Apparatus for molding hairpin

1. 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.

2. The apparatus of claim 1 , wherein:

the at least one clamper comprises a pair of clampers, each of which comprises a first end mounted on the connection bracket and a second end on which a fitting end protrudes; and

the pair of clampers is configured to reciprocate to become closer and farther with reference to a central portion of the connection bracket.

3. The apparatus of claim 2 , wherein the fitting end is slidably inserted into a mounting slot formed in the molding jig.

4. The apparatus of claim 2 , wherein the mold unit is detachably coupled with the connection bracket at a position between the pair of clampers by a fixing chuck.

5. The apparatus of claim 4 , wherein the fixing chuck comprises:

a fixing block mounted on the connection bracket; and

a plurality of fixing pins disposed along an exterior circumference of the fixing block, and configured to be inserted into the fixing block and to protrude from the fixing block.

6. The apparatus of claim 4 , wherein the mold unit comprises:

a fixing plate coupled to the connection bracket through the fixing chuck;

a support bar fixed to the fixing plate; and

at least one molding jig coupled with the at least one clamper and configured to be driven by the at least one clamper to move along the support bar to mold the head portion of the hairpin.

7. The apparatus of claim 6 , wherein:

the at least one molding jig comprises a first jig and a second jig coupled with the at least one clamper; and

the first jig and the second jig are configured to move to be closer or farther along a guide bar.

8. 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.

9. The apparatus of claim 8 , wherein the pair of clampers is configured to reciprocate to become closer and farther with reference to a central portion of the connection bracket.

10. The apparatus of claim 8 , wherein:

each molding jig of the pair of molding jigs comprises a mounting slot; and

the fitting ends of the pair of clampers are slidably inserted into the mounting slots.

11. The apparatus of claim 8 , wherein the fixing chuck comprises:

a fixing block mounted on the connection bracket; and

a plurality of fixing pins disposed along an exterior circumference of the fixing block, and configured to be inserted into the fixing block and to protrude from the fixing block.

12. The apparatus of claim 8 , wherein the mold unit comprises:

a fixing plate coupled to the connection bracket through the fixing chuck; and

a support bar fixed to the fixing plate,

wherein the pair of molding jigs is configured to be driven by the pair of clampers to move along the support bar to mold the head portion of the hairpin.
