Description

本発明は、いわゆるビューカメラやセンサカメラ等の車載カメラに好適であり、カメラ付き携帯電話やカメラ付きノートパソコン等にも利用可能なカメラモジュールに関し、それらカメラモジュールにおいてレンズ部材を焦点位置を調整しつつ簡易な工程で取り付けることができるレンズ部材の取付方法に関するものである。   The present invention relates to a camera module that is suitable for an on-vehicle camera such as a so-called view camera or a sensor camera, and can be used for a camera-equipped mobile phone, a camera-equipped laptop computer, and the like. However, the present invention relates to a method of attaching a lens member that can be attached by a simple process.

カメラ付き携帯電話やカメラ付きノートパソコンに組み込まれる小型オンボードカメラをはじめとして、いわゆるビューカメラやセンサカメラ等の車載カメラとして用いられるカメラモジュールは、いずれも小型で低コストでありながら精度が高く耐久性にも優れていることが要求されている。特に、撮像素子とともにカメラモジュールの主要な構成部材であるレンズ部材には、レンズを安定して保持しつつ撮像素子に対する焦点合わせを精度よく行なって、できるだけ簡易な工程で取り付けてカメラモジュールを構成することが要求されている。   Camera modules used as in-vehicle cameras such as so-called view cameras and sensor cameras, as well as small on-board cameras built into camera-equipped mobile phones and camera-equipped laptops, are both compact and low-cost, yet highly accurate and durable. It is required to have excellent properties. In particular, the lens member, which is a main component of the camera module together with the image sensor, is configured to focus on the image sensor with high accuracy while stably holding the lens, and is attached in as simple a process as possible to constitute the camera module. It is requested.

これに対し、レンズ部材としてレンズを保持する円筒状の部材であるバレルとバレルを保持する円筒状の部材であるバレルホルダとを用いて、このバレルホルダをカメラモジュールの筐体の一部としておいて、それに対してバレルの位置を軸方向に摺動して調整することによって、レンズが対向する撮像素子に対してレンズの焦点合わせを行ない、その後にバレルの外周面をバレルホルダの内周面に接着する、あるいはバレルの外周面をバレルホルダの内周面にレーザ溶着により溶着することによって固定して、レンズ部材をカメラモジュールに取り付けることが行なわれている。   On the other hand, using a barrel that is a cylindrical member that holds a lens as a lens member and a barrel holder that is a cylindrical member that holds the barrel, the barrel holder is a part of the housing of the camera module, On the other hand, by adjusting the position of the barrel by sliding in the axial direction, the lens is focused on the imaging element facing the lens, and then the outer peripheral surface of the barrel is bonded to the inner peripheral surface of the barrel holder. Alternatively, the lens member is attached to the camera module by fixing the outer peripheral surface of the barrel to the inner peripheral surface of the barrel holder by laser welding.

また、例えば特許文献１には、カメラモジュールの製造方法として、内周部にレンズを有し外周部にネジ部が形成された内側鏡筒部を、内周部に内側鏡筒部のネジ部に螺合するネジ部を有する外側鏡筒部に螺合させ、内側鏡筒部と外側鏡筒部のうちの一方に対する他方の繰り出し量を調整し、内側鏡筒部のネジ部と外側鏡筒部のネジ部との合わせ目にレーザ光を照射して内側鏡筒部のネジ部と外側鏡筒部のネジ部との合わせ目の少なくとも一方の面を繰り出し量の方向に0.5ｍｍ以上で３ｍｍ以下溶融させて硬化させる製造方法が開示されている。この特許文献１に開示されたカメラモジュールの製造方法によれば、内側鏡筒部と外側鏡筒部とを溶着固定することによって、大きな固定強度を得ることができるというものである。
特開2006−106517号公報 Further, for example, in Patent Document 1, as a method of manufacturing a camera module, an inner barrel portion having a lens on an inner peripheral portion and a screw portion formed on the outer peripheral portion is provided, and a screw portion of the inner barrel portion is provided on the inner peripheral portion. Screwed into the outer barrel portion having a screw portion to be screwed into the inner barrel portion and adjusted the other feed amount with respect to one of the inner barrel portion and the outer barrel portion, the screw portion of the inner barrel portion and the outer barrel At least one surface of the joint of the screw part of the inner lens barrel part and the screw part of the outer lens barrel part is irradiated with laser light at the joint with the screw part of the inner part and 0.5 mm or more in the direction of the feeding amount. A manufacturing method for melting and curing is disclosed below. According to the camera module manufacturing method disclosed in Patent Document 1, a large fixing strength can be obtained by welding and fixing the inner lens barrel portion and the outer lens barrel portion.
JP 2006-106517 A

