[0027] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-7 As shown, this embodiment provides a parts painting production line for train carriage maintenance, including: a foundation 10, a preheating chamber 20, a primer center 30, a topcoat center 40, and a moving device. The preheating chamber 20 is disposed on the foundation 10 and is adapted to heat the carriage 1 located inside the preheating chamber 20. The primer center 30 is disposed on the foundation 10 and spaced apart from the preheating chamber 20. The topcoat center 40 is disposed on the foundation 10 and located on the side of the primer center 30 away from the preheating chamber 20. The topcoat center 40 is spaced apart from the primer center 30. The moving device is movably disposed on the foundation 10 and is adapted to carry the carriage 1 and drive the carriage 1 to move.

[0029] In some embodiments, the foundation 10 serves as the supporting base for the entire painting production line. The foundation 10 can provide a stable installation platform. The preheating chamber 20 is set on the foundation 10. The preheating chamber 20 is used to preheat the train carriage 1 entering the painting production line. Preheating can melt any debris that may be frozen on the carriage 1, such as frost or moisture, to prepare for subsequent painting operations and ensure better painting results.

[0030] The primer center 30 is also set on the foundation 10. The primer center 30 is a certain distance away from the preheating chamber 20. The primer center 30 is the main area for primer spraying and drying, and provides preliminary anti-corrosion and aesthetic treatment to the surface of the carriage 1. The topcoat center 40 is set on the foundation 10. The topcoat center 40 is located on the side of the primer center 30 away from the preheating chamber 20. The topcoat center 40 is also a certain distance away from the primer center 30. The topcoat center 40 is the area for topcoat spraying and drying, and provides the carriage 1 with the final appearance color and gloss. The moving device is movably set on the foundation 10. The moving device is used to carry and drive the train carriage 1 to move between the preheating chamber 20, the primer center 30 and the topcoat center 40. The moving device ensures that the carriage 1 can pass through each processing area in the predetermined process flow sequence.

[0031] It is understandable that after the maintenance of train carriage 1 is completed, some parts of train carriage 1 need to be repainted. The parts painting production line of this application can realize the automatic painting process of train carriage 1 after maintenance. Specifically, the moving device can be supported at the bottom of carriage 1, and then the moving device moves to drive carriage 1. The moving device moves along a preset path so that carriage 1 passes through the preheating chamber 20, the primer center 30, and the topcoat center 40 in sequence. When carriage 1 passes through the primer center 30, the primer center 30 can perform primer spraying on some parts. When carriage 1 passes through the topcoat center 40, the topcoat center 40 can perform topcoat spraying on some parts. Compared with manual spraying, the painting efficiency is improved, and the operator's contact with the painting environment is avoided, ensuring the health of the personnel. At the same time, it can avoid the unstable painting quality and waste caused by manual operation, saving costs while ensuring the painting quality of carriage 1.

[0032] According to the present invention, a parts painting production line for the maintenance of train carriage 1 realizes automatic painting of parts after the maintenance of train carriage 1 is completed. Compared with manual painting operation, the parts painting production line of this application has high painting efficiency and good quality for carriage 1, while avoiding paint waste. Of course, it also reduces labor costs and avoids operators from being exposed to the painting environment, thus protecting the health of operators.

[0033] According to some embodiments of the present invention, the primer center 30 includes a primer spraying chamber 31, and two movable first painting components 311 are provided in the primer spraying chamber 31. The two first painting components 311 are respectively located on both sides in the width direction of the primer spraying chamber 31, and the two first painting components 311 are respectively adapted to move along the length, width and height directions of the primer spraying chamber 31 to spray paint the outer side of the carriage 1.

[0034] In some embodiments, two movable first painting components 311 are provided in the primer spraying chamber 31. The two first painting components 311 are respectively located on both sides of the primer spraying chamber 31 in the width direction, that is, the two first painting components 311 are respectively located on the left and right sides of the carriage 1, so as to fully paint the outer side of the carriage 1. The two first painting components 311 are respectively adapted to move along the length, width and height directions of the primer spraying chamber 31, so that the first painting components 311 can flexibly adjust the painting position to ensure that each part that needs to be painted on the outer side of the carriage 1 can be uniformly painted.

[0035] Understandably, the mobility of the first painting assembly 311 enables it to adapt to train carriages 1 of different sizes and shapes, improving the versatility and flexibility of the painting production line. Moreover, automated painting operations reduce manual intervention, increase painting speed and production efficiency. Of course, by reducing the need for manual painting, labor costs can be reduced, painting quality can be improved, rework and scrap rates can be reduced, and production costs can be further reduced.

