[0019] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can implement the present application according to the description.

[0020] It should be noted that the experimental methods in the following embodiments are conventional methods, and the reagents and materials are commercially available unless otherwise specified; in the description of the present application, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0021] As Figure 1 and Figure 2The utility model provides a kind of automobile primer coating system, it include: liquid supply system 2, quantitative system 3, coating device 5 and industrial robot 4;The coating device 5 is installed in the end of the industrial robot 4;The liquid supply system 2 includes air handling unit 210, cleaning solvent pressure tank 220, primer pressure tank 230;The air handling unit 210 is connected with gas source, to filter and dry gas source, the air handling unit 210 is connected with the cleaning solvent pressure tank 220 by first air pipe 241, the cleaning solvent pressure tank 220 is connected with the primer pressure tank 230 by second air pipe 242 and first liquid pipe 251 respectively;The primer pressure tank 230 is connected with the quantitative system 3 by second liquid pipe 252, the quantitative system 3 is connected with the coating device 5 by third liquid pipe 253;First air pipe 241, second air pipe 242, first liquid pipe 251, second liquid pipe 252 and third liquid pipe 253 are all provided with control valve.

[0022] In this technical solution, the air handling unit 210 is used to provide clean and dry compressed air for the system. The dry air filtered by multiple layers enters the cleaning solvent pressure tank 220 through the first air pipe 241. The dry air mixed with cleaning solvent is then delivered to the primer pressure tank 230 through the second air pipe 242, serving as the pressure source for the primer pressure tank 230. This effectively prevents the primer in the primer pressure tank 230 from solidifying and precipitating due to moisture.

[0023] During coating operation, the control valves on the second liquid pipe 252 and the third liquid pipe 253 are opened. The primer in the primer pressure tank 230 is input into the quantitative system 3 through the second liquid pipe 252. The output of the quantitative system 3 is controlled to enter the coating device 5, and then the coating device 5 uniformly coats the workpiece 1. The quantitative system 3 can be a servo quantitative cylinder commonly used in the field. The speed of the servo motor in the servo quantitative cylinder is controlled by the industrial robot 4 to adjust the output.

[0024] During cleaning operation, dry air is first introduced into the primer flow pipe through the first air pipe 241 and the second air pipe 242 to blow the residual liquid in the pipe into the waste liquid box. Then the control valves on the first liquid pipe 251, the second liquid pipe 252, and the third liquid pipe 253 are opened. The cleaning solvent in the cleaning solvent pressure tank 220 enters the primer pressure tank 230 through the first liquid pipe 251 and cleans the equipment and pipes along the primer flow path. The cleaned waste liquid enters the waste liquid box from the coating device 5.

[0025] In another technical solution, as shown in Figure 2 The quantitative system 3 is also connected with the primer pressure tank 230 through a circulating pipeline 260, and a circulating valve is arranged on the circulating pipeline 260 close to the quantitative system 3.

[0026] When there is no coating operation, the automatic circulating mode can be started, and the control system 1 is set to stop production for more than n minutes and circulate for m minutes according to the production status and production mode; when there is coating operation, the automatic circulating mode is paused, and the circulating valve is closed. In the automatic circulating mode, the quantitative system 3 first draws primer through the second liquid pipeline 252, then closes the control valve on the second liquid pipeline 252, opens the circulating valve, and the quantitative system 3 discharges the liquid back to the primer pressure tank 230 through the circulating valve. The control valve on the second liquid pipeline 252 is arranged close to the quantitative system 3; through automatic circulation, the liquid in the pipeline is in a flowing state, which effectively prevents the primer from precipitating and accumulating. When cleaning, the automatic circulating pipeline 260 can also be opened; the cleaning solvent from the quantitative system 3 enters the coating device and the circulating pipeline 260, and after returning to the primer pressure tank 230, it is discharged into the waste liquid tank 232.

The primer in the third liquid pipeline 253 passes through the first on-off needle valve 521 and the first connecting pipe 524 in sequence and reaches the brush 540. The linear bearing 523 and the spring 522 constitute a brush floating mechanism, in the primer coating process, the first on-off needle valve 521, the first connecting pipe 524 and the brush 540 fall under the action of their own gravity, the spring 522 installed on the upper part of the linear bearing 523 ensures that the pressing force on the brush 540 is consistent in the coating process by providing an opposite elastic force, so that the primer coating width is consistent and the primer quality is ensured.
