Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with specific embodiment, and reference
Attached drawing, the present invention is described in further detail.
The semielliptical lens array and preparation method thereof that the invention discloses a kind of to be made based on flexible substrates, first with
3D printing technique prints oval substrate array, and light-sensitive material is instilled to oval base according to demand using glue dispenser with high precision
On the array of bottom, semielliptical lens formpiston is formed after cured, semielliptical lens former is then obtained by overmolded；Semielliptical is saturating
Mirror former is wrapped on designed cylindrical rod and obtains roll die, and roll die is attached on rolling coining platform, rolling is used
The semielliptical lens array of high-precision batch can be obtained in dynamic pressure print platform.
Specifically, as shown in Figure 1, the present invention provides a kind of sides based on flexible substrates production semielliptical lens array
Method, comprising the following steps:
Step 1: by 3D printing production one with reeded mold 3, the oval substrate battle array of protrusion is provided in groove
Column, as shown in Fig. 2 (a).
Wherein specifically it can be used 3 d modeling software such as SolidWorks, UG NX, ProE/Creo etc. to semielliptical lens
Substrate is designed, and is exported stl format, is reused high-precision 3D printer and print oval substrate array.3D printing essence
Degree should be controlled can be by the layer thickness control of printing at least in 32 micron dimensions, and relative error < 0.3%.
Wherein the oval substrate 1 of each design is as shown in Figures 2 and 3 in oval substrate array, transverse size one
As control within 3mm, the thickness of substrate is less than 0.3mm, in order to avoid rolling effect is bad.It is appreciated that the groove of mold is deeply slightly
Higher than oval substrate thickness, so as to the casting of subsequent second moulding material.
Wherein mold materials are selected not be bonded with the second moulding material and make the indeformable material of mold.
Step 2: being respectively dropped into the first moulding material on oval substrate array by dispenser 5 into semielliptical shape, drop
Enter amount to design to obtain according to half ellipsoidal surface shape, so that the first mold material cures is formed semielliptical lens array formpiston, such as Fig. 2 (b)
It is shown.

(polydimethylsiloxane, Chinese name dimethyl silicone polymer) material, no matter with semielliptical lens array anode membrane 7
Knockout course, or excellent release property is shown in the knockout course of subsequent rolling process.PDMS solution solidifies not
Can be by heater riser curing rate, heating meeting is so that oval substrate array deformation, therefore time of repose need under room temperature environment
Greater than 24 hours, to guarantee that solution is fully cured.
Step 4: semielliptical lens array former being coated on cylindrical rod 10, obtains being used to prepare semielliptical lens array
Roll die 9, as shown in Fig. 2 (d)；
Wherein, which can be mounted on rolling coining platform as the initial roll die without pattern image
It is used cooperatively, which is fixed on cylindrical rod 10 using double-sided adhesive.
Step 5: being rolled in the flexible substrates 11 for being coated with third moulding material using roll die 9, formed to third
After material solidification, obtain being formed in the semielliptical lens array in flexible substrates, as shown in Fig. 2 (e).
Wherein third moulding material is ultraviolet glue glue, and cure shrinkage should be selected than small, curing rate is fast, optical property
Good ultraviolet glue, if the 1551M2 that TEX YEAR is produced forms gluing glue 12 in flexible substrates 11 as shown in Fig. 2 (e),
Solidify under the irradiation of ultraviolet lamp 3 while rolling.
Wherein roll die be mountable to a rolling coining platform on rolled, according to experience rolling speed early period≤
When 0.5m/min, preferable rolling and solidification effect can be obtained.
Wherein flexible substrates 11 are the optical grade film of uv transmittance >=85%, such as the optics of high ultraviolet light
