九、發明說明： 【發明所屬之技術領域】 本發明係關於一種物件表面之光學檢測裝置，特別是關於 一種利用數個反射鏡形成三組實質等長之影像反射路徑，以便 由單一影像擷取單元擷取待測物件360度表面影像之光學檢 測裝置。 【先前技術】 現今許多產品，例如晶片電容、晶片電阻、IC封裝體、螺 絲、螺帽、水果或其他之電子元件、農產品或手工藝品，其在 生產、製造或採收後通常需要進行一道光學影像之檢測程序， 以便得知產品是否具有表面缺陷及是否符合預定尺寸大小，進 而方便產tm分級包裝、監控產品良率及確保產品出廠時之一致 性等。為了完成上述物件表面之光學檢測程序，相關業者於是 不斷改良研發出各種物件表面之光學檢測裝置。 例如’中華民國公告第5M771號新型專利揭示一種螺絲影 像筛選機構造改良之裝置’其係將二組攝像機置放於筛選機 則，該一組攝像機設置為不同平面，一為擷取定位壓頭機構與

動檢測機，其係在一輸送帶的輸送方向依序設置第_、第二與 第二檢測裝置，螺帽由輸送帶輸送通過該些檢測裝置，利用第 一檢測裝置從上方對螺帽進行檢測，若合格則繼續輸送到第二 檢測裝置，以從上側方對螺帽進行不同項目的檢測，若合格則 繼續被輸送到第三檢測裝置，以從侧邊對螺帽進行其他檢測， 若合格則予以收取。在該光學檢測裝置中，其設置三組檢測裝 置’以拍攝螺帽不同角度之表面影像。 再者，中華民國公告第厘273713號新型專利揭示一種電子 元件之品質檢測裝置，其利用一置料轉盤運送一電子元件(如 晶片電容)依序經過各工作站。數個動態攝影機分別用以擷取 各工作站位置之電子元件的影像，該影像則由電腦分別處理。 若該電腦判別任一工作站之電子元件具有瑕庇時，該工作站即 去除電子元件之不良品。若完成所有工作站之檢測，該電子元 件則判別為良品。在該光學檢測裝置中，其設置六組動態攝影 機，以拍攝電子元件不同角度之表面影像，其中第三及第四組 動態攝影機係在其工作站之上下側分設數個反射鏡，以擷取電 子元件之上下侧影像，但其在電子元件之二端面仍有攝影死 角’無法同時擷取電子元件之360度表面影像。 6 再者，令華民國公告第1239391號發明專利揭示一種影像 輔助全自動甸爾夫球定位及表面商標瑕疵檢測系統，其包含一 〜像操取裝置、—照明裝置、-球定位機構及-影像分析之電 腦整合單元，由於該球定位機構為具X、Y及z轴之旋轉及定 位機構，可適時轉動待測球體，因此該檢測系統可利用單一影 像掏取襄置進行全方位偵測高爾夫球、鋼珠或其他球體之各種 表面瑕疲及品管檢測0 然而，上述各種物件表面之光學檢測裝置實際上仍存在技 術問題’例如··若物件表面之光學制裝置設置數組影像娜 單元，將相對增加機台製造及維修之成本與影像整合的複雜 度。若物件表面之光學檢測裝置設置單组影像擷取單元並搭配 使用一轉動定位機構，則僅適用於檢測圓球狀物件；如果物件 具有明顯的表面凹陷或輪廓呈不規則狀，則轉動中的物件可能 產生不規則的震動或翻轉，導致動態擷取之影像過於複雜或含 有雜訊，因而增加電腦整合單元處理及判斷動態影像的難度。 故，有必要提供一種物件表面之光學檢測裝置，以解決習知技 術所存在的缺陷。 【發明内容】

INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD The present invention relates to an optical detecting device for an object surface, and more particularly to a method for forming three sets of substantially equal-length image reflecting paths by using a plurality of mirrors for capturing from a single image. The unit takes an optical detecting device for capturing a 360-degree surface image of the object to be tested. [Prior Art] Many products today, such as wafer capacitors, chip resistors, IC packages, screws, nuts, fruit or other electronic components, agricultural products or handicrafts, usually require an optical after production, manufacturing or harvesting. The image detection procedure is to know whether the product has surface defects and conforms to the predetermined size, and thus facilitates the production of tm grading packaging, monitoring product yield and ensuring the consistency of the product at the time of shipment. In order to complete the optical inspection process for the surface of the above objects, the related art has continuously improved the optical detecting device for developing various object surfaces. For example, 'The Republic of China Announcement No. 5M771's new patent discloses a device for improving the structure of a screw image screening machine', in which two sets of cameras are placed on a screening machine, the set of cameras are set to different planes, and one is for positioning. The indenter mechanism and the screw head are in contact with the image of the relevant position of the Φ; the other is the image of the position of the screw on the shed and the screw, and the image of the lion is transmitted to the cancer, and the various screws are quickly calculated. Size and specifications. Furthermore, the Republic of China Announcement No. M323343 and the new No. 1114 patent also disclose a similar 5 1377341 optical detection device, which also sets two sets of cameras to capture the surface images of the screws at different angles for the optical surface of the object. Detection. Furthermore, the new patent No. 568198 discloses a nut automatic detecting machine which sequentially sets the first, second and second detecting