Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application is described.

It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.Meanwhile the application's In description, term " first ", " second " etc. are only used for distinguishing description, are not understood to indicate or imply relative importance.

Fig. 1 is please referred to, Fig. 1 is the structural schematic diagram of photocuring 3D (three-dimensional) printing equipment provided by the embodiments of the present application, As shown in Figure 1, the photocuring 3D printing device include: control device 140 and the curing light source being connect with control device 110, Liquid crystal display 120 and molding machine 130；Wherein, curing light source 110 may include the multiple cure lamps arranged in the form of an array, often A cure lamp can individually open or close under the control of control device 140.The light directive liquid that curing light source 110 is emitted Crystalline substance screen 120.Liquid crystal display 120 can receive the mask image of the transmission of control device 140, carry out the display of mask image.Wherein, it controls The 3D model cutting of building can be obtained a sheet by a sheet cross-sectional image by operation Slice Software by device 140 processed, the cross-sectional image It is properly termed as mask image again.Control device 140 successively can send liquid crystal display for a sheet by a sheet cross-sectional image and show.

As shown in Fig. 2, Fig. 2 is a kind of mask image schematic diagram provided by the embodiments of the present application.The mask image can divide For white area and black region.According to the distinctive display characteristic of liquid crystal display, liquid crystal molecule is under the effect of different current electric fields, meeting The rotation for doing respective angles generates the difference of light transmittance, and principle controls the light and shade of each pixel according to this, can constitute artwork master Picture.Therefore when the display of liquid crystal display progress mask image, the liquid crystal molecule that white area may be considered the region has been applied electricity Pressure, Liquid Crystal Molecules Alignment is neat, and the light that liquid crystal screen backlight issues can penetrate, and belongs to transmission region, and black region can To be considered that the liquid crystal molecule in the region is not applied voltage, fall into disarray, the light that liquid crystal screen backlight issues can not be saturating Light belongs to light tight region.When i.e. liquid crystal display carries out mask image display, white area can cannot be saturating with light transmission, black region Light.

As shown in Figure 1, the light that curing light source 110 issues can be with directive display screen 120, since the display of liquid crystal display 120 is covered When film image, white area can be with light transmission and black region is unable to light transmission, as a result, the light of 110 directive white area of curing light source Line can be irradiated to molding machine 130 with light transmission display screen 120.Molding machine 130 can load liquid resin 131, liquid resin 131 are through the light irradiation of white area, and then solidify.Every to complete one layer of solidification, bracket 132 sends behind, display screen 120 It shows next mask image, continues the liquid resin 131 to top layer through the light of next mask image white area Solidified, thus successively solidification, produces three-dimensional entity model.

Currently, photocuring 3D printing device is at work, only one total switch of curing light source, all cure lamps open or Guan Jun is synchronous, cannot individually be controlled each cure lamp, and when solidifying each layer, all cure lamps are all in opening state. Since curing light source is using high-power purple outer light source, the plastic member and liquid crystal composition of liquid crystal display under ultraviolet light, It can rapid aging.And curing light source, usually between 50-200 watts, under the irradiation baking of intense UV light, liquid crystal display temperature can be rapid It improves, the liquid crystal display service life is caused to be greatly decreased.In addition, curing light source self-heating amount is also very big, the heat of generation can also make The service life of liquid crystal display and curing light source is greatly decreased.

In order to solve drawbacks described above, current primary solutions are to install large-scale cooling fin to add radiator fan, or dissipate Backing adds the mode of water cooling equipment to radiate；It is to reduce curing light source power there are also a kind of mode.But additional installation heat dissipation Piece, radiator fan or water cooling equipment, increase the structure complexity and cost of photocuring printing equipment, and reliability reduces.If Curing light source power is reduced, then will lead to that print speed is very slow, a hour can only print 1 centimetre of height.Even if in this way The service life of liquid crystal display also only has 1-3 months, that is, every 1-3 months will replace liquid crystal display.In use, core is frequently replaced Component (i.e. liquid crystal display and curing light source), cause it is difficult in maintenance, it is expensive.

That is, suitable method there is no to solve liquid crystal display because a large amount of ultraviolet lights irradiate rapid aging for a long time at present Problem.In practical applications, inventor has found most of mask image, and black region is far longer than white area, white Region in the accounting in mask image usually between 1%-20%, therefore liquid crystal display carry out mask image display when, solidify light The ultraviolet light that source issues can largely be blocked by the black region of liquid crystal display, and this part light being blocked is due to that can not irradiate To liquid resin, liquid resin is solidified and is not worked.It is opposite, since black absorbs heat very much, this part for being blocked Ultraviolet light can be converted into thermal energy, cause the temperature of liquid crystal display very high, accelerate the aging of liquid crystal display.Further, if To improve the power that curing rate increases curing light source, then it will lead to liquid crystal display temperature more than the use scope upper limit, directly result in Liquid crystal display is scrapped.Based on this, the application extends the service life of liquid crystal display, looks for another way, provide to slow down the aging of liquid crystal display A kind of control method of curing light source.

