[0001] The present invention relates to a ring arrangement apparatus and a ring arrangement method for forming a coil winding of a component of an electric motor by means of a single ring or a plurality of concentrically arranged rings of an electrical conductor. Background Technology

[0009] This invention relates to the field of manufacturing components for motors, such as engines and generators, particularly mass production, and more particularly to the field of manufacturing coil windings for such components, such as stators. In particular, this invention relates to the field of hairpin technology, see [1]. According to this technology, such coil windings are formed from individual conductors, such as I-pins or hairpins, which are inserted into slots in the housing of the component, wherein the ends of the conductors are modified and subsequently connected to form coil windings. In order to insert the conductors, it is known from documents [2] to [6] that the conductors are first arranged into loops, and then the loops are inserted into the housing.

[0010] Therefore, for the manufacture of a stator for an electric motor, it is feasible to manufacture the required coil windings by providing multiple bent electrical conductors. These individual bent electrical conductors (hereinafter referred to as hairpins) are first arranged in a ring by the electrical conductors before they can be introduced into the laminations arranged for this purpose in order to manufacture the stator. Such a ring arrangement device is described in reference [6], which constitutes the closest prior art, and describes a ring arrangement device and a ring arrangement method in which conductors are embedded into a convergent receiving member with slots so as to form a ring therein. A slider is provided for each slot. When forming the ring, the conductor can be placed on the slider. If the slider is pulled out of the convergent receiving slot, the ring can be moved to a deeper position, where the ring can then be fixed and held by means of the slider clamping.

[0011] More precisely, [6] describes a ring arrangement device for forming a ring arrangement for a preferred U-shaped hairpin. Here, the hairpin is introduced into a converging receiver having radially arranged slots. A slider in the slot has several functions: thus, the slider supports the introduced hairpin in a higher position, i.e., the so-called insertion position, with its upper side. If a ring is inserted, the ring is placed in a lower support position. Here, the slider supports the inserted ring with its radially outward side. Subsequently, a ring to be inserted, radially inward, can then be placed on the upper side of the slider until the ring is complete.

[0012] The slider described in [6] can be designed not only to act from the inside out, but also to act from the outside in. [6] also describes a mechanical coupling between the actuating element and the radial slider of the pre-attached socket. Through this mechanical coupling, the movement of the actuating element is converted into radial movement of all sliders by means of a transmission. Therefore, all sliders can be actuated by means of an actuator. To achieve this coupling, the use of a tapered flange engaged in an inclined groove of the slider is exemplarily described in [6]. The use of a cam disc is also considered feasible in [6]. Summary of the Invention

[0013] Based on [6], the object of the present invention is to demonstrate the feasibility of further improvements in process technology for arranging conductors into loops to form coil windings.

[0014] To achieve the aforementioned objectives, the present invention provides a ring arrangement device and a ring arrangement method according to the present invention.

[0015] Advantageous design solutions are the topics described below.

[0016] According to one aspect of the present invention, a ring arrangement device is provided for forming a coil winding of a component of an electric motor by forming a ring arrangement of a single ring or multiple concentrically arranged rings of an electrical conductor, said ring arrangement device having:

[0017] A convergent receiving member having a plurality of receiving spaces arranged annularly around an axis, open in the axial direction and limited by a limiting portion extending in the radial direction, the receiving spaces being used to receive conductor segments into which the conductors should be axially embedded when forming a ring.

[0018] At least one radially inner slider in each receiving space, wherein the radially inner slider has a (first) clamping surface pointing in a radial direction within the receiving space.

[0019] At least one radially outer slider in each receiving space, wherein the radially outer slider has a (second) clamping surface pointing in another radial direction within the receiving space.

[0020] The inner radial slider can move radially, and the outer radial slider can move radially.

[0021] Specifically, it is proposed that the radially inner slider has a radially outward-pointing end face as an inner clamping surface in the receiving space, and the radially outer slider has a radially inward-pointing end face as an outer clamping surface in the receiving space. In particular, the first (slider) clamping surface formed at the radially inner slider is an inner clamping surface in the corresponding receiving space, while the second (slider) clamping surface formed at the radially outer slider is an outer clamping surface in the corresponding receiving space. Clamping can then be achieved by moving the sliders toward each other or, in other words, by pressing the sliders together.

[0022] In particular, the corresponding slider with an internal clamping surface having a corresponding receiving space is referred to here as a radially internal slider, regardless of whether the slider is operable from the inside or from the outside and whether it extends radially inward or radially outward by means of a connecting end or connector or as a whole component. The corresponding slider with an external clamping surface having a corresponding receiving space is referred to as a radially external slider, regardless of whether the slider is operable from the inside or from the outside and whether it extends radially inward or radially outward by means of a connecting end or connector or as a whole component.

[0023] In some embodiments, a corresponding radially inner slider with an inner clamping surface is operable radially inward, and a corresponding radially outer slider with an outer clamping surface is operable radially outward. In some embodiments, a corresponding radially inner slider with an inner clamping surface is operable radially outward, and a corresponding radially outer slider with an outer clamping surface is operable radially inward. In some embodiments, a corresponding radially inner slider with an inner clamping surface is operable radially inward, and a corresponding radially outer slider with an outer clamping surface is operable radially inward. In a preferred embodiment, a corresponding radially inner slider with an inner clamping surface is operable radially outward, and a corresponding radially outer slider with an outer clamping surface is operable radially outward.

[0024] The converging receiver can be constructed in different ways. In some embodiments, a single component, such as a radially defined portion having a receiving space, is presented as the converging receiver. In other embodiments, the converging receiver is not a single component; it can, and if necessary, be formed only by one group of sliders, such as radially inner sliders.

[0025] In some embodiments, the radially inner slider and the radially outer slider are driven together. In some particularly preferred embodiments, the radially outer slider can move radially independently of the radially inner slider.

[0026] In some embodiments, the radially inner slider and / or the radially outer slider each have a flat support surface area on their upper side, on which at least one conductor may be supported for positioning during loop formation.

[0027] In some implementations, it is proposed that one slider overlaps another slider in each slider assigned to a receiving space.

[0028] In some implementations, the radially inner sliders respectively surround the radially outer sliders.

[0029] In some embodiments, it is proposed that the radially extending boundary portion of the receiving space is formed at least partially at one of the sliders belonging to the receiving space.

[0030] In some embodiments, at least one, more, or all of the radially inner slider and / or radially outer slider are configured as multiple pieces. Particularly, a first slider portion has an end face acting as a clamping surface, and a second slider portion has a connecting end for connection to a slider assembly motion device for causing the slider assembly to move together. In some embodiments, the first and second slider portions are connected to each other via an accumulator or elastic element. Preferably, the first slider portion can move radially relative to the second slider portion against the resistance of the accumulator or elastic element.

[0031] In some implementations, the first slider portion surrounds the second slider portion.

[0032] In some embodiments, a connection end for connection to an individualized motion device is provided at the first slider portion, by means of which the first slider portion can move radially relative to the second slider portion against the resistance of an accumulator or elastic element.

[0033] Some embodiments of the ring arrangement device have a first slider group motion device for causing the radially inner sliders to move radially together. Some embodiments of the ring arrangement device have a second slider group motion device for causing the radially outer sliders to move radially together. Some embodiments have both a first slider group motion device and a second slider group motion device. In a particularly preferred embodiment, the second slider group motion device can be operated independently of the first slider group motion device.

[0034] In some embodiments, the first slider assembly motion device is proposed to have a first cam disk that can be rotated by means of a first actuator, and the rotational motion of the first cam disk can be converted into the radial motion of the radially inner slider by means of a cam-carrying-coupling device.

[0035] In some embodiments, the second slider assembly motion device is proposed to have a second cam disk that can be rotated by means of a second actuator, and the rotational motion of the second cam disk can be converted into the radial motion of the radially outer slider by means of a cam-carrying-coupling device.

[0036] In some embodiments, the slider assembly motion device is proposed to have cam disks that are concentric with each other.

[0037] In some embodiments, the first slider group motion device and the second slider group motion device are driven by an actuator disposed radially outside.

[0038] Some embodiments of the ring arrangement device have an individualized motion device connected to a first slider portion of one of the sliders, the individualized motion device being configured to move the first slider portion individually and independently of the slider group motion device, the second slider portion of the slider being coupled to the slider group motion device together with the other sliders of the same slider group.

[0039] In some embodiments, the converging accommodator is proposed to have a pre-insertion ring disposed axially offset from the slider, wherein at least one sub-region of the accommodating space is bounded by a fixed radial boundary wall region.

[0040] In some embodiments, at least one sub-region of the receiving space in the pre-fitting ring is defined by a boundary wall region extending radially and circumferentially. In other embodiments, the circumferential boundary is omitted.

