Description
Technical field
The utility model relates to optical image technology fields, specifically, the utility model relates to optical lens and camera shooting
Mould group.
Background technique
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
As mould group is all widely used 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 higher and higher demand to the image quality of camera module.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 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 cooperates
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 refraction
The introduced error of the variation of rate then depends on the stability and batch consistency of material.
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
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, it is present in multiple element, Mei Geyin because the factor for influencing camera lens resolving power very more
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 it is not able to satisfy the increasing image quality demand in market.
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.) it all may cause sensitive chip inclination, multinomial slant stack may cause imaging modules
Parsing power cannot reach set specification, and it is low in turn result in Mo Zu factory yields.In recent years, Mo Zu factory passes through by imaging lens
When head and photosensitive module group assembling, by active calibration (Active Alignment) technique to camera lens optical axis and sensitive chip optical axis
Opposite offset and inclination compensate.However this technological compensa tion ability is limited.Since a variety of aberrations for influencing resolving power come
Derived from the ability of optical system (especially optical imaging lens) itself, when the resolving power deficiency of optical imaging lens itself,
Existing photosensitive mould group active calibration technique is difficult to compensate for.
To overcome drawbacks described above, present applicant has proposed a kind of based on active calibration technique adjustment and determines upper and lower sub- mirror
Then upper and lower sub- camera lens is bonded together according to identified relative position, and then produces complete by the relative position of head
The assemble method of optical lens or camera module.This solution is able to ascend the optical lens or camera shooting mould of mass production
The Measure of Process Capability (CPK) of group；Enable to material (such as sub- camera lens for assembling optical lens or camera module or
Photosensory assembly) the precision of each element and its requirement of assembly precision become loose, and then reduce and optical imaging lens and take the photograph
As the overall cost of mould group；The various aberrations of camera module can be adjusted in an assembling process in real time, reduce fraction defective,
Production cost is reduced, image quality is promoted.However, active calibration and bonding based on upper and lower sub- camera lens are a kind of completely new lifes
Production. art will be realized reliable and stable mass production based on this production technology, still face lot of challenges.For example, utilizing glue
Material bonds the lens barrel of the sub- camera lens of upper and lower sub- camera lens, and glue material, which solidifies in deformation process, to form active force to lens barrel, should
Active force will lead to lens barrel and undesirable deformation occur, and then the lens shape and position being mounted in the lens barrel is caused to become
Change.Under this situation, glue material be fully cured rear actual optical system lens position and active calibration determined by optical system
There are deviations for the lens position of system, this may cause image quality and expection is not achieved.For another example the coefficient of expansion of glue material is fixed
, but the glue material being arranged between upper and lower sub- camera lens is often non-uniform that (such as upper and lower lens barrel generates excessive glue will lead to glue
Material uneven thickness), this is easy to cause lens barrel unbalance stress that deformation is caused in turn result in eyeglass variation, or may cause sub- mirror
Hair gives birth to positional shift.Problem above may cause image quality reduction.
