【摘要】：近年来太阳能光伏产业迅速崛起,打破国外硅片切割设备的垄断成为国内该产业发展的重点,这使得硅片切割设备的设计与制造成为研究的核心。金刚石线切割机作为一种专用高精密数控机床设备,其装配阶段作为设备研发制造过程中的重要阶段,也是最后环节,它对设备性能与质量的影响尤为重要。传统装配工艺主要以二维视图与几何文字描述来指导工人的装配操作,工作量大且不利于工人解读与运用;此外,装配过程极易发生零部件间的碰撞干涉、装配路径无效等问题,导致装配环节出现反复拆装与返修的现象,使得设备的装配周期延长且难以保证装配质量。装配过程可视化技术,旨在使用计算机记录验证装配方案的可行性,记录装配过程,将其转化为三维可视化文件提供给装配现场,从而提高装配效率和保证装配质量。本文以金刚石线切割机为研究对象,对其装配过程可视化技术进行研究,分析并规划其装配工艺,对其装配过程中涉及到的关键技术进行深入研究,并在计算机平台上对其装配过程进行仿真,且将仿真结果以三维装配文档的形式进行输出,从而达到优化金刚石线切割机的装配过程,提高设备装配效率,保证设备装配质量的目的。首先,对金刚石线切割机的结构及装配特点进行了分析,初步拟定了其装配方案及装配工艺流程;归纳和总结了与装配工艺相关的装配方法、装配组织形式和装配技术等变量,并对设备重要部件的装配顺序进行了规划。其次,针对装配过程可视化的关键技术研究,提出使用装配层次模型表达产品的装配模型信息;采用可拆即可装的思想对设备的装配序列进行规划;采用交互式路径规划与自动查找路径相结合的方法对设备的装配路径进行规划;说明了装配仿真技术的原理,并采用基于层次包容盒的方法进行装配过程中的碰撞干涉检验。最后,在DELMIA平台上对金刚石线切割机进行了装配工艺过程仿真与人机工程仿真,并采用html语言结合3DVIA Composer软件进行了装配过程可视化三维文档的制作与输出,实现装配过程的现场培训与指导。
[Abstract]:In recent years, the solar photovoltaic industry has risen rapidly, breaking the monopoly of foreign silicon chip cutting equipment has become the focus of the development of the domestic industry, which makes the design and manufacture of silicon chip cutting equipment become the core of the research.Diamond wire cutting machine is a kind of special high precision CNC machine tool equipment. The assembly stage of diamond wire cutting machine is an important and final part in the process of equipment research and manufacture, and its influence on the performance and quality of the equipment is particularly important.The traditional assembly process mainly uses two-dimensional view and geometric description to guide the assembly operation of the workers, which is difficult for the workers to interpret and apply. In addition, the assembly process is prone to collision and interference between parts.The invalid assembly path leads to repeated disassembly and rework in the assembly process, which makes the assembly cycle of the equipment prolonged and the assembly quality difficult to be guaranteed.The assembly process visualization technology aims to use computer records to verify the feasibility of the assembly scheme, record the assembly process, and convert it into 3D visual files to provide the assembly site, thus improving the assembly efficiency and ensuring assembly quality.In this paper, the assembly process visualization technology of diamond wire cutting machine is studied, the assembly process is analyzed and planned, and the key technologies involved in the assembly process are deeply studied.The assembly process is simulated on the computer platform, and the simulation results are output in the form of 3D assembly documents, so as to optimize the assembly process of diamond wire cutting machine and improve the assembly efficiency of the equipment.The purpose of ensuring the assembly quality of equipment.First of all, the structure and assembly characteristics of diamond wire cutting machine are analyzed, and the assembly scheme and assembly process are preliminarily drawn up, and the relevant assembly methods, assembly organization forms and assembly technology variables are summarized and summarized.The assembly sequence of the important parts of the equipment is planned.Secondly, according to the key technology of assembly process visualization, the assembly model information is expressed by assembly hierarchy model, the assembly sequence of equipment is planned by the idea of detachable assembly.The method of interactive path planning and automatic searching path is used to plan the assembly path of the equipment, the principle of assembly simulation technology is explained, and the collision interference test in assembly process is carried out by using the method based on hierarchical containment box.Finally, the assembly process simulation and ergonomics simulation of diamond wire cutting machine are carried out on DELMIA platform, and the 3D document of assembly process visualization is made and output by html language and 3DVIA Composer software.Implement field training and guidance in assembly process.
