LASER WELDING APPARATUS AND METHOD OF CONTROLLING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033846 titled 'LASER WELDING APPARATUS AND METHOD OF CONTROLLING THE SAME

Simplified Explanation

The abstract describes a laser welding apparatus that includes a stage for seating two structures to be welded, a vision camera positioned above the stage to capture an image of the welding target region, and a controller to adjust the camera's settings. The controller obtains RGB values from selected regions of interest in the sample image and compares them with reference RGB values from a predetermined reference image to adjust the camera's settings.

  • The laser welding apparatus includes a stage for seating the structures to be welded and a vision camera positioned above the stage.
  • The vision camera captures a sample image indicating the welding target region where the two structures come into contact.
  • The controller adjusts the setting parameters of the vision camera.
  • The controller obtains a sample RGB value from each selected region of interest in the sample image.
  • The controller compares the sample RGB value with a reference RGB value obtained from corresponding reference regions of interest in a reference image.
  • The controller adjusts at least one of the setting parameters based on the comparison.
  • The vision camera is set according to the adjusted setting parameters.

Potential applications of this technology:

  • Laser welding in manufacturing processes, such as automotive or aerospace industries.
  • Precision welding of small or delicate structures, such as medical devices or electronics.

Problems solved by this technology:

  • Ensures accurate alignment and contact between the two structures to be welded.
  • Improves the quality and consistency of the welding process.
  • Reduces the need for manual adjustments and human error.

Benefits of this technology:

  • Increases efficiency and productivity in laser welding operations.
  • Enhances the precision and reliability of the welding process.
  • Reduces the likelihood of defects or failures in the welded structures.


Original Abstract Submitted

a laser welding apparatus includes a stage on which a first structure and a second structure, targets of a laser welding process, are seated, a vision camera located above the stage and obtaining a sample image indicating a welding target region in which the first structure and the second structure come into contact, and a controller adjusting setting parameters of the vision camera. the controller obtains a sample rgb value from each of a plurality of regions of interest selected from the sample image, compares the sample rgb value with a reference rgb value obtained from each of reference regions of interest defined in the same location as the plurality of regions of interest in a predetermined reference image, to adjust at least one of the setting parameters, and sets the vision camera.
