Description

Technical Field

[0001] This utility model relates to the field of drone painting technology, specifically to a painting device for the surface of drone parts. Background Technology

[0002] With the rapid development of the drone industry, the surface quality requirements for its components, such as the casing, arms, and propeller supports, are increasing. Painting, as a key process in drone component production, not only effectively improves the physical properties of components, such as rust resistance and wear resistance, but is also crucial for enhancing the product's appearance consistency and quality. During the painting process, ensuring the stable fixation of components is a prerequisite for ensuring painting quality.

[0003] UAV parts are characterized by their complex irregular shapes, lightweight materials, and the use of carbon fiber composites and engineering plastics. The rigid clamping method commonly used in the prior art, as disclosed in CN213825509U, is a painting device for the surface of UAV parts. It fixes the workpiece through a clamping mechanism, but it has poor adaptability to irregular parts, is prone to surface damage, and has painting dead angles. In practical applications, the following significant defects are exposed: (1) Poor adaptability: The current rigid clamping structure has a very limited range of adjustment for clamping size and shape, making it difficult to flexibly adapt to irregular UAV parts of different specifications and curved surfaces. It often cannot achieve effective and stable clamping, and the uniformity of painting is easily affected by the loosening of parts during the painting process. (2) Easy to cause damage: When the rigid clamping part is in direct contact with the surface of lightweight and fragile parts and applies clamping force, it is very easy to cause squeezing deformation, indentation or scratches on the surface of the parts, resulting in the parts being damaged and scrapped before painting, and the production yield is low. (3) Existence of painting dead zones: The contact area between the clamping component and the parts will form a physical obstruction, making it impossible for the covered area to be covered by paint during the painting process, thus forming painting dead zones. This not only destroys the integrity of the coating, but also requires additional manual touch-up spraying, increasing process costs and time. Moreover, the color and thickness of the touch-up area are difficult to keep consistent with the overall, seriously affecting the painting quality and product consistency. Therefore, it is necessary to propose a painting device for the surface of UAV parts. Utility Model Content

[0018] This utility model relates to a painting device for the surface of drone parts, such as... Figure 1As shown, it includes a paint spray box 1, a rotating plate 2, a clamping assembly 3, and an execution assembly.

The atomizing nozzle and the horizontal drive mechanism include a drive component 8, a moving plate 9, and a guide rod 10. The drive component 8 is located at the top inside the paint spray box 1. The telescopic end of the drive component 8 is connected to the moving plate 9. The discharge pipe 44 passes through the moving plate 9 and is a telescopic flexible hose. The guide rod 10 is located at the top inside the paint spray box 1. The moving plate 9 has sliding holes that match the number of guide rods 10. Linear bearings are embedded in the sliding holes. The moving plate 9 is slidably connected to the guide rods 10 through the linear bearings.

[0020] like Figure 3 As shown, the clamping assembly 3 includes a support plate 31, a sleeve 32, a threaded rod 33, and a suction cup 34. The support plate 31 is disposed on the rotating plate 2. Multiple sleeves 32 are disposed on the top of the support plate 31. The threaded rod 33 is threadedly connected to the internal thread groove of the sleeve 32. The top end of the threaded rod 33 extends to the outside of the sleeve 32. The suction cup 34 is disposed on the top end of the threaded rod 33. The top of the suction cup 34 is provided with an arc-shaped concave surface, and the surface of the arc-shaped concave surface is provided with a micro-textured structure.

[0021] like Figure 4 As shown, the threaded connection between the sleeve 32 and the threaded rod 33 is provided with a limiting structure. The limiting structure includes an annular limiting protrusion at the bottom end of the threaded rod 33 and a limiting retaining ring at the bottom end of the inner wall of the sleeve 32. The annular limiting protrusion and the limiting retaining ring are rotated and limited. A connecting ring 5 is provided at the top outer side of the threaded rod 33, and multiple grips 6 are provided on the outer circumferential side of the connecting ring 5.

