Abstract

A coating removal device removing a coating of an optical fiber along an axial direction of the optical fiber includes a heating portion including a cutting blade making a cut in the coating of the optical fiber, and a heater heating a part of the coating that is closer to a tip thereof than the cutting blade; a main body portion including a control board electrically connected with the heater; a holding portion holding the optical fiber, the holding portion being provided on the opposite side to the heater with the cutting blade being located between the holding portion and the heater; and a slide mechanism allowing the holding portion to slidably move with respect to the heating portion such that the holding portion is distanced away from the heating portion in the axial direction. The main body portion, the heating portion and the holding portion are located in this order in the axial direction, and the heating portion includes a vibration notification portion giving information to an operator by vibrating.

First claim

What is claimed is:

1. A coating removal device for removing a coating of an optical fiber along an axial direction of the optical fiber, the coating removal device comprising:
a heating portion including a cutting blade making a cut in the coating of the optical fiber, and a heater heating a part of the coating that is closer to a tip thereof than the cutting blade;
a main body portion including a control board electrically connected with the heater;
a holding portion holding the optical fiber, the holding portion being provided on an opposite side opposite to the heater with the cutting blade being located between the holding portion and the heater;
a slide mechanism allowing the holding portion to slidably move with respect to the heating portion such that the holding portion is distanced away from the heating portion in the axial direction; and
an assisting mechanism providing the holding portion with a first urging force acting in the axial direction to assist a sliding movement of the holding portion in a state where the holding portion is holding the optical fiber,
wherein:
the main body portion, the heating portion and the holding portion are located in this order in the axial direction,
the assisting mechanism includes a restriction member using a second urging force acting in a predetermined direction to restrict provision of the first urging force to the holding portion in a state where the holding portion is not holding the optical fiber,
the heating portion includes a vibration notification portion giving information to an operator by vibrating, and
the vibration notification portion vibrates in a direction generally perpendicular to the predetermined direction.

2. The coating removal device according to claim 1 , wherein the vibration notification portion is located close to the cutting blade of the heating portion.

3. The coating removal device according to claim 2 , wherein:
the heating portion includes a metal base plate secured to a housing of the heating portion, and
the vibration notification portion is secured to the metal base plate.

4. The coating removal device according to claim 3 , wherein:
the slide mechanism includes a slide shaft having an end secured to the holding portion, and
the metal base plate slidably supports the slide shaft.

5. The coating removal device according to claim 1 , wherein:
the heating portion includes a metal base plate secured to a housing of the heating portion, and
the vibration notification portion is secured to the metal base plate.

6. The coating removal device according to claim 5 , wherein:
the slide mechanism includes a slide shaft having an end secured to the holding portion, and
the metal base plate slidably supports the slide shaft.

7. The coating removal device according to claim 1 , wherein:
the main body portion includes a control portion controlling an operation of each of the heater and the vibration notification portion, and
the control portion vibrates the vibration notification portion when the heating of the coating is completed.

8. The coating removal device according to claim 1 , wherein the heating portion includes a screw hole usable to secure the coating removal device at a predetermined installment position in a work line.

9. The coating removal device according to claim 1 , further comprising a buzzer portion giving information to the operator by outputting a sound.

10. The coating removal device according to claim 1 , wherein:
the cutting blade includes two blades making a cut while holding the coating therebetween, and
the heating portion includes a gap adjustment portion changing a size of a gap between the two blades by pivoting.

11. The coating removal device according to claim 1 , further comprising an illumination portion illuminating the holding portion and the heating portion.
