Problems solved by technology

However, in the case of this method, there is a problem that the glass plate is contaminated by coal or gasified components of the flame retardant generated during heating and melting of the joining members, and the absorption rate of the glass plate with respect to the laser light increases. The glass plate itself is heated so that it breaks
However, when welding is carried out by laser irradiation, one or both of the members to be joined are thermally deformed, or during molding, the members to be joined are warped, and as a result, gaps are generated between the members to be joined. The case where the adhesiveness of this attraction decreases

Abstract

The invention provides a joint structure and a method of manufacturing the joint structure, and members connected with each other can be uniformly and assuredly sealed without using a glass plate. Thejoint structure comprises a light-absorbable member having at least one opening portion and a light-permeable member superposed on the light-absorbable member so as to cover the opening portion, wherein a first annular weld part is formed so as to enclose the opening portion and join the light-absorbable member and the light-permeable member, and a second dot-like weld part(s) joining the light-absorbable member and the light-permeable member is / are formed in a position adjacent to the first weld part.

Description

Technical field [0001] The present invention relates to a joined structure including a light-absorbing member and a light-transmitting member that overlap each other and are joined to each other via a welded portion formed in the boundary surface or the vicinity of the boundary surface, and a method of manufacturing the same. Background technique [0002] Previously, as a method of joining a plurality of members, there is a joining method using laser light irradiation. Among them, there has recently been attention to a laser transmission welding that performs local heating to reduce thermal damage to the product and has less influence on the appearance of the welded part. Method (Laser Transmission Welding). This bonding method is a method in which one of the bonding members uses a member that is transparent to laser light (light transmissive member), and the other uses a member that is absorbing to laser light (light absorbing member) In the state where these are superimposed a...
