Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The invention will be described in detail below with reference to the drawings in connection with embodiments.
"vehicle customization" refers to the manufacture of automobiles to meet their individual needs according to the unique needs and preferences of the customer. This trend has been directed to changing aspects of the appearance, performance, interior trim, function, and accessories of automobiles. This customized concept becomes particularly important in "street view vending carts" because these vehicles are designed as mobile business units that offer a variety of goods or services. These vehicles often require personalized appearance and color customization to appeal to customers and to accommodate different sales scenarios.
However, there are a number of technical problems and challenges in conventional vehicle custom painting processes. Prior to the production of custom products, it is often necessary to provide a simulated paint effect map for customer selection, but ensuring that the color of the vehicle or component is consistent with the simulated paint is often a challenging task during the actual paint process. This is because conventional custom painting of vehicles typically relies on experience and skill of the operator, who must adjust the spray parameters, such as spray pressure, spray speed, and drying time, based on experience, but this is susceptible to interference from personal subjective factors, resulting in spray errors. In addition, conventional coating methods have difficulty in precisely controlling the spray parameters during actual coating, and often waste a large amount of pigment and other resources. Multiple attempts and adjustments to the spraying process can reduce production efficiency, waste time and human resources, and increase production costs. Therefore, there is an urgent need to design a treatment method for custom product simulation coating to solve these technical problems.
In some embodiments of the present application, referring to fig. 1, the present embodiment provides a processing method for custom product simulation coating, including:
s100: and collecting the chromaticity data S0 of the workpiece to be machined, and determining initial machining conditions according to the chromaticity data S0.
S200: and acquiring initial chromaticity data S1 of the initial workpiece according to the initial processing conditions, comparing the chromaticity data S0 with the initial chromaticity data S1, and judging whether to adjust the initial processing conditions according to the comparison result. When s1=s0, it is determined that the initial machining condition satisfies the machining requirement, the initial machining condition is not adjusted, and the operation is continued with the initial machining condition. When S1 is not equal to S0, the initial processing condition is judged to not meet the processing requirement, and the initial processing condition is adjusted.
S300: when the initial processing conditions are determined to be adjusted, the spraying thickness H0 of the initial workpiece is collected, the spraying thickness H0 of the initial workpiece is compared with the pre-processing thickness H0 of the workpiece to be processed, and the initial processing conditions are adjusted to be first processing conditions according to comparison results.
S400: and collecting coating characteristics of the initial workpiece, judging whether to carry out secondary adjustment on the first processing condition according to the coating characteristics, and acquiring the adjusted first processing condition.
S500: and acquiring first color data S2 of the workpiece to be processed under the adjusted first processing condition, respectively comparing the first color data S2, the initial color data S1 and the color data S0, and determining a final processing condition according to the comparison result.
Specifically, collecting the chromaticity data S0 of the workpiece to be processed for preprocessing is the start point of the entire flow, which provides specific information of a desired color. The acquisition of S0 is the basis of personalized customization, and the formulated color is ensured to be accurate and error-free. S0 represents color information expected by a user in the simulated coating, and color information is extracted through an image processing algorithm, so that the acquisition of chromaticity data can be realized. Initial processing conditions are determined based on the data of S0, this step determining initial processing conditions for painting. An initial workpiece is prepared according to initial processing conditions and initial chromaticity data S1 is acquired, and the data provides the effect of actual coating for subsequent comparison. S0 and S1 are compared to determine whether the actual coating is consistent with the simulated coating under the initial processing conditions and whether adjustment is needed. The color consistency is guaranteed, and errors in the process of starting the coating process are avoided. When the initial machining conditions are inconsistent, the initial machining conditions are required to be adjusted, and the comparison is further carried out according to the ratio of the spraying thickness H0 of the initial workpiece to the pre-machining thickness H0 of the workpiece to be machined. And adjusting the initial processing conditions according to the step-by-step comparison result to optimize the coating effect, so that the actual coating and the simulated coating are kept consistent. The step-by-step comparison comprises comparison according to the thickness of the coating and the characteristics of the coating, is favorable for optimizing the coating process, ensures uniform color and good appearance, and after the adjusted first processing condition is obtained, compares the spraying effect obtained under the adjusted first processing condition with the spraying effect under the initial processing condition and determines the final processing condition according to the comparison.
It can be understood that by continuous data acquisition, comparison and adjustment, the influence of subjective factors of operators on spraying operation is eliminated, the production efficiency is improved, and the resource waste and the production cost are reduced.
In some embodiments of the present application, a process for customizing a simulated finish of a product includes: the initial processing conditions in S100 include an initial spray pressure U0, an initial spray velocity V0, and an initial drying period T0. S300, comparing the spraying thickness H0 of the initial workpiece with the pre-processing thickness H0 of the workpiece to be processed, and adjusting the initial processing condition to be a first processing condition according to the comparison result, wherein the method comprises the following steps: and obtaining a thickness difference delta H=h0-H0 between the spraying thickness H0 of the initial workpiece and the pre-processing thickness H0 of the workpiece to be processed, and adjusting the initial spraying speed V0 according to the thickness difference delta H to obtain a first processing condition.
Specifically, in the manufacturing process of the vehicle personalized product, the initial processing conditions are determined according to the color data of the simulated painting. After the initial workpiece is obtained at the time of actual machining, it is first ensured that the thickness of the coating matches the required pre-machining thickness to achieve the desired color and coating effect. By comparing the sprayed thickness of the initial workpiece with the pre-machining thickness of the workpiece to be machined. The pre-machining thickness of the workpiece to be machined is obtained from the data simulating painting. This alignment process can produce a thickness difference that represents the difference between the actual coating thickness and the ideal expected value. Depending on the magnitude of this difference, in particular if it is outside an acceptable range, the initial spray speed is adjusted accordingly. After adjustment, the required coating thickness can be ensured in the coating process, so that the desired effect of the simulated coating can be achieved.
It can be appreciated that by monitoring and adjusting the coating thickness in real time, more accurate color control and coating quality can be achieved, coating differences are reduced, pigment and resource waste is reduced, production efficiency is improved, and time and cost are saved. In addition, the consistency of the product quality is ensured, and the manufacturing process of the personalized product of the whole vehicle is more accurate and efficient.
In some embodiments of the present application, S300 adjusts the initial spraying speed V0 according to the magnitude of the thickness difference Δh, to obtain a first processing condition, including: the first preset thickness difference delta H1, the second preset thickness difference delta H2 and the third preset thickness difference delta H3 are preset, and delta H1 < [ delta ] H2 < [ delta ] H3. The first preset speed adjustment coefficient A1, the second preset speed adjustment coefficient A2 and the third preset speed adjustment coefficient A3 are preset, and A1 is more than A2 and less than A3. And selecting a speed adjustment coefficient according to the magnitude relation between the thickness difference delta H and each preset thickness difference to adjust the initial spraying speed V0, so as to obtain a first processing condition.

