Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a glass printer. Background Technology

[0002] In the traditional printing industry, inkjet printers are a common type of printing equipment. Inside the printer is an ink cartridge containing ink. The ink is delivered to the printhead through tubing. In an inkjet printer, the printhead contains many tiny nozzles, each corresponding to an ink channel. A heating element inside the printhead heats the ink, causing it to form tiny bubbles. As the ink bubbles form, they expand rapidly, propelling the ink out of the nozzles. The ejected ink droplets are precisely positioned at specific locations on the printing medium, forming images or text. However, the printhead operates under high temperature and pressure for extended periods, leading to severe nozzle corrosion and making it prone to ink splattering, thus affecting print quality.

[0029] This utility model proposes a glass printer.

[0030] Please see Figures 1 to 3 In one embodiment of the present invention, the glass printer includes a base 10 and an inkjet mechanism 20. The base 10 has a placement position for placing the glass to be printed. The inkjet mechanism 20 includes a moving module 21 and a printhead 22. The moving module 21 is disposed on the base 10 and located above the placement position. The printhead 22 includes a printhead 221 and a piezoelectric drive 222. The moving module 21 is connected to the printhead 221 in a driving connection. The printhead 221 has an inner cavity 221a and at least one ink inlet 221b communicating with the inner cavity 221a and a plurality of nozzles 221c. The piezoelectric drive 222 is installed in the inner cavity 221a and is used to push ink out of the nozzles 221c.

[0031] The base 10 has a placement position for placing the glass to be printed. The placement position is designed with a suitable support structure to ensure the glass remains stable during printing. The ink inlet 221b communicates with the inner cavity 221a for delivering ink to the nozzle 221c. The piezoelectric actuator 222 is installed inside the inner cavity 221a of the printhead 221 for propelling ink out of the nozzle 221c through the piezoelectric effect.

[0032] The moving module 21 is mounted on the base 10 and has a high-precision motion control system, enabling precise movement in the X, Y, and Z directions. This module is connected to the printhead 221, allowing the printhead 221 to move along a preset path during the printing process, thereby achieving printing on the glass surface.

[0033] The printhead 22 mainly consists of a printhead 221 and a piezoelectric drive unit 222. The printhead 221 has an inner cavity 221a connected to at least one ink inlet 221b to ensure a stable ink supply. The printhead 221 also has multiple evenly distributed nozzles 221c, which contribute to high-quality printing. The fine internal structure of the printhead 221 allows for precise control of the ink jet direction and speed, ensuring the clarity and detail of the printed image.

[0034] A piezoelectric actuator 222 is installed in the inner cavity 221a, utilizing the piezoelectric effect to achieve rapid and precise ink ejection. When voltage is applied to the piezoelectric actuator 222, it undergoes a minute deformation, thereby propelling ink out of the nozzle 221c. This driving method features fast response and high control precision, contributing to improved print quality and efficiency. The application of the piezoelectric actuator 222 makes the ink ejection process more precise and controllable, thus improving print quality.

[0035] Place the glass to be printed on the base 10. Activate the inkjet mechanism 20, causing the moving module 21 to move the printhead 221 across the glass surface. The piezoelectric actuator 222 generates a piezoelectric effect according to the printing command, pushing the ink in the inner cavity 221a through the nozzle 221c to form the desired pattern or text. After printing is complete, turn off the inkjet mechanism 20 and remove the printed glass.

[0036] This invention features an inkjet mechanism 20 with a piezoelectric drive 222 mounted on a moving module 21. The piezoelectric drive 222 is energized and deformed to drive ink through the nozzles 221c of the printhead 221 for precise ejection. The ink ejection process does not require heating, preventing the nozzles 221c of the printhead 221 from operating in a high-temperature environment, reducing the chance of printhead 221 corrosion. Furthermore, the room-temperature operating environment prevents ink droplets from splashing, thereby greatly improving printing quality.

