Description

贴膜设备及贴膜方法 技术领域
本发明涉及贴膜应用领域，尤其涉及导电薄膜材料生产领域的生产装置。
背景技术
胶带在工业生产以及日程生活中的应用极其广泛，然而在很多场合的使用中均需要手工进行贴胶带，手工操作虽然能保证其粘贴的灵活性，然而在大型生产现场，这一手工环节往往限制了整个工艺流程的速度；并且手工粘贴的过程中会因为操作者的熟练程度以及粘贴速度等等因素出现不同程度的粘贴不规整或者粘贴部分出现气泡等问题，这些因为人为操作而产生的缺陷往往会影响整个产品或者包装的性能。同样的，在其他需要将一个薄膜贴附于一个目标物上的应用中，也存在类似的问题。更为重要的是，在导电薄膜行业往往没有应用胶带的行业场景，如果将胶带跨行业应用到导电膜生产行业中，则本身就是一种创新应用，进一步的如何实现自动化处理胶带贴膜(自动化贴覆或去除胶带)将更会是一个值得解决的技术问题，因为导电薄膜生产领域具有独特的行业特性，这些与导电薄膜材料本身的特性密切相关，而如果完全采用人工处理胶带的贴覆或去除，则成本高、效率低、容易出错等。
因此，有必要提出一种改进的方案来克服上述问题。

具体实施方式
为更进一步阐述本发明为达成预定发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明的具体实施方式、结构、特征及其功效，详细说明如下。
图1为本发明的贴膜设备在一个实施例中的一个视角的立体结构示意图，图2为图1中的贴膜设备的另一个视角的立体结构示意图。如图1和图2所示的，其显示了两台依次前后设置的贴膜设备1a和1b，在其他的实施例中，可以根据需要设置所述贴膜设备的个数，比如可以为1台，也可以为3、4或更多台。所述贴膜设备1a和1b可以用于将贴膜通过粘贴或其他方式贴附于导电薄膜5等目标物上，该过程全程无需人工参与，提高了生产效率，产品一致性高。
如图1和图2所示的，所述贴膜设备1a或1b包括机架50、形成于机架50上的工作平台40、贴膜组件10、贴膜位置调整装置20、贴膜位置定位装置30。
所述工作平台40可以承载导电薄膜5并带动所述导电薄膜5向前运动，所述工作平台40由平台动力设备驱动，在所述工作平台40上设置有码盘41。所述码盘41用于测量所述导电薄膜5的运动速度，并将该速度反馈给所述平台动力设备，所述平台动力设备基于所述码盘41反馈的运动速度来调控所述导电薄膜5的运动速度。
如图12所示的，所述导电薄膜5包括位于指定位置的引线区51，本发明中的所述贴膜组件10可以在所述导电薄膜5的引线区51上贴上贴膜82，以实现对所述引线区51的遮盖。在其他实施例中，很显然，所述工作平台40也可以运输其他需要贴附贴膜的薄膜或其他物品，本发明中可以将它们统称为待贴 膜的目标物，本文中主要以导电薄膜5为例进行介绍。所述贴膜82也可以是具有粘性的贴膜，也可以是不具有粘性的贴膜。
图3为图1中的一个贴膜设备的正面立体结构示意图。结合图3所示的，所述贴膜位置定位装置30可以用于定位所述导电薄膜5上的引线区的横向位置和纵向位置，其中所述纵向为所述导电薄膜的传送方向X，简称X方向，所述横向为所述导电薄膜的传送方向的垂直方向Y，简称Y方向。所述贴膜位置定位装置30包括相机31、光源32和图像识别单元(未图示)。所述相机31用于拍摄所述导电薄膜5，所述光源32用于在所述相机31拍摄时进行补光。所述图像识别单元用于基于所述相机31拍摄的图像识别出所述导电薄膜5的引线区的横向位置和纵向位置。
结合图3所示的，所述贴膜位置调整装置20包括固定于机架50上的横向延伸的横向导轨21、能够在所述横向导轨21上滑动的横向滑块22和滑块驱动装置23。所述贴膜组件10与所述横向滑块22相连，所述滑块驱动装置23可以驱动所述横向滑块22沿着所述横向导轨21横向移动，通过所述横向滑块22的横向移动能够带动所述贴膜组件10的横向移动。这样，即便所述导电薄膜5在传送时发生了横向位置偏移，所述贴膜位置调整装置20也可以基于定位得到的引线区的横向位置调整所述贴膜组件10的横向位置，从而可以更为精确的将贴膜贴附于所述导电薄膜的引线区上。所述滑块驱动装置23可以为电机。
