Description

The invention relates to a device for winding a wire which can be used, for example, as an air-core coil or as part of an inductive component, in particular as the winding of a transformer.

To manufacture inductive components, for example an air-core coil or a transformer, it is necessary to deform a wire accordingly. For example, to produce an air core coil, the wire must be wound in a helical shape. To manufacture a transformer, it is necessary to wrap the wire around one leg of the transformer. If the transformer has a closed core, an automated, direct winding of the closed core is a particular challenge.

Up to a certain ratio of wire cross-section, spiral winding diameter, number of turns and core cross-section, it is possible to a certain extent to "turn" preformed air coils onto a closed core of a transformer. The helical air core coil, which resembles a tension spring, has to be spread apart so that the core cross-section can be overcome. During this generally very complex and time-consuming process, however, high mechanical forces act on the core to be wound. By spreading the "tension spring" to the "compression spring", the possible degree of filling of a closed core is inevitably limited or the "tension spring" creates permanent mechanical stresses. The ones commonly used for a transformer Ferrite core materials are, however, very sensitive to the effects of mechanical stresses.

It is particularly difficult to manufacture transformers that have a closed core and in which flat wires with a rectangular cross-section (rectangular wires) are used for the winding instead of round wires. This type of transformer enables currents with high amperage to be carried with high inductance of the component due to the high number of turns that can be achieved. The application of a rectangular or flat wire to a closed core can usually no longer be carried out in an automated manner and is therefore generally very time-consuming.

The pamphlets US 2009/065623 A1 , JP 2004-327461 A , U.S. 5,331,729 A and JP 2004-158653 A describe devices and methods for winding a coil around a magnetic core.

It is desirable to specify a device for winding a wire with which it is possible to automatically wind a wire, in particular a rectangular or flat wire, as an air-core coil or to wind it around a closed core of a transformer. Furthermore, a method for winding a wire is to be specified with which it is possible to automatically wind a wire, in particular a rectangular or flat wire, as an air-core coil or to wind it around a closed core of a transformer. The device and the method can also be used to wind a round wire.

In claim 1 such a device is for Winding a wire indicated. The device comprises a feed device for displacing the wire, a shaping device and a pitch transmitter device for bending the wire. In particular, the shaping device is used to bend the wire in one plane and the pitch transmitter device for bending the wire with a slope out of the plane. For example, the pitch transmitter device is arranged behind the shaping device. The pitch generating device can also be integrated into the shaping device, so that the wire also experiences a pitch during circular bending in the shaping device. The shaping device and the pitch transmitter device are arranged in such a way that the wire is introduced into the shaping device and the pitch transmitter device when it is displaced by the feed device. The shaping device and the pitch transmitter device are designed in such a way that the wire is bent helically during displacement in the shaping device and the pitch transmitter device.

In claim 9 a method for winding a wire is specified. The method provides for the provision of a device, in particular the device specified above, for winding the wire. The wire is displaced in the device in such a way that the wire is fed to a shaping device and a pitch transmitter device. When the wire is passed through the shaping device and the pitch transmitter device, the wire is bent in a helical shape. For example, the wire is bent in the plane when it is passed through the shaping device and bent out of the plane with an incline when it is passed through the incline transmitter device.
By means of the specified device or the specified method, almost any cross-sections, preferably thick and therefore very stiff cross-sections, of a wire, in particular a rectangular or flat wire, can be applied very quickly and directly to closed core cross-sections be wound up automatically. The compressed "compression spring" of the winding is retained. The core can be wound almost completely without mechanical stresses being generated in the winding direction and thus with almost no mechanical forces acting on the core.

According to a possible embodiment, the device for winding the wire can contain a guide device for guiding the wire in the plane, the guide device having a straight course in the plane. The wire is placed in the guide device and, by means of the feed device, is pushed into the shaping device which is arranged behind the guide device in the feed direction of the wire. The feed device can be designed, for example, as an eccentric lifting press. The device thus provides a type of “push wire technique” with which very high push forces can be introduced onto the wire guided in the guide device and the shaping device.

