Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and more specifically, to a transition chamber device for inkjet printing equipment and an inkjet printing device. Background Technology

[0002] Perovskite inkjet printing technology is an advanced manufacturing process that has emerged in recent years in fields such as solar cells, light-emitting diodes (LEDs), and photodetectors, attracting significant attention due to its ability to fabricate large-area, high-efficiency optoelectronic devices at relatively low cost. During the deposition of perovskite materials, to ensure material stability and device performance, the process typically requires an inert gas environment (such as nitrogen) to avoid the influence of reactive gases like oxygen and water vapor on the perovskite material. Therefore, perovskite inkjet printing equipment is often designed as a closed space with a nitrogen atmosphere.

[0003] However, existing perovskite inkjet equipment typically uses a door-opening method for material exchange (such as substrates and products). That is, when materials need to be transferred from the atmospheric environment to the nitrogen-atmosphere interior of the machine, or vice versa, the machine door must be opened to load or remove the materials. However, this material exchange method cannot effectively prevent external gases from disrupting the internal nitrogen atmosphere, and the diffusion of internal process solvent aerosols during the material exchange process cannot be properly addressed. Utility Model Content

[0004] The main objective of this invention is to provide a transition chamber device for inkjet printing equipment and an inkjet printing equipment, so as to solve the problem of damage to the internal environment of inkjet printing equipment during material exchange in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a transition chamber device for an inkjet printing equipment is provided. The transition chamber device is disposed on the machine base housing of the inkjet printing equipment, and the transition chamber device includes:

[0006] The transition box has a transition cavity, a first opening communicating with the operating cavity of the machine tool box, and a second opening communicating with the external environment.

[0007] At least two transition doors, at least one of which is openable and closable at the first opening, and at least another transition door is openable and closable at the second opening;

[0008] A conveying component is slidably disposed within the transition chamber to transfer materials between the operating chamber and the external environment;

[0009] A pressure regulating component, at least a portion of which is connected to the transition box and communicates with the transition cavity, and the pressure regulating component is used to regulate the pressure in the transition cavity.

[0010] Furthermore, the air pressure regulating component includes:

[0011] A gas delivery assembly, a part of which is connected to the transition chamber, is used to deliver a preset gas into the transition chamber.

[0012] The intake assembly has a portion that communicates with the transition chamber. The intake assembly is used to expel gas from the transition chamber, and the air supply assembly and intake assembly are used to regulate the pressure in the transition chamber.

[0013] Furthermore, the preset gas includes nitrogen.

[0014] Furthermore, another part of the suction assembly is connected to the recycling device of the inkjet printer to draw the gas in the transition chamber into the recycling device.

[0015] Furthermore, the gas intake assembly includes: a gas intake pipe, one end of which is connected to the transition chamber; a vacuum pump, the other end of which is connected to the intake port of the vacuum pump; and an exhaust pipe, one end of which is connected to the exhaust port of the vacuum pump, and the other end of which is connected to the recovery device, so as to send the gas in the transition chamber to the recovery device.

[0016] Furthermore, the bottom surface of the transition cavity has a slide rail, one end of which extends to the first opening and the other end of which extends to the second opening. The conveying component has a sliding member that cooperates with the slide rail so that the conveying component can slide on the slide rail.

[0017] Furthermore, the first opening and the second opening are located on opposite sides of the transition box, and the slide rail extends along the direction from the first opening to the second opening.

[0018] Furthermore, the transition hatch includes:

[0019] Door panel, pivotally connected to the transition box;

[0020] Multiple latches, each latch including a first locking element and a second locking element that are mutually locked, one of the first locking element and the second locking element being disposed on the door panel, and the other of the first locking element and the second locking element being disposed on the transition box.

[0021] Furthermore, the transition hatch also includes a seal, which is installed on the door panel and is used to seal the gap between the door panel and the transition box.

[0022] According to another aspect of the present invention, an inkjet printing apparatus is provided, comprising:

[0023] The machine tool housing has an operating cavity.

[0024] The aforementioned transition chamber device is embedded in the machine tool housing, and a portion of the transition chamber device is located inside the operating cavity.

[0025] Applying the technical solution of this utility model, the transition chamber device is installed on the machine base housing of the inkjet printer. The transition chamber device includes a transition housing, at least two transition doors, a conveying component, and a pressure regulating component. The transition housing has a transition cavity, a first opening communicating with the operating cavity of the machine base housing, and a second opening communicating with the external environment.

At least a portion of the pressure regulating component is connected to the transition housing and communicates with the transition cavity, and the pressure regulating component is used to regulate the pressure within the transition cavity.

