Description
Technical Field
[0001] The utility model relates to the technical field of waterborne coating for automobile exterior panels, and particularly relates to a waterborne coating device for automobile exterior panels. Background Art
[0002] Waterborne coating of automobile exterior panels is a process before the automobile exterior panels leave the factory. After the automobile exterior panels are ground and polished, it is necessary to perform operations of coating and painting, so that the automobile exterior panels have specific colors. However, due to the characteristics of waterborne coatings, the traditional waterborne coating has stronger fluidity and is not easy to color. A large amount of coating will flow along the surface of the exterior panel, and the flowing coating cannot be collected, resulting in a large waste of coating.
[0003] The existing waterborne coating of automobile exterior panels cannot collect a large amount of excess coating, resulting in a large waste of coating. For example, a primer spraying device for left and right automobile panels disclosed in CN221183295U includes a spray booth, a base, a conveying mechanism, and a spraying mechanism. A conveying mechanism for conveying left and right automobile panels is arranged in the chamber of the spray booth, which eliminates the need for manual feeding or discharging and improves efficiency. The conveying mechanism includes a guide rail, a slider, and a carrier. The carrier includes a rotating shaft, a carrier plate, and brackets. There are multiple brackets and they are distributed in a circumferential array at the upper end of the carrier plate, so that one carrier can install multiple left and right automobile panels at the same time, improving the spraying efficiency. Moreover, the carrier is set to be rotatable. During the spraying process, the left and right automobile panels are driven by the carrier to rotate at a high speed, so that all the left and right automobile panels on the same carrier can be sprayed with primer. Then, in cooperation with the first driving device to control the height of the nozzle, all positions on the outer side of all left and right automobile panels can be sprayed with primer to ensure the spraying effect. However, this solution does not solve the problems of how to collect and reuse the excess paint, and a large amount of paint will be wasted.
[0004] Therefore, it is necessary to invent a waterborne coating device for automobile exterior panels to solve the above problems. Summary of the Utility Model

A circulating pump is connected to the side of the aggregate tank. The end of the circulating pump is connected to a feeding pipe. An aqueous feeding pipe is connected to the feeding pipe. A plurality of linear nozzles are evenly installed on the aqueous feeding pipe. The aqueous feeding pipe is driven by a half-axis motor.
[0007] Preferably, the rotating shaft of the half-axis motor is installed in the auxiliary shaft, and the auxiliary shaft penetrates through the coating device main body.
[0008] Preferably, a plurality of drainage grooves are provided, and the distances between the plurality of drainage grooves are all equal, and the depth of each drainage groove is the same.

[0023] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.
[0024] The present utility model provides an aqueous coating device for an automotive exterior trim panel as shown in Figures 1-3 , which includes a main body 1 of the coating device, a drainage groove 2, a fixed pile 3, an aggregate tank 4, and a linear nozzle 9. The main body 1 of the coating device is inclined, and a drainage groove 2 is provided on its surface. An automotive exterior trim panel main body 12 can be placed on the fixed pile 3. An aggregate tank 4 is arranged below the bottom end of the drainage groove 2. A filter plate 5 is detachably installed in the aggregate tank 4. A circulation pump 6 is connected to the side of the aggregate tank 4. The end of the circulation pump 6 is connected to a material delivery pipe 7. An aqueous delivery pipe 8 is connected to the material delivery pipe 7. A plurality of linear nozzles 9 are uniformly installed on the aqueous delivery pipe 8. The aqueous delivery pipe 8 is driven by a half-axis motor 10.
[0025] Start the circulation pump 6 to deliver the aqueous coating in the aggregate tank 4 towards the aqueous delivery pipe 8 and the linear nozzles 9, and rotate within the flat angle range of the half-axis motor 10, and spray the aqueous coating onto the surface of the automotive exterior trim panel main body 12 through the plurality of linear nozzles 9 for coating.
[0026] The rotating shaft of the half-axis motor 10 is installed in the auxiliary shaft 11, and the auxiliary shaft 11 penetrates through the main body 1 of the coating device. A plurality of drainage grooves 2 are provided, and the distances between the plurality of drainage grooves 2 are all equal, and the depth of each drainage groove 2 is the same. The filter plate 5 is arranged at half of the height of the aggregate tank 4, and the filter plate 5 is fixed to the aggregate tank 4 through a card slot. The filter plate 5 can be replaced with different mesh diameters. The circulation pump 6 is connected between the aggregate tank 4 and the material delivery pipe 7. The aggregate tank 4 is filled with aqueous coating.
[0027] The function of the circulation pump 6 is to continuously transport the water-based paint in the aggregate tank 4 into the linear nozzle 9 and spray it onto the automotive exterior panel body 12 for painting. The excess paint will flow along the drainage groove 2 into the aggregate tank 4, and after being filtered by the filter plate 5, it can be reused by the circulation pump 6, saving paint.
[0028] There are multiple linear nozzles 9, and the distances between the multiple linear nozzles 9 are all equal. Moreover, the linear nozzles 9 are evenly distributed on the inner side of the N-shaped water delivery pipe 8. The inner gear of the half-axis motor 10 is a semi-tooth gear, and the rotation range of the half-axis motor 10 is within 180°.
[0029] The function of the linear nozzle 9 is to ensure that the water-based paint can be sprayed linearly and is in vertical contact with the surface of the automotive exterior panel body 12, ensuring uniform spraying and preventing accumulation and unevenness.
[0030] The working principle of the present utility model:
[0031] Refer to the attached Figures 1-3 When using the present utility model, first transport the automotive exterior panel body 12 to be painted to the fixed pile 3. After fixing the automotive exterior panel body 12, the spraying operation can be started.
[0032] Refer to the attached Figures 3-5 When using the present utility model, the water-based paint in the aggregate tank 4 is transported into the feed pipe 7 and the water delivery pipe 8 by the circulation pump 6, and then transported into the linear nozzle 9 and linearly sprayed onto the surface of the automotive exterior panel body 12 from the linear nozzle 9.
[0033] Start the half-axis motor 10 to rotate the water delivery pipe 8 within a range of 180°. Stop when the water delivery pipe 8 rotates from one side of the painting device main body 1 to the other side to complete one painting. When rotating again, rotate from the other side to one side, and so on, until the surface of the automotive exterior panel body 12 is completely painted.
[0034] During the painting process, the excess water-based paint will be collected by multiple drainage grooves 2 and transported into the aggregate tank 4. After passing through the filter plate 5, it can be remixed with the paint in the aggregate tank 4 and transported again from the circulation pump 6.
