Description

Technical Field

[0001] This application belongs to the field of spraying equipment technology, specifically a spraying device, a method of use, and its application. Background Technology

[0002] Currently, polymer materials are widely used as structural materials for the outer surfaces of spacecraft due to their excellent mechanical properties, lightweight characteristics, and good photothermal stability. Especially in the low Earth orbit space environment, spacecraft are exposed to complex conditions such as strong oxidizing atomic oxygen, ultraviolet radiation, and drastic temperature changes. Surface materials are prone to oxidative degradation, mass loss, and even perforation failure, severely impacting the spacecraft's on-orbit lifespan and reliability. Atomic oxygen erodes polymer molecular chains, causing chemical bond breakage, surface abrasion, and scouring; ultraviolet radiation damages the internal structure of materials through photochemical decomposition, reducing their mechanical strength; and thermal cycling stress, due to the periodic alternation of sunlight and shadow in orbit, causes repeated expansion and contraction of materials, accelerating the formation of fatigue cracks. These degradation processes severely affect the on-orbit lifespan and reliability of spacecraft, potentially leading to functional component failure or mission interruption. Therefore, it is common practice to prepare atomic oxygen protective layers on the surfaces of critical spacecraft components to improve their environmental adaptability.

[0003] In the preparation of atomic oxygen protective layers, spraying technology is widely used due to its flexibility and applicability. However, the numerous irregularly shaped structural components in spacecraft, such as tubular, curved, and asymmetrical cross-section components, pose significant challenges to uniform, stable, and efficient spraying operations. Existing spraying equipment is mostly designed for regular planar or rotationally symmetric structures, making it difficult to adapt to irregularly shaped components with large surface curvature variations, local depressions or protrusions, and complex edge transitions. This often leads to problems such as uneven coating thickness, localized missed spraying, or overspraying. Furthermore, the atomic oxygen protective layer prepared using this method effectively avoids atomic oxygen erosion on the surface of structural components.

[0004] Furthermore, existing spraying systems also have significant shortcomings in the positioning and clamping of irregularly shaped parts. Traditional fixtures are mostly rigid fixed structures, making it difficult to achieve precise support and positioning of irregularly shaped parts. Moreover, during the spraying process, the reaction force of the airflow can easily cause the workpiece to shift or rotate, thus affecting the consistency and adhesion of the coating. At the same time, the adjustment of the spray gun mostly relies on manual operation, lacking precise control over parameters such as spraying path, distance, and angle, making it difficult to meet the requirements for high-precision, repeatable aerospace-grade coating preparation.

[0005] To address at least one of the aforementioned problems, it is necessary to provide a spraying system adapted to irregularly shaped structural parts in order to improve the preparation quality and efficiency of coatings (especially antigenic oxygen coatings) for irregularly shaped parts. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, a spraying device, a method of use, and its application are provided. The main purpose is to improve the preparation quality and efficiency of coatings for irregularly shaped parts, especially atomic oxygen coatings, and to significantly improve the ability of atomic oxygen to erode and scour by adopting surface treatment technology, so as to ensure long-term stability and reliability in atomic oxygen-rich environments such as low Earth orbit.

