如图1和图3所示，所述成型腔103还包括位于成型腔103的下部的玻璃带腔1033。所述隔板104的末端1041位于玻璃带腔1033的上部；所述玻璃带腔1033上端为熔融玻璃下拉出口105；所述下拉出口105呈双缝结构且该下拉出口105与第一容腔1031和第二容腔1032的底部连通。熔融玻璃在所述第一容腔和第二容腔内从上到下流动且第一容腔和第二容腔内的熔融玻璃同时流入玻璃带腔1033。
所述下拉出口105位于成型腔103上部的第一容腔1031和第二容腔1032与位于成型腔103下部的玻璃带腔1033之间。下拉出口105为双缝结构主要是指该处的宽度，相对于第一容腔1031、第二容腔1032和玻璃带腔1033的宽度而言，比较窄，熔融玻璃在该处呈挤压状态然后沿着隔板104进入玻璃带腔1033中。由图1和图3可知，下拉出口105的双缝结构是形成在两个外板101,102和隔板104之间的最窄处。在一实施方式中，下拉出口105与隔板的末端1041相邻，但并未不位于隔板的末端1041的底部。
熔融玻璃进入到第一外板101和第二外板102之间的成型腔103内，且通过隔板104将成型腔103内的熔融玻璃分成两部分；两部分熔融玻璃分别在第一容腔1031和第二容腔1032内且沿着隔板104的侧面同时向玻璃带腔1033方向流动；从第一容腔1031和第二容腔1032流动到隔板的末端1041(即熔融玻璃下拉出口105处)的熔融玻璃在隔板的末端的底部合二为一并在玻璃带腔1033内向下拉制形成玻璃带，如图3所示。
所述第一外板101和第二外板102顶部所在位置的高度高于隔板104顶部所在位置的高度；通过设置隔板104的顶部低于外板的顶部，能保证隔板104两侧熔融玻璃的均匀性。此外，所述隔板104具有两个相对的侧面，一个侧面面向第一外板101，另一个侧面面向第二外板102。
所述隔板104与第一外板101和第二外板102相对的侧面分别固定设置有第一温度传 感器201，所述第一外板101和第二外板102与隔板104相对的侧面分别固定设置有第一温度传感器201及温控单元202；二者均与信号处理器205电性连接；温控单元202为第一调节电极，位于成型腔103的内壁，通过调节电极能够控制成型腔内的温度。所述调节电极可直接购买市场上销售的能够调温的成品。

所述第一调节电极接收信号处理器205的指令，并进行温度调整。
所述第一目标温度是为了控制第一容腔1031和第二容腔1032内的熔融玻璃的温度而根据实际的需求设定的。
熔融玻璃位于成型腔103内，熔融玻璃在第一容腔1031和第二容腔1032内的流动及温度调节通过其内壁设置的温控单元202实现，加热设备体积小，减少热能流动损失，降低能耗，提高产品产出效率。隔板104的侧面、外板的内表面设置的第一温度传感器201能对流经其内部的熔融玻璃进行测温，测温的数据反馈至信号处理器205，信号处理器205控制温控单元202加热，灵活调节熔融玻璃流动时的温度。成型腔103的内部满布第一调节电极，控制第一调节电极分区控制温度，有效调节熔融玻璃的物性，减少成型过程中的纹理，减少不良品发生。拉制过程与外界接触面减少，仅限于出口拉制处，减少污染物的附着，提高产出品的物性。
所述玻璃带腔1033的两侧分别固定设置有物性感应器和第二温度传感器204，所述物性感应器和第二温度传感器204均与信号处理器205电性连接。所述物性感应器采用照相机。所述第二温度传感器采用常规的温度传感器即可。所述的至少一个程序还包括：

信号处理器205接收物性感应器拍摄的照片，并从中分析玻璃带的厚度、透光率、杂质含量、以及流动速度等参数，判断这些参数是否符合预定范围；当不符合时，则控制第一调节电极，通过调节成型腔103内不同区域的温度，来改善这些参数。
