Description

この発明は、光学素子を収容した光学パッケージに集光用のレンズを取り付けて一体化した光学パッケージと、一体化するための接合方法に関するものである。   The present invention relates to an optical package in which a condensing lens is attached to and integrated with an optical package containing an optical element, and a bonding method for integration.

光学素子を収容した光学パッケージにレンズを取り付ける場合、光学素子の光軸とレンズの光軸とを一致させる必要がある。そこで、例えば特許文献1に開示された光学パッケージの製造方法では、光学素子を収容した光学パッケージの外周に位置決め用の組立て段差を設けて、そこへレンズを取り付けるようにして光軸合わせをしていた。   When a lens is attached to an optical package that houses an optical element, it is necessary to match the optical axis of the optical element with the optical axis of the lens. Thus, for example, in the method for manufacturing an optical package disclosed in Patent Document 1, an assembly step for positioning is provided on the outer periphery of the optical package containing the optical element, and the optical axis is aligned by attaching a lens there. It was.

他方、光学素子の光軸とレンズの光軸を合わせる調芯方法として、従来、カメラにより光学素子とレンズを撮像して、光学素子の外形中心とレンズの外形中心を合わせる方法がある。この調芯方法を図7に示す。図において、光学パッケージ1は、光学素子3と基板6とをモールド部2により固定し、その上から透光性の樹脂により封止してなる。光学パッケージ1の接合面5にレンズ10を取り付ける際、調芯装置20が、カメラ21で光学パッケージ1とレンズ10とを正面から撮像し、撮像画像より光学素子3の外形とレンズ10の外形を認識して、光学素子3の外形中心X3とレンズ10の外形中心X10を求め、調芯する。   On the other hand, as a method of aligning the optical axis of the optical element and the optical axis of the lens, there is a conventional method of imaging the optical element and the lens with a camera and aligning the outer center of the optical element with the outer center of the lens. This alignment method is shown in FIG. In the figure, an optical package 1 is formed by fixing an optical element 3 and a substrate 6 with a mold part 2 and sealing with a translucent resin from above. When the lens 10 is attached to the joint surface 5 of the optical package 1, the alignment device 20 images the optical package 1 and the lens 10 from the front with the camera 21, and the outer shape of the optical element 3 and the outer shape of the lens 10 are taken from the captured image. Recognizing, the external center X3 of the optical element 3 and the external center X10 of the lens 10 are obtained and aligned.

特開2006−339653号公報JP 2006-339653 A

特許文献1に係る製造方法では、光学パッケージ自体の大きさがレンズ側面の厚み分だけ大きくなってしまうという課題があり、光学パッケージを実装する回路基板上に大きな設置面積を要求するようになるので好ましくない。   In the manufacturing method according to Patent Document 1, there is a problem that the size of the optical package itself is increased by the thickness of the side surface of the lens, and a large installation area is required on the circuit board on which the optical package is mounted. It is not preferable.

他方、図7に示す調芯方法では、カメラの撮像画像はレンズによる屈折の影響を受けるものとなるため、この影響を排除するための調整が困難になるという課題がある。
また、光学パッケージに取り付けるレンズは、図7のレンズ10のように片面が平面、もう片面が曲面の構成の他、図8に示すようにレンズ部31とプリズム部32とが一体的に形成された構成のプリズムレンズ30の場合もある。プリズムレンズ30の場合、図8のモニタ画面22に表示されたカメラ21の撮像画像にも示すとおり、光学素子3の外形とレンズ部31の外形を同時に認識できない。このため、別途、カメラ23をレンズ部31の正面方向に設置してレンズ部31の外形を認識し、その外形中心X31を求める必要があるが、そうすると調芯装置20が複雑化し、高価なものとなってしまう。また、調芯手順もより多く複雑になってしまう。
On the other hand, the alignment method shown in FIG. 7 has a problem that an image captured by the camera is affected by refraction by the lens, and adjustment for eliminating this influence becomes difficult.
The lens attached to the optical package has a structure in which one side is flat like the lens 10 in FIG. 7 and the other side is curved, and a lens part 31 and a prism part 32 are integrally formed as shown in FIG. In some cases, the prism lens 30 may have a different configuration. In the case of the prism lens 30, the outer shape of the optical element 3 and the outer shape of the lens unit 31 cannot be recognized at the same time as shown in the captured image of the camera 21 displayed on the monitor screen 22 of FIG. For this reason, it is necessary to separately install the camera 23 in the front direction of the lens unit 31 to recognize the outer shape of the lens unit 31 and obtain the outer center X31. However, the alignment device 20 becomes complicated and expensive. End up. Also, the alignment procedure becomes more complicated.