在一些实施例中，也可以不设置所述贴膜位置调整装置20，此时所述贴膜组件10可以直接固定在机架50上，这样所述贴膜组件10的横向位置就是不可调整的了，为了保证贴膜设备的正常运行，需要尽量确保所述工作平台40传输的导电薄膜5发生的位置偏移是能够被接受的。
在一些实施例中，也可以不设置所述贴膜位置定位装置30，此时所述贴膜设备需要事先知晓所述导电薄膜5的引线区的位置，只要所述导电薄膜5的引线区的位置不发生偏移，那么所述贴膜组件10就可以将贴膜82自动贴附在所述导电薄膜5的引线区51上。
图4为图3中的贴膜设备的侧视结构示意图；图5为图3中的贴膜设备的反面立体结构示意图。所述贴膜组件10包括剥离机构100、辊压组件200、上料机构300、回料机构400、半切装置500、长度调节装置600、贴膜组件基体700以及贴膜组件基体驱动装置800。
所述剥离机构100、辊压组件200、上料机构300、回料机构400、半切装置500、长度调节装置600均设置于所述贴膜组件基体700上，所述贴膜组件基体700的运动能够带动所述剥离机构100、辊压组件200、上料机构300、回料机构400、半切装置500、长度调节装置600同步运动。所述贴膜组件基体驱动装置800的一端固定于所述横向滑块21上的，另一端固定于所述贴膜组件基体700上，所述贴膜组件基体驱动装置800能够驱动所述贴膜组件基体700在初始位置和下压位置之间移动。优选的，所述贴膜组件基体驱动装置800可以为气缸。
图6为图3中的剥离机构100的立体结构示意图。如图6所示的，所述剥离机构100包括剥离机构本体110和位于所述剥离机构本体110末端的剥离边缘120，所述剥离机构本体110包括第一导引面111和第二导引面112，第一导引面111和第二导引面112交汇于所述剥离边缘120。所述辊压组件200包括间隔设置的第一压辊210和第二压辊220，第一压辊210较第二压辊220更靠近所述剥离机构100的剥离边缘120。第一压辊210和第二压辊220均具有初始状态和压紧状态。图10为本发明中的复合料带80的结构示意图。如图10所示的，所述复合料带80包括基膜81和贴附于所述基膜81一侧的贴膜82，所述贴膜82的与所述基膜81贴合的第一表面具有粘性，所述贴膜82的与第一表面相对的第二表面无粘性。
如图8所示的，复合料带80被驱动的沿所述剥离机构本体110的第一导引面111朝向所述剥离边缘120运动，并在所述剥离边缘120被分离成位于靠近剥离机构本体110一侧的基膜81和位于远离所述剥离机构本体110一侧的贴膜82，其中所述基膜81翻过所述剥离边缘120被驱动的沿第二导引面112远离所述剥离边缘120运动。优选的，如图6所示的，所述薄膜边缘120可以是一个弧面边缘，而不是一个尖锐的边缘，这样可以更有利于所述基膜81顺利通过所述剥离边缘120。
为了便于剥离所述复合料带80，如图6和7所示的，第一导引面111和第二导引面112之间的夹角可以小于15度，比如10度，12度等。所述剥离机构本体110的形成第一导引面111的第一侧设置有导引槽130，所述导引槽130的底面就是所述第一导引面111。所述导引槽130用于导引所述复合料带80。所述导引槽130的宽度可以与所述料带的宽度相匹配。
所述剥离机构本体110的第一侧的靠近所述剥离边缘的部分设置有弧形凹坑140，所述弧形凹坑140与第一压辊210的外缘匹配且紧邻设置，但与所述剥离机构的弧形凹坑不接触。这样，可以使得第一压辊210的辊压处211可以与所述剥离机构100的剥离边缘120尽可能的靠近，以便第一压辊210能够更容易压到分离的贴膜82。
如图8所述的，在处于压紧状态时，第一压辊210和第二压辊220依次辊压于分离的贴膜82的无粘性的第二表面，使得所述贴膜82的第一表面粘贴于承载于所述工作平台40上的所述导电薄膜5的引线区上。
