Description

对板件或圆盘进行涂漆或涂膜的装置
本发明涉及一种借助于一个缩窄成呈毛细作用的敞口的槽来对板件或圆盘、特别是液晶显示器制造中的玻璃板、进行涂漆或涂膜的装置。
在薄涂层技术领域中、特别在制造液晶显示屏、制造用于半导体生产、半导体基片或陶瓷基片等等的掩膜时，常常碰到这样的任务：在矩形的或圆形的板件上设置一层均匀的漆或其它诸如滤色剂或者特殊保护层的起先是液态的介质。PCT/DE93/00392公开了一种改进这种涂漆与涂布过程的装置。使用这样装置可改善特别是矩形板件上的漆层厚度的均匀性，同时还可减少漆的消耗量。此外，在涂布时毋须转动待涂布的板件，从而也节约了为此而设的机械费用。
本发明的目的在于根据上述准则对PCT/DE/00392描述的类型的、用于对板件进行涂漆与涂布的装置作进一步的改进并同时将结构简化。
实现本发明的目的的技术解决方案在于，装置具有毛细间隙，间隙充装有液态涂布介质，板件在跟间隙成很小的间距的情况下以其待涂漆或涂布的表面朝下缓慢地通过间隙，通过毛细作用与粘附作用在板件上积附一层薄的涂层。板件以其待涂漆的面朝下被导引通过槽，该槽设计成起毛细作用并从而使漆自动地并以特别均匀的速度供应。毛细作用是通过构成一个宽度小于0.5毫米的狭窄间隙来达致的。通过毛细作用，漆或其它涂布液克服了重力作用自动地以恒定速度向上升高并突出毛细间隙的上端。在间隙上方，漆流成窄线接触到待涂布的板件表面并积附在其上形成漆层。
通过两块垂直设置的、相互平行的薄板浸入充装在敞口的槽内的涂布液中并且其间间距可以无级地调节来产生毛细作用是有利的。这样，在两块板之间就能够在槽的整个长度上形成一个具有最适合产生毛细作用的宽度的间隙。因此毛细间隙的几何形状可与各种不同类型的待涂布的板件配合。
待涂漆或待涂布的板件以跟间隙的上端相距一个很小的距离、例如小于0.2毫米的距离以均匀和缓慢的速度通过间隙的上端被证明是特别有利的。这样，漆就会紧接在从毛细间隙的上端出来后接触上板件表面。漆通过粘附作用牢固地保持在板件表面上并跟板件一起离开间隙的上端。这就使由于毛细作用随着向上运动的后继的漆从间隙抽出并且根据板件的运动速度来以限定的漆层厚度积附在板件上。此外，通过漆对板件表面的粘附作用，不存在漆在离开间隙后向侧面流动从而被坏漆层厚度均匀性的危险。
两板之间的间隙在每次涂漆过程后扩宽到2毫米至3毫米的宽度是特别有利的。这样就阻止了漆在涂漆过程以外的时间里有不希望有的自动升高(毛细作用)。经已证明，漆较长时间留在毛细间隙里会使其性能发生变化，对涂漆的效果起环的作用。如果把间隙扩宽到2毫米至3毫米，留在间隙内的漆的性能就会保持不变。
将两块板之间的间隙在紧接涂漆过程开始之前缩窄至毛细宽度是有利的。这样，处在两块板之间的漆首先自动地向上移动，直至突出间隙上端并与已就位的待涂布的板件表面接触。因此涂漆过程就通过如前所述的在此时已形成毛细间隙内的毛细作用、板件的运动和粘附作用来实现。
本发明的另一有利的结构在于，不再需要将待涂漆的板件接对角线方向并向上翘起一个小角度来向涂漆槽导引。此外，也不需要在槽(间隙)上方形成弯月形液面，这样也就可以不用通过一个补偿容器来进行漆的补给。
为使本发明的装置全自动化运转，可分别在进料和卸料端放置自动上料装置和自动卸料装置。本发明的装置也可以设置成使板件夹持装置固定不动，而使涂布槽成为活动部份。
通过下面描述的和附图中所示的实施例阐明本发明的细节和其它有利的结构，但这些实施例绝不能理解成对本发明的限制。在附图中，
图1是本发明的涂漆与涂膜装置的结构的前视图；
图2是在涂布过程开始时通过图1所示的具有毛细间隙的槽的横截面图。
图1示出了本发明的涂膜装置10的第一个实施例。槽12和直线输送装置15的支柱13、14均固定在机座11上。直线输送装置15的运动部份面朝下。为待涂漆板件17而设的可转动的夹持装置16固定在上述运动部份上。该板件17例如是一块待涂漆的玻璃板，涂漆后用以制作掩模或液晶显示屏。板件17例如通过真空固定吸附在夹持装置16上。为此，夹持装置16上具有相应的、图中未示出的真空孔。在本发明的范畴内也可应用其它的、专业人员熟悉的夹持装置。
槽12以横截面形式示出在图1中，并以放大比例示出在图2中。槽12中的空腔16部份地充装有漆料，有两块薄板19和20从上面浸入漆液中。板19在33处跟槽12的上缘固定地连接，因而板19是不能动的。而板20则通过一个合适的装置跟一个直线运动装置22相连，通过该装置可沿在图2中以标号23标示的箭头方向往复运动。因此，在板19与20之间的宽度可以无级调节。
为了取得最佳的涂漆或涂布效果，所用的涂布液必须具有规定的温度并且必须很洁净。因此所用的涂布液从贮液箱28往槽12输送时须经过一个温度控制装置29和一个过滤器30。涂布液输送也可以通过在贮液箱中产生超压(气垫)来实现，或通过适当地布置贮液箱的位置、使涂布液通过高度差向槽输送。还有可能使用专业人员公知的其它输送液体手段。
在一个全自动化型式的涂布装置中，在标号31所标示的部位装有一个自动上料装置，并在标号32所标示的部位装有一个自动卸料装置。上料装置31从设在一个确定的地点的料库中取出待涂漆的板件17，并把它导往夹持装置16。卸料装置从夹持装置16接过板件17，并把它运送到设在另一个确定的地点的另一个料库中。
涂漆和涂膜装置的工作方式
首先将板件17自动地或手动地固定在夹持装置16上。还可以通过转动夹持装置16来对该位置进行修正。夹持装置此时处于图1中以标号31标示的位置附近。在板件17在正确的位置固定在夹持装置16上之后，直线输送装置15沿标号26标示的箭头方向、即朝槽12的方向运动。
板件17从侧面被导引到间隙24的上缘。一当板件17的前缘25到达间隙24的正上方，在槽12中的板20即朝向板19移动，直至在两块板之间形成合适的毛细间隙宽度为止。由于间隙变窄，小量的液体突出间隙24压到板件17的待涂布的表面的前缘上，从此开始了涂布过程。此时，板件17通过直线输送装置15沿着箭头26的方向以均匀的速度往前移动，与此同时，一层薄的液体层通过粘附作用积附在板件表面上。所需的液流通过间隙24内的毛细作用得到补给。
一当板件17的后缘27越过了间隙24，涂布过程就终结。然后，基于前面所述的原因，在下一个涂布过程开始之前，两块板19与20之间的间距拉开到2至3毫米。板件17继续向前移动到标号32所示的位置，在该位置上被自动地或手动地从夹持装置16取下。
