Implementation of a Universal Drive Blind Fastening System During Transition from Manual to Automated Assembly 2002-01-2627

The implementation of automated fastening processes is often complicated by variations in the fastener-to-tool interface, and by differences in the installation tooling required by manual and automatic methods. The goal of this paper is to reduce the complexity of such an implementation.
New technologies exist which enable the development of a single mechanism for installing any screw-actuated fastener both manually and robotically. End-effector integration is accomplished most effectively by simple methods, one-sided installation, and uniformity of fastener interface. The replacement of complex systems with one-piece fasteners increases assembly speed and reduces handling difficulties.
This paper will describe the main elements required in developing manual tools and robotic end-effectors that use identically driven fastener inventories.
The issues of robotic programming, access, alignment, fastener feed, and F.O.D. pickup will also be discussed. The necessity of maintaining proper orientation and alignment calls for a minimum of vibration or shock load throughout the fastening process. Fastener end-effectors must be integrated with other automated modules such as drilling, probing and sealing units in order to accomplish a full implementation.
