Description

鏡頭檢測裝置 Lens detecting device

本創作係有關於一種鏡頭檢測裝置，尤指一種可降低檢測成本與節省檢測空間之鏡頭檢測裝置。 The present invention relates to a lens detecting device, and more particularly to a lens detecting device capable of reducing the detection cost and saving the detection space.

按，隨著攝像技術之持續發展，鏡頭模組已大量的被使用，其鏡頭模組之應用範圍越來越大，已被廣泛的應用到各攝像裝置中，而攝像裝置也包括相當多的種類，例如數位相機或具照相功能之行動裝置，而鏡頭模組也是各攝像裝置可擷取影像最主要之元件，但鏡頭模組品質之優劣則是直接影像到數位影像之顯示品質，因此，鏡頭模組於出廠前均需經過檢測，以確定製造完成的鏡頭模組符合原設計之規範且保證其出廠良率，而習知鏡頭模組檢測主要是使用以一個光源模組產生光源且由測試圖案件送出，該測試圖案件具有一測試圖案，然後再以複數個感測鏡頭去測試該待測鏡頭模組各位置之光學品質，而複數個感測鏡頭則是需同時設置於一移動平台上，但其測試方式會造成許多問題產生，首先就是其多個感測鏡頭所耗費之檢測成本高，並且其多個感測鏡頭需精準排列於移動平台上，更且若其待測鏡頭為小型之鏡頭時，其係呈現小視角之射出光源，便無法以多個感測鏡頭進行檢測，因其小型之待測鏡頭所透出之測試圖案並無法同時呈現於各感測鏡頭上，若要將其小型待測鏡頭之測試圖案同時呈 現於各感測鏡頭上時，則需要拉長其待測鏡頭與檢測鏡頭間之距離，但在距離加大之情況下，其移動平台所需要之空間與檢測鏡頭數量也相對增加，會有檢測成本與檢測空間提高之問題產生，也因此，習知並沒有針對小型之待測鏡頭進行檢測之檢測裝置。 According to the continuous development of the camera technology, the lens module has been widely used, and the application range of the lens module is getting larger and larger, and has been widely applied to various camera devices, and the camera device also includes quite a lot of Types, such as digital cameras or mobile devices with camera functions, and the lens module is also the most important component for capturing images, but the quality of the lens module is the display quality of direct images to digital images. The lens module must be tested before leaving the factory to determine that the manufactured lens module meets the original design specifications and guarantees its factory yield. The conventional lens module detection mainly uses a light source module to generate the light source. The test pattern member is sent out, the test pattern member has a test pattern, and then the optical quality of each position of the lens module to be tested is tested by using a plurality of sensing lenses, and the plurality of sensing lenses are simultaneously set to be moved. On the platform, but its testing method will cause many problems. The first is that the cost of detecting multiple sensing lenses is high, and its multiple sensing The head needs to be precisely arranged on the mobile platform, and if the lens to be tested is a small lens, the light source that emits a small angle of view can not be detected by multiple sensing lenses, because of the small lens to be tested. The test pattern that is revealed cannot be presented on each sensing lens at the same time, and the test pattern of the small test lens is simultaneously presented. When it is used on each sensing lens, it needs to lengthen the distance between the lens to be tested and the detecting lens. However, when the distance is increased, the space required for the moving platform and the number of detecting lenses are relatively increased. The problem of increased detection cost and detection space arises, and therefore, there is no known detection device for detecting a small lens to be tested.
