Description

RFID标签
技术领域
本发明涉及包括RFID标牌(RFID tag)的RFID标签(RFID label)，该标牌包括RFID天线和IC，该IC附接至天线上，使得天线和IC形成RFID标牌。
在下文中，将频繁使用RFID(射频识别)标牌的表述。RFID标牌是旨在附接至射频识别系统中待识别的对象上的标牌。
RFID标牌包括RFID天线和RFID IC(集成电路或微芯片)，该IC电连接至天线上。
RFID标签在本上下文中是携载RFID标牌的标签。标签旨在通过标签的粘合层附接至不同种类的物体上。
现有技术-问题
图A公开了RFID标签的常规三层结构。RFID标签结构包括具有天线(A2)和IC(A3)的基底(A1)。结构还包括具有覆盖天线和IC的粘合剂的面纸层(A4)、粘合剂(A5)和硅化剥离层(A6)，当将RFID标签附接至物体上时，该硅化剥离层被去除。
图B公开了RFID标签的常规双层结构。结构包括具有天线(A2)和IC(A3)的基底(A1)。结构还包括粘合剂(A5)、硅化剥离层(A6)，当将RFID标签附接至物体上时，该硅化剥离层被去除。
上述现有技术的缺点在于，它们都需要若干层和/或剥离层以附接标签，这进而是昂贵的而且不是环境友好的。
发明目的
本发明的目的是提供更环境友好的RFID标签，其与现有技术相比，更成本有效，并且进而解决了上述问题。
发明内容
根据本发明，RFID标签的特征在于，RFID标签还包括：
-具有第一表面和第二表面的长形基底，其中，第一表面被硅化，并且第二表面承载RFID标牌，以及
-被布置在基底的第二表面上和RFID标牌上方的粘性粘合层。
本发明的附图和具体实施方式
图A和图B公开了具有两个和三个标签结构的传统RFID标签的现有技术，参见上文“现有技术-问题”。
图1公开了根据本发明的RFID标签的示意图。
在下文中，将参照图1更详细地描述本发明。本发明公开了RFID标签1，RFID标签1包括基底2，基底2具有第一表面3和背离第一表面3的相反的第二表面4。基底优选地由纸或纸板材料制成。然而，技术人员认识到其他非导电基底材料也是可以的。
第一表面3被硅化，即表面已经用硅涂覆或处理，使得表面具有不粘特性。第二表面4是未处理的，即它没有被硅化。
RFID标签还包括RFID标牌7，该标牌包括RFID天线5和集成芯片(IC)6。IC电连接至天线，使得天线和IC形成RFID标牌。RFID标牌在未处理的第二表面4上附接至基底。
技术人员认识到，可以有许多方式在第二表面上形成RFID标牌。在形成天线的第一实施方式中，导电固体颗粒以预定义图案形成在腹板(web)的第二表面上。
然后固化导电材料以形成凝固的、更紧凑的天线图案。这可以例如通过应用合适的加热器加热来实现。因此，优选地将导电材料加热至超过导电材料的特征熔化温度的温度。
可以按照WO2013/113995、WO2009/135985、WO2008/006941和WO2016/189446中的一个或多个中公开的方式进行导电颗粒的转印和固化以及凝固。所有所述文献在此通过引用，全文并入本文。
此外，也可以使用形成图案化的导电材料的其他方式。在第二实施方式中，RFID天线的形成可以通过使用导电墨的增材印刷(additive printing)来进行。导电墨是包含导电颗粒的墨。导电墨例如可以是银墨、铜墨或石墨烯墨。然后通过将导电墨干燥或用热空气、辐射(UV、EB)、光子固化、激光或一些其他处理方法处理导电墨，使其导电。
在第三实施方式中，通过首先为第二表面提供优选为铝箔的导电层来形成RFID天线。然后减去部分导电层，使得套筒材料腹板(collar material web)上的剩余导电层形成RFID天线。将导电层减去成期望的导电图案可以例如通过切割、研磨、刷涂等来进行。
此后，方法包括将RFID IC附接至天线上的步骤，使得在IC和天线之间建立电连接，其中，形成RFID标牌3。
RFID标签还包括应用至基底的第二表面4上和RFID标牌7上方的粘性粘合层8。因此，粘合层覆盖天线5、IC 6和第二表面4。
长形基底2承载若干RFID标牌7，这些标牌被布置在基底的第二表面上。RFID标牌以两个相邻RFID标牌之间具有预定距离的方式进行布置。
在优选实施方式中，基底在两个相邻标牌之间穿孔，使得标牌可以在RFID标牌应用过程中手动或自动分离。然而，技术人员认识到其他分离方法也是可以的，例如经由剪刀或刀或类似设备切割，其中穿孔不是必需的。
RFID标签被卷起以形成卷，其中，硅化的第一表面3面对并覆盖粘性粘合层8。由于硅化表面4覆盖了粘合层8，在卷中，不需要额外的硅化衬垫或类似物来保护粘合层8。
完成的粘性RFID标签可以通过在应用期间切割标签并然后将RFID标签直接固定至期望的物体上来实现。
与传统的RFID标签相比，本发明具有几个优点。本发明的标签仅由一个单基底层组成，即不需要剥离层或附加层。本发明的主要优点是使原材料的量最小化，这使得成本最优化和环境友好的非常薄的产品结构成为可能。这意味着每个卷将具有大约两倍以上的标签，这进而意味着运输成本和相关的污染将大大降低。因为卷较少地需要调换，生产过程变得更高效。与常规RFID标签相比，产品的碳足迹明显减少。
在上文中，已经基于一些具体实施方式描述了本发明。然而，本领域技术人员认识到，在所附权利要求书的范围内，其他实施方式和变型也是可以的。
