覆蓋件(cover)780可拆卸地耦接支托器760上表面的一側。A cover 780 is detachably coupled to one side of the upper surface of the holder 760.
上述液晶注入單元操作如下。The above liquid crystal injection unit operates as follows.
首先，塗佈頭單元500位於液晶注入位置。提供於液晶注入單元700的感測器770偵測管件支撐管710的中心軸是否對應瓶蓋540之注入通道H的中心軸。First, the coating head unit 500 is located at the liquid crystal injection position. The sensor 770 provided to the liquid crystal injection unit 700 detects whether the central axis of the tube support tube 710 corresponds to the central axis of the injection channel H of the cap 540.
若管件支撐管710的中心軸對應瓶蓋540之注入通道H的中心軸，則致動器730向前移動滑件750，而使管件支撐管710插入瓶器530之瓶蓋540的注入通道H。滑件750沿著導軌740線性移動。If the central axis of the tube support tube 710 corresponds to the central axis of the injection channel H of the cap 540, the actuator 730 moves the slider 750 forward, and the tube support tube 710 is inserted into the injection channel H of the cap 540 of the bottle 530. . The slider 750 moves linearly along the rail 740.
在致動器730已操作一段時間而使管件支撐管710插入瓶蓋540的注入通道H後，儲存於液晶槽620的液晶透過管件650注入瓶蓋540的注入通道H。若注入瓶蓋540之注入通道H的液晶在瓶器530中達到預定程度，則停止透過管件650供應液晶。After the actuator 730 has been operated for a period of time to insert the tube support tube 710 into the injection channel H of the cap 540, the liquid crystal stored in the liquid crystal cell 620 is injected into the injection channel H of the cap 540 through the tube 650. If the liquid crystal injected into the injection path H of the cap 540 reaches a predetermined level in the bottle 530, the supply of the liquid crystal through the tube 650 is stopped.
接著，致動器730向後移動滑件750，而使管件支撐管710從瓶蓋540的注入通道H退出。Next, the actuator 730 moves the slider 750 rearward, and the tube support tube 710 is withdrawn from the injection passage H of the cap 540.
然而，於習知的液晶注入單元中，首先利用感測器決定液晶注入單元之管件支撐管710的中心軸是否對應提供於塗佈頭單元500之瓶器530之瓶蓋540之注入通道H的中心軸，之後移動管件支撐管710而插入瓶蓋540的注入通道H。於此程序中，當管件支撐管710彎曲或感測器發生故障時，管件支撐管710與插入管件支撐管710的管件650可能碰撞到瓶蓋540，而可能使管件650、管件支撐管710、以及瓶蓋540受損。However, in the conventional liquid crystal injection unit, first, the sensor determines whether the central axis of the tube support tube 710 of the liquid crystal injection unit corresponds to the injection channel H of the cap 540 of the bottle 530 of the coating head unit 500. The central shaft, after which the tube support tube 710 is moved, is inserted into the injection channel H of the cap 540. In this procedure, when the tube support tube 710 is bent or the sensor fails, the tube support tube 710 and the tube 650 inserted into the tube support tube 710 may collide with the cap 540, and the tube 650, the tube support tube 710, And the cap 540 is damaged.
再者，在突出管件支撐管710之管件650碰到瓶蓋540的狀況下，當透過管件650供應液晶時，液晶不會導入瓶蓋540的注入通道H，而是流到瓶器530外面，使得液晶可能滴落到平台200及基板上。Moreover, in a state in which the tube 650 protruding from the tube support tube 710 hits the cap 540, when the liquid crystal is supplied through the tube 650, the liquid crystal is not introduced into the injection channel H of the cap 540, but flows out of the bottle 530. The liquid crystal may be dropped onto the stage 200 and the substrate.
因此，本發明有鑑於先前技術所發生的問題，本發明之一目的在於提供用於液晶塗佈機之液晶注入單元，當支撐管件的管件支撐管要移動插入瓶器之瓶蓋的注入通道時，即使管件及管件支撐管碰到瓶器的瓶蓋，能避免管件、管件支撐管、以及瓶蓋受損。Accordingly, the present invention has been made in view of the problems occurring in the prior art, and an object of the present invention is to provide a liquid crystal injection unit for a liquid crystal coater, when the tube support tube supporting the tube member is to be moved into the injection passage of the bottle cap of the bottle holder.

以下說明根據本發明之液晶塗佈機之液晶注入單元之操作及效應。The operation and effect of the liquid crystal injection unit of the liquid crystal coater according to the present invention will be described below.
首先，塗佈頭單元500位於注入液晶的位置。利用提供於液晶注入單元的第一感測器S1，確定管件支撐管880的中心軸是否對應瓶蓋540之注入通道H的中心軸。First, the coating head unit 500 is located at a position where liquid crystal is injected. Whether the central axis of the tube support tube 880 corresponds to the central axis of the injection channel H of the cap 540 is determined by the first sensor S1 provided to the liquid crystal injection unit.
汽缸820操作一段預設時間，以向前移動滑件840。當滑件840向前移動時，支托器860與滑件840一起向前移動。當支托器860向前移動時，耦接支托器860的管件支撐管880及插入管件支撐管880的管件650插入瓶器530之瓶蓋540的注入通道H。The cylinder 820 is operated for a preset time to move the slider 840 forward. When the slider 840 moves forward, the holder 860 moves forward together with the slider 840. When the holder 860 moves forward, the tube support tube 880 coupled to the holder 860 and the tube member 650 inserted into the tube support tube 880 are inserted into the injection passage H of the cap 540 of the bottle holder 530.
