Description

本発明は、レンズを保持したホルダの下部に撮像素子を有した基板を固着してなるカメラモジュールに関し、特にホルダと基板の平行度を確実に保って固着することのできるカメラモジュールに関する。   The present invention relates to a camera module in which a substrate having an image sensor is fixed to a lower part of a holder holding a lens, and more particularly to a camera module that can be fixed while maintaining the parallelism between the holder and the substrate.

従来、レンズを保持したホルダの下部に撮像素子を有した基板を固着してなるカメラモジュールが知られている。このようなカメラモジュールにおいては、ホルダのうち撮像素子と対向する領域に突起を設けて、この突起の下面を撮像素子に対して当接させることで位置出しを行い、また突起よりも外周側に筒状の突出部を設け、この突出部を基板に対し接着剤を介して固着することで、ホルダと基板を固定するようにしていた。このようなカメラモジュールとしては、例えば特許文献１に挙げるようなものがある。
特開２００４−１７３０３１号公報 2. Description of the Related Art Conventionally, a camera module is known in which a substrate having an image sensor is fixed to a lower part of a holder that holds a lens. In such a camera module, a protrusion is provided in a region of the holder that faces the image sensor, and positioning is performed by bringing the lower surface of the protrusion into contact with the image sensor. A cylindrical protrusion is provided, and the holder and the substrate are fixed by fixing the protrusion to the substrate with an adhesive. As such a camera module, there is one as disclosed in Patent Document 1, for example.
JP 2004-173031 A

しかし、従来のカメラモジュールにおいては、ホルダの撮像素子に対する位置決めを行う突起が四箇所設けられていた。一方で、ホルダの撮像素子に対する位置決めの基準面は、三点で決定されるため、四箇所の突起のうち一つは撮像素子の上面から浮いた状態となる。いずれの突起が撮像素子の上面から浮いた状態となるかは、加工精度の問題により必ずしも一定しない。このため、ホルダを撮像素子上に載置した際にがたつきが生じると共に、ホルダの撮像素子に対する平行度を一定に保つことが困難であった。またこれによって光学的な性能を充分に確保できないことがあった。   However, in the conventional camera module, four protrusions for positioning the holder with respect to the image sensor are provided. On the other hand, since the reference plane for positioning the holder with respect to the image sensor is determined at three points, one of the four protrusions is in a state of floating from the upper surface of the image sensor. Which projection is lifted from the upper surface of the image sensor is not necessarily constant due to processing accuracy. For this reason, rattling occurs when the holder is placed on the image sensor, and it is difficult to keep the parallelism of the holder with respect to the image sensor constant. In addition, this may not ensure sufficient optical performance.

本発明は上記課題を鑑みてなされたものであり、ホルダの撮像素子に対する平行度を一定に保って確実に位置決めできるカメラモジュールを提供することを目的とする。   The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a camera module that can be reliably positioned while maintaining the parallelism of the holder with respect to the imaging device constant.

上記課題を解決するため、本発明に係るカメラモジュールは、筒状に形成され内部にレンズを保持したホルダと、該ホルダの下部に固着される平板状の基板と、該基板上に配置される撮像素子とを備えたカメラモジュールにおいて、
前記ホルダは前記撮像素子と対向する天面部を備え、該天面部には前記撮像素子に向かって突出し下面が当接する突部が形成され、該突部は前記天面部に三箇所形成されると共に、前記ホルダの重心の前記基板の平面方向位置が前記突部を結んだ三角形内となるように前記突部が配置されることを特徴として構成されている。 In order to solve the above-described problems, a camera module according to the present invention includes a holder formed in a cylindrical shape and holding a lens therein, a flat substrate fixed to a lower portion of the holder, and disposed on the substrate. In a camera module equipped with an image sensor,
The holder includes a top surface portion that faces the image sensor, and the top surface portion is formed with protrusions that project toward the image sensor and contact the lower surface, and the protrusions are formed at three locations on the top surface portion. The protrusions are arranged such that the position of the center of gravity of the holder in the plane direction of the substrate is within the triangle connecting the protrusions.

また、本発明に係るカメラモジュールは、前記ホルダは前記天面部より外周側に前記基板に向かって延びる筒状外周部を備え、前記突部の下面が前記撮像素子に当接した状態で、前記筒状外周部の下面は前記基板と接着剤を介して固着されることを特徴として構成されている。   Further, in the camera module according to the present invention, the holder includes a cylindrical outer peripheral portion extending toward the substrate on the outer peripheral side from the top surface portion, and the lower surface of the protrusion is in contact with the imaging element, The bottom surface of the cylindrical outer peripheral portion is configured to be fixed to the substrate via an adhesive.

