Description
Technical field
The present invention relates to field of optical lens, and specially a kind of camera lens exempts from focusing system.
Background technology
The fast development of science and technology does what the various technologies for measuring and judging were maked rapid progress using machine instead of human eye
Development, some be not suitable for manual work dangerous work environment or artificial vision be difficult to the occasion met the requirements, commonly use machine
Device vision substitutes artificial vision；Simultaneously in high-volume industrial processes, manually visual inspection product quality efficiency is low
And precision is not high, and production efficiency and the degree of automation of production can be greatly improved with machine vision detection method；And machine
Vision is easily achieved information integration, is the basic technology for realizing computer integrated manufacturing system.It can be on most fast production line to production
Product are measured, guide, detect and are identified, and the completion production task that can be guaranteed both quality and quantity；In this way to the requirement of optical lens
It is higher and higher.At present using it is more be exactly Japanese camera lens and German camera lens, but expensive, domestic camera lens is also slowly
It opens up markets, and moderate.
Focusing is named focusing, is focused on, and refers to change image distance, that is, the distance of change camera lens optical center plate plane on earth, for
For microscope, focusing is clear image in order to obtain and adjusts the distance between object lens and testee, clear to obtain this object
The adjusting process of clear picture.But many people are unfamiliar with lens focusing during actual use, are obtained it is difficult to adjust focal length
To the image being apparent from, so needing a kind of lens system for exempting from focusing.Existing production method is by lens barrel and lens mount spiral shell
Line connects, and reserves certain height, adjusts camera lens, then dispensing is fixed, and this method also needs to add lens mount and lens barrel
Work screw thread, complex procedures, processing efficiency are low.
Patent No. CN205545603U discloses one kind and exempts from focusing lens, it includes lens barrel, lens mount, eyeglass, optical filter, core
Piece；The top of lens mount is equipped with lens barrel, and lens mount is internally provided with optical filter, is filled out between optical filter and lens barrel equipped with eyeglass, filter
The bottom of mating plate is equipped with chip；It is characterized in that：The lens barrel is an integral structure with lens mount；The edge of the eyeglass
Thickness is equal to the distance between optical filter to lens barrel.Although this design reduces assembly process between microscope base and lens barrel,
Improve difficulty of processing, it is impossible to accurately control dimensional accuracy, it is impossible to meet the design of high-precision requirement.
Invention content
The problem of for background technology, the present invention provides a kind of camera lenses to exempt from focusing system, without microscope base, lens barrel
Microscope base can directly be regarded, exempt the process of focusing, exempt screw thread process, rational size design can not only meet high-precision will
It asks, improves imaging effect, and simple for process, greatly improve producing efficiency.
To achieve the above object, the present invention provides following technical solution：A kind of camera lens exempts from focusing system, includes lens barrel, mirror
Piece, diaphragm piece, infrared fileter, protective glass, the eyeglass are divided into the first eyeglass, the second eyeglass and the inside for being set on lens barrel,
Diaphragm piece is provided among first eyeglass and the second eyeglass, is provided with infrared fileter on the right side of second eyeglass, institute
It states camera lens to be directly anchored on the protective glass of chip front end, the height error of the lens barrel is less than 0.002mm, the eyeglass
The error of thickness and rise is less than 0.002mm.
As a kind of preferred technical solution of the present invention, the outer diameter of first eyeglass and the second eyeglass is 1.66mm.
As a kind of preferred technical solution of the present invention, first eyeglass, the second eyeglass and diaphragm piece arranged in co-axial alignment.
As a kind of preferred technical solution of the present invention, the lens barrel has the function of lens barrel and microscope base.
Compared with prior art, the beneficial effects of the invention are as follows：Camera lens is directly anchored to the protection glass of chip by the present invention
On glass, and the lens barrel of the present invention has the function of two kinds of lens barrel and microscope base, does not need to separately set microscope base, reduces making for number of parts
With so as to reduce cumulative errors, simplifying flow chart, while reduce the manufacture difficulty of module, the present invention is by the height of lens barrel
Control errors are spent in 0.002mm, and the thickness and chord error of eyeglass are in 0.002mm, thus by the error control of whole system
System in accurately range, it is ensured that focusing object distance, meet realize object distance in 3mm-25mm all can blur-free imaging effect.
Description of the drawings
Fig. 1 is structural profile illustration of the present invention；
In figure：1- lens barrels；The first eyeglasses of 2-；3- diaphragm pieces；The second eyeglasses of 4-；5- infrared fileters；6- protective glass.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
