【発明の詳細な説明】
〔産業上の利用分野〕
この発明はレーザ加工蒸散物の回収装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recovery device for laser processing transpiration.
炭酸ガスレーザ、ＹＡＧレーザ又はアルゴンレーザ等の
高出力レーザ光を用いて、物体の表面加工、切断或いは
人体治療のための人体表面組織の蒸散や切開等が近年盛
んに行なわれるようになった。この場合、ミラーやファ
イバを用いてレーザ光を導き、その光を最終的にレンズ
によって集光し、被照射物にレーザを照射する。BACKGROUND ART In recent years, high-power laser beams such as carbon dioxide lasers, YAG lasers, or argon lasers have been increasingly used to process and cut the surface of objects, or to evaporate and incise tissue on the surface of the human body for human body treatment. In this case, a mirror or a fiber is used to guide the laser beam, the light is finally focused by a lens, and the object to be irradiated is irradiated with the laser beam.
この場合、レンズは被照射物から通常数龍〜数ωの位置
にあるため、加工時に噴出する被照射物の蒸散物がレン
ズに付着しこれを汚すことがしばしばあった。これを避
けるために、第２図に示すように、レンズ１１の近傍に
気体噴射ノズル１２を設置し、レーザ１３の照射中はノ
ズル１２から気体を被照射物１４に向けて吹き付け、こ
れによって蒸散物を吹き飛ばす方法がとられていた。In this case, since the lens is usually located at a distance of several to several ω from the object to be irradiated, the evaporated matter of the object to be irradiated ejected during processing often adheres to the lens and stains it. In order to avoid this, a gas injection nozzle 12 is installed near the lens 11 as shown in FIG. The method used was to blow things up.
しかしながら、上記の方法では、蒸散物の飛散方向を充
分に制御できず、被照射物の表面形状によっては蒸散物
がかえってレンズ表面に付着することになる問題があっ
た。レンズ表面に蒸散物が付着すると、照射レーザのパ
ワーが低下するとともに、場合゛によってはレンズ表面
が強力なレーザによって損傷を受けることもあった。However, in the above method, the scattering direction of the evaporated matter cannot be sufficiently controlled, and depending on the surface shape of the object to be irradiated, the evaporated matter may instead adhere to the lens surface. When evaporated matter adheres to the lens surface, the power of the irradiating laser decreases, and in some cases, the lens surface may be damaged by the powerful laser.
また、レーザ照射を行なう環境によっては、蒸散物が空
中に放出されることが許されない場合もあり、このよう
な環境ではレーザ加工が行なえないこともあった。Furthermore, depending on the environment in which laser irradiation is performed, it may not be possible for evaporated substances to be released into the air, and laser processing may not be possible in such environments.
そこで、この発明は蒸散物の制御を確実に行なうことに
より、上記の問題点を解決することを目的とする。Therefore, it is an object of the present invention to solve the above problems by reliably controlling transpiration.
上記の問題点を解決するために、この発明は第１図に示
すように、レーザ照射装置の先端集光レンズ１の前方に
、レーザ２の通路を挾んで気体噴射用ノズル３と、気体
吸引用ノズル４を対向配置したものである。In order to solve the above-mentioned problems, the present invention, as shown in FIG. The nozzles 4 are arranged opposite to each other.
これらのノズル３．４は、パイプ５．６の先端に設けら
れ、空気又は適当なガスを一方のノズル３から噴出し、
他方のノズル４から吸引することにより、ノズル３．４
間に気体の層流を発生させる。レーザ２はその層流を突
き抜けて被照射物７に照射される。These nozzles 3.4 are provided at the tip of the pipe 5.6, and air or a suitable gas is ejected from one nozzle 3.
By suctioning from the other nozzle 4, nozzle 3.4
A laminar flow of gas is generated between the two. The laser 2 penetrates through the laminar flow and irradiates the object 7 to be irradiated.
上記の装置によってレーザ加工を行なうと、被照射物か
ら発生する蒸散物は、気体の層流に捕捉され、その流れ
に従って吸引側のノズル４に吸い込まれる。When laser processing is performed using the above-mentioned apparatus, the evaporated matter generated from the irradiated object is captured by the laminar flow of gas, and is sucked into the nozzle 4 on the suction side according to the flow.
なお、気体の層流の位置、即ちノズル３．４の高さは、
蒸散物の飛散状況によって設定されるが、通常は被照射
物７に極めて接近した位置に設定される。Note that the position of the laminar flow of gas, that is, the height of the nozzle 3.4, is
Although it is set depending on the scattering situation of the evaporated matter, it is usually set at a position extremely close to the object 7 to be irradiated.
この発明は以上のように、蒸散物を気体の流れによって
捕捉するものであるから、蒸散物の飛散を避けることが
できる。したがって、蒸散物がレンズに付着することが
防止されるとともに、レンズの頻繁なりリーニングを行
なう必要がなく、使い易いレーザ加工装置となる。As described above, since the present invention traps transpired substances by the gas flow, it is possible to avoid scattering of transpired substances. Therefore, transpiration is prevented from adhering to the lens, and there is no need for frequent cleaning of the lens, resulting in an easy-to-use laser processing apparatus.
また、空中に蒸散物が飛散することがないため、クリー
ンな環境においてもレーザ加工、レーザ治療等を行なう
ことができる。Further, since no evaporated substances are scattered in the air, laser processing, laser treatment, etc. can be performed even in a clean environment.
