Description

Technical Field

[0001] This utility model relates to the technical field of axial flux motor production equipment, and in particular to winding nozzles and winding devices. Background Technology

[0002] During the winding process of the axial flux motor coil winding, the winding nozzle is used to guide and transport the wire, and is driven by an external drive structure to move arbitrarily in space relative to the winding fixture, so that the wire is wound sequentially on the winding fixture and formed into a coil winding.

[0003] In related technologies, the winding nozzle has a transmission channel for the wire to pass through. When the winding nozzle moves arbitrarily in space relative to the winding fixture, a large deflection angle may occur between the wire extending out of the transmission channel and the wire located in the passage channel, causing compression and friction between the outer peripheral wall of the wire and the winding nozzle. This compression and friction between the wire and the winding nozzle can easily damage the wire. Specific manifestations include: scratches on the wire's insulation enamel, affecting insulation performance; excessive stretching of the wire leading to a reduction in cross-sectional area, affecting the wire's conductivity and mechanical strength; and deformation of the wire, affecting the winding effect of the coil.

[0004] Therefore, there is an urgent need to invent a winding nozzle and a winding device to solve the above problems. Utility Model Content

[0009] A winding nozzle body, wherein the winding nozzle body has a transmission through-hole for receiving wire; and

[0010] A pivot shaft is configured to rotatably connect the winding nozzle body and the connector within a preset angle about the axis of the pivot shaft.

[0011] As an optional solution, the preset angle is 40°;

[0012] The axis of the pivot shaft is parallel to the horizontal plane, with the vertical angle being 0°. The winding nozzle body can rotate relative to the connector within a range of -20° to 20° around the axis of the pivot shaft.

[0013] As an optional solution, the winding nozzle body is provided with multiple transmission through holes at intervals, the multiple transmission through holes extend in the same direction, and each transmission through hole is provided corresponding to a strand of wire.

[0014] As an optional solution, the winding nozzle body is provided with an extended protrusion, and the connector is provided with a receiving groove extending in a first direction and a first mating through hole extending in a second direction. The receiving groove is configured to receive the extended protrusion.

[0015] The outer protrusion has a second mating through hole, the first mating through hole passes through the receiving groove and is coaxially connected with the second mating through hole, the pivot shaft is simultaneously accommodated in the first mating through hole and the second mating through hole, the end of the winding nozzle body with the outer protrusion can abut against the end face of the connector with the receiving groove, and the first direction and the second direction are perpendicular to each other.

[0016] As an optional solution, the connector has a first end and a second end that are arranged opposite to each other. The first end is connected to the winding nozzle body and the pivot shaft, and the second end has a fixing through hole. The winding nozzle also includes a fixing member, which passes through the fixing through hole and is fixedly connected to the external drive structure.

[0017] As an optional solution, the fixed position of the connector and the external drive structure is adjustable along a third direction, which is the direction in which the first end and the second end are set opposite to each other.

[0018] A winding device includes a winding fixture, an external drive structure, and a winding nozzle as described above. The external drive structure is configured to drive the winding nozzle to move arbitrarily in space relative to the winding fixture, and the winding fixture provides winding support for the wire.

[0019] As an optional solution, the external driving structure includes:

[0020] A first driving mechanism, wherein the connecting member is connected to the output end of the first driving mechanism, and the first driving mechanism is capable of driving the connecting member to move along a fourth direction;

[0021] A second driving mechanism is provided, wherein the output end of the first driving mechanism is connected to the second driving mechanism, and the second driving mechanism is capable of driving the first driving mechanism to move along a fifth direction; and

[0022] The third driving mechanism is connected to the output end of the second driving mechanism.

[0027] The beneficial effects of this utility model are:

[0028] The winding nozzle provided by this utility model, by setting a transmission through hole in the main body of the winding nozzle, can guide the wire to be transported to the outside along the transmission through hole. By setting a pivot shaft, the connector and the main body of the winding nozzle are rotatably connected within a preset angle around the axis of the pivot shaft. Combined with the drive of the connector and the external drive structure, it is possible to realize arbitrary movement of the wire transported to the outside along the transmission through hole in space, and realize the winding of the wire on the winding fixture. Moreover, since the main body of the winding nozzle can rotate relative to the connector within a preset angle around the axis of the pivot shaft, when there is a deflection angle between the wire outside the transmission through hole and the wire inside the transmission through hole, the wire will automatically drive the main body of the winding nozzle to rotate relative to the connector around the axis of the pivot shaft, thereby eliminating the deflection angle between the wire outside the transmission through hole and the wire inside the transmission through hole, effectively reducing the squeezing and friction between the wire and the winding nozzle, and improving the protection of the wire. In addition, since the winding nozzle body can only rotate within a preset angle relative to the connecting member around the pivot shaft, it can also achieve stop positioning between the winding nozzle body and the connecting member, ensuring the normal guidance and delivery of the wire by the winding nozzle.

