ScanVision™ Application
Cutting Edge Vision-assisted Precision Laser Processing Solution
Hylax’s proprietary ScanVision Technology combines a vision camera system & a laser system together to offer high precision laser processing (welding, marking, cutting, drilling, surface processing etc).
By positioning the camera inline with the laser path, visible light for the vision camera travels in the same path as the laser beam, through the galvanometers beam positioning system. This makes it possible to achieve real-time vision compensation of work piece drift or fiducial find, with accuracy up to 3 micron in milliseconds. All tolerances of conventional vision-assisted laser systems such as XY table, F-Theta lens, galvanometers positioning errors, work piece and jig tolerance, etc. are there fore eliminated.
ScanVision Features & Advantages
- In-line visible light and laser beam near perfect coincident to each other – near zero tolerance between laser beam and vision light path.
- High Speed (movement in milliseconds) & High Accuracy (in microns) large area coverage by movement of galvanometers to perform:
- Vision Check
- Fiducial Find
- Pre/Post Mark Inspection
- Laser Processing
- 2D data matrix verification
- Orientation check
- Active X, Y and theta drift work piece misalignment compensation without moving the work piece.
- No need for expensive jig and fixture for work pieces to achieve accurate laser processing.
- Real-time point-of-mark insepction & viewing before/after marking.
- No need to shuttle work piece between laser and camera positions (only galvanometers move) resulting in:
- Reduced processing time, delivering a much higher throughput.
- Small work envelope requirement (Compact design).
- Elimination of tolerances associated with mechanical movements.
- Vision check and laser processing performed almost simultaneously.
- Proven Software Interface in Visual Basic, C, Ethernet and RS232 to link with 3rd party software for complex solution and customization.
