Description

本発明は、超音波振動によって発生した摩擦熱を利用してワークと被溶着物とを溶着する超音波溶着機に係り、特にハンディータイプの超音波溶着機においてワークとホーンが滑ることなく作業が行えるようにした超音波溶着機に関する。   The present invention relates to an ultrasonic welding machine that welds a workpiece and an object to be welded using frictional heat generated by ultrasonic vibration, and in particular, in a handy type ultrasonic welding machine, the work and the horn can be operated without slipping. The present invention relates to an ultrasonic welding machine that can be used.

ハンディータイプの超音波溶着機を使用して超音波溶着作業を行う場合には、ホーンがワークに対して滑ってしまうという問題があった。そこで、下記の特許文献１や図８に示すような昇降式の固定治具１０１が使用されていた。この昇降式の固定治具１０１は、基台１０３と、基台１０３から垂直に立ち上げられている支柱１０５と、超音波溶着機１０７を上記支柱１０５に沿って昇降移動させるための昇降機構１０９とを備えている。このような構成であれば、ホーン１１１のワークに対する位置を決めることが可能となり、ホーン１１１のワークに対する滑りを防止することができ、作業の熟練を要することなく、誰でも簡単に確実な超音波溶着作業が実行できるようになる。   When performing ultrasonic welding using a handy type ultrasonic welding machine, there is a problem that the horn slides on the workpiece. Therefore, an elevating type fixing jig 101 as shown in the following Patent Document 1 and FIG. 8 has been used. The elevating type fixing jig 101 includes a base 103, a support column 105 standing upright from the base 103, and an elevating mechanism 109 for moving the ultrasonic welding machine 107 up and down along the support column 105. And. With such a configuration, it becomes possible to determine the position of the horn 111 with respect to the work, prevent slipping of the horn 111 with respect to the work, and anyone can easily and reliably perform ultrasonic waves without requiring skill in work. Welding work can be executed.

又、上記のような構成の固定治具１０１を使用しない場合には、ホーン１１１の先端部１１３の先端面１１５に工夫を施すようにしていた。例えば、ワークの接合部がカシメ溶着用のボスのように突起した形状であれば、ホーン１１１の先端部１１３の端面１１５に凹みを設けたり、或いはワークの接合部が平面形状であれば、図９に示すように、超音波溶着機１０７のホーン１１１における先端部１１３の端面１１５に対して滑り止め用のローレット加工などを施すようにしていた。このように構成すればホーン１１１のワークに対する滑りを防止することができる。   Further, when the fixing jig 101 having the above-described configuration is not used, the tip surface 115 of the tip portion 113 of the horn 111 is devised. For example, if the workpiece joint has a shape that protrudes like a boss for caulking and welding, a dent is provided on the end surface 115 of the tip 113 of the horn 111, or if the workpiece joint has a planar shape, As shown in FIG. 9, knurling for preventing slipping or the like is performed on the end surface 115 of the tip 113 of the horn 111 of the ultrasonic welder 107. If comprised in this way, the slip of the horn 111 with respect to the workpiece | work can be prevented.

特開２００５−５３０６３号公報Japanese Patent Laying-Open No. 2005-53063

上記従来の構成によると次のような問題があった。即ち、昇降式の固定治具１０１を使用する場合には、ホーン１１１をワークに対して位置決めすることはできるものの、昇降式の固定治具１０１は高額であり、工場等において超音波溶着作業を行っているすべての作業者に対して昇降式の固定治具１０１を揃えるとなると、そのための設備コストは多額に及んでしまう。
又、ワークの接合部の形状や大きさに合わせて、いちいちホーン１１１における先端部１１３の端面１１５の形状を変えることは極めて煩雑であるし、上記凹み加工やローレット加工を頻繁に行うことになると、その加工コストも相当な額になる。又、上記凹みやローレット加工は使用に伴って当然摩耗するため、そのための修理やホーン１１１の交換に要する消耗品コストも当然必要になってくる。 The conventional configuration has the following problems. That is, when using the lifting fixture 101, the horn 111 can be positioned with respect to the workpiece, but the lifting fixture 101 is expensive, and ultrasonic welding work is required at factories and the like. If the lifting fixtures 101 are arranged for all workers, the equipment cost for that is large.
In addition, it is extremely complicated to change the shape of the end surface 115 of the tip 113 of the horn 111 in accordance with the shape and size of the joint portion of the workpiece, and the dent processing and the knurling processing are frequently performed. The processing cost is also considerable. In addition, since the dent and knurling are naturally worn with use, the cost of consumables required for repair and replacement of the horn 111 is naturally required.

本発明はこのような点に基づいてなされたものでその目的とするところは、ワークと被溶着物のセット位置やセット角度を作業がやり易いように自由に変更でき、種々の大きさや形状のワークと被溶着物及びワークの接合部に対して適用でき、ワークとホーンの滑りが生じない構造が簡単で安価な超音波溶着機を提供することにある。   The present invention has been made on the basis of the above points. The object of the present invention is to freely change the set position and set angle of the workpiece and the welded object so that the work can be easily performed. An object of the present invention is to provide an ultrasonic welding machine that can be applied to a workpiece, a workpiece to be welded, and a workpiece joint, and has a simple and inexpensive structure in which the workpiece and the horn do not slip.

