Description
Technical field
The present invention relates to a kind of device and method of disassembling lens module, relate in particular to a kind of device and method that in disassembling process, can prevent to damage the disassembling lens module of optical element.
Background technology
Common camera lens module generally includes optical elements such as some eyeglasses of being contained in the lens barrel, iris diaphragm plate, optical filter, and the interval body etc. that is used to control various optical element spacings.In the assembling process of this kind camera lens module, optical elements such as said lens, iris diaphragm plate, optical filter are contained in the lens barrel successively, the lens that optical filter is adjacent separate through interval body.Optical filter is glued together by gluing process and interval body.
When eyeglass, iris diaphragm plate, optical filter etc. are assembled into lens barrel; Because personal error and vibration in use are easy to cause the camera lens module to lose efficacy, thereby camera lens module that need these are bad is disassembled to analyze the inefficacy which kind of reason causes the camera lens module again.
In the prior art, a kind of method of disassembling lens module is oppressed eyeglass, iris diaphragm plate etc. for a club is stretched in the lens barrel, itself and lens barrel are separated; Another kind method is for to be placed on the camera lens module on the air cushion bed, and the pressure head of air cushion bed is done down under air pressure control and with compressing eyeglass, iris diaphragm plate etc. it separated towards motion with lens barrel.Adopt above-mentioned two kinds of methods can the disassembling lens module, but infringement eyeglass, iris diaphragm plate, optical filter etc. easily, thus can not correct analysis camera lens module failure reasons.
Summary of the invention
In view of this, provide a kind of device and method of the disassembling lens module that in disassembling process, can prevent to damage optical element real for necessary.
A kind of device of disassembling lens module; Said camera lens module comprises lens barrel and is contained in the optical element in the said lens barrel; Said device comprises at least one cutting knife, is used for mobile and fixes the control device of said at least one cutting knife, the stationary installation and the whirligig of fixing said camera lens module; Said whirligig can drive that the camera lens module that is fixed on the said stationary installation rotates and axial displacement take place simultaneously rotating; The rotation direction that the blade of said at least one cutting knife rotates relative to said camera lens module towards said at least one cutting knife; When said camera lens module rotated, said at least one cutting knife stretched in the said lens barrel and along said lens barrel inwall said lens barrel is separated with said optical element.
A kind of method of disassembling lens module, said camera lens module comprise lens barrel and are contained in the optical element in the said lens barrel that the method for said disassembling lens module may further comprise the steps:
The device of one disassembling lens module is provided, and said device comprises the stationary installation and the whirligig of cutting knife, fixing said camera lens module;
The camera lens module is fixed on the stationary installation;
Cutting knife is stretched in the lens barrel and is close to the lens barrel inwall;
Keep cutting knife motionless, open whirligig and drive the stationary installation rotation, make cutting knife lens barrel separated with optical element along the lens barrel inwall.
Compared with prior art, the cutting knife of said disassembling apparatus of present embodiment and method is separated optical element and lens barrel along the lens barrel inwall, therefore, can keep the integrality of optical element, and optical element can not suffer damage.
Description of drawings
Fig. 1 is the schematic representation of apparatus of embodiment of the invention disassembling lens module.
Embodiment
As shown in Figure 1, the device of the disassembling lens module 10 that the embodiment of the invention provides comprises stationary installation 20, whirligig 30, cutting knife 40, gathering-device 50 and control device 60.
Whirligig 30 can drive stationary installation 20 and rotate rising or decline, thereby makes the camera lens module 10 that is fixed in the containing hole 21 rotate rising or decline, and this whirligig 30 can be by motor driven.Whirligig 30 has a through hole 32, and the diameter of through hole 32 is more than or equal to the internal diameter of lens barrel 11.
The blade of cutting knife 40 is towards the sense of rotation of camera lens module 10, and cutting knife 40 stretches in the lens barrel 11 eyeglass 12, interval body 13 and optical filter 14 are separated with lens barrel 11.Cutting knife 40 is fixed on above the control device 60, and control device 60 can make the motion of cutting knife 40 upper and lower, left and right, and fixed cutting tool 40 keeps fixing then.
In the present embodiment, cutting knife 40 is two, and during operative installations disassembling lens module 10, the distance between the cutting knife 40 is less than the internal diameter of lens barrel 11 and greater than the size of optic 121, so that cutting knife 40 can not destroy optic 121.
Certainly, cutting knife 40 also can be one, also can be more than or equal to three.When the quantity of cutting knife 40 more than or equal to three the time, during operative installations disassembling lens module 10, cutting knife 40 is positioned on the same circumference, and the diameter of circumference is less than the internal diameter of lens barrel 11 and greater than the size of optic 121.
Gathering-device 50 is used for collecting eyeglass 12, interval body 13 and the optical filter 14 that separates with lens barrel 11.Eyeglass 12 after the separation, interval body 13 and optical filter 14 fall in the gathering-device 50 through through hole 32.Gathering-device 50 can be funnel, pallet etc.
When use device disassembling lens module 10; Camera lens module 10 is fixed in the containing hole 21 of stationary installation 20; Control device 60 moves cutting knife 40, makes cutting knife 40 be close to lens barrel 11 inwalls and stretches in the lens barrel 11, keeps cutting knife 40 motionless, startup whirligigs 30; Stationary installation 20 is being rotated under the drive of whirligig 30 and is being risen; The length that makes cutting knife 40 stretch into lens barrel 11 changes, and along with cutting knife 40 stretches into the continuous variation of length in the lens barrel 11, eyeglass 12, interval body 12, optical filter 14 separate with lens barrel 11.
Because cutting knife 40 is separated eyeglass 12, interval body 13 and optical filter 14 along lens barrel 11 inwalls with lens barrel 11, therefore, eyeglass 12, interval body 13 and optical filter 14 are kept perfectly, can suffer damage, and making can correct analysis camera lens module failure reasons.
It is understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion, and all these changes and distortion all should belong to the protection domain of claim of the present invention according to technical scheme of the present invention and technical conceive.
