Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell production technology, and in particular to an inkjet printing system and a photovoltaic cell production line. Background Technology

[0002] Inkjet printing is a technology that sprays liquid ink, atomized into fine particles, onto a substrate through a nozzle. It is widely used in various industrial fields, such as for depositing resist patterns in the manufacturing of electronic liquid crystal display panels and in perovskite solar cells. The general chemical formula for lead halide perovskite is APbX3, where A represents a monovalent cation and X represents a monovalent halide anion. Among related technologies, inkjet printing deposition technology offers advantages such as fine patterning, large-size deposition, precise controllable deposition amount, and high material utilization (approaching 100%). In single-junction perovskite photovoltaics with perovskite as the active layer and perovskite-crystalline silicon tandem solar cells with perovskite as the top cell, inkjet printing deposition of perovskite thin films results in excellent film quality. After depositing the perovskite thin film on the solar cell substrate using inkjet printing equipment, post-processing steps are required, such as vacuum drying, flash evaporation, and degassing crystallization.

[0003] In related technologies, after the battery substrate is deposited in an inkjet printer, it is transferred out and exposed to air before entering a post-processing unit for subsequent steps. This process has the following drawbacks: First, the system consisting of the inkjet printer and the post-processing unit is not closed. Since highly toxic substances are often present in the solution-based perovskite thin film preparation process, the inkjet printer door is opened during the transfer of the perovskite substrate, causing these highly toxic substances to disperse, endangering the health of operators and the environment. Second, the perovskite thin film preparation process generally requires a low-humidity drying environment. To ensure this, current solutions involve building a drying room to control humidity throughout the laboratory. This solution is expensive and not conducive to large-scale, low-cost mass production of perovskite photovoltaic cells. Third, the battery substrate is exposed to high humidity air during the transfer process after perovskite film deposition. This increases the degree to which the perovskite film is affected by moisture during subsequent post-processing steps, negatively impacting battery quality.

[0004] Therefore, there is an urgent need for an inkjet printing system and a photovoltaic cell production line to solve the aforementioned problems in related technologies. Utility Model Content

[0013] The stage unit is configured to hold a substrate to be printed, and the printhead unit is used to inkjet print ink onto the substrate on the stage unit.

[0014] The transition device and the stage unit are spaced apart in the X direction.

[0015] As an optional solution to the inkjet printing system provided by this utility model, the inkjet printing device further includes a first operating glove;

[0016] The first operating glove is at least partially accessible inside the first sealed enclosure, and the first operating glove is configured to correspond to the printhead unit.

[0017] As an optional solution to the inkjet printing system provided by this utility model, the inkjet printing device further includes a second door that can be opened and closed on the first sealed box, and the first operating glove is connected to the second door.

[0018] As an optional solution to the inkjet printing system provided by this utility model, the inkjet printing device further includes a third door that can be opened and closed on the first sealed box.

[0019] The third door and the second door are respectively disposed on both sides of the first sealed box along the X direction, and the print head unit is located between the third door and the second door.

[0020] As an optional solution to the inkjet printing system provided by this utility model, the inkjet printing device also includes a second operating glove;

[0021] The second operating glove is at least partially accessible inside the first sealed enclosure, and the second operating glove is configured correspondingly to the platform unit.

[0022] As an optional solution to the inkjet printing system provided by this utility model, the post-processing device further includes a post-processing equipment and a third operating glove;

[0023] The post-processing equipment is located inside the second sealed box, and the third operating glove is at least partially able to enter the interior of the second sealed box. The third operating glove is configured correspondingly to the post-processing equipment.

[0024] As an optional solution to the inkjet printing system provided by this utility model, the post-processing device further includes a fourth door, which is closable and can be installed on the second sealed box.

[0025] As an optional solution to the inkjet printing system provided by this utility model, part of the transition chamber is located inside the first sealed box, and another part is located outside the first sealed box; the chamber door is connected to the end of the transition chamber away from the post-processing device.

[0026] As an optional solution to the inkjet printing system provided by this utility model, the end of the transition chamber is connected to the first door.

