Abstract

PURPOSE:To facilitate the joining of two synthetic resin materials without the lowering of the strength thereof by a method wherein a laser light irradiates the upper one of the laminated synthetic resin materials from ahead and behind to heat and melt and a compressed gas is blown to the melt by the rear laser light to be forced into a groove formed continuously through both of the synthetic resin materials. CONSTITUTION:A YAG laser light 4a irradiated from a front irradiation nozzle 3a is accumulated as high energy at the irradiated positions of both plate members 1 and 2 in a smaller range than the laser light 4b while both the plate members 1 and 2 are heated by the energy to melt. Consequently, melts 1b and 2b are formed on both the plate members 1 and 2 separately while a groove 5 is formed continuously through both the plate members 1 and 2. The melt 2c of the plate member 2 is forced into the continuous groove 5 previously formed through both the plate members 1 and 2 by a compressed gas blown to bump against the previous melts 1b and 2b. At this point, these three melts 1b, 2b and 2c press against each other while being partially entangled together.

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.

In other words, the former physical joining method involves heating a heating element such as a metal mesh on the joint 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, the latter chemical bonding method involves interposing an adhesive such as hot melt 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.

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.

In order to achieve the above object, the structure of the method for joining different types of synthetic resin materials according to the present invention is such that when overlapping different types of synthetic resin materials and joining them, the different types of synthetic resin materials are exposed to laser light. The two synthetic resin materials are superimposed, and a laser beam is irradiated from above the upper synthetic resin material in front and back, and the front laser beam melts both synthetic resin materials to form continuous grooves. At the same time, the upper synthetic resin material is melted in a wide range using a rear laser beam, and compressed gas is blown onto the melted area to force the melted material into continuous grooves formed in both synthetic resin materials. The remelted material is made to intertwine with each other.

In addition, the wavelength of the laser used when joining dissimilar synthetic resin materials needs to be compatible with the synthetic resin materials to be joined, and a wavelength of 1.06 μm or less is best; It is impossible to melt and join different types of synthetic resin materials. In addition, 5W to 30W is suitable for the laser output.
If the output is less than 5 W, different types of synthetic resin materials cannot be melted, and if the output is more than 30 W, the different types of synthetic resin materials will evaporate or change in quality, making it impossible to join them.
