Abstract
A lens assembly is disclosed, which includes a base and a lens barrel. The base has a front edge, a back edge opposite to the front edge and a passage penetrating the front edge and the back edge. The lens barrel is disposed in the passage and includes a lens and a lens holding member holding the lens, wherein an outer surface of the lens holding member is in contact with an inner wall of the passage, and at least one of the inner wall of the passage and the outer surface of the lens holding member includes a smooth surface, arranged such that a thrust force applied on the lens barrel while assembling the lens assembly causes a sliding movement between the base and the lens barrel on the smooth surface.
Claims19
A lens assembly, comprising:
- a base having a front edge, a back edge opposite to the front edge and a passage penetrating the front edge and the back edge;
- and
- a lens barrel disposed in the passage and comprising a lens and a lens holding member holding the lens, wherein an outer surface of the lens holding member is in contact with an inner wall of the passage, and the outer surface of the lens holding member comprises a uniform surface extending from a front end of the lens holding member to a rear end of the lens holding member, arranged such that a thrust force applied on the lens barrel while assembling the lens assembly causes a sliding movement between the base and the lens barrel on the uniform surface,
- wherein the base has at least one groove disposed on the front edge and connected to the passage, and an adhesive is applied in the groove to fix the lens barrel.
A method for assembling a lens assembly, comprising:
- providing a base with a passage;
- placing a lens barrel in the passage of the base;
- moving a pin to provide a thrust force on the lens barrel and cause a sliding movement between the base and the lens barrel;
- fixing the lens barrel by an adhesive provided between the lens barrel and the base;
- and
- removing the pin to complete the lens assembly.
A lens assembly, comprising:
- a base having a front edge, a back edge opposite to the front edge and a passage penetrating the front edge and the back edge, wherein the base comprises a protrusion protruding from the inner wall of the passage, and the protrusion has a plurality of insertion holes respectively penetrated through the protrusion along a direction parallel to a longitudinal axis of the passage;
- and
- a lens barrel disposed in the passage and comprising a lens and a lens holding member holding the lens, wherein an outer surface of the lens holding member is in contact with an inner wall of the passage, and the inner wall of the passage comprises a uniform surface connecting the front edge to a surface of the protrusion, arranged such that a thrust force applied on the lens barrel while assembling the lens assembly causes a sliding movement between the base and the lens barrel on the uniform surface.
