[0002] A drone is an aircraft controlled by radio remote control equipment or its own program control device. Small, flexible, and versatile, it can carry high-definition cameras for aerial photography, showcasing magnificent landscapes and cityscapes from unique perspectives; in agriculture, it can precisely spray pesticides, improving work efficiency; and in emergency rescue, it can penetrate dangerous areas, providing crucial information for disaster relief. Due to its ease of operation and wide range of applications, it plays a significant role in many industries such as film and television production, surveying and mapping, and logistics, bringing great convenience to people's lives and work.

[0003] In the manufacturing of drone components, surface coating treatments are required, such as applying stealth coatings, waterproof coatings, and wear-resistant coatings. Most drone fuselages are circular, and their outer shells have complex curved surfaces. Current coating devices are not well-suited to these complex shapes, so coating is mostly done manually, resulting in uneven spraying and low efficiency. Therefore, we propose a coating device for drone components with complex curved surfaces. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a coating device for drone parts suitable for complex curved surfaces. This solves the technical problem that current coating devices are not easy to adapt to the complex curved surface shape of drone shells, so the coating process is mostly done manually by hand.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a coating device for UAV parts suitable for complex curved surfaces, including a processing table and a coating mechanism set on the processing table. A support frame is set at the center of the upper end of the processing table, and a mounting frame is set at the upper end of the processing table. The coating mechanism includes a mounting plate fixedly installed at the lower end of the mounting frame. A hollow rotating shaft is rotatably installed at the lower end of the mounting plate. A guide plate is installed at the end of the hollow rotating shaft. A cavity is set inside the guide plate. An air inlet pipe communicating with the cavity is installed on the guide plate. The air inlet pipe is located inside the hollow rotating shaft, and the upper end of the hollow rotating shaft extends out of the hollow rotating shaft. A U-shaped plate is set on the guide plate. A telescopic rod is installed at the lower end of the U-shaped plate. A spray head is installed at the end of the telescopic rod. Connecting rods are symmetrically arranged on the side ends of the telescopic rod. Universal ball bearings are installed at the ends of the connecting rods.

[0006] Preferably, the support frame has a circular top view, the inner diameter of the support frame gradually decreases from bottom to top, and the support frame is shaped like a birdcage.

[0007] Preferably, a driven gear is provided on the hollow rotating shaft, a first motor is provided at the upper end of the mounting plate, and a driving gear is installed at the end of the output shaft of the first motor. The driving gear and the driven gear are meshed and connected for transmission.

[0008] Preferably, the air intake pipe extends above the mounting plate, an air pump is provided on the mounting bracket, an air supply pipe is provided on the air pump, and the end of the air supply pipe is rotatably connected to the air intake pipe through a sealed bearing.

[0009] Preferably, the guide plate is arranged in a downward curved arc along its long axis, and positioning grooves are provided at both the front and rear ends of the guide plate.

The drive gear meshes with the meshing teeth, and air outlets are equidistantly opened at the lower end of the guide plate. The air outlets are located between the meshing teeth.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of a guide plate and telescopic rod structure, features a guide plate that is curved downwards along its long axis to adapt to the shape of the drone's fuselage. This allows the spray head to be adjusted along the guide plate's trajectory to reach different positions for coating. By cooperating with the telescopic rod and universal ball bearings, the distance between the spray head and the fuselage can be automatically adjusted to adapt to the complex curved surface of the fuselage. The rotation of the guide plate ensures uniform spraying. Furthermore, the guide plate, in conjunction with an air pump, can also provide airflow, enabling rapid drying of the coating after spraying. Compared to manual hand-held coating, this effectively avoids the problem of uneven spraying and improves coating quality and efficiency.

[0013] 2. This utility model also designs a support frame structure. The support frame is circular when viewed from above, and the inner diameter gradually decreases from bottom to top, forming an overall birdcage shape. This special structure can stably support the drone's fuselage shell from the inside, ensuring that the position of the parts is fixed during the coating process, thus providing a basic condition for precise coating.

