The invention discloses a gluing head for a gluing device. The two-axis rotating gluing head for one-component glue comprises a gear C, a gear D, a motor B, a gear A, a gear B and a motor A, wherein the gear C, the gear D and the motor B enable a gluing unit to rotate in a vertical plane around a horizontal center line; and the gear A, the gear B and the motor A enable the gluing unit to rotate in a horizontal plane around a vertical center line. A connecting plate is fixedly installed on a base of the gluing device. A fixed plate B and the connecting plate are fixedly connected with the left side and the right side of a bearing block respectively, the left end of a rotating shaft penetrates inner holes of the gear C and a casing which are fixedly connected together, the casing is fixedly connected with a head body, the motor B is installed on the fixed plate B, the gear D is installed on the motor B, and the gear C is meshed with the gear D. By adoption of the gluing head, the two-axis or three-axis gluing device can finish gluing of plane and complex curved surface workpieces, the complex gluing device is not selected, the application range of the gluing device is expanded, the fabrication cost of the device is lowered, and the cost is reduced. The efficiency is improved obviously particularly when a large workpiece is glued.
