Description
【０００１】[0001]
本考案は、リードフレームのリード、タブテープのリード等を検出するリード 検出装置に関する。 The present invention relates to a lead detection device for detecting leads of lead frames, tab tape leads, and the like.
【０００２】[0002]
従来、リード検出装置として、例えば特開平１ー２０６６３８号公報に示すも のが知られている。この装置は、図２に示すように、タブテープ又はリードフレ ーム１に形成された被検出物であるリード２の上方に検出用カメラ３が配置され 、この検出用カメラ３の下端に落射照明手段４が取付けらえている。落射照明手 段４は、ハーフミラー５を有する鏡筒６と、この鏡筒６の側方に取付けられた照 明７とからなっている。またリード２の下方には、鏡面よりなる反射鏡８が配置 されている。 Conventionally, as a lead detecting device, for example, the one shown in Japanese Patent Laid-Open No. 1-206638 is known. In this device, as shown in FIG. 2, a detection camera 3 is arranged above a lead 2 which is an object to be detected formed on a tab tape or a lead frame 1, and an epi-illumination means is provided at a lower end of the detection camera 3. 4 is installed. The epi-illumination device 4 includes a lens barrel 6 having a half mirror 5 and an illumination 7 mounted on the side of the lens barrel 6. Below the lead 2, a reflecting mirror 8 having a mirror surface is arranged.
【０００３】[0003]
上記従来技術は、鏡面反射鏡を用いているので、入射光９の角度と同じ角度で 反射光１０は反射する。このため、図３に示すように反射鏡８が傾くと、反射光 １０は入射光９と反射角がずれ、検出用カメラ３にリード２の像が入ってこない 。そこで、鏡筒６と反射鏡８との光軸合わせをする必要があった。またこの光軸 合わせ誤差により、検出範囲内での光量のバラツキが発生するという問題があっ た。 Since the above-mentioned conventional technique uses the specular reflecting mirror, the reflected light 10 is reflected at the same angle as the incident light 9. Therefore, when the reflecting mirror 8 is tilted as shown in FIG. 3, the reflected light 10 has a different reflection angle from the incident light 9, and the image of the lead 2 does not enter the detection camera 3. Therefore, it is necessary to align the optical axes of the lens barrel 6 and the reflecting mirror 8. In addition, there was a problem that variations in the amount of light within the detection range occur due to this optical axis alignment error.
【０００４】 本考案の目的は、光軸合わせが不要であると共に、検出範囲内での光量のバラ ツキがないリード検出装置を提供することにある。An object of the present invention is to provide a lead detection device that does not require optical axis alignment and has no variation in the amount of light within the detection range.
【０００５】[0005]
上記目的を達成するための本考案の構成は、被検出物の一方側に照明手段と検 出用カメラとを配置し、被検出物の他方側に反射鏡を配置したリード検出装置に おいて、前記反射鏡は再帰性反射鏡よりなることを特徴とする。 The configuration of the present invention for achieving the above object is a lead detection apparatus in which an illuminating means and a detection camera are arranged on one side of an object to be detected and a reflecting mirror is arranged on the other side of the object to be detected. The reflecting mirror is a retroreflecting mirror.
【０００６】[0006]
このように、再帰性反射鏡を用いるので、入射光の入射角に対して反射光の反 射角が同一方向に戻る。このため、光軸合わせが不要となり、また検出範囲内で の光量のバラツキがなく、検出効率が向上する。 Since the retroreflecting mirror is used in this way, the reflection angle of the reflected light returns to the same direction with respect to the incident angle of the incident light. Therefore, alignment of the optical axis becomes unnecessary, and there is no variation in the amount of light within the detection range, which improves the detection efficiency.
【０００７】[0007]
以下、本考案の一実施例を図１により説明する。なお、図２と同じ部材には同 一符号を付し、その説明は省略する。リード２の上方に落射照明手段４が設けら れ、リード２の下方に再帰性反射鏡１５が配置されている。再帰性反射鏡１５は 、反射シートの素材を使用したもので、スリーエム（３Ｍ）社等で販売されてい る。 An embodiment of the present invention will be described below with reference to FIG. The same members as those in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted. An epi-illumination means 4 is provided above the lead 2, and a retroreflecting mirror 15 is provided below the lead 2. The retroreflective mirror 15 is made of a material of a reflective sheet, and is sold by 3M (3M) Company.
【０００８】 このように、再帰性反射鏡１５を用いるので、入射光９の入射角に対して反射 光１０の反射角が同一方向に戻る。このため、光軸合わせが不要となり、また検 出範囲内での光量のバラツキがなく、検出効率が向上する。なお、上記実施例は 、落射照明手段４としてハーフミラー照明を用いたが、ＬＥＤ（発光ダイオード ）をリング状に多数配置した照明手段を用いてもよい。As described above, since the retroreflecting mirror 15 is used, the reflection angle of the reflected light 10 returns to the same direction with respect to the incident angle of the incident light 9. Therefore, alignment of the optical axis is not necessary, and there is no variation in the amount of light within the detection range, improving detection efficiency. Although half mirror illumination is used as the epi-illumination means 4 in the above embodiment, an illumination means in which a large number of LEDs (light emitting diodes) are arranged in a ring shape may be used.
【０００９】[0009]
本考案によれば、被検出物の一方側に照明手段と検出用カメラとを配置し、被 検出物の他方側に反射鏡を配置したリード検出装置において、前記反射鏡は再帰 性反射鏡よりなるので、光軸合わせが不要となり、また検出範囲内での光量のバ ラツキがなく、検出効率が向上する。 According to the present invention, in the lead detection device in which the illuminating means and the detection camera are arranged on one side of the object to be detected, and the reflecting mirror is arranged on the other side of the object to be detected, the reflecting mirror is more than a retroreflecting mirror. As a result, the optical axis alignment is not necessary, and there is no variation in the amount of light within the detection range, improving detection efficiency.
