整合性振動檢測方法及其裝置 Integrated vibration detecting method and device thereof

本發明係關於一種整合性振動檢測裝置，尤指一種用於檢測鏡頭在振動測試中可即時檢測鏡片是否鬆動而導致光軸偏移之整合性振動檢測裝置。 The present invention relates to an integrated vibration detecting device, and more particularly to an integrated vibration detecting device for detecting whether a lens is instantaneously detected in a vibration test to cause looseness of an optical axis.

一般鏡頭於組裝時皆是將鏡片依序裝入鏡筒中，而在鏡頭組裝時為固定鏡片於鏡筒中之位置，常使用膠水來固定鏡片，但是常因鏡筒設計緣故，因此有時無法用膠水將鏡片牢固在鏡筒上因而導致鏡頭經過振動測試後鏡偏鬆脫而導致光軸偏移。而目前在檢測鏡片鬆動所引起之光軸偏移常須等到整個鏡頭組裝成攝影機之後才能進行檢測無法即時檢測鏡頭光軸是否因振動而產生鬆脫，如此一來當鏡片因組裝鬆動造成光軸偏移偏移會導致攝影機品質不良，導致整組攝影機須報廢，如此一來就形成組裝成本的偏高。 Generally, the lens is assembled into the lens barrel in order, and the lens is fixed in the lens barrel when the lens is assembled. The glue is often used to fix the lens, but often because of the lens tube design, sometimes it is impossible to use The glue secures the lens on the lens barrel, causing the lens to be loosened after the lens has been subjected to the vibration test, resulting in a shift in the optical axis. At present, the optical axis shift caused by detecting the looseness of the lens often has to wait until the entire lens is assembled into a camera before detecting. It is impossible to immediately detect whether the optical axis of the lens is loose due to vibration, so that the optical axis is caused by loose assembly. The offset offset will result in poor quality of the camera, which will cause the entire camera to be scrapped, which will result in higher assembly costs.

鑒於上述知習知之缺失，本發明之發明人提出一種解決上述無法即時檢測因鏡片鬆脫導致光軸偏移之振動檢測裝置，用以改進上述之缺失。 In view of the above-mentioned lack of knowledge, the inventors of the present invention have proposed a vibration detecting device which can not immediately detect the optical axis shift due to loose lens, and to improve the above-mentioned deficiency.

本發明之目的在提出一種整合性振動檢測裝置，該整合性振動檢測裝置包含有一檢測治具，該檢測治具裝設於一振動測試機台上；其中該檢測治具包含有至少一個鏡頭固定模組，該鏡頭固定模組用以裝設待測鏡頭；一檢測圖，該檢測圖至少包含一特徵圖形，該特徵圖形包括一十字標示圖或一解析度圖形；該檢測圖裝設於待測鏡頭一側用以反射穿射過待測鏡頭之光線；一影像成形單元，該影像成形單元裝設於檢測治具上相對於檢測圖之一側，該影像成形單元用以感應經由檢測圖所反射之光線所形成之比對圖形影像，其中該影像成形單元可以是電荷耦合元件(CCD)也可以是互補式金屬氧化物半導體(CMOS)；一檢測機，該檢測機與檢測治具以傳輸線相連結，該檢測機用以檢測經由影像成形單元所形成之影像；一顯示單元，該顯示單元與檢測機以信號傳輸線相連接。 The object of the present invention is to provide an integrated vibration detecting device, comprising: a detecting fixture mounted on a vibration testing machine; wherein the detecting fixture comprises at least one lens fixing a module, the lens fixing module is configured to mount a lens to be tested; and a detection image, the detection image includes at least one feature graphic, the feature graphic includes a cross mark map or a resolution graph; The image forming unit is configured to reflect light passing through the lens to be tested; an image forming unit is disposed on one side of the detecting fixture relative to the detecting image, and the image forming unit is configured to sense the passing through the detecting image a contrast image formed by the reflected light, wherein the image forming unit may be a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS); a detecting machine, the detecting device and the detecting fixture The transmission line is connected to the image, and the detector is configured to detect an image formed by the image forming unit; a display unit, the display unit and the detector are connected by a signal transmission line Access.

將該整合性振動檢測裝置至於工作桌或振動機台上，以手動或振動機台進行振動測試時，外部光線穿過待測鏡頭時，外部光線經由檢測圖反射至影像成形單元，影像成形單元將檢測圖所反射之光線轉換成影像輸出至檢測機，檢測機即時判讀檢測圖所形成之前後影像同時進行比對該前後影像，由該檢測機比對該影像成形單元輸出之不同時序之檢測圖影像，比對前後檢測圖影像之特徵圖形相對座標位置或影像解析度，當該特徵圖形之座標位置差異或解析度圖形之解析度超過所設定之閥值時，則表示鏡片產生鬆脫，此時即發出警示訊號，而檢測機則將振動測試時之影像輸出至顯示螢幕顯示。 When the integrated vibration detecting device is placed on the working table or the vibrating machine table and is subjected to the vibration test by the manual or the vibrating machine, when the external light passes through the lens to be tested, the external light is reflected to the image forming unit through the detecting image, and the image forming unit The light reflected by the detection image is converted into an image output to the detecting machine, and the detecting machine immediately interprets the image formed before and after the detection image is simultaneously compared with the front and rear images, and the detecting device compares the different timings of the output of the image forming unit. Image, comparing the coordinate position of the feature image relative to the coordinate position or the image resolution before and after the image, when the coordinate position difference of the feature graphic or the resolution of the resolution graphic exceeds the set valve When the value is displayed, it indicates that the lens is loose, and then a warning signal is issued, and the detector outputs the image during the vibration test to the display screen.

由上述得知當鏡片因鬆動導致光軸偏移時，藉由檢測比對圖形之座標位置或解析度變化可即時得知光軸是否因鏡片鬆動而產生偏移，如此可以在尚未組裝成攝影機時可即時將不良品汰除，以減輕成本。 It can be known from the above that when the lens is displaced due to looseness, by detecting the coordinate position or resolution change of the comparison pattern, it is immediately known whether the optical axis is offset due to loose lens, so that it can be assembled into a camera. The defective products can be eliminated immediately to reduce costs.