[0041] In some embodiments, the pre-insertion ring is proposed to be axially movable relative to the radially inner slider and the radially outer slider.

[0042] For example, the pre-inserted ring can move axially relative to the converging receiver to place the pre-inserted ring in a supported position.

[0043] In some embodiments, it is proposed that the radially inner slider and the radially outer slider be guided at a slider guide that is axially movable relative to the pre-insertion ring.

[0044] According to another aspect, the present invention provides a ring arrangement method for forming a coil winding of a component of an electric motor by forming a ring arrangement from a single ring or multiple concentrically arranged rings of an electrical conductor, the ring arrangement method comprising:

[0045] a) Provide a ring arrangement device according to any one of the above embodiments,

[0046] b) Provides a radially inner slider and / or a radially outer slider in a pre-insertion posture, wherein the radially inner slider and / or the radially outer slider are at least partially moved into the receiving space;

[0047] c) Inserting the conductor segment of the electrical conductor into the receiving space, such that the conductor segment is supported on a slider that has at least partially moved into the receiving space in the pre-insertion posture, and forming a loop with the electrical conductor.

[0048] d) Moving the ring from the pre-insertion position to the support position or setting it in an intermediate position between the pre-insertion position and the support position, in the pre-insertion position, the conductor forming the ring protrudes from the convergence receiver, and in the support position, the conductor forming the previous ring is supported for inserting another ring.

[0049] e) Move the radially inner and outer sliders relative to each other so that the conductor in the pre-insertion position or intermediate position is clamped between the clamping surfaces formed at the sliders.

[0050] Here, step e can be performed by moving the sliders relative to each other in a direction toward each other ("pressing together") or in a direction away from each other ("pulling apart"), depending on the orientation of the clamping surfaces at the respective sliders.

[0051] Some embodiments of the ring arrangement equipment have a control device configured to cause the ring arrangement equipment to perform the previously mentioned ring arrangement method.

[0052] Embodiments of the present invention relate to card issuing technology, and more particularly to a ring arrangement device having retaining sliders that are mechanically decoupled from each other.

[0053] The advantages of some preferred embodiments of the present invention are described in detail below.

[0054] Unlike existing technologies, in some embodiments, at least some of the receiving spaces are provided with radially inner sliders and radially outer sliders for each receiving space. If at least one radially inner slider and one radially outer slider are provided for each receiving space, improved clamping between the sliders is possible. Clamping can be performed at different radial positions. In particular, the hairpin ring can be clamped not only at the radially inner groove wall portion or only at the radially outer groove wall portion as in [6], but also at an intermediate position between two opposing sliders. Support surfaces for supporting additional conductors can also be selectively provided radially inner and radially outer of the already inserted ring for inserting adjacent rings. Thus, for example, rings with different radii can be inserted, and inner and outer rings can be inserted in any order. Depending on the operation of the sliders, individual conductors can also be clamped at intermediate positions. Therefore, the device and method can be used more extensively.

[0055] In some embodiments, at least one slider is constructed in a multi-piece configuration, wherein the first slider portion and the second slider portion are movable relative to each other. This allows, for example, the slider to be manipulated by means of different actuating elements. Preferably, the slider portions are coupled to each other, for example, elastically coupled to each other. For example, a two-piece slider is provided, wherein the two portions are kinematically decoupled by springs. It is also feasible to provide a multi-piece slider in embodiments where each receiving space has only one slider, rather than only in embodiments where two opposing sliders are provided in each receiving space.

[0056] In some embodiments, each receiving slot contains two opposing sliders, with a particularly specific construction and arrangement of two-piece sliders, each spring-decoupled from its two parts. In some embodiments, the radially inner slider is not also actuated radially inward—which is more difficult to achieve in terms of structural space—but rather actuated radially outward from the radially outer slider. Therefore, in some embodiments, it is proposed that the radially inner slider surrounds the radially outer slider; in other words, the radially inner slider encloses the radially outer slider.

[0057] The advantages of an implementation having one or more multi-piece sliders (possibly in combination with reverse sliders) are described in detail below in comparison with the prior art according to [6].

[0058] In [6], the retaining sliders are coupled to each other through a common operation. The coupled retaining sliders can only clamp all the hairpins in the ring arrangement if there are the same number of hairpin legs in each slot of the ring arrangement. If there are more hairpins in one slot than in others, only the hairpin legs in that slot can be clamped due to the mechanical coupling of the sliders. If the position of some hairpins is not precisely defined by the retaining sliders, the hairpins may deviate from their desired positions, which may interfere with the process flow. Therefore, ring arrangement devices to date are designed for operation in slots with uniform filling. In slots with non-uniform filling, in addition to process uncertainty, the described mechanical coupling of a single slider also presents the risk that, in the worst case, the entire motor force is applied to a single slider. Therefore, the device must be constructed very robustly, otherwise this situation may cause damage to the sliders or cam rollers.

[0059] Furthermore, in [6], due to mechanical coupling, all slot sliders must be forcibly opened in order to introduce a single hairpin. Here, all slot hairpins are also in an undefined state, and in the worst case, the hairpins may leave this undefined state, potentially disrupting the process flow.

[0060] Furthermore, in existing technologies, hairpins with legs of varying lengths are positioned with only one leg resting on the retaining slider in the insertion position. The other leg does not contact the slider. Therefore, uncontrolled tilting of the hairpin is possible.

[0061] Furthermore, it is not feasible to clamp a single hairpin in a position between the insertion position and the support position. There are hairpins for which clamping in such an intermediate position is advantageous. Examples of this include hairpins with a flat wire leg—the so-called I-shaped flat wire.

[0062] To achieve a persistently clamped state after each hairpin is assembled in the ring arrangement device, some embodiments propose that the retaining sliders of the respective receiving spaces (e.g., slots) of the assembly receiver can be opened or closed independently of each other. In some embodiments, the clamping state of the hairpin in the receiving space (e.g., slot) is achieved independently of the number of flat wire legs filling the corresponding receiving space. It is also feasible to collectively change the position of all retaining sliders of the device relative to the hairpin so that the retaining sliders can be selectively converted to a clamped or unclamped state. This state should be set for the assembly process step itself and subsequent process steps, such as removing the hairpins from the device.

[0063] To meet the foregoing requirements, in a particularly preferred embodiment, there is no longer a rigid mechanical coupling between the individual slider portions acting on the flat wire and the central adjustment device. More precisely, the ring arrangement device is configured such that the individual slider portions for gripping the flat wire are decoupled from the movement of the operating element or transmission device by means of a slider system, particularly spring-supported sliders.

[0064] Therefore, the retaining force of the slider portion abutting the hairpin is applied by means of a transmission device via the compression of a spring. The spring travel can compensate for different fillings of the receiving space (e.g., slot) of the converging receiving element.

[0065] Similarly, the corresponding holding force at the flat wire can be changed according to the posture of the transmission device and the resulting change in the spring compression.

[0066] In a preferred design, the radial movement of all the sliders can also be achieved via a central drive. Within the spring travel range, each individual slider portion associated with the flat wire can also be opened and closed via one and / or more additional external actuating elements, such as pneumatic cylinders. These additional actuating elements can be either rigidly connected to the assembly housing or movable relative to it.

[0067] In embodiments of the present invention, the (multi-piece) slider can clamp the flat wire not only from the radial inside to the radial outside in the pre-insertion socket (hereinafter referred to as the radial inner slider), but also from the outside to the inside (hereinafter referred to as the radial outer slider). Combinations are also possible.

[0068] Unlike existing technologies, in a preferred embodiment of the present invention, the individual slider portions gripping the conductor are mechanically decoupled from their central control transmission via an accumulator, such as a spring. This allows for the targeted opening and closing of individual sliders via an externally located actuating element, in addition to simultaneously opening and closing all sliders. Therefore, hairpins can be introduced into a single slot while the remaining slots remain closed and the hairpins therein remain in a tensioned position. Furthermore, even if the slots of the converging device are equipped with different numbers of hairpins, the hairpins in all slots can be clamped simultaneously via a cam disc combined with the spring travel of the sliders.

[0069] Equally feasible is to securely hold the U-shaped hairpin with legs of different lengths in the seat using a nestmechanik, in which the longer leg is already clamped by a slider in the insertion position, while the shorter leg stands on a closed slider in another slot. Alternatively, in this type of hairpin, both legs can be clamped.

[0070] Furthermore—especially due to the reverse slider in the receiving space—it is feasible to clamp the hairpin in a position between the insertion position and the support position. This provides the advantage that it is possible to transfer the flat wire to a second unit during the insertion process, which then turns the hairpin to its final support position to eliminate gravity-controlled movement. This prevents undesirable movement of the hairpin.

