Embodiment Construction
[0074] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, although the embodiments described below describe the case where a flat wire having a quadrangular cross section is used as the wire rod, even if it is a wire rod formed of a single wire or a stranded wire having a circular, square, polygonal or other arbitrary cross-sectional shape, The present invention can also be applied.
[0075] like figure 1 As shown, the manufacturing apparatus 100 of the rotating electric machine according to the first embodiment of the present invention includes: a coil segment forming device 1; The circumferentially arranged ring-shaped slots are assembled in a corresponding manner to create assembled coils. The coil segment forming device 1 includes: a wire supply unit 3; and a primary bending unit 4 that bends a linear wire of a predetermined length supplied from the wire supply unit 3 into a predetermined shape in the same pla...

Provided is a coil assembling device, a coil assembling method, and a rotating electric machine manufacturing device capable of quickly and efficiently assembling a coil from a plurality of coil segments and capable of easily and quickly assembling a coil comprising a multilayer coil segment. The coil assembling device is provided with: a conveying means for sequentially conveying a plurality of coil segments each comprising a pair of slot insertion portions extending substantially in parallel with each other and a jumper portion connecting the pair of slot insertion portions; a segment arranging body having a plurality of segment holding portions arranged in a circular ring shape along the circumferential direction and capable of rotating about the central axis, the segment holding portions enabling the respective plurality of coil segments conveyed by the conveying means to be inserted thereinto from the outside in a radial direction; and a guide means is configured so that: one of the pair of slot insertion portions of each of the plurality of coil segments is guided to and inserted into one of the plurality of segment holding portions every time the segment arranging body rotates by a first predetermined angle; and the other of the pair of slot insertion portions is guided to and inserted into another one of the plurality of segment holding portions when the segment arranging body rotates by a second predetermined angle from the insertion of the one of the slot insertion portions.
Description
technical field [0001] The present invention relates to a coil assembling device, a coil assembling method, and a manufacturing device for a rotating electric machine used for forming coils of a stator or a rotor in a rotating electric machine such as a motor or a generator. Background technique [0002] As a coil of a stator or a rotor in a rotating electric machine, a so-called segmented coil is known, which is inserted into a plurality of slots arranged along the circumferential direction of the iron core of the stator or rotor, and the wire is processed A coil is formed by forming a plurality of coil segments (return bending members) obtained in a U-shape, and joining free end sides of these coil segments to each other by welding or the like. The segmented coil does not require a winding process, so it is easier to increase the slot occupation ratio compared with conventional winding coils, and a small and high-output rotating electrical machine can be obtained.
