Description
技术领域
本发明涉及一种箔包覆模制工艺,特别地涉及一种RFID或光学箔包覆模制工艺,用于具有集成无线标签的诸如线缆保持器的装置。
背景技术
对于尺寸和复杂性增加的产品和过程,对该过程和/或产品中涉及的部分进行标记或标识变得越来越重要。因此,在相应的产品和/或过程中,越来越多的部件,特别是非常小的部分,需要被标记或标识。这可以通过射频识别(RFID)标签来完成,例如集成到相应标签中的RFID芯片。一种替代方案可以是光学标签,例如集成在相应标签中的条形码或公司标志。这种标签应该小,特别是扁平、坚固且易于制造的。解决这个问题的一种可能性是将RFID玻璃转发器模制到标签中,该标签可以具有线缆扎带的形式。
然而,将玻璃转发器模制到诸如线缆扎带的扁平装置中是相对复杂、耗时的过程,该过程包括大量过程步骤。此外,来自其它装置(例如芯片卡片,对比FR2882680 B1或增益令牌,参见DE 69613341 T1)的模制过程使用相对耗时的过程产生。
因此,本发明要解决的目标技术问题是简化和加速具有集成无线标签或标志的装置的制造过程。
发明内容
该问题通过一种用于注射模制具有集成无线标签的装置的方法来解决。
一个方面涉及一种用于注射模制具有集成无线标签的装置的方法。特别地,具有集成无线标签的装置可以是具有集成无线标签的线缆扎带。无线标签可以是电子标签,例如用于无线射频标记的RFID标签,或者是光学标签,例如用于光学标记的条形码等。该方法包括多个方法步骤。
第一方法步骤是将具有由外边缘分开的两个(平行)主表面的标记箔作为无线标签放置到开口模具的模具空腔中,在模具空腔中标记箔由支撑装置保持在适当位置。支撑装置可以至少部分地是模具的一部分。箔的厚度可以小于1mm,优选小于0.4mm,优选小于0.2或小于0.15mm。特别地,箔可以具有夹层结构,该夹层结构具有在两个外层之间的一个标记相关层,例如芯片和天线层。通常,为了保护标记相关层,外层更大并且还可以比标记相关层厚,并且围绕标记相关层(即标记相关区域)形成保护边界区域或框架。在所述边界区域中,两个外层直接附接到彼此,而在由边界区域保护的区域中,标记相关的且因此敏感的层将两个外层分开。
下一步骤是闭合该模具或注射模具。随后将注射材料,优选地热塑性塑料,同时且关于标记箔的主延伸平面对称地注射到邻接标记箔的两个主表面的模具空腔部分中。标记箔的主延伸平面平行于标记箔的两个主表面。模具空腔部分是模具空腔的部分或区段,即该模具是包含不同区段的模具,特别地为整体模具。这些区段中的一些形成所述空腔部分。随后,具有集成无线标签的装置可以从模具中射出。优选地,所述方法步骤以所述顺序执行。特别地,如下面更详细描述的,不执行附加的注射步骤,即,不执行包括将材料注射到模具中的附加步骤。
同时且关于标记箔的主延伸平面对称地将注射材料注射到邻接标记箔的两个表面的模具空腔部分中具有这样的效果,即,在相对表面侧,即例如箔的上侧和下侧,标记箔上的力被平衡。因此,箔在垂直于其主延伸平面的方向上不会显著变形,并且因此在模制过程中不会损坏。此外,具有集成无线标签的装置即承载标记箔的装置可以非常薄,这是因为箔特别是箔的标记相关区域暴露于环境的风险得到了显著的降低。因此,标记箔可以被包覆模制,而无需现有技术中已知的利用逐层模制来使箔稳定的在先步骤。因此,所描述的方法节省了时间和资源。
在有利的实施方式中,上述注射步骤的注射到邻接标记箔的两个主表面的所述空腔部分是使用用于注射材料的入口来完成的,所述入口定位成使得被迫使穿过所述入口的注射材料接触标记箔的作为该标记箔的第一部分的边缘,并且随后同时且关于标记箔的主延伸平面对称地沿着标记箔的两个主表面流动。这例如可以利用入口来实现,该入口形成为平行于边缘延伸的缝。换句话说,材料从标记箔的横向侧注射到邻接标记箔的两个主表面的模具空腔部分中。这里,横向侧是与箔的上侧和下侧不同的一侧,箔的上侧和下侧对应于标记箔的两个主表面。这里,任意地选择术语“上”和“下”以便以直观的方式区分两个不同侧,即独立于标记箔的空间定向。因此,所述空腔部分的入口定向为垂直于标记箔的主平面。这里,入口的定向由在注射材料时材料穿过入口的流动方向和/或入口的横截面的法向矢量限定。