又、ゴム状弾性体としてシリコーンチューブを使用した場合には上記耐熱性に加えて、適度な硬さと弾性力が得られるため、超音波溶着によってワークの接合部が溶けて形状を変化させても、シリコーンチューブの弾性変形によって上記ワークの接合部の形状変化に対応でき、シリコーンチューブの剛性によって超音波溶着機のホーンを安定した状態で支持することが可能になる。
又、ゴム状弾性体の内径をゴム状弾性体の自重によってホーンの先端部からゴム状弾性体が外れることがなく、且つホーンの先端部との過剰な密着によって超音波振動による摩擦熱が高まってゴム状弾性体が損傷を受けることがない大きさに設定した場合には、超音波溶着機の作業性を損なうことなく、ゴム状弾性体の寿命を延ばすことができる。
又、ゴム状弾性体の長さをホーンの先端部の長さより長く、溶着後のワークの接合部の高さを考慮した長さに設定した場合には、ワークの接合部に対して最初に作用するのはゴム状弾性体であり、ゴム状弾性体の有する弾性力によって衝突時の衝撃が緩和される他、溶着後も引き続き、ワークの接合部に対するゴム状弾性体の係止状態が維持される。
又、上記位置決め手段は上記ホーンの外周部に取り付けられるフロントケースと、上記フロントケース内を摺動するスライドケースと、上記フロントケース内に縮設され、上記スライドケースを突出方向に付勢する付勢手段とを具備しており、上記スライドケースは上部に上記ホーンの先端部の端面に当接するフランジ部を有し、下部に直接、ワークの接合部に作用して位置決め作用をするスリーブを有しており、上記ホーンが超音波振動して上記ワークが溶け込むことと連動して、上記スライドケースの先端部は上記付勢手段の付勢力に抗して上記フロントケース内部に収容されていくように構成されているので、例えば、ボスの溶接作業に適している。
又、上記スライドケースの先端部内周面をは先端に向かって徐々に拡大されるようにテーパ状に形成した場合には、溶融したワークの一部が広がり易いという利点がある。 As described above in detail, according to the ultrasonic welding machine of the present invention, it is possible to improve the workability of the ultrasonic welding work by reliably preventing the horn and the workpiece from slipping, and to improve the accuracy of the ultrasonic welding. be able to.
In addition, when the positioning member is formed of a cylindrical rubber-like elastic body having heat resistance that does not melt at the melting point of the workpiece, the positioning member can be configured with a very simple configuration, and the tip of the cylindrical rubber-like elastic body If the workpiece joint has a projection shape, it is held by its inner wall surface. If the workpiece joint has a planar shape, the position of the horn in the left and right and front and rear directions is determined by the frictional resistance of the rubber-like elastic body. Misalignment is prevented. Further, due to the heat resistance of the rubber-like elastic body, the rubber-like elastic body does not undergo thermal deformation or the like even if the joint portion of the workpiece is melted.
Also, when a silicone tube is used as the rubbery elastic body, in addition to the above heat resistance, moderate hardness and elastic force can be obtained, so even if the joint part of the workpiece is melted by ultrasonic welding and the shape is changed. The shape of the joint portion of the workpiece can be accommodated by elastic deformation of the silicone tube, and the horn of the ultrasonic welder can be stably supported by the rigidity of the silicone tube.
In addition, the rubber-like elastic body has an inner diameter that prevents the rubber-like elastic body from coming off the tip of the horn due to its own weight, and frictional heat due to ultrasonic vibration increases due to excessive contact with the tip of the horn. When the size is set such that the rubber-like elastic body is not damaged, the life of the rubber-like elastic body can be extended without impairing the workability of the ultrasonic welding machine.
Also, if the length of the rubber-like elastic body is longer than the length of the tip of the horn and is set in consideration of the height of the workpiece joint after welding, The rubber-like elastic body acts on the rubber-like elastic body. The elastic force of the rubber-like elastic body alleviates the impact at the time of collision, and the state of the rubber-like elastic body locked to the workpiece joint is maintained after welding. Is done.
The positioning means includes a front case attached to the outer periphery of the horn, a slide case that slides within the front case, and a contraction member that is contracted within the front case and biases the slide case in the protruding direction. The slide case has a flange portion that comes into contact with the end face of the tip of the horn at the top, and a sleeve that acts directly on the joint portion of the workpiece to perform positioning. The tip of the slide case is accommodated inside the front case against the biasing force of the biasing means in conjunction with the sonic vibration of the horn and the melting of the workpiece. For example, it is suitable for boss welding work.
Further, when the inner peripheral surface of the tip end portion of the slide case is formed in a tapered shape so as to be gradually enlarged toward the tip end, there is an advantage that a part of the melted workpiece is easily spread.

（１）第１の実施の形態（図１〜図３参照）
図１は第１の実施の形態に係る超音波溶着機を一部分解して示す側面図、図２は同上の使用状態を示す側面図である。図３は超音波溶着前のワークと被溶着物を示す側面図（ａ）と、超音波溶着後のワークと被溶着物を示す側面図（ｂ）である。 Hereinafter, the first embodiment of the ultrasonic welder of the present invention shown in FIGS. 1 to 3, the second embodiment of the ultrasonic welder of the present invention shown in FIGS. 4 and 5, and FIG. The third embodiment of the ultrasonic welder of the present invention shown in FIG. 4 and the fourth embodiment of the ultrasonic welder of the present invention shown in FIG. Will be explained.
(1) 1st Embodiment (refer FIGS. 1-3)
FIG. 1 is a partially exploded side view showing the ultrasonic welding machine according to the first embodiment, and FIG. 2 is a side view showing a use state of the above. FIG. 3 is a side view (a) showing the workpiece and the workpiece to be welded before ultrasonic welding, and a side view (b) showing the workpiece and the workpiece to be welded after ultrasonic welding.

