Description
Technical Field
The invention belongs to the technical field of optical fiber cutting equipment, and particularly relates to a large-core-diameter optical fiber cutting device with an eccentric cutter wheel.
Background
The optical fiber is called optical fiber for short, the glass optical fiber is used as a light conduction tool, and the transmission principle is total reflection of light. Bare optical fibers are generally divided into three layers: the core is a high-refractive-index glass core, the middle is a low-refractive-index glass cladding, and the outermost is a resin reinforced coating.
The optical fiber cutter is used for cutting glass optical fibers, and the cut sections of the optical fibers are required to be flat and perpendicular to the axes of the optical fibers, so that the optical fiber cutter is suitable for device packaging, cold welding and hot welding, and the short optical fibers can be spliced into optical fibers with enough length or connected with related photoelectric devices.
The large-core multimode fiber with large numerical aperture can transmit large signals and energy compared with the conventional small-core multimode fiber, and the advantage and other advantages enable the large-core multimode fiber to be more and more widely applied to the fields of communication engineering, sensing devices, energy transmission and the like.
The large-core bare optical fiber (the diameter of the cladding of the optical fiber ranges from 125 mu to 1000 mu or more) is different from the conventional 125 mu and thinner bare optical fiber, and the defect end is obvious when the conventional optical fiber cutter is used for cutting the large-core bare optical fiber: the cutting-off cannot be guaranteed to be really stable, the cutting-off may be broken, extruded or bent, the position deviation of the fracture is large, the tangent plane is uneven, the tangent plane is not perpendicular to the inclination of the optical axis, and even the cutting-off cannot be carried out, so that the operation is inconvenient, time and labor are wasted.
At present, the large core is cut by the optical fiber mainly in two methods.
The first method is a scribing method, in which a straight blade is used to scribe a cleft on the surface of the optical fiber, and then pressure is applied to the cleft from the side opposite to the cleft, so that the cleft of the optical fiber is expanded and broken; the method has high requirement on the precision of a cutting mechanism, and if the split is asymmetric with the cross section of the optical fiber, the cross section is not vertical to the optical axis of the optical fiber easily; the same part on the cutting knife is repeatedly scratched with optical fiber, and is easy to wear and discard.
In the second drawing method, tension is applied to the two ends of the optical fiber to tighten the optical fiber, then a straight blade knife is used to press out a split on the surface of the optical fiber, and the split is continuously deepened by continuous feeding until the optical fiber is broken. The method has high requirements on the precision of the cutter, and the cutter is required to be very sharp, otherwise, the cut section is not smooth, the use cost is high, and the cut depth is not easy to control, so that the quality of the cut section is influenced.
Therefore, it is an urgent need to solve the above problems by those skilled in the art to develop a cutting device capable of efficiently and smoothly cutting a large-core optical fiber.