[0036] According to some embodiments of the present invention, the primer center 30 further includes a primer drying chamber 32, which is located on the side of the primer spraying chamber 31 away from the preheating chamber 20. The primer drying chamber 32 is adapted to blow hot air into the carriage 1 located in the primer drying chamber 32.

[0037] In some embodiments, the primer drying chamber 32 is located on the side of the primer spraying chamber 31 opposite to the preheating chamber 20, meaning the primer drying chamber 32 is located in the next process step after the primer spraying operation is completed. By setting the primer drying chamber 32 after the primer spraying chamber 31, hot air is used to dry the primer-coated carriage 1, ensuring that the primer dries quickly in a short time, preparing it for subsequent topcoat spraying operations, and improving the production efficiency of the entire painting production line. Of course, the quickly dried primer can avoid quality problems such as sagging and blistering during the subsequent topcoat spraying process, improving the overall quality of the painting.

[0038] According to some embodiments of the present invention, the primer center 30 further includes a dust blowing chamber 33, which is disposed between the primer spraying chamber 31 and the preheating chamber 20. The dust blowing chamber 33 is provided with a nozzle 331 that is suitable for moving along the length, width and height of the dust blowing chamber 33. The nozzle 331 moves and blows air onto the carriage 1 located in the dust blowing chamber 33 to blow off the dust on the surface of the carriage 1.

[0039] It is understandable that the dust blowing chamber 33 is located between the primer spraying chamber 31 and the preheating chamber 20. That is, after the carriage 1 is preheated in the preheating chamber 20, the carriage 1 will first enter the dust blowing chamber 33 to clean the surface dust, and then enter the primer spraying chamber 31 to spray the primer.

[0040] The main function of the dust blowing chamber 33 is to blow air onto the surface of the carriage 1 through its nozzles 331 to remove dust and debris, providing a clean surface for subsequent primer spraying. Specifically, the dust blowing chamber 33 is equipped with a cantilever 332, the extension direction of which is parallel to the width direction of the dust blowing chamber 33. The cantilever 332 is located at the top of the carriage 1 and is adapted to move along the length direction of the dust blowing chamber 33. A robotic arm 333 is movably connected to the cantilever 332 and is adapted to move along the extension direction of the cantilever 332. Simultaneously, a nozzle 331 is provided at the free end of the robotic arm 333, which can drive the nozzle 331 to move along the height direction of the dust blowing chamber 33. Thus, the nozzle 331 can move along the length, width, and height directions of the dust blowing chamber 33 and blow air onto the surface of the carriage 1, ensuring that the nozzle 331 can fully cover all surfaces of the carriage 1 and that dust is thoroughly blown off.

[0041] It is worth mentioning that the dust blowing chamber 33 ensures that the surface of the carriage 1 is clean before the primer is applied, avoiding the influence of dust and debris on the adhesion of the primer, thereby improving the coating quality.

[0042] According to some embodiments of the present invention, the topcoat center 40 includes a topcoat spraying chamber 41, and two movable second painting components 411 are provided in the topcoat spraying chamber 41. The two second painting components 411 are respectively located on both sides in the width direction of the topcoat spraying chamber 41, and the two second painting components 411 are respectively adapted to move along the length, width and height directions of the topcoat spraying chamber 41 to spray paint the outer side of the carriage 1.

[0043] It is understandable that two movable second painting components 411 are provided in the topcoat spraying chamber 41. The two second painting components 411 are located on both sides of the width direction of the topcoat spraying chamber 41, that is, the two second painting components 411 are located on the left and right sides of the carriage 1, so as to fully paint the accessories that need to be painted on the outer side of the carriage 1.

[0044] The two second painting components 411 are respectively adapted to move along the length, width and height of the topcoat spraying chamber 41, so that the second painting components 411 can flexibly adjust the painting position to ensure that each accessory on the outer side of the carriage 1 that needs to be painted can be uniformly painted.

[0045] It should be noted that the multi-dimensional movement capability of the two second painting components 411 enables them to precisely control the painting position and thickness, thereby improving the uniformity and quality of the topcoat spraying.

[0046] According to some embodiments of the present invention, the topcoat center 40 further includes a topcoat drying chamber 42, which is located on the side of the topcoat spraying chamber 41 away from the primer center 30. The topcoat drying chamber 42 is adapted to blow hot air into the carriage 1 located inside the topcoat drying chamber 42.

[0047] In some embodiments, the topcoat drying chamber 42 is located on the side of the topcoat spraying chamber 41 away from the primer center 30, that is, the topcoat drying chamber 42 is located at the next process step after the topcoat spraying operation is completed. The main function of the topcoat drying chamber 42 is to blow hot air into the compartment 1 located therein to accelerate the drying process of the topcoat, thereby preparing for subsequent inspection, packaging or delivery processes, and improving the production efficiency of the entire painting production line.

