Ultra-Precise Substrate Labeler

Prints and Places Labels with 70-Micron Accuracy Every 7.5 Seconds


High-Precision Automated Substrate LabelerThis ultra-precise system prints and accurately applies high-resolution bar-coded labels to both sides of a glass substrate using a combination of high-performance machine vision, multiple robots and sophisticated custom software.

Glass substrates coated with bio-medical samples are loaded into the system via carrier cassettes. The system scans the cassette to ensure there are no cross-slotted substrates, retrieves a substrate using a Genmark GRex3 robot, and places it onto a vacuum nest. A laser-ablated 2D matrix code on the substrate is used to determine the correct labels to print for the batch. The labels are printed and inspected, then picked using an Epson G6-450 SCARA robot fitted with a custom end-effector, and inspected again. The robot then makes positioning adjustments in relation to established fiducials prior to each placement. The system is capable of placement accuracy of +/- 70 microns.

Once the top-side of the substrate has been labeled, the system flips the substrate and places a second set of labels on the reverse side, achieving a front/back label registration of +/- 150 microns.
