DESCRIPTION OF EMBODIMENTS

The following description and drawings sufficiently illustrate specific embodiments of the present disclosure to enable those skilled in the art to implement them. Other embodiments may include structural, logical, electrical, procedural or other changes. The examples represent only possible variations. Unless expressly required, individual components and functions are optional and the order of operations may be varied. Portions and features of some embodiments may be included in other embodiments or substituted by portions and features of other embodiments. The scope of embodiments of the present disclosure is defined by the claims, and all available equivalents thereof. These embodiments of the present disclosure may be referred to herein by the term “invention” individually or collectively for convenience only. If more than one invention is actually disclosed, the scope of the present disclosure does not automatically limit the present disclosure to any single invention or inventive concept.

It should be noted that various technical features in embodiments of the present disclosure can be combined with one another if there is no conflict.

A first aspect of the present disclosure discloses a photocuring device. As shown in FIG. 1 to FIG. 3, FIG. 1 is a structural example I of a photocuring device according to an embodiment of the present disclosure, FIG. 2 is a structural example II of a photocuring device according to an embodiment of the present disclosure, and FIG. 3 is a display example of a digital mask according to an embodiment of the present disclosure. A photocuring device 100 includes: a light source 10, a tray 20, and a digital mask 30 between the light source 10 and the tray 20. The light source 10 is configured to emit light required for photocuring. The tray 20 is configured to place a substrate 200 to be processed. The digital mask 30 is configured to display a corresponding light-shielding pattern 31 according to electronic graphics set by a user, so that the light emitted from the light source 10 penetrates the digital mask 30 to perform photocuring corresponding to the light-shielding pattern 31 on the substrate 200 placed on the tray 20. In some embodiments, the photocuring device further includes: a base 40 for fixing the light source 10, the tray 20 and the digital mask 30.

The digital mask 30 in embodiments of the present disclosure is an electronic display panel, which can control each pixel point on the display panel by a system, and form light-shielding pixel points/transmitting pixel points according to certain control requirements. A combination of these light-shielding pixel points constitutes a light-shielding pattern 31, and a combination of light-transmitting pixel points constitutes a light-transmitting pattern 32 opposite to the light-shielding pattern. The light-shielding pattern 31 and the light-transmitting pattern 32 are combined together to form an entire display surface of the display panel.

The electronic graphics set by the user can be consistent with the light-shielding pattern 31, while the light-transmitting pattern 32 is complementary to the electronic graphics. In other examples, the electronic graphics set by the user can also be consistent with the light-transmitting pattern 32, and the light-shielding pattern 31 is complementary to the electronic graphics. A relationship between the electronic graphics, the light-shielding pattern, and the light-transmitting pattern can be set/designed in software by developers and users.

The electronic display panel in embodiments of the present disclosure may be any digitally controlled light-shielding/transmitting display panel on the market that can meet the above requirements. The display panel is, for example, an LCD display panel, an OLED display panel, and the like. For traditional display panels, the display panel unpowered has black/green screen color, and each pixel point can become light-shielding/transmitting according to display requirements when powered on. For example, a traditional LCD liquid crystal display panel generally includes a first polarizing layer, a first electrode layer, a liquid crystal layer, a second electrode layer, and a second polarizing layer that are stacked in sequence. The first electrode layer and the second electrode layer controls the liquid crystal layer between the first electrode layer and the second electrode layer, so that light transmitting and light-shielding of the corresponding pixel points are performed. The display principle of the LCD display panel is common knowledge and will not be elaborated here. In some embodiments, a display panel suitable for the present disclosure can be obtained by purchasing a display screen on the market and removing a light-emitting backboard and a reflective layer of the display screen.

Regarding the light-shielding and light-transmitting discussed in embodiments of the present disclosure, dark color (opaque) display is adopted to obtain a light-shielding effect, and light color (transparent) display is adopted to obtain a light-transmitting effect.

In addition to the traditional display panels, the transparent (light-transmitting) display panels currently on the market can also meet the light-shielding/light-transmitting requirements of the pixel points in embodiments of the present disclosure, that is, dark color (opaque) display is adopted to obtain a light-shielding effect, and the rest remains transparent.

The photocuring device according to the present disclosure displays the light-shielding pattern corresponding to the electronic graphics through the digital mask according to the user's requirements, so that the light-shielding/light-transmitting of each area on the plane of the digital mask can be satisfied, thereby achieving the patterning light required by the user. In embodiments of the present disclosure, due to the numerical control advantage of the digital mask, the user's diversified optical patterning requirements can be met without mask manufacturing process, the processing efficiency is improved, device requirements are reduced, and manufacturing cost is saved.

In general, the light source 10, the tray 20 (the substrate 200), and the digital mask 30 in embodiments of the present disclosure constitute a vertical structure, and may be placed by stacking in a vertical direction as shown in FIG. 1, or may arranged in a horizontal direction as shown in FIG. 4 or in any other angles relative to one another. In some embodiments, the positions of the light source 10, the tray 20 (the substrate 200) and the digital mask 30 may not completely satisfy the vertical arrangement but still can achieve a certain degree of the technical effect, or may configure additional light steering components, which may increase device cost and device complexity.

