[0001] The present invention relates to an inkjet wafer circuit structure. More specifically, it is an inkjet wafer circuit structure that optimizes the configuration corresponding to the nozzles to improve the existing printing requirements. Background Art
[0002] Inkjet printing technology, commonly known as "Inkjet Printing", is a widely used printing technology. Its history can be traced back to the 1950s when the British company HP (Hewlett-Packard) invented inkjet printing technology. Since then, inkjet printing technology has developed rapidly, making inkjet printers the mainstream technology for home and commercial printing. Inkjet printers have many advantages, including: low cost, especially having an economic advantage in home and small business applications; high printing quality, capable of providing high-resolution and high-quality images, especially in the case of photos or pictures; convenient to use, inkjet printers are easy to install, and most inkjet printers can be printed through a computer or mobile device. When combined with office machines that have emerged in recent years with multi-functional capabilities (including fax, photocopying, scanning), the flexibility of office document operations can be quickly expanded.

Therefore, it is described in advance here.
[0040] Please refer to Figure 2A 、 Figure 2B 、 Figure 2C 、 Figure 2D 、 Figure 2E and Figure 2F , in the present invention, in order to achieve the aforementioned purpose of improving printing performance of the present invention, the inkjet chip circuit structure 300 proposed by the present invention is used to control an inkjet chip structure 200. Among them, the plurality of nozzles 210 form a nozzle double-row parallel structure as shown in Figure 2A 、 Figure 2B on the surface of the inkjet chip structure 200 (in this nozzle double-row parallel structure on the same Y-axis, it can spray twice from the left and right rows of nozzles 210 at the same printing point, making the printed color bright and full), such as the nozzle double-row staggered structure shown in Figure 2C 、 Figure 2D (this nozzle double-row staggered structure can make the printed color bright and full), or as shown in Figure 2E 、 Figure 2FThe single-row structure of the nozzle holes shown; among them, in the double-row parallel structure of the nozzle holes, the vertical distance between two longitudinally adjacent nozzle holes 210 in one row is 80 μm - 90 μm; in the double-row staggered structure, the vertical distance between two transversely staggered adjacent nozzle holes 210 is 40 μm - 45 μm, and in the single-row structure of the nozzle holes, the vertical distance between any two longitudinally adjacent nozzle holes 210 in this single row is 40 μm - 45 μm. In addition, in the above-mentioned embodiments, the width of the ink supply hole 200A is all 80 μm or more.
[0041] In order to effectively control the inkjet wafer structure 200 disclosed above, please refer to Figure 3 and Figure 4 , the present invention proposes a novel inkjet wafer circuit structure 300, which includes: a plurality of control modules 310 for controlling inkjet printing. The plurality of control modules 310 further have: an electrical control resistor R; a first power supply unit 311; a first power control unit 313, coupled to the first power supply unit 311, to control the opening and closing of the first power control unit 313 by the first power supply unit 311; an addressing unit 315, coupled to the first power control unit 313, to transmit an addressing signal to control the power supply required for inkjet printing; a second power control unit 317, coupled to the first power control unit 313, to control the opening and closing of the second power control unit 317 by the first power; a second power supply unit 316, coupled to the second power control unit 313, to supply the second power required for heating the ink; and a heating unit 312, coupled to the second power supply unit 316, to heat the ink required for inkjet printing. Wherein, when both the first power control unit 313 and the second power control unit 317 are turned on, the heating unit 312 starts to heat the ink required for inkjet printing by the second power, and the printing range of the inkjet wafer circuit structure control 300 is between 23900 μm - 27000 μm.
