Abstract

The application relates to a coating mechanism and a coating device. The coating mechanism comprises a coating frame, at least two lifting assemblies arranged on opposite sides of the coating frame along a first direction, and at least one coating assembly which is arranged between the lifting assemblies on the opposite sides and can be lifted along a third direction intersecting the first direction with the lifting assemblies. The coating assembly has two ends arranged oppositely along the first direction, and any end of the coating assembly is hinged to the corresponding lifting assembly. The coating device comprises a bearing mechanism and the above-mentioned coating mechanism. The coating mechanism can change the height position of the coating assembly by lifting the coating assembly with the lifting assemblies, so that different areas of the object to be coated can be coated. Since any end of the coating assembly is hinged to the corresponding lifting assembly, any end of the coating assembly can be moderately turned relative to the lifting assembly, so that the situation that the coating assembly cannot be lifted due to the different lifting rates of the two ends of the coating assembly is improved.

Description

Technical Field

[0001] This application relates to the field of coating technology, and in particular to a coating mechanism and coating apparatus. Background Technology

[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. Furthermore, 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] In the production process of perovskite solar cells, perovskite solutions need to be coated. How to improve coating stability and coating precision to achieve uniform film formation and ideal crystal quality, thereby improving the overall performance of the battery, remains a technical problem that urgently needs to be solved. Utility Model Content

[0004] Therefore, it is necessary to provide a coating mechanism and coating device to address the problems of poor coating stability and coating accuracy in existing coating mechanisms.

[0005] A coating mechanism includes: a coating rack; at least two lifting components disposed on opposite sides of the coating rack along a first direction, the first direction being the length direction of the coating mechanism; at least one coating component spanning between the lifting components located on opposite sides, and capable of moving up and down with the lifting components along a third direction intersecting the first direction; wherein the coating component has two ends disposed opposite to each other along the first direction, and any end of the coating component is hinged to the corresponding lifting component.

[0006] In the aforementioned coating mechanism, the coating component can be raised and lowered along with the lifting component to change the height position of the coating component, thereby enabling coating of different areas of the workpiece. Since either end of the coating component is hinged to the corresponding lifting component, either end of the coating component can be rotated appropriately relative to the lifting component. This improves the situation where the coating component cannot be raised or lowered due to different lifting rates at both ends of the coating component, resulting in better synchronization and smoothness of both ends of the coating component during the lifting process. This enhances the coating stability of the coating mechanism and helps to improve the coating accuracy and coating effect of the paint.

[0007] In some embodiments, the coating assembly includes a mounting beam and a coating head, the coating head being fixed to the bottom side of the mounting beam, and the two ends of the mounting beam along the first direction being hinged to the corresponding lifting assembly.

[0008] In some embodiments, the coating head is configured as an integral slot coating structure extending along the first direction.

[0009] In some embodiments, the coating mechanism further includes a hinge assembly, through which the end of the mounting beam is hinged to the lifting assembly.

[0010] In some embodiments, the hinge assembly includes a fixed seat, a movable seat, and a hinge column. The fixed seat is fixed to the lifting assembly, the end of the mounting beam is fixed to the movable seat, the movable seat is rotatably connected to the fixed seat via the hinge column, and the hinge column extends along a second direction intersecting the first direction.

[0011] In some embodiments, each of the lifting components includes a lifting plate, a driving component, a transmission component, and a guide component. The driving component is connected to the transmission component, the transmission component is fixedly connected to the lifting plate, the fixed seat is fixed to the lifting plate, and the guide component is connected to the lifting plate. Under the drive of the driving component, the transmission component drives the lifting plate to move up and down in the third direction, and drives the fixed seat to move up and down in the third direction. The guide component guides the lifting plate to move up and down.

[0012] In some embodiments, the coating rack includes a first crossbeam and at least two supports, the first crossbeam extending along the first direction, and each support being supported on opposite sides of the bottom of the first crossbeam along the first direction.

[0013] In some embodiments, the first beam and each of the supports are constructed as heat-resistant rigid columnar structures.