[0022] like Figure 5As shown, the support plate 31 has a cavity 35 inside, and a magnetic plate 36 is installed inside the cavity 35. The top of the support plate 31 has multiple positioning ports 37 that communicate with the cavity 35. The bottom of the sleeve 32 is provided with a positioning rod 38 that is adapted to the positioning port 37. The bottom end of the positioning rod 38 is inserted into the corresponding positioning port 37, and the bottom end of the positioning rod 38 is provided with a magnetic block 39 that is magnetically attracted to the magnetic plate 36.

[0023] The following description, in conjunction with embodiments, further illustrates the painting device for the surface of UAV components according to this utility model: Step 1: First, adjust the clamping assembly 3 according to the size and irregular shape of the drone parts to be painted. Pull the positioning rod 38 at the bottom of the sleeve 32 out of the current positioning port 37 on the placement plate 31, and then, according to the shape of the parts, reinsert the positioning rod 38 into the most suitable positioning port 37. Using the magnetic attraction between the magnetic block 39 at the bottom of the positioning rod 38 and the magnetic plate 36 in the cavity 35 of the placement plate 31, the sleeve 32 is quickly fixed in the new position, thereby adjusting the planar distribution of the multiple suction cups 34.

[0024] Step 2, Height Fine-tuning and Fixing: After completing the planar distribution adjustment, the operator holds the lever 6 on the connecting ring 5 and rotates the threaded rod 33. Through the cooperation between the threaded rod 33 and the internal thread of the sleeve 32, the suction cup 34 is driven to rise or fall, so that its working height is precisely matched with the surface contour of the part, so that all suction cups 34 can be tightly attached to the surface of the part, and the suction force of the suction cups 34 is used to achieve flexible, stable and unobstructed fixation.

[0025] Step 3, Painting Operation: Rotate the rotating plate 2 area with the fixed parts directly below the spray nozzle 45. Start the painting mechanism 4, and the material pump 41 operates, drawing paint from the storage tank 42 through the material extraction pipe 43, pressurizing it, and then conveying it to the spray nozzle 45 through the discharge pipe 44. After the paint is atomized, it is evenly sprayed from the spray nozzle 45 onto the surface of the drone parts below.

[0026] Step 4, the nozzle 45 moves to cover evenly: During the painting process, the drive component 8 pushes the moving plate 9 to move horizontally along the guide rod 10, thereby driving the nozzle 45 installed on it to move synchronously.

[0027] Step 5, Station Switching for Continuous Operation: After the first part located directly below the nozzle 45 is painted, the drive motor 7 drives the rotating plate 2 to rotate 180 degrees. This causes the painted part to move away from the painting station along with the rotating plate 2, while the clamping assembly 3, which has been fixed to the part to be painted, rotates synchronously to below the nozzle 45, ready for painting.

[0028] Step 6, Unloading and Loading Cycle: In step 5, when the painted parts are rotated by the rotating plate 2 to a position that is usually easy to access and not painted, they are removed from the suction cup 34 and a new part to be painted is quickly fixed on the clamping assembly 3 of the station.

[0029] Step 7, Continuous Production Cycle: Repeat steps 3 to 6. The painting mechanism 4 continuously paints the parts that alternately enter the painting station, while unloading and loading operations are performed at non-painting stations. The entire process does not require interruption of painting due to loading and unloading, achieving efficient batch continuous production.

[0030] This utility model relates to a painting device for drone parts. Through the combination of magnetic positioning and flexible adsorption structure, the planar position and spatial height of the suction cup 34 are quickly adjusted so that the distribution contour of the suction cup 34 accurately matches the curved surface of the irregular part. The negative pressure adsorption achieves non-destructive and omnidirectional stable clamping, reducing painting dead angles. Through the coordinated cooperation of the painting mechanism 4 and the lateral drive mechanism, the painting efficiency is significantly improved while ensuring uniform paint coverage.
