[0002] For metal parts and products that have been processed, a paint surface is currently used for rust prevention, aesthetics, and other reasons. Water-based acrylic acid in modified acrylic acid is widely used because it uses water as a dispersion medium, reduces the emission of harmful substances, and is relatively environmentally friendly.

[0003] In the factory, because the workpieces after painting are not cured and dried immediately, the storage space of the semi-finished workpieces needs to be considered. Therefore, if the paint surface cannot dry quickly, it will occupy more factory space. For this reason, manufacturers often accelerate the drying by controlling the paint baking temperature. However, the current process is generally fixed, and the modified acrylic component, content, and usage amount used each time are not necessarily the same, and the process matching is poor, which affects the paint quality and production efficiency.

DETAILED DESCRIPTION

[0054] The following is combined with Figure 1-5 This application is described in further detail.

[0055] The embodiment of the present application discloses a system for preparing modified acrylic baking varnish.

[0056] Reference Figure 1 The modified acrylic paint preparation system includes a controller, which is data-connected to the control system of the paint baking device and is configured to execute the following logic:

[0057] S1, initialization process configuration logic;

[0058] S2, paint logic;

[0059] S3, dynamic process adjustment logic.

[0060] The purpose of this application is to improve the matching degree of paint, improve the paint quality and production efficiency by anchoring the process during the initial paint baking, recording variables, and comparing the variables in real time during subsequent use to dynamically adjust the process.

[0061] The above S1, initialization process configuration logic, includes:

[0062] Obtain the categories and components of modified acrylic paints and generate paint formulas;

[0063] The standard paint baking conditions are verified according to the paint formula request, and the paint baking process is generated after the verification is completed.

[0064] Among them, the modified acrylic paint example: acrylic resin and water-based amino resin are used as the main materials, and the ratio is 3±0.4:1±0.3, and then deionized water, ammonia neutralizers that can adjust the pH value to 7-8, and other functional additives are mixed in and mixed evenly. According to the mixed functional additives such as flash rust agent, pigment, or according to the specific ratio of the two resins, various paint categories are formed, and the components are clearly defined. In this application, the categories and components of the paint are uploaded by the staff when they use each category of paint for the first time. After the data is uploaded to form a formula, the program system executing this application requests the staff to verify the paint conditions through the corresponding user interface in the form of pop-up windows. The paint conditions here, such as temperature and duration, can complete the initialization process anchoring after verification.

[0065] S2, paint logic, which includes:

[0066] Obtaining operation data of the paint baking device; examples of the paint baking device include: a paint baking room, a paint baking furnace; the operation data includes voltage, current, and set target temperature of the electric heater; wind speed of the exhaust fan; temperature measured by a temperature sensor in the paint baking chamber, etc.

[0067] If the current state is feeding, the category of the paint is obtained, and the matching paint formula is called to initiate the formula verification process;

[0068] Determine the paint baking conditions according to the formula verification results (search historical records), and control the paint baking device based on the paint baking conditions.

[0069] Reference Figure 2 and Figure 3 In this application, a display and a key panel are installed at the entrance and exit of the paint baking device, and they are connected to the controller of this application. The controller loads and runs the corresponding degree; the controller connects the paint baking device with an electrical signal to exchange data. The above formula verification is displayed on the display, and the staff completes the verification before / after closing the entrance and exit of the paint baking device to avoid production accidents; after verification, the controller sends the paint baking temperature and duration to the control system of the paint baking device, which instructs it to execute the paint baking action.

[0070] S3, dynamic process adjustment logic, which includes:

[0071] If the current painting session matches the standard painting condition approval session, that is, it is the first painting of a certain type of paint, then the humidity parameter in the painting device when the painting logic is executed is obtained, and a humidity change curve is generated based on the execution time. It can be understood that the curve is a descending curve, and the curve is the change information of the reference variable under the anchoring condition.

