4), mill rotational time is 30min, and rotating speed is 35 turns/min；
5), stop buffing machine, complete polishing process.
Therefore, using the technical scheme of the embodiment of the present invention, have the advantages that：The hairbrush that the present invention is adopted is adopted
The structure mixed with cashmere and collodion silk, the cashmere that diameter is big and length is short is used to be polished face glass, and diameter is little and long
The long collodion silk of degree is used to repair the face glass after polishing, and cashmere and collodion silk replace contact and grind with face glass respectively
Mill, repeats polishing and repair action so that face glass completes polishing process, and the hairbrush provided using the present invention improves glass
The optical flat effect of panel, yield can reach 99%, substantially increase the optical flat processing yield of face glass, considerably reduces and adds
Work cost.
Description of the drawings
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to present invention enforcement
Example or the accompanying drawing to be used needed for description of the prior art are briefly described.It should be evident that drawings in the following description are only
Only it is a part of embodiment of the present invention, for those of ordinary skill in the art, in the premise for not paying creative work
Under, can be with according to these other accompanying drawings of accompanying drawings acquisition.
Fig. 1 is that the embodiment of the present invention polishes hair brush structure schematic diagram；
Fig. 2 is embodiment of the present invention finishing method FB(flow block).
Specific embodiment
Describe the polishing hairbrush of the face glass of embodiment of the present invention in detail below with reference to the accompanying drawings.Additionally, in accompanying drawing
Explanation in, to essentially identical configuration or parts mark identical label, it is appropriate sometimes omit that a part repeats say
Bright and part known in those skilled in the art or structure.Although in addition, retouching to the present invention with reference to specific embodiment
State, it will be appreciated that, the description is not intended as limiting the invention to described embodiment.Conversely, the description is intended to cover
Cover replacement, improvement and the equivalent that may include in the spirit and scope of the present invention being defined by the appended claims.This
Field it is to be understood by the skilled artisans that realize that the present invention is not required for all these part, and can be without departing from this
Any change is made to the type and arrangement of these parts under bright spirit and scope.
As shown in figure 1, the invention discloses a kind of photographic head face glass polishing hairbrush, including bristle and for fixing
State the discoid mill 10 of bristle.Bristle includes cashmere 21 and collodion silk 22, and the cashmere 21 and collodion silk 22 are divided into four
Region is disposed on the mill 10.Length 3～the 10mm shorter than the length of the collodion silk 22 of wherein described cashmere 21, institute
State a diameter of described collodion silk 22 of cashmere 21 5～10 times of diameter.Four be divided in the cashmere 21 and collodion silk 22
The liquid outlet 23 of sprinkling polishing fluid is provided with region.
With reference to above-mentioned polishing hairbrush, as shown in Fig. 2 the present invention also provides a kind of photographic head face glass finishing method, bag
Include following steps：
1), photographic head face glass is fixed on polishing clamp, and is placed on polishing machine base；
2) buffing machine, mill sprinkling polishing fluid, are opened, and is pressed on polishing clamp；Because collodion silk length is more than cashmere
Length so that mill is depressed into the dynamics hinge structure of face glass and substantially increases, after pushing, for repair glue
The end bending of silk, the end of collodion silk is parallel with the end of cashmere, and contacts with photographic head face glass；
3), mill rotational time is 30min, and rotating speed is 35 turns/min；Mill rotational time extends relative to prior art
20%, rotating cycle reaches 1000 turns, and mill rotation is turned around, and face glass completes four polishings and repair action, rotation
1000 turns then complete 4000 polishings and repair action, coordinate with said brush, improve face glass acceptance rate；
4), stop buffing machine, complete polishing process；
5) face glass after polishing, is removed, outward appearance and optical flat detection is carried out.
In steps of 5
Outward appearance detection refers to that the outer surface of range estimation face glass, with the presence or absence of scratch or crackle, if any being then defective products, is needed
Again polishing or calcellation is processed.
Optical flat refers to the right cylindrical with two (or one) optical measurement planes or rectangular gauge, refers specifically to glass
Glass surface roughness value and flatness.The all minimum glass planar of surface roughness value and flatness error, can produce
Interference fringe, optical flat detection is the detection method that glass planar degree error is measured using optical interference phenomenon, is also called flat
Brilliant interferometric method.When optical flat is detected, optical flat is placed on measured surface, and the wedge angle of a very little is formed with measured surface, with list
Color light source can produce interference fringe when irradiating.The position of interference fringe is relevant with the angle of incidence of light.As incident ray perpendicular to
Gap very little between measured surface, and optical flat and measured surface, the then light for being reflected by optical flat measuring surface P reflects with measured surface
Light interfere in measuring surface P and bright or dark interference fringe occur.If under white light, there is Color Interfering Fringes By Use.
As interference fringe is straight, it is parallel to each other, and is evenly distributed, then it represents that the flatness of measured surface is fine；As interference fringe bends,
Then represent that flatness is bad.Its error amount is f=(v/ ω) × (λ/2), and λ is optical wavelength, and the mean wavelength of white light is 0.58 μ
M, ν are interference fringe amount of bow, and ω is interorder distance.The flatness error of optical measurement plane is：1 class precision for 0.03～
0.05 micron；2 class precisions for 0.1 micron.Present invention polishing hairbrush is used for the polishing of the face glass of photographic head, in step
Optical flat accuracy of detection in rapid 5 is 2 class precisions.
