[0002] Currently, perovskite materials are attracting widespread attention as a new generation of solar cell materials. Their unique photoelectric properties, characterized by high photogenerated carrier mobility and low exciton binding energy, enable solar cells based on this material to theoretically achieve photoelectric conversion efficiencies far exceeding those of traditional crystalline silicon cells. Perovskite materials can be prepared using low-temperature solution processes such as spin coating and blade coating, offering significant advantages over the high-temperature production processes of crystalline silicon cells, including simpler processes, lower energy consumption, and lower raw material costs.

[0003] Furthermore, due to the specific absorption spectrum inherent in perovskite structures, it is crucial to ensure material uniformity during coating; otherwise, poor solar cell conversion efficiency will result. Therefore, the perovskite coating production process demands extremely high standards in terms of both process technology and coating precision.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] Currently, perovskite materials are attracting widespread attention as a new generation of solar cell materials. Their unique photoelectric properties, characterized by high photogenerated carrier mobility and low exciton binding energy, enable solar cells based on this material to theoretically achieve photoelectric conversion efficiencies far exceeding those of traditional crystalline silicon cells. Perovskite materials can be prepared using low-temperature solution processes such as spin coating and blade coating, offering significant advantages over the high-temperature production processes of crystalline silicon cells, including simpler processes, lower energy consumption, and lower raw material costs.

[0040] Furthermore, due to the specific absorption spectrum inherent in perovskite structures, it is crucial to ensure material uniformity during coating; otherwise, poor solar cell conversion efficiency will result. Therefore, the perovskite coating production process demands extremely high standards in terms of both process technology and coating precision. However, existing coating equipment on the market cannot meet these high-precision requirements.

[0041] Based on the above considerations, and in order to solve the aforementioned problems, one or more embodiments of this application provide a coating apparatus, which includes a lifting device 100 and a coating device. The lifting device 100 drives the coating device to achieve high-precision displacement, thereby effectively improving the coating accuracy of the coating apparatus.

[0042] It is understood that the coating apparatus typically includes a coating rack and a coating head, the coating head being fitted onto the coating rack, the coating rack having two ends arranged opposite each other along a first direction, and either end of the coating rack being fitted onto at least one lifting device 100.

[0043] Thus, during the specific operation of the coating apparatus, the lifting device 100 can drive the coating rack to rise and fall, thereby achieving high-precision displacement of the coating rack. Furthermore, the coating rack can drive the coating head to rise and fall synchronously, thereby achieving high-precision coating operation.

[0044] More specifically, in this application, please refer to Figures 1 to 3. The lifting device 100 includes a machine body 10, a guide assembly 11, a lifting assembly 12, and a detection unit. The guide assembly 11 is movably mounted on the machine body 10 and connected to the coating device. The lifting assembly 12 is mounted on the machine body 10 and drivenly connected to the guide assembly 11. The lifting assembly 12 is configured to drive the guide assembly 11 to rise and fall relative to the machine body 10, and the guide assembly 11 drives the coating device to rise and fall synchronously.

[0045] Furthermore, the detection unit also includes a detection component 15 and a control component. The detection component 15 is coupled to the guide component 11 and configured to detect the position information of the guide component 11 in real time during the lifting process. The control component is communicatively connected to the detection component 15 and the lifting component 12. The control component is used to control the opening and closing of the lifting component 12 according to the position information detected by the detection component 15, so that the guide component 11 can drive the coating head to lift and lower to a preset position.

[0046] Understandably, during the specific operation of the coating apparatus, the lifting assembly 12 drives the guide assembly 11 to rise and fall, and the guide assembly 11 drives the coating rack and coating head to rise and fall synchronously. Simultaneously, the detection assembly 15 monitors the position information of the guide assembly 11 during the rising and falling process in real time, and transmits the detected position information to the control assembly. Subsequently, the control assembly determines the moving position of the guide assembly 11 based on the position information, and controls the lifting assembly 12 to stop operating when the guide assembly 11 drives the coating rack and coating head to a preset position, thereby achieving high-precision movement of the coating rack and coating head, and thus achieving high-precision coating operation.

[0047] In some embodiments, please refer to Figures 2 and 3. The lifting assembly 12 includes a servo motor 121 and a ball screw 122. The servo motor 121 is connected to the machine body 10. One end of the ball screw 122 is connected to the drive end of the servo motor 121, and the other end is connected to the guide assembly 11.

[0048] It is understandable that during the specific operation of the coating device, the ball screw 122 can convert the rotational motion generated by the servo motor 121 into linear motion to realize the lifting and lowering of the guide component 11, and the guide component 11 will drive the coating rack and coating head to lift and lower synchronously.

[0049] Simultaneously, the detection component 15 monitors the position information of the guide component 11 during the lifting process in real time, and transmits the detected position information to the control component. Subsequently, the control component determines the moving position of the guide component 11 based on the position information, and controls the lifting component 12 to stop operating when the guide component 11 drives the coating rack and coating head to a preset position, thereby achieving high-precision movement of the coating rack and coating head and thus realizing high-precision coating operation.

[0050] Furthermore, please refer to Figures 1 and 2. The detection component 15 is a grating ruler, and the grating ruler is communicatively connected to the servo motor 121.

