Description

Technical Field

[0001] This utility model relates to the technical field of axial flux motor production equipment, and in particular to a winding ejection device for axial flux motor coil windings. Background Technology

[0002] The stator assembly of an axial flux motor includes coil windings and a stator core. The coil windings and stator core are manufactured separately and then assembled together. Specifically, the coil windings need to be wound first on a fixture containing multiple winding jigs, each capable of winding one coil. The wound coil windings are then ejected from the fixture, and finally, the ejected coil windings are assembled with the stator core. To improve the compactness of the axial flux motor structure, the spacing between two adjacent stator teeth within the stator core is small. Since the coil windings removed from the fixture need to be directly embedded into the stator core, the structure of the fixture must be identical to that of the stator core, meaning the spacing between two adjacent winding jigs within the fixture is small. This results in the winding nozzle used to feed the wire being unable to extend into the gap between two adjacent winding jigs, preventing the winding nozzle from accurately positioning the wire to the intended location, affecting the winding effect of the coil windings and failing to meet actual winding requirements.

[0003] A new method for winding coils by hooking the wire from the inside and outside of the winding trolley has been developed. Specifically, hooking devices are installed on the inside and outside of the winding trolley, respectively. These hooking devices move relative to the winding trolley in space and hook the wire from the inside and outside of the winding trolley, thus completing the winding of the coil without the winding nozzle passing through the gap between two adjacent winding trolleys.

[0004] However, due to the presence of the hook-and-loop device, the overall size of the fixture is relatively large. If the existing ejection device is added on top of this, it will not only significantly increase the required installation space and production costs, but also easily cause interference between the ejection device and the hook-and-loop device, affecting normal operation.

[0005] Therefore, there is an urgent need to invent a winding ejection device for axial flux motor coil windings to solve the above problems. Utility Model Content

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0062] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0063] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0065] The stator assembly of an axial flux motor includes coil windings and a stator core. The coil windings and stator core are manufactured separately and then assembled together. Specifically, the coil windings need to be wound first on a fixture containing multiple winding jigs, each capable of winding one coil. The wound coil windings are then ejected from the fixture, and finally, the ejected coil windings are assembled with the stator core. To improve the compactness of the axial flux motor structure, the spacing between two adjacent stator teeth within the stator core is small. Since the coil windings removed from the fixture need to be directly embedded into the stator core, the structure of the fixture must be identical to that of the stator core, meaning the spacing between two adjacent winding jigs within the fixture is small. This results in the winding nozzle used to feed the wire being unable to extend into the gap between two adjacent winding jigs, preventing the winding nozzle from accurately positioning the wire to the intended location, affecting the winding effect of the coil windings and failing to meet actual winding requirements.

[0066] A new method for winding coils by hooking the wire from the inside and outside of the winding trolley has been developed. Specifically, hooking devices are installed on the inside and outside of the winding trolley, respectively. These hooking devices move relative to the winding trolley in space and hook the wire from the inside and outside of the winding trolley, thus completing the winding of the coil without the winding nozzle passing through the gap between two adjacent winding trolleys.

[0067] However, due to the presence of the hook-and-loop device, the overall size of the fixture is relatively large. If the existing ejection device is added on top of this, it will not only significantly increase the required installation space and production costs, but also easily cause interference between the ejection device and the hook-and-loop device, affecting normal operation.

[0068] To solve the above problems, such as Figure 1 As shown, this embodiment provides a winding and ejection device for an axial flux motor coil winding. The winding device for the axial flux motor coil winding includes a winding fixture 100, a drive module, a hook module, and an ejection mechanism 600. The winding fixture 100 has multiple winding bobbins 1111 arranged sequentially along a preset path. Each winding bobbin 1111 extends axially and provides support for the axial winding of the wire 2000. The drive module is configured to drive the wire 2000 to move arbitrarily within space relative to the winding fixture 100. The hook module has a first hook member 210 and a second hook member. Both the hooking member 210 and the second hooking member can move arbitrarily in space and hook the wire 2000 from the inside and outside of the winding fixture 100, respectively. The ejection mechanism 600 is provided at one end of the winding jig 1111 along the axial direction. The ejection mechanism 600 has a first state fixedly connected to the hooking module and a second state separated from the hooking module. The hooking module can drive the ejection mechanism 600 in the first state to move axially relative to the winding jig 1111 so that the ejection mechanism 600 ejects the coil winding on the winding jig 1111 along the axial direction.

