Method for stripping optical fiber from intelligent fiber reinforced plastic plate and processing equipment

Technical Field

The invention relates to the technical field of preparation processes of intelligent fiber reinforced plastic plates, in particular to a method for stripping optical fibers from an intelligent fiber reinforced plastic plate and processing equipment.

Background

The fiber grating is a diffraction grating, and the probability of refraction of the fiber core inside the fiber grating is increased by a certain method, so that a passive filter element formed by axial periodic modulation is formed; the intelligent fiber reinforced plastic plate is a fiber reinforced plastic plate containing fiber gratings. In recent years, the intelligent fiber reinforced plastic board can provide more accurate monitoring data for tension stress control and later health monitoring due to the dual functions of reinforcement and monitoring for buildings, and is paid much attention by people in the field of building reinforcement. However, the prior building reinforcing field uses common fiber reinforced plastic plates, the precision requirement in the assembling process is relatively low, and the difficulty is also low; the fiber bragg grating is a product in the communication industry, is a highly precise optical transmission product, is precise and complicated in related use and operation, and has relatively high operation difficulty; the intelligent fiber reinforced plastic plate is a product obtained by comprehensively utilizing the two products, so the difficulty attribute of the preparation step of the intelligent fiber reinforced plastic plate is larger, the problem that after the fiber grating is coupled with the common fiber reinforced plastic plate, part of optical fibers need to be separated for fusion splicing, the diameter of the optical fibers is small, the process difficulty is large, and the application development of the intelligent fiber reinforced plastic plate is seriously limited.

At present, an intelligent fiber reinforced plastic plate is usually prepared by adopting a pultrusion mode, the method has small limit on the size of the plate, and the method is an efficient processing method suitable for producing carbon fiber, glass fiber or other fiber continuous plates.

When the method is adopted to prepare the intelligent fiber reinforced plastic plate, the whole bare fiber grating is embedded into the fiber reinforced plastic plate substrate, and part of the optical fiber with the length of about 20-30 cm is taken out for fusion; however, the optical fiber has a small diameter of about 0.2mm, and has a low strength, is easily damaged, has a transparent or light yellow color, is easily integrated with the color of the fiber reinforced plastic board matrix after being embedded in the fiber reinforced plastic board matrix, is not easily found by naked eyes, is difficult to confirm the position, cannot be observed at the position of the head of the optical fiber in the middle of the fiber reinforced plastic board matrix under normal conditions, and is easily broken when being taken out, thereby causing peeling failure.

In addition, the requirement for operation technique is particularly high when taking out, specifically, in the prior art, a rubber sleeve is adopted to wrap a part of the end of the optical fiber, the whole optical fiber grating is embedded into the fiber reinforced plastic plate substrate, one end of the optical fiber protected by the rubber sleeve is taken out after molding, and the end of the optical fiber protected by the rubber sleeve is utilized for welding; the whole taking-out step mainly depends on careful and careful polishing, and the fiber reinforced plastic board substrate at the edge of the rubber sheath is removed little by little, and the optical fiber is ensured not to be damaged, but the taking-out method has long time consumption, low qualification rate and very low production efficiency; moreover, after the optical fiber is embedded into the fiber reinforced plastic plate substrate, the optical fiber is easy to be entangled with the fiber to be bent, so that the optical fiber is easily damaged due to inaccurate positioning in the stripping process of the optical fiber; in the prior art, some technical schemes are to apply a self-lubricating coating on the surface of an optical fiber to be taken out, then transverse cutting and longitudinal cutting are performed firstly, and finally a wire stripper is used for stripping the wire, and the taking-out method also has the problems.

In summary, in the prior art, there are problems of difficult accurate positioning, easy damage of the optical fiber, low success rate in stripping, high rejection rate and low stripping efficiency when stripping the optical fiber from the intelligent fiber reinforced plastic plate.