[0026] By designing the transition chamber with a first opening and a second opening, and using a pressure regulating component to control the pressure within the transition chamber, it is beneficial to reduce the entry of external ambient gases into the operating chamber, thereby reducing the disruption of the nitrogen atmosphere inside the operating chamber by external gases. Simultaneously, the pressure regulating component also prevents gases from flowing from the operating chamber into the external environment, effectively preventing the diffusion of aerosols formed by process solvents within the operating chamber into the external environment, reducing hazards to operators, and also preventing pollution of the production environment.

[0036] To address the problem of material exchange disruption in existing inkjet printing equipment, this invention provides a transition chamber device and an inkjet printing device.

[0037] like Figures 1 to 3 As shown, the transition chamber device is installed on the machine base housing 10 of the inkjet printer. The transition chamber device includes a transition housing 20, at least two transition doors 30, a conveying component 40, and a pressure regulating component 50. The transition housing 20 has a transition cavity 21, a first opening 22 communicating with the operating cavity 11 of the machine base housing 10, and a second opening 23 communicating with the external environment. At least one transition door 30 is closably disposed at the first opening 22, and at least another transition door 30 is closably disposed at the second opening 23. The conveying component 40 is slidably disposed in the transition cavity 21 to transfer material between the operating cavity 11 and the external environment. At least a portion of the pressure regulating component 50 is connected to the transition housing 20 and communicates with the transition cavity 21, and the pressure regulating component 50 is used to regulate the air pressure in the transition cavity 21.

[0038] By configuring the transition chamber 20 with a first opening 22 and a second opening 23, and using a pressure regulating component 50 to control the pressure inside the transition chamber 21, it is beneficial to reduce the entry of external ambient gases into the operating chamber 11, thereby reducing the disruption of the nitrogen atmosphere inside the operating chamber 11 by external gases. Simultaneously, the pressure regulating component 50 also prevents gases inside the operating chamber 11 from flowing into the external environment, effectively preventing the diffusion of aerosols formed by process solvents within the operating chamber 11 into the external environment, reducing harm to operators, and also preventing pollution of the production environment. Furthermore, the transition chamber device of this invention also includes a conveying component 40, which is slidably disposed within the transition chamber 21 for easy operation by the operator.

[0039] Due to the cooperation between the transition chamber 20, at least two transition doors 30, the conveying component 40, and the pressure regulating component 50, the exchange of gases within the operating chamber 11 is effectively reduced. Before opening the transition doors 30 at the first opening 22 and the second opening 23, the transition chamber 21 is evacuated, and then pure nitrogen or other inert gases are added to the transition chamber 21 to ensure the purity of the internal environment. While adding pure nitrogen or other inert gases to the transition chamber 21, the pressure inside the transition chamber 21 can be adjusted to be greater than or equal to the external ambient pressure, or the pressure inside the transition chamber 21 can be adjusted to be greater than or equal to the pressure inside the operating chamber 11, thereby reducing the exchange of gases between the operating chamber 11 and the external environment.

[0040] Since the pressure regulating component 50 can effectively regulate the pressure and gas environment in the transition chamber 21, even if the transition chamber door 30 is briefly opened during the material exchange process, it can prevent active gases from the external environment from entering the operating chamber 11. At the same time, it can also prevent the aerosol formed by the process solvent in the operating chamber 11 from spreading to the external environment, reducing harm to operators and avoiding pollution to the production environment.

[0041] In some optional embodiments, the pressure regulating component 50 includes a gas supply assembly and a gas intake assembly. A portion of the gas supply assembly is connected to the transition chamber 21 and is used to supply a preset gas into the transition chamber 21. A portion of the gas intake assembly is also connected to the transition chamber 21 and is used to exhaust the gas from the transition chamber 21. The gas supply assembly and the gas intake assembly are used to regulate the pressure in the transition chamber 21. The gas supply assembly can supply a preset gas (such as high-purity nitrogen) into the transition chamber 21, while the gas intake assembly is used to exhaust the gas from the transition chamber 21, including possible active gases and process solvent aerosols. By precisely controlling the sequence of gas supply and intake, as well as the gas flow rate, the gas pressure in the transition chamber 21 can be effectively regulated, allowing it to reach a vacuum state or return to normal pressure when needed. Simultaneously, it ensures that the internal environment of the transition chamber 21 is always kept in the pure state required by the process, preventing external air from entering the operating chamber 11 and contaminating its internal environment, while also preventing internal gas from entering the external environment and contaminating it.

