Abstract
We have developed a one-axis on-the-fly system that can continuously process a large area by using a laser scanner. Existing laser processing using scanner systems can be used for precision processing, but have a limitation in the area of processing. To supplement this shortcoming, a step and scanning technique using a stage has been developed. This technique can process a large area in such a way that, after laser processing, the stage moves repetitively; however, this method has a demerit in that processing quality in the part between the scan areas is not even. To solve this problem, there is a method of synchronizing the scanner and the stage. This study developed an on-the-fly system that synchronizes the one-axis stage and the two-axis scanner. Also, in synchronized processing, the velocity of the stage due to the velocity of fabrication is very important. If the velocity of the stage is not proper, the laser processing deviates from the scanner work area. We proposed an algorithm in which, using a cell decomposition method, the velocity of the stage is automatically calculated by compensating for the acceleration/deceleration time occurring in the stage rotation and the reverse rotation due to the velocity of the fabrication. We compared the step and scanning method to the on-the-fly method through a low-frequency experiment and proved that the latter has better precision for the boundary of the scan area; we further analyzed the precision by using a large area marking and an overlapping experiment. In addition, by measuring encoder output signals, a compensation algorithm for the stage acceleration/deceleration time was verified.
