[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0035] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structures in the molding mold and molding method of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the meaning of "multiple" is more than two, and the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected; the directions or positional relationships indicated by the terms "upper", "lower", "left", "right", "inside", "outside", etc. 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, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] In the existing wind turbine blade preparation process, the blade can be first formed through the steps of laying, pouring, grinding, etc., and then it is usually necessary to select materials to form a coating on the blade surface according to the use environment of the blade or the functions to be added, such as paint. In this painting process, the material can be applied to the blade surface using a brush roller and other components. When using a brush roller, it is usually necessary to directly connect the feed pipe to the brush roller, and there is a certain amount of hydraulic pressure in the pipe to transfer the material to be coated to the brush roller through the feed pipe and soak the brush roller.

[0038] On this basis, the applicant found that in existing painting tools, in order to make the brush roller flexible, the feed pipe is usually made of a hose and its length is usually longer. Due to the pressure inside that squeezes the material forward, after closing the feed valve, a certain amount of material still remains in the tube, and this part of the material will rush out under pressure and flow to the brush roller, resulting in uneven film thickness during the painting process.

[0039] In order to solve the above problems, the embodiments of the present application provide a painting assembly and a painting device, which can conveniently and accurately control the outflow of materials, thereby improving the uniformity of painting.

[0040] It is understandable that the following embodiments of the present application only illustrate the application of the painted component to wind turbine blades, but the application of the painted component provided in the embodiments of the present application is not limited to the following embodiments, and the coating material is not limited to paint. It can also be used in other occasions where it is necessary to evenly apply the material to the surface of a component and protect it.

[0041] In order to better understand this application, Figures 1 to 4 Describe in detail.

[0043] In the first aspect, according to an embodiment of the present application, a painting assembly 100 is proposed, comprising: a support frame 10; a spray module 20, which is arranged on the support frame 10, the spray module 20 comprises a feeding portion 21, a diverter portion 22 and a spray portion 23, the feeding portion 21 is provided with a feeding valve, the diverter portion 22 has a feed port 221 and a plurality of discharge ports 222 which are interconnected, the spray portion 23 comprises a plurality of nozzles 231, the feed port 221 is connected to the feeding valve, the plurality of discharge ports 222 are respectively connected to the plurality of nozzles 231, and the plurality of nozzles 231 are arranged at intervals along a first direction X; a painting module 30, which is arranged on the support frame 10, the painting module 30 comprises a paint roller 31, the paint roller 31 is arranged on the side of the nozzle 231 away from the diverter portion 22 and is arranged opposite to the nozzle 231.

[0044] The embodiment of the present application first provides a painting assembly 100, which can be optionally used to apply a functional coating on the surface of a blade of a wind turbine generator set, and includes a support frame 10, a spray module 20, and a painting module 30. Specifically, the support frame 10 is used to support and fix the spray module 20 and the painting module 30, the spray module 20 is used to spray the material to be coated (hereinafter referred to as paint) to the painting module 30, and the painting module 30 is used to roll the material evenly to the surface to be painted.

[0045] The support frame 10 may be composed of a plurality of rod-shaped members and / or a plurality of plate-shaped members, and may be detachably connected to the spray module 20 and the painting module 30. When the painting assembly 100 is used, the painting assembly 100 may be stably moved by connecting to the support frame 10 via a robot arm.

[0046] The spray module 20 is used to transfer paint and spray the paint to the painting module 30. The spray module 20 can be connected to the component storing the paint to facilitate the feeding. The spray module 20 includes a feeding part 21, a diverter 22 and a spray part 23. The feeding part 21 can be provided with a channel for the paint to flow through, a pump to promote the flow of the paint and other related components, and a feeding valve is also provided. The feeding valve can control the on-off of the aforementioned channel. When the feeding valve is closed, the paint can be trapped outside the painting component 100 and in the feeding part 21, effectively preventing the paint from continuing to flow.

[0047] The diverter section 22 is used to divert the paint flowing into the feeding section 21. The diverter section 22 may be provided with a feed port 221 connected to the feeding section 21 and a plurality of discharge ports 222 connected to the spraying section 23. The diverter section 22 is used to evenly divert a large amount of paint entering through the feed port 221 to each discharge port 222 so that the paint flows into the spraying section 23 through the discharge port 222.

