Description

本発明は、例えばマシンビジョンシステムに適用して好適な電子撮像カメラのマウント構造に関する。   The present invention relates to a mount structure for an electronic imaging camera suitable for application to, for example, a machine vision system.

マシンビジョンシステムにおいては、工業用の電子撮像カメラとして、撮像素子となるエリアイメージセンサにＣＣＤ（Charge Coupled Device）を用いた工業用ＣＣＤカメラが広く用いられている。この種、工業用ＣＣＤカメラは、高精度の撮像出力が要求されるとともに、使用形態も多岐に亘ることから塵埃が多く飛散する設置環境を考慮した気密性の高い防塵構造が要求される。   In the machine vision system, an industrial CCD camera using a CCD (Charge Coupled Device) as an area image sensor serving as an image sensor is widely used as an industrial electronic imaging camera. This type of industrial CCD camera is required to have a high-accuracy imaging output, and also has a wide variety of usage forms. Therefore, a highly airtight dustproof structure is required in consideration of an installation environment in which much dust is scattered.

従来、この種、ＣＣＤ撮像面の防塵構造は、レンズマウントと、エリアイメージセンサ（例えばＣＣＤ）を備えたセンサマウント（デバイスホルダ）との間に、Ｏリング、防塵用のホルダ、遮光板、カバーガラス、防塵ゴム等がそれぞれ個別に重ねて設けられる構造であり、これらの各部品がそれぞれ別体構成であることから、部品点数が多く、作業性並びに経済性に問題があった。ＣＣＤ撮像面の防塵構造に特徴をもつ従来技術として、防塵部材を、バネ定数が小さく、かつ内部の反射光が撮像面に入射しない構造にした防塵構造（特許文献１）や、防塵ゴムの反発力によって生ずる撮像素子の受光面の傾きの問題を防塵ゴムの形状により解消した取り付け構造（特許文献２）などが存在した。
特開２００１−２７５０２３ 特開２００６−１００８７８ Conventionally, this type of dust-proof structure on the CCD imaging surface has an O-ring, a dust-proof holder, a light-shielding plate, and a cover between a lens mount and a sensor mount (device holder) having an area image sensor (for example, CCD). Glass, dust-proof rubber, and the like are provided separately on each other, and since each of these parts has a separate structure, the number of parts is large and there are problems in workability and economy. As a conventional technique characterized by a dust-proof structure on the CCD imaging surface, a dust-proof member (Patent Document 1) in which the dust-proof member has a small spring constant and internal reflected light is not incident on the imaging surface, or repulsion of dust-proof rubber There has been an attachment structure (Patent Document 2) in which the problem of the inclination of the light receiving surface of the image sensor caused by force is solved by the shape of the dust-proof rubber.

しかしながら、これらの従来技術に於いても製品化する実際の組立構造においては、上述したような、Ｏリング、ホルダ、遮光板、カバーガラス、防塵ゴム等の各部品をそれぞれ個別に重ねる構造であり、これらの各部品がそれぞれ別体構成であることから、部品点数が多く、作業性並びに経済性に問題があった。   However, in the actual assembly structure that is commercialized even in these conventional technologies, the components such as the O-ring, the holder, the light shielding plate, the cover glass, and the dust-proof rubber are individually stacked as described above. Since each of these parts has a separate configuration, the number of parts is large and there are problems in workability and economy.

本発明は上記問題を解消して、部品点数を削減して、生産性の向上、並びに製造コストの低減化を図った電子撮像カメラのマウント構造を提供することを目的とする。   SUMMARY OF THE INVENTION An object of the present invention is to provide a mount structure for an electronic imaging camera that solves the above problems, reduces the number of parts, improves productivity, and reduces manufacturing costs.

The dust-proof structure includes a holder attached to the sensor mount, a light-shielding plate and a cover glass, and a dust-proof rubber body having a support frame portion that supports the holder, the light-shielding plate and the cover glass in a stacked state; And an O-ring that is integrally provided on the dust-proof rubber main body via a bent portion, and that is folded from the bent portion and clamps and fixes the holder, the light shielding plate, and the cover glass to the support frame portion of the dust-proof rubber main body. It is characterized by the mounting structure of the electronic imaging camera configured as described above.

本発明によれば、部品点数を削減でき、生産性を向上できるとともに製造コストを低減できる。   According to the present invention, the number of parts can be reduced, productivity can be improved, and manufacturing cost can be reduced.

上記したマウント構造の組立手順は、まず防塵ゴム本体１２ａに一体に設けられたＯリング１２ｃを折曲部１２ｂ，１２ｂから折り畳んで、ホルダ１３、遮光板１４およびカバーガラス１５を内包し、上記嵌め込み構造をホルダ１３に嵌合して、ホルダ１３、遮光板１４およびカバーガラス１５と、防塵ゴム本体１２ａおよびＯリング１２ｃとを一組にした組立構造体を構成する。または、上記組立構造体に加え、防塵ゴム本体１２ａの他方の開口面部にＣＣＤ１６の撮像面１７の周部を嵌め込むことで、ホルダ１３、遮光板１４およびカバーガラス１５と、防塵ゴム本体１２ａおよびＯリング１２ｃとに加えて、ＣＣＤ１６を密着状態で一体化した一組の組立構造体を構成する。この一組の組立構造体の一例を図２に示している。ここではＣＣＤ１６を含んだ一組の組立構造体を例示している。   The assembly procedure of the mounting structure described above is as follows. First, the O-ring 12c provided integrally with the dust-proof rubber main body 12a is folded from the bent portions 12b and 12b, and the holder 13, the light shielding plate 14 and the cover glass 15 are enclosed, and the fitting is performed. The structure is fitted to the holder 13 to constitute an assembly structure in which the holder 13, the light shielding plate 14, the cover glass 15, the dust-proof rubber main body 12a and the O-ring 12c are combined. Alternatively, in addition to the assembly structure described above, the holder 13, the light shielding plate 14 and the cover glass 15, and the dust-proof rubber body 12 a and In addition to the O-ring 12c, a set of assembly structures in which the CCD 16 is integrated in close contact is configured. An example of this set of assembly structures is shown in FIG. Here, a set of assembly structures including the CCD 16 is illustrated.

