The accompanying drawings illustrate, by way of example, specific embodiments in which the invention may be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments according to the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims.
Fig. 1 shows a method for optimizing camera module assembly based on pre-focusing according to the present invention, comprising the following steps: providing a lens module 10 and a frame 30, and assembling the lens module 10 and the frame 30 into a whole; providing a sample chip 20, adjusting the alignment position relationship between the sample chip 20 and the frame 30, pre-focusing the lens modules 10 of various models by using the sample chip 20, recording data information of the sharpness change of a position image in the focusing process, and preferably storing the data information in a database; therefore, when assembling the production image sensor chip 20', only the corresponding code of the lens module 10 is searched, the target lens module 10 (i.e. the lens module 10 of the same model) is searched corresponding to the target data information in the database based on the corresponding code, that is, the alignment relationship between the image sensor chip 20 'and the frame 30 can be adjusted based on the target data information, that is, the step of adjusting the alignment relationship between the image sensor chip 20' and the frame 30 can be simplified by using the data information of the lens modules 10 of the same model in the pre-focusing process, and the alignment relationship between the image sensor chip 20 'and the frame 30 needs to be readjusted every time of installation is avoided, so that the image sensor chip 20' and the frame 30 can be conveniently and quickly assembled into a whole, the method shortens the assembly time of the image sensor chip 20' and improves the assembly efficiency of the camera module.
The method for optimizing the assembly of the camera module based on the pre-focusing firstly assembles the lens module and the frame into a whole, records focusing data information when the lens module is pre-focused, and adjusts the alignment position relation between the image sensor chip and the frame based on the focusing data information when the image sensor chip is assembled with the frame, thereby shortening the assembly time of the image sensor chip and improving the assembly efficiency of the camera module.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
