Description

喷漆材料颜色自动定制系统及方法System and method for automatic color customization of spray paint material 技术领域technical field
本发明涉及车辆喷漆领域，尤其涉及一种喷漆材料颜色自动定制系统及方法。The invention relates to the field of vehicle painting, in particular to an automatic color customization system and method for painting materials.
背景技术Background technique
汽车喷漆是指给汽车表面上一层漆达到保护汽车的效果。汽车喷漆一般用烘烤漆。在汽车制造厂，车架、车壳焊接完成，下一道工序就是喷漆。形式有普通漆、金属漆、珠光漆。汽车喷漆工序：刮腻子、打磨、喷漆等。Car spray painting refers to the effect of applying a layer of paint to the surface of the car to protect the car. Auto paint generally uses baking paint. In the automobile factory, the frame and shell are welded, and the next process is painting. Forms are ordinary paint, metallic paint, pearl paint. Automobile painting process: putty scraping, sanding, painting, etc.
普通漆是最常见的汽车用漆，出现得也最早，十多年前人们接触到的汽车多是用的这种油漆，它的特点是成本低廉，工艺简单，但其光泽度不太好，表面硬度也不高，特别容易刮花。所以在轿车上已经很少使用，即便有也是低档次的车型，最多的是用在货车和客车上，不过使用这类油漆的汽车在价格上有优势。Ordinary paint is the most common car paint, and it appeared the earliest. Most of the cars that people came into contact with more than ten years ago used this paint. It is characterized by low cost and simple process, but its gloss is not very good. The surface hardness is not high, especially easy to scratch. Therefore, it has been rarely used in cars, even if there are low-grade models, most of which are used in trucks and passenger cars, but cars using this type of paint have an advantage in price.
金属漆，又叫金属闪光漆，是流行的一种汽车面漆。在它的漆基中加有微细的铝粒。光线射到铝粒上后，又被铝粒透过气膜反射出来。因此，看上去好像金属在闪闪发光一样。这种金属闪光漆，给人们一种愉悦、轻快、新颖的感觉，所以十分普遍。改变铝粒的形状和大小，就可以控制金属闪光漆膜的闪光度。在金属漆的外面，还加有一层清漆予以保护。Metallic paint, also known as metallic flash paint, is a popular automotive finish. It has fine aluminum particles added to its base. After the light hits the aluminum particles, it is reflected by the aluminum particles through the gas film. Therefore, it looks as if the metal is sparkling. This kind of metallic glitter paint gives people a pleasant, light and novel feeling, so it is very common. By changing the shape and size of the aluminum particles, you can control the sparkle of the metallic glitter paint film. On the outside of the metallic paint, a layer of varnish is added for protection.

以下将结合附图对本发明的实施方案进行描述，其中：Embodiments of the present invention will be described below with reference to the accompanying drawings, wherein:

具体实施方式detailed description
下面将参照附图对本发明的喷漆材料颜色自动定制系统及方法的实 施方案进行详细说明。Embodiments of the system and method for automatically customizing the color of spray paint materials of the present invention will be described in detail below with reference to the accompanying drawings.
喷涂施工前，喷枪和相关设备应清洁，并处于正常的工作状态，检查喷枪是否产生理想的喷雾形状。理想的喷雾形状应对称，雾化粒度分布均匀，边缘清晰，喷雾形状边缘之外只能有少量漆雾存在，低的雾化气压有助于产生正确、均匀的喷雾形状，减少反弹和过喷。Before spraying, the spray gun and related equipment should be clean and in normal working condition. Check whether the spray gun produces the ideal spray shape. The ideal spray shape should be symmetrical, with uniform atomization particle size distribution and sharp edges. Only a small amount of paint mist exists outside the edge of the spray shape. Low atomization air pressure helps to produce correct and uniform spray shapes, reducing bounce and overspray .
正确喷涂的轨迹与工件表面保持垂直。喷涂时根据被涂面角度，喷枪与喷涂表面的距离一般为15～30cm。要获得更湿、色深和较厚的涂层，距离可近些；要获得更干、色浅和较薄的涂层，距离可远些。The trajectory of the correct spray is kept perpendicular to the workpiece surface. When spraying, according to the angle of the surface to be coated, the distance between the spray gun and the sprayed surface is generally 15-30cm. For a wetter, darker, and thicker coat, go closer; for a drier, lighter, and thinner coat, go further.
然而，如果喷漆操作不当或者选择材料有误，喷漆后的车辆全身效果不佳，容易在车辆补漆后出现车检无法通过的情况。However, if the painting operation is improper or the material is selected incorrectly, the whole body effect of the painted vehicle will be poor, and it is easy to fail the vehicle inspection after the vehicle is repainted.
为了克服上述不足，本发明搭建了一种喷漆材料颜色自动定制系统及方法，能够有效解决相应的技术问题。In order to overcome the above deficiencies, the present invention builds an automatic color customization system and method for spray paint materials, which can effectively solve the corresponding technical problems.
