The support frame 2 can include a base 21 and a support rod 22. The support rod 22 is erected on the base 21, and the jig 23 is inserted at the end of the support rod 22 to fix the housing 1 to the support frame 2 by the jig 23 and the support rod 22. In addition, the plurality of support frames 2 can be disposed on a conveyor belt (not shown) to allow the casing 1 mounted on the support frame 2 to be sprayed on the production line relative to the first spray gun by the conveyor belt. The system moves. Furthermore, as shown in FIG. 1C, the two first spray guns N1 are respectively fixed with their spraying angles, and can be rotated by a rotating unit (not shown, for example, including a motor, a belt, a transmission rod, etc.) to The casing 1 can be rotated relative to the first lance system so that the paint sprayed by the two first lances N1 can be uniformly applied to the surface of the casing 1. Of course, in other embodiments, the user can also move or rotate the relative position and spray angle between the first spray gun N1 and the housing 1. In the present embodiment, only one housing 1 is shown, and the first spray gun system has two first spray guns N1 with a fixed spray angle. Of course, it is not limited thereto, and different numbers of housings 1 and different The number of first lances N1 (e.g., six first lances N1 are provided) sprays the first coating onto the housing 1 at different or the same angle.
如圖1C所示，殼體1具有一表面11，而表面11可具有一背面111及一側面112。於此，背面111係為殼體1之一頂面，而側面112係位於背面111之側邊。其中，背面111與側面112係可形成一角度θ 1，而角度θ 1可介於 0度至120度之間。於此，係以90度為例。 As shown in FIG. 1C, the housing 1 has a surface 11 and the surface 11 can have a back surface 111 and a side surface 112. Here, the back surface 111 is a top surface of the casing 1 and the side surface 112 is located on the side of the back surface 111. Wherein, the back surface 111 and the side surface 112 can form an angle θ 1, and the angle θ 1 can be between Between 0 and 120 degrees. Here, the example is 90 degrees.
請分別參照圖1C、圖2及圖3所示，其中，圖2為本發明較佳實施例之一種殼體噴塗方法的流程示意圖，而圖3為本發明之一第二噴槍系統噴塗殼體1之側面112時的示意圖。於此，圖3仍顯示一個殼體1及其對應的支持架2，並顯示一第二噴槍N2。當然，實際應用時，第二噴槍系統可具有複數第二噴槍N2。 Referring to FIG. 1C, FIG. 2 and FIG. 3 respectively, FIG. 2 is a schematic flow chart of a method for spraying a casing according to a preferred embodiment of the present invention, and FIG. 3 is a spray casing of a second spray gun system of the present invention. Schematic diagram of the side 112 of 1 . Here, FIG. 3 still shows a housing 1 and its corresponding support frame 2, and shows a second spray gun N2. Of course, in practical applications, the second spray gun system can have a plurality of second spray guns N2.
本發明之殼體噴塗方法可包括步驟S01及步驟S02。 The housing spraying method of the present invention may include step S01 and step S02.
步驟S01：如圖1C所示，利用一第一噴槍系統噴塗一第一塗料於至少背面111。於此，係以兩第一噴槍N1至少於背面111上噴塗第一塗料。其中，第一噴槍N1的主要噴塗方向與背面111平面的延伸方向P具有一夾角θ 2，且夾角θ 2係可介於30度至120度之間。 Step S01: As shown in FIG. 1C, a first paint system is applied to at least the back surface 111 by a first spray gun system. Here, the first paint is sprayed on at least the back surface 111 by the two first spray guns N1. Wherein, the main spraying direction of the first spray gun N1 has an angle θ 2 with the extending direction P of the back surface 111 plane, and the angle θ 2 may be between 30 degrees and 120 degrees.
另外，步驟S02：如圖3所示，利用一第二噴槍系統噴塗一第二塗料於側面112。於此，第二噴槍系統具有一支第二噴槍N2，且其主要噴塗方向與背面111的延伸方向P具有一夾角θ 3，且夾角θ 3係介於10度至80度之間。 In addition, step S02: as shown in FIG. 3, a second coating is applied to the side surface 112 by a second spray gun system. Here, the second spray gun system has a second spray gun N2, and its main spray direction has an angle θ 3 with the extending direction P of the back surface 111, and the included angle θ 3 is between 10 degrees and 80 degrees.
