Description

Digital camera lens module and assemble method thereof

[technical field]

The invention relates to a kind of digital camera lens module and assemble method thereof, especially about a kind of digital camera lens module and assemble method thereof that is used for portable electron device.

[background technology]

Along with the continuous development of science and technology, portable electron device such as mobile phone are used increasingly extensively, also day by day trend towards simultaneously light and handy, attractive in appearance and multifunction, and wherein camera function is the additional function of new development mobile phone in recent years.Follow the economic globalization development, the market competition aggravation, for reducing the portable telephone device cost of tool camera function, its production cycle becomes one of principal element of enterprises pay attention.

The digital camera lens module is when assembling, need dress school and debugging, purpose is to obtain suitable focal length, existing mobile phone generally is designed to helicitic texture with the digital camera lens module, lens barrel is an external thread, microscope base is an internal thread, adjust focal length by the rotation lens barrel during this camera lens assembling, after treating that focal length calibration is good, point glue is fixed this lens barrel and microscope base, yet the external thread of screw thread lens barrel and screw thread microscope base and internal thread accuracy requirement are higher, and processing is comparatively complicated, development time is longer, thereby has increased digital camera lens module manufacturing cost.In the assembling process, connection of thread is worked repeatedly between lens barrel and the microscope base, and this assemble method comes off because of the phase mutual friction easily causes the connection of thread material surface, and clan's ash phenomenon in the camera lens takes place, and influences the cleanliness in the camera lens, thereby influences image quality.

In view of above shortcoming, provide a kind of and process the digital camera lens module simple, that the construction cycle is short and cost is low and assemble very necessity of the assemble method simple, that the interior cleanliness of camera lens are high.

[summary of the invention]

The object of the present invention is to provide a kind of digital camera lens module simple, that the construction cycle is short and cost is low of processing.

Another object of the present invention is to provide a kind of simple, interior high digital camera lens module group assembling method of cleanliness of camera lens of assembling.

Digital camera lens module of the present invention comprises a lens barrel and a microscope base, has pin-and-hole on this lens barrel circumferential wall, this microscope base has sleeve, described lens barrel is contained in this sleeve, offers elongate slots on the sleeve wall, and this elongate slots Origin And Destination has along the relative displacement of sleeve axial direction.

Digital camera lens module group assembling method of the present invention may further comprise the steps: a digital camera lens module is provided, and this digital camera lens module comprises a lens barrel and a microscope base, has pin-and-hole on this lens barrel circumferential wall; This microscope base has sleeve, offers elongate slots on the sleeve wall, and this elongate slots Origin And Destination has along the relative displacement of sleeve axial direction; Lens barrel is placed in the sleeve of microscope base, the pin-and-hole of lens barrel is facing to the elongate slots on the microscope base; One latch is provided, and described latch inserts on the pin-and-hole by elongate slots, and latch one end supports in the pin-and-hole bottom, and the other end exposes from elongate slots; Stir latch, it slides along elongate slots, and latch drives lens barrel and rotates; Point glue is microscope base and lens barrel fixedly.

Compare prior art, it is simple that numerical camera mould of the present invention adds the Mold Making in man-hour, and development process is comparatively quick and cost is low; Digital camera lens module group assembling method of the present invention adopts the fit system of latch and elongate slots to realize adjusting lens barrel displacement up and down, and structure is comparatively simple, and in addition, this assemble method reduces to cause the grey phenomenon of falling of surface in contact because of wearing and tearing.

Fig. 2 is the assembling synoptic diagram of digital camera lens module of the present invention.

[embodiment]

See also Fig. 1, digital camera lens module of the present invention comprises a lens barrel 10, a microscope base 20.

Lens barrel 10 tools one cylindrical stack shell 101, this cylindrical stack shell 101 is in order to accommodate a plurality of optical mirror slips (figure does not show), and this optical mirror slip converges the light of self imaging.Have a pin-and-hole 102 on the circumference wall of stack shell 101, it is a cylindrical hole, is generally and prevents that dust from entering, and avoids damaging a plurality of optical mirror slips in the stack shell 101 simultaneously, and this pin-and-hole 102 runs through the part wall of stack shell 101.Lens barrel 10 1 ends are openend; a plurality of eyeglasses are packed into from this end; the semiclosed end of the other end for light is entered; has a protection window 103 on this semiclosed end; it is a transparent window; not only can guarantee the light of self imaging to enter in the lens barrel 10, protect the optical mirror slip in the lens barrel 10 simultaneously, avoid dust to enter from protection window 103.

Microscope base 20 has a base 201, and this base 201 is accommodated image sensing component (figure does not show).Usually this Image Sensor is charge-coupled device (Charge Coupled Device calls CCD in the following text), perhaps complementarity matal-oxide semiconductor (Comp1ementary Metal-OxideSemiconductor calls CMOS in the following text).Extend upward a cylindrical sleeve 202 from base 201, the stack shell 101 of these sleeve 202 ccontaining lens barrels 10, stack shell 101 and sleeve 202 clearance fit, it can rotate mutually relatively.Offer elongate slots 203 on sleeve 202 walls, these elongate slots 203 Origin And Destinations have along the relative displacement of sleeve 202 axial directions.The track of this elongate slots 203 is along the upwardly extending smooth curve of sleeve 202 walls, and it makes lens barrel 10 more steady with the relative position adjustment of microscope base 20.Base 201 is fixedlyed connected with mobile phone body (figure does not show).

When lens barrel 10 and microscope base 20 assemblings, adjust focal length by latch 30.This latch 30 is a column, and the one end cooperates with pin-and-hole 102, and the other end exposes from elongate slots 203.The diameter of this latch 30 is less than the width of elongate slots 203, and it can slide along elongate slots 203.

This numerical camera mould assemble method, see also Fig. 2, lens barrel 10 is placed in the sleeve of microscope base 20, the pin-and-hole 102 of lens barrel 10 is facing to the elongate slots 203 on the microscope base 20, latch 30 inserts on the pin-and-hole 102 by elongate slots 203, latch 30 1 ends are supported in pin-and-hole 102 bottoms, and the other end exposes from elongate slots 203.When adjusting focal length, stir latch 30, because of latch 30 is limited in the elongate slots 203, so latch 30 can only slide along elongate slots 203, latch 30 is fixed with lens barrel 10 relative positions, drives lens barrel 10 simultaneously and rotates, and lens barrel 10 is motion up or down in axial direction, change the spacing of eyeglass and image sensing component, realize adjusting focal length.After being transferred to predetermined focal distance, sleeve 202 tops and with stack shell 101 contact positions, glue on the point, with the relative position of fixed lens barrel 10 and microscope base 20, after fixing, latch 30 can take off.

Be appreciated that this glue fixed form also can be on the circumference of sleeve 202 symmetry leave a plurality of holes (figure does not show), after being transferred to predetermined focal distance, in these a plurality of Kong Shangdian gluings, with fixed lens barrel 10 and microscope base 20.

Be appreciated that the track of offering elongate slots 203 on sleeve 202 walls can be Else Rule or irregular curve shape, as long as the starting point and the terminal point of this curve shape axially have relative displacement along stack shell 101.

Be appreciated that digital camera lens module of the present invention and assemble method thereof also can be applicable in the portable electron devices such as projector, video camera.