[0027] As an optional solution for the inkjet printing system provided by this utility model, the transition chamber is in the form of a polygon or a cylinder.

[0028] As an optional solution to the inkjet printing system provided by this utility model, the first door is rotatably connected to the first sealed box to open or close the first sealed box.

[0030] Secondly, a photovoltaic cell production line is provided, including the inkjet printing system described above.

[0031] The beneficial effects of this utility model are:

[0032] This invention provides an inkjet printing system and a photovoltaic cell production line using the inkjet printing system. The cell substrate is printed to form a deposited thin film in the first sealed chamber of the inkjet printing device. Then, the door of the transition chamber is opened, allowing the substrate to be transferred through the transition chamber to the second sealed chamber of the post-processing device for post-processing. By setting up the transition chamber, the first and second sealed chambers are sealed together, making the entire inkjet printing system a completely closed environment. That is, during the printing and post-processing processes, the substrate remains in a closed environment, preventing the leakage of toxic substances from the inkjet printing device, ensuring the health of operators and environmental safety, and improving the safety of equipment use. Furthermore, because the substrate is transferred through the transition chamber, it is not exposed to high humidity air, preventing moisture from affecting the film on the substrate, ensuring the quality of subsequent battery products, and improving battery conversion efficiency. Furthermore, since the inkjet printing unit, transition unit, and post-processing unit constitute a completely enclosed environment, it is only necessary to control this environment to meet low-humidity drying conditions. During the substrate transfer through the transition chamber, this enclosed environment remains unaffected, maintaining the low-humidity and dry production requirements. This effectively reduces costs compared to maintaining a low-humidity and dry environment throughout the entire laboratory housing the inkjet printing system. Moreover, by setting up the transition chamber, the substrate can be quickly transferred from the first enclosed chamber to the second enclosed chamber, effectively saving process time and increasing production cycle time.

[0033] When it is necessary to inspect and maintain the inside of the inkjet printer, the first door can be opened. During the opening process, the first door drives the entire transition device and the post-processing device to move synchronously. By setting the first roller at the bottom of the second sealed box, the post-processing device can roll and cooperate with the ground (such as the laboratory floor) through the first roller, reducing the resistance when the first door is opened and facilitating the inspection and maintenance of the inside of the first sealed box.

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0052] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0055] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0056] like Figure 1 As shown, this embodiment provides an inkjet printing system that can solve the technical problems of toxic substance leakage during production, high cost of maintaining the environmental conditions required for production, and the impact of moisture on perovskite films, and facilitates the internal maintenance of the inkjet printing system.

[0057] The inkjet printing system includes an inkjet printing unit 1, a transition unit 2, and a post-processing unit 3. The inkjet printing unit 1 includes a first sealed housing 11 and a first door 12 closable on the first sealed housing 11. The transition unit 2 includes a transition chamber 21 and a door 22 for opening or closing the transition chamber 21, the transition chamber 21 being sealed to the first door 12. The post-processing unit 3 includes a second sealed housing 31 sealed to the transition chamber 21, the second sealed housing 31 being communicative with the first sealed housing 11 via the transition chamber 21, and a first roller 32 being provided at the bottom of the second sealed housing 31.

[0058] In the inkjet printing system provided in this embodiment, the battery substrate is printed to form a deposited thin film within the first sealed chamber 11 of the inkjet printing device 1. Then, the door 22 of the transition device 2 is opened, allowing the substrate to be transferred through the transition chamber 21 to the second sealed chamber 31 of the post-processing device 3 for post-processing. By setting the transition chamber 21, the first sealed chamber 11 and the second sealed chamber 31 are sealed together, making the entire inkjet printing system a completely closed environment. That is, during the printing and post-processing processes, the substrate remains in a closed environment, preventing the leakage of toxic substances from the inkjet printing device 1, ensuring the health of operators and environmental safety, and improving the safety of equipment use. Furthermore, since the substrate is transferred through the transition chamber 21, it is not exposed to high-humidity air, preventing moisture from affecting the film on the substrate, ensuring the quality of subsequent battery products, and improving battery conversion efficiency. Furthermore, since the inkjet printing unit 1, the transition unit 2, and the post-processing unit 3 constitute a completely enclosed environment, it is only necessary to control this environment to meet low humidity drying conditions. During the transfer of the substrate through the transition chamber 21, this enclosed environment is unaffected, maintaining the low humidity and dryness production requirements. This effectively reduces costs compared to maintaining a low humidity and dry environment throughout the entire laboratory where the inkjet printing system is located. Moreover, by setting up the transition chamber 21, the substrate can be quickly transferred from the first sealed box 11 to the second sealed box 31, effectively saving process time and increasing production cycle time.