[0007] The technical solution adopted in this application to solve its technical problems and to achieve the objectives of overcoming the aforementioned technical problems is as follows: A spraying device, method of use, and application described in this application include: a device body; a positioning component installed on the device body, the positioning component including a limiting post, a positioning seat, and a support seat, one end of the limiting post having the positioning seat, the device body having a positioning groove at the positioning seat position, and the device body having the support seat on the limiting post away from the positioning seat, the positioning seat and the positioning groove being detachably connected, the limiting post overlapping the support seat, adapted to have a suspended positioning area between the limiting post and the support seat, the positioning area being used to set irregularly shaped parts; and a spraying mechanism including a moving mechanism, a mounting frame, and a spray gun, the moving mechanism being installed on the device body, the moving mechanism having the mounting frame, and the mounting frame having the spray gun, adapted to controllably move the spray gun on the mounting frame along the extension direction of the limiting post axis and spray the irregularly shaped parts. The spraying equipment is used for spraying atomic oxygen modified layers onto irregularly shaped structural parts. Through the coordination of the aforementioned positioning components and spraying mechanism, precise positioning and efficient spraying of irregularly shaped structural parts can be achieved. In actual operation, the irregularly shaped part is first placed in the positioning area, and the limiting posts, positioning seats, and support seats ensure stable positioning of the part, preventing displacement during spraying. The moving mechanism drives the spray gun to move along the axis of the limiting posts. The spray gun can precisely adjust the spraying angle and range according to the specific shape and size of the irregularly shaped part, ensuring that the atomic oxygen modified layer is evenly covered on the surface of the structural part. The atomic oxygen protective layer prepared by this equipment is significantly different from traditional coatings. Its preparation process, through optimized material ratios and processing parameters, significantly improves the coating's density and makes its internal structure more uniform and compact. This high density effectively reduces the microscopic channels for atomic oxygen penetration, thus more comprehensively resisting the erosive effects of atomic oxygen, especially avoiding the scouring problem common in traditional coatings, namely the gradual damage of the coating's bottom and edges by atomic oxygen. In addition, this protective layer can maintain stable chemical inertness and mechanical strength even when exposed to atomic oxygen for a long time, which improves the overall protective performance and is suitable for the surface protection needs of equipment such as spacecraft and satellites.

[0008] In some embodiments, the limiting post is inserted into the irregular central hole of the irregular part, and the surface of the limiting post abuts against at least a portion of the structure of the inner wall of the irregular central hole. The limiting post is a tubular structural member. The limiting post is provided with an anti-rotation member, and the anti-rotation member abuts against the irregular central hole in a rotational direction centered on the axis of the limiting post.

[0009] In some embodiments, the irregularly shaped component includes an upper part and a lower part, the upper and lower parts having the same shape and symmetrically fastening to form the central irregularly shaped hole, and forming fixing edges on both sides of the central irregularly shaped hole. Both the upper and lower parts have a first concave portion, a convex portion, and a second concave portion at a position between the fixing edges on both sides. The first and second concave portions are symmetrically connected to the sides of the convex portion in a tangential transition state. The first and second concave portions are tangentially connected between the corresponding fixing edges on both sides. The first and second concave portions have a preset first radius. The first arc structure has a circular point located outside the irregularly shaped central hole. The outward protrusion is a second arc structure with a preset second radius, and the circular point of the second arc structure is located in the middle of the irregularly shaped central hole. The irregularly shaped central hole has a central area and two narrow areas. The central area is located between two symmetrically arranged outward protrusions, and the two narrow areas are located between two first concave portions and two second concave portions, respectively. The anti-rotation component is adapted to the shape of the narrow areas, and is suitable for abutting against the inner wall of the first concave portion and / or the inner wall of the second concave portion. This anti-rotation structure can effectively limit the rotation of the irregularly shaped part around the axis of the limiting post, ensuring that the irregularly shaped part always maintains a preset posture during the spraying process, avoiding deviation of the spraying path or uneven coating thickness due to workpiece rotation, thereby improving spraying accuracy and coating consistency. At the same time, the shape adaptation design of the anti-rotation component and the narrow areas can further enhance the connection stability between the irregularly shaped part and the limiting post, reduce the impact of spraying airflow on the workpiece positioning state, and provide a reliable structural guarantee for subsequent precise spraying.

[0010] In some embodiments, the moving mechanism includes a first guide component and a power component. The first guide component includes a first guide rail and a first slider.

[0016] In some embodiments, the fixed plate is further provided with a control element, which is adapted to control the movement of the movable end of the control element to drive the handle switch of the spray gun to control the switching of the spray gun between the off mode and the spraying mode.

[0018] An application of a spraying device, wherein the above-mentioned spraying device is used for spraying an antigen oxygen-modified layer on the surface of an irregularly shaped part.

