High Precision Position and Dimension Sensors Suitable for Manufacturing

9424569 Busch-Vishniac该项目将使用基于横向效应硅光敏二极管(PSD)技术的新型六自由度传感器来测量制造的机械部件的尺寸。对于大批量生产环境，创新之处在于满足技术性能规格。在+/-30 mm的线性范围内的0.01-0.1微米量级的分辨率和在+/-2度的旋转范围内的0.01角秒量级的角度分辨率是可能的，并且由于这些主要是模拟传感器，目标是每秒进行1000次测量，以便在大批量生产中将它们用于反馈过程控制是可行的。该项目将解决实现这些与制造相关的技术目标的三个重要主题：集成传感器系统的误差分析、安装在制造环境中时的实施和稳健性问题，以及制造部件的尺寸和位置检测。为了测试健壮性问题，调查人员将与一家公司合作，在试生产环境中开发和安装原型系统。该项目的成功完成将以较低的成本提供一种新的分辨率、高速、非接触式传感器技术。这使得能够在制造和装配系统中对尺寸或机械特征进行闭环控制，以生产大容量和高质量的产品和部件。

9424569 Busch-Vishniac This project will use a new six degree of freedom sensor based on lateral effect silicon photo sensitive diode (PSD) technology, to measure dimensions on manufactured mechanical components. For a high volume production environment, the innovation is in meeting the technical performance specifications. Resolutions on the order of 0.01-0.l micrometer over a linear range of +/- 30 mm and angular resolutions on the order of 0.01 arc-seconds over a rotation range of +/- 2 degrees are possible, and because these are primarily analog sensors, the goal is to make 1000 measurements a second so that it is feasible to use them for feedback process control in high volume production. This project will address three topics of importance in achieving these technical goals relevant to manufacturing: an error analysis of the integrated sensor system, implementation and robustness issues when installed in a manufacturing environment, and detection of dimensions, as well as position, of a fabricated part. To test the robustness issues, the investigators will work with a company to develop and install a prototype system in a pilot manufacturing environment. Successful completion of this project will provide a new resolution, high speed, non-contact sensor technology at modest cost. This enables closed loop control of dimensional or mechanical features in manufacturing and assembly systems that produce high volume and high quality products and components.
