201033601 六、發明說明： 【發明所屬之技術領域】 本發明係關於—種視覺檢測設備，尤其係種能夠檢測 裝載於托盤之中的電子元件之外觀的視覺檢測設備。 【先前技術】 電子元件，例如半導體封裝在製造過程中或被投入市場以 前，將經過如電職及外·試等各種不_職，藉以提高成 品率並增加產品的可靠性。 例如，料體封裝可透_晶圓上的製造製程、切割製程及 封裝製程等多個製程加以製造。如果不理會半導體裝置中的缺陷 而後續製程仍被非必要地加以執行，則會使整個製造成本增大。 為了避免這-問題，上述測試係於主要製程之前進行藉以選擇合 格的電子元件。織’這些選出的合格的電子元件練歷後續製 程。 大多數的電子元件在被投入到市場中之前都要經過每一種測 〇 試。因此，僅有合格的電子元件才能出現在市場上，進而提高了 產品的可靠性。 視覺檢測設備用以當其上裝載有電子元件之托盤沿著一導軌。 上下移動時執行視覺檢測，並且一攝像機可沿向右及向左之方向 移動藉以檢測裝載於托盤中的電子元件。由於檢測係於裝載有電 子元件之托盤被傳送時進行，因此裝載於托盤中的電子元件之位 201033601 置會由於托盤之容納槽内的電子元件之間的公差而發生變化。因 此，當測量電子元件之位置時會產生缺陷。下面將更加詳細地對 此進行說明。 第1圖」為習知技術的視覺檢測設備之一實例之平面圖。 如第1圖」所示，習知的用以檢測電子元件之外觀的視覺 檢測設備包含：絲裝鮮元1 ,制以沿著導執la裝載其上裝 載有電子轉之托盤5 ;攝像機2，侧以對已被拾取n 6傳送之 電子元件進行概制；拾取！I 7，制以傳送電子元件藉以將完 全經過視覺檢測之電子元件進行分類；托盤傳送裝置（附圖中未 示出）’係用以傳送托盤5 ;分類單元4，係用以沿著導軌如自動 地傳送托盤5。 然而，習知的視覺檢測設備必須配設有用以自動傳送托盤之 托盤傳送裝置，並且托盤裝載單元丨及分類單元4必須分別配設 φ 有導軌la&4a。同時’在視覺檢測之後必須額外地配設分類裝置， 例如包含有額外的拾取II 7之分鮮元4。如此會導致整體結構過 於複雜’並且會使製造成本過於高昂。 在大批量生產電子元件之情況下，可以採用習知的視覺檢測 ;設備。然而，當昂貴的視覺檢測設備被用於生產少量的電子元件 '之時’整體的製造成本會增大進而會降低生產率。 此外，習知的視覺檢測設備會由於其複雜的結構及較大的尺 寸而佔據相對較大的安裝空間。 5 201033601 為了提岗電子元件之製程的可靠性，視覺檢測設備係安裝於 淨化室中，在淨化室中，可最大化地清除灰塵等物質。如果視覺 檢測設備的尺寸增大，那麼其在淨化室内所佔據的面積也會增 大。如此會降低單位面積上的電子元件之生產量。 習知的視覺檢測設備係透過獲取裝載於托盤5中的電子元件 之影像並於齡析顺取之影像純行視覺酬。這裡， 電子元件之影像係透過沿著導軌在「第〗圖」中的向上及向下方 向上移動托盤5，並透過向右及向左移動攝像機2而獲得。 當托盤5被傳送時，電子元件會由於托盤5之容納槽内的電 子元件之間的公差而發生微小的移動。如此會改變電子元件之位 置’進而導致在測#電子元件之精雜置時發生聽，或者導致 未測量出電子元件之準確位置。因此，會使視覺檢測之可靠性降 低’或使視覺檢測無法順利地進行。 【發明内容】 因此，鑒於上述問題，本發明之一目的在於提供一種能夠透 過簡化整體結構減小所占面積並能夠減少製造成本之視覺檢測設 備。 本發明之另一目的在於提供一種能夠使傳送托盤及電子元件— 之構造最小化進而大大地減少製造成本及尺寸之視覺檢測設備。

Description of the Invention: [Technical Field] The present invention relates to a visual inspection apparatus, and more particularly to a visual inspection apparatus capable of detecting the appearance of an electronic component loaded in a tray. [Prior Art] Electronic components, such as semiconductor packages, will be subjected to various duties such as power and external testing in the manufacturing process or before being put on the market, thereby increasing the yield and increasing the reliability of the product. For example, the material package can be fabricated by a number of processes such as a manufacturing process, a dicing process, and a packaging process on the wafer. If the defects in the semiconductor device are ignored and the subsequent processes are still performed unnecessarily, the overall manufacturing cost is increased. In order to avoid this problem, the above tests were performed prior to the main process to select qualified electronic components. These selected qualified electronic components are woven to follow the process. Most electronic components go through every test before they are put on the market. Therefore, only qualified electronic components can appear on the market, which increases the reliability of the product. The visual inspection device is used to carry a tray on which electronic components are mounted along a guide rail. Visual inspection is performed while moving up and down, and a camera can be moved in the right and left directions to detect electronic components loaded in the tray. Since the detection is performed when the tray on which the electronic component is loaded is transported, the position of the electronic component loaded in the tray 201033601 changes due to the tolerance between the electronic components in the receiving groove of the tray. Therefore, defects