[0069] The winding ejection device for the axial flux motor coil winding utilizes multiple winding bobbins 1111 within the winding fixture 100 to provide support for the axial winding of the wire 2000. A drive module drives the wire 2000 to move arbitrarily within the winding fixture 100. Combined with a first hooking member 210 and a second hooking member within the hooking module, which can move arbitrarily within the space, the wire 2000 is hooked from the inside and outside of the winding fixture 100, respectively. This ensures that the winding nozzle 410, used for conveying the wire 2000, does not enter between adjacent winding bobbins 1111 within the winding fixture 100. Under the premise of gap, the wire 2000 is wound on the winding fixture 100. By making the ejector mechanism 600 have a first state fixedly connected to the hook module and a second state separated from the hook module, the ejector mechanism 600 in the first state is driven by the hook module to move axially, so that the ejector mechanism 600 can eject the coil winding completed in the winding fixture 100 from the winding fixture 100 along the axial direction. This makes full use of the existing structure in the hook module, without the need for an additional power source to drive the ejector mechanism 600 to move axially, reducing the required installation space and improving space utilization.

[0070] Combination Figures 2-4The specific structure of the ejection mechanism 600 is explained. The ejection mechanism 600 includes a first drive assembly 610, a connecting structure 620, and an ejection tray 630. The output end of the first drive assembly 610 is provided with a mating protrusion 611, and the hook module is provided with a mating seat 241. The first drive assembly 610 is configured to drive the mating protrusion 611 to be inserted and fixed into the mating groove 2411 in the mating seat 241. In the first state, the mating protrusion 611 in the ejection mechanism 600 is inserted and fixed into the mating groove 2411. In the second state, the mating protrusion 611 in the ejection mechanism 600 is separated from the mating groove 2411. The connecting structure 620 is fixedly connected to the first drive assembly 610. The ejection tray 630 is provided at one end of the winding trolley 1111 along the axial direction. The connecting structure 620 is movably connected to the ejection tray 630. The connecting structure 620 can abut against the ejection tray 630 along the axial direction and drive the ejection tray 630 to move along the axial direction. The ejection tray 630 is configured to abut against the coil winding.

[0071] By switching between the states of the first drive assembly 610 driving the mating protrusion 611 to be inserted and fixed with the mating groove 2411 of the mating seat 241 in the hook module and to be separated from each other, the ejection mechanism 600 achieves the effect of switching between the first state and the second state. By fixing the connecting structure 620 to the first drive assembly 610 and setting the ejection tray 630 at one end of the winding trolley 1111 along the axial direction, when the mating protrusion 611 is inserted and fixed with the mating groove 2411, the hook module can drive the first drive assembly 610 to move axially, thereby driving the connecting structure 620 to move axially, so that the connecting structure 620 abuts against the ejection tray 630 and continuously drives the ejection tray 630 to move axially relative to the winding trolley 1111, so as to eject the coil winding on the winding trolley 1111 axially. It should be noted that in this embodiment, the first drive assembly 610 includes a linear cylinder. The linear cylinder has a simple structure, is easy to disassemble and assemble, and has a sensitive response. In other embodiments, the first drive component 610 may also be a combination of a linear motor, a rotary motor and a lead screw and nut structure, or other linear drive structures; this embodiment does not impose specific limitations.

[0072] In this embodiment, as Figure 2 As shown, a first detection element 242 is provided inside the hook module. The first detection element 242 is communicatively connected to the hook module and is configured to detect whether the mating protrusion 611 is inserted and fixedly engaged with the mating groove 2411. By setting the first detection element 242 to detect whether the mating protrusion 611 is inserted and fixedly engaged with the mating groove 2411, the driving safety of the hook module to the ejection mechanism 600 can be ensured, and the normal operation of the winding ejection device of the axial flux motor coil winding can be guaranteed.

[0073] In addition, such as Figure 5As shown, a second detection element 6212 is provided on the connecting structure 620. The second detection element 6212 is communicatively connected to the hook module and is configured to detect whether the connecting structure 620 abuts against the ejector tray 630. By setting the second detection element 6212 to detect whether the connecting structure 620 abuts against the ejector tray 630, the abutment effect between the connecting structure 620 and the ejector tray 630 can be guaranteed, thereby ensuring the normal operation of the winding ejection device for the axial flux motor coil winding.

