Description

The present invention relates to a device for winding coils, in particular a device for winding coils of a relay.

For the winding of coil wire onto a coil former, the coil former is usually rotated along its longitudinal axis and the coil wire to be wound onto the coil former is delivered to the coil former in a direction perpendicular to the axis of rotation of the coil former. By moving the coil wire guide along the longitudinal axis, a spiral winding can be achieved on the coil body. However, such a method is useless if it is necessary to wind two separate windings separately around two bobbins arranged parallel to one another, which are arranged, for example, on a U-shaped coil yoke. In order to wind two separate windings on two bobbins arranged in this way, it is therefore necessary first to wind the two bobbins individually and only to arrange the bobbins already provided with windings on the yoke legs of the bobbin yoke. However, such a method is not efficient.

It is therefore the object of the present invention to provide a more efficient winding device for winding coil wire on the coil body of a relay and an improved method for winding coil wire on the coil body of a relay.

This object is solved by the subject matter of the independent claims. Advantageous embodiments of the invention are the subject of the dependent claims, the description and the accompanying figures.

According to a first aspect, the disclosure relates to a winding device for winding coil wire onto a first coil body and a second coil body of a coil yoke of a relay, the coil yoke having a first yoke leg with a first coil body and a second yoke leg with a second coil body, the first coil body extends in the direction of a first longitudinal axis, the second coil former extending in the direction of a second longitudinal axis, and the first coil former and the second coil former being arranged next to one another and aligned parallel to one another, with a rotatable winding holder for holding the coil yoke, with the winding holder around an axis of rotation is rotatable, the axis of rotation being aligned parallel to the first longitudinal axis and the second longitudinal axis, and wherein the winding receptacle is designed to slidably support the coil yoke transversely to the axis of rotation in order to f r the winding of coil wire onto the first coil former to position the first coil former such that the first longitudinal axis coincides with the axis of rotation, and to position the second coil former for winding coil wire onto the second coil former such that the second longitudinal axis coincides with the axis of rotation coincides, and a winding nozzle, which is designed to deliver the coil wire parallel to the axis of rotation.

This realizes the technical advantage of a winding device with the smallest possible space and an increased winding speed, which makes it possible to produce two separate bobbins arranged side by side.

With the positioning of one of the first and second bobbins on the axis of rotation, so that its longitudinal axis coincides with the axis of rotation, it is achieved that with a rotation of the winding holder around the axis of rotation, this specific bobbin is rotated about its longitudinal axis. The respective other bobbin rotates around the axis of rotation and around the longitudinal axis of the bobbin positioned on the axis of rotation.

The parallel alignment of the winding nozzle to the axis of rotation and to the longitudinal axis of the bobbin positioned on the axis of rotation and with the positioning of the winding nozzle directly next to the bobbin positioned on the axis of rotation means that the winding wire of the winding nozzle is wound exclusively on the bobbin by the rotation of the winding holder whose longitudinal axis coincides with the axis of rotation.

By moving the coil yoke within the winding receptacle transversely to the axis of rotation, the previously uncoiled bobbin can be positioned so that its longitudinal axis coincides with the axis of rotation. With the rotation of the winding receptacle about the axis of rotation and about the longitudinal axis of the bobbin, which is now positioned on the axis of rotation, it is possible to wind around this bobbin exclusively. Thus, two separate windings of the first and second coil formers are possible in succession in a winding process, without the coil yoke being removed from the winding device.

The rotation of the winding holder and thus the rotation of the bobbin to be wound relative to a winding nozzle arranged parallel to the axis of rotation can avoid one winding around the individual bobbins to use the respective bobbin rotatable winding nozzle. As a result, the installation space of the winding device can be reduced, since there is no need for complex, rotatable and pivotable mounting of the winding nozzle and for a corresponding drive for the winding nozzle.

In addition, the rotatable mounting of the winding receptacle can be designed in a technically simpler manner, since the winding receptacle exclusively performs its own rotation around the axis of rotation running through the winding receptacle, in contrast to a rotation of the winding nozzle around an axis of rotation arranged outside the winding nozzle. As a result, higher rotation speeds and consequently shorter winding times, as well as a higher winding precision and, in connection with this, a higher quality of the windings produced are possible.

