真空吸塑成型工艺是一种热成型加工方法，其利用热塑性塑料基片制造开口壳体制品，具体方法为：将塑料基片裁切成一定尺寸并加热软化，借助塑料基片上下两侧的气压差或机械压力，使其变形后附贴在特定的模具轮廓上，经过冷却定型，并切边修整成制品。
针对承载液晶玻璃的托盘，该托盘在利用上述的真空吸塑成型工艺制程之后，需要在托盘的内壁人工贴附缓冲材料，以对液晶玻璃进行保护。但是采用人工贴附缓冲材料，作业效率较低且精准度较低。

附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是利用根据本发明的实施例的成型系统成型塑料托盘的流程图；
图2是根据本发明的实施例的成型后的塑料托盘的结构示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。在附图中，为了清楚器件，夸大了层和区域的厚度。相同的标号在整个说明书和附图中可用来表示相同的元件。将理解的是，尽管在这里可使用术语“第一”、“第二”、“第三”等来描述各种元件，但是这些元件不应受这些术语的限制。这些术语仅用于将一个元件与另一个元件区分开来。
图1是利用根据本发明的实施例的成型系统成型塑料托盘的流程图。图2是根据本发明的实施例的成型后的塑料托盘的结构示意图。
参照图1，根据本发明的实施例的成型系统包括：标定装置10、自动化贴附装置20、真空吸塑成型装置30。
以下将以成型图2所示的塑料托盘为例对根据本发明的实施例的成型系统进行详细说明。
通常，塑料基片100在自动化的传送基带上被依次运输到各个加工区域，例如，塑料基片100在自动化的传送基带上被依次运输到标定区域A、贴附区域B、成型区域C。
具体地，首先，当塑料基片100运行至标定区域A时，标定装置10在塑料基片100上标定若干预置区域；其中，所述预置区域指的是将要被贴附缓冲材料的区域。
由图2可知，成型后的塑料托盘200通常用于承载液晶玻璃，其包括分别沿三个不同方向的侧壁的塑料框210，以及设置在每个侧壁上的若干缓冲材料220。但本发明的成型系统成型后的塑料托盘并不以图2所示的塑料托盘200所限，其也可以是包括分别沿两个不同方向的侧壁的塑料框，优选地，这两个 不同方向相互垂直。
这样，在塑料基片100运行至标定区域A之后，标定装置10分别沿第一方向L1，第二方向L2，第三方向L3在塑料基片100上标定四个预置区域11A、11B、11C、11D，三个预置区域12A、12B、12C，三个预置区域13A、13B、13C。应当说明的是，沿任一方向在塑料基片100上标定的预置区域的数量可为任意数量，本发明并不做具体限定。
此外，应当说明的是，第一方向L1垂直于第二方向L2；第三方向L3与第二方向L2平行；沿第一方向L1的四个预置区域11A、11B、11C、11D位于沿第二方向L2的三个预置区域12A、12B、12C和沿第三方向L3的三个预置区域13A、13B、13C。
接着，当被标定了预置区域的塑料基片100运行至贴附区域B时，自动化贴附装置20将缓冲材料自动地贴附在预置区域。
具体地，自动化贴附装置20包括：第一自动化卷筒21、第二自动化卷筒22、第三自动化卷筒23。应当理解的是，利用本发明的成型系统成型后的塑料托盘包括分别沿两个不同方向的侧壁的塑料框时，自动化贴附装置20只包括第一自动化卷筒21和第二自动化卷筒22即可。
第一自动化卷筒21沿第一方向将缓冲材料自动贴附在四个预置区域11A、11B、11C、11D；第二自动化卷筒22沿第二方向将缓冲材料自动贴附在三个预置区域12A、12B、12C；第三自动化卷筒23沿第三方向将缓冲材料自动贴附在三个预置区域13A、13B、13C。在本发明的实施例中，图1中以斜线表示缓冲材料。
最后，当预置区域贴附有缓冲材料的塑料基片100运行至成型区域C时，利用真空吸塑成型装置30将预置区域贴附有缓冲材料的塑料基片100真空吸塑成型为塑料托盘200。这里，真空吸塑成型装置30为现有技术的真空吸塑成型装置，本领域的技术人员可根据现有技术获知真空吸塑成型装置30的具体结构及工作原理，在此不再赘述。
综上所述，根据本发明的实施例的成型系统，利用自动化设备贴附缓冲材 料，提高了作业效率的同时提高了精准度。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
