Description
【発明の詳細な説明】 「産業上の利用分野」 本発明は、ボールレンズの無反射膜コーティングおよび
ボールレンズの保持体およびボールレンズの装着方法に
関するものである。TECHNICAL FIELD The present invention relates to a non-reflective film coating for a ball lens, a holder for the ball lens, and a method for mounting the ball lens.

物理蒸着（PVD）による無反射膜をコーティングさせて
いる。“Problems to be Solved by Conventional Techniques and Inventions” As shown in FIG. 11, the ball lens 101 has an epoxy resin 1 directly attached to an LED chip 104 having a light emitting portion 103 built in on a substrate 102.
As shown in FIG. 12, the ball lens 111 is attached to one end face of the elongated cylindrical body 112 as an optical communication connector, and the optical fiber 113 is connected to the other end side thereof. Then, the outer peripheral surfaces of these ball lenses 101 and 111 are coated with a non-reflective film by physical vapor deposition (PVD) such as vacuum vapor deposition, sputter vapor deposition, and ion plating.
ボールレンズは球体であるため、保持しにくく、無反射
膜を全面にわたってコーティングするのは困難である。
それで、通常、第13図に示すように、ボールレンズ121

着がなかなか困難であって、内面側は無反射膜が形成で
きにくく、外面側のみに無反射膜が形成される。Since the ball lens is a sphere, it is difficult to hold it, and it is difficult to coat the antireflection film over the entire surface.
So, normally, as shown in FIG. 13, the ball lens 121
Is placed on the end surface of the holder 122 of the cylindrical body and coated with a non-reflective film, but if the diameter is too long with respect to the inner diameter of the holder 122, vapor deposition on the surface of the ball lens 121 in the holder 122 is difficult. However, it is difficult to form the antireflection film on the inner surface side, and the antireflection film is formed only on the outer surface side.

量生産では多種類のホルダを用意せねばならず生産量の
変動のある生産には不向きである。Further, since the coating of the antireflection film on the ball lens is batch-processed, it becomes expensive when the number of processes is small, and further, when the support for the ball lens is large, it becomes expensive when the number of ball lenses to be processed is small. Also, in the case of high-mix low-volume production, many types of holders must be prepared, which is unsuitable for production in which the production volume varies.

ルレンズの自動供給ができにくい。Furthermore, the ball lens coated with a non-reflective film is 1
Since they are individually separated, it is difficult to apply them to an automatic machine and it is difficult to automatically supply ball lenses.

装着するようにしたものである。“Means to be Solved by the Invention” In view of the above circumstances, the present invention allows a ball lens to be fitted into a large number of mounting holes that have been drilled to hold the ball lens in a seat member, and the surface of the held ball lens. In order to prevent the ball lens from falling off on the seat member whose ball lens surface is coated with a non-reflective film by holding the ball lens in a number of mounting holes and holding it. A protective sheet is attached so that it is sandwiched, and a ball lens coated with a non-reflective film that is held in the mounting hole of the sheet member is placed facing the mounted member, and the ball lens is pressed by the pressing member to be mounted. The member is continuously mounted on the member by an automatic machine.

プ状に形成できる。[Example] As shown in Fig. 1, the diameter of the ball lens 2 is a sheet member made of an elastic material such as a metal plate such as stainless steel or an iron plate or a heat-resistant plastic, which can withstand the temperature of 200 ° C at the time of anti-reflection coating. When a ball lens is fitted into it with a slightly smaller diameter, a plurality of mounting holes 2 are formed so that the peripheral edge bends and is held by an elastic body, so-called caulking. next,
As shown in FIG. 2, the ball lens 3 is pressed into the mounting hole 2 of the sheet member 1 and is fitted into the mounting hole 2 as shown in FIG. At this time, the periphery of the mounting hole 2 engages with the equatorial plane of the ball lens 3 and bends to fit the ball lens 3 by caulking. Only the equatorial plane of the ball lens 3 is in contact with the periphery of the mounting hole 2. A large number of sheet members 1 holding the ball lens 3 are housed in a furnace, and vacuum deposition, sputter deposition,
A non-reflective film is attached by physical vapor deposition (PVD) such as ion plating. The sheet member 1 is shown in FIG.
It can be formed into any tape shape that is convenient for use as shown in FIG.

Stick the protective sheet 4 such as vinyl. The protective sheet 4 prevents the ball lens 3 from falling off and prevents the ball lens 3 from being soiled. In addition, as shown in FIG. 7, an adhesive layer 5 is provided at the end of the protective sheet 4 so that the ball lens 3 is not contaminated when the protective sheet 4 is attached. Further, as shown in FIG. 8, in order to prevent the ball lens 3 held by the sheet member 1 from falling off and becoming dirty, both sides of the shyt member 1 can be covered with a vacuum pack 6.

性が向上する。[Advantages of the Invention] The present invention includes a step of fitting a ball lens into a large number of mounting holes formed in a seat member to hold the ball lens in the seat member, and an antireflection film on the surface of the ball lens held in the seat member. Since it is a ball lens anti-reflective film coating method that consists of a coating process, it is possible to coat an anti-reflective film on the entire surface of the ball lens except the equatorial plane of the ball lens. Although it was difficult to coat the entire circumferential surface due to the use of tools, it is possible to coat a non-reflective film on almost the entire circumferential surface of the ball lens. The anti-reflection film coating process on the ball lens has hitherto been a batch process, but according to the present invention, a large amount of process is possible and the productivity is improved.

供給することが可能となる。Further, according to the present invention, a ball lens is held by fitting and holding a ball lens in a plurality of mounting holes, and attaching a protective sheet to a sheet member having a ball lens surface coated with an antireflection film so as to hold the ball lens. Since it is a body, ball lenses with non-reflective film attached to them could not be supplied to automatic machines one by one.
Since a plurality of ball lenses can be collectively held by one holder, the ball lenses can be continuously supplied to the automatic machine.

様の効果を発揮し、無反射の機能を十分に果たす。Further, according to the present invention, a ball lens, which is held in a mounting hole of a sheet member and coated with a non-reflective film, is arranged to face the mounted member, and the ball lens is pressed by a pressing member arranged on one side of the sheet member. The ball lens can be automatically attached to the attached member by an automatic machine. Further, since the ball lens is moved in parallel by the pressing member and mounted on the mounted member, the equatorial surface of the ball lens on which the non-reflective film is not adhered is the mounting portion of the mounted member. The lens exerts the same effect as coating a non-reflective film over the entire peripheral surface, and sufficiently fulfills a non-reflective function.
