Description
Technical field
The utility model relates to optical image technology fields, specifically, the utility model relates to optical lens, 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 are that existing camera module is irreversible
The development trend turned.However, to realize that high pixel, small size, the demand of three aspects of large aperture are that have in same camera shooting molding
Great difficulty.For example, the increase of the compact development and Mobile phone screen accounting of mobile phone, allows interior of mobile phone to can be used in preposition camera shooting
The space of mould group is smaller and smaller, and market has also been proposed higher and higher demand to the image quality of camera module.
In compact camera module (such as camera module for mobile phone) field, generally require in view of optical imaging lens
The quality and the foozle during module packaging of head.Specifically, in the manufacturing process of optical imaging lens, mirror is influenced
Head resolving power factor is matched from the assembly of each element and its error of assembly, the error, each eyeglass of eyeglass spacer element thickness
The error of conjunction and the variation of lens materials refractive index etc..Wherein, each element and its error of assembly include each lens monomer
Eccentric between optics face thickness, lens optical face rise, optical surface face type, radius of curvature, eyeglass single side and face, lens optical face is inclined
The size of oblique equal error, these errors depends on mould and die accuracy and formed precision control ability.The mistake of eyeglass spacer element thickness
Difference depends on the machining accuracy of element.The error of the assembly cooperation of each eyeglass depends on the dimensional tolerance and mirror that are assembled element
The assembly precision of head.The introduced error of variation of lens materials refractive index then depend on material stability and batch it is consistent
Property.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 numbers
Increase and constantly increase.Existing resolving power solution is to carry out tolerance for the size of the element high to each relative sensitivity
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 is tight
Severe, such as: part sensitivity camera lens 1um eccentricity of glasses lens can bring 9 ' image planes to tilt, and cause machining eyeglass and assembling difficulty increasing,
Simultaneously because feedback cycle is long in an assembling process, cause that the Measure of Process Capability (CPK) of lens assembling is low, fluctuation is big, causes
Fraction defective is high.And as described above, it is present in multiple element, each factor because the factor for influencing camera lens resolving power very more
Control all there is the limit of the accuracy of manufacture, if only promoting the precision of each element merely, hoisting power is limited, promoted at
This is high, and is not able to satisfy the increasing image quality demand in market.
Present applicant has proposed a kind of based on active calibration technique adjustment and determines the relative position of upper and lower sub- camera lens, so
Upper and lower sub- camera lens is bonded together according to identified relative position afterwards, and then produces complete optical lens or camera shooting
The assemble method of mould group.The process capability of optical lens or camera module that this solution is able to ascend mass production refers to
Number (CPK)；It enables to each of material (such as sub- camera lens or photosensory assembly for assembling optical lens or camera module)
The precision of a element and its requirement of assembly precision become loose, so reduce optical imaging lens and camera module integral into
This；The various aberrations of camera module can be adjusted in an assembling process in real time, reduce fraction defective, reduce production cost,
Promote image quality.
However, carrying out active calibration to optical system of camera lens itself is a kind of new production technology, practical volume production needs
Consider the factors such as reliability, crash resistance, weatherability and the cost of manufacture of optical lens and camera module, also needs sometimes
Yield it can not decline caused by survey factor in face of various.For example, in a kind of process program, in the first lens assembly and second
Glue material is filled between lens assembly, so that the first lens assembly and the second lens assembly are maintained at opposite determined by active calibration
Position.However practical test manufacture discovery, optical lens compared with the image quality of camera module the active calibration stage it is obtained at
As quality usually deteriorates, this deterioration exceeds tolerance sometimes, causes product bad.Applicants have found that
In the assembling of optical lens or camera module introduce active calibration technique after, glue material, lens barrel or eyeglass variation and it is other not
Master factor may be the reason of leading to the above problem.Currently there is an urgent need to which the solution of the above problem can be overcome, so as to
Promote product yield.

Fig. 8 is the schematic top plan view that the utility model embodiment is poured the first lens barrel 102.With reference to Fig. 8, in general, being molded
When forming the first lens barrel 102, cast gate 1021 is as pouring into the channel of the plastics of hot melt, by being cooled and shaped, cast gate 1021 and more
The remaining plastics that molding plastics carry out between excision and the first lens barrel 102 that do not carry out need to cut off, and are located to be formed
The cut sides 3000 of first lens barrel, 102 end.In addition in this process, the size of the first lens barrel 102 is because expanding with heat and contract with cold and can send out
Changing, wherein shrinking percentage is small, therefore change in size is small because wall thickness is relatively thin near cut sides 3000；Simultaneously as
Far from the pressure loss at 1021 part of cast gate, cause the shrinkage ratio of the part far from incision at cast gate 1021
Partial shrinking percentage is big.Same principle, there is also similar problems in casting process for the first eyeglass 101.Fig. 9 A is this reality
The cross-sectional view being poured with the first eyeglass of new embodiment 101, Fig. 9 B is 101 castable of the first eyeglass of the utility model embodiment
Top view afterwards.With reference to Fig. 9 B, the first eyeglass 101 has cut sides 2000.Based on same former with the first lens barrel of casting 102
Reason, the first eyeglass 101 have larger shrinking percentage at separate cut sides 2000.Referring still to Fig. 5 B, further, in the implementation
In example, first eyeglass 101 has the first optics area 1011 and first structure area 1012, and first structure area 1012, which has, to be extended
Portion.First eyeglass 101 is formed by Shooting Technique and the lateral surface of first eyeglass 101 has eyeglass cut sides
2000, the eyeglass cut sides 2000 be cut off the first structure area 1012 cast gate 1015 and formed cut sides.It is described
First lens barrel 102 is formed by Shooting Technique and the lateral surface of first lens barrel 102 has lens barrel cut sides 3000, described
Lens barrel cut sides be cut off first lens barrel 102 gate portions 1021 and formed cut sides.Gate portions are injection molding works
For injecting part corresponding to the inlet of liquid condition shaping material in skill.In the present embodiment, the eyeglass cut sides 2000 are set
It sets in the side opposite with the lens barrel cut sides 3000, i.e. the big one end of the shrinking percentage of the first lens barrel 102 is arranged in the first mirror
Big one of 101 shrinking percentage of the first eyeglass is arranged in the small one end of 101 shrinking percentage of piece, the small one end of the shrinking percentage of the first lens barrel 102
