Potentiale von Laserbearbeitung an Flachglaselementen in einem Linienverbund

Abstract

In this thesis, the potential of laser technology for the processing of flat glass elements is examined in detail. The focus is not only on overcoming existing limits, but also on opening up new process sequences that could not be realized with conventional methods. A deep understanding of the laser processing of flat glass elements thus forms the basis for the future further development of industrial flat glass processing. Firstly, a comprehensive introduction to the material glass is given, with the most important flat glass elements such as toughened safety glass, laminated safety glass and insulating glass elements being explained in more detail. A particular focus is placed on the current conventional processes for processing and manufacturing these flat glass elements. In particular, the importance of edge quality and edge processing for elements such as toughened safety glass and laminated safety glass is emphasized. Complex conventional machining processes are required for perfect edge quality. However, the use of laser technology opens up new perspectives, as processes such as scoring, breaking, seaming and grinding can potentially be replaced by a single laser processing step. Finally, the process chains for manufacturing the individual flat glass elements using laser technology are examined and alternatives for process design are developed. It was shown that laser processing hardly allows any changes in the process chain for the production of insulating glass elements, whereas for toughened safety glass and laminated safety glass elements there are opportunities to significantly reduce the production line by integrating this technology. This opens up new opportunities in industrial glass processing, which reduce system length in the production line and maximize flexibility in flat glass production. Overall, this thesis offers a comprehensive overview of the possibilities of laser processing on flat glass elements and shows future potentials, especially in the line network, which are made possible by the integration of these technologies.