[0014] In some embodiments, the coating rack further includes an adjusting plate and a pushing member. The adjusting plate is correspondingly disposed to the support. A portion of the adjusting plate is fixedly connected to the support, and another portion of the adjusting plate is close to the outer surface of the first crossbeam. The pushing member extends out of the other portion of the adjusting plate along the first direction and then abuts against the outer surface of the first crossbeam. By adjusting the extension length of the pushing member in the first direction, the pushing force of the pushing member on the first crossbeam can be adjusted.

[0015] A coating apparatus includes: a support mechanism; and the coating mechanism described above, wherein the coating mechanism is movably disposed on the top side of the support mechanism.

[0016] In the aforementioned coating apparatus, the coating component can be raised and lowered along with the lifting component to change the height position of the coating component, thereby enabling coating of different areas of the workpiece. Since either end of the coating component is hinged to the corresponding lifting component, either end of the coating component can be rotated appropriately relative to the lifting component. This improves the situation where the coating component cannot be raised or lowered due to different lifting rates at both ends, resulting in better synchronization and smoothness of both ends of the coating component during the lifting process. This enhances the coating stability of the coating mechanism and helps to improve the coating accuracy and coating effect of the paint. Attached Figure Description

[0033] Please refer to Figure 1 In one embodiment, the coating mechanism includes a coating frame 100, at least two lifting components 200, and at least one coating component 300. Each lifting component 200 is disposed on opposite sides of the coating frame 100 along a first direction, which is the length direction of the coating mechanism. The coating component 300 spans between the lifting components 200 located on opposite sides and can move up and down with the lifting components 200 along a third direction intersecting the first direction. The coating component 300 has two ends disposed opposite to each other along the first direction, and any end of the coating component 300 is hinged to the corresponding lifting component 200.

[0034] It should be noted that the first direction is Figure 1 The X direction shown is the length direction of the coating mechanism; the third direction is... Figure 1 The Z direction shown is the height direction of the coating mechanism.

[0035] Here, the coating assembly 300 performs a coating operation, applying a coating material, which is a perovskite solution, to the workpiece to be coated. The lifting assemblies 200 located on opposite sides of the coating rack 100 along the first direction... Figure 1 When the device moves up and down in the Z direction as shown, it will drive the coating assembly 300 along the Z direction. Figure 1 The Z-direction lifting and lowering shown can change the height position of the coating assembly 300, thereby enabling coating of different areas of the workpiece.

[0036] In the aforementioned coating mechanism, the coating component 300 can be raised and lowered with the lifting component 200 to change the height position of the coating component 300, thereby enabling coating of different areas of the workpiece. Since either end of the coating component 300 is hinged to the corresponding lifting component 200, either end of the coating component 300 can be moderately rotated relative to the lifting component 200. This improves the situation where the coating component 300 cannot be raised or lowered due to the different lifting rates at both ends of the coating component 300, resulting in better synchronization and smoothness of both ends of the coating component 300 during the lifting process. This enhances the coating stability of the coating mechanism and helps to improve the coating accuracy and coating effect of the paint.

[0037] In the embodiments of this application, the coating rack 100 is a component used to provide installation space for each lifting assembly 200, and the coating rack 100 can adopt various structural forms. For example, the coating rack 100 is an integral structure, or the coating rack 100 can also be a split structure composed of multiple parts. The specific structural form of the coating rack 100 is not limited here.

[0038] In the embodiments of this application, the lifting assembly 200 is a component installed on the coating rack 100 and used to drive the coating assembly 300 to move up and down along a third direction. The lifting assembly 200 can adopt various structural forms. Each lifting assembly 200 is located on opposite sides of the coating rack 100 along the first direction, that is: the coating rack 100 along... Figure 1 At least one lifting component 200 is provided on each of the opposite sides in the X direction shown.

