Description
Technical field
The utility model is related to optical field, more particularly to a kind of non-spherical lens component.
Background technology
In optical communication industry, because welding needs, Conventional glass camera lens cannot be directly welded into whole optical system,
Would generally be using being welded after overcoat metal lens barrel.Assembling mode between traditional lens barrel and camera lens is generally divided into two kinds：One
It is that lens are bonded with lens barrel using glue, but due to metal and two kinds of different material properties of glass, causes a little
The cohesive force between lens and lens barrel after glue sticking is unable to reach very good situation, causes to be used under some adverse circumstances
When be susceptible to the phenomenon that lens come off, while still can there is the sky of any between the lens and lens barrel of the gluing knot of point of use
Gap, is that gap coordinates, and causes the increasing of its overall light path bias tolerance, simultaneously because the presence in gap, makes it to be applied to
Some have on the product of particular/special requirement for air-tightness.Second assembling mode is to use pressure ring, the side of the machinery positioning such as trim ring
Method, lens are fixed in lens barrel, but the method equally exists the problem of uncontrollable air-tightness, and pressure ring, and trim ring exists
The risk of deformation is there may be after long-time use, causes lens that bias is produced in lens barrel, influence the matter of whole light path system
Amount.
Utility model content
The purpose of this utility model is to provide a kind of non-spherical lens component with bimirror cylinder.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of non-spherical lens component, including outer lens barrel,
The inner lens cone being fixed in the outer lens barrel, the non-spherical lens being fixed in the inner lens cone, the outer lens barrel are round table-like
Structure, offers the first accommodating cavity for housing inner lens cone inside it, the inwall of first accommodating cavity is provided with a circle excessive glue
Groove, the outer lens barrel is stainless steel, and the inner lens cone has the stainless steel of Gold plated Layer for surface, the outer lens barrel with
Gluing is carried out using method for dispensing glue between the inner lens cone, the inner lens cone is cylindric, is offered for housing inside it
Second accommodating cavity of non-spherical lens, the non-spherical lens be glass material, the inner lens cone and the non-spherical lens it
Between fixed by way of die casting.
Further, the bottom of first accommodating cavity offers light hole.
Further, diameter of the diameter of the light hole less than first accommodating cavity.
Further, the light hole forms the spacing of internal lens barrel axial limiting with the junction of first accommodating cavity
Face.
Compared with prior art, the beneficial effect of the utility model non-spherical lens component is：By inner lens cone and aspheric
The pressure casting method of face camera lens, substantially increases firmness glued between aspheric lens and inner lens cone, and due to being interference
Coordinate, the air-tightness that substantially reduce the tolerance of bias and can effectively ensure between inner lens cone and aspheric lens.Pass through
Gold-plated treatment to inner lens cone, avoids stainless steel evolution reaction at high temperature well, and outermost outer lens barrel due to
With inner lens cone using the method for a glue glued adhesion, it is not used in by pyroreaction, therefore it is excellent in itself to be also effectively maintained outer lens barrel
Good welding performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Refer to Fig. 1, a kind of non-spherical lens component, including outer lens barrel 3, the inner lens cone 2, solid that is fixed in outer lens barrel 3
The non-spherical lens 1 in inner lens cone 3 is scheduled on, outer lens barrel 3 is round table-like structure, is offered inside it for housing inner lens cone 2
First accommodating cavity 31, the bottom of the first accommodating cavity 31 offers light hole 32, and the diameter of light hole 32 is less than the first accommodating cavity 31
Diameter, the junction of the accommodating cavity 31 of light hole 32 and first forms the confined planes 33 to the axial limiting of inner lens cone 2, and first houses
The inwall in chamber 31 is provided with a circle excessive glue groove 34.
Outer lens barrel 3 is stainless steel, and inner lens cone 2 has the stainless steel of Gold plated Layer, outer lens barrel 3 and scope for surface
Gluing is carried out using method for dispensing glue between cylinder 2, unnecessary glue can flow into excessive glue groove, it is ensured that it is unnecessary not have between
Glue, cause lens to produce bias in lens barrel, influence the quality of whole light path system.Simultaneously between two kinds of metal materials
The glued firmness more glued than between traditional metal and glass is higher.
Inner lens cone 2 is cylindric, and the second accommodating cavity 21 for housing non-spherical lens 1 is offered inside it, aspherical
Lens 1 are glass material, are fixed by way of die casting between inner lens cone 2 and non-spherical lens 1, in press casting procedure, will be interior
Lens barrel 2 carries out die casting together with aspheric lens 1, due to the difference of thermal coefficient of expansion, the aspheric lens after being molded under high temperature
Bigger inner lens cone can be retracted after cooling firmly blocks, produce interference fit, therefore shearing force between the two can reach
To more than 600N, the shearing force of the 50N-200N of significantly larger than general gluing process.Inner lens cone surface is carried out simultaneously gold-plated
Treatment can also avoid well general stainless steel material by after high temperature produce inner element separate out etc. chemical reaction causing mirror
The outside discoloration of cylinder and influence material welding performance.
The utility model substantially increases aspheric lens and scope by inner lens cone and the pressure casting method of aspheric lens
Glued firmness between cylinder, and due to being interference fit, substantially reduce the tolerance of bias and can effectively ensure interior
Air-tightness between lens barrel and aspheric lens.By the gold-plated treatment to inner lens cone, stainless steel is avoided well in high temperature
Under evolution reaction, and outermost outer lens barrel due to inner lens cone using point glue glued adhesion method, be not used in anti-by high temperature
Should, therefore can also be effectively maintained outer lens barrel welding performance excellent in itself.
Above-described is only some implementation methods of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality
New protection domain.