It will be appreciated that thicker coatings and thinner coatings may exhibit different shades of color. This can lead to inconsistent color of the product, which is inconsistent with the simulated painting. The initial spraying speed is adjusted by presetting different thickness difference thresholds and corresponding speed adjustment coefficients, and selecting proper speed adjustment coefficients according to the relation between the actual thickness difference of the coating and the thresholds. When the thickness difference of the coating falls in different threshold ranges, different speed adjustment coefficients are adopted for adjustment so as to obtain corresponding adjusted spraying speeds. This differentiated adjustment helps to ensure consistency of the quality and color of the coating. The method for adjusting the speed of the vehicle is capable of accurately controlling the coating, ensuring that the coating of the color of the manufactured vehicle is consistent with the simulated coating, reducing waste in production, improving production efficiency and reducing cost, and can accurately adjust the spraying speed according to different coating requirements, so that production quality is improved.

The method comprises the steps of collecting coating characteristics of a workpiece to be machined, wherein the coating characteristics of the workpiece to be machined comprise desired uniformity Y0, desired smoothness J0 and desired adhesion F0. The uniformity difference Δy=y1-Y0 is obtained from the coating uniformity Y1 and the desired uniformity Y0, the finish difference Δj=j1-J0 is obtained from the coating finish J1 and the desired finish J0, and the adhesion difference Δf=f1-F0 is obtained from the coating adhesion F1 and the desired adhesion F0.

It will be appreciated that the first process condition is determined based on the thickness to ensure that the thickness of the coating conforms to the simulated coating to achieve the desired color and quality. However, the quality of the coating is affected not only by thickness, but also by uniformity, finish and adhesion factors. Even if the requirements in terms of thickness are met, the uniformity, finish and adhesion of the coating may still result in large product variations if the standards for simulated painting are not met. Thus, after the initial processing conditions are determined, the coating is further inspected for uniformity, finish, and adhesion to ensure that the coating meets the requirements in a number of respects. If there are significant differences between the desired uniformity, finish, and adhesion of the workpiece to be machined and the coating characteristics of the original workpiece, this may indicate that the original machining conditions are not meeting the product quality criteria. In this case, by making a secondary adjustment to the first process conditions, the desired coating characteristics can be better met, ensuring a more uniform, smoother coating, and better adhesion.

It will be appreciated that a multi-level pressure adjustment strategy is employed when secondary adjustments to the first process conditions are required. According to the strategy, according to the size relation among the uniformity difference delta Y, the finish difference delta J and the adhesion difference delta F of the coating, the preset n-th preset pressure adjustment coefficient Bn is selected to adjust the initial spraying pressure U0 for a plurality of times, so that various characteristics of the coating process are ensured to meet the requirements.
