The invention discloses a jig and carrier plate used for attaching circuit board strength reinforcing pieces. The jig used for attaching the circuit board strength reinforcing pieces is characterized by comprising a bottom plate and a cover plate. The bottom plate is provided with an upper surface used for supporting a circuit board. The cover plate is matched with the bottom plate and used for clamping the circuit board placed on the upper surface. The cover plate is provided with at least one first through hole. The first through holes make the circuit board be exposed partially. According to the jig used for attaching the circuit board strength reinforcing pieces, the bottom plate is adopted for supporting the circuit board, the circuit board is covered by the cover plate, and a region, to be reinforced, of the circuit board is exposed through the first through hole in the cover plate, and then the strength reinforcing pieces are embedded into the first through holes to be attached to the circuit board. Due to the fact that the cover plate has a certain thickness, an operator can accurately embed the strength reinforcing pieces into the first through holes and pasting the strength reinforcing pieces to be region to be reinforced, pasting precision is greatly improved, meanwhile, time for alignment through the naked eyes is shortened, and working efficiency is improved.

The invention discloses a fiber grating sensor fast positioning and pasting device and method, and relates to the technical field of fiber optic sensor installation. The ruler is movable and connected, and is used to move along the scale line so that the viscose material is coated on the sticking position on the fiber grating sensor; the first fixed buckle and the second fixed buckle are buckled on the two sides of the guide scale respectively, and are used to The guide scale is fixed on the surface of the structure to be measured; and the first supporting part and the second supporting part are respectively connected to the two ends of the guide scale, and are used to fix the two ends of the fiber grating sensor, so that the fiber grating sensor moves along the guide scale. The direction of the scale line is arranged straight and close to the surface of the structure under test. The invention has the advantages of fast pasting speed, high precision and good quality, reliable work and convenient operation.

The invention discloses a strain gage pasting device which is used for pasting a strain gage to a to-be-pasted area. The strain gage pasting device comprises a positioning plate, a compression mechanism and a sucking disc assembly, wherein a strain gage positioning groove and a strain gage line guiding groove are formed in the front end of the positioning plate, and a through hole is formed in the positioning plate and communicated with the strain gage positioning groove; the compression mechanism comprises a pressing plate, a pressing block and a guide column, the guide column is connected to the back end of the positioning plate, the pressing plate is connected to the guide column in a sliding manner, the pressing block is connected to the through hole in a sliding manner, and the back end of the pressing block is connected with the pressing plate; the back end of the pressing block does not exceed the strain gage positioning groove, and a containing hole is formed inside the pressing block; and the sucking disc assembly comprises a vacuum sucking disc, a connecting pipe and a connecting joint, the vacuum sucking disc is fixed to the front end of the containing hole, the connecting joint is fixed to the back end of the containing hole, and a connecting pipe is used for connecting the vacuum sucking disc with the connecting joint and located in the containing hole. By means of the pasting device, the strain gage can be sucked to be accurately pasted into the to-be-pasted area.
