Description
本發明是有關於一種表面處理方法，特別是一種漸層陽極表面處理方法。 The present invention relates to a surface treatment method, and more particularly to a gradient anode surface treatment method.
對於電腦、通訊、手機等等的電子產品而言，除了本身機能上的提升之外，消費者開始注重於電子產品的外觀。換言之，若是僅提升電子產品的機能，已經不足以吸引消費者購買。 For electronic products such as computers, communications, mobile phones, etc., in addition to the improvement in their own functions, consumers began to pay attention to the appearance of electronic products. In other words, if it only enhances the functions of electronic products, it is not enough to attract consumers to buy.
舉例來說，開始有許多前述的電子產品開始在產品表面進行各種裝飾，有的是利用額外的裝飾品鑲嵌，或是在表面貼上具黏附性的裝飾品，亦有人在產品表面處理出各種顏色，藉此吸引消費者購買。 For example, many of the aforementioned electronic products began to be decorated on the surface of the product, either by using additional decorations or by attaching adhesive decorations to the surface, and some people have processed various colors on the surface of the product. In order to attract consumers to buy.
然而，一般利用陽極處理想使產品表面具有漸層顏色效果時，因一次只能處理一層並需慢慢拉昇來達成漸層效果，因此具有只有單一方向漸層顏色及產能過低的缺點。 However, when the anode treatment is generally used to have a gradual color effect on the surface of the product, since only one layer can be processed at a time and it is necessary to slowly pull up to achieve a gradation effect, there is a disadvantage that only a single direction gradation color and a low productivity are produced.
有鑑於此，本發明之目的就是在提供一種漸層陽極表面處理方法，以解決漸層處理只有單一方向漸層顏色及產能過低的缺點。 In view of the above, the object of the present invention is to provide a method for surface treatment of a gradient anode to solve the disadvantage that the gradation treatment has only a single direction of gradation color and low productivity.
緣是，為達上述目的，依本發明之漸層陽極表面處理方法，包含 下列步驟：提供工件以及非導電仿型治具，其中，工件具有開放部以及該非導電仿型治具遮蔽之遮蔽部，工件與非導電仿型治具之間隙例如具有0.2至0.5公分之間距以產生所述之遮蔽部。換言之，遮蔽部會使陽極處理時所產生的陽極氧化膜之厚度較小，而染色的深淺又與陽極氧化膜之厚度有正相關，因此漸層處理的顏色就可以依據遮蔽部的區域有多種方向產生。 The edge is that, in order to achieve the above object, the method for surface treatment of a gradient anode according to the present invention comprises The following steps are: providing a workpiece and a non-conductive profile fixture, wherein the workpiece has an open portion and a shielding portion of the non-conductive pattern fixture, and the gap between the workpiece and the non-conductive pattern fixture is, for example, between 0.2 and 0.5 cm. The shielding portion is produced. In other words, the shielding portion causes the thickness of the anodized film generated during the anodizing process to be small, and the depth of the dyeing is positively correlated with the thickness of the anodized film, so that the color of the gradient processing can be various depending on the area of the shielding portion. The direction is generated.
接著，對工件該非導電仿型治具進行陽極處理以產生陽極氧化膜，其中遮蔽部之陽極氧化膜之厚度係小於開放部之陽極氧化膜。 Next, the non-conductive pattern jig of the workpiece is anodized to produce an anodized film, wherein the thickness of the anodized film of the shielding portion is smaller than the anodized film of the open portion.
然後對工件進行染色處理，藉以使工件之表面依據陽極氧化膜之厚度產生漸層顏色。其中，陽極處理係例如在攝氏15至25度進行，持續時間係15至30分，而染色處理係例如在攝氏25至35度進行，持續時間係1至5分。 The workpiece is then dyed so that the surface of the workpiece produces a gradual color depending on the thickness of the anodized film. The anode treatment is carried out, for example, at 15 to 25 degrees Celsius for a duration of 15 to 30 minutes, and the dyeing treatment is carried out, for example, at 25 to 35 degrees Celsius for a duration of 1 to 5 minutes.