上記組立構造体の一部材となるホルダ１３の係止部１３ａをセンサマウントとなるＣＣＤマウント１８にねじ止め固定することにより、防塵ゴム本体１２ａとＯリング１２ｃとの間に、ホルダ１３、遮光板１４およびカバーガラス１５と、防塵ゴム本体１２ａおよびＯリング１２ｃが挟持された状態で、かつ、防塵ゴム本体１２ａがＣＣＤ１６に密着した状態で、Ｏリング１２ｃ、ホルダ１３、遮光板１４、カバーガラス１５、防塵ゴム本体１２ａ、およびＣＣＤ１６が、ＣＣＤマウント１８に固定される。   The locking portion 13a of the holder 13 which is a member of the assembly structure is screwed and fixed to the CCD mount 18 which is a sensor mount, so that the holder 13 and the light shielding plate are interposed between the dust-proof rubber body 12a and the O-ring 12c. 14, the cover glass 15, the dust-proof rubber main body 12 a and the O-ring 12 c are sandwiched and the dust-proof rubber main body 12 a is in close contact with the CCD 16, and the O-ring 12 c, the holder 13, the light shielding plate 14, and the cover glass 15. The dust-proof rubber main body 12 a and the CCD 16 are fixed to the CCD mount 18.

上記組立構造体の一部材となるホルダ１３をセンサマウントとなるＣＣＤマウント１８にねじ止め固定した後、ＣＣＤマウント１８をレンズマウント１１にねじ止め固定することにより、ＣＣＤカメラのマウント構造が完成する。   The holder 13 as a member of the assembly structure is screwed and fixed to the CCD mount 18 as a sensor mount, and then the CCD mount 18 is screwed and fixed to the lens mount 11 to complete the CCD camera mounting structure.

上記したように、防塵ゴム本体１２ａにＯリング１２ｃを一体に設けた防塵ゴム１２を構成し、さらに、この防塵ゴム１２を用いて、ホルダ１３、遮光板１４およびカバーガラス１５と、防塵ゴム本体１２ａおよびＯリング１２ｃとを一組にした組立構造体を構成し、または、この構成に加えて、防塵ゴム本体１２ａの他方の開口面部にＣＣＤ１６の撮像面１７の周部を嵌め込むことで、ホルダ１３、遮光板１４およびカバーガラス１５と、防塵ゴム本体１２ａおよびＯリング１２ｃとに加え、ＣＣＤ１６を密着状態で一体化した一組の組立構造体を構成して、この組立構造体をＣＣＤマウント１８に取り付ける構成としたことにより、部品点数を削減でき、かつ組立工程を著しく簡素化した、生産性の向上並びに製造コストの低減化に寄与できるマウント構造が提供できる。さらに、ＣＣＤマウント１８の取り付け工程を含む組立構造において、ＣＣＤ１６の撮像面を組立初期の段階で密閉構造とすることができ、これによって歩留まりのよい生産工程を構築できる。また上記した防塵ゴム本体１２ａにＯリング１２ｃを一体に設けた防塵ゴム１２を用いることで、一体化された防塵ゴム本体１２ａとＯリング１２ｃとの間で気密性の高い光路空間を形成できることから、撮像塵埃の飛散する環境下において長期に亘り安定した信頼性の高い撮像出力が可能となる。   As described above, the dust-proof rubber 12 is configured by integrally providing the dust-proof rubber main body 12a with the O-ring 12c. Further, the dust-proof rubber 12 is used to form the holder 13, the light shielding plate 14, the cover glass 15, and the dust-proof rubber main body. 12a and an O-ring 12c are combined into one assembly structure, or in addition to this structure, by fitting the peripheral portion of the imaging surface 17 of the CCD 16 into the other opening surface portion of the dust-proof rubber body 12a, In addition to the holder 13, the light shielding plate 14 and the cover glass 15, the dust-proof rubber body 12 a and the O-ring 12 c, a set of assembling structures in which the CCD 16 is integrated in close contact with each other is formed. The configuration attached to 18 contributes to the improvement of productivity and the reduction of manufacturing cost, which can reduce the number of parts and greatly simplify the assembly process. Mount structure that can can provide. Further, in the assembly structure including the mounting process of the CCD mount 18, the imaging surface of the CCD 16 can be a sealed structure at an early stage of assembly, and thereby a production process with a high yield can be constructed. Further, by using the dust-proof rubber 12 in which the O-ring 12c is integrally provided in the dust-proof rubber main body 12a, a highly airtight optical path space can be formed between the integrated dust-proof rubber main body 12a and the O-ring 12c. Thus, stable and reliable imaging output can be achieved for a long time in an environment where imaging dust is scattered.
