Part, light efficiency booster, uniform illumination device, light-beam shaper, On Microoptical Scanner, colored filter, even optical anti-counterfeiting mark
Will.Especially because micro-lens array film flexible can be made in it, more cause widely to pay attention to.In recent years, it is developed
A variety of manufacturing technologies, but more complicated fine processing technique is all used, equipment is more complicated, and production process is also relatively more multiple
Miscellaneous, higher cost, process flow is longer.
Summary of the invention
Present invention defect of the existing technology；A kind of manufacture craft of micro-lens array is provided, the technology utilization
Precise laser drilling technology makes micro-lens array, which can simplify technique, reduces cost, shortens production stream
Journey.
To achieve the above object, the present invention provides a kind of manufacture crafts of micro-lens array, comprising the following steps:
1) then being refined stainless base steel version and being polished on one side carries out the greasy dirt that cleaning removes surface, drying；
2) stainless base steel version is placed on the workbench of precise laser drilling machine, is arranged according to the size and matrix of miniature circular hole
The size of column requires to carry out accurate punching；Obtain the stainless base steel version with miniature array of circular apertures；
3) after being cleaned and dried the stainless base steel version with miniature array of circular apertures, on its surface, coating a thin layer is ultraviolet
(UV) solidification glue；
4) the stainless base steel version for having been coated with uv-curable glue is placed in vacuum chamber, is vacuumized；So that miniature circular hole
Intracavitary air discharge, and uv-curable glue is made to be completely filled with the intracavitary of miniature circular hole；
5) then the stainless base steel version with micro- shape array of circular apertures is placed on centrifugation photoresist spinner get rid of it is extra ultraviolet solid
Change glue (under the synergy of the centrifugal force of the surface tension and photoresist spinner of uv-curable glue, the intracavitary purple in each miniature circular hole
The liquid level of outer solidification glue will become the spherical surface with certain curvature radius), then with ultraviolet light irradiation, make its solidification, just at
The spherical surface of micro lens；Obtain micro-lens array.
Further, in the step 2), diameter and the depth ratio of miniature circular hole are 1:1~3.
Still further, the diameter and depth ratio of the miniature circular hole are 1:1.
The beneficial effects of the present invention are:
Technique of the invention is convenient for massive duplication, this is had the micro-lens array of the uv-curable glue after solidifying not
Base steel version of becoming rusty carries out electroforming duplication, so that it may obtain the nickel plate of convex or recessed micro-lens array.Due to nickel plate machine with higher
Tool intensity, so that it may replicate in large quantity, produce micro-lens array.

Specific embodiment
In order to better explain the present invention, below in conjunction with the specific embodiment main contents that the present invention is furture elucidated, but
The contents of the present invention are not limited solely to following embodiment.The manufacture craft of micro-lens array, comprising the following steps:
1) it by being refined and being polished on one side with a thickness of 3~4 millimeters of stainless base steel version, is then carefully cleaned,
To remove the greasy dirt on surface, and use hot blast drying；
2) cleaned stainless base steel version is placed on the workbench of precise laser drilling machine, as shown in Figure 1: according to
The size of miniature circular hole and the size of matrix arrangement require to carry out accurate punching, and diameter and the depth ratio of miniature circular hole reach 1:1；?
The array of miniature circular hole is got in stainless base steel version, and (miniature Circularhole diameter size shown in FIG. 1 and array layout are only one by one
Example, can set different Circularhole diameter and array layout according to the requirement of actual use.)；Wherein, precise laser drilling machine
Running parameter are as follows:
Laser power: 200W
Wavelength: 1064NM
Pulse width: 0.1~20ms；
The size of miniature circular hole and the size of matrix arrangement depending on require and machining accuracy depending on, generally 0.001~
0.1mm；
3) the stainless base steel version for having accomplished fluently miniature array of circular apertures is subjected to depth cleaning, except the ash in degreasing and micropore
Slag, and dried up with drying nitrogen；
4) a thin layer ultraviolet (UV) solidification is coated in stainless base steel version after cleaning up, with miniature array of circular apertures
Glue；
5) the stainless base steel version for having been coated with uv-curable glue is placed in vacuum chamber, is vacuumized, so that miniature circular hole
Intracavitary air discharge, and uv-curable glue is made to be completely filled with the intracavitary of miniature circular hole；
6) stainless steel substrate 2 for after vacuumize process, being coated with uv-curable glue 1 is installed on high speed photoresist spinner, it will
Extra uv-curable glue is got rid of, the intracorporal uv-curable glue of chamber of each circle micropore its surface tension and photoresist spinner from
Under the synergy of mental and physical efforts, a spherical surface (Fig. 2) just will form,；It then, with wavelength is immediately the ultraviolet light irradiation of 365nm, it will
Ultra-violet curing adhesive curing, the spherical surface that uv-curable glue is formed in miniature circular hole is exactly the spherical surface of micro lens, and each miniature circular hole
Middle uv-curable glue is formed by the array of spherical surface to get namely micro-lens array is arrived.The radius of curvature R of this spherical surface depends on
In the revolving speed of photoresist spinner and the viscosity of uv-curable glue, so, it, can by adjusting the viscosity of photoresist spinner revolving speed and uv-curable glue
To obtain the spherical surface of different curvature radius.
In mass production, since the mechanical strength of uv-curable glue is not too much high, such template can only be lacked
The duplication of amount.It, just need to be by the stainless of the micro-lens array formed with uv-curable glue in order to can be carried out large batch of duplication
Base steel version carries out electroforming duplication, can thus obtain the nickel template of convex or recessed micro-lens array, micro-lens array
Nickel template just can be used for producing large batch of micro-lens array product.
Other unspecified parts are the prior art.Although above-described embodiment is made that the present invention and retouches in detail
State, but it is only a part of the embodiment of the present invention, rather than whole embodiments, people can also according to the present embodiment without
Other embodiments are obtained under the premise of creativeness, these embodiments belong to the scope of the present invention.