are generated when measuring the position of the electronic component. This will be explained in more detail below. Fig. 1 is a plan view showing an example of a visual inspection apparatus of the prior art. As shown in FIG. 1 , a conventional visual inspection device for detecting the appearance of an electronic component includes: a silk-filled fresh element 1 mounted to carry a tray 5 on which an electron transfer is mounted along a guide la; a camera 2 , the side to the electronic components that have been picked up n 6 to carry out the overview; pick! I 7, by transmitting electronic components to classify fully visually-detected electronic components; a tray transfer device (not shown in the drawings) is used to transport the tray 5; the sorting unit 4 is used along the guide rails The tray 5 is automatically transferred. However, the conventional visual inspection apparatus must be provided with a tray conveying device for automatically conveying the tray, and the tray loading unit 丨 and the sorting unit 4 must be respectively provided with φ rails la&4a. At the same time, a sorting device must be additionally provided after the visual inspection, for example, with an additional picking element 4 of the picking II 7. This can lead to over-complexity in the overall structure and can make manufacturing costs too high. In the case of mass production of electronic components, conventional visual inspection; equipment can be employed. However, when an expensive visual inspection device is used to produce a small number of electronic components 'when the overall manufacturing cost is increased, the productivity is lowered. In addition, conventional visual inspection devices occupy a relatively large installation space due to their complicated structure and large size. 5 201033601 In order to improve the reliability of the process of electronic components, the visual inspection equipment is installed in the clean room, which can remove dust and other substances in the clean room. If the size of the visual inspection device is increased, the area occupied by the visual inspection room will also increase. This will reduce the production of electronic components per unit area. A conventional visual inspection device obtains an image of an electronic component loaded in the tray 5 and performs a visual reward on the image obtained by the ageing. Here, the image of the electronic component is obtained by moving the tray 5 upward and downward along the guide rail in the "figure map" and moving the camera 2 to the right and left. When the tray 5 is conveyed, the electronic components are slightly moved due to the tolerance between the electronic components in the housing groove of the tray 5. This will change the position of the electronic component', which in turn causes the listener to be heard when the electronic component is miscellaneous, or the exact position of the electronic component is not measured. Therefore, the reliability of visual inspection is lowered or the visual inspection cannot be performed smoothly. SUMMARY OF THE INVENTION Therefore, in view of the above problems, it is an object of the present invention to provide a visual inspection apparatus capable of reducing the occupied area by simplifying the overall structure and reducing the manufacturing cost.
