Description

用于测定粘结剂接条或密封剂接条的固化特性的方法和装置
技术领域
本发明涉及一种用于测定粘结剂接条或密封剂接条的固化特性的方法和装置。
背景技术
粘结剂和密封剂主要借助涂覆喷嘴以称作接条(Raupe)的带的形式涂覆到涉及的工件上，其中，接条可构造成连续无间隙的接条或者构造成多个彼此间隔布置的接条区段的依次序列。必须及时在粘结剂或密封剂固化之前进行设有接条的工件的再加工。因此，在许多应用中有重要意义的是，在固化过程开始前，使用者知道粘结剂和密封剂的固化特性。通常，涂覆测试接条到工件上并且进行实施刮铲测试，在该刮铲测试中在预先确定的时间点以薄的刮铲压到接条上。在此，由于刮铲压力而发生的接条变形表示在粘结剂和密封剂涂覆到工件上之后在预先确定的时间点该粘结剂和密封剂的固化程度。但是，该方法受到批评，该方法相当强地依赖于实施人员，因为不同的人员会不同强度地用刮铲压到接条上并且即使在由单个测试人员实施刮铲测试时也不保证其在不同的预先确定的时间点始终以相同的力压到接条上。
发明内容
本发明的目的在于，提供一种用于测定粘结剂接条或密封剂接条的固化特性的方法和装置，该方法和该装置提供更合理或更客观的结果。
根据本发明，该目的通过带有权利要求1的特征的方法和带有权利要求8的特征的装置来实现。本发明有利的设计方案是从属权利要求的内容。
本发明的思想在于，当将测试体放置到接条上并且测试体以其重力作用到接条上时，测试体始终以至少近似相同的力加载接条，并且因此可以提供可理解的和客观的结果。在此优选，多个和优选全部的测试体构造相同，使得测试体至少近似以相同的重力作用到接条上。有利的是，测试体不仅在重量方面构造成相同，而且必要时也在它们的形状和/或所使用的材料方面构造成相同，使得靠在接条上的放置面也始终相同。在不同的、预先确定的放置时间点将测试体放置到接条上，并且在预先确定的最终时间点测量由测试体引起的接条的变形。该变形用作固化时间的尺度，使得尤其在使用双组份或者三组份粘结剂或密封剂的情况下，在投入制造之前可再次改变粘结剂或密封剂的成分。
作为粘结剂或密封剂在放置时间点的固化的尺度，尤其可考虑相应的测试体下沉到接条中的下沉深度。此外，这可通过简单的方式来测量。大的下沉深度意味着，粘结剂或密封剂在所涉及的放置时间点仅少量固化，小的下沉深度或零下沉深度意味着，粘结剂或密封剂在所涉及的放置时间点已大部分固化或完全固化。
优选以恒定的时间间隔将测试体放置到粘结剂接条或密封剂接条上，使得在彼此间隔恒定的放置时间点获得测量值，从而例如简化插值。
根据本发明的一种有利的设计方案，将保持装置放置到工件上，保持装置具有用于测试体的直线引导部，测试体能朝工件的方向在直线引导部中直线引导。然后将测试体在放置时间点引入到直线引导部中并且放置到粘结剂接条或密封剂接条上，使得测试体以它们的重量加载粘结剂接条或密封剂接条。保持装置的使用简化了结果的可溯源性，为此测试体的方置与操作人员的灵巧程度基本上不相关并且简化了测试体在接条上的定位。作为测试体，适宜地使用金属销，其优选地具有朝向下侧的放置面减小的厚度。金属销具有大的单位重量，使得即使在使用相对小的测试体时也可实现：接条产生足够的变形。当销具有小的放置面时，这导致产生增大接条变形的更高的压力。
保持装置有利的是穿孔的板，并且测试体在板的形成直线引导部的孔中有间隙地引导。由此实现了根据本发明的装置的简单的构造。
附图说明
接下来根据在附图中示意性示出的实施例详细产生本发明。附图如下：
图1以侧视图示出了涂覆在工件上的粘结剂接条，包括用于测定其固化特性的装置，以及
图2以透视图示出了图1中的细节。
具体实施方式
在图中示出了粘结剂接条10，其涂覆在工件12上。此外在图1中示出了装置20，该装置用于测定粘结剂的固化特性。装置20具有呈纵向延伸的板的形式的保持装置22，保持装置具有在一行中彼此相距相同间隔布置的孔24。孔24形成了直线引导部，用于多个在形状、材料和重量上至少相似并且在示出的实施例中构造相同的金属销26，金属销具有圆柱形的外轮廓，其以略微的间隙装入孔24中并且在那里沿垂直于工件12的表面的方向延伸地被引导。每个金属销26的横截面朝下侧的放置面28逐渐变小，使得其重量施加在相对小的面积上。
为了测定形成接条10的粘结剂的固化特性，首先将接条10涂覆在工件12上。在此之后，将板22借助于未详细示出的支撑腿放置在工件22的表面上，并且以到预定的放置时间点恒定的时间间隔将金属销26引入到孔24中并且以它们的放置面28放置到粘结剂接条10上。在此示出的实施例中，在粘结剂接条10涂覆到工件12上的一分半钟之后，将第一金属条26放置到接条10上，在粘结剂接条涂覆到工件上的三分钟后放置第二金属条26，在粘结剂接条涂覆到工件上的四分半钟之后放置第三金属条26，依次类推。因为粘结剂随时间推移而固化，所以最先放置到接条10上的金属销26下沉得比最后放置到接条10上的金属销26更深。这在图1中示出，其中，在最后放置并且几乎未下沉到接条10中的金属销26上铺有水平延伸的板条32。在预定的放置时间点放置的金属条26的下沉深度(在图1中通过到板条32的间距来表示)，则表示了粘结剂的固化特性的特征尺度。在此，在预定的最终时间点测量下沉深度，该预定的最终时间点优选是粘结剂开始完全固化的时间点。
概括来说是如下内容：本发明涉及一种用于测定粘结剂接条或密封剂接条10的固化特性的方法，其中，将粘结剂接条或密封剂接条10涂覆在工件12上，其中，在不同的预定的放置时间点将多个测试体26放置到粘结剂接条或密封剂接条10上，并且其中，在预定的最终时间点测量由于测试体26引起的粘结剂接条或密封剂接条10的变形。