Detailed Implementation

[0021] like Figures 1 to 6As shown, this utility model relates to a coating device for UAV parts with complex curved surfaces, including a processing table 100 and a coating mechanism 200 mounted on the processing table 100. A support frame 101 is provided at the center of the upper end of the processing table 100, and a mounting frame 103 is provided at the upper end of the processing table 100. The coating mechanism 200 includes a mounting plate 201 fixedly mounted on the lower end of the mounting frame 103. A hollow rotating shaft 202 is rotatably mounted on the lower end of the mounting plate 201, and a guide plate 203 is mounted on the end of the hollow rotating shaft 202. A cavity 206 is provided inside the guide plate 203. An air inlet pipe 208 communicating with the cavity 206 is installed on the guide plate 203. The air inlet pipe 208 is located inside the hollow rotating shaft 202, and the upper end of the hollow rotating shaft 202 extends out of the hollow rotating shaft 202. A U-shaped plate 214 is provided on the guide plate 203. A telescopic rod 219 is installed at the lower end of the U-shaped plate 214. A spray head 217 is installed at the end of the telescopic rod 219. Connecting rods 220 are symmetrically arranged on the side ends of the telescopic rod 219. Universal ball bearings 221 are installed at the ends of the connecting rods 220. This utility model can adapt well to the complex curved surface of the machine body shell, allowing the spray head 217 to spray evenly. Secondly, it can quickly dry the coating during spraying. Compared with manual hand-painting, it effectively avoids the problem of uneven spraying and improves the coating quality and efficiency.

[0022] Specifically, the support frame 101 has a circular top view, and its inner diameter gradually decreases from bottom to top, giving it an overall birdcage shape. This unique shape allows the support frame 101 to stably support the drone's fuselage from the inside, ensuring the components remain in place during the coating process and providing a foundation for precise coating.

[0023] Furthermore, a driven gear 210 is provided on the hollow rotating shaft 202, and a first motor 211 is provided on the upper end of the mounting plate 201. A driving gear 209 is installed at the end of the output shaft of the first motor 211, and the driving gear 209 is meshed and connected to the driven gear 210. The operation of the first motor 211 can make the driving gear 209 rotate. Because the driving gear 209 is meshed and connected to the driven gear 210 on the hollow rotating shaft 202, the hollow rotating shaft 202 is rotated. When the hollow rotating shaft 202 rotates, the guide plate 203 installed at its end also rotates. The rotation of the guide plate 203 can make the spray head 217 installed at the lower end of the U-shaped plate 214 make circular motion around the UAV parts.

[0024] It is worth noting that the air intake pipe 208 extends above the mounting plate 201. An air pump 212 is mounted on the mounting bracket 103, and an air supply pipe 213 is mounted on the air pump 212. The end of the air supply pipe 213 is rotatably connected to the air intake pipe 208 via a sealed bearing. The air pump 212 can supply air to the air intake pipe 208 through the air supply pipe 213. The air enters the guide plate 203 through the air intake pipe 208. The air intake pipe 208 is located inside the hollow rotating shaft 202, with its upper end extending out of the hollow rotating shaft 202. The end of the air supply pipe 213 is rotatably connected to the air intake pipe 208 via a sealed bearing. This design ensures stable air supply even during the rotation of the hollow rotating shaft 202.

[0025] It is worth mentioning that the guide plate 203 is curved downwards along its long axis. Positioning grooves 204 are provided at both the front and rear ends of the guide plate 203. Limiting sliders 218 are symmetrically arranged on the inner wall of the U-shaped plate 214, and these sliders 218 are slidably installed within the positioning grooves 204. The cooperation between the positioning grooves 204 on the guide plate 203 and the limiting sliders 218 on the inner wall of the U-shaped plate 214, along with the meshing connection between the drive gear 215 and the meshing teeth 205, ensures smooth and precise sliding of the U-shaped plate 214 on the guide plate 203, guaranteeing the accuracy and stability of the spray head 217's position adjustment.