[0042] According to an embodiment of the present invention, the operating mechanism of the inkjet wafer circuit structure 300 disclosed above is as follows. When an addressing signal is input through the addressing unit 315 and a first power is input through the first power supply unit 311, and the first power is a relatively high voltage, the first power control unit 313 will be turned on. At the same time, the first power in the high voltage state will be transmitted to the second power control unit 317. And if the second power supply unit 316 also provides a second power at this time, and the second power is also a high voltage, then the second power control unit 317 will also be in the on state, so that the heating unit 312 obtains the energy to heat the ink and the inkjet printing signal, and starts to heat the ink, causing the ink to generate bubbles and be extruded to eject the ink from the nozzle 210. When the first power supply unit 311 does not provide the first power (or the first power is not a high voltage), then the first power or the addressing signal will not be transmitted to the second power control unit 317 through the first power control unit 313. And because the second power control unit 317 is electrically connected to the control resistor R, when the first power supply unit 311 does not provide the first power (or the first power is not a high voltage), or when the first power control unit 313 does not have an addressing signal, the second power supply unit 316 will not be turned on.
[0043] Please refer to Figure 4 , according to an embodiment of the present invention, the plurality of control modules 310 can form an array with two rows S1 and S2 in the inkjet wafer circuit structure 300, corresponding to more than 600 nozzles 210 contained in the inkjet wafer structure 200. This array is beneficial to the wiring layout that matches the arrangement space of the nozzles 210 on the inkjet wafer structure 200, so as to effectively improve the printing quality. In the embodiment of the present invention, S1 and S2 can respectively correspond to Figure 2A , Figure 2B the double-row side-by-side structure of the nozzles shown, thereby respectively controlling the nozzles 210 in the left and right rows, such as Figure 2C , Figure 2D the double-row staggered structure of the nozzles shown, thereby respectively controlling the nozzles 210 in the left and right rows, or such as Figure 2E , Figure 2FThe shown nozzle single-row structure is used to separately control the odd-numbered nozzles 210 from top to bottom (the 1st, 3rd, 5th,...) and the even-numbered nozzles 210 from top to bottom (the 2nd, 4th, 6th,...); it should be noted that the left and right two rows or the odd and even nozzles 210 corresponding to the above S1 and S2 are only examples and are not used to limit the aspects of the present invention. Those skilled in the art can adjust the nozzles 210 corresponding to S1 and S2 according to the above description and the application requirements after reading the specification of the present invention, or adjust the arrangement pattern of the control module 310 in the inkjet chip circuit structure 300, which is hereby described. According to one aspect of the present invention, in the arrays of the two rows of S1 and S2, corresponding first power supply units 311 will provide corresponding first power, so that the odd and even control of the two rows of nozzles 210 such as the above left and right double-row parallel structure and double-row staggered structure, and the single row of nozzles 120 in the nozzle single-row structure can be completed. For example, when the Am addressing unit 315 provides an addressing signal (for example, m = 15), Pn second power supply units 317 provide second power (for example, n = 20), and Sx first power supply units 313 provide first power (for example, x = 2), then 15 * 20 * 2 = 600 nozzles 210 can be controlled. Or, when m = 20, for example, n = 15, x = 2, 20 * 15 * 2 = 600 nozzles 210 can also be controlled. The description here is only an example, and those skilled in the art can adjust the structure of the present invention according to the manufacturing or application requirements to meet the actual industrial needs.
[0044] According to the content of the present invention, the inkjet chip circuit structure 300 further includes a first grounding unit 314 and a second grounding unit 318, which are respectively coupled to the first power supply control unit 313 and the second power supply control unit 317 to provide power protection for grounding the inkjet chip circuit structure 300.
[0045] According to the content of the present invention, the inkjet chip circuit structure 300 further includes an electrically controlled resistor R, which is coupled to the first power supply control unit 313 to adjust the magnitudes of the current and voltage in the first power according to the application requirements.
[0046] According to the content of the present invention, the resolution DPI (Dots Per Inch, the number of dots per inch) that the inkjet chip circuit structure 300 can correspond to ranges from 150 to 48000 DPI.
[0047] In summary, the main purpose of the present invention is to provide an inkjet chip circuit structure to control the corresponding inkjet chip structure. By optimizing the wiring of the inkjet chip circuit structure and cooperating with the spatial arrangement layout of the nozzles on the inkjet chip structure, the overall performance such as the printing color, resolution, printing range, printing speed, etc. is further improved to meet the increasingly stringent requirements of the market and meet the needs of industrial utilization.
