Description

Technical Field

[0001] The utility model relates to the technical field of packaging jigs, in particular to a jig used for optical fiber grating packaging. Background Art

[0002] Fiber Bragg grating (FBG) is a new type of optical passive device that changes or controls the propagation behavior and mode of light in the area by establishing a periodic refractive index distribution in the axial direction of the optical fiber. Fiber Bragg grating (FBG) has been widely used in the field of optical sensing in recent years due to its many advantages such as simple production, good stability, small size, anti-electromagnetic interference, flexible use, easy integration with optical fiber and the ability to form a network. According to the different usage scenarios and different functions of fiber Bragg grating, there are different packaging methods and external field application methods. Common fiber Bragg grating packaging methods include embedding the fiber Bragg grating in two different substrate materials in segments and embedding the fiber Bragg grating in the same substrate material. The existing common fixture for fiber Bragg grating packaging is the overall packaging of the fiber Bragg grating, which cannot meet different packaging methods. Therefore, we propose a new type of fixture for fiber Bragg grating packaging. Utility Model Content

[0003] According to the above existing technical problems, the utility model provides a jig for fiber grating packaging, which is characterized by comprising a cabinet, a support frame, a top plate, a hydraulic cylinder, an upper mounting plate, an upper mold, a connecting block, a lower mounting plate, and a lower mold. The cabinet is connected to a plurality of support frames, a top plate is connected between the support frames, the top plate is connected to a hydraulic cylinder, the hydraulic cylinder is connected to an upper mounting plate, an upper mold is installed on the upper mounting plate, a connecting block is connected to the cabinet, the connecting block is connected to a lower mounting plate, and the lower mounting plate is connected to a lower mold;

[0004] The upper mounting plate and the lower mounting plate are provided with a plurality of mounting holes B;

[0005] The upper mold and the lower mold are provided with a plurality of mounting holes A;

[0006] The size of the connecting block is smaller than that of the lower mounting plate.

[0007] Beneficial effects of the utility model:

[0008] The utility model can install the upper mold and the lower mold on the upper mounting plate and the lower mounting plate respectively, and the hydraulic cylinder is turned on to press the upper mounting plate and the upper mold down, thereby encapsulating the fiber grating. Among them, the upper mold and the lower mold can be a whole piece of the same base material, or two or more pieces of different models or different types of base materials. In addition, the setting of the support frame will not block the placement of the longer fiber grating, and can also reduce the deadweight of the fixture. The setting of the upper mounting plate and the lower mounting plate facilitates the replacement of different upper molds and lower molds. BRIEF DESCRIPTION OF THE DRAWINGS
