本発明は、レーザー集光用レンズ、カメラレンズ等のレ
ンズと、このレンズを保持するだめのレンズ鏡胴とを一
体的に係止する成形方法に関するものである。Detailed Description of the Invention (Industrial Field of Application) The present invention is directed to a molded product that integrally locks a lens such as a laser condensing lens or a camera lens and a lens barrel that holds the lens. It is about the method.
（従来例の構成とその問題点）
従来、レンズとレンズ鏡胴とは個別の部品として製作し
、レンズの性能をそこなうことなく、レンズ鏡胴内部に
ねし止め、または接着によりレン゛ズを固定している。(Conventional structure and its problems) Conventionally, the lens and lens barrel were manufactured as separate parts, and the lens was attached to the inside of the lens barrel by screwing or gluing, without impairing the performance of the lens. Fixed.

ンズ鏡胴内部への組み込み固定の工程を経て、レンズと
レンズ鏡胴とが一体化される。For example, in an injection molded lens using resin, after the lens is molded, it is removed from the mold, the molded sheet is cut, the lens surface is coated with anti-reflection coating, and the lens is assembled and fixed inside the lens barrel. Through the process, the lens and lens barrel are integrated.
一般的な樹脂材料を用いたレンズの欠点は、その硬度が
低いため、上記のような長い工程中にレンズ面に傷をつ
けやすく、レンズの性ｒ１ヒを劣化させるだけでなく、
製品としての価値も低下させる。The disadvantage of lenses made of general resin materials is that their hardness is low, so the lens surface is easily scratched during the long process mentioned above, which not only deteriorates the properties of the lens, but also
It also reduces the value of the product.
さらに、レンズ鏡胴内へ組み込むときに、レンズ光軸と
レンズ鏡胴の中心軸を精度よくあわぜて、固定すること
が大切である。どちらか一方の精度が悪いと、光軸を合
わせるだめの調整機構が必要となる。特に２枚以上の組
み合わせレンズの場合には、レンズ間の光軸も精度よく
同１抽上に合わせなければならない。Furthermore, when assembling the lens into the lens barrel, it is important to precisely align and fix the lens optical axis and the center axis of the lens barrel. If the accuracy of either one is poor, an adjustment mechanism will be required to align the optical axis. In particular, in the case of a combination of two or more lenses, the optical axes between the lenses must also be precisely aligned with the same abstraction.
第１図ないし第３図は、従来のレンズとレンズ鏡胴との
関係を示す断面図である。1 to 3 are cross-sectional views showing the relationship between a conventional lens and a lens barrel.

になる。In FIG. 1, a convex portion 3 for lens positioning is provided on an inner surface 2 of a lens barrel 1, and a lens 4 is supported by the convex portion 3 and the inner surface 2 of the lens barrel. In this case, the lens optical axis 5 and the central axis 6 of the lens barrel 1 substantially coincide. However, due to variations in the outer diameter of the lens 4 and variations in the dimensions of the inner surface 2 of the lens barrel 1,
Furthermore, if the orthogonality of the convex portion 3 to the lens barrel center axis 6 is poor,
The relationship between the lens optical axis 5 and the lens barrel center axis 6 is as shown in FIG.

で示すように、レンズ４の光軸５およびレンズ７の光軸
８とレンズ鏡胴の中心軸６との関係がばらばらになり、
組み合せレンズとしての機能が極めて悪化する。Unfortunately, if the manufacturing accuracy of the lens barrel 1 is HHs, the relationship between the optical axis 5 of the lens 4, the optical axis 8 of the lens 7, and the central axis 6 of the lens barrel will be inconsistent, as shown in FIG. Become,
The function as a combination lens becomes extremely poor.

ることはできない。In the case of Fig. 2, it is possible to align the optical axis of the lens with the device using the adjustment mechanism described above, but in the case of a combination lens as shown in Fig. 3, lenses 4 and 7 and the lens mirror can be aligned. Unless the accuracy of each part of the cylinder 1 and the assembly accuracy are improved, it is! It is not possible to obtain a lens with performance that is just 1% better.

なる欠点があった。For example, if the optical axes do not match as shown above,
With a laser focusing lens, the laser beam cannot be focused on a single predetermined point, which is fatal to the performance. There was a drawback that as the outer diameter of the lens became smaller, assembly and fixing operations became more difficult.

うに同じ結果が得られる。As shown in the figure, after the lens barrel 28 is placed in a predetermined position and the mold is clamped, the lens material injected by the injection nozzle 32 is transferred to the sprue 33, the runner 34, and the mold.
-1-35 and a through hole 31 arranged on the side of the lens barrel 28
Then, a predetermined amount is injected into the internal space formed by the inner surface of the lens barrel 28, the movable lens surface 13, and the fixed lens surface 14, and is cooled and solidified. After opening the mold, use Niziefthalorado 23 to increase Nizieffugrate 18. Work 9, the lens barrel 28 with the Enoex taken out, the lens 37 on the sprue 33,
It is taken out together with the runner 34. At that time, the lens 37 is tightly packed and fixed into the inner surface of the lens barrel 28 and the +A through hole 31, and even if the sprue 33, runner 37I and cut-off 1 are made afterwards, the lens 37 and the lens barrel] The positional relationship with 28 does not change. In this embodiment, the cylindrical lens (.1) was injected through one through-hole, but the same result can be obtained even if it is injected through a plurality of through-holes, as shown in FIG.
