Description

Technical Field

[0001] The invention relates to the technical field of preparation technology of intelligent fiber reinforced plastic plates, and in particular to a method for stripping optical fibers from intelligent fiber reinforced plastic plates and processing equipment. Background Art

[0002] Fiber Bragg grating is a diffraction grating. It mainly uses a certain method to increase the probability of refraction of the optical fiber core inside it, thereby forming a passive filtering element with axial periodic modulation; smart fiber reinforced plastic plate is a fiber reinforced plastic plate containing fiber Bragg grating. In recent years, smart fiber reinforced plastic plate has attracted much attention in the field of building reinforcement because it can provide dual functions of reinforcement and monitoring for buildings, and can provide more accurate monitoring data for tension stress control and later health monitoring. However, ordinary fiber reinforced plastic plates are used in the existing building reinforcement field, and the assembly process requires relatively low precision and is less difficult; while fiber Bragg grating is a product of the communication industry and is a highly precise optical transmission product. The related use operations are precise and complicated, and the operation is relatively difficult; smart fiber reinforced plastic plate is the product obtained by the comprehensive application of these two products. Therefore, the preparation steps of smart fiber reinforced plastic plate are relatively difficult, mainly reflected in the need to separate part of the optical fiber for fusion after the fiber Bragg grating is coupled with the ordinary fiber reinforced plastic plate, and the optical fiber has a thin diameter, resulting in a high process difficulty, which seriously limits the application and development of smart fiber reinforced plastic plate.

[0003] At present, pultrusion is often used to prepare smart fiber reinforced plastic boards. This method has little restriction on the size of the board and is an efficient processing method suitable for the production of carbon fiber, glass fiber or other fiber continuous boards.

[0004] When this method is used to prepare an intelligent fiber reinforced plastic plate, the entire bare fiber grating needs to be buried in the fiber reinforced plastic plate matrix, and a portion of the optical fiber of about 20 to 30 cm is taken out for fusion splicing; however, the optical fiber has a thin diameter of about 0.2 mm, and its strength is low, it is easily damaged, and its color is transparent or light yellow. After being buried in the fiber reinforced plastic plate matrix, it is easy to blend with the color of the fiber reinforced plastic plate matrix itself, and it is not easy to be found by the naked eye, and it is difficult to confirm the position. Under normal circumstances, the position of the optical fiber head in the middle of the fiber reinforced plastic plate matrix cannot be observed. When taking it out, the optical fiber is very likely to break, resulting in stripping failure.

[0005] In addition, the requirements for the operation technique when taking it out are also particularly high. Specifically, in the existing technical solution, a rubber sleeve is used to wrap a part of the optical fiber head end, and the optical fiber grating is completely buried in the fiber reinforced plastic plate matrix. After molding, the end of the optical fiber protected by the rubber sleeve is taken out, and the end of the optical fiber protected by the rubber sleeve is fused; wherein, the method of taking out the end of the optical fiber protected by the rubber sleeve is usually to cut and grind off the fiber reinforced plastic plate matrix around the optical fiber segment protected by the rubber sleeve little by little. The whole process of taking out mainly relies on careful grinding and removing the edge of the rubber protective sleeve little by little. The fiber reinforced plastic plate matrix with an edge and the optical fiber is not damaged, but this removal method takes a long time, has a low pass rate, and has very low production efficiency; and, since the optical fiber is easily entangled with the fiber and bent after being buried in the fiber reinforced plastic plate matrix, it is easy to cause damage to the optical fiber due to inaccurate positioning during the optical fiber stripping process; in the existing technical solutions, some technical solutions use a self-lubricating coating to apply to the surface of the optical fiber to be removed, and then cut it crosswise and longitudinally, and finally use a wire stripper to strip the wire. This removal method will also cause the aforementioned problems.

