Description
Technical field
The present invention relates to optical field, more particularly to a kind of non-spherical lens component.
Background technology
In optical communication industry, as welding needs, Conventional glass camera lens directly cannot be welded in 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 lens to be bondd with lens barrel using glue, but due to the metal material behavior different from the two of glass kinds, causes a little
It is gluing connect after lens and the cohesive force between lens barrel be unable to reach very good situation, cause under some adverse circumstances use
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 so as to cannot 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 uncontrollable bubble-tight problem, and pressure ring, and trim ring exists
The risk of deformation is there may be after long-time use, is caused lens to produce in lens barrel eccentric, is affected the matter of whole light path system
Amount.
The content of the invention
It is an object of the invention to provide a kind of non-spherical lens component with bimirror cylinder.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of non-spherical lens component, including outer lens barrel, fixation
Inner lens cone, the non-spherical lens being fixed in the inner lens cone in the outer lens barrel, the outer lens barrel are round table-like structure,
Offer inside which for housing the first containing cavity of inner lens cone, the inwall of first containing cavity is provided with a circle excessive glue groove, institute
Outer lens barrel is stated for stainless steel, the inner lens cone has a stainless steel of Gold plated Layer for surface, the outer lens barrel with it is described
Gluing is carried out using method for dispensing glue between inner lens cone, the inner lens cone is cylindric, is offered for housing aspheric inside which
Second containing cavity of face lens, the non-spherical lens are glass material, are led between the inner lens cone and the non-spherical lens
The mode for crossing die casting is fixed.
Further, the bottom of first containing cavity offers light hole.
Further, diameter of the diameter of the light hole less than first containing cavity.
Further, the light hole forms the spacing of internal lens barrel axial limiting with the junction of first containing cavity
Face.
Compared with prior art, the beneficial effect of non-spherical lens component of the present invention is：By inner lens cone and aspherical mirror
The pressure casting method of head, substantially increases firmness glued between aspheric lens and inner lens cone, and due to being interference fit,
Substantially reduce the tolerance and the air-tightness that effectively can be guaranteed between inner lens cone and aspheric lens of bias.By to scope
The gold-plated process of cylinder, avoids rustless steel evolution reaction at high temperature well, and outermost outer lens barrel due to scope
Cylinder is not used in through pyroreaction, therefore can be also effectively maintained the excellent weldering of outer lens barrel itself using the method for point glue glued adhesion
Connect performance.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
Refer to Fig. 1, a kind of non-spherical lens component, including it is outer lens barrel 3, the inner lens cone 2 being fixed in outer lens barrel 3, solid
The non-spherical lens 1 being scheduled in inner lens cone 3, outer lens barrel 3 are round table-like structure, are offered for housing inner lens cone 2 inside which
First containing cavity 31, the bottom of the first containing cavity 31 offer light hole 32, and the diameter of light hole 32 is less than the first containing cavity 31
Diameter, the junction of light hole 32 and the first containing cavity 31 forms the confined planes 33 to 2 axial limiting of inner lens cone, 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 in the lens barrel eccentric, affect 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 offered inside which for housing the second containing cavity 21 of non-spherical lens 1, aspheric surface for cylindric
Lens 1 are glass material, are fixed between inner lens cone 2 and non-spherical lens 1 by way of die casting, 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 under high temperature after molding
Bigger inner lens cone can be retracted firmly to block after cooling, 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.Simultaneously inner lens cone surface is carried out gold-plated
Process also can avoid general stainless steel material to cause mirror in the chemical reaction such as generation inner element precipitation after high temperature well
The outside discoloration of cylinder and impact material welding performance.
Pressure casting method of the present invention by inner lens cone and aspheric lens, substantially increase aspheric lens and inner lens cone it
Between glued firmness, and due to being interference fit, substantially reduce the tolerance of bias and can effectively guarantee inner lens cone
Air-tightness between aspheric lens.By the gold-plated process to inner lens cone, rustless steel is avoided well at high temperature
Evolution reaction, and outermost outer lens barrel, is not used in through pyroreaction using the method for a glue glued adhesion due to inner lens cone, because
This can also be effectively maintained the excellent welding performance of outer lens barrel itself.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, some deformations and improvement can also be made, these belong to the protection model of the present invention
Enclose.
