FIG. 4 is a flowchart showing an example of a method for manufacturing the motor 1 according to the embodiment of the present invention.

  When the assembly of the motor 1 is started (start of FIG. 4), a step of preparing the stator 10 shown in FIG. 3 is executed in step # 101. In this step, the stator 10 having the lead wire 21 in which the first straight portion 21b and the second straight portion 21c are formed is prepared and placed on a mounting table (not shown) of the lead wire positioning device 100 (see FIG. 5).

  In step # 102, the step of arranging the inner positioning member of the leader line 21 is executed. In this step, the inner positioning member 110 is inserted into all the plurality of lead lines 21 up to the center axis CL of each of them (see FIGS. 9 and 10).

  In step # 103, a step of positioning the leader line 21 is executed. In this step, the leader line 21 is positioned between the inner positioning member 110 and the outer positioning member 120 (see FIG. 12).

  In step # 104, a step of preparing the support member mounting device 200 (see FIG. 19) is executed. In this step, a support member mounting device 200 for mounting the support member 30 of the lead wire 21 on the stator 10 is prepared and disposed on the upper side in the axial direction of the stator 10 (see FIG. 22).

  In step # 105, a step of causing the support member mounting device 200 to approach the stator 10 is executed. In this step, the support member mounting device 200 provided with the through hole 202a through which the lead wire 21 passes is lowered along the axial direction. And the supporting member mounting apparatus 200 is made to approach the stator 10 to the position where each leader line 21 is inserted in the through hole 202a (see FIG. 23).

  In step # 106, a step of separating the support member mounting apparatus 200 from the stator 10 is executed. In this step, the support member mounting device 200 is lifted along the axial direction and once separated from the stator 10. At this time, the support member mounting device 200 in which the leader line 21 is inserted into the through hole 202a is separated from the stator 10 to a position where each of the leader lines 21 is removed from the through hole 202a (see FIG. 24).

  In step # 107, a process of holding the lead wire support member 30 in the support member mounting apparatus 200 is executed. In this step, the lead wire support member 30 is held on the stator 10 side of the support member mounting device 200 (see FIG. 24).

  In step # 108, a step of attaching the lead wire support member 30 to the stator 10 is executed. In this step, the support member mounting device 200 is lowered along the axial direction and again approaches the upper side in the axial direction of the stator 10, and the lead wire support member 30 is mounted on the stator 10. At this time, the lead wire support member 30 is mounted on the stator 10 with each of the lead wires 21 accommodated in the support portion 31 (see FIGS. 25 and 26).

The leader line 21 is a state in which the formation of the first straight portion 21b and the second straight portion 21c is completed. The second straight portion 21c extends substantially linearly upward along the axial direction.

<2-2. Arrangement process of inner positioning member>
FIG. 6 is a plan view of the insertion member 130 of the leader line positioning device 100 used in the method for manufacturing the motor 1 according to the embodiment of the present invention. FIG. 7 is a partially enlarged plan view of the insertion member 130 of the leader line positioning device 100 used in the method for manufacturing the motor 1 according to the embodiment of the present invention. FIG. 8 is a plan view of the insertion member 130 showing a positioning state of the inner positioning member 110 of the leader line positioning device 100 used in the method for manufacturing the motor 1 according to the embodiment of the present invention. FIG. 9 is a plan view showing a first stage of the arrangement step of the inner positioning member 110 in the method for manufacturing the motor 1 according to the embodiment of the present invention. FIG. 10 is a plan view showing a second stage of the arrangement step of the inner positioning member 110 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  The leader line positioning device 100 includes an inner positioning member 110 shown in FIG. 5 in addition to the mounting table.

  The inner positioning member 110 is arranged on the outer side in the radial direction of the stator 10 in the stage before the positioning of the lead wire 21. For example, four inner positioning members 110 are provided. Two inner positioning members 110 are provided in each of the pair of insertion members 130. That is, in the leader line positioning device 100, two pairs of the insertion members 130 are used. The pair of insertion members 130 can be moved in a direction approaching and separating from the lead wire 21 and the insertion member 130 can be rotated by a moving mechanism (not shown).

  As shown in FIGS. 5 and 6, the pair of insertion members 130 has a so-called bowl shape, and can rotate around a support shaft 131 that extends in the axial direction. The insertion member 130 extends along the radial direction of the stator 10 in a state where the regions corresponding to the two blades of the collar are closed. The inner positioning member 110 is disposed at the distal end portion of the insertion member 130 on the radially inner side of the stator 10. Two inner positioning members 110 are individually provided in regions corresponding to the two blades of the scissors of the insertion member 130. The inner positioning member 110 can be rotated together with the insertion member 130 around the support shaft 131 arranged on the outer side in the radial direction (see FIG. 8).

  Each of the four inner positioning members 110 has three recesses 111 individually. The concave portion 111 is provided in a region facing the leader line 21 of the inner positioning member 110 when the inner positioning member 110 is disposed on the center axis CL side with respect to the leader line 21, and extends along a direction intersecting the axial direction. Indented in a direction away from the leader line 21. The recess 111 has a shape and size that can receive the lead wire 21.

  The recess 111 can contact the lead wire 21 from the center axis CL side of the lead wire 21. Furthermore, since the inner positioning member 110 has the three recessed portions 111, the inner positioning member 110 comes into contact with the three lead wires 21 from the central axis CL side of the lead wire 21. The three recesses 111 provided in the single inner positioning member 110 clearly define the interval and positional relationship of the three lead lines 21 in the direction intersecting the axial direction. According to this configuration, the number of parts can be reduced as compared with a configuration in which each of the twelve recesses 111 is provided independently. In addition, the workability related to the arrangement of the inner positioning member 110 can be improved.