[0019] Compared with the prior art, the spraying equipment, method of use and application provided in this application have the following beneficial effects: 1. This application provides a spraying device, a method of use, and its application. The device comprises a main body, a positioning component, and a spraying mechanism. The positioning component is used to restrict and position irregularly shaped parts, and the spraying mechanism is mainly used to perform spraying operations on the positioned irregularly shaped parts. The positioning component includes a limiting post, a positioning seat, and a support seat. The positioning seat is located at one end of the limiting post. The support seat and a positioning groove are connected to the main body of the device. The positioning groove and the positioning seat correspond to and are compatible with each other. The support seat is located at the end of the limiting post away from the positioning seat. This achieves high-quality and efficient spraying of a proton-modified oxygen layer onto the entire outer surface of the irregularly shaped part.

[0020] 2. This application provides a spraying device, a method of use, and its application. The device uses an irregularly shaped part comprising an upper and a lower part, both of which are composites of multiple standard shapes. Each part includes a fixed edge, a first concave portion, a convex portion, and a second concave portion. An anti-rotation component is placed in a narrow area and adapted to the shape of the narrow area, such that the anti-rotation component abuts against the inner wall of the first concave portion, or against the inner wall of the second concave portion, or multiple anti-rotation components abut against the inner walls of the first and second concave portions respectively. This ensures that the positioning component accurately adapts to the irregularly shaped part, guaranteeing reliable, stable, and effective positioning of the part, and ensuring that the part exhibits no deformation or minimal deformation below a preset value. This protects the irregularly shaped part and improves the spraying quality.

[0021] 3. This application provides a spraying device, a method of use, and its application. The spraying mechanism includes a moving mechanism, a mounting frame, and a spray gun. The mounting frame includes a fixed frame, an adjusting mechanism, and a fixed plate. The adjusting mechanism includes a horizontal member, a screw, and an adjusting plate. Rotating the adjusting plate drives the screw to move up and down. The fixed plate is located at the bottom of the screw. Therefore, when the adjusting plate is rotated and the screw is moved up and down, the screw will drive the horizontal member and the fixed plate to move up and down, and the fixed plate can then drive the spray gun to move up and down. This allows the position of the spray gun nozzle facing the surface of the irregularly shaped part to be sprayed to be adjustable, so as to achieve a uniform and comprehensive spraying effect on the surface of the irregularly shaped part.

[0022] 4. This application provides a spraying device, a method of use, and its application. By having the spray gun nozzles at different preset installation positions at the same distance from the core position of the area to be sprayed, each area to be sprayed receives a relatively consistent thick coating. Furthermore, the nozzle direction of the spray gun is adapted to the different shape characteristics of the area to be sprayed, thereby achieving better spraying quality.

[0023] 5. This application provides a spraying device, a method of use, and its application. A control component is also provided on the fixed plate. The movable end of the control component can move and drive the handle of the spray gun to rotate open and close, thereby realizing the opening and closing control of the spray gun spraying. Generally, the control component can adopt a telescopic movement mode. Furthermore, a cylinder power actuator can be used to realize the reliable control of the movable end of the control component, ensuring that the spray gun switches between the closed mode and the spraying mode.

Detailed Implementation

[0026] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the application; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" can mean not only "only one" but also "more than one."

[0028] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] Currently, polymer materials are widely used as structural materials for the outer surfaces of spacecraft due to their excellent mechanical properties, lightweight characteristics, and good photothermal stability. Especially in the low Earth orbit environment, where spacecraft are exposed to complex space conditions such as strong oxidizing atomic oxygen, ultraviolet radiation, and drastic temperature changes, surface materials are prone to oxidative degradation, mass loss, and even perforation failure, severely impacting the spacecraft's on-orbit lifespan and reliability. Therefore, it is common practice to prepare atomic oxygen protective layers on the surfaces of critical spacecraft components to improve their environmental adaptability.

[0032] In the preparation of protective layers, spraying technology is widely used due to its flexibility and applicability. However, the numerous irregularly shaped structural components in spacecraft, such as tubular, curved, and asymmetrical cross-section components, pose significant challenges to uniform, stable, and efficient spraying operations. Existing spraying equipment is mostly designed for regular planar or rotationally symmetric structures, making it difficult to adapt to the characteristics of irregularly shaped components, such as large surface curvature variations, local depressions or protrusions, and complex edge transitions. This leads to frequent problems such as uneven coating thickness, localized missed spraying, or overspraying.