[0039] In the embodiments of this application, the coating assembly 300 is a component hinged to the lifting assembly 200 and used to apply coating material to the workpiece. The coating assembly 300 can adopt various structural forms. Either end of the coating assembly 300 is hinged to the corresponding lifting assembly 200, that is, either end of the coating assembly 300 is rotatably connected to the corresponding lifting assembly 200, so that either end of the coating assembly 300 can be rotated relative to the lifting assembly 200. For example, as... Figure 1 As shown, the coating rack 100 along Figure 1 A lifting assembly 200 is provided on each of the opposite sides in the X direction shown, and there is one coating assembly 300. Each end of the coating assembly 300 is hinged to a corresponding lifting assembly 200.

[0040] For details, please refer to Figure 2 The coating assembly 300 includes a mounting beam 310 and a coating head 320. The coating head 320 is fixed to the bottom side of the mounting beam 310. The two ends of the mounting beam 310 along the first direction are respectively hinged to the corresponding lifting assembly 200.

[0041] It is understood that the mounting beam 310 spans between the lifting components 200 located on opposite sides, and the mounting beam 310 has a first direction ( Figure 2 The two ends of the mounting beam 310 (shown in the X direction) are respectively set opposite each other, and either end of the mounting beam 310 is hinged to the corresponding lifting assembly 200.

[0042] The beneficial effect here is that the different sides of the mounting beam 310 are connected to the lifting assembly 200 and the coating head 320 respectively, which can make the coating assembly 300 and the lifting assembly 200 hinged, while not hindering the coating head 320 from applying paint, thus improving the space utilization of the coating assembly 300.

[0043] In the embodiments of this application, the mounting beam 310 is a component hinged to the lifting assembly 200, and the mounting beam 310 can adopt various structural forms. For example, the mounting beam 310 extends along a first direction, and the mounting beam 310 is a columnar structure, including shapes such as cylinders and prisms. The mounting beam 310 can be a solid columnar structure or a hollow columnar structure.

[0044] In the embodiments of this application, the coating head 320 is a component fixed to the bottom side of the mounting beam 310 and used to apply coating to the workpiece to be coated. The coating head 320 and the mounting beam 310 can be an integral structure with good integrity and high mechanical strength, which is convenient for quick assembly and disassembly; or, the coating head 320 and the mounting beam 310 can also be a separate structure, which is convenient for timely replacement and maintenance of the coating head 320.

[0045] For more specific details, please refer to Figure 2 The coating head 320 is configured as an integral slot coating structure extending along a first direction.

[0046] The beneficial effects here are: the coating head 320 is an integrated slit coating structure, which is easy to maintain a stable shape and size during long-term use, and has a wide coating area, which helps to improve coating accuracy and coating efficiency.

[0047] In the embodiments of this application, the coating head 320 can be integrally formed by casting or other methods. For example, the coating head 320 is integrally manufactured from high-rigidity steel and undergoes aging treatment to eliminate internal stress.

[0048] In the embodiments of this application, the number of coating heads 320 is not limited to one. When the number of coating heads 320 is at least two, each coating head 320 can be arranged side by side in the same direction.

[0049] Please refer to Figure 3 and Figure 4 The coating mechanism also includes a hinge assembly 400, through which the end of the mounting beam 310 is hinged to the lifting assembly 200.

[0050] The beneficial effect here is that by setting the hinge assembly 400, the mounting beam 310 of the coating assembly 300 can smoothly raise and lower the assembly 200 by hinge.

[0051] In the embodiments of this application, the hinge assembly 400 is a component used to connect the end of the mounting beam 310 with the lifting assembly 200. The hinge assembly 400 can adopt various structural forms. For example, the hinge assembly 400 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 assembly 400 is not limited herein.

[0052] For details, please refer to Figure 4 The hinge assembly 400 includes a fixed base 410, a movable base 420, and a hinge column 430. The fixed base 410 is fixed to the lifting assembly 200. The end of the mounting beam 310 is fixed to the movable base 420. The movable base 420 is rotatably connected to the fixed base 410 through the hinge column 430. The hinge column 430 extends along a second direction intersecting the first direction.