[0048] The spraying part 23 includes a plurality of spray heads 231, which can be connected to the discharge ports 222 one by one, and are used to spray the paint flowing out of the discharge ports 222 to the painting module 30, so as to perform the painting work. Optionally, each spray head 231 in the spraying part 23 can have the same structural shape.

[0049] The painting module 30 is used to contact the surface to be painted and apply the paint to form a film. The painting module 30 includes a paint roller 31, which can evenly apply the material on the blade surface by rolling after infiltration. The paint roller 31 is arranged opposite to the nozzle of the nozzle 231, so that the material sprayed by the nozzle 231 can be accurately received by the paint roller 31.

[0050] In the painting assembly 100 provided in the embodiment of the present application, the supply of paint can be timely and accurately cut off by the supply valve in the supply part 21, and the accommodating space inside the diverter 22 is small, the amount of paint residue is small, and the material inside the diverter 22 usually needs to be extruded under pressure. After the supply valve is closed, the paint in the diverter 22 will not be further sprayed out. At the same time, by setting a plurality of nozzles 231 to spray the paint onto the paint roller 31, the paint on the paint roller 31 can be evenly distributed. In summary, the painting assembly 100 can effectively improve the thickness uniformity of the film layer formed by the paint.

[0051] In some optional embodiments, the feeding part 21, the diversion part 22, the spray part 23 and the paint roller 31 are arranged in sequence along the second direction Y, and the first direction X intersects with the second direction Y; in the second direction Y, the orthographic projection of the paint roller 31 covers the orthographic projections of multiple nozzles 231.

[0052] In order to make the paint flow smoothly, the feeding part 21, the diverter part 22, the spray part 23 and the paint roller 31 can be arranged correspondingly in the second direction Y, that is, the orthographic projections of the above four in the second direction Y are at least partially overlapped with each other, and the overlapping area accounts for a large proportion of the overall orthographic projection area. The first direction X and the second direction Y are arranged to intersect, and can further be arranged to be perpendicular to each other.

[0053] On this basis, the paint roller 31 can be made to have a certain size, and its orthographic projection in the second direction Y can cover the orthographic projection of each nozzle 231, so that the two are arranged opposite to each other, and the nozzle 231 can accurately spray the paint to the paint roller 31. During operation, the second direction Y can be selected to be parallel to the vertical direction or have a small angle to further facilitate the downward flow of the paint, and can be evenly sprayed to the paint roller 31 under the combined effect of the spraying pressure and gravity.

[0054] In some optional embodiments, the spraying portion 23 includes 8 to 20 spray heads 231 , and the plurality of spray heads 231 are arranged at equal intervals along the first direction X. In the first direction X, the interval between adjacent spray heads 231 is 5 mm to 10 mm.

[0055] A plurality of nozzles 231 spaced apart along the first direction X may be provided in the spray section 23, and the specific number thereof may be selected to be between 8 and 20. The number of nozzles 231 and the spacing between adjacent nozzles 231 may be selected according to the length of the paint roller 31 in the first direction X, and the spacing may be selected to be within the range of 5 mm to 10 mm.

[0056] For example, in an embodiment where the length dimension of the paint roller 31 is 360 mm, the spray section 23 may be provided with 14 nozzles 231, the spacing between adjacent nozzles 231 may be 7 mm to 8 mm, and the spacing between the outermost nozzle 231 and the edge of the diversion section 22 may be 8 mm to 10 mm.

[0057] By providing a plurality of nozzles 231 and performing flow diversion corresponding to the number of nozzles 231 , the uniformity of spraying paint can be further improved, the paint roller 31 can be evenly infiltrated, and the uniformity of the film layer formed by roller coating can be further improved.

[0058] See also Figure 3 , Figure 3 1 is a schematic diagram of the structure of a diversion section provided by an embodiment of the present application. In some optional embodiments, a primary diversion slot 223 and a secondary diversion slot 224 are provided in the diversion section 22, one end of the primary diversion slot 223 is connected to the feed port 221, and the other end is connected to a plurality of diversion ports 225, one end of the secondary diversion slot 224 is connected to a plurality of diversion ports 225, and the other end is connected to a plurality of discharge ports 222, and the number of diversion ports 225 is less than the number of discharge ports 222.

