在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
此外，在本发明的描述中，除非另有说明，“多个”、“多根”、“多组”的含义是两个或两个以上，“若干个”、“若干根”、“若干组”的含义是一个或一个以上。
如图1、图2、图3和图4所示，本发明实施例提供的框架压缩装置，包括固定组件1和驱动组件2，固定组件1包括第一固定块11和第二固定块12，第一固定块11与第二固定块12相对设置并分别用于 连接固定框架8的两个边框，驱动组件2与第一固定块11和/或第二固定块12连接，以驱动第一固定块11和/或第二固定块12移动，从而压缩框架。
本发明框架压缩装置是一种薄膜9和框架8粘贴用的平台，在薄膜9粘贴前，固定组件1的第一固定块11和第二固定块12能将框架8带胶条81的两边框进行定位，并通过驱动组件2驱动第一固定块11和第二固定块12同时移动或第一固定块11或第二固定块12单独移动，使第一固定块11与第二固定块12作相对彼此靠近的运动，从而压缩框架8未被固定的两边框，使框架8形成一定的凹度后再进行薄膜9粘贴。粘贴完成后，压缩解除，框架8会回复到未压缩的平面状态。框架8从压缩状态恢复到未压缩状态，相当于将薄膜9拉伸，使薄膜9整个面平整，没褶皱，薄膜9处于绷紧状态。本发明利用框架8本身具有一定弹性变形能力的特质，通过对框架8施力使其弯曲，粘贴薄膜9后，在通过框架8自身回复平整的力度来拉伸薄膜9，从而解决原来薄膜9粘贴在框架8上松弛及褶皱问题。
本发明框架压缩装置还包括阻挡组件4，阻挡组件4设置于框架8未被固定的位置处。具体的，在框架8固定完成后，阻挡组件4置于框架上未被固定组件1固定的边框处，以在压缩过程中对框架8施力，防止框架8向要固定薄膜的方向凸起弯曲。阻挡组件4可选用伸缩件，也可选用翻转扣合件。本发明实施例中，阻挡组件可设置于一个边框处，也可对称设置于两个相对的边框上，避免两个边框弯曲方向不同。本实施例中，阻挡组件4包括阻挡片41和阻挡片驱动器42，阻挡片驱动器42的伸缩杆与阻挡片41连接，以控制阻挡片41与框架8接触。本实施例中选用伸缩件作为阻挡组件4，，阻挡组件4设置于框架未被固定的边框的一侧外未，阻挡片驱动器42的伸缩杆与阻挡片41连接，当阻挡片驱动器42的伸缩杆伸缩时，可以带动阻挡片41运动，阻挡片41能够在框架8压缩时，阻挡框架8向上凸起，保证框架8形成下凹状态。本实施例阻挡片驱动器42可选为类似伸缩气缸的元件，设置 于框架8的一侧时，气缸的伸缩杆水平运动，伸出时阻挡片41水平移动至框架8的上表面与其接触，缩回时阻挡片41水平移动离开框架8的上表面；也可设置于框架8的上方，气缸的伸缩杆竖直运动，伸出时阻挡片41竖直下降移动至框架8的上表面与其接触，缩回时阻挡片41竖直上升移动离开框架8的上表面。
进一步的，驱动组件2包括驱动器21和导轨22，导轨22沿框架8的压缩方向设置，第二固定块12设置于导轨22上，驱动器21与第二固定块12连接，以驱动第二固定块12沿导轨向第一固定块11的方向移动。第二固定块12的底部通过螺栓与滑块连接，滑块设置于导轨22上，并沿导轨22直线滑动，从而实现第二固定块12的运动。驱动器21可选用气缸推动或丝杠螺母等能够实现直线往复驱动元件。在本发明的其他实施例中，也可以在第一固定块11和第二固定块12下均安装导轨22，驱动器21可分别或同时控制与第一固定块11和第二固定块12，推动第一固定块11与第二固定块12彼此相向移动。
其中，本实施例选择的驱动器21为压缩气缸，其位于第一固定块11与第二固定块12之间连接第二固定块12。本实施例中，在框架8放置前，装置的驱动器21的伸缩杆处于伸出状态，阻挡片驱动器42处于缩回状态。
本发明框架压缩装置还包括缓冲器5，缓冲器5设置于第一固定块11与第二固定块12之间，且对第二固定块12施加与框架8的压缩方向反向的缓冲力。缓冲器5能够在第一固定块11和第二固定块12作相向运动时起到缓冲作用，保证第二固定块12缓速平稳移动，避免驱动器21的瞬时驱动导致框架8的负载过大而断裂损坏。在本发明的其他实施例中，也可以在第一固定块11和第二固定块12处均安装缓冲器5，可分别或同时控制与第一固定块11和第二固定块12的靠近移动速度。