[0006] In summary, in the prior art, when stripping optical fibers from smart fiber reinforced plastic plates, there are problems such as difficulty in accurate positioning, easy damage to the optical fibers, low success rate during stripping, high scrap rate, and low stripping efficiency. Summary of the invention

[0007] The purpose of the present invention is to provide a method and processing equipment for stripping optical fibers from smart fiber reinforced plastic plates, so as to alleviate the problems in the prior art of preparing smart fiber reinforced plastic plates, such as difficulty in accurate positioning, easy damage to the optical fibers, low success rate during stripping, high scrap rate and low stripping efficiency when stripping optical fibers from smart fiber reinforced plastic plates.

[0008] To achieve the above objectives, the embodiments of the present invention adopt the following technical solutions:

[0009] In a first aspect, an embodiment of the present invention provides a method for stripping an optical fiber from an intelligent fiber reinforced plastic plate, wherein: the intelligent fiber reinforced plastic plate comprises a fiber reinforced plastic plate substrate, an optical fiber, an optical fiber extraction line and a positioning plate, one end of the optical fiber extraction line is parallel to and close to one end of the optical fiber, and one end of the optical fiber extraction line away from the optical fiber is fixedly connected to one end of the positioning plate in the length direction, the fiber reinforced plastic plate substrate comprises an upper fiber reinforced plastic plate and a lower fiber reinforced plastic plate, along the length direction of the fiber reinforced plastic plate substrate, the optical fiber, the optical fiber extraction line and the positioning plate are buried between the upper fiber reinforced plastic plate and the lower fiber reinforced plastic plate, and the thickness of the fiber reinforced plastic plate substrate at the positioning plate is greater than the thickness of other areas of the fiber reinforced plastic plate substrate except the positioning plate;

[0010] The method for stripping optical fiber from a smart fiber reinforced plastic plate comprises:

[0011] The fiber reinforced plastic plate substrate is clamped by a positioning piece finder having a slit, and the positioning piece finder is slid along the length direction of the fiber reinforced plastic plate substrate to determine the position of the positioning piece on the fiber reinforced plastic plate substrate, and the end mark and the tail mark of the positioning piece are respectively made at the positions on the fiber reinforced plastic plate substrate corresponding to the two ends of the positioning piece in the length direction;

[0012] Cutting the fiber reinforced plastic plate substrate along the end mark to cut off an excess end of the fiber reinforced plastic plate substrate;

[0013] Longitudinal cutting: using a cutting tool assembly, cutting the fiber reinforced plastic plate substrate along both sides of the positioning piece in the length direction, from one of the end mark and the tail mark toward the other of the end mark and the tail mark;

[0014] Separating the positioning sheet: using a stripping tool assembly to separate the positioning sheet from the upper fiber reinforced plastic plate and the lower fiber reinforced plastic plate;

[0015] Cutting off the separated upper fiber reinforced plastic plate and lower fiber reinforced plastic plate at the portion corresponding to the positioning piece;

[0016] Cutting off the redundant fiber reinforced plastic plates at both sides of the fiber reinforced plastic plate substrate in the length direction;

[0017] From the end cross section of the positioning piece, find the optical fiber extraction line and the optical fiber, first take out the optical fiber extraction line, and then use the optical fiber extraction line to pull out the optical fiber, and finally, remove the excess positioning piece inside the fiber reinforced plastic plate matrix and remove the optical fiber extraction line to complete the stripping of the head end of the optical fiber from the smart fiber reinforced plastic plate.

[0018] The method for stripping optical fibers from a smart fiber reinforced plastic plate provided in this embodiment can achieve at least the following beneficial effects in operation:

[0019] (1) It is possible to standardize the stripping steps and significantly improve the success rate of optical fiber stripping. According to nearly 100 stripping process statistical data, when the stripping method is not used in combination with a positioning sheet, the success rate of optical fiber stripping is 60-70%. However, when the stripping method provided by this embodiment is used, the success rate of optical fiber stripping can be increased to 95-99.9%.

[0020] (2) Reduce the difficulty of peeling and positioning. By using a positioning piece finder with a slit to clamp the fiber reinforced plastic plate substrate, the positioning piece finder is slid along the length direction of the fiber reinforced plastic plate substrate to determine the position of the positioning piece on the fiber reinforced plastic plate substrate, which effectively improves the positioning accuracy and avoids the influence of positioning inaccurately caused by residual positioning pieces or application of lubricating coating on mechanical properties;

[0021] (3) The loss rate of the optical fiber is significantly reduced. When the positioning plate is combined without using the stripping method, the probability of optical fiber damage is 10-20%. However, when the above-mentioned method provided by this embodiment is used, the risk of optical fiber damage can be avoided and the probability of damage can be reduced to less than 5%.

