鍍膜裝置Coating device

本發明涉及鍍膜領域，特別是一種採用蒸鍍方式的鍍膜裝置。The invention relates to the field of coating, in particular to a coating device using an evaporation method.

在某些光學鏡頭模組內，我們需要在鏡片的側壁鍍上一層薄膜以避免被鏡頭模組內其他材料所腐蝕。In some optical lens modules, we need to apply a thin film on the sidewall of the lens to avoid corrosion by other materials in the lens module.

如圖1和圖2所示，其分別為鏡片10的側面視圖和俯視圖。一般鍍膜多半是鍍在鏡片10的入光面和出光面，蒸鍍裝置內的機構也是依此而設計，但是，有些保護膜所要鍍的部份是鏡片10的側壁104，這就是的現有的鍍膜機構無法完成，而且，鍍膜過程都是複數鏡片10的同時蒸鍍。因此，如何實現鏡片10的側壁104上鍍膜成為了業界需要解決的問題。1 and 2, which are respectively a side view and a top view of the lens 10. Generally, most of the coating is plated on the light incident surface and the light exit surface of the lens 10. The mechanism in the vapor deposition device is also designed accordingly. However, some of the protective film is to be plated on the side wall 104 of the lens 10, which is the existing one. The coating mechanism cannot be completed, and the coating process is simultaneous vapor deposition of the plurality of lenses 10. Therefore, how to realize the coating on the side wall 104 of the lens 10 has become a problem to be solved in the industry.