[0059] When it is necessary to inspect and maintain the inside of the inkjet printing device 1, the first door 12 can be opened. During the opening process, the first door 12 drives the entire transition device 2 and the post-processing device 3 to move synchronously. By setting the first roller 32 at the bottom of the second sealed box 31, the post-processing device 3 can roll and cooperate with the ground (such as the floor of a laboratory) through the first roller 32, reducing the resistance when the first door 12 is opened, and facilitating the inspection and maintenance of the inside of the first sealed box 11.

[0060] For example, the bottom of the second sealed enclosure 31 is provided with a plurality of first rollers 32, which can improve the stability of the post-processing device 3 when it rolls along the ground. For example, see Figure 1A first roller 32 is provided at each of the four corners of the bottom of the second sealed box 31. In other embodiments, the number and distribution of the first rollers 32 are not limited.

[0061] Specifically, the first sealed enclosure 11 is provided with a first door, and the first door 12 can be opened or closed. When the first door is opened, the operator can carry out inspection and maintenance inside the first sealed enclosure 11.

[0062] like Figure 1 As shown, the inkjet printing apparatus 1 also includes a printhead unit 13 and a stage unit 14. The printhead unit 13 is movably disposed within a first sealed housing 11 along the X direction, and the stage unit 14 is movably disposed within the first sealed housing 11 along the Y direction. The X and Y directions are arranged at an angle. Specifically, both the X and Y directions are horizontal and perpendicular to each other. More specifically, the first sealed housing 11 includes a first side plate 111 and a second side plate 112 connected vertically, wherein the X direction is parallel to the first side plate 111, and the Y direction is parallel to the second side plate 112. The stage unit 14 is configured to hold a substrate to be printed, and the printhead unit 13 is located above the stage unit 14 for inkjet printing the substrate on the stage unit 14. Taking perovskite photovoltaic cells as an example, the printhead unit 13 is equipped with a container for storing perovskite solution. The photovoltaic cell substrate is placed on the stage unit 14, and the stage unit 14 and the printhead unit 13 are controlled to move. The printhead unit 13 sprays ink in a flash spray manner to form a perovskite thin film on the substrate.

[0063] Specifically, the first sealed enclosure 11 is further provided with a first driving mechanism and a second driving mechanism. The first driving mechanism is used to drive the printhead unit 13 to move along the Y direction, and the second driving mechanism is used to drive the stage unit 14 to move along the X direction. For example, the first driving mechanism and the second driving mechanism can be linear driving mechanisms such as rod cylinders, rodless cylinders, hydraulic cylinders, electric push rods, and linear modules, etc., which are not limited here.

[0064] Furthermore, the transition device 2 and the stage unit 14 are spaced apart in the X direction, which can utilize the space on one side of the stage unit 14 in the X direction and avoid the first sealed box 11 being too large in the Y direction. The transition device 2 has a position directly opposite the stage unit 14 in the X direction. When the stage unit 14 moves to be directly opposite the transition device 2, the stage unit 14, the transition chamber 21, and the post-processing device 3 are arranged sequentially in the X direction, so that the substrate can be transferred in the X direction through the transition chamber 21 into the second sealed box 31 of the post-processing device 33.

