Description

[0001] This application is a divisional application of the original application with application number 202311531655.7 (filed on November 17, 2023, entitled "A Coating Auxiliary Balancing Device and Control Method Thereof"). Technical Field

[0002] This invention relates to the field of coating equipment technology, and in particular to a coating auxiliary balancing device. Background Technology

[0003] Coating equipment is an important type of industrial machinery used to uniformly coat various materials, such as paints, inks, adhesives, and films, onto the surface of a substrate to meet the production needs of different industries. With the rapid development of new energy sources, perovskite solar cells have gained widespread application due to their advantages such as high photoelectric conversion efficiency, long lifespan, and low manufacturing cost. In the fabrication process of perovskite solar cells, the coating component of the coating equipment applies a perovskite solution to a conductive substrate. The uniformity and thickness of the perovskite solution coating both affect the photoelectric conversion efficiency of the perovskite solar cell. Therefore, the coating equipment that mounts the coating component is a high-precision device, and its precision significantly impacts the photoelectric conversion efficiency of the perovskite solar cell. In existing technologies, the coating component is mounted on a support, and the parallelism between the coating component and the conductive substrate is maintained by adjusting the height of both ends of the support. During adjustment, a height difference occurs between the two ends of the support, causing a change in the mounting spacing at both ends. It is necessary to adjust the distance between the side plates at both ends of the support to keep the mounting spacing constant. Such adjustment steps are complex, leading to inconvenience in operation. The need for frequent adjustments to the coated parts significantly reduces production efficiency and can also cause instability in the machine frame structure, affecting coating quality. How to quickly adjust the parallelism between the coated parts and the conductive substrate is a pressing problem that needs to be solved. Summary of the Invention

[0033] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided to make the invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0034] The terms used to express position and direction in this invention are illustrated with reference to the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this invention.

[0035] refer to Figure 1 , Figure 4 This invention provides a coating auxiliary balancing device 100, comprising: a frame 1, a support 2, a drive assembly 4, and a balancing assembly 5, and may further include a support assembly 3. The coating auxiliary balancing device 100 of this application can be used in various coating equipment. This application uses the coating auxiliary balancing device 100 in a perovskite coating equipment as an example for illustration, where the perovskite coating equipment is used to produce perovskite solar cells.

[0036] Specifically, the frame 1 mainly serves a supporting function, and other components are mounted on the frame 1. The frame 1 is preferably made of a rigid material, such as stainless steel, and has a large thickness to ensure that it has sufficient structural strength and prevents deformation during use.

[0037] Reference Figure 6The frame 1 may include a first side plate 11 and a second side plate 12, which are arranged opposite to each other. The larger area side of the first side plate 11 and the larger area side of the second side plate 12 face each other, and preferably, the larger area side of the first side plate 11 and the larger area side of the second side plate 12 are arranged relatively parallel. A first structural plate 14 may be provided on the first side plate 11, which is made of an elastomeric material. An elastomeric material is a material that can deform under stress but can return to its original shape after the external force is removed. Elastomeric materials have high elastic modulus and strength. Common elastomeric materials include metals, rubber, and springs. In this embodiment, the first structural plate 14 is preferably made of metal, and more preferably stainless steel, which ensures that the first structural plate 14 has a certain structural strength and also a certain elasticity. When the first structural plate 14 is subjected to an external force, such as when the external force has a certain angle with the side of the first side plate 11 with a larger area, the first structural plate 14 will generate a certain amount of deformation. Moreover, as the external force increases, the amount of deformation generated by the first structural plate 14 will also increase. As the external force decreases, the amount of deformation generated by the first structural plate 14 will also decrease until the external force disappears. The first structural plate 14 can then return to its initial state. Furthermore, the direction of deformation of the first structural plate 14 is the same as or approximately the same as the opposite direction of the external force. That is, depending on the direction of the external force, the first structural plate 14 can bend and deform towards the second side plate 12 or towards the direction away from the second side plate 12.

