Problems solved by technology

However, since the contact surfaces between the lens barrel and the fixed ring are all smooth surfaces, and the fixed ring is prone to deflection when the fixed ring is assembled on the lens barrel, the gaps between the fixed ring and the lens barrel are of different sizes, and The melting state of each point between the fixing ring and the lens barrel is uneven
The joining strength of this method is not enough, and the fixing ring is easy to move or fall off from the lens barrel, which affects the arrangement of the optical lens in the lens barrel, or even disintegrates the lens

Abstract

The invention discloses an optics lens including a lens barrel, a fixing ring and at least one optics lens element. A joint surface is arranged along the inner edge of one end of the lens barrel. Thejoint surface is provided with a plurality of microstructures arranged on a circle. The microstructures are convex on the joint surface. The fixing ring is arranged in the joint surface of the lens barrel. The optics lens elements are arranged in the lens barrel. The microstructures and the fixing ring on the joint surface are dissolved by using a solvent to fixedly arrange the optics lens elements in the lens barrel. Furthermore, the invention also provides an assembly method and lens barrel of the optics lens. The optics lens with high reliability and durability can be manufactured accordingto the invention.

Description

technical field [0001] The present invention relates to an optical element and its assembly method, and in particular to an optical lens, its assembly method and lens barrel. Background technique [0002] Optical lens In order to fix the optical lens in the lens barrel, a fixing ring is placed on the outermost side of the optical lens, and then a solvent point is placed between the joint surface of the lens barrel and the fixing ring to make it fused. However, since the contact surfaces between the lens barrel and the fixed ring are all smooth surfaces, and the fixed ring is prone to deflection when the fixed ring is assembled on the lens barrel, the gaps between the fixed ring and the lens barrel are of different sizes, and The melting state of each point between the fixing ring and the lens barrel is uneven. The joining strength of this method is not enough, and the fixing ring is easy to move or fall off from the lens barrel, which affects the arrangement of the optical ...