  As shown in FIGS. 6 and 7, the inner positioning member 110 includes a radial inner positioning member 110A and a circumferential inner positioning member 110B. The radially inner positioning member 110A and the circumferential inner positioning member 110B are arranged side by side in the axial direction. Each of the radially inner positioning member 110A and the circumferential inner positioning member 110B has recesses 111A and 111B at the same position in the direction intersecting the axial direction. The recess 111 includes a recess 111A and a recess 111B.

  The radially inner positioning member 110 </ b> A is configured as the same member as the insertion member 130. The radially inner positioning member 110A has three recesses 111A. The recess 111A has a curved wall surface that is gentler than the recess 111B of the circumferential inner positioning member 110B, for example, an arc-shaped wall surface. The radially inner positioning member 110A performs the radial positioning of the lead wire 21 by the recess 111A having this shape.

  The circumferential inner positioning member 110B is arranged in contact with the axially lower surface of the radial inner positioning member 110A. The circumferential inner positioning member 110B has three concave portions 111B. The recess 111B has a curved wall surface that is steeper than the recess 111A of the radially inner positioning member 110A, for example, a V-shaped wall surface. The circumferential inner positioning member 110B positions the leader line 21 in the circumferential direction by the concave portion 111B having this shape.

  The inner positioning member 110 positions the lead wire 21 in the radial direction and the circumferential direction by the recesses 111A and 111B. By combining the radially inner positioning member 110A and the circumferential inner positioning member 110B, the lead wire 21 can be positioned at an appropriate position.

  In addition, although a pair of insertion member 130 mutually cross | intersects and rotates, the structure which does not cross | intersect may be sufficient. The pair of insertion members 130 may be in contact with each other or may be non-contact. Further, the radially inner positioning member 110 </ b> A may be configured as a separate member of the insertion member 130. The circumferential inner positioning member 110B may be configured as the same member as the insertion member 130.

  In the arrangement step of the inner positioning member 110, the inner positioning member 110 is pulled out through the gap G provided between the adjacent lead wires 21 with the pair of insertion members 130 closed as shown in FIG. The wire 21 is inserted from the radially outer side of the stator 10 on the center axis CL side. Two gaps G through which each of the two pairs of insertion members 130 passes individually are arranged at positions to be pointed with respect to the central axis CL. The two gaps G are wider in the direction intersecting the axial direction than other gaps through which the pair of insertion members 130 do not pass.

  And a pair of said insertion member 130 is mutually rotated when mutual inner positioning member 110 is inserted and extracted with respect to the central axis CL side of the leader line 21, and the inner positioning member 110 of each other is rotated. Approached. According to this configuration, the two inner positioning members 110 can be arranged side by side with the pair of insertion members 130 so that the longitudinal directions thereof are substantially parallel to each other. Therefore, the inner positioning member 110 can be reduced in size. Therefore, it is possible to pass the inner positioning member 110 between adjacent leader lines 21 that are relatively narrow.

  Subsequently, as shown in FIG. 10, the inner positioning member 110 moves each of the two inner positioning members 110 radially outward by opening a so-called hook of the pair of insertion members 130. In the inner positioning member 110, the three concave portions 111 move radially outward toward the lead wire 21. In the inner positioning member 110, the three concave portions 111 come into contact with the three lead wires 21 from the center axis CL side of the lead wire 21. In other words, the pair of insertion members 130 are rotated with each other when the inner positioning members 110 are in contact with the lead wires 21, and the inner positioning members 110 are separated from each other. According to this configuration, by opening an area corresponding to each of the two blades of the scissors of the pair of insertion members 130 configured in a so-called scissor shape, the inner positioning member 110 on the center axis CL side of the leader line 21 is formed. Easy to move.

  The outer positioning member 120 is arranged on the outer side in the radial direction of the stator 10 in the stage before the positioning of the lead wire 21. For example, four outer positioning members 120 are provided in the same number as the inner positioning members 110. The four outer positioning members 120 are arranged side by side at a predetermined interval in the circumferential direction. The outer positioning member 120 can be moved in a direction approaching and separating from the lead wire 21 by a moving mechanism (not shown).

  Each of the four outer positioning members 120 has three recesses 121 individually. The recess 121 is provided in a region of the outer positioning member 120 facing the lead line 21 and is recessed in a direction away from the lead line 21 along a direction intersecting the axial direction. The recess 121 has a shape and size that can receive the lead wire 21.

  Each of the four outer positioning members 120 has a substantially rectangular shape extending in the radial direction of the stator 10 in plan view. Further, each of the four outer positioning members 120 can move in a direction in which a substantially central portion in the circumferential direction of the stator 10 approaches and separates from the lead wire 21 along the radial direction of the stator 10. .

  The recess 121 can contact the lead line 21 from the opposite side of the lead line 21 with respect to the central axis CL. Since the outer positioning member 120 has the three recesses 121, the outer positioning member 120 comes into contact with the three lead wires 21 from the opposite side of the lead wire 21 with respect to the central axis CL. The three recesses 121 provided in the single outer positioning member 120 clearly define the interval and positional relationship of the three lead lines 21 in the direction intersecting the axial direction. According to this configuration, the number of parts can be reduced as compared with a configuration in which each of the twelve recesses 121 is provided independently. In addition, the workability related to the arrangement of the outer positioning member 120 can be improved.

  As shown in FIG. 11, the outer positioning member 120 includes a radial outer positioning member 120A and a circumferential outer positioning member 120B. The radially outer positioning member 120A and the circumferential outer positioning member 120B are arranged side by side in the axial direction. Each of the radially outer positioning member 120A and the circumferential outer positioning member 120B has recesses 121A and 121B at the same position in the direction intersecting the axial direction. The recess 121 includes a recess 121A and a recess 121B.

