformer can be mounted directly on the propeller shaft without having to dismantle it before.
  • the illustrated flat coil arrangement has a first coil arrangement 8 comprising an energy winding 3 and a data winding 4 and a second coil arrangement 9, which likewise has an energy winding 3 and a data winding 4.
  • the first and second coil assembly 8, 9 is connected to each other only by a cable connection for the energy winding 3 and a cable connection for the data winding 4. Even with a much higher number of windings for the first and second coil arrangement 8,9 only one connection would be necessary for the data and energy winding 3,4.
  • the divisible flat coil arrangement is characterized in that the first coil arrangement 8 is connected in series with the second coil arrangement 9, the coil arrangements 8, 9 again being wound in such a way that at least one data winding of the data winding 4 encloses at least one energy gap of the energy winding 3 in such a way, that a first part of the data winding is wound with the winding sense of the energy winding 3 and a second part of the data winding is wound against the winding sense of the energy winding 3.
  • All flat coil arrangements shown in the figures have the advantage that 4 separate windings are provided for the energy winding 3 and the data winding.
  • the energy winding 3 for an optimal inductive Energy transmission between the primary winding arrangement and the secondary winding arrangement are optimized and the data winding 4 for optimum inductive data transmission between the first and second carrier or between the primary winding arrangement and the secondary winding arrangement.
  • the inventive arrangement of the data winding 4 with respect to the energy winding 3 that the magnetic field of the energy winding 3 induces almost no voltage within the data windings of the data winding 4 and thus exerts no interference on the data transmission.
