Patent ID: 7663073

Claim:
An optical processing apparatus comprising: an emitter for emitting light; a first light path for directing the light to a position to be processed on a workpiece; a processing head including an optical system provided in the first light path, for shaping the light, a second light path having a portion shared with the first light path, the second light path directing light reflected from the workpiece, and an optical receiver for receiving the reflected light from the second light path; an actuator for changing a positional relationship between the optical system and the workpiece; a feeder for supplying a solder to the workpiece; a first shifter for moving the processing head in a first direction in parallel to an optical axis of the light emitted from the emitter; a second shifter for positioning the feeder in the first direction away from the processing head when the processing head is moved away from the workpiece by the first shifter; and a third shifter for moving the feeder against the processing head in a second direction perpendicular to the first direction while the processing head is moved by the first shifter, wherein the optical system is configured to radiate, onto the workpiece, (a) focused light, and (b) light having a center portion and a circumference portion located outside of the center portion, the circumference portion having an energy density higher than an energy density of the center portion, when the optical system radiates the focused light onto the workpiece, the feeder supplies the solder to a portion of the workpiece onto which the focused light is radiated, and when the optical system radiates the light having the center portion and the circumference portion, the feeder supplies the solder to a portion of the workpiece onto which the circumference portion of the light is radiated.
