Description
Technical field
The present invention relates to a kind of methods based on pre- focusing optimization camera module assembly.
Background technique
In existing camera module assembling process, usually first lens module and frame assembly are integrated, utilize sample
Product chip respectively focuses in advance to the lens module of various models, it is presetting it is defocused remove sample chip, then product image is installed
Sensor chip.When product image sensor chip is assembled with the frame with lens module, it is both needed to readjustment figure every time
As the alignment positional relationship of sensor chip and frame, assembly efficiency is lower.
Summary of the invention
The purpose of the present invention is to provide a kind of methods based on pre- focusing optimization camera module assembly, when shortening assembly
Between, improve assembly efficiency.
Based on considerations above, the present invention provides a kind of method based on pre- focusing optimization camera module assembly, including such as
Lower step: providing the frame with lens module, focused in advance to the lens module, saves the data letter of each focusing
Breath；When image sensor chip and frame assemble, information, adjusts pair of image sensor chip and frame based on the data
Image sensor chip and frame assembly are integrated, improve assembly efficiency by quasi- positional relationship.
Preferably, the data information memory of the pre- focusing is in database.
Preferably, during the pre- focusing, sample chip is provided, records location drawing picture clarity variation in focussing process
Data information；When assembling image sensor chip, the corresponding coding for placing lens module is searched, based on corresponding coding lookup
Correspond to the target data information in database to target lens module, be based on target data information, adjusts imaging sensor core
The alignment positional relationship of piece and frame improves assembly efficiency.
Method based on pre- focusing optimization camera module assembly of the invention, is first one by lens module and frame assembly
Body, record focusing data information when lens module is focused in advance are based on the tune when image sensor chip and frame assemble
Burnt data information adjusts the alignment positional relationship of image sensor chip and frame, when shortening the assembly of image sensor chip
Between, improve the assembly efficiency of camera module.
Detailed description of the invention
By Figure of description and then it is used to illustrate the specific reality of the certain principles of the present invention together with Figure of description
Mode is applied, other feature possessed by the present invention and advantage will be apparent or more specifically illustrated.
Fig. 1 is the schematic diagram of the method for the invention based on pre- focusing optimization camera module assembly.
Specific embodiment
In the following detailed description of the preferred embodiment, reference is constituted to the appended attached drawing of present invention a part.Institute

Exhaustive all embodiments according to the present invention.It is appreciated that without departing from the scope of the present invention, can use other
Embodiment can also carry out the modification of structure or logic.Therefore, it is below specific descriptions and it is unrestricted, and this
The range of invention is defined by the claims appended hereto.
Fig. 1 shows the method for the invention based on pre- focusing optimization camera module assembly, includes the following steps: to provide mirror
Lens module 10 and the assembly of frame 30 are integrated by head mould group 10, frame 30；Sample chip 20 is provided, sample chip 20 is adjusted
It with the alignment positional relationship of frame 30, is focused, is remembered in advance to the lens module 10 of various models respectively using sample chip 20
The data information for recording location drawing picture clarity variation in focussing process, preferably by the data information memory in database；
Then, when assembling product image sensor chip 20 ', the corresponding coding for placing lens module 10 need to be only searched, is based on corresponding to
Coding lookup is to target lens module 10(, that is, same model lens module 10) correspond to target data information in database,
It in other words, can be utilized based on the alignment positional relationship of target data information adjustment image sensor chip 20 ' and frame 30
Data information of the lens module 10 of same model during pre- focusing can simplify adjustment image sensor chip 20 ' and frame
The step of alignment positional relationship of frame 30, avoids installation every time from being both needed to readjust image sensor chip 20 ' and frame 30
It is directed at positional relationship, to conveniently and efficiently be integrated image sensor chip 20 ' and the assembly of frame 30, this method is shortened
The assembly time of image sensor chip 20 ' improves the assembly efficiency of camera module.
Method based on pre- focusing optimization camera module assembly of the invention, is first one by lens module and frame assembly
Body, record focusing data information when lens module is focused in advance are based on the tune when image sensor chip and frame assemble
Burnt data information adjusts the alignment positional relationship of image sensor chip and frame, when shortening the assembly of image sensor chip
Between, improve the assembly efficiency of camera module.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
How from the point of view of, the present embodiments are to be considered as illustrative and not restrictive.In addition, it will be evident that one word of " comprising " not
Exclude other elements and steps, and wording "one" be not excluded for plural number.The multiple element stated in device claim can also
To be implemented by one element.The first, the second equal words are used to indicate names, and are not indicated any particular order.