[0072] If the current painting session does not match the standard painting condition approval session, that is, it is not the first time to paint a certain type of paint, then:

[0073] Get the humidity parameters in the paint baking device when the paint baking logic is executed;

[0074] Compare the current humidity parameter with the historical humidity parameter in the humidity change curve based on the execution time; Example: Compare the humidity parameter at 30 minutes of paint baking with the historical humidity parameter at the 30-minute position in the humidity change curve;

[0075] If the current humidity parameter is greater than the historical humidity parameter, the paint baking time will be extended;

[0076] If the current humidity parameter is less than the historical humidity parameter, the paint baking time will be shortened.

[0077] According to the above content, the present application can record the variables of various paints during the initial painting, and call them in subsequent painting operations for comparative analysis with the current variables, and dynamically adjust the painting process according to the results, so that when the modified acrylic components, contents, and usage amounts used each time are different, the matching degree of the painting process is relatively better, thereby improving the quality of modified acrylic painting and production efficiency.

[0078] In one embodiment of the present application, the paint baking time is extended, which includes:

[0079] Obtain the paint temperature of the current paint baking device and maintain it until the current humidity parameter is equal to the historical humidity parameter;

[0080] Calculate the maintenance time T;

[0081] Correct the time in the humidity change curve with the duration T and update the paint baking time; for example: the current humidity at 27 minutes is greater than the historical humidity, the humidity at 27 minutes in the original humidity change curve is y1, and the humidity is y1 only after the current temperature is maintained for T=2 minutes, then the time of each point after 27 minutes in the humidity change curve is +2 minutes.

[0082] In one embodiment of the present application, the paint baking time is shortened, which includes:

[0083] Get the paint temperature of the current paint device;

[0084] If the current paint baking temperature is maintained until the paint baking is finished, the paint baking will be stopped when the real-time humidity parameter is equal to the humidity parameter at the end of the paint baking;

[0085] If the current paint baking temperature changes before the paint baking ends, the current humidity parameter is substituted into the humidity change curve to determine the corresponding time and calculate the remaining maintenance time of the current paint baking temperature; for example: the original temperature at the 20th to 30th minute was maintained for a total of 10 minutes, and the humidity parameter was y2 at the 8th minute; and the current humidity parameter is y2 at the 6th minute, then the remaining maintenance time = 10-8 = 2min, not 4min.

[0086] Control the execution time of the current paint temperature according to the remaining maintenance time.

[0087] According to the above settings, whether the humidity is high or low, this application can adjust the paint baking process in time; and even if the temperature changes in steps during the paint baking process, it can also be applied.

[0088] In one embodiment of the present application, a method for obtaining humidity parameters includes:

[0089] Select the air inlet of the exhaust duct of the paint spraying device (such as the paint spraying room) as the detection area;

[0090] A variable acquisition module is deployed to sample the atmosphere passing through the detection area and measure humidity parameters.

[0091] The variable acquisition module includes a temperature and humidity sensor 4, whose data is connected to the aforementioned controller or the control system of the paint baking device to transmit the measured humidity parameters back for analysis in this application.

[0092] Reference Figure 3 , 4 and Figure 5It should be noted that the above-mentioned temperature and humidity sensor is not directly installed in the detection area through a bracket, but is configured as follows: the variable acquisition module also includes an intermediate pipe 1, a heat exchange tube 2, and a detection box 3.

[0093] Among them, the middle pipe 1 includes a front air duct 11 and a rear air duct 12. One end of the front air duct 11 penetrates the outer shell of the paint baking device (paint baking room), and the other end is connected to the inner cavity of the detection box 3; the front air duct 11 is an insulation pipe, such as: wrapping insulation cotton on the outside of the pipe to reduce the interference caused by heat dissipation.