所述第二温度传感器接收实时采集温度，并将采集到的温度发送给信号处理器205的指令；
信号处理器205还接收第二温度传感器采集的温度，并将其与设定的第二目标温度进行比较；当采集的温度低于第二目标温度时，发送指令给第一调节电极；
所述第一调节电极接收信号处理器205的指令，并对成型腔内的温度进行调整。
所述第二目标温度是为了控制玻璃带腔1033内的玻璃带的温度而根据实际的需求设定的。
所述第一外板101和第二外板102均呈折型且二者结构相同；如图2a所示，每个外板均包括竖直板体106和倾斜板体107，所述倾斜板体107位于竖直板体106的底部，所述倾斜板体107的顶部与隔板104之间的距离大于其底部与隔板104之间的距离；即所述成型腔103从上到下逐渐缩小。所述倾斜板体107与隔板104侧面相对的一侧为倾斜平面或者倾斜曲面中的任一种。
如图2a和图2b所示，所述玻璃带腔1033的上部为上宽下窄的大致V型结构。如图1和图3所示，所述隔板的末端1041为上宽下窄的V型结构；便于引导熔融玻璃从上到下沿着隔板104流入玻璃带腔1033中。
玻璃成型器本体100包括第一外板101和第二外板102，用于将上一道工序产生的呈液态状的熔融玻璃，沿着玻璃成型器本体100的中心平面(即隔板形成的平面1042)向下拉制成型。隔板104用于将上一道该工序的熔融玻璃在成型腔103中划分为2个区域(即第一容腔和第二容腔)，在隔板的末端1041处，第一容腔1031和第二容腔1032两区的熔融玻璃合二为一，然后在玻璃带腔1033处向下拉制形成玻璃带。隔板104的高度略低于第一外板101和第二外板102，以保证两侧熔融玻璃均匀。玻璃成型器本体100上部第一外板101和第二外板102的倾斜板体107的形状可以为：与隔板104侧面相对一侧形成倾斜平面的双直线型外板108，如图2a所示；也可以为：与隔板104侧面相对一侧形成倾斜曲面的双曲线型外板109，如图2b所示。双曲线型外板109可以保证熔融玻璃保持更好的流动性和均匀性。玻璃成型器本体100，两侧内壁及隔板104两侧外壁(即两侧面)，装有第一温度传感器201，及温控单元202，在横向和纵向上划成多个区域。
不同感应区相关信号通过数模转换器203传至信号处理器205，再控制各不同区域温控单元202(第一调节电极)，调整温度以保证不同区域的熔融玻璃的流动性及物理特性。同时，隔板的末端1041下方，两侧熔融玻璃拉制汇合后，形成玻璃带，玻璃带两侧设置四组物性感应器和第二温度传感器204，感应玻璃带的物理特性(包括温度，透光度，厚度，流速等)，将信号反馈给信号处理器205。再控制各不同区域温控单元，调整温度以保证不同区域的玻璃液体流动性及物理特性。
在一种实施方式中，如图3所示，成型腔103的上部的底部(即第一容腔1031和第二容腔1032的底部)出口处竖直设有两个与第一外板101和第二外板102相对应的上导料板110，上导料板110与第一外板101和第二外板102之间分别滑动设有横隔板111。
所述横隔板111能够与隔板104之间形成所述熔融玻璃的下拉出口105，用于控制玻璃带的宽度。例如，若希望得到宽度为5mm的玻璃带，那么可以控制各个横隔板111与隔板104的间距为2.5mm，从而使得熔融玻璃到达隔板104的底部所形成的玻璃带的宽度为5mm。在本实施方式中，横隔板111与隔板104之间的缝隙即为所述的双缝结构。
此外，所述所述横隔板111还能够与隔板104接触，以截断熔融玻璃。当切割装置进 行切割时，阻止熔融玻璃继续进入玻璃带腔1033中。
