Description

液晶盒成盒装置及其方法 技术领域
本发明是有关于一种液晶盒成盒装置及其方法，特别是有关于一种将基板的对位、真空压合及密封胶固化等装置整合成一体的液晶盒成盒装置及其方法。
 背景技术
目前在液晶面板的液晶滴入制造过程(One Drop Filling，ODF)，相关设备包含了密封胶点胶设备、液晶滴入设备、真空压合设备、密封胶固化设备等。当薄膜晶体管基板(Thin-Film Transistor，TFT)经过密封胶点胶及液晶滴入等程序后，即会与彩色滤光片基板(Color Filter)进行真空压合程序，当完成真空压合程序并将用以封住液晶的密封胶固化，即完成液晶盒(liquid crystal cell)的成盒程序。
现有液晶面板进行真空压合及密封胶固化程序涉及了真空压合设备、密封胶固化设备以及在制造过程中用来运送基板的机械手臂。所述薄膜晶体管基板与彩色滤光片基板会分别通过机械手臂送入真空压合设备，通过对位、抽气等动作，在真空状态下压合成一基板组件。现有真空压合设备在执行真空压合所耗时间约为100秒左右。由于真空压合设备花费在基板投入的时间约30秒，此外从常压状态抽气减至真空状态0.2帕(Pa)，一般也需35~45秒。由此可见，真空压合程序所耗费的时间主要是花在了基板搬入及抽气动作。
完成真空压合程序后，所述基板组件接着会回到常压状态并通过机械手臂送入密封胶固化设备。一般来说，运送时间为1~2分钟。由于基板组件的密封胶在回到常压状态后需在一定时间内完成固化(一般为5~10分钟)，否则仍未固化的密封胶将会受外界大气压力冲入而使液晶外泄。同时，所述仍未固化的密封胶也容易使两基板产生对位偏移，而影响到制造质量。因此，送入密封胶固化设备及进行密封胶固化的时间管控要求甚严。
再者，随着液晶面板尺寸的增大，所述密封胶固化设备为确保紫外光照射面积及均一性，遂采用更大功率的紫外光灯管，且灯管数也同样增加。由于灯管价格昂贵且需耗费大量电力及需使用冷却装置；同时还需配合采用光罩以保证制品安全。因此，现有的密封胶固化设备所需的设备成本相当可观。

请参照图1所示，本发明一较佳实施例的液晶盒成盒装置的示意图，其主要包含一预对位真空腔室1、一真空压合腔室2及一密封胶固化腔室3。
所述预对位真空腔室1供接收待压合的一第一基板40与一第二基板41，以运送所述第一基板40与所述第二基板41并同时维持所述第一基板40与所述第二基板41在位置上相互对应，且于接受所述第一基板40与所述第二基板41之后将内部气压降低至一第一预设值，所述第一预设值接近真空，优选是1Pa。所述预对位真空腔室1具有一第一运送机构11及一第二运送机构12，两者统称为一梳式运送***。所述第一运送机构11位于所述预对位真空腔室1的顶部，用以运送所述待压合的第一基板40。请参考图2所示，所述第一运送机构11具有至少两第一吸附条组110A、110B，其中所述至少两第一吸附条组110A、110B交替来回运送数个所述第一基板40。详细地说，每一所述第一吸附条组110A、110B由数个吸附条111A、111B组成，且所述第一吸附条组110A的吸附条111A与另一第一吸附条组110B的吸附条111B交替间隔平行排列，故所述至少两第一吸附条组110A、110B可互不影响地来回移动，并利用吸附力稳定运送所述待压合的第一基板40。每一所述吸附条111A、111B如图3所示，其两端分别设有孔洞1110，且其底面形成一与所述孔洞1110连通的长槽1111，所述孔洞1110分别连接一抽气管1112，当吸附条111A、111B底面接触所述第一基板40的顶面时，利用所述抽气管1112抽气而在所述长槽1111处形成真空吸力，如此即可使所述吸附条111A、111B能紧密稳固的吸附所述第一基板40。接着，得以控制所述吸附条111A、111B移动，来进行所述第一基板40的运送。
所述第二运送机构12位于所述预对位真空腔室1的底部而对应所述第一运送机构11，用以运送所述待压合的第二基板41。对应所述第一运送机构11的构造，所述第二运送机构12亦具有至少两第二吸附条组，其中所述至少两第二吸附条组交替来回运送数个所述第二基板41。更详细地，每一所述第二吸附条组由数个吸附条组成，且所述第二吸附条组的吸附条与另一第二吸附条组的吸附条交替间隔平行排列，故所述至少两第二吸附条组可互不影响地来回移动，并利用吸附力稳定运送所述待压合的第二基板41。
