The invention relates to the technical field of shoemaking, and particularly relates to a 3D visual outsole glue spraying workstation and a using method thereof. The 3D visual outsole glue spraying workstation is characterized in that the 3D visual outsole glue spraying workstation comprises a support frame, an intelligent manipulator, a photoelectric sensor, a conveying platform, an electric control cabinet and a 3D contour scanner, wherein the electric control cabinet is arranged on one side of the support frame, the 3D contour scanner is arranged right above the feeding end of the conveyingplatform, the photoelectric sensor is fixedly arranged at the feeding end of the conveying platform, the intelligent manipulator is arranged on the inner top surface of the support frame, the conveying platform is horizontally arranged below the intelligent manipulator, a glue spraying gun is arranged on the claw seat at the tail end of the intelligent manipulator,a plurality of glue outlet smallopenings for spraying glue independently are formed in the glue spraying gun, and a cleaning device for cleaning the head of the glue spraying gun is arranged on one side of the support frame. According to the 3D visual outsole glue spraying workstation and the using method thereof, the overall structure is novel, the head of the glue spraying gun can be cleaned in time, and the spraying amount of glue is conveniently controlled; and in addition, the effect of spraying different types of glue can also be achieved.
