Abstract

用于尤其是通过加热处理将装配/模制在一起的塑料物品的表面(8)的方法和装置，塑料物品事先在该同一模具中被模制或被放置在其中，该装置具有至少一个可转动模具部分(1)。热量/能量的供给是以一个或多个激光束(9)或其它类型的精确加热方式进行，并且在随后的材料被增加/模制之前被导向先前模制的相互交界表面(8)中的至少一个上。表面(8)也可以通过处理在选定区域变形，从而增大粘附力。本发明还意味着可以获得适合于制造某些物品的具有好的、差的或没有粘附力的区域。

Description

用于处理被模制和装配的表面的方法和装置
技术领域
本发明涉及用于通过对塑料物品的将要组装起来的表面供给能量来处理模制在一起的表面的方法和装置。
背景技术
从PCT申请PCT/DK01/00699可以了解在一个装置中利用至少一个可转动模具部件装配优选由塑料制成的中空物品，例如两个球壳，装配在是中空物品被模制的连接处进行的。从该专利申请还可以了解，还可以在装配过程中将相互接触的物品两侧施加热量。但在该专利申请中没有公开如何实现供热。尽管有相当大的热传递，由于组件没有变得足够坚固，在尝试装配几种材料的组合例如均匀的聚烯烃尤其是化学特性不同的聚乙烯和聚苯乙烯时具有相当大的缺陷。此外，也显示在热传递同时还具有严重缺点，即热量也非常容易导致将要装配的两个区域以及周围区域变形。
发明内容
本发明的方法和装置就是为了在涉及均匀以及化学特性不同的材料时消除这些缺点，同时不会丧失在同一装置中装配两个刚模制/一起模制的物品时根据上述专利申请可以获得的优点。
这可以通过从合适类型的激光器发出的引导激光束形式或其它类型的集中辐射施加必要的热量/能量来实现。通过这种辐射，可以获得组合的优点，因为激光束可以被编程以仅仅影响将被装配的区域的精确的特定部分，而该表面的其它部分、其外轮廓和外表保持未触动。此外，也可以在意欲结合的有限区域获得激光束，以便在将装配的表面上产生刻痕或其它类型的凹槽和/或切口，这使得装配更加容易和更牢固，因为这样可获得补充机械附着力。
根据本发明的装置的特征在于，所述装置包括一或多个以精确加热方式供给热量/能量的激光束，热量/能量在物品即将完成之前被导向先前模制的相互交界表面中的至少一个。
根据本发明的方法，其特征在于，热量/能量的供应是通过一或多个激光束以精确加热方式供给，热量/能量在物品即将完成之前被导向先前模制的相互交界表面中的至少一个。
优选地，通过上述作用可以使先前模制的物品在选定区域变形，以便在随后模制时获得与随后材料的改进机械结合度。
优选地，利用激光器在随后的材料通常不会具有足够热量/能量的区域刻出图案或流动通道，随后的模制材料在图案或流动通道中能够流动并获得粘附力，从而与第一模制物品产生足够好的化学/机械连接。
优选地，处理先前模制物品将用于随后模制的交界表面的选定区域，使得在进行模制时在该区域获得与其它材料好的粘附力，同时利用其它区域没有粘附力以形成铰接。
优选地，在塑料物品上设置孔、切口、或去除对应的材料，从而产生更好的机械粘附力或者用作装饰。
优选地，通过分开并引导激光束通过光导纤维在整个焊接区域上施加热量/能量，从而在所有限定的焊接区域受到影响的同时，不需要在处理过程中改变激光器本身的位置。
优选地，在焊接区域上放置或者施加加速剂或催化剂或反射器和/或吸附剂，使得焊接更加有效。
优选地，在焊接处理时，模具的腔用作反射器。
通过以下结合附图的详细描述，本发明的方法和装置所获得的上述优点和其它优点变得更加明显。
附图说明
图1显示了根据本发明的处于闭合状态从上方看具有两个可转动模具部分的装置；
图2显示了图1的装置处于打开状态；
图3显示了根据本发明的处于闭合状态从上方看具有一个可转动模具部分的另一装置；以及
图4显示了图3的装置处于打开状态。
具体实施方式
图1显示了从上方看的两个可转动模具部分1和1’它们可以沿着箭头所示方向相互相对地转动。两个可转动模具部分在静止模具部分2和可动模具部分3之间处于闭合状态。塑性材料的注入分别通过静止模具部分2中的通道4和可动模具部分3中的通道5以及通过芯部6和7进行。在每个可转动模具部分1和1’中被模制的物品在图中显示为半球壳，它们放在一起形成一个完整的中空球。
在冷却、打开模具以及分别沿着箭头方向转动模具四分之一圆周(90°)，再次闭合模具之后，这两个模制的球壳将处于图中最下部位置。这时，它们的外表面8和8’将受到来自激光器10的光束9和9’的作用。在再次打开模具、沿着箭头方向转动模具90°和闭合模具之后，受辐射的表面8和8’将合在一起并粘结成一个完整中空球。在重新打开模具、分别沿着箭头方向使可转动模具部分1和1’转动90°并从模具中推出装配的球之后，模具准备进行如上所述的一个新循环。
图2显示了如图1所示的本发明模具，但它处于打开状态。由于在模具闭合和完全静止时表面8和8’最好被十分精确地辐射，在模具打开和闭合过程中，来自激光器10的光束被中断。
图3显示了仅具有一个在静止模具部分2和可动模具部分3之间处于闭合状态的可转动模具部分1的本发明装置，在静止模具部分2和可动模具部分3中具有通道4和5，塑性材料通过通道4和5在两个相对位置同时注入到模具中。在冷却了材料、打开模具以及沿着箭头方向转动可转动模具90°、并再次闭合模具之后，被模制的(半个)物品将处于图中最下部位置。在此，它在外表面8上受到来自激光器10的光束9的辐射。在重新打开模具、沿着箭头方向转动90°和闭合模具之后，通过通道5向可动模具部分3中的模腔注入新的材料，它粘附在已经模制的(半个)物品的辐射处理表面8上。在冷却、打开模具、再次转动90°之后，组合物品和最终物品处于图中最上部位置准备从模具中推出，并准备开始进行同样的一个新循环。
图4显示了如图3所示的本发明模具，但它处于打开状态。
在图中已经显示了本发明装置的多个实施例，但图中只是显示了本发明的基本原理。如果不是图中难于表示，也可以显示多组分物品的实施例，它们模制在一起常常是有问题的，因为第一模制物品难于可孔的冷却、以及它们的几何形状、材料厚度差别和/或材料组合的相互较差的粘附力。这里，借助于诸如激光或类似能源的精密仪器，对将装配的表面上所选定的精确有限区域进行再次加热将获得迄今为止显著的改进，并且使不容易模制在一起的物品以可接受的质量非常简单地模制在一起。