[0029] This invention also provides a winding device. By applying the aforementioned winding nozzle, when there is a deflection angle between the wire outside the transmission through-hole and the wire inside the transmission through-hole, the wire automatically drives the winding nozzle body to rotate axially relative to the connector around the pivot shaft. This eliminates the deflection angle between the wire outside the transmission through-hole and the wire inside the transmission through-hole, effectively reducing the squeezing and friction between the wire and the winding nozzle, and improving the protection of the wire. Furthermore, since the winding nozzle body can only rotate within a preset angle relative to the connector around the pivot shaft, it can also achieve stop positioning between the winding nozzle body and the connector, ensuring the normal guiding and conveying of the wire by the winding nozzle.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] This embodiment provides a winding device. For example... Figure 1 As shown, the winding device includes a winding fixture 500, an external drive structure, and a winding nozzle 100. The external drive structure is configured to drive the winding nozzle 100 to move arbitrarily in space relative to the winding fixture 500. The winding fixture 500 provides winding support for the wire 2000. The winding nozzle 100 is used to guide and transport the wire 2000. By cooperating with the external drive structure to drive the winding nozzle 100 to move arbitrarily in space relative to the winding fixture 500, the wire 2000 is wound sequentially on the winding fixture 500 to form a coil winding.

[0048] In the prior art, the winding nozzle 100 has a transmission channel for the wire 2000 to pass through. When the winding nozzle 100 moves arbitrarily in space relative to the winding fixture 500, a large deflection angle may occur between the wire 2000 extending out of the transmission channel and the wire 2000 located in the transmission through hole 111, causing compression and friction between the outer peripheral wall of the wire 2000 and the winding nozzle 100. The compression and friction between the wire 2000 and the winding nozzle 100 can easily damage the wire 2000. Specifically, this includes: scratches on the insulating varnish of the wire 2000, affecting its insulation performance; excessive stretching of the wire 2000, resulting in a reduction in cross-sectional area, affecting its conductivity and mechanical strength; and deformation of the wire 2000, affecting the winding effect of the coil winding.

[0049] To solve the above problems, such as Figure 2 and Figure 3As shown, this embodiment provides a winding nozzle 100. The winding nozzle 100 includes a winding nozzle body 110, a connector 120, and a pivot shaft 130. The connector 120 is fixedly connected to an external drive structure. The winding nozzle body 110 has a transmission through hole 111 for accommodating wire 2000. The pivot shaft 130 is configured to rotatably connect the winding nozzle body 110 and the connector 120 about the axial direction of the pivot shaft 130 within a preset angle.

[0050] The winding nozzle 100, by providing a transmission through hole 111 within the winding nozzle body 110, can guide the wire 2000 to be conveyed to the outside along the transmission through hole 111. A pivot shaft 130 is provided to connect the connector 120 and the winding nozzle body 110 to rotate within a preset angle around the axial direction of the pivot shaft 130. Combined with the drive of the connector 120 and the external drive structure, the wire 2000 conveyed to the outside along the transmission through hole 111 can be moved arbitrarily in space, enabling the wire 2000 to be wound on the winding fixture 500. Furthermore, because the winding nozzle body 110 can be positioned relative to the connector... The winding nozzle 100 rotates within a preset angle relative to the axial direction of the pivot shaft 130. When there is a deflection angle between the wire 2000 located outside the transmission through-hole 111 and the wire 2000 located inside the transmission through-hole 111, the wire 2000 automatically drives the winding nozzle body 110 to rotate axially relative to the connector 120 around the pivot shaft 130. This eliminates the deflection angle between the wire 2000 located outside the transmission through-hole 111 and the wire 2000 located inside the transmission through-hole 111, effectively reducing the squeezing and friction between the wire 2000 and the winding nozzle 100, and improving the protection of the wire 2000. In addition, since the winding nozzle body 110 can only rotate within a preset angle relative to the connector 120 around the pivot shaft 130, it can also achieve stop positioning between the winding nozzle body 110 and the connector 120, ensuring the normal guiding and conveying of the wire 2000 by the winding nozzle 100.

