Description
本發明關於一種使用雷射的熔接密封裝置，且更具體地，關於一種使用雷射的熔接密封裝置，其中行進通過複數光纖之中選擇的某些光纖的雷射束係發射來用於利用熔塊的密封。BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a fusion sealing device using a laser, and more particularly to a fusion sealing device using a laser in which a laser beam system traveling through a selected one of a plurality of optical fibers is used for melting Block seal.
因為顯示裝置本身可以發射光，有機發光顯示裝置具有的優點是廣視角、優良對比度、與快速的反應速度，但是具有的問題是有機發光顯示裝置的短壽命、低發光效率、與發光顏色的劣化等等，這是因為當水或氧氣從周遭環境引入有機發光顯示裝置中時，電極材料的氧化、剝落等等。Since the display device itself can emit light, the organic light-emitting display device has the advantages of wide viewing angle, excellent contrast, and fast reaction speed, but has problems of short life, low luminous efficiency, and deterioration of luminescent color of the organic light-emitting display device. Etc., this is because when water or oxygen is introduced into the organic light-emitting display device from the surrounding environment, the electrode material is oxidized, peeled off, and the like.
因此，當製造有機發光顯示裝置時，有機發光顯示裝置通常已經密封，以隔絕於外部且防止水滲透。另外，已經提出一種方法，使用熔塊作為密封材料來用於此種密封方法，以改良有機發光顯示裝置中上下配置的基板之間的緊密黏著與緊密密封。Therefore, when manufacturing an organic light emitting display device, the organic light emitting display device is usually sealed to be isolated from the outside and prevent water from penetrating. In addition, a method has been proposed in which a frit is used as a sealing material for such a sealing method to improve the close adhesion and tight sealing between the substrates disposed above and below in the organic light-emitting display device.
第1圖為一視圖，顯示了使用雷射的傳統熔接密封方法的範例。Figure 1 is a view showing an example of a conventional fusion sealing method using a laser.
在利用熔塊12來密封有機發光顯示裝置1的該方法中，熔塊12以封閉環路的形式施加在有機發光顯示裝置1的外側上，且雷射束L係發射至基板11上的熔塊12，同時雷射束L移動，使得熔塊12可以硬化，藉此將被熔塊12所圍繞的有機發光顯示裝置1密封。In the method of sealing the organic light-emitting display device 1 with the frit 12, the frit 12 is applied on the outer side of the organic light-emitting display device 1 in the form of a closed loop, and the laser beam L is emitted to the substrate 11 for melting. At block 12, the laser beam L is moved so that the frit 12 can be hardened, whereby the organic light-emitting display device 1 surrounded by the frit 12 is sealed.
但是，使用雷射的傳統熔接密封裝置處理熔塊12，同時將行進通過光纖的單一雷射束L沿著熔塊12被施加的方向移動，且因此具有的問題是處理整個熔塊12所花的時間會延長。另外，因為對於大尺寸電視或類似的有機發光顯示裝置的漸增需求會導致熔塊12的路徑變得較長，傳統熔接密封方法具有的問題是處理整個熔塊12所花的時間會延長，且實質上降低了生產效率，因為發射至熔塊的單一雷射束係移動來用於熔化且硬化該熔塊。However, the frit 12 is treated using a conventional fusion seal of a laser while a single laser beam L traveling through the fiber is moved in the direction in which the frit 12 is applied, and thus has the problem of processing the entire frit 12 The time will be extended. In addition, since the increasing demand for a large-sized television or the like organic light-emitting display device causes the path of the frit 12 to become long, the conventional fusion sealing method has a problem that the time taken to process the entire frit 12 is prolonged, And the production efficiency is substantially reduced because a single laser beam emitted to the frit moves to melt and harden the frit.
因此，本發明係構思來解決上述問題，且本發明的一態樣係提供一種使用一雷射的熔接密封裝置，其中使用複數光纖來處理較大單位面積的熔塊，藉此減少處理整個熔塊所花的時間並且改良生產效率。Accordingly, the present invention is conceived to solve the above problems, and an aspect of the present invention provides a fusion sealing device using a laser in which a plurality of optical fibers are used to process a large unit area of the frit, thereby reducing the entire melting process.