[0071] Furthermore, it is meaningful to introduce the complete flat wire loop into the converging seat in the intermediate position so as to permanently hold the hairpin loop in the clamped position. This forms an extension of the previous insertion position, in which the flat wire was only placed on the slider. The clamped position of the entire loop prevents the hairpin from tilting in a non-defined direction.

[0072] Some embodiments of the present invention can achieve kinematic decoupling of all individual sliders from the motion mechanism designed to make all sliders move in the same way. This means that the primary motion makes all sliders move in the same way, but each individual slider can still be controlled by secondary motions. Therefore, a single functional position can be turned on / off, while all other functional positions (Valenz) are turned off / on.

[0073] Some embodiments of the invention incorporate accumulators, such as springs, which enable different numbers of flat wires to be held / clamped at each height between the support position and the insertion position.

[0074] Some embodiments of the present invention can achieve straight positioning of U-shaped flat lines with different leg lengths by clamping one leg while positioning the other leg above the slider / on the end side of the slider.

[0075] Some embodiments of the present invention can achieve positioning / clamping of the I-shaped flat wire at each height between the support position and the insertion position. Attached Figure Description

[0151] The accompanying drawings show different views of an embodiment of the ring arrangement device 10, which is used to form a ring arrangement 12 by a ring 14 or a plurality of concentrically arranged rings 14.1, 14.2 of an electrical conductor 16 in order to form the coil windings of a component of an electric motor.

[0152] Conductor 16 is a conductor with a particularly U-shaped or generally hairpin-shaped bend having two legs 16.1, 16.2 and a top region 16.3, referred to below as hairpin 18, or a special conductor in the form of an I-shaped flat wire 20 for connecting coils.

[0153] For example, especially from Figures 1 to 8 as well as Figures 63 to 70 As can be seen, a converging receiving member 22 is provided, which has multiple receiving spaces 24 for accommodating conductor segments—particularly the legs 16.1, 16.2 of the hairpin 18 or the I-shaped flat wire 20. The receiving spaces 24 are arranged annularly around an axis, open in the axial direction, and limited by a limiting portion extending in the radial direction. When forming the rings 14, 14.1, 14.2, the conductor segments 16.1, 16.2 are axially embedded into the receiving spaces 24. Due to its shape, the receiving space 24 will also be referred to below as a groove.

[0154] Each receiving space 24 is provided with at least one slider 28, 30, which is movable between at least two positions in the slider movement direction to clamp or release at least one conductor segment 16.1, 16.2 embedded in the receiving space 24 by means of clamping surfaces 32, 34. Details of preferred embodiments of sliders 28, 30 are provided in Figures 9 to 32 As shown in the image.

[0155] according to Figures 1 to 14 as well as Figures 20 to 32 Each receiving space 24 is provided with at least one radially inner slider 28, wherein the radially inner slider 28 has a radially outward pointing end face as an inner clamping surface 32 in the receiving space 24 and can move radially.

[0156] according to Figures 1 to 8 as well as Figures 15 to 32 Each receiving space 24 is provided with at least one radially external slider 30, each of which has a radially inwardly pointing end face as an external clamping surface 34 in the receiving space 24 and can move radially.

[0157] according to Figures 9 to 32 At least one, more, or all of the sliders 28 and 30 are configured in a multi-piece manner, such that clamping surfaces 32 and 34 are formed at the first slider portions 28.1 and 30.1, and connecting ends 36 and 38 for connection with slider assembly motion devices 40 and 42 are formed at the second slider portions 28.2 and 30.2, which are used to enable the slider assembly to move together. The first slider portions 28.1 and 30.1 and the second slider portions 28.2 and 30.2 can move relative to each other in the slider movement direction.

[0158] In particular, at least one, a plurality, or especially preferably all of the radially movable inner sliders 28 are multi-piece sliders, with a radially outward-pointing end face at their first slider portion 28.1 serving as an inner clamping surface 32, which in some embodiments not shown acts against the radially outer boundary of the receiving space, or according to the illustrated embodiment acts against the radially outer slider 30 belonging to the same receiving space 24.

[0159] Furthermore, in particular, at least one, a plurality, or especially preferably all of the radially movable outer sliders 30 are multi-piece sliders, with a radially inwardly pointing end face at their first slider portion 30.2 forming an outer clamping surface 34, which in an embodiment not shown acts against the radially inner boundary of the receiving space 24, or in the illustrated embodiment against the radially inner slider 28 belonging to the same receiving space 24.

[0160] The radially inner slider 28 and / or the radially outer slider 30 each have flat support surface areas 44 and 46 on their upper sides, on which at least one conductor 16 can be supported for positioning during the formation of rings 14, 14.1, and 14.2. In the illustrated multi-piece sliders 28 and 30, the flat support surface areas 44 and 46 are respectively provided on the first slider portions 30.1 and 30.2.

[0161] The first slider portions 28.1 and 30.1 and the second slider portions 28.2 and 30.2 are connected to each other by a accumulator or an elastic element—for example, in the form of a spring 50, such as a helical compression spring. The first slider portions 28.1 and 30.1 can move relative to the second slider portions 28.2 and 30.2 in the slider movement direction against the resistance of the accumulator or elastic element 50.

[0162] The first slider portions 28.1 and 30.1 are provided with connecting ends 52 and 54 for connecting with the individualized motion devices 56 and 58. With the aid of the individualized motion devices, the first slider portions 28.1 and 30.1 can move relative to the second slider portions 28.2 and 30.2 in the slider movement direction.

[0163] according to Figures 9 to 32 The radially inner slider 28 and the radially outer slider 30 are configured such that one slider of each slider 28 and 30 belonging to a receiving space 24 overlaps with the other slider. In particular, the radially inner slider 28 surrounds the radially outer slider 30.

[0164] Furthermore, the radially extending boundary portion 26 of the receiving space 24 is formed at least partially at one of the sliders 28 belonging to the receiving space 24.

[0165] In the illustrated embodiment, the first slider portion 28.1 of the radially inner slider 28 is provided with a longitudinal opening 60 or groove extending in the radial direction, the limiting wall of the longitudinal opening or groove forming the limiting portion 26 of the receiving space 24, and the radially outer slider 30 is radially movable and received in the longitudinal opening or groove.

[0166] according to Figures 1 to 26 , Figures 29 to 32 as well as Figures 63 to 70 The system includes slider group motion devices 40 and 42, configured to cause a slider group having multiple sliders 28 and 30 to move together. In particular, it includes a first slider group motion device 40 for causing the radially inner sliders 28 to move radially together, and a second slider group motion device 42 for causing the radially outer sliders 30 to move radially together, which can be operated independently of the first slider group motion device 40.

[0167] The slider group motion devices 40 and 42 can be configured in completely different ways. In particular, the slider group motion device has a central transmission device 61 for the convergent slider movement of all sliders 28 and 30 of the connected slider group, i.e., for example, all radially inner sliders 28 or all radially outer sliders 30.

[0168] In some variations not shown, the radially inner slider 28 and the radially outer slider 30 can be jointly operated by a common central drive. For example, a single cam disk is provided, which is coupled to all sliders 28, 30 and configured such that the radially inner slider 28 and the radially outer slider 30 move in opposite directions relative to each other.

[0169] In the illustrated variant, the first slider assembly motion device has a first cam disk 62, which can be rotated by means of a first actuator 64. The rotational motion of the first cam disk 62 is converted into the radial motion of the radially inner slider 28 by means of a cam-carryer-coupler device 70.

[0170] In the illustrated embodiment, the first connecting end 36 at the second slider portion 28.2 of the radially inner slider 28 is connected to the cam-carryer-coupled device 70, or used as a carrier of the cam-carryer-coupled device 70.

[0171] In the illustrated variant, the second slider assembly motion device 42 has a second cam disk 66, which can be rotated by means of a second actuator 68. The rotational motion of the second cam disk 66 is converted into the radial motion of the radially outer slider 30 by means of a cam-carryer-coupler device 72.

[0172] In the illustrated embodiment, the second connecting end 38 at the second slider portion 30.2 of the radially outer slider 30 is connected to the second cam-carryer-coupled device 72, or used as a carrier of the cam-carryer-coupled device 72.

[0173] The cam discs 62 and 66 of the slider group motion device 40 and 42 are concentric with respect to each other.

[0174] according to Figures 62 to 66 The first slider group motion device and the second slider group motion device 40, 42 are driven by actuators located radially outside.

[0175] The main assembly of the ring arrangement device 10, referred to herein as the converging accommodator 22 or pre-plug 74, having sliders 28, 30, slider guide 76 and pre-plug ring 78, can be rotated by means of a third actuator 80 so as to rotate the corresponding accommodating space 24 toward the plugging point, where the plugging of the conductor 16 provided by means of a clamp or the like (not shown) is performed.

