Problems solved by technology

However, during the pushing process, it is difficult for the staff to precisely control the direction and depth of the pushing head
When the pushing direction of the pushing head deviates from the predetermined direction, it may cause the lens in the lens module to tilt, causing the optical axis of the lens to tilt, thereby affecting the optical performance of the lens module
When the pushing depth of the pushing head does not match the predetermined depth, it may cause errors in the assembly position of the lens in the lens module, which in turn affects the imaging position of the lens and affects the imaging quality of the lens module

Embodiment Construction

[0014] The assembly jig provided by the technical solution will be further described in detail below in conjunction with the accompanying drawings and multiple embodiments.

[0015] Please also refer to Figure 1 to Figure 4 The assembly jig 1 provided by the first embodiment of the technical solution is used for assembling the lens into the lens barrel, which includes a pressing rod 12 , an abutting member 14 and an elastic element 16 .

[0016] The pressing bar 12 includes a body 120 and a pushing head 122 . The body 120 is used for the staff to apply force, and the pushing head 122 is connected to one end of the body 120 for contacting the lens to push the lens. In this embodiment, the body 120 is cylindrical, and the pushing head 122 is also roughly cylindrical, and the body 120 and the pushing head 122 are arranged coaxially. Specifically, the pushing head 122 includes a cylindrical engaging portion 123 and a pressing portion 124 . The engaging portion 123 is connected...

Abstract

The invention provides an assembled fixture for assembling lens on a lens cone. The assembled fixture comprises a pressing rod, a propping piece, and an elastic element. The pressing rod comprises a body and a push head which is connected with one end of the body, wherein the push head is used for contacting the lens so as to push the lens. The propping piece is sleeved on the push head movably and is used for propping the lens cone; and the elastic element is arranged between the pressing rod and the propping piece and is used for performing elastic deformation along the axial direction of the pressing rod when the propping piece and lens cone are propped and the pressing rod moves relative to the propping piece along the axial direction. Therefore, the push head is exposed out of the propping piece.

Description

technical field [0001] The invention relates to lens module technology, in particular to an assembly jig for assembling a lens into a lens barrel. Background technique [0002] In recent years, with the development of multimedia technology, the scope of application of lens modules has become wider and wider, such as being applied to electronic products such as digital cameras, video cameras, and mobile phones with camera functions. While people are pursuing the miniaturization of digital cameras, video cameras and mobile phones with camera functions, they also put forward higher requirements for the image quality of the objects they shoot. It largely depends on whether the optical axes of the lenses in the lens module are aligned during the assembly process. In the paper "Zoom lens calibration for wind tunnel measurements" published by Alpheus et al. at the Fourth Conference of SPIE System and Image Metrology (VideometricsIV) in 1995, it was revealed that the optical axis o...
