3D printing is new rapid prototyping ＆ manufacturing technology.It manufactures product by multiple-layer stacked growing principle.It can overcome
The special construction obstacle that tradition machinery processing can not be realized.The simplification production of arbitrarily complicated structure member can be realized.It is existing
3D printing technique be divided into:Thermoplastic cement technology FDM；Laser sintering and moulding technology；Photocurable liquid Choice of Resin is regions curing
Forming technique.And liquid resin selection region curing molding technology is divided into：Laser scanning imaging photocuring technology (SLA)；Throw
Shadow instrument image conversion irradiates forming technique（DLP）；Display screen is imaged ultraviolet frequency spectrum photocuring technology（LCD）.
LCD photocuring principles are, using liquid crystal display LCD image-forming principles, in microcomputer and display drive circuit
Under driving, picture signal is provided by computer program.Occurs selective black and white region on LCD screen, white is transparent area
Domain, black is lightproof area.
In light source（The generally larger high frequency ultraviolet light of emittance）Irradiation under, the images transparent region of LCD screen
Ultraviolet light is obstructed and reduced, ultraviolet light can be passed through；In the region shown without image, ultraviolet light is blocked.Through liquid crystal
The ultraviolet light of screen constitutes ultraviolet light image region.
In the surface mount photocurable liquid resin storage tank of LCD screen, bottom land is transparent membrane, and ultraviolet light is by transparent
Film is irradiated to liquid photocurable resin, makes to produce solidification reflection, the liquid resin being irradiated to by the resin of ultraviolet light
As solid-state.LCD screen lighttight partial occlusion ultraviolet light.Be blocked part liquid photocurable resin not by
Ultraviolet light is irradiated to, and the part resin not being irradiated to remains in that liquid.Resin by solidification is exactly that our 3D are beaten
The formed product part of print machine manufacture.
LCD uv equipments light source has very strong heat radiation, and long-term radiation can have a strong impact on the use longevity of liquid crystal display
Life, radiant heat is excessive it is also possible to damaging liquid crystal display；Other resin solidification can also produce certain heat, can all act on liquid crystal
Screen.
To sum up chat, it is necessary to a kind of liquid crystal display cooling module-coldplate, to solve liquid crystal display heating problem, therefore, this hair
A person of good sense designs a kind of LCD liquid crystal display coldplates based on LCD photocuring 3D printers.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of can improve service life based on LCD photocuring 3D printings
The LCD liquid crystal display coldplates of machine.
In order to solve the above technical problems, the technical scheme is that：A kind of LCD based on LCD photocuring 3D printers
Liquid crystal display coldplate, its innovative point is：Including LCD screen, cooled plate and array of source, the cooled plate includes cooled plate A
With cooled plate B, it is equipped with cooling pipe, the cooled plate B on the cooled plate A and is provided with the water inlet that correspond to cooling pipe
Mouth and delivery port, the cooled plate A are assembled on cooled plate B top, the cooled plate A and open up fluted, the liquid crystal display
Curtain is assembled in the corresponding grooves of cooled plate A, and the array of source is arranged on cooled plate B lower section.
Further, it is equipped with water pipe head on the water inlet and delivery port on the cooled plate B.
Further, PMMA, PC high transmission rate material of cooled plate selection light transmittance >=95% are made.
Further, the cooled plate A and cooled plate B are bonded using waterproof shadowless glue and in vacuum environment operation.
Further, the LCD screen and cooled plate contact surface are fitted close.
The advantage of the invention is that：
（1）The related factor of temperature rise to LCD screen includes：Light source power, light source area, the distance of light source distance liquid crystal display,
Time for exposure etc., in the case that above parameter is fixed, screen temperature can be greatly lowered in the LCDs for having cooled plate, carry
High service life.
（2）Cooled plate selects PMMA, PC high transmission rate material of light transmittance >=95%, improves light source utilization rate.
（3）Cooled plate A and cooled plate B are bonded using waterproof shadowless glue and in vacuum environment operation, and coolant is interior when circulating
Portion's pressure is big, prevents leakage, prevents producing bubbles inside, influences thang-kng rate.
（4）LCD screen and cooled plate contact surface need to be fitted close, it is ensured that LCD screen temperature is uniform.
（5）Water pipe head is equipped with water inlet and delivery port on cooled plate B, coolant is passed through and tests whether sealing,
Cooled plate is cleaned simultaneously.