[0038] A second structural plate 15 may also be provided on the second side plate 12. The structure of the second structural plate 15 is preferably the same as or similar to that of the first structural plate 14, and the material of the second structural plate 15 is preferably the same as that of the first structural plate 14, i.e., the second structural plate 15 is preferably made of metal, and more preferably stainless steel. This ensures that the second structural plate 15 has a certain structural strength and also a certain degree of elasticity. When the second structural plate 15 is subjected to an external force, for example, if the external force is at a certain angle to the side of the second side plate 12 with a larger area, the second structural plate 15 will produce a certain amount of deformation. As the external force increases, the amount of deformation of the second structural plate 15 will also increase; as the external force decreases, the amount of deformation of the second structural plate 15 will also decrease until the external force disappears, at which point the second structural plate 15 can return to its initial state. Furthermore, the direction of deformation of the second structural plate 15 is the same as or approximately the same as the opposite direction of the external force. That is, depending on the direction of the external force, the second structural plate 15 can bend and deform towards the first side plate 11 or towards the opposite direction of the first side plate 11.

[0039] Reference Figure 6In this embodiment, a first structural plate 14 is provided on the first side plate 11, and a second structural plate 15 is provided on the second side plate 12. In this way, the first structural plate 14 and the second structural plate 15 can deform simultaneously, and the amount of deformation is the same or approximately the same. This not only ensures that the bracket 2 is located in the middle position of the first side plate 11 and the second side plate 12, which can improve the overall stability of the equipment, but also prevents the first structural plate 14 and the second structural plate 15 from deforming too much, which would prevent the first structural plate 14 and the second structural plate 15 from failing to return to their initial state. This can extend the service life of the first structural plate 14 and the second structural plate 15, and at the same time ensure the adjustment accuracy of the first structural plate 14 and the second structural plate 15.

[0040] The frame 1 may also include a crossbeam 13, with the two ends of the crossbeam 13 connected to the first side plate 11 and the second side plate 12, respectively. The two ends of the crossbeam 13 may be connected to the top of the first side plate 11 and the top of the second side plate 12, so that the frame 1 is roughly inverted U-shaped.

[0041] The two ends of the crossbeam 13 can also be connected to the bottom of the first side plate 11 and the bottom of the second side plate 12, respectively, making the frame 1 roughly U-shaped. The two ends of the crossbeam 13 can also be connected between the top and bottom of the first side plate 11 and the top and bottom of the second side plate 12, respectively, making the frame 1 roughly H-shaped. In this embodiment, the two ends of the crossbeam 13 are connected to approximately the middle positions of the first side plate 11 and the second side plate 12, respectively, and the distances from the two ends of the crossbeam 13 to the bottom of the frame 1 are equal. The first side plate 11 and the second side plate 12 can be connected to the two ends of the crossbeam 13 by welding, snap-fitting, screw fastening, etc. In this embodiment, the first side plate 11 and the second side plate 12 are connected to the two ends of the crossbeam 13 by screw fastening. The H-shape of the frame 1 improves the overall stability and structural strength of the frame 1, preventing shaking or deformation during use. The frame 1 can be integrally formed or modular. In this embodiment, the frame 1 is a split type, and the two ends of the crossbeam 13 can be connected to the first side plate 11 and the second side plate 12 by means of welding, snap-fitting, screw fastening, etc. In some embodiments, the frame 1 may only include the first side plate 11 and the second side plate 12, without including the crossbeam 13.

[0042] The crossbeam 13 may include a first crossbeam 131 and a second crossbeam 132. Both the first crossbeam 131 and the second crossbeam 132 are flat plate structures. The two ends of the first crossbeam 131 are respectively connected to the first side plate 11 and the second side plate 12, and the two ends of the second crossbeam 132 are respectively connected to the first side plate 11 and the second side plate 12. The first crossbeam 131 and the second crossbeam 132 are symmetrically arranged, preferably symmetrical about the center connection line of the first side plate 11 and the second side plate 12, which can make the structure of the frame 1 more stable.

[0043] A clearance hole 133 extending along the length direction is provided in the middle of the crossbeam 13. The bracket 2 can be raised and lowered through the clearance hole 133. The clearance hole 133 can be rectangular, elliptical, or other shapes. The width of the clearance hole 133 is greater than the width of the bracket 2, and the length of the clearance hole 133 is greater than the length of the bracket 2 to ensure that the bracket 2 can pass through the clearance hole 133 during raising and lowering. The first crossbeam 131 and the second crossbeam 132 are arranged at intervals, such that the gap between the first crossbeam 131 and the second crossbeam 132 forms the clearance hole 133. In some embodiments, the crossbeam 13 can be a single flat plate structure with the clearance hole 133 provided on it.

