Description

本発明は、アンビルに装着したセンサにより、振動及び圧力を検出して、溶着状態を表示きる超音波溶着器に関するものである。   The present invention relates to an ultrasonic welder that can detect vibration and pressure by a sensor mounted on an anvil and display a welding state.

従来、図２及び図３に示すように、ハンドピース１の一端に超音波振動子２のホーン２ａの端部が突出され、ハンドピース１の側部にアンビル部３の摺動部材３ａが摺動可能に装着され、摺動部材３ａからアンビル３ｂがほぼ垂直に形成され、アンビル３ｂの端部は超音波振動子２のホーン２ａの端部と接触するように構成され、ハンドピース１の両側面に装着された回動軸４で回動部材５の三角部材５ａの頂点部分が支持され、又、回動部材５は三角部材５ａからハンドピース１の下方に斜めにレバー５ｂが形成され、さらに、回動部材５の三角部材５ａの底部近傍に駆動軸６が固着され、又、アンビル部３の摺動部材３ａを貫通して支持軸７が摺動部材３ａに固着され、駆動軸６と支持軸７の間にＵ字状のバネ８が装着され、又、ハンドピース１の側部に発振スイッチ９が装着され、レバー３ｂに装着した突出部５ｃで発振スイッチ９を押すようにした超音波溶着装置が提案されている。   Conventionally, as shown in FIG. 2 and FIG. 3, the end of the horn 2 a of the ultrasonic transducer 2 protrudes from one end of the hand piece 1, and the sliding member 3 a of the anvil part 3 slides on the side of the hand piece 1. The anvil 3b is mounted so as to be movable, and the anvil 3b is formed substantially vertically from the sliding member 3a. The end of the anvil 3b is configured to come into contact with the end of the horn 2a of the ultrasonic vibrator 2, and The rotating shaft 4 mounted on the surface supports the apex portion of the triangular member 5a of the rotating member 5, and the rotating member 5 is formed with a lever 5b obliquely below the handpiece 1 from the triangular member 5a. Further, the drive shaft 6 is fixed to the vicinity of the bottom of the triangular member 5 a of the rotating member 5, and the support shaft 7 is fixed to the slide member 3 a through the sliding member 3 a of the anvil portion 3. A U-shaped spring 8 is mounted between the support shaft 7 and the hand. Over side to the oscillation switch 9 of the scan 1 is mounted, the ultrasonic welding apparatus that pushes the oscillation switch 9 protruding portion 5c attached to the lever 3b are proposed.

しかしながら、この超音波溶着装置では、被溶着物１０を溶着する場合は、回動部材５のレバー５ｂを握ることにより、レバー５ｂの突出部５ｃが発振スイッチ９を押すことにより、超音波振動子２が振動して、アンビル３ｂと超音波振動子２のホーン２ａの間に挟持された被溶着物１７が溶着されるが、レバー５ｂを握る時間がまちまちであり、又、レバー５ｂを握る圧力もまちまちであるので、溶着が完了した後でもレバー５ｂを握っていると、被溶着物１０が必要以上に溶けてしまい、本来、被溶着物１０の密閉されている部分が密閉されていなかったり、焦げが発生してりして、溶着部分に不良が発生するという問題がある。
特願２００４−２８７７５６ However, in this ultrasonic welding apparatus, when the workpiece 10 is to be welded, the ultrasonic transducer is formed by grasping the lever 5b of the rotating member 5 and the protrusion 5c of the lever 5b pressing the oscillation switch 9. 2 is vibrated, and the object 17 to be welded sandwiched between the anvil 3b and the horn 2a of the ultrasonic vibrator 2 is welded. However, the time for gripping the lever 5b varies, and the pressure for gripping the lever 5b. Since it is mixed, if the lever 5b is held even after the welding is completed, the object to be welded 10 melts more than necessary, and the originally sealed part of the object to be welded 10 is not sealed. There is a problem that burns occur and defects occur in the welded portion.
Japanese Patent Application No. 2004-287756

解決しようとする問題点は、レバーを必要以上に握っていると、密閉されている部分が密閉されていなかったり、焦げが発生してりして、溶着部分に不良が発生するという問題がある。   The problem to be solved is that if the lever is gripped more than necessary, the sealed part is not sealed or the burn is generated, and the welded part is defective. .

