US 11,899,268 B2 · Optical lens, camera module and assembly method therefor

Abstract

An optical lens, comprising: a first lens component (100) comprising a first lens barrel (101) and at least one first lens sheet (102) mounted in the first lens barrel; a second lens component (200) comprising a second lens barrel (201) and at least one second lens sheet (202) mounted in the second lens barrel, the at least one second lens sheet and the at least one first lens sheet together constituting an imageable optical system; and an adhesive bonding the first lens component and the second lens component together, at least a part of the adhesive being interposed between a lens barrel and a lens sheet, wherein the statement of between the lens barrel and the lens sheet specifically means between the second lens barrel and the first lens sheet or between the first lens barrel and the second lens sheet. A corresponding assembly method for optical lens, a camera module, an optical lens and assembly method for camera module are further provided. The position shift of the lens sheet caused by the deformation of the lens barrel can be reduced, and the imaging quality of the optical lens or the camera module can be improved.

Dependent claims

An optical lens, comprising:

a first lens component comprising a first lens barrel and at least one first lens sheet mounted in the first lens barrel;
a second lens component comprising a second lens barrel and at least one second lens sheet mounted in the second lens barrel, the at least one second lens sheet and the at least one first lens sheet together constituting an imageable optical system, wherein there are a first gap and a second gap between the first lens component and the second lens component, and the first gap is closer to an outer side of the optical lens than the second gap;
and
an adhesive bonding the first lens component and the second lens component together, wherein the adhesive includes a first adhesive located in the first gap and a second adhesive located in the second gap;
wherein the second adhesive is interposed between and directly bonding a top surface of the second lens barrel and a bottom surface of the first lens sheet, or interposed between and directly bonding a bottom surface of the first lens barrel and a top surface of the second lens sheet.

An assembly method for optical lens, comprising:

pre-positioning a first lens component and a second lens component so that at least one second lens sheet of the second lens component and at least one first lens sheet of the first lens component together form an imageable optical system, the at least one first lens sheet being mounted in a first lens barrel of the first lens component, and the at least one second lens sheet being mounted in a second lens barrel of the second lens component, and forming a first gap and a second gap between the first lens component and the second lens component, wherein the first gap is closer to an outer side of the optical lens than the second gap;
adjusting and determining a relative position of the first lens component and the second lens component based on active alignment;
and
bonding the first lens component and the second lens component by an adhesive;
wherein the adhesive includes a first adhesive located in the first gap and a second adhesive located in the second gap;
wherein the second adhesive is interposed between and directly bonding a top surface of the second lens barrel and a bottom surface of the first lens sheet, or interposed between and directly bonding a bottom surface of the first lens barrel and a top surface of the second lens sheet.
