Description
Technical field
The present invention relates to optical image technology field, relates more specifically to optical lens assemble method and utilize this method group
Optical lens, the camera module of dress.
Background technology
With popularizing for mobile electronic device, the user that is used to help for being applied to mobile electronic device obtains image
The relevant technologies of the camera module of (such as video or image) have obtained swift and violent development and progress, and in recent years, take the photograph
It is widely applied as module is obtained in many fields such as medical treatment, security protection, industrial production.
In order to meet the more and more extensive market demand, high pixel, small size, large aperture is that existing camera module is irreversible
The development trend turned.Currently, market proposes the image quality of camera module higher and higher demand.Intended optical is influenced to set
The quality and the foozle during module packaging that the factor of the camera module resolving power of meter includes optical imaging lens.
Specifically, in the manufacturing process of optical imaging lens, influence camera lens resolving power factor come from each element and
The error and lens materials refractive index that the assembly of its error assembled, the error of eyeglass spacer element thickness, each eyeglass coordinates
Variation etc..Wherein, each element and its error of assembly include the optics face thickness of each lens monomer, lens optical face rise,
Eccentric between optical surface face type, radius of curvature, eyeglass single side and face, lens optical face tilts equal error, and the size of these errors takes
Certainly in mould and die accuracy and formed precision control ability.The error of eyeglass spacer element thickness depends on the machining accuracy of element.Respectively
The error of the assembly cooperation of eyeglass depends on being assembled the dimensional tolerance of element and the assembly precision of camera lens.Lens materials reflect
The stability and batch consistency that change introduced error and then depend on material of rate.
There is the phenomenon that accumulation deteriorates in the error of above-mentioned each elements affect resolving power, this cumulative errors can be with lens
Increasing for quantity and constantly increase.Existing resolving power solution is that the size of the element high to each relative sensitivity is carried out
Allowance control, eyeglass revolution compensate raising resolving power, but since the camera lens of high pixel large aperture is more sensitive, it is desirable that tolerance
It is harsh, such as：Part sensitivity camera lens 1um eccentricity of glasses lens can bring 9 ' image planes to tilt, and lead to machining eyeglass and assembling difficulty increasingly
Greatly, it simultaneously because feedback cycle is long in an assembling process, causes that the Measure of Process Capability (CPK) of lens assembling is low, fluctuation is big, leads
Cause fraction defective high.And as described above, because the factor for influencing camera lens resolving power is very more, it is present in multiple element, Mei Geyin
All there is the limit of the accuracy of manufacture in the control of element, if only promoting the precision of each element merely, hoisting power is limited, be promoted
It is with high costs, and the increasing image quality demand in market cannot be met.
On the other hand, in the process of camera module, the assembling process of each structural member (such as sensitive chip patch
Dress, motor camera lens lock process etc.) may all sensitive chip be caused to tilt, multinomial slant stack may lead to imaging modules
Parsing power cannot reach set specification, and it is low in turn result in module factory yields.In recent years, module factory passes through by imaging lens
When head and photosensitive module group assembling, the inclination of sensitive chip is mended by active calibration (Active Alignment) technique
It repays.However this technological compensa tion ability is limited.Since a variety of aberrations for influencing resolving power are from optical system (especially optics
Imaging lens) ability of itself, when the resolving power deficiency of optical imaging lens itself, existing photosensitive module active calibration work
Skill is difficult to compensate for.
To overcome drawbacks described above, it is currently suggested a kind of based on active calibration technique adjustment and determining upper and lower sub- camera lens
Then upper and lower sub- camera lens is bonded together according to identified relative position, and then produces complete optics by relative position
The assemble method of camera lens or camera module.This solution can promote the optical lens or camera module of mass production
Measure of Process Capability (CPK)；It enables to material (such as sub- camera lens for assembling optical lens or camera module or photosensitive
Component) the precision of each element and its requirement of assembly precision become loose, and then reduce optical imaging lens and camera shooting mould
The overall cost of group；The various aberrations of camera module can be corrected in real time in an assembling process, reduce fraction defective, be reduced
Production cost promotes image quality.
