1. A device for filling seal caps for sealing connecting elements in aircraft construction, said device comprising:
a filling unit with which sealant is filled into seal caps;
a support plate on which the seal caps are located; and
a control unit with which the movement of the filling unit and the support plate and the filling are regulated, wherein the control unit is configured to move the filling unit and the support plate in an XYZ coordinate system, wherein the control unit is configured to determine positioning of all the seal caps on the support plate and direct the seal caps correspondingly with the filling unit;
wherein the filling unit comprises an extrusion unit comprising a servo drive and a cartridge with sealant; and
wherein the seal caps are positioned on the support plate in a positioning pattern that corresponds to a positioning pattern of the connecting elements to be sealed;
wherein the device is configured to perform a method comprising:
filling the seal caps with sealant using an automated process, wherein
positioning the filling unit and/or positioning the seal caps by means of movement in the XYZ coordinate system as well as filling the seal caps is automated;
the seal caps are positioned on the support plate in the positioning pattern that corresponds to the positioning pattern of the connecting elements to be sealed;
the seal caps are plastic caps comprising at least one high-performance polymer selected from the group consisting of polyvinylidene fluoride (PVDF), polysulfone (PSU), polyphenylene sulfone (PPSU), polyetheretherketone (PEEK), polyimide (PI), polyamideimide (PAI), polybenzimidazole (PBI), polyetherimide (PEI), and polyphenylene sulfide (PPS), and
the sealant is a sealant based on polysulfide and/or polythioether and the plastic caps and the sealant are joined cohesively to one another.
