Abstract
Description
Technical Field
[0001] The present invention relates to the field of battery production equipment, in particular to an inkjet printer. Background Art
[0002] An inkjet printing device is a device that turns liquid ink into fine particles and sprays them onto a substrate through a nozzle. Inkjet printing technology is used in various industrial applications, including printing posters, signs, textiles, labels, photos, etc. of different sizes. At present, inkjet printing technology is also used to complete the deposition of thin film resist patterns in the manufacturing process of electronic liquid crystal display panels, and is even used for decoration and condiments in the food industry. In recent years, academia and industry have become interested in the application of inkjet printing technology in the field of perovskite solar cells. The general chemical formula of lead halide perovskite is APbX3. Among them, A represents a monovalent cation and X represents a monovalent halogen anion. In recent years, single-junction perovskite photovoltaic technology with perovskite as the active layer and perovskite-crystalline silicon tandem cells with perovskite as the top cell have made significant progress and have received great attention from the industry.
[0003] Inkjet printing deposition technology has the advantages of fine patterning, large size, precise and controllable deposition amount, and high material utilization rate (close to 100%). At present, the academic community has carried out some research on the deposition of perovskite films based on inkjet printing technology, but most of them are based on small desktop inkjet printing equipment (such as SUSS LP50), which cannot meet the requirements of large-scale mass production research. Existing industrial inkjet printers are usually not developed for the personalized needs of perovskite photovoltaic research and development. They are either desktop research and development type or 24-hour production type equipment.
[0004] For the industrialization and development of perovskite photovoltaics, the existing technology has the following defects: First, the existing desktop R&D or 24-hour production equipment is not completely closed, and the perovskite film solution method preparation process usually contains highly toxic substances, which endangers human health and environmental safety. Second, the equipment state is usually maintained by flash spraying. However, during the flash spraying process, the ink droplets (perovskite solution or organic amine salt droplets) will drift and disperse into the inkjet printing equipment, resulting in the internal atmosphere of the machine being not pure enough, and unable to meet the high cleanliness requirements during the manufacture of perovskite films. Third, the ink delivery pipeline of the existing 24-hour production equipment is usually up to 2-3 meters long, which not only increases the ink consumption during the research and development process, but also brings the problem of ink residue in the pipeline. Fourth, the manufacture of perovskite films generally requires a low-humidity dry environment. The existing solution is to build a drying room to control the laboratory to maintain low humidity. However, this solution is expensive and is not conducive to large-scale and low-cost mass production of perovskite photovoltaic technology.
[0005] Therefore, there is a problem in the prior art that inkjet printers are poorly applicable when used for photovoltaic cell production. Summary of the invention
[0006] The main purpose of the present invention is to provide an inkjet printer to solve the problem of poor applicability of inkjet printers in the prior art when used for photovoltaic cell production.

[0014] Furthermore, the ink bottle placement table is made of metal or engineering plastics.
[0015] Furthermore, the inkjet printer also includes a substrate carrier, which is arranged in the operating chamber, and the substrate carrier is located between the print head module and the glove operation station module.
[0016] Furthermore, the inkjet printer also includes a motion control module, and at least the substrate carrier and the print head module are connected to the motion control module by signals.

That is to say, when the print head module is working in the operating chamber or when highly toxic substances are produced during the preparation process of the perovskite thin film solution method, the existence of the transition chamber module can effectively ensure that the operating chamber is isolated from the outside world, thereby ensuring the personal safety of the staff. Therefore, the provision of the transition chamber module in the present application can not only realize the transfer of items between the outside world and the operating chamber, but also greatly reduce the leakage of harmful substances inside the operating chamber, thereby improving the safety performance of the equipment. In addition, since there is a glove operation station module, the operator can operate the inside of the operating chamber through the glove operation station module from the outside.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.
[0027] In order to solve the problem of poor applicability of inkjet printers in the prior art when used for photovoltaic cell production, the present application provides an inkjet printer.
[0028] like Figure 1 and Figure 2 As shown, the inkjet printer in the present application includes a machine housing 10, a glove operation station module 20, a print head module 30, a transition chamber module 40 and an ink bottle assembly. The machine housing 10 has an operating chamber inside; the glove operation station module 20 is arranged on the machine housing 10, and at least a part of the glove operation station module 20 can enter or exit the operating chamber; the print head module 30 is arranged in the operating chamber; the transition chamber module 40 is arranged on the machine housing 10, and at least a part of the transition chamber module 40 can move relative to the machine housing 10, and the transition chamber module 40 can be connected to the outside of the machine housing 10 and the operating chamber respectively; the ink bottle assembly is arranged on the print head module 30.
