Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for assembling mechanical parts of an optical module, and more particularly to a jig used for press-fitting and crimping an LD element and an element holder.

[0002]

2. Description of the Related Art Conventionally, techniques in such a field include:
For example, there were the following. FIG. 2 is a view showing a press-fitting process of such a conventional LD element and element holder, and FIG.
FIG. 7 is a diagram showing a crimping process of the LD element and the element holder.

Conventionally, as shown in FIG. 2, in the process of press-fitting the LD element 1 and the element holder 2, the LD element 1 is placed on the lower dedicated jig 3 for press-fitting the element, which is fixed to the fixing base 4. on the other hand,
A rod 5 is implanted in the fixed base 4, and when the press 9 does not act, the rod 5 has a movable base 7 biased upward by a spring 6, and an element mounted on the movable base 7. Equipped with an upper dedicated jig 8 for press fitting,
The element holder 2 is placed in the upper dedicated jig 8 for press-fitting the element. Therefore, the LD element 1 is pre-positioned on the element holder 2 and then the element holder 2 is pressed from above by a press 9 to press the LD element 1 into the element holder 2.

Next, as shown in FIG. 3, in the step of caulking the element holder 2, the jig 11 dedicated to the lower part of the element caulking is fixed to the fixing base 4.
On the other hand, on the other hand, the jig 12 for exclusive use of the element caulking is provided on the movable table 7 side, and the LD element 1 press-fitted into the element holder 2 is
The element holder was set on the jig 12 for caulking the upper part, and pressure was applied from above the press 9 to crimp the element holder 2.

In this way, the step of press-fitting the element holder 2
The caulking process of the element holder 2 is a separate process using different jigs. That is, the press-fitting step (FIG. 2) was performed using the element press-fitting dedicated jigs 3 and 8, and the crimping step (FIG. 3) was performed using the element holder crimping dedicated jigs 11 and 12.

[0006]

As described above, in the conventional jig, the press-fitting step and the crimping step must be separately performed by using different jigs. Therefore, a dedicated jig is set in each step. Since the replacement has to be performed, the work is complicated, the cost is high, and there is a problem in managing each dedicated jig.

The present invention eliminates the above problems and simplifies the work and reduces the cost by performing the press-fitting process of the LD element and the device holder and the caulking process continuously without replacing the jig. An object of the present invention is to provide a method of assembling mechanical parts of an optical module and a device therefor.

[0008]

In order to achieve the above object, the present invention provides (1) a method of assembling mechanical parts of an optical module, wherein L
The step of press-fitting the D element and the element holder and the step of caulking the element holder to the LD element are continuously performed without exchanging the jig.

(2) In a device for assembling mechanical parts of an optical module, a press-fitting punch of an LD element arranged in the center of a fixed portion, a caulking punch capable of being raised and lowered by being guided by the press-fitting punch, and a caulking of an element holder. At the same time, an element clamp that can be retracted in the lateral direction as the caulking punch is lifted and an element holder clamp that is arranged above the element clamp are provided.

[0010]

The lower end surface 2 of the caulking punch 22 is attached to the upper surface of the spacer 23.
2b engage. That is, by moving the spacer 23 in the horizontal direction, the caulking punch 22 is guided by the press-fitting punch 21 and can move up and down.

On the other hand, an element clamp 31 is provided on the upper side, and a spring 33 is provided between the element clamp 31 and the support portion 32. A taper surface 31a that engages with the taper surface 22a of the caulking punch 22 is formed at the tip of the element clamp 31. Further, an element holder clamp 34 is arranged on the element clamp 31, and is configured to hold the element holder 2.

First, as shown in FIG. 1A, the LD element 1 is set in the press-fit punch 21 and the element holder 2 is set in the element holder clamp 34. After the setting is completed, the element holder 2 is press-fitted and fixed to the LD element 1 by pressing from above with a press (not shown). At that time, the tapered surface 31a of the element clamp 31 slides down on the tapered surface 22a of the caulking punch 22 and descends. At this time, the spacer 23 is moved to the left and the caulking punch 22 is lowered.

Next, as shown in FIG. 1B, the spacer 23 is moved to the right, the caulking punch 22 is raised, and the LD element 1 press-fitted into the element holder 2 is clamped by the element holder clamp 3.
Set to 4. Here, the tapered surface 22a of the caulking punch 22 engages with the tapered surface 31a of the element clamp 31, and the element clamp 31 retracts in the horizontal direction while compressing the spring 33. That is, by the next press, the tip end of the caulking punch 22 comes into contact with the lower end of the element holder 2 so that the element holder 2 can be caulked.

After the setting is completed, pressure is applied by a press from above, and the element holder 2 is caulked by the caulking punch 22.
As described above, the press-fitting step and the caulking step can be performed without exchanging the jig by only once setting the pressure by the continuous press. It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made based on the gist of the present invention, and these are not excluded from the scope of the present invention.
