Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) manufacturing equipment technology, specifically to a fuselage spraying device for UAV manufacturing. Background Technology

[0002] In the manufacturing process of drones, fuselage painting is a key step in ensuring appearance quality, improving corrosion resistance, and extending service life. However, existing fuselage painting equipment has the following shortcomings in practical applications:

[0003] First, traditional equipment often uses a single fixed platform, allowing only one drone body to be coated at a time. Furthermore, the fixed structure cannot accommodate drone shells of different sizes and shapes, necessitating frequent fixture changes and resulting in low production efficiency. Second, traditional spraying equipment has a fixed nozzle position or can only move in one direction, making it difficult to cover irregular curved surfaces of the drone body. This easily leads to localized missed areas and uneven coating thickness, affecting appearance and protective performance. Third, during the spraying process, the paint remains stationary in the material tank for extended periods, easily causing component stratification or sedimentation, resulting in inconsistent coating color and adhesion, reducing product qualification rates. Finally, the paint mist generated during spraying lacks effective collection and purification devices, polluting the workshop environment and endangering the health of operators, failing to meet environmental protection production requirements. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fuselage spraying equipment for UAV manufacturing that is flexible in fixing, uniform in spraying, stable in coating, environmentally friendly and safe, and easy to monitor.

[0005] The technical solution adopted by this utility model is as follows: This utility model provides a fuselage spraying device for UAV manufacturing, including a base, a protective cover, a fixing mechanism, a spraying mechanism, and a purification mechanism. The base is provided with an installation groove, the protective cover is located on the top of the base, and a sealing door is hinged to the protective cover. The fixing mechanism is located on the top of the base and inside the protective cover. The spraying mechanism and the purification mechanism are both located on the protective cover. The fixing mechanism includes a fixing seat, a first motor, a fixing frame, and a fixing platform. The fixing seat is located on the top of the base and has a groove. The first motor is located in the groove, and the fixing frame is located on the output shaft of the first motor. The first motor can drive the fixing frame to rotate. The fixing platform is provided with a rotating shaft, and the fixing platform is rotatably mounted on the fixing frame via the rotating shaft. A gear is sleeved on the rotating shaft, and a gear ring is sleeved on the fixing seat. The gear ring meshes with the gear. When the fixing frame rotates, the gear rolls along the gear ring, causing the fixing platform to rotate. The fixing platforms are arranged in a circular array of several groups, and each group of the fixing platforms is provided with a fixing unit for fixing the UAV shell to be sprayed.

[0006] Preferably, the fixing unit includes a bidirectional threaded rod and a slider. The fixing platform is provided with a cavity and a groove communicating with the cavity. The bidirectional threaded rod is rotatably disposed in the cavity. The slider is threadedly sleeved onto the bidirectional threaded rod. Two sets of sliders are symmetrically arranged. Each set of sliders is provided with a fixing clamp. The fixing clamp is slidably disposed in the groove for clamping the drone shell to be painted. A second motor is provided on the fixing platform. One end of the bidirectional threaded rod is connected to the output shaft of the second motor. The second motor drives the bidirectional threaded rod to rotate, causing the slider and the fixing clamp to move in opposite directions or in the opposite direction, thereby achieving clamping and fixing of drone shells of different sizes.

[0007] Preferably, the spraying mechanism includes a material tank, a material pump, an annular tube, and a spraying hose. The material tank is located in an installation groove, the material pump is located on a protective cover, and a feed pipe is connected between the material tank and the material pump inlet. The annular tube is located at the top of the protective cover, and a discharge pipe is connected between the annular tube and the material pump outlet. The spraying hose is located on the annular tube and extends into the protective cover. A nozzle is provided at the end of the annular tube. Several groups of spraying hoses are arranged in a ring array. The center of the spraying hose array and the center of the fixed platform array are both coincident with the rotation axis of the fixed frame to ensure that the nozzles spray the machine body on each fixed platform evenly. A reciprocating lifting unit is provided on the protective cover, and the nozzle is located on the reciprocating lifting unit.

[0008] Preferably, the reciprocating lifting unit includes a cylinder and a lifting frame. The cylinder is mounted on the protective cover, the lifting frame is mounted on the output shaft of the cylinder, and the nozzle is mounted on the lifting frame. The cylinder can drive the lifting frame to move the nozzle reciprocally up and down, adapting to the spraying needs of different machine heights.

[0009] Preferably, the material tank is equipped with a stirring unit, which includes a stirring shaft and stirring blades. The stirring shaft is rotatably disposed inside the material tank, and the stirring blades are disposed on the stirring shaft. The material tank is equipped with a third motor, and one end of the stirring shaft is connected to the output shaft of the third motor. The third motor can drive the stirring blades to rotate to prevent the coating from settling.

[0010] Preferably, the purification mechanism includes a fan, a fan hood, an exhaust pipe, and a purification box. The purification box is installed in the mounting groove. The air inlet of the fan is connected to the air outlet of the purification box. The exhaust pipe is connected to the air inlet of the purification box. The fan hood is installed on the protective cover and connected to the exhaust pipe. The purification box is equipped with a filter screen and an activated carbon filter layer. After the fan is started, the paint mist in the protective cover enters the purification box through the fan hood and the exhaust pipe. After the filter screen filters out impurities and the activated carbon filter layer adsorbs harmful gases, the mist is discharged, thus achieving environmental purification.

[0011] In a further preferred embodiment, the sealing door is provided with a transparent observation window, which facilitates real-time observation of the spraying process inside the protective cover without the need to stop the machine for inspection. At the same time, the sealing door can prevent paint mist from overflowing after it is closed, thus improving the sealing performance.
