SOLUTION: By arranging a nozzle 1020 at a position offset from a core supporting part 1010, a part of wiring 7 in which a delaminated part 7h is formed is arranged at a position close to a metal terminal 6. Then, a laser is irradiated to a position which is close to the metal terminal 6 and a part of the wiring 7 to form a half-delaminated part. The core supporting part 1010 is rotated at 180 degrees to locate a laser at the position offset from the core supporting part 1010. Then, the laser is irradiated to the position close to the metal terminal 6 of the wiring 7 to form the delaminated part 7h. The delaminated part 7h is arranged on the metal terminal 6 of a flange 4.

Abstract:
PROBLEM TO BE SOLVED: To provide a coil part joint device which assures welding of a coil and a metal terminal, and improves the reliability of joint, and to provide a jointing method thereof. SOLUTION: In this jointing device 1, a CCD camera 17 takes a surface image on a coil part 51, and an image processing device 15 processes the image to determine a laser irradiation position on the coil part 51. A main controller 7 activates each of motors 29, 31 and 35 to adjust the position of a laser head 47 so that welding laser beams can be irradiated at a determined laser irradiation position. A laser oscillator 3 is controlled by a main controller 7 to output welding laser beams with a predetermined power in a given period of time. At this time, the irradiation position is an asymmetric region 109E2, extending from a guard 107 in the welding part 109E of the coil part 51. Consequently, a fused ball formation position is constant for the metal terminal 109 and coil 103, resulting in assured joint. COPYRIGHT: (C)2007,JPO&INPIT