本発明では、ハンドピースは超音波振動子を内蔵し、該超音波振動子のホーンの先端が端部に突出し、アンビル部はハンドピースの側部に摺動部材を装着し、摺動部材から突出するアンビルの接触部が超音波振動子のホーンと対向するように装着され、センサはアンビル部アンビルに装着され、回動部材はハンドピースの両側部に装着された回動軸に三角部材の頂点近傍に回動可能に装着され、三角部材からハンドピースから離れる方向にレバーを設け、突出部は回動部材のレバーの中間部に固着され、発振スイッチはハンドピースの側部に装着されて、突出部で作動され、制御装置はハンドピースに接続され、制御装置に内蔵された発振器は発振スイッチによって超音波振動子に発振出力を印加するものである。   In the present invention, the handpiece incorporates an ultrasonic transducer, the tip of the horn of the ultrasonic transducer protrudes from the end, the anvil portion has a sliding member attached to the side of the handpiece, The protruding anvil contact portion is mounted so as to face the horn of the ultrasonic transducer, the sensor is mounted on the anvil portion anvil, and the rotating member is mounted on the rotating shaft mounted on both sides of the handpiece with a triangular member. Mounted in the vicinity of the apex so as to be rotatable, a lever is provided in the direction away from the handpiece from the triangular member, the protrusion is fixed to the middle part of the lever of the rotating member, and the oscillation switch is mounted on the side of the handpiece The control device is actuated by the protrusion, the control device is connected to the handpiece, and an oscillator built in the control device applies an oscillation output to the ultrasonic transducer by an oscillation switch.

本発明の超音波溶着器は、ハンドピースに発振スイッチを装着し、アンビル部にセンサを装着し、ハンドピースに接続された制御装置に発振器及び判定回路を内蔵し、レバーを握ることにより、発振スイッチが作動され、超音波振動子に発振出力が印加され、アンビル部のアンビルと超音波振動子のホーンとの間に挟持された被溶着物が溶着され、この溶着の時に伝達される振動及び圧力をセンサで検出し、この振動と圧力の強さにより、溶着時期を判定し、発振器を停止して表示するので、常に一定した溶着を得ることができるという利点がある。   The ultrasonic welder of the present invention attaches an oscillation switch to a handpiece, attaches a sensor to an anvil part, incorporates an oscillator and a judgment circuit in a control device connected to the handpiece, and oscillates by grasping a lever. The switch is activated, the oscillation output is applied to the ultrasonic vibrator, the welding object sandwiched between the anvil of the anvil part and the horn of the ultrasonic vibrator is welded, and vibrations transmitted at the time of this welding and Since the pressure is detected by a sensor, the welding time is determined based on the vibration and the strength of the pressure, and the oscillator is stopped and displayed. Therefore, there is an advantage that a constant welding can be always obtained.

このように構成された本実施例の超音波溶着器では、ハンドピース１の側面に回動可能に装着された回動部材５のレバー５ｂをハンドピース１の方向に押し付けると、回動部材５の三角部材５ａに固着された駆動軸６でＵ字状のバネ８がバネの力に抗して押され、バネ８が戻る力によって、アンビル部３の摺動部材３ａに固着された支持軸７が押されるので、支持軸７はバネ８の戻る力によって移動され、アンビル部３の摺動部材３ａと一体となったアンビル３ｂの端部が超音波振動子２のホーン２ａの方向に移動し、又、回動部材５のレバー５ｂをハンドピース１の方向に押し付ける時に、レバー５ｂに固着された突出部５ｃによって、ハンドピース１の側部に装着された発振スイッチ１ａが押され、制御装置１２の発振器１３が作動し、発振器１３から発振出力が超音波振動子２に印加され、アンビル３ｂの端部と超音波振動子２のホーン２ａの先端との間に介在された被溶着物１０を溶着することができる。   In the ultrasonic welder of the present embodiment configured as described above, when the lever 5b of the rotating member 5 rotatably attached to the side surface of the handpiece 1 is pressed in the direction of the handpiece 1, the rotating member 5 is used. A support shaft fixed to the sliding member 3a of the anvil portion 3 by the force of the U-shaped spring 8 being pushed against the force of the spring by the drive shaft 6 fixed to the triangular member 5a. 7 is pushed, the support shaft 7 is moved by the return force of the spring 8, and the end of the anvil 3 b integrated with the sliding member 3 a of the anvil portion 3 moves in the direction of the horn 2 a of the ultrasonic transducer 2.
