Definitions
- the tool When inserting the at least one tooth, the tool is tilted around an axis perpendicular to the insertion direction of the at least one tooth and the radial direction, so that the tip of the at least one tooth is positioned on the segment coil leg portion. It is made non-contact with the insulating coating of the terminal of As a result, it is possible to prevent the insulating coating on the ends of the segment coil legs from being damaged.
- the stator core 14 corresponds to the "core" in the present disclosure.
- the stator core 14 is formed in a cylindrical shape by stacking a large number of electromagnetic steel sheets.
- a large number of slots 16 are formed in the inner peripheral portion of the stator core 14 .
- the multiple slots 16 are open on both axial sides and radially inside of the stator core 14 .
- arrows Y1, Y2, and X indicate one axial direction, the other axial direction, and the radial direction of the stator core 14, respectively.
- the axial direction of the stator core 14 may simply be referred to as the "axial direction”
- the radial direction of the stator core 14 may simply be referred to as the "radial direction”
- the circumferential direction of the stator core 14 may simply be referred to as the "circumferential direction”.
- the axial length of the leg portions 42A, 42B of the segment coil 40 increases from the inner layer 46A to the outer layer 46C in the three layers 46A, 46B, 46C. It is designed to be progressively longer. 3 and 4, in each slot 16, one leg portion 42A of one segment coil 40 is connected to the other leg portion 42A of the other segment coil 40 for each layer 46A, 46B, 46C. It overlaps radially outward with respect to the side leg portion 42B.
- the step of pushing a large number of segment coils 40 is performed using the first jig 50 and the second jig 60 shown in FIG. Due to this pushing process, a large number of segment coils 40 are pushed to the positions set with respect to the stator core 14 .
- the terminals of the legs 42A, 42B protrude from the end surface 14A on the other axial side of the stator core 14 toward the outer layer 46C from the inner layer 46A of the plurality of layers 46A, 46B, 46C.
- the amount increases step by step.
- the leg portions 42A and 42B of the segment coil 40 may be simply referred to as "leg portion 42".
- the interlayer expansion device 70 is used to expand radial gaps between the ends of the leg portions 42 of the layers 46A, 46B, and 46C (hereinafter simply referred to as "terminal gaps").
- This gap widening is performed sequentially for each slot 16 as an example.
- This widening of the gap causes the multiple (here six) legs 42 inserted into the same slot 16 to be spaced apart from each other in pairs 42A, 42B of each layer 46A, 46B, 46C.
- reference numeral 48 denotes insulating paper (not shown in FIGS. 1, 3 and 4) for insulating the leg portion 42 of the segment coil 40 from the stator core 14. As shown in FIG.
- the tool 74 is an end effector attached to the tip of the robot manipulator 72 and made of metal, for example.
- This tool 74 has comb teeth 76 formed in the shape of comb teeth.
- the comb tines 76 have a plurality of (here, three) teeth 76 A, 76 B, 76 C spaced apart in the axial direction of the sixth axis of the robot manipulator 72 .
- the three teeth 76A, 76B, and 76C are formed in a plate shape with the thickness direction being the axial direction of the sixth shaft and the longitudinal direction being the radial direction of the sixth shaft.
- the pusher 84 is made of resin, for example, in the shape of a block, and is arranged radially outside the stator core 14 with respect to the tip of the protruding portion from the end surface 14A of the stator core 14 at the end of the leg portion 42B of the outer layer 46C. be done.
- the pusher 84 is radially moved by an actuator (not shown) (see arrow C in FIG. 5). This pusher 84 can push the ends of the leg portions 42 of the outer layer 46C radially inward.
- the tool 74 is axially and radially moved by the robot manipulator 72 (see arrows D1, E1 and D2 in FIG. 7).
- the tips of the comb teeth 76 of the tool 74 are inserted between the ends of the legs 42 of each layer 46A, 46B, 46C.
- the tips of teeth 76B of comb teeth 76 are inserted between layers 46A and 46B
- the tips of teeth 76C of comb teeth 76 are inserted between layers 46B and 46C.
- the tool 74 is moved in one axial direction (downward) by the robot manipulator 72 so that the teeth 76B, 76C of the comb teeth 76 are axially moved in the other axial direction between the ends of the legs 42 of the layers 46A, 46B, 46C. It is inserted toward one axial side (lower side) from the side (upper side). During this insertion, the tool 74 is tilted in the row direction (radial direction) of the comb teeth 76 and around an axis orthogonal to the insertion direction (here, around the fifth axis of the robot manipulator 72).
- the comb teeth 76 may be inserted between the ends of the legs 42 of the layers 46A, 46B, and 46C while tilting the tool 74 around the fifth axis of the robot manipulator 72. Further, the tool 74 may or may not be inclined with the comb teeth 76 fully inserted between the ends of the leg portions 42 of the layers 46A, 46B, and 46C.
- the tip of the comb tooth 76 is kept out of contact with the end of the leg 42 due to the inclination of the tool 74 as described above, so that the insulating coating on the end of the leg 42 is not damaged. Not only can this be prevented, but also an increase in the load on the robot manipulator 72 and an accidental displacement of the segment coil 40 can be avoided. Moreover, since it is possible to use the tool 74 with the pointed ends of the comb teeth 76, the insertion of the comb teeth 76 between the ends of the legs 42 of the layers 46A, 46B, and 46C is facilitated.
