Description

Filled workpiece surface finishing method

The invention relates to a method for decorating a surface of a workpiece, in particular to a method for decorating a surface of a filled workpiece based on an anodized surface.

Many electronic technology products or daily necessities use metal as the material, and the metal material is used in addition to the basic functions of strength and durability. In addition, the metallic luster of the metal material can increase the texture of the product, and even more symbolizes the noble style. . Since the metallic luster is characterized by good light reflectivity, it is relatively easy to color, mainly because the surface porosity of the metal is relatively small, that is, the color pigment is not easily attached, and therefore it is necessary to carry out coating by electrochemical means such as electroplating. However, although plating can attach colors, it is still insufficient in deep etching and is easy to fall off.

In order to strengthen or increase the decoration of the metal surface, and still maintain the metallic luster and texture, and also have anti-oxidation and anti-wear functions such as oxidation resistance, the metal surface treatment technology is valued.

Although the prior art performs anodizing on the surface of the metal casing first, and then attaches the desired color or pattern to the printing, this manner is easy for the metal to form a wide range of coating, so it is not easy to maintain the gloss of the metal surface, and The color or pattern attached to the print is easily peeled off due to the low abrasion resistance. Moreover, the process of attaching colors and patterns to printing is cumbersome and difficult to accurately construct, and the printing color or pattern requires a large amount of construction. For a small range of coating, or a small amount of construction, it is not easy to change the flexibility and lack of change. .

In view of the problems of the prior art, the inventors believe that there should be an improved system and method for which a filled workpiece surface finishing method is designed, the steps of which at least include: forming a porous protective film by anodizing on a workpiece surface. Forming an open upward anode tube cell in the depth of the hole; then filling the colorant into the anode tube by the opening; pressurizing to dry; then the surface of the workpiece is immersed in a pore agent to the anode tube The sealing is completed; the workpiece of the finished protective film sealing process is taken out and dried. Thus, although the present invention performs the anode treatment of the workpiece surface as well, the following advantages are derived:

1. Quickly complete graphics, text, numbers or symbols.

2. Seal the graphics, text, numbers or symbols completely in the anodized layer.

3. There is no excess color residue left, and after the coating is completed, it is not necessary to remove the excess color material.

4. The amount of color material used is small, so the drying time can be greatly shortened.

5. The colorants are filled into the tracheid of the anodized layer to avoid the risk of being scraped off during use.

6. Make the lines and colors of graphics, text, numbers or symbols more detailed and clear.

The contents, features, and embodiments of the present invention will be described in the following by means of the accompanying drawings.

Referring to the first figure, the present invention relates to a method for finishing a surface of a filled workpiece, the steps of which at least include:

1. forming a porous protective film on the surface of a workpiece (preferably metal) by anodizing; forming an open upward anode tube (1) in the depth of the hole (as shown in the second figure); The job can clean the surface of the workpiece as well as chemical polishing to make the workpiece more suitable for processing. The anodizing treatment produces an oxide layer having a film thickness of about 6 μm to 15 μm on the surface of the workpiece. The oxide layer is called an anode film because the surface formed is porous and has excellent permeability.

2. Filling the colorant (2) with the opening in the anode tube (1) (as shown in the second figure); it is worth mentioning that the filling of the coloring material (2) of the present invention is selected from the pattern and the text. The outline of one of the symbols, numbers, and groups. Moreover, the color material (2) can be selected from organic color materials or non-organic color materials according to environmental protection and workpiece characteristics. Moreover, the coloring material (2) can also be selected from one of the following according to the processing requirements: photosensitive coloring material, UV coloring material, electronic coloring material, environmental protection ink, fluorescent coloring material, color changing coloring material, anti-counterfeiting coloring material. , electronic color materials and conductive color materials.

For more precise filling, the filling method of the present invention can be further injected with a needle.

3. Pressurize to dryness; drying time can range from 0.1 second to several hours. Or give a baking oven or UV (ultraviolet) illumination.

4. The surface of the workpiece is immersed in a hole to complete the sealing of the anode tube (1) (shown in the second figure);

5. Remove the workpiece component after the protective film sealing procedure of the finished surface is dry and solid.

Since the color material (2) is sealed on the anode treated tube anode tube (1), the pattern, characters, symbols and figures distributed by the color material (2) are coated on the surface of the workpiece, in addition to making the whole workpiece more beautiful. In addition, the color material (2) has the high hardness of the anode treatment, so it is not easy to fall off the surface of the workpiece, thereby increasing the life of the product.

The filling of the present invention can be carried out by continuous continuous technology and Drop-on-Demand technology, wherein the Drop-on-Demand can be further divided into: 1. Thermal energy type (Thermal) It can be called Thermal Bubble, Electrostatic, Triple, Piezoelectric, Acoustic, etc. Among them, Piezoelectric can be divided into extrusion. Squeeze Tube, Bend Mode, Push Mode, Shear Mode, etc., output ink into ink drop, ink jet, inkjet effect, and produce very small The ink particles or molecules, the ink particles or molecular size can be from 400 micrometers (Micron; Micrometer) to 1 nanometer (Nanometer), and the fine inks of different colors are respectively filled into more than one anode tube (1) ( Match the inside of the second figure).

In summary, the present invention is considered to comply with the provisions of the Patent Law. The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the equivalent changes and modifications made by the invention in accordance with the scope of the invention are still within the scope of the invention.