[0176] according to Figures 1 to 12 , Figures 15 to 18 , Figures 21 to 24 , Figures 29 to 32 as well as Figures 64 to 70 The system includes at least one individual motion device 56, 58, which can be connected to a first slider portion 28.1, 30.1 of one of the sliders 28, 30. The individual motion devices 56, 58 are configured to move the first slider portion 28.1, 30.1 individually and independently of the associated slider group motion devices 40, 42.

[0177] The number, composition, and arrangement of individualized motion devices 56 and 58 can vary greatly depending on the implementation scheme and requirements of the component to be manufactured.

[0178] In some embodiments not shown, each multi-piece slider is equipped with its own individualized motion device 56, 58.

[0179] In particular, at least one first integrated manipulation device 56 may be connected to a first slider portion 28.1 of one of the radially inner sliders 28 so that the first slider portion 28.1 moves independently of the first slider group motion device 40 coupled to the second slider portion 28.2.

[0180] In particular, at least one second integrated manipulation device 58 may be connected to a second slider portion 30.1 of one of the radially outer sliders 30, so that the first slider portion 30.1 moves independently of the second slider group motion device 42 coupled to the second slider portion 30.2.

[0181] In the illustrated embodiment, a plurality of first integrated manipulation devices 56 are spaced apart in the circumferential direction to individually manipulate a plurality of radially inner sliders. Furthermore, a second integrated manipulation device 58 is provided, by which radially outer sliders 30 can be individually manipulated.

[0182] In the illustrated embodiment, individualized manipulation devices 56 and 58 are disposed radially outside the pre-plug seat 74. For example, the individualized manipulation devices are disposed at the stationary holding device 82, wherein the sliders 28 and 30 to be manipulated can be rotated toward the individualized manipulation devices by rotating the pre-plug seat 74.

[0183] Individualized control devices 56, 58 have radially external or externally located control elements 86, 88, such as magnetically operable, electrically operable, hydraulically operable or pneumatically operable cylinders.

[0184] according to Figures 1 to 4 , Figures 21 to 24 as well as Figures 29 to 37 The converging receiver 22 has a pre-insertion ring 78 axially offset from the sliders 28 and 30, in which at least one sub-region of the receiving space 24 is bounded by a fixed radial boundary wall region 84. Optionally, the pre-insertion ring 78 may also have a boundary wall region 84 that is radially and circumferentially bounded. The pre-insertion ring 78 is axially movable relative to the sliders 28 and 30. Furthermore, the converging receiver 22 has a slider guide 76, for example, with a slotted disc, for guiding the slider movement.

[0185] In the embodiment of the ring arrangement device 10 shown in the accompanying drawings, the motion of each slider 28, 30 is decoupled from that of the transmission device 61 by means of a spring-supported slider system.

[0186] Therefore, the retaining force of the sliders 28 and 30 abutting the hairpin is applied by means of the transmission device 61 via the compression of the spring 50. The spring travel can compensate for the uneven filling of the slots or receiving spaces 24 of the converging receiving member 22.

[0187] Similarly, depending on the position of the transmission device 61 and the resulting change in the compression of the spring 50, the corresponding holding force at the conductor 16 (hereinafter also referred to as the flat wire) can be changed.

[0188] The convergent radial movement of all sliders 28, 30 is possible via a central drive 61. Within the range of the spring travel, each individual multi-piece slider 28, 30 can also be opened and closed via one and / or more additional external actuating elements 86, such as pneumatic cylinders—examples of individual actuating devices 56, 58.

[0189] The additional actuating elements 86, 88 may either be rigidly connected to the assembly receiving member 22, or (as in...) Figures 63 to 66 (as shown in the diagram) moves relative to the assembly containment.

[0190] In some embodiments, sliders 28 and 30 can clamp onto the flat wire from the radial inside to the radial outside in the pre-insertion socket 74 (hereinafter referred to as radially inner slider 28), and in some embodiments, they can clamp from the outside to the inside (hereinafter referred to as radially outer slider 30). Combinations (clamping from the inside and from the outside) are also possible, as illustrated in the accompanying drawings.

[0191] exist Figures 1 to 3 The diagram shows the overall structure of the slider system, including the externally located operating elements 86 and 88. Here, the shown hairpin ring is clamped from the inside and from the outside via sliders 28 and 30.

[0192] It can also be seen that the externally located actuating elements 86 and 88 can individually open and close sliders 28 and 30 within the range of spring travel. The pneumatic cylinder shown above in the figures—an example of the actuating element 86 of the second integrated actuating device 58—can actuate the (radially outer) slider 30 by pulling, while the cylinder below—an example of the actuating element 88 of the first integrated actuating device 56—can actuate the (radially inner) slider 28 by pressing. Specifically, Figure 1 The overall view of the pre-insertion connector 74 is shown in 2D as a sectional view; Figure 2 The overall view of the pre-insertion connector 74 is shown in sectional view in orthographic projection. Figure 3 The overall view of the pre-insertion socket 74 is shown in orthographic projection.

[0193] exist Figure 4 The mechanical device of the pre-insertion socket 74 and the external operating elements 86 and 88 can be seen more precisely in the middle. Figure 4 The orthographic projection shows a slider 24 with an open receiving space—the radially inner slider 28 and the radially outer slider 30 are opened via cam disks 62 and 66. Figure 5 The situation is illustrated in 2D as a cross-section.

[0194] Figure 6 The cam disks 62 and 66 of the slider assembly motion devices 40 and 42 are shown. In particular, Figure 6 This is a top-view perspective of the ring arrangement device 10, showing the cam disks 62 and 66. All radially outer sliders 30 can be centrally operated via the internal cam disk 66. The radially inner slider 28 is controlled by the external cam disk 62. Figure 7The ring arrangement device 10 is shown from below, with cam discs 62 and 66 exposed. Figure 8 The ring arrangement device 10 is shown from above in a 2D diagram, in which the attachment of the control elements 86, 88 can be seen more clearly.

[0195] In the illustrated embodiment, each slider 28, 30 is mechanically decoupled from its central control transmission 61 via spring 50. This allows for the targeted opening and closing of individual sliders 38, 30 via external actuating elements 86, 88, in addition to simultaneously opening and closing all sliders 28, 30. Thus, hairpins can be introduced into a single slot / receiving space 24, while the remaining slots / receiving spaces 24 remain closed and the hairpins therein remain in the tensioned position. Furthermore, even if the individual slots / receiving spaces 24 of the converging receptacle 22 are equipped with different numbers of hairpins, the hairpins in all slots / receiving spaces 24 can be clamped simultaneously via cam discs 62, 66 in conjunction with the spring travel of sliders 28, 30.

[0196] Equally feasible is to securely hold the U-shaped hairpin with legs 16.1 and 16.2 of different lengths in the pre-insertion seat 74 by means of a mechanical device, in such a way that the longer leg 16.1 is already clamped in the insertion position by the sliders 28 and 30, while the shorter leg 16.2 stands on the closed sliders 28 and 30 in another slot / another receiving space 24. Alternatively, in such a hairpin, both legs 16.1 and 16.2 can also be clamped.

[0197] Alternatively, the hair clip can be clamped in a position between the insertion position and the support position. This provides the advantage that the flat wire can be transferred to a second unit during the insertion process, which then moves the hair clip to its final support position to eliminate gravity-controlled movement. This prevents undesirable movement of the hair clip.

[0198] It may also be meaningful to introduce the complete flat wire loop into the converging seat in the intermediate position so as to permanently hold the hairpin loop in the clamped position. This forms an extension of the insertion position according to [6], in which the flat wire is only placed on the slider. The clamped position of the complete loop prevents the hairpin from tilting in a non-defined direction.

[0199] Therefore, some implementations can achieve kinematic decoupling of all individual sliders from the motion mechanism designed to make all sliders 28, 30 move in the same way. This means that the primary motion makes all sliders 28, 30 move in the same way, but each individual slider can still be controlled by secondary motions. Thus, individual functional positions can be opened / closed, while all other functional positions are closed / open.

[0200] Some implementations include springs that are advantageous for holding / clamping different numbers of flat wires at each height between the support position and the insertion position.

[0201] Some implementations can achieve straight positioning of U-shaped flat lines even if their leg lengths are different, by clamping one leg while positioning the other leg above the slider / on the end of the slider.

[0202] Some implementations can achieve positioning / clamping of the I-shaped flat wire at each height between the support position and the insertion position.

[0203] The following is based on Figures 9 to 14 The possible structure and function of the radial internal slider 28 are described in detail. Figures 9 to 11 The diagram shows a frontal three-view view of the components of the radial inner slider 28, the first slider group motion device 40, and the first integrated manipulation device 56. Figure 12 The component is shown in a 2D sectional view. Figure 13 and Figure 14 This is an exploded view, which shows the construction of the enclosed radially inner slider.