The shaping device can be designed as a recess in a plate. The wire can then be bent in the plane of the plate by the deformation device. The shaping device has a bottom surface for supporting the wire and a curved side wall. When the wire is moved from the guide device into the shaping device, the wire is guided along the curved side wall, resting on the bottom surface. The side wall can be bent in a semicircle so that the wire is bent in a circle. The wire is bent out of the plane of the plate by the pitch transmitter device, so that a helical turn of the wire is created from the circular bend. The shape of the wire can also be called "helical" or "spiral" in the sense of a cylindrical spiral.

The device is particularly suitable for bending a flat wire, the flat wire resting with its larger side surface on the bottom surface of the forming device and with its smaller side surface resting on the side wall of the forming device. In order to prevent the wire from tipping over in the shaping device, the side of the recess which is opposite the bottom surface and which is open can be covered by a sliding cover device. This special shape prevents the wire from tipping over when it is bent. The incline sensor device causes the wire to incline, so that after one turn it exceeds its own height and is bent over a section of the wire lying underneath.

The device can have a receiving device for positioning a core, in particular a closed core, of an inductive component, for example a transformer. The shaping device and the pitch transmitter device are arranged around the receiving device in such a way that the wire can be wound helically around a leg of the closed core when it is moved by the shaping device and the pitch transmitter device, without the sensitive lacquer of the wire, for example an enamelled copper wire, or the insulation coating of the core to damage. An otherwise customary winding mandrel is not required. By means of the device, flat or rectangular wires with a width of, for example, 5 mm and a thickness of 1 mm to 2 mm can be bent helically as an air-core coil or helically around one Bend the legs of a closed frame core of a transformer.

When bending flat or rectangular wires with a wire thickness of more than 1.8 mm, an end section of the wire can be pre-bent by a pre-bending device of the device. For this purpose, the wire is clamped in the feed device in such a way that the end section of the wire to be bent protrudes from the device on the side on which the guide device or the shaping device is arranged. By means of the pre-bending device, the end section of the wire is bent in such a way that the wire can then be inserted into the upwardly open depression of the forming device. The further bending of the wire takes place, as described above, in an automated manner by moving the wire through the shaping device and the pitch transmitter device.

According to an illustrative example, an inductive component is specified. The component is preferably produced by the method described above. In particular, the wire is wound circularly with a pitch, i.e., helically.

In an illustrative example, the winding of the wire is designed to be compressed. In the case of a compressed winding, adjacent turns are tight against one another. In particular, the winding is designed without gaps or almost without gaps, so that adjacent turns are in direct contact with one another. For example, the pitch of the helical winding is in the range of the wire thickness. In this way, a particularly high degree of filling of the winding can be achieved.

The inductive component can have a core, in particular a ferrite core. The wire can be wrapped directly around the core. In particular, in this case the wire is not wound around a bobbin made of plastic. In one embodiment, the core has a closed shape. The inductive component can also be designed as an air-core coil.

The wire can be designed as a rectangular or flat wire, for example. Alternatively, it can also be a round wire.

In an illustrative example, the core has, in cross section, an outer circumference that is not circular. In particular, the core can have edges. For example, the core has corners in cross section. In particular, the core can have an outer circumferential line in the form of a polygon.

The invention is explained in more detail below with reference to figures which show embodiments of the present invention.

Figure 1 shows an embodiment of a device 1 for winding a wire 2, which by means of the device 1 can be wound helically as an air coil or around a leg of a closed frame core 3 of an inductive component 4, for example a transformer. By means of the device 1, in particular two parallel wires 2 can be wound around two legs of a closed frame core 3 at the same time.

