Composite Ply Backing Removal Roller for Repeatable Peeling

The patent replaces manual mechanical peeling with a thermal field approach. A heating element is applied to the backing material interface, utilizing thermal energy to reduce adhesion strength and enable automated separation. This substitutes the purely mechanical hand-peeling process with a thermally-assisted automated system, resolving the contradiction between productivity improvement and device complexity.

The patent changes the physical parameter of temperature at the backing-material interface. By locally heating the interface between the backing and composite material, the adhesive properties are modified, reducing bond strength and enabling easier automated removal. This parameter change allows high-speed automated processing without requiring overly complex mechanical separation systems.

The patent introduces a thermal dimension to the backing removal process. Instead of relying solely on mechanical approaches that struggle with geometric variations, the system applies thermal energy which can adapt to different shapes and material properties. The heating element can conform to various geometries, and thermal diffusion naturally adapts to material variations, providing both automation capability and versatility.

The patent uses thermal energy as an intermediary between the automated system and the backing material. Rather than direct mechanical contact that must precisely replicate human hand movements, the thermal field acts as a mediator that uniformly affects the adhesive interface regardless of geometric variations, enabling automated operation while maintaining adaptability.

The patent applies heating locally only at the interface between the backing material and the composite material, rather than heating the entire composite structure. This localized thermal application reduces adhesion force where needed while maintaining the structural integrity and appropriate temperature of the composite material itself, preventing thermal damage while achieving effective peeling.

The patent employs rapid, controlled heating that quickly reaches the necessary temperature to reduce adhesion, performs the peeling action, and then immediately removes the heat source. This brief thermal exposure is sufficient to reduce peel force without allowing heat to accumulate and cause thermal damage to the composite material, effectively skipping through the thermal risk window.