[0033] Furthermore, existing spraying systems have shortcomings in the positioning and clamping of irregularly shaped parts 400. Traditional fixtures are mostly rigid fixed structures, making it difficult to achieve precise support and positioning of irregularly shaped parts 400. During the spraying process, the workpiece is prone to displacement or rotation due to airflow reaction force, affecting coating consistency and adhesion. At the same time, the adjustment of the spray gun 330 relies heavily on manual operation, lacking precise control over parameters such as spraying path, distance, and angle, making it difficult to meet the requirements for high-precision, repeatable aerospace-grade coating preparation.

[0034] To address at least one of the aforementioned problems, it is necessary to provide a spraying system adapted to irregularly shaped structural parts in order to improve the preparation quality and efficiency of 400 antigenic oxygen coatings for irregularly shaped parts.

[0035] The following are some representative embodiments, intended to facilitate a clear and complete understanding and implementation of this application. However, they do not imply that the scope of protection of this application is limited to the scope of the representative embodiments, nor do they limit other optional implementation methods within the scope of protection of this application.

[0036] like Figure 1-5As shown, in some embodiments, a spraying device includes a device body 100, a positioning component 200, and a spraying mechanism 300. The device body 100 is generally a frame-type basic working platform base. The positioning component 200 and the spraying mechanism 300 are provided on the device body 100. The positioning component 200 is used to restrict and position the irregular part 400, and the spraying mechanism 300 is mainly used to perform spraying operations on the irregular part 400 in the positioning state.

[0037] Specifically, in some embodiments, the positioning component 200 includes a limiting post 210, a positioning seat 220, and a support seat 230. The positioning seat 220 is provided at one end of the limiting post 210. The limiting post 210 and the positioning seat 220 can be connected in a detachable and quick-installation manner, or the limiting post 210 and the positioning seat 220 can be completely fixed together. This mainly ensures that the limiting post 210 and the positioning seat 220 maintain a stable connection relationship during operation, without any specific restrictions. The support seat 230 and the positioning groove 240 are connected to the device body 100. The positioning groove 240 and the positioning seat 220 correspond to and are adapted to each other. The support seat 230 is located at the end of the limiting post 210 away from the positioning seat 220.

[0038] Therefore, when spraying the irregular part 400, it is generally necessary to first insert the end of the limiting post 210 away from the positioning seat 220 into the irregular part 400, and then place the limiting post 210 containing the irregular part 400 on the equipment body 100, so that the end of the limiting post 210 away from the positioning seat 220 is placed on the support seat 230, and the bottom of the positioning seat 220 is inserted into the positioning groove 240. At this time, the irregular part 400 is located in the positioning area 250 between the positioning seat 220 and the support seat 230, and the irregular part 400 is in a suspended state to facilitate... The surface of the irregular part 400 is sprayed. In the spraying process, the upper half of the irregular part 400 is preferably sprayed. After the upper half of the irregular part 400 is sprayed, the limiting post 210 and the positioning seat 220 with the irregular part 400 are removed. Then the limiting post 210 is rotated 180 degrees along its own axis and then repositioned and reinstalled. The spraying operation is then carried out to achieve the spraying operation of the entire outer surface of the irregular part 400. After the spraying of one irregular part 400 is completed, a new irregular part 400 is reinstalled.

[0039] The spraying mechanism 300 includes a moving mechanism 310, a mounting frame 320, and a spray gun 330. The moving mechanism 310 can control and drive the mounting frame 320 to move, and the mounting frame 320 will drive the spray gun 330 to move. By moving the spray gun 330, it can move from one end of the irregular part 400 and spray it synchronously to the other end of the irregular part 400, so as to realize continuous spraying operation on the top surface of the irregular part 400.