しかしながら、いずれも円筒状の部材であるバレルとバレルホルダとを摺動させてレンズの焦点合わせを行なってから固定する方法では、バレルの摺動面とバレルホルダの摺動面との間には、摺動させるために少なからず間隔が必要なために隙間が生じてしまう。ところが、両者を固定するのに、硬化時間が必要な接着剤を用いた接着ではなく瞬時に固定できるレーザ溶着を行なおうとすると、レーザ溶着の場合には溶着する面同士をある程度の圧力をかけて密着させておく必要があるため、バレルとバレルホルダとの間に隙間が生じているために良好な溶着ができないか、または溶着できても全周で一様に十分な強度を得ることが難しいという問題点があった。   However, in both methods, the barrel and the barrel holder, which are cylindrical members, are slid to focus the lens and then fixed, the sliding surface between the barrel sliding surface and the barrel holder sliding surface is not provided. A gap is generated because an interval is required for the movement. However, when laser welding that can be fixed instantaneously rather than using an adhesive that requires a curing time to fix the two is performed, a certain amount of pressure is applied between the surfaces to be welded in the case of laser welding. Since there is a gap between the barrel and the barrel holder, good welding cannot be performed, or even if welding is possible, it is difficult to obtain sufficient strength uniformly throughout the circumference. There was a problem.

また、特許文献１に開示されたカメラモジュールの製造方法では、バレルに相当する内側鏡筒部のネジ部とバレルホルダに相当する外側鏡筒部のネジ部との合わせ目にレーザ光を照射する際に、この溶着しようとする合わせ目においても対向する面同士に十分な圧力がかかった状態とは言えないため、やはり全周で一様に十分な強度で溶着することが難しいという問題点があった。また、ネジ部の合わせ目を溶着することから、カメラモジュールが小型化してネジ部も小さくなっていく中では、十分な溶着面積を確保することが難しいという問題点もあった。   In the method for manufacturing a camera module disclosed in Patent Document 1, laser light is irradiated at the joint between the screw portion of the inner barrel portion corresponding to the barrel and the screw portion of the outer barrel portion corresponding to the barrel holder. In addition, the seam to be welded cannot be said to be in a state in which sufficient pressure is applied between the opposing surfaces, so that it is difficult to weld with sufficient strength uniformly over the entire circumference. It was. Further, since the joints of the screw portions are welded, there is a problem that it is difficult to secure a sufficient welding area while the camera module is downsized and the screw portions are also reduced.

本発明は以上のような従来の技術における問題点に鑑みて案出されたものであり、その目的は、円筒状のバレルにレンズが装着されてなるレンズ部材をバレルホルダが設けられたケース部材に、焦点合わせを行なってレーザ溶着により十分な強度で良好に取り付けることができる、カメラモジュールにおけるレンズ部材の取付方法を提供することにある。   The present invention has been devised in view of the problems in the prior art as described above, and an object thereof is to replace a lens member in which a lens is mounted on a cylindrical barrel with a case member provided with a barrel holder.

本発明の第１のカメラモジュールにおけるレンズ部材の取付方法によれば、上記構成により、ケース部材のバレルホルダに取り付けられる円筒状のバレルにレンズが装着されてなるレンズ部材を準備し、レンズ部材をバレルホルダに挿入し、レンズ部材をレンズの光軸方向に動かして、カメラモジュールの撮像面にレンズの焦点を合わせて、次に、バレルの外側面に上記クサビリングをはめ込んで、このクサビリングの内周面をバレルの外側面に当接させるとともにクサビリングの外周傾斜面をバレルホルダの傾斜面に当接させ、しかる後、クサビリングの外周傾斜面に当接しているバレルホルダの傾斜面およびクサビリングの内周面に当接しているバレルの外側面にレーザを照射して、クサビリングをバレルホルダおよびバレルに溶着して、レンズ部材をケース部材に取り付けることから、レンズ部材のバレルとケース部材のバレルホルダとの間にはレンズ部材をレンズの光軸方向に動かせる隙間を確保しつつ、焦点を合わせてレンズ部材を位置決めした後には、クサビリングによってバレルの外側面とバレルホルダの傾斜面との間隔を埋めるとともに、バレルの外側面とクサビリングの内周面との間およびバレルホルダの傾斜面とクサビリングの外周傾斜面との間の両方に一様な圧力をかけながらレーザ溶着を行なうことができるので、焦点合わせを行なった状態で安定して良好なレーザ溶着が可能となり、十分な強度でレンズ部材のバレルをケース部材のバレルホルダに取り付けることが可能となる。また、クサビリングの内周面とバレルの外側面との間およびクサビリングの外周傾斜面とバレルホルダの傾斜面との間でレーザ溶着を行なうことから十分な溶着面積を確保することができるので、十分な強度でレンズ部材のバレルをケース部材のバレルホルダに良好に取り付けることが可能となる。   According to the method of attaching the lens member in the first camera module of the present invention, the lens member is prepared by mounting the lens on the cylindrical barrel attached to the barrel holder of the case member, and the lens member is attached to the barrel holder. The lens member is moved in the optical axis direction of the lens so that the lens is focused on the imaging surface of the camera module, and then the above-mentioned wedge ring is fitted on the outer side surface of the barrel.

