Attaching method and device

The invention provides an attaching method and device. The method comprises the following steps of providing a base plate and a cover plate; coating continuous film shaped liquid optical glue to the surface of the base plate; performing edge pre-curing on the base plate coated with the liquid optical glue; and enabling the base plate and the cover plate to be aligned and attached, and performing main curing on the base plate and the cover plate which are attached, wherein the edge pre-curing is used before the process that the base plate and the cover plate are aligned and attached, so that the liquid optical glue is prevented from overflowing, namely that pre-curing treatment is performed on the liquid optical glue distributed on the edge of the base plate; therefore, the liquid optical glue distributed on the edge of the base plate loses obvious flow properties and has sticking effects, in this way, before and in the process that the base plate and the cover plate are attached, the liquid optical glue locat