[0059] The spray module 20 in the painting assembly 100 includes a diverter 22, which is used to evenly divert the paint flowing out of the feeding part 21 to each nozzle 231, so that the rate of spraying paint from each nozzle 231 is the same or close, thereby making the paint roller 31 evenly infiltrated. In order to further improve the diversion effect and provide uniformity of spraying, a plurality of diverter slots can be provided in the diverter 22 at the same time, for example, a primary diverter slot 223 and a secondary diverter slot 224 can be optionally provided. In the diverter 22, the diverter slots can be connected in sequence in the order of the feed port 221-the primary diverter slot 223-the diverter port 225-the secondary diverter slot 224-the discharge port 222.

[0060] Specifically, the first-level diverter groove 223 is used to evenly divert the paint entering from the feed port 221 to multiple diverter ports 225, and the second-level diverter groove 224 is used to further disperse the paint entering from the multiple diverter ports 225 to multiple outlet ports 222. Thus, the number of outlet ports 222 is greater than the number of diverter ports 225 and greater than the number of feed ports 221. The outlet ports 222 can be optionally connected to the nozzles 231 in a one-to-one correspondence, thereby evenly dispersing and transmitting the paint to each nozzle 231.

[0061] For example, the painting assembly 100 may be provided with one feed port 221 , six diversion ports 225 , and fourteen discharge ports 222 , and the two-stage diversion arrangement can effectively provide paint with an equal flow rate to a large number of nozzles 231 .

[0062] In some optional embodiments, the secondary diversion groove 224 includes a first sub-groove 2241, a second sub-groove 2242 and a plurality of connecting sub-grooves 2243, the first sub-groove 2241 and the second sub-groove 2242 both extend in the first direction X, the connecting sub-groove 2243 is connected between the first sub-groove 2241 and the second sub-groove 2242, the first sub-groove 2241 is connected to the diversion port 225, and the second sub-groove 2242 is connected to the discharge port 222.

[0063] Optionally, the secondary diversion groove 224 is used to further disperse the paint flowing out of the diversion port 225 to multiple outlet ports 222. The secondary diversion groove 224 may include a first sub-groove 2241 and a second sub-groove 2242 that are parallel to each other and extend along the first direction X, wherein the first sub-groove 2241 is used to communicate with multiple diversion ports 225, and the second sub-groove 2242 is used to communicate with multiple outlet ports 222.

[0064] Exemplarily, the first sub-groove 2241 and the second sub-groove 2242 may have a certain length and be connected to multiple diversion ports 225 / multiple discharge ports 222 at the same time. In an embodiment where six diversion ports 225 and fourteen discharge ports 222 are provided in the painting assembly 100, the secondary diversion groove 224 may include two first sub-grooves 2241, which may have the same or similar length and are spaced apart in the first direction X, and each first sub-groove 2241 may be respectively connected to three diversion ports 225. The second sub-groove 2242 may be selected to have a longer length and be connected to fourteen discharge ports 222 at the same time, and these discharge ports 222 may be arranged at equal intervals along the first direction X.

[0065] A plurality of connecting sub-grooves 2243 are connected between the first sub-groove 2241 and the second sub-groove 2242. The connecting sub-grooves 2243 may be extended along the third direction Z. The first direction X, the second direction Y and the third direction Z may intersect each other in pairs, and may be arranged vertically in pairs. The connecting sub-grooves 2243 may extend parallel to each other and be spaced apart in the first direction X.

[0066] Exemplarily, in the embodiment where the aforementioned secondary diversion groove 224 includes two first sub-grooves 2241 and one second sub-groove 2242, each first sub-groove 2241 can be arranged corresponding to multiple connecting sub-grooves 2243, and these connecting sub-grooves 2243 connected to the same first sub-groove 2241 can be arranged at equal intervals in the first direction X to make the diversion more uniform.

[0067] In some optional embodiments, along the second direction Y, the orthographic projection of the first sub-groove 2241 covers the orthographic projections of the multiple branch ports 225, and the orthographic projection of the second sub-groove 2242 covers the orthographic projections of the multiple discharge ports 222; the first sub-groove 2241 has multiple openings 2244 connected to the connecting sub-groove 2243, and along the second direction Y, the distance between the orthographic projection of each branch port 225 and the orthographic projections of two adjacent openings 2244 is the same.

[0068] As mentioned above, the first sub-groove 2241 in the embodiment of the present application can be directly connected to the diversion port 225, and the same first sub-groove 2241 can be simultaneously connected to multiple diversion ports 225. The second sub-groove 2242 can be simultaneously connected to multiple discharge ports 222, and the first sub-groove 2241 and the second sub-groove 2242 are connected via the connecting sub-groove 2243.