上述之主要噴塗方向係指第一噴槍N1或第二噴槍N2之最大射出量的方向，也是第一噴槍N1或第二噴槍N2之噴出點與殼體1之表面11的被噴塗點的連線方向，故夾角θ 2、θ 3係分別為第一噴槍N1及第二噴槍N2之軸線方向或長軸方向與延伸方向P之間的夾角。在本實施例中，第一噴槍N1的數量為二支，而第二噴槍N2的數量為一支，且兩第一噴槍N1的主要噴塗方向與方向P之夾角 θ 2分別為40度及90度，而第二噴槍N2的主要噴塗方向與方向P之夾角θ 3為35度為例。其中，第一噴槍N1及第二噴槍N2噴塗時係可分別固定其與方向P之夾角θ 2、θ 3，並可一邊噴塗一邊平行移動第一噴槍N1或第二噴槍N2，且底座21也可同時旋轉，再者，可藉由控制第一噴槍N1及第二噴槍N2的氣體壓力來控制第一塗料的噴出量，使第一塗料及第二塗料可均勻地塗佈於表面11上。再一提的是，在其它的實施例中，也可分別設置不同數量的第一噴槍N1及第二噴槍N2，並同時噴塗第一塗料及第二塗料。 The above-mentioned main spraying direction refers to the direction of the maximum injection amount of the first spray gun N1 or the second spray gun N2, and is also the connection line between the discharge point of the first spray gun N1 or the second spray gun N2 and the painted point of the surface 11 of the casing 1. The direction, so the angles θ 2, θ 3 are the angles between the axial direction of the first lance N1 and the second lance N2 or the direction of the major axis and the direction of extension P, respectively. In this embodiment, the number of the first spray guns N1 is two, and the number of the second spray guns N2 is one, and the angle between the main spraying direction of the two first spray guns N1 and the direction P is θ 2 is 40 degrees and 90 degrees, respectively, and the angle θ 3 between the main spraying direction of the second spray gun N2 and the direction P is 35 degrees. Wherein, when the first spray gun N1 and the second spray gun N2 are sprayed, the angles θ 2 and θ 3 between the first spray gun N1 and the second spray gun N2 can be respectively fixed, and the first spray gun N1 or the second spray gun N2 can be moved in parallel while spraying, and the base 21 is also The first coating material and the second coating material can be uniformly applied to the surface 11 by controlling the gas pressure of the first spray gun N1 and the second spray gun N2 to control the discharge amount of the first paint. In addition, in other embodiments, different numbers of the first spray gun N1 and the second spray gun N2 may be separately disposed, and the first paint and the second paint may be sprayed at the same time.
第一塗料與第二塗料例如可為紫外光固化油漆(UV漆)、合成樹脂漆、環氧樹脂漆或其它塗料，並可具有相同顏色或不相同顏色，也可具有相同或不相同的光澤度。在本實施例中，如圖4所示，第一塗料與第二塗料係分別為透明的UV漆，且具有不同光澤度為例。其中，殼體1之背面111上噴塗的第一塗料之光澤度係小於側面112噴塗的第二塗料之光澤度，且第一塗料與第二塗料的交接處實質上係形成一相當平整且明顯的界限，而此界限係實質為一直線，且此直線也與背面111及側面112之間的稜線重疊(所謂稜線即為兩不同曲面之間的交界線)。於此，第一塗料的光澤度係接近0度，而第二塗料的光澤度係接近100度。當然，在其它的實施態樣中，第一塗料與第二塗料也可具有不同的顏色但具有相同的光澤度或不同的光澤度，使殼體1成為一雙色或一雙光澤度的機殼。其中， 光澤度係以光澤度計(gloss Meter)來量測物體表面，並用以評估物體表面是否光滑的視覺現象，從物體表面上反射的光線越多，則光澤度越高。因此，第一塗料的光澤度接近0度是代表為全霧狀而較無法反射光線，而第二塗料的光澤度接近100度代表為全亮狀而較能將光線反射。 