[0040] In some embodiments, the irregularly shaped part 400 has an irregularly shaped central hole 410 at its center. A limiting post 210 is adapted to the irregularly shaped central hole 410. The limiting post 210 can be inserted through one end opening of the irregularly shaped central hole 410, ultimately positioning the irregularly shaped part 400 in the positioning area 250 of the limiting post 210. A positioning seat 220 is located on one side of the irregularly shaped part 400. The end of the limiting post 210 away from the positioning seat 220 extends into the irregularly shaped part 400, facilitating the extension of the irregularly shaped part 400 to overlap with the support seat 230. The support seat 230 does not affect the suspended state of the irregularly shaped part 400. When the limiting post 210 is inserted into the irregularly shaped central hole 410 of the irregularly shaped part 400, the surface of the limiting post 210 abuts against the inner wall of the irregularly shaped central hole 410. Due to the symmetrical structure of the irregularly shaped part 400, the limiting post 210 is not completely... The shape of the limiting post 210 is identical to that of the irregular part 400, so that at least part of the surface structure of the limiting post 210 abuts against the corresponding structure of the inner wall of the irregular central hole 410. This satisfies the positioning and limiting requirements of the irregular part 400. Since the irregular part 400 is elongated, the full insertion of the limiting post 210 can effectively limit and support the irregular part 400 as a whole, avoiding bending problems of the irregular part 400 as a whole or in parts due to the influence of the support position, the combined effect of the irregular part 400's gravity, or the influence of temperature difference during spraying. The surface of the limiting post 210 is preferably a circular tubular structure, which can reduce the design and manufacturing cost of the limiting post 210. Furthermore, the limiting post 210 does not have a large contact area with the interior of the irregular central hole 410, which can reduce the friction during loading and unloading, thereby improving loading and unloading efficiency.

[0041] Since the rotational freedom of the tubular limiting post 210 and the irregular part 400 is only restricted through, for example, an interference fit, when the spray gun 330 is spraying, the impact force of the sprayed material may cause the irregular part 400 to rotate on the limiting post 210 to overcome the frictional force of the interference fit. This can prevent the irregular part 400 from effectively receiving the preset spraying effect, leading to spraying quality problems, such as missing spray coating on parts of the irregular part 400 or uneven spray coating thickness on the surface of the irregular part 400. Therefore, by limiting the... An anti-rotation component 260 is provided on the positioning post 210. The anti-rotation component 260 is adapted to the irregular central hole 410. We know that the positioning post 210 and the irregular central hole 410 are not in a state of full area contact. Therefore, there will be a gap between the irregular central hole 410 and the positioning post 210. The anti-rotation component 260 is set in the gap position and abuts against the inner wall of the corresponding position of the irregular central hole 410, so that the anti-rotation component 260 can completely restrict the irregular part 400 in the rotation direction, ensuring the positioning effect of the irregular part 400.

[0042] In some embodiments, the irregularly shaped part 400 of this application specifically includes an upper part 420 and a lower part 430. The upper part 420 and the lower part 430 have the same shape and are symmetrically arranged and fastened together. A through irregularly shaped central hole 410 is formed between the upper part 420 and the lower part 430. The edge positions of the upper part 420 and the lower part 430 are attached to form a fixed edge 440. Therefore, the fixed edge 440 is located on both sides of the irregularly shaped central hole 410. The fixed edge 440 is generally formed by welding, but is not limited to this method.

[0043] Both the upper part 420 and the lower part 430 are combinations of multiple standard shapes. Each part includes a fixing edge 440 on one side, a first concave portion 450, an outward convex portion 460, and a second concave portion 470, and a fixing edge 440 on the other side. Since the two fixing edges 440 on both sides have the same shape, and the first and second concave portions 450 and 470 have the same shape, they are symmetrically distributed on both sides of the outward convex portion 460 with the center line of the outward convex portion 460 as the center of symmetry. The outward convex portion 460 is also... With its symmetrical shape along its centerline, both the upper part 420 and the lower part 430 are symmetrical. The upper part 420 and the lower part 430 interlock symmetrically, resulting in a symmetrical cross-section for the irregularly shaped part 400 in both the transverse and longitudinal directions. For ease of production, reduced stress concentration, and improved aesthetics, the fixing edge 440 on one side, the first concave portion 450, the convex portion 460 and the second concave portion 470, and the fixing edge 440 on the other side are typically distributed sequentially with smooth, tangential transitions between adjacent parts. The first concave portion 450 and the second concave portion 470 are both first arc structures with a predetermined first radius, and the convex portion 460 is a second arc structure with a predetermined second radius. Preferably, the first and second radii are the same, but this is not a limitation. The center point of the first arc structure is located outside the irregular central hole 410, and the center point of the second arc structure is located in the center of the irregular central hole 410, so that the irregular central hole 410 includes a central area 411 and two narrow areas 412 on both sides of the central area 411. The central area 411 is located between two symmetrically arranged outward protrusions 460, and the two narrow areas 412 are located between two symmetrically arranged first inward concave parts 450 and between two second inward concave parts 470, respectively.

