本申请涉及涂敷层结合力测试技术领域,特别是涉及一种表面涂敷层结合力检测系统、装置、方法、及镀膜设备。
集流体是锂离子电池不可或缺的电极材料之一,具有承载活性物质和收集微电流的重要功能。复合集流体集成了轻薄化、高安全集流的特征,近年来被广泛研究。通常地,复合集流体采取在高分子基材上形成金属涂敷层制备得到。对于复合集流体,需要对其金属涂敷层与基材之间结合力进行定性测试。目前的测试设备大多采取局部抽样检测,检测结果无法覆盖全产品,检测结果可靠性较低。
发明内容
鉴于上述问题,本申请提供一种表面涂敷层结合力检测系统、装置、方法、镀膜设备及电池生产系统,能够对获得代表镀膜件大部分区域的涂敷层结合力检测结果,检测可靠性较高的问题。
第一方面,本申请提供了一种表面涂敷层结合力检测系统,包括分切机构、第一收卷机构和表面涂敷层结合力检测装置。分切机构用于分切待检镀膜件,以得到成品镀膜件和测试镀膜件。第一收卷机构用于收卷成品镀膜件。表面涂敷层结合力检测装置包括第二收卷机构、剥离机构和检测机构,第二收卷机构用于收卷测试镀膜件,剥离机构用于引导测试镀膜件走带至第二收卷机构,且能够对途经自身的测试镀膜件执行涂敷层剥离操作,检测机构用于获取表征测试镀膜件的涂敷层结合力是否异常的涂敷层剥离结果。
本申请实施例的技术方案中,对待检镀膜件的涂敷层结合力进行检测时,利用分切机构对待检镀膜件分切得到成品镀膜件和测试镀膜件,且在分切过程中,利用第一收卷机构收卷成品镀膜件,并利用第二收卷机构收卷测试镀膜件。在测试镀膜件走带至第二收卷机构的过程中,利用剥离机构对测试镀膜件执行涂敷层剥离操作,利用检测机构获取测试镀膜件的涂敷层剥离结果。
由于测试镀膜件和成品镀膜件由同一待检镀膜件分切而得,测试镀膜件的检测结果适
于成品镀膜件。而且,测试镀膜件和成品镀膜件分别连续走带至第一收卷机构和第二收卷机构,剥离机构可以对测试镀膜件的多个部位测试,测试范围基本能够覆盖全部测试镀膜件,进而可以得到测试镀膜件大部分区域的涂敷层剥离结果,如此相当于实现了成品镀膜件的绝大部分区域的表面涂敷层结合力检测。与现有抽样检测相比,本申请实施例提供的技术方案,基本可以实现待检镀膜件在其长度方向上各处的表面涂敷层结合力检测,检测涵盖范围广,检测结果更能够代表产品的实际情况,检测可靠性更高。
在一些实施例中,表面涂敷层结合力检测装置还包括控制器和标记机构,控制器与标记机构和检测机构通讯连接,控制器用于根据涂敷层剥离结果控制标记机构对成品镀膜件执行标记操作。如此,表面涂敷层结合力检测系统还可以在涂敷层结合力不满足要求时,在成品镀膜件上的相应位置进行标记,以便于后续识别成品镀膜件中涂敷层结合力不合格的部分,方便相关人员将涂敷层结合力不合格的部分切除,既可以降低不合格产品被使用导致产品质量问题,也可以提高成品镀膜件的利用率,降低浪费。
在一些实施例中,剥离机构包括第一引导压辊对和剥离压辊对,第一引导压辊对和剥离压辊对布置于测试镀膜件的走带路径上,且剥离压辊对位于第一引导压辊对和第二收卷机构之间。第一引导压辊对的辊面线速度被配置为与第一收卷机构的辊面线速度相等,剥离压辊对的辊面线速度被配置为与第一引导压辊对的辊面线速度不等。此时,第一引导压辊对将测试镀膜件输送至第二收卷机构,同时利用剥离压辊对对测试镀膜件连续性的执行涂敷层剥离操作,涂敷层剥离效果较好,且结构简单,成本较低,进而可实现检测机构连续性的获取涂敷层剥离结果,使得检测结果覆盖更大的产品范围,检测可靠性更高。
在一些实施例中,剥离压辊对包括拉伸压辊对,拉伸压辊对的辊面线速度被配置为大于第一引导压辊对的辊面线速度。此时,通过拉伸压辊对在测试镀膜件的涂敷层表面作用拉力,拉扯涂敷层脱离基材层,只要合理控制拉伸压辊对的辊面线速度即可,其结构简单,易于调整剥离力。
在一些实施例中,拉伸压辊对相对第一引导压辊对的线速度增长率δ1与测试镀膜件的基材层的断裂伸长率δ2满足:20%≤δ1/δ2≤90%。当δ1/δ2在上述范围内取值时,不仅能够降低基材层被拉断裂的概率,而且还可以对涂覆层上作用较大的拉力,以使得结合力不满足要求的涂覆层可被顺利拉断。
在一些实施例中,剥离压辊对包括摩擦压辊对,沿测试镀膜件的走带路径,摩擦压辊对位于拉伸压辊对和第二收卷机构之间。摩擦压辊对的辊面线速度被配置为与拉伸压辊对的辊面线速度不等,且第二收卷机构的辊面线速度被配置为与拉伸压辊对的辊面线速度相等。由于拉伸压辊对的辊面线速度与第二收卷机构的辊面线速度相等,而摩擦压辊对的辊面线速度与拉伸压辊对的辊面线速度不等,在测试镀膜件经拉伸压辊对拉扯起皮后,经过摩擦压辊对时,在摩擦压辊对的摩擦下,起皮的涂敷层更加容易从基材上脱落,如此,控制器在根据
检测机构获取的涂敷层剥离结果时,检测机构的检测准确性更高。
在一些实施例中,表面涂敷层结合力检测装置还包括粉末收集机构,粉末收集机构位于拉伸压辊对和摩擦压辊对之间。此时,利用粉末收集机构收集从基材层剥离的涂敷层粉末,可以降低脱落的涂敷层对环境的污染。
在一些实施例中,剥离机构还包括第二引导压辊对,第二引导压辊对位于测试镀膜件的走带路径上,且第一引导压辊对位于第二引导压辊对和剥离压辊对之间,第二引导压辊对的辊面线速度被配置为与第一引导压辊对的辊面线速度相同。此时,第一区域可为测试镀膜件提供与成品镀膜件走带速度相同的走带区域,通过第一区域可以缓存一定长度的测试镀膜件,使得测量镀膜件途经第一区域时,其涂敷层不会受到剥离压辊对的作用,可以起到缓冲作用,避免剥离压辊对的作用力传递至分切机构,影响待检镀膜件的走带以及分切。
在一些实施例中,检测机构包括光线发射器和光线收集器,光线发射器和光线收集器被配置为相匹配的布置于测试镀膜件的相背两侧。此时,利用光线发射器与光线收集器配合实现检测机构对涂敷层剥离结果的检测,检测结果可靠,且成本较低。