本发明框架压缩装置还包括安装板6，驱动组件2和阻挡片驱动器42均固定于安装板6上，缓冲器5通过连接件61固定于安装板6上。 导轨22与安装板6通过螺栓连接固定，驱动器21和导轨22与安装板6均通过螺栓连接固定，缓冲器5外部套设连接件61，连接件61与安装板6螺栓连接固定，阻挡片驱动器42与安装板6螺栓连接固定，螺栓连接便于拆卸。
其中，第一固定块11和第二固定块12上均设有真空吸附孔3，且分别吸附框架8的两边框的下表面。框架8可通过粘贴、压紧、吸附等方式固定于第一固定块11和第二固定块12上，本实施例由于框架8带胶条81表面向上设置，方便薄膜9直接送至框架8上方进行粘贴，压紧形式不便于粘贴，所以选择吸附方式，第一固定块11和第二固定块12具有一定数量的真空吸附孔3，用于在竖直方向上提供真空吸附力吸附框架8带胶条81边框的底面。
本发明框架压缩装置还包括真空发生装置，真空发生装置通过真空吸附孔3将框架8固定于第一固定块11和第二固定块12上。第一固定块11与第二固定块12产生的真空吸附力均是通过真空发生器实现的。
其中，第一固定块11和第二固定块12各设有两个定位柱7，两个定位柱7之间的距离为其固定的框架8的边框的长度。第一固定块11和第二固定块12上分别有两个定位柱7，能够对框架8的两边进行定位。
本发明框架压缩装置还包括控制元件，控制元件包括传感器和控制器，传感器用于检测框架8的压缩程度并将检测信号传给控制器，控制器与驱动组件2连接，根据检测信号控制驱动组件2驱动第一固定块11和/或第二固定块12的移动距离。控制器获取传感器检测到的框架8压缩信息，从而控制驱动组件2的启停动作，保证框架8压缩程度一致，防止框架8因压缩过度而断裂损毁。
本发明实施例还提供了应用上述框架压缩装置进行薄膜拉伸方法，包括如下步骤：
S1，将框架8的两个边框分别固定于相对设置的第一固定块11和 第二固定块12上，并；
S2，启动驱动组件2，驱动第二固定块12和第一固定块11相向移动，或驱动第二固定块12沿靠近第一固定块11的方向移动，以使框架8弯曲；
S3，将薄膜9送至框架8上方并将其与框架8固定的两个边框粘贴；
S4，启动驱动组件2，驱动第二固定块12和第一固定块11相背移动，或驱动第二固定块12沿远离第一固定块11的方向移动，至框架8恢复到水平状态。
本发明薄膜拉伸方法是一种薄膜和框架拉伸用的方法，在薄膜9粘贴前，先通过第一固定块11和第二固定块12将框架8带胶条81的两边框进行定位，再通过驱动组件2驱动第一固定块11和第二固定块12共同或第一固定块11或第二固定块12单独移动，使第一固定块11与第二固定块12作相对彼此靠近的运动，从而压缩框架8未带胶条81的两边框，使框架8形成一定的凹度后再进行薄膜9粘贴。粘贴完成后，压缩解除，框架8会回复到未压缩的平面状态。框架8从压缩状态恢复到未压缩状态，相当于将薄膜9的两边拉伸，使薄膜9整个面平整，没褶皱，薄膜9处于绷紧状态。本发明利用框架8本身具有一定弹性变形能力的特质，通过对框架8施力使其弯曲，粘贴薄膜9后，在通过框架8自身回复平整的力度来拉伸薄膜9，从而解决原来薄膜9粘贴在框架上松弛及褶皱问题。
其中，为保证框架8在压缩过程中向下形变弯曲，而不向上凸起，在步骤S1与步骤S2之间还包括以下步骤：
S121，启动阻挡组件4，阻挡框架8向上凸起，以使框架8在压缩过程中形成下凹状态；
为保证在框架8下凹弯曲后，薄膜9在粘贴前框架8处无障碍物，便于与框架8粘贴，在步骤S2与步骤S3之间还包括以下步骤：
S231，启动阻挡组件4，使阻挡组件4远离框架8。
综上所述，本发明框架压缩装置及薄膜粘贴方法是一种薄膜和框架粘贴用的平台及方法，在薄膜粘贴前，固定组件的第一固定块和第二固定块能将框架带胶条的两边框进行定位，并通过驱动组件驱动第一固定块和第二固定块共同或第一固定块或第二固定块单独移动，使第一固定块与第二固定块作相对彼此靠近的运动，从而压缩框架未带胶条的两边框，使框架形成一定的凹度后再进行薄膜粘贴。粘贴完成后，压缩解除，框架会回复到未压缩的平面状态。框架从压缩状态恢复到未压缩状态，相当于将薄膜的两边拉伸，使薄膜整个面平整，没褶皱，薄膜处于绷紧状态。本发明利用框架本身具有一定弹性变形能力的特质，通过对框架施力使其弯曲，粘贴薄膜后，在通过框架自身回复平整的力度来拉伸薄膜，从而解决原来薄膜粘贴在框架上松弛及褶皱问题。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。