[0074] It should be noted that in this embodiment, both the first detection element 242 and the second detection element 6212 are laser sensors, which are communicatively connected to the hook module. Laser sensors have a simple structure, are easy to assemble and disassemble, and offer high detection accuracy. In other embodiments, the first detection element 242 and the second detection element 6212 can also be other types of detection structures; this embodiment does not impose specific limitations.

[0075] As an optional solution, such as Figure 3 and Figure 4 As shown, the ejection mechanism 600 also includes a guide plate 640. The winding fixture 100 is mounted on the end face of the guide plate 640. The connecting structure 620 includes a first connector 621 and a second connector 622 connected together. The second connector 622 is fixedly connected to the first drive assembly 610. The first connector 621 extends axially and can abut against the ejection tray 630. The guide plate 640 has an axially extending guide hole that slides with the first connector 621. By setting the winding fixture 100 and the ejection tray 630 on the guide plate 640 within the ejection mechanism 600, and by providing an axially extending guide hole within the guide plate 640, the first connector 621 in the connecting structure 620 slides with the guide hole, thus providing guidance for the axial movement of the connecting structure 620.

[0076] In one of the alternative solutions, such as Figure 6 and Figure 7 As shown, the winding fixture 100 includes a winding assembly 110 and a chassis 120. The chassis 120 is fixed on a guide plate 640. The winding assembly 110 is fixed on the radial end face of the chassis 120 away from the guide plate 640. The winding assembly 110 includes a winding structure 111 and a wire guide post 112. Multiple winding structures 111 are arranged in a circular sequence around the central axis of the chassis 120. Each winding structure 111 has wire guide posts 112 at both ends around the central axis of the chassis 120. The wire guide posts 112 are configured to construct a bridge wire. Each winding structure 111 includes three winding coils 1111 arranged in a sequential manner around the central axis of the chassis 120. The ejector tray 630 is located at one end of the chassis 120 away from the chassis 120 along the axial direction.

[0077] It should be noted that, in this embodiment, the ejector tray 630 is provided with a first clearance through hole 632 and a second clearance through hole 633 extending along the axial direction. The first clearance through hole 632 is used to accommodate the winding tube 1111, and the second clearance through hole 633 is used to accommodate the wire guide post 112. An ejection protrusion 631 is provided on the hole wall of the first clearance through hole 632, and the ejection protrusion 631 can abut against the coil.

[0078] In addition, to facilitate the contact between the ejector tray 630 and the first connector 621, the ejector tray 630 is provided with a contact protrusion 634 extending radially outward along the chassis 120, and the contact protrusion 634 is configured to contact the first connector 621.

[0079] To ensure that the ejector tray 630 can move axially and reset after ejecting the coil, such as Figure 5 As shown, a first magnet 6211 is provided at one end of the first connector 621 near the abutting protrusion 634. The first magnet 6211 is configured to abut against the abutting protrusion 634. The portion of the abutting protrusion 634 that is axially opposite to the first magnet 6211 is made of metal.

[0080] When the drive ejector tray 630 pushes the coil out of the winding kit 1111, the first drive assembly 610 drives the mating protrusion 611 to insert and fix with the mating groove 2411 in the mating seat 241 of the hook module. Then the hook module drives the first drive assembly 610 to move axially, thereby driving the first connector 621 to move axially, so that the first connector 621 abuts against the abutting protrusion 634. At this time, the first magnet 6211 is attracted and fixed to the abutting protrusion 634. After the ejector tray 630 completes ejecting the coil, the hook module drives the first drive assembly 610 to move in the opposite direction along the axial direction. Since the first magnet 6211 is attracted and fixed to the abutment protrusion 634, the first connector 621, driven by the first drive assembly 610, moves the ejector tray 630 in the axial direction until the ejector tray 630 abuts against the chassis 120. At this point, the hook module continues to drive the first drive assembly 610 to move in the opposite direction along the axial direction, and the attracted first magnet 6211 separates from the abutment protrusion 634 and continues to move in the axial direction. It should be noted that in other embodiments, a second magnet can also be provided in the portion of the abutment protrusion 634 directly opposite the first magnet 6211 in the axial direction, so that the second magnet and the first magnet 6211 attract each other.