[0037] In one embodiment, please refer to Figures 1 to 4 The piezoelectric drive 222 includes an adapter and a piezoelectric chip. The piezoelectric chip is installed in the inner cavity 221a and is arranged adjacent to the nozzle 221. The piezoelectric chip has multiple flow holes, each of which is connected to a corresponding nozzle 221c. The adapter is installed in the inner cavity 221a and is electrically connected to the piezoelectric chip. The piezoelectric chip is used to deform and push ink from the flow hole into the nozzle 221c for ejection after the adapter is energized.

[0038] Specifically, the piezoelectric drive unit 222 mainly consists of two parts: an adapter and a piezoelectric chip. The piezoelectric chip is precisely installed at a predetermined position in the inner cavity 221a, closely adjacent to the printhead 221, to facilitate rapid ink ejection. The surface of the piezoelectric chip has multiple flow holes, the number, size, and position of which are precisely calculated and designed to ensure that each flow hole corresponds one-to-one with the nozzle 221c on the printhead 221.

[0039] When the adapter is electrically connected to the piezoelectric chip, the chip is energized under the control of the adapter. Due to the piezoelectric effect, the chip undergoes a minute deformation. This deformation propels ink through the flow hole and into the adjacent nozzle 221c, thus achieving ink ejection. The entire process is responsive and highly accurate, meeting the demands of efficient printing. Furthermore, the adapter's mounting position and structure are matched to the piezoelectric chip, ensuring the stability and reliability of the chip during the driving process.

[0040] Furthermore, multiple flow holes are set in the piezoelectric chip, which correspond one-to-one with the nozzles 221c of the printhead 221. By precisely controlling the energization of each flow hole, the amount of ink ejected from each nozzle 221c can be controlled, thereby improving the inkjet accuracy of the inkjet mechanism 20 and thus enhancing the printing effect of the entire glass printer.

[0041] In one embodiment, please refer to Figures 1 to 4 The piezoelectric chip includes a body and multiple piezoelectric protrusions on the body. Each piezoelectric protrusion is embedded in a nozzle 221c. The body is electrically connected to the adapter. Each piezoelectric protrusion has a flow hole, and each piezoelectric protrusion is used to deform under current to push ink from the flow hole into the nozzle 221c for ejection. Alternatively, the end of the nozzle 221c away from the flow hole is designed with a flared shape.

[0042] Specifically, the body is made of high-quality piezoelectric material, possessing excellent piezoelectric effect and mechanical strength. Several piezoelectric protrusions are evenly distributed on the surface of the body; these protrusions are designed to achieve efficient and precise ink jet control.

[0043] Each piezoelectric protrusion is embedded in a specific position within an nozzle 221c, ensuring the stability and accuracy of ink ejection. These nozzles 221c are located within the printhead 221 assembly and fit tightly with the piezoelectric protrusions, forming a complete ejection system. The piezoelectric body and the adapter are connected electrically, facilitating the transfer of electrical energy to the piezoelectric protrusions to achieve their deformation function.

[0044] During the energizing process, each piezoelectric protrusion deforms according to the applied voltage signal, thereby propelling ink out of its corresponding nozzle 221c. This deformation is reversible; when the voltage signal disappears, the piezoelectric protrusion returns to its initial state, ready for the next ejection. By precisely controlling the magnitude and frequency of the voltage signal, the speed, direction, and volume of ink ejection can be adjusted to meet different printing needs.

[0045] The body is uniformly covered with multiple piezoelectric protrusions, each protrusion being columnar or conical in shape and of moderate height to accommodate the structure of the nozzle 221c. The position, size, and number of each piezoelectric protrusion are carefully designed to ensure the uniformity and stability of ink ejection.

[0046] The end of the nozzle 221c furthest from the flow hole has a gradually increasing cross-sectional diameter, forming an outwardly expanding shape. This flared design causes the fluid velocity to gradually decrease as it passes through the nozzle 221c, reducing pressure loss and thus improving spray efficiency. The flared nozzle 221c also facilitates the formation of a stable jet flow, ensuring good atomization during spraying and improving target coverage.