在一些实施例中,检测机构布置在剥离机构和第二收卷机构之间。也就是说,检测机构可以直接根据被剥离压辊对执行涂敷层剥离操作的测试镀膜件来获取涂敷层剥离结果,可简化表面涂敷层结合力检测装置的整体结构。
第二方面,本申请实施例提供了一种表面涂敷层结合力检测装置,用于测试镀膜件,该表面涂敷层结合力检测装置包括第二收卷机构、剥离机构和检测机构,第二收卷机构用于收卷测试镀膜件,剥离机构用于引导测试镀膜件走带至第二收卷机构,且能够对途经自身的测试镀膜件执行涂敷层剥离操作。检测机构位于剥离机构和第二收卷机构之间,用于获取表征测试镀膜件的涂敷层结合力是否异常的涂敷层剥离结果。
该表面涂敷层结合力检测装置,用于对测试镀膜件的涂敷层结合力进行检测。测试镀膜件在第二收卷机构和剥离机构的引导下持续走带,剥离机构可以对测试镀膜件的多个部位的执行涂敷层剥离操作,且配合检测机构获取测试镀膜件在走带方向上的多个部位的涂敷层剥离结果,如此适应于长度较大的测试镀膜件的表面涂敷层结合力检测。
第三方面,本申请实施例提供了表面涂敷层结合力检测方法,包括:
调用分切机构对走带中的待检镀膜件进行分切,得到成品镀膜件和测试镀膜件;
调用第一收卷机构收卷成品镀膜件,并调用第二收卷机构收卷测试镀膜件;
在测试镀膜件走带至第二收卷机构的过程中,调用剥离机构对测试镀膜件执行涂敷层剥离操作,并调用检测机构获取表征测试镀膜件的涂敷层结合力是否异常的涂敷层剥离结果。
该表面涂敷层结合力检测方法,通过剥离机构可对测试镀膜件的多个部位执行涂敷层剥离操作,检测机构可获取测试镀膜件多个部位的检测结果,因此检测结果适应于成品镀膜件,相当于实现了成品镀膜件的绝大部分区域的表面涂敷层结合力检测。与现有抽样检测相
比,有助于提高待检镀膜件的检测范围广,以及提高待检镀膜件的检测可靠性。
在一些实施例中,表面涂敷层结合力检测方法还包括:
根据涂敷层剥离结果,调用标记机构在成品镀膜件走带至第一收卷机构的过程中,对所述成品镀膜件进行标记。
此时,表面涂敷层结合力检测系统还可以根据涂敷层结合力结果,在成品镀膜件上进行标记,以便于后续识别成品镀膜件中涂敷层结合力不合格的部分,方便相关人员将涂敷层结合力不合格的部分切除,既可以降低不合格产品被使用导致产品质量问题,也可以提高成品镀膜件的利用率,降低浪费。
第四方面,本申请提供了一种镀膜设备,其包括上述实施例中的表面涂敷层结合力检测系统。镀膜设备还包括镀膜机构和放卷机构,两者均位于基材的走带路径上,放卷机构用于放卷基材,镀膜机构用于对基材表面执行镀膜操作,以得到待检镀膜件。
第五方面,本申请提供了一种电池生产系统,包括上述实施例中的镀膜设备。

锂电池的极片制备需要用到集流体,集流体用于涂覆活性材料,并将活性材料产生的电流汇集输出、将外部(如电池单体的电极端子)电流输入给活性材料。因此,集流体通常要求电导率较好,电化学稳定性好,机械强度高。铜箔和铝箔因容易加工、力学强度和成本等因素适宜,被广泛用作极片的集流体。然而,铜箔/铝箔这种纯金属的集流体,重量较大,不利于实现电池的轻量化。复合集流体集成了轻薄化、高安全集流的特征,近年来被广泛研究。通常地,复合集流体采取在高分子基材上形成金属涂敷层制备得到。
对于在基材上形成涂敷层的产品,通常需要对其涂敷层与基材的结合力进行测试,以确保产品质量可靠。目前,对于涂敷层与基材的结合力的涂敷层结合力测试设备大多采取局部抽样检测(即将待检产品的局部作为样品进行检测),其检测结果仅能够对局部样品进行保证,无法涵盖到产品的全部区域,若将局部样品的检测结果作为整个产品的检测结果,容易出现与产品实际情况不相符,检测结果可靠性较低。
基于此,为了提高产品涂敷层结合力的检测结果可靠性,本申请实施例设计一种表面涂敷层结合力检测系统,用于检测涂敷层与基材的结合力异常与否。在一些示例中,通过将待检镀膜件进行分切得到成品镀膜件和测试镀膜件,成品镀膜件和测试镀膜件收卷于不同的收卷机构,在测试镀膜件走带至收卷机构的过程中,对测试镀膜件执行涂敷层剥离操作,并获取其涂敷层剥离结果。其涂敷层剥离结果可用于判断涂敷层与基材的结合力异常与否。
此时,可根据该涂敷层剥离结果来判断测试镀膜件的涂敷层结合力异常与否,由于测试镀膜件和成品镀膜件来自于同一待检镀膜件,测试镀膜件的检测结果适应成品镀膜件的涂敷层结合力情况,且能够反映成品镀膜件在其走带方向上各处的涂敷层结合力情况,如此得到的检测结果能够基本涵盖成品镀膜件的全部区域,其检测结果更能够代表产品的实际情况,检测可靠性较高。
本申请实施例提及的待检镀膜件,是在基材上覆设涂敷层后得到的带状结构。其中,涂敷层可以但不限于通过电镀、热浸镀、喷涂、化学镀、气相沉积、涂布等手段覆设在基材上。图1为根据一个或多个实施例的待检镀膜件的结构示意图。
请参照图1,在待检镀膜件D1的基材层02的厚度方向上至少一侧覆设有涂敷层01。该涂敷层01可以但不限于是金属层、正极活性材料层、负极活性材料层,该基材层02可以但不限于是高分子材料层、金属层,其中,金属层可以但不限于铜金属层、铝金属层,高分子材料层可以但不限于包括聚丙烯、聚酯、聚乙烯中的一种或多种。在一实施例中,待检镀膜件D1是由高层子材料层与金属层复合形成复合集流体,可应用于极片的制备。
本申请实施例中提及的表面涂敷层结合力检测系统,用于对待检镀膜件上涂敷层的结合力异常与否进行检测。本申请实施例中公开的镀膜设备包括该表面涂敷层结合力检测系统、镀膜设备和放卷机构。其中,放卷机构用于放卷基材,镀膜设备用于在基材的走带过程中,对基材表面镀设涂敷层,以得到待检镀膜件。而后,由表面涂敷层结合力检测系统对待
检镀膜件进行分切、涂敷层结合力检测以及回收收卷,在测试镀膜件的涂敷层剥离结果表明涂敷层结合力较好时,其得到的成品镀膜件为良品,可以用于后续生产使用。其中,镀膜机构可以但不限于是蒸镀机构、溅射机构等,本领域技术人员可以进行常规选择。