如图7所示的，第一压辊210和所述贴膜组件基体700是同步运动的，在所述贴膜组件基体700位于初始位置时，第一压辊210位于初始状态，此时第一压辊210与所述工作平台40上的导电薄膜5间隔一段距离。如图8所示的，在所述贴膜组件基体700被所述贴膜组件基体驱动装置800驱动至下压位置时，第一压辊210随着所述贴膜组件基体700一同下压进入压紧状态，此时第一压辊210压于所述工作平台40上的导电薄膜5上。具体的，可以基于所述贴膜位置定位装置20定位得到的所述引线区的纵向位置确定将所述剥离机构100从所述初始状态切换至所述压紧状态的时机，以使得所述剥离机构100在所述压紧状态时正好可以对准所述引线区。
如图5所示的，所述贴膜组件10还包括设置于所述贴膜组件基体700上的压辊驱动装置221。所述压辊驱动装置221的一端与所述贴膜组件基体700固定连接，另一端与第二压辊220固定连接。该压辊驱动装置221驱动第二压辊220在初始状态和压紧状态之间切换。第二压辊220独立于第一压辊210运动，第二压辊220可以晚于、早于或同时与第一压辊210从初始状态进入压紧状态，只要第二压辊220能够及时的压到分离的贴膜82即可，不过第二压辊220通常要较第一压辊210迟预定时间从压紧状态到回归所述初始状态，如图8和图9，以便第二压辊220能够将分离出的贴膜82从头压到尾。所述压辊驱动装置221可以是气缸。
所述上料机构300用于向所述剥离机构100输送复合料带80，其运动方向如图8中的D1，所述回料机构400用于将从所述复合料带80上的基膜81从所述剥离机构100带走，其运动方向如图8中的D2。在所述辊压组件200处在所述压紧状态时，所述复合料带80被所述上料机构300和/或所述回料机构400 驱动，且与所述工作平台40上的导电薄膜5同步运动，所述工作平台40上的导电薄膜5的运动方向如图8中的方向X，从所述复合料带80上逐渐分离出的贴膜82经过所述辊压组件200的辊压与所述导电薄膜5的引线区粘贴在一起。所述第一压辊210的转动方向可参见图8中的r2，所述第一压辊210的转动方向可参见图8中的r3，而导向辊320的转动方向参见图8中的r1。
如图4所示的，所述上料机构300包括放料盘310和一个或多个导向辊320，所述回料机构400包括一个或多个导向辊410、一个主动辊421、一个从动辊422、回料盘430和回料驱动装置440，所述回料驱动装置440驱动所述主动辊421、从动辊422、回料盘430转动，进而带动所述复合料带80和所述基膜81运动。所述放料盘310上设置有制动器，为所述放料盘310提供一定的阻力。所述制动器可以是磁粉制动器。所述回料驱动装置440可以是同步电机。所述从动辊422能够在辊驱动装置4221的驱动下在夹紧位置和远离位置之间移动，在所述从动辊422位于所述夹紧位置时，所述基膜81被夹持于主动辊421和第二主动422辊之间。所述辊驱动装置4221可以为气缸。当需要更换复合料带80时，所述辊驱动装置4221带动从动辊抬起，更换复合料带。
如图11所示的，所述半切装置500可以用于在所述复合料带80被送入所述剥离机100构前，将所述复合料带80上的贴膜82切断成预定长度L的贴膜段82n。所述半切装置80包括有半切刀510和半切驱动装置520。所述半切驱动装置520驱动所述半切刀510进行切割动作，所述半切刀510将所述复合料带80上的贴膜82切割成预定长度的贴膜段82n。
所述长度调节装置600能够调节所述贴膜段的预定长度L。所述长度调节装置600包括切缝传感器610和刻度板620，所述切缝传感器610到所述剥离机构100的剥离边缘120之间胶带的长度等于所述预定长度L的正整数倍，比如1、2倍等。所述切缝传感器610感应到切缝后，暂停将所述复合料带80送入所述剥离机构100，同时所述贴膜组件基体700从下压位置回复至所述初始位置，第一压辊210和所述剥离机构100由压紧状态恢复至所述初始状态。
为了便于理解，下面结合图7-图9对所述贴膜设备的贴膜原理进行详细介绍。
如图7所示的，剥离机构100、第一压辊210和第二压辊220均处于初始状态，此时所述工作平台40驱动位于其上的导电薄膜5向前延伸X方向运动。 为了凸显所述导电薄膜5，在图7-9中故意省略了所述工作平台40，实际上所述工作平台40就位于所述导电薄膜5的下方。此时，所述上料机构300和所述收料机构400可以不动。
