请参图8，图8为本申请提供的第二实施例的贴膜设备的气囊载台60a的立体结构示意图。所述实施例中的气囊载台60a与第一实施例中的气囊载台60的不同之处在于：所述气囊载台60a的载气囊板61的上表面设有对应所述工件500形状的一曲面槽611，所述气囊62粘贴于所述曲面槽611内，所述气囊62充气时，能使膜600粘贴的品质更高。
所述电控装置70还包括设于所述工作台10一端的箱体71，设于所述箱体71内的控制器、设于所述箱体71上的若干控制开关73及电性连接于所述控制器的显示屏75。所述控制器用于控制气缸223、上下位移驱动件321、及所有马达。所述显示屏75用于显示贴膜设备100的相关信息、工作状态等。本实施例中，所述定位系统72采用CCD的方式实现自动定位，所述定位系统72设定所述载膜台50上的膜600的中线为第一标线，设定连接于所述定位装置20上的工件500的下表面的中线为第二标线。在将膜600压贴至所述工件500前，所述控制器根据所述定位系统72控制所述左右位移驱动件350及前 后位移驱动件355驱动所述载膜台50移动，至膜600的第一标线正对工件500的第二标线。所述定位系统72设定所述气囊载台60上的气囊62的中心线为第三标线。在将压贴在所述工件500上的膜600进行挤压前，所述控制器根据所述定位系统72控制所述左右位移驱动件370及前后位移驱动件375驱动所述气囊载台60移动，至气囊62的第三标线正对工件500的第二标线。
使用时，操作控制开关73开启贴膜设备100，先将待贴膜的工件500置于两个定位座22之间，控制器控制气缸223驱动三个爪卡2254向内滑动，以卡固所述工件500对应的端部；将膜600放置于所述载膜台50上，所述定位系统72测出所述膜600的中线与所述工件500的下表面中线之间的相对位置，并将数据传输给控制器；所述控制器经过运算后控制所述左右位移驱动件350及前后位移驱动件355驱动所述载膜台50移动，至膜600的第一标线正对工件500的第二标线。所述控制器再控制所述上下位移驱动件321驱动载膜台50向上移动，使所述膜600的中心处压贴至所述工件500的下表面中心处。膜600上表面或工件500的外周面上可预先附着有胶体，当膜600的中部与工件500的底部压贴之后，通过胶体预先定位在一起。所述控制器控制上下位移驱动件321复位，所述左右位移驱动件350及前后位移驱动件355复位，带动所述载膜台50复位；所述定位系统72测出所述气囊62的中心线与所述工件500的下表面中线之间的相对位置，并将数据传输给控制器；所述控制器经过运算后控制所述左右位移驱动件370及前后位移驱动件375驱动所述气囊载台60移动，至气囊62的第三标线正对工件500的第二标线。所述控制器再控制所述上下位移驱动件321驱动气囊载台60向上移动，使所述气囊62包裹所述工件500。对所述气囊62进行充气，所述气囊62挤压所述膜600粘贴于所述工件500上。由于气囊62的充气过程是逐渐进行的，因此施加于工件500上的压力也是逐渐增大，因此可更加可靠地将膜600贴合于工件500上。进一步地，由于气囊62是呈曲面形，因此随着气囊62逐渐充气，工件500的外侧面被逐渐包入气囊62内直至整个外侧面完全包进气囊62中，由此，工件500的整个外表面均有受到气囊62的压力，从而使得膜60被完全贴合于工件500上。所述控制器控制上下位移驱动件321复位、左右位移驱动件370及前后位移驱动件357复位，带动所述气囊载台60复位；最后，控制器控制气缸223驱动三个爪卡2254向外滑动，以解除对工件500的卡固，取出所述工件500 即可。
所述贴膜设备100通过定位系统72能够精准定位膜600与工件500的相对位置，并通过三维移动装置30实现自动化贴膜，不仅提高贴膜的定位精度，而且提高贴膜的效率；采用气囊62挤压所述膜600粘贴于所述工件500上的方式能防止膜被撕扯坏、避免气泡和褶皱产生，提高贴合质量。
请参阅图9，图9为本申请提供的第三实施例的贴膜设备立体分解结构示意图，所述第三实施例与第一实施例的不同之处在于：在第三实施例中，贴膜设备的三维位移驱动装置30a省去一个左右位移驱动件及一个前后位移驱动件。所述三维位移驱动装置30a包括上下位移驱动机构32、一个左右位移驱动件350，以及连接于所述左右位移驱动件350上的一个前后位移驱动件355。所述左右位移驱动件350连接于所述支撑板323上，所述前后位移驱动件355设于所述左右位移驱动件350上。载膜台50及气囊载台60通过一连接板58连接于所述前后位移驱动件355上。在第三实施例中的左右位移驱动件及前后位移驱动件的结构与第一实施例中的左右位移驱动件及前后位移驱动件的结构相同。本实施例中，所述左右位移驱动件350驱动所述前后位移驱动件355、载膜台50及气囊载台60左右移动，所述前后位移驱动件355驱动载膜台50及气囊载台60前后移动，实现自动化贴膜及气囊挤压贴膜，提高贴膜的效率和贴膜的品质。另，所述第三实施例的贴膜设备节省了一个左右位移驱动件及一个前后位移驱动件，节省了制造所述贴膜设备的成本。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