[0204] The radially inner sliders 28 have an inward clamping mechanism—an inner clamping surface 32—and are individually actuated via an externally located actuating element 86 that applies pressure. All radially inner sliders 28 move collectively via an external first cam disk 62.

[0205] Here, the radially inner slider 28 is constructed in two parts. The inner slider portion—the second slider portion 28.2—is connected to the first cam disk 62 via the cam roller 90—an example of the first connecting end 36 and the drive of the cam-drive-coupler device 70—and can be moved directly by the first cam disk.

[0206] The inner second slider portion 28.2 is connected to the outer, surrounding slider portion—the first slider portion 28.1—by means of a slightly pre-tensioned spring 50. If the first cam plate 62 is now adjusted, the inner second slider portion 28.2 moves directly together, and the outer first slider portion 28.1 follows the movement of the inner second slider portion 28.2 via the slightly pre-tensioned spring 50.

[0207] If the clamping end face of the first slider portion 28.1 surrounding the hairpin ring 14.1—the inner clamping face 32—presses against the hairpin ring 14.1, which has been introduced into the converging receiver 22, the spring 50 is further compressed. A retaining force is applied to the hairpin ring 14.1 in this manner.

[0208] To open the single slot / single receiving space 24, i.e., to create a gap between the inner clamping surface 32 on the end side of the enclosing first slider portion 28.1 and the existing hairpin ring 14.1, the following process is performed: The outer first actuating element 86 (pneumatic cylinder, etc.) is now pressed from the radial outside onto the first slider portion 28.1 enclosing the radially inner slider 28, which includes the inner clamping surface 32. The actuating element 86 (actuator) has a higher force than the force that the spring 50 can apply between the two slider portions 28.1, 28.2. As a result, the spring 50 is fully compressed, thereby causing the first slider portion 28.1 enclosing the radially inner slider 28 to move radially inward. Conversely, the second slider portion 28.2, which is directly connected to the first cam plate, does not change its radial position.

[0209] After the corresponding flat wire / conductor 16 is introduced into the separately opened receiving space, the first actuating element 86, which applies pressure, is now moved in again. As a result, the first slider portion 28.1, surrounded by the radially outer slider 28, presses against and clamps the newly introduced conductor 16 with its end-side clamping surface 32 via spring force. Compared to before, the spring 50 is now further compressed by the wire width.

[0210] The following is based on Figures 15 to 20 The diagram illustrates in detail the possible structure and function of the radial outer slider 30. Figures 15 to 17 The diagram shows an orthographic view of the components of the radial outer slider 30, the second slider group motion device 42, and the second individualized manipulation device 58. Figure 18 The components are shown in a sectional 2D view, and Figure 19 and Figure 20 An exploded view of a component having a radially outer slider 30 is shown.

[0211] The radially outer slider 30 has an inward clamping mechanism—an outer clamping surface 34—and is individually actuated via an externally located second actuating element 88. All radially outer sliders 30 move collectively via an internal second cam disk 66.

[0212] In the illustrated embodiment, the radially outer slider 30 is also constructed in two parts. The inner second slider portion 30.2 of the radially outer slider 30 is also connected to the second cam disk 66 via the cam roller 92—an example of the drive element of the second connecting end 38 and the cam-drive-coupler 72—and can be directly moved by the second cam disk. The inner second slider portion 30.2 is further connected to the outer surrounding first slider portion 30.1 by means of a slightly pre-tensioned spring 50. If the second cam disk 66 is now adjusted, the inner second slider portion 30.2 moves directly together, and the outer first slider portion 30.1 follows the movement of the inner second slider portion 30.2 via the slightly pre-tensioned spring 50.

[0213] If the clamping end face of the first slider portion 30.1 surrounding the hairpin ring 14.1—the outer clamping face 34—presses against the hairpin ring 14.1, which has been introduced into the converging receiver 22, the spring 50 is further compressed. A retaining force is applied to the hairpin ring 14.1 in this manner.

[0214] To open the single slot / single receiving space 24, i.e., to create a gap between the clamping surface 34 on the end side of the surrounding first slider portion 30.1 and the existing hairpin ring 14.1, the following process is performed: the external second actuator—the second operating element 88—(pneumatic cylinder, etc.)—now pulls the first slider portion 30.1 surrounding the radially inner slider 30 outward, the first slider portion including the clamping surface 34. The actuator has a higher force than the force that the spring 50 can apply between the two slider portions 30.1, 30.2. As a result, the spring 50 is fully compressed, thereby causing the first slider portion 30.2 surrounding the radially outer slider 30 to move radially outward. Conversely, the second slider portion 30.2 of the radially outer slider 30, which is directly connected to the second cam disk 66, does not change its radial position.

[0215] After the corresponding flat wire / conductor 16 is introduced into the separately opened slot, the pressing actuator—the second actuating element 88—is now removed again. As a result, the first slider portion 30.1, surrounded by the radially outer slider 30, presses against and clamps the newly introduced flat wire with its end-side clamping surface 34 via spring force. Compared to before, the spring 50 is now further compressed by the wire width.

[0216] The following is based on Figures 21 to 28 The combined function of the radially inner slider 28 and the radially outer slider 30 is explained. In the illustrated embodiment, each receiving space is provided with a radially inner slider 28 and a radially outer slider 30.

[0217] Figure 21The diagram shows a three-dimensional overall view of the two sliders 28 and 30, with the slot / accommodation space 24 opening in the center via cam discs 62 and 66. Figure 22 The same situation is illustrated in a sectional 2D view. Here, not only does the radially inner slider 28 open by its radially inward movement, but the radially outer slider 30 also opens by its radially outward movement. This creates a free space between the inner clamping surface 32 and the outer clamping surface 34, and between the radially limiting portion 26 formed by surrounding the radially inner slider. This free space aligns with the slots in the pre-insertion seat ring and the slots in the plate of the slider guide device 76.

[0218] Figure 23 The overall three-view diagram of the two sliders 28 and 30 is shown, wherein the slot / accommodation space 24 is closed via cam disks 62 and 66. Figure 24 The same situation is shown in a sectional 2D view. Here, not only is the radially inner slider 28 closed by its further radial outward movement, but the radially outer slider 30 is also closed by its further radial inward movement, causing the clamping surfaces 32 and 34 to move relative to each other. The corresponding radial positions of the inner clamping surface 32 and the outer clamping surface 34, which are in contact or in the closed state, can be adjusted by setting two opposing sliders 28 and 30. In this way, the radial position of the clamped conductor segment in the receiving space can also be adjusted.

[0219] Supporting surface areas 44 and 46 are located on the upper side of sliders 28 and 30. When conductor segments 16.1 and 16.2 of conductor 16 are inserted into the slots of pre-insertion seat ring 78 and slider guide device at insertion ring 14.1, the conductor segments can be supported on supporting surface areas 44 and 46, so that conductor 16 remains in the insertion position during insertion.

[0220] exist Figure 25 and Figure 26 The exploded view of the assembly consisting of radial inner sliders and radial outer sliders 28 and 30 is shown in triangular and 2D. Figure 27 and Figure 28 A cross-sectional view of the component is shown to illustrate the surrounding of the radially inner slider 28 with respect to the radially outer slider 30.

[0221] from Figures 25 to 28 And especially Figure 27 and Figure 28 It is clear that the radial outer slider 30 can move within and be guided by the radial inner slider 28.

[0222] Apart from the outer radial slider 30 being guided within the inner radial slider 28 in the Y-direction (see coordinate system - circumferential direction) and upward and downward (Z-direction - axial direction), there is no mechanical coupling between the inner radial slider 28 and the outer radial slider 30. The two sliders 28, 30 can move independently of each other in the radial direction (here: the X direction) via associated cam disks 62, 66 or associated external actuating elements 86, 88.

[0223] In the arrangement, the radially inner slider 28 provides a clamping end face—inner clamping surface 32—that can clamp the hair clip from the radial inside to the outside. The radially outer slider 30 provides a clamping end face—outer clamping surface 34—that can clamp the hair clip from the radial outside to the radial inside.

[0224] By means of enclosure, the slider 28, which is clamped radially inward, can be controlled via a cam disk 62 or an actuating element 86, which can be positioned radially outward. Thus, the cam disk 62 for the radially inward slider 28 can be positioned radially outward than the cam disk 66 responsible for the movement of the radially outward slider 30. Therefore, the operation of the cam disk 62 is significantly simplified, as it can be driven from the outside and does not require laborious under-traction.

[0225] Furthermore, the control elements 86 and 88 that require fluid supply can be located outside the assembly housing 22. This significantly simplifies the supply process. Because the entire pre-fitting socket 74 rotates during the pre-fitting process, this would necessitate rotating the guide section or energy chain.

