Abstract
A coating removal tool removes a resin coating positioned at a distal end portion of a coated optical fiber. The coating removal tool includes a first holding part holding the resin coating positioned at the distal end portion, a second holding part configured to hold a base end portion of the coated optical fiber adjacent to the distal end portion, and a pedestal part configured to support the first holding part and the second holding part. The first holding part includes a heater for heating the resin coating positioned at the distal end portion and a blade for making a notch in the resin coating, and is provided to be slidable relative to the pedestal part. The second holding part is fixed relative to the pedestal part.
Claims6
A coating removal tool that removes a first resin coating at a first distal end of a first coated optical fiber and a second resin coating at a second distal end of a second coated optical fiber, the first coated optical fiber including a first glass fiber and the first resin coating that covers an outer circumference of the first glass fiber and the second coated optical fiber including a second glass fiber and the second resin coating that covers an outer circumference of the second glass fiber, the coating removal tool comprising:
- a first holder that is configured to hold the first distal end of the first coated optical fiber extending from a first side in a predetermined direction, or hold the second distal end of the second coated optical fiber extending from a second side in the predetermined direction;
- a second holder that is adjacent to the first holder on the first side and configured to hold a first base end of the first coated optical fiber;
- a third holder that is adjacent to the first holder on the second side and configured to hold a second base end of the second coated optical fiber;
- and
- a pedestal configured to support the first holder, the second holder and the third holder, wherein
- the first holder includes:
- a heater that is configured to heat the first distal end of the first coated optical fiber and the second distal end of the second coated optical fiber,
- a first blade that is configured to make a notch in a portion of the first resin coating at a boundary between the first distal end and the first base end of the first coated optical fiber, and
- a second blade that is configured to make a notch in a portion of the second resin coating at a boundary between the second distal end and the second base end of the second coated optical fiber,
- the first holder is configured to be slidable along the predetermined direction relative to the pedestal,
- the second holder and the third holder are fixed relative to the pedestal,
- the second holder includes a first switch that detects a presence or an absence of the first coated optical fiber,
- the third holder includes a second switch that detects a presence or an absence of the second coated optical fiber, and
- the coating removal tool further comprises:
- a first sensor that is configured to detect whether the first holder is within a predetermined distance from the second holder, and
- a second sensor that is configured to detect whether the first holder is within a predetermined distance from the third holder.