參見第2圖與第3圖，根據範例實施例之使用雷射的熔接密封裝置100將行進通過複數光纖之中選擇的某些光纖的雷射束發射至熔塊，來用於利用熔塊的密封。熔接密封裝置100包括雷射輸出單元110、光纖束單元120、轉移單元、與控制器130。Referring to Figures 2 and 3, a laser-fired sealing device 100 is used to transmit a laser beam traveling through selected fibers of a plurality of fibers to a frit for use with a frit. seal. The fusion seal device 100 includes a laser output unit 110, a fiber bundle unit 120, a transfer unit, and a controller 130.
根據範例實施例之使用雷射的熔接密封裝置100將敘述作為使用雷射來將有機發光顯示裝置的熔塊12熔化與硬化的範例。在一般的有機發光顯示裝置中，熔塊12施加於一對面向彼此的基板11之間，且有機發光顯示裝置1由熔塊12所圍繞。雷射束L發射至基板11之間的熔塊12，使得熔塊12可熔化與硬化。因此，設置於由一對基板11與熔塊12所分隔的內部空間中的有機發光顯示裝置1從外部被密封。The fusion sealing device 100 using a laser according to an exemplary embodiment will be described as an example of melting and hardening the frit 12 of the organic light-emitting display device using a laser. In a general organic light-emitting display device, a frit 12 is applied between a pair of substrates 11 facing each other, and the organic light-emitting display device 1 is surrounded by the frit 12. The laser beam L is emitted to the frit 12 between the substrates 11, so that the frit 12 can be melted and hardened. Therefore, the organic light-emitting display device 1 provided in the internal space partitioned by the pair of substrates 11 and the frit 12 is sealed from the outside.
在此範例實施例中，熔塊12可包括添加有粉末性有機材料或固體玻璃的膠化玻璃，膠化玻璃由發射的雷射束L來硬化。In this exemplary embodiment, the frit 12 may comprise a gelled glass to which a powdered organic material or solid glass is added, the gelled glass being hardened by the emitted laser beam L.

The plurality of laser diodes 111 are connected one-to-one to the plurality of optical fibers 121 provided in the fiber bundle unit 120 (to be described later). A laser beam L generated by a laser diode 111 is emitted to the frit 12 through an optical fiber 121 connected to the laser diode 111.
光纖束單元120包括複數光纖121，每一光纖121具有一輸入端與一輸出端，通過該輸入端，輸入從雷射輸出單元110輸出的雷射束L，且通過該輸出端，發射雷射束L至熔塊12。The fiber bundle unit 120 includes a plurality of optical fibers 121 each having an input end and an output end through which a laser beam L output from the laser output unit 110 is input, and a laser beam is emitted through the output end. The bundle L is to the frit 12.
在構成光纖束單元120的複數光纖121之中選擇某些光纖121，且雷射束L行進通過選擇的某些光纖121並且發射至熔塊12。複數光纖121係配置為一矩形，該矩形具有在光纖束單元120中的複數水平與垂直線。Some of the optical fibers 121 are selected among the plurality of optical fibers 121 constituting the bundle unit 120, and the laser beam L travels through some of the selected optical fibers 121 and is emitted to the frit 12. The plurality of optical fibers 121 are configured as a rectangle having a plurality of horizontal and vertical lines in the bundle unit 120.
第2圖與第3圖例示的光纖束單元120是複數光纖121係配置為6列與6行的一矩形，但不限於此。替代地，用於複數光纖的列與行的數量可以改變。例如，複數光纖可配置為8列與8行的一方形，或配置為圓形。The fiber bundle unit 120 illustrated in FIGS. 2 and 3 is a rectangular shape in which the plurality of optical fibers 121 are arranged in six columns and six rows, but is not limited thereto. Alternatively, the number of columns and rows for a plurality of fibers can vary. For example, the plurality of fibers can be configured as a square of 8 columns and 8 rows, or configured as a circle.
另外，可在光纖束單元120之下提供複數聚光透鏡(未示)與主體管(未示)，聚光透鏡用於將從光纖121發射的雷射束L聚光至熔塊12中，且主體管用於容納複數聚光透鏡於其中。In addition, a plurality of collecting lenses (not shown) and a main body tube (not shown) may be provided under the fiber bundle unit 120, and the collecting lens is used to collect the laser beam L emitted from the optical fiber 121 into the frit 12, And the main body tube is for accommodating a plurality of concentrating lenses therein.
轉移單元(未示)轉移光纖束單元120。A transfer unit (not shown) transfers the fiber bundle unit 120.