Laser is applied to the outer surface of the barrel that is in contact with the inner peripheral surface of the barrel, and the wedge ring is welded to the barrel holder and barrel. Since the lens member is attached to the case member, after the lens member is positioned in focus while securing a gap that allows the lens member to move in the optical axis direction of the lens between the barrel of the lens member and the barrel holder of the case member The wedge ring fills the gap between the outer surface of the barrel and the inclined surface of the barrel holder, and between the outer surface of the barrel and the inner peripheral surface of the wedge ring and between the inclined surface of the barrel holder and the outer peripheral inclined surface of the wedge ring. Since laser welding can be performed while applying a uniform pressure to both, it is possible to stably and satisfactorily perform laser welding in a focused state, and the barrel of the lens member can be secured to the barrel holder of the case member with sufficient strength. It becomes possible to attach to. In addition, since laser welding is performed between the inner peripheral surface of the wedge ring and the outer peripheral surface of the barrel and between the outer peripheral inclined surface of the wedge ring and the inclined surface of the barrel holder, a sufficient welding area can be secured. It is possible to satisfactorily attach the barrel of the lens member to the barrel holder of the case member with sufficient strength.

The lens is focused on the image pickup surface, and then the laser is irradiated to the inclined surface of the barrel holder that is in contact with the outer peripheral inclined surface of the wedge ring and the outer surface of the barrel that is in contact with the inner peripheral surface of the wedge ring. Since the wedge ring is welded to the barrel holder and the barrel and the lens member is attached to the case member, the lens member After positioning the lens member in focus while securing a gap that allows the lens member to move in the optical axis direction of the lens between the barrel and the barrel holder of the case member, the outer surface of the barrel and the inclination of the barrel holder are aligned by wedge ringing. Laser welding is performed while applying a uniform pressure to both the outer surface of the barrel and the inner peripheral surface of the wedge ring and between the inclined surface of the barrel holder and the outer peripheral inclined surface of the wedge ring. Therefore, stable laser welding can be performed in a focused state, and the barrel of the lens member can be attached to the barrel holder of the case member with sufficient strength. In addition, since laser welding is performed between the inner peripheral surface of the wedge ring and the outer peripheral surface of the barrel and between the outer peripheral inclined surface of the wedge ring and the inclined surface of the barrel holder, a sufficient welding area can be secured. It is possible to satisfactorily attach the barrel of the lens member to the barrel holder of the case member with sufficient strength.

さらに、本発明のカメラモジュールにおけるレンズ部材の取付方法によれば、第１〜第３の取付方法のいずれかにおいて、クサビリングとしてレーザを透過させる樹脂からなるものを用い、バレルホルダおよびバレルとしてレーザを吸収する樹脂からなるものを用いるときには、クサビリングの内周面とバレルの外側面との間およびクサビリングの外周傾斜面とバレルホルダの傾斜面との間に確実にレーザを照射して効率よく溶着を行なうことができ、十分な溶着面積にわたって所望通りにレーザを照射して溶着を行なうことができるので、十分な強度でレンズ部材のバレルをケース部材のバレルホルダに良好にかつ確実に取り付けることが可能となる。また、溶着後の溶着面の状態をクサビリングを通して目視あるいは画像認識によって確認することもできるので、溶着状態の検査を容易に行なうことも可能となる。   Furthermore, according to the method of attaching the lens member in the camera module of the present invention, any one of the first to third attachment methods uses a resin made of a resin that transmits laser as a wedge ring, and a laser as a barrel holder and a barrel. When using an absorbent resin, the laser beam is reliably irradiated between the inner peripheral surface of the wedge ring and the outer surface of the barrel and between the outer peripheral inclined surface of the wedge ring and the inclined surface of the barrel holder for efficient welding. Since it is possible to perform welding by irradiating the laser as desired over a sufficient welding area, it is possible to attach the lens member barrel to the barrel holder of the case member with sufficient strength. It becomes. In addition, since the state of the welded surface after welding can be confirmed visually or by image recognition through wedge ring, it is possible to easily inspect the welded state.

以下に、本発明のカメラモジュールにおけるレンズ部材の取付方法について添付図面を参照しつつ詳細に説明する。なお、以下の説明においては、カメラモジュールの前側にレンズが配置されるのに対してその反対側を後側という。   Hereinafter, a method for attaching a lens member in the camera module of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the lens is disposed on the front side of the camera module, while the opposite side is referred to as the rear side.

