[0002] Aircraft maintenance includes repair, assembly and debugging of aircraft airframe structure and accessories, test flights and troubleshooting, aircraft repair technology management, and field maintenance. The feasibility of an aircraft and ensuring its safety are prerequisites and necessary conditions for its use. In aircraft maintenance, the spraying of the engine can delay the rust and corrosion of its surface metal, which is also an important task to ensure aircraft safety.

[0003] In aircraft maintenance, painting is an important task. It not only affects the aircraft's appearance but also directly impacts its corrosion resistance and service life.

[0004] In traditional spray painting operations, the lack of necessary barriers causes paint to scatter everywhere, resulting in unnecessary waste of paint, environmental pollution, and unnecessary cleaning difficulties for workers. Utility Model Content

[0005] In view of this, the present invention provides a collection device for aircraft maintenance spraying, which can automatically collect and reuse paint that splashes everywhere during the spraying operation. This solves the problem that in traditional spraying operations, the lack of necessary obstruction causes paint to scatter everywhere, resulting in unnecessary waste of paint, as well as environmental pollution and unnecessary cleaning difficulties for workers.

[0006] To address the aforementioned technical problems, this utility model provides a collection device for aircraft maintenance painting. The collection device is mounted on a painting robot located on the upper part of the chassis. The painting robot is equipped with a nozzle, and a collection mechanism is fitted around the outside of the nozzle. The collection mechanism includes a baffle fitted around the outside of the nozzle. The collection device also includes a fixed frame mounted on the painting robot. The fixed frame has a transfer tank connected to a paint storage tank and a recycling tank connected to the transfer tank. The transfer tank is connected to the nozzle via a flexible hose, and the recycling tank is connected to the baffle via a rubber tube. An adsorption cover is provided at the end of the rubber tube passing through the baffle. This utility model can achieve centralized adsorption, collection, recycling, and reuse of paint that is scattered during the painting process through a collection mechanism located outside the nozzle of the painting robot. This avoids the unnecessary waste of paint caused by the lack of necessary obstruction during traditional painting operations, which leads to paint scattering everywhere, environmental pollution, and unnecessary cleaning difficulties for workers. The operation is safer, more convenient, and more environmentally friendly.

[0007] A spray pump is installed on the fixed frame. The suction port of the spray pump is connected to the outlet of the transfer tank, and the spray nozzle of the spray pump is connected to one end of the hose.

This utility model can automatically draw paint from the paint storage tank through the transfer tank and spray it into the hose and nozzle through the spray nozzle of the spray pump, so as to achieve efficient spraying operation on the parts to be sprayed and make the operation more convenient.

[0008] A sealing disc is provided between the baffle and the nozzle, and a flexible tube passes through the sealing disc. This utility model can achieve a firm seal between the connection between the baffle and the nozzle through the sealing disc, preventing paint from splashing out from the gap between the baffle and the nozzle.

[0009] The mounting frame is also equipped with a liquid suction pump. The inlet of the liquid suction pump is connected to the other end of the rubber tube, and the outlet of the liquid suction pump is connected to the inlet of the recycling bin. This utility model can use the suction force of the liquid suction pump to suck the splashes of paint during the spraying operation into the recycling bin through the adsorption cover at the end of the rubber tube.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figure 1-3As shown: This embodiment provides a collection device for aircraft maintenance painting, including a painting robot 200 mounted on the upper part of the chassis 100. The painting robot 200 is equipped with a nozzle 300, and a collection mechanism 400 is fitted around the nozzle 300. The collection mechanism 400 includes a baffle 410 fitted around the nozzle 300. The baffle 410 has a frustum-shaped structure where the opening at the end near the painting robot 200 is larger than the opening at the other end, to ensure a larger blocking range. The collection device also includes a mounting frame 420 mounted on the painting robot 200. The mounting frame 420 has a transfer tank 430 connected to a paint storage tank via a connecting hose 450 and a recovery tank 440 connected to the transfer tank 430. The nozzle 300 is connected to the collection bin 440 via a flexible hose 450, and the baffle 410 is connected to the collection bin 440 via a rubber tube 460. An adsorption hood 470 is provided at the end of the rubber tube 460 that passes through the baffle 410. The adsorption hood 470 has a structure where the lower opening is larger than the upper opening. This is to ensure a larger adsorption range. This utility model can achieve centralized adsorption, collection, recycling and reuse of the paint that flies and scatters during the spraying operation by using a collection mechanism 400 set on the outside of the nozzle 300 of the spraying robot 200. This avoids the unnecessary waste of paint caused by the lack of necessary obstruction during the traditional spraying operation, which leads to paint scattering everywhere, environmental pollution and unnecessary cleaning difficulties for workers. The operation is safer, more convenient and more environmentally friendly.