[0069] Further, the position where the first sub-groove 2241 and the connecting sub-groove 2243 are connected is recorded as an opening 2244, and the number of the openings 2244 is the same as the number of the connecting sub-groove 2243, and they are arranged at intervals along the first direction X at the groove wall of the first sub-groove 2241. On this basis, the openings 2244 and the diversion ports 225 are orthographically projected along the second direction Y, and the orthographic projections of each diversion port 225 can be located between the orthographic projections of adjacent openings 2244.

[0070] Specifically, here, being located between the orthographic projections of the openings 2244 means drawing a straight line along the first direction X, and then drawing perpendicular lines to the straight line from the center of the orthographic projection of the diverter port 225 and the center of the orthographic projection of the opening 2244, respectively, to form a plurality of first intersections and a plurality of second intersections, and then the first intersection is located between adjacent second intersections, and the spacing between the second intersections on both sides is equal. Given that the openings 2244 and the diverter ports 225 are both arranged along the first direction X, the spacing between the orthographic projections of each diverter port 225 and the orthographic projections of two adjacent openings 2244 is also correspondingly equal, and in the diverter portion 22, the length of the flow channel from the diverter port 225 to two adjacent openings 2244 is also correspondingly equal.

[0071] By making the distances between the diversion opening 225 and the openings 2244 on both sides the same, the uniformity of the diversion can be further improved, thereby improving the uniformity of the film layer formed by roller coating.

[0072] In some optional embodiments, the diversion portion 22 includes a first diversion layer 226, a second diversion layer 227 and a third diversion layer 228 which are stacked in sequence, the first diversion groove 223 and the second diversion groove 224 are respectively arranged in the first diversion groove and the third diversion groove, and the second diversion layer 227 is provided with a through hole 229 passing through along the second direction Y, and the through hole 229 is connected between the diversion port 225 and the second sub-groove 2242.

[0073] In order to facilitate the formation of the aforementioned secondary diversion structure in the diversion portion 22, the diversion portion 22 may include a multi-layer structure stacked in sequence. For example, it may include a first diversion layer 226, a second diversion layer 227, and a third diversion layer 228 stacked in sequence, the first diversion layer 226 is provided with a primary diversion groove 223, and the third diversion layer 228 is provided with a secondary diversion groove 224, so that the diversion portion 22 is easy to process as a whole.

[0074] Specifically, the primary diverter groove 223 may be a groove structure starting from the side surface of the first diverter layer 226 toward the second diverter layer 227 and recessed along the second direction Y, that is, the opening 2244 of at least a part of the primary diverter groove 223 is located on the side surface of the first diverter layer 226 toward the second diverter layer 227, and the feed port 221 may extend along the second direction Y to extend the primary diverter groove 223 to the side surface of the first diverter layer 226 away from the second diverter layer 227. That is, the primary diverter groove 223 may form a closed channel structure through the mutual engagement of the first diverter layer 226 and the second diverter layer 227.

[0075] Similarly, the opening 2244 of the secondary diversion groove 224 arranged in the third diversion layer 228 can be arranged on the side surface of the third diversion layer 228 facing the second diversion layer 227, and can be recessed along the second direction Y to form a closed channel structure by the mutual interlocking of the second diversion layer 227 and the third diversion layer 228.

[0076] The second diversion layer 227 is provided with a through hole 229 which penetrates along the second direction Y, and is used to form a channel between its two opposite side surfaces, thereby connecting the primary diversion groove 223 with the secondary diversion groove 224. The through hole 229 can be optionally arranged to be connected to the diversion port 225 in a one-to-one correspondence.

[0077] By arranging the two diverter grooves to be formed by the mutual interlocking of different diverter layers, each diverter groove can be easy to process, clean or maintain, and the reliability, practicality and service life of the painting component 100 can be further improved.

[0078] In some optional embodiments, the painting module 30 also includes an angle adjustment portion 32, which is connected between the support frame 10 and the paint roller 31. The angle adjustment portion 32 can enable the paint roller 31 to rotate within a reference plane, which is parallel to the first direction X and intersects with the second direction Y.

[0079] The painting module 30 may also include an angle adjustment portion 32 connected between the support frame 10 and the paint roller 31. The angle adjustment portion 32 is used to support the paint roller 31 and provide the paint roller 31 with a certain degree of swinging freedom so that the paint roller 31 can be in close contact with the curved or irregular surface to be painted during operation, maintain a relatively stable contact pressure, and further improve the uniformity of painting.