这提供了这样的优点,即,将注射材料同时且对称地注射到邻接两个主表面的模具空腔部分中,并且因此平衡箔的上侧和下侧的力可以非常可靠地实现,特别地例如与在标记箔的相对侧(例如上侧和下侧)处使用两个分开的入口相比更可靠。因此,可以加速该过程。
因此,如果注射材料仅经由所述单个入口被注射到所述空腔部分中或者甚至整个模具空腔中,则是特别有利的。因此,如果入口是单个入口,即,用于注射材料到邻接标记箔的两个主表面的所述空腔部分或者甚至整个模具空腔的唯一入口,则是特别有利的。这导致了该过程更容易控制并且因此可以以增加的速度执行的优点。
在另一有利实施方式中,上述注射步骤包括迫使注射材料的流穿过入口进入所述空腔部分中,在所述空腔部分中所述流被标记箔的边缘分成沿着标记箔的两个主表面流动的两个相等尺寸的子流。因此,考虑到入口的横截面垂直于入口的定向,标记箔的边缘在入口的区域上的正交投影将入口的横截面分成两个相等尺寸的区域。这里,沿着标记箔的边缘流动并且不在箔“上方和下方”流动的流的部分,即,不能通过正交投影投射在箔上并且因此不在垂直于箔的主平面的方向上施加任何力的部分,可以被忽略。优选地,入口的定向垂直于标记箔的主平面的定向,即,入口的定向(该定向可以是其横截面的定向和/或在注射期间注射材料流穿过入口的平均方向)可以平行于标记箔的主平面,因为在本公开的上下文中,平面的定向由其法向矢量限定。
这提供了这样的优点,即,可以以增强的可靠性实现在两个相对侧的力的平衡,即,在对应于标记箔的两个主表面的上侧和下侧的力的平衡,并且特别地,可以避免箔的颤动。因此,可以进一步加速该过程。
在另一个特别有利的实施方式中,具有集成无线标签的装置利用一个单个注射步骤形成,即,通过所谓的“单次注射”形成,其中将注射材料注射到模具中仅在装置的生产过程中执行一次。
这提供了以下优点,即该装置的生产过程更容易控制并且需要更少的时间。
在另一个有利的实施方式中,当由支撑装置保持在适当位置时,支撑装置仅在标记箔的一个或多个区域中与标记箔机械接触,所述一个或多个区域距标记箔的标记相关区域的最小距离>0mm、特别地>0.3mm、优选地>0.6mm。在标记箔的主平面中测量该距离。标记箔的标记相关区域可以是RFID箔的区域,例如芯片和天线所处的区域。因此,标记相关区域可以是标记箔的芯片天线区域,只要标记箔包括或者是用于诸如RFID标记的无线射频标记的芯片天线箔。因此,标记相关区域不与支撑装置和/或模具机械接触。换句话说,标记相关区域在空腔中自由浮动,仅由箔的框架保持在适当位置。作为标记相关区域的替代或补充,标记相关区域例如是芯片天线箔、特别是RFID标记箔的芯片天线区域,标记相关区域可以是光学代码区域,例如布置有光学标记箔的条形码、矩阵码等的区域。
这提供了这样的优点,即,标记箔的标记相关区域由注射材料保护以免受环境的影响,从而增强了无线标签的可靠功能。此外,在生产过程中,支撑装置不太可能损坏标记箔的标记相关区域。此外,施加在箔上的力可以增加,从而在注射材料的注射期间导致箔的稳定和精确的固定,再次使得能够增加过程速度。
在另一有利的实施方式中,上述放置步骤包括通过真空和/或通过定位销将标记箔保持在适当位置。相应地,支撑装置包括用于将标记箔保持在限定位置的真空和/或销装置。
这提供了这样的优点,即能够实现标记箔的特别精确的定位,这进一步增加了在标记箔的不同侧的力的平衡的精度,增加到上述优点。
在另一有利实施方式中,上述闭合步骤包括将标记箔夹在或捕获在支撑装置的一组至少一对相对表面之间,相对表面优选地为偶数对,例如至少六对、至少八对、至少十对或至少十二对匹配表面。相应的相对表面可以由模具的独立可移动部分形成,例如,在注射模具中,即在A板中的相应的一对相对表面中的一个表面,以及在注射模具中,即在B板中的相应的一对相对表面中的另一个表面。然后,在闭合该模具时,这些相对表面被朝向彼此按压,因此将标记箔固定在给定位置,即,其初始位置。替代地或另外地,支撑装置可以包括附加元件,例如弹簧元件和/或液压元件,其中每对表面中的至少一个表面被所述弹簧元件和/或液压元件压向另一表面。因此,支撑装置(也)可以用作夹持或夹紧装置。优选地,标记箔在其边缘处被夹持,这意味着当模具闭合时,相应的一对相对表面中的相对表面部分地彼此接触。相对表面优选地仅在上述标记相关区域之外,即仅在框架处接触标记。
