Example 1:
as shown in fig. 1, the present embodiment provides a printing apparatus including: the device comprises an ink storage chamber 1, a resonant cavity 3, an adjusting module and a control module; wherein, the ink storage chamber 1 is used for providing ink to the resonant cavity 3; the resonant cavity 3 is provided with an ink inlet and an ink outlet, and the ink inlet is communicated with the ink storage chamber 1; the adjusting module is used for adjusting the vibration frequency of the resonant cavity 3 according to the type of the ink contained in the resonant cavity 3, so that the vibration frequency of the resonant cavity 3 is equal to the natural frequency of the ink contained in the resonant cavity 3, and the ink in the resonant cavity 3 vibrates; the control module is used for controlling the vibrated ink to be sprayed on the substrate 6 to be subjected to film formation through the ink outlet.
Since the resonant cavity 3 is disposed in the printing apparatus of this embodiment, the resonant cavity 3 can vibrate, and the vibration frequency is the same as the natural frequency of the ink contained therein, at this time, the ink in the resonant cavity 3 also vibrates according to the resonance principle. Thus, after the vibrating ink is jetted to the surface of the substrate 6, the ink can be uniformly distributed on the substrate 6 by the self aftershock, thereby solving the problem of poor film forming uniformity caused by non-uniform distribution of the ink jetted from the nozzle on the substrate 6 in the prior art.
Preferably, in this embodiment, the adjusting module specifically includes: the device comprises an identification unit, an acquisition unit and an adjustment unit; the identification unit is used for identifying the type of ink contained in the resonant cavity 3; the acquiring unit is used for acquiring the natural frequency of the ink in the resonant cavity 3 according to a pre-stored relation table of the natural frequencies of different types of ink and the type of the ink contained in the resonant cavity 3 and identified by the identifying unit; the adjusting unit is used for adjusting the vibration frequency of the resonant cavity 3 according to the natural frequency of the ink acquired by the acquiring unit.
That is, after the ink in the ink reservoir 1 is transferred into the resonant cavity 3, first, the identification unit identifies the type of the ink inputted into the resonant cavity 3; then, the obtaining unit obtains the natural frequency of the ink in the resonant cavity 3 according to a pre-stored relationship table of the natural frequencies of different types of ink and the type of the ink contained in the resonant cavity 3 identified by the identifying unit; finally, the adjusting unit adjusts the vibration frequency of the resonant cavity 3 according to the natural frequency of the ink acquired by the acquiring unit, so that the vibration frequency of the resonant cavity 3 is equal to the natural frequency of the ink contained therein.
Preferably, in this embodiment, the printing apparatus further includes: and one end of the pipeline 2 is connected with the ink storage chamber 1, and the other end of the pipeline is connected with the ink inlet.
It can be seen that the ink storage chamber 1 of the present embodiment is communicated with the ink inlet of the resonant cavity 3 through the conduit 2, that is, the ink in the ink storage chamber 1 passes through the conduit 2 and the ink inlet in sequence to be input into the resonant cavity 3. Of course, the means for communicating the ink storage chamber 1 with the ink inlet is not limited to the conduit 2 provided in the present embodiment, and is not limited thereto.
Preferably, in this embodiment, the control module includes: a pressure valve comprising a piston 4, a control rod (not shown in fig. 1); wherein, the piston 4 is arranged in the resonant cavity 3 and is fixedly connected with the control rod; the control rod is used for controlling the piston 4 to move in the resonant cavity 3 so as to apply pressure to the vibrating ink, so that the vibrating ink is sprayed onto the substrate 6 to be subjected to film formation through the ink outlet. Of course, the means for applying the vibrating ink to the substrate 6 is not limited to the pressure valve, and is not limited thereto.
Example 2:
as shown in fig. 2, the present embodiment provides a printing system, which includes the printing apparatus of embodiment 1, a screen printing plate 5; the screen printing plate 5 has a plurality of openings arranged in an array, so that the vibrating ink can be sprayed onto the substrate 6 through the openings to form the patterned film 7.
It should be noted that, when the printing system provided in this embodiment is used to perform inkjet printing on the surface of the substrate 6, the screen plate 5 is disposed between the resonant cavity 3 of the printing apparatus and the substrate 6, so that the ink vibrated in the resonant cavity 3 sequentially passes through the ink outlet of the resonant cavity 3 and the opening of the screen plate 5 to be sprayed onto the substrate 6 to be subjected to film formation, and thereby the patterned film layer 7 is formed on the substrate 6.
