The substrate 2 or the Worker's Stadium to be added of semi-solid preparation can be effectively formed, therefore circular cone pressure roller 3 can be facilitated to roll out corresponding concentric circles
Or isocentric circular arc structure.While it is readily appreciated that the substrate 2 or the Worker's Stadium to be added of semi-solid preparation are actually all by the eyeglass of semi-solid preparation
Material is formed, therefore the solidification process for solidifying the lens materials that component 5 accelerates semi-solid preparation can be used after rolling over.Thus,
Be conducive to improving the production efficiency of Fresnel lenses.Wherein, solidification component 5 is, for example, the heating wire for the top for being arranged on pedestal 6.
In this embodiment, spraying component 4 and solidification component 5 do synchronous revolution with circular cone pressure roller 3, and make circular cone pressure roller
3 are between spraying component 4 and solidification component 5 all the time in the circumferential.Device 10 can so be made according to spraying, rolling and solidified
Order manufacture Fresnel lenses so that its automaticity is significantly improved, so that beneficial to production efficiency is improved, saving is produced into
This.
As shown in Fig. 2 circular cone pressure roller 3 includes cone 301, a series of axially spaced is opened in the outer of cone 301
Ring roll piece 302 on week.However, it is readily understood that cone 301 and ring roll piece 302 may be configured to integral structure,
Or ring roll piece 302 is fixed on cone 301.Wherein, the characteristic that can be rotated using cone around its tip, is contributed to
Circular cone pressure roller 3 realizes revolution motion, therefore circular cone pressure roller 3 can be facilitated to be rolled out on a substrate 2 respectively using ring roll piece 302
Individual corresponding concentric circles or isocentric circular arc structure.It is readily appreciated that, the radial section of each ring roll piece 302 is and Fresnel mirror
The shape of the radial section of the single tooth of piece groove is mutually complementary.Thus, qualified Fresnel lenses can just be produced.
Second embodiment shown in Fig. 3 is the improvement based on one embodiment shown in Fig. 1, its specific improvements
It is as follows.Pedestal 6 includes multiple surface 6a being spaced apart from each other, and for multiple surface 6a batch (-type)s for carrying substrate 2
Ground is sent to the drive mechanism in the machining position that can be rolled into by circular cone pressure roller 3.In this way, it is possible to achieve the device 10
Similar to the production of pipeline system, production efficiency is further improved, so as to save production cost.The machining position is understood as
Region is rolled into by circular cone pressure roller 3, and drive mechanism is preferably conveyer.
Fig. 4 shows the 3rd embodiment for being used to manufacture the device of Fresnel lenses of the present invention.3rd embodiment
It is the improvement done for the pedestal 6 of the device 10 of one embodiment.Pedestal 6 includes can be around own axes edge and circular cone pressure roller 3
The smooth roll 60 that the opposite direction of rotation rotates.Smooth roll 60 can do synchronous revolution motion with circular cone pressure roller 3.Wherein, substrate 2 is pressed from both sides
Hold between smooth roll 60 and circular cone pressure roller 3.After smooth roll 60 follows the synchronous public affairs of circular cone pressure roller 3 to circle, circular cone pressure roller 3 can be
Multiple radiuses concentric structure incremented by successively is rolled out on substrate 2, so as to form Fresnel lenses.This double-roll type is set
Put, the integrated model of the device 10 can be promoted compact, reduction produces the cost of the device 10.Smooth roll 60 is preferably cone
Plain roller, thus can also be easy to smooth roll 60 to do revolution motion.
In addition, present invention also offers a kind of method for manufacturing Fresnel lenses, it includes：Substrate arranged in upper
Between the pedestal 6 and circular cone pressure roller 3 of stating the device 10 of the present invention；By circular cone pressure roller 3 around the rotation of own axes and relative to
Pedestal 6 can roll out multiple radiuses concentric circles incremented by successively on a substrate 2 or concentric around the sophisticated A of circular cone pressure roller 3 revolution
Arc structure, so as to form Fresnel lenses.By this method, circular cone pressure roller 3 can be in rolling process by vertical
Pressure rolls out multiple radiuses concentric circles incremented by successively or isocentric circular arc structure on a substrate 2, thus its will not produce it is larger
Tangential force promotes substrate 2 to be shifted over or offset, and can so be effectively prevented from the qualification rate of reduction manufacture Fresnel lenses.
According to the present invention, substrate 2 can select following 3 kinds of arrangements.First, the lens materials of liquid are sprayed at base
On seat 6, so as to form the substrate 2 of semi-solid preparation.Second, the substrate 2 of solid-state is arranged between pedestal 6 and circular cone pressure roller 3, then

Solidification process can effectively be accelerated, so as to improve the production efficiency of Fresnel lenses.
According to the device and method for being used to manufacture Fresnel lenses of the present invention, rolled out by circular cone pressure roller 3 multiple
The Fresnel lenses of radius concentric circles incremented by successively or isocentric circular arc structure, rely primarily on vertical pressure in this manufacturing process
Power manufactures Fresnel lenses, and therefore, it will not produce larger tangential force to promote substrate 2 to be shifted over or offset, and thus may be used
To be effectively prevented from the qualification rate of reduction manufacture Fresnel lenses.According to the present invention be used for manufacture Fresnel lenses device and
Method, as long as when producing larger Fresnel lenses, the radius or half of diagonal line length of Fresnel lenses are not more than conical pressure
The range of work of roller, will not cause cost to dramatically increase because of the size variation of Fresnel lenses, so that also would not be significantly
Ground reduces production efficiency.
Although by reference to preferred embodiment, invention has been described, is not departing from the situation of the scope of the present invention
Under, various improvement can be carried out to it and part therein can be replaced with equivalent.Especially, as long as in the absence of structure punching
