TECHNICAL FIELD

[0002] Organic light-emitting diode (OLED) has become a mainstream technology in the field of display technology due to its self-emitting, simple structure, ultra-thin, fast response, wide viewing angle, low power consumption, flexible display and other excellent performances. Quantum dot light-emitting diode (QLED) has the advantages of saturated color and adjustable wavelength, and high photoelectric quantum yield, and has become a strong competitor of OLED in recent years.

[0003] In the manufacturing process of OLED devices and QLED devices, the devices need to be packaged. In order to ensure good water and oxygen barrier effect and flexible bending performance, flexible film packaging is generally used. At present, the mainstream film packaging process is a multi-layer structure, that is, on the basis of traditional chemical vapor deposition (CVD) inorganic film, inkjet printing is performed, and after leveling, a layer of organic material film (such as polyacrylate film) is formed to improve the flatness of the film, reduce mechanical damage and film defects, prolong the water and oxygen intrusion path, relieve interlayer stress, and improve the bending resistance of the film.

[0004] The inkjet printing device is used to accurately print ink materials of a specified size and volume on a substrate plated with a CVD inorganic film. The material diffuses and spreads for a period of time to form a liquid film. The liquid film is irradiated by a UV lamp of a specific wavelength and intensity to absorb energy and cross-link to form a dense polymer organic layer.

[0005] However, the traditional inkjet printing device is provided with a carrying platform for carrying the substrate.

Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein only for the purpose of describing specific embodiments and is not intended to limit the application. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0038] Please refer toFigure 1 and Figure 2 As shown, an inkjet printing and curing device 100 according to an embodiment of the present invention includes a carrier device 110, an inkjet printing device 120, and a photocuring device 130.

[0039] The carrier device 110 includes a carrier platform 111 and a first transfer mechanism 112. The carrier platform 111 is used to place the substrate. The first transfer mechanism 112 is connected to the carrier platform 111 and is used to drive the carrier platform 111 to move to the printing station 101 or the curing station 102.

[0040] The inkjet printing device 120 is used to print ink on a substrate located at the printing station 101.

[0041] The photocuring apparatus 130 includes a second transfer mechanism 132 and a UV curing lamp 133. The second transfer mechanism 132 is connected to the UV curing lamp 133 and is used to drive the UV curing lamp 133 to move along the support platform 111 at the curing station 102 to cure the ink.

[0042] When forming a thin film on a substrate using the inkjet printing and curing equipment 100 described above, the substrate is placed on the support platform 111, and the first transfer mechanism 112 is controlled to drive the support platform 111 to the printing station 101. Then, the inkjet printing device 120 is controlled to print ink on the substrate located at the printing station 101. After the ink is printed, the first transfer mechanism 112 is controlled to drive the support platform 111 to the curing station 102, and then the second transfer mechanism 132 is controlled to drive the ultraviolet curing lamp 133 to move along the support platform 111 at the curing station 102 to cure the ink. Compared with the traditional inkjet printing equipment that moves the substrate under the ultraviolet lamp during the curing process, this avoids the problem of unevenness of the overall film after curing due to the vibration of the ink on the substrate during the curing process.

[0043] like Figure 2 As shown, in one example, the light curing device 130 also includes a mounting base 131, a UV curing lamp 133 disposed on the mounting base 131, and a second transfer mechanism 132 connected to the mounting base 131 for driving the mounting base 131 to move.

[0044] Furthermore, in one example, the mounting base 131 includes a base 1312 and a bracket 1314. A second transfer mechanism 132 is connected to the base 1312 and is used to drive the base 1312 to move, thereby moving the mounting base 131 as a whole. The bracket 1314 is disposed on the base 1312 and has a gantry structure. The UV curing lamp 133 is disposed on the bracket 1314, and there is a passage gap between the UV curing lamp 133 and the base 1312 for the support platform 111 to pass through.

[0045] In one of the examples, the second transfer mechanism 132 is a lead screw driving assembly. In the specific example shown, the second transfer mechanism 132 includes a transfer seat 1322, a first driving lead screw 1324, a first driving motor 1326, and guide rods 1328. The first driving lead screw 1324 is arranged on the transfer seat 1322 and is threadedly connected with the base 1312, one end of the first driving lead screw 1324 is connected with the first driving motor 1326 and is driven to rotate by the first driving motor 1326. The guide rods 1328 are two in number and are arranged on the two sides of the first driving lead screw 1324 respectively. The guide rods 1328 are arranged on the transfer seat 1322 and penetrate through the mounting seat 131, and the guide rods 1328 are arranged in parallel with the first driving lead screw 1324.

[0046] It can be understood that in other examples, the number of the guide rods 1328 is not limited to two, for example, it can also be one, three, four, etc. In addition, the second transfer mechanism 132 can also not be provided with the guide rods 1328.

[0047] In one of the examples, the power of the ultraviolet curing lamp 133 is adjustable.

[0048] Since the ultraviolet curing lamp 133 (usually LED) will attenuate during operation, the inkjet printing and curing device 100 of the above example designs the power of the ultraviolet curing lamp 133 to be adjustable, so as to control the ultraviolet curing lamp 133 to be at a suitable power, avoiding the situation that the attenuation of the ultraviolet curing lamp 133 causes insufficient curing.

[0049] As shown in FIG. 1, Figure 2 In one of the examples, the light curing device 130 further includes an illuminometer 134, which is used to detect the illuminance value of the ultraviolet curing lamp 133.

