Hairpin alignment device for hairpin winding motor

A hairpin alignment device for a hairpin winding motor for pre-aligning a plurality of hairpins inserted into a hairpin winding motor as at least one layer to a slot of a dummy core, the device comprising:

• a rotation unit having a center, the dummy core being mounted in the center, wherein the rotation unit rotates the dummy core by a first predetermined angle in correspondence with a number of slots;
• an alignment unit positioned on an upper surface of the rotation unit, and including a plurality of push bars positioned along a circumference of an upper end of the dummy core, wherein the plurality of push bars are configured to reciprocate in a radial direction with respect to the plurality of hairpins;
• a guide unit positioned on a side of the rotation unit, the guide unit selectively operating with one of the plurality of hairpins overlapped in each layer when pre-aligning the hairpin to the slot, and moving the overlapping hairpin outward in a radial direction to secure an inserting space of the hairpin;
• and
• a handling gripper adjacent to the rotation unit and inserting the hairpin into the slot of the dummy core;
• wherein the rotation unit includes:
• a rotation jig configured to clamp at least one mount block mounted along the lateral circumference of the dummy core, and configured to rotate the dummy core by a first predetermined angle;
• and
• a lower plate positioned under the lower part of the dummy core, and configured to push the hairpin pre-aligned to the slot upward from the dummy core.