[0065] See Figure 1The inkjet printing device 1 also includes a first operating glove 15. The first operating glove 15 is at least partially accessible inside the first sealed housing 11, and is correspondingly positioned to operate the printhead unit 13. The operator can wear the first operating glove 15 and reach into the first sealed housing 11 to perform operations, avoiding the leakage of toxic substances due to frequent opening of the inkjet printing device 1's door. Furthermore, since the first operating glove 15 corresponds to the printhead unit 13, it facilitates operation of the printhead unit 13. For example, the first operating glove 15 and the printhead unit 13 can be directly opposite each other in the X direction or offset by a certain distance (e.g., offset by 5cm to 20cm), as long as the operator can operate the printhead unit 13 after wearing the first operating glove 15. The specific position of the first operating glove 15 is not limited here.

[0066] Furthermore, the inkjet printing device 1 also includes a second door 16. The first sealed housing 11 is provided with a second doorway, and the second door 16 is closable on the first sealed housing 11 for opening or closing the second doorway. A first operating glove 15 is connected to the second door 16, resulting in a compact and reasonable layout. Specifically, the second door 16 is provided with a first glove hole, and the first operating glove 15 is connected to the edge of the first glove hole, allowing it to pass through the first glove hole and enter the interior of the first sealed housing 11.

[0067] See Figure 1 The inkjet printing device 1 also includes a third door 17. The first sealed housing 11 has a third door opening, and the third door 17 is closable on the first sealed housing 11 for opening or closing the third door opening. The third door 17 and the second door 16 are respectively located on both sides of the first sealed housing 11 along the X direction, and the printhead unit 13 is located between the third door 17 and the second door 16. When the second door 16 and / or the third door 17 are opened, the printhead unit 13 can be inspected, maintained, or have parts replaced. (Refer to...) Figure 1 The second door 16 allows for convenient operation of the right side of the printhead unit 13 when the second door 16 is opened, and the third door 17 allows for convenient operation of the left side of the printhead unit 13 when the third door 17 is opened.

[0068] See Figure 1The inkjet printer 1 also includes a second operating glove 18. The second operating glove 18 is at least partially accessible inside the first sealed housing 11. The second operating glove 18 is correspondingly positioned to the stage unit 14, allowing the operator to reach inside the first sealed housing 11 and operate the stage unit 14 after wearing the second operating glove 18, thus avoiding frequent opening of the inkjet printer 1's door and potential leakage of toxic substances. For example, the first sealed housing 11 has a second glove hole, and the second operating glove 18 is sealed to the edge of the second glove hole, allowing it to pass through the second glove hole into the first sealed housing 11. For example, the second operating glove 18 and the stage unit 14 can be directly opposite each other in the Y direction or offset by a certain distance (e.g., offset by 5cm to 20cm), as long as the operator can operate the stage unit 14 after wearing the second operating glove 18. The specific position of the second operating glove 18 is not limited here.

[0069] See Figure 1 The post-processing device 3 also includes a post-processing equipment 33 and a third operating glove 34. The post-processing equipment 33 is located inside the second sealed enclosure 31. The battery substrates transferred through the transition chamber 21 undergo post-processing through the post-processing equipment 33. The third operating glove 34 allows at least partial access into the second sealed enclosure 31 and is correspondingly positioned to work with the post-processing equipment 33. Wearing the third operating glove 34 allows operators to reach inside the second sealed enclosure 31 to operate on or near the post-processing equipment 33, enhancing safety.

[0070] For example, the post-processing equipment 33 may include one of a vacuum drying device, a flash evaporator, a vacuum crystallizer, or a near-infrared processor.

[0071] For example, the second sealed box 31 is provided with a third glove hole, and the third operating glove 34 is sealed and connected to the edge of the third glove hole, and can pass through the third glove hole to enter the interior of the second sealed box 31.

[0072] In this embodiment, the post-processing device 3 also includes a fourth door 35. The second sealed box 31 is provided with a fourth door. The fourth door 35 is closable on the second sealed box 31 and is used to cover or open the fourth door to facilitate the inspection and maintenance of the components inside the second sealed box 31.

[0073] For example, the fourth door 35 and the compartment door 22 are respectively located at both ends of the second sealed box 31 along the X direction, and the third operating glove 34 is located between the fourth door 35 and the compartment door 22.

