Abstract

PROBLEM TO BE SOLVED: To melt a function zone accurately and easily as well as to make it secure sufficient adhesive strength to a base material surface by forming a groove part run along the fusion zone being melted by an ultrasonic vibration, on a weld surface of a bracket part. SOLUTION: When a bracket part 2 is welded to a base material 1 with an ultrasonic vibration, this bracket part 2 is attached to a surface of the base material 1 after making a surface, where a groove part 4 is formed, come into contact with the surface of the base material 1, and than an ultrasonic horn 10 is applied to a fusion zone 3 from the backside of a weld surface of the bracket part 2 and it is pressurized and vibrated. If so, this vibration is transmitted to the fusion zone 3 and thereby the weld surface is gradually melted, and successively fusion resin of this fusion zone 3 is dispersed and flows into the groove part 4, whereby the weld surface of the fusion zone 3 comes to be almost flush with the fusion resin filled up in the groove part 4, therefore this fusion resin a function as an adhesive agent, through which the bracket part 2 is welded to the base material 1 as unified in a body. With this constitution, the bracket part is unifiable to the base material surface without entailing any clearance with each other.

Description of the Related Art For example, ultrasonic vibration is used as a method for mounting and integrating a surface of a base material made of a foamed synthetic resin material and a retainer mounting bracket part made of a non-foamed synthetic resin of the same type in an automobile door trim or the like. A method of welding by using is known. One of such methods is called an ultrasonic transmission welding method in which a large number of welding projections are provided on the welding surface of a bracket part, and these projections are melted by ultrasonic vibration and attached to and integrated with a base material. However, since the base made of synthetic resin foam has the property of absorbing ultrasonic vibrations, a phenomenon occurs in which the protrusions do not melt sufficiently and unbonded parts occur, resulting in sufficient adhesion. There was a problem that strength could not be obtained. There is also a method called an ultrasonic spot welding method in which an ultrasonic horn is applied to the bracket part in a spot manner, the contact surface is melted, and attached to and integrated with the base material. However, there is a problem that the foamed synthetic resin collapses, and a gap is formed on the welded surface, thereby lowering the adhesive strength. on the other hand,
There is also known a method of mechanically attaching by using a clip, a rivet, or the like without using ultrasonic vibration. However, there is a problem that an increase in the number of parts increases weight and production cost.

Further, in the conventional spot welding method, there was a phenomenon in which the resin on the base material 1 side collapses due to the heat of the molten resin, and a gap is created on the welding surface. Four
Thermal energy is also dispersed by being dispersed and flowing into the interior, and therefore, the base material 1 is made of a foamed synthetic resin, and the bracket component 2 is made of a non-foamed synthetic resin or the like that is more rigid than the base material 1. Even when used, the resin on the base material 1 side is not partially collapsed, and there is no problem that the adhesive strength is lowered due to the generation of gaps accompanying the collapse.