[0094] The detection box 3 is located outside the paint baking device and is a hollow structure, and the temperature and humidity sensor 4 is installed inside the detection box 3. One end of the rear air duct 12 is connected to the detection box 3 and the connection port is far away from the connection port of the front air duct 11 and the detection box 3, and the other end of the rear air duct 12 is connected to the exhaust duct of the paint baking device and is located between the exhaust air inlet and the fan.

[0095] The main body of the heat exchange tube 2 is placed in the front air duct 11, and both ends of the heat exchange tube 2 pass through the side wall of the front air duct 11. One end of the heat exchange tube 2 extends upward and is connected to the three-way pipe 21, and the other end of the heat exchange tube 2 faces downward. The other two ports of the three-way pipe 21 are respectively installed with a solenoid valve 1 22 and a solenoid valve 2 23, wherein the other end of the solenoid valve 1 22 is connected to a water source. The downward end of the heat exchange tube 2 extends through the front of the heat source of the paint baking device and bends horizontally to pass through the paint baking device. At least a section of the heat exchange tube 2 close to the heat source of the paint baking device is a copper tube.

[0096] The electromagnetic valve 1 22, the electromagnetic valve 2 23 and the temperature and humidity sensor 4 are respectively connected to the above-mentioned controller or the controller of the paint baking device.

[0097] According to the above settings, the humidity parameter of the present application is collected in the detection box 3, and the temperature is also collected at the same time; on this basis, the present application can make the following settings:

[0098] If the current temperature is lower than the temperature corresponding to the standard paint baking condition, the solenoid valve 23 is opened to allow the air in the heat exchange tube 2 to rise, and the heat generated by the heat source of the paint baking device is directly guided to the front air duct 11 to heat the gas entering the detection box 3.

[0099] If the current temperature remains lower than the corresponding temperature in the standard paint baking condition for t1 time after the solenoid valve 23 is opened, a heat source temperature increase instruction is sent to the paint baking device and maintained for t1 time, wherein t1 is a value set by the staff, and t1 time is the time sufficient for the heat from the heat source to be transferred to the front air duct 11; the temperature increase instruction can be to increase the temperature to the corresponding temperature in the standard paint baking condition.

[0100] If the current temperature is higher than the corresponding temperature in the standard paint baking condition, the solenoid valve 22 is opened, and water flows into the heat exchange tube 2 to cool the air in the front air duct 11.

[0101] According to the above settings, the present application can make the temperature during humidity detection relatively consistent, so as to reduce the error in the detection result caused by different gas expansion amounts caused by different temperatures; at the same time, the above settings, whether it is the gas flow or the temperature rise in the intermediate pipe 1, are the design reuse of the paint baking device, so the use and maintenance costs are also lower.

[0102] Reference Figure 2 In one embodiment of the present application, the following settings are made to clarify the status of the paint baking device:

[0103] Establishing a visual system; wherein the visual system includes a camera, which is mounted on a bracket on the ground or on the outer wall of the paint baking device, with the lens facing the entrance and exit of the paint baking device;

[0104] Establish data connection between the visual system and the preset controller, and establish data connection between the controller;

[0105] The controller recognizes the image fed back by the visual system and obtains the current state based on the recognition result.

[0106] On the one hand, the above setting makes it more convenient to obtain the status of the paint baking device in this application without manual input; on the other hand, it also serves as a safety supervision tool for the paint baking device; at the same time, it also provides more support for optimizing the dynamic adjustment process of this application, specifically:

[0107] Putting one workpiece into a paint booth for painting and putting a hundred workpieces into the paint booth will produce significantly different amounts of water vapor before the end of painting, especially closer to the beginning. Therefore, the above method is only suitable for painting equal or approximate amounts of workpieces, which lacks flexibility in production. Therefore, this application further estimates the paint surface area correction analysis process based on the visual system.

[0108] The controller of the present application is also configured as:

[0109] Acquire images of the material during feeding;

[0110] Identify the workpiece to be painted based on the image and calculate the paint area;

[0111] The current paint baking area is calculated and compared with the paint baking area of ​​the approved session under standard paint baking conditions to obtain a ratio, and the current humidity parameters are corrected based on the ratio.