上导料板110的底部与隔板104的底部(即隔板的末端的底部)大致平齐。
两个上导料板110的下方对应设有两个下导料板112；上导料板110和下导料板112之间设有切割丝113；切割丝113可采用铂金切割丝；切割丝113的两端分别与横切装置4连接，以驱动切割丝113对初步成型的玻璃带进行切割。
所述下导料板112的下方设有抓取装置5。
所述两个上导料板110之间形成的空间构成所述玻璃带腔1033的一部分；两个下导料板112之间形成的空间也构成所述玻璃带腔1033的一部分。
所述物性感应器和第二温度传感器204设置在上导料板110和下导料板112的内壁，从而监控玻璃带的物性参数和温度。
上导料板110和下导料板112的内部还可以设置第二调节电极，对玻璃带腔内进行温度调节。玻璃带在玻璃带腔中的温度可能会影响玻璃带的最终成型效果；因此在此设置温度调节。
通过设置横隔板111，能够控制下拉熔融玻璃的流量；通过设置上导料板110和下导料板112，能够互相配合，使拉制成形的玻璃带顶部仍保持为热态，方便切割丝113对热态下的玻璃带进行切割。通过设置切割丝113和横切装置4，能够沿着上导料板110和下导料板112之间的间隙移动，拦腰切割热态下的玻璃带，不会产生玻璃粉尘，提高玻璃良品率。通过设置抓取装置5，能够夹住下导料板112下方冷却完毕的玻璃带，辅助切割丝113和横切装置4切割热态下的玻璃带，并且在切割完毕后，抓取装置5能够将其转运。通过设置物性感应器、第二温度传感器和第二调节电极，能够精准控制整个熔融玻璃的温场，控制上导料板110和下导料板112之间的玻璃带温场，从而有利于切割丝113和横切装置4切割热态下的玻璃。
隔板的末端1041向中央倾斜，隔板的末端的纵截面大致呈三角形(前文所述的V型结构)，底部与上导料板110的底部平齐。该三角形设置能够使下拉的熔融玻璃液在隔板的末端1041的底部重新合二为一，有效减小内部应力；通过设置隔板1041的底部与上导料板110的底部平齐，能够提高切割丝113的切割效果。
如图3所示，各个横隔板111的上表面与对应的外板的底部紧贴，横隔板111的下表面与对应的上导料板110的顶部紧贴，能够防止熔融玻璃液泄露；横隔板111的外端与伸缩装置3连接，以驱动横隔板111左右滑动，从而靠近或远离隔板104，以便控制熔融玻璃的流出宽度，进而控制玻璃带的宽度，能够用于生产不用宽度要求的玻璃带；还可以控制横隔板111与隔板104接触，以截断熔融玻璃。
在一种具体的实施方式中，如图4所示，所述伸缩装置3包括第一电机301、第一丝杆302、滑台303和滑座304。其中，滑座304远离成型腔103的一侧设有第一电机301，第一电机301的输出端与第一丝杆302连接；第一丝杆302上设有丝杆螺母(即第一螺母，其固定于滑台303的下方，图中未示出)，丝杆螺母与滑台303的中部固定连接；滑台303的两侧滑动设置在滑座304上；横隔板111设置在滑台303上，以在第一丝杆302的驱动 下随滑台303一起运动。通过设置第一电机301，能够带动第一丝杆302转动；通过设置第一丝杆302和丝杆螺母304，能够推动滑台303在滑座304上直线滑动，将第一丝杆的旋转运动转化为滑台的直线运动，从而带动横隔板111在上导料板110与第一外板101和第二外板102之间滑动，精准控制下拉的熔融玻璃的流量。此外，滑台303与滑座304之间为滑动连接关系，其可以采用多种设置方式实现，例如，滑轨和滑块的方式，轴承运动的方式等等，这是机械领域的技术人员所熟知的。此外，伸缩装置3还可以采用其他能够实现推动横隔板111水平移动的现有的机械或电控产品。