この発明は、上記のような課題を解決するためになされたもので、レンズと光学素子の光軸合わせが簡易かつ正確にできる光学パッケージ、及び光学パッケージとレンズの接合方法を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide an optical package capable of easily and accurately aligning the optical axis of a lens and an optical element, and a method for joining the optical package and the lens. And

The positioning concave portion is provided on the joint surface of the optical package, the outer center is aligned with the optical axis of the optical element, and the positioning convex portion is provided on the joint surface of the lens, and The outer shape center is aligned with the optical axis of the lens .

この発明の請求項に係る光学パッケージは、位置決め用凸部を光学フィルタにしたものである。 According to a second aspect of the present invention, the positioning convex portion is an optical filter.

この発明の請求項に係る光学パッケージは、レンズが、集光用の曲面と、光学パッケージに接合する接合面と、当該曲面と当該接合面の間を通る光束を任意角度に折り曲げる屈折部とを有するようにしたものである。 In the optical package according to claim 3 of the present invention, the lens includes a curved surface for condensing, a joint surface joined to the optical package, and a refracting portion that bends the light flux passing between the curved surface and the joint surface to an arbitrary angle. It is made to have.

この発明の請求項1から請求項によれば、光学パッケージとレンズの接合面に、光学素子とレンズの光軸を位置合わせするための位置決め用凹凸部を設けるようにしたので、光学パッケージとレンズの接合時に位置決め用凹凸部を嵌合することで光軸合わせが簡易かつ正確にできる光学パッケージを提供することができる。 According to the first and second aspects of the present invention, the positioning concave and convex portions for aligning the optical axes of the optical element and the lens are provided on the joint surface between the optical package and the lens. An optical package capable of easily and accurately aligning the optical axis can be provided by fitting the concave and convex portions for positioning when the lenses are joined.

この発明の請求項によれば、レンズが、曲面と接合面の間を通る光束を任意角度に折り曲げる屈折部を有するようにしたので、プリズムレンズであっても光学素子との光軸合わせを簡易かつ正確に行うことができる。 According to the third aspect of the present invention, since the lens has a refracting portion that bends the light beam passing between the curved surface and the joint surface at an arbitrary angle, the optical axis alignment with the optical element can be performed even with a prism lens. It can be done easily and accurately.

実施の形態1.
図1及び図2は、この発明の実施の形態1に係る光学パッケージ1の構成を示す側面図である。なお、本実施の形態1で用いる光学パッケージ1は、先立って説明した図8の光学パッケージ1と同様に、光学素子3を基板6の上にモールド部2により固定し、透光性の樹脂により封止してなる。光学素子3には受光素子、投光素子(例えばLight Emitting Diode)等を用いる。なお、図示例は概略図であり、光学素子3と基板6とを接続するワイヤ等の詳細は図示を省略する。
Embodiment 1 FIG.
1 and 2 are side views showing the configuration of the optical package 1 according to Embodiment 1 of the present invention. In the optical package 1 used in the first embodiment, the optical element 3 is fixed on the substrate 6 by the mold part 2 and is made of a translucent resin, as in the optical package 1 shown in FIG. It is sealed. As the optical element 3, a light receiving element, a light projecting element (for example, Light Emitting Diode) or the like is used. Note that the illustrated example is a schematic diagram, and details of wires and the like that connect the optical element 3 and the substrate 6 are omitted.