在所述导电薄膜5运动至指定位置时，所述贴膜组件基体驱动装置800带动贴膜组件10下压，如图8所示的，此时剥离机构100、第一压辊210已从初始状态进入到了压紧状态，第二压辊220在压辊驱动装置221带动下也已从初始状态进入到了压紧状态。此时，所述复合料带80被所述上料机构300和/或所述回料机构400驱动且与所述工作平台40上的导电薄膜5同步运动，即导电薄膜5的运动速度与所述复合料带80的运动速度基本一致。从所述复合料带80上逐渐分离出的预定长度的贴膜段82n依次经过第一压辊210和第二压辊220的辊压与所述导电薄膜5的引线区粘贴在一起。具体的，可以基于所述贴膜位置定位装置20定位得到的所述引线区的纵向位置、所述导电薄膜的运动速度确定所述导电薄膜5是否运动至指定位置。
一段时间之后，在所述切缝传感器610感应到所述导电薄膜5的切缝时，所述贴膜组件基体700被驱动的从下压位置回复至所述初始位置，而第一压辊210由压紧状态恢复至所述初始状态，同时暂停将所述复合料带80送入所述剥离机构100。如图9所示的，此时剥离机构100、第一压辊210已由压紧状态恢复到了初始状态，第二压辊220依然处于压紧状态，使得第二压辊220能够将分离出的贴膜段82n从头压到尾。
在延迟预定时间后，第二压辊220被驱动的从压紧状态恢复至初始状态，这样所述撕膜设备又回到了图7所示的状态。至此一次贴膜过程结束，重复上述过程，就可以完成多次贴膜。
在一个优选的实施例中，在所述第一压辊210进入压紧状态前，所述复合料带80被送入所述剥离机构100预剥离长度以进行预剥离得到预剥离长度M的贴膜，在所述第一压辊210进入压紧状态后，所述复合料带80继续被送入所述剥离机构100进行进一步的剥离得到所述预定长度L的剩余长度L-M的贴膜。所述预剥离长度M大于等于所述剥离边缘120到第一压辊210的正下方的距离。所述半切装置500在所述复合料带预剥离完毕后，对所述复合料带80上的贴膜82进行切割，所述半切装置500至所述长度调节装置600的切缝传感器610之间的复合料带的长度与预剥离长度M的和等于所述预定长度L。由于在所述 第一压辊210进入压紧状态前，所述复合料带80被送入所述剥离机构100进行预剥离得到预剥离长度M的贴膜，这样在进入压紧状态时，所述第一压辊210就能够直接压住预剥离长度M的贴膜，从而可以正常的开启贴膜段与所述引线区的贴合过程。而如果在所述第一压辊210进入压紧状态前，所述复合料带80不进行预剥离，那么剥离后的贴膜进入第一压辊210和导电薄膜5的引线区之间时有时可能出现卷边的情况，进而容易导致贴膜失败。
在一个具体实施方式中：例如，需要贴50mm长度(即L＝50mm)的贴膜段，调节所述长度调节装置600的位置，使其所指的刻度为45mm(其中5mm为预剥离长度M，需要扣除)，驱动所述复合料带80由放料盘310向所述剥离机构100运动，此时所述贴膜组件基体700不下压，进行预剥离，预剥离长度M为5mm，即回料驱动装置440先走5mm，当所述导电薄膜5的引线区运动至指定位置后，贴膜组件基体驱动装置800带动所述贴膜组件基体700下压，此时回料驱动装置440的速度与导电薄膜5的传送速度同步，压辊驱动装置221带动第二压辊220也下压，进行贴膜的工作，此时后续贴膜的长度为45mm，当所述长度调节装置600上的切缝传感器610检测到复合料带上的切缝时，贴膜组件基体驱动装置800带动所述贴膜组件基体700抬起，此时第二压辊220仍下压，当第二压辊220贴完最后的5mm后，第二压辊220也抬起，循环上述步骤。
在一个改变的实施例中，在将所述复合料带80放置于所述放料盘310之前，所述复合料带80中的贴膜82就已经提前被切断成预定长度L的贴膜段，此时所述贴膜组件10也可以不设置所述半切装置500。在这个实施例中，所述切缝传感器610仍然需要正常的发挥作用，所述切缝传感器610在其感应到切缝时暂停将所述复合料带80送入所述剥离机构100，另外，控制所述贴膜组件基体700从下压位置回复至所述初始位置。
