Abstract

PURPOSE:To facilitate the joining of two synthetic resin materials with the lowering of the strength thereof by a method wherein a laser irradiates both of the laminated synthetic resin materials to heat and melt separately and compressed gases blown to melted portions thereof to press both of the melts to entangle together. CONSTITUTION:YAG laser lights 5a and 5b are accumulated as energy at irradiated positions of both plate members 1 and 2 to heat and melt the intended portions thereof 1 and 2 while melts 1c and 2c are formed on both the plate members 1 and 2 separately. The melt 2c of the plate member 2 forms a concave 2d by a blowing pressure of a compressed gas while the melt 2c corresponding to the amount thereof forming the concave 2d heaps toward the tip 2b of the plate member 1. The melt 1c corresponding to the amount thereof forming the concave 1d heaps to the tip 2b thereof to bump against the sagged melt 2c of the plate member 2. At this point, both the melts 1c and 2c press against each other to be partially entangled.

。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method of superimposing different types of synthetic resin materials and bonding them together using a laser beam.

〔従来技術〕[Prior art]

従来、合成樹脂材料と合成樹脂材料とを接合する際には
、熱を加えて溶着する物理的接合方法と接着剤を用いて
接着する化学的接合方法が広く利用されている。Conventionally, when joining synthetic resin materials, a physical joining method in which heat is applied to weld them, and a chemical joining method in which they are joined together using an adhesive have been widely used.

法である。In other words, the former physical joining method uses a heating element such as a metal mesh to generate heat at the joining surfaces of the synthetic resin materials to be joined, melting the joining surfaces of both synthetic resin materials, and pressurizing and cooling them. This is a method of joining resin materials. In addition, the latter chemical bonding method involves interposing an adhesive such as Honmelt on the bonding surfaces of the synthetic resin materials to be bonded.
In this method, high frequency or ultrasonic waves are applied to the surface of one synthetic resin material to heat and melt the adhesive, and then both synthetic resin materials are cooled while being pressurized to join both synthetic resin materials.

固に接合することは困難である。However, in the former physical joining method, when joining synthetic resin materials of the same type, both synthetic resin materials have the same melting temperature and are compatible, so both synthetic resin materials are However, when joining different types of synthetic resin materials, the melting temperatures of the two synthetic resin materials are different and the compatibility is poor.
It is difficult to join both synthetic resin materials. In addition, the latter chemical bonding method is as suitable as the former physical bonding method when bonding synthetic resin materials of the same type, but it is suitable for bonding synthetic resin materials of different types. The adhesive force of the adhesive decreases depending on the material of the material, making it difficult to firmly join both synthetic resin materials.

表例を第３図に示すポリプロピレンとポリエチレンの接
合方法によって説明する。For the reasons described above, mechanical joining methods are often used when joining different types of synthetic resin materials. A typical example thereof will be explained using a method of joining polypropylene and polyethylene shown in FIG.

．． There is a problem that the strength of 52 is reduced.

法を提供することにある。The present invention has been made to solve the above-mentioned problems, and its purpose is to irradiate laser light to each of the two synthetic resin materials of the superimposed synthetic resin materials to heat and melt them. By spraying compressed gas onto each of the melted parts of the material to press the two melted materials together and entangle them, the strength of both synthetic resin materials is maintained.
It is an object of the present invention to provide a method for joining dissimilar synthetic resin materials that can be easily joined.

After overlapping both synthetic resin materials with a step, the surfaces of both synthetic resin materials are irradiated with laser light to melt them, and compressed gas is applied to each of the melted parts. The two melts are pressed against each other and intertwined.
