Abstract
Description
Technical Field
[0001] The utility model relates to the field of battery production equipment, in particular to an inkjet printer. Background Art
[0002] An inkjet printer is a device that converts liquid ink into fine particles through a nozzle and sprays them onto a substrate. Inkjet printing technology is used in a variety of industrial applications, including printing posters, signs, textiles, labels, photos, and more of varying sizes. Currently, inkjet printing technology is also used to deposit thin-film resist patterns during the manufacturing process of electronic liquid crystal display panels, and is even used for decoration and seasoning in the food industry. In recent years, academia and industry have shown interest in the application of inkjet printing technology in the field of perovskite solar cells. The general chemical formula of lead halide perovskite is APbX3, where 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 received significant attention from the industry.
[0003] Inkjet printing deposition technology has advantages such as fine patterning, large-scale sizing, precise and controllable deposition volume, and high material utilization (nearly 100%). Currently, academic research on the deposition of perovskite films using inkjet printing technology has been conducted, but most of this research is based on small desktop inkjet printers (such as the SUSS LP50), which cannot meet the requirements of large-scale mass production research. Existing industrial inkjet printers are generally not developed to meet the personalized needs of perovskite photovoltaic research and development. They are either desktop R&D-type or 24-hour production-type equipment.
[0004] For the industrialization and research and development of perovskite photovoltaics, the existing technology has the following defects: First, the existing desktop research and development or 24-hour production equipment is not completely closed, and the solution method of perovskite thin films usually contains highly toxic substances, which endanger human health and environmental safety. Second, the equipment status 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 interior of the inkjet printing equipment, resulting in the internal atmosphere of the machine not being pure enough, and unable to meet the high cleanliness requirements during the manufacture of perovskite films. Third, the ink supply pipelines of existing 24-hour production equipment are usually 2-3 meters long, which not only increases the ink consumption during the research and development process, but also brings about 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 in photovoltaic cell production. Utility Model Content
[0006] The main purpose of the utility model 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.
[0007] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, an inkjet printer is provided, comprising: a machine housing, the interior of which is provided with an operating chamber; a glove operation station module, the glove operation station module being arranged on the machine housing, and at least a portion of the glove operation station module being capable of entering or exiting the operating chamber; a print head module, the print head module being arranged in the operating chamber; a transition bin module, the transition bin module being arranged on the machine housing, at least a portion of the transition bin module being capable of moving relative to the machine housing, and the transition bin module being capable of communicating with the outside of the machine housing and the operating chamber, respectively; and an ink bottle assembly, the ink bottle assembly being arranged on the print head module.
[0008] Furthermore, the inkjet printer further includes a gas purification module, at least a portion of which is disposed inside the operating chamber.
[0009] Furthermore, the gas purification module 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.
[0010] Furthermore, the inert gas source component can release at least one of nitrogen and argon, or the inert gas source component can release dry air.
[0011] Furthermore, the inkjet printer also includes an external exhaust module, at least a portion of which is arranged outside the machine box, and an air intake of the external exhaust module is arranged toward one end of the transition chamber module that is connected to the outside of the machine box.
[0012] Furthermore, the air intake of the external exhaust module is located above one end of the transition chamber module that is connected to the outside of the machine box.
[0013] Furthermore, the ink bottle assembly includes an ink bottle placement platform, the print head module has a mounting outer frame, and the ink bottle placement platform is arranged on the mounting outer frame.
[0014] Furthermore, the ink bottle placement table is made of metal or engineering plastic.
[0015] Furthermore, the inkjet printer also includes a substrate carrier, which is arranged in the operating chamber and located between the print head module and the glove operation station module.
[0016] Furthermore, the inkjet printer further comprises a motion control module, and at least the substrate carrier and the print head module are connected to the motion control module by signals.
[0017] Applying the technical solution of the present utility model, the inkjet printer in this application includes a machine housing, a glove operation station module, a print head module, a transition chamber module, and an ink bottle assembly.

[0018] When using the inkjet printer disclosed herein, the machine housing includes a receiving chamber, and the transition chamber module communicates with the exterior of the housing and the operating chamber. The cooperation between the transition chamber module and the receiving chamber effectively isolates the inkjet operating environment from the external environment. Specifically, when the printhead module operates within the operating chamber, or when highly toxic substances are generated during the perovskite thin film solution preparation process, the presence of the transition chamber module effectively isolates the operating chamber from the outside world, thereby ensuring the personal safety of the operator. Therefore, the provision of the transition chamber module in the present application not only facilitates the transfer of items between the outside world and the operating chamber, but also significantly reduces the leakage of harmful substances within the operating chamber, thereby improving the safety of the device. Furthermore, the inclusion of the glove operation station module allows operators to operate the interior of the operating chamber from the outside through the glove operation station module. Furthermore, since the ink bottle assembly is mounted on the printhead module, the length of the ink supply line to the printhead module is effectively reduced, thereby reducing ink consumption and the amount of residual ink in the ink supply line. Therefore, the inkjet printer disclosed herein effectively addresses the poor applicability of prior art inkjet printers for photovoltaic cell production. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this 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 meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.
