Description

Technical Field

[0001] This utility model relates to the field of flexible screen ink printing, specifically a flexible screen ink printing machine. Background Technology

[0002] With the development of technology, flexible screens are being used more and more widely in electronic products. In the manufacturing process of flexible screens, ink printing is an important step, usually using screen printing technology to print ink onto the substrate of the flexible screen.

[0003] Existing flexible screen ink printing machines, such as the screen printing machine proposed in patent application number "CN202322764733.X", use a worktable, printing frame, ink return blade, and ink scraper to spread ink evenly on the screen printing plate during the back-and-forth movement of the ink return blade.

[0004] However, existing technologies have drawbacks. The ink is directly added to the screen printing plate, then scraped evenly and flat before printing. When the ink is concentrated in a certain position on the screen, the number of scraping strokes required to spread the ink is large, which takes a long time and results in low printing efficiency. Therefore, a flexible screen ink printing machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a flexible screen ink printing machine to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A flexible screen ink printing machine, such as Figures 1-4 As shown, the device includes a base 1, with a bracket 3 and an electric slide 9 (model TOYO-GTH8) fixedly connected to the upper end of the base 1. The bottom of the bracket 3 is located on one side of the electric slide 9, and the upper end of the bracket 3 is located above the electric slide 9 to prevent the bracket 3 from affecting the operation of the electric slide 9. Both ends of the electric slide 9 are fixedly connected to mounting components, and a screen plate 14 for screen printing is snapped between the two sets of mounting components. The screen plate 14 is customized before printing and its size matches the printing machine. A doctor blade assembly is slidably connected to the electric slide 9. The doctor blade assembly scrapes and spreads the ink on the screen plate 14. An ink cartridge 4 is fixedly connected to the bracket 3. A stirring assembly is rotatably connected inside the ink cartridge 4. Multiple sets of ink outlet holes 21 are opened at the lower end of the ink cartridge 4. The multiple sets of ink outlet holes 21 are all located above the screen plate 14 and are arranged in a linear array.

[0024] The printing substrate for flexible screens is typically made of materials such as UTG and CPI. Inks are prepared using special polyester resin systems and nanomaterials, resulting in a thin ink film that meets the thickness requirements for flexible screen printing. The ink contains less than 700 ppm of chlorine (Cl), less than 700 ppm of bromine (Br), and less than 1100 ppm of total halogens, while also complying with environmental standards such as RoHS, REACH, and GB38507. The ink is printed ultra-thinly onto the flexible screen substrate using screen printing. This ultra-thin ink printing process promotes high-quality, high-efficiency, and environmentally friendly production of flexible screen equipment, meeting market and consumer demands. By controlling printing speed, printing pressure, and ink temperature, the ink achieves excellent adhesion and flow properties on the flexible substrate.

[0025] The ink cartridge 4 contains ink, and the stirring component stirs the ink inside the ink cartridge 4 to prevent ink sedimentation from affecting the printing uniformity. The ink drips through multiple sets of linearly arrayed ink outlet holes 21, which makes the ink added in a dispersed manner and prevents the ink from being concentrated in a certain position on the screen plate 14, thereby improving the ink scraping and spreading efficiency and thus improving the printing efficiency of the flexible screen.

[0026] like Figure 4As shown, the stirring assembly includes a motor 6 (model TF-N20F), which is fixed to the outer end of the ink cartridge 4. A rotating shaft 7 is fixed to the output end of the motor 6. The rotating shaft 7 is rotatably connected to the inside of the ink cartridge 4. A paddle 8 is fixed to the side wall of the rotating shaft 7. The paddle 8 is located inside the ink cartridge 4. An ink inlet pipe 5 is fixedly connected to the upper end of the ink cartridge 4. The ink inlet pipe 5 passes through the upper end of the bracket 3.