  The radially outer positioning member 120A has one recess 121A. The recess 121A has a curved wall surface that is gentler than the recess 121B of the outer circumferential positioning member 120B, for example, an arc-shaped wall surface. The radially outer positioning member 120A positions the leader line 21 in the radial direction by the recess 121A having this shape.

  The circumferential outer positioning member 120B is disposed in contact with the axially upper surface of the radial outer positioning member 120A. The circumferential direction outer positioning member 120B has three recesses 121B. The recess 121B has a curved wall surface that is steeper than the recess 121A of the radially outer positioning member 120A, for example, a V-shaped wall surface. The circumferential outer positioning member 120B positions the leader line 21 in the circumferential direction by the concave portion 121B having this shape.

  The outer positioning member 120 positions the lead wire 21 in the radial direction and the circumferential direction by the recesses 121A and 121B. By combining the radially outer positioning member 120A and the circumferential outer positioning member 120B, the leader line 21 can be positioned at an appropriate position.

  In the step of positioning the lead wire 21, the outer positioning member 120 approaches the lead wire 21 from the radially outer side of the stator 10 toward the central axis CL as shown in FIG. In the outer positioning member 120, the three concave portions 121 come into contact with the three lead wires 21 from the side opposite to the center axis CL of the lead wire 21. As a result, the twelve lead lines 21 are individually sandwiched between the recess 111 of the inner positioning member 110 and the recess 121 of the outer positioning member 120 and are positioned at appropriate positions. Therefore, the leader line positioning device 100 can efficiently arrange the leader lines 21 at predetermined positions, and the motor 1 can be manufactured in a short time.

  The inner positioning member 110 is in contact with a single lead wire 21 from the center axis CL side of the lead wire 21, and the outer positioning member 120 is a single lead wire 21 with a plurality of lead wires 21. Contact is made from the opposite side to the central axis CL, and the number of the respective leader lines 21 is three. According to this configuration, when the leader line 21 is sandwiched between the inner positioning member 110 and the outer positioning member 120, it is possible to suppress the occurrence of positional deviation of the leader line 21.

  The opening side of the recess 111 of the inner positioning member 110 and the opening side of the recess 121 of the outer positioning member 120 overlap in the axial direction. The recesses 111 and 121 have a larger opening width and depth with respect to the wire diameter of the leader line 21, so that even when the leader line 21 before positioning is relatively largely deviated from a predetermined position, the recesses 111 and 121. It becomes easy to accommodate. Further, by making the opening side of the recess 111 and the opening side of the recess 121 overlap in the axial direction, the area surrounded by the recesses 111 and 121 can be reduced, and the leader line 21 is held between the recesses 111 and 121. Can do. Thereby, even when the lead line 21 before positioning is relatively largely deviated from the predetermined position, it is possible to correct the misalignment with high accuracy.

  When the positioning of the leader line 21 is completed, as shown in FIG. 13, the inner positioning member 110 and the outer positioning member 120 are arranged with respect to the leader line 21. The inner positioning member 110 and the outer positioning member 120 are disposed at different heights in the axial direction.

  According to this configuration, the opening width and depth of the recesses of the recess 111B of the circumferential inner positioning member 110B and the recess 121B of the circumferential outer positioning member 120B can be increased. Thereby, even when the leader line 21 before positioning is relatively deviated from the predetermined position, the leader line 21 can be easily accommodated in the recesses 111B and 121B, and the leader line 21 can be easily moved to the predetermined position. . Moreover, according to this structure, the contact in the direction which cross | intersects the axial direction of the inner side positioning member 110 and the outer side positioning member 120 can be avoided. Thereby, it becomes easy to arrange a mechanism for moving the inner positioning member 110 and the outer positioning member 120.

  Further, the inner positioning member 110 and the outer positioning member 120 have different axial heights and overlap in the axial direction in plan view. Thereby, the closed region surrounded by the concave portion 111B and the concave portion 121B in plan view can be made smaller as the inner positioning member 110 and the outer positioning member 120 approach each other. Therefore, the leader line 21 can be gripped by the inner positioning member 110 and the outer positioning member 120, and the positioning accuracy of the leader line 21 can be improved.

  Further, with respect to the four outer positioning members 120 in a positioning state with respect to the lead wire 21, a gap S is generated between the adjacent outer positioning members 120 above the outer edge portion of the stator 10. The gap S is formed in a fan shape in plan view, and there are four places. Of the four gaps S, the pair of insertion members 130 pass through the two gaps S, and the leg portions 32 of the lead wire support members 30 are located in the two gaps S, respectively. Since the gap S in which the leg portion 32 is located is different from the gap S through which the pair of insertion members 130 passes, the operation of the leader line positioning device 100 is not hindered.

FIG. 22 is a perspective view showing a preparation process of the support member mounting apparatus 200 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the drawings used in the following description, drawing of the leader line positioning device 100, that is, the inner positioning member 110 and the outer positioning member 120 is omitted. The inner positioning member 110 and the outer positioning member 120 continue to position the lead wire 21 until the lead wire support member 30 is attached to the stator 10.

  As illustrated in FIG. 19, the support member mounting device 200 includes a base portion 201, a floating plate 202, a holding portion 203, and a suction portion 204.

  The base part 201 is supported by a moving mechanism (not shown). The support member mounting device 200 can be moved in a direction approaching and separating from the stator 10 by a moving mechanism. The support member mounting device 200 approaches and separates from the stator 10 along the axial direction on the upper side in the axial direction of the stator 10.

  The base part 201 has a circular opening 201a. The opening 201a is provided in the central portion in the radial direction. The opening 201a has an inner diameter larger than the outer diameter of the stator 10, and can pass the stator 10 along the axial direction. The base part 201 is provided with a holding part 203. The base part 201 supports the floating plate 202 via the holding part 203.