[0051] In this embodiment, the preset angle is 40°, the axis of the pivot shaft 130 is parallel to the horizontal plane, and the angle in the vertical direction is 0°. The winding nozzle body 110 can rotate relative to the connector 120 within the range of -20° to 20° around the axis of the pivot shaft 130. In other embodiments, the specific value of the preset angle can be adjusted according to actual needs, and a 0° reference can be established according to actual needs. This embodiment does not impose specific limitations.

[0052] To improve the current-carrying capacity of the axial flux motor, reduce AC damage, and improve heat dissipation, multiple strands of wire 2000 are simultaneously wound on the winding fixture 500 during the coil winding process. To meet the winding requirements of multiple strands of wire 2000, multiple transmission through holes 111 are spaced apart inside the winding nozzle body 110. The multiple transmission through holes 111 extend in the same direction, and each transmission through hole 111 corresponds to one strand of wire 2000. It should be noted that in this embodiment, the coil winding is formed by simultaneously winding five strands of wire 2000. Five transmission through holes 111 are spaced apart inside the winding nozzle body 110, and the five transmission through holes 111 extend in the same direction. In other embodiments, the number of transmission through holes 111 inside the winding nozzle body 110 can be adaptively adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0053] Combination Figures 2-4 The specific connection structure between the winding nozzle body 110, the connector 120, and the pivot shaft 130 is described below. The winding nozzle body 110 has an extended protrusion 112. The connector 120 has a receiving groove 121 extending in a first direction and a first mating through hole 122 extending in a second direction. The receiving groove 121 is configured to receive the extended protrusion 112. The extended protrusion 112 has a second mating through hole. The first mating through hole 122 passes through the receiving groove 121 and is coaxially connected to the second mating through hole. The pivot shaft 130 is simultaneously accommodated in both the first and second mating through holes. One end of the winding nozzle body 110 with the extended protrusion 112 can abut against the end face of the connector 120 with the receiving groove 121. The first and second directions are perpendicular to each other. By providing an extended protrusion 112 on the winding nozzle body 110 and a receiving groove 121 extending in the first direction on the connector 120, the extended protrusion 112 is accommodated. Combined with a first mating through hole 122 extending in the second direction on the connector 120 and a second mating through hole on the extended protrusion 112, the first mating through hole 122 passes through the receiving groove 121 and is coaxially connected to the second mating through hole. The pivot shaft 130 connects the first mating through hole 122 and the second mating through hole simultaneously, achieving the effect of axial rotation of the winding nozzle body 110 relative to the connector 120 around the pivot shaft 130.

[0054] Furthermore, when the extended protrusion 112 rotates axially relative to the connector 120 around the pivot shaft 130, the end of the winding nozzle body 110 with the extended protrusion 112 can abut against the end face of the connector 120 with the receiving groove 121, thereby stopping and positioning the winding nozzle body 110 relative to the connector 120 around the pivot shaft 130, ensuring that the winding nozzle body 110 can only rotate within a preset angle range relative to the connector 120 around the pivot shaft 130.

[0055] Specifically, in this embodiment, the preset angle is 40°, with the vertical angle as 0°, clockwise rotation as positive, and counterclockwise rotation as negative. The winding nozzle body 110 is located at the right end of the connector 120. For example, the winding nozzle body 110 can rotate relative to the connector 120 within a range of -20° to 20° around the pivot shaft 130. When the winding nozzle body 110 rotates clockwise relative to the connector 120 around the pivot shaft 130, and the lower left end of the winding nozzle body 110 abuts against the connector 120, the winding nozzle body 110 has rotated to a position of 20° relative to the connector 120 around the pivot shaft 130. When the winding nozzle body 110 rotates counterclockwise relative to the connector 120 about the pivot shaft 130, and the upper left end of the winding nozzle body 110 abuts against the connector 120, the winding nozzle body 110 rotates relative to the connector 120 about the pivot shaft 130 to a position of -20°.

[0056] It should be noted that in this embodiment, the first direction is the left-right direction, and the second direction is the front-back direction. In other embodiments, the specific directions of the first and second directions can be adjusted according to actual needs, and this embodiment does not impose specific limitations.

[0057] As an optional solution, such as Figure 2 and Figure 3 As shown, the connector 120 has a first end and a second end that are arranged opposite to each other. The first end is connected to the winding nozzle body 110 and the pivot shaft 130, and the second end has a fixing through hole 123. The winding nozzle 100 also includes a fixing member, which passes through the fixing through hole 123 and is fixedly connected to the external drive structure. By connecting the winding nozzle body 110 and the pivot shaft 130 to the first end of the connector 120 and the external drive structure to the second end, the structural feature of the first end and the second end being arranged opposite to each other is used to separate the winding nozzle body 110 from the external drive structure, thus avoiding interference between the winding nozzle body 110 and the external drive structure during subsequent operation.