[0044] Reference Figure 1 , Figure 4 The bracket 2 is vertically and flexibly mounted on the frame 1. More specifically, the bracket 2 is vertically and flexibly positioned between the first side plate 11 and the second side plate 12. The bracket 2 is used to mount the coating component 6, which is preferably positioned at the center of the bracket 2. The bracket 2 can move the coating component 6 up or down, allowing it to reach a predetermined position. The bracket 2 is preferably made of a rigid material, such as stainless steel, and has a large thickness to ensure sufficient structural strength and prevent deformation during use. The coating component 6 is used to coat the perovskite solution onto the conductive substrate. The coating component 6 can be a coating head for slot coating and is positioned on the side of the bracket 2 facing the conductive substrate. In this embodiment, the coating component 6 is positioned on the side of the bracket 2 facing the bottom of the frame 1.

[0045] Reference Figure 4 The support 2 is generally H-shaped, which provides high structural strength and prevents deformation during use. The support 2 is equipped with wiring holes 21 and reinforcing ribs 22. There can be multiple wiring holes 21, preferably evenly distributed across the support 2. These holes allow air supply pipes or wires to pass through, making the wiring more standardized and neat, while also reducing the weight of the support 2 and lessening the load on the drive assembly 4. There can also be multiple reinforcing ribs 22, preferably evenly distributed across the support 2. These ribs further enhance the structural strength of the support 2, reduce deformation, and improve coating accuracy. The reinforcing ribs 22 can extend along the height direction, the length direction, or a combination of both.

[0046] Reference Figure 1 , Figure 3 , Figure 6The drive assembly 4 is disposed on the frame 1. More specifically, at least part of the drive assembly 4 may be disposed on the first side plate 11 or on the first structural plate 14. In this embodiment, the drive assembly 4 is disposed on the first structural plate 14 and is connected to one end of the bracket 2. The other end of the bracket 2 may not be connected to the drive assembly 4. The drive assembly 4 has driving force and is used to drive the bracket 2 to rise and fall.

[0047] At least part of the drive assembly 4 can also be disposed on the second side plate 12 or the second structural plate 15. In this embodiment, the drive assembly 4 is disposed on the second structural plate 15, and the drive assembly 4 is connected to one end of the bracket 2. The other end of the bracket 2 may not be connected to the drive assembly 4. The drive assembly 4 has driving force and is used to drive the bracket 2 to rise and fall.

[0048] At least some of the drive components 4 may also be simultaneously disposed on the first side plate 11 and the second side plate 12, or at least some of the drive components 4 may also be simultaneously disposed on the first structural plate 14 and the second structural plate 15. In this embodiment, at least some of the drive components 4 are simultaneously disposed on the first structural plate 14 and the second structural plate 15, and the drive components 4 are respectively connected to both ends of the bracket 2. The drive components 4 have driving force and are used to drive the bracket 2 to rise and fall.

[0049] The drive component 4 can be a servo module, or other types of drive components. For example, the drive component 4 includes a motor and a guide rail. The drive end of the motor moves up and down or extends and retracts along the guide rail, and the bracket 2 is connected to the drive end of the motor. The drive component 4 can drive the bracket 2 to move up and down along the height direction of the frame 1, thereby enabling the coating part 6 to move up and down along the height direction of the frame 1, so that the coating part 6 reaches a predetermined position. By adjusting the position of the coating part 6, the distance between the coating part 6 and the conductive substrate can be controlled, thereby controlling the thickness of the perovskite solution coating on the conductive substrate.

[0050] Reference Figure 8 In the figure, the solid line indicates that when the height difference between the two ends of the bracket 2 is zero, the first structural plate 14 and the second structural plate 15 are in the initial state and are not subjected to any force in the direction of the bracket 2. The dashed line indicates that when the height of the two ends of the bracket 2 increases, the first structural plate 14 and the second structural plate 15 are subjected to a force in the direction of the bracket 2, and the first structural plate 14 and the second structural plate 15 tilt toward the bracket 2 to keep the installation spacing of the bracket 2 constant.

[0051] When the position of one end of the bracket 2 relative to the other end of the bracket 2 changes along the height direction of the frame 1, the first structural plate 14 and / or the second structural plate 15 deform to keep the length of the line connecting the two points respectively connected to the two ends of the bracket 2 constant. In this embodiment, both the first structural plate 14 and the second structural plate 15 are provided, and the first structural plate 14 and the second structural plate 15 have the same structure and material. The length of the line connecting the two points connected to the two ends of the bracket 2 is the installation spacing of the bracket 2. When the difference between the height of one end of the bracket 2 to the bottom of the frame 1 and the height of the other end of the bracket 2 to the bottom of the frame 1 changes, the installation spacing of the bracket 2 also changes accordingly. In this embodiment, the example is taken when the height difference between the two ends of the bracket 2 is zero, and neither the first structural plate 14 nor the second structural plate 15 is subjected to a force in the direction of the bracket 2.