Since above-mentioned technology is the relative position for being primarily based on active calibration technique adjustment and determining upper and lower sub- camera lens, so
Upper and lower sub- camera lens is bonded together according to identified relative position using corresponding glue material afterwards, this can cause solid in glue material
Change the variation for the Performance of Optical System brought in the process.Specifically, in glue material cures deformation process, glue material can be formed lens barrel
Active force, the active force will cause lens barrel that undesirable deformation occurs, and then lead to the lens position being mounted in lens barrel hair
Changing.And glue material is thicker, above-mentioned undesirable deformation is bigger.This causes glue material that rear actual optical system is fully cured
There are deviations for the lens position of optical system determined by lens position and active calibration, and then it is pre- to cause image quality to be not achieved
Phase.Further, since the solidification process of glue material is toasted, so as to lead to the optical energy loss caused by baking
Consumption.Simultaneously as active calibration process and glue material solidification process are processes independently, therefore it is low to also cause production efficiency
The problem of.

It will be understood by those skilled in the art that into S110 → S130 → S140 → S120 can be changed the sequence in the above method
→ S150, that is, glue material can be laid again after active calibration process.However, it is understood that in the lens assembling method of the prior art
The step of between be serial, that is, pre-determined bit, active calibration process and glue material solidification process can not be performed simultaneously.
However, in glue material cures deformation process, glue material can form active force to lens barrel, which will cause lens barrel to be sent out
Raw undesirable deformation, and then the lens position being mounted in the lens barrel is caused to change, after this causes glue material to be fully cured
There are deviations for the lens position of optical system determined by the lens position and active calibration of actual optical system, and then cause
Expection is not achieved in image quality.Further, since the solidification process of glue material is toasted, so as to causing due to baking and
Caused optical property loss.Simultaneously as active calibration process and glue material solidification process are processes independently, therefore also
Cause the problem that production efficiency is low.
Fig. 2 shows the flow charts of optical lens assemble method according to an illustrative embodiment of the invention.Reference chart
2, include in process S200：
Step S210 prepares the first lens assembly and the second lens assembly, wherein the first lens assembly includes at least one
First eyeglass, and when the number of first eyeglass is multiple these first eyeglasses by be fitted into mutually keep each other it
Between relative position fix, the second lens assembly includes at least one second eyeglass, and when the second eyeglass number be it is multiple
When, the relative position between these second eyeglasses are kept by being fitted into mutually is fixed.Further, the second lens assembly
It may also include the second lens barrel, at least one second eyeglass is located in the second lens barrel.
Glue material is laid on the second lens assembly by step S220, wherein as needed, can glue material be laid in second
On the second lens barrel in lens assembly, or on second eyeglass that at least one of is laid in the second lens assembly.
Step S230 is pre-positioned the first lens assembly and the second lens assembly, makes at least one second eyeglass and at least one
A first eyeglass collectively forms imageable optical system.
Step S240 adjusts the position relationship between the first lens assembly and the second lens assembly by active calibration.
Step S250 applies curing reaction trigger condition, wherein step S250 can be with step S230 and step S240 simultaneously
Row executes, that is, can apply curing reaction trigger condition in the random time point in step S230 and step S240.In addition, solidification
Reaction trigger condition can be continuously applied in entire optical lens assembling process.
Step S260 waits for the glue material to complete solidification, obtains optical lens.
Further, in one embodiment, the glue material used in step S220 is the glue with delay curing property
Material.After being cured trigger condition effect (light, heat, oxygen, moisture etc.), glue material starts glue material with delay curing property
Slowly solidification (solidification rate is relatively low when beginning, and curing rate improves after a period of time).Therefore, show according to the present invention
In example property embodiment, used to have the complete solidification process of the glue material of delay property include low curing reaction stage and just
The normal curing reaction stage.That is, in the low curing reaction stage, glue material occur slow curing reaction (or curing reaction rate compared with
It is low), in the normal cure stage of reaction, normal cure reaction (or having normal curing reaction rate) occurs for glue material.In addition,
Glue material with delay curing property reaches the time being fully cured and can be designed according to the time used in active calibration,
So that before active calibration completion, glue is not fully cured, so as to adjust the first lens assembly and the second lens assembly it
Between relative position.That is, by using the glue material with delay curing property, can glue material the low curing reaction stage and/or
Active calibration process is carried out during the normal cure stage of reaction, at this point, the loss optical performance caused by glue curing can
It is solid to correct the bonding agent that existing AOA techniques can not correct to a certain extent to be compensated during active calibration
Change the Performance of Optical System variation brought.But this time is fully cured can not be long because this will so that production efficiency drop
It is low.That is, the time that is fully cured of the glue material with delay curing property is slightly longer than the time being pre-positioned with active calibration.