[0081] like Figure 8As shown, in an alternative embodiment, the ejector tray 630 further includes an extension 635, which is disposed at one end of the partial ejector protrusion 631 away from the chassis 120 in the axial direction. The extension 635 extends in the axial direction and is configured to abut against the coil. In this embodiment, when the coil is wound on the winding trolley 1111, the individual coils may be positioned differently in the axial direction on the winding trolley 1111. When the ejector tray 630 simultaneously ejects multiple coils from their respective winding jigs 1111, the ejector protrusions 631 on the ejector tray 630 will first contact the coil closest to the ejector tray 630 along the axial direction. At this time, the remaining coils have not yet contacted the ejector protrusions 631. Only as the ejector tray 630 continues to move can the remaining coils be ejected from their respective winding jigs 1111. After the coils are ejected, the multiple coils are aligned along the axial direction, disrupting the relative positions of the coils along the axial direction. When the coils move axially relative to the other coils, they will inevitably pull on the bridge wires, thus affecting the arrangement of the bridge wires and consequently affecting the assembly of the subsequent coil windings and stator core. By additionally providing an axially extending extension 635 within the ejector tray 630, and positioning the extension 635 at the end of the ejector protrusion 631 that is axially away from the chassis 120, the extension 635 abuts against the coil. The extension distance of the extension 635 can be adjusted according to actual needs, so that during the ejection of the coil, the extension 635 and the ejector protrusion 631 simultaneously abut against the corresponding coil, allowing each coil to detach from the winding kit 1111 while maintaining a constant relative position along the central axial direction, further improving the ejection effect of the coil winding.

[0082] To further improve the driving effect of the hook module on the ejection mechanism 600, in this embodiment, two first connectors 621 are provided in the connecting structure 620. Both first connectors 621 are simultaneously fixedly connected to a second connector 622. Each first connector 621 corresponds to a guide hole and an abutment protrusion 634. In other embodiments, the specific number of first connectors 621 in the connecting structure 620 can be adjusted according to actual needs; this embodiment does not impose a specific limitation. Furthermore, in this embodiment, the ejection mechanism 600 includes two sets of first driving components 610 and two sets of connecting structures 620, with each set of first driving components 610 corresponding to one set of connecting structures 620. In other embodiments, the specific number of sets of first driving components 610 and connecting structures 620 in the ejection mechanism 600 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0083] In an alternative embodiment, such as Figure 1As shown, the hooking module includes a first hooking mechanism 200 and a second hooking mechanism 300. The first hooking mechanism 200 includes a first hooking member 210 and a first driving structure. The first hooking member 210 is located inside the winding fixture 100 and is connected to the first driving structure. The first driving structure can be fixedly connected to the ejection mechanism 600 in the first state. The first driving structure can drive the first hooking member 210 to move arbitrarily in space and drive the ejection mechanism 600 in the first state to move axially. The second hooking mechanism 300 includes a second hooking member and a second driving structure. The second hooking member is located outside the winding fixture 100 and is connected to the second driving structure. The second driving structure can drive the second hooking member to move arbitrarily in space. By driving the first hooking member 210, located inside the winding fixture 100, to move arbitrarily in space via the first driving structure within the first hooking mechanism 200, and driving the second hooking member, located outside the winding fixture 100, to move arbitrarily in space via the second driving structure within the second hooking mechanism 300, the first hooking member 210 and the second hooking member can respectively hook the wire 2000 from the inside and outside of the winding fixture 100. By driving the ejection mechanism 600, which is in the first state, to move axially via the first driving structure, the coil is ejected axially from the winding jig 1111.

[0084] Specifically, such as Figure 2 As shown, the first driving structure includes a second driving component 220, a third driving component 230, a transition platform 240, a fourth driving component 250, and a fifth driving component. The first hook member 210 is connected to the second driving component 220, and the second driving component 220 is configured to drive the first hook member 210 to move along a first direction. The second driving component 220 is connected to the fifth driving component, and the fifth driving component is configured to drive the second driving component 220 to move along a second direction. The fifth driving component is connected to the third driving component 230, and the third driving component 230 is configured to drive the fifth driving component to move around a third direction. The third driving component 230 is connected to the transition platform 240, and the transition platform 240 is connected to the fourth driving component 250. The fourth driving component 250 can drive the transition platform 240 to move along a third direction. The ejection mechanism 600 can be fixedly connected to the transition platform 240. The first direction, the second direction, and the third direction are perpendicular to each other in space, and the third direction is parallel to the axial direction.

[0085] It should be noted that in this embodiment, the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction. In other embodiments, the specific directions of the first, second, and third directions can be adjusted according to actual needs, and this embodiment does not impose specific limitations. Furthermore, in this embodiment, to simplify the structure of the first driving structure, the fifth driving component within the first driving structure is removed without affecting the normal hooking function of the first hooking component 210.

