It relates to an optical fiber processing apparatus that can be performed sequentially in one device.

In general, an optical fiber is a fiber-shaped waveguide for transmitting light, and is used in the form of an optical cable, which is bundled in several strands, and may be made of synthetic resin, but mainly made of glass having high transparency. The optical fiber is composed of a double cylinder structure by a core and a cladding surrounding the core, and the cylinder is formed by covering the cylinder 2-3 times with synthetic resin.

As a result of the instantaneous operation, the coating of the optical fiber subjected to high temperature heat as shown in FIG. 9A is converted into a gaseous state into a gaseous state by being provided with a heat deflection temperature in a very short time as shown in FIG. 9B. The change expands the volume of the inner covering and expands the outer covering.

Thereafter, the outer sheath is pushed out from the outer surface of the optical fiber by the hot air of the heater in the expanded state, as shown in FIG. 9C, so that the sheath of the sheath is carried out, as well as the ejection direction of the hot air blows down from above. The sheath is removed cleanly.

On the other hand, the coating properties of the optical fiber are not constant, and the coating removal temperature needs to be varied according to external conditions. If this problem is not preceded, a problem arises in that the coating is pressed onto the optical fiber, and the present invention changes the temperature arbitrarily by the temperature control button 24b and the temperature control display LED 24c in the control panel 24. It is also possible to check the variable state with the naked eye, so the response to this is excellent.

In addition, according to the present invention, the exhaust port 12 and the exhaust fan 14 are formed in the base 10 to filter out and remove odors and smoke caused by the removal of the coating, and continuously exhaust the outside to improve the environment of the workplace. Can be.

On the other hand, when the stripping and removal (washing) of the coating is completed, the clamp means 30 is returned to its original position (horizontal state) and the position is moved in the opposite direction through the sliding guide 26 to prepare for cutting. To get there. That is, the optical fiber clamped to the clamp means 30 is positioned above the cutter 45 of the cutting means 40.

Thereafter, the cutting operation of the optical fiber is started. When the worker presses the cover 48 further, as shown in FIGS. 4A to 4C, the cover 48 is formed of the elastic member 44a of the press means 46. The upper stopper 44e is lowered while overcoming the elastic force. The upper stopper 44e lowers the lower stopper 44c while overcoming the elastic force of the elastic member 44d. Therefore, the slider 43 is advanced by the expansion force of the elastic member 44a, and the cutter 45 mounted on the slider 43 scratches the optical fiber 1. At this time, the plunger stopper 46c is supported on the protrusion 44f of the slider 43, that is, maintained in the raised state.

Since the slider 43 advances instantaneously in the raised state of the plunger 46b, the plunger stopper 46c is no longer supported by the projection 44f. Therefore, the plunger 46b integrally formed with the plunger stopper 46c is instantaneously lowered by the elastic force of the elastic member 46a. In the lowering operation of this plunger 46b, the scratched optical fiber 1 is cut completely. This completes the one-step work for stripping, cleaning and cutting the fiber.

The operating state of another embodiment of the optical fiber processing apparatus according to the present invention has many similarities to that of one embodiment.

That is, the operation of clamping the optical fiber 1 to the finger base 330 seating groove 330a of the clamp means 300 prior to the operation of the device and applying power through the control panel 240 (power switch 240a) Supplying the air of the air generator 200 to the heater 220, while controlling the temperature (temperature control lever 240b) so that the hot air is discharged from above through the hot air outlet 220a of the heater 220 Same as one embodiment.

In addition, while pressing the rotary operation lever 380 of the clamp means 300 to the bottom, to reach the hot air outlet 220a instantaneously close to the hot air range to remove from the immediately after the cover, the exhaust port 120 And to remove the smell and smoke by removing the coating through the exhaust fan 140 is the same as the embodiment.

Only in the step of preparing the cutting process after stripping the coating of the optical fiber, unlike the embodiment does not need to move the clamp means 300 in a linear position. In the present embodiment, since the heater 220, the clamp means 300, and the cutting means 400 are all disposed in a straight line, the cutting operation may be achieved only by the rotation operation of the clamp means 300.

On the other hand, the coated optical fiber 1 is subjected to a cutting process, in which the cutting method is an ultrasonic cutting method, in order to provide a good cutting surface, it is necessary to provide a constant tension to the optical fiber prior to the cutting process.

That is, as shown in FIGS. 7A and 7B, when the cam lever 396 fixedly coupled to the tip of the fixed shaft 260 is rotated from the vertical state to the horizontal state, the cam lever 396 is bilaterally divided by the characteristics of the cam curve 396a. The clamp bundles 310a and 310b are guided to the small-diameter ring bushes 392 and 393 by the elastic force of the elastic member 394 therein, and push the tension-applied pusher 395 outward by a predetermined play. In this case, the clamped optical fiber 1 provides a constant tension to the optical fiber by the left and right pulling force.

Thereafter, the cutting operation is started. First, the ultrasonic oscillator 491 is operated to provide the operating force to the cutter 490, and then the cutting lever 480, which is rotatably coupled to one side of the front end of the body 410, is clamped (300). When turning toward), the interference protrusion 470 on the side of the sliding body 440 which is in an interference state is released by the lever, and in response thereto, the spring 450a of the damper 450 behind the body 440 expands. While the piston (450b) and the piston rod (450c) is gradually advanced by the resistance of the air, the forward force is sliding slidingly coupled to the body 410 by the interference state between the piston rod (450c) and the stopper (430) The cutter 490 at the tip of the ultrasonic oscillator 491 fixed to the upper portion of the body 440 and the sliding body 440 is cut at the same time as the outer peripheral surface of the optical fiber. This completes the one-step work of another embodiment for stripping and cleaning and cutting the optical fiber.