本申请实施例中提及的电池生产系统,包括本申请实施例中提及的镀膜设备,该镀膜设备可以用于复合集流体、极片等具有涂敷层结构的产品生产。
下面对本申请实施例中提供的表面涂敷层结合力检测系统100作详细介绍。
图2为根据一个或多个实施例的表面涂敷层结合力检测系统100的组成示意图。
根据本申请的一个或多个实施例,请参照图2,本申请实施例提供的表面涂敷层结合力检测系统100包括分切机构10、第一收卷机构20和表面涂敷层结合力检测装置30。分切机构10用于分切待检镀膜件D1,以得到成品镀膜件D11和测试镀膜件D12。第一收卷机构20用于收卷成品镀膜件D11。表面涂敷层结合力检测装置30包括第二收卷机构31、剥离机构32和检测机构33,第二收卷机构31用于收卷测试镀膜件D12,剥离机构32用于引导测试镀膜件D12走带至第二收卷机构31,且能够对途经自身的测试镀膜件D12执行涂敷层剥离操作,检测机构33用于获取表征测试镀膜件D12的涂敷层结合力是否异常的涂敷层剥离结果。
待检镀膜件D1通常呈带状,其长度方向上的尺寸大于其宽度方向上的尺寸。在检测过程中,待检镀膜件D1被输送至分切机构10处。在一些情形下,待检镀膜件D1可以呈卷状,并通过放卷装置放卷、并走带至分切机构10处。在另一些情形下,待检镀膜件D1可以在加工成型过程中走带至分切机构10处。其中,待检镀膜件D1的走带可以利用若干过辊引导实现。
分切机构10用于沿待检镀膜件D1的长度方向(与待检镀膜件D1的走带方向相同)进行切割,将待检镀膜件D1分割得到在其宽度方向上相邻设置的成品镀膜件D11和测试镀膜件D12。测试镀膜件D12是用于进行涂敷层结合力测试的镀膜件部分,成品镀膜件D11是能够作为成品使用的镀膜件部分。由于成品镀膜件D11与测试镀膜件D12来自于同一待检镀膜件D1,测试镀膜件D12的检测结果适用成品镀膜件D11,即可通过测试镀膜件D12的检测结果来判断成品镀膜件D11的涂敷层结合力情况。
由于测试镀膜件D12经检测后无法再利用,测试镀膜件D12属于待检镀膜件D1的测试损耗。为提高待检镀膜件D1的利用率,测试镀膜件D12的宽度通常小于成品镀膜件D11的宽度。在一实施例中,测试镀膜件D12的宽度选值为1cm-2cm,如1.2cm、1.5cm、1.8cm等。此时,测试镀膜件D12具有一定的宽度满足测试所需宽度要求,且待检镀膜件D1的损耗较小。
分切机构10的具体构造有多种,可以进行常规选择。通常地,分切机构10包括切刀。切刀可以保持不动,在待检镀膜件D1经过切刀时,对待检镀膜件D1进行切割。切刀还可
以设计为可转动,切刀能够绕平行待检镀膜件D1的宽度方向的方向自转,在自转的过程中切割待检镀膜件D1。当然,分切机构10还可以包括驱动机构,驱动机构驱动切刀转动。
在一些情形下,分切机构10可以包括一把切刀,通过该把切刀将待检镀膜件D1分割得到一条成品镀膜件D11和一条测试镀膜件D12。在另一些情形下,分切机构10还可以包括多把切刀,通过多把切刀将待检镀膜件D1分割得到至少一条成品镀膜件D11和至少一条测试镀膜件D12。
例如,在一些情形下,切刀包括两把,两把切刀沿待检镀膜件D1的宽度方向间隔布置,两条切刀将待检镀膜件D1分割得到位于两端的两条测试镀膜件D12和位于中间的一条成品镀膜件D11,此时两条测试镀膜件D12的检测结果均可以用于反映成品镀膜件D11的涂敷层结合力情况,可以有效测试待检镀膜件D1的涂敷层结合力分布是否均匀,测试结构更加准确可靠。
第一收卷机构20和第二收卷机构31分别用于收卷成品镀膜件D11和测试镀膜件D12。可理解地,第一收卷机构20收卷的是完好的成品镀膜件D11,第二收卷机构31收卷的是经涂敷层剥离操作之后的测试镀膜件D12。第一收卷机构20和第二收卷机构31通常包括收卷辊以及驱动收卷辊转动的动力机构。第一收卷机构20和第二收卷机构31的具体结构可以进行常规选择,在此不赘述。
剥离机构32布置在测试镀膜件D12的走带路径上,能够引导测试镀膜件D12朝向第二收卷机构31走带。剥离机构32在引导测试镀膜件D12走带的过程中,还可以对测试镀膜件D12执行涂敷层剥离操作。涂敷层剥离操作是指能够将涂敷层01从基材层02上剥离的操作,在一些示例中,是将结合力异常的涂敷层01从基材层02上剥离的操作,在被执行涂敷层剥离操作后,涂敷层01可以停留在基材层02上且与基材层02之间基本无结合,涂敷层01也可从基材层02处直接脱落。可以理解地,剥离机构32向涂敷层01所施加的剥离力度是有设计的。在设计的剥离力度下,若涂敷层01从基材层02上剥离、脱落的程度较大,说明涂敷层01的结合力不满足目标要求,即涂敷层01的结合力不足。反之,在设计的剥离力度下,若涂敷层01从基材层02上剥离、脱落的程度较小甚至不剥离、不脱落,说明涂敷层01的结合力满足目标要求,即涂敷层01的结合力很好。
检测机构33用于获取途经自身的测试镀膜件D12的涂敷层剥离结果,该涂敷层剥离结果用于表征测试镀膜件D12的涂敷层结合力是否异常。以检测机构33根据被执行涂敷层剥离操作后的测试镀膜件D12获取涂敷层剥离结构为例,当被执行涂敷层剥离操作后的测试镀膜件D12上的涂敷层脱落,则检测机构33获取的涂敷层剥离结果表征测试镀膜件D12的涂敷层结合力异常。当被执行涂敷层剥离操作后的测试镀膜件D12上的涂敷层未脱落,则检测机构33获取的涂敷层剥离结果表征测试镀膜件D12的涂敷层结合力正常。
需要说明的是,本申请实施例中所提及的“涂敷层结合力”是指涂敷层01与基材层
02之间的结合力。
检测机构33的布置位置可根据剥离机构32的类型作调整。通常地,无论剥离机构32的具体构造如何,检测机构33均可沿测试镀膜件D12的走带路径布置在剥离机构32和第二收卷机构31之间,即,测试镀膜件D12在走带至第二收卷机构31的过程中,经过剥离机构32并被剥离机构32多次执行涂敷层剥离操作,而后经过检测机构33并被检测机构33多次获取涂敷层剥离结果,最后收卷到第二收卷机构31处。当然,在其他情形下,若剥离机构32通过胶带对测试镀膜件D12执行涂敷层剥离操作,则检测机构33也可以布置在被撕的胶带的移动路径上。