[0050] The inkjet printing and curing device 100 of the above example is provided with the illuminometer 134 to detect the illuminance value of the ultraviolet curing lamp 133, so as to monitor the attenuation of the ultraviolet curing lamp 133 and facilitate the power adjustment of the ultraviolet curing lamp 133.

[0051] Further, in one of the examples, the light curing device 130 further includes a control device (not shown in the figure). The control device is electrically connected with the illuminometer 134 to obtain the illuminance value detected by the illuminometer 134. The control device is also electrically connected with the ultraviolet curing lamp 133, and is used to adjust the power of the ultraviolet curing lamp 133 according to the illuminance value, so as to make the illuminance value of the ultraviolet curing lamp 133 be within a set range. The set range of the illuminance value can be set according to the requirements of ink curing, so that the light power can reach the energy required for the photoinitiator in the ink to reach the excited state.

[0052] The inkjet printing and curing device 100 of the above example is provided with a control device electrically connected with the illuminometer 134 and the ultraviolet curing lamp 133. The control device receives the illumination value fed back by the illuminometer 134, and adjusts the power of the ultraviolet curing lamp 133 according to the received illumination value, so that the illumination value of the ultraviolet curing lamp 133 is in a stable state, and the stability of the product quality is ensured.

[0053] It can be understood that the illuminometer 134 can continuously detect and feed back the illumination value to the control device in real time, or can detect and feed back at a fixed time.

[0054] As shown in Figure 2 In one of the examples, the light curing device 130 further comprises a lifting mechanism 135 connected to the ultraviolet curing lamp 133, and the lifting mechanism 135 is used to drive the ultraviolet curing lamp 133 to rise or fall.

[0055] The inventors found that in order to ensure the integral illumination of ink curing, the irradiation power of the ultraviolet lamp is increased, but the irradiation power is increased at the same time, which tends to accelerate the decay of the ultraviolet lamp and reduce the service life of the ultraviolet lamp. Generally, the ink used in inkjet printing thin film packaging is acrylic ink, which needs to be cured in a nitrogen environment with an oxygen content of not more than 100 ppm. Therefore, the replacement of the lamp tube will cause the waste of production capacity and purification materials. In addition, due to the difference in processing precision of different manufacturers, the distance between the ultraviolet lamp beads produced is different, which tends to cause differences in light uniformity between the lamp beads.

[0056] Compared with the conventional design, the inkjet printing and curing device 100 of the above example is provided with a lifting mechanism 135 for driving the ultraviolet curing lamp 133 to rise or fall. In this way, by adjusting the height of the ultraviolet curing lamp 133, the above problems can be improved. In actual use, the height of the ultraviolet curing lamp 133 can be adjusted as needed, such as lowering the height of the ultraviolet curing lamp 133 to make it closer to the transfer platform, ensuring the integral illumination of ink curing, slowing down the decay of the ultraviolet curing lamp 133, and improving the service life of the ultraviolet lamp. For example, the height of the ultraviolet curing lamp 133 is raised to make it farther away from the transfer platform, reducing the problem of differences in light uniformity between the lamp beads due to the difference in distance between the ultraviolet lamp beads. Figure 3 and Figure 4 As shown in Figure 3 and Figure 4 The higher the height of the ultraviolet curing lamp 133, that is, the farther away from the substrate, the lower the illumination, and the better the light uniformity. Conversely, the lower the height of the ultraviolet curing lamp 133, the higher the illumination, and the worse the light uniformity.

[0057] In one of the examples, the lifting mechanism 135 is a lead screw driving assembly, which comprises a second driving motor 1352 and a second driving lead screw 1354.

[0058] In one of the examples, the UV curing lamp 133 comprises a lamp holder and a plurality of lamp beads arranged on the lamp holder, the plurality of lamp beads are spaced and uniformly arranged, and the arrangement direction of the plurality of lamp beads is perpendicular to the moving direction of the UV curing lamp 133.

[0059] As shown in the drawings, in one of the examples, the light curing device 130 further comprises a third moving mechanism 136 connected to the illuminometer 134 for driving the illuminometer 134 to move along the arrangement direction of the lamp beads, so as to detect the illuminance of different areas. Figure 1

[0060] In one of the examples, the third moving mechanism 136 comprises a moving guide rail and a third driving motor, the moving guide rail is arranged on the lamp holder of the UV curing lamp 133, the illuminometer 134 is arranged on the moving guide rail, and the third driving motor is used to drive the illuminometer 134 to move along the moving guide rail.

[0061] In the inkjet printing and curing device 100 of the present application, the inkjet printing device 120 and the light curing device 130 can be integrated in the same chamber, compared with the conventional design which needs to arrange a printing chamber and a curing chamber respectively, the manufacturing cost of the device can be reduced.

[0062] Further, the present application also provides an inkjet printing and curing method. The method uses the inkjet printing and curing device 100 of any of the above examples, and comprises the following steps:

[0063] Placing a substrate on the carrying platform 111;

[0064] Controlling the first transfer mechanism 112 to drive the carrying platform 111 to move to the printing station 101;

[0065] Controlling the inkjet printing device 120 to print ink on the substrate located at the printing station 101;

[0066] Controlling the first transfer mechanism 112 to drive the carrying platform 111 to move to the curing station 102;

[0067] Controlling the second transfer mechanism 132 to drive the UV curing lamp 133 to move along the carrying platform 111 at the curing station 102, so as to cure the ink.

[0068] The following specific embodiments are provided to illustrate the present application, but the present application is not limited to the following examples, and it should be understood that the appended claims generalize the scope of the present application. Those skilled in the art should realize that certain changes made to the embodiments of the present application will be covered by the spirit and scope of the claims of the present application.