[0023] According to one embodiment of the present invention, such as Figure 1-3 As shown, a spray pump is installed on the fixed frame 420. The spray pump is a plunger pump. The suction port of the spray pump is connected to the liquid outlet of the transfer tank 430. The spray nozzle of the spray pump is connected to one end of the hose 450. The other end of the hose 450 is connected to the liquid inlet of the nozzle 300. This utility model can automatically draw the paint from the paint storage tank through the transfer tank 430 and spray it into the hose 450 and the nozzle 300 through the spray nozzle of the spray pump, so as to achieve efficient spraying operation on the parts to be sprayed and make the operation more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a sealing disc 480 is provided between the baffle 410 and the nozzle 300, and a flexible hose 450 passes through the sealing disc 480. Both the sealing disc 480 and the flexible hose 450 are made of rubber. This utility model can achieve a firm seal between the connection between the baffle 410 and the nozzle 300 through the sealing disc 480, preventing paint from splashing out from the gap between the baffle 410 and the nozzle 300.

[0025] A suction pump is also installed on the fixed frame 420. The inlet of the suction pump is connected to the other end of the rubber tube 460, and the outlet of the suction pump is connected to the inlet of the recycling bin 440. This utility model can use the suction force of the suction pump to suck the splashes of paint during the spraying operation through the adsorption cover 470 at the end of the rubber tube 460 into the recycling bin 440. Finally, the paint enters the transfer bin 430 through the recycling bin 440 for recycling and reuse, which is more energy-saving and environmentally friendly.

[0026] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the outlet of the recycling tank 440 is connected to the return port of the transfer tank 430, and the inlet of the transfer tank 430 is connected to the paint storage tank.

[0027] The painting robot 200 is a six-axis manipulator. This invention can achieve comprehensive painting operations on the parts to be painted through the six-axis manipulator, resulting in better painting effect and higher efficiency.

[0028] The four corners of the lower part of the chassis 100 are respectively equipped with a wheel 500. Each wheel 500 has a motor connected to its drive shaft. The output shaft of the motor is connected to the shaft of the wheel 500 through a rotating sleeve.

[0029] How to use this utility model:

[0030] First, it needs to be clarified that the collection device involved in this utility model is mainly used for effectively blocking and efficiently recycling paint that splashes or drips during spraying operations. This utility model takes the spraying process in aircraft fuselage maintenance as an example to describe its usage method in detail. Before that, it needs to be clarified that since the core improvement of this utility model is the blocking and recycling of paint splashes during spraying operations, the focus is on explaining its principle in detail. The control of the motion trajectory and related principles of the spraying robot 200 and the Meyer wheel 500 will not be elaborated on. When it is necessary to spray the area to be sprayed, the Meyer wheel 500 is first started, moving the chassis 100 to a suitable position. (Before this, the motion trajectory of the spraying robot 200 and the Meyer wheel 500 needs to be planned and its motion program needs to be entered into the controller inside the chassis 100. The controller controls the motion trajectory of the Meyer wheel 500 and the spraying robot 200.) Then, the spraying robot 200 is started to work. The spraying pump and suction pump are activated simultaneously, allowing the spraying robot 200 to perform automatic spraying. The spraying pump draws paint from the paint storage tank into the transfer tank 430, then into the hose 450, and finally into the nozzle 300 for spraying. During spraying, splashed paint is sucked into the recovery tank 440 by the suction of the suction pump, passing through the adsorption hood 470 and the rubber hose 460. The paint then flows back to the transfer tank 430 for recycling, making it more energy-efficient and environmentally friendly. This invention uses a collection mechanism 400 located on the outside of the nozzle 300 of the spraying robot 200 to collect and reuse the paint that flies and scatters during the spraying process. This avoids the unnecessary waste of paint caused by the lack of necessary obstruction during traditional spraying operations, which also leads to environmental pollution and unnecessary cleaning difficulties for workers. The operation is safer, more convenient, and more environmentally friendly.

[0031] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
