Abstract
An apparatus for molding a hairpin inserted into a stator core includes a clamping unit including a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket and configured to be reciprocally driven in opposite directions in a straight line, and a mold unit detachably coupled with the at least one clamper and configured to press mold a head portion of the hairpin by a molding jig configured to be driven by the at least one clamper.
Claims18
An apparatus for molding a hairpin inserted into a stator core, the apparatus comprising:
- a clamping unit including a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket and configured to be reciprocally driven in opposite directions in a straight line;
- and
- a mold unit detachably coupled with the at least one clamper and configured to press mold a head portion of the hairpin by a molding jig configured to be driven by the at least one clamper.
A method of inserting a hairpin into a stator core, the comprising:
- unwinding a coil spiral-wound on an uncoiler;
- forming a decoated portion by decoating a predetermined portion on the coil;
- bending the coil in multiple stages to two-dimensionally form a leg portion and a head portion;
- cutting the coil formed with the leg portion and the head portion by a predetermined length;
- and
- moving the hairpin to be inserted into the stator core while three-dimensionally forming the head portion.
An apparatus for molding a hairpin inserted into a stator core, the apparatus comprising:
- a clamping unit including a connection bracket mounted on a front end of a robot arm and a pair of clampers mounted on the connection bracket and configured to be reciprocally driven in opposite directions in a straight line, wherein each clamper of the pair of clampers comprises a first end mounted on the connection bracket and a second end on which a fitting end protrudes;
- and
- a mold unit detachably coupled with the connection bracket at a position between the pair of clampers by a fixing chuck, detachably coupled with the pair of clampers, and configured to press mold a head portion of the hairpin by a pair of molding jigs configured to be driven by the pair of clampers.