[0052] When the height difference between the two ends of the bracket 2 increases, the installation spacing of the bracket 2 increases. At this time, both the first structural plate 14 and the second structural plate 15 are subjected to a force in the direction of the bracket 2, and the force increases as the installation spacing of the bracket 2 increases. The deformation of the first structural plate 14 and the second structural plate 15 also increases as the force increases, and the degree of inclination of the first structural plate 14 and the second structural plate 15 toward the bracket 2 also increases, ultimately making the installation spacing of the bracket 2 remain unchanged.

[0053] When the height difference between the two ends of the bracket 2 decreases, the installation spacing of the bracket 2 decreases. At this time, both the first structural plate 14 and the second structural plate 15 are subjected to a force in the direction of the bracket 2, and the force decreases as the installation spacing of the bracket 2 decreases. The deformation of the first structural plate 14 and the second structural plate 15 also decreases as the force decreases, and the degree of inclination of the first structural plate 14 and the second structural plate 15 toward the bracket 2 also decreases, so that the installation spacing of the bracket 2 remains unchanged.

[0054] This invention utilizes the elastic properties of the first structural plate 14 and the second structural plate 15. By deforming the first structural plate 14 and the second structural plate 15, the installation spacing at both ends of the bracket 2 can remain unchanged. This not only simplifies the adjustment steps and facilitates operation, but also improves adjustment efficiency and accuracy, especially since the coating part 6 requires frequent adjustment. Furthermore, it eliminates the need to move the side plates of the frame 1. At the same time, the first structural plate 14 and the second structural plate 15 have high structural strength, ensuring the stability of the overall structure of the equipment, thereby ensuring the stability of equipment operation and improving the coating quality. In addition, it reduces the number of parts used in the equipment, simplifies the equipment structure, and lowers the equipment cost.

[0055] Reference Figure 1 , Figure 3The balancing component 5 is connected to the support 2 and applies a force to the support 2 in the direction opposite to gravity. That is, the balancing component 5 can directly apply a force to the support 2 in the direction opposite to gravity; this force can be a tensile force or a supporting force in the direction opposite to gravity. The balancing component 5 can be a cylinder module, or other types of balancing components. As an example, the balancing component 5 includes a cylinder and a push rod. The cylinder drives the push rod to rise or fall or extend and retract. The cylinder can also keep the push rod stationary and maintain a certain tensile or pushing force. The support 2 is connected to the push rod, meaning the balancing component 5 can apply a certain tensile or pushing force to the support 2. The balancing component 5 can at least partially share the load of the drive component 4, thus reducing the load on the drive component 4. This is especially important before and after the coating component 6 is installed on the bracket 2. Without the balancing component 5, the load on the drive component 4 would change significantly, potentially leading to a decrease in its positioning accuracy. However, with the balancing component 5, the force exerted by the balancing component 5 on the bracket 2 after the coating component 6 is installed reduces the load on the drive component 4, or keeps the load on the drive component 4 within a preset range. This improves the repeatability of the drive component 4 or ensures it maintains a high repeatability, improving product quality, extending its service life, reducing replacement frequency, increasing equipment efficiency, and lowering operating and maintenance costs. The load primarily refers to the weight of the bracket 2 or the weight of the coating component 6, or it can refer to both.

[0056] As a preferred method, refer to Figure 6The first structural plate 14 may include a first free end 141 and a first fixed end 142. The first fixed end 142 is connected to the first side plate 11. The first fixed end 142 can be connected to the first side plate 11 by welding, snap-fitting, screw locking, or other methods. The first structural plate 14 and the first side plate 11 can also be integrally formed. The first structural plate 14 and the first side plate 11 can be made of the same material or different materials. In this embodiment, the first structural plate 14 and the first side plate 11 are integrally formed and are made of the same material. The first structural plate 14 can be disposed at the top, middle, bottom, and side of the first side plate 11. In this embodiment, the first side plate 11 is provided with a first through hole 111. The first fixed end 142 of the first structural plate 14 is connected to the inner wall of the first through hole 111, so that the first through hole 111 is U-shaped or inverted U-shaped. When the first fixed end 142 of the first structural plate 14 is connected to the end of the first through hole 111 near the bottom of the frame 1, the first through hole 111 can be made into an inverted U-shape. When the first fixed end 142 of the first structural plate 14 is connected to the end of the first through hole 111 near the top of the frame 1, the first through hole 111 can be made into a U-shape. The first through hole 111 is preferably located in the middle or approximately in the middle of the first side plate 11, so that the first structural plate 14 is also located in the middle or approximately in the middle of the first side plate 11.

