Description

可提高曲面噴塗均勻性之噴塗裝置Spraying device capable of improving uniformity of curved surface spraying

本發明係一種可提高曲面噴塗均勻性之噴塗裝置，尤指一種於曲面物體上噴塗二氧化鈦(TiO 2)，可提高均勻性之噴塗裝置。 The invention is a spraying device which can improve the uniformity of spraying on a curved surface, especially a spraying device which sprays titanium dioxide (TiO 2 ) on a curved surface object and can improve the uniformity.

按，手機之曲面蓋板，於製造過程中，待測手機曲面蓋板在使用掃描時，需要以二氧化鈦(TiO 2)覆蓋其表面，以避免機台投射之藍光直接穿透待測物，而不是反射回兩側的鏡頭。 Press the curved cover of the mobile phone. During the manufacturing process, the curved cover of the mobile phone to be tested needs to be covered with titanium dioxide (TiO 2 ) during its scanning to prevent the blue light projected by the machine from directly penetrating the object to be measured. Not reflected back to the lens on both sides.

目前的方式，是透過噴槍將二氧化鈦(TiO 2)附著在待測物表面。雖然噴塗時會保持一段距離，讓霧化後的塗料可以比較均勻的覆蓋，但靠近噴槍口中心的區域，塗料還是較濃的，再加上個人噴塗手法的不同，導致待測物噴塗後的厚度與均勻度有一定程度的差異，也就是說，塗料會集中於噴口中心，若技巧不夠好，甚至會差到50um以上，相當不便利。 The current method is to attach titanium dioxide (TiO 2 ) to the surface of the test object through a spray gun. Although a certain distance will be maintained during spraying so that the atomized paint can be covered more evenly, but the area near the center of the spray gun mouth is thicker. In addition, the difference in personal spraying techniques results in There is a certain degree of difference in thickness and uniformity, that is to say, the paint will be concentrated in the center of the nozzle. If the skill is not good enough, it will even be worse than 50um, which is quite inconvenient.