さらに、本発明に係るカメラモジュールは、前記ホルダの天面部には前記撮像素子に向かって突出する第２の突部が形成され、該第２の突部は前記突部よりも短く形成され、前記突部が前記撮像素子に当接した状態で、下面が前記撮像素子と隙間を有して対向し、かつ前記第２の突部は前記天面部における平面方向位置が前記突部を結んだ三角形の外側に配置されることを特徴として構成されている。   Furthermore, in the camera module according to the present invention, a second protrusion that protrudes toward the image sensor is formed on the top surface of the holder, and the second protrusion is formed shorter than the protrusion. In a state where the protrusion is in contact with the image sensor, the lower surface faces the image sensor with a gap, and the second protrusion has a planar position on the top surface that connects the protrusion. It is configured to be arranged outside the triangle.

さらにまた、本発明に係るカメラモジュールは、前記第２の突部は前記天面部に少なくとも二つ形成され、前記第２の突部のうち一つは所定の二つの突部間の領域に配置され、前記第２の突部のうち他の一つは前記所定の二つの突部間と異なる二つの突部間の領域に配置されることを特徴として構成されている。   Furthermore, in the camera module according to the present invention, at least two of the second protrusions are formed on the top surface part, and one of the second protrusions is disposed in a region between the two predetermined protrusions. The other one of the second protrusions is arranged in a region between the two protrusions different from the predetermined two protrusions.

本発明に係るカメラモジュールによれば、ホルダの天面部には撮像素子に向かって突出し下面が当接する突部が形成され、突部は天面部に三箇所形成され、ホルダの重心の基板の平面方向位置が突部を結んだ三角形内となるように突部が配置されることにより、三つの突部により特定される平面が常にホルダの撮像素子に対する位置決めの基準面となるので、ホルダの撮像素子に対する平行度を保って確実に位置決めすることができる。   According to the camera module of the present invention, the top surface portion of the holder is formed with protrusions that protrude toward the image sensor and the lower surface contacts, the protrusions are formed at three positions on the top surface portion, and the plane of the substrate at the center of gravity of the holder By arranging the protrusions so that the directional position is within the triangle connecting the protrusions, the plane specified by the three protrusions is always the reference plane for positioning the holder with respect to the image sensor, so that the image of the holder is imaged. Positioning can be performed reliably while maintaining parallelism with respect to the element.

また、本発明に係るカメラモジュールによれば、突部の下面が撮像素子に当接した状態で、筒状外周部の下面は基板と接着剤を介して固着されることにより、必ず突部によってホルダの撮像素子に対する位置決めがなされるので、この位置決めをより確実にすることができる。   Further, according to the camera module of the present invention, the bottom surface of the cylindrical outer peripheral portion is fixed to the substrate via the adhesive while the bottom surface of the projection is in contact with the image sensor, so Since the holder is positioned with respect to the image sensor, this positioning can be made more reliable.

さらに、本発明に係るカメラモジュールによれば、ホルダの天面部には撮像素子に向かって突出する第２の突部が形成され、第２の突部は突部よりも短く形成され、突部が撮像素子に当接した状態で、下面が撮像素子と隙間を有して対向し、かつ第２の突部は天面部における平面方向位置が突部を結んだ三角形の外側に配置されることにより、ホルダが基板に接着固定される前に傾斜しても、第２の突部が撮像素子に当接することでホルダが大きく傾斜しないので、自重により確実にホルダを元の位置に復帰させることができて、ホルダの傾倒による位置ずれを防止することができる。   Further, according to the camera module of the present invention, the top surface portion of the holder is formed with the second protrusion that protrudes toward the image sensor, and the second protrusion is formed shorter than the protrusion. Is in contact with the image sensor, the lower surface faces the image sensor with a gap, and the second protrusion is disposed outside the triangle whose plane direction position on the top surface portion connects the protrusions. Thus, even if the holder is tilted before being bonded and fixed to the substrate, the holder does not largely tilt because the second protrusion comes into contact with the imaging device, so that the holder can be reliably returned to its original position by its own weight. It is possible to prevent misalignment due to tilting of the holder.

