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.

First claim

The invention claimed is:

1. A manual fastening method for a bonding element realized by means of a manual fastening device having a positioning device and a light source wherein the method comprises the following steps:
a) releasably receiving the bonding element in a holder of the manual fastening device wherein the positioning device is first moved in an installation position releasing the holder,
b) positioning the bonding element over a surface by the positioning device of the manual fastening device being displaced into a preparation position in which the positioning device radially surrounds the holder and the bonding element fastened thereto, and positioning the positioning device onto the surface so that the bonding element is brought into a mounting position based on interaction with the surface,
c) mounting the bonding element on the surface, and
d) securing the bonding element to the surface as a result of light radiation, wherein a light source radiates light in a mounting direction of the bonding element while the positioning device acts as lateral light protection and prevents a radial emergence of light.

2. The fastening method according to claim 1 , further comprising the step of:
moving the positioning device between the installation position, in which the bonding element may be installed in the holder, and the preparation position, in which the positioning device is prepared for mounting onto the surface.

3. The fastening method according to claim 1 , further comprising the step of:
signaling by means of a signal as soon as the positioning device is in the mounting position.

4. The fastening method according to claim 3 , in which the signal is one of a light signal or an audio signal.

5. The fastening method according to claim 1 , further comprising the step of:
shielding the light source by the positioning device and moving the positioning device parallel to a mounting direction of the bonding element towards the surfaces in order to detect and signal when the mounting position is reached.

6. The fastening method according to claim 5 , in which when the mounting position is reached a signal is produced, which signals when the mounting position is reached.

7. The fastening method according to claim 1 , further comprising the step of:
applying an adhesive onto the bonding element before or after receiving the bonding element in the holder.

8. The fastening method according to claim 7 , in which the adhesive is a light curing adhesive.

9. A manual fastening method for a bonding element realized by means of a manual fastening device having a positioning device and a light source wherein the method comprises the following steps:
a) releasably receiving the bonding element in a holder of the manual fastening device wherein the positioning device is first moved in an installation position releasing the holder,
b) positioning the bonding element over a surface by the positioning device of the manual fastening device being displaced into a preparation position in which the positioning device radially surrounds the holder and the bonding element fastened thereto, and positioning the positioning device onto the surface so that the bonding element is brought into a mounting position based on interaction with the surface, wherein sensors disposed on the positioning device surface are configured to detect when a desired positioning of the fastening device relative to the surface has been reached and, upon determining the desired positioning is reached communicating to a user the reaching of the desired positioning,
c) mounting the bonding element on the surface, and
d) securing the bonding element to the surface as a result of light radiation.

10. The fastening method according to claim 9 , further comprising the step of:
moving the positioning device between the installation position, in which the bonding element may be installed in the holder, and the preparation position, in which the positioning device is prepared for mounting onto the surface.

11. The fastening method according to claim 9 , further comprising the step of:
signaling by means of a signal as soon as the positioning device is in the mounting position.

12. The fastening method according to claim 11 , in which the signal is one of a light signal or an audio signal.

13. The fastening method according to claim 9 , further comprising the step of:
shielding the light source by the positioning device and moving the positioning device parallel to a mounting direction of the bonding element towards the surfaces in order to detect and signal when the mounting position is reached.

14. The fastening method according to claim 9 , further comprising the step of:
applying an adhesive onto the bonding element before or after receiving the bonding element in the holder.

15. The fastening method according to claim 14 , in which the adhesive is a light curing adhesive.

16. An automatic fastening method for a bonding element, by means of an automatic fastening device having a linearly movable or pivotable holder for loading the bonding element from at least one magazine on the fastening device, wherein the method which comprises the following steps:
a) automatically providing a plurality of said bonding elements with light-curing adhesive, and moving the plurality of said bonding elements provided with the adhesive into the at least one magazine,
b) releasably receiving the bonding element from a magazine in a holder of the automatic fastening device based on at least one of a linear or pivoting movement of the holder or a linear or pivoting movement of the magazine movably mounted to the automatic fastening device,
c) mounting the bonding element onto a surface, and
d) irradiating the bonding element with light by means of a plurality of LEDs in order to cure adhesive by exposure to light when a desired positioning of the fastening device relative to the surface has been reached and, upon determining the desired positioning is reached, adapted to communicate to the holder to mount the bonding element to the surface and communicate to the light source to radiate light so that the adhesive located on the bonding element fastens the bonding element to the surface.

17. The fastening method according to claim 16 , further comprising the step of:
pivoting the holder from a mounting direction into a removal position perpendicular to the mounting direction adjacent to the magazine.

18. The fastening method according to claim 16 , further comprising the step of:
moving the magazine arranged parallel to the mounting direction, between a resting position and a loading position perpendicular to the mounting direction so that during the mounting of the bonding element the fastening device has a smaller interfering contour than when loading the bonding element in the holder.

19. An automatic fastening method for a bonding element by means of an automatic fastening device having a linearly movable or pivotable holder for loading the bonding element from at least one magazine on the fastening device wherein the method which comprises the following steps:
a) automatically providing a plurality of said bonding elements with light-curing adhesive, and moving the plurality of said bonding elements provided with the adhesive into the at least one magazine,
b) releasably receiving the bonding element from a magazine in a holder of the automatic fastening device based on at least one of a linear or pivoting movement of the holder or a linear or pivoting movement of the magazi
