Deflection Device for Selective Laminating Film Adhesion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laminating methods result in increased complexity and waste due to the application of adhesive to entire laminating film elements, leading to higher costs and environmental burden, as non-laminated areas require significant process engineering to avoid adhesive contact.
Innovation Solution
A deflection device with corrugated or waffle-shaped cavities in the laminating tool allows for temporary avoidance of adhesive contact in non-laminated areas, combined with a fluid rinsing system for effective cooling and separation using sealing elements and vacuum pressure, enabling efficient production of film-free areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If adhesive is applied to the entire laminating film element, then complete coverage is achieved, but adhesive waste increases and costs rise
Solution Approach 1:
The laminating film element is divided into laminating areas and non-laminating areas through the deflection device, allowing adhesive to be applied only where needed. The deflection device creates physical separation between these areas, enabling selective lamination and reducing adhesive waste on non-laminating portions.
Solution Approach 2:
The deflection device extracts or removes non-laminating areas from the contact surface with the component by deflecting them into a recess. This extraction prevents adhesive from bonding these areas to the component, eliminating adhesive waste in those regions while maintaining complete coverage in laminating areas.
2Loss of substance
If process engineering is undertaken to create film-free areas, then adhesive contact is avoided, but device complexity increases
Solution Approach 1:
The deflection device serves as an intermediary mechanism between the adhesive application system and the component. It provides a simple structural solution using a recess and deflection device to manage adhesive contact, avoiding complex process engineering while still achieving adhesive waste reduction.
Solution Approach 2:
The deflection device creates local structural variations in the tool, with recesses positioned at specific locations corresponding to non-laminating areas. This local structural adaptation allows for adhesive waste reduction without requiring complex overall process changes, maintaining simplicity while achieving the desired effect.
3Manufacturing precision
If adhesive is applied to large areas, then complete lamination is achieved, but environmental burden increases
Solution Approach 1:
By segmenting the laminating film into laminating and non-laminating areas through the deflection device, adhesive is applied only where bonding is required. This reduces the total amount of adhesive used, thereby decreasing environmental burden from adhesive waste while maintaining uniform lamination quality in the laminating areas.
4Temperature
If deflection device with cavities is used, then adhesive cooling is improved, but tool structure becomes more complex
Solution Approach 1:
The deflection device incorporates cavities or recesses in the tool structure that provide increased surface area for adhesive cooling. These cavities allow air or cooling fluid to circulate through the adhesive layer, enhancing heat dissipation. The structural complexity is minimized by integrating these cavities into the existing tool design rather than adding separate cooling systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces adhesive waste, simplifies the process, and enhances the stability and cooling of adhesives, allowing for cost-effective and reliable creation of film-free areas on laminated components.
Implementation Method 1
If the deflection cavities of the deflection device are designed as vacuum cavities, the laminating film element can be partially deflected particularly easily in accordance with the invention
Implementation Method 2
a fluid flushing device on the apparatus, by means of which the spaces between the substrate or component to be laminated and the laminating film element can be flushed with a fluid, preferably air. This allows for even more effective cooling of the adhesive
Implementation Method 3
the deflection cavities of the deflection device have at least partially ribbed or waffle-shaped walls. This allows for an increase in the surface area of the tool and especially of the laminating film element, which in turn leads to more effective cooling of the adhesive present there
