Lens group and lamination method thereof

A lamination method is used for laminating a first lens and a second lens, wherein the first lens is provided with a concave surface, the second lens is provided with a convex surface. The laminationmethod comprises the following steps of coating an edge of one of the concave surface and the convex surface with frame glue; initiatively aligning the first lens and the second lens, and laminating the concave surface of the first lens and the convex surface of the second lens to form the lens group by the frame glue; curing the frame glue to form a baffle wall, wherein the concave surface and the convex surface of the lens group and the baffle wall form a glue injection space with an injection hole; injecting liquid-state optical transparent glue to the glue injection space; and sealing theinjection hole of the baffle wall by sealing glue. By the lamination method, the problem of lamination press uniformity is solved, and an initiative alignment result is prevented from being affected. 一种贴合方法系用于贴合第一镜片与第二镜片。第一镜片具
