Description

Multi-color surface paint treatment method

technical field

The invention relates to a multi-color surface paint treatment method, which is mainly designed for the coating of paint materials with different colors to be formed on the predetermined parts of the base paint material. Laser etching is used to form the engraved grooves for the second coating. It replaces the manual work and troublesome inconvenience caused by the conventional sticker sticking and isolation reservation method, so that the surface paint treatment operation can be implemented consistently, so as to improve its operation efficiency and operation quality, and endow it with excellent industrial utilization value.

Background technique

At present, in order to obtain the appearance texture and material protection function of general workpieces, paint coating treatment is often carried out on the surface, and the coating treatment method of the surface paint usually adopts different construction techniques such as spraying and electroplating to coat the paint After coating on the surface of the workpiece, it is baked and dried at a predetermined temperature, so that the paint can be fixed on the surface of the workpiece to form a protective layer, and the overall texture and aesthetics can be improved by the color of the paint.

As far as the existing workpiece surface paint coating structure is concerned, most of them are painted with monochrome paint. Although the expected material protection function of the workpiece can be achieved, the appearance can only be changed through the color change of the paint. Achieving visual changes virtually limits its industrial use value. In order to solve the monotonous visual effect of its single-color paint, the industry adopts color-separated paint coating, and uses different-color paints on the predetermined parts of the workpiece to carry out predetermined patterns. Graphic coating, in order to present eye-catching color difference contrast effect, with the transformation of different color paints, endow it with more style change effects, so that in addition to achieving the protection function of the workpiece material, it can also have the overall visual appearance and Enhanced texture.

Taking the general electro-deposition coating technology as an example, please refer to Figures 1 and 2. When the surface of the workpiece is to be painted with multi-color surface paint, usually the surface of the workpiece 10 is to be painted different from the base paint 20. The pre-determined part of the graphic surface paint 30 of the color is first attached with a pre-determined type sticker 11 or film according to its secondary coating requirements, and then the first base surface is carried out according to the existing electro-deposition coating technology. Paint 20 coating operation, so that the base surface paint 20 can be evenly coated on the surface of the workpiece 10, after drying and shaping, the workpiece 10 is taken away from the work area, and the pre-attached sticker 11 or film is torn off manually , with the tearing off of the stickers 11 or films, the reserved unpainted area 12 will be formed at the predetermined position of the base surface paint 20. At this time, the second time of graphic representation must be carried out by electro-deposition coating technology. Paint 30 coating operations, so that its graphic surface paint 30 can be evenly coated on the aforementioned unpainted area 12, so that the surface of the workpiece 10 can be completely coated by the base surface paint 20 and the graphic surface paint 30, and finally Carry out the second drying and finalizing operation again, finish the multi-color surface paint coating operation of workpiece accordingly, utilize the base surface paint 20 of its different color and luster and graphic surface paint 30 to form eye-catching color difference contrast, highlight its desire to be on the surface of workpiece 10 Graphical effects presented to enhance the overall visual variability and texture.

From the above construction method, because it adopts the method of attaching stickers or films to reserve the unpainted area required for the second graphic paint coating, and this operation must be carried out manually, so the operation will Derived labor costs, and its sticker tearing operation cannot be carried out on the processing line, resulting in the inability to achieve consistent implementation of its two coating operations, which virtually affects its overall operating efficiency, resulting in high production costs And when the sticker or film is torn off, it may damage the smoothness of its edge, which will affect the quality of its subsequent secondary coating, and even form defective products. As far as industrial utilization is concerned, it is necessary to try to improve Solve for improvement.

In addition, in the surface paint coating operation of the workpiece, some operators will first design the graphics and texts to be formed in an embossed shape, and after the first painting operation is completed, the workpiece will be removed from the work area. Manually remove the surface paint of the embossed graphics to reveal the material of the workpiece, and then carry out the second painting operation. Such a method cannot be implemented consistently in the entire operation process. At the same time It is also a non-ideal operation mode to increase the labor cost and affect the production efficiency due to the method of manually removing the surface paint.