[0026] It is worth noting that the lower end of the guide plate 203 is symmetrically provided with meshing teeth 205, and the drive gear 215 is symmetrically rotatably installed in the U-shaped opening of the U-shaped plate 214. The rear end of the U-shaped plate 214 is provided with a second motor 216. The main shaft of the second motor 216 is connected to the shaft of the drive gear 215. The drive gear 215 is meshed with the meshing teeth 205. The lower end of the guide plate 203 is provided with air vents 207 at equal intervals. The air vents 207 are located between the meshing teeth 205. The second motor 216 at the rear end of the U-shaped plate 214 is started. The main shaft of the second motor 216 drives the drive gear 215 to rotate. Since the drive gear 215 is engaged with the meshing teeth 205 symmetrically arranged at the lower end of the guide plate 203, the U-shaped plate 214 will slide along the guide plate 203. The guide plate 203 is arranged in an arc shape that bends downward along the long axis. This allows the U-shaped plate 214 to drive the spray head 217 to move along the arc trajectory of the guide plate 203, thereby adjusting the position of the spray head 217 in the vertical direction. In addition, with the telescopic rod 219 and the universal ball bearing 221, it can adapt to the complex curved shape of the UAV parts. During the spraying process, the gas delivered to the cavity 206 by the air inlet pipe 208 can be discharged from the air outlet 207, thereby drying the sprayed coating.

[0027] Working Principle: This embodiment provides a coating device for drone parts suitable for complex curved surfaces. In use, the drone fuselage shell to be coated is placed on the support frame 101 of the processing table 100. Due to the special shape of the support frame 101, it can well adapt to the shape of the fuselage shell, providing stable support to the fuselage shell from the inside (e.g., ...). Figure 6 The first motor 211 is started, and its output shaft drives the drive gear 209 to rotate. Because the drive gear 209 meshes with the driven gear 210 on the hollow shaft 202, the hollow shaft 202 rotates. When the hollow shaft 202 rotates, the guide plate 203 installed at its end also rotates. The rotation of the guide plate 203 causes the spray head 217 installed at the lower end of the U-shaped plate 214 to make a circular motion around the drone parts. The second motor 216 at the rear end of the U-shaped plate 214 is started, and its main shaft drives the drive gear 215 to rotate. The 5 meshing teeth 205, symmetrically arranged at the lower end of the guide plate 203, engage with the U-shaped plate 214. The limiting slider 218 on the inner wall of the U-shaped plate 214 is slidably installed in the positioning grooves 204 opened at the front and rear ends of the guide plate 203. Therefore, the rotation of the drive gear 215 causes the U-shaped plate 214 to slide along the guide plate 203. The guide plate 203 is arranged in a downward-curving arc along its long axis, which allows the U-shaped plate 214 to drive the spray head 217 to move along the arc trajectory of the guide plate 203, thereby adjusting the position of the spray head 217 in the vertical direction. During the adjustment process, the universal ball bearing 221 contacts the outer surface of the drone shell. When the spray head 217 contacts the concave curved surface of the shell, its own weight causes the telescopic rod 219 to extend, allowing the spray head 217 to extend forward and approach the outer surface of the shell. When the outer surface of the shell is a convex arc surface, the universal ball bearing 221 can compress and retract the telescopic rod 219, allowing the spray head 217 to adapt to the complex curved shape of the drone parts. Combined with the rotation of the guide plate 203, the entire drone fuselage shell can be sprayed. During the coating process, the air pump 212 on the mounting bracket 103 is activated. The air pump 212 supplies air to the air inlet pipe 208 through the air supply pipe 213. The air inlet pipe 208 is located in the air... The hollow shaft 202 is inserted inside and extends out of the hollow shaft 202. The end of the air supply pipe 213 is rotatably connected to the air inlet pipe 208 through a sealed bearing. This design ensures stable air supply during the rotation of the hollow shaft 202. The gas enters the cavity 206 in the guide plate 203 through the air inlet pipe 208, and then exits through the air outlet 207 equidistantly opened at the lower end of the guide plate 203. The discharged gas can dry the sprayed area. Since the universal ball bearings 221 are located on both sides of the exhaust, the coating in contact with the universal ball bearings 221 is in a dry state. The spray drying setting can improve the processing efficiency of UAV parts.
