A light emitting element P is located above the lens L on the jig table 1 by a handling arm H, light rays emitted from the light emitting element P are made to irradiate a TV camera provided under the jig table 1 passing through a through-hole 9, and the light emitting element P and the lens L are aligned with each other in optical axis through an image processing by the TV camera, and the optical element P is arranged on an adequate position above the lens L through the handling arm H. The optical element P arranged at the adequate position above the lens L is bonded to the lens L with adhesive agent or the like, and this combined structure is separated to dismount with a force defeating the adhesive force of the adhesive rubber sheet 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a jig for assembling an optical circuit component set f=j, and in particular to a jig for assembling an optical circuit component assembly consisting of a combination of a light emitting element and a lens. This relates to a jig for Nj drilling.

(Prior Art) Optical circuit components that use light-emitting elements such as light-emitting diodes (LEDs) and semiconductor lasers (LDs) are equipped with a Fresnel light-emitting element and a Fresnel light-emitting element to prevent the light emitted from the light-emitting element from diffusing. It is known that the lens is configured in combination with a lens such as a lens.

To assemble the light-emitting element and lens, use the lens as a dedicated assembly.
The light emitting element is fixed to the Jig jig, the light emitting element is handled against the lens fixed to the Jig jig, the optical axis alignment of the lens and the light emitting element is performed, and the two are bonded together. This is done by bonding using an agent or the like.

” - The above-mentioned group (= conventionally known a used for J-setting, (= Jig for J-setting is designed to fix the lens on the mounting jig with a pressure spring, or The lenses are fixed on the set f=J jig by suction by pressure.

(Problem to be Solved by the Invention) In the case of the presser spring type, it is necessary to insert the lens between the presser spring and the assembly jig -1- surface, which makes loading work difficult. It becomes a nuisance. On the other hand, a negative pressure suction type does not cause such a problem, but requires a negative pressure generator and a negative pressure control circuit, making the device bulky.

Also, in any case, group 1 = J jig is metal, glass,
It is composed of a rigid body such as synthetic resin, and therefore the lens and #
I (=I scratches on the lens due to contact with jig f=-
However, the optical characteristics of the lens may be impaired. In view of the above-mentioned problems with conventional jigs for testing optical circuit components, the present invention has been developed to simplify the structure, allow lens loading, and prevent damage such as scratches to the lens. Our aim is to provide a jig for J-setting.

(Means for Solving the Problems) -1- The object as described above is, according to the present invention, to provide a jig for assembling an optical circuit component constituted by a light-emitting element and a lens. , a jig stand that holds the lens for bonding the light emitting element r to the lens is shown in white; #l of an optical circuit component characterized by 1. being configured to adhesively hold 1 nons by adhesive force]
, i-J' I: + Caution l-L.

(Function) According to the above-described structure, since the lens holding surface is made of adhesive rubber, the lens is held adhesively by the slate force of the adhesive rubber. This will not damage the lens.

(Example) The present invention will be described in detail below with reference to the attached figure (=J).

1 to 3 show one embodiment of a jig for picking up optical circuit components according to the present invention. The jig for picking 1 has a jig stand 1 made of metal, glass, synthetic resin, etc., and an adhesive rubber sheet 3 is attached to two sides of the jig stand 1. The adhesive rubber sheet 3 is made of gel-like adhesive rubber known as Gel Pack (trade name).

In this embodiment, the jig stand 1 is designed to assemble four optical circuit components at the same time, and for this purpose, there are four positions on the adhesive rubber sheet 3 for positioning the lens L. A pin 5 and a plate spring 7 are provided. Incidentally, if the positioning of the lens L on the jig is appropriately performed by handling the lens L with respect to the jig, the positioning pins 5 and presser springs 7 may be omitted altogether.

Through holes 9 for optical axis alignment are provided in the jig table 1 and the adhesive rubber sheet 3 at the position of each lens L arrangement stage.

The lens L is, for example, a deck-shaped Fresnel lens, which is placed on the adhesive go-sheet 3'' by suitable handling means. Lens L is sticky go, sheet 31. When placed on the jig table 1, the lens L is held adhesively against the jig table 1 by the adhesive force of the adhesive rubber sheet 3.

The light emitting element P is mounted on the jig stand 11 by the handling arm H.
is brought onto the lens L of the light-emitting element P, and by the light emission of the light-emitting element P itself, the light beam of the light-emitting element P is irradiated onto the television camera TV through the through hole 9 by the television camera TV provided at the bottom h' of the jig table 1, Through image processing, the luminescent element rP and lens L
Optical axis alignment is performed with the Hunt Ringer 1-
1H, the optical elements r and P are placed at appropriate positions on the lens holding surface.

The optical element P placed in the proper position of the lens LL is adhered to the lens L using an adhesive or the like, and after this adhesion is completed, the combined structure of the lens L and the light emitting element P is bonded by the adhesive rubber sheet 3. It is easily removed by peeling off with a force that overcomes the force.

(Effects of the Invention) As can be understood from the above explanation, in the jig for assembling an optical circuit component according to the present invention, the lens holding surface is made of adhesive rubber, so that the lens is The adhesive force of the adhesive rubber holds the lens in place, and by simply placing the lens on the adhesive rubber, filling the lens into the jig is completed. Once removal is complete, the rubber-like elasticity of the adhesive rubber prevents damage to the lens, and allows for safe assembly into the structural tube. Become.
