Abstract
A computer-implemented method for monitoring a workpiece being manufactured using an automated welding system. These technologies can real-time monitor, read, or interrogate a workpiece or a substrate on which the workpiece is positioned, as the workpiece is moved past a directed energy source, or vice versa. The method can be used with an automated welding system for standoff distance monitoring and control, which can be responsive, dynamic, and in real-time. These technologies can use a feedback controller to responsively and dynamically control the standoff distance in real-time based on data from the standoff distance measurement system.
Claims20
A computer-implemented method for monitoring a workpiece being manufactured by an automated welding system, the computer-implemented method comprising:
- causing an optical signal to be emitted from a signal emitter onto a surface of the workpiece, the optical signal indicating a section of the workpiece;
- obtaining data relating to the surface of the workpiece from a signal detector, the data including one or more reflections from the surface of the workpiece;
- inputting the data to a machine-learned model;
- receiving, from the machine-learned model, an identification of a reflection of the one or more reflections that corresponds to the optical signal indicating the section of the workpiece;
- and
- determining one or more geometric properties of the section based on the reflection.
A system comprising:
- a signal emitter;
- a signal detector;
- one or more processors;
- and
- non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the system to perform operations comprising:
- causing an optical signal to be emitted from the signal emitter onto a surface of a workpiece, the optical signal indicating a section of the workpiece;
- obtaining data relating to the surface of the workpiece from the signal detector, the data including one or more reflections from the surface of the workpiece;
- inputting the data to a machine-learned model;
- receiving, from the machine-learned model, an identification of a reflection of the one or more reflections that corresponds to the optical signal indicating the section of the workpiece;
- and
- determining, based on the reflection, one or more geometric properties of the section.