[0053] It should be noted that the second direction is Figure 4 The Y direction shown is the width direction of the coating mechanism. The hinge post 430 is along... Figure 4 Extending in the Y direction as shown, since the movable seat 420 is rotatably connected to the fixed seat 410 through the hinge column 430, the movable seat 420 can rotate around the hinge column 430, that is, the end of the mounting beam 310 can rotate around the hinge column 430.

[0054] The beneficial effects here are: the end of the mounting beam 310 of the coating assembly 300 can rotate around the hinge column 430, and either end of the coating assembly 300 can be moderately flipped relative to the lifting assembly 200. This improves the situation where the coating assembly 300 cannot be raised or lowered due to the different lifting rates at both ends of the coating assembly 300, and makes the synchronicity and smoothness of both ends of the coating assembly 300 better during the lifting process, thereby improving the coating stability of the coating mechanism.

[0055] In the embodiments of this application, the fixing seat 410 is a component used to fix the lifting assembly 200. The fixing seat 410 and the lifting assembly 200 are detachably connected. For example, the fixing seat 410 and the lifting plate 210 of the lifting assembly 200 are fixed with fasteners such as screws or bolts, so that the fixing seat 410 and the lifting assembly 200 are detachably connected. The fixing seat 410 can adopt various structural forms. For example, the fixing seat 410 is a rectangular, circular or other shaped block structure.

[0056] In the embodiments of this application, the movable seat 420 is a component used to fix the end of the mounting beam 310. The movable seat 420 and the end of the mounting beam 310 are detachably connected. For example, the movable seat 420 and the end of the mounting beam 310 are fixed by fasteners such as screws or bolts, so that the movable seat 420 and the end of the mounting beam 310 are detachably connected. The movable seat 420 can adopt various structural forms, for example, the movable seat 420 is a rectangular, circular or other block-shaped structure.

[0057] In the embodiments of this application, the hinge post 430 is a component for rotatably connecting the fixed seat 410 and the movable seat 420. The hinge post 430 can have various structural forms. For example, the hinge post 430 is a component that... Figure 4 The cylindrical structure extending in the Y direction shown can have a solid or hollow hinge column 430.

[0058] For more specific details, please refer to Figure 3 and Figure 2 Each lifting component 200 includes a lifting plate 210, a driving component 220, a transmission component 230, and a guide component 240. The driving component 220 is connected to the transmission component 230, the transmission component 230 is fixedly connected to the lifting plate 210, the fixed seat 410 is fixed to the lifting plate 210, and the guide component 240 is connected to the lifting plate 210. Under the drive of the driving component 220, the transmission component 230 drives the lifting plate 210 to rise and fall in a third direction, and drives the fixed seat 410 to rise and fall in a third direction. The guide component 240 guides the rise and fall of the lifting plate 210.

[0059] Understandably, driven by the drive component 220, the transmission component 230 moves and drives the lifting plate 210 along a third direction ( Figure 3 The lifting plate 210 is raised and lowered in the Z direction (as shown), and the fixed base 410 is raised and lowered in the third direction to change the height position of the coating assembly 300. The guide 240 can guide the lifting plate 210 in the third direction and prevent the guide 240 from tilting when it is raised and lowered in the third direction.

[0060] The beneficial effect here is that, driven by the drive component 220, the transmission component 230 drives the lifting plate 210 to rise and fall in the third direction, and drives the fixed seat 410 to rise and fall in the third direction, so as to change the height position of the coating component 300, and realize the coating of different areas of the workpiece. The structural design is simple and reasonable.

[0061] In the embodiments of this application, the lifting plate 210 is a component for providing installation space. The lifting plate 210 is constructed as a planar plate structure, and the outer contour of the planar plate structure can be rectangular, circular, elliptical or other shapes.

[0062] In the embodiments of this application, the drive member 220 is a component connected to the transmission member 230 and used to provide a power source. The drive member 220 can adopt various structures. For example, the drive member 220 is a motor or other drive structure with a power output shaft.

