Technical Field

[0001] The present invention relates to the technical field of laser welding focal length measurement and calibration devices, and more particularly to a laser welding focal length measurement and calibration device for a robot of an automobile seat frame. Background Art

[0002] In the production of automobiles, the automobile seat needs to be welded in the vehicle by laser welding technology. The specific implementation method is as follows: Laser with a certain power is transmitted from a laser source to a programmable focusing optical device (PFO) through an optical fiber. The focusing lens of the PFO focuses the laser, and the reflecting lens group of the PFO rotates to make the focal point move on the workpiece surface along a required trajectory to form a weld seam. Currently, the laser welding focal length measurement and calibration is to determine the focal point position by visually projecting a navigation light onto the workpiece surface. However, this method has the following defects: Due to the influence of the width of the navigation light and the diameter of the light spot, the method of visually observing to confirm the focal point position cannot meet the accuracy requirements, and it is easy to deviate during the welding process, resulting in the processing area exceeding the set area.
