Laser soldering method and apparatus
First Claim
1. A laser soldering method characterized in that:
- an image pickup camera is mounted on a soldering head for projecting a laser beam for soldering toward an object to be soldered in such a manner that an optical axis thereof coincides with that of said laser beam; and
the camera images the object to be soldered and displays the image on a monitor screen, wherein a projection spot positioned on an optical axis of the laser beam is displayed on the monitor screen, wherein, while the positional relationship between the object to be soldered and the projection spot is observed on the monitor screen, said soldering head and the object to be soldered are moved relative to each other to position said projection spot, and wherein the laser beam is projected from said soldering head to the object to be soldered, thus, performing soldering.

Abstract
An image pickup camera is mounted on a soldering head for projecting a laser beam in such a manner that its optical axis coincides with that of the laser beam. An image of the object to be soldered, which is taken by the camera, is displayed on a monitor screen, and a projection spot, which is positioned on an optical axis of the laser beam, is displayed on the screen. While the positional relationship between the object to be soldered and the projection spot is observed on the monitor screen, the soldering head and the object to be soldered are moved relative to each other and the projection spot is positioned. Subsequently, the laser beam is projected from the soldering head, thus, performing soldering.

10. A soldering head characterized by comprising:
-
a cylindrical casing having a projection aperture for projecting a laser beam toward an object to be soldered at an end thereof;
optical lenses disposed in said casing and a half mirror disposed at a position nearer to a base end of the casing than to the optical lenses in such a manner that the half mirror is disposed at an angle of 45 degrees to an optical axis of the optical lenses;
a camera mounted on the base end of said casing in such a manner that it can image the object to be soldered from the projection aperture via said half mirror and the optical lenses; and
a fiber connecting section formed at the side of said casing at a position corresponding to said half mirror in such a manner that an optical fiber from a laser mechanism can be connected thereto at an input angle of 45 degrees to the half mirror. - View Dependent Claims (11, 12)