The device 1 comprises a feed device 10 for moving the wire in a guide device 50 for guiding the wire 2. The feed device 10 has a carriage 11 which is movably arranged on a rail 100. In the embodiment of Figure 1 the device 1 comprises two carriages 11 which are arranged on the rail 100 so as to be displaceable in the horizontal direction. A plate 12 of the feed device is located above the carriage 11 and has at least one guide 13 on its upper side for guiding at least one wire 2. The guide 13 can be designed as a recess in the plate 12. For parallel guidance of the in Figure 1 two wires 2 shown can, as in the case of the in Figure 1 embodiment shown of the device 1 for winding the wire, two guides 13 can be arranged in parallel in the plate 12.

To cover the upwardly open guide 13 in the plate 12, a cover plate 15 can be arranged at least partially on the plate 12. The cover plate 15 can be pressed onto the plate 12 by means of a press 14, so that the open side of the guide 13 is covered by the cover plate 15 and the wire 2 is clamped in the guide 13. To press the cover plate 15 onto the guide 13, a punch 16 is provided above the press 14, which presses the cover plate 15 onto the plate 12 with the guide 13. The plate 12, the cover plate 15 and the punch 17 can be moved back and forth with the movement of the carriages 11 in the horizontal displacement direction of the wire shown by the arrows on the plate 12.

A drive unit 110 is provided for moving the feed device 10. During the forward movement of the wire 2 in the direction of the frame core 3, the wire 2 is pressed firmly in the guide 13 by means of the cover plate 15 and is thus displaced along the guide device 50. The press then lifts the cover plate 15 so that the wire is no longer clamped in the guide 13 of the plate 12. The carriage 11 then moves the plate 12 back into the starting position. The wire feed process is then repeated.

The Figures 2 and 3 show a front area of the device 1 with a guide device 50 for guiding the wires 2 in an enlarged view. The guide device 50 is arranged as a recess in a plate 80. The guide device 50 has a straight course in a plane E of the plate 80. How with the Figures 1 , 2 and 3 As becomes clear, the device 1 has, in addition to the feed device 10 and the guide device 50, a shaping device 20 for bending the wire 2 in the plane E and a pitch transmitter device 30 for bending the wire 2 with a pitch out of the plane E.

The shaping device 20 and the pitch transmitter device 30 are designed in such a way that when the wire 2 is moved by the feed device 10, it is first displaced in the guide device 50 in the longitudinal direction and then introduced into the shaping device 20 and the pitch transmitter device 30. The shaping device 20 and the pitch transmitter device 30 are designed in such a way that the wire 2 is bent helically when it is moved in the shaping device 20 and the pitch transmitter device 30.

The shaping device 20 and the guide device 50 can be designed as part of the plate 80 common to them. The shaping device 20 can have a depression 23 in the plate 80, the depression having a curved course in the plane E of the plate. The recess can be curved, for example, in the shape of a segment of a circle, in particular in a semicircle. The shaping device 20 can have a bottom surface 21 for supporting the wire 2 and at least one side wall 22. The at least one side wall 22 has the curved course. The conversion device 20 is thus designed in such a way that the wire 2 is bent circularly along the side wall 22 when it is moved in the shaping device 20.

The guide device 50 can have a recess 53 in the plate 80, which has a straight course in the plane E of the plate and opens into the recess 23 of the shaping device 20. The guide device 50 has a bottom surface 51 and a side wall 52, which are arranged at right angles to one another and thus form the recess 53 within the plate 80.

The shaping device 20 and the guide device 50 are designed in particular to guide a rectangular or flat wire. A rectangular or flat wire is to be understood as a wire with a rectangular cross section, which has a larger and a smaller side surface, the side surfaces being arranged at right angles to one another. In the Figures 1 to 3 the wire 2 is designed as a flat or rectangular wire with a larger side surface S2a and a smaller side surface S2b.

