Problems solved by technology

At present, there is no special device for pasting this type of fiber grating sensor, which requires manual positioning and pasting. The positioning accuracy is poor, the pasting speed is slow, the efficiency is low, and the pasting quality is poor, which greatly affects the use of unpackaged fiber grating multi-measuring point strain / stress sensors.

Embodiment 1

[0050] This embodiment provides a fiber grating sensor fast positioning paste device, such as figure 1 As shown, it includes: a guide scale 1, a moving glue head 2, a first fixing buckle 3, a second fixing buckle 4, a first support member 5 and a second support member 6;

[0051] The guide scale 1 includes a scale line, which is used to locate the sticking position of the fiber grating sensor;

[0052] The mobile gluing head 2 is movably connected with the guide scale 1, and is used to move along the scale line so that the adhesive material is coated on the sticking position on the fiber grating sensor, so that the fiber grating sensor is pasted to the surface of the measured structure;

[0053] The first fixing buckle 3 and the second fixing buckle 4 are buckled on the two side surfaces of the guide scale 1 respectively, and are used to fix the guide scale 1 to the surface of the structure to be measured;

[0054] The first supporting part 5 and the second supporting part 6 ...

Embodiment 2

[0077] This embodiment provides a fast positioning and pasting method for a fiber grating sensor, which can be applied to the fast positioning and pasting device for a fiber grating sensor in embodiment 1, such as Figure 10 As shown, the method includes the following steps:

[0078] S1. Fix the fast positioning and sticking device of the fiber grating sensor to the surface of the structure under test through the first fixing buckle and the second fixing buckle, so that the mobile glue applicator is placed near the position to be pasted;

[0079] S2. Pull the lifting handles of the first supporting part and the second supporting part, and lift the outer pressing parts of the two;

[0080] S3, pass the fiber grating sensor through the gap between the inner pressing piece and the outer pressing piece respectively, so that the position to be pasted of the fiber grating sensor is aligned with the position to be pasted on the surface of the measured structure;

[0081] S4. Loosen ...

Abstract

The invention discloses a rapid positioning and pasting device and method for a fiber grating sensor, and relates to the technical field of fiber sensor installation. The device comprises a guide scale, a movable gluing head, a first fixing buckle, a second fixing buckle, a first supporting component and a second supporting component, wherein the guide scale comprises scale marks and is used for positioning the pasting position of the fiber grating sensor; the movable gluing head is movably connected with the guide scale and used for moving along the scale marks to enable the pasting positionof the fiber grating sensor to be coated with a gluing material; the first fixing buckle and the second fixing buckle are buckled on the surfaces of the two sides of the guide scale in a sleeving moderespectively and used for fixing the guide scale to the surface of a measured structure; and the first supporting component and the second supporting component are connected to the two ends of the guide scale respectively and used for fixedly supporting the two ends of the fiber grating sensor, so that the fiber grating sensor is straightened in the scale mark direction of the guide scale and tightly attached to the surface of the measured structure. The rapid positioning and pasting device and method have the advantages of being high in pasting speed, high in precision, good in quality, reliable in work and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of optical fiber sensor installation, in particular to a fast positioning and pasting device and method for an optical fiber grating sensor. Background technique [0002] The unpackaged fiber grating multi-measuring point strain / stress sensor has flexible layout and high cost performance, and is widely used in the monitoring of physical quantities such as stress, strain and temperature of engineering structures. Compared with conventional resistive strain gauges, the fiber grating sensor has the advantages of strong anti-electromagnetic interference and long-term stability, especially suitable for long-term monitoring of structural strain. When measuring strain, it is necessary to paste the fiber grating sensor on the structure under test, and the fiber grating sensor is a cylinder with a small diameter (micron scale). When pasting, there is a line contact between the sensor and the structure under test, whi...