检测机构33获取涂敷层剥离结果的手段有多种。例如,检测机构33通过视觉检测来实现。在一些示例中,检测机构33可以包括拍摄部和图像分析部,拍摄部拍摄测试镀膜件D12的图像数据,图像分析部分析图像数据,并根据图像数据分析确定测试镀膜件D12的涂敷层剥离程度。当然,检测机构33还可以采取诸如下述实施例中提及的手段等其他方式来实现对涂敷层剥离结果的获取。
上述表面涂敷层结合力检测系统100,对待检镀膜件D1的涂敷层结合力是否异常进行检测时,利用分切机构10对待检镀膜件D1分切得到成品镀膜件D11和测试镀膜件D12,且在分切过程中,利用第一收卷机构20收卷成品镀膜件D11,并利用第二收卷机构31收卷测试镀膜件D12。在测试镀膜件D12走带至第二收卷机构31的过程中,利用剥离机构32对测试镀膜件D12执行涂敷层剥离操作,最后利用检测机构33获取测试镀膜件D12的涂敷层剥离结果。
由于测试镀膜件D12和成品镀膜件D11由同一待检镀膜件D1分切而得,测试镀膜件D12的检测结果适于成品镀膜件D11。而且,测试镀膜件D12和成品镀膜件D11分别连续走带至第一收卷机构20和第二收卷机构31,剥离机构32可以对测试镀膜件D12的多个部位进行测试,测试范围基本能够覆盖全部测试镀膜件D12,进而可以得到测试镀膜件D12大部分区域的涂敷层剥离结果,如此相当于实现了成品镀膜件D11的绝大部分区域的表面涂敷层结合力检测。与现有抽样检测相比,本申请实施例提供的技术方案,基本可以实现待检镀膜件D1在其长度方向上各处的表面涂敷层结合力检测,检测涵盖范围广,其检测结果更能够代表产品的实际情况,检测可靠性较高。
在本申请实施例中,测试镀膜件D12的“多个部位”是指在测试镀膜件D12的长度方向上连续布置或者间隔布置的多个区域。
在一些实施例中,请参照图2,表面涂敷层结合力检测装置30还包括控制器(未图示)和标记机构34,控制器与标记机构34和检测机构33通讯连接,控制器用于根据涂敷层剥离结果控制标记机构34对成品镀膜件D11执行标记操作。
控制器(未图示)是具有数据处理功能的器件/组件/装置。控制器可以包括中央处理器、微处理器、嵌入式单片机。控制器可以是笔记本电脑、工控机、移动终端(如手机、智能手表)、服务器等。
控制器可以与检测机构33集成于一体,控制器还可以与标记机构34集成于一体。控制器也可以独立于检测机构33和标记机构34而存在。
标记机构34是指可以在镀膜件上进行标记的机构,其标记的方式可以但不限于是粘贴标签、贴边剪标记缺口、压印标记压花等。关于标记机构34的具体标记形式及其构造可以进行常规选择和设计。在实际应用时,标记机构34靠近成品镀膜件D11布置,具体可以地,标记机构34布置在成品镀膜件D11自分切机构10走带至第一收卷机构20的走带路径的边缘处。
控制器可以根据涂敷层剥离结果控制标记机构34对成品镀膜件D11执行标记操作。容易理解地,检测机构33逐次获取测试镀膜件D12的涂敷层剥离结果,且间隔时间越短检测精度越高。
控制器可以在每次获取检测机构33的剥离结合力结果时控制标记机构34对成品镀膜件D11执行相应的标记操作。在一些示例中,控制器的控制方法可以包括如下步骤:获取当前涂敷层剥离结果,识别当前涂敷层剥离结果的类型;若当前涂敷层剥离结果的类型为异常,则控制标记机构34执行第一标记操作;若当前涂敷层剥离结果的类型为正常,则控制标记机构34执行第二标记操作。标记机构34在执行第一标记操作和第二标记操作时,可以通过贴设不同颜色的标签来识别。
控制器还可以仅在涂敷层剥离结果显示剥离结合力不足的起点位置和终点位置控制标记操作执行相应的标记操作。在一些示例中,控制器的控制方法可以包括如下步骤:获取当前涂敷层剥离结果,识别当前涂敷层剥离结果的类型;若当前涂敷层剥离结果的类型为异常,获取上一涂敷层剥离结果的类型;若上一涂敷层剥离结果的类型为正常,则控制标记机构34执行异常起点标记操作;若当前涂敷层剥离结果的类型为正常,获取上一涂敷层剥离结果的类型;若上一涂敷层剥离结果的类型为异常,则控制标记机构34执行异常终点标记操作。此时,标记机构34仅需要在涂敷层结合力异常的区间端点位置处进行标记,标记机构34操作更加简单,且可降低因标记对成品镀膜件D11的损坏几率。其中,标记机构34在执行异常起点标记操作和异常终点标记操作时,可以通过贴设不同颜色的标签来识别。
通常地,检测机构33设置于第一固定位置,标记机构34设置于第二固定位置,且沿成品镀膜件D11的走带路径布置。
以检测机构33对应被执行剥离操作后的测试镀膜件D12的位置设置为例进行说明。检测机构33每次获得的是被执行剥离操作后的测试镀膜件D12中途经第一固定位置的部分(定义为第一长度部分)的涂敷层剥离结果,若第一长度部分的涂敷层剥离结果表示涂敷层
结合力异常,说明与该第一长度部分相对应的成品镀膜件D11中的第二长度部分(第一长度部分在测试镀膜件D12长度方向上的位置与第二长度部分在成品镀膜件D11长度方向上的位置基本一致)的涂敷层结合力异常,则标记机构34可对途经第二固定位置的第二长度部分执行相应的标记操作。
反之,若第一长度部分的涂敷层剥离结果表示涂敷层结合力正常,说明与该第一长度部分相对应的成品镀膜件D11中的第二长度部分的涂敷层结合力正常,则标记机构34可对途经第二固定位置的第二长度部分执行相应的标记操作。