[0027] The output end of motor 6 drives the rotating shaft 7 to rotate, and the blades 8 on the side wall of the rotating shaft 7 rotate, causing the ink in the ink cartridge 4 to flow, preventing ink sedimentation. The ink surface has tension, and the ink will not flow out through the ink outlet hole 21 when there is no external pressure. When ink is filled into the ink cartridge 4 through the ink inlet pipe 5, the internal hydraulic pressure of the ink cartridge 4 will increase, thereby causing the ink to flow out through the ink outlet hole 21. The ink drips onto the screen due to gravity.

[0028] like Figures 1-3 As shown, the mounting assembly includes a fixing plate 15, which is fixed to one end of the electric slide table 9. A cylinder 16 (model AT91-100-2223) is fixed to the lower end of the fixing plate 15. A fixing frame 17 is fixed to the output end of the cylinder 16. An installation frame 18 is fixed to the side of the fixing frame 17. The two ends of the mesh plate 14 are respectively snapped into the two sets of installation frames 18.

[0029] Before printing, the two ends of the screen 14 are aligned with the two sets of mounting frames 18 and inserted for installation, so that the screen 14 is installed in the middle of the base 1. After the ink is scraped flat, the cylinder 16 drives the screen to descend through the fixing frame 17 and the mounting frame 18, so that the screen 14 fits with the flexible screen, which is convenient for printing.

[0030] like Figure 2 As shown, both ends of the two sets of mounting frames 18 are provided with sockets, and a card plate 19 is inserted into the socket. The card plate 19 abuts against the side of the mesh plate 14.

[0031] After the mesh plate 14 is installed, the clamping plate 19 is installed. The clamping plate 19 prevents the mesh plate 14 from shifting its position inside the mounting frame 18, or prevents the mesh plate 14 from detaching from the mounting frame 18. The clamping plate 19 has the function of limiting the position of the mesh plate 14.

[0032] like Figures 1-3 As shown, the ink scraping assembly includes a sliding seat 10, which is fixedly connected to the sliding end of the electric slide table 9. A drive plate 11 is fixedly connected to one side of the sliding seat 10, and a cylinder 12 (model TN10-30) is fixedly connected to the lower end of the drive plate 11. A scraper 13 is fixedly connected to the output end of the cylinder 12, and the scraper 13 cooperates with the scraping brush inside the screen plate 14.

[0033] The electric slide table 9 drives the slide seat 10 to slide, and the slide seat 10 drives the scraper 13 to slide through the drive plate 11 and the cylinder 12, so that the scraper 13 scrapes the ink inside the screen plate 14.

[0034] like Figure 1 and Figure 3 As shown, a transparent cover 2 is provided on the base 1, and a detector 20 is fixed inside the transparent cover 2.

[0035] The transparent cover 2 prevents dust and other impurities from affecting the ink printing of the flexible screen. In high temperature or humid environments, the ink of the ultra-thin flexible screen is prone to migration, which can lead to blurring of the printed pattern or fading of the color. The detector 20 includes a temperature detector and a humidity detector. Both of these detectors are existing technologies and will not be described in detail. They can detect the temperature and humidity inside the transparent cover 2, better monitor the printing environment, and improve the ink printing effect.

[0036] The working principle of the flexible screen ink printing machine provided by this utility model is as follows:

[0037] The screen plate 14 is installed on two sets of mounting components. The printing substrate of the flexible screen is placed on the upper end of the base 1, below the screen plate 14. The ink is dispersed and dripped onto the screen plate 14 through the ink cartridge 4. The electric slide table 9 controls the squeegee 13 to scrape the ink flat. Then, the cylinder 2 16 drives the screen plate 14 to adhere to the substrate. The output end of the cylinder 12 extends, driving the squeegee 13 to scrape the ink on the screen plate 14 again, printing the ink onto the flexible screen. The printed substrate is dried and cured under appropriate temperature and humidity conditions to ensure that the ink dries quickly and avoids damage to the flexible screen substrate.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