如图5和图6所示，所述横切装置4包括安装板401、第二电机402、平移台403和连接块404；其中，安装板401远离成型腔103的一侧设有第二电机402，安装板401靠近成型腔103的一侧设有主动轮405、从动轮406和滑轨407。主动轮405和从动轮406分别位于安装板401的横向的两端。第二电机402的输出端与主动轮405连接，以驱动主动轮405转动；主动轮405通过传动带408与从动轮406连接。传动带408的上方和下方均设有滑轨407，滑轨407安装在安装板401上，与传动带403的平移方向一致；平移台403的顶部和底部分别通过滑块409与安装板401上的滑轨407配合。平移台403的中部通过连接块404与传动带408连接，以随传动带403运动。平移台403上设有安装块410，切割丝113的端头与安装块410连接，以将切割丝113固定在横切装置4上，随平移台403运动。
通过设置安装板401，能够安装第二电机402、平移台403、主动轮405、从动轮406和滑轨407；本实施方式能够使得第二电机402通过传动带408带动平移台403做往复直线运动，从而带动安装块410和切割丝113做往复直线运动，切割热态下的玻璃；通过设置滑轨407和滑块409，能够保证平移台403运动的稳定性，提高切割质量。
如图6所示，所述横切装置4还可以包括支撑腿411，其设置在安装板401的底部两侧。通过设置支撑腿411，能够稳定地支撑安装板401。此外，所述横切装置4还可以包括多个光电传感器412和遮光板413；其中，光电传感器412设置在安装板401的顶部，可采用槽型光电传感器；遮光板413设置在平移台403上，遮光板413与光电传感器412相配合。通过设置光电传感器412和遮光板413，能够实时监测平移台403的位置，从而判断切割丝113的位置和玻璃的切割进度。
在一实施方式中，两个工作中的光电传感器412之间的距离略大于所需切割的玻璃带的宽度，从而当玻璃带被切割完毕后，可以控制横切装置4停止工作。具体地，各个光电传感器412分别与信号处理器205相连。各个光电传感器412具有相对设置的发光元件4121和受光元件4122，二者之间形成遮光板413能够通过的间隙4123。所述发光元件4121能够发出红外光等可见光；当间隙4123无阻时，受光元件4122能够接收到发光元件4121发出的光，信号处理器205不作判断；当遮光板413运行至间隙4123中时，阻挡了发出的光，受光元件4122无法接收到光，信号处理器205能够获取该信号，从而控制第二电机402开始工作或者停止工作，切割丝113开始切割或停止切割。光电传感器412和遮光板413的工作原理属于电控领域的常规技术方式，是很容易实现的。
如图6中设置了三个光电传感器，左边第一光电传感器为初始端，左边第二光电传感 器和第三光电传感器均为停止端，位于两端的第一光电传感器和第三光电传感器之间的宽度略大于所能切割的玻璃带的最大宽度；中间的第二光电传感器可移动地设置在安装板401上，通过调整与第一光电传感器之间的宽度(此时，第三光电传感器不工作)，从而可以适用于多种不同宽度的玻璃带的切割。当遮光板413到达第一光电传感器时，信号处理器205能够判断平移台403位于初始端，从而控制第二电机402开始工作；当遮光板413到达第二光电传感器或第三光电传感器时，信号处理器205能够判断平移台403位于停止端(切割完成)，从而控制第二电机402停止工作。通过该设置还可以确定切割丝113和平移台403的位置，从而判断二者的位置和切割进度。
