  • Patent number: 11745433
    Abstract: A connection element for adhering to a component surface of a first component, such that a second component can be secured to the first component by the connection element, including a base element having an adhesive side with an adhesive surface, and a mounting structure. The base element consists of a thermoplastic with a temperature of continued use of at least 130° C., which can be poorly irradiated or cannot be irradiated with light, and has at least one irradiation region. The base element can be irradiated with light in this region in such a way that light energy penetrates the base element. The irradiation region, in cross-section, has a smaller thickness and a transmittance at least 20% with a light wavelength between 320 and 500 nm. Alternatively, the irradiation region is formed by a through-opening.

  • Publication number: 20230250841
    Abstract: A multipart socket-like glue-in retainer which is fastenable in a component opening in an adhesive manner in a component opening and which is configured in at least two parts and thus in an opening manner in radial direction due to an axial separation, so that only before a gluing-in of the glue-in retainer in a component opening, a functional insert is arrangeable in the glue-in retainer and after the gluing-in of the glue-in retainer in the component opening, the functional insert is retained inseparably in the glue-in retainer.

  • Patent number: 11073176
    Abstract: A fastening element consisting of a cage element with a nut arranged therein that is held by a fastening flange in the cage element. The cage element has a wall element which can be moved in an axial direction and shields the seat area of the cage element against the penetration of adhesive while mounting the fastening element on a component surface.

  • Patent number: 10400806
    Abstract: The connecting element for gluing onto a component surface B comprises a retaining pin having a pin section, to which a structural component can be attached. An anchor of the retaining pin is attached in a disk made of a material which can be penetrated by light such that due to the rotation-inhibiting and removal-inhibiting shape of the anchor, a reliable connection is established between the retaining pin and the disk.

  • Patent number: 9457548
    Abstract: A manual and an automatic fastening device for fastening a bonding element to a surface by means of a light-curing adhesive is disclosed. The fastening devices apply the bonding element to the surface with a specific contact pressure, before the light is irradiated onto the bonding element for curing the adhesive. As the bonding element consists of transparent material, the adhesive is cured between the fastening element and the surface.

  • Patent number: 9297398
    Abstract: The present invention comprises a jointing head 1, a robot with this jointing head 1, and a fastening method for affixing fastening elements 9 to a component surface B. The jointing head 1 comprises a gripper 30 that removes fastening elements 9 from a removal position E of a cartridge 70 by means of a pivoting movement. In addition, the jointing head 1 comprises a compensation mechanism 40 of the gripper 30 so that, when the fastening element 9 is mounted on a component surface B, the fastening element 9 is optimally arranged adjacent to a hardening source 60 such as a light source.