儲存於液晶供應單元600之液晶槽620的液晶透過管件650供應到瓶器530。當供應預定量液晶到瓶器530時，停止透過管件650供應液晶。The liquid crystal that is stored in the liquid crystal cell 620 of the liquid crystal supply unit 600 is supplied to the bottle 530 through the liquid pipe 650. When a predetermined amount of liquid crystal is supplied to the bottle 530, the supply of the liquid crystal through the tube 650 is stopped.
接著，汽缸820向後移動滑件840，而使管件支撐管880從瓶蓋540的注入通道H退出。從瓶蓋540之注入通道H移出管件支撐管880後，塗佈頭單元500移到將液晶滴落到基板的位置。Next, the cylinder 820 moves the slider 840 rearward, and the tube support tube 880 is withdrawn from the injection passage H of the cap 540. After the tube support tube 880 is removed from the injection channel H of the cap 540, the coating head unit 500 is moved to a position where the liquid crystal is dropped onto the substrate.
同時，於下說明管件支撐管880沒有插入瓶蓋540的注入通道H且碰撞到瓶蓋540的案例。此發生於當管件支撐管880彎曲，或當第一感測器S1發生故障時，而使第一感測器S1偵測到管件支撐管880的中心軸對應瓶蓋540之注入通道H的中心軸，但實際上管件支撐管880的中心軸沒有對應瓶蓋540之注入通道H的中心軸。Meanwhile, a case in which the tube support tube 880 is not inserted into the injection passage H of the cap 540 and collided with the cap 540 will be described below. This occurs when the tube support tube 880 is bent, or when the first sensor S1 fails, so that the first sensor S1 detects that the central axis of the tube support tube 880 corresponds to the center of the injection channel H of the cap 540. The shaft, but in fact the central axis of the tube support tube 880 does not have a central axis corresponding to the injection channel H of the cap 540.
如圖7所示，當汽缸820向前移動滑件840時，管件支撐管880及插入管件支撐管880的管件650可能沒有插入瓶蓋540的注入通道H，而是可能碰撞到瓶蓋540。在管件650及管件支撐管880碰到瓶蓋540的狀況下，滑件840向前移動。支托器860在受到彈性構件870的彈力約束下相對於滑件840被向後推。因此，可避免損壞管件650、管件支撐管880、以及瓶蓋540。As shown in FIG. 7, when the cylinder 820 moves the slider 840 forward, the tube support tube 880 and the tube 650 inserted into the tube support tube 880 may not be inserted into the injection passage H of the cap 540, but may collide with the cap 540. In the case where the tube member 650 and the tube support tube 880 hit the cap 540, the slider 840 moves forward. The holder 860 is pushed rearward relative to the slider 840 under the constraint of the elastic force of the elastic member 870. Therefore, damage to the tube 650, the tube support tube 880, and the cap 540 can be avoided.
再者，若支托器860被向後推，則被第二感測器S2偵測到。當第二感測器S2偵測到支托器860被向後推，則不透過管件650供應液晶。因此，在管件650及管件支撐管880沒有插入瓶蓋540之注入通道H的狀態下，不會透過管件650供應液晶，因而避免液晶流出瓶器530。Furthermore, if the holder 860 is pushed backwards, it is detected by the second sensor S2. When the second sensor S2 detects that the holder 860 is pushed backward, the liquid crystal is not supplied through the tube 650. Therefore, in a state where the tube member 650 and the tube support tube 880 are not inserted into the injection passage H of the cap 540, the liquid crystal is not supplied through the tube member 650, thereby preventing the liquid crystal from flowing out of the bottle holder 530.
如上所述，本發明提供液晶塗佈機之液晶注入單元，其架構成當裝設有管件的管件支撐管要移到插入瓶器之瓶蓋的注入通道時，若管件及管件支撐管碰到瓶器之瓶蓋，則管件及管件支撐管在受到彈力約束下可被向後推，使得可避免管件、管件支撐管、以及瓶蓋受損。As described above, the present invention provides a liquid crystal injection unit of a liquid crystal coater, which is configured such that when the tube support tube provided with the tube member is moved to the injection passage of the bottle cap inserted into the bottle holder, if the tube member and the tube support tube meet With the bottle cap, the tube and the tube support tube can be pushed back under the constraint of the elastic force, so that the tube, the tube support tube and the bottle cap can be avoided.
再者，本發明提供液晶塗佈機之液晶注入單元，即使支撐管件的管件支撐管要移動插入瓶蓋的注入通道，若支撐管件的管件支撐管碰到瓶器的瓶蓋且沒有插入瓶蓋的注入通道，能偵測管件及管件支撐管沒有插入瓶蓋的注入通道。於此狀況，停止透過管件供應液晶。因此，可避免若在管件及管件支撐管沒有插入瓶蓋的注入通道而透過管件供應液晶，讓液晶流出瓶器而滴落到平台及基板的問題。Furthermore, the present invention provides a liquid crystal injection unit of a liquid crystal coater, even if the tube support tube supporting the tube member is moved into the injection passage of the bottle cap, if the tube support tube of the support tube member hits the bottle cap and the bottle cap is not inserted The injection channel can detect that the tube and the tube support tube are not inserted into the injection channel of the cap. In this case, the supply of the liquid crystal through the tube is stopped. Therefore, it is possible to avoid the problem that if the tube and the tube support tube are not inserted into the injection passage of the cap and the liquid crystal is supplied through the tube to allow the liquid crystal to flow out of the bottle to drip onto the platform and the substrate.
