Description

[0001] The present invention relates to a portable optical fiber cutting and grinding apparatus,

The present invention relates to a portable optical fiber cutting and grinding apparatus, and more particularly, to a portable optical fiber cutting and grinding apparatus which is portable and capable of cutting optical fibers and grinding work in a single apparatus, And more particularly, to a portable optical fiber cutting and polishing apparatus capable of shortening the time.

Background Art [0002] With the development of communication technology, optical fibers have been widely used as information transmission media.

However, the optical fiber connector used for connecting between the optical fibers generally has a structure in which the melted optical fiber is passed through and the ferrule is inserted and supported.

In order to minimize the reflection loss of the optical fibers contacting each other, it is important that the cross section of the optical fibers contacting each other be flat, so that the optical fiber on the contact surface must be cut flat and polished flat.

However, since the prior art polishing apparatus has various functions but is complicated in structure and is a heavy and large apparatus, it is difficult to carry it to the installation site, and in other conventional technologies, a portable optical fiber cutting apparatus is used at the work site, After cutting, the end face is polished using the portable polishing apparatus as shown in Fig. 1 (Japanese Patent Application Laid-Open No. 10-2011-5642).

However, such other conventional cutting and grinding apparatuses inconveniently require the operator to carry both the cutting apparatus and the grinding apparatus, because the cutting apparatus and the grinding apparatus are separately provided. In the portable grinding apparatus of Fig. 1, (Optical fiber connector) 200 is mounted and fixed. As shown in the cross-sectional view of FIG. 3, a structure in which the abrasive plate 210 eccentric to the rotation driving part 70 rotated by the motor 80 rotates and revolves And an abrasive paper 220 is attached to the upper portion of the abrasive plate 210.

Also, as shown in FIG. 2, the plurality of objects 200 are detachably fixed to the object to be fixed 130.

In polishing, first, the abrasive paper on the rough polishing surface is attached to the abrasive plate 210, and the jig body 110 is rotated about the hinge 122 to make the state as shown in Fig. After the elasticity is adjusted by rotating the motor 80, the motor 80 is operated to perform a rough polishing operation (rough polishing) for a predetermined time by the timer 50, and after replacing with the polishing pad 220 of a fine polishing surface, (Finishing polishing) is repeated.

Therefore, the portable polishing apparatus shown in FIG. 1 attaches the roughing abrasive paper in a state in which the jig 110 is spaced from one another at every polishing operation (FIG. 2), switches to the joined state (FIG. 1) 2, so that it is necessary to attach the finishing abrasive paper to the bonded state of FIG. 1 again to perform the finishing polishing. Therefore, the process of replacing the polishing films is complicated, time consuming, troublesome, It is quite inconvenient in terms of efficiency.

Further, since the polishing apparatus of Fig. 1 has no cutting function, it is inconvenient for the operator to cut the optical fiber by a separate cutting device.

SUMMARY OF THE INVENTION In view of the problems of the prior art of the present invention, there is provided a portable optical fiber cutting and polishing apparatus for carrying and cutting an optical fiber in a single apparatus.

According to an aspect of the present invention, there is provided a portable optical fiber cutting and polishing apparatus comprising:

The optical fiber cutting and polishing apparatus includes an upper main body (2) and a lower main body (1) rotatably engaged with each other;

The upper main body 2 includes a connector fastening portion 5 to which the optical fiber connector is attached and detached, a guide 21 which is engaged with the connector fastening portion 5 to guide the optical fiber 25 tightly, Has a first opening (24) that allows access to the body (1);

The lower main body 1 is provided with a scratch forming part 11 for scratching an optical fiber 25 that has been lowered through the guide 21 and an optical fiber 25 which is held by the optical fiber 25, A second opening 21 through which the cut optical fiber 25 is discharged; a roughing grinding device for roughly grinding the cut optical fiber 25; and a second grinding device 25 for grinding the roughly polished optical fiber 25 25);

The scratch is formed by the user moving the scratch forming part 11 horizontally, and the cutting is performed by the user such that the cutting part 12 is vertically moved in a direction opposite to the scratch;

When the upper main body 2 is rotated at a first angle with respect to the lower main body 1 in the state of the cut optical fiber 25, the rough polishing apparatus is automatically driven. When the upper main body 2 is further rotated at the second angle, Is driven.

Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings. 4 is a perspective view and a plan view of the optical fiber cutting and polishing apparatus of the present invention, respectively.

The upper body 2 is engaged with the lower body 1 by fastening the female screw structure 3 after inserting the upper body 2 through the male screw structure 4 extending from the lower body 1, do. At this time, an elastic spring (not shown) is provided inside the male screw structure 4 so that the elastic spring acts as a force pushing the upper body 2, so that the upper body 2 is in close contact with the lower body 1 . Then, the optical fiber connector is fastened to the connector fastening portion 5 and fixed.

As shown in Fig. 6, protruding type rotation hooks 23 are provided at intervals of 60 degrees on the upper edge of the lower main body 1, and an appropriate number of recesses (Not shown), so that the upper main body 2 comes into contact with the lower main body 1 and is rotated at an interval of 60 degrees when rotating.

4, when the upper main body 2 is detached from the lower main body 1, a rough polishing plate 6 for coarse polishing and a finishing abrasive plate 7 for fine polishing are formed on the lower main body 1, The roughing abrasive paper 8 and the finishing abrasive paper 9 are provided on the roughing abrasive plate 6 and the finishing abrasive plate 7, respectively, as shown in the left- And the roughing abrasive plate 6 and the finishing abrasive plate 7 are coupled eccentrically to the rotary shaft 36 (refer to the reference numeral 37 in FIG. 8), and the rotary shaft 36 is rotated by a motor (not shown) The rough polishing plate 6 or the finishing abrasive plate 7 is rotated and rotated together.

5, when the upper main body 2 is separated from the lower main body 1 by loosening the male screw structure 4, the upper main body 2 has a structure as shown in FIG. 5, And the lower right figure is a front view showing a procedure for placing the upper body 2 in the normal direction and engaging the parts and the upper right figure is a view showing the upper body 2 FIG.

Then, the connector fastening portion 5 for fastening the optical fiber connector is fastened first. Then, the guide 21 through which the optical fiber is closely contacted is engaged, and the connector fastening portion 5 and the guide 21 are fastened with the screw 22, .

In this case, three sets of connector fastening portions 5, a guide 21 and a screw 22 are shown in FIG. 5. In this case, only one connector fastening portion 5 may be present. However, If only the connector fastening part 5 exists and the connector fastening part 5 is broken when a plurality of optical fiber connectors are sequentially fastened to the connector fastening part 5 to perform cutting and polishing operations, It is inconvenient to replace the connector fastening portion 5 or to replace the upper main body 2. Therefore, if the three connector fastening portions 5 are provided, the two connector fastening portions 5 are redundant, So that there is no inconvenience of replacing the part (5) or replacing the entire upper body (2).

Next, the lower main body 1 has a structure as shown in Fig. 6, wherein a lower left side view of Fig. 6 is a perspective view, a left upper side is a plan view, and a right side view is an exploded view of parts. At this time, the opening 14 is a space for installing the rough polishing apparatus and the finishing abrasive apparatus, and these are omitted for simplification of the drawing.

6, a scratch forming portion 11 and a cut portion 12 are provided on the upper portion of the lower main body 1. In FIG. 7, only the scratch forming portion 11 and the cut portion 12 are enlarged. 7 is a perspective view, and a right upper portion is a plan view and a lower right portion is a front view.

Now, the operation of the flaw forming portion 11 and the cut portion 12 will be described in detail with reference to Fig.