[0063] In the embodiments of this application, the transmission component 230 is a component that is connected to the driving component 220 and the lifting plate 210 in a transmission manner. The transmission component 230 can adopt various structures. For example, the transmission component 230 is a transmission screw with a lead screw nut. The lead screw nut is sleeved on the outside of the transmission screw. The transmission screw is connected to the driving component 220 and the lead screw nut is connected to the lifting plate 210. Under the drive of the driving component 220, the transmission screw rotates and drives the lead screw nut to rise and fall in a third direction, thereby driving the lifting plate 210 to rise and fall in a third direction.

[0064] In the embodiments of this application, the guide member 240 is a component that guides the lifting plate 210 in the third direction. The guide member 240 can adopt various structures. For example, the guide member 240 includes a guide rail and a slider that slides on the guide rail. The guide rail extends in the third direction and is fixed. The slider is fixedly connected to the lifting plate 210. When the lifting plate 210 moves in the third direction, the slider slides on the guide rail.

[0065] In the embodiments of this application, reference is made to Figure 3 Each lifting assembly 200 also includes a cylinder counterweight 250 and a pressure regulating valve 260. The cylinder counterweight is installed on the lifting plate of the lifting assembly 100. The cylinder counterweight balances unbalanced forces or torques in the mechanical system through counterweight. The pressure regulating valve is connected to the cylinder counterweight and is used to regulate the pressure of the cylinder within the cylinder counterweight. The cylinder counterweight 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.

[0066] Please refer to Figure 5 The coating rack 100 includes a first crossbeam 110 and at least two supports 120. The first crossbeam 110 extends along a first direction, and each support 120 is supported on opposite sides of the bottom of the first crossbeam 110 along the first direction.

[0067] It is understandable that the first crossbeam 110 is along the first direction ( Figure 5 Extending in the X direction (as shown), the first crossbeam 110 spans the top side of each support 120 located on opposite sides, the upper part of the lifting assembly 200 is connected to the first crossbeam 110, and the lower part of the lifting assembly 200 is connected to the support 120.

[0068] The beneficial effect here is that each support 120 is supported on the opposite sides of the bottom of the first crossbeam 110 along the first direction, so that the coating rack 100 is in the form of a gantry structure, which improves the structural stability of the coating rack 100 and is beneficial to the lifting stability of the subsequent lifting assembly 200.

[0069] In the embodiments of this application, the first crossbeam 110 is a component that spans the top side of each support 120 located on opposite sides. The first crossbeam 110 can adopt various structural forms. For example, the first crossbeam 110 extends along a first direction and is a columnar structure. The columnar structure includes shapes such as cylinders and prisms. The first crossbeam 110 can be a solid columnar structure or a hollow columnar structure.

[0070] In the embodiments of this application, the support 120 is a component that supports the bottom of the first crossbeam 110. Each support 120 is supported on opposite sides of the bottom of the first crossbeam 110 along a first direction, that is: the bottom of the first crossbeam 110 along... Figure 5 At least one support 120 is provided on each of the opposite sides in the X direction shown. The support 120 can take various structural forms. For example, the support 120 is a columnar structure, which includes shapes such as cylinders and prisms. The support 120 can be a solid columnar structure or a hollow columnar structure.

[0071] For a specific embodiment, please refer to Figure 1 The first crossbeam 110 and each support 120 are constructed as heat-resistant rigid columnar structures.

[0072] The beneficial effects here are: the first crossbeam 110 and each support 120 are heat-resistant and have a certain degree of hardness, are not easily deformed when heated and have a strong load-bearing capacity, which improves the structural stability of the coating rack 100 and is beneficial to the lifting stability of the subsequent lifting assembly 200.

[0073] In the embodiments of this application, the first crossbeam 110 and each support 120 are constructed as heat-resistant rigid columnar structures. Preferably, the first crossbeam 110 and each support 120 are made of marble, which has heat resistance and a certain degree of hardness. In other embodiments, the first crossbeam 110 and each support 120 may also be columnar structures made of different materials.

