Abstract
Description
この発明は一般に自動化された材料配置機およびその使用に関する。特に(限定されないが)、この発明は自動化された材料配置機によって置かれる材料を検査するためのシステムおよび方法に関する。
自動化された材料配置プロセスおよび機械は、航空宇宙産業および他の業界で大型の複合構造を製造する際に幅広く用いられている。自動化された目視検査を材料が置かれている間に実行できるシステムが利用可能である。これらのシステムは、検査のための機械の中断時間を低減するのに効果的であることが示されている。
この発明は、1つの局面では、材料配置機によって置かれる材料を検査する方法に向けられる。材料の区分を照らすために、材料に対して本質的に垂直な方向に材料上へ光を導く。区分内の不完全な部分をあらわにするために予め定められた角度で、区分上へレーザエネルギを投射する。
さまざまな実施例の以下の説明は例示的な性質のものに過ぎず、本発明、その応用例、または使用を限定することを意図するものでは全くない。
レーム204は、たとえば、新たに置かれる材料28の上に突き出るように圧縮ローラ36の上方および後方に取付けられるよう構成される。ミラー212が、たとえば45度の角度でフレーム204内に装着される。ミラー212は少なくとも部分的に銀を被せられて1つ以上の反射部分を提供する。
用され得る。
ラ230からの画像を同時に、たとえば画面54上のフレーム内で並んで、または異なるフレームで順次表示することができる。