According to an illustrative embodiment of the invention, the glue material with delay curing property can be hot melt adhesive.At this
In, it is reaction by the hot melt adhesive that present invention is described according to an illustrative embodiment of the invention using hot melt adhesive as example
Type hot melt adhesive makes its crosslinking by introducing reactive active group into thermoplasticity macromolecular by active group reaction
Be cured to form three-dimensional structure, to form thermosetting resin, and then improve adhesive strength, heat-resisting, solvent resistant, drug-resistant and
The characteristics such as creep resistance.In the present embodiment, curing reaction trigger condition is heat, oxygen, ray (UV, electron beam etc.) and moisture
At least one of, but the invention is not restricted to this, other suitable curing reaction trigger conditions may be applicable to the present invention.At this
In embodiment, it is described in detail using moisture as reaction trigger condition.Specifically, first, Reactive hot melt adhesive is in high temperature
Lower fusing is laid in after becoming liquid on the second lens assembly, which is subject to moisture, and starts to cure, in low solidification
The stage of reaction and/or the normal cure stage of reaction, can be to the relative position between the first lens assembly and the second lens assembly
Active calibration is carried out, so as to improve the deterioration of the caused optical property in the solidification process of glue material.Simultaneously because hot melt adhesive is not
It needs baking further to cure (adhesive strength is enough) again, therefore reduces the optics that baking is brought relative to UV hot-setting adhesives
Performance variation.In addition, using hot melt adhesive allow glue material solidification process and pre-determined bit, active calibration concurrent process carry out and
Active calibration process and solidification process need not be executed successively, to improve production efficiency.
In addition to hot melt adhesive, the present invention used in glue material can be UV delay curings glue or other with delay curing property
Glue material.
Further, when the curing reaction trigger condition applied is moisture, after completing to lay glue material, due to sky
Moisture in gas always exists, therefore glue material is slowly cured at the very start.That is, the curing reaction trigger condition is persistently to apply
Add.
It further, can be after laying glue material to completion active when the curing reaction trigger condition applied is light
Arbitrary point irradiation light before calibration.Specifically, when the glue material used is UV delay curing glue, UV delay curing glue needs logical
The irradiation of UV light is crossed to trigger solidification.That is, irradiating UV by the random time point before terminating to active calibration after laying glue material
Light, UV delay curing glue start slowly to cure, but compared with solidification trigger condition is the example of moisture, it is only necessary to irradiate a UV
Light, without carrying out prolonged exposure.It will be appreciated, however, by one skilled in the art that the invention is not limited thereto, without departing substantially from this hair
It, can prolonged exposure UV light or repeatedly irradiation UV light as needed in the case of bright spirit and scope.In addition, people in the art
Member will be understood that light is not limited only to UV light, when using other kinds of delay glue, as long as the curing reaction of glue material can be triggered,
Just it can be used such as visible light or other kinds of light as curing reaction trigger condition.
Further, active calibration described herein can be in multiple degrees of freedom to the first lens assembly and second
The relative position of lens assembly is adjusted.Active calibration refers to the actual measurement resolving power according to optical system, controls a camera lens
Component could be adjusted to calibrate entire optical system relative to another lens assembly so that the axis trimming one of each lens assembly
It causes, and then the actual measurement resolving power of optical system is made to reach standard.Wherein, the axis of lens assembly refers to owning in lens assembly
The optical axis for the optical system that eyeglass is formed.