[0057] Reference Figure 6 The second structural plate 15 may also include a second free end 151 and a second fixed end 152. The second fixed end 152 is connected to the second side plate 12. The second fixed end 152 can be connected to the second side plate 12 by welding, snap-fitting, screw locking, or other methods. The second structural plate 15 and the second side plate 12 can also be integrally formed. The second structural plate 15 and the second side plate 12 can be made of the same material or different materials. In this embodiment, the second structural plate 15 and the second side plate 12 are integrally formed and are made of the same material. The second structural plate 15 can be disposed at the top, middle, bottom, and side of the second side plate 12. In this embodiment, the second side plate 12 is provided with a second through hole 121. The second fixed end 152 of the second structural plate 15 is connected to the inner wall of the second through hole 121, so that the second through hole 121 is U-shaped or inverted U-shaped. When the second fixed end 152 of the second structural plate 15 is connected to the end of the second through hole 121 near the bottom of the frame 1, the second through hole 121 can be made into an inverted U-shape. When the second fixed end 152 of the second structural plate 15 is connected to the end of the second through hole 121 near the top of the frame 1, the second through hole 121 can be made into a U-shape. The second through hole 121 is preferably located in the middle or approximately in the middle of the second side plate 12, so that the second structural plate 15 is also located in the middle or approximately in the middle of the second side plate 12.

[0058] The extension direction of the first free end 141 of the first structural plate 14 and the extension direction of the second free end 151 of the second structural plate 15 are preferably the same. This ensures that when the first structural plate 14 and the second structural plate 15 are subjected to external force, the deformation amounts of the first structural plate 14 and the second structural plate 15 can be the same or approximately the same. In this embodiment, the first fixed end 142 of the first structural plate 14 is preferably connected to the end of the first through hole 111 near the bottom of the frame 1, and the second fixed end 152 of the second structural plate 15 is preferably connected to the end of the second through hole 121 near the bottom of the frame 1.

[0059] Reference Figure 1 , Figure 3 , Figure 4 The coating auxiliary balancing device 100 may also include a support component 3, which mainly serves as a connection and support. The drive component 4 is connected to the bracket 2 through the support component 3, and the drive component 4 drives the bracket 2 to rise and fall through the support component 3. Compared with the drive component 4 directly driving the bracket 2, the driving force of the drive component 4 is transmitted to the bracket 2 through the support component 3, which makes the rise and fall of the bracket 2 more gradual and stable, and keeps the bracket 2 in a stable position.

[0060] The support component 3 is also connected to the drive component 4 and can also be connected to the balance component 5. The balance component 5 can apply a force against gravity to the bracket 2 through the support component 3. Compared with the balance component 5 being directly connected to the bracket 2, the force of the balance component 5 is transmitted to the bracket 2 through the support component 3. This makes the force on the bracket 2 more moderate and stable, and keeps the bracket 2 in a stable position.

[0061] Reference Figure 3 , Figure 5 , Figure 7 Each support component 3 may include a first support member 31 and a second support member 32, which are interconnected. The first support member 31 is mounted on the bracket 2, and the two first support members 31 can be connected to both ends of the bracket 2 by welding, snap-fitting, screw fastening, or other methods. In this embodiment, the two first support members 31 are connected to both ends of the bracket 2 by screw fastening, and the first support member 31 is connected to the side of the bracket 2 where the coating component 6 is mounted.

