[embodiment]
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Referring to Fig. 1 to Fig. 3, the attachment force detection method of the filter in lens module that embodiments of the invention provide comprises the steps:
(1) as shown in Figure 1, provide a camera lens module 10, it comprises lens assembly 20, optical filter 30 and lens barrel 40.Above-mentioned lens assembly 20 and optical filter 30 extremely are housed in the lens barrel 40 as side successively from the thing side.
Described lens assembly 20 can comprise various optical elements such as lens 22,24 and interval body 26.These lens 22 and 24 material can be glass or plastic cement.These lens 22 and 24 peripheral circumferential surface are fixed in the lens barrel 40 by viscose glue.This interval body 26 ringwise, it is used between lens 24 and optical filter 30 forming at interval, causes component wear to avoid the two because of contact or collision.The peripheral circumferential surface of this interval body 26 is glued together fixing with the madial wall of lens barrel 40 via viscose glue.Preferably, this lens assembly 20 also comprises iris diaphragm plate 28, and this iris diaphragm plate 28 can be located between lens 22 and 24.
Described optical filter 30 is contained in the lens barrel 40, and adjacent with interval body 26.This optical filter 30 and interval body 26 are by viscose glue and glued together.
Described lens barrel 40 can be divided into lens barrel front end 42 and lens barrel rear end 44.Described lens barrel front end 42 is positioned at the thing side of camera lens module 10, and these lens barrel front end 42 inside contain described lens 22,24.Described lens barrel rear end 44 is positioned at the picture side of camera lens module 10, and these 44 inside, lens barrel rear end contain described interval body 26 and optical filter 30.The outside of this lens barrel rear end 44 is provided with external thread.
(2) as shown in Figure 2, remove camera lens front end 42 and also remove the lens 22,24 that are arranged in this lens barrel front end 42, to expose interval body 26 and this optical filter 30 adjacent with optical filter 30.This process can adopt methods such as electric spark cutting, cut or cutting knife cutting, and camera lens module 10 is cut.In the present embodiment, this process adopts cutting knife that camera lens module 10 is cut, and removing camera lens front end 42 and to remove the lens 22,24 that are arranged in this lens barrel front end 42, thereby exposes interval body 26 and this optical filter 30 adjacent with optical filter 30.
(3) as shown in Figure 3,, optical filter 30 is pushed away and the reading of record optical filter 30 pressure gauge 50 when being pushed from interval body 26 from being positioned at interval body 26 1 side direction optical filters 30 application of forces with pressure gauge 50.These concrete steps can be:
With the measuring head 52 of pressure gauge 50 the surface that interval body 26 1 sides support optical filter 30 that is positioned at, and optical filter 30 is exerted pressure, so that optical filter 30 comes off from interval body 26 along direction shown in the arrow among Fig. 3 from optical filter 30.Treat that optical filter 30 writes down the reading of pressure gauge 50 when interval body 26 comes off, can obtain the adhesion of optical filter 30.Described pressure gauge 50 can be mechanical gauge or electronic pressure meter.
Usually, carry out described optical filter is pushed away the step that falls with pressure gauge from interval body before, the lens barrel rear end 44 that contains interval body 26 and optical filter 30 is fixing.Present embodiment is fixing with lens barrel rear end 44 by stationary installation 60.Preferably, be formed with the internal thread that matches with the external thread of lens barrel rear end 44 on this stationary installation 60 and the surface that lens barrel rear end 44 contacts, this stationary installation 60 can be fixing with described lens barrel rear end 44 by the engagement of screw thread.
As shown in Figure 4, preferably, after executing the above-mentioned step that camera lens rear end 44 is fixed, also can adopt bayonet unit 70 that interval body 26 and stationary installation 60 are fastened togather, to prevent that interval body 26 together comes off with optical filter 30 in optical filter 30 application of force processes from lens barrel rear end 44.
The attachment force detection method of the filter in lens module that present embodiment provides, by pressure gauge 50 optical filter 30 is pushed away from interval body 26 surfaces, and the reading of record optical filter 30 pressure gauge 50 when being pushed, thereby record the adhesion of optical filter 30 in the camera lens module 10.Characteristics such as the attachment force detection method of this filter in lens module can have simply, and is quick, it is used in the process of a large amount of production camera lens modules the camera lens module is surveyed sample, thereby guarantees the quality of camera lens module.
In addition, those skilled in the art also can do other and change in spirit of the present invention, as the cutting method of the saturating module of proper transformation mirror, the order of proper transformation operation steps etc., as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