The first coating and the second coating may be, for example, ultraviolet curable paint (UV paint), synthetic resin paint, epoxy paint or other paint, and may have the same color or different colors, or may have the same or different gloss. degree. In this embodiment, as shown in FIG. 4, the first paint and the second paint are respectively transparent UV paints, and have different glosses as an example. Wherein, the gloss of the first coating sprayed on the back surface 111 of the casing 1 is less than the gloss of the second coating sprayed by the side surface 112, and the intersection of the first coating material and the second coating material is substantially flat and distinct. The boundary is substantially a straight line, and the line also overlaps the ridge line between the back surface 111 and the side surface 112 (the so-called ridge line is the boundary line between the two different curved surfaces). Here, the gloss of the first coating is close to 0 degrees, and the gloss of the second coating is close to 100 degrees. Of course, in other embodiments, the first coating and the second coating may also have different colors but have the same gloss or different gloss, so that the casing 1 becomes a two-color or a double-gloss case. . among them, Gloss is a glossometer that measures the surface of an object and is used to evaluate whether the surface of the object is smooth or not. The more light that is reflected from the surface of the object, the higher the gloss. Therefore, the gloss of the first coating is close to 0 degrees, which means that it is completely foggy and less reflective, while the gloss of the second coating is close to 100 degrees, which means that it is fully bright and more reflective.
另外，在實際製程中，也可於噴塗第一塗料及第二塗料之前先噴塗一底漆於背面111及側面112上，可使殼體1具有底色，並例如具有耐水性、防蝕性或附著性等等性能。其中，底漆可與第一塗料或第二塗料具有相同或不同的顏色及光澤度。當第一塗料的光澤度很小時，也可將第一塗料當成殼體1之底漆使用，並於步驟S01時將第一塗料一併噴塗於殼體1之背面111及側面112上，以將第一塗料當成殼體1的底漆來使用(可省略底漆的噴塗)。 In addition, in the actual process, a primer may be sprayed on the back surface 111 and the side surface 112 before spraying the first coating material and the second coating material, so that the housing 1 has a ground color and is, for example, water resistant, corrosion resistant or Adhesion and other properties. Wherein, the primer may have the same or different color and gloss as the first coating or the second coating. When the gloss of the first coating is small, the first coating may be used as the primer of the casing 1, and the first coating is sprayed on the back surface 111 and the side surface 112 of the casing 1 in step S01. The first coating is used as a primer for the casing 1 (the spraying of the primer can be omitted).
另外，請參照圖5A及圖5B所示，其中，圖5A為本發明較佳實施例之另一種殼體噴塗方法的流程示意圖，而圖5B為本發明另一殼體3噴塗時的示意圖。於此，圖5B只顯示一個殼體3及其對應的支持架2。 5A and FIG. 5B, FIG. 5A is a schematic flow chart of another method for spraying a casing according to a preferred embodiment of the present invention, and FIG. 5B is a schematic view of another casing 3 according to the present invention. Here, FIG. 5B shows only one housing 3 and its corresponding support frame 2.