[0062] The second support member 32 connects the drive assembly 4 and the balancing assembly 5. The two second support members 32 can be connected to the two drive assemblies 4 respectively by welding, snap-fitting, or screw fastening. In this embodiment, the two second support members 32 are connected to the two drive assemblies 4 respectively by screw fastening. The second support members 32 can transmit the driving force of the drive assembly 4 and the force of the balancing assembly 5 to the bracket 2 through the first support member 31. When the coating component 6 is installed onto the bracket 2, the drive assembly 4 and the balancing assembly 5 are usually in a stopped state. If the bracket 2 is rigidly connected to the drive assembly 4 and the balancing assembly 5 at this time, it is easy to cause impact to the drive assembly 4 and the balancing assembly 5, which may lead to damage or a decrease in accuracy of the drive assembly 4 and the balancing assembly 5. To solve this problem, in this invention, the first support member 31 and the second support member 32 are pivotally connected. This can buffer the driving force of the drive assembly 4 and the force of the balancing assembly 5, making the movement of the bracket 2 more stable and improving the positioning accuracy of the drive assembly 4. Especially during the installation of the coating component 6, the above structure can play a good buffering role without affecting the accuracy of the drive assembly 4 and the balancing assembly 5 when they are working.

[0063] Reference Figure 7 The second support member 32 may include a U-shaped support plate 321 and a horizontal plate 322. The horizontal plate 322 is located inside the U-shaped support plate 321 and is connected to the inner walls of both sides of the U-shaped support plate 321. The horizontal plate 322 can enhance the overall structural strength of the second support member 32. The bottom of the U-shaped support plate 321 is connected to the drive assembly 4. The bottom of the U-shaped support plate 321 can be connected to the drive assembly 4 by welding, snap-fitting, screw fastening, etc. In this embodiment, the bottom of the U-shaped support plate 321 is connected to the drive assembly 4 by screw fastening. The horizontal plate 322 is connected to the balance assembly 5. The horizontal plate 322 can be connected to the balance assembly 5 by welding, snap-fitting, screw fastening, etc. In this embodiment, the horizontal plate 322 is connected to the balance assembly 5 by screw fastening. The second support member 32 passes through the first through hole 111 on the first side plate 11 or the second through hole 121 on the second side plate 12. The U-shaped support plate 321 can be integrally formed or split. In this embodiment, the U-shaped support plate 321 includes a first support plate 3211 and a second support plate 3212. Both the first support plate 3211 and the second support plate 3212 are L-shaped, and the first support plate 3211 and the second support plate 3212 are combined to form the U-shaped support plate 321.

[0064] The number of drive components 4, support components 3, and balancing components 5 can be one or more. When there is only one drive component 4, it can drive one end of the bracket 2 to rise and fall while the other end of the bracket 2 does not rise or fall; or, it can drive both ends of the bracket 2 to rise and fall simultaneously. When there is only one balancing component 5, it can be connected to one end of the bracket 2, or it can be connected to a position near the middle of the bracket 2.

[0065] As a preferred method, refer to Figure 1 , Figure 3 There are two drive components 4, two support components 3, and two balance components 5. One drive component 4 is respectively installed on the first side plate 11 and the second side plate 12. Each drive component 4 drives one end of the bracket 2 to move up and down via a support component 3. Each balance component 5 applies a force against gravity to one end of the bracket 2 or one support component 3; that is, each balance component 5 exerts an upward pulling or supporting force on one end of the bracket 2 or one support component 3, and the force of the balance component 5 is opposite to the direction of gravity of the bracket 2. The two drive components 4, two support components 3, and two balance components 5 are symmetrically arranged at both ends of the frame 1. That is, each end of the frame 1 has one drive component 4, one support component 3, and one balance component 5. This allows the coating auxiliary balancing device 100 to maintain greater balance and stability, and makes the force exerted by the balance components 5 on both ends of the bracket 2 more uniform, thus making the load on each drive component 4 more uniform.

[0066] Two drive components 4 are connected to both ends of the bracket 2 via support components 3. This ensures that the bracket 2 remains balanced and that the two drive components 4 are subjected to uniform force, resulting in more stable and smooth operation. It also prevents excessive load from affecting positioning accuracy or causing damage to the drive components 4. In this embodiment, the two drive components 4 are respectively disposed on the side of the first side plate 11 and the second side plate 12 facing away from the bracket 2. In some embodiments, the two drive components 4 may also be disposed on the side of the first side plate 11 and the second side plate 12 facing the bracket 2, or one drive component 4 may be disposed facing the bracket 2 and the other drive component 4 facing away from the bracket 2.