means in the conveying direction of the conveyor belt, and the nut is conveyed by the conveyor belt. The detecting device uses the first detecting device to detect the nut from above, and if it is qualified, continues to the second detecting device to detect different items from the upper side of the nut, and if it is qualified, continues to be transported to the first The third detection device performs other tests on the nut from the side and collects if it is qualified. In the optical detecting device, three sets of detecting means are provided to photograph surface images of different angles of the nut. Further, the new patent of the Republic of China Publication No. 273,713 discloses a quality detecting device for an electronic component which uses an idler to transport an electronic component (e.g., a chip capacitor) sequentially through each workstation. Several dynamic cameras are used to capture images of the electronic components at the workstation locations, which are processed separately by the computer. If the computer determines that the electronic components of any of the workstations are sheltered, the workstation removes the defective components of the electronic components. If all workstations are tested, the electronic component is judged to be good. In the optical detecting device, six sets of dynamic cameras are arranged to capture surface images of different angles of the electronic components, wherein the third and fourth sets of dynamic cameras are provided with a plurality of mirrors on the lower side of the workstation to capture The lower side of the electronic component, but there are still photographic corners on both ends of the electronic component 'cannot simultaneously capture the 360-degree surface image of the electronic component. 6 Furthermore, the invention patent of the Republic of China Publication No. 1239391 discloses an image-assisted automatic Dingfu ball positioning and surface mark defect detection system, which comprises an image manipulation device, a lighting device, a ball positioning mechanism and The computer integrated unit for image analysis, because the ball positioning mechanism is a rotation and positioning mechanism with X, Y and z axes, can rotate the ball to be tested in time, so the detection system can perform all-round detection by using a single image capturing device Various surface fatigue and quality inspection of golf balls, steel balls or other spheres. However, the optical detection devices on the surface of the above-mentioned various objects actually still have technical problems. For example, if the optical device on the surface of the object is provided with an array of image elements, The complexity of integrating the cost of manufacturing and maintenance of the machine with the image will be relatively increased. If the optical detecting device on the surface of the object is provided with a single image capturing unit and used with a rotating positioning mechanism, it is only suitable for detecting a spherical object; if the object has a significant surface depression or an irregular contour, the rotation is The object may generate irregular vibration or flipping, which may result in the image being dynamically captured being too complicated or containing noise, thus increasing the difficulty of processing and judging the dynamic image by the computer integrated unit. Therefore, it is necessary to provide an optical detecting device for the surface of an object to solve the defects of the prior art.