The optical fiber 25 of the optical fiber connector coupled to the connector fastening portion 5 passes between the wings 16 of the clamp structure 15 via the guide 21 and the knob 17 whose lower portion is elliptical 90 degrees so that the corresponding portion 19 of the clamp structure 15 is opened to overcome the force of a spring (not shown) which acts to wing the wings 16 and the wings 16 are narrowed to hold the optical fiber tightly . Of course, if the knob 17 is turned again by 90 degrees so that the corresponding portion 19 of the clamping structure 15 is narrowed, the wings 16 are opened and the optical fiber 25 is loosened.

When the optical fiber 25 is held in this state, the distal end portion 27 of the flaw forming portion 11 is fitted in the safety catching jaw 26, and the cut portion 12 is prevented from moving up and down, 11 are horizontally retreated to the left so as not to be in the same state as the upper right figure of FIG. 7, so that the cutting portion 12 is prevented from moving downward, so that cutting (which will be described immediately below) It is possible to prevent the scratch forming section 11 from operating after changing the order so that the cut section 12 is operated to cut off.

When the lever 20 is moved horizontally to the left, the state is as shown in the right upper portion of Fig. 7, and as the disc cutter 18 (with a sharp blade at its edge) horizontally moves to the left, the optical fiber 25 Thereby forming horizontal scratches. Of course, in this state (the state of upper right in Fig. 7), the distal end portion 27 is missing from the safety catching jaw 26, so that the cut portion 12 is movable downward.

7, the upper portion of the optical fiber 25 is held in close contact with the guide 21 and the lower portion of the optical fiber 25 held by the clamping structure 15 is inserted into the cut portion 12, The optical fiber 12 is moved in the opposite direction to the flawed portion, so that the optical fiber is easily cut and the cut surface is cut flat. This is the same principle as cutting a straight line with a diamond knife from the top of the glass plate, holding it on both sides and folding it down, and cutting the cut surface smoothly.

The lower portion of the cut optical fiber 25 falls down through the small opening 28 in the upper left figure of FIG. 6 and is collected in the lower waste collection bin (not shown).

At this time, it is preferable to use a linear bearing so that the flaw forming portion 11 and the cut portion 12 can be perfectly linearly moved.

When the disc cutter 18 is repeatedly used, the portion in contact with the optical fiber is worn out and the contact portion can no longer be used. Therefore, the angle of the upper surface of the disc- After the disk cutter 18 is detached and the angle is changed and fixed again, a new cutting portion is formed on the optical fiber 18, The cutter 18 can be used for a considerably long period of time.

Next, a rough polishing apparatus or finishing apparatus provided in the opening 14 (corresponding to the opening 34, 35 in FIG. 8) of the lower main body 1 in FIG. 6 will be described in detail with reference to FIG. 8 .

The left side of FIG. 8 shows a roughing / finishing abrasive machine 31 which is installed in the openings 34 and 35 and is driven by a motor (not shown) installed inside the lower main body 1 The abrasive plates 6 and 7 which are eccentrically and rotatably mounted on the rotary plate 37 which is fixed to the rotary shaft 36 are driven by a rotary shaft 36 ) In accordance with the rotation of the rotor. An MCU (Micro Control Unit) for controlling the electric parts such as the motor is present in the lower main body 1. Further, abrasive paper 8, 9 for roughing or finishing is attached on the abrasive plates 6, 7.

Now, the cutting and polishing process according to the present invention will be described in detail with reference to the structural views of FIGS. 4 to 8 and the process diagram of FIG. Here, the upper diagram corresponding to each step shows the positional relationship between the lower main body 1 and the upper main body 2 at the corresponding stage, and the drawings relating to steps (S1) to (S5) (S6) to step S8 show the positional relationship between the scratch-forming portion 11 and the cut-out portion 12 in the upper main body 1 and the position of the upper main body 2 relative to the lower main body 1 Relationship.