When the wire is displaced in the guide device 50, the flat or rectangular wire 2 with the larger side surface S2a rests on the bottom surface 51 of the guide device 50. The smaller side surface S2b of the flat or rectangular wire 2 rests on the side wall 52 of the guide device 50. The shaping device 20 following the guide device 50 in the exemplary embodiment shown is designed in such a way that the flat or rectangular wire 2 with the larger one when guiding and bending in the shaping device 20 Side surface S2a rests on the bottom surface 21 of the deformation device and the smaller side surface S2b rests on the side wall 22 of the deformation device.

When the wire 2 is bent in the shaping device 20, the outer area of the wire, which rests closer than an inner area of the wire to the side wall 22 of the shaping device 20, is stretched, while the inner area of the wire is compressed when it is bent. The shaping device 20 is open on the side opposite the bottom surface 21. In order to prevent the flat or rectangular wire from tipping over in the shaping device 20 due to the stresses occurring in the material of the wire 2 during bending, the device 1 can comprise a displaceable cover device 40.

The cover device 40 can be arranged displaceably on the plate 80. The cover device 40 can be displaced on the plate 80 in such a way that the guide device 50 is completely covered and the shaping device 20 is at least partially covered by the cover device 40. In the embodiment of Figures 2 and 3 For the sake of better illustration, only one cover device 40 is shown, which completely covers the depressions of the rear guide device 50 and of the rear deformation device 20 partially.

The cover device 40 can be designed in the form of a plate which is arranged displaceably on the plate 80. For this purpose, the cover device 40 can be displaced along the two recesses 41 transversely to the longitudinal direction of the wire 2 and thus transversely to the longitudinal direction of the guide device 50 on the plate 80. Before the wire by means of the feed device 10 is introduced into the shaping device 20 by the guide device 50, the displaceable cover device 40 is displaced in such a way that the guide device 50 is completely covered and the shaping device 20 is partially covered by the cover device 40. As a result, the front area AB of the shaping device 20, delimited by a dashed line in FIG. 3, with the portion of the wire lying therein is covered by the covering device.

The plate of the covering device 40 has a semicircular recess 42 above the area AB of the shaping device 20. At the lower end of the semicircular recess, the cover device has a thin plate 43 made of a hardened material. This plate 43 can be only a few tenths of a millimeter thick, for example. When the cover device is displaced, the thin plate 43 arranged at the lower end of the recess 42 covers the wire 2 guided in the recess of the shaping device. When the wire runs into the forming device, the thin plate 43 prevents the wire from jumping out or tipping over in the forming device 20 located in the shaping device 20, are arranged. The upper layer of the wire lies over the plate 43, while the lower layer of the wire is guided under the plate 43 in the forming device. The lower layer and the upper layer of the wire winding arranged above it are separated from one another by the thin plate 43 during the winding process.

In the case of the Figures 1 to 3 The illustrated embodiment of the device 1 for bending the wire is the guide device 50 and thus also the plate 80 are arranged behind the feed device 10 in the feed direction of the wire 2. The shaping device 20 is arranged behind the guide device 50 in the feed direction of the wire, so that the wire 2 is pushed into the shaping device 20 when it is displaced out of the guide device 50. The pitch transmitter device 30 can be arranged behind the shaping device 20, so that the wire 2 is guided to the pitch transmitter device 30 when it is moved after the shaping in the shaping device 20. The pitch transmitter device 30 can also be integrated into the shaping device. In this embodiment, the bottom surface 21 of the shaping device rises in the horizontal direction, so that the wire also experiences an incline when it is bent circularly in the shaping device.

In the case of the Figures 1 to 3 The embodiment of the device 1 shown in the figure, the slope transmitter device 30 is arranged behind the shaping device 20. The pitch transmitter device 30 can, for example, have an inclined plate for generating the pitch of the wire. The slope of the plate can be adjustable depending on the pitch of the wire. Figure 4 shows the wire 2 guided in the guide device 50 and the shaping device 20, which is wound around the leg 3, shown in abbreviated form, of the inductive component 4 and the inclination sensor 30. In the case of the in FIG Figure 4 In the illustrated embodiment, the pitch sensor 30 is designed as a ball pin. The pitch sensor has, for example, a cylindrical body with a spherical bulge 31 at its upper end. The incline sensor is arranged on the plate 80 or can be sunk into the plate 80.