在进行设计时,在第一长度部分经过检测机构33的第一固定位置后的一定时间内(该时间通常由检测机构33在获得涂敷层剥离结果后至标记机构34根据该次涂敷层剥离结果执行标记操作之间的时间差来决定),需要控制第二长度部分经过标记机构34的第二固定位置处,以使得标记机构34在执行标记操作时可以对第二长度部分打标记。此处需要考虑到测试镀膜件D12的走带速度和成品镀膜件D11的走带速度之间的关系,本领域技术人员可以通过合理的数学设计得以实现,而本申请实施例中对于具体如何进行设计不进行详细阐述。
如此,表面涂敷层结合力检测系统100还可以在涂敷层结合力不满足要求时,在成品镀膜件D11上的相应位置进行标记,以便于后续识别成品镀膜件D11中涂敷层结合力不合格的部分,方便相关人员将涂敷层结合力不合格的部分切除,既可以降低不合格产品被使用导致产品质量问题,也可以提高成品镀膜件D11的利用率,降低浪费。
当然,在其他实施例中,若不设置标记机构34,也可以由计算机设备根据检测机构33获取的涂敷层剥离结果分析出涂敷层结合力正常以及涂敷层结合力不足的成品镀膜件D11的位置数据,以便于相关人员去除不合格的部分。
图3为根据一个或多个实施例的表面涂敷层结合力检测装置30的组成示意图。
在一些实施例中,请参照图3,剥离机构32包括第一引导压辊对32a和剥离压辊对32c,第一引导压辊对32a和剥离压辊对32c布置于测试镀膜件D12的走带路径上,且剥离压辊对32c位于第一引导压辊对32a和第二收卷机构31之间。第一引导压辊对32a的辊面线速度被配置为与第一收卷机构20的辊面线速度相等,剥离压辊对32c的辊面线速度被配置为与第一引导压辊对32a的辊面线速度不等。
在本申请实施例中,各“压辊对”均包括相对布置的两个压辊,该相对布置的两个压辊间隔形成有辊压间隙,测试镀膜件D12通过该辊压间隙时,与该两个压辊接触,并在该两个压辊的推动下走带。可理解地,各“压辊对”的两个压辊的辊面线速度相同且旋转方向相反。在图3所述实施例中,各“压辊对”的两个压辊在上下方向上间隔布置。“压辊对”中各压辊可以但不限采用橡胶材质,表面摩擦力较大,可降低测试镀膜件D12打滑程度。
辊面线速度是指辊面上任意一点运动的速度。压辊的转速是指每分钟旋转的圈数,在压辊直径相同的情况下,相同转速的压辊其辊面线速度相同。理论上,辊面线速度与压辊的
转速有如下关系:辊面线速度=辊面长度×转速×π÷60,其中,辊面长度是指压辊与涂敷层的接触的长度,其通常是指压辊的轴向长度,π为圆周率。
第一引导压辊对32a的辊面线速度与第一收卷机构20的辊面线速度相等,即测试镀膜件D12自分切机构10走带至第一引导压辊对32a的走带速度与成品镀膜件D11自分切机构10走带至第一收卷机构20的走带速度一致,如此,测试镀膜件D12和成品镀膜件D11在靠近分切机构10处的速度一致,有利于分切机构10分切待检镀膜件D1。其中,第一收卷机构20的辊面线速度是指其收卷辊的速度。
剥离压辊对32c的辊面线速度与第一引导压辊对32a的辊面线速度不等,则测试镀膜件D12在第一引导压辊对32a和剥离压辊对32c之间的第二区域Q2走带时,剥离压辊对32c能够向测试镀膜件D12作用剥离力,该剥离力可以是阻碍涂敷层01跟随基材层02移动而使得涂敷层01相对基材层02错位的摩擦力,该剥离力也可以是拉动涂敷层01相对基材层02超前移动而使得涂敷层01延展的拉伸力,涂敷层01相对基材层02延伸、错位时会出现起皮、气泡、脱离等异常现象。
此时,第一引导压辊对32a将测试镀膜件D12输送至第二收卷机构31,同时利用剥离压辊对32c对测试镀膜件D12连续性的执行涂敷层剥离操作,涂敷层01剥离效果较好,且结构简单,成本较低,进而可实现检测机构33连续性的获取涂敷层剥离结果,使得检测结果覆盖更大的产品范围,检测可靠性更高。
本申请实施例中提及的“走带路径”是指带状构件(如测试镀膜件C11、成品镀膜件C12、待检镀膜件D1)在外物引导下移动时,所在的移动轨迹。
在一些实施例中,请参照图3,剥离压辊对32c包括拉伸压辊对c1,拉伸压辊对c1的辊面线速度被配置为大于第一引导压辊对32a的辊面线速度。
可理解地,拉伸压辊对c1布置在第一引导压辊对32a和第二收卷机构31之间。拉伸压辊对c1的辊面线速度大于第一引导压辊对32a时,拉伸压辊对c1可对途经第二区域Q2的涂敷层01作用拉力,进而拉动涂敷层01相对基材层02延展,当涂敷层结合力异常,被拉力拉动的涂敷层01容易与基材层02脱离,出现起皮、褶皱、甚至断裂等问题,此时,涂敷层01可能会也可能不会断裂或者可能会/可能不会从基材层02上脱落。
此时,通过拉伸压辊对c1在测试镀膜件D12的涂敷层01表面作用拉力,拉扯涂敷层01脱离基材层02,只要合理控制拉伸压辊对c1的辊面线速度即可,其结构简单,易于调整剥离力。
在一些实施例中,拉伸压辊对c1相对第一引导压辊对32a的线速度增长率δ1与测试镀膜件D12的基材层02的断裂伸长率δ2满足:20%≤δ1/δ2≤90%。
拉伸压辊对c1相对第一引导压辊对32a的线速度增长率δ1是指两者的辊面线速度之间的增长率,在一些示例中,线速度增长率δ1可以采取如下方式计算:δ1=(Vc1-V32a)
/V32a,其中,Vc1为拉伸压辊对c1的辊面线速度,V32a为第一引导压辊对32a的辊面线速度。
断裂伸长率是指物体在被拉伸时断裂前的最大延伸量与初始长度之比。测试镀膜件D12包括基材层02和涂敷在基材层02上的涂敷层01,基材层02的断裂伸长率δ2即为未涂敷涂敷层01前的基材层02的断裂伸长率,不同材质的基材层02其断裂伸长率δ2不同。其中,当基材层02为高分子材料层,其断裂伸长率可以按照GB/T 1040.1-2018《塑料拉伸性能的测定》的标准进行测定。
可理解地,当测试镀膜件D12途径位于第一引导压辊对32a和拉伸压辊对c1之间的第二区域Q2时,拉伸压辊对c1作用的拉力也会对基材层02产生一定的作用,为了避免基材层02被拉断,在设计时,拉伸压辊对c1相对第一引导压辊对32a的线速度增长率δ1应当小于基材层02的断裂伸长率δ2。若基材层02被拉断,则会使得测试镀膜件D12无法连续走带。