從光纖束單元120發射雷射束L，光纖束單元120安裝在起重台架結構或類似者中，且藉由轉移單元，將光纖 束單元120轉移於沿著熔塊12的X方向或Y方向中。轉移光纖束單元120來用於發射雷射束L的轉移單元可使用線性馬達、結合有旋轉馬達與滾珠螺桿的結構、或本領域中熟習技藝者所熟知的相似結構。因此，將省略轉移單元的更多詳細敘述。The laser beam L is emitted from the fiber bundle unit 120, and the fiber bundle unit 120 is mounted in a gantry structure or the like, and the optical fiber is transferred by the transfer unit The beam unit 120 is transferred in the X direction or the Y direction along the frit 12. The transfer unit for transferring the bundle unit 120 for launching the laser beam L may use a linear motor, a structure incorporating a rotary motor and a ball screw, or a similar structure well known to those skilled in the art. Therefore, a more detailed description of the transfer unit will be omitted.
在此範例實施例中，轉移單元包括馬達與編碼器(未示)，馬達用於供應驅動力，以轉移光纖束單元120，且編碼器用於感測正被轉移的光纖束單元120的位置。In this exemplary embodiment, the transfer unit includes a motor and an encoder (not shown) for supplying a driving force to transfer the fiber bundle unit 120, and the encoder is for sensing the position of the fiber bundle unit 120 being transferred.
控制器130從轉移單元接收編碼器信號，且控制器130控制雷射輸出單元110，使得雷射束L可僅行進通過配置於對應於熔塊12的形狀之位置處的光纖121。The controller 130 receives the encoder signal from the transfer unit, and the controller 130 controls the laser output unit 110 such that the laser beam L can travel only through the optical fiber 121 disposed at a position corresponding to the shape of the frit 12.
參見第3圖，熔塊12係沿著其施加方向而先分成複數區段P1、P2、P3與P4，且控制器130事先儲存區段位置資訊，區段位置資訊指示個別劃分之區段P1、P2、P3與P4的開始位置。另外，相關於每一劃分之區段P1、P2、P3與P4事先儲存：關於配置於對應於熔塊12的形狀之位置中且用於發射雷射束L的光纖121a，以及配置於偏離於熔塊12的位置中且並未用於發射雷射束L的光纖121b的設定資訊。Referring to FIG. 3, the frit 12 is first divided into a plurality of sections P1, P2, P3, and P4 along the direction in which it is applied, and the controller 130 stores the section position information in advance, and the section position information indicates the section P1 of the individual division. , P2, P3 and P4 start position. In addition, the sections P1, P2, P3, and P4 associated with each division are stored in advance with respect to the optical fiber 121a disposed in the position corresponding to the shape of the frit 12 and used to emit the laser beam L, and are disposed offset from The position of the frit 12 is not used to set information of the optical fiber 121b that emits the laser beam L.
在量產之前針對設定此種處理情況或類似者的測試運轉程序中，處理熔塊12所需的資訊係事先儲存在控制器130中，且之後，實質上處理熔塊12。當轉移單元在施加熔塊12的方向中轉移光纖束單元時，轉移單元的編碼器信號與控制器130中所儲存的區段位置資訊相比較。若能判定是否從轉移單元的編碼器信號所獲得之光纖束單元的位置資訊實 質上等於控制器130中所儲存的區段位置資訊，則也可以判定是否光纖束單元120到達對應的區段。在此種判定之後，控制雷射輸出單元110，使得雷射束L可從配置於對應於熔塊12的形狀之位置處的光纖121a所連接的該雷射二極體111來產生。In the test operation procedure for setting such a processing situation or the like before mass production, the information required to process the frit 12 is previously stored in the controller 130, and thereafter, the frit 12 is substantially processed. When the transfer unit transfers the fiber bundle unit in the direction in which the frit 12 is applied, the encoder signal of the transfer unit is compared with the segment position information stored in the controller 130. If it can be determined whether the position information of the fiber bundle unit obtained from the encoder signal of the transfer unit is Qualitatively equal to the segment position information stored in the controller 130, it can also be determined whether the fiber bundle unit 120 reaches the corresponding segment. After such determination, the laser output unit 110 is controlled such that the laser beam L can be generated from the laser diode 111 to which the optical fiber 121a disposed at a position corresponding to the shape of the frit 12 is connected.