[0051] Understandably, linear encoders can directly measure linear displacement, providing more accurate position information, thereby compensating for the backlash and errors of the transmission chain (such as lead screws, belts, etc.) and improving the overall accuracy of the system.

[0052] The core of the servo system for the movement of servo motor 121 is closed-loop control. The linear encoder, acting as a feedback device, can detect the actual position of the mechanical component in real time and convert it into an electrical signal, which is then fed back to the control component. The control component compares the preset position with the detected position information, generates an error signal, and calculates the control quantity using an algorithm (such as PID), adjusting the drive signal of servo motor 121 to drive the mechanical component's movement. Through closed-loop control, the system continuously adjusts until the detected position information matches the preset position, thereby achieving high-precision motion control.

[0053] In some embodiments, please refer to Figures 2 and 3. The guide assembly 11 includes a guide body 111, a linear guide rail 112 and a slider. The linear guide rail 112 is fitted onto the guide body 111, and the slider is fitted onto the body 10 and is movably connected to the linear guide rail 112.

[0054] During the process of the lifting assembly 12 driving the guide body 111 to rise and fall relative to the machine body 10, the guide rail and sliding parts cooperate to improve the smoothness and stability of the movement of the guide body 111, which in turn helps to achieve high-precision control of the lifting of the coating rack and coating head, and realize high-precision coating operation.

[0055] In some embodiments, please refer to Figures 2 and 3. The lifting device 100 also includes a brake (not shown), which is communicatively connected to a control component. The control component is used to control the brake to perform a braking operation on the lifting component 12 in response to a power failure signal.

[0056] Understandably, in the specific operation of the coating device, if a power failure occurs, the control component can respond to the power failure signal and control the braking component to brake the lifting component 12, so that the servo motor 121 stops, thereby preventing the guide component 11 from falling rapidly due to power failure and damaging the coating head during the lifting process.

[0057] In some embodiments, please refer to Figures 2 and 3, the lifting device 100 further includes a cylinder counterweight 13, which is coupled to the body 10 and is used to apply a force to the body 10 opposite to the direction of gravity.

[0058] Understandably, the cylinder counterweight 13 balances unbalanced forces or torques in the mechanical system through counterweight. The pressure regulating valve is connected to the cylinder counterweight 13 and is used to regulate the pressure within the cylinder. The cylinder counterweight 13 is typically controlled by a pneumatic system. For example, compressed air enters the cylinder, pushing the piston to move, thereby causing the counterweight to perform corresponding actions. By adjusting the pressure regulating valve, the output force and movement speed of the cylinder can be precisely controlled.

[0059] In some embodiments, as shown in Figures 1 and 2, the lifting device 100 further includes a flexible connector that is fitted onto the guide assembly 11 and is used to connect the coating head.

[0060] Specifically, the flexible connector is a hinge seat 14, which is fitted onto the guide assembly 11 and hinged to the coating device.

[0061] In the embodiments of this application, the hinge seat 14 is a component used to connect the end of the coating rack to the guide assembly 11. The hinge seat 14 can adopt various structural forms. For example, the hinge seat 14 is at least one of a single-axis hinge structure, a multi-axis hinge structure, and a spherical hinge structure. The specific type of the hinge seat 14 is not limited herein.

[0062] Specifically, please refer to Figure 4. The hinge seat 14 includes a fixed seat 141, a movable seat 142, and a hinge post 143. The fixed seat 141 is fixed to the guide assembly 11, and the end of the coating rack is fixed to the movable seat 142. The movable seat 142 is rotatably connected to the fixed seat 141 through the hinge post 143, and the hinge post 143 extends along a second direction intersecting the first direction.

[0063] It should be noted that, since the movable seat 142 is rotatably connected to the fixed seat 141 via the hinge column 143, the movable seat 142 can rotate around the hinge column 143, that is, the end of the coating rack can rotate around the hinge column 143.

[0064] In this application, the end of the coating frame of the coating device can rotate around the hinge column 143, and either end of the coating device can be moderately flipped relative to the guide component 11. This improves the situation where the coating device cannot be raised or lowered due to the different lifting rates at both ends of the coating device, and makes the synchronicity and smoothness of the two ends of the coating device better during the lifting process, thereby improving the coating stability of the coating equipment.

[0065] It is understood that the fixing base 141 is a component used to fix the guide assembly 11. The fixing base 141 and the guide assembly 11 are detachably connected. For example, the fixing base 141 and the guide assembly 11 are fixed by fasteners such as screws or bolts, so that the fixing base 141 and the guide assembly 11 are detachably connected. The fixing base 141 can adopt various structural forms. For example, the fixing base 141 is a rectangular, circular or other block-shaped structure.

[0066] Furthermore, the movable base 142 is a component used to fix the end of the coating rack. The movable base 142 and the end of the coating rack are detachably connected. For example, the movable base 142 and the end of the coating rack are fixed by fasteners such as screws or bolts, so that the movable base 142 and the end of the coating rack are detachably connected. The movable base 142 can adopt various structural forms. For example, the movable base 142 is a rectangular, circular, or other shaped block structure.

[0067] In the embodiments of this application, the hinge post 143 is a component used to rotatably connect the fixed seat 141 and the movable seat 142. The hinge post 143 can have various structural forms. For example, the hinge post 143 can be a cylindrical structure, a solid structure, or a hollow structure.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
