具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
通常的涂布设备可包括应对三种不同涂布工艺分别设计的三个涂布单元， 分别是正面涂布单元、背面涂布单元、侧边密封涂布(Side Sealing)单元，各个单元分别使用1～2个涂布器以分别进行正面涂布、背面涂布、侧边密封等涂布工艺。在研究中，本申请的设计人发现：在生产阵列基板行驱动(GOA)产品时，因为阵列基板行驱动产品除了需要进行正面涂布和背面涂布工艺之外还需要进行侧边密封工艺，所以涂布设备需要设置三个涂布单元；如果产线配置三个涂布单元，即正面涂布单元、背面涂布单元、侧边密封单元，在生产常规产品时，因为常规产品只需要进行正面涂布和背面涂布工艺，所以正面涂布单元和背面涂布单元被使用，而侧边密封涂布单元被闲置，从而导致涂布设备利用率低，增加不必要能源及材料损耗；如果产线只配置两个单元，例如只有正面涂布单元和背面涂布单元，那么在产线转型、生产阵列基板行驱动产品时，因为需要进行侧边密封工艺，产线无法对应，从而造成其他损失。另一方面，由于常规产品通常需要涂覆三个键合边，各个单元需要分别使用多个涂布器来进行涂布，然而阵列基板行驱动(GOA)产品通常只需要涂覆一个键合边，在生产阵列基板行驱动(GOA)产品时，涂布设备上用于生产常规产品的涂布器会有闲置，从而也导致涂布设备利用率低，增加不必要能源及材料损耗。另外，如果涂布单元或涂布器长时间不使用，固化胶(例如，紫外固化胶)会在管路中凝固，从而影响设备寿命及后续涂布效果，所以每次长时间停止，重新启用涂布单元或涂布器时需要进行排胶、重新调整涂布参数等工作，影响稼动率。
本公开的实施例提供一种涂布设备，其包括可沿第一方向运动并进行涂布的涂布器，涂布器包括涂覆头以及涂覆头移动机构，所述涂覆头移动机构被配置为使所述涂覆头在与所述第一方向相交的平面内运动并使所述涂覆头在与所述第一方向相交的平面内转动。该涂布设备是一种可切换一体化设备，可利用一个涂布器应对正面涂布、背面涂布以及侧边密封三种不同工艺，从而可节省设备成本，提高设备利用率。
下面结合附图对本公开实施例提供的涂布设备进行详细的描述。
实施例一
本实施例提供一种涂布设备，如图1所示，该涂布设备包括涂布器300，可用于为沿第一方向进行涂布。如图2a所示，涂布器300包括涂覆头310以及涂覆头移动机构320，涂覆头移动机构320可使涂覆头310在与第一方向相交的平面内运动并使涂覆头310在与第一方向相交的平面内转动，也就是说，涂覆头移动机构320可用于使涂覆头310的涂覆端311沿在与第一方向相交的 平面内的弧线运动。需要说明的是，第一方向为图2a中沿纸面的水平方向，当然，本公开包括但不限于此，第一方向不限于图2a中所示，可根据实际需求进行设置。
在本实施例提供的涂布设备中，通过设置包括涂覆头以及涂覆头移动机构的涂布器，可使涂覆头在与第一方向相交的平面内运动并在与第一方向相交的平面内转动。由此，该涂布器可通过涂覆头移动机构来调整涂覆头的位置以及角度，从而可单独实现正面涂布工艺、背面涂布工艺以及侧边密封工艺。也就是说，本实施例提供的涂布设备可只设置一个涂布器就可同时实现正面涂布工艺、背面涂布工艺以及侧边密封工艺，从而可使采用本实施例提供的涂布设备的产线可应对常规产品以及阵列基板行驱动(GOA)产品等不同产品，并且不会造成涂布器闲置以及涂布设备利用率低等问题，进而可避免不必要能源及材料损耗。另外，当采用本实施例提供的涂布设备的产线转型生产不同类型的产品时，只需对涂布器的工作方式进行调整，无需重新进行排胶、调整涂布参数等工作，可提高稼动率。