[0074] See Figure 1In some optional embodiments, a portion of the transition chamber 21 is located inside the first sealed enclosure 11, and another portion is located outside the first sealed enclosure 11; the door 22 is connected to the end of the transition chamber 21 furthest from the post-processing device 3. That is, the transition chamber 21 is sealed through the first door 12, which can improve the connection stability between the transition chamber 21 and the first door 12, and the door 22 covers the opening at the end of the transition chamber 21 that extends into the first sealed enclosure 11, which can minimize the entry of toxic substances into the interior of the transition chamber 21. Exemplarily, the transition chamber 21 and the first door 12 can be welded together or connected by fasteners such as bolts and screws; there is no limitation here, as long as the two are sealed and fixed.

[0075] In some other alternative embodiments, see Figure 2 The end of the transition chamber 21 is sealed to the first door 12. At this time, the transition chamber 21 does not extend into the first sealed box 11, which can also achieve the connection of the post-processing device 3 and the inkjet printing device 1 into one unit.

[0076] Optionally, a mechanical gripper is provided inside the first sealed box 11, which can transfer the substrate from the first sealed box 11 to the second sealed box 31.

[0077] In some embodiments, such as Figure 3 As shown, at least one second roller 120 is provided at the bottom of the first sealed enclosure 11 to facilitate moving the inkjet printing device 1 to a designated location within the laboratory. When the inkjet printing device 1 is in operation, the second roller 120 is in a braked state, meaning it cannot be moved. The brake on the second roller 120 is released only when necessary, such as when it is necessary to move the inkjet printing device 1, allowing the second roller 120 to roll along the ground.

[0078] For example, four second rollers 120 are provided at the bottom of the first sealed box 11, and the four second rollers 120 are respectively located at the four corners of the first sealed box 11.

[0079] In other embodiments, such as Figure 1 and Figure 2 As shown, the second roller 120 may not be provided at the bottom of the first sealed box 11.

[0080] like Figures 4 to 9 As shown, the transition chamber 21 can be polygonal or cylindrical, as long as it provides a transfer channel. Examples of polygonal shapes include cubes, cuboids, hexagons, etc.

[0081] Specifically, in some embodiments, such as Figure 4 and Figure 5 As shown, the transition chamber 21 is rectangular in shape, and its opening is square or rectangular.

[0082] In some embodiments, such as Figure 6 and Figure 7 As shown, the transition chamber 21 is hexagonal in shape, and its opening is hexagonal.

[0083] In some embodiments, such as Figure 8 and Figure 9 As shown, the transition chamber 21 is cylindrical in shape, and its opening is circular.

[0084] Of course, the transition chamber 21 can also be in other shapes, which will not be listed here.

[0085] In some embodiments, the first door 12 is rotatably connected to the first sealed box 11 to open or close the first doorway of the first sealed box 11. When the first door 12 is opened or closed, the transition device 2 and the post-processing device 3 move synchronously as a whole, and the first roller 32 at the bottom of the post-processing device 3 rolls on the ground to reduce the resistance to opening the door.

[0086] In other embodiments, the first door 12 can also be slidably connected to the first sealed box 11 to slide open or close the first sealed box 11, which can also enable the internal inspection and maintenance of the inkjet printing device 1.

[0087] It is understandable that the second door 16, the third door 17, and the fourth door 35 can all be opened by rotating or sliding.

[0088] In this embodiment, the first door 12 and the third door 17 are located on the same side of the first sealed box 11, forming a double-door structure.

[0089] like Figure 1 As shown, a computer operating unit 19 and an inkjet printing operation screen 110 are also provided on the outside of the first sealed housing 11. The computer operating unit 19 can communicate with the first drive mechanism, the second drive mechanism, etc., as described above, to facilitate the control of the movement of the printhead unit 13 and the stage unit 14. The inkjet printing operation screen 110 can communicate with the printhead unit 13, and commands can be input through the inkjet printing operation screen 110 to make the printhead unit 13 operate according to the commands.