这提供了标记箔特别可靠地保持在其位置的优点。这确保了箔的相对侧的力的特别良好的平衡,并且允许以增加的速度进行注射模制,同时维持标记箔的以及因此无线标记的可靠功能。
在另一有利实施方式中,标记箔是或者包括用于无线射频标记的芯片天线箔,特别是用于射频识别的射频识别(RFID)箔,优选地用于无源标签射频识别。附加地或替代地,标记箔是或包括用于光学标记的光学箔,特别是用于光学条形码识别的光学条形码箔和/或用于光学矩阵代码识别的光学矩阵箔和/或用于光学标识或图片识别的光学标识或光学图片箔。在无线射频标记的情况下,注射材料优选地对于在识别标签或标志期间使用的射频信号是透明的。对于热塑性塑料通常是这种情况。在无线光学标记的情况下,注射材料优选地对于光学信号,即对于可见光谱的光或对于可见光谱的给定子光谱是透明的。
所提出的方法对于芯片天线箔,特别是RFID箔特别有利,因为这些箔非常敏感,因此通常在注射模制中使用几个注射步骤来处理。因此,利用所提出的方法,可以可靠且快速地生产具有集成无线射频标签特别是RFID标签的装置。至于光学标记或标志,利用所提出的方法避免了在模制过程期间箔的变形,从而导致改善的易读性,并且特别是在公司标志或图片的情况下,导致标志或图片的清楚且明确的呈现。
在又一有利实施方式中,具有集成无线标签的装置可以是线缆保持器或令牌,特别地为游戏硬币或智能/芯片卡片或用于另一装置的中间产品。特别地,具有集成无线标签的装置可以是扁平装置,即,在主延伸方向上的主延伸远大于其在最小延伸方向上的延伸的装置。例如,长度可以是其厚度的至少四倍,优选地至少十倍或甚至至少15倍大。
这提供了这样的优点,即箔特别适于包括在装置中,并且由于所述装置通常以大量生产,因此加速生产过程的效果特别高。
另一方面涉及一种用于根据上述方法注射模制具有集成无线标签的装置特别地为线缆扎带的模制装置。
另一方面涉及一种具有通过根据任何所述方法进行的注射模制而形成的集成无线标签的装置特别地为线缆扎带。
模制装置和具有集成无线标签的装置的优点和有利实施方式对应于所述方法的优点和有利实施方式。

通过以下示意图进一步描述示例性实施方式。在其中,
图1示出了具有集成无线标签的装置、这里是线缆扎带的示例性实施方式的立体图;
图2示出了标记箔的示例性实施方式的立体图;
图3示出了具有图2的标记箔的开口模具的示例性实施方式的立体图;
图4示出了图3的开口模具的俯视图;以及
图5示出了将材料示例性地注射到闭合的模具的示例性实施方式中的3D图示的立体图。
在附图中,相同或功能相同的元件具有相同的附图标记。
具体实施方式
图1示出了具有集成无线标签2的装置1的示例性实施方式的立体图。在本实施例中,装置1是线缆扎带,其中无线标签2布置在线缆扎带1的头部3和尾部4之间。无线标签2是或包括标记箔5,在本实施例中,标记箔是用于RFID的芯片天线箔,简称RFID箔。
标记箔5在图2中更详细地示出。标记箔5在标记箔5的中心具有标记相关区域6,该标记相关区域6在这里由保护边缘或框架7围绕。在本实施例中,标记箔5还具有在Z方向上在相对端处的两个孔8a、8b,用于将标记箔5精确地调整到其适当位置。在作为RFID箔的标记箔的本实施例中,标记相关区域是天线芯片区域,标记箔5的RFID功能所需的天线和芯片位于该天线芯片区域。因此,标记相关区域6比框架7更容易受到损坏。
在图2中,提供了标记箔5的两个主表面9a、9b中的一个的视图。这里,为了说明的目的,所示主表面可以称为上主表面9a而没有定界字符,因为其在空间中的定向是任意的。上主表面9a和下主表面9b(现在不可见)通过外边缘10彼此分开。
图3示出了用于注射模制装置1的模具11的示例性实施方式的立体图,在本实施例中,该装置是具有集成无线标签2的线缆扎带。这里,为了示例性说明的目的,图2的标记箔5被放置到模具空腔中,在该模具空腔中,标记箔由支撑装置13保持在适当位置,该支撑装置将在后面参照图4更详细地描述。
标记箔5由支撑装置13保持在适当位置,使得包括标记箔5的模具空腔部分14被分成邻接两个主表面9a、9b的两个模具空腔部分14a、14b。有利地,两个模具型空腔部分14a、14b具有相等的容积。注意,为了说明的目的,仅示出了模具11的一半,其可以被称为模具11的下半部。