[0044] In some embodiments, by disposing the anti-rotation member 260 in the narrow area 412 and adapting it to the shape of the narrow area 412, the anti-rotation member 260 abuts against the inner wall of the first recess 450, or the anti-rotation member 260 abuts against the inner wall of the second recess 470, or multiple anti-rotation members 260 abut against the inner walls of the first recess 450 and the second recess 470 respectively, so that the positioning component 200 of this application can be accurately adapted to the irregular part 400 of this application, ensuring reliable, stable and effective positioning of the irregular part 400, and ensuring that the irregular part 400 has no deformation or a slight deformation below a preset value, thereby protecting the irregular part 400 and improving the coating quality.

[0045] In some embodiments, the moving mechanism 310 includes a first guide component 311 and a power component 312. The first guide component 311 adopts a first guide rail 3111 and a first slider 3112. The power component 312 includes a transmission belt 3121 and a power source 3122. Both the first transmission belt 3121 and the first slider 3112 are connected to the mounting frame 320. Power is output through the power source 3122, which drives the transmission belt 3121 to move. The transmission belt 3121 drives the mounting frame 320 to move, allowing the mounting frame 320 to move with the first slider 3111. 12 moves stably along the guiding direction of the first guide rail 3111. Generally, two first guide components 311 can be provided. The two first guide rail 3111 components and the power component 312 are arranged in parallel, and the power component 312 is positioned between the two first guide rail 3111 components. This ensures that the two first sliders 3112 and the transmission belt 3121 are connected to the mounting frame 320. Driven by the transmission belt 3121, the mounting frame 320 will move along the preset direction under the guidance of the two first sliders 3112, ensuring the stable operation of the mounting frame 320.

[0046] In some embodiments, the mounting bracket 320 includes a fixed bracket 321, an adjustment mechanism 322, and a fixed plate 323. The fixed plate 323 is connected to the fixed bracket 321 through the adjustment mechanism 322, and the fixed plate 323 can be adjusted up and down on the fixed bracket 321 through the adjustment mechanism 322. A spray gun 330 is provided on the fixed plate 323. By adjusting the fixed plate 323, the distance between the spray gun 330 and the irregular part 400 will be controlled to ensure that the distance between the spray gun 330 and the irregular part 400 is in the optimal position.

[0047] Specifically, the transmission belt 3121 and the first slider 3112 are connected by a fixing frame 321. The fixing frame 321 has a stand 3211, and the stand 3211 is provided with a second guide assembly 3212. The second guide assembly 3212 includes a second guide rail 3212-1 and a second slider 3212-2. The second guide rail 3212-1 is connected to the stand 3211. The second slider 3212-2 can be adjusted up and down on the second guide rail 3212-1, and the second slider 3212-2 is on the side of the second guide rail 3212-1 close to the irregular part 400. The adjustment mechanism 322 includes a horizontal member 3221, a screw 3222, and an adjustment plate 3223. The horizontal member 3221 is connected to the second slider 3212-2 and extends from the second slider 3212-2 to the top of the limiting post 210. The top of the horizontal member 3221 is connected to the screw 3222, and the adjustment plate 3223 is rotatably connected to the top of the vertical member 3211. The adjustment plate 3223 is threadedly connected to the screw 3222. Rotating the adjustment plate 3223 will drive the screw 3222 to adjust up and down. A fixing plate 323 is provided at the bottom of the screw 3222. Therefore, when the adjustment plate 3223 is rotated and the screw 3222 is driven to adjust up and down, the screw 3222 will drive the horizontal member 3221 and the fixing plate 323 to move up and down. The fixing plate 323 can then drive the spray gun 330 to adjust up and down.