[0080] In an embodiment in which an angle adjustment portion 32 is provided, the angle adjustment portion 32 can be selected to change the angle of the paint roller 31 by changing its own size at different positions, thereby enabling the paint roller 31 to swing within a reference plane, which can be selected as a plane and can be selected to intersect with the second direction Y, and can be further selected to be perpendicular to the second direction Y, so as to control the contact angle between the paint roller 31 and the surface to be painted.

[0081] In some optional embodiments, the angle adjustment portion 32 includes a plurality of adjusting sub-portions 321 and a connecting rod 322, the connecting rod 322 is rotatably connected to the paint roller 31, the adjusting sub-portion 321 is connected between the connecting rod 322 and the support frame 10, each adjusting sub-portion 321 extends along a third direction Z and has an adjustable size in the third direction Z, and the plurality of adjusting sub-portions 321 are spaced apart in the first direction X.

[0082] Specifically, the angle adjustment portion 32 may include a plurality of adjustment sub-portions 321 and a connecting rod 322, and the connecting rod 322 is used to connect with the paint roller 31. Optionally, the connecting rod 322 may be bent at both ends in the same direction to form a U-shaped structure, and its two ends are respectively rotatably connected to the two ends of the rotating shaft of the paint roller 31, so that the paint roller 31 is connected to the connecting rod 322 and can freely rotate in its own circumferential direction to achieve the painting function.

[0083] The adjusting sub-portion 321 is connected between the connecting rod 322 and the support frame 10. The support frame 10 may be extended at least partially along the first direction X. The multiple adjusting sub-portions 321 may be extended along the third direction Z and arranged at intervals in the first direction X, that is, the multiple adjusting sub-portions 321 are respectively connected to different positions of the connecting rod 322 in the first direction X. Therefore, when the support frame 10 is stationary, the angles of the connecting rod 322 and the paint roller 31 can be adjusted by extending and retracting the adjusting sub-portion 321 in the third direction Z.

[0084] Illustratively, when the surface to be painted is uneven and a certain area is protruding, the protruding area causes the paint roller 31 and the adjusting sub-portion 321 at the corresponding position to be pressed harder than the adjusting sub-portions 321 at other positions, pushing some of the adjusting sub-portions 321 to shrink and shorten, thereby causing the paint roller 31 to tilt with the surface to be painted, thereby maintaining a stable fit and a relatively stable contact pressure with the surface to be painted, thereby improving the uniformity of painting.

[0085] Optionally, the adjusting sub-portion 321 may be provided with a telescopic rod, a spring, an elastic buffer pad or other structural parts capable of telescoping or elastic deformation, so as to realize the function of adjustable size in the third direction Z.

[0086] In some optional embodiments, the angle adjustment portion 32 further includes a pressure sensor 323 , which is connected between the connecting rod 322 and the support frame 10 and extends along the third direction Z.

[0087] In addition to the aforementioned adaptive action adjusting sub-unit 321, a pressure sensor 323 may also be provided in the angle adjusting unit 32, one end of the pressure sensor 323 is connected to the connecting rod 322, and the other end is connected to the support frame 10, so that the pressure at the position can be detected in real time. The size of the pressure parameter can characterize the size and uniformity of the contact pressure between the paint roller 31 and the blade during the roller coating process to a certain extent.

[0088] On this basis, by monitoring and estimating the parameters measured by the pressure sensor 323, the moving speed and moving direction of the paint assembly 100 during the roller coating process can be adjusted in real time, and then the contact pressure and other parameters between the paint roller 31 and the blade can be adjusted accordingly. The uniformity of the paint coating can be further improved through the combined action of the pressure sensor 323 and the aforementioned adaptive adjustment sub-unit 321.

[0089] In some optional embodiments, the adjusting sub-portion 321 includes an elastic member, and in the third direction Z, the difference between the maximum extension dimension and the minimum extension dimension of the elastic member is 15 mm to 25 mm.

[0090] When setting the adjusting sub-portion 321, it can be selected according to the flatness of the area to be painted. If the curvature of the area to be painted is large or the curvature varies greatly, it can be selected to make the length dimension of the adjusting sub-portion 321 have a large variable range.

[0091] On this basis, the elastic modulus and the extension size of the elastic member in the adjusting sub-portion 321 can be adjusted so that there is a difference between the maximum extension size when the elastic member is stretched and the minimum extension size when the elastic member is compressed, and the difference is the variable range of the length size of the adjusting sub-portion 321. Further, the difference can be selected to be between 15 mm and 25 mm, so that the paint roller 31 and the connecting rod 322 have a suitable rotation range.

