The Development of a Multi-Axis Magnetic Roller for Micro-Structure Transfer Embossing Processing Technology

Abstract This study proposed a processing technology using a multi-axis magnetic roller for micro-structure transfer embossing development. First, dynamics deduction and ANSYS numerical simulation were used to explore the impact of the upper axis on the medium and lower axis, under the conditions of different parameters. This study also-developed and established a multi-axis magnetic roller micro-structure transfer embossing system for analysis, simulation, and discussion, on the technological characteristics of the multi-axis auxiliary roller embossing replication and transfer embossing processing technology. By taking advantage of the feature of the uniform contact pressing of the magnetic roller during the roller embossing process, coupled with the coordinated force application of the three axis rollers, this study attempted to achieve complete, uniform transfer embossing and replication of the micro-structure during the roller embossing process. The results of multi-axis transfer embossing process simulation and experimental analysis showed that multi-axis transfer embossing technology can transfer and replicate a micro-structure on the roller in a more uniform and more effective manner. The proposed multi-axis magnetic roller micro-structure transfer embossing system can smoothly replicate a micro-structure by roller embossing with good replication moldability and optical performance characteristics, in order to sufficiently achieve uniform embossing results