在一些示例中,拉伸压辊对c1相对第一引导压辊对32a的线速度增长率δ1与基材层02的断裂伸长率δ2应当满足δ1/δ2的值在20%~90%范围内,例如20%、30%、40%、50%、60%、70%、80%、90%及位于相邻两个数值之间的任一数值。进一步可以是40%~80%。
当δ1/δ2在上述范围内取值时,不仅能够降低基材层02被拉断裂的概率,而且还可以对涂敷层01上作用较大的拉力,以使得结合力不满足要求的涂敷层01可被顺利拉断。
在一些实施例中,请参照图3,剥离压辊对32c包括摩擦压辊对c2,沿测试镀膜件D12的走带路径,摩擦压辊对c2位于拉伸压辊对c1和第二收卷机构31之间。摩擦压辊对c2的辊面线速度被配置为与拉伸压辊对c1的辊面线速度不等,且第二收卷机构31的辊面线速度被配置为与拉伸压辊对c1的辊面线速度相等。
摩擦压辊对c2的辊面线速度可以稍小于或者稍大于拉伸压辊对c1的辊面线速度。
由于拉伸压辊对c1的辊面线速度与第二收卷机构31的辊面线速度相等,而摩擦压辊对c2的辊面线速度与拉伸压辊对c1的辊面线速度不等,在测试镀膜件D12经拉伸压辊对c1拉扯起皮后,涂敷层01可能仍旧支撑在基材层02上,经过摩擦压辊对c2时,在摩擦压辊对c2的摩擦下,起皮的涂敷层01更加容易从基材层02上脱落而直接暴露基材层02,如此,控制器在根据检测机构33获取的涂敷层剥离结果时,检测机构33的检测准确性更高。
当然,在其他实施例中,剥离压辊对32c可以仅包括摩擦压辊对c2,此时,摩擦压辊对c2的辊面线速度与第一引导压辊对32a的辊面线速度不同(稍大或者稍小),摩擦压辊对c2利用摩擦致使涂敷层01脱离基材层02,甚至从基材层02上脱落,此时,第二收卷机构31的辊面线速度可以与第一引导压辊对32a的辊面线速度一致。
在上述实施例中,剥离机构32通过各压辊对的配合实现涂敷层01的剥离。在其他实施例中,剥离机构32还可以采取诸如胶带撕离涂敷层01的方式来对涂敷层01进行剥
离。作为示例地,将在上述实施例中的剥离压辊对32c的辊面线速度设计为与第一引导压辊对32a相同,通过在剥离压辊对32c上设置双面胶,利用双面胶撕离涂敷层01。此外,剥离机构32还可以采取设置铲刀的方式将涂敷层01铲离而实现涂敷层01的剥离,作为示例地,将在上述实施例中的剥离压辊对32c替换为铲刀。
在一些实施例中,请参照图3,表面涂敷层结合力检测装置30还包括粉末收集机构35,粉末收集机构35位于拉伸压辊对c1和摩擦压辊对c2之间。
粉末收集机构35用于从基材层02上收集剥离的涂敷层01。粉末收集机构35可以是负压机构、磁吸附机构、正压吹扫机构等,对于粉末机构的具体构造,本领域技术人员可以进行常规选择,在此不赘述。在一些示例中,拉伸压辊对c1和摩擦压辊对c2之间的区域为第三区域Q3,粉末收集机构35主要收集该第三区域Q3的粉末。
此时,利用粉末收集机构35收集从基材层02剥离的涂敷层01粉末,可以降低脱落的涂敷层01对环境的污染。
在一些实施例中,请参照图3,剥离机构32还包括第二引导压辊对32b,第二引导压辊对32b位于测试镀膜件D12的走带路径上,且第一引导压辊对32a位于第二引导压辊对32b和剥离压辊对32c之间,第二引导压辊对32b的辊面线速度被配置为与第一引导压辊对32a的辊面线速度相同。
第二引导压辊对32b用于引导测试镀膜件D12从分切机构10走带至第一引导压辊对32a处。第二引导压辊对32b的辊面线速度与第一引导压辊对32a的辊面线速度相同,也就是说,第一引导压辊对32a、第二引导压辊对32b和第一收卷机构20的辊面线速度相同。
测试镀膜件D12从第二引导压辊对32b走带至第一引导压辊对32a的过程中,能够与走带至第一收卷机构20的成品镀膜件D11的走带速度相同。定义第一引导压辊对32a和第二引导压辊对32b之间的区域为第一区域Q1。
此时,第一区域Q1可为测试镀膜件D12提供与成品镀膜件D11走带速度相同的走带区域,通过第一区域Q1可以缓存一定长度的测试镀膜件D12,使得测量镀膜件途经第一区域Q1时,其涂敷层01不会受到剥离压辊对32c的作用,可以起到缓冲作用,避免剥离压辊对32c的作用力传递至分切机构10,影响待检镀膜件D1的走带以及分切。
当然,在其他实施例中,在第一引导压辊对32a和第二引导压辊对32b之间还可以设置其他压辊对,该“其他压辊对”与第一引导压辊对32a和第二引导压辊对32b的辊面线速度一致即可。
在一些实施例中,请参照图3,检测机构33布置在剥离机构32和第二收卷机构31之间。也就是说,检测机构33可以直接根据被剥离压辊对32c执行涂敷层剥离操作的测试镀膜件D12来获取涂敷层剥离结果,可简化表面涂敷层结合力检测装置30的整体结构。
当然,在其他实施例中,剥离机构32还可以包括粘胶部(未图示),粘胶部用于粘取从测试镀膜件D12上脱落的涂敷层物质,检测机构33可以通过粘胶部上是否存在涂敷层物质来获取测试镀膜件D12的涂敷层剥离结果。
在一些实施例中,请参照图3,检测机构33包括光线发射器33d和光线收集器33e,光线发射器33d和光线收集器33e被配置为相匹配的布置于测试镀膜件D12的相背两侧。
光线发射器33d与光线收集器33e相匹配,前者用于发射特定光线,后者用于接收该特定光线。“特定光线”可以但不限于是激光、红外光、蓝光等等。
光线发射器33d与光线收集器33e布置在测试镀膜件D12的相背两侧,是指两者布置在测试镀膜件D12在厚度方向上的相背两侧,通常涂敷层01位于测试膜镀膜件该“相背两侧”中的至少一侧。
