Description

本発明は、振動溶着装置に関し、更に詳しくは、振動体や治具を９０°回転させることにより、振動方向や治具の取着方向、溶着する樹脂部品を治具に取着する際の取付方向等の自由度を向上させることができる振動溶着装置に関する。 The present invention relates to a vibration welding apparatus, and more specifically, by rotating a vibrating body or jig by 90 °, the vibration direction, the attachment direction of the jig, and the attachment when attaching a resin part to be welded to the jig. The present invention relates to a vibration welding apparatus capable of improving the degree of freedom of direction and the like.

２つの樹脂部品を加圧しながら当接させ、その当接面に振動による摩擦熱を発生させて２つの樹脂部品を溶着させる振動溶着装置が知られている。このような装置では、従来、振動が一方向のみの往復直線振動であるため、溶着する樹脂部品やその治具を設計する際に、製品の寸法や装置の許容製品寸法と共に、溶着時の振動方向も考慮する必要があった。   2. Description of the Related Art A vibration welding apparatus is known in which two resin parts are brought into contact with each other while being pressurized, and frictional heat due to vibration is generated on the contact surface to weld the two resin parts. Conventionally, in such a device, the vibration is a reciprocating linear vibration in only one direction. Therefore, when designing a resin part to be welded and its jig, the vibration during welding as well as the product dimensions and the allowable product dimensions of the device. It was also necessary to consider the direction.

そのような中で、２つの電磁式バイブレーターを用いて、直交する２方向への振動が可能な溶着装置が提案されている（例えば、特許文献１参照）。この装置では、２方向への振動が可能なので、一方向のみに振動する装置と比較して、製品及び治具の設計の際の自由度が高い。しかしながら、この装置では、上下の２つの電磁式バイブレーターを備えているので、構造が複雑になり、コストもかかる。
また、このような装置では、治具を装置に取着する際に、溶着時の方向に合わせて治具を取着する必要があり、その方向に合わせた方向を向けて治具を段取りしておく必要があった。 Under such circumstances, a welding apparatus that can vibrate in two orthogonal directions using two electromagnetic vibrators has been proposed (see, for example, Patent Document 1). Since this apparatus can vibrate in two directions, the degree of freedom in designing products and jigs is higher than that of an apparatus that vibrates in only one direction. However, since this apparatus includes two upper and lower electromagnetic vibrators, the structure becomes complicated and the cost is high.
Moreover, in such an apparatus, when attaching a jig to an apparatus, it is necessary to attach a jig according to the direction at the time of welding, and set up a jig in the direction according to the direction. It was necessary to keep.

静止側回転機構１６は、テーブル１２の下面側に設けられており、図３に示すように、ベース１２ａにその上端側が固定され、テーブル１２を貫通して下方に伸びる回転軸１６ａ（本発明に係る回動部材として例示する。）を有している。回転軸１６ａは、軸受１６ｂを介して、ベース１２ａを回動自在に軸支している。回転軸１６ａの下端側にはレバー１６ｃが設けられており、その一端側が回転軸１６ａに固定されている。レバー１６ｃは、図４に示すように、回転軸１６ａの遠心方向に伸びるように設けられており、その先端側にはシリンダ１６ｄのロッドが連結されている。このような機構により、ベース１２ａに取着された下側治具１４は、図３に示す軸Ａを中心として９０°回転する。
また、静止側回転機構１６は、図３に示すように、シリンダと、そのロッドの先端に取着されたピンと、を有する位置保持手段１６ｅを備えており、回転後のベース１２ａの位置を保持する。この位置保持手段１６ｅは、シリンダの駆動により、ベース１２ａの端部に設けられた孔１２ｂにピンを挿入してその位置を保持する。 The stationary-side rotation mechanism 16 is provided on the lower surface side of the table 12, and as shown in FIG. 3, the upper end side is fixed to the base 12a and extends downward through the table 12 (according to the present invention).