例如，在本实施例一示例提供的涂布设备中，如图1所示，该涂布设备还包括：搬运机构100和涂布平台200。搬运机构100用于搬运待涂覆物体；涂布平台200用于承载所述待涂覆物体(例如，待涂覆的液晶显示面板)，第一方向平行于涂布平台所在的平面。由此，该涂布设备可通过搬运机构搬运待涂覆物体，可通过涂布平台承载待涂覆物体，并且可在涂布平台上承载的待涂覆物体上进行涂覆。
例如，在本实施例一示例提供的涂布设备中，如图2a所示，涂覆头移动机构可使涂覆头沿垂直于涂布平台的第二方向运动并使涂覆头在垂直于第一方向的平面内转动。需要说明的是，第一方向为图2a中沿纸面的水平方向，第二方向为图2a中沿纸面的竖直方向，当然，本公开包括但不限于此，第一方向和第二方向不限于图中所示，可根据实际需求进行设置。
例如，当本公开的实施例提供的涂布设备用于正面涂布工艺时，如图5a所示，通过涂覆头移动机构将涂覆头310移动到涂布平台200上方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，使得涂覆头310处于向下的位置，从而在待涂覆物体900的待涂覆的位置进行正面涂布工艺。
例如，待涂覆物体900为液晶显示面板，如图5a所示，该液晶显示面板 包括依次设置在涂布平台200上的阵列基板偏光片901、阵列基板902、对置基板903和对置基板偏光片904以及设置在阵列基板902一侧边缘上的覆晶薄膜905。阵列基板902具有用于进行显示的显示区和位于显示区外围的连接区(Fan Out)，显示区中引线的端头位于连接区中；覆晶薄膜905设有引线或电极，覆晶薄膜905用于通过这些引线或电极和阵列基板902的连接区的端头相连并键合。通过涂覆头移动机构将涂覆头310移动到涂布平台200上方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，也就是说，涂覆端311沿在垂直于第一方向的平面内的弧线转动，从而使涂覆头310在覆晶薄膜905远离阵列基板902的一侧靠近对置基板903的位置涂覆液态光固化胶，以防止键合后的引线或电极裸露在空气中以避免电极被腐蚀并且还可防止漏光现象的发生。
例如，当本公开的实施例提供的涂布设备用于背面涂布工艺时，如图5b所示，通过涂覆头移动机构将涂覆头310移动到涂布平台200下方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，使得涂覆头310处于向上的位置，从而在待涂覆物体900的待涂覆的位置进行背面涂布工艺。
例如，待涂覆物体900为上述的液晶显示面板，如图5b所示，通过涂覆头移动机构将涂覆头310移动到涂布平台200下方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，从而使涂覆头310在覆晶薄膜905靠近阵列基板902的一侧靠近阵列基板902的位置涂覆液态光固化胶，以防止键合后的引线或电极裸露在空气中以避免电极被腐蚀并且还可防止漏光现象的发生。
例如，当本公开的实施例提供的涂布设备用于侧边涂布工艺时，如图5c所示，通过涂覆头移动机构将涂覆头310移动到涂布平台200上方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，使得涂覆头310与待涂覆物体900齐平，从而在待涂覆物体900的待涂覆的位置进行侧边密封工艺。
