Continuous Laser Fabrication Method using Adaptive Cell Decomposition

A one-axis on-the-fly method was developed in order to extend the processing area of the existing laser processing systems. Demands for high precision laser processing with wide areas have been increasing in a number of applications such as solar cell batteries, display parts, electronic components, the automobile industry, and so on. However, ultra-high speed laser scanner systems are limited by the size of the scanning area, for example 50 x 50 mm. Even though a laser scanner system that can scan a wide area has been developed recently, the distortion of the scanning quality becomes more serious as the scan area increases. In this paper, an algorithm using adaptive cell decomposition is proposed. The developed method is differentiated from the existing step and scan method in that it can guarantee continuous stage movements, which may improve the processing speed and laser fabrication quality.