当经过检测机构33的测试镀膜件D12上的涂敷层01脱落时,光线发射器33d所发射的光线可透过测试镀膜件D12而被光线收集器33e所接收,如此,检测机构33所获取的涂敷层剥离结果可以为光线接收器的光线接收结果。例如,当光线接收器接收到光线时,则向控制器反馈表示涂敷层结合力异常的信息。当光线接收器未接收到光线时,则控制器反馈表示涂敷层结合力良好的信息。进一步地,控制器可以根据光线接收其反馈的信息控制标记机构34执行标记操作。
此时,利用光线发射器33d与光线收集器33e配合实现检测机构33对涂敷层剥离结果的检测,检测结果可靠,且成本较低。
在一些实施例中,请参照图2,表面涂敷层结合力检测系统100还可以包括镀膜件放卷辊40,镀膜件放卷辊40用于放卷待检镀膜件D1。经镀膜件放卷辊40释放的待检镀膜件D1走带至分切机构10处,并被分切机构10分切得到成品镀膜件D11和测试镀膜件D12。此时,表面涂敷层结合力检测系统100适应于待检镀膜件D1被生产成卷后,对待检镀膜件D1进行涂敷层结合力检测。
在本申请的一实施例中,表面涂敷层结合力检测系统100包括分切机构10、第一收卷机构20和表面涂敷层结合力检测装置30,表面涂敷层结合力检测装置30包括标记机构34以及依次布置的第二引导压辊对32b、第一引导压辊对32a、拉伸压辊对c1、摩擦压辊对c2、检测机构33和第二收卷机构31。分切机构10用于对待检镀膜件D1进行分切得到成品镀膜件D11和测试镀膜件D12,成品镀膜件D11收卷到第一收卷机构20,测试镀膜件D12依次经第二引导压辊对32b、第一引导压辊对32a、拉伸压辊对c1、摩擦压辊对c2、检测机构33后收卷到第二收卷机构31。第一引导压辊对32a、第二引导压辊对32b和第一收卷机构20三者的辊面线速度相同,拉伸压辊对c1的辊面线速度大于第一引导压辊对32a的辊面线速度,且摩擦压辊对c2的辊面线速度与第一引导压辊对32a的辊面线速度和拉伸
压辊对c1的辊面线速度均不等,第二收卷机构31的辊面线速度与拉伸压辊对c1的辊面线速度相同。标记机构34对应成品镀膜件D11布置,检测机构33用于获取测试镀膜件D12的涂敷层剥离结果,标记机构34根据涂敷层剥离结果对成品镀膜件D11执行标记操作。
另外,请参照图3,本申请实施例还提供了一种表面涂敷层结合力检测装置30,用于测试镀膜件D12,该表面涂敷层结合力检测装置30包括第二收卷机构31、剥离机构32和检测机构33,第二收卷机构31用于收卷测试镀膜件D12,剥离机构32用于引导测试镀膜件D12走带至第二收卷机构31,且能够对途经自身的测试镀膜件D12执行涂敷层剥离操作。检测机构33用于获取表征测试镀膜件D12涂敷层结合力是否异常的涂敷层剥离结果。
关于第二收卷机构31、剥离机构32和检测机构33的详细介绍,请参照上文记载,在此不赘述。
该表面涂敷层结合力检测装置30,用于对测试镀膜件D12的涂敷层结合力进行检测。测试镀膜件D12在第二收卷机构31和剥离机构32的引导下持续走带,剥离机构32可以对测试镀膜件D12的多个部位执行涂敷层剥离操作,且配合检测机构33可获取测试镀膜件D12在走带方向上的多个部位的涂敷层剥离结果,如此适应于长度较大的测试镀膜件D12的表面涂敷层结合力检测。
而且,该表面涂敷层结合力检测装置30配合分切机构10和第一收卷机构20使用时,因其获取测试镀膜件D12的多个部位的检测结果,相当于实现了成品镀膜件D11的绝大部分区域的表面涂敷层结合力检测,其检测结果更能够代表成品镀膜件D11的实际情况,检测可靠性较高。与现有抽样检测相比,有助于提高待检镀膜件D1的检测范围广,以及提高待检镀膜件D1的检测可靠性。
在一些实施例中,请参照图3,剥离机构32包括第一引导压辊对32a和剥离压辊对32c,第一引导压辊对32a和剥离压辊对32c布置于测试镀膜件D12的走带路径上,且剥离压辊对32c位于第一引导压辊对32a和第二收卷机构31之间。剥离压辊对32c的辊面线速度被配置为与第一引导压辊对32a的辊面线速度不等。
关于剥离压辊对32c、第一引导压辊对32a、第二收卷机构31的介绍参照上文描述,在此不赘述。
第一引导压辊对32a将测试镀膜件D12输送至第二收卷机构31,同时利用剥离压辊对32c对测试镀膜件D12连续性的执行涂敷层剥离操作,涂敷层01剥离效果较好,且结构简单,成本较低,进而可实现检测机构33连续性的获取涂敷层剥离结果,使得检测结果覆盖更大的产品范围,检测可靠性更高。
在一些实施例中,请参照图3,剥离压辊对32c包括拉伸压辊对c1,拉伸压辊对c1的辊面线速度被配置为大于第一引导压辊对32a的辊面线速度。
此时,通过拉伸压辊对c1在测试镀膜件D12的涂敷层01表面作用拉力,拉扯涂
敷层01脱离基材层02,只要合理控制拉伸压辊对c1的辊面线速度即可,其结构简单,易于调整剥离力。
在一些实施例中,请参照图3,剥离压辊对32c包括摩擦压辊对c2,沿测试镀膜件D12的走带路径,摩擦压辊对c2位于拉伸压辊对c1和第二收卷机构31之间。摩擦压辊对c2的辊面线速度被配置为与拉伸压辊对c1的辊面线速度不等,且第二收卷机构31的辊面线速度被配置为与拉伸压辊对c1的辊面线速度相等。
由于拉伸压辊对c1的辊面线速度与第二收卷机构31的辊面线速度相等,而摩擦压辊对c2的辊面线速度与拉伸压辊对c1的辊面线速度不等,在测试镀膜件D12经拉伸压辊对c1拉扯起皮后,经过摩擦压辊对c2时,在摩擦压辊对c2的摩擦下,起皮的涂敷层01更加容易从基材层02上脱落,如此,控制器在根据检测机构33获取的涂敷层剥离结果时,检测机构33的检测准确性更高。
在一些实施例中,请参照图3,表面涂敷层结合力检测装置30还包括粉末收集机构35,粉末收集机构35位于拉伸压辊对c1和摩擦压辊对c2之间。
关于粉末收集机构35的介绍详见上文记载。此时,利用粉末收集机构35收集脱离的涂敷层01粉末,可以降低脱落涂敷层01对环境的污染。