Fig. 3 is please referred to, Fig. 3 is a kind of control method of curing light source provided by the embodiments of the present application, the curing light source Multiple cure lamps including independent control；That is, the quantity of cure lamp included by curing light source is at least 2, solidification The quantity of lamp can be increased and decreased according to the size of liquid crystal screen dimensions, and liquid crystal screen dimensions are bigger, and the quantity of cure lamp is more.This Shen The control method for the curing light source that please be provide, can as shown in Figure 1 photocuring 3D printing device control device 140 execute, should Control device 140 can individually control each cure lamp on or off.The control method of the curing light source may comprise steps of:

Step 310: obtaining mask image to be shown；

Step 320: the transmission region being correspondingly formed in liquid crystal display display area according to the mask image, from described solid Change and filtered out in light source, emergent ray is irradiated to the cure lamp of the liquid crystal display transmission region, and it is corresponding to obtain the transmission region Cure lamp；

Step 330: in the corresponding layer of the solidification mask image, controlling the corresponding cure lamp of the transmission region and be in Open state, remaining cure lamp is in close state in addition to the cure lamp corresponding to the transmission region in the curing light source.

Below above-mentioned steps are unfolded to be described in detail.

In the step 310, mask image to be shown is obtained.

It is to be understood that mask image refers to the cross-sectional image of 3D model, in general, mask image may include white area Domain and black region, the white area of mask image is model section, when carrying out the display of mask image by liquid crystal display, white Region is transmission region in the display area of liquid crystal display.The black region of mask image is the background image of non-model, passes through liquid Black region is opaque when crystalline substance screen display, so black region is properly termed as occlusion area in the corresponding display area of liquid crystal display.

As needed, the model cross section in mask image is also possible to colour other than being indicated with white, such as red Color, blue, green etc., each pixel of liquid crystal display are segmented into three sub- pixels, show respectively through colored filter Red Green Blue, then via the reconciliation of RGB ratio, can show various colors.Therefore when the mould in mask image When type cross section is colour, the model cross section in mask image can also form transmission region in liquid crystal display.But due to Light can have loss by optical filter, therefore in one embodiment, liquid crystal display can show black white image without optical filter, Correspondingly, mask image may include the white area and lighttight black region for light transmission.Hereafter with black and white tone Mask image illustrates.

Mask image can obtain 3D model slice by Slice Software, and a 3D model can be sliced to obtain a series of cover Film image.Liquid crystal display can carry out the display of mask image frame by frame.Wherein, mask image can store in control device local, It can also be obtained by control device from other external equipments.Illustratively, one mask image of the every display of liquid crystal display, is covered for this The transmission region that film image is formed in liquid crystal display, the i.e. controllable corresponding cure lamp of liquid crystal display transmission region of control device are opened It opens, other cure lamps are closed.

It should be noted that one mask image of the every acquisition of control device is shown in liquid crystal display, it can synchronously control Curing light source is opened, and is made the white area of UV light permeability mask image, is solidified to liquid resin.And existing solidification light Only one master switch of source opens all cure lamps when carrying out every mask image display.And the application is covered in display When film image, the cure lamp for being irradiated to transmission region is only opened, closes other cure lamps.

Wherein, liquid crystal display display area refers to that the window can be whole for showing the window of mask image in liquid crystal display The pixel region of a liquid crystal display is also possible to a part of liquid crystal display pixel region.Mask image is in liquid crystal display display area When the transmission region being inside correspondingly formed refers to that liquid crystal display carries out the display of mask image, the white area of mask image is in liquid crystal display The region presented in display area.

Illustratively, mask image can be identical as the size of liquid crystal display display area, the pixel and liquid of mask image The pixel of crystalline substance screen corresponds.As needed, the size of mask image can be less than or equal to the size of liquid crystal display, make exposure mask figure As can completely be shown in liquid crystal display display area.As needed, mask image can also be zoomed in and out, it can be just It is shown in liquid crystal display display area.Regardless of mask image size, when liquid crystal display carries out the display of mask image, exposure mask The white area of image forms transmission region in liquid crystal display display area.

Wherein, the corresponding cure lamp of transmission region refers to the cure lamp for being irradiated to transmission region.It illustratively, can be prior The pixel of liquid crystal display is demarcated, that is, demarcates the pixel that each cure lamp can irradiate.According to transmission region packet The pixel that the pixel and each cure lamp contained can be irradiated to, can determine transmission region include pixel be to belong to The position which cure lamp can be irradiated to, to obtain the corresponding cure lamp of transmission region.

Illustratively, the region that can be irradiated according to cure lamp in liquid crystal display display area, if transmission region part or Region all comprising the solidification light irradiation, it may be considered that the cure lamp belongs to the corresponding cure lamp of transmission region.

In a step 330: in the corresponding layer of the solidification mask image, controlling the corresponding cure lamp of the transmission region In the open state, remaining cure lamp is in and closes shape in addition to the cure lamp corresponding to the transmission region in the curing light source State.