本実施の形態では図３（ａ）に示すように接合部１に突起形状のボス３が形成されている合成樹脂製のワークＷと、穴５が形成されている被溶着物Ａとを超音波溶着し、図３（ｂ）に示すようなカシメ溶着を行う場合に使用できる超音波溶着機１１を示している。
尚、図３（ａ）中、φＢは超音波溶着前のボス３の直径、ＬＢは被溶着物Ａの表面から突出している超音波溶着前のボス３の出しろ高さである。又、図３中、φＢＷは超音波溶着後のボス３の溶着痕の直径、ＬＢＷは被溶着物Ａの表面から突出している超音波溶着後のボス３の溶着痕の出しろ高さである。
この超音波溶着機１１は手で持って超音波溶着作業を行うことができるハンドピースタイプの超音波溶着機である、そして超音波溶着機１１は超音波振動を発生させる超音波発振器１３と、発生した超音波振動を増幅させるホーン１５と、ホーン１５の先端部１７に取り付けられる位置決め部材１９とを基本的に備えることによって構成されている。
又、上記超音波発振器１３と、超音波発振器１３を駆動するための図示しない駆動装置や電気配線等がケース２１内に収容されており、ケース２１の表面には超音波発振器１３の起動と停止を切り替える切替えスイッチ２３が設けられている。 In this embodiment, as shown in FIG. 3 (a), the workpiece W made of synthetic resin in which the projection-shaped boss 3 is formed in the joint portion 1 and the workpiece A in which the hole 5 is formed are superposed. The ultrasonic welding machine 11 which can be used when performing ultrasonic welding and caulking welding as shown in FIG.3 (b) is shown.
In FIG. 3 (a), φ B is the diameter of the boss 3 before ultrasonic welding, L B is out Ro height of the boss 3 before ultrasonic welding, which protrude from the surface of the weld deposit A. In FIG. 3, φ BW is the diameter of the welding mark of the boss 3 after ultrasonic welding, and L BW is the height of the welding mark of the boss 3 after ultrasonic welding protruding from the surface of the object A to be welded. It is.
This ultrasonic welding machine 11 is a hand piece type ultrasonic welding machine that can be held by hand to perform ultrasonic welding work, and the ultrasonic welding machine 11 includes an ultrasonic oscillator 13 that generates ultrasonic vibrations, The horn 15 for amplifying the generated ultrasonic vibration and the positioning member 19 attached to the tip 17 of the horn 15 are basically provided.
The ultrasonic oscillator 13 and a driving device (not shown) for driving the ultrasonic oscillator 13 and electrical wiring are accommodated in the case 21, and the ultrasonic oscillator 13 is started and stopped on the surface of the case 21. A changeover switch 23 for switching between the two is provided.

尚、超音波発振器１３とホーン１５の構成については既存のハンドピースタイプの超音波溶着機における超音波発振器とホーンの構成と同様であるので詳細な説明は省略する。
ホーン１５の外形形状は図１に示すように基部２５が太く、先端部１７が細い径違い丸棒状の形状を有している。又、上記基部２５と先端部１７との間には逆円錐台形状のテーパ部２７が形成されている。
尚、先端部１７の直径をφＨ、長さをＬＨとする。 The configurations of the ultrasonic oscillator 13 and the horn 15 are the same as the configurations of the ultrasonic oscillator and the horn in the existing handpiece type ultrasonic welding machine, and thus detailed description thereof is omitted.
As shown in FIG. 1, the outer shape of the horn 15 has a round bar shape in which the base portion 25 is thick and the distal end portion 17 is thin. Further, a tapered portion 27 having an inverted frustoconical shape is formed between the base portion 25 and the distal end portion 17.
The diameter of the tip 17 is φ H and the length is L H.

位置決め部材１９はワークＷの融点では溶けない耐熱性と、適度な硬さと、上記ワークＷの接合部１の形状変化に対応できる弾力性とを有し、ワークＷの表面７に当接した時に滑りが生じない程度の摩擦力を発揮し得る筒状のゴム状弾性体２９によって形成されている。
尚、ゴム状弾性体２９としてはシリコーンチューブが一例として使用でき、ゴム状弾性体２９のチューブ内径をφＴ、チューブ長さをＬＴとすると、上記ホーン１５の先端部１７の直径φＨと長さＬＨとの間に以下のような関係が好適な条件として導き出される。 The positioning member 19 has heat resistance that does not melt at the melting point of the workpiece W, moderate hardness, and elasticity that can cope with the shape change of the joint portion 1 of the workpiece W. It is formed by a cylindrical rubber-like elastic body 29 that can exhibit a frictional force that does not cause slipping.
As the rubber-like elastic body 29 can be used as an example silicone tube, when the tube inner diameter phi T of the rubber-like elastic body 29, the tube length and L T, and the diameter phi H of the tip 17 of the horn 15 following such relationship between the length L H is derived as suitable conditions.

まず、ゴム状弾性体２９のチューブ内径φＴはゴム状弾性体２９の自重でホーン１５の先端部１７からゴム状弾性体２９が外れてしまわない程度の大きさに設定されている。又、ホーン１５の先端部１７の直径φＨとゴム状弾性体２９のチューブ内径φＴとの間にはφＨがφＴに比べて大きくなり過ぎないよう、好ましくはφＴ＝φＨ±０．５ｍｍの範囲内に収まるように設定されている。因みにこのように設定することによってゴム状弾性体２９がホーン１５の先端部１７に過剰に密着することによって生ずる超音波振動による摩擦熱が低くなり、当該摩擦熱が大きい場合に発生するゴム状弾性体２９の熱変形や焼け等の損傷が未然に防止される。 First, Bore phi T of the rubber-like elastic body 29 is set to a size that does Shimawa off the rubber-like elastic material 29 from the tip 17 of the horn 15 by the weight of the rubber-like elastic body 29. Also, to avoid too large compared to the phi H is phi T between the tube inner diameter phi T of diameter phi H and the rubber-like elastic body 29 of the tip 17 of the horn 15, preferably φ T = φ H ± It is set to be within a range of 0.5 mm. Incidentally, by setting in this way, the frictional heat due to the ultrasonic vibration generated when the rubber-like elastic body 29 is excessively adhered to the tip portion 17 of the horn 15 is reduced, and the rubber-like elasticity generated when the frictional heat is large. Damage such as thermal deformation and burning of the body 29 is prevented in advance.

又、ゴム状弾性体２９のチューブ内径φＴはボス３の直径φＢより大きい方が好ましいが、大き過ぎるとホーン１５の振れが生ずるため、ゴム状弾性体２９のチューブ内径φＴは超音波溶着後のボス３の溶着痕の直径φＢＷ程度に設定する。
又、ゴム状弾性体２９のチューブ長さＬＴはホーン１５の先端部１７の長さＬＨより長くなるように設定する。具体的にはゴム状弾性体２９のチューブ長さＬＴはホーン１５の先端部１７の長さＬＨに超音波溶着後のボス３の溶着痕の出しろ高さＬＢＷを加えた長さに設定することが好ましい。因みにこのような長さに設定することによって超音波溶着後もゴム状弾性体２９とボス３との係止状態が維持されるから、ゴム状弾性体２９がボス３から外れてしまう事態が防止される。 Although Bore phi T of the rubber-like elastic material 29 it is preferably greater than the diameter phi B of the boss 3, since too large deflection of the horn 15 is produced, Bore phi T of the rubber-like elastic body 29 is ultrasound The diameter of the welding mark of the boss 3 after welding is set to about φBW .
Also, tube length L T of the rubber-like elastic body 29 is set to be longer than the length L H of the tip 17 of the horn 15. Tube length L T is the length obtained by adding the height L BW Ro out of the welding mark boss 3 after ultrasonic welding the length L H of the tip 17 of the horn 15 of the specific rubber-like elastic material 29 It is preferable to set to. Incidentally, by setting such a length, the state where the rubber-like elastic body 29 and the boss 3 are locked is maintained even after the ultrasonic welding, so that the situation where the rubber-like elastic body 29 is detached from the boss 3 is prevented. Is done.