As shown in FIG. 4, the lever 16c is provided so as to extend in the centrifugal direction of the rotary shaft 16a, and the rod of the cylinder 16d is connected to the tip side thereof. With such a mechanism, the lower jig 14 attached to the base 12a rotates 90 ° around the axis A shown in FIG.
Further, as shown in FIG. 3, the stationary side rotation mechanism 16 includes a position holding means 16e having a cylinder and a pin attached to the tip of the rod, and holds the position of the base 12a after the rotation.

（２）振動溶着装置の作用
次に、上記構成の振動溶着装置１の作用について説明する。 (2) Operation of Vibration Welding Device Next, the operation of the vibration welding device 1 having the above configuration will be described.

最初に、上側治具１３及び下側治具１４の着脱について説明する。
まず、治具１３、１４を取着する際には、図５（ａ）に示すように、上側治具１３がその上面側に載置された状態の下側治具１４をテーブル１２のベース１２ａに取着する。このとき、下側治具１４及び上側治具１３を溶着時の方向に合わせて取着する必要はなく、９０°回転した状態で取着してもよい。その場合には、下側治具１４をベース１２ａに固定した後に、静止側回転機構１６により回転させる。また、このとき、この治具１３、１４を用いて溶着する部材２、３の振動方向により、振動体１１の方向を予め選択しておく。即ち、例えば、図５（ａ）における現在の振動方向がＸ方向であり、溶着時の振動方向がＹ方向である場合には、振動側回転機構１５により、振動体１１がＹ方向へ振動するように予め回転させておく。また、下側治具１４上に載置されている上側治具１３の方向が振動体１１に取着される方向と異なっている場合には、静止側回転機構１６により、その向きを予め合わせておく。 First, attachment / detachment of the upper jig 13 and the lower jig 14 will be described.
First, when attaching the jigs 13 and 14, as shown in FIG. 5 (a), the lower jig 14 with the upper jig 13 placed on the upper surface thereof is used as the base of the table 12. Attach to 12a. At this time, it is not necessary to attach the lower jig 14 and the upper jig 13 in accordance with the welding direction, and they may be attached in a state rotated by 90 °. In that case, after the lower jig 14 is fixed to the base 12a, it is rotated by the stationary rotation mechanism 16. At this time, the direction of the vibrating body 11 is selected in advance according to the vibration direction of the members 2 and 3 to be welded using the jigs 13 and 14. That is, for example, when the current vibration direction in FIG. 5A is the X direction and the vibration direction at the time of welding is the Y direction, the vibration body 11 vibrates in the Y direction by the vibration side rotation mechanism 15. Rotate beforehand. Further, when the direction of the upper jig 13 placed on the lower jig 14 is different from the direction attached to the vibrating body 11, the direction is adjusted in advance by the stationary side rotation mechanism 16. Keep it.

次に、図５（ｂ）に示すように、昇降機構１８により、テーブル１２、下側治具１４及び下側治具１４上に載置された上側治具１３を上昇させ、上側治具１３の上面側を振動体１１の下面側に当接させ、この状態で上側治具１３の取着作業を行う。
最後に、図５（ｃ）に示すように、下側治具１４及びテーブル１２を下降させる。これにより、テーブル１２側には下側治具１４が、振動体１１には上側治具１３がそれぞれ取着される。
治具１３、１４を取り外す際には、上記手順を反対に実行する。 Next, as shown in FIG. 5B, the lifting mechanism 18 raises the table 12, the lower jig 14, and the upper jig 13 placed on the lower jig 14 to raise the upper jig 13. The upper surface side of the upper jig 13 is brought into contact with the lower surface side of the vibrating body 11, and the upper jig 13 is attached in this state.
Finally, as shown in FIG. 5C, the lower jig 14 and the table 12 are lowered. Accordingly, the lower jig 14 is attached to the table 12 side, and the upper jig 13 is attached to the vibrating body 11.
When removing the jigs 13 and 14, the above procedure is executed in reverse.