  The floating plate 202 is disposed above the base portion 201. A part of the floating plate 202 faces the stator 10 through the opening 201a. The floating plate 202 is supported by the base unit 201 via the holding unit 203. The floating plate 202 can move relative to the base portion 201 in a direction intersecting the axial direction in a state where the holding by the holding portion 203 is released.

  The floating plate 202 has a plurality of through holes 202a shown in FIGS. The through hole 202a extends along the axial direction. The through holes 202a are provided in the same number as the leader lines 21, that is, twelve, and each leader line 21 passes individually. The twelve through-holes 202a are arranged in the same arrangement as a support portion 31 of a leader line support member 30 described later in a plane intersecting the axial direction as a whole. The upper part of the through hole 202a is cylindrical. Similarly to the support portion 31 of the lead wire support member 30, the through hole 202a may have a shape obtained by dividing a cylinder along the axial direction.

  The through hole 202a has an inclined portion 202b shown in FIGS. The inclined portion 202b is provided at the lower portion of the floating plate 202 and at the entrance of the lead wire 21 of the through hole 202a. The inclined portion 202b is configured with an inclination that the insertion path of the leader line 21 becomes wider toward the upstream side in the insertion direction of the leader line 21, that is, the lower side in the axial direction.

  The holding unit 203 is provided on the base unit 201. The holding unit 203 can hold and release the floating plate 202. In the holding state by the holding unit 203, the floating plate 202 is prevented from moving. In a state in which the holding unit 203 releases the holding state, the floating plate 202 can freely move in a direction intersecting the axial direction.

  The suction unit 204 is provided on the floating plate 202. The suction unit 204 is a mechanism for attaching and detaching a later-described leader line support member 30 by air pressure to the lower side of the floating plate 202. According to this configuration, the leader line support member 30 can be easily attached to and detached from the support member mounting device 200.

  In the preparation process of the support member mounting device 200, the support member mounting device 200 is disposed on the upper side in the axial direction of the stator 10, as shown in FIG. Although drawing is omitted in FIG. 22, the leader line 21 is positioned by the inner positioning member 110 and the outer positioning member 120. At this time, the holding unit 203 brings the floating plate 202 into a holding release state. That is, the floating plate 202 can freely move in a direction intersecting the axial direction.

<2-5. Accessing Step of Supporting Member Mounting Device to Stator>
FIG. 23 is a perspective view showing a process of approaching the stator 10 of the support member mounting device 200 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the approaching process of the support member mounting device 200 to the stator 10, the support member mounting device 200 shown in FIG. 22 is lowered along the axial direction toward the stator 10 by the moving mechanism. Then, as shown in FIG. 23, the support member mounting device 200 approaches the stator 10 to a position where each of the lead wires 21 is inserted into the through hole 202a.

  Until the support member mounting device 200 is adjacent to the stator 10, the holding unit 203 brings the floating plate 202 into a release state. That is, the floating plate 202 can freely move until the leader line 21 is inserted into the through hole 202a. According to this configuration, since the leader line 21 is positioned by the inner positioning member 110 and the outer positioning member 120, the support member mounting device 200 is based on the position information of the leader line 21 positioned by the leader line positioning device 100. The floating plate 202 can be moved while being controlled. Therefore, the leader line 21 can be easily inserted into the through hole 202a. Even if at least one position of the leader line 21 or the floating plate 202 is shifted, the inclined portion 202b of the through hole 202a can be inserted by centering the tip of the leader line 21 at the center of the through hole 202a. . In addition, since the floating plate 202 is held so as to be freely movable, the lead wire 21 can be easily inserted into the through hole 202a if the positional deviation is within the movable range of the floating plate 202. In this manner, each of the 12 lead lines 21 can be inserted into the through hole 202a of the floating plate 202 in consideration of a slight positional shift. Further, by passing the displaced lead wire 21 through the through hole 202a, the lead wire 21 can be slightly plastically deformed to correct the posture of the lead wire 21.

  As shown in FIG. 23, when the support member mounting device 200 is adjacent to the stator 10, the holding unit 203 holds the floating plate 202. That is, the floating plate 202 is held by the holding portion 203 after the leader line 21 is inserted into the through hole 202a, and its movement is prevented. According to this configuration, when the support member mounting device 200 is adjacent to the stator 10, each of the 12 lead wires 21 can be held at a predetermined position as a whole. The support member mounting apparatus 200 stores position information of the leader line 21 when the leader line 21 is inserted into the through hole 202a.

<2-6. Step of separating support member mounting device from stator>
FIG. 24 is a perspective view illustrating a step of separating the support member mounting apparatus 200 from the stator 10 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the step of separating the support member mounting device 200 from the stator 10, the support member mounting device 200 shown in FIG. 23 is raised along the axial direction with respect to the stator 10 by the moving mechanism. Then, as shown in FIG. 24, the support member mounting device 200 is temporarily separated from the stator 10 to a position where each of the lead wires 21 is disengaged from the through hole 202a.

  The holding unit 203 keeps the floating plate 202 in the holding state. And the leader line support member 30 is prepared.

  As shown in FIG. 24, the lead wire support member 30 has an annular shape whose central axis extends in the axial direction (vertical direction). The lead wire support member 30 has a circular opening 30a. The opening 30a is provided at a substantially central portion in the radial direction. The lead wire support member 30 includes a plurality of support portions 31 and a plurality of leg portions 32.

  The support part 31 is provided along the circumference of the opening 30a. The same number of support portions 31 as the leader lines 21, that is, 12 support portions 31 are arranged at predetermined positions. The support portion 31 has a shape obtained by dividing a cylinder along the axial direction. The support part 31 has a groove-shaped accommodation part 31a extending in the axial direction. In addition, you may comprise the support part 31 in a perfect cylindrical shape. The support part 31 individually accommodates and supports each of the plurality of lead wires 21 in the accommodating part 31a.