図１（ａ）は本発明のカメラモジュールにおけるレンズ部材の取付方法を適用するカメラモジュールの一例を示す分解斜視図であり、図１（ｂ）はその断面図であり、図１（ｃ）はケース部材にレンズ部材を取り付けた状態を示す正面図である。図１に示すように、この例のカメラモジュール10は、開口部に外側に向かって広がる傾斜面２ａを有するバレルホルダ２が設けられたケース部材１と、バレルホルダ２に取り付けられる円筒状のバレル４にレンズ５が装着されてなるレンズ部材３と、バレルホルダ２の傾斜面２ａに対応する外周傾斜面６ａおよびバレル４の外側面４ａに対応する内周面６ｂを有し、周方向の一部に切断部６ｃが形成されたクサビリング６とを具備している。   FIG. 1A is an exploded perspective view showing an example of a camera module to which the lens member mounting method in the camera module of the present invention is applied, FIG. 1B is a sectional view thereof, and FIG. It is a front view which shows the state which attached the lens member to the case member. As shown in FIG. 1, the camera module 10 of this example includes a case member 1 provided with a barrel holder 2 having an inclined surface 2 a that spreads outward at an opening, and a cylindrical barrel 4 attached to the barrel holder 2. The lens member 3 to which the lens 5 is attached, the outer peripheral inclined surface 6a corresponding to the inclined surface 2a of the barrel holder 2, and the inner peripheral surface 6b corresponding to the outer surface 4a of the barrel 4 are cut into a part in the circumferential direction. And a wedge ring 6 in which a portion 6c is formed.

このようなカメラモジュール10は、小型オンボードカメラをはじめとして、電子カメラや車載カメラとして用いられるものである。車載カメラとして用いられる場合であれば、車両の周囲の撮像，道路上の白線の撮像あるいは車両を運転する運転手の死角を撮像する機能を有し、例えば運転席の前方に設置されたディスプレイに画像を表示したり、画像信号が自動車の走行の制御を行なうＥＣＵ（エレクトロニック・コントロール・ユニット）に利用されたりする。   Such a camera module 10 is used as a small on-board camera, an electronic camera, and an in-vehicle camera. When used as an in-vehicle camera, it has a function of imaging the surroundings of a vehicle, imaging of white lines on a road, or the blind spot of a driver driving a vehicle, for example, on a display installed in front of a driver's seat An image is displayed, or an image signal is used in an ECU (Electronic Control Unit) that controls driving of an automobile.

ケース部材１は、前側にレンズ部材３が装着されるバレルホルダ２を有しており、内部の空間には撮像素子（図示せず）、例えばＣＣＤイメージセンサやＣＭＯＳイメージセンサ等の半導体イメージセンサ素子が撮像基板（図示せず）に搭載されて収納される。本例のケース部材１は、バレルホルダ２が設けられ、内部の空間に撮像素子が収納される前側の前部１ａと、前部１ａの内部の空間を封止する蓋状の後側の後部１ｂとが接合されて構成されている。バレルホルダ２は円筒状のバレル４が挿入される円筒状とされており、内径はバレル４の外径より若干大きい径となっている。バレルホルダ２の開口部には外側に向かって広がる傾斜面２ａを有している。この傾斜面２ａはクサビリング６の外周傾斜面６ａを当接させ密着させてレーザ溶着する面であり、この傾斜面２ａがあることによってバレル４を挿入しやすくもなっている。   The case member 1 has a barrel holder 2 to which a lens member 3 is attached on the front side, and an image sensor (not shown), for example, a semiconductor image sensor element such as a CCD image sensor or a CMOS image sensor, is provided in the internal space. It is mounted and stored on an imaging substrate (not shown). The case member 1 of this example is provided with a barrel holder 2, and a front part 1a on the front side in which an image sensor is accommodated in the internal space, and a lid-like rear part 1b on the back side that seals the space inside the front part 1a. Are joined together. The barrel holder 2 has a cylindrical shape into which the cylindrical barrel 4 is inserted, and the inner diameter is slightly larger than the outer diameter of the barrel 4. The opening of the barrel holder 2 has an inclined surface 2a that spreads outward. The inclined surface 2a is a surface on which the outer peripheral inclined surface 6a of the wedge ring 6 is brought into contact with and brought into close contact with the laser ring 6, and the presence of the inclined surface 2a makes it easy to insert the barrel 4.

レンズ部材３は、ケース部材１のバレルホルダ２に挿入されて取り付けられる円筒状のバレル４の内側にレンズ５が装着されてなるものである。レンズ５は、ケース部材１に収納された撮像素子に被写体光を集光するためのものであり、この例のレンズ部材３では、被写体光を広角度で集光するための前側の第１レンズと、第１レンズを通過した光を撮像素子に画像の歪みがない状態で焦点を合わせるための２枚のレンズとからなるレンズ群として構成されている。なお、本例のレンズ部材３においてはレンズ５の取付け構造は図示していないが、取付け構造に対する制約は特にない。   The lens member 3 is formed by mounting a lens 5 inside a cylindrical barrel 4 that is inserted into and attached to the barrel holder 2 of the case member 1. The lens 5 is for condensing subject light on the image sensor housed in the case member 1. In the lens member 3 of this example, the first lens on the front side for condensing subject light at a wide angle. And a lens group consisting of two lenses for focusing the light that has passed through the first lens in a state where there is no image distortion in the imaging device. In addition, in the lens member 3 of this example, although the attachment structure of the lens 5 is not illustrated, there is no restriction | limiting in particular with respect to an attachment structure.