In some embodiments, in order to achieve the vertical structure among the light source, the digital mask and the tray (substrate), the photocuring device may include necessary supporting and fixing structures such as supports, brackets, and frames.

In some embodiments, a distance between the light source 10 and the digital mask 30 may range from 10 mm to 500 mm. In some embodiments, the distance between the light source 10 and the digital mask 30 is set to be 100 mm to 250 mm Within this range, the influence of divergent light (light not perpendicular to the digital mask 30) emitted by the light source 10 on photocuring accuracy can be reduced, so that the light accuracy of photocuring device is improved. On the other hand, within this range, it can ensure that the light intensity of the digital mask emitted from the light source, thereby reducing the photocuring time, improving the efficiency of photocuring, and reducing the energy consumption of the device. Moreover, this range is also conducive to miniaturization requirement of the photocuring device, and can avoid the problem of excessively large size of the device caused by an excessively long optical path.

In some embodiments, a distance between the digital mask 30 and the substrate 200 on the tray 20 may range from 0 mm to 30 mm Within this range, the influence of divergent light on light accuracy can be reduced, so that the light penetrating the digital mask 30 irradiates on a target region of the substrate 200 opposite to it as much as possible, rather than on a non-target region of the substrate 200. In some embodiments, the distance between the digital mask 30 and the substrate 200 on the tray 20 can be in a range of 0 mm to 5 mm. On the one hand, it can well reduce the influence of divergent light, and on the other hand, it is easy to implement placement/replacement of the substrate, and facilitate alignment between the substrate and the digital mask, thereby avoiding scratches on the substrate and the digital mask caused by contact friction between the substrate and the digital mask during the alignment.

The distance between the digital mask 30 and the tray 20 can be designed with reference to the above-mentioned distance between the digital mask 30 and the substrate 200, so that the distance between the digital mask and the substrate can satisfy the above requirements.

In some embodiments, the positions among the light source 10, the digital mask 30, and the tray 20 can be adjusted to meet the usage requirements of designers or users.

In some embodiments, the positions of the light source 10, the digital mask 30 and the tray 20 in the photocuring device 100 are fixed after release from factory. In view of a small distance between the digital mask 30 and the tray 20, placing/taking of the substrate 200 on the tray 20 is achieved by a sideslip manner, and the tray 20 can be provided with a corresponding chute according to the size of the substrate, to guide and catch the substrate for aligning and fixing.

As shown in FIG. 5 and FIG. 6, in some other embodiments, the photocuring device 100 may further include a moving component 21. The moving component 21 is connected to or cooperates with the tray 20 to drive the tray 20 to move into or move out from a position relative to the digital mask 30, so that when the tray 20 is moved out, the user can place/take the substrate, and after the substrate is placed, the tray 20 can be moved in to align the substrate 200 with the digital mask 30. The moving component 21 is not limited to a rotating structure, a sliding rail structure, a telescopic structure and the like.

In some embodiments, the moving component 21 can adopt a tray seat driven by a slide rail. The tray seat is mounted on the base 40 through the slide rail. The tray 20 is assembled on the tray seat. When the tray seat is drawn out through the slide rail, the user can operate the substrate. When the tray seat is fully pushed in, the substrate 200 on the tray 20 can align with the digital mask 30.

Fixing substrate 200 on the tray 20 in the embodiments of the present disclosure is not limited to a clamping platform, catching, clamping, adsorbing, sticking, and the like. In some embodiments, the tray 20 is provided with a positioning post for cooperating with a positioning hole on the substrate. The substrate is sleeved on the positioning post through the positioning hole to achieve positional fixation.

As shown in FIG. 7 to FIG. 8, in some embodiments, the photocuring device 100 may further include an approaching component 22. The approaching component 22 is connected to or cooperates with the tray 20, so that the tray 20 is driven to drive the substrate 200 to approach the digital mask 30 when/after the substrate 200 on the tray 20 is aligned with the digital mask 30, thereby reducing the distance between the substrate 200 and the digital mask 30, or even making the substrate 200 directly attached on the digital mask 30 to achieve the effect of zero distance between the digital mask 30 and the substrate 200. In addition, the design is beneficial to avoid friction between the substrate 200 and the digital mask 30, and reduce the probability of scratches on the substrate 200 and the digital mask 30. The approaching component 22 is not limited to a lift platform, a spring, a slide rail, a clamping platform, and the like.