[0092] In some optional embodiments, within the reference plane, the angle adjustment portion 32 can enable the paint roller 31 to rotate at a maximum angle less than or equal to 25°.

[0093] As mentioned above, the angle adjustment part 32 can make the paint roller 31 swing, so that when the blade surface is a curved surface or the curvature changes, the paint roller 31 can maintain contact with the blade surface through adaptive swinging, thereby improving the quality of painting. On this basis, by adjusting the compressible amount, connection position, elastic modulus and other parameters of the adjustment sub-part 321, or by providing a limit structure at a position such as the connecting rod 322, the maximum inclination angle at which the paint roller 31 can swing can be adjusted accordingly.

[0094] Further, the maximum swing angle of the paint roller 31 can be set to be less than or equal to 25°, where the maximum swing angle refers to the swing angle in a single direction, that is, when the paint roller 31 is viewed from the second direction Y, the posture in which the connecting rod 322 strictly extends along the first direction X is taken as the initial posture, and the paint roller 31 can be optionally rotated 25° clockwise or counterclockwise. That is, the paint roller 31 rotates from the clockwise limit rotation position to the counterclockwise limit rotation position, and the rotation angle during the rotation can be less than or equal to 50°.

[0095] By limiting the maximum rotation angle of the paint roller 31, it is possible to avoid the paint roller 31 rotating too much and colliding with other components, causing structural damage. At the same time, it is possible to avoid the paint roller 31 rotating too much and being misaligned with the nozzle 231, causing the paint to be sprayed to other areas, thereby improving the reliability of the painting component 100.

[0096] In some optional embodiments, the spray portion 23 further includes a spray valve, and at least part of the spray heads 231 are provided with a spray valve.

[0097] Optionally, in order to further improve the accuracy of controlling the flow of paint, a spray valve may be further provided in the spray section 23. The spray valve may be synchronously controlled with the aforementioned feed valve, or the two valves may be independently controlled.

[0098] The spray valve can be used to control the opening and closing of the spray head 231. When the spray valve is closed, the paint is trapped and cannot be sprayed out from the spray head 231, thereby further improving the accuracy of the paint supply control. The spray valve can be selected to adopt a precision control valve similar to the supply valve, and is communicatively connected to the same controller for easy control. At the same time, the spray valve can be set one-to-one with the spray head 231, thereby further improving the accuracy of the control.

In a second aspect, a painting device 200 is provided according to an embodiment of the present application, comprising the painting assembly 100 in any embodiment of the first aspect.

[0103] In some optional embodiments, the painting device 200 includes multiple painting components 100, at least some of which are arranged along the second direction Y, and in the second direction Y, the orthographic projection of each painting component 100 at least partially overlaps with the orthographic projection of an adjacent painting component 100.

[0104] In the embodiment where the painting device 200 includes a plurality of painting assemblies 100, at least some of the painting assemblies 100 are arranged along the second direction Y. Specifically, the arrangement here means that in the second direction Y, there may be a plurality of or a plurality of groups of painting assemblies 100 arranged at intervals, and the plurality of / a plurality of groups of painting assemblies 100 may be arranged not directly opposite to each other in the second direction Y, but at least partially staggered with each other, so as to avoid the area of ​​repeated painting being too wide, resulting in reduced work efficiency.

[0105] Furthermore, when setting these painting assemblies 100, it is optional to make the orthographic projections of each paint roller 31 along the second direction Y overlap partially, so as to avoid forming obvious roller marks between the painting areas formed by adjacent paint rollers 31, resulting in a decrease in the painting effect. At the same time, the overlapping area can be selected to have a narrower width, so as to increase the effective area formed by one roller coating on the basis of the same length of the paint roller 31.

[0106] Taking a painting device 200 including four painting assemblies 100 as an example, each painting assembly 100 can be divided into two groups, each group includes two painting assemblies 100, and the paint rollers 31 in the two painting assemblies 100 in the same group are aligned with each other in the second direction Y, and the two groups of painting assemblies 100 can be arranged at intervals in the second direction Y. If the center points of the paint rollers 31 are connected by straight lines, they can be selected to form a parallelogram shape, so that they can flexibly adapt to blade surfaces with different curvatures and have a higher painting efficiency.