因此,标记箔5的边缘10被固定在适当位置,使得在图的左上方处注射到模具空腔12中的注射材料流(即,从注射部位15(这里,对应于线缆扎带的头部3)在X方向上经由入口16流动穿过模具空腔12流入模空腔部分14中的注射材料流)被边缘10分成沿标记箔5的两个主表面9a、9b流动的两个子流,这两个子流具有相等的尺寸(见图5)。因此,在本实施例中,入口16定位成使得当注射材料被注射到闭合的模具11中时,注射材料在随后沿着标记箔5的两个主表面9a、9b流动之前接触标记箔5的边缘10(见图5)。边缘10可被认为位于入口16的竖直中心,导致注射材料21流的水平分割(图5),因为与两个相等尺寸的子流相对应,到入口16的直径区域上的正交投影将直径区域分成两个相等尺寸的区域。这里,从图4中还可以清楚地看出,入口16的定向以及因此注射步骤中的注射材料的流动方向平行于主表面9a、9b延伸,即平行于标记箔5的主延伸平面,即x-z平面。
图4示出了图3的模具11的俯视图。支撑装置13包括多对相对表面17a、17b、18a、18b、19a、19b,其中仅示出了相应对的相对表面中的一对,作为模具11的第二半部包括(优选对称的)模具空腔部分14的第二半部,即模具空腔部分14a(图3),在此未示出。
当标记箔5被放入模具11中时,它与框架7一起被置于所述表面17a至19b上,以避免支撑装置13与标记相关区域6,特别是RFID箔的芯片和天线的机械干扰。因此,标记箔5的标记相关区域在模具空腔12中自由地浮动。如图4所示,表面17a、17b、18a、18b、19a、19b优选地在其边缘10处接触标记箔5,使得当模具11闭合时,标记箔5被夹在一些相对表面17a、17b、18a、18b之间,优选地但不是必须地夹在所有相对表面17a至19b之间。如果在边缘处被夹持,这导致边缘10的硬化,这促进注射材料21(图5)同时且对称地流入邻接标记箔5的两个主表面9a、9b的模具空腔部分14a、14b中,并且平衡标记箔5在其上侧和下侧的力。
在本实施例中,成对的相对表面17a至19b被布置成关于注射材料21的主流动方向(这里为X方向)以及在垂直于流动方向的线(即,Z方向上的线)上关于标记箔5的主要延伸对称。即,在当前的实施例中,对于位于流动方向上游(图的左侧)的每对相对表面17a、18a,存在位于流动方向下游(图的右侧)的对应的对称配对物17b、18b。在本实施例中,最靠近入口16的两对中心的相对表面17a、17b具有比更远离入口16的外部成对的相对表面18a、18b、19a、19b更小的面积。这结合了保持标记箔5的增强的可靠性与通过支撑装置13注射材料流动穿过模具空腔12的最小侵入。这结合了保持标签箔片5的增强的可靠性和通过支撑装置13使注射材料流通过模具腔12的最小的突出。在本实施例中,上游的一对中心相对表面17a将流动穿过入口16的注射材料流竖直地分成两个相等尺寸的子流。这对应于上面解释的由边缘10进行的水平分割。
在本实施例中,位于具有最大距离的标记箔5的相对端处的最外面成对的相对表面19a、19b具有真空装置的特征。因此,在本实施例中,相应表面中的至少一个具有孔20,当连接到真空时,所述孔允许通过真空将标记箔5保持在适当位置。相应地,所述最外面的相对表面19a、19b在这里不与边缘10接触。所述最外面成对的相对表面19a、19b在本实施例中也具有最大的面积,因为它们彼此相距最远,并且因此在成对的相对表面19a、19b之间出现的张力大于因此在彼此更靠近的成对的相对表面(例如成对的相对表面17a、17b)之间出现的张力。
图5示出了对于图3和图4所示的示例性模具11,注射材料21在不同时间t1、t2、t3的流动。沿着这里平行于x方向延伸的注射方向D,注射材料21在时间t1在注射部位15(图3、图4)进入模具空腔12。当其在时间t2填充模具空腔12时,其开始通过入口16进入具有标记箔5的模具空腔区域14。在第三随后的时间t3,如通过注射材料21的边缘21a和21b显而易见的,其同时且关于标记箔5的主延伸平面对称地移动到邻接标记箔5的两个主表面9a、9b的模具空腔部分14a、14b中。因此,注射材料21的横向注射有利地导致标记箔5上的平衡的竖直力(竖直涉及图5中的y方向)。
这具有的效果是,标记箔5保持完整并且由注射材料21良好地保护,允许利用单个注射步骤生产具有集成无线标签的注射模制装置。