さらにまた、本発明に係るカメラモジュールによれば、第２の突部は天面部に少なくとも二つ形成され、第２の突部のうち一つは所定の二つの突部間の領域に配置され、第２の突部のうち他の一つは所定の二つの突部間と異なる二つの突部間の領域に配置されることにより、ホルダの傾倒を左右両側について防止することができ、ホルダの位置ずれをより確実に防止することができる。   Furthermore, according to the camera module of the present invention, at least two second protrusions are formed on the top surface, and one of the second protrusions is disposed in a region between the two predetermined protrusions. The other one of the second protrusions is disposed in a region between the two protrusions different from the predetermined two protrusions, so that the holder can be prevented from tilting on both the left and right sides. Can be reliably prevented.

本発明の実施形態について図面に沿って詳細に説明する。図１には本実施形態におけるカメラモジュールの断面図を示している。この図に示すように、本実施形態のカメラモジュールは、筒状に形成されるホルダ１と、ホルダ１の内部に保持されるレンズ２と、ホルダ１の下部に固着される基板３と、基板３上に配置される撮像素子４とから構成されており、レンズ２により集光された光が撮像素子４によって光電変換され、画像データを取り出すことができるものである。   Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional view of the camera module in the present embodiment. As shown in this figure, the camera module of this embodiment includes a holder 1 formed in a cylindrical shape, a lens 2 held inside the holder 1, a substrate 3 fixed to the lower portion of the holder 1, and a substrate. 3 is configured such that light collected by the lens 2 is photoelectrically converted by the image sensor 4 and image data can be extracted.

ホルダ１は、レンズ２を保持するレンズ保持部１１を内部に有した鏡筒部１０と、基板３と固着される基部１２とが一体的に形成されている。また、鏡筒部１０は略円柱状に形成され、基部１２は略四角柱状に形成される。鏡筒部１０内部のレンズ保持部１１には、レンズ２が保持されていると共に、レンズ保持部１１の底面部分には、赤外線を除去するためのフィルタ５が設けられる。基部１２の下部の中央側は、撮像素子４と対向する天面部１３を構成し、基部１２の下部の外周側には、基板３に対し接着剤１５を介して固着される筒状外周部１４が全周に渡って形成されている。   In the holder 1, a lens barrel portion 10 having a lens holding portion 11 for holding the lens 2 therein and a base portion 12 fixed to the substrate 3 are integrally formed. Further, the lens barrel portion 10 is formed in a substantially cylindrical shape, and the base portion 12 is formed in a substantially rectangular column shape. The lens 2 is held in the lens holding part 11 inside the lens barrel part 10, and a filter 5 for removing infrared rays is provided on the bottom part of the lens holding part 11. The center side of the lower portion of the base portion 12 constitutes a top surface portion 13 that faces the imaging device 4, and the cylindrical outer peripheral portion 14 that is fixed to the substrate 3 via the adhesive 15 on the outer peripheral side of the lower portion of the base portion 12. Is formed over the entire circumference.

次に、ホルダ１の構成についてより詳細に説明する。図２には、ホルダ１の底面図を示している。なお、図１は、この図のＡ−Ａ断面を含むカメラモジュールの断面図として表されている。図２に示すように、ホルダ１の底面はレンズ保持部１１と連通する開口部１２ａを有すると共に、それを取り囲むように前述の天面部１３を有し、この天面部１３には撮像素子４側に向かって突出する突部１６が形成されている。   Next, the configuration of the holder 1 will be described in more detail. FIG. 2 shows a bottom view of the holder 1. FIG. 1 is represented as a cross-sectional view of the camera module including the AA cross section of this figure. As shown in FIG. 2, the bottom surface of the holder 1 has an opening 12 a that communicates with the lens holding portion 11, and the above-described top surface portion 13 so as to surround the opening 12 a, and the top surface portion 13 includes the image sensor 4 side. A protrusion 16 that protrudes toward the surface is formed.

突部１６は、天面部１３に三箇所形成されている。天面部１３の外周は、基部１２の外周形状に合わせて略正方形状とされており、突部１６のうち一つは、天面部１３の外周を構成する一辺の中央部に配置される。また、突部１６の残りの二つは、前記の一辺とは対向する天面部１３の外周を構成する一辺の両端近傍にそれぞれ配置される。これら三つの突部１６を結ぶと、図中破線で示すように二等辺三角形となる。   The protrusions 16 are formed in three places on the top surface portion 13. The outer periphery of the top surface portion 13 has a substantially square shape in accordance with the outer periphery shape of the base portion 12, and one of the protrusions 16 is disposed at the center of one side that forms the outer periphery of the top surface portion 13. Further, the remaining two of the protrusions 16 are respectively arranged in the vicinity of both ends of one side that constitutes the outer periphery of the top surface portion 13 that faces the one side. When these three protrusions 16 are connected, an isosceles triangle is formed as indicated by a broken line in the figure.

