Abstract

PURPOSE:To improve the connecting strength of synthetic resin material by a method in which the recessed portion provided on the upper synthetic resin plate of the two lapped synthetic resin plates is filled with powder material, and then said powder material is heated and molten by laser ray. CONSTITUTION:When the plate members 1, 2 of synthetic resin are connected, the through hole 3 is filled with the same synthetic resin as that of the lower plate member 1. Laser ray 6 is radiated from a radiating nozzle 5 including lightfiber, whereby the powder material is heated and molten and becomes molten material 4a. The molten material covers the periphery of the through hole 3 of the plate member 2, and simultaneously melts a part f the surface of the plate member 1, thereby connecting both plates.

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、合成樹脂材料を重ね合わせ、その一

〔従来の技術〕[Conventional technology]

従来、合成樹脂材料と合成樹脂材料とを接合す

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.

料を接合する方法である。 In other words, the former physical joining method involves heating a heating element such as a metal mesh on 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 synthetic 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.

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.

る。 For the reasons described above, mechanical joining methods are often used when joining different types of synthetic resin materials. A representative example thereof will be explained using a method of joining a polypropylene resin and a styrene-acrylonitrile copolymer reinforced with glass fibers as shown in FIG.

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.

ない不具合がある。 However, in such a mechanical joining method, when heating and melting the plate member 51 made of styrene-acrylonitrile copolymer, the heating part 56 of the soldering iron 55 is brought into direct contact with the plate member 51 to melt it. , the molten material 51a in the area that contacts the heating part 56 may be deteriorated due to carbonization or the like, reducing the bonding strength of the plate members 51, 52, and the molten material 51a may be removed when pulling up the soldering iron 55 after joining. There is a problem in that the molten material 51a adheres to the heating part 56 and must be removed every time bonding is performed.

Among the overlapping synthetic resin materials, a recess is provided in the upper synthetic resin material, and the recess is used to absorb laser light. This powder is heated and heated with laser light.
By melting, the bonding strength of synthetic resin materials can be improved and the removal work of the melted material can be completely eliminated.