[0047] In one embodiment, please refer to Figures 1 to 3 The longitudinal cross-sectional shape of the piezoelectric chip is trapezoidal.

[0048] The trapezoidal cross-section has a longer upper base than lower base, and the two sides are slanted, resulting in a significant contraction trend in the vertical direction. This design helps improve the compressibility of the piezoelectric chip in the longitudinal direction, thereby enhancing its application in energy conversion and sensor fields.

[0049] The angle between the two sloping sides of the trapezoidal cross-section and the base can be adjusted according to actual application requirements to achieve different performance indicators. For example, increasing the angle can improve the longitudinal compression performance of the piezoelectric chip, but may also increase its lateral deformation; decreasing the angle is beneficial to reduce lateral deformation, but may reduce longitudinal compression performance.

[0050] In addition, the trapezoidal piezoelectric chip has a gap with the side wall of the inner cavity 221a, so that after the ink enters the flow hole of the piezoelectric chip, the excess ink will only flow on the outer side wall of the piezoelectric chip and will not stick to the side wall of the inner cavity 221a. This makes the use of the piezoelectric chip unaffected by ink sticking, thereby improving the inkjet effect of the inkjet mechanism 20.

[0051] In one embodiment, please refer to Figures 1 to 3 The glass printer also includes an ink tank 30, which is mounted on the moving module 21 and connected to the print head 22.

[0052] The ink tank 30 is designed with precision to ensure a continuous and stable ink supply during printing. The ink tank 30 is located on the moving module 21, a design that fully considers the printer's spatial layout and ease of operation during operation.

[0053] The ink tank 30 is connected to the printer head 22 via a connecting device that employs high-precision sealing technology to ensure ink purity and print quality. Furthermore, the ink tank 30's capacity is designed to meet the needs of extended printing sessions, reducing the frequency of ink changes and improving printing efficiency.

[0054] In the design of the moving module 21, considering the weight and balance of the ink tank 30, it is made of high-strength materials to ensure stability and reliability during movement. At the same time, the moving module 21 possesses excellent wear resistance and impact resistance, adapting to various complex working environments.

[0055] In one embodiment, please refer to Figures 1 to 3 The glass printer also includes a waste liquid storage box 40, which is located on the moving module 21 and below the printhead 221, for collecting waste ink ejected by the printhead 221.

[0056] The waste ink storage box 40 is mounted on the moving module 21, specifically positioned directly below the printhead 221. This allows all waste ink generated during the pre-printing test ink ejection process to flow smoothly into the waste ink storage box 40. The waste ink storage box 40 is designed to facilitate the collection and storage of waste ink, with a capacity sufficient to hold the waste ink generated during printing, preventing overflow or environmental pollution due to excessive waste ink. Furthermore, the waste ink storage box 40 is equipped with a level detection device. When the waste ink level in the storage box 40 reaches a set level, the level detection device will promptly issue an alarm, alerting the operator to handle the waste ink in a timely manner to prevent overflow.

[0057] In the design of the moving module 21, the installation position of the waste liquid storage box 40 has been carefully calculated to ensure that any movement of the printhead 221 during the printing process will not affect the normal operation of the waste liquid storage box 40. At the same time, the removal and installation of the waste liquid storage box 40 is simple, facilitating maintenance and cleaning. Through this design, the glass printer achieves efficient collection and treatment of waste liquid while ensuring print quality, reducing environmental pollution and improving the overall performance and lifespan of the printer.

[0058] In one embodiment, please refer to Figure 1 and Figure 2 The glass printer also includes a curing mechanism, which is fixed on the moving module 21 and is used to cure the ink-jet glass.

[0059] The base 10 has a placement position for placing the glass to be printed. The placement position is designed as a flat surface to ensure the stability of the glass during the printing process. The moving module 21 is located on the base 10 and its function is to move the print head 22 on the base 10. It is used to spray ink onto the glass surface. The curing mechanism is used to cure the ink after the print head 22 has printed the glass, to ensure the printing effect and ink adhesion.