  A plurality of the leg portions 32 are provided on the outer peripheral portion of the lower surface of the lead wire support member 30. The leg portion 32 extends downward. The leg portion 32 has a shape and size that fits into the groove portion 12 b provided on the upper outer peripheral portion of the insulator 12.

<2-7. Lead wire support member holding step>
FIG. 25 is a perspective view showing a holding process of the lead wire support member 30 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the holding process of the lead wire support member 30, the lead wire support member 30 is held on the stator 10 side of the support member mounting device 200 as shown in FIG. A suction unit 204 provided on the floating plate 202 is used to hold the lead wire support member 30.

  The leader line support member 30 is attracted to the suction portion 204 in a state where the upper end position of the support portion 31 is matched with the lower end position of the through hole 202a of the floating plate 202, whereby the support member mounting device 200 Retained. Note that the inner diameter of the lower side of the through hole 202a is larger than the size of the lower side of the accommodating part 31a of the support part 31. According to this configuration, it is easy to insert the leader line 21 into the through hole 202a.

<2-8. Mounting process of lead wire support member to stator>
FIG. 26 is a perspective view showing a process of mounting the lead wire support member 30 to the stator 10 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the mounting process of the leader line support member 30 to the stator 10, as shown in FIG. 26, the support member mounting apparatus 200 is lowered along the axial direction while holding the leader line support member 30 on the lower side. It approaches again to the upper side of the stator 10 in the axial direction. In the lead wire support member 30, the position of the accommodating portion 31a of the support portion 31 coincides with the position of the through hole 202a. That is, the positions of the accommodating portions 31 a of the twelve support portions 31 coincide with the positions of the twelve leader lines 21.

  According to the above-described support member mounting method, the lead wire positioning device 100 and the support member mounting device 200 are mounted immediately before the lead wire support member 30 that supports the lead wire 21 extending from the coil portion 13 is mounted on the stator 10. The leading end portion of the lead wire 21 can be efficiently adjusted to a predetermined position by using it, and the lead wire support member 30 can be easily attached to the stator 10. In addition, before the lead wire support member 30 is mounted on the stator 10, the lead wire 21 is in a state where the lead wire 21 is largely displaced by passing the support member mounting device 200 adjacent to the stator 10. It is possible to detect the member 30 before mounting it on the stator 10.

  The lead wire support member 30 is held by the support member mounting device 200 after the lead wire 21 is inserted into the through hole 202 a and separated from the stator 10, and each lead wire 21 is accommodated in the support portion 31. The stator 10 is attached. The leader line 21 is accommodated in the support part 31 based on the positional information of the leader line 21 memorize | stored by the support member mounting apparatus 200, when the leader line 21 is inserted in the through-hole 202a. The That is, since each leader line 21 has been confirmed to pass through the through hole 202a of the floating plate 202 before the lead wire support member 30 mounting process, the leader line support member 30 is placed at the same position as the floating plate 202. If it moves, each leader line 21 can be easily accommodated in each support part 31. Based on the position information of the leader line 21 of the support member mounting device 200, each leader line 21 can be positioned and accommodated in more detail with respect to each support part 31. For example, when the leader line 21 is disengaged from the through hole 202a of the floating plate 202, the position of the leader line 21 may be shifted by the spring back. It is possible to adjust the position of the leader line support member 30 in consideration of the position variation. Therefore, according to this configuration, the lead wire 21 can be more easily accommodated in the support portion 31 of the lead wire support member 30.

  And the leg part 112 fits into the groove part 12b of the insulator 12. FIG. Thereby, the mounting of the lead wire support member 30 to the stator 10 is completed.

<2-9. Retraction process of support member mounting device>
FIG. 27 is a perspective view showing a retracting process of the support member mounting apparatus 200 in the method for manufacturing the motor 1 according to the embodiment of the present invention.

  In the retracting process of the support member mounting device 200, the holding of the lead wire support member 30 by the suction unit 204 is released. Then, as shown in FIG. 27, the support member mounting device 200 is retracted away from the upper side in the axial direction of the stator 10 toward the upper side.

<2-10. Positioning member retracting process>
In the positioning member retracting step, the inner positioning member 110 and the outer positioning member 120 are retracted from the axially upper side of the stator 10. The inner positioning member 110 closes a so-called hook-shaped region of the pair of insertion members 130 and passes between the adjacent lead wires 21 from the center axis CL side of the lead wire 21 to the radially outer side of the stator 10. It is pulled out and evacuated. The outer positioning member 120 is retracted toward the radially outer side of the stator 10 from the side opposite to the center axis CL of the lead wire 21.

<3-1. First Modified Example of Leader Positioning Device>
Next, a first modification of the leader line positioning device will be described. FIG. 28 is a plan view showing a lead wire positioning state of a first modification of the lead wire positioning device used in the method for manufacturing a motor according to the embodiment of the present invention. Since the basic configuration of this embodiment is the same as that of the leader line positioning device 100 described above, the same reference numerals or the same names are assigned to the same components as those of the leader line positioning device 100. The description may be omitted.

  The leader line positioning device 300 of the first modification has an inner positioning member 110 and an outer positioning member 320 as shown in FIG.

  Unlike the four inner positioning members 110, three outer positioning members 320 (3201, 3202, 3203) are provided. The three outer positioning members 320 are arranged at predetermined intervals in the circumferential direction.

  The first outer positioning member 3201 has six recesses 321. Each of the second outer positioning member 3202 and the third outer positioning member 3203 has three concave portions 321 individually. The second outer positioning member 3202 and the third outer positioning member 3203 are adjacent to each other in the circumferential direction. The first outer positioning member 3201 is disposed on the opposite side of the center axis CL with respect to the second outer positioning member 3202 and the third outer positioning member 3203.

