A stator manufacturing apparatus includes an insertion tool that is insertable into a stator core and being configured to dispose a pair of side parts of a stator coil in two holding grooves. A pressing tool has plate-like pushers arranged to correspond to the positions of the holding grooves. The pressing tool pushes out the side parts of the stator coils and inserts the side parts into the corresponding slots. A pair of shaping tools face coil end parts of the stator coils. A plurality of slits through which the pushers are insertable are provided in a principal surface of each shaping tool. A shaping tool moving unit shapes the coil end parts by pressing the pair of shaping tools in an axial direction with the pushers inserted in each of the corresponding holding grooves.

Stator manufacturing apparatus and stator manufacturing method

An apparatus for manufacturing an electronic component includes a grip unit configured to grip an electronic member having a plurality of projections arranged thereon, a connected coil assembly forming unit configured to form a connected coil assembly in which a plurality of single coils are connected to one another, and a coil mounting unit configured to sequentially mount the plurality of single coils of the connected coil assembly on the plurality of projections.

Apparatus and method for manufacturing electronic component

A coil shaping device includes a plurality of rollers having an outer circumference formed with a concave groove having an arc-shaped cross section, a roller moving mechanism making the rollers move between a gripping position, at the gripping position the plurality of rollers grips the coil from surroundings of the coil, and a separating position, at the separating position the plurality of rollers is separated from the coil, and a rolling movement mechanism making the plurality of rollers positioned in the gripping position move, by the plurality of rollers being rolled in a longitudinal direction of the coil.

Coil shaping device and coil shaping method

A winding apparatus includes a nozzle that is adapted to rotate about a core along a locus that is inclined relative to a center line of the core, wire material winding members that are adapted to guide a wire material wound via the nozzle to the core, and a core rotating mechanism that is adapted to rotate the core relative to the wire material winding members. The wire material winding members are disposed on either side of the core so as to sandwich a plane that includes both a rotary center of the nozzle and the center line of the core, whereby the wire material winding members extend in a tangential direction to the core such that respective tip ends thereof are oriented in a rotation direction of the core. The wire material is successively wound diagonally around the core.

Winding apparatus and winding method

The coil winding device includes a nozzle configured to feed a wire to wind the wire around the winding core to form a coil, a plurality of hook rods disposed in predetermined intervals around an end part of the winding core, the wire drawn out from an edge of the coil being configured to be hooked to each of the plurality of hook rods during a forming process of the coil, a winding core rotating mechanism configured to rotate the winding core together with the plurality of hook rods, a hook rod rotating mechanism configured to rotate the plurality of the hook rods, and a wire drawing-out mechanism configured to draw out the wire from the edge of the coil and hook the wire on the hook rods during the forming process of the coil.

Coil winding device and winding method thereof

The multiple winding apparatus for coil includes a winding core, a spindle shaft on a tip end of which the winding core is removably mounted and which rotates together with the winding core, a wire rod feeding flyer which feeds a wire rod while rotating around the winding core mounted on the spindle shaft, a winding core removal mechanism which removes the winding core from the spindle shaft by moving the winding core in an axial direction, a supporting member which faces the spindle shaft and supports a plurality of the winding cores removed by the winding core removal mechanism at desired intervals in the axial direction, and a support member moving mechanism which moves the supporting member supporting the winding cores from a position facing the spindle shaft in a direction away from the spindle shaft.

Multiple winding apparatus and multiple winding method for coil

The wire winding apparatus includes: a wire feeding member provided to a supporting member so as to be operable, for feeding a wire; a lock mechanism capable of inhibiting an operation of the wire feeding member; a winding mechanism for rotating a core about an axis thereof to wind the wire fed from the wire feeding member around the outer circumference of the core; a feed mechanism for moving the supporting member in an axial direction of the core in synchronization with the winding performed by the winding mechanism; a proximity sensor for detecting a movement amount of the wire feeding member with respect to the supporting member; and a control section for controlling an operation of the feed mechanism to adjust a movement amount of the supporting member moved by the feed mechanism based on a detection output from the proximity sensor.
