Abstract

PURPOSE:To adhere thermoplastic tight contact members one of which allows the transmission of laser light or members which are interposed with a laser absorptive adhesive agent and one of which has transmission without deviation and oxidation by irradiating the laser light to the above-mentioned members. CONSTITUTION:Resin materials 1, 2 which both have thermoplasticity and one of which allows the transmission of the laser light are tightly adhered by glass plates 3, 4 or members 5, 6 at least one of which has the transmittivity are tightly adhered via an adhesive agent which absorbs the laser light, for example, ferrite, etc., interposed therebetween. The laser light 10 is irradiated on the members from the material 1, 5 side to heat and join the joint surfaces 2a or the adhesive agent 7. The members are satisfactorily joined without the generation of the deviation and oxide in the joined part and the joining can be executed regardless of the joining materials. The adhesive agent 7 may not contain the ferrite, etc., if the lower plate 6 of the two plates 5, 6 has no transmittivity.

め位置ずれが生じ易いという問題がある。(Problem to be Solved by the Invention) However, according to this method, in the former case, that is, when using ultrasonic heating, frictional heat due to vibration, a hot plate, etc., the molten resin comes into contact with air and reacts. Furthermore, since the resin material is brought into close contact with the bonding position during bonding, there is a problem in that positional displacement is likely to occur.

状が拘束されるという問題がある。In the latter case, that is, when the adhesive is heated by electromagnetic induction for bonding, it is necessary to mix ferrite or the like into the adhesive in advance, which increases the cost and increases the installation cost. There is a problem in that the shape of the object to be adhered is restricted by the shape of the installed induction coil and the like.

そこで、本発明はかかる従来の問題点を解決すべく成さ

法を提供するにある。Therefore, the present invention has been made to solve these conventional problems, and its purpose is to prevent the molten part from reacting easily with oxygen, prevent positional shift during bonding, It is an object of the present invention to provide a method for bonding members, which does not require mixing ferrite into the adhesive, is low cost, and does not restrict the shape of the bonded object by an induction coil or the like.

る。After that, carbon black using a laser beam (1o) such as a YAG laser is applied as an adhesive through the glass plate (3) supporting the first member (5) and the first member (5). When the laser beam (10) is irradiated toward the contained polyethylene (7), the laser beam (10) passes through the glass plate (8) and the first member (5) and hits the surface of the polyethylene (1) (
7a), the polyethylene (7) is heated and melted to adhere the first and second members (5) and (6).

の形状が拘束されることもない。In this way, according to the present invention, members such as resin materials to be bonded are brought into close contact with each other in advance and supported, and then bonded with laser light without contact, so that no displacement of the bonded surfaces occurs. Furthermore, the contact surface does not react when exposed to oxygen, and furthermore, when an adhesive is used, there is no need to mix ferrite as in the past. Furthermore, by appropriately changing the position of the laser oscillator, etc., the shape of the object to be adhered, etc. is not restricted.

It is possible to provide a method for bonding members using a laser, which does not require mixing, is low cost, and does not have the shape of the bonded object restricted by an induction coil or the like.