[0074] Further, please refer to Figure 5 The coating rack 100 also includes an adjusting plate 130 and a pushing member. The adjusting plate 130 is correspondingly arranged with the support 120. A part of the adjusting plate 130 is fixedly connected to the support 120, and the other part of the adjusting plate 130 is close to the outer surface of the first crossbeam 110. The pushing member extends out of the other part of the adjusting plate 130 along the first direction and then abuts against the outer surface of the first crossbeam 110. By adjusting the extension length of the pushing member in the first direction, the pushing force of the pushing member on the first crossbeam 110 can be adjusted.

[0075] It is understandable that, since a part of the adjusting plate 130 is fixedly connected to the support 120 and another part of the adjusting plate 130 is close to the outer surface of the first crossbeam 110, the pushing force of the pushing member on the first crossbeam 110 can be adjusted by adjusting the protrusion length of the pushing member in the first direction, thereby adjusting the levelness of the first crossbeam 110.

[0076] The beneficial effect here is that by adjusting the protrusion length of the pushing member in the first direction, the pushing force of the pushing member on the first crossbeam 110 can be adjusted, thereby adjusting the levelness of the first crossbeam 110, so that the first crossbeam 110 is kept as level as possible in the first direction, and improving the situation where the levelness of the first crossbeam 110 is affected by the bending deformation of the first crossbeam 110 due to its own weight.

[0077] In the embodiments of this application, the adjusting plate 130 is a component used to provide installation space. The adjusting plate 130 is constructed as a planar plate structure, and the outer contour of the planar plate structure can be rectangular, circular, elliptical, or other shapes. The number of adjusting plates 130 is not limited to one, and each adjusting plate 130 can be correspondingly provided with a support 120.

[0078] In the embodiments of this application, the pushing member is a component that extends out of another part of the adjusting plate 130 along the first direction and abuts against the outer surface of the first crossbeam 110. Preferably, the pushing member is a stud or screw, and the other part of the adjusting plate 130 has a screw hole for screwing with the stud or screw. The number of pushing members is not limited to one, and the pushing members can be arranged one-to-one with the screw holes opened on the adjusting plate 130.

[0079] Please refer to Figure 1 In one embodiment, the coating apparatus includes a support mechanism and the coating mechanism described above, wherein the coating mechanism is movably disposed on the top side of the support mechanism.

[0080] It should be noted that the support mechanism mainly serves to provide support and stability, offering a reliable working platform for the coating mechanism. The coating mechanism primarily performs the coating operation, applying the coating material to the workpiece. The coating mechanism is movably mounted on the top side of the support platform, allowing it to move within the platform according to the requirements of the coating process, thus enabling coating of different areas of the workpiece.

[0081] In the aforementioned coating apparatus, the coating component 300 can be raised and lowered with the lifting component 200 to change the height position of the coating component 300, thereby enabling coating of different areas of the workpiece. Since either end of the coating component 300 is hinged to the corresponding lifting component 200, either end of the coating component 300 can be moderately rotated relative to the lifting component 200. This improves the situation where the coating component 300 cannot be raised or lowered due to the different lifting rates at both ends of the coating component 300, resulting in better synchronization and smoothness of both ends of the coating component 300 during the lifting process. This enhances the coating stability of the coating mechanism and helps to improve the coating accuracy and coating effect of the coating material.

[0082] In the embodiments of this application, the supporting mechanism includes a drive unit, with two drive units respectively arranged at opposite ends of the coating mechanism. Each drive unit includes an air-bearing guide rail located on the top side of the supporting platform, and a drive component connected to the air-bearing guide rail. The coating mechanism is movably connected to the air-bearing guide rail, and the drive unit is connected to the coating mechanism to drive the coating mechanism to move along the air-bearing guide rail. The air-bearing guide rail is a precision guide rail system that utilizes the principle of gas static pressure to achieve contactless movement. High-pressure gas (usually air) is injected through an external air source (such as an air compressor) into the gap between the guide rail and the moving component, forming an extremely thin gas film (typically a few micrometers to tens of micrometers thick). This gas film completely isolates the moving component (such as the slider of the coating mechanism) from the surface of the air-bearing guide rail, preventing direct contact and thus achieving smooth, frictionless, and wear-free movement.

[0083] 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.

[0084] 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 utility model patent. 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.
