Provided are an alignment method and an alignment device by which, immediately before aligning, the leg parts of adjacent conductors do not interfere with each other. The alignment method, in which by providing a plurality of coil elements () in an annular shape and moving the plurality of coil elements () in a direction in which the diameter of the annular shape is reduced, the plurality of coil elements () are aligned in a state where turn sections () provided at substantially apex portions are alternately overlapped, wherein the plurality of coil elements () are aligned by moving each of the plurality of coil elements () toward an annularly shaped center, and while doing so, rotating the plurality of coil elements about a rotation axis () that is parallel to the central axis (C) of the annular shape.

Motor component alignment method

A conductive-wire position inspecting device includes: a reference body disposed in a radial direction of a stator core; an imaging device configured to image a conductive wire and the reference body; and a calculating device configured to find a relative position and a relative angle of the conductive wire with respect to the reference body, based on an obtained image. In addition, the conductive-wire position inspecting device includes a determining device configured to determine whether or not the found relative position and relative angle are within respective permissible ranges, and if they are within the permissible ranges, determine the position of the conductive wire to be acceptable.

Conductive-wire position inspecting method and device

Provided are an insertion method and an insertion apparatus for efficiently and reliably inserting a plurality of coil elements aligned in a ring shape into respective slots of a stator core. In an insertion method of inserting, the insertion method includes a coil element alignment process Sof forming an assembly bodyby assembling the plurality of coil elementsin a ring shape in the state where the turn portionsalternately overlap each other, a supporting process Sof supporting the assembly bodyby using the turn portions, and an insertion process Sof allowing the assembly bodyand the stator coreto be close to each other and inserting the leg portionsof the coil elementsof the assembly bodyinto the slots

Insertion apparatus which inserts U-shaped conductors

A first leading end plate and a first rear end plate are provided at an upper part of a rotary table. When a conductor piece contacts the first leading end plate, a first contact detection sensor detects a contact of the conductor piece, and transmits a contact detection signal to a storage control unit. Upon receiving the contact detection signal, the storage control unit drives an air supply device for a predetermined period to spray air toward the conductor piece from a first air nozzle. The air spray brings the conductor piece into a tilted state with the rear end thereof moved downward. Even when the conductor piece contacts the first leading end plate and rebounds, the rear end thereof contacts an inner wall surface of the first rear end plate, thereby preventing the rear end of the conductor piece from getting over the first rear end plate.

Workpiece storage method

The transport device includes a backflow prevention mechanism that prevents backflow in which workpieces are moved in the direction opposite to the predetermined direction, the backflow prevention mechanism has two backflow prevention valvesattached to an end portion of a transport rail, and each of the backflow prevention valveshas an inductive plateinclined with respect to the predetermined direction from the center of the transport rail to the side along the predetermined direction, and a coupling platecombining a center side end portion of the inductive platepositioned close to the center of the transport rail and a side surface of the transport rail.

Transport device

A coil segment manufacturing apparatus includes a conducting wire material feeder which repeatedly feeds a conducting wire material while changing the feeding amount and interposing a processing time, a coating remover which removes an insulation coating of the conducting wire material at a removal position each time the processing time is reached, and a conducting wire material cutter which cuts the conducting wire material each time the processing time is reached.

Insertion method of U-shaped conductors

A conductive wire piece supply method includes the steps of: obtaining a conductive wire piece set using a first slot which receives conductive wire pieces, having been sent, with the conductive wire pieces vertically superposed on each other; carrying the conductive wire piece set from the first slot portion to the second slot portion; and rotating the second slot portion.

Conductive wire piece supply method and conductive wire piece supply device

An arrangement apparatus and an arrangement method of allowing gripping devices to grip electrical conductors by using inexpensive, simple, and small-sized configurations. A stator manufacturing apparatus for arranging coil elements in a ring shape includes: a plurality of gripping devices that are arranged in a ring shape and grip coil elements; robot arms that supply the coil elements to the gripping devices; and a turntable that integrally rotates the plurality of gripping devices. According to this, the gripping devices are rotated by the turntable is aligned in a ring shape, and thus, the coil elements are supplied to the arrangement points by the robot arms and the plurality of coil elements can be aligned in a ring shape while gripped by the gripping devices.