According to one embodiment, the winding receptacle is designed to wind the coil wire of the winding nozzle onto the coil former whose longitudinal axis coincides with the axis of rotation by rotating about the axis of rotation. This has the technical advantage that the winding nozzle can be held stationary in order to wrap the coil body with coil wire. This is advantageous because it allows the winding device to be designed with a smaller installation space. Furthermore, the winding nozzle, which is held stationary during the winding process, enables a more precise and less error-prone winding than a winding nozzle rotating around the bobbin.

According to one embodiment, the winding receptacle is designed to rotate in a first direction of rotation around the axis of rotation in order to produce a first winding of the first coil former with a first winding direction, and to rotate in a second direction of rotation around the axis of rotation to produce a second winding of the second coil former with a second winding direction, which is opposite to the first winding direction. This achieves the advantage that the winding device can be used to achieve two windings with opposite winding directions in a winding process on a coil yoke with two coil cores.

According to one embodiment, the winding nozzle can be moved back and forth parallel to the axis of rotation and along the coil former, the longitudinal axis of which coincides with the axis of rotation, in order to achieve a uniform winding around the coil former with coil wire. This achieves the technical advantage of a spiral winding that extends over the entire length of the coil body. Furthermore, the translatory movement of the non-rotating winding nozzle achieves a solution that is technically as simple as possible to achieve a spiral winding. Due to the repeated repeated back and forth movement of the winding nozzle, a spiral winding with several layers of coil wire can also be achieved.

According to one embodiment, the winding receptacle comprises an upper receptacle part and a lower receptacle part, and the coil yoke is held between the upper receptacle part and the lower receptacle part. This has the technical advantage that the coil yoke is securely held in the winding holder,

According to one embodiment, the upper receiving part and the lower receiving part are detachably connected to one another via connecting means. This has the technical advantage that the coil yoke is securely held in the winding receptacle via a clamping connection between the upper and lower receiving parts. Furthermore, it is achieved that the coil yoke can be detached from the posture by the upper and lower receiving parts again by loosening the connection of the upper and lower receiving parts.

According to one embodiment, the upper receiving part and / or the lower receiving part have passages arranged next to one another, which can be penetrated by the first yoke leg and the second yoke leg, the first coil former and the second coil former being arranged outside the passages. This achieves the technical advantage that the coil yoke is securely held between the upper and lower receiving parts. Furthermore, through the passage of the passages through the yoke legs, the spool yoke is prevented from slipping transversely to the axis of rotation. Furthermore, by arranging the bobbins outside the passages, the bobbins can be completely wrapped with coil wire.

According to one embodiment, the passages arranged next to one another define a first positioning of the coil yoke and a second positioning of the coil yoke in the winding receptacle, the first longitudinal axis of the first coil former coinciding with the axis of rotation in the first positioning and the second longitudinal axis of the second in the second positioning Coil body coincides with the axis of rotation. This has the technical advantage that the positioning of the first and second bobbins in such a way that the first and second longitudinal axes coincide with the axis of rotation is facilitated. This ensures that the coil yoke is held in the winding receptacle in such a way that one of the first and second coil formers is wound exactly at all times for winding with coil wire is aligned with the axis of rotation of the winding holder.

According to one embodiment, the winding holder has a plurality of openings which penetrate the winding holder perpendicular to the axis of rotation and are provided to expose electrical connections, in particular connecting pins, of the coil yoke for the electrical connection of coil wire. This has the technical advantage that the coil yoke does not have to be removed from the winding receptacle in order to wrap the connecting pins of the coil yoke with coil wire through the winding nozzle and can instead be carried out during the winding process.

According to one embodiment, the winding receptacle has a plurality of support pins which are designed to fix the coil wire to the winding receptacle during the winding process. The support pins make it easy to fix the coil wire to the winding holder. As a result, the coil wire is held on the winding holder during the winding process and after completion, and the tension of the coil wire of the winding nozzle is maintained.