[0048] According to some embodiments of the present invention, the topcoat center 40 further includes a protective chamber 43, which is located between the topcoat spraying chamber 41 and the primer center 30. Two moving trolleys 431 are arranged inside the protective chamber 43. The two moving trolleys 431 are respectively located on both sides of the protective chamber 43 in the width direction. The moving trolleys 431 are adapted to move along the length direction of the protective chamber 43, and the moving trolleys 431 are provided with a manned platform 432 adapted to move along the height direction of the protective chamber 43.

[0049] In some embodiments, the protective chamber 43 is located between the topcoat spraying chamber 41 and the primer center 30. That is, after the primer spraying and drying are completed, the protective chamber 43 will first enter the protective chamber 43 for necessary protective treatment, and then enter the topcoat spraying chamber 41 for topcoat spraying.

[0050] Specifically, inside the protective chamber 43, the operator can stand on the manned platform 432 and then control the moving trolley 431 to move along the length of the protective chamber 43, while simultaneously controlling the manned platform 432 to move along the height of the protective chamber 43. Thus, the operator can use the moving trolley 431 to be positioned at various locations on both sides of the carriage 1, thereby facilitating the operator to protect the parts of the carriage 1 that do not require topcoat spraying (by laying anti-paint cloth or newspaper, etc.) and preventing these parts from being accidentally sprayed during the topcoat spraying process.

[0051] Therefore, the design of the trolley 431 allows operators to perform protective work at different heights, improving the flexibility and efficiency of the operation.

[0052] According to some embodiments of the present invention, a first waiting space 12 is provided between the primer center 30 and the preheating chamber 20, and / or a second waiting space 13 is provided between the primer center 30 and the topcoat center 40.

[0053] In some embodiments, a first waiting space 12 is provided between the primer center 30 and the preheating chamber 20. The first waiting space 12 provides a temporary parking location for the carriage 1 waiting to enter the primer center 30 for primer spraying after the preheating chamber 20 (20) has completed preheating treatment. In other embodiments, a second waiting space 13 is provided between the primer center 30 and the topcoat center 40. The second waiting space 13 provides a temporary parking location for the carriage 1 waiting to enter the topcoat center 40 for topcoat spraying after the primer center 30 has completed primer spraying and drying treatment. In still other embodiments, a first waiting space 12 is provided between the primer center and the preheating chamber 20, and a second waiting space 13 is provided between the primer center 30 and the topcoat center 40.

[0054] Understandably, the setup of the first waiting bay 12 and the second waiting bay 13 ensures the smooth flow of carriage 1 between various processes, reduces waiting time, and improves production efficiency. Moreover, the setup of the first waiting bay 12 and the second waiting bay 13 allows for adjustment of the rhythm and sequence between processes according to actual production needs, enhancing production flexibility. Of course, the first waiting bay 12 and the second waiting bay 13 can also serve as buffer zones to absorb fluctuations and uncertainties in the production process, reducing production risks caused by process mismatches.

[0055] According to some embodiments of the present invention, a track 11 is provided on the top of the foundation 10. The track 11 passes through the preheating chamber 20, the primer center 30 and the topcoat center 40. The moving device cooperates with the track 11 and is adapted to move along the extension direction of the track 11.

[0056] In some embodiments, the track 11 is set on top of the foundation 10 and passes through the preheating chamber 20, the primer center 30 and the topcoat center 40. That is, the track 11 is the main transport path of the entire painting production line. The carriage 1 will pass through the preheating, primer spraying and topcoat spraying processes in sequence along this path.

[0057] The moving device cooperates with the track 11. Specifically, the moving device is designed to be able to move on the track 11, that is, the moving device is adapted to move along the direction from the preheating chamber 20 to the topcoat center 40, thereby driving the carriage 1 to flow between the various processes.

[0058] Understandably, the above setup reduces the need for manual transfer of carriage 1, improves production efficiency, and reduces the workload of manual transfer of carriage 1, thereby reducing labor costs. Of course, the cooperation between track 11 and the moving device ensures that carriage 1 can pass through each process accurately and stably, improving the accuracy of production.

[0059] According to some embodiments of the present invention, the mobile device includes two AGV trolleys 50, which are respectively adapted to cooperate with the bottom ends of the carriage 1.

[0060] In some embodiments, the mobile device includes two AGV trolleys 50 (AGV (Automated Guided Vehicle) is a vehicle that can automatically travel along a preset path). The two AGV trolleys 50 are respectively located at both ends of the bottom of the carriage 1, so that both ends of the carriage 1 can be supported, thereby ensuring the support stability and transportation stability of the carriage 1.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0062] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