この光学パッケージ1にプリズムレンズ30を接合して一体化するために、位置決め用凸部40及び位置決め用凹部41を、新たに設ける。
位置決め用凸部40は、光学パッケージ1の接合面5に設ける。位置決め用凸部40として、好ましくは、調芯装置20で認識できる光波長を透過させる材質、かつ、光学パッケージ1に取り付けるプリズムレンズ30と屈折率が近い材質を用いる。例えば、透明フィルム、樹脂成形品等とする。位置決め用凸部40の形状は、モニタ画面22に表示しているような円形でもよいし、その他、例えば角形でもよい。
また、図示例では直方体の光学パッケージ1及び光学素子3を示したが、形状はこれに限定されるものではなく、外形から光学素子3の中心位置を求めることができる形状であればよい。ここでは、求めた外形中心X3を光学素子3の光軸とみなす。
In order to join and integrate the prism lens 30 to the optical package 1, a positioning convex portion 40 and a positioning concave portion 41 are newly provided.
The positioning convex portion 40 is provided on the bonding surface 5 of the optical package 1. The positioning convex portion 40 is preferably made of a material that transmits a light wavelength that can be recognized by the alignment device 20 and a material that has a refractive index close to that of the prism lens 30 that is attached to the optical package 1. For example, a transparent film, a resin molded product, or the like is used. The shape of the positioning convex portion 40 may be a circle as displayed on the monitor screen 22, or may be a square, for example.
Moreover, although the rectangular parallelepiped optical package 1 and the optical element 3 are shown in the illustrated example, the shape is not limited to this, and any shape may be used as long as the center position of the optical element 3 can be obtained from the outer shape. Here, the obtained outer center X3 is regarded as the optical axis of the optical element 3.

この位置決め用凸部40は、従来の調芯装置20を用いて位置決め用凸部40の外形中心X40を光学素子3の外形中心X3と位置合わせ(調芯)し、接着剤、レーザ溶着等により接着する。なお、光学パッケージ1を光電センサ等に組み込んで使用する場合には、その使用目的に応じた材質の接着剤を用いることとする。例えば、光学パッケージ1を光電センサの投光用に利用するなら、接着剤は、検出用の光波長を透過する材質にする。   The positioning convex portion 40 aligns (aligns) the outer shape center X40 of the positioning convex portion 40 with the outer shape center X3 of the optical element 3 using the conventional aligning device 20, and uses an adhesive, laser welding, or the like. Glue. When the optical package 1 is used by being incorporated in a photoelectric sensor or the like, an adhesive made of a material corresponding to the purpose of use is used. For example, when the optical package 1 is used for light projection of a photoelectric sensor, the adhesive is made of a material that transmits a light wavelength for detection.

また、位置決め用凹部41を、プリズムレンズ30の接合面34に設ける。図2に示すように、この位置決め用凹部41は、位置決め用凸部40より嵌め合い程度大きくする。位置決め用凹部41は、例えば、透明樹脂を金型で成形してプリズムレンズ30を作成する際に同時に成形すればよい。   Further, the positioning concave portion 41 is provided on the joint surface 34 of the prism lens 30. As shown in FIG. 2, the positioning concave portion 41 is larger than the positioning convex portion 40 so as to be fitted. The positioning recess 41 may be formed at the same time when the prism lens 30 is formed by forming a transparent resin with a mold, for example.

図3に、プリズムレンズ30を接合して一体化した光学パッケージ1の構成を示す。光学素子3の外形中心X3に調芯した位置決め用凸部40に位置決め用凹部41を嵌め込むことで、光学素子3とプリズムレンズ30の調芯精度を容易に確保できる。位置決め用凸部40と位置決め用凹部41の嵌合は、圧入による圧入固定でもよいし、接着剤等を用いた接着固定でもよい。ただし、接着剤は、上述の通り、光学パッケージ1の用途に応じて材質を選定する必要がある。また、透光性を保つため、位置決め用凸部40と位置決め用凹部41の各当接面には接着材等の固定手段を設けない方が望ましい。従って、接着剤等の固定手段を用いて固定する場合には、接着剤を接合面5のみに塗布するようにして、位置決め用凸部40の上面及び位置決め用凹部41の底面には塗布しないようにすることが望ましい。   FIG. 3 shows a configuration of the optical package 1 in which the prism lens 30 is joined and integrated. By fitting the positioning concave portion 41 into the positioning convex portion 40 aligned with the outer shape center X3 of the optical element 3, the alignment accuracy of the optical element 3 and the prism lens 30 can be easily secured. The fitting between the positioning convex portion 40 and the positioning concave portion 41 may be press-fitting by press-fitting or adhesive fixing using an adhesive or the like. However, it is necessary to select the material of the adhesive according to the use of the optical package 1 as described above. In order to maintain translucency, it is desirable not to provide fixing means such as an adhesive on the contact surfaces of the positioning convex portion 40 and the positioning concave portion 41. Therefore, when fixing using a fixing means such as an adhesive, the adhesive is applied only to the bonding surface 5 and not applied to the top surface of the positioning convex portion 40 and the bottom surface of the positioning concave portion 41. It is desirable to make it.

