Auxiliary device for pasting fiber grating

Abstract

The invention discloses an auxiliary device for FBG (Fiber Bragg Grating) pasting, and the device comprises an FBG guide rack, a pretightening force display, a pretightening force sensor, a guide rack left branch clamping mechanism, a guide rack right branch clamping mechanism, a pretightening force spiral loading mechanism, and a glue layer length and thickness control mechanism. The FBG guide rack forms an annular integrated structure through a guide rack left branch and a guide rack right branch. The guide rack left branch is provided with an FBG guide groove, and the outer side of the guide rack right branch is uniformly provided with a guide rack right branch FBG guide wheel. The guide rack left branch clamping mechanism is disposed on the guide rack left branch, and the guide rack right branch clamping mechanism is disposed on the guide rack right branch. The pretightening force sensor is disposed between the guide rack right branch clamping mechanism and the pretightening force spiral loading mechanism. The device facilitates the pasting of an FBG, and achieves accurate applying of a pretightening force and the control of the length and thickness of the FBG gluing layer. The guide rack right branch and the guide rack left branch are designed to be shaped like an arc, thereby reducing the size of the device and achieving a guide effect.

Description

technical field [0001] The invention relates to a pasting device, in particular to an auxiliary device for fiber grating pasting. Background technique [0002] Most of the existing fiber grating pasting methods adopt manual direct pasting method, and a certain pre-tightening force needs to be applied in the process of pasting the fiber grating. Control, such a manual direct pasting method, first of all, the loaded pre-tightening force cannot be accurately controlled, and the shaking of the weight during the loading process can easily break the FBG; It has a great impact. Manual direct pasting cannot accurately guarantee the length and thickness of the fiber grating pasting adhesive layer, so that the pasting effect of the fiber grating cannot be guaranteed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a compact, simple and convenient auxiliary device for pasting fiber gratings to facilitate the pasting of fib...
