Abstract

PROBLEM TO BE SOLVED: To provide a leaser welding method by which a laser head for irradiation with laser rays can be freely moved. SOLUTION: The laser rays are emitted to the joined part from the laser head 7. Then most of the laser rays are transmitted through a sheet 5 and a duct 3 and then absorbed by an instrument panel 2. Consequently, the instrument panel 2 is thermally melted and this molten part is joined to the duct 3.

There is a resin having a high laser light absorption rate, and when the resin having a high laser light absorption rate is irradiated with laser light, the resin is heated and melted. Utilizing this phenomenon, the present applicant superposes a resin that transmits laser light (has a high transmittance) and a resin that absorbs laser light (has a high absorptance). A method of joining resin members by irradiating a laser beam to a portion where the resin members are overlapped and melting a part of the resin that absorbs the laser beam has been proposed (Japanese Patent Publication No. 5-42336). In addition, this publication also proposed a method of joining resin members by heating the adhesive interposed between the resin members with a laser beam instead of heating the resin members.

いる。The above proposal is a principle, and when resin members are actually joined together, it is necessary to fix the resins so that they do not move during the irradiation of the laser beam. As this fixing method, as disclosed in Japanese Patent Application Laid-Open No. H11-348132, there is known a method in which one resin member is overlaid on another resin member and pressed with a jig from above.

ドをＮＣ制御により３次元空間で自由に移動せしめるこ
とにより、複雑形状部であっても短時間のうちに確実に
接合できることである。One of the advantages of the joining method using laser light is that the laser head for irradiating the laser light can be freely moved in a three-dimensional space by NC control, and therefore, it has a complicated shape. However, it can be surely joined in a short time.

を接合する場合にはその傾向が顕著になる。[0005] However, as described above, it is necessary to fix the resin members by some means when irradiating the laser beam. When a jig as disclosed in Japanese Patent Application Laid-Open No. 11-348132 is used, it is necessary to avoid interference with the jig when the laser head moves, and as a result, there is a restriction on the movement of the laser head. Imposed. In particular, when large resin parts or resins having complicated shapes are joined to each other, the tendency becomes remarkable.

【０００６】また、固定冶具が押さえている箇所は固定
冶具自身が邪魔することになって接合することができ

用意しなければならないなどコスト的な不利もある。[0006] In addition, the fixing jig can not be joined because the fixing jig itself disturbs the joint, and if the model is changed, a new fixing jig must be prepared. There is also a cost disadvantage.

樹脂部材と第２の樹脂部材とを接合する。In order to solve the above-mentioned problems, a laser welding method according to the present invention comprises a first resin member having a laser beam transmitting property and a second resin member absorbing a laser beam and being heated. The first resin member and the second resin member are fixed by stacking the members and covering them with a sheet having a laser beam transmitting property, and bleeding air between the sheet and the resin member. The joining portion is irradiated with laser light through the first resin member, and the joining portion is melted to join the first resin member and the second resin member.

樹脂部材を入れて減圧して固定する態様も含む。For example, a second resin member is set on a pedestal, a first resin member is stacked on the second resin member, and the first resin member is further covered with a sheet, and air is released between the sheet and the resin member. The sheet is in close contact with the cradle, and the resin members are fixed to each other by the sheet. In the present invention, it is not always necessary to use the cradle. Further, the mode of covering with a sheet in the present invention also includes a mode in which a bag is formed with a sheet, a resin member is put in the bag, and the bag is fixed under reduced pressure.

May be glass other than resin, for example, and at least one may be a member that transmits laser light.
