Abstract
To achieve universal welding of thermoplastic workpiece parts with simple equipment, an infrared light transmission welding method is disclosed in which simple polychromatic, incoherent infrared light is generated by a simple infrared light source and is directed through a first workpiece part to a weld point for the purposes of connection to a second workpiece part. In particular, the infrared light is directed through a transparent bracing element.
Claims18
A transmission welding method for welding a first workpiece part, which is formed at least partially from thermoplastic material, to at least one second workpiece part at a weld point, the method comprising:
- providing an infrared lamp within at least one bracing element in a form of a tube;
- a) bracing the first workpiece part and the second workpiece part by at least one bracing element and pressing the at least one bracing element onto the first workpiece part;
- b) directing, using an infrared lamp that is internal to the tube of the at least one bracing element, polychromatic, incoherent infrared light radiation through the at least one bracing element to the first workpiece part and through the first workpiece part to the weld point;
- c) setting a temperature of the at least one bracing element before, during, and/or after step b) to influence a temperature of at least one region of the first workpiece part;
- and
- moving the tube, with the infrared lamp contained therein, over the first workpiece part along a welding region;
- wherein the tube of the at least one bracing element is at least partially transparent to the infrared light radiation;
- wherein at least one region of the first workpiece part or all of the first workpiece part is formed from a thermoplastic fiber composite material;
- and
- wherein the infrared light radiation is directed through the thermoplastic fiber composite material of the first workpiece part to the weld point.
A transmission welding method for welding a first workpiece part, which is formed at least partially from thermoplastic material, to at least one second workpiece part at a weld point, the method comprising:
- a) bracing the first workpiece part and the second workpiece part by at least one bracing element, wherein:
- the at least one bracing element is rotatable about an axis of rotation;
- the at least one bracing element is roll-shaped, roller-shaped, spherical, or in a form of a rolling body;
- and
- b) directing polychromatic, incoherent infrared light radiation through the at least one bracing element to the first workpiece part and through the first workpiece part to the weld point;
- and
- c) setting a temperature of the at least one bracing element before, during, and/or after step b) to influence a temperature of at least one region of the first workpiece part;
- wherein the at least one bracing element is at least partially transparent to the infrared light radiation;
- wherein at least one region of the first workpiece part or all of the first workpiece part is formed from a thermoplastic fiber composite material;
- wherein the infrared light radiation is directed through the thermoplastic fiber composite material of the first workpiece part to the weld point;
- and
- wherein the at least one bracing element comprises multiple rigid segments, which are flexibly articulated to one another, in order to replicate a topology of the first workpiece part.
A transmission welding method for welding a first workpiece part, which is formed at least partially from thermoplastic material, to at least one second workpiece part at a weld point, the method comprising:
- a) bracing the first workpiece part and the second workpiece part by at least one bracing element, wherein the at least one bracing element comprises an infrared light source that is internal to the at least one bracing element;
- b) moving the infrared light source over the first workpiece part to direct polychromatic, incoherent infrared light radiation through the at least one bracing element to the first workpiece part and through the first workpiece part to the weld point along a welding region;
- moving the at least one bracing element, along with the infrared light course contained therein, over the first workpiece part, jointly with the infrared light source;
- and
- c) setting a temperature of the at least one bracing element before, during, and/or after step b) to influence a temperature of at least one region of the first workpiece part;
- wherein the at least one bracing element is at least partially transparent to the infrared light radiation;
- wherein at least one region of the first workpiece part or all of the first workpiece part is formed from a thermoplastic fiber composite material;
- and
- wherein the infrared light radiation is directed through the thermoplastic fiber composite material of the first workpiece part to the weld point.