[0026] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; 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 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 of 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 internal operating chamber; the glove operation station module 20 is mounted on the machine housing 10, and at least a portion of the glove operation station module 20 can enter or exit the operating chamber; the print head module 30 is disposed within the operating chamber; the transition chamber module 40 is mounted on the machine housing 10, and at least a portion of the transition chamber module 40 can move relative to the machine housing 10 and can communicate with the exterior of the machine housing 10 and the operating chamber respectively; and the ink bottle assembly is mounted on the print head module 30.
[0029] When using the inkjet printer described herein, since the machine housing 10 includes a storage chamber and the transition chamber module 40 is connected to the exterior of the machine housing 10 and the operating chamber, the transition chamber module 40 and the storage chamber cooperate to isolate the inkjet operating environment from the external environment. Specifically, when the printhead module 30 is operating within the operating chamber, or when highly toxic substances are generated during the perovskite thin film solution preparation process, the presence of the transition chamber module 40 effectively isolates the operating chamber from the outside world, thereby ensuring the personal safety of the operator. Therefore, the provision of the transition chamber module 40 in this application not only facilitates the transfer of items between the outside world and the operating chamber, but also significantly reduces the leakage of harmful substances within the operating chamber, thereby improving the safety of the device. Furthermore, the inclusion of the glove operation station module 20 allows operators to operate the interior of the operating chamber from the outside through the glove operation station module 20. Furthermore, since the ink bottle assembly is mounted on the printhead module 30, the length of the ink supply pipeline of the printhead module 30 can be effectively reduced, thereby reducing ink consumption and the amount of ink remaining 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 can be a cube, a cuboid or a cylinder. In addition, in the present application, the transition bin module 40 can be a drawer box provided on the machine box 10, and the drawer box can 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 further 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, if Figure 1 As shown, the inkjet printer further includes a gas purification module 60, at least a portion of which is disposed within the operating chamber. Since the print head module 30 typically employs a flash jetting method for inkjet printing during operation, ink droplets within the operating chamber, i.e., perovskite solution or organic amine salt droplets, will drift and disperse into other modules or components within the operating chamber, and at the same time, cause the internal atmosphere of the operating chamber to be impure and unable to meet the high cleanliness requirements for perovskite thin film manufacturing. Therefore, by providing the gas purification module 60, the internal environment within the operating chamber can be effectively purified, thereby ensuring that the working environment and cleanliness within the operating chamber meet production requirements, and the air humidity within the operating chamber can also 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 blower 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 blower 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 gases can also be mixed with dry air, thereby ensuring the working environment of the operating chamber while also being able to control the humidity in the operating chamber.
[0035] Specifically, if 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 intake of the external exhaust module 70 is disposed toward one end of the transition chamber module 40 that is in communication with the outside of the machine housing 10. In the present application, since the transition chamber module 40 is primarily used for transferring items between the outside world and the operating chamber, the gas within the operating chamber can enter the transition chamber module 40. When the operator opens the transition chamber module 40 and connects the transition chamber module 40 to the outside world, the gas entering the transition chamber module 40 from the operating chamber can be discharged to the outside world and may be inhaled by the operator. Therefore, the provision of the external exhaust module 70 can absorb the gas exhausted from the transition chamber module 40 at this time, thereby ensuring the safety of the external environment and the operator.
[0036] Preferably, the air intake of the external exhaust module 70 is located above the end of the transition chamber module 40 that connects to the exterior of the machine housing 10. This arrangement ensures that the external exhaust module 70 can more easily absorb gas. Furthermore, when the door needs to be opened for maintenance or other operations within the machine housing 10, the fan of the gas purification module 60 and the external exhaust module 70 automatically activate upon door opening, removing harmful substances from the machine interior. This avoids the technical drawback of existing solutions that require frequent door openings and can lead to exposure to 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, as Figure 2As shown, the inkjet printer further includes a substrate carrier 80, which is disposed within the operating chamber and located between the print head module 30 and the glove manipulation station module 20. This arrangement allows an operator to more easily operate other objects or structures within the operating chamber through the glove manipulation station module 20.
[0040] Alternatively, as Figure 2 As shown, the inkjet printer also includes a motion control module 90, and at least the substrate stage and the print head module 30 are signal-connected to the motion control module 90. Furthermore, in this application, a computer can be signal-connected to the motion control module 90. In other words, in this application, an operator can control the motion control module 90 via a computer, thereby controlling the print head module 30, the substrate stage, and other structures. Furthermore, in this application, there can be multiple motion control modules 90, and they can be signal-connected to different modules or components within the operating chamber.
[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0042] 1. Effectively solve the problem of poor applicability of inkjet printers in the existing technology when used in photovoltaic cell production;
[0043] 2. Simple structure and stable performance.