図３には、図１のうちＢ領域の拡大図を示している。この図に示すように、ホルダ１の突部１６は、その下面が撮像素子４の上面に当接している。そして、図２に示すようにこの突部１６は三箇所形成されている。一つの平面は三点で特定することができ、したがってこの三箇所の突部１６によってこれらを結ぶ二等辺三角形を含む平面が特定される。この平面が、ホルダ１の撮像素子４に対する位置決めの基準面となる。突部１６が三箇所設けられていることにより、各突部１６が撮像素子４の上面に当接するようホルダ１を載置することで、必ず同じ突部１６によって位置決めの基準面が形成されるので、ホルダ１の撮像素子４に対する平行度を常に一定に保つことができ、正確な位置決めをすることができる。   FIG. 3 shows an enlarged view of region B in FIG. As shown in this figure, the lower surface of the protrusion 16 of the holder 1 is in contact with the upper surface of the image sensor 4. And as shown in FIG. 2, this protrusion 16 is formed in three places. One plane can be specified by three points. Therefore, a plane including an isosceles triangle connecting these three protrusions 16 is specified. This plane is a reference plane for positioning the holder 1 with respect to the image sensor 4. Since the protrusions 16 are provided at three places, the positioning reference surface is always formed by the same protrusion 16 by placing the holder 1 so that each protrusion 16 abuts the upper surface of the image sensor 4. Therefore, the parallelism of the holder 1 with respect to the image sensor 4 can always be kept constant, and accurate positioning can be performed.

そして、このように突部１６が撮像素子４の上面に当接して位置決めがなされた上で、図１に示すようにホルダ１の筒状外周部１４が接着剤１５を介して基板３に対して固定される。これによってホルダ１と基板３及び撮像素子４が一体化される。   Then, after the protrusion 16 is in contact with the upper surface of the image sensor 4 and positioned as described above, the cylindrical outer peripheral portion 14 of the holder 1 is attached to the substrate 3 through the adhesive 15 as shown in FIG. Fixed. As a result, the holder 1, the substrate 3 and the image sensor 4 are integrated.

また、ホルダ１は、基部１２が略四角柱状であると共に、鏡筒部１０が略円柱状に形成されていることにより、その重心は開口部１２ａの略中心線上にあり、その重心の基板平面方向位置が、三つの突部１６を結んだ二等辺三角形内となるように、突部１６の配置が定められている。突部１６がこのように天面部１３に配置されていることにより、安定的にホルダ１を撮像素子４に対して載置することができる。   In addition, the holder 1 has a base 12 having a substantially quadrangular prism shape, and the lens barrel portion 10 is formed in a substantially columnar shape, so that the center of gravity is substantially on the center line of the opening 12a. The arrangement of the protrusions 16 is determined so that the directional position is within an isosceles triangle connecting the three protrusions 16. Since the protrusion 16 is arranged on the top surface portion 13 in this way, the holder 1 can be stably placed on the image sensor 4.

さらに、天面部１３には突部１６の他に撮像素子４に向かって突出する第２の突部１７が形成されている。第２の突部１７は、中央部に突部１６が配置された天面部１３の外周を構成する一辺の両端部近傍にそれぞれ配置される。これら第２の突部１７のうち、図２中で右側に配置された一つは、天面部１３の外周部において、図２中で上側に配置された突部１６と、図２中で右下側に配置された突部１６との間の領域に配置され、また図２中で左側に配置された一つは、天面部１３の外周部において、図２中で上側に配置された突部１６と、図２中で左下側に配置された突部１６との間の領域に配置される。これによって第２の突部１７は、いずれも天面部１３における平面方向位置が、三つの突部１６を結んだ二等辺三角形の外側に配置されている。   Furthermore, in addition to the protrusion 16, a second protrusion 17 that protrudes toward the image sensor 4 is formed on the top surface portion 13. The 2nd protrusion 17 is each arrange | positioned in the vicinity of the both ends of one side which comprises the outer periphery of the top | upper surface part 13 by which the protrusion 16 is arrange | positioned in the center part. Among these second protrusions 17, one arranged on the right side in FIG. 2 is a protrusion 16 arranged on the upper side in FIG. The one arranged on the left side in FIG. 2 and the one arranged on the left side in FIG. 2 is the protrusion arranged on the upper side in FIG. It arrange | positions in the area | region between the part 16 and the protrusion 16 arrange | positioned in the lower left side in FIG. As a result, the second protrusions 17 are all arranged on the outside of the isosceles triangle connecting the three protrusions 16 in the plane direction position on the top surface part 13.

