Abstract
Official abstract text for this publication.
A method can be used for molding a hairpin inserted into a stator core using a clamping unit that includes a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket. The method includes reciprocally driving the clamping unit in opposite directions in a straight line, and press molding a head portion of the hairpin using a molding jig driven by the at least one clamper.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for molding a hairpin inserted into a stator core using a clamping unit that includes a connection bracket mounted on a front end of a robot arm and at least one clamper mounted on the connection bracket, the method comprising: reciprocally driving the clamping unit in opposite directions in a straight line; and press molding a head portion of the hairpin using a molding jig driven by the at least one clamper. 2 . The method 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 wherein reciprocally driving the clamping unit comprises moving the pair of clampers to become closer and farther with reference to a central portion of the connection bracket. 3 . The method of claim 2 , further comprising slidably inserting the fitting end into a mounting slot formed in the molding jig. 4 . The method of claim 2 , wherein the press molding uses a mold unit that is detachably coupled with the connection bracket at a position between the pair of clampers by a fixing chuck, 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, the fixing pins being inserted into the fixing block and protruding from the fixing block. 5 . The method of claim 2 , wherein the press molding uses a mold unit that is detachably coupled with the connection bracket at a position between the pair of clampers by a fixing chuck, 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 a pair of molding jigs coupled with the pair of clampers; wherein the press molding comprises driving the pair of clampers to move along the support bar to mold the head portion of the hairpin.
