Abstract
A dustproof structure of a mobile phone camera module comprises a lens cone and a lens seat combined with the lens cone, wherein external threads are arranged on the lateral wall of the lens cone; internal threads are correspondingly arranged on the lateral wall of the lens seat; and a lens is arranged on the lens cone. When the lens focuses, the lens cone turns in the backward spinning rotation direction, and the lens moves in the upward rotation direction. Based on the correction to the defect that small particles can fall off from the threads by the forward spinning rotation of the lens, the smudginess-prevention structure of the backward spinning lens is designed for the dustproof structure of the mobile phone camera module, small particles generated by the friction between threads can be led to the upper part without falling off, and even if part of the small particles fall off, the particles can be caught by a dust board on the lens cone so that the particles have no chance of falling onto the CCD surface, thereby effectively solving the polluted problem of an image.
Description
Technical field
The utility model relates to a kind of dustproof construction of cell-phone camera module, relate in particular to a kind of CSP (Chip Scale Package that is applied to comprise, wafer-level package) and the dustproof construction of the cell-phone camera module of COB (Chip On Board, by binding the IC nude film is fixed on the printed-wiring board (PWB)) machine.
Background technology
Along with market demand increases day by day, the development of cell-phone camera module is very rapid, and is correspondingly, more urgent to the production capacity requirement of cell-phone camera module.In order to improve the production capacity of cell-phone camera module, except that increase equipment and manpower, what is more important reduces the fraction defective of product.Up to the present, cause the high always reason of fraction defective of module only to have a bit, i.e. the dirty problem of image.And cause the dirty basic factor of image is exactly molecule.The dextrorotation lens construction of former cell-phone camera module is when assembling and focusing, and the camera lens that mutual fricative molecule is rotated down between screw thread takes CCD (Charge Coupled Device, Charge Coupled Device (CCD)) surface to, causes the product image dirty.Therefore, how to design the cell-phone camera modular structure that makes new advances, fricative molecule between screw thread is the problem of the common concern of those skilled in the art institute when improve self assembly and focusing.
Summary of the invention
The utility model purpose is to provide a kind of dustproof construction of cell-phone camera module, and it adopts the derotation lens construction, to solve the dirty problem of image.
For achieving the above object, the utility model provides a kind of dustproof construction of cell-phone camera module, comprising: lens barrel and the microscope base that is equipped with lens barrel, and the lens barrel sidewall is provided with external thread, and correspondence is provided with internal thread on the microscope base sidewall; Lens barrel is provided with camera lens, and during the camera lens focusing, the lens barrel rotation direction is derotation, and lens barrel direction of motion makes progress for rotation.
The beneficial effects of the utility model: the dustproof construction of cell-phone camera module of the present utility model can cause screw thread the drop defective of molecule and the anti-dirty structure of the derotation camera lens that designs based on improving the dextrorotation camera lens, can be upward with the molecule band that rubs out between screw thread, and can not drop downwards, even there is the part molecule to drop, also can be stopped and make particle have no chance to fall within the CCD surface, can effectively solve the dirty problem of image by the dust board on the lens barrel.
For further setting forth the utility model is technological means and the effect that the predetermined purpose of realization is taked, see also following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and characteristics, should obtain thus going deep into and concrete understanding, yet accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.
Description of drawings
Below in conjunction with accompanying drawing, by embodiment of the present utility model is described in detail, technical scheme and other beneficial effects of utility model are apparent with making.
In the accompanying drawing,
Fig. 1 is the synoptic diagram of the dustproof construction of the utility model cell-phone camera module.
Embodiment
As shown in Figure 1, the dustproof construction of the utility model cell-phone camera module comprises: lens barrel 2 and the microscope base 4 that is equipped with lens barrel 2, and lens barrel 2 sidewalls are provided with external thread 22, and correspondence is provided with internal thread 42 on microscope base 4 sidewalls.Lens barrel 2 is provided with camera lens 21, and during camera lens 21 focusing, lens barrel 2 rotation directions are derotation, and lens barrel 2 direction of motion make progress for rotation.In addition, the side wall lower ends of lens barrel 2 stretches out dust-blocking plate 23 is set.
During installation, lens barrel 2 is inserted in from microscope base 4 belows, during focusing lens barrel 2 is rotated up to get final product.This structure can reduce the probability that drops to the CCD surface with fricative molecule band between lens barrel 2 and microscope base 4 screw threads to microscope base 4 tops.
Except that above-mentioned 2 differences, the dustproof construction of cell-phone camera module of the present utility model is identical with existing cell-phone camera module, thereby its image quality and outward appearance to the shooting module all has no effect.
Anti-dirty principle of the present utility model: during camera lens 21 focusing, friction produces molecule between the screw thread of lens barrel 2 and microscope base 4, molecule is upwards taken out of by lens barrel 2, and the only a few molecule drops on the dust-blocking plate 23 of lens barrel 2, has reduced effectively the dirty probability of image to occur.
And, when the dustproof construction of concrete application cell-phone camera module of the present utility model, also can remake further improvement: such as, on the screw thread of microscope base 4, be coated with damping oil, reduce friction and produce the quantity of molecule, and for example: also can be coated with damping oil at dust board 23, make it not removable in order to cling the molecule that drops.
The beneficial effects of the utility model: the dustproof construction of cell-phone camera module of the present utility model can cause screw thread the drop defective of molecule and the anti-dirty structure of the derotation camera lens that designs based on improving the dextrorotation camera lens, can be upward with the molecule band that rubs out between screw thread, and can not drop downwards, even there is the part molecule to drop, also can be stopped and make particle have no chance to fall within the CCD surface, can effectively solve the dirty problem of image by the dust board on the lens barrel.
Above-described only is preferred embodiment of the present utility model, every various modifications of doing according to the utility model with change the protection domain that all should belong to claim of the present utility model.