図４には、図１のうちＣ領域の拡大図を示している。この図に示すように、ホルダ１の第２の突部１７は、撮像素子４の上面に当接する突部１６よりも短く形成されており、このため第２の突部１７の下面は、撮像素子４と隙間を有して対向している。なお、図４において第２の突部１７の下面と撮像素子４との間の隙間は誇張して表しており、実際にはこれらはさらに近接するように第２の突部１７が形成される。   FIG. 4 shows an enlarged view of region C in FIG. As shown in this figure, the second protrusion 17 of the holder 1 is formed shorter than the protrusion 16 that comes into contact with the upper surface of the imaging element 4, so that the lower surface of the second protrusion 17 is It faces the element 4 with a gap. In FIG. 4, the gap between the lower surface of the second protrusion 17 and the image sensor 4 is exaggerated, and the second protrusion 17 is actually formed so as to be closer to each other. .

突部１６は、前述のように天面部１３に三箇所設けられているため、ホルダ１が、基板３に対して接着固定される前に、突部１６が形成されていない領域に向かって大きく下方傾斜し傾倒した場合、その状態から復帰できないことがある。これに対し、平面方向位置が突部１６を結んだ三角形の外側であって、互いに異なる二つの突部１６間に配置され、突部１６よりも短く形成された第２の突部１７を設けたことにより、ホルダ１が接着固定前に傾斜しても、第２の突部１７が撮像素子４に当接するためにホルダ１が大きく傾斜することがなく、したがってホルダ１は自重により元の状態に復帰することができる。   Since the protrusions 16 are provided at three places on the top surface part 13 as described above, the protrusions 16 are greatly increased toward the region where the protrusions 16 are not formed before the holder 1 is bonded and fixed to the substrate 3. When tilted downward and tilted, it may not be possible to recover from that state. On the other hand, a second projecting portion 17 is provided which is disposed between two projecting portions 16 whose planar positions are outside the triangle connecting the projecting portions 16 and which are different from each other. As a result, even if the holder 1 is tilted before being fixed to the adhesive, the holder 1 is not largely tilted because the second protrusion 17 is in contact with the image sensor 4. Can return to.

これまで説明したように、ホルダ１の天面部１３に三箇所の突部１６を設けたことで、ホルダ１の撮像素子４に対する平行度を常に一定に保つことができ、また天面部１３に第２の突部１７を設けたことで、突部１６が三箇所しか設けられていないことに伴い、ホルダ１が大きく傾倒し元の位置に復帰できなくなることを防止することができる。したがって、ホルダ１を撮像素子４に対して確実に一定の平行度を保って位置決め固定することができるので、カメラモジュールの光学性能を確実に一定以上に確保することができる。   As described above, by providing the three protrusions 16 on the top surface portion 13 of the holder 1, the parallelism of the holder 1 with respect to the image sensor 4 can be kept constant, and the top surface portion 13 By providing the two protrusions 17, it is possible to prevent the holder 1 from being greatly tilted and unable to return to the original position due to the fact that the protrusions 16 are provided only in three places. Therefore, the holder 1 can be reliably positioned and fixed with respect to the image sensor 4 while maintaining a certain degree of parallelism, so that the optical performance of the camera module can be ensured to a certain level or more.

以上、本発明の実施形態について説明したが、本発明の適用は本実施形態には限られず、その技術的思想の範囲内において様々に適用されうるものである。例えば、ホルダ１の天面部１３に形成される突部１６及び第２の突部１７の配置については、本実施形態のものには限られない。突部１６については、ホルダ１の重心の基板３の平面方向位置が突部１６を結んだ三角形内となるように配置するものであれば、本実施形態の配置には限られないし、第２の突部１７については、天面部１３における平面方向位置が突部１６を結んだ三角形の外側に配置されていればよい。   Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea. For example, the arrangement of the protrusions 16 and the second protrusions 17 formed on the top surface part 13 of the holder 1 is not limited to that of this embodiment. The protrusion 16 is not limited to the arrangement of the present embodiment as long as it is arranged so that the planar position of the substrate 3 at the center of gravity of the holder 1 is within the triangle connecting the protrusions 16. As for the protrusion 17, it is only necessary that the position in the plane direction of the top surface portion 13 is disposed outside the triangle connecting the protrusions 16.
