Definitions
- the invention relates to a method for producing a winding of a coil according to the preamble of patent claim 1 .
- the object of the invention is therefore to provide a method for winding a coil which improves the reproducibility of the operating parameters and in particular which reduces the material consumption in the production of electrical windings of coils.
- a flyer is understood to be a very rapidly rotating disk or a rapidly rotating arm for producing wire windings of coils.
- Other types of guides are also conceivable when winding wire onto spools.
- a coil comprises a winding made of a wire.
- a winding comprises a large number of windings in the form of one circumnavigation of the coil core, e.g. B. of the stator tooth or rotor tooth with a wire loop.
- the invention provides a method for producing a winding of a coil around a component, z. B. a stator tooth or rotor tooth of an electric motor, wherein to produce the winding at least one wire is guided over at least one arm or the like encircling the component in a rotational movement in such a way that the wire is wound in successive turns is wound around the component, with at least one image acquisition device and/or at least one computer unit providing information about the course of windings that have already been wound, with the arm being dynamically controlled in a type of movement that differs from the encircling rotational movement in such a way that the current winding applied with the movement is opposite to one already previously applied adjacent windings optimized determined winding course follows.
- a degree of freedom for minimizing the wire length is created.
- This degree of freedom is the guidance of the flyer arms. These are not guided according to a fixed pattern, for example in the manner of being guided back and forth, but in such a way that the falling of the winding is detected by means of an image acquisition device and the movement of the flyer arms is controlled dynamically. This allows the wire to take the shortest route around the tooth of the stator or rotor.
- the wire can be wound very quickly, which can reduce the costs of a manufacturing process, for example by reducing the corresponding throughput time.
- material can be saved in the manufacturing process, which can also lead to a reduction in costs.
- the winding to be newly laid is preferably inferred from the winding that has already been wound. In the case of only a small deviation from the desired pattern, which would have to be corrected due to the high time requirement, after a predetermined pattern wound, which can reduce the overall time required in the manufacture of winding the coil.
- an optimized wire length can reduce the electrical losses when operating the winding of the coil, for example within an electric motor, and the motor can thus be used more efficiently and cost-effectively.
- the operational reliability of the motor can be increased, since it is necessary to have knowledge of the precise parameters of the electric motor, in particular the coils, in order to determine the rotor position in the case of methods without a rotary encoder.
- the actual circumference of individual windings is a variable that can be determined quickly using the image acquisition device. From the knowledge of the extent, the wire length already used can be quickly calculated using simple formulas, which can reduce the time required for the computing power of the controller and thus the manufacturing process.
- the optimized winding course runs as the course of the current winding with the smallest possible extent compared to the neighboring windings.
- the optimized course of the windings runs as a course with the lowest possible number of radial stacks of windings compared to the neighboring windings.
- the optimized winding course is weighted as a course with a possible jump distance to the previous winding, compared to the neighboring windings.
- the computer unit includes a memory unit and stores information about windings of previously manufactured coils, namely winding scenarios of finished windings, with the information being obtained from the control of the arm and/or from the image acquisition device and in particular further data in the form of the physical parameters obtained , such as B. Wire length, resistance, magnetic flux of the wound coil, etc. recorded and stored assigned to the winding scenario.
- the data that has accumulated in the course of the manufacturing process of coils that have already been manufactured can flow into the manufacturing process of coils that are to be manufactured in the future.
- the decision-making process for the winding courses in the manufacturing process can be continuously improved with the manufacture of each additional coil.
- the data from the coils that have already been manufactured flow into the decision-making process, in particular of a relevant artificial intelligence, after the end of their manufacturing process.
- the manufacturing process of the coils to be manufactured in the future can be improved as a result.
- the calculation of the determined winding course which is optimized compared to neighboring windings that have already been applied beforehand, takes place in real time, preferably for each subsequent winding immediately before it is applied.
- the computer unit includes an artificial intelligence, which weights and influences the determined winding profile, which is optimized compared to neighboring windings that have already been applied.
- an artificial intelligence which weights and influences the determined winding profile, which is optimized compared to neighboring windings that have already been applied.
- the winding can be accelerated in such a way that time-consuming calculations for measuring the wire runs are reduced and replaced by a learned pattern for the winding.
- a new turn to be laid is always inferred from a turn that has already been wound. If there is a deviation from a predetermined winding pattern, this deviation is corrected in favor of saving material. However, if the correction would take up too much time, the winding will continue according to the specified winding pattern.
- Figure 1 is a schematic sectional view of the winding of a stator tooth or rotor tooth
- FIG. 2 shows a flowchart in which the sequence of the method according to the invention is shown.
- FIG. 1 schematically shows a stator tooth or rotor tooth ( 4 ) around which a wire is laid to produce a winding.
- the turns ( 3 ) already wound are followed by a new turn ( 1 ) to be laid .
- a flyer arm (not shown) whose movement is controlled ensures that the new winding (1) to be laid follows a relative movement (2) in such a way that it comes to rest at one point on the tooth, despite the somewhat statistical "wild" winding technique , in favor of a minimized wire length and a fast manufacturing process, is optimized
- the winding to be laid ( 1 ) as well as the already wound windings ( 3 ) of the coil are laid down by means of an image acquisition device (not shown) and evaluated.
- the optimal course of the wire at any given point in time is calculated with the help of an artificial intelligence. This uses measurement data, for example with regard to the wire resistance of coils that have already been wound, in order to learn dynamically and improve your decisions .
- FIG. 2 A flow chart is shown in FIG. 2, on the basis of which the method according to the invention is explained.
- an image acquisition device records the course of the wire of windings that have already been wound in the area adjacent to a winding that is to be newly laid. (6) This is followed by an evaluation of an image from the image acquisition device and/or of data on windings that have already been wound. This creates knowledge about the actual circumference of the windings (3) already wound (shown in FIG. 1) in the neighboring area of a winding (2) to be newly laid (shown in FIG. 1).