[0060] The curing mechanism can be a hot air gun or a UV lamp. After inkjet printing on the glass by the print head 22, the hot air gun or UV lamp immediately cures the ink on the glass, allowing the ink to dry quickly, shortening the drying time after inkjet printing, and improving the production efficiency of glass printing.

[0061] In one embodiment, please refer to Figures 1 to 3 The base 10 is provided with a plurality of grooves 10a arranged at intervals. The plurality of grooves 10a are located at the placement position. Each groove 10a extends along the length direction of the base 10. A plurality of universal balls 10b are rotatably connected in each groove 10a. The plurality of universal balls 10b protrude out of the groove 10a.

[0062] Specifically, each groove 10a extends along the length of the base 10, forming a straight space to facilitate subsequent operations and connections. Multiple omnidirectional balls 10b are rotatably connected within each groove 10a. These omnidirectional balls 10b are precisely designed to rotate freely within the groove 10a to meet various usage requirements. Notably, all the omnidirectional balls 10b protrude beyond the groove 10a; this design reduces friction between the glass to be printed and the base 10, making it easier for the glass to slide on the base 10.

[0063] For further details, please refer to Figures 1 to 3 The surface of the omnidirectional ball 10b is provided with an elastic layer, which makes the omnidirectional ball 10b less likely to break when in contact with glass.

[0064] In one embodiment, the base 10 is provided with at least two positioning rods 11, which are located on both sides of the placement position and are spaced apart from a plurality of grooves 10a for positioning the glass to be printed.

[0065] The base 10 is ingeniously designed, incorporating at least two positioning rods 11. These positioning rods 11 are precisely positioned on both sides of the base 10's placement area. Each positioning rod 11 is made of high-precision material to ensure stability and durability. Multiple grooves 10a are evenly spaced between the two positioning rods 11, and these grooves 10a cooperate with the positioning rods 11 to form a unique positioning structure.

[0066] In this invention, the positioning rod 11 is spaced apart from multiple grooves 10a to precisely position the glass to be printed. During operation, the operator simply places the glass to be printed on the base 10, and the positioning rod 11 automatically inserts into the grooves 10a on both sides of the glass, thus achieving a stable fixation of the glass to be printed. This design not only improves the accuracy of positioning but also reduces errors during operation, providing a reliable foundation for subsequent printing processes.

[0067] Furthermore, the layout of the positioning rods 11 and the grooves 10a can be adjusted according to actual needs to meet the positioning requirements of glass of different sizes and shapes. In summary, the base 10 is provided with at least two positioning rods 11, which are located on both sides of the placement position and spaced apart from multiple grooves 10a, providing stable and precise positioning support for the glass printing process.

[0068] In one embodiment, please refer to Figures 1 to 3 The moving module 21 includes a first linear moving module and a second linear moving module. The first linear moving module is located on the base 10, and the second linear module is connected to the output end of the first linear moving module. The output end of the second linear moving module is connected to the machine head 22, and the moving direction of the first linear moving module is different from that of the second linear moving module.

[0069] The moving module 21 comprises the following core components: a first linear moving module and a second linear moving module. The first linear moving module is fixedly mounted on a base 10, which is made of high-strength metal to ensure the stability and durability of the entire module. The module internally uses precision linear guides and ball screws, ensuring smooth and accurate horizontal movement. The second linear moving module is cleverly designed to connect to the output end of the first linear moving module, forming a highly efficient energy transfer mechanism. This connection not only enhances the overall performance of the moving module 21 but also improves the system's working efficiency. The output end of the second linear moving module is tightly connected to the machine head 22, ensuring the stability of the machine head 22 during movement and thus guaranteeing machining accuracy.

[0070] It is worth mentioning that the movement direction of the first linear motion module is different from that of the second linear motion module. This design concept enables the motion module 21 to achieve independent movement control in two different directions, thereby providing greater flexibility and adaptability for the complex task of inkjet printing on glass by the print head 22 in two different directions.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