[0226] Furthermore, by enclosing, space can be saved in the radially inner region of the assembly housing 22, since the transmission device 61 and the actuating elements 86, 88 (cam discs 62, 66, pneumatic cylinders, etc.) can be moved outward. Depending on the inner diameter of the stator, the arrangement of the sliders 28, 30 is feasible only by the described enclosing.

[0227] In addition, it is feasible to use a less refined, and therefore more affordable, slider component.

[0228] The following is based on Figures 29 to 32 The advantages and functions of the multi-piece sliders 28 and 30 and their individual operating devices 56 and 58 provided in the illustrated embodiment of the ring-arranged device 10 are explained in detail. In particular, the operation of the external operating elements 86 and 88—examples of the individual operating devices 56 and 58—is explained in detail.

[0229] exist Figures 29 to 32 In the scenario shown, the positions of the slider assembly motion devices 40 and 42 are different from those in... Figure 23 and Figure 24The same applies, meaning the slider assembly motion device is positioned to jointly close the radially inner slider 28 and the radially outer slider 30. Specifically, with... Figure 23 and Figure 24 In contrast, the positions of cam discs 62 and 66 remain unchanged.

[0230] Figure 29 A frontal three-view view of the ring arrangement device 10 is shown, in which a radially outer slider 30 is shown to open independently within the range of the spring travel by means of an associated externally located actuating element 88. Figure 30 The same situation is illustrated in a cross-section two-dimensional diagram.

[0231] The first slider portion 30.1 of the radial outer slider 30, which has an external clamping surface 34—that is, the section that contacts the flat wire—is opened by means of a separate actuating element 88 (the upper pneumatic cylinder). Therefore, only this one actuated radial outer slider 30 is opened at this time. All other radial outer sliders 30 remain closed.

[0232] Figure 31 A frontal three-view view of the ring arrangement device 10 is shown, in which a radially inner slider 28 is shown to open independently within the range of the spring travel by means of an associated externally located actuating element 86. Figure 32 The same situation is illustrated in a cross-section two-dimensional diagram.

[0233] The first slider portion 28.1 of the radial inner slider 28, which has an internal clamping surface 32—that is, the section that contacts the flat wire—is opened by means of a separate pressing actuating element 86 (the pneumatic cylinder below). Therefore, only this one actuated radial inner slider 28 is opened at this time. All other radial inner sliders 28 remain closed.

[0234] The following is based on Figures 33 to 62 This paper details the process steps of different implementation methods for the ring arrangement method.

[0235] The invention relates to a ring arrangement method for forming a ring arrangement 12 by a single ring 14 or a plurality of concentrically arranged rings 14.1, 14.2 of electrical conductors 16, 18, to form a coil winding of a component of an electric motor, the ring arrangement method comprising:

[0236] • A ring arrangement device 10 is provided according to one embodiment of the embodiments described above.

[0237] The ring arrangement method can be automated, especially with the help of ring arrangement equipment 10. For example, in... Figure 66As schematically shown, the ring arrangement device 10 has a control device 94, which is communicatively connected to actuators 64, 68, 80, 86, 88, and configured to cause the ring arrangement device 10 to perform the steps of the embodiment of the ring arrangement method described below. In particular, the control device 94 has a processor 96 and a memory 98, in which a computer program is stored, which causes the execution.

[0238] In a variation of the slider design that also applies to one-piece sliders, the ring arrangement method includes the following steps:

[0239] • Provides radially inner and / or radially outer sliders 28, 30 in a pre-insertion posture 100, in which the radially inner and / or radially outer sliders are at least partially moved into the receiving space 24;

[0240] • Conductor segments 16.1 and 16.2 of the electrical conductor 16 are inserted into the receiving space 24, such that conductor segments 16.1 and 16.2 are supported on sliders 28 and 34 that have at least partially moved into the receiving space 24 in the pre-insertion posture 100, and a ring 14.1 is formed by the electrical conductor 16.

[0241] • The ring 14.1 is moved from the pre-insertion position 102 to the support position 104 or disposed in an intermediate position 106 between the pre-insertion position 102 and the support position 104, in which the conductor 16 forming the ring 14.1 protrudes from the convergence receiving member 22, and in the support position, the conductor 16 forming the previous ring 14.1 is supported for inserting another ring 14.2;

[0242] • Move the radial inner slider and the radial outer slider 28, 30 toward each other so that the conductor 16 in the pre-insertion position 102 or intermediate position 106 is clamped between the clamping surfaces 32, 34 formed at the sliders 28, 30.

[0243] In a variation of an embodiment that also applies to having only one slider per slot, wherein at least one of the sliders is configured in a multi-piece manner, the ring arrangement method includes the following steps:

[0244] • Slider 28, 30 are provided in a pre-insertion posture 100, in which the slider is at least partially moved into the receiving space 24;

[0245] • Conductor segments 16.1 and 16.2 of the electrical conductor 16 are inserted into the receiving space 24, such that conductor segments 16.1 and 16.2 are supported on sliders 28 and 30 that have at least partially moved into the receiving space 24 in the pre-insertion posture 100, and rings 14 and 14.1 are formed by the electrical conductor 16.

[0246] • The rings 14, 14.1 are moved from the pre-insertion position 102 to the support position 104 or disposed in an intermediate position 106 between the pre-insertion position 102 and the support position 104, in which the conductor 16 forming the rings 14, 14.1 protrudes from the convergence receiving member 22, and in the support position, the conductor 16 forming the previous ring 14.1 is supported to insert the additional ring 14.2;

[0247] • By moving sliders 28 and 30 to the clamping position, conductor 16 will be clamped in the pre-interlocking position 102 or the intermediate position 106; and

[0248] • Move the first slider portions 28.1 and 30.1 of the multi-piece sliders 28 and 30 so that the conductor 16 in the associated receiving space 24 moves, while the conductors 16 in the other receiving spaces 24 remain clamped.

[0249] Alternatively, in contrast to the previous ring arrangement method, it is also feasible to form only a single ring 14 and then remove the ring by first closing all the sliders, and then, when the individualized control devices 56 and 58 are no longer operated, the flat wire is introduced by the individual operation of the first slider portions 28.1 and 30.1 and then in a clamped state.

[0250] The following is based on Figures 33 to 37 The diagram illustrates a feasible process flow for pre-inserting the hairpin ring 14.2, wherein a regular hairpin with a U-shaped form and the same leg length is inserted as a conductor 16. Individualized operating devices 56, 58, such as external operating elements 86, 88, are not used here initially.

[0251] Figure 33 A frontal three-section view of the ring arrangement device 10 is shown, in which the previously inserted ring 14.1 has been positioned in the support position 104 and clamped there by sliders 28 and 30. In particular, Figure 33 The first hairpin ring 14.1 is shown clamped via cam discs 62 and 66; at least one spring 50 for applying clamping force is slightly compressed; external actuating elements 86 and 88 are not engaged.

[0252] Figure 34 This shows a front three-view diagram of the ring arrangement device 10, wherein from Figure 33Starting from the beginning, another regular hairpin ring 14.2 is placed radially further inward on the slider 28. The conductor 16 (regular hairpin) of the second ring 14.2 to be inserted stands on the inner support surface region 44 with its conductor segments 16.1, 16.2 inserted into the receiving space 24, thereby being held in the pre-insertion position 102, the inner support surface region being formed above the first slider portion 28.1 of the radially inner slider 28.

[0253] Figure 35 This illustrates how, in the next process step, sliders 28 and 30 are opened via slider assembly movement devices 56 and 58, such as cam disks 62 and 66. In the method shown here, sliders 28 and 30 are not opened along the entire movement path; they are opened only enough to release the clamping action. The previously inserted first ring 14.1 is removed from the support position 104 by means of the upper portion of the converging receiver 22—for example, a pre-insertion seat ring 78 that is axially movable relative to sliders 28 and 30. Furthermore, the newly inserted second ring 14.2 is lifted away from sliders 28 and 30 from the pre-insertion position 102 by the relative movement of the upper portion.

[0254] Figure 36 The next process step is shown, in which sliders 28 and 30 are further opened, for example, fully opened, via slider assembly movement devices 40 and 42—e.g., cam disks 62 and 66. In particular, Figure 36 The lowering of the two rings 14.1 and 14.2 is shown with the sliders 28 and 30 fully opened via the cam discs 62 and 66. The individual operating devices 56 and 58, especially the external operating elements 86 and 88, are not engaged.

[0255] Figure 37 The next process step after the insertion of the second ring 14.1 is shown. Slider 28, 30 are fed via slider group movement devices 40, 42, such that the sliders clamp the ring arrangement 12 formed by the first ring and the second rings 14.1, 14.2 from the radial inside and radial outside.

[0256] In the specific implementation plan Figure 37 The ring arrangement device 10 is shown in orthographic projection, with rings 14.1 and 14.2 clamped in support position 104. Rings 14.1 and 14.2, formed by hairpins 18 acting as conductors 16, are clamped via cam discs 62 and 66. A spring 50 for applying clamping force is slightly compressed in two sliders 28 and 30. External actuating elements 86 and 88 are not engaged.