このようなバレルホルダ２を有するケース部材１およびそのバレルホルダ２に取り付けられるバレル４は、例えば、射出成形によって樹脂材料を用いて成形することにより所定の形状に形成される。樹脂材料としては種々の材料を用いることができるが、例えばポリカーボネート（ＰＣ）やポリフタルアミド（ＰＰＡ），ポリオキシメチレン（ポリアセタール）（ＰＯＭ），ポリフェニレンサルファイド（ＰＰＳ），アクリロニトリルブタジエンスチレン（ＡＢＳ）等の樹脂を用いることにより、必要な耐久性を確保するとともに軽量化が図られている。通常は、ケース部材１の前部１ｂと後部１ｃとの間で、またケース部材１のバレルホルダ２とレンズ部材３のバレル４との間で熱膨張および熱収縮を合わせて熱応力の発生を抑えるために、これらに同一の樹脂材料を用いることが好ましく、また、クサビリング６とのレーザ溶着を容易に安定して行なうために融点の近い樹脂材料を用いることが好ましいが、カメラモジュール10に要求される仕様に応じて、異なる樹脂材料を用いたり、金属材料を用いたりして構成されていても構わない。   The case member 1 having such a barrel holder 2 and the barrel 4 attached to the barrel holder 2 are formed into a predetermined shape by molding using a resin material by, for example, injection molding. Various materials can be used as the resin material. For example, polycarbonate (PC), polyphthalamide (PPA), polyoxymethylene (polyacetal) (POM), polyphenylene sulfide (PPS), acrylonitrile butadiene styrene (ABS), etc. By using this resin, the required durability is ensured and the weight is reduced. Usually, thermal expansion and thermal contraction are combined between the front part 1b and the rear part 1c of the case member 1 and between the barrel holder 2 of the case member 1 and the barrel 4 of the lens member 3 to suppress the generation of thermal stress. Therefore, it is preferable to use the same resin material for these, and it is preferable to use a resin material having a close melting point in order to perform laser welding with the wedge ring 6 easily and stably. Depending on the specifications, different resin materials or metal materials may be used.

クサビリング６は、バレルホルダ２の傾斜面２ａに対応する外周傾斜面６ａおよびバレル４の外側面４ａに対応する内周面６ｂを有し、周方向の一部に切断部６ｃが形成されており、切断部６ｃが形成されていることによってバネ性を有している。クサビリング６の内径はバレル４の外径に対して若干小さい径となっており、バレル４の外側面４ａにはめ込んだ際に内周面６ｂがバレル４の外側面４ａにレーザ溶着を行なうのに十分な圧力で密着するようになっている。   The wedge ring 6 has an outer peripheral inclined surface 6a corresponding to the inclined surface 2a of the barrel holder 2 and an inner peripheral surface 6b corresponding to the outer surface 4a of the barrel 4, and a cutting portion 6c is formed in a part in the circumferential direction. Since the cut portion 6c is formed, it has a spring property. The inner diameter of the wedge ring 6 is slightly smaller than the outer diameter of the barrel 4, and the inner peripheral surface 6 b performs laser welding to the outer surface 4 a of the barrel 4 when fitted into the outer surface 4 a of the barrel 4. It comes in close contact with sufficient pressure.

このクサビリング６も、例えば、射出成形によって樹脂材料を用いて成形することにより形成される。クサビリング６の樹脂材料としても、例えばポリカーボネート（ＰＣ），ポリオキシメチレン（ＰＯＭ），ポリブチレンテレフタレト（ＰＢＴ），ポリフェニレンサルファイド（ＰＰＳ），環状オレフィンコポリマー（ＣＯＣ）等の樹脂を用いることにより、必要な耐久性を確保し、軽量化が図られる。通常は、バレルホルダ２およびバレル４との間で熱膨張および熱収縮を合わせて熱応力の発生を抑えるために、ならびにバレルホルダ２およびバレル４とのレーザ溶着を容易に安定して行なうために、バレルホルダ２およびバレル４と同一の樹脂材料または融点の近い樹脂材料を用いることが好ましいが、異なる樹脂材料を用いたり、金属材料を用いたりしても構わない。   The wedge ring 6 is also formed by molding using a resin material by, for example, injection molding. As a resin material for the wedge ring 6, for example, by using a resin such as polycarbonate (PC), polyoxymethylene (POM), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), cyclic olefin copolymer (COC), etc. The required durability is ensured and the weight is reduced. Usually, in order to suppress the occurrence of thermal stress by combining thermal expansion and contraction between the barrel holder 2 and the barrel 4, and in order to perform laser welding with the barrel holder 2 and the barrel 4 easily and stably, the barrel holder 2 and the same resin material as the barrel 4 or a resin material having a close melting point is preferably used, but a different resin material or a metal material may be used.

このような例のカメラモジュール10におけるケース部材１へのレンズ部材３の取付方法として、本発明の第１の取付方法の実施の形態の一例を図２に示す。図２（ａ）〜（ｃ）は、それぞれ本発明の第１のカメラモジュールにおけるレンズ部材の取付方法の実施の形態の一例を示す工程毎の側面図であり、図２（ｄ）は同じく断面図である。なお、図２において図１と同様の部位には同じ符号を付している。   As an attachment method of the lens member 3 to the case member 1 in the camera module 10 of such an example, an example of an embodiment of the first attachment method of the present invention is shown in FIG. FIGS. 2A to 2C are side views for each process showing an example of an embodiment of a lens member mounting method in the first camera module of the present invention, and FIG. FIG. In FIG. 2, the same parts as those in FIG.