また、光学素子3の外形中心X3とレンズ部31の外形中心X31との位置決め精度を高めるためには、予め位置決め用凸部40の外形中心X40を光学素子3の外形中心X3に相当する位置に調芯しておくとともに、位置決め用凹部41の外形中心を、レンズ部31の外形中心X31に相当する位置に調芯しておく。そのうえで上述したとおり位置決め用凸部40に位置決め用凹部41を嵌め込むことで両者の外形中心を精度良く位置決めできるので、ひいては光学素子3の外形中心X3とレンズ部31の外形中心X31との位置決め精度を向上させることが可能となる。   Further, in order to increase the positioning accuracy between the outer shape center X3 of the optical element 3 and the outer shape center X31 of the lens portion 31, the outer shape center X40 of the positioning convex portion 40 is set in advance to a position corresponding to the outer shape center X3 of the optical element 3. While aligning, the outer center of the positioning recess 41 is aligned to a position corresponding to the outer center X31 of the lens unit 31. In addition, since the positioning concave portion 41 is fitted into the positioning convex portion 40 as described above, the center of the outer shape of both can be accurately positioned. As a result, the positioning accuracy between the outer shape center X3 of the optical element 3 and the outer shape center X31 of the lens portion 31 is improved. Can be improved.

以上より、実施の形態1によれば、光学素子3を収容した光学パッケージ1と、集光用のレンズ部31と屈折用のプリズム部32とを有し、光学パッケージ1に接合されて一体化するプリズムレンズ30と、光学素子3とプリズムレンズ30の光軸を位置合わせするための、光学パッケージ1の接合面5とプリズムレンズ30の接合面34に設けた位置決め用凸部40及び位置決め用凹部41とを備えるように構成した。このため、位置決め用凸部40と位置決め用凹部41を嵌合させながら光学パッケージ1とプリズムレンズ30とを接合すれば、光学素子3とプリズムレンズ30の調芯ができるので、調芯が容易になる。さらに、従来のようにプリズムレンズ30のレンズ部31を介して光学素子3をカメラ21で撮像する工程を含まず、また、位置決め用凸部40と位置決め用凹部41を嵌合すれば調芯できるので、調芯が正確にできる。   As described above, according to the first embodiment, the optical package 1 containing the optical element 3, the condensing lens portion 31, and the refraction prism portion 32 are joined and integrated with the optical package 1. The positioning convex portion 40 and the positioning concave portion provided on the joint surface 5 of the optical package 1 and the joint surface 34 of the prism lens 30 for aligning the optical axes of the prism lens 30, the optical element 3 and the prism lens 30. 41. For this reason, if the optical package 1 and the prism lens 30 are joined while the positioning convex portion 40 and the positioning concave portion 41 are fitted, the optical element 3 and the prism lens 30 can be aligned, so that alignment is easy. Become. Further, it does not include a step of imaging the optical element 3 with the camera 21 via the lens portion 31 of the prism lens 30 as in the conventional case, and can be aligned by fitting the positioning convex portion 40 and the positioning concave portion 41. Therefore, alignment can be performed accurately.

なお、図1〜図3に例示したプリズムレンズ30は、曲面33と接合面34の間を通る光束の光軸を、プリズム部(屈折部)32の反射面で90度折り曲げる構成であるが、これに限定されるものではなく、プリズムレンズとして、図4(a),(b)に示すプリズムレンズ30のような光軸を任意の角度に折り曲げる構成のものを用いることもできる。
また、図1〜図4では、プリズムレンズ30の接合面34の外形が光学パッケージ1の接合面5の外形より小さい例を示したが、反対に接合面34の外形が接合面5の外形より大きくてもよいし、あるいは同じでも構わないことは言うまでもない。
The prism lens 30 illustrated in FIGS. 1 to 3 is configured to bend the optical axis of the light beam passing between the curved surface 33 and the joint surface 34 by 90 degrees on the reflecting surface of the prism portion (refractive portion) 32. However, the present invention is not limited to this, and a prism lens having a configuration that bends the optical axis to an arbitrary angle such as the prism lens 30 shown in FIGS. 4A and 4B can also be used.
1 to 4 show an example in which the outer shape of the joint surface 34 of the prism lens 30 is smaller than the outer shape of the joint surface 5 of the optical package 1. It goes without saying that it can be large or the same.