例如，待涂覆物体900为上述的液晶显示面板，如图5c所示，通过涂覆头移动机构将涂覆头310移动到涂布平台200上方，并通过涂覆头移动机构通过在垂直于第一方向的平面内转动来调整涂覆头310的旋转角度，从而使涂覆头310与阵列基板902和对置基板903之间的缝隙齐平，也就是说，使得涂覆 头310与阵列基板902和对置基板903之间的缝隙处于同一水平面上，从而使得涂覆头310在阵列基板902和对置基板903之间的缝隙涂覆液态光固化胶以进行侧边密封工艺。
需要说明的是，上述的待涂覆物体为液晶显示面板，然而本公开包括但不限于此，待涂覆物体可为其他物体，例如，有机发光二极管显示面板。
实施例二
在实施例一的基础上，本实施例提供一种涂布设备，如图1所示，该涂布设备包括：搬运机构100、涂布平台200和涂布器300。涂布平台200和涂布器300可设置在同一平面上，搬运机构100可设置在高于涂布平台200和涂布器300所设置的平面上的平面上。当然，本实施例包括但不限于此。
例如，在本实施例一示例提供的涂布设备中，如图2a所示，该涂布设备还包括第一推进机构400。第一推进机构400包括第一导轨410，第一导轨410沿第一方向延伸，涂布器300设置在第一导轨410上，第一推进机构400被配置为使涂布器300沿第一方向运动。例如，第一推进机构400还包括滚轮420以及驱动滚轮420的电机(图中未示出)，滚轮420可设置在第一导轨410上并与涂布器300相连，由此第一推进机构400可通过电机驱动滚轮420以在第一导轨410上沿第一方向进行运动，从而可使涂布器300在第一方向上进行涂布。
需要说明的是，本实施例以第一推进机构400包括第一导轨410为例进行说明，但不限于此。例如，第一推进机构可以包括第一方向丝杠，以使涂布器进行精确的移动。或者，第一推进机构也可以包括平移气缸。
例如，在本实施例一示例提供的涂布设备中，如图2a所示，涂覆头移动机构320包括：第二推进机构500和旋转结构600；第二推进机构500可使涂覆头310沿第二方向运动；以及旋转结构600，可使涂覆头310在垂直于第一方向的平面内转动。由此，涂覆头移动机构320分别通过第二推进机构500和旋转结构600来实现使涂覆头310沿垂直于涂布平台200的第二方向运动和在垂直于第一方向的平面内转动。另外，本实施例提供的涂布设备结构较为简单、可靠。
例如，在本实施例一示例提供的涂布设备中，如图2b所示，搬运机构100包括第一子搬运机构101和第二子搬运机构102，第一子搬运机构101用于将待涂覆物体移动到涂覆平台200，第二子搬运机构102用于将完成涂覆的待涂 覆物体移出涂覆平台200。由此，通过设置两个子搬运机构(即，第一子搬运机构101和第二搬运机构102)可以在对多个待涂覆物体进行涂覆时，能够实现移入与移出动作同时进行，实现快速的搬运，从而减少节拍时间。需要说明的是本实施例以设置两个子搬运机构为例进行说明，但不限于此，还可以是一个或多个。另外，由于涂布器300和涂布平台200设置在同一水平面上，这里为了清楚标示涂布器300和涂布平台200，采用图2a和图2b分别示出涂布设备的正面示意图。
例如，在本实施例一示例提供的涂布设备中，搬运机构100可为沿第一方向以及第二方向运动。由此，搬运机构可通过沿第一方向运动将待涂覆物体从涂布设备外搬运到涂布设备中或者将待涂覆物体从涂布设备中搬运到涂布设备外，并通过沿第二方向运动将待涂覆物体从搬运机构上放置到涂布平台上或者从涂布平台上抓起待涂覆物体。
例如，在本实施例一示例提供的涂布设备中，如图2b所示，搬运机构100还包括抓取头130，抓取头130上固定有吸盘或夹爪，用于吸住或夹住待涂覆物体。