  Each of the three outer positioning members 320 has a substantially rectangular shape extending in the radial direction of the stator 10 in plan view. Further, each of the three outer positioning members 320 can move in a direction in which a substantially central portion in the circumferential direction of the stator 10 approaches and separates from the lead wire 21 along a substantially radial direction of the stator 10. is there. Thereby, the recessed part 321 can contact the leader line 21 from the opposite side to the central axis CL of the leader line 21.

The gap S is formed in a fan shape in plan view, and there are three locations (S1, S2, S3).

  Of the three gaps S, the leg portion 32 of the lead wire support member 30 is located in the gap S3 between the second outer positioning member 3202 and the third outer positioning member 3203. On the other hand, a pair of insertion members 130 is provided in the gap S1 between the first outer positioning member 3201 and the second outer positioning member 3202 and in the gap S2 between the first outer positioning member 3201 and the third outer positioning member 3203. And the leg portion 32 of the lead wire support member 30 is located.

  The gaps S1 and S2 in which the pair of insertion members 130 and the leg portions 32 coexist are a pair of insertion members even when the so-called bowl-shaped regions of the pair of insertion members 130 are closed or opened. It is large enough so that 130 and the leg part 32 do not contact. Thereby, there is no hindrance to the operation of the leader line positioning device 100 in the process until the attachment of the leader line support member 30 to the stator 10 is completed.

FIG. 30 is a plan view showing a state after insertion of the third inner positioning member of the second modification of the leader line positioning device used in the method for manufacturing a motor according to the embodiment of the present invention. FIG. 31 is a plan view showing a leader line positioning state of a second modification of the leader line positioning device used in the method for manufacturing a motor according to the embodiment of the present invention. Since the basic configuration of this embodiment is the same as that of the leader line positioning device 100 described above, the same reference numerals or the same names are assigned to the same components as those of the leader line positioning device 100. The description may be omitted.

  The leader line positioning device 400 of the second modification has an inner positioning member 410 and an outer positioning member 420 as shown in FIG.

  Four inner positioning members 410 (4101, 4102, 4103, 4104) are provided. In addition, the inner positioning member 410 is disposed on the radially outer side of the stator 10 in a stage before positioning of the lead wire 21. 29, 30 and 31, the first inner positioning member 4101 and the second inner positioning member 4102 are drawn in a state where they are already in contact with the leader line 21 from the central axis CL side.

  The first inner positioning member 4101 is provided on the first insertion member 4301. The first insertion member 4301 has a rod-like shape extending substantially along the radial direction of the stator 10, and has a configuration in which the bent portion 4311 is bent into an obtuse V-shape. The first inner positioning member 4101 is disposed at the distal end portion on the radially inner side of the stator 10 with respect to the bent portion 4311 of the first insertion member 4301. The first inner positioning member 4101 has four recesses 411. The first insertion member 4301 can move in a direction approaching and separating from the leader line 21.

The second inner positioning member 4102 has two recesses 411. The second insertion member 4302 can move in the direction of approaching and separating from the leader line 21.

  In the arrangement step of the inner positioning member 410, the first inner positioning member 4101 and the second inner positioning member 4102 are respectively provided with a gap provided between the adjacent lead wires 21 between the first insertion member 4301 and the second insertion member 4302. It is inserted from the outside in the radial direction of the stator 10 to the center axis CL side of the lead wire 21 through G1. The gap G1 through which the first insertion member 4301 and the second insertion member 4302 pass is wider in the direction intersecting the axial direction than other gaps through which the first insertion member 4301 and the second insertion member 4302 do not pass.

  The first insertion member 4301 and the second insertion member 4302 are bent portions 4311 and 4312 after the first inner positioning member 4101 or the second inner positioning member 4102 is inserted radially inward of the stator 10 with respect to the gap G, respectively. It is rotated around the axis. As a result, the first inner positioning member 4101 and the second inner positioning member 4102 each move radially outward with respect to the center axis CL, and come into contact with the leader line 21 from the center axis CL side of the leader line 21. . The first inner positioning member 4101 and the second inner positioning member 4102 include a leader line 21 adjacent to the gap G, and are connected to a plurality of leader lines 21 opposite to each other with the gap G therebetween. It contacts from the central axis CL side.

  The third inner positioning member 4103 is provided on the third insertion member 4303. The fourth inner positioning member 4104 is provided on the fourth insertion member 4304. Both the third insertion member 4303 and the fourth insertion member 4304 are supported by the support member 440.

  The support member 440 has a rod shape extending along the substantially radial direction of the stator 10. The support member 440 includes a support shaft 441 and a long hole portion 442. The support shaft 441 extends along the axial direction of the stator 10 and supports the third insertion member 4303 so as to be rotatable around the axis. The elongated hole portion 442 extends along the direction in which the support member 440 extends and is movable along the extending direction to support the fourth insertion member 4304. The support member 440 can move in a direction approaching and separating from the leader line 21.

  The third insertion member 4303 has a bar shape extending along the substantially radial direction of the stator 10, and has a configuration in which the bent portion 4313 is bent into an obtuse V shape. The third insertion member 4303 is supported by the support member 440 such that the bent portion 4313 is rotatable via the support shaft 441. The third inner positioning member 4103 is disposed at the distal end portion on the radially inner side of the stator 10 with respect to the bent portion 4313 of the third insertion member 4303. The third inner positioning member 4103 has two recesses 411.

