Abstract
A system and a method for joining non-transparent parts (1, 2) by means of an electromagnetic radiation curable adhesive comprises at least one at least partly transparent element (3) inserted between the parts (1, 2) to be joined together such that electromagnetic radiation beamed into the element (3) initiates curing of a film of adhesive applied to the element (3) and/or to a non-transparent part (1, 2).
Claims18
A system for joining non-transparent parts by means of an electromagnetic radiation curable adhesive, comprising:
- a first non-transparent part (1);
- a second non-transparent part (2);
- a radiation curable adhesive disposed between said first and second parts;
- and
- at least one at least partly transparent element (3) disposed between said first and second non-transparent parts, said element (3) configured such that electromagnetic radiation beamed into said element (3) initiates curing of said adhesive,
- wherein said element (3) is substantially planar with opposite surfaces facing said first and second parts, and is configured and arranged between said first and second parts to only receive electromagnetic radiation beamed sideways into said element relative to said opposite surfaces,
- wherein said opposite surfaces are plano-parallel surfaces and said adhesive is applied between said opposite surfaces and corresponding non-transparent parts (1, 2).
A method for joining non-transparent parts (1, 2) by means of an electromagnetic radiation curable adhesive, comprising the steps of:
- inserting an at least partly transparent element (3) between the two parts (1, 2) to be joined together, the element including opposite substantially planar surfaces facing the two parts;
- applying a film of adhesive only between the element and each of the two parts;
- and
- curing the film of adhesive to join the parts (1, 2) with only the electromagnetic radiation that is beamed sideways relative to the opposite surfaces into the at least partly transparent element (3).