図２に示す例においては、まず図２（ａ）に示すように、開口部に外側に向かって広がる傾斜面２ａを有するバレルホルダ２が設けられたカメラモジュールのケース部材１と、バレルホルダ２に取り付けられる円筒状のバレル４にレンズ５が装着されてなるレンズ部材３と、バレルホルダ２の傾斜面２ａに対応する外周傾斜面６ａおよびバレル４の外側面４ａに対応する内周面６ｂを有し、周方向の一部に切断部６ｃが形成されたクサビリング６とを準備する。   In the example shown in FIG. 2, first, as shown in FIG. 2A, the case member 1 of the camera module in which the barrel holder 2 having the inclined surface 2 a that spreads toward the outside is provided in the opening, and the barrel holder 2 is attached.

次いで、図２（ｂ）に示すように、レンズ部材３をバレルホルダ２に挿入する。   Next, the lens member 3 is inserted into the barrel holder 2 as shown in FIG.

次いで、図２（ｃ）に示すように、レンズ部材３をレンズ５の光軸方向に動かして、カメラモジュールの撮像面にレンズ５の焦点を合わせ、次に、バレル４の外側面４ａにクサビリング６をはめ込んで、焦点を合わせた位置にバレル４を保持したままでクサビリング６をバレルホルダ２の開口部まで移動させて、図２（ｄ）に示すように、クサビリング６の内周面６ｂをバレル４の外側面４ａに当接させるとともにクサビリング６の外周傾斜面６ａをバレルホルダ２の傾斜面２ａに当接させる。このとき、クサビリング６は、内径がバレル４の外径に対して若干小さい径となっており、図示されていないが切断部６ｃが形成されていることから、この切断部６ｃを若干広げるようにしてバレル４にはめ込むことによって、バレル４の外側面４ａ上をスムーズに移動させることができるとともに、内周面６ｂをバレル４の外側面４ａに対してレーザ溶着を行なうのに十分な圧力で密着させることができる。   Next, as shown in FIG. 2C, the lens member 3 is moved in the optical axis direction of the lens 5 so that the lens 5 is focused on the imaging surface of the camera module, and then the wedge 4 is formed on the outer surface 4 a of the barrel 4. The ring 6 is fitted and the wedge ring 6 is moved to the opening of the barrel holder 2 while holding the barrel 4 in the focused position, and the inner peripheral surface of the wedge ring 6 as shown in FIG. 6 b is brought into contact with the outer surface 4 a of the barrel 4, and the outer peripheral inclined surface 6 a of the wedge ring 6 is brought into contact with the inclined surface 2 a of the barrel holder 2. At this time, the wedge ring 6 has an inner diameter that is slightly smaller than the outer diameter of the barrel 4. Although not shown, a cutting portion 6 c is formed, so that the cutting portion 6 c is slightly widened. By fitting into the barrel 4, the outer surface 4 a of the barrel 4 can be smoothly moved, and the inner peripheral surface 6 b can be applied with a pressure sufficient to perform laser welding on the outer surface 4 a of the barrel 4. It can be adhered.

しかる後、図２（ｄ）に示すように、クサビリング６の外周傾斜面６ａに当接しているバレルホルダ２の傾斜面２ａおよびクサビリング６の内周面６ｂに当接しているバレル４の外側面４ａにレーザＬを照射して、クサビリング６をバレルホルダ２およびバレル４に溶着して、レンズ部材３をケース部材１に取り付ける。以上のようにして、図１に示す例のカメラモジュール10が作製される。   Thereafter, as shown in FIG. 2 (d), outside of the barrel 4 in contact with the inclined surface 2 a of the barrel holder 2 in contact with the outer peripheral inclined surface 6 a of the wedge ring 6 and the inner peripheral surface 6 b of the wedge ring 6. The side surface 4 a is irradiated with the laser L, the wedge ring 6 is welded to the barrel holder 2 and the barrel 4, and the lens member 3 is attached to the case member 1. As described above, the camera module 10 of the example shown in FIG. 1 is manufactured.

