Structure Improved Design And Production Processes Research Of A Glass Cutting Machine

Precision glass cutting machine is considered to one of the most indispensablemanufacturing equipment in digital screen producing industry. The cutting precision directlyaffects the quality of production.This dissertation anlyzied the structure and cuttingtechnology design and experiment of one glass cutting machine.Based on finite-element analysis and cutting experiment optimal matching parametersbetween structure and cutting technology were obtained. Research on how to improvequalification rate and stability of products In large scale production were carried out.Applying ball screw drive, movement mechanism of main transmission designed wasanalyzed based on the actual demand Stiffness was computed and checked and the type wasselected of the main transmission parts ball screw pair. Influence factors were discussedduring the selection process of large ball screw pairs.The structure model of a workbench was established in this paper. The number of supportrods was reduced from forty-eight to thirty-six through finite optimization technology. Byexperiment and measurement, the possibility of improved structure and method were proved.Using the improved and assembled equipment as the experiment platform, a series of testswere performed such as changing cutting parameters, adapting different production processesetc. Optimal cutting parameters corresponding to specific type of glass were deducedaccording the experiment results. In terms of cutting processes, grasping method of oppositecorners was put forward. It was proved reliable and stable for glass cutting process andimproved cutting efficiency and production qualified rate.
