Technical field

The invention relates to the field of optical fiber cutting, in particular to an optical fiber cutting machine propulsion device, and discloses corresponding clamps and cutting machines.

Background technique

Before installation, the optical fiber is composed of bare fiber and a cladding layer wrapped around the bare fiber (the cladding layer includes the coating on the surface of the bare fiber and the rubber layer outside the coating, which is not limited to a structure). , You need to first strip the cladding of the free end of the fiber, and then cut the exposed bare fiber to form a fiber end face that meets the requirements.

The cutting process is as follows:

Place the covered section next to the exposed bare fiber on a base with a slot, position by the slot, and then buckle the cover plate that can be flipped on the base to clamp the fiber (the clip The holding mechanism is called a clamping positioning device), and then the bare fiber is also placed on another base with a slot, and then the cover plate that can be flipped on the base is buckled to clamp the bare fiber (the two bases There is a gap between them, and a part of the bare fiber is located in this gap and is not covered.) At this time, the uncovered bare fiber is cut by a cutter whose blade is perpendicular to the fiber axis to form a fiber end face that meets the requirements. The free end of the formed new optical fiber can be used for subsequent use.