[0257] As in Figure 37As can be seen, rings 14.1 and 14.2 can be maintained at a radial distance from the possible circumferential boundary of the slot / accommodation space 24 of the converging receiver 22. Therefore, it is feasible to insert the third ring radially further in, in the same manner as previously described for the second ring, or it is feasible to insert it radially further out, wherein the hairpin 18 of the third ring is then supported in the pre-insertion position 102 on the support surface region 46 formed on the outer side of the radially outer slider 30.

[0258] Therefore, by setting the reverse sliders 28 and 30, different variations of the insertion scheme of rings 14, 14.1, and 14.2 with different radii can be achieved.

[0259] like Figure 38 and Figure 39 As shown, it is also possible to clamp the rings 14, 14.1, 14.2 at any height between the insertion position 102 and the support position 104—intermediate position 106. Figure 38 A 2D cross-sectional view of the ring arrangement device is shown, in which the first ring 14.1 is clamped in the support position 104, and the second ring 14.2 is clamped in the intermediate position 106. Therefore, clamping of ring 14.2 is also feasible at half height. Here, the springs 50 in the respective sliders 28, 30 for applying the clamping force are slightly compressed. The external actuating elements 86, 88 are not engaged. Figure 39 The same situation is shown as a triangulation diagram.

[0260] The following describes in detail some advantages of decoupling sliders 28 and 30 from their corresponding slider motion devices 40 and 42—especially by means of the configuration of a multi-piece slider with an accumulator or elastic element, such as a spring 50.

[0261] As described above, through decoupling, it is possible that the accommodating space 24 can also be filled in different ways.

[0262] One advantage is that a single conductor 16 can be introduced into the receiving space 24 while conductors in other receiving spaces remain clamped, as is more precisely illustrated below with reference to an embodiment.

[0263] As follows Figures 40 to 46 As explained, even when ring 14.2 is in an intermediate position, it is feasible to insert a single flat wire 20 into the converging receiver 22 while the already inserted flat wire 18 remains in the clamped position. This will be illustrated below with an example: an I-shaped flat wire 20 should be inserted at the location of the coil winding subsequently formed by the ring arrangement.

[0264] Here Figure 38 and Figure 39The scenario shown is the starting point, in which the first ring 14.1 is clamped in the support position 104 and the second ring 14.2 is clamped in the intermediate position 106.

[0265] For this purpose, a single slider 28 is first operated by means of an externally located actuating element 86. Because both the radially inner slider 28 and the radially outer slider 30 are configured in multiple parts in the embodiment shown here, another flat wire 20 can be inserted not only radially inner but also radially outer. The insertion radially inner is described below, for which the radially inner slider 28 is operated individually. Therefore, the receiving space 24, which should accommodate the I-shaped flat wire, opens radially inward via the individualized actuating device 86.

[0266] Figure 40 A 2D view is shown, illustrating a radially inner slider 28 that opens separately within the range of the spring travel by means of an externally located actuating element 86—e.g., a pressing cylinder below. An I-shaped flat line 20 extends from above.

[0267] Figure 41 A 2D view showing the subsequent process steps is provided, showing the radially inner slider 28 that opens separately within the range of the spring travel by means of the externally located actuating element 86 (the cylinder below that is pressed); the I-shaped flat wire 20 is inserted into the corresponding half-height—mid position 106.

[0268] The newly introduced flat wire 20 is placed at a preset depth and can now be clamped individually in the new position. For this purpose, the externally located actuating element 86 is moved in. Therefore, the resiliently mounted slider 28 is again clamped internally at the flat wire 20, as this... Figure 42 As shown in the image. Figure 42 In the 2D diagram, the manipulator 86 is no longer engaged. The radially inner slider 28 is pressed against the newly introduced I-shaped flat line 20 by spring force.

[0269] The process of inserting a single I-shaped flat line 20 into the middle position, just described in the 2D diagram, is again presented in the orthographic view. Figures 43 to 45 As shown in the image. Figure 43 The radially inner slider 28, which opens independently within the range of the spring travel by means of an externally located actuating element 86 (the lower cylinder that is pressed), is shown with an I-shaped flat line 20 coming from above. Figure 44 The radially inner slider 28, which opens independently within the range of the spring travel by means of an externally located actuating element 86 (the lower pressing cylinder), is shown, with the I-shaped flat wire 20 inserted into the corresponding half-height—intermediate height 106. Figure 45 In the middle, the operating element 88 is no longer engaged, and the radially inner slider 28 is pressed against the newly introduced I-shaped flat wire 20 by spring force.

[0270] As in Figure 46 As shown in the figure, it is also possible to clamp a single flat wire 20 at half height—intermediate position 106—when the remaining rings 14.1, 14.2 are in another position, such as support position 104. Figure 46 A 2D view is shown, in which an I-shaped flat line 20 is shown clamped at half height via a radially inner slider 28.

[0271] Therefore, it is feasible to introduce a single flat wire 20, while the flat wires 18 of all other slots / accommodating spaces 24 remain clamped. The following is based on... Figures 47 to 50 Taking the introduction of an I-shaped flat line 20 in the radial interior as an example and according to Figures 51 to 58 A feasible method for this purpose is illustrated by introducing an I-shaped flat wire radially outward. The ring arrangement consisting of hairpin rings 14.1 and 14.2 is shown here in support position 104.

[0272] Figure 47 A 2D diagram showing the initial configuration is provided, with the two rings 14.1 and 14.2 in the support position 104. The radially inner slider 28 and the radially outer slider tension the two rings 14.1 and 14.2. The spring 50, used to apply the clamping force, is slightly compressed; the external actuating elements 86 and 88 are not engaged.

[0273] Figure 48 The radially inner slider 28, which opens independently within the range of the spring travel by means of the externally located actuating element 86 (the lower cylinder that is pressed), is shown in a triangular view; the I-shaped flat line 20 comes from above.

[0274] Figure 49 The radially inner slider 28, opened independently within the spring travel range by means of the externally located actuating element 86 (the lower pressing cylinder), is shown in a three-dimensional view; the I-shaped flat line 20 is introduced from above. The same situation is again shown in a two-dimensional view. Figure 51 As shown in the image.

[0275] Figure 50 The I-shaped flat wire 20 is shown in its final position in a triangular view, with the pressing actuating element 86 having moved back; the I-shaped flat wire 20 is clamped by the spring force of the radially inner slider 28. The same situation is shown again in a 2D diagram. Figure 52 As shown in the image.

[0276] Because in the example described, both the radially outer slider 30 and the inner slider 28 are mechanically decoupled from the cam disks 62 and 66, the illustrated arrangement is also feasible for the radially outer I-shaped flat wire 20, as in... Figures 53 to 58 As shown in the diagram.

[0277] Figure 53The radially outer slider 30, which opens independently within the range of the spring travel by means of the externally located actuating element 88 (the upper, pulling cylinder), is shown in a 2D view. The I-shaped flat line 20 comes from above. Figure 54 A 2D view shows a radially outer slider 30 that opens independently within the spring travel range by means of an externally located actuating element 88 (the upper, pulling cylinder), with the I-shaped flat wire 20 guided downwards. The same situation applies in… Figure 56 The diagram is shown in three-view form. (As shown in...) Figure 57 As shown in the orthographic view, the I-shaped flat wire is in its final position, while the radially outer slider 30 opens independently within the spring travel range by means of the externally located actuating element 88; the slot / accommodating space 24 thus continues to open radially outward via the externally located pulling cylinder, allowing the I-shaped flat wire to be inserted into its final position. Figure 55 2D graphics and in Figure 58 As shown in the orthographic view, the I-shaped flat wire 20 is then in its final position, and the external actuating element 88 is no longer engaged; therefore, the I-shaped flat wire 20 is clamped by the radially external slider 30.

[0278] As follows Figures 59 to 62 As illustrated in the diagram, it is also feasible to clamp the hairpin 18 with legs 16.1 and 16.2 of different lengths.

[0279] Figure 59 A 2D view of the ring arrangement device 10 is shown, in which a clamping hairpin 18 with legs 16.1, 16.2 of different lengths is shown. The longer leg 16.1 of the hairpin 18 is clamped within the spring travel of the radially inner slider 28. This is shown in combination with the first hairpin ring 14.1 already in the supported position. The same situation is shown in... Figure 61 The image is shown in a three-view diagram. The clamped hairpin 18 is individually positioned within the ring arrangement device 10. Figure 60 It is shown in 2D and in Figure 62 The diagram is shown in the orthographic projection.

