Description
[technical field]
The invention relates to a kind of camera lens module fixed sturcture and method that is applied on various cameras or the optical instrument.
[background technology]
At present, the camera lens module fixed sturcture that industry is applied on camera or the optical instrument mainly contains glue-dispensing fixing structure 10, see also Fig. 1 and Fig. 2, this structure comprises a camera lens module 11 and lens mount 12, camera lens module 11 is made up of with some lens 112 lens barrel 111, at lens barrel 111 outer walls and lens mount 12 inwalls screw thread is arranged,, fix with lens mount 12 upper end junction point glue at the lens barrel 111 of camera lens module 11 then by the camera lens module 11 that is threaded.The method be earlier with the camera lens module by being threaded in the lens mount, and by the threaded adjusting optical effect, when optical effect was best, the joint point glue at lens mount 12 upper ends and lens barrel 111 fixed then.But following problem can appear in adopting said method: if use UV glue (ultraviolet glue, be ultraviolet glue) at joint point glue, then ultraviolet light can't expose in lens barrel and the lens mount seam, can not make UV glue (ultraviolet glue, be ultraviolet glue) full solidification, so that can not reach the fixed effect of anticipation; If use heat-curable glue, the situation of the position changing of the relative positions of also can focusing during heating, and camera lens module position correction is not easy to realize after solidifying, and causes product volume to give birth to and falls, manufacturing cost increases.
In view of the above shortcoming of prior art, provide a kind of stationkeeping accurate, bonding strength is better, and camera lens module fixed sturcture applied widely and method real be necessity.
[summary of the invention]
The object of the present invention is to provide a kind of stationkeeping accurate, camera lens module fixed sturcture simple in structure.
The object of the present invention is to provide a kind of stationkeeping accurate, bonding strength is camera lens module fixing means preferably.
Camera lens module fixed sturcture of the present invention comprises camera lens module and lens mount, wherein the camera lens module is made of a lens barrel and some lens etc., attacked screw thread respectively at lens barrel outer wall and lens mount inwall, there is an annular point glue groove lens barrel outer wall upper end with the screw thread connecting place, on the wall of lens mount and lens barrel joint, have several holes in addition, be used for pre-aligned.The lens barrel outer wall is concaved with annular point glue groove, and annular point glue groove is positioned at the junction of lens mount and lens barrel.
Camera lens module fixing means of the present invention may further comprise the steps: in the lens mount of at first the camera lens module being packed into, then by the UV glue (ultravioletglue of the several holes on the lens mount circumferential wall, be ultraviolet glue) with camera lens module predetermined fixed on lens mount, at last in the annular point glue groove of lens mount upper end and lens barrel joint, add to solidify glue and add the whole circle of hotwork and fix.
The invention has the beneficial effects as follows: camera lens module fixed sturcture of the present invention, by perforate on the circumferential wall of lens mount, to do pre-alignedly, the focusing position changing of the relative positions that can avoid prior art to take place, and simple in structure realizes easily.Camera lens module fixing means of the present invention is compared with existing camera lens module fixing means, used UV glue (ultraviolet glue, be ultraviolet glue) make pre-determined bit, guaranteed the accurately fixing of focusing position, and owing on the circumferential wall of lens mount, have the hole, make ultraviolet luminous energy fully shine UV glue (ultravioletglue, i.e. ultraviolet glue).

[embodiment]
Please refer to Fig. 3, Fig. 4 and Fig. 5, camera lens module fixed sturcture 20 of the present invention comprises camera lens module 21 and lens mount 22, wherein camera lens module 21 is made of a lens barrel 211 and some lens 212 etc., lens mount 22 comprises a circumferential wall (not indicating), attack the screw thread (indicating) of certain-length respectively at lens barrel 211 outer walls and lens mount 22 inwalls, and have annular point glue groove 213 at lens barrel 211 outer walls, this annular point glue groove 213 mainly is to be used for doing at last holding when heat curing is handled heat-curable glue, make heat-curable glue can fully contact lens barrel 211 and lens mount 22, thereby reach adhesive effect preferably, in addition on lens mount 22 and circumferential wall that lens barrel 211 engages, offer several holes 221, be generally 4, and be symmetrically distributed on the circumferential wall of lens mount 22, be mainly used in UV glue (ultraviolet glue, be ultraviolet glue) do can allow ultraviolet light fully shine when pre-aligned, thus reach UV glue (ultraviolet glue, i.e. ultraviolet glue) full solidification.
Camera lens module fixing means of the present invention may further comprise the steps: at first with lens barrel 211 by being threaded into predetermined lengths in the lens mount 22, so that camera lens module optical effect the best, coat UV glue (ultraviolet glue in the several holes 221 on lens mount 22 circumferential wall again, be ultraviolet glue), use UV-irradiation then, make UV glue (ultraviolet glue, be ultraviolet glue) full solidification, thereby it is camera lens module 21 predetermined fixed are on lens mount 22, last fixing with the whole circle of heat-curable glue work in the some glue groove 213 of lens mount 22 upper ends and lens barrel 211 joints.
Obviously, camera lens module fixed sturcture of the present invention is by offering hole 221 on the perisporium of lens mount, do with UV glue (ultraviolet glue, i.e. ultraviolet glue) pre-aligned, the focusing position changing of the relative positions that can avoid prior art to take place, and simple in structure, realize easily.Camera lens module fixing means of the present invention is compared with existing camera lens module fixing means, and the focusing stationkeeping is accurate, and bonding strength is good, thereby has improved product quality.
Be appreciated that lens barrel 211 outer walls of camera lens module fixed sturcture 20 of the present invention and the screw thread of lens mount 22 inwalls can save, the camera lens module utilizes UV glue (ultraviolet glue, i.e. ultraviolet glue) and heat-curable glue to fix fully.
In addition, the annular point glue groove 213 on the lens barrel 211 of camera lens module fixed sturcture 20 of the present invention also can save, and directly makes whole circle and fix at lens barrel 211 and the lens mount 22 connecting places glue that is heating and curing.
