Detailed description of the invention
Existing time of product development is long, and development cost is high.Inventor to prior art (technology known for inventor,
But not well known to others skilled in the art) research discovery, existing camera lens module, in preparation process, typically needs
Described first mirror plate layers, spacer shims, the second mirror plate layers passed sequentially through disposable glue and be bonded together, to be assembled into camera lens module,
The most described camera lens module is tested.Disposable glue is generally ultraviolet glue or hot-setting adhesive, the most bonding after, it is impossible to lossless
The carrying out of wound peels off.So after lens module group assembling, described first mirror plate layers, spacer shims, the second mirror plate layers just cannot be entered again
Row separates.If the result of test is undesirable, then need again to prepare described first mirror plate layers, spacer shims, the second eyeglass
Layer, and again described first mirror plate layers, spacer shims, the second mirror plate layers are bonded together, increase development cost and cycle.
Inventor furthers investigate discovery, causes the undesirable reason of result of test to be mainly described first eyeglass
Layer, matching degree between spacer shims and the second mirror plate layers are bad, between the most described first mirror plate layers and the second mirror plate layers between
Away from improper, or the shape of the lens of described first mirror plate layers and the second mirror plate layers is improper, causes in described camera lens module each
Do not mate between individual element.If the spacing between described first mirror plate layers and the second mirror plate layers is adjustable, and described first eyeglass
Layer and the shape of lens of the second mirror plate layers, then can be by adjusting between described first mirror plate layers and the second mirror plate layers between
Away from, and adjusting the shape of the lens of described first mirror plate layers and the second mirror plate layers so that test result meets the requirements, and saves exploitation
Cost and cycle.Inventor further study show that, if carried out between described first mirror plate layers, spacer shims, the second mirror plate layers
Bonding glue is for dissociating glue, then, when the result of test is undesirable, can make the described glue that can dissociate under given conditions
Lose viscosity, make described camera lens module separate, such that it is able to readjust described first mirror plate layers, spacer shims and the second mirror plate layers
Between matching degree.
According to the studies above, the present invention provides the preparation method of a kind of camera lens module, comprises the steps:
First mirror plate layers, spacer shims and the second mirror plate layers are provided；
Gluing will connect by first between described first mirror plate layers and spacer shims, by described spacer shims and the second mirror plate layers it
Between gluing connect by second, described first mirror plate layers, spacer shims and the second mirror plate layers are stacked into camera lens module, wherein, described
First glue is or/and the second glue is for dissociating glue；
Described camera lens module is tested, it is judged that whether test result meets the requirements, want if test result does not meets
Ask, then carry out rework operation, until test result meets the requirements；
Described rework operation includes:
Make the described glue that can dissociate lose viscosity under given conditions, make described camera lens module separate；
Adjust the matching degree between described first mirror plate layers, spacer shims and the second mirror plate layers, use the described glue weight that can dissociate
Newly stack, form the camera lens module after doing over again.
In described rework operation, the described glue that can dissociate can be made under given conditions to lose viscosity, make described camera lens mould
Group separates, thus adjusts the matching degree between described first mirror plate layers, spacer shims and the second mirror plate layers, such as, focus parameter
Deng, use the described glue that can dissociate to re-start stacking, form the camera lens module after doing over again, until described test result conforms to
Ask.Focal length parameter and optical quality the most preferably camera lens module can be adjusted quickly and easily, save the time, reduce cost.