実施の形態2.
上記実施の形態1では、光学パッケージ1に位置決め用凸部40を設け、プリズムレンズ30に位置決め用凹部41を設けたが、反対に、光学パッケージ1に位置決め用凹部41を設け、プリズムレンズ30に位置決め用凸部40を設ける構成であってもよい。一例を図5に示す。位置決め用凹部41を凹設した位置決め用部材42を、光学素子3の外形中心X3に調芯して接合面5に接着すると共に、位置決め用凸部40を、レンズ部31の外形中心X31に調芯して接合面34に接着し、位置決め用凸部40と位置決め用凹部41を嵌合させながら光学パッケージ1とプリズムレンズ30とを接合する。位置決め用部材42としては透明フィルム、又は絞りの機能を併せ持たせるために黒色の遮光材等を用いることができる。
なお、図示例では位置決め用部材42を別途用意して位置決め用凹部41を凹設したが、接合面5に位置決め用凹部41を直接凹設してもよい。
Embodiment 2. FIG.
In the first embodiment, the positioning convex portion 40 is provided in the optical package 1 and the positioning concave portion 41 is provided in the prism lens 30. On the contrary, the positioning concave portion 41 is provided in the optical package 1 and the prism lens 30 is provided. The structure which provides the convex part 40 for positioning may be sufficient. An example is shown in FIG. The positioning member 42 provided with the positioning concave portion 41 is aligned with the outer center X3 of the optical element 3 and adhered to the joint surface 5, and the positioning convex portion 40 is adjusted to the outer center X31 of the lens unit 31. The optical package 1 and the prism lens 30 are bonded together while the positioning convex portion 40 and the positioning concave portion 41 are fitted together. As the positioning member 42, a transparent film or a black light shielding material or the like can be used in order to have a function of a diaphragm.
In the illustrated example, the positioning member 42 is separately prepared and the positioning recess 41 is provided. However, the positioning recess 41 may be provided directly on the joining surface 5.

以上より、実施の形態2によれば、位置決め用凸部40をプリズムレンズ30の接合面34に設け、位置決め用凹部41を光学パッケージ1の接合面5に設ける構成にしても、上記実施の形態1と同様に、簡易かつ正確に調芯できる。   As described above, according to the second embodiment, the positioning convex portion 40 is provided on the joint surface 34 of the prism lens 30 and the positioning concave portion 41 is provided on the joint surface 5 of the optical package 1. As in 1, it can be easily and accurately aligned.

なお、上記実施の形態1,2では、プリズムレンズ30を光学パッケージ1に取り付ける場合を例に説明したが、取り付けるレンズの種類はこれに限定されるものではなく、例えば図6に示すような片面に曲面11を、他方の面に接合面12を形成したレンズ10であってもよい。図6の場合、光学パッケージ1の接合面5に位置決め用凸部40を形成し、レンズ10の接合面12に位置決め用凹部41を形成する。あるいは、接合面5に位置決め用凹部41を形成し、接合面12に位置決め用凸部40を形成してもよい。   In the first and second embodiments, the case where the prism lens 30 is attached to the optical package 1 has been described as an example. However, the type of lens to be attached is not limited to this, and for example, one side as shown in FIG. Alternatively, the lens 10 may have a curved surface 11 and a cemented surface 12 formed on the other surface. In the case of FIG. 6, the positioning convex portion 40 is formed on the joint surface 5 of the optical package 1, and the positioning concave portion 41 is formed on the joint surface 12 of the lens 10. Alternatively, the positioning concave portion 41 may be formed on the bonding surface 5 and the positioning convex portion 40 may be formed on the bonding surface 12.

また、位置決め用凸部40を光学フィルタを用いて構成してもよい。光学フィルタとしては、偏光フィルタ、波長フィルタ(カラーフィルタ、赤外フィルタ等)を用いることができる。これらを用いて位置決め用凸部40を構成することで、従来は光路上に別途光学フィルタを設けなければならなかったのに対し、光学パッケージ1と光学フィルタとを一体に取り扱うことができるので、組立の容易性が向上する。   Moreover, you may comprise the convex part 40 for positioning using an optical filter. As the optical filter, a polarizing filter and a wavelength filter (color filter, infrared filter, etc.) can be used. By configuring the positioning convex portion 40 using these, the optical package 1 and the optical filter can be handled integrally, whereas conventionally, an optical filter must be separately provided on the optical path. The ease of assembly is improved.