藉由控制雷射輸出單元110，光纖121係如同第3圖所示地根據在個別劃分之區段P1、P2、P3與P4中之熔塊12的形狀來選擇，藉此處理熔塊12。By controlling the laser output unit 110, the optical fiber 121 is selected according to the shape of the frit 12 in the individually divided sections P1, P2, P3 and P4 as shown in Fig. 3, whereby the frit 12 is processed.

影像拍攝單元240包括攝影機(未示)與發光單元(未示)，攝影機具有成像感測器來拍攝熔塊12的影像，且發光單元用於照亮熔塊12，且影像拍攝單元240係安裝至轉移單元並且與光纖束單元120一起被轉移。The image capturing unit 240 includes a camera (not shown) and a light emitting unit (not shown), the camera has an imaging sensor to capture an image of the frit 12, and the light emitting unit is used to illuminate the frit 12, and the image capturing unit 240 is mounted. To the transfer unit and with the fiber bundle unit 120 is transferred.
控制器230接收影像拍攝單元240的影像信號，且控制器230控制雷射輸出單元110，使得雷射束L可僅行進通 過配置於對應於熔塊12的形狀之位置處的光纖121。The controller 230 receives the image signal of the image capturing unit 240, and the controller 230 controls the laser output unit 110 so that the laser beam L can only travel through The optical fiber 121 disposed at a position corresponding to the shape of the frit 12 is passed.
參見第3圖，控制器230根據像素來分析從影像拍攝單元240接收的影像信號I1、I2、I3與I4，所以可區分出對應於熔塊12的熔接區域與偏離熔塊12的非熔接區域。透過在來自影像拍攝單元的影像信號I1、I2、I3與I4中的灰階分析或類似者，可區分出熔接區域與非熔接區域。另外，控制器230事先儲存關於影像拍攝單元240的視野(FOV,field of view)中的像素分別匹配於光纖束單元120的光纖121的資訊。例如，控制器230事先儲存關於影像拍攝單元240的視野中的某列與某行處的像素匹配於光纖束單元120的某列與某行處的光纖121的資訊。Referring to FIG. 3, the controller 230 analyzes the image signals I1, I2, I3, and I4 received from the image capturing unit 240 according to the pixels, so that the welded regions corresponding to the frit 12 and the non-welded regions offset from the frit 12 can be distinguished. . The welded area and the non-fused area can be distinguished by gray scale analysis or the like in the image signals I1, I2, I3, and I4 from the image capturing unit. In addition, the controller 230 stores in advance information about the pixels in the field of view (FOV, field of view) of the image capturing unit 240 that are matched to the optical fibers 121 of the fiber bundle unit 120, respectively. For example, the controller 230 stores in advance information about a certain column in the field of view of the image capturing unit 240 and a pixel at a certain row matching the optical fiber 121 at a certain column of the fiber bundle unit 120 and a certain line.
在量產之前針對設定此種處理情況或類似者的測試運轉程序中，處理熔塊12所需的資訊係事先儲存在控制器230中，且之後，實質上處理熔塊12。當轉移單元在施加熔塊12的方向中轉移光纖束單元120時，影像拍攝單元240拍攝熔塊12的影像。控制器230根據像素來分析從影像拍攝單元240接收的影像信號I1、I2、I3與I4，並且控制器230區分出配置有熔塊12的熔接區域，藉此決定對應於熔接區域的像素的位置。之後，使用影像拍攝單元240的視野中的像素與光纖121之間的匹配資訊，來決定配置於對應於熔接區域的位置處的光纖121a，且控制雷射輸出單元110，使得連接至所決定之光纖121a的雷射二極體111可發射雷射束L。In the test operation procedure for setting such a processing situation or the like prior to mass production, the information required to process the frit 12 is previously stored in the controller 230, and thereafter, the frit 12 is substantially processed. When the transfer unit transfers the fiber bundle unit 120 in the direction in which the frit 12 is applied, the image capturing unit 240 takes an image of the frit 12. The controller 230 analyzes the image signals I1, I2, I3, and I4 received from the image capturing unit 240 according to the pixels, and the controller 230 distinguishes the welded regions in which the frit 12 is disposed, thereby determining the position of the pixel corresponding to the welded region. . Thereafter, using the matching information between the pixels in the field of view of the image capturing unit 240 and the optical fiber 121, the optical fiber 121a disposed at a position corresponding to the welded region is determined, and the laser output unit 110 is controlled so as to be connected to the determined The laser diode 111 of the optical fiber 121a can emit the laser beam L.