[0042] During material exchange, the gas supply and suction components operate in a cyclical manner to ensure that the gas in the transition chamber 21 is fully replaced, effectively purifying the gas environment within the transition chamber 21. This not only reduces the risk to operators but also minimizes damage to the internal environment of the operating chamber 11, thus improving process stability. For example, during material exchange, the suction component first evacuates the transition chamber 21, and then the gas supply component introduces a preset gas into the transition chamber 21. This cycle is repeated at least three times to ensure that the transition chamber 21 contains a pure, preset gas environment.

[0043] In some optional embodiments, the preset gas includes nitrogen. Nitrogen is an inert gas that does not readily react with most chemicals. Especially in perovskite inkjet printing, nitrogen effectively isolates reactive gases such as oxygen and water vapor, preventing interaction between reactive gases and the perovskite material. This avoids the problem of easy degradation or performance reduction of perovskite materials in environments with reactive gases. Filling the transition cavity 21 with nitrogen ensures that reactive gases are not introduced when materials enter or leave the operating cavity, maintaining the purity and stability of the internal process environment. Furthermore, since the operating cavity 11 is a nitrogen environment, filling the transition cavity 21 with nitrogen prevents the introduction of other gases into the operating cavity 11, which helps maintain the stability of the process environment. Of course, when the operating cavity 11 is in a different inert gas environment, the preset gas may include the same inert gas as that in the operating cavity 11.

[0044] In some alternative embodiments, another part of the suction assembly is connected to the recycling device of the inkjet printer to draw gas from the transition chamber 21 into the recycling device. The gas extracted from the transition chamber 21 by the suction assembly can be collected and filtered by the recycling assembly, allowing the pre-filtered gas to be reused. This not only reduces the impact of aerosols on the external environment but also avoids the waste of pre-filtered gas, effectively reducing production costs.

[0045] In some optional embodiments, the gas intake assembly includes a gas intake pipe, a vacuum pump, and an exhaust pipe. One end of the gas intake pipe is connected to the transition chamber 21; the other end of the gas intake pipe is connected to the intake port of the vacuum pump; one end of the exhaust pipe is connected to the exhaust port of the vacuum pump, and the other end of the exhaust pipe is connected to a recovery device to deliver the gas in the transition chamber 21 to the recovery device. The gas intake pipe is tightly connected to the transition chamber, ensuring efficient extraction of gas from the transition chamber. As the core component of the gas intake assembly, the vacuum pump can quickly reduce the gas pressure in the transition chamber 21, thereby rapidly extracting the gas (including any potentially present reactive gases, aerosols, etc.) and achieving rapid purification of the gas environment. This process creates conditions for the subsequent introduction of pure nitrogen, helping to quickly establish an oxygen-free, low-humidity inert gas environment and protecting the perovskite material from the damage of reactive gases. One end of the exhaust pipe is connected to the exhaust port of the vacuum pump, and the other end is connected to the recovery device. This means that the gas extracted from the transition chamber 21 will not be wasted, but will be sent to the recovery device for filtration to filter out the preset gas and reuse the filtered preset gas.

[0046] Optionally, the intake pipe of the intake assembly and the delivery pipe of the delivery assembly can share a common pipe to reduce the use of pipe layout. The specific pipe layout can be designed according to the actual situation.

[0047] In some alternative embodiments, please refer to Figure 3 The bottom surface of the transition cavity 21 has a slide rail 211, one end of which extends to the first opening 22 and the other end to the second opening 23. The conveying component 40 has a sliding element that cooperates with the slide rail 211, allowing the conveying component 40 to slide on the slide rail 211. During the conveying process, the material is placed on the conveying component 40, which slides along the slide rail 211, thereby making the material transfer more stable and reducing vibration and displacement of the material during the transfer process. By smoothly moving the conveying component 40 on a horizontal plane through the slide rail 211, the risk of material damage due to vibration or collision during the transfer process can be significantly reduced. Especially for materials such as perovskite materials that are sensitive to mechanical stress, the use of the slide rail 211 helps to ensure the integrity of the material during the transfer process and avoids the degradation of material properties due to physical damage.

[0048] Furthermore, the slide rail 211 allows the conveying component 40 to slide smoothly on it, from one side of the operating chamber 11 inside the machine to the side of the external environment, or vice versa. This sliding mechanism greatly simplifies the material transfer process. Operators only need to operate the conveying component 40 with one hand to complete the loading and unloading of materials, eliminating the need for laborious handling or complex manual transfer, thus improving the convenience and efficiency of operation.