このような本発明の第１のカメラモジュールにおけるレンズ部材の取付方法によって、レンズ部材３のバレル４とケース部材１のバレルホルダ２との間にはレンズ部材３をレンズ５の光軸方向に動かせる隙間を確保しつつ、焦点を合わせてレンズ部材３を位置決めした後には、クサビリング６によってバレル４の外側面４ａとバレルホルダ２の傾斜面２ａとの間隔を埋めるとともに、バレル４の外側面４ａとクサビリング６の内周面６ｂとの間およびバレルホルダ２の傾斜面２ａとクサビリング６の外周傾斜面６ａとの間の両方に一様な圧力をかけながらレーザＬを照射してレーザ溶着を行なうことができるので、レンズ部材３を移動させてレンズ５の焦点合わせを行なった状態で安定して良好なレーザ溶着が可能となり、十分な強度でレンズ部材３のバレル４をケース部材１のバレルホルダ２に取り付けることが可能となる。また、クサビリング６の内周面６ｂとバレル４の外側面４ａとの間およびクサビリング６の外周傾斜面６ａとバレルホルダ２の傾斜面２ａとの間でレーザ溶着を行なうことから十分な溶着面積を確保することができるので、十分な強度でレンズ部材３のバレル４をケース部材１のバレルホルダ２に良好に取り付けることが可能となる。   By such a method of attaching the lens member in the first camera module of the present invention, a gap in which the lens member 3 can be moved in the optical axis direction of the lens 5 between the barrel 4 of the lens member 3 and the barrel holder 2 of the case member 1. After the lens member 3 is positioned while focusing, the space between the outer surface 4a of the barrel 4 and the inclined surface 2a of the barrel holder 2 is filled by the wedge ring 6, and the outer surface 4a of the barrel 4 and the wedge are filled. Laser welding is performed by irradiating laser L while applying uniform pressure to both the inner peripheral surface 6b of the ring 6 and between the inclined surface 2a of the barrel holder 2 and the outer peripheral inclined surface 6a of the wedge ring 6. Therefore, it is possible to stably and satisfactorily perform laser welding in a state where the lens member 3 is moved and the lens 5 is focused. It is possible to attach the barrel 4 of the member 3 to the barrel holder 2 of the case member 1. Further, a sufficient welding area is obtained because laser welding is performed between the inner peripheral surface 6b of the wedge ring 6 and the outer surface 4a of the barrel 4 and between the outer peripheral inclined surface 6a of the wedge ring 6 and the inclined surface 2a of the barrel holder 2. Therefore, it is possible to satisfactorily attach the barrel 4 of the lens member 3 to the barrel holder 2 of the case member 1 with sufficient strength.

しかる後、図４（ｄ）に示すように、クサビリング６の外周傾斜面６ａに当接しているバレルホルダ２の傾斜面２ａおよびクサビリング６の内周面６ｂに当接しているバレル４の外側面４ａにレーザＬを照射して、クサビリング６をバレルホルダ２およびバレル４に溶着して、レンズ部材３をケース部材１に取り付ける。以上のようにして、図１に示す例のカメラモジュール10が作製される。   Thereafter, as shown in FIG. 4 (d), the outside of the barrel 4 in contact with the inclined surface 2 a of the barrel holder 2 in contact with the outer peripheral inclined surface 6 a of the wedge ring 6 and the inner peripheral surface 6 b of the wedge ring 6. The side surface 4 a is irradiated with the laser L, the wedge ring 6 is welded to the barrel holder 2 and the barrel 4, and the lens member 3 is attached to the case member 1. As described above, the camera module 10 of the example shown in FIG. 1 is manufactured.

このような本発明の第３のカメラモジュールにおけるレンズ部材の取付方法によっても、レンズ部材３のバレル４とケース部材１のバレルホルダ２との間にはレンズ部材３をレンズ５の光軸方向に動かせる隙間を確保しつつ、焦点を合わせてレンズ部材３を位置決めした後には、クサビリング６によってバレル４の外側面４ａとバレルホルダ２の傾斜面２ａとの間隔を埋めるとともに、バレル４の外側面４ａとクサビリング６の内周面６ｂとの間およびバレルホルダ２の傾斜面２ａとクサビリング６の外周傾斜面６ａとの間の両方に一様な圧力をかけながらレーザＬを照射してレーザ溶着を行なうことができるので、レンズ部材３を移動させてレンズ５の焦点合わせを行なった状態で安定して良好なレーザ溶着が可能となり、十分な強度でレンズ部材３のバレル４をケース部材１のバレルホルダ２に取り付けることが可能となる。また、クサビリング６の内周面６ｂとバレル４の外側面４ａとの間およびクサビリング６の外周傾斜面６ａとバレルホルダ２の傾斜面２ａとの間でレーザ溶着を行なうことから十分な溶着面積を確保することができるので、十分な強度でレンズ部材３のバレル４をケース部材１のバレルホルダ２に良好に取り付けることが可能となる。   The lens member 3 can be moved in the optical axis direction of the lens 5 between the barrel 4 of the lens member 3 and the barrel holder 2 of the case member 1 also by the lens member mounting method in the third camera module of the present invention. After positioning the lens member 3 in focus while securing a gap, the wedge ring 6 fills the gap between the outer surface 4a of the barrel 4 and the inclined surface 2a of the barrel holder 2, and the outer surface 4a of the barrel 4 Laser welding is performed by irradiating the laser L while applying uniform pressure to both the inner peripheral surface 6b of the wedge ring 6 and between the inclined surface 2a of the barrel holder 2 and the outer peripheral inclined surface 6a of the wedge ring 6. As a result, it is possible to stably and satisfactorily perform laser welding in a state where the lens member 3 is moved and the lens 5 is focused. It is possible to attach the barrel 4's member 3 to barrel holder 2 of the case member 1. Further, a sufficient welding area is obtained because laser welding is performed between the inner peripheral surface 6b of the wedge ring 6 and the outer surface 4a of the barrel 4 and between the outer peripheral inclined surface 6a of the wedge ring 6 and the inclined surface 2a of the barrel holder 2. Therefore, it is possible to satisfactorily attach the barrel 4 of the lens member 3 to the barrel holder 2 of the case member 1 with sufficient strength.

