As the key equipment of grain packaging,the stability and precision of dicing machine play a key role in cutting precision and quality.Based on this,the Y axis and Z axis,which is the key component of high performance and high performance requirements,are selected to type selection design,optimization analysis and precision control.At present,the domestic and foreign research on the dicing machine is not enough,so it is of great significance to improve the quality and yield of the chip.In this paper,based on the design and development of the dicing machine,the key Y axis and the Z axis are designed,optimized and analyzed,and the following four aspects are mainly studied:(1)Selection calculation analysis and structure design.According to the characteristics and requirements of dicing machine,through calculation,selection of the research base,shaft guide,screw,grating ruler,motor and other components,which can meet the requirements of the design of structure and precision,and the Y and Z axis of the base and other components designed to meet the design requirements.(2)Modeling and finite element dynamic and static analysis.SolidWorks used to establish the three-dimensional model,and then use ANSYS Workbench to establish the finite element model,and finite element analysis,simulation and real constraints,finally obtained the static Y and Z axis analysis results,verify whether meet the static requirements;transient dynamics analysis and after considering the influence of change of acceleration of structure the results obtained,dynamic analysis.(3)Structural optimization design based on finite element analysis.Considering the safety threshold and to meet the strength and improve the existing structure stiffness under the premise.Firstly,using topological optimization method selection optimization scheme,and then establish the mathematical model of response surface analysis and sensitivity analysis to optimize the size,and verified by BP neural network,and ultimately achieve the purpose of light weight analysis the results of optimization,to verify whether it meet the requirements of structural strength.(4)Precision control and error compensation.The design of the Y axis and the total machine precision,first precision distribution calculation in machining precision reasonable,further improve the accuracy of interferometer through the closed loop control of laser,the motion error in the process of error detection and error compensation until finally meets the requirement of accuracy,precision test and prototype test,verify the accuracy control and error compensation effect.This paper selects the Y and Z axis high precision dicing machine requirements as the research object,through the analysis of knowledge and theory and the combination of experiment and simulation,improve the accuracy of dicing machine,solving the practical engineering problems is closely related to the production practice for engineering optimization problems need to consider similar lightweight solutions are put forward reasonable.Has an important guiding significance for optimization design and precision control compensation.