As shown in FIG. 9 to FIG. 10, in some embodiments, the approaching component 22 may include: an inclining chute 221 provided on the tray seat. The inclining chute 221 has a guiding direction same as the moving direction of the tray seat, and inclines downward in a pushing-in direction of the tray seat. The tray 20 is assembled on the tray seat through the inclining chute 221 so that the tray 20 can move on the tray seat along the inclining chute 221. Since the inclining chute 221 inclines downward in the pushing-in direction of the tray seat, when the tray 20 moves in the pushing-in direction through the inclining chute 221, its position relative to the digital mask 30 has an increased vertical relative distance. On the contrary, when the tray 20 moves in the pulling-out direction through the inclining chute 221, its position relative to the digital mask 30 has a reduced vertical relative distance. Under normal circumstances, the tray 20 will tend to move, due to its own gravity, to a lower end of the inclining chute 221, and in the absence of external force, the tray 20 will always be at the lower end of the inclining chute 221. The approaching component 22 further includes a positioning baffle 222. The positioning baffle 222 is provided on a moving path of the tray 20 to block the movement of the tray 20, and cooperates with the tray seat and the inclining chute 221, aligning the substrate 200 on the tray 20 with the digital mask 30 and approaching to the digital mask 30. In this embodiment, when the tray seat is pushed in from outside to inside, the tray 20 is located at the lower end of the inclining chute 221. During the tray seat is gradually pushed in, the tray 20 is in contact with the positioning baffle 222, and starts to move backwards relative to the inclining chute 221 due to the blocking of the positioning baffle plate 222, so that the tray 20 gradually climbs along the inclining chute 221, thereby making the substrate 200 on the tray 20 approach the digital mask 30. After the tray seat is fully pushed in, when the tray 20 is located at a higher end position on the other side of the inclining chute 221, the substrate 200 on the tray 20 is aligned with the digital mask 30.

In this embodiment, by using the inclining chute 221, the positioning baffle 222, and the pushing-in operation of the tray seat, the substrate 200 can approach to the digital mask 30, and due to the function of the inclining chute 221, no relative friction is generated between the substrate 200 and the digital mask 30 during an aligning process of the substrate 200 with the digital mask 30.

As shown in FIG. 11 to FIG. 12, in some embodiments, the approaching component 22 may further include: a spring mechanism 223 provided on the back of the tray 20 (an opposite side relative to the substrate). When the tray 20 is located in a higher-end position of the inclining chute 221, the spring mechanism 223 release its elasticity to push the tray 20 against the digital mask 30, so that the substrate 200 further approaches the digital mask 30. In some embodiments, the tray 20 is fixed on a bottom plate 224 by the spring mechanism 223. The bottom plate 224 slides into cooperation with the inclining chute 221 on the tray seat.

Furthermore, the positioning baffle 222 and the tray 20 may be provided with magnetic attraction components that cooperate with each other. The magnetic attraction components are configured to apply a driving force to the tray to move it to its lower end along the inclining chute 221. This embodiment is configured to enhance the effect of gravity, so that the tray can actively approach the inclining chute 221 as much as possible during its sliding process.

In some embodiments, the light source 10 in embodiments of the present disclosure is suitable for light with any wavelength band. When a wavelength band harmful to human body is used, a light shield 50 can be provided between the light source 10 and the digital mask 30.

As shown in FIG. 13, in some embodiments, the light source 10, the light shield 50 and the digital mask 30 form a sealed cavity. Only when the light source and the digital mask work together, the light source emits light with consistent pattern from the digital mask of the sealed cavity. In this embodiment, the light source and the digital mask can be arranged at opposite sides of the light shield, for example, the light source 10 is arranged on the top of the light shield 50 and irradiates downward, and the digital mask is arranged on the bottom of the light shield opposite to the light source.

In some embodiments, the sealed cavity formed by the light source, the light shield and the digital mask is a vacuum structure to prevent impurities from affecting light propagation.

The housing can be a fully sealed housing or a semi-sealed housing, so as to achieve the overall or partial shielding/packaging of the device. For the fully sealed housing structure, it can be achieved by a combined structure. In some cases, the user can open the combined structure to replace/adjust the substrate, components, etc. After the operation is completed, the housing is combined to seal. In some embodiments, the housing 60 and the base 40 may be formed as an integral structure.

Alternatively, the data interface component is directly connected to an external storage device to obtain electronic graphic data used by the digital mask in the storage device. The data interface component is connected to the control module.

In some embodiments, the photocuring device further includes a necessary power supply module, which will not be elaborated here.

In some embodiments, the photocuring device may further include a heat dissipation component to dissipate the heat of the photocuring device, ensuring continuous and stable operation of the photocuring device.

A side of the reflective back plate close to the light-emitting element has a metal emitting surface for concentrating light at a side of the light-emitting element. In some embodiments, the heat dissipation component is mounted on the other side of the reflective back plate away from the light-emitting element, so as to take away the heat generated by the light source.

As shown in FIG. 15, in some embodiments, an optical lens 12 is provided between the light source 10 and the digital mask 30 to convert divergent light emitted by the light source 10 into uniform light in direction perpendicular to the digital mask 30. The optical lens 12 can be made of plastic, quartz glass and other materials.
