Abstract
A method for producing an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, The cavity is at least partially filled with an adhesive, and the components are aligned relative to one another such that at least sections of the pin project into the adhesive inside the cavity. A heating that is limited to the adhesive is carried out by means of a targeted, local introduction of heat into the adhesive in order to cure the adhesive.
Claims12
A method to produce an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, the method comprising:
- at least partially filling the cavity with an adhesive;
- aligning the first and second components relative to one another such that at least sections of the pin project into the adhesive inside the cavity;
- and
- introducing heat to the adhesive, after the aligning of the first and second components, in order to cure the adhesive, the heat introduced to the adhesive being limited via a targeted, local introduction of the heat into the adhesive,
- wherein the introduction of the heat is carried out by irradiation of the adhesive with laser radiation,
- wherein the adhesive is irradiated with the laser radiation from the infrared spectral range, and
- wherein the introduction of the heat into the adhesive takes place through an exposed adhesive surface of the adhesive, the exposed adhesive surface being exposed to ambient air.
A method to produce an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, the method comprising:
- at least partially filling the cavity with an adhesive;
- aligning the first and second components relative to one another such that at least sections of the pin project into the adhesive inside the cavity;
- and
- introducing heat to the adhesive in order to cure the adhesive, the heat introduced to the adhesive being limited via a targeted, local introduction of the heat into the adhesive,
- wherein the introduction of the heat is carried out by irradiation of the adhesive with radiant heat from an infrared radiator or a polychromatic radiation from an incandescent lamp or a halogen emitter.
A method to produce an adhesive connection between a first component and a second component, wherein the first component has at least one cavity and the second component has at least one pin, the method comprising:
- at least partially filling the cavity with an adhesive;
- aligning the first and second components relative to one another such that at least sections of the pin project into the adhesive inside the cavity;
- and
- introducing heat to the adhesive in order to cure the adhesive, the heat introduced to the adhesive being limited via a targeted, local introduction of the heat into the adhesive,
- wherein the introduction of the heat is carried out by application of a directed hot air stream to the adhesive.