  The fourth insertion member 4304 is a rod shape that extends along the substantially radial direction of the stator 10 and has a configuration that extends linearly. The fourth insertion member 4304 has a pin 4314. The pin 4314 is provided at the radially inner tip of the stator 10 and protrudes toward the support member 440. The fourth insertion member 4304 is supported by the support member 440 so that the pin 4314 is inserted into the elongated hole portion 442 and is movable along the extending direction of the elongated hole portion 442. The fourth inner positioning member 4104 is disposed over the entire area of the fourth insertion member 4304 in the longitudinal direction. The fourth inner positioning member 4104 has four recesses 411.

  A connecting shaft 432 is provided at the most distal end of the third insertion member 4303 in the radial direction of the stator 10 and at the most distal end of the fourth insertion member 4304 in the radial direction of the stator 10. The connection shaft 432 extends along the axial direction of the stator 10 and is rotatable about the axis thereof to connect the third insertion member 4303 and the fourth insertion member 4304.

  When the region on the radially outer side of the stator 10 with respect to the support shaft 441 of the third insertion member 4303 is rotated in the direction away from the support member 440 (counterclockwise in FIG. 29), the third inner positioning is performed. The member 4103 and the fourth inner positioning member 4104 approach the support member 440. When the third inner positioning member 4103 and the fourth inner positioning member 4104 are adjacent to the support member 440, the third inner positioning member 4103, the fourth inner positioning member 4104, and the support member 440 are linear and along the radial direction of the stator 10. Extend.

  In the arrangement step of the inner positioning member 410, the third inner positioning member 4103 and the fourth inner positioning member 4104 are respectively replaced with the third inner positioning member 4103 and the fourth inner positioning member 4104 as the support member 440 as shown in FIG. In an adjacent state, the lead wire 21 is inserted from the radially outer side of the stator 10 to the center axis CL side of the lead wire 21 through a gap G2 provided between the lead wires 21 adjacent to each other. At this time, the distal end portions in the insertion direction of the fourth inner positioning member 4104 and the support member 440 are directed radially outward of the stator 10 from the gap G3 provided on the opposite side of the gap G2 with respect to the central axis CL. Protruding. The gaps G2 and G3 are wider in the direction intersecting the axial direction than the other gaps through which the insertion member 430 and the support member 440 do not pass, except for the gap G1. The gap G1 is wider than the gaps G2 and G3.

  Since the third inner positioning member 4103 and the fourth inner positioning member 4104 are adjacent to the support member 440 and can be arranged linearly in a direction intersecting the axial direction of the stator 10, the inner positioning member 410 can be downsized. Can be achieved. Therefore, it is possible to pass the inner positioning member 410 between adjacent leader lines 21 that are relatively narrow.

  Subsequently, as shown in FIG. 31, the region of the third insertion member 4303 on the radially outer side of the stator 10 with respect to the support shaft 441 is directed in the direction approaching the support member 440 (clockwise in FIG. 31). When rotated, the third inner positioning member 4103 and the fourth inner positioning member 4104 move radially outward with respect to the central axis CL. The distal end portion on the gap G3 side of the fourth inner positioning member 4104 moves linearly along the substantially radial direction via the pin 4314 and the elongated hole portion 442. The third inner positioning member 4103 and the fourth inner positioning member 4104 are bent in a substantially L shape around the axis of the connecting shaft 432. Thereby, the 3rd inner side positioning member 4103 and the 4th inner side positioning member 4104 each contact the leader line 21 from the central-axis CL side of the leader line 21. FIG.

  According to this configuration, the third inner positioning member 4103 is rotated by rotating the region of the third insertion member 4303 radially outward of the stator 10 with respect to the support shaft 441 in a direction in which the third insertion member 4303 approaches the support member 440. And the 4th inner side positioning member 4104 moves to the direction approaching the central axis CL side of the leader line 21. FIG. On the other hand, the third inner positioning member 4103 and the fourth inner member 4303 are rotated by rotating a region radially outside the stator 10 with respect to the support shaft 441 toward the support member 440. The inner positioning member 4104 moves in a direction away from the center axis CL side of the leader line 21. That is, the third inner positioning member 4103 and the fourth inner positioning member are formed by causing the region on the radially outer side of the stator 10 with respect to the support shaft 441 of the third insertion member 4303 to approach and separate from the support member 440. 4104 can be moved easily.

  Five outer positioning members 420 (4201, 4202, 4203, 4204, 4205) are provided. The five outer positioning members 420 are arranged side by side at a predetermined interval in the circumferential direction. The outer positioning member 420 is disposed on the outer side in the radial direction of the stator 10 before the lead wire 21 is positioned. 29, 30 and 31, the outer positioning member 420 has already drawn the state in which it has contacted the leader line 21 from the opposite side to the central axis CL.

  Each of the first outer positioning member 4201, the second outer positioning member 4202, the third outer positioning member 4203, and the fourth outer positioning member 4204 has two recesses 421 individually. The fifth outer positioning member 4205 has four recesses 421. The first outer positioning member 4201 and the second outer positioning member 4202 are opposed to the first inner positioning member 4101 with the leader line 21 interposed therebetween. The third outer positioning member 4203 faces the second inner positioning member 4102 with the leader line 21 interposed therebetween. The fourth outer positioning member 4204 faces the third inner positioning member 4103 with the leader line 21 interposed therebetween. The fifth outer positioning member 4205 faces the fourth inner positioning member 4104 with the leader line 21 interposed therebetween.

  Each of the five outer positioning members 420 has a substantially rectangular shape extending in the radial direction of the stator 10 in plan view. Further, each of the five outer positioning members 420 can move in a direction in which a substantially central portion in the circumferential direction of the stator 10 approaches and separates from the lead wire 21 along a substantially radial direction of the stator 10. is there. Thereby, the recessed part 421 can contact the leader line 21 from the opposite side to the center axis CL of the leader line 21.

