【摘要】：决定设备市场竞争力有两个主要因素,一是生产成本,一是生产效率。PSA贴敷机实现了机器贴敷代替手工贴敷的自动化变革,而进一步研究开发新一代设备的过程中,则要从提高设备生产效率,降低设备生产成本的角度出发。论文从改变机械结构的角度降低成本,在保证设备贴敷精度的前提下,研究PSA贴敷机单驱形式的可行性。论文以PSA贴敷机为研究对象,针对其高精度、高速度的要求,分析了设备贴敷精度,提出了PSA贴敷机定位系统横梁变形是影响贴敷精度的重要因素之一。建立了横梁变形对贴敷精度影响的误差模型,得到了横梁沿运动方向的变形是影响贴敷精度的关键因素。对PSA贴敷机定位系统横梁进行动力学分析,通过计算得到横梁的位移变形量,验证了误差模型。根据误差模型,通过Pro/E和Ansys Workbench协同仿真的方法设计了满足PSA贴敷机单驱形式的横梁结构并进行了参数优化。优化结果成功指导了PSA贴敷机单驱形式样机的研发,完成调试并满足了客户需求。PSA贴敷机单驱形式的研发成功,为设备节省了26%的制造成本,取得了可观的经济效益和良好的社会效益。根据参数优化的方法,对PSA贴敷机双驱形式横梁结构做了轻量化设计。根据误差模型,得到PSA贴敷机双驱形式贴敷精度还有35%提高空间的结论,为PSA贴敷机双驱形式后续的研究提供了参考依据。
[Abstract]:There are two main factors that determine the competitiveness of equipment market, one is the production cost, the other is that the production efficiency. PSA padding machine has realized the automatic transformation of machine sticking instead of manual sticking, and in the process of further research and development of the new generation of equipment, To improve the efficiency of equipment production, reduce the cost of equipment production from the point of view. From the angle of changing the mechanical structure, this paper studies the feasibility of single drive of PSA sticking machine on the premise of ensuring the precision of equipment sticking. Aiming at the requirement of high precision and high speed, the paper analyzes the precision of PSA padding machine, and points out that the deformation of the beam in the positioning system of PSA padding machine is one of the important factors that affect the precision of laminating machine. The error model of the influence of beam deformation on the laminating accuracy is established. The key factor affecting the laminating accuracy is the deformation of the beam along the moving direction. The dynamic analysis of the beam of the positioning system of the PSA padding machine is carried out. The displacement and deformation of the beam are calculated and the error model is verified. According to the error model, the cross beam structure satisfying the single drive form of PSA padding machine is designed by the method of Pro/E and Ansys Workbench cooperative simulation, and the parameters are optimized. The optimized results have successfully guided the research and development of the single-drive prototype of the PSA sticking machine, completed the debugging and successfully developed the single-drive form of the PSA sticking machine, and saved the manufacturing cost of the equipment by 26%. Considerable economic benefits and good social benefits have been obtained. According to the method of parameter optimization, the light weight design of double drive beam structure of PSA padding machine is made. According to the error model, the conclusion that there is 35% more space to improve the precision of double drive for PSA sticking machine is obtained, which provides a reference for the further study of double drive form of PSA padding machine.
