The invention relates to an intelligent detection sensor for the spray nozzle blockage of a full-automatic glue sprayer, which is characterized in that a coating passage is arranged in a detection body and is used for connecting a spray coating pipeline with a spray nozzle; a cavity is arranged on the detection body, a detection hole which is communicated with the coating passage is arranged in the center of the bottom of the cavity and an elastic steel sheet is installed at the bottom of the cavity and is fastened through a flange; a body cover is closely jointed onto the detection body to form a sealed detection chamber; a strain sensor is arranged in the detection chamber, one end of the strain sensor is fixedly arranged on a raised platform on one side of the detection body, and the other end of the strain sensor is suspended in the air; the upper end of a detection screw is screwed onto the strain sensor, and the lower end of the detection screw is in close contact with the elastic steel sheet; and a circuit board is arranged right below the strain sensor and is installed on the detection body, and an analog-to-digital (A/D) conversion circuit on the circuit board is electrically connected with the strain sensor. The intelligent detection sensor for the spray nozzle blockage of the full-automatic glue sprayer has the advantages of strong corrosion resistance, high real-time detection performance, convenience in installation and the like, and can effectively solve the problem of the spray nozzle blockage of the full-automatic glue sprayer.
