Description

Technical Field

[0001] The invention relates to a wire coil feed device for moving a plurality of wire coils in the production of coil windings.

[0002] The invention relates to the technical field of producing coil windings for producing stators and rotors of electric motors. In this case, a plurality of wires are wound into a coil mat. Background Art

[0003] The word stator comes from the Latin word "stare", which means stationary. The stationary part of an electric motor is called the stator or stator. The rotating part of an electric motor is called the rotor or armature.

[0004] The rotor usually consists of a motor shaft, an armature made of iron sheets, armature coils with different windings and slip rings for power transmission.

[0005] There are many different types of electric motors. The most important difference between the various types is the power supply. Here, it is determined during the design whether the motor must be powered by direct current, alternating current or three-phase current.

[0006] However, the required magnetic field is also generated in different ways in corresponding motors. In addition to strong permanent magnets, electromagnets can also be used, depending on the application. For this purpose, in the simplest case, a coil made of copper wire is wound around an iron core made of sheet metal to generate the required magnetic field.

[0007] Winding technology mainly determines the performance of electromechanical components with windings (such as stators and rotors). The performance includes dielectric strength, quality factor, required size for a certain power or magnetic force or magnetic scattering field.

[0008] In the known method for producing coil windings for stators and rotors, the wires are fed to the winding machine in parallel. During the winding process, the wires cross and phase jumps occur. To cross the wires, a first wire is placed in the groove of a second wire and the second wire is placed in the groove of the first wire.

[0009] The number of phase jumps in the winding is limited. The wire is guided from its initial position to the phase jump and is loaded obliquely. In addition, the wires rub against each other. This can lead to damage to the wire insulation and thus to process interruptions. In addition, due to the large amount of wire movement caused by braking and tensioning the wire, the wire course of the individual wire coils cannot be reliably controlled. Summary of the invention

[0010] The object of the present invention is to provide a wire coil supply device which overcomes the disadvantages of the prior art and enables the production of coil windings with a reduced number of phase jumps. The object of the present invention is also to provide a method for producing coil windings which overcomes the disadvantages of the prior art and allows the wire movement during the winding process to be reduced.

[0011] This object is achieved by a wire coil feed device for moving a plurality of wire coils in the production of coil windings having the features of the independent claim. Advantageous embodiments form the subject matter of the associated dependent claims.

[0012] The invention comprises a wire coil feed device for moving a plurality of wire coils in the production of coil windings, the wire coil feed device comprising at least two belts with guide rails. Coil carriers can be arranged accordingly at the guide rails. A connecting rail is arranged between the two belts, on which the coil carriers can move between the guide rails of the belts. In addition, the wire coil feed device comprises at least one parking rail, from which the coil carrier can be moved to the parking rail, so that another coil carrier arranged on another guide rail can pass. This enables the coil carriers to pass each other, and therefore it is not necessary to feed the wire crosswise into the winding process.

[0013] In an advantageous aspect, the connecting rail is arranged perpendicular to the belts. This allows the coil carrier to be transferred between the two belts.

[0014] It is particularly advantageous if the two strips with the guide rails are arranged parallel to one another. Here, the coil carrier can be easily moved between the guide rails and the connecting rails to take up different positions.

[0015] According to a preferred aspect, the two belts with guide rails are arranged at a predetermined angle to each other. This achieves a compact structure.

[0016] According to an advantageous aspect, two belts with guide rails are arranged on a carrier unit. The carrier unit comprises a drive which is designed to move the carrier unit from a horizontal position into an inclined position. As a result, a plurality of coil carriers can be arranged in one layer in a space-saving manner and can be oriented in an optimal manner for the winding process by means of the inclined position.

[0017] Advantageously, at least two carrying units are arranged radially and pivotably at a rotation point. This allows a plurality of carrying units to be arranged in a circle to form a wire coil mobile magazine.

[0018] It has proven to be advantageous if the wire coil supply device also includes a coil carrier. The coil carrier includes rollers so that it can roll along the connecting rail and along the parking rail. This allows the coil carrier to be easily moved along the connecting rail and along the parking rail and can be overtaken by other coil carriers.

[0019] According to a preferred aspect, a wire coil is arranged on the coil carrier. The wire coil comprises a wire guide section, which is configured to convey the wire to the wire winding unit. This allows the wire to be wound into the coil winding without phase jumps.

[0020] Advantageously, the wire guide section comprises an adjustment unit for orienting the wire guide section relative to the wire winding unit and a wire braking unit for regulating the speed of the wire. This allows the wire to run smoothly and the winding process can be reliably controlled as a whole.

[0021] The invention also comprises a method for producing a coil winding on a stator and / or a rotor, the method comprising the following steps:

[0022] Provide wire coil supply device;

[0023] · moving the first coil carrier from the guide rail to the parking rail;

[0024] Move the second coil carrier along the guide rail so that the second coil carrier exceeds the first coil carrier;

[0025] Move the first coil carrier from the parking rail to the guide rail.

[0026] Since the coil carriers can "overtake" one another, coil windings can be produced with a reduced number of phase jumps. BRIEF DESCRIPTION OF THE DRAWINGS