Depending on the incline, the incline sensor can be lifted out of the plane E of the plate 80. When the wire 2 is wound, the wire runs onto the spherical arch 31 and, due to its spherical shape, has a pitch that is necessary to produce the actual helical winding of the wire and thus more than one turn of the wire. To bend the wire out of the plane E of the plate 80, the incline sensor can be raised, for example, according to the desired incline, as soon as the wire has slid onto the spherical arch. After the wire has been pushed over the inclined plate or the spherical curvature 31 of the inclination device, the wire is bent out of plane E and can be placed over the section of the wire underneath, which is simultaneously introduced into the forming device. This creates the helical winding of the wire.

In order to wind the wire around a leg of the closed frame core 3, the device 1 has a receiving device 60 for positioning the core 3 of the inductive component 4. The forming device 20 and the pitch transmitter device 30 are arranged around the receiving device 60 in such a way that the wire 2 is wound helically around the leg of the core 3 of the inductive component when the core 3 is positioned in the receiving device 60 and the wire 2 through the forming device 20 and the incline sensor device 30 is guided.

The bending or winding of the wire 2 by means of the device 1 is explained in more detail below. For the sake of simplicity, the method for winding a wire is described for only one wire 2. However, as explained above, the device can also use two wires at the same time be wrapped around two different legs of a closed frame core.

To insert the wire 2 into the feed device 10, the cover plate 15 is first lifted from the plate 12 so that the wire 2 can be inserted into the guide 13 and pushed through the guide device 50 to the start of the shaping device 20. The cover plate 15 is then pressed onto the plate 12 by means of the press 14 and the punch 16, so that the wire 2 is clamped within the guide 13.

By means of the drive unit 110, the carriages 11 and thus the plate 12 are displaced in the direction of the arrow, so that the front end of the wire is pushed into the shaping device 20 by the guide device 50. When the wire 2 is displaced, the front section of the wire, which is guided through the shaping device 20, is bent in a semicircle in the plane E of the plate 80.

To push the wire further forwards, the cover plate 15 is raised by the punch 16 and the press 14 and the carriages 11 with the plate 12 fastened thereon are raised against the position shown in FIG Figure 1 direction shown by the arrow. Due to the bending of the front end of the wire, the wire is fixed and is not pushed back with the movement of the plate 12 and the carriage 11. To advance the wire further, the cover plate 15 is pressed again onto the plate 12 so that the wire is clamped in the guide 13 again. The plate 12 is then moved forward again through the carriage 11, as a result of which the wire 2 is pushed further into the shaping device 20 and is bent into a semicircle there. The front end of the The wire now reaches the pitch transmitter device 30 and is bent out of the plane E of the plate 80 as it continues through the pitch transmitter device 30. By pushing the wire further forward, the wire can ultimately be helical by means of the device, as in FIG Figures 1 to 3 shown to be bent.

The method described for bending the wire by means of the device 1 can be carried out, for example, for bending a wire with a width of 5 mm and a thickness of 1.5 mm to 1.7 mm. For thicker wires, for example rectangular or flat wires with a thickness of more than 1.8 mm, the front end section A of the wire 2 can be pre-bent before being pushed into the guide device 50 or the shaping device 20. To this end, the device 1 has the Figures 1 , 2 , 5 , 6th and 7th Pre-bending device 70 shown for bending the end section A of the wire 2.

