A device for consolidating a thermoplastic preform, in particular a carbon fiber thermoplastic preform includes a heating element, e.g., an LED array, for heating the preform and a consolidation element, e.g., a consolidation roller, for exposing the preform to pressure and for cooling the preform.
A device for consolidating a thermoplastic preform, in particular a carbon fiber thermoplastic preform includes a heating element, e.g., an LED array, for heating the preform and a consolidation element, e.g., a consolidation roller, for exposing the preform to pressure and for cooling the preform. In order to consolidate the preform, the heating element and consolidation element are arranged and movable relative to each other in such a way that the preform can be exposed to pressure and cooled by the consolidation element after heated by means of the heating element.

1. A device for consolidating a thermoplastic preform, comprising: a heating element for heating the preform; anda consolidation element for exposing the preform to pressure and for cooling the preform,wherein, to consolidate the preform, the heating element and consolidation element are arranged and are movable relative to each other in such a way that the preform is exposed to pressure and cooled by the consolidation element after being heated by the heating element,wherein the consolidation element comprises at least two adjacent consolidation rollers,wherein the heating element and the consolidation rollers are configured and arranged to be moved along the preform in such a way that the preform is heated region by region by the heating element, and subsequently pressurized and cooled by the consolidation rollers,wherein the consolidation rollers are configured and arranged to be guided along the preform by a web guide,wherein the web guide comprises a guide groove and a guide arm, at least one of the heating element and the two consolidation rollers being arranged on the guide arm,wherein a shape of the guide groove corresponds to a shape of the preform and enables guiding the consolidation rollers along the shape of the preform,wherein the guide arm comprises a connecting part having a first longitudinal end and a second longitudinal end opposing the first longitudinal end, the heating element and the two consolidation rollers being attached to the first and second longitudinal ends, respectively, thereby being spaced apart from each other,wherein the guide arm further comprises a guide part joined to the connecting part at a right angle to form a single part, and the consolidation rollers are mounted at a first longitudinal end of the guide part facing the connecting part,wherein the guide part is, at a second longitudinal end facing away from the connecting part, hinged in the guide groove, andwherein the heating element is pivotably secured to the connecting part so that the heating element can pivot around a longitudinal axis of the heating element, so that the preform is radiated at various angles, and can thus be heated at varying intensities. 2. The device according to claim 1, wherein the heating element comprises light-emitting diodes (LEDs). 3. The device according to claim 2, wherein the LEDs are combined into an LED array with a flat configuration. 4. The device according to claim 1, wherein the web guide is adjusted to varying material thicknesses of the preform. 5. The device according to claim 1, wherein the device is configured for acquiring at least one of the pressure and temperature on a contact point of the consolidation element and preform. 6. The device according to claim 1, wherein the consolidation roller comprises several roller segments. 7. The device according to claim 1, wherein the consolidation roller comprises a flexible material, where contact with the preform is provided.
