所述控制机构170还可以控制第二驱动机构160驱动旋转轴直线移动(对应P方向)，从而通过支架110带动所述涂胶部130的涂布头131直线移动，以改变所述涂布头131与所述曲面基板140表面之间的间隙距离Gap。示例性的，所述间隙距离Gap控制在10um～30um范围内；通过将所述间隙距离Gap控制在10um～30um范围内，可以在保证所涂布的涂布胶满足需求的同时不会造成过多的浪费。在涂布过程中，可以通过所述涂布状态检测装置210检测曲面基板140表面的凹凸起伏，进而控制适应性地动态调整所述涂布头131的高度以保持所述涂布头131与所述曲面基板140表面之间的所述间隙距离Gap，从而实现高精度且均匀的对曲面基板140进行涂布。
步骤305、涂布效果监测压力控制，例如通过所述涂布压力机器视觉检测装置200检测实际所需涂布压力，所述控制机构170根据气动伺服装置190返回的推动部133的当前位置信息计算当前涂布压力，根据实际所需涂布压力调整当前涂布压力，以挤出适量的涂布胶。当前一笔涂布与上一笔涂布的截面积对比超过误差上限时输出误差大小到涂胶设备的线调节装置。
步骤306、在没超过误差上限时则进入下一涂布周期，返回上述步骤303继续重复上述步骤已完成整个曲面基板140的涂布。本实施例可以在涂布过程中根据曲面基板140的曲面弧度或者局部突起等调整涂布半径，以高精度且均匀地涂布涂布胶。
进一步的，本示例实施方式中，还提供了一种涂胶设备(图未示)。该涂胶设备可以包括上述任一实施例中所述的曲面涂布装置。
在一种示例性实施例中，所述设备还可以包括进料通道和物料流通通道(图未示)。其中，所述进料通道，用于接收涂布胶。示例性的，所述进料通道可以为位于所述传动件120或支架110上的一通道。所述物料流通通道连接于所述进料通道与所述涂胶部130的储胶腔132之间，用于输送补入所述涂布胶进入所述涂胶部130的储胶腔132内。示例性的，所述物料流通通道的体积大于所述储胶腔132，如所述物料流通通道的截面为矩形或者圆形时，其直径或边长大于所述储胶腔132的直径或边长，这样可以快速补入涂布胶。所述设备还可以包括控制阀(图未示)，设于所述进料通道和所述涂胶部130之间，用于控制涂布胶的输送过程。示例性的，所述控制阀可以是电控阀，如可以设置两个电控阀，一个设置于涂胶部上用于涂胶部130中的储胶腔132的开/闭，一个设置于进料通道口用于进料通道的开/闭。在涂布胶不足时，控制开启进料的阀门，进行涂布胶的补充。补充完在涂布时，开启储胶腔132的阀门，关闭进料的阀门。
该涂胶设备可以根据涂布路径要求，移动改变所述传动件120(即旋转轴)的位置从而改变所述涂布头131的位置，以实现控制涂布路径的曲率。本示例实施方式中所示的上述曲面涂布装置以及涂胶设备具有可调的曲率涂布路径，涂布面位置可控，可以容易地将涂布胶高精度且均匀地涂布于具有翘曲或起伏凹凸的曲面基板上，可以适应多曲率涂布或者单一曲率涂布作业，应用范围广。
本领域技术人员在考虑说明书及实践这里公开的发明后，将容易想到本公开的其它实施方案。本申请旨在涵盖本公开的任何变型、用途或者适应性变化，这些变型、用途或者适应性变化遵循本公开的一般性原理并包括本公开未公开的本技术领域中的公知常识或惯用技术手段。说明书和实施例仅被视为示例性的，本公开的真正范围和精神由所附的权利要求指出。