例如，在本实施例一实施例提供的涂布设备中，如图2b所示，搬运机构100还包括：第一搬运导轨110和第二搬运导轨120；第一搬运导轨110，沿第一方向延伸，搬运机构100被配置为通过第一搬运导轨110沿第一方向运动；第二搬运导轨120，沿第二方向延伸，搬运机构100被配置为通过第二搬运导轨120沿第二方向运动。当然，本公开包括但不限于此，搬运机构还可为机械臂，从而将待涂覆物体移动到涂覆平台或将完成涂覆的待涂覆物体移出涂覆平台。
需要说明的是，如图2b所示，当搬运机构包括两个子搬运机构(例如，第一子搬运机构101和第二子搬运机构102)时，两个子搬运机构可共用第一搬运导轨110。
例如，在本实施例一实施例提供的涂布设备中，如图2b所示，涂布平台200被配置为沿第一方向和垂直于第一方向和第二方向的第三方向运动并且在垂直于第二方向的平面内转动。图2b中第三方向是指垂直于纸面的方向，即第三方向垂直于第一方向和第二方向。
例如，在本实施例一实施例提供的涂布设备中，如图1和2b所示，涂布平台200包括：第一涂布导轨210、第二涂布导轨220和旋转部230。第一涂 布导轨210，沿第一方向延伸，涂布平台200可通过第一涂布导轨210沿第一方向运动；第二涂布导轨220，沿第三方向延伸，涂布平台200可通过第二涂布导轨220沿第二方向运动；旋转部230可使涂布平台200在垂直于第二方向的平面内转动。涂布平台200通过在第一涂布导轨210和第二涂布导轨220上的运动，可以到达搬运机构100所在位置处接收待涂覆物体；待涂覆物体被涂覆完毕后，涂布平台200再次通过在第一涂布导轨210和第二涂布导轨220上的运动，到达搬运机构100所在位置处，将已完成涂覆的待涂覆物体移交给搬运机构100。旋转部230使涂布平台200在垂直于第二方向的平面内转动，例如，涂布平台200在垂直于第二方向的平面内的转动角度为0°-360°，因而可以使涂布器300对待涂覆物体不同边进行涂覆。
例如，如图5a-5c所示，当涂覆头310完成待涂覆物体900一边的正面涂布工艺和背面涂布工艺后，可通过涂布平台200在在垂直于第二方向的平面内转动将待涂覆物体900进行旋转，使待涂覆物体900其他待涂覆的边旋转到靠近涂覆头310的一侧，从而可以使涂布器300对待涂覆物体不同边进行涂覆。
例如，本实施例一实施例提供的涂布设备还包括：对位机构，用于使设置在涂布平台上的待涂覆物体与涂布器对准。
实施例三
在实施例一的基础上，本实施例提供一种涂布设备，如图3所示，用于使涂覆头310在垂直于第一方向的平面内转动的旋转结构600可包括：驱动电机610、涂覆头转轴620以及传送带630。驱动电极610包括输出轴611，输出轴611可在绕平行于第一方向的轴向转动；涂覆头转轴620与涂覆头310固定相连，涂覆头310可随着涂覆头转轴620的转动而转动，并且涂覆头转轴620的轴向为第一方向；传动带630连接输出轴611与涂覆头转轴620。由此，当驱动电极610的输出轴611在垂直于第一方向的平面内转动时，可通过传动带630驱动涂覆头转轴620在垂直于第一方向的平面内转动，进而驱动涂覆头310在垂直于第一方向的平面内转动。
例如，在本实施例一示例提供的涂布设备中，旋转结构600还包括：固定部640，输出轴611和涂覆头转轴620设置在固定部640的两端以使输出轴611与涂覆头转轴620的相对位置固定，从而使涂覆头310能够精确、稳定地在垂直于第一方向的平面内转动，从而保证涂布的精准度。
需要说明的是，本公开提供的旋转结构包括但不限于此，旋转结构还可采 用其他结构，例如，在涂覆头内部设置转轴和驱动电机。