[0022] In summary, the present embodiment can effectively improve the success rate of optical fiber stripping, reduce the possibility of optical fiber breakage and the scrap rate, and alleviate the problems in the prior art of preparing smart fiber reinforced plastic plates, such as difficulty in accurate positioning, easy damage to the optical fiber, low success rate during stripping, high scrap rate, and low stripping efficiency when stripping the optical fiber from the smart fiber reinforced plastic plate.

[0062] Embodiment 1

[0063] This embodiment provides a method for stripping optical fibers from a smart fiber reinforced plastic plate. Figures 1 to 8 The intelligent fiber reinforced plastic plate 100 corresponding to the method includes a fiber reinforced plastic plate substrate 1, an optical fiber 2, an optical fiber extraction line 3 and a positioning plate 4, one end of the optical fiber extraction line 3 is parallel to and close to one end of the optical fiber 2, and the end of the optical fiber extraction line 3 away from the optical fiber 2 is fixedly connected to one end of the positioning plate 4 in the length direction. The fiber reinforced plastic plate substrate 1 includes an upper fiber reinforced plastic plate 11 and a lower fiber reinforced plastic plate 12. Along the length direction of the fiber reinforced plastic plate substrate 1, the optical fiber 2, the optical fiber extraction line 3 and the positioning plate 4 are buried between the upper fiber reinforced plastic plate 11 and the lower fiber reinforced plastic plate 12, and the thickness of the fiber reinforced plastic plate substrate 1 at the positioning plate 4 is greater than the thickness of other areas of the fiber reinforced plastic plate substrate 1 except the positioning plate 4.

[0064] The method for stripping optical fibers from a smart fiber reinforced plastic plate provided in this embodiment includes:

[0065] Use Figure 1 The positioning piece finder 5 with a clamping gap shown in the figure clamps the fiber reinforced plastic plate substrate 1, as shown in the figure Figure 2 As shown, the positioning piece finder 5 is slid along the length direction of the fiber reinforced plastic plate substrate 1 to determine the position of the positioning piece 4 on the fiber reinforced plastic plate substrate 1, and as shown in FIG. Figure 3 As shown, the end mark 41 and the tail mark 42 of the positioning piece 4 are respectively made at the positions corresponding to the two ends of the positioning piece 4 in the length direction on the fiber reinforced plastic plate substrate 1. The end mark 41 and the tail mark 42 can be, but are not limited to, a marking point or a marking point. Figure 3 and Figure 4 The marking line perpendicular to the length direction of the positioning piece 4 shown in the figure, or another marking structure such as pasting a marker or another marking structure; wherein, the gap width of the positioning piece finder 5 is controlled according to the thickness of the fiber reinforced plastic plate substrate 1, and its width is set to be smaller than the thickness of the positioning piece 4 on the fiber reinforced plastic plate substrate 1 and about 0.01~0.09mm larger than the thickness of the area other than the positioning piece 4 on the fiber reinforced plastic plate substrate 1. The positioning piece finder 5 moves from one end to the other end on the fiber reinforced plastic plate substrate 1. When it moves to the positioning piece 4, the positioning piece finder 5 will be stuck by the positioning piece 4 because of the obvious change in thickness. At the place where it just got stuck, mark the end mark 41 and the tail mark 42 of the positioning piece 4 on the fiber reinforced plastic plate substrate 1 along the edge of the positioning piece finder 5.

