Integrated Vision System from Datron
Vision system for machining center.
Milford, NH — Datron Dynamics, Inc. has released a vision system for high-speed machining applications — the Datron IVS (Integrated Vision System) — housed in a rugged metal chassis for industrial applications. It is mounted to the Z-axis of its machining centers for locating fiducials and crop marks as the camera moves to a pre-defined location or window.

Any edge-to-fiducial irregularities are fed into the machining data and compensated for dynamically, before the machining begins. 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.

According to the company, the new integrated system makes setup easy and fast. The operator places the part on the bed — using the company's proprietary VacuMate (vacuum table) workholding or a fixture with pins. The pins insure that the part is on the fixture properly. The camera then scans for fiducials, edges and images and feeds the data into Windows®-based control software.

Irregularities are compensated for dynamically before the machining starts, insuring quality and uniformity.

If the camera determines that the part is not positioned correctly (perhaps because the operator has not seated the fixture in the correct location on the machining table) then the program automatically pauses and asks the operator to abort or retry. Or, the software can adjust for the variance and cut usable parts even when the blank is not positioned properly. Where screen-printed sheet material is concerned, there is sometimes "stretch" in the artwork that cannot be overcome by traditional machining centers. This new system can locate fiducials and crop marks within 20mm variance, allowing manufacturers to overcome the inconsistencies of screen-printing to yield quality uniform parts and minimize waste. The system will also locate fiducials on printed circuit boards, for identification, inspection, position control and fixture location. Data is fed into the machining center control for dynamic compensation. The software automatically adjusts for skew and image-to-edge variance. It allows for teaching of new fiducials, crop marks or ticks and yields compatibility and flexibility to the manufacturing process. IVS reduces and even compensates for improper setups.

The system includes camera with light ring, images and cross-hairs on display, live pictures, teaching (teach in) of new fiducials, captures and stores pictures and fiducials, image calibration, adjustment of brightness, gain and contrast (manual and automatic), 20 x 16mm display window, operating distance approx. 100mm, resolution 1280 x 1024 pixels, accuracy ±0.02mm (depending on quality of fiducials), software based on HALCON Vision Tools®.
