Any edge-to-fiducial irregularities are fed into the machining data and compensated for dynamically before the machining begins. Further, by locating multiple fiducials, the system can automatically adjust for skew or image-to-edge variance. In instances where a fiducial or crop mark is not found, the program pauses, and the operator is alerted and given the option to abort or retry.
The system is suited for locating fiducials on Printed Circuit Boards (PCB), identification, inspection, position control and fixture location. Data is fed into the machining center controller for dynamic compensation. It allows for teaching of new fiducials, crop marks or ticks and it yields compatibility and flexibility to the manufacturing process. According to the company, the system reduces and compensates for improper setups.
Features include a camera with light ring, images and cross-hairs on display as well as live pictures. Capabilities include teaching (teach in) of new fiducials, capturing and storing pictures and fiducials, image calibration, adjustment of brightness, gain and contrast (manual and automatic). The system features a 20- × 16-mm display window, an operating distance of approximately 100 mm, a resolution of 1,280 × 1,024 pixels, accuracy to ±0.02 mm (depending on quality of fiducials) and software based on Halcon Vision Tools.
