Conventionally, such a second component such as an objective lens and a beam splitter has been bonded to a first component such as a chassis with an adhesive. Therefore, the second component such as the objective lens and the beam splitter is applied with a certain amount of adhesive so that an error such as a tilt or a displacement does not occur due to the amount of the applied adhesive or the like. It is important to adhere to the first component quickly. Conventionally, when such a second component is mounted on a first component such as a chassis, an automatic bonding device that automatically applies an adhesive and bonds accurately and quickly has been used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the automatic bonding apparatus according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of the automatic bonding apparatus according to the present invention.

As shown in FIG. 1, an automatic bonding apparatus according to the present invention is a main body 1 of an apparatus for automatically applying an adhesive to a chassis (not shown) of an optical head to bond a lens (not shown).
A rotary table 2 rotatably mounted on the upper surface of the main body 1; a plurality of mounting portions 3 for mounting a chassis on the upper surface of the rotary table 2;
The apparatus includes an applicator 4 provided on the upper surface of the outer main body 1 for applying an adhesive, and a UV (ultraviolet) irradiator 5 for curing the adhesive applied by the applicator 4.

Here, the main body 1 is formed in a box shape, and has an opening for installing the rotary table 2 on the upper surface. A rotary table 2 formed in a circular shape is mounted in this opening so as to be rotatable in the direction of the arrow shown in FIG.

The rotary table 2 is switched between a rotation every 72 ° and a rotation every 144 ° by an index device (not shown) as a rotating means provided inside the main body 1. It is provided to rotate.
This index device operates by being operated by a switch (not shown) of a control panel provided on the main body 1. On the upper surface of the turntable 2, a plurality of installation portions 3a, 3b, 3c, 3d, 3e for installing the chassis are provided. The installation portions 3 are provided at five locations at the center on a line obtained by radially dividing the outside of the upper surface of the turntable 2 into five from the center.

Thus, when the rotary table 2 is rotated every 72 ° as described above, the rotary table 2 is rotated at intervals at which the installation section 3 is formed. That is, the rotating table 2 is, for example,
When c repeats the rotation every 72 ° from the predetermined position five times,
After one rotation (360 °), the installation section 3c returns to the predetermined position again.

When the rotary table 2 is rotated every 144 °, the installation units 3 are rotated at every other interval. Therefore, when the installation section 3c repeats the rotation every 144 ° five times from the predetermined position, the turntable 2 rotates twice (720 °).
Then, the installation section 3c returns to the predetermined position again.

On the outside of the rotating table 2 which rotates in this manner, the coating machines 4 and U mounted respectively on the upper surface of the main body 1 are provided.
A V (ultraviolet) irradiator 5 is provided. The coating machine 4 is shown in FIG.
Is attached to the other end of the main body 1 facing the operator. The coating machine 4 is formed so as to apply an adhesive for bonding a lens to a chassis.

The UV irradiator 5 is provided at an angle (72 °) where the rotary table 2 is divided into five equal parts from the coating machine 4 (the position of the installation section 3a shown in FIG. 1). This UV
The irradiator 5 is formed to irradiate UV (ultraviolet) in order to cure the adhesive applied to the chassis by the applicator 4.

When the lens is fixed to the chassis by the automatic bonding apparatus according to the present invention thus formed, there are two methods as in the conventional automatic bonding apparatus shown in FIGS. First, the first method is to apply the adhesive by the applicator 4 after attaching the lens to the chassis of the optical head,
This is a method of curing with a UV irradiator 5. In this method, first, the worker 6 mounts a lens on the chassis of the optical head and sets the lens on the installation section 3c. When the chassis is set on the installation section 3c, the turntable 2 rotates by 72 °. Thereby, the chassis moves to the position of the installation part 3d shown in FIG. 1 and stops for a certain time. After the chassis stops at the position of the installation part 3 d for a certain period of time, the turntable 2 further rotates by 72 ° and moves to the lower part of the coating machine 4. The adhesive moved to the lower portion of the coating machine 4 is applied to the side end of the lens mounted on the chassis by the coating machine 4.

When the adhesive is applied to the chassis, the rotary table 2 is further rotated by 72 ° and the chassis is moved to the lower part of the UV irradiator 5. Thus, the UV irradiator 5 irradiates the adhesive applied to the side end of the lens with UV to cure the adhesive. Thus, the lens is fixed to the chassis by curing the adhesive. Thereafter, the turntable 2 is further moved to 7
By rotating by 2 °, the operator 6 collects the chassis at the position of the installation section 3b shown in FIG.

On the other hand, the second method is a method in which an adhesive is applied to the chassis of the optical head by the applicator 4 and then the lens is mounted and cured by the UV irradiator 5. In this method, first, the worker 6 sets the chassis of the optical head on the installation section 3c shown in FIG. When the operator 6 sets the chassis on the installation part 3c, the turntable 2 rotates 144 ° and stops for a certain time. Thereby, the chassis moves to the lower part of the applicator 4, and the applicator 4 applies the adhesive to a predetermined portion of the chassis.

When the adhesive is applied to the chassis, the turntable 2 is further rotated by 144 °, and the mounting portion 3b shown in FIG.
Move to the position. Here, a lens is mounted on the chassis by the worker 6. When the lens is mounted on the chassis, the turntable 2 further rotates by 144 °, moves the chassis to the position of the installation section 3d shown in FIG. 1, and stops for a certain time. After the chassis stops at the position of the installation part 3d for a certain period of time, the turntable 2 further rotates by 144 ° and moves to the lower part of the UV irradiator 5. Thereby, the UV irradiator 5 cures the adhesive and fixes the lens to the chassis. As described above, when the adhesive is hardened on the chassis and the lens is fixed, the turntable 2 further rotates by 144 ° and stops at the position of the installation portion 3c shown in FIG. Thereby, the worker 6
Collects the chassis to which the lens is fixed, and ends.

Here, in the automatic bonding apparatus according to the present invention, the operation in which one chassis is installed in the installation section 3c and executed in the order of operation has been described in the above description of the operation, but in the actual process, all the installation sections 3a, The chassis of the optical head is installed at 3b, 3c, 3d, and 3e, and operations such as application of an adhesive, mounting of a lens, UV irradiation, and setting of the chassis are performed in parallel.

For example, although the operation of loading and unloading the chassis of the optical head is performed by the operator at the installation section, the present invention is not limited to this. It is also possible to provide automatic transfer means for automatically loading or unloading. Further, the embodiment in which the upper surface of the turntable 2 is divided into five and the installation portions 3a, 3b, 3c, 3d, and 3e are provided in the vicinity of the outer periphery has been described, but the present invention is not limited to this. It is also possible to provide an apparatus for bonding and curing two or more parts at a time by providing an installation part by dividing the number by an odd number or more. In addition, although a UV-curable adhesive was used for the applicator 4, the present invention is not limited to this. For example, by using the UV irradiator 5 as a primer applicator, a heater, a press, and a dryer, Each can be applied as a coating machine using a primer-curable, heat-curable, pressure-sensitive, or impression-curable adhesive. Further, the embodiment of the automatic bonding apparatus for bonding the lens to the chassis of the optical head has been described. However, the present invention is not limited to this. For example, an assembly in which solder is applied to a circuit board and predetermined electronic components are mounted. Application to a machine is also possible.
