Description
Technical field
The present invention relates to Gap theory field, more particularly to a kind of portable spectrometer slit and preparation method thereof.
Background technology
Slit is one of core component of spectrometer.It is a variable-width, the slot apertures of narrow elongate.There is fixed slit,
Unilateral adjustable asymmetric slit and bilateral adjustable symmetrical slots.Spectrometer be widely used in the structure of material and into
The field such as point measure and analyze, there is analysis precision height, measurement range is big, speed is accordingly fast, be mainly used in
In the research field of the subjects such as medicine, chemistry, geology, physics.The continuous development of optical technology promotes spectrometer in recent years
Require to further improve in low cost and micromation etc., thus low cost, quickly, simply to produce high-precision optical narrow
The method of seam, has major economic value and social effect.
Common slit production method mainly has on the market at present：
First, simple processing
Wire cutting：The slit of such a technique processing, slit periphery has some defects.Since wire cutting can produce some oil
, it is necessary to which the later stage clears up, cleaning is clean for dirts etc..In addition, wire cutting directly influences the vertical edges of slit due to the speed of silk
Straightness, and for the processing of some ultra-thin materials, it is unsuitable.The gap width of linear cutter is generally all in 0.2mm
More than, it cannot be met the requirements for high-accuracy slit.
2nd, laser machine
It is faster than the efficiency of wire cutting to laser machine slit.But there is also some shortcomings of cutting processing, such as：Lower knife and
Return sword mouth seamed edge processing.Since laser is by high temperature burning and cutting material, easily residue, residue are retained on the periphery of slit
Color be all black, and be difficult to clean up.The minimum seam of Laser Processing can reach 0.1mm, or even the seam of smaller.But
It is that after N times of amplification, the presence of ripple glaze is the defects of it is maximum.In addition, Laser Processing slit changes material easily by high temperature
Property, for the material of some special materials, easily have an impact.
3rd, etching and processing
Application is few at present for etching and processing slit, and etching and processing slit is the material using metal materials such as stainless steel, copper as raw material
Material thickness also limit the minimum gap that this technique can process.The material of 0.03mm thickness is used at present, and processing 0.05mm is most
Small gap.If slit width increases, material thickness range of choice bigger can be used.Such as：Process the seam of 0.2mm, then
Material thickness can be used from 0.03 to 0.1mm.Processing slit precision reaches as high as ± 0.005mm.
4th, electron beam process
The great advantage of electron beam process is can to process extremely narrow slit, and the material of processing also has a variety of, metal and non-
Metal is all feasible.But the difficulty of electron beam process is at a relatively high, and cost is higher by many times than first three significantly, cost performance
It is very low.Since the machinable slit of this technique can reach several microns, the scope of application is also smaller, primarily directed to high-end market
Product and use.
From the above it can be seen that current slit processing technology is relative complex, cost is higher.For producing spectrometer, life can be increased
Produce cost and manufacture difficulty；And the excellent precision for determining spectrometer that slit makes, thus low cost, precision are high, make
Simple slit production method is always what people were badly in need of.
The content of the invention
The present invention overcomes above-mentioned the deficiencies in the prior art, there is provided a kind of portable spectrometer slit and its making side
Method.The present invention by the fixation of left slit blade and right slit blade and wire, left slit blade and right slit blade it
Between form slit, it is not necessary to adjust, the width of slit is determined by the diameter of wire.
Technical scheme：
A kind of portable spectrometer slit, including slit base, slit pressing plate, left slit blade, right slit blade, support
Ring and wire；The slit base lower end is fixedly connected with support ring, and technology groove, the work are machined with the slit base
Skill slot bottom end is machined with two through holes, and wire is provided with the through hole, through the through hole and is located at the slit base
The wire both sides of top are respectively arranged with left slit blade and right slit blade, the left slit blade and the right slit knife
Piece is Nian Jie with the slit base respectively, and the slit base is fixedly connected by four clamping bolts with slit pressing plate, described
Slit loophole is machined with respectively in slit base, the slit pressing plate and the support ring.
Further, the slit base, the slit pressing plate are identical with the slit printing opacity pore size in the support ring,
And slit loophole is coaxially disposed described in three groups.
A kind of its production method of portable spectrometer slit, this method comprises the following steps：
Step a：The making of slit blade：By Double-shaver blade therefrom between be divided into two groups of symmetrical slit blades, i.e.,
Left slit blade and right slit blade；
Step b：The selection of slit width：Wire is selected according to the demand of slit width, wire diameter is slit
Width；
Step c：The making of slit：By selected wire through the through hole on slit base, and in wire both sides point
Left and right slit blade is not placed, is made blade cutting edge side close from wire both sides and is kept contacting with tinsel, is formed narrow
Seam；
Step d：The fixation of slit blade：Snearing in the lower section of left and right slit blade smears instant glue, will be left and right narrow
Seam blade position is fixed；
Step e：Concealed metal silk：It is buried in by wire bending unnecessary on slit blade, and by the wire of bending
In technology groove；
Step f：Fixed slit blade：Slit blade is fixed on slit base by slit pressing plate and clamping bolt.
Further, the slit wire in the step e after bending is in same level with left and right slit blade.
The present invention has the advantages that relative to the prior art：
Production method of the present invention is simple, cost is low, the precision of slit is high, while it also avoid traditional slit Width adjusting mechanism and hold
Deviation easily occurs, influences slit quality.And by the fixation of double-edged razor blade and wire, slit is formed between double-edged razor blade,
It need not adjust, the width of slit is determined by wire diameter.
The slit production method of the present invention, slit is formed by left slit blade and right slit blade, by the diameter of wire
Limit, the width slit different with length can be produced according to the actual requirements, there is precision height, cost is low, making is simple
It is convenient to wait significant advantage.
The blade that the present invention forms used in slit can select common stainless steel double-sided razor blade, and cost is low, is easy to
Buying.The liquid glue suitable for quick-binding between metal may be selected in rapid hardening liquid glue.