[0066] like Figure 4 As shown, the fiber reinforced plastic plate substrate 1 is cut along the end mark 41, and the redundant end of the fiber reinforced plastic plate substrate 1 is cut off. The redundant fiber reinforced plastic plate 1001 can be Figure 4 Obtain; in this step, cutting off the excess fiber reinforced plastic plate 1001 can assist in positioning through the location of the positioning piece 4, avoiding the problem of over-cutting causing damage to the optical fiber and under-cutting causing difficulty in stripping;

[0067] like Figure 5 As shown, longitudinal cutting: using the cutting tool assembly 9, the fiber reinforced plastic plate substrate 1 is cut along both sides of the length direction of the positioning piece 4, from one of the end mark 41 and the tail mark 42 toward the other of the end mark 41 and the tail mark 42. The length direction of the positioning piece 4 is the "longitudinal direction" in this step. Preferably, the fiber reinforced plastic plate substrate 1 is cut from the end mark 41 to the tail mark 42;

[0068] like Figure 6As shown, the positioning sheet 4 is separated: the positioning sheet 4 is separated from the upper fiber reinforced plastic plate 11 and the lower fiber reinforced plastic plate 12 by using the stripping tool assembly 10;

[0069] Cutting off and separating the upper fiber reinforced plastic plate 11 and the lower fiber reinforced plastic plate 12 at the portion corresponding to the positioning plate 4;

[0070] The redundant fiber reinforced plastic plates 1001 on both sides of the fiber reinforced plastic plate substrate 1 in the length direction are cut off, and the removed redundant fiber reinforced plastic plates 1001 can be replaced by Figure 5 get;

[0071] like Figure 7 and Figure 8 As shown, the steps of removing the positioning piece 4 and the optical fiber extraction line 3 specifically include: finding the optical fiber extraction line 3 and the optical fiber 2 from the end cross section of the positioning piece 4, first taking out the optical fiber extraction line 3, and then using the optical fiber extraction line 3 to pull out the optical fiber 2; this step can specifically but not limited to, tearing a tear 40 at the end cross section of the positioning piece 4, lifting part of the optical fiber extraction line 3 from the tear 40, pinching the positioning piece 4 at the tear 40, and then lifting all the optical fiber extraction line 3, and then taking the optical fiber 2 out of the tear 40, and pulling out the positioning piece 4 and the optical fiber extraction line 3 along the length direction of the fiber reinforced plastic plate substrate 1; finally, removing the excess positioning piece 4 inside the fiber reinforced plastic plate substrate 1 and removing the optical fiber extraction line 3, and completing the stripping of the optical fiber head end from the smart fiber reinforced plastic plate.

[0072] The method for stripping optical fibers from a smart fiber reinforced plastic plate provided in this embodiment can achieve at least the following beneficial effects in operation:

[0073] (1) It is possible to standardize the stripping steps and significantly improve the success rate of optical fiber stripping. According to nearly 100 stripping process statistical data, when the positioning sheet 4 is combined without using the stripping method, the success rate of optical fiber stripping is 60-70%. When the stripping method provided by this embodiment is used, the success rate of optical fiber stripping can be increased to 95-99.9%.

[0074] (2) To reduce the difficulty of peeling and positioning, the fiber reinforced plastic plate substrate 1 is clamped by using a positioning piece finder 5 with a clamping gap, such as Figure 2 As shown, the positioning piece finder 5 is slid along the length direction of the fiber reinforced plastic plate substrate 1 to determine the position of the positioning piece 4 on the fiber reinforced plastic plate substrate 1, which effectively improves the positioning accuracy and avoids the influence of inaccurate positioning caused by the residual positioning piece 4 or the application of lubricating coating on the mechanical properties;

[0075] (3) The loss rate of the optical fiber is significantly reduced. When the positioning piece 4 is combined without using the stripping method, the probability of optical fiber damage is 10-20%. However, when the above-mentioned method provided by this embodiment is used, the risk of optical fiber damage can be avoided and the probability of damage can be reduced to less than 5%.

[0076] In summary, the present embodiment can effectively improve the success rate of optical fiber stripping, reduce the possibility of optical fiber breakage and the scrap rate, and alleviate the problems in the prior art of preparing smart fiber reinforced plastic plates, such as difficulty in accurate positioning, easy damage to the optical fiber, low success rate during stripping, high scrap rate, and low stripping efficiency when stripping the optical fiber from the smart fiber reinforced plastic plate.