続いて、振動溶着による２部材の接合について説明する。
最初に、図６（ａ）に示すように、上側治具１３の保持部１３ａに上側部材２を固定すると共に、下側治具１４の保持部１４ａに、下側部材３を固定する。そして、図６（ｂ）に示すように、昇降機構１８によりテーブル１２、下側治具１４及び下側部材３を上昇させる。これにより、上側部材２と下側部材３とが当接し、加圧される。この加圧された状態で、振動体１１を振動させ、上側部材２と下側部材３との当接面に摩擦を生じさせる。これにより、当接面の樹脂が溶融状態となる。このとき、上側治具１３及び下側治具１４は、振動側回転機構１５及び静止側回転機構１６の位置保持手段によりその位置を保持されており、振動によりずれが生じることはない。更に、上側部材２と下側部材３との当接面が溶融状態となっても、昇降機構１８により加圧状態を維持する。そして、所定の時間が経過したところで振動を停止すると、溶融状態にあった上側部材２と下側部材３との当接面が再び凝固して、上側部材２及び下側部材３が接合される。
最後に、図６（ｃ）に示すように、テーブル１２を下降させると、接合して一体化した上側部材２及び下側部材３も共に下降する。 Subsequently, the joining of two members by vibration welding will be described.
First, as shown in FIG. 6A, the upper member 2 is fixed to the holding portion 13 a of the upper jig 13, and the lower member 3 is fixed to the holding portion 14 a of the lower jig 14. Then, as shown in FIG. 6B, the table 12, the lower jig 14, and the lower member 3 are raised by the lifting mechanism 18. As a result, the upper member 2 and the lower member 3 come into contact with each other and are pressurized. In this pressurized state, the vibrating body 11 is vibrated to cause friction on the contact surface between the upper member 2 and the lower member 3. Thereby, the resin of the contact surface is in a molten state. At this time, the positions of the upper jig 13 and the lower jig 14 are held by the position holding means of the vibration-side rotation mechanism 15 and the stationary-side rotation mechanism 16, and no deviation occurs due to vibration. Furthermore, even if the contact surface between the upper member 2 and the lower member 3 is in a molten state, the elevated state is maintained by the lifting mechanism 18. When the vibration is stopped when a predetermined time has elapsed, the contact surfaces of the upper member 2 and the lower member 3 that have been in a molten state are solidified again, and the upper member 2 and the lower member 3 are joined. .
Finally, as shown in FIG. 6C, when the table 12 is lowered, the upper member 2 and the lower member 3 which are joined and integrated together are also lowered.

ここで、本装置１が生産ラインに組み込まれた場合等において、図７（ａ）に示すように、溶着完了後の下側治具１４に載置された状態の部材２、３を、図７（ｂ）に示すように、静止側回転機構１６を用いて回転させることにより、その向きを９０°回転させて装置１から搬出するようにしてもよい。
また、装置の許容製品寸法に制限があり、治具を長手方向（Ｘ方向）にしか設置することができず、且つ振動させる方向は長手方向と直交する方向（Ｙ方向）である場合でも、振動側回転機構１５を用いて振動体１１を回転させ、振動体１１をＹ方向に振動させるようにすることで対応できる。 Here, when the present apparatus 1 is incorporated in a production line, as shown in FIG. 7A, the members 2 and 3 placed on the lower jig 14 after the completion of welding are shown in FIG. As shown in FIG. 7 (b), the rotation may be carried out by using the stationary side rotation mechanism 16 so that the direction is rotated by 90 ° and the apparatus 1 is carried out.
In addition, even if the allowable product size of the apparatus is limited, the jig can be installed only in the longitudinal direction (X direction), and the direction of vibration is the direction orthogonal to the longitudinal direction (Y direction), This can be dealt with by rotating the vibrating body 11 using the vibration-side rotating mechanism 15 so as to vibrate the vibrating body 11 in the Y direction.

（３）実施例の効果
