Lens module production device and method of manufacture thereof

Abstract

The invention relates to a lens module manufacture device and the manufacture method thereof; the lens module manufacture device comprises a lens (a separating cushion piece can be selected to match with the lens), a forming mould and moulding processes; wherein the lens can be the lenses in various catalogs; the separating cushion piece is equipped between the lenses; the forming mould comprises a mould cavity; the mould cavity consists of an upper film kernel, a lower film kernel, a left sliding block film kernel and a right sliding block film kernel (or the film kernel in other direction); cushioning devices can be equipped on the film kernel and under the film kernel; the cushioning devices are used to cushion the lens and the separating cushion piece and regulate the tolerances of the lens and the separating cushion piece; stop sliding blocks can be equipped on the front ends of the left and the right sliding block film kernels, which avoids the migration or the transplacement of the center line of the lens when the lens module is formed. The invention makes at least one lens and more than one separating cushion piece selected to match with the lens pass through a thermohardening or a thermoplastic forming mould and be processed into the lens module through an integral forming processing procedure.

Description

technical field [0001] The invention relates to a lens module manufacturing device and a manufacturing method thereof, in particular to an integral molding of a lens and a spacer through a molding die to produce a digital camera lens module or a mobile phone camera lens module. Background technique [0002] Existing camera lens modules are usually made by assembly, that is, placing the lens and spacer in the lens barrel, and applying glue to the periphery of the lens and spacer so that they can be tightly combined or fixed to the lens barrel. They are firmly bonded together to form a lens module. Although the existing method can complete the assembly of the lens module, it has the following disadvantages: [0003] When the lens and spacer are fixed to the lens barrel by gluing, due to the dimensional tolerance of each part or poor assembly technology, problems such as lens eccentricity or lens skew are likely to occur, thereby affecting the optical performance of the lens m...
