Fiber Laying Head Support Roller for Gap-Free Composite Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber laying systems suffer from inaccuracies and material damage due to the fiber laying head plunging into gaps in the forming tool surface, leading to defects and increased costs in fiber composite component production.
Innovation Solution
A fiber laying head with a support element spaced apart from the laying unit ensures contact with the tool surface, preventing the laying unit from plunging into gaps, and a force element maintains contact pressure, allowing deposition across tool surface irregularities without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the depositing roller is pressed towards the tool surface to ensure contact, then deposition accuracy is improved, but the roller plunges into gaps causing material damage and excessive stress
Solution Approach 1:
The fiber laying head is segmented into multiple functional units: a support element (support roller) and a depositing unit (depositing roller). The support element is positioned at a distance from the depositing unit, allowing it to contact the tool surface and prevent the depositing roller from plunging into gaps, thereby resolving the contradiction between maintaining contact pressure and avoiding material damage.
2Productivity
If the depositing roller is pressed into gaps to maintain contact, then continuous deposition is improved, but material overhangs and defects occur
Solution Approach 1:
The support element acts as an intermediary between the depositing unit and the tool surface. It provides the necessary contact and support function, allowing the depositing roller to maintain its position above the tool surface without plunging into gaps, thus enabling continuous deposition while preventing material overhangs and defects.
3Reliability
If the laying head is pressed towards the tool surface to ensure fiber material contact, then deposition reliability is improved, but the system encounters excessive stress when encountering surface irregularities
Solution Approach 1:
The fiber laying head is divided into a support element and a depositing unit positioned at a distance from each other. The support element contacts the tool surface to provide stability and prevent the depositing unit from encountering excessive stress when surface irregularities are present, thereby maintaining deposition reliability without excessive force application.