[0067] The two drive components 4 can simultaneously drive both ends of the bracket 2 to move in the same direction, or simultaneously drive both ends of the bracket 2 to move in opposite directions, or one drive component 4 can drive one end of the bracket 2 to move while the other drive component 4 remains stationary. In other words, the two drive components 4 are independent of each other; they can drive the bracket 2 together simultaneously or drive it independently. When the bracket 2 needs to rise or fall as a whole, both drive components 4 can drive the bracket 2 to rise or fall simultaneously, maintaining the relative horizontality of both ends of the bracket 2. When one end of the bracket 2 needs to rise and the other end needs to fall, one drive component 4 can drive one end of the bracket 2 to rise, and the other drive component 4 can drive the other end of the bracket 2 to fall. When only one end of the bracket 2 needs to rise or fall, only one drive component 4 needs to drive that end of the bracket 2 that needs to rise or fall. In this embodiment, the two driving components 4 are set independently of each other, and the position of the bracket 2 can be adjusted according to actual needs. This can eliminate problems such as uneven heights at both ends of the bracket 2 or the coating component 6 caused by part processing errors or assembly errors, ensuring that the two ends of the bracket 2 remain balanced. This, in turn, ensures that the coating component 6 remains parallel to the conductive substrate, that is, ensures that the two ends of the coating component 6 facing the conductive substrate are at the same distance from the conductive substrate. This not only adjusts the thickness of the perovskite solution coating on the conductive substrate, but also makes the perovskite solution uniformly coated on the conductive substrate, thereby improving the photoelectric conversion efficiency of the solar cell.

[0068] Two balancing components 5 are respectively disposed at both ends of the frame 1 and are symmetrically arranged, that is, the two balancing components 5 are symmetrically arranged about the center line of the support 2. The two balancing components 5 are respectively disposed on the side of the first side plate 11 and the second side plate 12 facing the support 2. In this embodiment, the two balancing components 5 are respectively disposed on the side of the first side plate 11 and the second side plate 12 facing the support 2. In some embodiments, the two balancing components 5 may also be respectively disposed on the side of the first side plate 11 and the second side plate 12 facing away from the support 2, or one balancing component 5 may be disposed facing the support 2 and the other balancing component 5 may be disposed facing away from the support 2.

[0069] Two balancing components 5 can simultaneously apply forces to both ends of the bracket 2, distributing the load borne by each drive component 4 and ensuring that the loads on the two drive components 4 are the same or approximately the same. Preferably, the force of each balancing component 5 is adjustable, setting it to be the same or approximately the same, so that both ends of the bracket 2 are simultaneously subjected to the same or approximately the same force. This means that each balancing component 5 can also distribute the load of the drive component 4 in the same or approximately the same way, thus reducing the load borne by each drive component 4 and ensuring that the load on each drive component 4 is the same or approximately the same. This maintains consistent adjustment accuracy between the two drive components 4, preventing a decrease in adjustment accuracy due to different loads on the drive components 4. Furthermore, depending on whether the coating component 6 is installed on the bracket 2, the force applied to the bracket 2 or support component 3 in the direction away from gravity can be increased or decreased to keep the load on the drive component 4 constant, reducing the impact of load changes on the positioning accuracy of the drive component 4, thereby further improving the repeatability of the drive component 4 and extending its service life.

[0070] In one specific implementation, refer to Figure 1 , Figure 2 , Figure 3 The coating auxiliary balancing device 100 may further include a control component 7 and a sensor 8. The sensor 8 is used to sense whether the coating part 6 is mounted on the bracket 2, and the control component 7 is used to control the operation of the drive component 4 and the balancing component 5. As long as the sensor 8 can determine whether the coating part 6 is mounted on the bracket 2, the installation position of the sensor 8 can be set as needed. For example, the sensor 8 can be mounted on the bracket 2, or at other positions within the coating auxiliary balancing device 100, or it can be installed independently. The sensor 8 can be a proximity sensor, a gravity proximity sensor, a vision proximity sensor, etc. The sensor 8 and the control component 7 can be connected via a wire or wirelessly. In this embodiment, the sensor 8 is mounted on the bracket 2, and the sensor 8 is a proximity sensor. The sensor 8 and the control component 7 are connected via a wire. When the coating part 6 is mounted on the bracket 2, the sensor 8 can transmit a signal to the control component 7.

[0071] Reference Figure 2The control component 7 may include a controller 71 and a switching element 72. The controller 71 is electrically connected to the switching element 72 and controls the magnitude of the force applied by the balancing component 5 through the switching element 72. There are two controllers 71 and two switching elements 72, respectively located at both ends of the frame 1. Each switching element 72 may include a first switching element 721 and a second switching element 722. The first switching element 721 and the second switching element 722 can allow the balancing component 5 to apply different magnitudes of force; for example, the first switching element 721 can apply a large force to the balancing component 5, and the second switching element 722 can apply a small force to the balancing component 5.