According to one embodiment, the elongated winding nozzle can be pivoted perpendicularly from the position parallel to the axis of rotation in order to enable the connection pins of the coil yoke to be wrapped. This achieves the technical advantage that no additional device is required to wrap the connecting pins of the coil yoke, but that this can be done through the winding nozzle. Furthermore, the swivel-mounted winding nozzle realizes a winding device with the smallest possible installation space.

According to one embodiment, the winding nozzle can be pivoted transversely to the axis of rotation in the vertical position in order to achieve different connecting pins of the coil yoke and / or different support pins of the winding holder for winding with coil wire. This in turn achieves the technical advantage that no additional device is required to wrap around the connecting pins, but rather that all connecting pins of the coil yoke and supporting pins of the winding holder can be reached by pivoting the winding nozzle perpendicular to the axis of rotation. Furthermore, the swivel-mounted winding nozzle realizes a winding device with the smallest possible installation space.

According to one embodiment, the winding nozzle is in the vertical position along a first direction, which is oriented parallel to the axis of rotation, along a second direction, which is oriented perpendicular to the first direction, and along a third direction, which is perpendicular to the first direction and the second direction is oriented, translationally movable. This ensures that all connecting pins of the coil yoke and all supporting pins of the winding holder can be reached through the winding nozzle.

According to one embodiment, the winding nozzle can be rotated in the vertical position about a second axis of rotation oriented at right angles to the axis of rotation of the winding receptacle in order to achieve the winding of the connecting pins of the coil yoke and / or the support pins of the winding receptacle with coil wire. This in turn achieves the technical advantage that no additional device is required for wrapping the connection pins and the support pins, but rather, due to the rotational movement of the winding nozzle perpendicular to the axis of rotation, the winding nozzle can wrap all the connection pins and support pins of the winding holder. Furthermore, a winding device with the smallest possible installation space is realized by the rotatably mounted winding nozzle.

According to one embodiment, the winding nozzle is designed to cut coil wire between a wound connection pin of the coil yoke and a wound support pin in order to end the winding process. This achieves the technical advantage that, at the end of the winding process, the coil wire is automatically separated between the connection pins of the coil yoke and the corresponding support pins, so that the coil wire with the finished first and second windings is manually separated and thus released manually Coil wire of the winding nozzle is avoidable. Furthermore, the coil wire remains on at least one support pin of the winding holder, so that a tension of the winding wire of the winding nozzle can be maintained.

In one embodiment, the first and second bobbins are formed in a sleeve shape from dielectric material. This achieves the technical advantage of a coil winding that is as technically efficient as possible.

According to a second aspect, the disclosure relates to a method for winding coil wire onto a first coil body and a second coil body of a coil yoke of a relay, the coil yoke having a first yoke leg with a first coil body and a second yoke leg with a second coil body, the first coil body extends in the direction of a first longitudinal axis, the second coil former extending in the direction of a second longitudinal axis, the first coil former and the second coil former being arranged next to one another and are aligned parallel to one another, with the method steps, arranging the coil yoke in a rotatable winding receptacle which is rotatable about an axis of rotation, the axis of rotation being aligned parallel to the first longitudinal axis and that of the second longitudinal axis, displacing the coil yoke in the winding receptacle transversely to the rotation axis and positioning one of the first and second bobbins so that its longitudinal axis coincides with the axis of rotation, delivering coil wire parallel to the longitudinal axis of a bobbin to the bobbin, the longitudinal axis of which coincides with the axis of rotation, through a winding nozzle, rotating the winding receptacle about the axis of rotation around the coil wire the winding nozzle on the bobbin, the longitudinal axis of which coincides with the axis of rotation.

It is thereby achieved that during a winding process, two bobbins arranged in parallel and next to one another are successively and separately wrapped with coil wire, and thus two windings can be achieved, a first winding being arranged on the first bobbin and a second winding being arranged on the second bobbin.

The method can be carried out by the device according to the first aspect. Further features of the method result directly from the embodiments and / or the functionality of the device.