そしてこのような構成の超音波溶着機１１を使用して図３に示すようなボス３を有するワークＷと穴５を有する被溶着物Ａを超音波溶着する場合には、以下のような作業手順で超音波溶着を実行する。まず、図３（ａ）に示すようにワークＷの接合部１に形成されているボス３を被溶着物Ａの穴５に挿し込んだ状態にする。
一方、ホーン１５の先端部１７には図２に示すようにゴム状弾性体２９を外側から嵌め込んでおき、ホーン１５の先端部１７の端面３１から下方に突出しているゴム状弾性体２９の内方空間３３をボス３を係止する係止凹部として利用し、図２に示すように超音波溶着機１１をセットする。 When the workpiece W having the boss 3 as shown in FIG. 3 and the workpiece A having the hole 5 are ultrasonically welded using the ultrasonic welder 11 having such a configuration, the following operations are performed. Perform ultrasonic welding in the procedure. First, as shown in FIG. 3A, the boss 3 formed at the joint 1 of the workpiece W is inserted into the hole 5 of the workpiece A.
On the other hand, a rubber-like elastic body 29 is fitted into the front end portion 17 of the horn 15 from the outside as shown in FIG. 2, and the rubber-like elastic body 29 protruding downward from the end surface 31 of the front end portion 17 of the horn 15. Using the inner space 33 as a locking recess for locking the boss 3, the ultrasonic welding machine 11 is set as shown in FIG.

この状態で切替えスイッチ２３を押すと、超音波発振器１３から超音波振動が発せられ、ホーン１５によって増幅された超音波振動がボス３に伝わって摩擦熱を発生させ、ボス３を溶融させる。そしてその状態でボス３を硬化させれば図３（ｂ）に示すようなボス３の溶着痕が形成され、ワークＷと被溶着物Ａのカシメ溶着加工が完了する。
このような構成の超音波溶着機１１によると、極めて簡単な構成で位置決め部材１９を構成でき、筒状のゴム状弾性体２９の先端部の内方空間３３内にボス３を収容するだけで当該ボス３を保持することができる。又、ゴム状弾性体２９の内方空間３３とボス３との係止状態は超音波溶着開始前のセット時から超音波溶着完了時までの間、持続されるから作業中のワークＷとホーン１５間の位置ずれは生じない。 When the changeover switch 23 is pressed in this state, ultrasonic vibration is emitted from the ultrasonic oscillator 13, and the ultrasonic vibration amplified by the horn 15 is transmitted to the boss 3 to generate frictional heat, thereby melting the boss 3. If the boss 3 is cured in this state, a welding mark of the boss 3 as shown in FIG. 3B is formed, and the crimping welding process between the workpiece W and the workpiece A is completed.
According to the ultrasonic welder 11 having such a configuration, the positioning member 19 can be configured with a very simple configuration, and the boss 3 is simply accommodated in the inner space 33 at the tip of the cylindrical rubber-like elastic body 29. The boss 3 can be held. In addition, the locked state between the inner space 33 of the rubber-like elastic body 29 and the boss 3 is maintained from the set time before the start of the ultrasonic welding until the completion of the ultrasonic welding, so the work W and the horn that are being worked on. No misalignment between 15 occurs.

又、ゴム状弾性体２９の有する耐熱性によってワークＷの接合部１が溶融してもゴム状弾性体２９の熱変形等は生じない。またゴム状弾性体２９としてシリコーンチューブを使用したことにより、適度な硬さと弾性力が得られるため、ワークＷの接合部１の溶着後の形状変化にも対応でき、ホーン１５の作業中の姿勢の安定性も保たれる。
そして作業性が良く、種々の大きさや形状のワークＷ、被溶着物Ａ及びワークＷの接合部１に対して適用することができ、しかも構造が簡単で安価な超音波溶着機１１を提供することが可能になる。 Further, due to the heat resistance of the rubber-like elastic body 29, even if the joining portion 1 of the workpiece W is melted, the rubber-like elastic body 29 is not thermally deformed. Moreover, since a moderate hardness and elastic force can be obtained by using a silicone tube as the rubber-like elastic body 29, it is possible to cope with a shape change after welding of the joint 1 of the workpiece W, and the posture of the horn 15 during operation. Stability is also maintained.
An ultrasonic welding machine 11 is provided that has good workability, can be applied to the workpiece W of various sizes and shapes, the workpiece A, and the joint 1 of the workpiece W, and has a simple structure and is inexpensive. It becomes possible.

（２）第２の実施の形態（図４、図５参照）
図４は第２の実施の形態に係る超音波溶着機の使用状態を示す側面図、図５は埋込み溶着に使用されるインサートねじを示す側面図である。
本実施の形態では図５に示すようなインサートねじ３５を被溶着物Ａとし、当該インサートねじ３５を合成樹脂製のワークＷの表面７に埋込み溶着し、ワークＷの表面７にねじ穴を形成する場合に使用できる超音波溶着機１１を示している。
尚、図５中、φＩはインサートねじ３５の外径、ＬＩはインサートねじ３５の長さである。
又、超音波溶着機１１の基本的構成については上記第１の実施の形態と同様であるので、ここではその説明は省略し、第１の実施の形態と相違する構成を中心に説明する。 (2) Second embodiment (see FIGS. 4 and 5)
FIG. 4 is a side view showing a use state of the ultrasonic welding machine according to the second embodiment, and FIG. 5 is a side view showing an insert screw used for embedded welding.
In the present embodiment, an insert screw 35 as shown in FIG. 5 is used as an object to be welded A, and the insert screw 35 is embedded and welded to the surface 7 of the synthetic resin workpiece W to form a screw hole in the surface 7 of the workpiece W. The ultrasonic welding machine 11 which can be used when doing is shown.
In FIG. 5, φ I is the outer diameter of the insert screw 35, and L I is the length of the insert screw 35.
Since the basic configuration of the ultrasonic welder 11 is the same as that of the first embodiment, the description thereof will be omitted here, and a description will be given focusing on the configuration different from the first embodiment.