[0280] Therefore, compared to the receiving groove 24 which is flush with the shorter leg 16.2 in the axial direction (the shorter leg, but not extending downward to the clamping portion), there are more conductor segments in the receiving groove 24 that accommodates the longer leg 16.1. Different filling degrees of the receiving groove 24 can be handled by means of decoupling of the multi-piece sliders 28, 30.

[0281] Figures 63 to 70 Another view shows the pre-plugged connector 74 and the individualized control devices 56, 58.

[0282] Figure 63A perspective view of the overall pre-insertion connector 74 is shown, in which the hairpin 18 is in the support position 104 and does not have externally located operating elements 86, 88, and feasible implementations of the first to third actuators 64, 68, 80 are also shown.

[0283] Figure 64 A perspective view of the entire ring arrangement device 10 is shown, including the pre-insertion socket 74 and the externally located operating elements 86, 88, and the hairpin 18 in the support position 104.

[0284] Figure 65 An exemplary perspective view is shown of the externally located operating elements 86, 88 (eight operating elements 86 on the left side facing the radially inward direction of action, and a pulling operating element 88 on the right side facing the radially outward direction of action).

[0285] Figure 66 A perspective view of the entire ring arrangement device 10 is shown, including the externally located operating elements 86, 88 and the hairpin 18 in the insertion position 102. The control device 94 is also schematically shown here. The control device 94 may be a single control device for controlling only the ring arrangement device 10, or it may be part of a facility control device for a facility for manufacturing components (e.g., a hairpin-stator manufacturing facility).

[0286] Figure 67 A top view of the entire ring arrangement device 10 is shown, showing the externally located operating elements 86, 88 and hairpin 18.

[0287] Figure 68 A top view of the entire ring arrangement device 10 is shown, illustrating the externally located operating elements 86 and 88, while the hairpin is not shown. A slightly enlarged view is available. Figure 69 I saw it in the middle.

[0288] Figure 70 The image shows a bottom view of the ring arrangement device 10, with cam discs 62, 66 and externally located actuating elements exposed.

[0289] exist Figures 1 to 70 In this embodiment, the opposing sliders 28 and 30, respectively provided for each receiving space 24, are operated radially outward. Accordingly, the opposing sliders 28 and 30 extend radially outward via connecting ends or connecting portions. To distinguish between the sliders 28 and 30, the slider with the inner clamping surface 32 is referred to as the radially inner slider 28, regardless of how it extends as a component or via connecting ends or connecting portions, while the slider with the outer clamping surface 34 is referred to as the radially outer slider 30.

[0290] In all that has been explained so far, and in Figures 1 to 70In the embodiment shown, the corresponding radially inner slider 28 with an inner clamping surface 32 can be operated radially outward, and the corresponding radially outer slider 30 with an outer clamping surface 34 can also be operated radially outward. In other embodiments, the sliders 28 and 30 can also be operated in other ways.

[0291] In some embodiments not shown, the corresponding radially inner slider 28 with an inner clamping surface 32 can be operated radially inward—for example, in a manner known from [6]—and the corresponding radially outer slider with an outer clamping surface can be operated radially outward, for example, as this is achieved in the previously described embodiments. In some other embodiments not shown, the corresponding radially inner slider 28 with an inner clamping surface 32 can be operated radially inward, and the corresponding radially outer slider 30 with an outer clamping surface 34 can also be operated radially inward. In one embodiment, schematically in Figures 71 to 74 In some embodiments shown, the corresponding radially inner slider 28 with an inner clamping surface 32 can be operated radially outward, and the corresponding radially outer slider 30 with an outer clamping surface 34 can be operated radially inward.

[0292] Generally, the opposing sliders 28 and 30 move toward each other with their clamping surfaces 32 and 34 to close, and move away from each other with their clamping surfaces 32 and 34 to open.

[0293] Figures 71 to 74 The schematic diagram above shows reversed sliders 28 and 30 for one of the receiving spaces 24, wherein the conductor 16 to be received in the receiving space 24 is in a different orientation. Slider 28 and 30 are shown as a single unit here, but one or both sliders of slider 28 and 30 may also be as shown in other versions. Figures 1 to 70 It is composed of multiple parts as described.

[0294] The radially outer slider 30, having an outer clamping surface 34, extends radially inward via a limiting portion 26 on one side of the receiving space 24 and a connecting member 108 to a second slider group motion device 42 (not shown here), which is located radially inside. The radially inner slider 28, having an inner clamping surface 32, extends radially outward via a limiting portion 26 on the other side of the receiving space 24 and a connecting member 110 to a first slider group motion device 40 (also not shown here), which is located radially further outward.

[0295] exist Figure 71In this embodiment, sliders 28 and 30 are closed. Therefore, in this embodiment, slider 30, which extends radially inwards overall via the limiting portion 26 and connector 108 and has an external clamping surface 34, moves radially inwards; and in this embodiment, slider 28, which extends radially outwards overall via the limiting portion 26 and connector 110 and has an internal clamping surface 32, moves radially outwards. The converging seat or converging accommodator 22 (not shown here) is configured such that the accommodating space 24 of the slot is closed and has a bottom. Conductor 16 is in the plugged position, in which hairpin 18 protrudes mostly from the ring arrangement device 10 (as also described in reference [6]). Conductor 16 rests on the support surface areas 44 and 46 on the upper side of sliders 28 and 30.

[0296] Figure 72 Shown with Figure 71 In the same embodiment, sliders 28 and 30 are fully open. For this purpose, in this embodiment, slider 30, which is radially actuated from the radial inside and extends radially inward and has an external clamping surface 34 (i.e., radially external, i.e., slider 30 acting from the radial outside), moves radially outward; and in this embodiment, slider 28, which is radially actuated from the radial outside and extends radially outward and has an internal clamping surface 32 (i.e., radially internal, i.e., slider 28 acting from the radial inside), moves radially inward. The converging seat or converging accommodator 22 (not shown here) is configured such that the accommodating space 24 of the slot is open and has no bottom. The conductor 16 is in a supported position in which the hairpin 18 is mostly accommodated in the ring arrangement device 10 (as also described in reference [6]). The conductor 16 is not clamped by sliders 28 and 30, and therefore is not positioned or held.

[0297] Figure 73 Showing the clamped position and in Figure 71 and Figure 72 The same implementation scheme is used. For this purpose, sliders 28 and 30 move to the flat wire contact portion. Specifically, in this embodiment, slider 30, which is radially manipulated from the radial inward and extends radially inward, and has an external clamping surface 34 (i.e., the radially external slider 30, i.e., the slider 30 acting from the radial outward), moves radially inward to contact the conductor group; and in this embodiment, slider 28, which is radially manipulated from the radial outward and extends radially outward, and has an internal clamping surface 32 (i.e., the radially internal slider 28, i.e., the slider 28 acting from the radial inward), moves radially outward to contact the conductor group. The conductor 16 is in a supported position. The conductor 16 is clamped by the clamping surfaces 32 and 34 of sliders 28 and 30, thereby being positioned and held.

[0298] If possible Figure 74As exemplarily known, arbitrary intermediate states also exist. Slider 28, 30 can move independently of each other, allowing the sliders to occupy intermediate positions. A portion of the conductor group—for example, the two conductors 16 shown on the right—stands on the support surface region 44 or 46 on the upper side of slider 28, 30 and is in a plugged position. In the exemplary intermediate position shown, a portion of the conductor group is clamped / positioned / held by the clamping surfaces 32, 34 of slider 28, 30—which can also act as positioning surfaces and are referred to as positioning surfaces—see the four conductors 16 shown on the right.

[0299] A ring arrangement device (10) for forming an electrical conductor (16, 18) to form a coil winding is described. The ring arrangement device is provided with a converging accommodator (22) having a plurality of accommodating spaces (24) arranged around an axis for accommodating conductor segments (16.1, 16.2) of the conductor (16, 18) that should be axially embedded therein when forming the ring (14, 14.1, 14.2).

[0300] In an alternative for improving the process technology, it is proposed that each of the receiving spaces (24) has at least one radially inner slider (28) having a first clamping surface (32), and that each of the receiving spaces (24) has at least one radially outer slider (30) having a second clamping surface (34), wherein the radially inner slider and the radially outer slider (28, 30) can move radially in particular in opposite directions.

[0301] Alternatively, for process improvement, an alternative is proposed in which each receiving space (24) is provided with only at least one slider (28, 30) to clamp the conductor (16) therein. At least one, a plurality of or all of the sliders (28, 34) are configured in multiple pieces such that a clamping surface (32, 34) is formed at the first slider portion (28.1, 30.1) and a connecting end (52, 54) for connection with a slider group motion device (40, 42) is formed at the second slider portion (28.2, 30.2) for connecting the slider group motion device for moving the slider group together, wherein the slider portions (28.1, 30.1; 28.2, 30.2) can move relative to each other in the slider movement direction.
