Abstract

This paper introduces a design for agile manufacturing workcells intended for light mechanical assembly of products made from similar components (i.e. parts families). We define agile manufacturing as the ability to accomplish rapid changeover from the assembly of one product to the assembly of another product. Rapid hardware changeover is made possible through the use of robots, flexible part feeders, modular grippers and modular assembly hardware. The flexible feeders rely on belt feeding and binary computer vision for pose estimation. This has a distinct advantage over nonflexible feeding schemes such as bowl feeders which require considerable adjustment to changeover from one part to another. Rapid software changeover is being facilitated by the use of a real-time, object-oriented software environment, modular software, graphical simulations for off-line software development, and an innovative dual VMEbus controller architecture. These agile features permit new products to be introduced with minimal downtime and system reconfiguration.

摘 要

本文介紹了一種用于制造工作單元光機(jī)電從類似的產(chǎn)品的裝配部件（即作出部分零件）靈活的設(shè)計(jì)。我們將敏捷制造定義為能夠?qū)崿F(xiàn)從裝配一個產(chǎn)品到另一個產(chǎn)品裝配的快速轉(zhuǎn)換?？焖儆布霓D(zhuǎn)換使得機(jī)器人的使用成為可能，并且依靠靈活的饋線上料皮帶和二進(jìn)制計(jì)算機(jī)視覺構(gòu)成估算，能夠靈活的裝配部分模塊化的夾子機(jī)和模塊化的裝配硬件。這種明顯的優(yōu)勢超過了如碗機(jī)需要相當(dāng)大的調(diào)整轉(zhuǎn)換從一個轉(zhuǎn)換另一部分的剛性喂養(yǎng)計(jì)劃?？焖佘浖D(zhuǎn)換是通過使用了一個實(shí)時的、面向?qū)ο蟮能浖h(huán)境,模塊化軟件,圖形模擬用于離線軟件開發(fā),和一個創(chuàng)新的雙重VME總線。這些敏捷特性使得新產(chǎn)品引入以最少的停機(jī)時間和系統(tǒng)重構(gòu)。