まず、ゴム状弾性体２９のチューブ内径φＴは上記第１の実施の形態と同様、ゴム状弾性体２９の自重でホーン１５の先端部１７からゴム状弾性体２９が外れてしまわない程度の大きさに設定されている。又、ホーン１５の先端部１７の直径φＨとゴム状弾性体２９のチューブ内径φＴとの間にはφＨがφＴに比べて大きくなり過ぎないよう、好ましくはφＴ＝φＨ±０．５ｍｍの範囲内に収まるように設定されている。
又、ゴム状弾性体２９のチューブ内径φＴはインサートねじ３５の外径φＩと同等か大きい方が好ましいが、大き過ぎるとホーン１５内でインサートねじ３５が動いてしまうため、φＴとφＩとの間に例えばφＩ＋２ｍｍ程度≧φＴ≧φＩの関係が成立するように設定する。 First, Bore phi T of the rubber-like elastic body 29 is similar to that of the first embodiment, the tip 17 of the horn 15 by the weight of the rubber-like elastic material 29 as not Shimawa off the rubber-like elastic material 29 The size is set. Also, to avoid too large compared to the phi H is phi T between the tube inner diameter phi T of diameter phi H and the rubber-like elastic body 29 of the tip 17 of the horn 15, preferably φ T = φ H ± It is set to be within a range of 0.5 mm.
Further, since the tube inside diameter phi T of the rubber-like elastic body 29 is more preferable greater than or equal to the outside diameter phi I of the insert screw 35, which results in moving the insert screw 35 is too large horn 15 inside, phi T and phi relationship example phi I + 2 mm approximately ≧ φ T ≧ φ I between I is set to satisfy.

又、ゴム状弾性体２９のチューブ長さＬＴは上記第１の実施の形態と同様、ホーン１５の先端部１７の長さＬＨより長くなるように設定する。具体的にはゴム状弾性体２９のチューブ長さＬＴはホーン１５の先端部１７の長さＬＨにインサートねじ３５の長さＬＩを加えた長さに設定することが好ましい。因みにこのような長さに設定することによってゴム状弾性体２９とインサートねじ３５との係止状態が作業中維持されるから、ゴム状弾性体２９からインサートねじ３５が外れてしまう事態が防止される。
又、シリコーンチューブの有する弾性力によってインサートねじ３５がワークＷの表面７に埋め込まれる時にゴム状弾性体２９は縮むため、インサートねじ３５の円滑な埋め込みが実行される。 Also, tube length L T of the rubber-like elastic material 29 is similar to the above first embodiment, set to be longer than the length L H of the tip 17 of the horn 15. Tube Length of specifically rubbery elastomer 29 L T is preferably set to a length obtained by adding the length L I of the insert screw 35 to the length L H of the tip 17 of the horn 15. Incidentally, by setting such a length, the locked state between the rubber-like elastic body 29 and the insert screw 35 is maintained during the operation, so that the situation where the insert screw 35 is detached from the rubber-like elastic body 29 is prevented. The
Further, since the rubber-like elastic body 29 contracts when the insert screw 35 is embedded in the surface 7 of the workpiece W by the elastic force of the silicone tube, the insert screw 35 is smoothly embedded.

そしてこのような構成の超音波溶着機１１を使用して図４に示すようにワークＷの表面７にインサートねじ３５を超音波溶着する場合には、以下のような作業手順で超音波溶着を実行する。まず、図４に示すようにゴム状弾性体２９をホーン１５の先端部１７に装着し、ゴム状弾性体２９の内方空間３３内にインサートねじ３５を入れ、インサートねじ３５を埋込み溶着するワークＷの表面７の所定の部位にインサートねじ３５を位置させる。
この状態で切替えスイッチ２３を押すと、超音波発振器１３から超音波振動が発せられ、ホーン１５によって増幅された超音波振動がワークＷの接合部１となる表面７に伝わって摩擦熱を発生させ、当該部位を溶融させる。そしてワークＷの溶融に伴ってインサートねじ３５がワークＷ内に没入するようになり、その状態でワークＷを硬化させればワークＷ内へのインサートねじ３５の埋込み溶着加工が完了する。 Then, when the insert screw 35 is ultrasonically welded to the surface 7 of the workpiece W as shown in FIG. 4 using the ultrasonic welder 11 having such a configuration, the ultrasonic welding is performed by the following work procedure. Execute. First, as shown in FIG. 4, a rubber-like elastic body 29 is attached to the tip 17 of the horn 15, an insert screw 35 is inserted into the inner space 33 of the rubber-like elastic body 29, and the insert screw 35 is embedded and welded. The insert screw 35 is positioned at a predetermined portion of the surface 7 of W.
When the changeover switch 23 is pressed in this state, ultrasonic vibration is emitted from the ultrasonic oscillator 13, and the ultrasonic vibration amplified by the horn 15 is transmitted to the surface 7 that becomes the joint 1 of the workpiece W to generate frictional heat. , Melt the part. As the work W is melted, the insert screw 35 comes into the work W. If the work W is hardened in this state, the process of embedding the insert screw 35 in the work W is completed.

このような構成の超音波溶着機１１によると、極めて簡単な構成で位置決め部材１９を構成でき、筒状のゴム状弾性体２９の先端部の内方空間３３内にインサートねじ３５を収容するだけで当該インサートねじ３５を保持することができる。又、ゴム状弾性体２９の内方空間３３とインサートねじ３５との係止状態は超音波溶着開始前のセット時から超音波溶着完了時までの間、持続され、尚且つ、ゴム状弾性体２９の有する摩擦抵抗によって左右及び前後方向のホーン１５とインサートねじ３５の位置ずれが防止され、従来インサートねじ３５を固定するためにワークＷの表面７に設けていた下穴を省略することが可能になる。   According to the ultrasonic welding machine 11 having such a configuration, the positioning member 19 can be configured with a very simple configuration, and the insert screw 35 is only accommodated in the inner space 33 at the tip of the cylindrical rubber-like elastic body 29. Thus, the insert screw 35 can be held. Further, the engagement state between the inner space 33 of the rubber-like elastic body 29 and the insert screw 35 is maintained from the set time before the start of ultrasonic welding until the completion of the ultrasonic welding, and the rubber-like elastic body. The frictional resistance 29 has prevented the displacement of the horn 15 and the insert screw 35 in the left and right and front and rear directions, and the pilot hole provided on the surface 7 of the workpiece W for fixing the insert screw 35 can be omitted. become.