此外，在提供工件以及非導電仿型治具之步驟及對工件及非導電仿型治具進行陽極處理之步驟之間，可以進行前處理步驟。例如在攝氏50至70度進行熱浸脫脂2至10分鐘、進行鹼蝕之步驟10至300秒、進行除膜之步驟5至120秒或在攝氏85至105度進行化學拋光10至300秒。 In addition, a pre-processing step can be performed between the steps of providing the workpiece and the non-conductive dummy jig and the step of anodizing the workpiece and the non-conductive profiling jig. For example, hot dip degreasing at 50 to 70 degrees Celsius for 2 to 10 minutes, alkali etching for 10 to 300 seconds, film removal step 5 to 120 seconds, or chemical polishing at 85 to 105 degrees Celsius for 10 to 300 seconds.
承上所述，依本發明之漸層陽極表面處理方法，其可具下述優點：本發明之漸層陽極表面處理方法係透過非導電仿型治具在工件上形成遮蔽部，藉以使開放部與遮蔽部所產生的陽極氧化膜之厚度不同，來解決只能染出單一方向漸層顏色及產能過低的缺點。 According to the above aspect, the method of the gradual anode surface treatment of the present invention has the following advantages: the gradual anode surface treatment method of the present invention forms a shielding portion on the workpiece through the non-conductive patterning fixture, thereby opening The difference between the thickness of the anodized film produced by the portion and the shielding portion is to solve the disadvantage that only a single direction of gradation color and a low productivity are produced.

For ease of understanding, the same elements in the following embodiments are denoted by the same reference numerals.
請參閱第1圖，第1圖係為本發明之漸層陽極表面處理方法之流程圖。第1圖中，本發明之漸層陽極表面處理方法，包含下列步驟。步驟200係提供工件及非導電仿型治具，工件具有開放部以及被非導電仿型治具遮蔽之遮蔽部。具體來說，若是想要在工件上染出較淺的顏色，就可以利用非導電仿型治具遮蔽以使工件上產生遮蔽部。其中，工件與非導電仿型治具之間隙例如具有0.2至0.5公分之間距以形成此遮蔽部，而遮蔽部之效果在於，因為非導電仿型治具係非導體，因此進行步驟210，亦即對工件及非導電仿型治具進行陽極處理以產生陽極氧化膜之步驟時，其中遮蔽部之陽極氧化膜會因為受到非導電仿型治具遮蔽的影響與陰極距離相對較遠，使得電流不易到達。由此可見，遮蔽部之陽極氧化膜之厚度將會小於開放部之陽極氧化膜，這邊要特別提到的是， 開放部係工件未受到非導電仿型治具遮蔽的區域，因此陽極處理時的電流就不會受到非導電仿型治具的影響而使得陽極氧化膜之厚度變薄。 Please refer to FIG. 1 , which is a flow chart of a method for treating a gradient anode surface according to the present invention. In Fig. 1, the method for treating a gradient anode surface of the present invention comprises the following steps. Step 200 provides a workpiece and a non-conductive profile fixture having an open portion and a shield portion that is shielded by a non-conductive replica fixture. Specifically, if it is desired to dye a lighter color on the workpiece, the non-conductive replica can be shielded to create a shadow on the workpiece. Wherein, the gap between the workpiece and the non-conductive pattern jig has a distance of 0.2 to 0.5 cm, for example, to form the shielding portion, and the shielding portion has the effect that since the non-conductive patterning fixture is non-conductor, step 210 is also performed. That is, when the workpiece and the non-conductive dummy fixture are anodized to produce an anodized film, the anodized film of the shielding portion is relatively far away from the cathode due to the shielding by the non-conductive replica fixture, so that the current Not easy to reach. It can be seen that the thickness of the anodized film of the shielding portion will be smaller than that of the anodized film of the open portion, and it is particularly mentioned here that Since the open part is not covered by the non-conductive copying jig, the current during the anodizing process is not affected by the non-conductive copying tool, and the thickness of the anodized film is made thin.
