The invention provides accurate thread detecting equipment based on mechanical induction. The accurate thread detecting equipment is used for detecting whether threads of materials are qualified or not. The accurate thread detecting equipment includes a feeding mechanism, a material conveying mechanism, a detecting mechanism and a discharging mechanism; the feeding mechanism comprises feeding positions and is used for placing the materials on the feeding positions; the material conveying mechanism is used for conveying the materials; the detecting mechanism is used for detecting the threads ofthe materials; and the discharging mechanism is used for classifying and discharging the detected materials. The accurate thread detecting equipment can realize the automatic detecting operation of the threads of the materials without the need for manual operation, the detection efficiency can be significantly improved, the detection cost is reduced, meanwhile, the detection accuracy can furtherbe improved, in addition, the cooperation of the material conveying mechanism and the discharging mechanism of the detecting equipment realizes the accurate and efficient classification and discharging of qualified products and unqualified products, and the reliability and stability of the overall detecting equipment are high.
