Abstract
Provided is a laser welding process system including a vision camera for recognizing a welding location of a material deposited on a welding station; a laser scan head for performing a welding process on the material through a laser light source when the welding location of the material is recognized by the vision camera; and a controller for temporarily changing an initial set value of the vision camera to perform the welding process when the welding location of the material is not recognized by the vision camera and next making a return to the initial set value, and for modifying the initial set value of the vision camera when the number of times that the welding location is not recognized exceeds a preset number.
Claims9
A laser welding process system, comprising:
- a vision camera for recognizing a welding location of a material deposited on a welding station;
- a laser scan head for performing a welding process on the material through a laser light source when the welding location of the material is recognized by the vision camera;
- and
- a controller for temporarily changing an initial set value of the vision camera to perform the welding process when the welding location of the material is not recognized by the vision camera and next making a return to the initial set value, and for modifying the initial set value of the vision camera when the number of times that the welding location is not recognized exceeds a preset number.
An operating method of a laser welding process system, the operating method comprising the steps of:
- feeding a material onto a welding station;
- moving a laser scan head to a welding location of the material;
- operating a vision camera for recognizing the welding location of the material;
- and
- recognizing the welding location of the material, the recognizing comprising:
- performing a welding process through the laser scan head to run a production line when the welding location is recognized by the vision camera;
- or switching to an operator mode when the welding location is not recognized by the vision camera,
- wherein the switching to the operator mode comprises:
- comparing a preset number with an accumulated number of times that the switching to the operator mode is performed;
- and
- temporarily resetting, when the accumulated number is equal to or less than the preset number, an initial set value of the vision camera and performing the welding process on the material to run the production line.