例如，在本实施例一示例提供的涂布设备中，如图4所示，涂布器300还包括固化灯700，固化灯700与涂覆头310在第一方向上依次设置，固化灯700用于固化涂覆头310涂覆的液态固化胶。由此，当涂覆头310用于涂覆液态光固化胶(例如，紫外光固化胶)时，与涂覆头310依次设置的固化灯700可快速地将涂覆的液态光固化胶固化，防止液态光固化胶流动造成的不良。
例如，固化灯700与涂覆头转轴620固定相连，输出轴611通过传动带630和涂覆头转轴620带动固化灯700在与第一方向垂直的平面内转动，也即沿垂直于第一方向的平面内的弧线运动。固化灯700可以随着涂布器300进行涂布动作的同时对液态固化胶进行固化。
例如，固化灯700也可以不随涂覆头转轴620在垂直于第一方向的平面内转动。
例如，固化灯700可以为紫外光固化灯。
例如，固化灯700的光源可以为激光发射器，固化灯700可发出平行光源。
例如，固化灯700还可以与涂覆头310一体化形成，形成在涂覆头310内部。
例如，液态固化胶可以是液态光学胶、光刻胶等。

例如，背面涂布工艺操作包括：搬运机构沿第一方向和第二方向运动，将待涂覆物体搬运至预定位置；涂布平台沿第一方向和第三方向运动，移动到搬运机构所在的预定位置下方，接收待涂覆物体，此时，搬运机构可通过沿第二方向运动将待涂覆物体放置在涂布平台上；搬运机构沿第一方向和第二方向运动回到初始位置；涂布平台沿第一方向和第三方向运动，并在对位机构的帮助下到达涂布位置，等待涂布器完成涂胶动作；通过涂布器沿第二方向运动，调整其高度以及旋转角度，使涂覆头移动到涂布平台下方，并且处于向上的位置(如图5b所示)，从而在待涂覆物体的待涂覆的位置进行背面涂布工艺对待涂覆物体完成涂布；涂布器完成涂胶动作后，涂布平台沿第一方向和第三方向进行运动，将已完成涂覆的待涂覆物体运送到移出位置，等待搬运机构接取；搬运机构沿第一方向和第二方向运动到移出位置，将已完成涂覆的待涂覆物体移出。
例如，侧边密封工艺操作包括：搬运机构沿第一方向和第二方向运动，将待涂覆物体搬运至预定位置；涂布平台沿第一方向和第三方向运动，移动到搬运机构所在的预定位置下方，接收待涂覆物体，此时，搬运机构可通过沿第二方向运动将待涂覆物体放置在涂布平台上；搬运机构沿第一方向和第二方向运动回到初始位置；涂布平台沿第一方向和第三方向运动，并在对位机构的帮助下到达涂布位置，等待涂布器完成涂胶动作；通过涂布器沿第二方向运动，调整其高度以及旋转角度，使涂覆头移动到涂布平台上方，并且处于与待涂覆物体侧边上的待涂覆位置齐平的位置(如图5c所示)，从而在待涂覆物体的待涂覆的位置进行侧边密封工艺对待涂覆物体完成涂布；涂布器完成涂胶动作后，涂布平台沿第一方向和第三方向进行运动，将已完成涂覆的待涂覆物体运送到移出位置，等待搬运机构接取；搬运机构沿第一方向和第二方向运动到移出位置，将已完成涂覆的待涂覆物体移出。
需要说明的是，上述的正面涂布工艺操作、背面涂布工艺操作和侧边密封工艺操作也可对同一待涂覆物体进行，此时只需将待涂覆物体通过搬运机构搬运至预定位置，通过涂布平台移动到涂布位置，然后通过调整涂布器的高度和旋转角度分别进行正面涂布工艺操作、背面涂布工艺操作和侧边密封工艺操作(不分先后次序)；最后再通过搬运机构将已完成涂覆的待涂覆物体移出。
有以下几点需要说明：
(1)除非另作定义，本公开实施例以及附图中，同一标号代表同一含义。
(2)本公开实施例附图中，只涉及到与本公开实施例涉及到的结构，其他结构可参考通常设计。
(3)为了清晰起见，在用于描述本公开的实施例的附图中，层或区域的厚度被放大。可以理解，当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时，该元件可以“直接”位于另一元件“上”或“下”，或者可以存在中间元件。