續言之，當工件已經藉由陽極處理在表面形成陽極氧化膜之後，接著可以進行步驟220，也就是對工件進行染色處理，藉以使該工件之表面依據陽極氧化膜之厚度產生漸層顏色。詳言之，工件進行染色處理時，其顏色的深淺將依據工件表面陽極氧化膜之厚度呈正相關之關係，簡單而言，當陽極氧化膜之厚度較大時，其可吸附染料之用量較多，因此會呈現較深的顏色，反之，若陽極氧化膜之厚度較小時，其可吸附染料之用量較少，因此會呈現較淺的顏色。因此，在進行步驟210所產生的陽極氧化膜，其厚度的不同就已經決定了在步驟220染色處理時的顏色深淺。由此可見，本發明之漸層陽極表面處理方法不僅僅只可以用於單一方向之漸層顏色效果，亦可以透過遮蔽部的不同，藉以產生不同方向之漸層效果。 Continuingly, after the workpiece has been anodized to form an anodized film on the surface, step 220 may be performed, that is, the workpiece is subjected to a dyeing treatment, whereby the surface of the workpiece is subjected to a gradation color depending on the thickness of the anodized film. In detail, when the workpiece is dyed, the color depth will be positively correlated according to the thickness of the anodized film on the surface of the workpiece. In simple terms, when the thickness of the anodized film is large, the amount of dye that can be adsorbed is more. Therefore, a darker color is exhibited. Conversely, if the thickness of the anodized film is small, the amount of the adsorbable dye is small, and thus a lighter color is exhibited. Therefore, the difference in thickness of the anodized film produced in the step 210 has already determined the color depth at the time of the dyeing process in the step 220. It can be seen that the gradual anode surface treatment method of the present invention can be used not only for the gradual color effect in a single direction, but also through the difference of the shielding portions, thereby generating a gradation effect in different directions.
另外，吾人更提出本發明之漸層陽極表面處理方法之另一實施方式，請參閱下列流程： In addition, we further propose another embodiment of the gradient anode surface treatment method of the present invention, please refer to the following process:

換言之，在工件在上治具遮蔽以及進行陽極處理之步驟之間，還可以進行前處理步驟205。其中，前處理步驟205可以包含熱浸脫脂、鹼蝕、除膜或化學拋光等等的步驟。藉此提高產品之外觀質 感及良率。 In other words, a pre-processing step 205 can also be performed between the steps of the workpiece being shielded and the anode being processed. Wherein, the pre-treatment step 205 may comprise the steps of hot dip degreasing, alkali etching, film removal or chemical polishing, and the like. Thereby improving the appearance of the product Feeling and yield.