As shown in fig. 2, the shape of the opening on the screen printing plate 5 includes: any one of rectangle, circle, triangle and rhombus. Of course, the shape of the opening is not limited to the above-mentioned ones, and is not limited thereto.
Preferably, the printing system in this embodiment further includes: and the ink recovery module is used for recovering the ink on the surface of the screen printing plate 5. Specifically, after using the printing system that this embodiment provided to accomplish the 6 surperficial inkjet printings of base plate, can take out screen printing version 5 to wash screen printing version 5 surfaces, at this moment, chinese ink recovery module can handle from the 5 surperficial abluent liquid in screen printing version, in order to obtain chinese ink, and retrieve this chinese ink, in order to realize the recycle of chinese ink.
In summary, since the printing system provided by this embodiment includes not only the printing apparatus of embodiment 1, but also the screen printing plate 5, the vibrating ink ejected from the ink outlet of the resonant cavity 3 can be sprayed onto the substrate 6 to be formed with a film through the openings of the screen printing plate 5, so as to implement inkjet patterning, i.e. forming the patterned film layer 7 on the substrate 6. In addition, the printing system of the embodiment further includes an ink recycling module, which can recycle the ink sprayed on the surface of the screen plate 5, so as to reduce waste of the ink and save resources.
Example 3:
the present embodiment provides a printing method which can print using the printing system provided in embodiment 2. Specifically, the printing method of the present embodiment includes the steps of forming a plurality of patterned film layers 7 arranged in an array on the substrate 6; as shown in fig. 3 and 4, the step of forming a patterned film layer 7 on the substrate 6 includes:
s1, inputting ink into the resonant cavity 3.
Specifically, as shown in fig. 4, the black liquid in the ink storage chamber 1 is ink, and the ink storage chamber 1 delivers the ink into the resonant cavity 3 through the pipe 2.
S2, according to the type of the ink contained in the resonant cavity 3, the vibration frequency of the resonant cavity 3 is adjusted so that the vibration frequency of the resonant cavity 3 is equal to the natural frequency of the ink contained therein, so as to vibrate the ink in the resonant cavity 3.
Specifically, after the ink in the ink reservoir 1 is transferred into the resonant cavity 3, first, the identification unit identifies the type of the ink input into the resonant cavity 3; then, the obtaining unit obtains the natural frequency of the ink in the resonant cavity 3 according to a pre-stored relationship table of the natural frequencies of different types of ink and the type of the ink contained in the resonant cavity 3 identified by the identifying unit; finally, the adjusting unit adjusts the vibration frequency of the resonant cavity 3 according to the natural frequency of the ink acquired by the acquiring unit, so that the vibration frequency of the resonant cavity 3 is equal to the natural frequency of the ink contained therein.
S3, the ink outlet of the resonant cavity 3 is attached to the screen printing plate 5.
Specifically, as shown in fig. 4, when the vibrating ink is sprayed on the surface of the substrate 6, the ink outlet of the resonant cavity 3 needs to be attached to the screen printing plate 5, and at this time, the opening in the screen printing plate 5 is the ink outlet to form a chamber, so that the vibrating ink can be uniformly sprayed on the substrate 6 through the chamber. Meanwhile, it is easily understood that when the ink outlet of the resonant cavity 3 is attached to the screen printing plate 5, the distance from the ink outlet of the resonant cavity 3 to the substrate 6 is significantly smaller than the distance from the ink outlet of the resonant cavity 3 to the screen printing plate 5, and this arrangement enables the ejected ink to have the largest aftershock, so as to further ensure that the ink can be uniformly coated on the substrate 6.
S4, spraying the ink controlled by vibration onto the substrate 6 to be formed with a film through the ink outlet of the resonant cavity 3.
Specifically, the pressure valve applies pressure to the vibrating ink in the resonant cavity 3 to control the vibrating ink to sequentially pass through the ink outlet of the resonant cavity 3 and the opening of the screen printing plate 5 to be sprayed onto the substrate 6 to be subjected to film formation, so as to form the patterned film 7 on the substrate 6.
It should be noted that, in fact, the patterned film layer 7 is referred to as a patterned ink layer, that is, the patterned ink layer is irradiated by ultraviolet light or other laser means to chemically react and crosslink material molecules in the ink into bonds, so as to form the patterned film layer 7 on the substrate 6.
This completes the step of forming a patterned film layer 7 on the substrate 6.
The printing apparatus performs the above steps repeatedly to perform spraying one line at a time on the surface of the substrate 6, thereby completing the step of forming the plurality of patterned film layers 7 arranged in an array on the substrate 6.
It will be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