[0112] Example: The database stores the individual paint surface areas of three types of workpieces, A, B, and C. When workers deliver workpieces to the paint baking device through a paint baking rack or a cart, they are identified to determine which type of workpiece they are, and the number of workpieces delivered is determined based on image counting or directly based on the identified paint baking rack capacity; number * individual area = total paint baking area; assuming the ratio is 1.2, the current humidity is considered to be * 1.2.

[0113] According to the above settings, this application can more flexibly meet the diverse production and processing needs of manufacturers; at the same time, the process does not require manual counting of the number of workpieces, so it is more convenient to use.

[0114] It is understandable that in order to obtain clear images, in addition to using high-definition cameras, there can also be multiple cameras, distributed from top to bottom at various locations at the entrance and exit of the paint booth, so as to obtain clear images from multiple perspectives for analysis and recognition.

[0115] In another implementation of the present application, based on the above-mentioned diversified paint needs, the staff will set different exhaust rates for the exhaust of the paint room or the controller of the paint room will change the wind speed. It is known that the air intake of the detection box 3 of the present application relies on the exhaust design of the paint room, which will cause the humidity detection to be disturbed. Therefore, the present application also performs wind speed stabilization processing on the variable acquisition module.

[0116] The wind speed stabilization setting is achieved by setting a stabilization mechanism, specifically:

[0117] Reference Figure 4 The first method is to fix a baffle 31 in the detection box 3, and the baffle 31 faces the connecting port between the front air duct 11 and the detection box 3; the temperature and humidity sensor 4 is installed on the back of the baffle 31; that is, the temperature and humidity sensor 4 is placed in the leeward vortex area, so that the detected gas is more stable.

[0118] Reference Figure 5 , the second type, the front air duct 11 is divided into a thin tube section and a thick tube section, the front tube section has a heat exchange tube 2 inside, there are multiple thick tube sections and they are in parallel relationship, the parallel thick tube sections are connected to the thin tube section in front, and are connected to the detection box 3 in the back; the thick tube section of any front air duct 11 is installed with a solenoid valve 3 5; the controller is electrically connected to the solenoid valve 3 5 and binds each valve to the corresponding pipe diameter; the controller pre-stores the matching relationship between the wind speed and the pipe diameter. During the painting process, the solenoid valve 3 5 of the corresponding pipe diameter is switched on according to the real-time wind speed, that is, based on the principle of continuity equation to change the front and rear pipe diameters, the gas flow rate entering the detection box 3 is adjusted. The reason for this setting is that the air flow method of the detection box 3 in this application does not design an independent extraction and pumping mechanism.

[0119] In another embodiment of the present application, the above content is considered to be aimed at the humidity in the paint room, and at least a part of the paint room needs to be supplemented with air from the outside during the paint baking process. The existing air intake treatment mostly considers that the paint itself is heated and dried, so basically only the intake air is purified and dust is filtered without considering the ambient humidity; this has little effect on the aforementioned application in dry areas, but in southern my country, especially in rainy weather, it will obviously affect the determination of the paint baking time, so the controller is also electrically connected to a dehumidification mechanism, which can be a duct dehumidifier or a duct dehumidifier, and the supplementary gas entering the paint baking device is allowed to pass through the dehumidifier first through the pipeline series connection.

[0120] The controller configuration is:

[0121] Record the outlet humidity of the dehumidification mechanism during the standard paint baking conditions corresponding to each paint baking process, and define it as the anchoring ambient humidity;

[0122] When approving the session under non-standard paint baking conditions, the dehumidification mechanism is controlled for environmental humidity consistency based on the anchored environmental humidity and the current outlet air humidity; for example: if the current outlet air humidity is greater than the anchored environmental humidity, the dehumidification mechanism is controlled to start up, and the target humidity is set to the anchored environmental humidity.

[0123] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
