10 questions that anyone developing an assembly application for pliable parts needs to ask (part 1).

It takes very little effort for pliable components such as cable harnesses and hoses to be deformed. When it comes to the assembly of pliable components, adaptivity is vitally important – previously one of the core competencies of human labour. We will provide you with an insight into a test in which pliable components were assembled by automated means. To start with, however, there are some key questions.

EDAG PS frequently focuses on areas relating to lightweight robots and human-robot collaboration. In this series, we combine the two. Our mission: to bring assembly processes into the 21st century!

Stable and pliable (or dimensionally unstable) components

General automation usually involves stable components with fixed positions, at which the component can be picked up, deposited and processed. They cannot be changed and cannot change themselves.

But what happens with a component made of soft rubber, and not stable sheet metal? How do you deal with the fact that the geometry of the component is constantly changing? Suddenly, the fixed positions are worthless.

Robots and assembly shops

For this reason, only dimensionally stable, metal materials are processed by robots in the body assembly shop. By contrast, very few robots are found in the assembly of pliable components. This includes, for example, fitting seals, belts, covers and fabric trims, positioning foot mats, or plugging connectors at the end of cables into the appropriate sockets.

If we were able to install pliable components by automated means, it would be possible to automate an area in which everything is done manually.

10 questions on the way to automated assembly

In the next few weeks, we will be providing you with insights into a student’s thesis dealing with an experiment in which the automated assembly of “dimensionally unstable parts” is set up and managed.

Zuvor müssen wir uns aber die folgenden Fragen stellen:

  1. Welcher Prozess bietet sich an?
  2. Wie können wir die Werker entlasten?
  3. Von welcher Stabilität des Bauteils kann ausgegangen werden?
  4. Von welcher Labilität des Bauteils kann ausgegangen werden?
  5. Wie lässt sich die labile Geometrie stabilisieren, damit das Bauteil verarbeitet werden kann?
  6. Wie soll der Versuchsaufbau aussehen?
  7. Wenn mit Spannrollen gearbeitet wird: wie viele und wie sind sie anzuordnen?
  8. Ist es möglich, einen einfachen Versuchsaufbau im Labor nachzubilden?
  9. Orientierung am Hersteller oder an einem bestimmten Modell?
  10. Wie ist der Prozess oder das Werkzeug robotergerecht umzugestalten?