又、ゴム状弾性体２９の有する耐熱性によってワークＷの接合部１が溶融してもゴム状弾性体２９の熱変形等は生じない。またゴム状弾性体２９としてシリコーンチューブを使用したことにより、適度な硬さと弾性力が得られるため、ワークＷの接合部１の溶着後の形状変化にも対応でき、ホーン１５の作業中の姿勢の安定性も保たれる。
そして作業性が良く、種々の大きさや形状のワークＷ、被溶着物Ａ及びワークＷの接合部１に対して適用することができ、しかも構造が簡単で安価な超音波溶着機１１を提供することが可能になる。 Further, due to the heat resistance of the rubber-like elastic body 29, even if the joining portion 1 of the workpiece W is melted, the rubber-like elastic body 29 is not thermally deformed. Moreover, since a moderate hardness and elastic force can be obtained by using a silicone tube as the rubber-like elastic body 29, it is possible to cope with a shape change after welding of the joint 1 of the workpiece W, and the posture of the horn 15 during operation. Stability is also maintained.
An ultrasonic welding machine 11 is provided that has good workability, can be applied to the workpiece W of various sizes and shapes, the workpiece A, and the joint 1 of the workpiece W, and has a simple structure and is inexpensive. It becomes possible.

（３）第３の実施の形態（図６参照）
図６は第３の実施の形態に係る超音波溶着機の使用状態を示す側面図である。
本実施の形態では図６に示すように表面７に接合部１となる突起３７を備える合成樹脂製のワークＷに、合成樹脂製の被溶着物Ａを直接溶着する場合に使用できる超音波溶着機１１を示している。
尚、超音波溶着機１１の基本的構成については上記第１及び第２の実施の形態と同様であるので、ここではその説明は省略し、第１及び第２の実施の形態と相違する構成を中心に説明する。 (3) Third embodiment (see FIG. 6)
FIG. 6 is a side view showing a usage state of the ultrasonic welder according to the third embodiment.
In the present embodiment, as shown in FIG. 6, ultrasonic welding that can be used when a synthetic resin workpiece W is directly welded to a synthetic resin workpiece W provided with a projection 37 that becomes the joint 1 on the surface 7. The machine 11 is shown.
Since the basic configuration of the ultrasonic welder 11 is the same as that of the first and second embodiments, the description thereof is omitted here, and the configuration is different from the first and second embodiments. The explanation will be focused on.

まず、ゴム状弾性体２９のチューブ内径φＴは上記第１及び第２の実施の形態と同様、ゴム状弾性体２９の自重でホーン１５の先端部１７からゴム状弾性体２９が外れてしまわない程度の大きさに設定されている。又、ホーン１５の先端部１７の直径φＨとゴム状弾性体２９のチューブ内径φＴとの間にはφＨがφＴに比べて大きくなり過ぎないよう、好ましくはφＴ＝φＨ±０．５ｍｍの範囲内に収まるように設定されている。
又、ゴム状弾性体２９のチューブ長さＬＴは上記第１及び第２の実施の形態と同様、ホーン１５の先端部１７の長さＬＨより長くなるように設定する。具体的にはゴム状弾性体２９のチューブ長さＬＴはホーン１５の先端部１７の長さＬＨより長く、ホーン１５の先端部１７の長さＬＨに約１ｍｍ程度加えた長さと同じ長さか、ＬＨより短くならない範囲で、それより短い長さに設定する。因みにこのような長さにすればゴム状弾性体２９の弾性作用範囲内でホーン１５の先端部１７の端面３１が被溶着物Ａの表面に当接することができるようになる。 First, Bore phi T of the rubber-like elastic body 29 is similar to the first and second embodiments, Shimawa off the rubber-like elastic material 29 from the tip 17 of the horn 15 by the weight of the rubber-like elastic material 29 It is set to a size that is not. Also, to avoid too large compared to the phi H is phi T between the tube inner diameter phi T of diameter phi H and the rubber-like elastic body 29 of the tip 17 of the horn 15, preferably φ T = φ H ± It is set to be within a range of 0.5 mm.
Also, tube length L T of the rubber-like elastic material 29 is similar to the first and second embodiments, set to be longer than the length L H of the tip 17 of the horn 15. Specifically, the tube length L T of the rubber-like elastic body 29 longer than the length L H of the tip 17 of the horn 15, the same as the length obtained by adding about 1mm approximately the length L H of the tip 17 of the horn 15 the length, in a range of not less than L H, set it shorter length. Incidentally, when such a length is used, the end surface 31 of the tip 17 of the horn 15 can come into contact with the surface of the workpiece A within the elastic action range of the rubber-like elastic body 29.

