本発明は、異種合成樹脂材料の機械的接合方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for mechanically joining dissimilar synthetic resin materials.

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.

を接合する方法である。 In other words, the former physical joining method uses a heating element such as a metal mesh to generate heat on the joining surfaces of the synthetic resin materials to melt the joining surfaces of both synthetic resin materials while applying pressure and cooling. This is a method of joining resin materials. In addition, in the latter chemical bonding method, an adhesive such as hot melt is interposed on the joint surfaces of the synthetic resin materials to be bonded, and high frequency or ultrasonic waves are applied from the surface of one synthetic resin material to heat the adhesive. - After melting, both synthetic resin materials are cooled while being pressurized, and both synthetic resin materials are joined together.

下し、両合成樹脂材料を強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, it is difficult to join the two synthetic resin materials because their melting temperatures are different and their compatibility is poor. 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 strength of the adhesive decreases depending on the material of the material, making it difficult to firmly join both synthetic resin materials.

が接合される。 In FIG. 2, reference numeral 51 is a plate member made of styrene-acrylonitrile copolymer, and a plate member 52 made of polypropylene resin is disposed on the upper part of this plate member 51, and a step is formed in the center of the plate member 52. A through hole 53 is formed, and the thin wall portion 5
4 is formed to have a thickness of 0.5 mm to 3 mm.
When joining both plate members 51 and 52,
A heating section 56 provided at the tip of the soldering iron 55
is heated at about 20W, and the heated portion 56 is inserted into the through hole 5 of the plate member 52 made of polypropylene resin.
3, and while pressing it against a plate member 51 made of styrene-acrylonitrile copolymer, its surface is melted. At that time, the melt 5 of the plate member 51
As the heating portion 56 of the soldering iron 55 is inserted, the melt 1a rises upward from the gap in the through hole 53, and the thin wall portion 54 of the through hole 53 is covered with the molten material 51a. After the thin wall portion 54 is sufficiently covered with the melt 51a, the heating portion 56 of the soldering iron 55 is pulled up from the plate member 51. As a result, the molten material 51a hardens and both plate members 51, 52
are joined.

Not only does the molten material 51a adhere to the heating section 56 when the material is pulled up, but also there is a problem in that the molten material 51a must be removed every time joining is performed.

る。 Then, the YAG laser beam that reached the plate member 1 is
As well as being stored as energy in that part,
The surface of the plate member 1 is quickly heated and melted by the energy. After the plate member 1 is sufficiently melted by the YAG laser beam, the irradiation of the YAG laser beam is stopped, and the probe 6 is inserted through the through hole 3 as shown in FIG. Press onto the molten part. At this time, as the probe 6 is inserted, the molten material 1a of the plate member 1 rises upward from the gap in the through hole 3, and the thin wall portion 4 of the through hole 3 is covered with the molten material 1a.

is pulled up and its tip is positioned above the plate member 2 made of polypropylene resin. At this time, since the probe 6 is formed in a cylindrical shape from a polypropylene resin having a crystal structure, it is extremely difficult to bond with other substances, and can be easily pulled up without any attachment of the molten material 1a.
