【発明の詳細な説明】
本発明は超音波接着方法に関し、熱可塑性樹脂
からなる２つの物体を安定に接着するようにした
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ultrasonic bonding method for stably bonding two objects made of thermoplastic resin.
従来、熱可塑性樹脂からなる２つの物体を超音
波溶着する場合には、第１図に示すように一方の
物体１の先端に小さな突起１ａを設け、これを他
方の物体２に圧接して超音波により突起１ａを溶
融させて接着していた。 Conventionally, when two objects made of thermoplastic resin are ultrasonically welded, a small protrusion 1a is provided at the tip of one object 1, as shown in Fig. 1, and this is pressed into contact with the other object 2 to perform ultrasonic welding. The projections 1a were melted and bonded by sound waves.
ところがこの方法では、突起１ａが超音波によ
り溶融する際に、超音波振動により空気を巻きこ
み、小さな気泡の混入した接着層が形成される。
このため接着強度は混入した気泡の量により変化
し、安定した接着強度が得にくいという問題があ
つた。 However, in this method, when the projections 1a are melted by ultrasonic waves, air is drawn in by the ultrasonic vibrations, and an adhesive layer containing small air bubbles is formed.
For this reason, the adhesive strength varied depending on the amount of air bubbles mixed in, and there was a problem that stable adhesive strength was difficult to obtain.
本発明はこのような従来の問題を解決する超音
波接着方法を提供するものである。 The present invention provides an ultrasonic bonding method that solves these conventional problems.
以下本発明の一実施例を第２図〜第３図ととも

物体４には上記リブ３ａよりわずかに幅の広い溝
４ａが設けられている。 An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. As is clear from FIG. 2, the first object 3 made of thermoplastic resin is provided with a rib 3a, and the second object 4 also made of thermoplastic resin is provided with a rib 3a slightly wider than the rib 3a. A wide groove 4a is provided.

でしつかりと結合される。 When the rib 3a is inserted into the groove 4a and ultrasonic waves are applied while applying pressure in the direction of the arrow in Figure 3a, the vicinity of the tip of the rib 3a and the vicinity of the contact surface of the groove 4a generate heat and melt due to frictional heat. The heat generated at the tip softens the contact surfaces of the ribs 3a and grooves 4a by conduction. Since pressure is applied to the rib 3a, the melted portion and softened portion at the tip of the rib 3a buckle and expand as shown in FIG. 3b. Similarly, the contact surface of the groove 4a is also softened by the frictional heat, and is formed into a shape that faces the tip of the buckled and expanded rib 3a. On the other hand, part of the rib 3a and groove 4a melted by the frictional heat is pushed out during the aforementioned buckling and expansion of the rib 3a, and flows into the gap between the rib 3a and groove 4a that is not affected by heat, as shown in Fig. 3c. As shown, when the buckled and enlarged portion of the tip of the rib 3a is wrapped around and cooled and solidified, the two objects 3 and 4 are firmly joined by a groove joint.
以上のように本発明によれば、熱可塑性樹脂か

ことができる。 As described above, according to the present invention, one of two objects made of thermoplastic resin is provided with a rib, and the other object is provided with a groove that is slightly larger than the rib,
By inserting the rib into the groove and applying pressure while applying ultrasonic waves, the contact portion between the rib and the groove is heated and melted, and the melted portion at the tip of the rib is expanded, and this expanded portion is Since the molten resin on the inner surface of the groove is poured above the groove, the bonding strength between the two members can be significantly increased.