The lower bar graph shows the rotation angle of the upper main body 2 with respect to the lower main body 1 at each step.

6, the projecting-type rotation stopping jaw 23 of the lower main body 1 of Fig. 6 is moved in the same direction as the upper side of Fig. It is caught by the concave portion of the main body 2 and is in a state of not rotating well. This starting point is indicated by the angle 0 in the lower bar graph of FIG. In this state, the distal end portion 27 of the flaw forming portion 11 is fitted in the safety catching jaw 26. [

Now, the optical fiber connector is fitted to the connector fastening part 5 (connector mounting step S1). Then, the optical fiber 25 moves downward between the wings 16 in a downward direction closely to the guide 21.

Then, by turning the knob 17, which is elliptical in the lower part, with a finger through the opening 24 in Fig. 4 by 90 degrees and causing the corresponding part 19 of the clamping structure 15 to open, the wings 16 (Optical fiber clamping step S2) (refer to the optical fiber 25 in the upper right-hand drawing of Fig. 7) by the force of the spring (not shown) that acts to pull the wings 16 narrow.

7, when the lever 20 is moved horizontally to the left, the disc cutter 18 is horizontally flawed on the optical fiber 25 (scratch forming step S3).

7, the upper portion of the optical fiber 25 is held in close contact with the guide 21 and the lower portion of the optical fiber 25 held by the clamping structure 15 is removed from the cut portion 12 move the optical fiber 25 in a direction opposite to the portion of the optical fiber 25 that has been scratched, so that the optical fiber is easily cut and the cut surface is cut flat (optical fiber cutting step S4).

When the knob 17 is further rotated by 90 degrees to narrow the corresponding portion 19 of the clamping structure 15, the wings 16 are opened to release the optical fiber so that the lower portion of the cut optical fiber 25 6 through the small openings 28 of FIG. 6 and then discharged to a collection tube (not shown) at the bottom (optical fiber waste discharge step S5).

Then, the cutting portion 12 is moved upward to return to the original state, and the distal end portion 27 of the flaw forming portion 11 is fitted in the safety catching jaw 26.

When the user rotates the upper body 2 in the clockwise direction by 120 degrees with respect to the lower main body 1 in this state, the protruding rotation jaws 23 of the lower main body 1 again correspond to this It is caught by the concave portion of the upper main body 2 and is not rotated well.

 When this state is reached, the lower sensor (for example, infrared sensor, limit switch, etc.) is detected to reach this point, and the motor is driven to perform rough polishing as rough polishing for a predetermined time set by the timer, (The rough polishing step S6). At this time, 120 degrees of the lower bar graph of FIG. 9 indicates the rough polishing step.

In the same manner as the rough polishing step S6, when the user rotates the upper main body 2 again in the clockwise direction at the position of the rough polishing step S6, the finish polishing step S7 is automatically performed.

Next, in this state, when the user rotates the upper main body 2 clockwise again by 60 degrees with respect to the lower main body 1, the protruding type rotation jaws 23 of the lower main body 1 again move to this position So that it is caught by the concave portion of the corresponding upper main body 2 and does not rotate well.

  In this state, the optical fiber connector fitted to the connector fastening portion 5 is separated (unclamping), and the abrasive powder on the abrasive paper is cleared at this position. This step is an unclamping and clear step S8.

Next, in this state, when the user rotates the upper main body 2 clockwise again by 60 degrees with respect to the lower main body 1, the user returns to the original state to return to the protruding rotary jaws 23 is caught by the concave portion of the corresponding upper main body 2 and does not rotate well, and if step S8 is performed in the above-mentioned steps S1 to S8 for another optical fiber connector, Cutting and polishing are performed.

As a result, when the optical fiber cutting and grinding apparatus of the present invention as described above is used, the optical fiber cutting and grinding operations are performed in one apparatus, and the cutting and grinding operations of the optical fiber are conveniently performed in the field, I will.
