【発明の詳細な説明】 ［産業上の利用分野］ 本発明はプラスチックの伝達溶着法に係り、特に捩り振

ネルギを与える方法を採っている。By the way, for example, when a tubular welding piece is ultrasonically welded to a thin plate-shaped substrate, conventionally, in order to efficiently apply ultrasonic longitudinal vibration energy to the welding surface, it is disclosed in Japanese Utility Model Laid-Open No. 61-921. As described above, a method of applying ultrasonic energy from the back side of the substrate is adopted.

ればならない等の問題がある。[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional welding method, the structure of the tool horn is complicated and it cannot be applied when the substrate is large. In this case, a special treatment is required. There is a problem that the welding piece must be held by using a tool and the substrate must be placed on the welding piece to perform ultrasonic welding.

Moreover, even if the substrate is a thin plate, if the surface on which the horn hits has irregularities or protrusions that are affected by vibration, the radiation surface of the tool horn must be processed according to the irregular shape of the substrate. However, there is a problem that processing is not easy.

ことを目的とする。The present invention has been made in view of the current situation, and without using a special jig or the like, even when the substrate is large and ultrasonic energy cannot be applied from the back side of the substrate. An object of the present invention is to provide a plastic transfer welding method capable of easily and satisfactorily welding a welding piece onto a substrate.

る。[Means for Solving the Problems] As means for achieving the above object, the present invention is such that the dimension between the input surface and the radiation surface facing the input surface resonates with a half wavelength by torsional vibration with respect to the vibration frequency used. Using the tool horn set as described above, the welding piece placed on the substrate is subjected to torsional vibration while being pressed by the tool horn, and the energy of the radiation surface is passed through the inside of the welding piece and the welding piece and the substrate. Is a plastic transfer welding method in which a welding piece is transferred to the contact surface of the substrate, and the welding piece is welded to the substrate by the contact surface. It is characterized in that a ring-shaped rib is formed.

に向上させることが可能となる。[Operation] In the plastic transmission welding method according to the present invention, the welding piece placed on the substrate is pressed by the tool horn, and torsional vibration is applied in this state. Then, the energy of the radiation surface of the tool horn is transmitted to the contact surface between the welding piece and the substrate through the inside of the welding piece, and heat is generated by rubbing on the contact surface, so that the welding piece and the substrate are welded. Therefore, the work is performed only from the side where the welding piece is welded, and the workability can be significantly improved.

It becomes possible to further stabilize the welded state.

［実施例］ 以下、本発明実施の一例を図面を参照して説明する。[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

０に溶着されるようになっている。1 and 2 show an example of an apparatus configuration for carrying out the plastic transmission welding method according to the present invention. In the drawings, reference numeral 1 is a cylindrical tool horn for torsional vibration. With this tool horn 1, the tubular welding piece 20 is pressed against the substrate 30 with the pressure P, and in this state, the ultrasonic torsional vibration F is applied, whereby the welding piece 20 is transferred to the substrate 3
It is designed to be welded to zero.

Ｌは、前記超音波捩り振動Ｆの周波数λのほぼ半分の長

る。As shown in FIG. 3, the tool horn 1 has a dimension L between the input surface 2 to which the ultrasonic torsional vibration F is applied and the radiation surface 3 in contact with the welding piece 20. The dimension L is set to about λ / 2, which is about half the frequency λ of the ultrasonic torsional vibration F, so that half-wavelength resonance occurs.

でる。Further, the L / 2 area on the radiation surface 3 side of the tool horn 1 is the third
As shown in the drawing, the diameter is reduced, and the diameter thereof is set to R / 2, which is half the diameter R on the input surface 2 side, for example.
This allows the radiation surface 3 to respond to the displacement on the input surface 2 side.
The displacement on the side can be enlarged. The displacement increase in this case is larger than that in the conventional longitudinal vibration. This is because the longitudinal vibration increases the amplitude by the reciprocal of the area ratio, while the torsional vibration increases the amplitude by the reciprocal of the radius quadratic ratio.

うになっている。On the other hand, the welding piece 20 to be welded on the substrate 30 has the first
As shown in FIG. 4, FIG. 5 and FIG. 5, on the contact surface with the substrate 30, for example, a plurality of radial small projections 20a or a ring-shaped rib 20b having an inverted triangular cross section is provided. Energy transmitted from the tool horn 1 is concentratedly applied to each of the small projections 20a or the ribs 20b so that more stable welding can be performed.

次に、本発明に係るプラスチックの伝達溶着法について
説明する。Next, the plastic transfer welding method according to the present invention will be described.

な変位を容易に得ることができる。When welding the welding piece 20 on the substrate 30, first, the welding piece 20 is placed on the substrate 30, and the welding piece 20 is pressed by the tool horn 1 with the pressure P. And in this state,
The ultrasonic torsional vibration F is applied to the input surface 2 of the tool horn 1. Then, the radiation surface 3 of the tool horn 1 is torsionally oscillated in a phase opposite to that of the input surface 2, and the displacement thereof is larger than the displacement of the input surface 2. Since the amplitude of this displacement increase is expanded by the reciprocal of the fourth power ratio of the radius, it is possible to easily obtain a larger displacement than in the case of longitudinal vibration.

このため、各小突起２０ａあるいはリブ２０ｂは短時間
で溶融し、短時間で安定した溶着状態が得られる。The energy of the radiation surface 3 is transmitted to the contact surface between the welding piece 20 and the substrate 30 through the inside of the welding piece 20, and is concentratedly applied to each small projection 20a or the rib 20b.
Therefore, the small protrusions 20a or the ribs 20b are melted in a short time, and a stable welded state can be obtained in a short time.

厚い場合であっても、極めて容易に溶着片２０を溶着す
ることができ、溶着状態も良好である。Then, the welding piece 20 can be welded to the substrate 30 only by the operation from the welding piece 20 side.
Can be welded while being fixed. Therefore, even if the substrate 30 is large, or it is impossible to work from the back side of the substrate 30, or even if the substrate 30 has a large thickness, the welding piece 20 is extremely easily welded. And the welded state is also good.

い。In the example of the embodiment described above, the tool horn 1 having a smaller diameter on the radiation surface 3 side than the input surface 2 side has been described, but a tool horn having a straight cylindrical shape may be used. Moreover, you may use the tool horn which the radiation surface 3 side makes a cylindrical shape which imitated the shape of the welding piece 20.

ことができる。Further, the welding piece 20 can be applied not only in the case of forming a cylindrical shape but also in the case of forming a square tube, and also in the case of forming a solid rod shape without being limited to a cylinder shape. Then, the tool horn also has a rectangular tube shape, a prism shape, or the like depending on the shape of the welding piece 20.
Alternatively, the shape may be such that a circular hole is provided at the center of the prism.

また、溶着片２０に設けられる小突起２０ａあるいはリ
ブ２０ｂは、その数および形状に制限はない。Further, the number and shape of the small protrusions 20a or the ribs 20b provided on the welding piece 20 are not limited.

Using a welding horn mounted on a substrate, a torsional vibration is applied while pressing the welding piece with the tool horn, and the energy of the radiation surface is
Transmitted to the contact surface between the welding piece and the substrate through the inside of the welding piece,
Since heat is generated at the contact surface to weld the welding piece to the substrate, even if the substrate is large or ultrasonic energy cannot be applied from the back side of the substrate, a special jig is used. The welding piece can be easily and satisfactorily welded to the substrate without using the above.