所述真空压合腔室2是连接所述预对位真空腔室1，以接收来自所述预对位真空腔室1的所述第一基板40与所述第二基板41，并将内部气压值从所述第一预设值降至一接近真空状态的第二预设值，所述第二预设值优选是0.2Pa。所述真空压合腔室2还包含有一压合装置(图中未示)以压合所述第一基板40与所述第二基板41，所述第一基板40与第二基板41压合后成为一基板组件42(assembly)，其中所述基板组件42包含至少一密封胶(sealant)400，所述密封胶400位于所述第一基板40与第二基板41之间，所述密封胶400用以封装预先填入的液晶，所述密封胶400通常选自紫外线固化型密封胶(UV-cured seal)，而此时的所述密封胶400仍呈半固化状态并具有粘性，因此在受压后可用以粘结在所述第一基板40与第二基板41之间。又所述密封胶400的宽度范围是0.5毫米至2毫米。所述真空压合腔室2还于所述第一基板40与所述第二基板41压合完成后令内部气压开放至常压状态。所述真空压合腔室2与所述预对位真空腔室1之间设有一真空隔断***(图中未示)，所述真空隔断***可于真空压合腔室2将气压从1Pa降至0.2Pa时，隔断所述真空压合腔室2与所述预对位真空腔室1之间的连通关系，以使所述真空压合腔室2形成密闭空间。再者，所述真空压合腔室2还包含有一运输装置20。所述运输装置20隐藏于所述真空压合腔室2的底部，待所述第一基板40与第二基板41压合成为所述基板组件42且气压开放至常压之后上升至一预定位置，以承载并运出所述基板组件42。所述运输装置20优选为一滚轮式运输装置。
所述密封胶固化腔室3连通所述真空压合腔室2，以接收来自所述真空压合腔室2的所述基板组件42。所述密封胶固化腔室3包含至少一紫外光点光源30(UV spot light source)位于所述密封胶固化腔室3的顶部。同时参考图4所示，所述至少一紫外光点光源30是一特殊的移动式光源，其能够在所述基板组件42的上方移动并照射所述基板组件42的表面，以固化所述基板组件42内待固化的至少一密封胶400；其中所述紫外光点光源30是对应所述基板组件42内的至少一密封胶400的位置移动，且所述紫外光点光源30在所述基板组件42上的照射区域的宽度等于所述密封胶400的宽度。所述紫外光点光源30优选是紫外光发光二极管(Ultraviolet Light Emitting Diode)。再者，本实施例中，所述密封胶固化腔室3包含多个并排的所述紫外光点光源30，其在同一移动路径上移动照射同一所述密封胶400，其中所述移动路径的形状是对应于所述密封胶400的形状。
举例来说，如图4所示，若所述基板组件42具有3x3个所述密封胶400及液晶材料区域且所述密封胶固化腔室3设有3组所述紫外光点光源30时，3组所述紫外光点光源30先依3个所述密封胶400的形状(矩形)，在预定移动路径上矩形移动照射3个所述密封胶400，在照射完成后，再照射另3个所述密封胶400，并依相同方式照射所有所述密封胶400。
如图5所示，本发明液晶盒成盒方法主要包含下列步骤：
S100：将待压合的一第一基板40及一第二基板41送入所述预对位真空腔室1；
S101：利用所述预对位真空腔室1的梳式运送***使所述第一基板40及第二基板41对位；
S102：于所述预对位真空腔室1将内部气压预先降至一第一预设值；
S103：利用所述梳式运送***将所述第一基板40及第二基板41送入所述真空压合腔室2；
S104：于所述真空压合腔室2将内部气压从所述第一预设值降至一更接近真空状态的第二预设值；
S105：利用所述真空压合腔室2的压合装置压合所述第一基板40及第二基板41而成所述基板组件42；
S106：利用所述真空压合腔室2的运输装置20将所述基板组件42送入所述密封胶固化腔室3；以及
S107：利用所述密封胶固化腔室3的至少一紫外光点光源30在所述基板组件42上方移动并照射所述基板组件42表面，以利用紫外光固化所述基板组件42内的至少一密封胶400。
前述过程中，所述梳式运送***进行基板的对位与运送，其第一运送机构11(或第二运送机构12)通过其第一吸附条组110A、110B(或第二吸附条组)的交错运送，可在一基板送入所述真空压合腔室2时，同时由另一第一吸附条组(或第二吸附条组)接收由外部送入预对位真空腔室1的下一基板，从而节省整体的作业时间。且运送到所述真空压合腔室2的过程无需使用机械手臂，使所述真空压合腔室2的腔体容积得以缩小，同时缩短降低内部气压所花费的抽气时间。再者，压合后的基板组件42采用滚轮式运输装置送入密封胶固化腔室3，同样有助于加快作业时间并降低液晶泄漏的风险。再者，相较于传统采用紫外光灯管(UV Lamp)需耗费大量电能且维护成本昂贵，本发明的密封胶固化腔室3采用所述移动式的紫外光点光源30固化所述基板组件42内的密封胶400，减少了光源所需数量，降低了密封胶固化设备的制造与维护成本，并节约了电能。
综上所述，本发明有别于现有技术，将真空压合与密封胶固化两个制造步骤所使用到的设备与运送***整合成一体，其中采用所述梳式运送***及所述移动式的紫外光点光源30，***整体省去了机械手臂与减少光源数量，可有效缩小设备的整体体积、减少设备成本，同时降低成盒基板的贴合时间(Tact Time)。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，上述实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