另外，請一併參閱第2至4圖，第2圖係為工件與非導電仿型治具遮蔽時之第一示意圖、第3圖係為工件與非導電仿型治具遮蔽時之第二示意圖以及第4圖係為工件被非導電仿型治具遮蔽時之第三示意圖，其中，距離a係代表工件未被非導電仿型治具遮蔽之距離，此距離可以是1~2公分。在第2至4圖中，工件400與非導體仿型治具300在進行陽極處理時，可以藉由改變工件400與非導電仿型治具300之相對關係以達到各種不同遮蔽部410、411、412以及開放部420、421、422之效果。舉例而言，工件400與非導體仿型治具300係依序依照第2-4圖中工件與非導體仿型治具之狀態進行陽極處理，由於開放部420、421、422係屬於工件400的外露端緣部分，因此，若是將此工件400做染色處理，工件400外露端緣的顏色將會較深，而遮蔽部410、411、412屬於工件400的內側，因此染色處理後工件400的內側顏色會較淺。因此，本發明之漸層陽極表面處理方法確實可以達到在使工件400在不同方向具有漸層效果之優點。此外，這邊要特別提到的是，非導體仿型治具300在工件400所形成的遮蔽部410、411、412會有形成不同厚度的陽極氧化膜(未繪示)之關係，舉例而言，第2圖的陽極氧化膜(未繪示)會形成由右至左是由薄至厚的關係、第3圖的陽極氧化膜(未繪示)會形成由下至上是由薄至厚的關係以及第4圖的陽極氧化膜(未繪示)會形成由左至右是由薄至厚的關係。另外，非導體仿型治具300亦可透過相對工件400轉動一個角度來達成不同遮蔽部之效果。 In addition, please refer to Figures 2 to 4 together. Figure 2 is the first schematic diagram when the workpiece and the non-conductive replica fixture are shielded, and Figure 3 is the second mask when the workpiece and the non-conductive replica fixture are shielded. The schematic view and the fourth figure are the third schematic diagrams when the workpiece is shielded by the non-conductive replica fixture, wherein the distance a represents the distance that the workpiece is not shielded by the non-conductive replica fixture, and the distance may be 1 to 2 cm. In FIGS. 2 to 4, when the workpiece 400 and the non-conductor profiling jig 300 are subjected to anodizing, the relative relationship between the workpiece 400 and the non-conductive profiling jig 300 can be changed to achieve various shielding portions 410, 411. 412 and the effects of the open parts 420, 421, and 422. For example, the workpiece 400 and the non-conductor profiling fixture 300 are anodized in sequence according to the state of the workpiece and non-conductor profiling fixtures in FIGS. 2-4, since the open portions 420, 421, and 422 belong to the workpiece 400. Exposed edge portion, therefore, if the workpiece 400 is dyed, the exposed edge of the workpiece 400 will be darker, and the shielding portions 410, 411, 412 belong to the inner side of the workpiece 400, so the workpiece 400 after the dyeing process The inner color will be lighter. Therefore, the progressive anode surface treatment method of the present invention can indeed achieve the advantage of having the workpiece 400 have a gradation effect in different directions. In addition, it should be particularly mentioned here that the non-conductor profiling fixture 300 has a relationship of forming an anodized film (not shown) of different thicknesses in the shielding portions 410, 411, and 412 formed by the workpiece 400, for example. In other words, the anodized film (not shown) of FIG. 2 is formed from right to left in a thin to thick relationship, and the anodized film (not shown) in FIG. 3 is formed from bottom to top from thin to thick. The relationship and the anodized film (not shown) of Fig. 4 are formed from left to right in a thin to thick relationship. In addition, the non-conductor profiling fixture 300 can also achieve the effect of different shielding portions by rotating an angle with respect to the workpiece 400.
總言之，本發明之漸層陽極表面處理方法係透過陽極氧化膜之厚 度不同，藉此達成工件在染色時就可以有不同方向的漸層顏色。其中，達成陽極氧化膜之厚度不同係利用非導電仿型治具在工件上形成遮蔽部，使得陽極處理時電流不易到達，因此遮蔽部會形成較薄的陽極氧化膜，而開放部就會形成較厚的陽極氧化膜。而染色處理時，工件的顏色深淺又跟陽極氧化膜之厚薄有正相關，因此，本發明之漸層陽極表面處理方法可以達成工件在染色時就可以有不同方向的漸層顏色之功效。 In summary, the gradient anode surface treatment method of the present invention is thick through the anodized film. Different degrees, to achieve the gradient color of the workpiece in different directions when dyeing. Wherein, the thickness of the anodized film is different, and the shielding portion is formed on the workpiece by the non-conductive patterning jig, so that the current is not easily reached during the anode treatment, so that the shielding portion forms a thin anodized film, and the open portion is formed. Thicker anodized film. In the dyeing process, the color depth of the workpiece is positively correlated with the thickness of the anodized film. Therefore, the method of the progressive anode surface treatment of the present invention can achieve the effect of the progressive color of the workpiece in different directions when dyeing.