[0029] When using the inkjet printer in the present application, since the machine housing 10 has a accommodating chamber and the transition chamber module 40 can be connected to the outside of the machine housing 10 and the operating chamber, the inkjet working environment can be isolated from the external environment through the cooperation of the transition chamber module 40 and the accommodating chamber. That is to say, when the print head module 30 is working in the operating chamber or when highly toxic substances are produced during the preparation process of the perovskite thin film solution method, the existence of the transition chamber module 40 can effectively ensure that the operating chamber is isolated from the outside world, thereby ensuring the personal safety of the staff. Therefore, in the present application, the provision of the transition chamber module 40 can not only realize the transfer of items between the outside world and the operating chamber, but also greatly reduce the leakage of harmful substances inside the operating chamber, thereby improving the safety performance of the equipment. In addition, since there is a glove operation station module 20, the operator can operate the inside of the operating chamber through the glove operation station module 20 from the outside. At the same time, since the ink bottle assembly is arranged on the print head module 30, the length of the ink supply pipeline of the print head module 30 can be effectively reduced, thereby reducing the consumption of ink and reducing the residual amount of ink in the ink supply pipeline. Therefore, the inkjet printer in the present application effectively solves the problem of poor applicability of inkjet printers in the prior art when used for photovoltaic cell production.
[0030] Optionally, the shape of the transition bin module 40 may be a cube, a cuboid or a cylinder. In addition, in the present application, the transition bin module 40 may be a drawer box disposed on the machine box 10, and the drawer box may serve as an intermediate structure for transferring items between the operating chamber and the outside world.
[0031] Preferably, in the present application, a printing operation display screen and a computer can be provided on the outside of the machine housing 10. The printing operation display screen is connected to the computer, and the computer can be connected to the structure signal of the print head module 30 and the like inside the machine housing 10.
[0032] Specifically, Figure 1 As shown, the inkjet printer further includes a gas purification module 60, at least a portion of which is disposed inside the operating chamber. Since the print head module 30 is generally used to spray ink in a flash jetting manner during operation, the ink droplets in the operating chamber, i.e., the perovskite solution or organic amine salt droplets, will drift and disperse into other modules or components in the operating chamber and at the same time cause the internal atmosphere of the operating chamber to be not pure enough, and cannot meet the high cleanliness requirements during the manufacture of the perovskite film. Therefore, by providing the gas purification module 60, the internal environment of the operating chamber can be effectively purified, thereby ensuring that the working environment and cleanliness of the operating chamber can meet the production requirements, and at the same time, the air humidity in the operating chamber can be adjusted.
[0033] Optionally, the gas purification module 60 includes at least one of an inert gas source component, a molecular sieve, a purification column, a fan component, and an organic solvent adsorption component. In a specific embodiment of the present application, the gas purification module 60 includes an inert gas source component, a molecular sieve, a purification column, a fan component, and an organic solvent adsorption component.
[0034] Optionally, the inert gas source assembly can release at least one of nitrogen and argon, or the inert gas source assembly can release dry air. Of course, in the present application, separate nitrogen and argon can also be mixed with dry air, so as to ensure the working environment of the operating chamber while also being able to control the humidity in the operating chamber.
[0035] Specifically, Figure 1 As shown, the inkjet printer further includes an external exhaust module 70, at least a portion of which is disposed outside the machine housing 10, and an air inlet of the external exhaust module 70 is disposed toward one end of the transition chamber module 40 that is connected to the outside of the machine housing 10. In the present application, since the transition chamber module 40 is mainly used for transferring items between the outside and the operating chamber, the gas in the operating chamber can enter the transition chamber module 40, and when the operator opens the transition chamber module 40 and connects the transition chamber module 40 to the outside, the gas entering the transition chamber module 40 from the operating chamber can be discharged to the outside and may be inhaled by the operator. Therefore, the external exhaust module 70 can absorb the gas discharged from the transition chamber module 40 at this time, thereby ensuring the safety of the external environment and the operator.
[0036] Preferably, the air inlet of the external exhaust module 70 is located above one end of the transition chamber module 40 that is connected to the outside of the machine box 10. This arrangement ensures that the external exhaust module 70 can absorb the gas more easily. And when it is necessary to open the door to perform internal maintenance and other operations of the machine box 10, the fan of the gas purification module 60 and the external exhaust module 70 will automatically start at the moment of opening the door, and the harmful substances inside the machine can be extracted, avoiding the technical defect of the prior art solution that the machine door needs to be opened frequently to operate and cause contact with toxic substances.
[0037] Furthermore, in the present application, the interior and exterior of the machine housing 10 can be designed as an integrated seamless structure, thereby isolating the interior and exterior of the machine housing 10 and preventing harmful substances from leaking out.
[0038] Optionally, the ink bottle assembly includes an ink bottle placement platform, the print head module 30 has a mounting frame, and the ink bottle placement platform is arranged on the mounting frame. In addition, the ink bottle placement platform is made of metal or engineering plastic.
[0039] Alternatively, if Figure 2As shown, the inkjet printer further includes a substrate carrier 80, which is disposed in the operating chamber and between the print head module 30 and the glove operation station module 20. This arrangement enables the operator to more easily operate other items or structures in the operating chamber through the glove operation station module 20.
[0040] Alternatively, if Figure 2 As shown, the inkjet printer further includes a motion control module 90, and at least the substrate stage and the print head module 30 are connected to the motion control module 90 by signal. Moreover, in the present application, a computer can be connected to the motion control module 90 by signal. That is, in the present application, an operator can control the motion control module 90 through a computer, thereby realizing control of structures such as the print head module 30 and the substrate stage. Moreover, in the present application, the motion control module 90 can be multiple and can be connected to structures such as different modules or components in the operating chamber by signal.