  The third outer positioning member 4203 and the fourth outer positioning member 4204 each have a notch 422. The notch 422 is provided between the two recesses 421 in the circumferential direction. The notch 422 is provided in a region of the third outer positioning member 4203 and the fourth outer positioning member 4204 facing the central axis CL, and is a direction (radial direction) away from the central axis CL along the radial direction of the stator 10. It dents towards the outside. The leg portion 32 of the lead wire support member 30 is located in the notch portion 422.

  As shown in FIG. 31, with respect to the five outer positioning members 420 in the positioning state with respect to the lead wire 21, five gaps S (S 1, S1, S) between the adjacent outer positioning members 420 above the outer edge portion of the stator 10. S2, S3, S4, S5) occur.

  Among the five gaps S, the gap S1 between the first outer positioning member 4201 and the second outer positioning member 4202 and the gap S4 between the fourth outer positioning member 4204 and the fifth outer positioning member 4205 are included. The leg portion 32 of the lead wire support member 30 is located. On the other hand, the support member 440 passes through the gap S3 between the third outer positioning member 4203 and the fourth outer positioning member 4204 and the gap S5 between the fifth outer positioning member 4205 and the first outer positioning member 4201. . Further, the first insertion member 4301 and the second insertion member 4302 pass through the gap S2 between the second outer positioning member 4202 and the third outer positioning member 4203, and the leg portions 32 of the lead wire support member 30 are two. It is located.

  The gap S2 in which the first insertion member 4301 and the second insertion member 4302 and the two leg portions 32 coexist is that the first insertion member 4301 and the second insertion member 4302 are on the center axis CL side of the lead wire 21. When inserted and removed, the first inner positioning member 4101 and the second inner positioning member 4102 are sufficiently large so as not to contact the leg portion 32. Thereby, there is no hindrance to the operation of the leader line positioning device 400 in the process until the attachment of the leader line support member 30 to the stator 10 is completed.

  The leader line positioning device 400 is suitable as a gap between adjacent leader lines 21 in the stator 10 when the two gaps are not point-symmetric with respect to the central axis CL.

<4. Other>
The leader line positioning device 100 brings the inner positioning member 110 and the outer positioning member 120 into contact with the leader line 21 from both the radially inner side and the radially outer side of the leader line 21. Thereby, the leader line positioning device 100 can position the leader line 21 at a predetermined position regardless of whether the leader line 21 is displaced radially inward or radially outward.

  Further, in the inner positioning member 110 and the outer positioning member 120, the recesses 111, 111 </ b> A, 111 </ b> B, 121, 121 </ b> A, 121 </ b> B are opened toward the lead line 21. Thereby, even if the leader line 21 is displaced in the circumferential direction, the leader line positioning device 100 positions the leader line 21 at a predetermined position within a range that can be accommodated in the recesses 111, 111A, 111B, 121, 121A, 121B. can do.

  Before and after the leader line support member 30 is attached to the stator 10, the leader line positioning device 100 is a member for positioning from the inside of the plurality of leader lines 21 arranged in an annular shape and extending in the axial direction. This is effective for a request that enables insertion and removal from the center axis CL side.

  For example, if the leader line support member is inserted from one side of the axial direction of the center hole of the stator and is made to face a plurality of leader lines on the other side, the movement direction of the leader line support member is changed between the axial direction and the diameter. There are two directions.

  On the other hand, the leader line positioning device 100 of the present embodiment only moves in the direction in which the inner positioning member 110 intersects the axial direction, and the side where the leader line 21 is positioned with respect to the stator 10 (axial direction) This is a configuration arranged on the upper side. Thereby, the leader line positioning device 100 can be simply and miniaturized.

  Further, in the leader line positioning device 100 shown in FIG. 12, two pairs of insertion members 130 are arranged to face each other with the central axis CL interposed therebetween. The inner positioning member 110 of each insertion member 130 contacts the leader line 21 arranged in a range of an angle of 90 degrees with respect to the central axis CL among the plurality of leader lines 21 arranged along the circumference. According to this configuration, since one inner positioning member 110 can be opposed to the plurality of lead lines 21 positioned in the range of 90 degrees, the inner positioning member 110 can be configured simply. It is.

  For example, suppose that the leader line positioning device has a folding configuration in which one inner positioning member can be changed into an annular state and a linear state, and one inner positioning member can be changed into a semicircular state and a linear state. It is also possible to adopt a configuration in which two foldable ones are used.

  Furthermore, the structure which arrange | positions six inner positioning members every 60 degree | times can also be performed.

  On the other hand, the leader line positioning device 100 of this embodiment can make one leader line positioning member 110 into an appropriate length. Furthermore, since the leader line positioning device 100 has two gaps G between the adjacent leader lines 21 for inserting the pair of insertion members 130, the gap G for inserting the pair of insertion members 130 is provided. It is easy to secure.

  Further, as shown in FIG. 5, two gaps G through which each of the two pairs of insertion members 130 individually pass among the gaps between the adjacent leader lines 21 are not allowed to pass through the pair of insertion members 130. The width in the direction intersecting the axial direction is wider than the gap. That is, the two gaps G correspond to the top two places in the descending order of the width in the direction intersecting the axial direction among the gaps between all the adjacent leader lines 21. By selecting two gaps G as gaps for inserting and removing the pair of insertion members 130, the pair of insertion members 130 can be easily inserted and removed.

  The two gaps G shown in FIG. 5 correspond to the gaps between the second straight portions 21 c of the adjacent leader lines 21. If the leader line 21 does not have the first straight line portion 21b and is configured only by the second straight line portion 21c, the gap where the insertion member is inserted and removed is the same between the adjacent second straight line portions 21c. It corresponds to the gap between.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

  The present invention can be used, for example, in a method for attaching a support member to a lead wire of a motor and a motor.
