锡膏印刷机并联平台定位算法的研究 总被引:5,自引:1,他引:4
锡膏印刷作为表面贴装技术(Surface Mount Technology,SMT)工艺流程的第一道工序,也是SMT质量的基础.针对平台纠偏定位精度不高而导致印刷后PCB锡膏偏移的问题,从全自动锡膏印刷机并联平台的结构分析出发,根据其运动特性,建立平台的运动分析模型,结合最小二乘法原理,给出了一种定位速度快、精度高的定位算法.实验与应用中,通过机器视觉系统获取PCB与钢网上Mark坐标差值,经该算法定位后结合误差理论分析定位误差.结果表明,该算法可一次性完成纠偏·不仅节:节省了平台机械定位时间,而且有效避免了并联平台分步运动时的耦合误差,平台重复定位精度稳定在±10μm、±0.005°以内. 相似文献

Breakage detection of small-diameter tap using vision system in high-speed tapping machine with open architecture controller 总被引:1,自引:0,他引:1
In this research, a vision system for detecting breakages of small-diameter taps, which are rarely detected by the indirect
in-process monitoring methods such as acoustic emission, cutting torque and motor current, was developed. Two HMI (Human Machine
Interface) programs to embed the developed vision system into a Siemens open architecture controller, 840D, were developed.
They are placed in sub-windows of the main window of the 840D and can be activated or deactivated either by a softkey on the
operating panel or the M code in the NC part program. In the event that any type of tool breakage is detected, the HMI program
issues a command for an automatic tool change or sends an alarm signal to the NC kernel. An evaluation test in a high-speed
tapping machine showed that the developed vision system was successful in detecting breakages of small-diameter taps up to

MES (Manufacturing Execution System) is a powerful production management tool supporting production optimization from the process initiation to the final shipment. It not only transmits the production information to production planning systems like ERP (Enterprise Resource Planning) and SCM (Supply Chain Management) in real-time, but also orders the planned production data to the production site. It is a production management system which plans and executes based on the production data in the field, thus it must be operated with a data acquisition system which gathers the accurate field data in real-time. This study deployed the data acquisition system and HMI (Human Machine Interface) system to collect real-time equipment data through the interface with the equipment to develop MES, and the developed system was applied to the machine tool for verification of its effectiveness. The test indicated that the equipment operating time and other operating data of the equipment could be processed without the interference of the workers. The developed data acquisition system and HMI can be applied to other equipment by using different sensors. 相似文献