除了上述將第一噴塗系統及第二噴塗系統同時噴塗第一塗料及第二塗料於殼體的步驟S01及步驟S02之外，殼體噴塗方法更可包括步驟S03：如圖5B所示，遮蓋殼體3之背面311及側面312，並噴塗一第三塗料於殼體3之一正面32上。其中，正面32係與側面312連接，使殼體3具有一倒勾，而第三塗料可與第一塗料或第二塗料具有相同或不同顏色，或具有相同或不相同的光澤度。於此， 殼體3仍以電子裝置之機殼(背蓋)為例。不過，也可將殼體3當成電子裝置之保護蓋來使用，以將電子裝置安裝於保護蓋內，以保護電子裝置免於被異物刮傷。另外，係可藉由一遮罩或一模具M覆蓋背面311與側面312，使得第三噴槍N3噴塗第三塗料於正面32時不會噴塗至背面311與側面312。在本實施例中，第三塗料係與第一塗料具有相同顏色及相同光澤度(霧狀)為例，使得第一塗料、第二塗度及第三塗料分別為霧狀、亮狀及霧狀。 In addition to the step S01 and the step S02 of spraying the first coating and the second coating on the casing in the first spraying system and the second spraying system, the shell spraying method may further comprise the step S03: as shown in FIG. 5B, covering The back surface 311 and the side surface 312 of the casing 3 are sprayed with a third coating material on one of the front faces 32 of the casing 3. Wherein, the front side 32 is connected to the side surface 312 such that the housing 3 has a barb, and the third coating may have the same or different color as the first coating or the second coating, or have the same or different gloss. herein, The housing 3 is still exemplified by a casing (back cover) of an electronic device. However, the housing 3 can also be used as a protective cover for an electronic device to mount the electronic device in the protective cover to protect the electronic device from being scratched by foreign objects. In addition, the back surface 311 and the side surface 312 can be covered by a mask or a mold M, so that the third spray gun N3 sprays the third paint on the front surface 32 without spraying to the back surface 311 and the side surface 312. In this embodiment, the third paint system and the first paint have the same color and the same gloss (fog shape) as an example, so that the first paint, the second paint, and the third paint are respectively foggy, bright, and fogged. shape.
此外，殼體噴塗方法更可包括步驟S04：利用熱風型烤箱、密閉型烤箱或紫外線照射，以固化殼體3上的塗料。於此，係藉由烘烤的方式使殼體3上之塗料固化，以完成殼體3的噴塗工作。 Further, the housing spraying method may further include the step S04 of irradiating the coating on the casing 3 with a hot air type oven, a closed type oven or ultraviolet rays. Here, the coating on the casing 3 is solidified by baking to complete the spraying operation of the casing 3.

另外，殼體噴塗方法更可包括步驟P03：如圖6B所示，利用一第三噴槍系統噴塗一第三塗料於殼體4之一正面411上。其中，步驟P03與步驟S03不同，並不使用遮罩或模具覆蓋背面411與側面412，而是藉由直接控制第三噴槍系統之一第三噴嘴N3來控制第三塗料噴塗於殼體4之正面42上，一樣可使噴塗第三塗料於正面42時不會噴塗至背面411與側面412。 In addition, the housing spraying method may further include step P03: spraying a third coating on the front surface 411 of the housing 4 by using a third spray gun system as shown in FIG. 6B. Wherein, step P03 is different from step S03, and the back surface 411 and the side surface 412 are not covered by using a mask or a mold, but the third paint is sprayed on the casing 4 by directly controlling one of the third nozzles N3 of the third spray gun system. On the front side 42, the third coating can be sprayed onto the front side 42 without being sprayed onto the back side 411 and the side surface 412.
此外，殼體噴塗方法更可包括步驟P04：利用熱風型烤箱、密閉型烤箱或紫外線照射，以固化殼體4，以完成殼體4的噴塗工作。 In addition, the housing spraying method may further include step P04: using a hot air type oven, a closed type oven or ultraviolet light to cure the housing 4 to complete the spraying operation of the housing 4.
綜上所述，因本發明之殼體噴塗方法係利用第一噴槍系統噴塗第一塗料於至少殼體之背面上，再利用第二噴槍系統噴塗第二塗料於殼體之側面上，且第二噴槍系統的主要噴塗方向與背面的延伸方向具有一夾角，該夾角係介於10度至80度之間。藉此，可不用遮罩或模具就可噴塗至少兩種塗料於殼體上，並使兩種塗料的交接處相當平整。因此，不僅可提昇產品的美觀性及減少製程的成本，更可提升產品的競爭力。 In summary, the shell spraying method of the present invention uses the first spray gun system to spray the first paint on at least the back surface of the casing, and then sprays the second paint on the side of the casing by using the second spray gun system, and The main spray direction of the two spray gun system has an angle with the extension direction of the back side, and the angle is between 10 degrees and 80 degrees. Thereby, at least two kinds of paint can be sprayed on the casing without using a mask or a mold, and the intersection of the two paints is relatively flat. Therefore, not only can the aesthetics of the product be improved, the cost of the process can be reduced, and the competitiveness of the product can be improved.