The pre-bending device 70 can be part of a plate 90 which is arranged on a holder 120 of the device 1 so as to be movable in the vertical direction. Figure 5 FIG. 13 shows a top side of the pre-bending device 70, while the bottom side of the pre-bending device 70 in FIG Figures 6 and 7th is shown. The pre-bending device 70 has a bending mandrel 71 around which the end section A of the wire 2 can be bent. The bending mandrel 71 can be designed as a cylindrical pin which protrudes from the underside of the plate 90.

For the actual bending of the end section A of the wire 2 around the bending mandrel 71, the pre-bending device 70 has a bending element 72 which is attached to a lever 73 as a pin or a cylindrical roller can be. The lever 73 can be rotatably mounted on a joint 76. The pre-bending device 70 furthermore has a recess 74 in the plate 90, in which the bending element 72 is movably arranged at a distance around the bending mandrel 71. The bending element 72 can be moved by means of the lever 73 along the path of a segment of a circle within the recess 74. For this purpose, the recess 74 is also arranged in the form of a segment of a circle in the plate 90. In the Figures 1 to 7 The illustrated embodiments of the device for winding a wire, in which two wires can be wound around different legs of the closed frame core 3 at the same time, the material recess 74 in the plate 90 has two circular segment-shaped partial recesses that merge into one another. For the sake of clarity, the Figures 5 , 6th and 7th The embodiments of the pre-bending device 70 shown here only show a wire 2 with an end section A which is bent by means of the pre-bending device 70.

To pre-bend the end section A of the wire 2, the wire is first clamped in the feed device 10 such that the front end section A of the wire protrudes from the feed device on the side of the feed device on which the guide device 50 is arranged. The plate 80 with the guide device 50, the shaping device 20 and the pitch transmitter device 30 fixed on the plate is arranged displaceably on the holder 120. In order to prebend the end section of the wire 2, the plate 80 is displaced along the holder 120 to a position P3. The pre-bending device 70 is connected to the plate 80 via a coupling element 130. The coupling element 130 is arranged on the holder 120 such that it can be displaced in the vertical direction.

When the plate 80 is displaced to the position P3, the pre-bending device 70 is accordingly displaced downward to a position P2, at the height of which the wire 2 protrudes from the feed device 1. To accommodate the wire 2, the pre-bending device 70 has the guide 75. After the plate 90 has been moved with the pre-bending device 70 from a position P1 above the position P2 to the position P2, the section A 'of the wire 2 located behind the end section A lies in the guide 75 of the pre-bending device, while the front section A of the initially still unbent wire 2 protrudes from the guide 75, as shown in FIG Figure 6 is shown.

By moving the lever 73 with the bending element 72 in the direction of the arrow around the joint or a pivot point 76 at which the lever 73 can be rotatably mounted and which is arranged, for example, on the upper side of the plate 90 on the bending mandrel 71, the end section A of the wire Pre-bent in a semicircular shape around the bending mandrel 71. Figure 7 FIG. 11 shows the pre-bent end portion A of the wire 2 bent into a curved portion of the guide 75. To hold the wire securely in the curved portion of the guide 75 along the bending mandrel, a cover 78 is provided over the curved portion of the guide 75. The cover 78 is arranged on the underside of the plate 80 and can have a cross-section in the shape of a segment of a circle. For the sake of clarity, in Figure 7 only one cover 78 is shown.

In addition to the Figures 5 , 6th and 7th A further second wire, which is guided parallel to the first wire in the device 1, can be bent by means of the pre-bending device 70. The pre-bending device a further lever 73 which moves a further bending element in a further recess 74.

For further bending or winding of the wire 2, the plate 90 is moved with the pre-bending device 70 from the position P2 back to the position P1. The plate 80 is moved from position P3, which is below position P2, back to position P2, as a result of which the front end section A of the now pre-bent wire 2 is inserted into the guide device 50 or the shaping device 20. The further bending or winding of the wire around the leg of the closed frame core 3 can now take place in a further automated manner by means of the device 1 as described above.