It is to be understood that when liquid crystal display carries out the display of mask image, due to only through the light ability of liquid crystal display Liquid resinous solidification can be played a role, and the light for being irradiated to liquid crystal display light tight region can not solidify to liquid resinous Effect, therefore the application is directed to the transmission region that mask image is formed in liquid crystal display display area, and it is corresponding only to control transmission region Cure lamp is opened, and other cure lamps are in close state, thus irradiation when avoiding long to the inoperative cure lamp of solidification Liquid crystal display causes liquid crystal display to be rapidly heated and accelerated ageing.

Wherein, when solidifying layer corresponding to mask image, refer to the transmission region solidify liquid needed for the mask image When state resin.In one embodiment, when controlling liquid crystal display progress mask image display, the synchronously control mask image institute shape At the corresponding cure lamp of transmission region, keep the corresponding cure lamp of the transmission region in the open state, other cure lamps are in Closed state.In one embodiment, mask image can be first shown, then under the mask image display state, control is saturating The corresponding cure lamp in light region is opened, other cure lamps are closed.In other embodiments, can first to control transmission region corresponding Cure lamp is opened, other cure lamps are closed, then control the display that liquid crystal display carries out the mask image.To make to be irradiated to transparent area The cure lamp in domain is opened, and the cure lamp without being irradiated to transmission region is in close state, and is irradiated to the light of transmission region Line solidifies liquid resin through liquid crystal display.

Illustratively, control device can be directed to every mask image in advance, find the transmission region pair of the mask image The cure lamp answered, then when liquid crystal display carries out the display of mask image frame by frame, control device is according to currently displayed exposure mask figure Picture, the transmission region of the synchronously control mask image correspond to cure lamp unlatching, and remaining cure lamp is closed.Assuming that curing light source has altogether There are 100 cure lamps, the corresponding cure lamp of transmission region there are 40, then other 60 cure lamps should be at closed state.? In a kind of embodiment, before solidifying each layer, all cure lamps are in closed state, need to only control transmission region at this time Corresponding cure lamp is opened.In another embodiment, before solidifying each layer, all or part of cure lamp has been opened, then The cure lamp for controlling transmission region is opened, and is controlled other cure lamps and is closed.

In one embodiment, above-mentioned steps 320 may include:

Wherein, curing light source is not the backlight of liquid crystal display, and all cure lamps of curing light source are irradiated to liquid crystal display and show Region, each cure lamp have corresponding irradiation area in liquid crystal display display area, illuminate range and just refer to cure lamp in liquid crystal The region of screen display area illumination.Illustratively, coordinate system can be established to liquid crystal display display area, demarcates each cure lamp Illuminate range, such as the range that illuminates of some cure lamp be abscissa is 5-7mm, the region that ordinate surrounds between 3-4mm.

Control device illuminates range and mask image in liquid crystal display in liquid crystal display display area according to each cure lamp The transmission region that display area is formed, can pick out the solidification that light can be irradiated to the transmission region from all cure lamps Lamp obtains the corresponding cure lamp of transmission region.Illustratively, coordinate system can be established to liquid crystal display display area, obtains light transmission The coordinate range in region, when the coordinate range of transmission region, part or all is in the illumination zone of some cure lamp, Then the cure lamp belongs to the corresponding cure lamp of transmission region.

On the basis of the above embodiments, in above-mentioned steps " according to cure lamp each in the curing light source in the liquid Range is illuminated in crystalline substance screen display area, filters out from the curing light source, emergent ray is irradiated to the liquid crystal display transparent area The cure lamp in domain obtains the corresponding cure lamp of the transmission region " before, method provided by the present application can also include:

That is, the range that illuminates of cure lamp can be used for pixel coordinate set representations.Pixel coordinate set refers to solid Change the set for the pixel that lamp can be irradiated in liquid crystal display display area.Illustratively, liquid crystal display display area can be built Vertical coordinate system, a pixel is as a unit.For example, the pixel coordinate set of some cure lamp can be abscissa For the 200-230 pixel, ordinate is the set of the pixel coordinate of the 340-370 pixel.Each solidification as a result, The range that illuminates of lamp can be as accurate as pixel.

On the basis of the above embodiments, above-mentioned steps are " according to cure lamp each in the curing light source in the liquid crystal Range is illuminated in screen display area, filters out from the curing light source, emergent ray is irradiated to the liquid crystal display transmission region Cure lamp, obtain the corresponding cure lamp of the transmission region ", may include:

Wherein, the pixel coordinate set of transmission region refers to what the coordinate of all pixels point in liquid crystal display transmission region was constituted Set.Control device can establish pixel coordinate system to liquid crystal display display area, that is, each pixel has corresponding picture Plain coordinate, such as the coordinate (x, y) of some pixel can indicate that the pixel is x-th of pixel on abscissa direction, It is y-th of pixel in the ordinate.The pixel that can be illuminated according to cure lamp in liquid crystal display display area as a result, And the available pixel coordinate set of coordinate of these pixels.The pixel for including according to transmission region and these The coordinate of pixel, the pixel coordinate set of available transmission region.