そしてこのような構成の超音波溶着機１１を使用して図６に示すようにワークＷの表面７に被溶着物Ａを直接溶着する場合には、以下のような作業手順で超音波溶着を実行する。まず、図６に示すようにワークＷと被溶着物Ａを接合する所定の量だけ重ね合わせておく。次にゴム状弾性体２９をホーン１５の先端部１７に装着し、直接溶着する被溶着物Ａの表面の所定の部位に超音波溶着機１１を位置させる。
この状態で切替えスイッチ２３を押すと、超音波発振器１３から超音波振動が発せられ、ホーン１５によって増幅されて被溶着物Ａの表面に伝達される。被溶着物Ａの表面に伝達された超音波振動は被溶着物Ａ及びその下方のワークＷの突起３７に摩擦熱を発生させ、これらの部位を溶融させる。そしてその状態でワークＷ及び被溶着物Ａを硬化させればワークＷと被溶着物Ａとの直接溶着加工が完了する。 When the welding object A is directly welded to the surface 7 of the workpiece W as shown in FIG. 6 using the ultrasonic welding machine 11 having such a configuration, the ultrasonic welding is performed by the following operation procedure. Execute. First, as shown in FIG. 6, the workpiece W and the workpiece A are overlapped by a predetermined amount for joining. Next, the rubber-like elastic body 29 is attached to the tip portion 17 of the horn 15, and the ultrasonic welder 11 is positioned at a predetermined portion on the surface of the workpiece A to be welded directly.
When the changeover switch 23 is pressed in this state, ultrasonic vibration is emitted from the ultrasonic oscillator 13, amplified by the horn 15, and transmitted to the surface of the object A to be welded. The ultrasonic vibration transmitted to the surface of the object to be welded A generates frictional heat on the object A to be welded and the projections 37 of the workpiece W therebelow, thereby melting these portions. And if the workpiece | work W and the to-be-welded material A are hardened in the state, the direct welding process of the workpiece | work W and the to-be-welded material A will be completed.

このような構成の超音波溶着機１１によると、極めて簡単な構成で位置決め部材１９を構成でき、ゴム状弾性体２９の有する摩擦抵抗によって左右及び前後方向のホーン１５の位置ずれが防止される。
又、ゴム状弾性体２９の有する耐熱性によってワークＷの接合部１が溶融してもゴム状弾性体２９の熱変形等は生じない。またゴム状弾性体２９としてシリコーンチューブを使用したことにより、適度な硬さと弾性力が得られるため、ワークＷの接合部１の溶着後の形状変化にも対応でき、ホーン１５の作業中の姿勢の安定性も保たれる。
そして作業性が良く、種々の大きさや形状のワークＷ、被溶着物Ａ及びワークＷの接合部１に対して適用することができ、しかも構造が簡単で安価な超音波溶着機１１を提供することが可能になる。 According to the ultrasonic welder 11 having such a configuration, the positioning member 19 can be configured with an extremely simple configuration, and the displacement of the horn 15 in the left and right and front and rear directions is prevented by the frictional resistance of the rubber-like elastic body 29.
Further, due to the heat resistance of the rubber-like elastic body 29, even if the joining portion 1 of the workpiece W is melted, the rubber-like elastic body 29 is not thermally deformed. Moreover, since a moderate hardness and elastic force can be obtained by using a silicone tube as the rubber-like elastic body 29, it is possible to cope with a shape change after welding of the joint 1 of the workpiece W, and the posture of the horn 15 during operation. Stability is also maintained.
An ultrasonic welding machine 11 is provided that has good workability, can be applied to the workpiece W of various sizes and shapes, the workpiece A, and the joint 1 of the workpiece W, and has a simple structure and is inexpensive. It becomes possible.

（４）第４の実施の形態（図７参照）
図７は第４の実施の形態に係る超音波溶着機の使用状態を示す側面図である。図７に示す本実施の形態では接合部１に突起形状のボス３が形成されている合成樹脂製のワークＷと、穴５が形成されている被溶着物Ａとをカシメ溶着する場合に使用できる超音波溶着機４１を示している。
超音波溶着機４１の基本的構成については上記第１〜第３の実施の形態と同様であるので、ここではその説明は省略し、第１〜第３の実施の形態と相違する構成を中心に説明する。 (4) Fourth embodiment (see FIG. 7)
FIG. 7 is a side view showing a usage state of the ultrasonic welder according to the fourth embodiment. In the present embodiment shown in FIG. 7, it is used when caulking and welding a synthetic resin workpiece W having a projection-shaped boss 3 formed on a joint 1 and a workpiece A having a hole 5 formed thereon. A possible ultrasonic welder 41 is shown.
Since the basic configuration of the ultrasonic welder 41 is the same as that of the first to third embodiments, the description thereof is omitted here, and the configuration different from the first to third embodiments is mainly described. Explained.

本実施の形態では位置決め部材１９の構成が上記第１〜第３の実施の形態と相違している。即ち、本実施の形態では位置決め部材１９はホーン１５の外周部に取り付けられるフロントケース４３と、該フロントケース４３内を摺動するスライドケース４５と、上記フロントケース４３内に縮設され、上記スライドケース４５を突出方向（図７中、下方）に付勢する付勢手段としての圧縮コイルばね４７とを具備することによって構成されている。
フロントケース４３はケース２１の下方、そしてホーン１５の基部２５の外周部に固定状態で取り付けられる上下両面が開放された円筒状の部材である。又、フロントケース４３の下部の空間は上記圧縮コイルばね４７と上記スライドケース４５との収容スペース４９になっており、該収容スペース４９の上部には上記圧縮コイルばね４７の上端面に当接するよう内側にリンク状に張り出したばね係止部５１が設けられている。一方、上記収容スペース４９の下部にはスライドケース４５の次に述べる上部のフランジ部５３の下面に当接するよう内側にリング状に張り出したフランジ係止部５５が設けられている。 In the present embodiment, the configuration of the positioning member 19 is different from those of the first to third embodiments. That is, in the present embodiment, the positioning member 19 is a front case 43 attached to the outer periphery of the horn 15, a slide case 45 that slides in the front case 43, and is retracted in the front case 43, and the slide A compression coil spring 47 is provided as a biasing means for biasing the case 45 in the protruding direction (downward in FIG. 7).
The front case 43 is a cylindrical member that is attached to the lower side of the case 21 and the outer peripheral portion of the base portion 25 of the horn 15 in a fixed state and is open on both upper and lower sides. The space below the front case 43 is a storage space 49 for the compression coil spring 47 and the slide case 45, and the upper portion of the storage space 49 is in contact with the upper end surface of the compression coil spring 47. A spring locking portion 51 is provided on the inside so as to project in a link shape. On the other hand, a flange locking portion 55 projecting in a ring shape on the inner side is provided at the lower portion of the housing space 49 so as to contact the lower surface of the upper flange portion 53 described below of the slide case 45.