可见，基于所述切缝传感器610感应得到的切缝信号，来确定暂停所述上料机构300的上料和/或所述回料机构400的收料的时机，以及控制所述贴膜组件基体700从下压位置回复至所述初始位置的时机。基于所述贴膜位置定位装置30定位得到的所述导电薄膜5的引线区的纵向位置，来确定启动所述上料机构300的上料和/或所述回料机构400的收料的时机，以及控制所述贴膜组件基体700从所述初始位置进入下压位置的时机。
在一个可以替换的实施例中，所述压辊组件200也可以只包括一个压辊，比如第一压辊210或第二压辊220，在所述压辊组件200包括一个压辊时，该压辊需要将需要贴的贴膜段82n都辊压后才能够从压紧状态回复至初始状态，此时所述压辊可以与剥离机构100同步在压紧状态和初始状态之前切换，也可以异步在压紧状态和初始状态之前切换。
在一个改变的实施例中，所述上料机构300和所述回料机构400也可以采用其他结构形式，比如，所述导向辊410，320的个数和位置都可以根据需要来调整，所述放料盘310也可以采用其他放料结构，所述回料盘430可以采用其他现有回料结构。实际上，只要所述上料机构300能够将复合薄膜80传送至所述剥离机构100，只要所述回料机构400能够将基膜81回收，只要所述上料机构300和/或所述回料机构400能够驱动所述复合薄膜80和所述基膜81运动即可。
在一个改变的实施例中，也可以不设置所述长度调节装置600，此时所述贴膜段82n的长度可能是固定的，而不是可以调节的，这在有些定制的应用中完全是可以满足需求的。不过所述长度调节装置600中的切缝传感器610还是需要的，不过此时切缝传感器610就不再属于所述长度调节装置600了。
在另一个改变的实施例中，所述剥离机构100、辊压组件200、上料机构300、回料机构400、半切装置500、长度调节装置600可以相互独立设置，而不一定均设置于所述贴膜组件基体700上。根据应用的需要，所述剥离机构100和第一压辊210也可以不与所述贴膜组件基体700同步运动，而可以具有自己的独立的驱动装置，这样所述剥离机构100和第一压辊210可以不同步运动，而是根据需要看是否是需要同步运动，还是需要异步运动。
根据本发明的另一个方面，本发明还可以提供一种基于贴膜设备的贴膜方法。图13示出了本发明中的贴膜设备的贴膜方法1300的流程示意图。如图13所示的，所述方法1300包括如下步骤：
步骤1310，所述运输平台40承载所述导电薄膜5向前运动。
步骤1320，在所述导电薄膜5运动至指定位置时，所述辊压组件200从初始状态进入压紧状态；具体的，基于所述贴膜位置定位装置20定位得到的所述引线区51的纵向位置、所述导电薄膜5的运动速度确定所述导电薄膜5是否运动至指定位置。
步骤1330，驱动所述复合料带80从所述上料机构300沿所述剥离机构本体110的第一导引面111朝向所述剥离边缘120运动。
步骤1340，所述复合料带80在所述剥离边缘被分离成位于靠近剥离机构本体一侧的基膜81和位于远离所述剥离机构本体一侧的贴膜82。
步骤1350，所述基膜81翻过所述剥离边缘120后被驱动的沿第二导引面112远离所述剥离边缘运动，最终所述基膜被传送至所述回料机构400。优选的，所述复合料带80被所述上料机构和/或所述回料机构驱动的与所述运输平台40上的导电薄膜5同步运动，这样贴膜效果好，贴膜平整、无气泡。
步骤1360，所述辊压组件200在压紧状态将分离的贴膜82辊压于所述导电薄膜5的引线区上。
优选的，在所述复合料带80被送入所述剥离机构100前，将所述复合料带82上的贴膜切断成预定长度的贴膜段82n，每次贴膜时将一个贴膜段82n贴附于所述导电薄膜5的引线区上。更为优选的，在所述第一压辊210进入压紧状态前，所述复合料带80被送入所述剥离机构100预剥离长度以进行预剥离得到预剥离长度的贴膜，在所述第一压辊210进入压紧状态后，所述复合料带80继续被送入所述剥离机构100进行进一步的剥离得到所述预定长度L的剩余长度的贴膜段82n。
为了简单，所述贴膜方法1300的具体实现可以参考所述贴膜装置的相关描述，这里就不再重复了。
在一个实施例中，本专利所述设备可以用于生产如下一款产品，其产品结构与基本生产工艺如下。
