玻璃基板1被上下拉伸後,側部夾緊裝置13〇的第8空壓 10氣缸131d動作,夾子131f分別夾緊玻璃基板1的側端部,並 使第7空壓氣缸131a動作,向兩側拉伸玻璃基板丨,使玻璃 基板1左右拉伸。 當用侧部夾緊裝置130的第7空壓氣缸丨31&左右拉伸玻 璃基板1時,通過上部及下部夾緊裝置110、12〇的第j上部 15夾具111與第1下部夾具112,玻璃基板1固定在一定位置的 狀態下,使第2上部夾具112與第1下部夾具122分別沿引導 軌道112a' 122a移動,使得玻璃基板丨在整個區域中左右拉 伸。由此,使玻璃基板1不撓曲,並使得振動最小化,當用 視頻元件200進行掃描時,取得清晰的影像。 20 用基板固定機構100夾緊並固定玻璃基板1後(S20),使 視頻元件移動機構300的第丨及第2移動電機36〇驅動使第1 及第2導螺杆310、340旋轉,從而使通過第1及第2導螺杆 310、340的旋轉作直線運動的移動架32〇、和與球狀螺母35〇 結合的視頻元件200,沿著第1及第2導螺杆310、34〇,從玻 18 1336397 璃基板1的一側移動到另一側,用視頻元件200的照明210與 多個攝影機(camera)220 ’掃描玻璃基板1的整個區域(S30)。 用視頻元件200的攝影機220掃描玻璃基板1的整個區 域(S30)後,根據用缺陷資料處理部400掃描得到的影像,對 5 玻璃基板1的缺陷個數、大小、位置等進行資料化處理(S40)。 關於玻璃基板1的處理資料通過監視器等顯示部500被 顯示到外部(S50)。 在將關於玻璃基板1的缺陷的資料顯示到外部的步驟 (S50)中,根據關於玻璃基板1的缺陷的資料,判斷缺陷大於 1〇 設定值、例如缺陷的個數、大小等設定值(S71),當玻璃基 板1的缺陷大於設定值時,經顯示部500顯示該玻璃基板1不 合格的内容(S72)。 將顯示部500中顯示的不合格的玻璃基板1取到外部, 不進入後續步驟(S80)。 15 在將關於玻璃基板1的缺陷的資料顯示到外部的步驟 (S50)中,若玻璃基板1的缺陷小於設定值,則爲了進行後續 步驟,從基板固定機構100中取出玻璃基板1,用移送夾子 (未圖示)夾緊玻璃基板1的上端,沿移送軌道(未圖示)移

After the entire area of the glass substrate 1 is scanned by the camera 220 of the video element 200 (S30), the number, size, position, and the like of the defects of the 5 glass substrate 1 are processed according to the image scanned by the defect data processing unit 400 ( S40). The processing data of the glass substrate 1 is displayed to the outside through the display unit 500 such as a monitor (S50). In the step (S50) of displaying the information on the defect of the glass substrate 1 to the outside, based on the data on the defect of the glass substrate 1, it is judged that the defect is larger than the set value of 1〇, for example, the number of defects, the size, and the like (S71) When the defect of the glass substrate 1 is larger than the set value, the display unit 500 displays the content of the glass substrate 1 that is unacceptable (S72). The defective glass substrate 1 displayed on the display unit 500 is taken outside, and does not proceed to the subsequent step (S80). 15 In the step (S50) of displaying the information on the defect of the glass substrate 1 to the outside, if the defect of the glass substrate 1 is smaller than the set value, the glass substrate 1 is taken out from the substrate fixing mechanism 100 for transfer, and transferred. A clip (not shown) clamps the upper end of the glass substrate 1, and is transferred along a transfer rail (not shown) or loaded into a cassette (not shown) of another device. 20 As described above, according to the preferred embodiment of the present invention, not only the inspection of the glass substrate is easily performed in the forming step, but also the time required for the inspection is shortened, and the occurrence of defects caused by physical contact with the glass substrate at the time of inspection is minimized, and The vibration of the glass substrate to be transferred is minimized within a defined depth of focus, and a proper inspection is performed. While the preferred embodiment of the invention has been described, the invention may be modified by those skilled in the art without departing from the scope of the invention.