上記スライドケース４５の先端内周部は先端に向かって徐々に拡大されるようなテーパ部４５ａとなっている。このようなテーパ部４５ａを設けることにより、ホーン１５によって増幅した超音波振動によって溶融したワークＷの一部が広がり易い構成になっている。そして、ワークＷの接合部１の溶け込み高さに作用して上記スライドケース４５がフロントケース４３の内部へ収容されていることになる。
又、上記フランジ部５３の外径は上記フロントケース４３の内周面にフランジ部５３の外周面が摺接するようにフロントケース４３の内径より幾分小さめに形成されている。
又、スライドケース４５の内径は第１の実施の形態で示したゴム状弾性体とホーンとの関係で同等条件となっている。 The inner peripheral portion of the tip of the slide case 45 is a tapered portion 45a that gradually expands toward the tip. By providing such a tapered portion 45a, a part of the workpiece W melted by the ultrasonic vibration amplified by the horn 15 is easily spread. Then, the slide case 45 is accommodated in the front case 43 by acting on the penetration height of the joint 1 of the workpiece W.
Further, the outer diameter of the flange portion 53 is formed slightly smaller than the inner diameter of the front case 43 so that the outer peripheral surface of the flange portion 53 is in sliding contact with the inner peripheral surface of the front case 43.
Further, the inner diameter of the slide case 45 is equivalent under the relationship between the rubber-like elastic body and the horn shown in the first embodiment.

そしてこのような構成の超音波溶着機１１を使用して図７に示すようなボス３を有するワークＷと穴５を有する被溶着物Ａを超音波溶着する場合には以下のような作用手順で超音波溶着を実行する。まず、図７に示すようにワークＷの接合部１に形成されているボス３を被溶着物Ａの穴５に挿し込んだ状態にする。
次にスライドケース４５を図７に示すようにボス３に被せるようにして超音波溶着機１１をセットする。 When ultrasonic welding is performed on the workpiece W having the boss 3 and the workpiece A having the hole 5 as shown in FIG. Perform ultrasonic welding with. First, as shown in FIG. 7, the boss 3 formed at the joint 1 of the workpiece W is inserted into the hole 5 of the workpiece A.
Next, the ultrasonic welding machine 11 is set so that the slide case 45 is placed on the boss 3 as shown in FIG.

この状態でケース２１を持って超音波溶着機４１を下方に押し込みながら切替えスイッチ２３を押すと、超音波発振器１３から超音波振動が発せられ、ホーン１５によって増幅された超音波振動がスライドケース４５を介してボス３に伝達される。
又、ボス３に伝達された超音波振動によってボス３には摩擦熱が発生してボス３を溶融させる。溶融と共に変化するボスの高さと連動してスライドケース４５は収縮する。そしてその状態でボス３を硬化させればワークＷと被溶着物Ａのカシメ溶着加工が完了する。 In this state, when the changeover switch 23 is pressed while pushing the ultrasonic welder 41 downward while holding the case 21, ultrasonic vibration is emitted from the ultrasonic oscillator 13, and the ultrasonic vibration amplified by the horn 15 is converted into the slide case 45. Is transmitted to the boss 3 via.
The ultrasonic vibration transmitted to the boss 3 generates frictional heat in the boss 3 and melts the boss 3. The slide case 45 contracts in conjunction with the height of the boss that changes with melting. And if the boss | hub 3 is hardened in that state, the crimping welding process of the workpiece | work W and the to-be-welded object A will be completed.

このような構成の超音波溶着機４１によると、ホーン１５の先端部１７の端面３１の露出が防止されるからホーン１５の先端部１７の端面３１に傷を付けたり、汚れを付着させることがなく、ホーン１５の損傷を防止することができる。又、上記圧縮コイルばね４７の有する弾性力によってセット時に生ずるスライドケース４５と被溶着物Ａとの間の衝突時の衝撃も緩和される。
又、上記第１〜第４の実施の形態に共通する作用、効果としてホーン１５の先端部１７の端面３１にローレット加工等の滑り止め加工を施さなくてもよいから、当該加工に要する労力やコストが削減でき、超音波溶着によってできた溶着痕にローレット加工等の凹凸模様が付くこともない。 According to the ultrasonic welding machine 41 having such a configuration, the end surface 31 of the tip portion 17 of the horn 15 is prevented from being exposed, so that the end surface 31 of the tip portion 17 of the horn 15 can be scratched or contaminated. In addition, damage to the horn 15 can be prevented. Moreover, the impact at the time of a collision between the slide case 45 and the to-be-welded object A which arises at the time of setting with the elastic force which the said compression coil spring 47 has is also relieve | moderated.
Moreover, since it is not necessary to perform anti-slip processing such as knurling on the end surface 31 of the tip portion 17 of the horn 15 as an operation and effect common to the first to fourth embodiments, Costs can be reduced, and uneven patterns such as knurling are not attached to welding marks formed by ultrasonic welding.

尚、本発明は上述した第１〜第４の実施の形態に限定されるものではない。例えばホーン１５の形状は径違いの丸棒形状に限らず、径違いの角棒形状であってもよく、これに対応してゴム状弾性体２９やフロントケース４３等の形状を円筒形状から角筒形状に変更することが可能である。
又、上記第４の実施の形態で設けた圧縮コイルばね４７は省略することが可能であり、圧縮コイルばね４７に代えてエアダンパ等、他の付勢手段を採用することも可能である。 In addition, this invention is not limited to the 1st-4th embodiment mentioned above. For example, the shape of the horn 15 is not limited to a round bar shape with a different diameter, but may be a square bar shape with a different diameter. Correspondingly, the shape of the rubber-like elastic body 29, the front case 43, etc. is changed from a cylindrical shape to a square shape. It is possible to change to a cylindrical shape.
Further, the compression coil spring 47 provided in the fourth embodiment can be omitted, and other urging means such as an air damper can be employed in place of the compression coil spring 47.

本発明は、超音波振動によって発生した摩擦熱を利用してワークと被溶着物とを溶着する超音波溶着機の製造、使用分野等で利用でき、特にハンディータイプの超音波溶着機においてワークとホーンが滑ることなく超音波溶着作業を行いたい場合に利用可能性を有する。   INDUSTRIAL APPLICABILITY The present invention can be used in the manufacture of ultrasonic welders that use a frictional heat generated by ultrasonic vibration to weld a workpiece and an object to be welded, in the field of use, and the like, particularly in a handy type ultrasonic welder.