[0086] Furthermore, the second drive assembly 220, the fourth drive assembly 250, and the fifth drive assembly are all existing linear drive structures, and the third drive assembly 230 is an existing rotary drive structure. To keep the text concise, the specific structures of the second drive assembly 220, the third drive assembly 230, the fourth drive assembly 250, and the fifth drive assembly will not be described in detail here.

[0087] Understandably, the specific structure of the second drive structure is similar to that of the first drive structure. The only difference is that the second drive structure does not include the transfer platform 240 connected to the ejection mechanism 600. To keep the process simple, the specific structure of the second drive structure will not be described in detail here.

[0088] Optionally, such as Figure 1 As shown, the drive module includes a first drive mechanism 400 and a second drive mechanism 500. The first drive mechanism 400 is configured to transport the wire 2000 and drive the wire 2000 to move arbitrarily within space. The second drive mechanism 500 is connected to the winding fixture 100 and is configured to drive the winding fixture 100 to move arbitrarily within space. By having the first drive mechanism 400 transport the wire 2000 and drive it to move arbitrarily within space, and by having the second drive mechanism 500 drive the winding fixture 100 to move arbitrarily within space, the wire 2000 can be sequentially wound axially onto the winding jig 1111.

[0089] Specifically, such as Figure 9As shown, the first drive mechanism 400 includes a winding nozzle 410, a sixth drive assembly 420, a seventh drive assembly 430, and an eighth drive assembly 440. The winding nozzle 410 has a feeding port for the wire 2000 to pass through, and the wire 2000 wound on the spool is discharged along the feeding port. The sixth drive assembly 420 is connected to the winding nozzle 410 and can drive the winding nozzle 410 to move in a first direction. The seventh drive assembly 430 is connected to the sixth drive assembly 420 and can drive the sixth drive assembly 420 to move in a second direction. The eighth drive assembly 440 is connected to the seventh drive assembly 430 and can drive the seventh drive assembly 430 to move in a third direction. By sequentially connecting the winding nozzle 410, the sixth drive assembly 420, the seventh drive assembly 430, and the eighth drive assembly 440, the sixth drive assembly 420 drives the winding nozzle 410 to move along the first direction, the seventh drive assembly 430 drives the sixth drive assembly 420 to move along the second direction, and the eighth drive assembly 440 drives the seventh drive assembly 430 to move along the third direction. This ensures that the first direction, the second direction, and the third direction are perpendicular to each other in space, achieving the effect of driving the winding nozzle 410 to move arbitrarily in space. Combined with the fact that the winding nozzle 410 has a discharge port for the wire 2000, it can drive the wire 2000 to move arbitrarily in space, realizing the winding of the wire 2000 on the winding tube 1111, and meeting the actual winding requirements.

[0090] It should be noted that in this embodiment, the sixth drive component 420, the seventh drive component 430 and the eighth drive component 440 are all existing linear drive structures, and the specific structures of the sixth drive component 420, the seventh drive component 430 and the eighth drive component 440 will not be described in detail here.

[0091] Understandably, the specific structure of the second drive mechanism 500 is similar to that of the first drive mechanism 400, and will not be described in detail here.

[0092] In some embodiments, such as Figure 1 As shown, the winding ejection device for the axial flux motor coil winding also includes a wire clamping and cutting mechanism 700. The wire clamping and cutting mechanism 700 can clamp and fix the wire 2000 and cut the clamped wire 2000. By additionally equipping the winding ejection device for the axial flux motor coil winding with the wire clamping and cutting mechanism 700, the temporary clamping and fixing of the wire 2000 and its cutting can be achieved, improving the automation level of the winding ejection device for the axial flux motor coil winding. It should be noted that the specific structure and working principle of the wire clamping and cutting mechanism 700 are existing technologies and will not be described in detail here.

[0093] Optionally, such as Figure 1As shown, the winding ejection device for the axial flux motor coil winding also includes a tensioning mechanism 800. The tensioning mechanism 800 is disposed between the first drive mechanism 400 and the spool with the wire 2000 wound on it. The tensioning mechanism 800 is configured to tension the wire 2000 before it is conveyed to the first drive mechanism 400. By providing the tensioning mechanism 800 between the first drive mechanism 400 and the spool, the wire 2000 can be tensioned before it is discharged through the inner feed port of the winding nozzle 410, facilitating subsequent winding of the wire 2000. It should be noted that the specific structure and tensioning principle of the tensioning mechanism 800 are existing technologies and will not be described in detail here.

[0094] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
