Abstract
The invention discloses a focusing-free optical camera module which comprises a camera lens and an image chip, wherein the camera lens is formed by cutting a lens group comprising a plurality of lenses and directly bonded on the image chip through glue; and the distance between the surface of a lens close to the image chip in the lens group of the camera lens and the image chip is smaller than 100 millimeters. In the invention, a focusing procedure of a traditional focus camera module is saved, so that a space ring is not needed to be bonded between the camera lens and the image chip, the space ring thickness tolerance (+/-10 millimeters) brought while manufacturing the space ring is removed, the manufacturing yield is improved, the whole process procedure is shortened, man power, material resources and manufacturing time are saved, and the purpose of guaranteeing high image quality of the optical camera module while not focusing is achieved.
Description
Technical field
The present invention relates to optics camera field, especially a kind of optics camera module of exempting to focus.
Background technology
Lead down in 3G communication and the contour new ideas of Internet of Things, the optics camera is not only at mobile phone, and traditional field widespread uses such as notebook computer at toy, are used also more and morely in the various digital devices such as household electrical appliances.
Optics camera module industry is the industry of a sufficient competition, the product of high-performance low price (high performance-price ratio just) is the trump card that enterprise gets the upper hand of in the dog-eat-dog competition of market, the required headcount of tradition focusing processing procedure account for the entire module processing procedure always need headcount 2/3rds more than, and there is FEOL to lean on equipment back-end process saying by manpower, required manpower and materials are bigger, and production cost is higher.Though the automatic focusing board is arranged now on the market, one comes the unit price costliness, and two come the board instability, imports difficulty, and it is not remarkable to produce effects.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of optics camera module of exempting to focus, can save manufacturing cost: manpower and material resources, and can shorten manufacturing time, and can be implemented in the high image quality that guarantees optics camera module when exempting to focus.
The present invention for the technical scheme that solves its technical matters and adopt is:
A kind of optics camera module of exempting to focus, comprise camera lens and image chip, described camera lens is formed by the lens set cutting that comprises a plurality of eyeglasses, camera lens directly sticks on the image chip by glue, in the lens set of this camera lens near the lens surface of image chip and the spacing between the image chip less than 100 microns (during this optical lens design in the high-quality while of guaranteed performance, it is burnt to shorten its machinery back, the lens surface of close image chip and the spacing between the image chip are less than 100 microns in the realization lens set, keep the burnt spacer ring in back between script camera lens and the image chip so that can remove, thereby removed the spacer ring thickness deviation of bringing into when making spacer ring (± 10 microns), like this by camera lens is directly adhered to the optics camera module that produces on the image chip with glue, when reaching the effect of exempting to focus, guaranteed that the optics camera module of exempting to focus has high picture quality).
As a further improvement on the present invention; described camera lens by the structure that glue directly sticks on the image chip is: described camera lens sticks in by glue on the cover glass of image chip, and the lens surface of close cover glass and the spacing between the cover glass are less than 100 microns in the lens set of this camera lens.
As a further improvement on the present invention, described camera lens for by a plurality of optical resin aspherical lens by spacer ring at interval the lens set cutting that constitutes by the glue adhesion of back form exempt from the optical lens of focusing.
It is burnt that the present invention has shortened the machinery back of camera lens: make in the lens set of camera lens near the lens surface of cover glass and the spacing between the cover glass less than 100 microns; and camera lens is cageless directly to be adhered on the image chip; the focusing processing procedure that has saved traditional focusing camera module; because of need not adhesion spacer ring between camera lens and image chip; remove the spacer ring thickness deviation of bringing into when making spacer ring (± 10 microns) and improved the making yield; and shortened whole manufacturing process; saved manpower; material resources and manufacturing time can be implemented in the high image quality that guarantees optics camera module when exempting to focus.
The invention has the beneficial effects as follows: it is burnt that the present invention has shortened the machinery back of camera lens: the lens surface of close cover glass and the spacing between the cover glass are less than 100 microns in the lens set of camera lens; and camera lens directly is adhered on the image chip; the focusing processing procedure that has saved traditional focusing camera module; because of need not adhesion spacer ring between camera lens and image chip; remove the spacer ring thickness deviation of bringing into when making spacer ring (± 10 microns) and improved the making yield; and shortened whole manufacturing process; saved manpower; material resources and manufacturing time can be implemented in the high image quality that guarantees optics camera module when exempting to focus.

Embodiment
Embodiment: a kind of optics camera module of exempting to focus, comprise camera lens 1 and image chip 3, described camera lens 1 is formed by the lens set cutting that comprises a plurality of eyeglasses, camera lens 1 directly sticks on the image chip 3 by glue 2, in the lens set of this camera lens 1 near the lens surface of image chip 3 and the spacing 6 between the image chip 3 less than 100 microns (when this optical lens designs in the high-quality while of guaranteed performance, it is burnt to shorten its machinery back, the lens surface of close image chip 3 and the spacing between the image chip 3 are less than 100 microns in the realization lens set, keep the burnt spacer ring in back between script camera lens 1 and the image chip 3 so that can remove, thereby removed the spacer ring thickness deviation of bringing into when making spacer ring (± 10 microns), like this by camera lens 1 usefulness glue directly being adhered to the optics camera module that produces on the image chip 3, when reaching the effect of exempting to focus, guaranteed that the optics camera module of exempting to focus has high picture quality).
Described camera lens 1 by the structure that glue 2 directly sticks on the image chip 3 is: described camera lens 1 sticks in by glue 2 on the cover glass 5 of image chip 3, and the lens surface of close cover glass 5 and the spacing 6 between the cover glass 5 are less than 100 microns in the lens set of this camera lens 1.
Described camera lens 1 for by a plurality of optical resin aspherical lens by spacer ring at interval the lens set cutting that constitutes by the glue adhesion of back form exempt from the optical lens of focusing.
It is burnt that the present invention has shortened the machinery back of camera lens 1: make in the lens set of camera lens 1 near the lens surface of cover glass 5 and the spacing 6 between the cover glass 5 less than 100 microns; and camera lens 1 cageless directly being adhered on the image chip 3; the focusing processing procedure that has saved traditional focusing camera module; because of need not adhesion spacer ring between camera lens 1 and image chip 3; remove the spacer ring thickness deviation of bringing into when making spacer ring (± 10 microns) and improved the making yield; and shortened whole manufacturing process; saved manpower; material resources and manufacturing time can be implemented in the high image quality that guarantees optics camera module when exempting to focus.
