The distance between display screen and light supply apparatus save the inner space of photocuring 3D printer, reduce light and propagate in the medium
When energy loss.
Detailed description of the invention
Fig. 1 is the light supply apparatus cross-sectional view of the utility model；
Fig. 2 is the light exposure pathways schematic diagram of the utility model.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in further detail.
As shown in Figure 1, the photocuring 3D printer of the present embodiment, including pedestal, circuit control device, telecontrol equipment, beat
Print platform, resin storage tank (being not shown in the above component diagram), display screen 10, radiator 20 and light supply apparatus 30.Wherein, light source
Device 30 is fixed on radiator 20, and connects circuit control device, and is located at the underface of display screen 10.
Specifically, light supply apparatus 30 includes substrate 31, and it is fixed on the substrate 31 and in the light source 32 of array distribution, each
It is correspondingly provided with a convex lens 34 right above light source 32, and is fixed on the top of substrate 31 by bracket 33；Wherein, convex lens 34
Outwardly, plane is towards light source 32 on convex surface；First through hole 35, diameter are designed at the position of the corresponding each convex lens 34 of bracket 33
It is greater than light source 32 less than convex lens 34.
As shown in Fig. 2, the light that light source 32 issues may pass through first through hole 35, after reaching convex lens 34, reflects, make
The light of diverging collapses, and irradiation forms hot spot on the display screen 10.Convex lens 34 and light source 32 are kept into a suitable distance,
Stray light can be excluded, collapses the light through convex lens 34 more.The light reflected due to single source 32 and convex lens 34
Line is not directional light, so, the light intensity of spot center is stronger, and the light intensity on periphery is weaker.It and is in battle array by light source 32 and convex lens 34
After column-shaped distribution, the light of each hot spot edge can be mutually superimposed, to compensate the light intensity of edge, makes global illumination
Intensity distribution is more uniform.
Therefore, it can be applied directly in photocuring 3D printer from the light transmitted in convex lens 34, therefore light source can be shortened
The distance between device 30 and display screen 10 save the space inside photocuring 3D printer, are advantageously implemented photocuring 3D and beat
The desktop of print machine.Specifically, in the present embodiment, the distance between light supply apparatus 30 and display screen 10 can shorten to described convex
1.5 times of 34 focal length of lens are less than 10-15mm.
In addition, in the present embodiment, convex lens 34 using can quartz material resistant to high temperature, curvature between R2-R30,
It specifically can be according to convex lens 34 at a distance from light source 32 and convex lens 34 is at a distance from display screen 10 and between lens array
It is determined away from COMPREHENSIVE CALCULATING.
Specifically, to further increase uniform intensity degree, the light source 32 and convex lens 34 of the present embodiment are in honey-comb shape array
Distribution, can make the repeat region in array be preferably minimized value.In the present embodiment, the light source 32 is using LED chip as hair
Optic component, those skilled in the art can also use other kinds of light source according to the actual situation, not affect the utility model
Implementation.
Specifically, to further fix the convex lens 34, the present embodiment further includes being fixed on 33 top of bracket
Pressing plate 38, correspond to thereon be designed at the position of each convex lens 34 diameter be slightly smaller than convex lens 34 and be greater than light source 32 second
Through-hole 39 does not block the light through convex lens 34 as far as possible.Pressing plate 38 can be used stainless steel and other metal materials and be made.Pressing plate 38
It can be fixedly connected by modes such as screws between bracket 33.
Specifically, in the present embodiment, the top of bracket 33 is in boss-shaped, and the groove of boss 36 is connected and fixed convex lens
34, specifically can be by the fixed convex lens 34 of the modes such as gluing, the top of boss 36 can connect pressing plate 38 by modes such as screws.Branch
It the bottom of frame 33 can also be fixed on the substrate 31 by modes such as screws.In addition, the inner wall 37 of the first through hole 35 of bracket 33 is adopted
With hardening oxidation process at the not black wall of reflection light substantially, it is absorbed the light beaten on inner wall 37, can be ignored not
Meter further improves uniform intensity degree.
The characteristics of in addition, in the present embodiment, the bracket 33 uses aluminum alloy materials, has both thermally conductive and heatproof.
Specifically, in the present embodiment, 31 bottom of substrate is coated with heat-conducting glue, then is fixed by screws in radiator 20
On.Copper metal material can be used in substrate 31, and thermal conductivity is good, or the material of copper sheet is inlayed using ceramic substrate, then cooperates heat dissipation
Gasket can faster more in time radiate to light source 32, to extend the service life of light-emitting component.
Certainly, the replacement such as water-cooled module, those skilled in the art also can be used in addition to radiating gasket can be used in radiator 20
Member can use different radiating modes according to the actual situation, not affect the implementation of the utility model.
In conclusion the light that the light supply apparatus 30 of the utility model issues light source 32 passes through the refraction of convex lens 34, it can
The depth of parallelism of light is increased substantially, while the light that adjacent light source 32 issues has superposition on light-receiving surface, can compensate for surrounding
The strong weaker defect of edge light splitting, improves the uniformity of light distribution, so as to shorten between display screen 10 and light supply apparatus 30
Distance, save the inner space of photocuring 3D printer, reduce energy loss of light when propagating in the medium.
It is above to lift preferred embodiment, the purpose of this utility model, technical solution and advantage have been carried out further specifically
It is bright, it should be understood that the above is only the preferred embodiment of the utility model only, it is practical not new to limit this
Type, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in this