[0072] When the coating component 6 is installed on the bracket 2, the sensor 8 senses that the coating component 6 is installed on the bracket 2 and transmits the signal to the controller 71. The controller 71 switches the first switching element 721 to connect with the balancing component 5. The force of the balancing component 5 increases, that is, the force exerted by the balancing component 5 on the bracket 2 increases, so that the load on the drive component 4 remains basically unchanged.

[0073] When the coating component 6 is removed from the support 2, the sensor 8 detects that the coating component 6 has been removed from the support 2 and transmits the signal to the controller 71. The controller 71 switches the second switching element 722 to connect with the balancing component 5. The force of the balancing component 5 decreases, that is, the force exerted by the balancing component 5 on the support 2 decreases, so that the load on the drive component 4 remains basically unchanged.

[0074] The total change in force between the two balancing components 5 is equal to or approximately equal to the weight of the coating part 6. Sensor 8 detects whether the coating part 6 is mounted on the support 2. Controller 71 selects the switching element 72 connected to the balancing component 5 to change the force exerted by the balancing component 5 on the support 2 or the supporting component 3 in the direction away from gravity. This ensures that the load on the drive component 4 remains constant, reducing the impact of load changes on the positioning accuracy of the drive component 4, thereby further improving the repeatability and extending the service life of the drive component 4. Sensor 8 and controller 71 automatically switch the force of the balancing component 5, eliminating the need for manual adjustment by operators. This simplifies the operation process and prevents changes in the load on the drive component 4 or different loads on the two drive components 4 due to operator forgetfulness or improper operation, which could lead to a decrease in the positioning accuracy of the drive component 4. Compared to manual operation, the control component 7 and sensor 8 offer higher control precision and sensitivity.

[0075] This invention provides a control method for the coating auxiliary balancing device 100 as described above. When the coating component 6 is mounted on the support 2, the control balancing component 5 increases the force applied to the support 2 or the support component 3 in the direction away from gravity. When the coating component 6 is removed from the support 2, the control balancing component 5 decreases the force applied to the support 2 or the support component 3 in the direction away from gravity.

[0076] Specifically, after the coating component 6 is installed on the bracket 2, the sensor 8 detects that the coating component 6 is installed on the bracket 2 and transmits the signal to the controller 71. The controller 71 increases the force against gravity applied to the bracket 2 or support component 3 by the switching element 72, so that the load on the drive component 4 remains unchanged. In other words, the load on the drive component 4 remains unchanged before and after the coating component 6 is installed on the bracket 2, reducing the impact of load changes on the positioning accuracy of the drive component 4, thereby further improving the repeatability of the drive component 4 and extending its service life. The drive component 4 can also drive the support component 3. The two drive components 4 can drive the support component 3 simultaneously or separately. The support component 3 drives the bracket 2, thereby adjusting the position of the coating component 6 so that the side of the coating component 6 facing the conductive substrate is parallel to the conductive substrate, that is, the distance from both ends of the coating component 6 to the conductive substrate is equal. This not only adjusts the thickness of the perovskite solution coating on the conductive substrate, but also makes the perovskite solution uniformly coated on the conductive substrate, improving the photoelectric conversion efficiency of the solar cell.

[0077] When the coating component 6 is removed from the bracket 2, the sensor 8 detects this and transmits the signal to the controller 71. The controller 71 reduces the force exerted by the balancing component 5 on the bracket 2 or the support component 3 in the direction away from gravity by switching element 72, ensuring that the load on the drive component 4 remains constant. In other words, the load on the drive component 4 remains constant before and after the coating component 6 is installed on the bracket 2, reducing the impact of load changes on the positioning accuracy of the drive component 4, thereby further improving the repeatability and extending its service life. The drive component 4 can also drive the support component 3. Both drive components 4 can drive the support component 3 simultaneously or separately. The support component 3 drives the bracket 2, thereby adjusting the position of the bracket 2 so that the side of the bracket 2 facing the conductive substrate is parallel to the conductive substrate, meaning the distances from both ends of the bracket 2 to the conductive substrate are equal. Thus, after the coating component 6 is installed on the bracket 2, it ensures that the side of the coating component 6 facing the conductive substrate is parallel to the conductive substrate, meaning the distances from both ends of the coating component 6 to the conductive substrate are equal.