そして、以上の本発明の第１〜第３の取付方法においては、クサビリング６としてレーザＬを透過させる樹脂からなるものを用い、バレルホルダ２およびバレル４としてレーザＬを吸収する樹脂からなるものを用いることが好ましい。このときには、クサビリング６の内周面６ｂとバレル４の外側面４ａとの間およびクサビリング６の外周傾斜面６ａとバレルホルダ２の傾斜面２ａとの間に確実にレーザＬを照射して効率よく溶着を行なうことができ、十分な溶着面積にわたって所望通りにレーザＬを照射して溶着を行なうことができるので、十分な強度でレンズ部材３のバレル４をケース部材１のバレルホルダ２に良好にかつ確実に取り付けることが可能となる。また、溶着後の溶着面の状態をクサビリング６を通して目視あるいは画像認識によって確認することもできるので、溶着状態の検査を容易に行なうことも可能となる。   In the first to third mounting methods of the present invention described above, the wedge ring 6 is made of a resin that transmits the laser L, and the barrel holder 2 and the barrel 4 are made of a resin that absorbs the laser L. It is preferable to use it. At this time, the laser L is reliably irradiated between the inner peripheral surface 6b of the wedge ring 6 and the outer surface 4a of the barrel 4 and between the outer peripheral inclined surface 6a of the wedge ring 6 and the inclined surface 2a of the barrel holder 2 for efficiency. Since welding can be performed well and laser L can be irradiated as desired over a sufficient welding area, the barrel 4 of the lens member 3 can be satisfactorily attached to the barrel holder 2 of the case member 1 with sufficient strength. And it becomes possible to attach reliably. Further, since the state of the welded surface after welding can be confirmed through visual inspection or image recognition through the wedge ring 6, it is possible to easily inspect the welded state.

また、このようなクサビリング６に好適なレーザＬとしては、半導体レーザやファイバレーザ（波長：800ｎｍ〜、出力：必要な条件によって異なるが、数Ｗ〜数千Ｗ）を用いるとよい。   Further, as the laser L suitable for the wedge ring 6, a semiconductor laser or a fiber laser (wavelength: 800 nm˜, output: depending on necessary conditions, several W to several thousand W) may be used.

また、クサビリング６に好適なレーザＬを透過させる樹脂としては、例えばポリオキシメチレン（ＰＯＭ），ポリブチレンテレフタレト（ＰＢＴ），ポリフェニレンサルファイド（ＰＰＳ），環状オレフィンコポリマー（ＣＯＣ）がある。   Examples of the resin that transmits the laser L suitable for the wedge ring 6 include polyoxymethylene (POM), polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), and cyclic olefin copolymer (COC).

また、バレルホルダ２およびバレル４に好適なレーザＬを吸収する樹脂としては、例えば上記のクサビリング６に好適な樹脂材料にカーボンブラック等のレーザＬの吸収を補助する添加剤を添加したものがある。   Examples of the resin that absorbs the laser L suitable for the barrel holder 2 and the barrel 4 include, for example, a resin material suitable for the wedge ring 6 to which an additive for assisting the absorption of the laser L such as carbon black is added. .

本発明は、上述した実施の形態の例に限定されるものではなく、本発明の要旨を逸脱しない範囲において種々の変更，改良等が可能である。   The present invention is not limited to the above-described embodiments, and various changes and improvements can be made without departing from the scope of the present invention.

例えば、図５にクサビリング６の他の例の側面図で示すように、切断部６ｃの側面から見た形状を凹凸状（クランク状）とすることにより、クサビリング６の内周面６ｂをバレル４の外側面４ａに当接させるとともにクサビリング６の外周傾斜面６ａをバレルホルダ２の傾斜面２ａに当接させるようにクサビリング６に圧力をかけた際に、切断部６ｃを閉じてクサビリング６の外周傾斜面６ａおよび両端面を滑らかにすることが容易になる。   For example, as shown in a side view of another example of the wedge ring 6 in FIG. 5, the inner peripheral surface 6 b of the wedge ring 6 is formed by making the shape viewed from the side surface of the cutting portion 6 c uneven (crank shape). When pressure is applied to the wedge ring 6 so that the outer peripheral inclined surface 6a of the barrel ring 6 is brought into contact with the outer surface 4a of the barrel 4 and the inclined surface 2a of the barrel holder 2, the cutting portion 6c is closed and the wedge is closed. It becomes easy to smooth the outer peripheral inclined surface 6a and both end surfaces of the ring 6.
