Aiming at the problem of low efficiency of the traditional semi-auto LCM film laminating machine,the research and development needs for the online automatic laminating machine which film rhythm was 35 s/pcs were put forward.Based on the analysis of the core technology index of the laminating machine,a preliminary plan of online automatic high speed laminating machine was proposed.The operation times on the film supply side and the LCM supply side of the laminating machine were analyzed by the time series analysis method.Then,the structures of the film supply side and the LCM supply side were optimized based on the timing analysis results.The consistency of the work schedule on both sides was ensured.The film rhythm of the final machine plan could be 30 s/pcs.Finally,the virtual prototype was designed based on this plan.And this laminating machine was made in the research and development of enterprise cooperation.At present,the laminating machine is used in the enterprise production line.It improves the production efficiency and quality of enterprises greatly.
