[0167] The elevator mechanism (120) may include a driving source such as a motor or cylinder, and at least one power transmission member connected to a clamp case (4) or supporting a stator (2).

[0168] Hereinafter, the lifting mechanism (120) is described as lifting the stator (2), but is not limited to lifting the stator (2), and can also lift the clamp case (4).

[0169] The hairpin alignment device may include a controller (130).

[0170] The controller (130) can control the overall operation of the hairpin alignment device.

[0171] The controller (130) can control the driving source of the cam rotor.

[0172] The controller (130) can control the driving source of the elevator mechanism (120).

[0173] The above description is merely an example of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention.

[0174] Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of ​​the present invention but to explain it, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.

[0175] The scope of protection of the present invention should be interpreted by the claims below, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
