The present invention relates to a glue spray device, which sprays glue to an object to be attached, comprising: a main body installed on an attaching device; a spray nozzle part installed on the main body to spray glue to an object to be attached that is placed below; and a laser head installed on the main body to modify the surface of the object to be attached via laser radiation before spraying glue to the object to be attached. According to the present invention, the glue is made to have excellent adherence strength by improving the surface penetration of the glue via surface modification by laser even if a film or a coating surface exists on the surface of the object to be attached. The reliability of the opening and closing operation of glue spray can be improved using a coil. The spray amount of the glue is adjusted easily by the precise operation of a handle. The installation space of a trigger sensor is ensured easily by integrally mounting the trigger sensor for detecting the object to be attached. The position of the trigger sensor is adjusted conveniently. A line for a part to be modified by laser and a glue spray line can be controlled automatically to be the same by integrally modularizing the laser head and the spray nozzle part. The quality of a product can be maintained or improved. A surface required to be modified can be modified with various patterns on differently from general linear line modification. |