[0048] In other embodiments, the mounting bracket 320 includes a fixed bracket 321, an adjustment mechanism 322, and a fixed plate 323. The fixed plate 323 can be adjusted in height on the fixed bracket 321 by the adjustment mechanism 322. A spray gun 330 is mounted on the fixed plate 323, which allows for adjustment of the vertical position of the spray gun 330. By setting a preset mounting position on the fixed plate 323, the spray gun 330 can be detachably connected to the preset mounting position. Therefore, the orientation of the nozzle of the spray gun 330 can be finely adjusted. Specifically, the distance between the nozzle of the spray gun 330 and the area 480 to be sprayed on the irregular part 400 can be adjusted, or the orientation of the nozzle of the spray gun 330 can be adjusted, but not limited to these, so as to achieve a uniform and comprehensive spraying effect on the surface of the irregular part 400.

[0049] In some embodiments, the preset mounting positions include a first mounting position 3231, a second mounting position 3232, a third mounting position 3233, a fourth mounting position 3234, and a fifth mounting position 3235. The area to be sprayed 480 is divided into a first sub-spray area 481, a second sub-spray area 482, a third sub-spray area 483, a fourth sub-spray area 484, and a fifth sub-spray area 485 according to the structural characteristics of the upper part 420 or the lower part 430 of the irregular part 400. The first sub-spray area 481 is the outer surface of the first concave portion 450, the second sub-spray area 482 is the outer surface of the fixing edge 440 at one side, the third sub-spray area 483 is the outer surface of the convex portion 460, and the fifth sub-spray area 3235 is the outer surface of the convex portion 460. Spray area 484 is the outer surface of the fixed edge 440 on the other side, and the fifth sub-spray area 485 is the outer surface of the second recess 470; the first mounting position 3231, the second mounting position 3232, the third mounting position 3233, the fourth mounting position 3234 and the fifth mounting position 3235 correspond to the first sub-spray area 481, the second sub-spray area 482, the third sub-spray area 483, the fourth sub-spray area 484 and the fifth sub-spray area 485 respectively.

[0050] By installing the spray gun 330 on at least one of the first mounting position 3231, the second mounting position 3232, the third mounting position 3233, the fourth mounting position 3234, and the fifth mounting position 3235, a comprehensive and uniform spraying effect can be achieved on the first sub-spray area 481, the second sub-spray area 482, the third sub-spray area 483, the fourth sub-spray area 484, and the fifth sub-spray area 485. When high efficiency is desired, multiple spray guns 330 can be simultaneously installed at each preset mounting position to achieve simultaneous spraying of multiple areas 480 to be sprayed. When cost savings are required, by installing the spray gun 330 at one preset mounting position and completing one corresponding area 480 to be sprayed, the spraying program can be repeatedly executed by switching preset mounting positions to achieve spraying operations on different areas 480 to be sprayed. Specifically, after completing one spraying operation, the spray gun 330 is switched to another preset mounting position, and then the moving mechanism 310 is restarted to repeatedly execute the operation to complete the spraying operation.

[0051] In some embodiments, the spray gun 330 can be installed in a preset mounting position, including but not limited to the first mounting position 3231, the second mounting position 3232, the third mounting position 3233, the fourth mounting position 3234, and the fifth mounting position 3235, by means of quick-connect clips. The spray gun 330 is positioned between the quick-connect clips and the fixing plate 323, and the quick-connect clips and the fixing plate 323 can be quickly and detachably connected by means of fasteners, for example. Therefore, the quick-connect clips and the fixing plate 323 will have connecting holes, which can be through holes or threaded holes, etc. At least some of the connecting holes can be oblong holes, so that the relative position between the quick-connect clips and the fixing plate 323 can be adjusted when connected, thereby allowing fine adjustment of the position and nozzle direction of the spray gun 330, and is not limited to this.