[0058] Furthermore, the fixed position of the connector 120 and the external drive structure is adjustable along a third direction, which is the direction in which the first end and the second end are positioned relative to each other. By making the fixed position of the connector 120 and the external drive structure adjustable along a third direction, the relative position of the winding nozzle body 110 and the external drive structure along the third direction can be changed according to actual needs, further ensuring the normal operation of the winding device. It should be noted that in this embodiment, the third direction is the up-down direction. In other embodiments, the specific direction of the third direction can also be adaptively adjusted according to actual needs; this embodiment does not impose specific limitations.

[0059] Specifically, such as Figure 2 and Figure 3As shown, the second end has multiple fixing through holes 123 spaced apart along the third direction. When it is necessary to adjust the fixed position of the connector 120 and the external drive structure along the third direction, the fixing through holes 123 corresponding to the fixing member can be adjusted along the third direction.

[0060] In some embodiments, such as Figure 1 As shown, the external drive structure includes a first drive mechanism 200, a second drive mechanism 300, and a third drive mechanism 400. The connector 120 is connected to the output end of the first drive mechanism 200, and the first drive mechanism 200 can drive the connector 120 to move along the fourth direction. The first drive mechanism 200 is connected to the output end of the second drive mechanism 300, and the second drive mechanism 300 can drive the first drive mechanism 200 to move along the fifth direction. The second drive mechanism 300 is connected to the output end of the third drive mechanism 400, and the third drive mechanism 400 can drive the second drive mechanism 300 to move along the sixth direction. The fourth, fifth, and sixth directions are perpendicular to each other in space. By sequentially connecting the connector 120 to the output end of the first driving mechanism 200, connecting the first driving mechanism 200 to the output end of the second driving mechanism 300, and connecting the second driving mechanism 300 to the output end of the third driving mechanism 400, the first driving mechanism 200 drives the connector 120 to move along the fourth direction, the second driving mechanism 300 drives the first driving mechanism 200 to move along the fifth direction, and the third driving mechanism 400 drives the second driving mechanism 300 to move along the sixth direction. This ensures that the fourth, fifth, and sixth directions are mutually perpendicular in space, achieving the effect of allowing the connector 120 and the winding nozzle body 110 to move arbitrarily in space, thus meeting actual winding requirements. It should be noted that in this embodiment, the fourth direction is the up-down direction, the fifth direction is the left-right direction, and the sixth direction is the front-back direction. In other embodiments, the specific directions of the fourth, fifth, and sixth directions can be adaptively changed according to actual needs; this embodiment does not impose specific limitations.

[0061] In this embodiment, the first drive mechanism 200 includes a first drive member 210 and a first adapter 220; the second drive mechanism 300 includes a second drive member 310 and a second adapter 320; and the third drive mechanism 400 includes a third drive member 410 and a third adapter 420. A connector 120 is connected to the first adapter 220. The first adapter 220 is connected to the output end of the first drive member 210. The first drive member 210 is connected to the second adapter 320. The second adapter 320 is connected to the output end of the second drive member 310. The second drive member 310 is connected to the third adapter 420. The third adapter 420 is connected to the output end of the third drive member 410. It should be noted that in this embodiment, the first drive member 210, the second drive member 310, and the third drive member 410 are all existing linear drive structures, and for the sake of brevity, they will not be described in detail here.

[0062] Optionally, the winding device further includes a wire clamping and cutting mechanism 600, which is configured to clamp and fix the wire 2000 and cut the clamped wire 2000. By additionally equipping the wire clamping and cutting mechanism 600 to clamp and fix the wire 2000 and cut the clamped wire 2000, the completed coil winding and the wire 2000 can be cut and separated, improving the automation level of coil winding production. It should be noted that the specific structure and working principle of the wire clamping and cutting mechanism 600 are existing technologies and will not be described in detail here.

[0063] In an optional embodiment, the winding device further includes a tensioning mechanism 700, which is disposed between the winding nozzle 100 and the spool on which the wire 2000 is wound. The tensioning mechanism 700 is configured to tension the wire 2000, and the winding nozzle 100 can output the tensioned wire 2000 through the transmission through-hole 111. By setting the tensioning mechanism 700 to tension the wire 2000 before it enters the transmission through-hole 111 of the winding nozzle 100, the winding effect of the subsequent wire 2000 can be improved.

[0064] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