[0049] In some alternative embodiments, such as Figures 1 to 3 As shown, the first opening 22 and the second opening 23 are located on opposite sides of the transition housing 20, and the slide rail 211 extends along the direction from the first opening 22 to the second opening 23. The second opening 23 faces the external environment, while the first opening 22 faces the operating cavity 11 inside the inkjet printer. The slide rail 211 extends along this direction, allowing the conveying component 40 to slide linearly between the outside and inside without turning or lifting, greatly simplifying the material transfer path and operation process, and improving the efficiency and smoothness of the transfer. Operators only need to push or pull the conveying component in the direction of the slide rail to complete the loading and unloading of materials, reducing the complexity of operation. Moreover, the linear design of the slide rail 211 simplifies the maintenance and cleaning process. The linear slide rail 211 is easier to clean and maintain than a complex three-dimensional structure, reducing the time and cost of equipment maintenance and ensuring the long-term stability and reliability of the equipment.

[0050] Furthermore, the design of the linear guide rail 211 enables the automation of material transfer within the transition box 20. By integrating sensors and drive devices, the automatic movement of the conveying component 40 on the guide rail 211 can be achieved, further improving production efficiency, reducing manual intervention, and driving inkjet printing equipment towards greater efficiency and intelligence.

[0051] In some alternative embodiments, such as Figures 1 to 3 As shown, the transition door 30 includes a door panel 31 and multiple latches. The door panel 31 is pivotally connected to the transition chamber 20. The latches include a first locking element 32 and a second locking element 33 that lock into each other. One of the first locking element 32 and the second locking element 33 is disposed on the door panel 31, and the other of the first locking element 32 and the second locking element 33 is disposed on the transition chamber 20. By providing multiple latches on the door panel 31, the transition door 30 can be reliably closed, preventing accidental opening during the printing process and improving equipment safety. The configuration of multiple latches ensures a reliable seal between the door panel 31 and the transition chamber 20, preventing gas leakage. This sealing is crucial during nitrogen purging and vacuum pump evacuation, ensuring that the pure nitrogen environment inside is not disrupted by external air, and also preventing internal process aerosols from diffusing to the outside, protecting the operating environment and personnel safety.

[0052] The door panel 31 is pivotally connected to the transition chamber 20, and the use of a latch makes the opening and closing of the transition door 30 safer and more controllable. Operators can safely control the opening and closing of the transition door 30 by locking and unlocking the latch, preventing gas leaks and operational interruptions caused by accidental opening of the transition door 30. At the same time, the fast-operation characteristic of the latch also improves the efficiency of material exchange and reduces the time required to open and close the door.

[0053] In addition, the distributed design of multiple latches ensures that the force for opening and closing the door is evenly distributed. Even when wearing protective gloves, operators can easily control the opening and closing of the transition door 30, making one-handed operation possible and improving the convenience and efficiency of operation, especially in production environments where frequent material exchanges are required.

[0054] In some alternative embodiments, the transition door 30 also includes a seal disposed on the door panel 31, which seals the gap between the door panel 31 and the transition chamber 20. The presence of the seal ensures that when the door panel 31 is closed, the gap between the door panel 31 and the transition chamber 20 is completely sealed, preventing external air or moisture from entering the transition chamber 21 and reducing disruption to the environment inside the transition chamber 21. Simultaneously, it also prevents leakage of internal aerosols or process gases, effectively preventing the diffusion of internal process solvent aerosols and reducing the risk of operators inhaling harmful gases.

[0055] In some alternative embodiments, the inkjet printing equipment includes a machine housing 10 and the aforementioned transition chamber device. The machine housing 10 has an operating cavity 11, and the transition chamber device is embedded in the machine housing 10, with a portion of the transition chamber device located within the operating cavity 11. By embedding the transition chamber device into the machine housing, the influence of the external environment on the operating cavity 11 can be effectively isolated, protecting the stability of the printing process and the print quality. Furthermore, the embedded design of the transition chamber device significantly improves the integration and space utilization of the equipment, making it suitable for various inkjet printing applications requiring a high-purity gas environment, such as electronic component printing, biochip printing, precision optical component manufacturing, and semiconductor material printing. This embedded design not only provides a stable and pure printing environment but also optimizes the spatial layout of the equipment, improves its overall performance and efficiency, reduces its footprint, and is suitable for use in space-constrained production environments and laboratories, thus enhancing the applicability and flexibility of the equipment.

[0056] In some alternative embodiments, please refer to Figure 1 and Figure 2 The inkjet printing equipment also includes a glove operating station module 60, which is mounted on the machine housing 10, and at least a portion of the glove operating station module 60 can enter or exit the operating cavity 11.