如图7和图8所示，所述抓取装置5包括升降装置501、减速电机502和玻璃夹具503；其中，升降装置501的升降台5013上设有减速电机502，减速电机502的输出端设有玻璃夹具503。通过设置升降装置501，能够调整减速电机502和玻璃夹具503的高度位置，从而夹取玻璃，转移玻璃；通过设置减速电机502，能够调整玻璃夹具和玻璃的空间状态，将玻璃由竖直状态调整为水平状态，方便后续转运；通过设置玻璃夹具503，能够稳定夹取玻璃。
在一种具体的实施方式中，如图7所示，所述升降装置501包括第三电机5011以及竖直设置的第二丝杆5012，第三电机5011可为伺服电机，其输出端连接第二丝杆5012以驱动其转动。所述第二丝杆5012上设置有第二螺母(图中未示出)，其至少一侧被限位，从而仅能随第二丝杆5012上下移动。所述升降台5013与第二螺母连接，以随其上下运动。此外，所述升降装置501还可以采用其他能够实现升降的机械或电控装置，例如活塞杆推动等方式，以实现升降台5013的上下移动。
所述升降装置501的升降台5013上设有能够随其上下移动的第四电机504，可为伺服电机，其输出端连接减速电机502的输入端，减速电机502的输出端连接玻璃夹具。减速电机502能够将第四电机504的输出方向进行垂直转换，从而可以控制玻璃夹具503进行翻转，例如由竖直方向转为水平方向。
如图7所示，所述玻璃夹具503包括两个相对设置的用于夹取玻璃带的夹板(即第一夹板5031和第二夹板5032)以及支撑板5033；其中，支撑板5033的第一侧滑动地设置所述的两个夹板5031,5032，支撑板5033的与第一侧相对的第二侧与减速电机502的输出端连接，从而减速电机502能够控制支撑板5033的转动，进而使得夹板带动玻璃带旋转。
为了使得两个夹板5031,5032可滑动地设置于支撑板5033上，在一种具体的实施方式中，如图7和图9所示，所述玻璃夹具503还包括第五电机5034(可选择伺服电机)和主齿轮5035；第五电机5034的输出端连接主齿轮5035，以驱动主齿轮5035转动。所述主齿轮5035还分别啮合有第一从齿轮5036和第二从齿轮5037，以驱动二者转动。两个从齿轮5036，5037可通过销轴等可转动地设置于支撑板5033的第二侧。所述第一夹板5031连接第一齿条5038，第一齿条5038与第一从齿轮5036相互啮合，以驱动第一齿条5038移动，从而带动第一夹板5031滑动；所述第二夹板5032连接第二齿条5039，第二齿条5039与第二从齿轮5037相互啮合，以驱动第二齿条5039移动，从而带动第二夹板5032滑动。两个齿条5038，5039平行设置。进一步地，所述第一从齿轮5036和第二从齿轮5037 分别位于主齿轮5035的相对的两侧，图9中第一从齿轮5036在上侧，第二从齿轮5037在下侧；从而使得两个齿条的运动方向相反，进而促使两个夹板相互靠近或相互远离。例如在图9中，当主齿轮5035顺时针转动时，第一从齿轮5036逆时针转动，带动第一齿条5038和第一夹板5031向左侧运动；此时，第二从齿轮5037逆时针转动，带动第二齿条5039和第二夹板5032向右侧运动；从而使得两个夹板相互远离；反之，当主齿轮5035逆时针转动时，两个夹板相互靠近。
此外，如图7所示，所述支撑板5033的第一侧还设置有两个导轨5040。各个导轨5040的延伸方向与第一齿条5038和第二齿条5039的运动方向平行。两个夹板的背部可通过滑块(图中未示出)分别嵌入这两个导轨5040中，以沿着导轨滑动，从而对夹板的滑动起约束和支撑作用。当两个导轨5040延伸并合并时，也可以看做一个导轨。