[0052] In some embodiments, the nozzles of the spray guns 330 at different preset installation positions are equidistant from the core position of the area to be sprayed 480. The core position of the area to be sprayed 480 is understood as follows: for the first sub-spray area 481 and the fifth sub-spray area 485, it is the farthest area of ​​the first sub-spray area 481 and the fifth sub-spray area 485 relative to the corresponding nozzle of the spray gun 330; for the second sub-spray area 482, the third sub-spray area 483 and the fourth sub-spray area 484, it is the closest area of ​​the second sub-spray area 482, the third sub-spray area 483 and the fourth sub-spray area 484 relative to the corresponding nozzle of the spray gun 330.

[0053] In other embodiments, the nozzle of the spray gun 330 corresponding to the first sub-spray area 481 is located on the line connecting the center point of the first concave portion 450 and the center point of the convex portion 460, and the spray gun 330 can spray towards the surface of the first concave portion 450 along the direction of the connecting line. The nozzle of the spray gun 330 corresponding to the second sub-spray area 482 is located at the top of the fixed edge 440 on one side, and the spray gun 330 can spray vertically downward toward the surface of the fixed edge 440 on that side. The nozzle of the spray gun 330 corresponding to the third sub-spray area 483 is located at the top of the protrusion 460, and the spray gun 330 can spray vertically downward toward the surface of the protrusion 460. The nozzle of the spray gun 330 corresponding to the fourth sub-spray area 484 is located at the top of the fixed edge 440 on the other side, and the spray gun 330 can spray vertically downward toward the surface of the fixed edge 440 on that side. The nozzle of the spray gun 330 corresponding to the fifth sub-spray area 485 is located on the line connecting the center point of the second concave portion 470 and the center point of the convex portion 460, and the spray gun 330 can spray along the direction of the line toward the surface of the second concave portion 470.

[0054] Therefore, the core position of the first sub-spray area 481 is located at the intersection of the nozzle of the corresponding spray gun 330 along the line connecting the center point of the first concave portion 450 and the center point of the convex portion 460, and the surface of the first sub-spray area 481. The core position of the second sub-spray area 482 is located at the vertical position of the nozzle of the corresponding spray gun 330 towards one side of the fixed edge 440. The core position of the third sub-spray area 483 is located at the highest point of the convex portion 460. The core position of the fourth sub-spray area 484 is located at the vertical position of the nozzle of the corresponding spray gun 330 towards the other side of the fixed edge 440. The core position of the fifth sub-spray area 485 is located at the intersection of the nozzle of the corresponding spray gun 330 along the line connecting the center point of the second concave portion 470 and the center point of the convex portion 460, and the surface of the fifth sub-spray area 485. The above settings will ensure that each area 480 to be sprayed receives a relatively consistent thick coating, and the nozzle direction of the spray gun 330 will be adapted to the different shape characteristics of the areas 480 to be sprayed, thus achieving better spraying quality.

[0055] In some embodiments, the fixed plate 323 is further provided with a control component 331. The movable end of the control component 331 can move and drive the handle of the spray gun 330 to rotate open and close, thereby realizing the opening and closing control of the spray gun 330. Generally, the control component 331 can adopt a telescopic movement mode, and then through a cylinder power actuator, the movable end of the control component 331 can be reliably controlled to ensure that the spray gun 330 switches between the closed mode and the spraying mode.

[0056] In other embodiments, a magnetically positioned spray gun 330 can be used. The spraying route can be designed based on the shape of the irregularly shaped part 400, and spraying at specific locations can be determined based on predictions of those locations, or reciprocating spraying can be performed according to a PLC program. The spray gun 330 is mounted on a permanent magnet adsorption structure and is equipped with a rotary switch; left and right rotation enables adsorption and release. The installation, removal, and spraying process of the irregularly shaped part 400 are simple and convenient, while also eliminating the thermal deformation effects of heat treatment on the part 400. This system can design the spray gun 330 as a PLC-controlled program, combined with a high-degree-of-freedom positioning design, to formulate spraying routes for different irregularly shaped parts 400. Simultaneously, the PLC system controls the spraying distance and speed during the spraying process, thereby stabilizing parameters and solving parameter stability issues.

Those skilled in the art should understand that this application is not limited to the above embodiments.
