Specific embodiment
Existing time of product development is long, and development cost is high.Inventor to the prior art (technology known for inventor,
But not for well known to others skilled in the art) the study found that existing lens module is during the preparation process, generally need
First mirror plate layers, spacer shims, the second mirror plate layers are passed sequentially through into disposable glue sticking, are assembled into lens module,
Then the lens module is tested again.Disposable glue is generally ultraviolet glue or hot-setting adhesive, can not be lossless after bonding
Wound remove.So after lens module group assembling, first mirror plate layers, spacer shims, the second mirror plate layers just can not again into
Row separation.If the result of test is undesirable, need to prepare first mirror plate layers, spacer shims, the second eyeglass again
Layer, and be again bonded together first mirror plate layers, spacer shims, the second mirror plate layers, increase development cost and period.
Inventor furthers investigate discovery, and the reason for causing the result of test undesirable is mainly first eyeglass
Matching degree between layer, spacer shims and the second mirror plate layers is bad, for example, between first mirror plate layers and the second mirror plate layers between
The shape of lens away from improper or described first mirror plate layers and the second mirror plate layers is improper, causes each in the lens module
It is mismatched between a element.If the spacing between first mirror plate layers and the second mirror plate layers is adjustable, and first eyeglass
The shape of layer and the lens of the second mirror plate layers, then can be by adjusting between first mirror plate layers and the second mirror plate layers
Away from, and the shape of the lens of first mirror plate layers and the second mirror plate layers is adjusted, so that test result meets the requirements, save exploitation
Cost and period.Inventor further study show that, if carried out between first mirror plate layers, spacer shims, the second mirror plate layers
The glue of bonding is that can dissociate glue, then when the result of test is undesirable, can make described can dissociate glue under given conditions
Viscosity is lost, separates the lens module, so as to readjust first mirror plate layers, spacer shims and the second mirror plate layers
Between matching degree.
According to the studies above, the present invention provides a kind of preparation method of lens module, includes the following steps:
First mirror plate layers, spacer shims and the second mirror plate layers are provided；
Will between first mirror plate layers and spacer shims by the first glue sticking, by the spacer shims and the second mirror plate layers it
Between by the second glue sticking, first mirror plate layers, spacer shims and the second mirror plate layers are stacked into lens module, wherein described
First glue or/and the second glue are that can dissociate glue；
The lens module is tested, judges whether test result meets the requirements, is wanted if test result is not met
It asks, then carries out rework operation, until test result meets the requirements；
The rework operation includes:
Glue can be dissociated described in making under given conditions and loses viscosity, separate the lens module；
The matching degree between first mirror plate layers, spacer shims and the second mirror plate layers is adjusted, dissociates glue weight using described
It is newly stacked, forms the lens module after doing over again.
In the rework operation, can make under given conditions it is described can dissociate glue and lose viscosity, make the camera lens mould
Group separation, so as to adjust the matching degree between first mirror plate layers, spacer shims and the second mirror plate layers, such as focuses parameter
Deng re-starting stacking using the glue that dissociates, form the lens module after doing over again, until the test result conforms to
It asks.It can quickly and easily adjust and discharge of the coke away from parameter and the preferable lens module of optical quality, save the time, reduce cost.