通过设置夹板和支撑板5033，能够代替常规的玻璃吸盘，两个夹板5031,5032在支撑板5033上滑动，从两侧稳定夹持玻璃，使用寿命长，不需要定期更换，降低生产成本，提高生产效率。此外，随着机器人技术的发展，本申请中的抓取装置5还可以直接购买或者定做机器手臂，用于实现对成型的玻璃带的抓取工作。
在本实施方式中，如图3所示，所述伸缩装置3具有两个，分别连接两个横隔板111，从相对的两侧对熔融玻璃进行节流。所述横切装置4也具有两个，分别固定切割丝113的两端，将切割丝在图3中的前后方向进行移动，以对初步成型的玻璃带进行切割。如图8所示，所述抓取装置具有两个，能够从两个方向分别抓取同一玻璃带，稳定性更好。此外，值得理解的是，本申请中的各个电机，根据实际的需求，可以选择控制精度较好的伺服电机，也可以选择其他满足需求的电机。
本申请第二种实施方式提供了一种载板玻璃的制造方法，可采用前文任一实施方式所述的载板玻璃制造装置，该制造方法包括：
熔融玻璃进入到第一外板102和第二外板103之间的成型腔内，且通过隔板105将成型腔113内的熔融玻璃分成两部分；
两部分熔融玻璃分别在第一容腔1031和第二容腔1032内且沿着隔板105的侧面同时向玻璃带腔1033方向流动；
从第一容腔1031和第二容腔1032流动到隔板的末端1041的熔融玻璃合二为一并在玻璃带腔1033内向下拉制形成玻璃带。
熔融玻璃分别在所述第一容腔1031和第二容腔1032向下流动过程中，还可以通过所述第一温度感应器201和温控单元202控制熔融玻璃的流动性。
熔融玻璃在所述玻璃带腔1033内流动过程中，还可以通过所述物性感应器和第二温度传感器204感应玻璃带的物理特性，并通过信号反馈给信号处理器205，所述信号处理器205控制各不同区域温控单元对成型腔内熔融玻璃的流动性进行控制。
在一种更具体的实施方式中，所述载板玻璃制造方法，包括以下步骤：
S1、玻璃带成型：控制两个横隔板111与隔板104之间的间距，以便控制玻璃带的宽 度；成型腔103内的熔融玻璃液沿着第一容腔1031和第二容腔1032向下拉制成型，在隔板的末端1041的底部合二为一，然后向下拉制形成玻璃带；玻璃带在两个上导料板110和两个下导料板112之间成型后，继续向下移动，到达抓取装置5的玻璃夹具范围内时，两个伸缩装置3同步控制两个横隔板111水平移动，第一电机301带动第一丝杆302转动，通过丝杆螺母带动滑台303在滑座304上滑动，滑台303带动横隔板111水平移动，从而使两个横隔板111同步朝向隔板104水平移动，截断熔融玻璃；
S2、玻璃带夹取：抓取装置5启动，玻璃夹具503夹住玻璃带，第五电机5034通过齿轮及齿条分别推动两个夹板沿着支撑板5033同步向中间滑动，夹取两个夹板之间的玻璃带；
S3、玻璃带切割：两个横切装置4同步启动，第二电机402带动主动轮405转动，使传动带408在主动轮405和从动轮406之间转动，传动带408通过连接块404带动平移台403在滑轨407上水平移动，使得两个平移台403的安装块410一起带动切割丝113沿着上导料板110和下导料板112之间的间隙切割热态下的玻璃带，将成型后的玻璃带与隔板104上的熔融玻璃分离；
S4、玻璃带转移：升降装置501启动，带动玻璃夹具503向下移动，将玻璃带从两个下导料板112之间带出，第四电机504和减速电机502启动，旋转玻璃夹具503，将竖直状态下的玻璃带旋转至水平状态，方便取下转移，进行二次加工。
所述的实施方式仅仅是对本申请的优选实施方式进行描述，并非对本申请的范围进行限定，在不脱离本申请设计精神的前提下，本领域普通技术人员对本申请的技术方案作出的各种变形和改进，均应落入本申请权利要求书确定的保护范围内。
