[0042] A paint spraying control system is provided in the controller 11, and the paint spraying control system includes a data acquisition module and a control module. The data acquisition module includes a gas monitoring module, an image receiving submodule and an analysis submodule. The gas monitoring module is electrically connected to gas detector 1 and gas detector 2, and the image receiving submodule is electrically connected to the camera.

The paint spraying control submodule is electrically connected to the first nozzle 16 and the second nozzle 18, the speed control submodule is electrically connected to the blower 21, and the rotation control submodule is electrically connected to the first drive.

[0044] The paint spraying control system includes the following specific operation steps:

[0045] Step 1: When spray painting is required, place the wheel hub on the tray 14, push it into the paint box 10, and close the sliding door 3;

[0046] In this step, the sliding door 3 is closed to prevent gas from flowing into the workshop during the subsequent painting work, thereby affecting the working environment.

[0047] Step 2: Start the painting assembly and paint the wheel hub;

[0048] Specifically, the first drive is started to drive the support rod 13 to rotate, the wheel hub is controlled to rotate slowly and uniformly, and then the first pump body 9 is turned on to pump the paint liquid in the storage tank 2 into the central shell 4 through the transmission pipe 8. At the same time, the second pump body and the third pump body are started to spray the paint liquid in the central shell 4 and the storage tank 2 respectively through the first nozzle 16 and the second nozzle 18 onto the surface of the wheel hub to achieve painting.

[0049] It should be noted that the first drive may be a motor, and the first pump body 9, the second pump body and the third pump body may be liquid pumps.

[0050] Step 3: After painting, determine whether the paint surface is uniform. When the paint surface is uniform, turn on the blower 21 and the electronically controlled valve 23 to transport the toxic gas in the paint spray box 1 to the gas filter 6 to filter the toxic gas.

[0051] Step 4: When the paint smell in the paint spray box 1 decreases, open the sliding door 3 and push the support assembly into the paint baking box 10 to bake paint on the wheel hub.

[0052] Specifically, when the wheel hub enters the paint box 10, the rolling door is opened and unrolled, the paint box 10 becomes closed, the paint unit in the paint box 10 is opened to start painting, and when the paint is finished, the support assembly is pushed out of the paint box 10, and the fan 22 is turned on to dissipate heat for the wheel hub.

[0053] It should be added that rolling doors are prior art and will not be described in detail herein.

[0054] Step 3 includes the following specific steps:

[0055] Step 3-a: After the painting is finished, the first drive rotation and the painting assembly are suspended, and the camera is turned on to take a picture of the wheel surface and transmit it to the image receiving submodule to determine whether the wheel paint surface is uniform and whether there is toxic gas flowing into the workshop during painting;

[0056] Specifically, a photo of a uniform wheel hub surface is input into the image receiving submodule, and the real-time image is compared with the original image. If they match, it means that the paint surface of the wheel hub surface is uniform; if they do not match, it means that the paint surface of the wheel hub surface is uneven.

[0057] When the paint surface of the wheel hub is uneven, it means that there is a difference in the spraying amount of the first nozzle 16 and the second nozzle 18, which affects the uniformity of the paint surface. At this time, the signal is transmitted to the rotation sub-module, and the rotation speed of the first drive is reduced through the rotation control sub-module. Then the signal is transmitted to the first nozzle 16 and the second nozzle 18 through the paint control sub-module to increase the spraying amount of the first nozzle 16 and the second nozzle 18. At the same time, the linear drive is controlled to start, driving the sliding plate 12 to move left and right in the paint spray box 1, so that the paint liquid can better contact with the surface of the wheel hub and improve the spraying quality.

[0058] If the wheel hub paint surface is still uneven after spraying, the paint spraying box 1 is stopped and the staff takes out the wheel hub and sprays the paint manually.

[0059] Furthermore, during painting, the toxic gas content in the paint spray box 1 is detected in real time by gas detector 1 and the external toxic gas content is detected by gas detector 2, and transmitted to the gas monitoring submodule to determine whether the toxic gas is leaking during painting.

[0060] Specifically, when the toxic gas content in the paint spray box 1 is increasing and the gas detector 2 detects that the external toxic gas content is low, it means that there is no leakage of toxic gas in the paint spray box 1. When the toxic gas content in the paint spray box 1 is increasing and the gas detector 2 detects that the external toxic gas content is high, it means that there is leakage of toxic gas in the paint spray box 1, but the leakage degree is low. At this time, the paint spraying component is suspended, and the blower 21 is started to pump the external gas into the paint spray box 1, and then the internal toxic gas is discharged into the gas filter 6 through the air outlet pipe 7 to filter the toxic gas and discharge the toxic gas in the paint spray box 1 at the same time until the toxic gas content in the paint spray box 1 becomes low, and then continue the painting work to avoid excessive leakage of toxic gas and affect the working environment. When the toxic gas content does not increase or decreases during painting, when the gas detector 2 detects that the external toxic gas content is high, it means that the leakage degree of toxic gas in the paint spray box 1 is high, indicating that the sealing of the paint spray box 1 is insufficient and needs to be repaired by staff.

[0061] Through the above steps, not only the quality of painting is guaranteed during painting, but also the leakage of toxic gas can be monitored in real time to avoid the leakage of toxic gas during painting, so that the working environment meets environmental protection standards.

[0062] Step 3-b: When the wheel hub paint surface is sprayed evenly, the toxic gas in the paint spray box 1 is discharged to prevent the toxic gas from affecting the workshop environment when the paint spray box 1 is opened;

[0063] Specifically, the step of discharging the toxic gas in step 3-a is repeated until the toxic gas content in the paint spray box 1 becomes low, and then the sliding doors 3 on both sides of the paint spray box 1 are opened to remove the support assembly.

[0064] Furthermore, while cleaning the toxic gas in the paint spray box 1, repeat step three-a to determine the leakage degree of the toxic gas. If the leakage degree of the toxic gas is large, the signal is transmitted to the speed control submodule to control the displacement of the blower, increase the gas circulation speed, and make the toxic gas quickly discharge from the paint spray box 1, thereby further avoiding the leakage of toxic gas.
