An automatic manufacturing device for complex sensitive elements based on carbon fiber

Abstract

The invention discloses an automated manufacturing apparatus for a complex sensitive element based on carbon fibers. The automated manufacturing apparatus includes: a work bench; a lifting and a translational module disposed on the work bench; a horizontal moving bench installed on the work bench horizontally and movably, wherein a pallet plate for placing wires are arranged on the top of the horizontal moving bench; a wire storage module; a wire placing module installed on a power output end of the lifting and a translational module and used for placing fiber wires coming from the wire storage module on the pallet plate; a pre-impregnation module disposed on a fiber wire path between the wire storage module and the wire placing module and used for pre-treating the fiber wires; and a resin filling module forming a resin layer accommodating the carbon fiber sensitive element. The automated manufacturing apparatus can replace manual resin-coating and wire-placing processes, overcomes poor repeatability and low efficiency in production of sensors since too many manual uncontrollable factors are introduced, and is easy to achieve large-scale production.

Description

technical field [0001] The invention relates to the technical field of carbon fiber sensor manufacturing, in particular to an automatic manufacturing device for complex sensitive elements based on carbon fiber. Background technique [0002] Carbon Fiber (CF for short) is a new type of fiber material with high strength and high modulus fibers with a carbon content of more than 95%. Carbon fiber has many excellent properties, such as high axial strength and modulus, low density, high specific performance, no creep, ultra-high temperature resistance in non-oxidizing environment, fatigue resistance, good corrosion resistance, small thermal expansion coefficient and anisotropy And good electrical and thermal conductivity. The resistance of carbon fiber filaments increases proportionally with the strain under tensile strain, and decreases proportionally with the increase of strain under compressive strain, showing good electrical conductivity and piezoresistive effect, and has go...

[0005] However, the above method only refines the manufacturing process. At present, most of the smart layer grids are manufactured manually. The process is complicated and due to the introduction of too many uncontrollable human factors, the repeatability of the manufactured sensors is poor. Calibration is not easy to achieve batch production
