（従来の技術） 樹脂部品の溶着方法として、超音波によるスポット溶着
方法は従来から知られている。(Prior Art) A spot welding method using ultrasonic waves has been conventionally known as a welding method for resin parts.

たれる。In this prior art, as shown in FIG. 5 (a), the horn 1 having ultrasonic vibration is applied to the portion where the resin parts 3 and 4 overlap each other, and pressure is applied in the direction of the arrow so that the horn tip The convex portion 2 melts the resin material while making holes in the resin material so that the resin parts adhere to each other. Fifth
Figure (b) shows a cross section of the welded portion after welding, but the resin 6 melted by the horn 1 is the resin parts 3, 4
By closely adhering to both, the adhesive strength between the resin parts is maintained.

困難である。(Problems to be Solved by the Invention) FIG. 5 (c) is an enlarged view showing a welded portion in a circle A surrounded by a dotted line in FIG. 5 (b). FIG. 4 is a sectional view thereof, but in the prior art, the welding strength is secured by the ring-shaped sectional area 10 of the molten resin. Therefore,
Since the size of the horn 1 and its tip 2 are restricted in terms of product design, it is difficult to secure a sufficient cross-sectional area for welding.

溶着強度には何等寄与していない。In the conventional method described above, as shown in FIG. 5B, the amount of molten resin equivalent to the volume of the convex portion 2 at the tip of the horn invading the resin component overflows to the horn side. The overflowed molten resin 6 does not contribute to the welding strength of the resin components 3 and 4.

強度との関係を表わしたグラフである。(Means for Solving Problems) The present inventor has found that in ultrasonic spot welding of resin parts made of the same kind of material, the welding strength is the joint cross-sectional area of the molten resin (cross-sectional area of the boundary between both parts). It was confirmed experimentally that there is a relationship. In this experiment, as shown in Fig. 4 (b), the width is 30 mm.
And a polypropylene test piece having a length of 100 mm was superposed and welded by an ultrasonic horn, and the joint cross-sectional area was changed by changing the dimension A of the ultrasonic horn.
The welding strength of the joint was measured by a tensile tester. Fourth
FIG. 1A is a graph showing the relationship between the welding strength and the dimension A of the ultrasonic horn (bonding cross-sectional area).

させ、溶着強度の向上を達成したものである。As is clear from this graph, in ultrasonic spot welding of resin parts of the same material, the welding strength has a correlation with the joint cross-sectional area of the molten resin, but in the present invention, the resin of the same material is used. In the method of spot welding the parts to each other by ultrasonic waves, a space is provided on the joint surface of both resin parts, and the tip of the ultrasonic horn penetrates the part with the space part from the surface of one of the resin parts. The resin material is melted while forming holes in the resin material until at least a part of the other resin parts, and the space section is filled with the melted resin material, thereby increasing the joint cross-sectional area of the molten resin, This is an improvement in welding strength.

以下、本発明を図面により詳細に説明する。Hereinafter, the present invention will be described in detail with reference to the drawings.

れる。To weld the resin parts 3 and 4, pressure is applied to the ultrasonic horn 1,
This is performed by melting the resin while making holes in the resin material by the convex portion 2 at the tip of the horn. In the conventional method, as shown in FIG. 5 (b), the amount of the molten resin 6 corresponding to the volume of the convex portion 2 at the tip of the horn entering the resin component overflows to the horn side. The molten resin flows into the space 5 on the joint surface and fills the space.
The volume of the space 5 is set by judging from the expected amount of resin.

The space of the joint surface of the resin component is provided by forming a recess in the portion corresponding to the joint portion of the resin component in the case of FIG. 1, but as shown in FIG. 2 and FIG. Can be formed in various ways. Second
In the case of the figure, by providing a loop-shaped convex portion 7 serving as a weir on one of the joint surfaces of the resin parts 3 and 4, a space 5
In this case, the molten resin 6'fills the space 5 as shown in FIG.
A sandwiched state is formed between them, and the welding strength is improved due to the increase in the cross-sectional area of the joint.

In this case, as shown in Fig. 3 (b), the molten resin fills the V-shaped recesses of both resin parts, increasing the joint cross-sectional area of the molten resin and adding the anchor effect. The welding strength of is further improved.
