Technical Field

In the coating process, the alignment of the production line is poor, so that the concentricity deviation of the cladding coating of the optical fiber is easy to cause, and the performance of the optical fiber is influenced. At present, measures for controlling concentricity errors of a coating layer in the wire drawing process mainly comprise the following steps: the concentricity of the coating in the wire drawing process is ensured by mechanically calibrating the center of the wire drawing tower and the center of the horizontal die holder.

The on-line adjusting device and the on-line monitoring and adjusting device for the coating concentricity of the optical fiber provided by the embodiment of the invention are further described below with reference to the embodiment and the attached drawings.
Example 1
Fig. 1 is a schematic structural diagram of an on-line device for adjusting the concentricity of optical fiber coating according to an embodiment of the present invention. Fig. 2 is a schematic diagram of an arrangement structure of a piezoelectric ceramic component in an on-line adjusting device for coating concentricity of an optical fiber according to an embodiment of the present invention. As shown in fig. 1, an on-line adjusting device for coating concentricity of an optical fiber according to an embodiment of the present invention includes: a piezoelectric ceramic component 3 and a booster 4 connected to the piezoelectric ceramic component.
Specifically, the piezoelectric ceramic assembly 3 includes a first piezoelectric ceramic member 31 provided on the cup base 2 in the Z-axis direction, a second piezoelectric ceramic member 32 provided on the outer periphery of the cup 1 in the X-axis direction, and a third piezoelectric ceramic member 33 provided on the outer periphery of the cup 1 in the Y-axis direction. The number of the first piezoelectric ceramic pieces 31 is at least 2, and the number of the second piezoelectric ceramic pieces 32 and the third piezoelectric ceramic pieces 33 is at least 1.
The purpose of the three groups of piezoelectric ceramic components 31, 32 and 33 is to control and adjust each piezoelectric ceramic component to change the dimension (such as the length, the width or the height) of each piezoelectric ceramic component, thereby achieving the purpose of adjusting the angle or the position of the coating cup and finally realizing the adjustment of the concentricity of the coating of the optical fiber. Based on this working principle, the following arrangement is preferably adopted: as shown in fig. 2, the number of the first piezoceramic elements 31 is 4, and the first piezoceramic elements are respectively and uniformly arranged on the coating cup base 2 relative to the center of the coating cup base 2 and are used for adjusting the height or the horizontal inclination angle of the coating cup; the number of the second piezoelectric ceramic pieces 32 is 2, and the second piezoelectric ceramic pieces are respectively arranged at two sides of the coating cup 1 in a close fitting manner along the X-axis direction and are used for adjusting the displacement of the coating cup 1 along the X-axis direction; the third piezoceramic elements 33 are 2 in number, and are respectively arranged on both sides of the coating cup 1 in a close fitting manner along the Y-axis direction for adjusting the displacement of the coating cup 1 in the Y-axis direction. The arrangement of the piezoceramic assemblies 3 in a close fitting manner makes it easier to force the coating cup and the adjustment reaction more sensitive when the position of the coating cup is adjusted by the piezoceramic assemblies 31, 32, 33, even a small position adjustment is achieved.
It is also preferable that the piezoelectric ceramic component is provided in the following manner: the number of the first piezoelectric ceramic pieces 31 is 4, and the first piezoelectric ceramic pieces are uniformly fixed on the coating cup base 2 relative to the center of the coating cup base 2; the number of the second piezoelectric ceramic pieces 32 is 1, and the second piezoelectric ceramic pieces are fixedly arranged on one side of the coating cup 1 along the X-axis direction; the number of the third piezoelectric ceramic pieces 33 is 1, and the third piezoelectric ceramic pieces are fixedly arranged on one side of the coating cup 1 along the Y-axis direction. The piezoelectric ceramic pieces 31, 32 and 33 are respectively fixedly arranged on the coating cup 1 or the coating cup base 2, and the angle or the position of the coating cup can be adjusted under the driving action of the piezoelectric ceramic pieces only by arranging the piezoelectric ceramic pieces on one side, so that the good adjustment of the coating cup can be still realized under the conditions of simplifying the number of parts and saving the cost.
Since the pressing force or pulling force of the piezoelectric ceramic component alone is sometimes insufficient to move the position of the coating cup 1 or the coating cup base 2 when the coating cup 1 or the coating cup base 2 is regulated by the piezoelectric ceramic component 3, the booster 4 needs to be arranged on the basis of the piezoelectric ceramic component 3, and the booster 4 can be any booster component or force-applying device which can perform the functions, such as a gravity component, and the like, and the booster 4 is preferably used as a two-dimensional regulation platform. And in order to be able to control and regulate the piezo-ceramic component 3 and the booster 4 more conveniently, the piezo-ceramic component 3 and the booster 4 can be connected to a control master 5.
Preferably, the first piezoelectric ceramic member 31, the second piezoelectric ceramic member 32 and the third piezoelectric ceramic member 33 each employ stacked piezoelectric ceramic plates more efficiently than employing monolithic piezoelectric ceramic plates.
Preferably, the maximum variation displacement of the first piezoelectric ceramic piece 31, the second piezoelectric ceramic piece 32 and the third piezoelectric ceramic piece 33 is not less than 0.2mm, the working voltage is 100-200V, and the higher-precision adjustment of the coating cup can be realized, so that the purpose of effectively adjusting the coating concentricity of the optical fiber is achieved.
In summary, according to the optical fiber coating concentricity online adjusting device provided by the embodiment of the invention, the position of the coating cup or the coating cup base is adjusted by controlling and adjusting the piezoelectric ceramic component, so that the coating cup is kept at the expected required position, and therefore, the optical fiber is ensured to have good concentricity when being coated by the coating cup.

Since the first embodiment has already been described in detail for the online adjustment device, the details are not repeated here.
As shown in fig. 4, the on-line monitoring device 6 includes: the laser device 61, the photoelectric detection device 62 and the programmable logic controller 7, the laser device 61 sets up around optic fibre, on the horizontal plane perpendicular to optic fibre central axis, and the photoelectric detection device 62 sets up with the laser device 61 correspondence so that the laser signal that the photoelectric detection device 62 sent of laser device 61, and the photoelectric detection device 62 is connected with the programmable logic controller 7, and piezoceramics subassembly 3 and helping hand piece 4 are connected with the programmable logic controller 7. The working principle of the on-line monitoring device 6 is as follows: the laser beam emitted by the laser device 61 passes through the optical fiber, the multi-beam interference and diffraction phenomena occur in the optical fiber, then the photoelectric detection device 62 detects the multi-level interference related diffraction composite stripe signals after the laser beam irradiates the optical fiber, and then the symmetry of the stripes is judged according to a preset program, when the symmetry of the stripes exceeds a certain proportion or all the stripes is good, the coating concentricity of the optical fiber is good, otherwise, the coating concentricity of the optical fiber is poor. It should be noted that, the preset program and the judgment rule may be preset by the programmable logic controller 7 or the control host, and the setting manner and the specific content may be determined according to the actual situation, which is not limited by the embodiment of the present invention.

The arrangement mode can determine whether the concentricity of the optical fiber coating meets the requirement by judging the symmetry of interference fringes obtained by irradiating the optical fiber with laser beams in the X-axis direction and the Y-axis direction, and the operation and the detection are easier because only two interference fringes in the X-axis direction and the Y-axis direction exist.
