Abstract

Current glued connections between faceplates (FP) and shells require that the glue is applied on the flat surface. The disadvantage of this procedure is for instance, that excessive glue can flow inside the shell. By opening FP and shell in service case, the excessive glue can cause damage. Additional, FPs with dark color need extra glue because UV curing is not possible (UV: Ultraviolet). At last, normal glue is not resistant against humidity.

Controlled Gluing Connection between Faceplates and Shell

Idea: Erwin Singer, DE-Erlangen; Benjamin Schmidt, DE-Erlangen

Current glued connections between faceplates (FP) and shells require that the glue is applied on the flat surface. The disadvantage of this procedure is for instance, that excessive glue can flow inside the shell. By opening FP and shell in service case, the excessive glue can cause damage. Additional, FPs with dark color need extra glue because UV curing is not possible (UV: Ultraviolet). At last, normal glue is not resistant against humidity.

Therefore, a circumferential slot on the surface of the shell is proposed which is filled up with glue during the gluing process (see Figure 1). The slots can be created automatically, e.g. by construction software. Additional, the slots are provided with several cuts so that the excessive glue flow from pressing the FP on the shell can be discharged. Thus, no glue can penetrate the inside of the shell (see Figure 2).

The main advantage of the proposed solution is that glue can be dosed and applied easy to the surface of the shell. Only one sort of glue is necessary because of the thin wall thickness. It let the UV rays through the material.
