Abstract
A nozzle for applying a bead of material onto a component or a substrate. A nozzle body has a wall that defines a nozzle duct between a first end and a second end. A first nozzle discharge opening is formed at the second end and connected to the nozzle duct. A second nozzle discharge opening is connected to the nozzle duct and is introduced into the wall at the second end.
Claims10
A nozzle for applying a bead of material onto a component or a substrate, comprising:
- a nozzle body with a wall that defines a nozzle duct between a first end and a second end;
- a first nozzle discharge opening formed at the second end and connected to the nozzle duct;
- and
- a second nozzle discharge opening connected to the nozzle duct and introduced into the wall at the second end,
- wherein the nozzle is configured to be positioned in a first position via which a back pressure causes the material to emerge from the second nozzle discharge opening, and in a second position via which a lack of back pressure causes the material to emerge from the first nozzle discharge opening.
An application device for applying a bead of material onto a component or a substrate, comprising:
- a nozzle comprising:
- a body with a wall that defines a nozzle duct between a first end and a second end,
- a first nozzle discharge opening formed at the second end and connected to the nozzle duct, and
- a second nozzle discharge opening connected to the nozzle duct and introduced into the wall at the second end;
- a positioning system configured to move the nozzle translationally;
- a gear pump configured to convey the material into the nozzle duct of the nozzle;
- and
- a height-measuring system operable to measure a spacing between the second end of the nozzle and an application surface of the component or the substrate,
- wherein the application device positions the nozzle in a first position via which a back pressure causes the material to emerge from the second nozzle discharge opening, and in a second position via which a lack of back pressure causes the material to emerge from the first nozzle discharge opening.
A method for applying a bead of material onto a component or a substrate by means of a nozzle comprising:
- a body with a wall that defines a nozzle duct between a first end and a second end, a first nozzle discharge opening formed at the second end and connected to the nozzle duct, and a second nozzle discharge opening connected to the nozzle duct and introduced into the wall at the second end, the method comprising:
- ascertaining an accessibility of an application surface of the component or the substrate;
- measuring a spacing between the first end of the nozzle and the application surface;
- if a difficult accessibility is ascertained, positioning the second end of the nozzle at a spacing from the application surface such that a back pressure arises when the adhesive material is being applied onto the application surface, so that the material emerges from the second nozzle discharge opening;
- and
- if easy accessibility is ascertained, positioning the second end of the nozzle at a spacing from the application surface such that a back pressure does not arise when the adhesive material is being applied onto the application surface, so that the material emerges from the first nozzle discharge opening.