在一些实施例中,请参照图3,剥离机构32还包括第二引导压辊对32b,第二引导压辊对32b位于测试镀膜件D12的走带路径上,且第一引导压辊对32a位于第二引导压辊对32b和剥离压辊对32c之间,第二引导压辊对32b的辊面线速度被配置为与第一引导压辊对32a的辊面线速度相同。
关于第二引导压辊的介绍详见上文记载。此时,第一区域Q1可为测试镀膜件D12提供与成品镀膜件D11走带速度相同的走带区域,通过第一区域Q1可以缓存一定长度的测试镀膜件D12,使得测量镀膜件途经第一区域Q1时,其涂敷层01不会受到剥离压辊对32c的作用,可以起到缓冲作用,避免剥离压辊对32c的作用力传递至分切机构10,影响待检镀膜件D1的走带以及分切。
当然,在其他实施例中,在第一引导压辊对32a和第二引导压辊对32b之间还可以设置其他压辊对,该“其他压辊对”与第一引导压辊对32a和第二引导压辊对32b的辊面线速度一致即可。
在一些实施例中,拉伸压辊对c1相对第一引导压辊对32a的线速度增长率δ1与测试镀膜件D12的基材层02的断裂伸长率δ2满足:20%≤δ1/δ2≤90%。
关于线速度增长率δ1、断裂伸长率δ2的介绍参照上文描述。
当δ1/δ2在上述范围内取值时,不仅能够降低基材层02被拉断裂的概率,而且还可以对涂敷层01上作用较大的拉力,以使得结合力不满足要求的涂敷层01可被顺利拉断。
在一些实施例中,请参照图3,检测机构33布置在剥离机构32和第二收卷机构
31之间。也就是说,检测机构33可以直接根据被剥离压辊对32c执行涂敷层剥离操作的测试镀膜件D12来获取涂敷层剥离结果,可简化表面涂敷层结合力检测装置30的整体结构。
在一些实施例中,请参照图3,检测机构33包括光线发射器33d和光线收集器33e,光线发射器33d和光线收集器33e被配置为相匹配的布置于测试镀膜件D12的相背两侧。
关于光线发射器33d与光线收集器33e的介绍详见上文记载。
此时,利用光线发射器33d与光线收集器33e配合实现检测机构33对涂敷层剥离结果的检测,检测结果可靠,且成本较低。
在一些实施例中,请参照图3,表面涂敷层结合力检测装置30还包括控制器(未图示)和标记机构34,控制器与标记机构34和检测机构33通讯连接,控制器用于根据涂敷层剥离结果控制标记机构34执行标记操作。
关于控制器和标记机构34的介绍详见上文记载,在此不赘述。具体应用时,标记机构34可以但不限用于对成品镀膜件D11执行标记操作。关于成品镀膜件D11的介绍参见上文描述。
此时,表面涂敷层结合力检测系统100还可以在涂敷层结合力不满足要求时,在成品镀膜件D11上的相应位置进行标记,以便于后续识别成品镀膜件D11中涂敷层结合力不合格的部分,方便相关人员将涂敷层结合力不合格的部分切除,既可以降低不合格产品被使用导致产品质量问题,也可以提高成品镀膜件D11的利用率,降低浪费。
需要说明地,该表面涂敷层结合力检测装置30还包括上述实施例中的表面涂敷层结合力检测装置30的全部特征和效果,具体参照上文描述,在此不进行赘述。
需要说明的,当测试镀膜件D12的两侧均具有涂敷层01,可以利用本申请实施例提供的表面涂敷层结合力检测装置30对测试镀膜件D12的两层涂敷层01逐层进行涂敷层结合力检测,也可以利用表面涂敷层结合力检测装置30对两层涂敷层01同时进行表面涂敷层结合力检测。例如,将剥离机构32设置测试镀膜件D12的两侧,以分别对两侧涂敷层01执行涂敷层剥离操作。
另外,请参照图4,图4为根据一个或多个实施例的表面涂敷层结合力检测方法的流程示意图,本申请实施例还提供了一种表面涂敷层结合力检测方法,该表面涂敷层结合力检测方法包括:
S100、调用分切机构10对走带中的待检镀膜件D1进行分切,得到成品镀膜件D11和测试镀膜件D12;
S200、调用第一收卷机构20收卷成品镀膜件D11,并调用第二收卷机构31收卷测试镀膜件D12;
S300、在测试镀膜件D12走带至第二收卷机构31的过程中,调用剥离机构32对
测试镀膜件D12执行涂敷层剥离操作,并调用检测机构33获取表征测试镀膜件D12的涂敷层结合力是否异常的涂敷层剥离结果。
本申请实施例中的表面涂敷层结合力检测方法,可以但不限于应用于如上述的表面涂敷层结合力检测系统100,也可以应用于包含了上述表面涂敷层结合力检测系统100的设备/系统。执行该表面涂敷层结合力检测方法的装置可以但不限于是表面涂敷层结合力检测装置30中的控制器。
在步骤S100中,可以调用分切机构10对待检镀膜件D1进行分切,得到成品镀膜件D11和测试镀膜件D12。通常情况下,待检镀膜件D1呈卷状,且经放卷机构200放卷并在输送机构(如过辊)的输送下朝向分切机构10走带。当然,在其他情况下,待检镀膜件D1也可以在静止状态下被分切机构10分切。
在步骤S200中,可以调用第一收卷机构20和第二收卷机构31分别对成品镀膜件D11和测试镀膜件D12进行收卷。
在步骤S300中,可以调用剥离机构32在测试镀膜件D12走带至第二收卷机构31的过程中,对测试镀膜件D12执行涂敷层剥离操作。而且,在测试镀膜件D12走带过程中,还可以调用检测机构33获取测试镀膜件D12的涂敷层剥离结果。
该表面涂敷层结合力检测方法,通过剥离机构32可对测试镀膜件D12的多个部位执行涂敷层剥离操作,检测机构33可获取测试镀膜件D12多个部位的检测结果,相当于实现了成品镀膜件D11的绝大部分区域的表面涂敷层结合力检测,其检测结构更加能够代表成品镀膜件D11的实际情况,检测可靠性更高。与现有抽样检测相比,有助于提高待检镀膜件D1的检测范围广,以及提高待检镀膜件D1的检测可靠性。
在一些实施例中,请参照图5,图5为根据另一个或多个实施例的表面涂敷层结合力检测方法的流程示意图。表面涂敷层结合力检测方法还包括:
S400、根据涂敷层剥离结果,调用标记机构34在成品镀膜件D11走带至第一收卷机构20的过程中,对所述成品镀膜件D11进行标记。
在一些示例中,控制器在执行S400时,执行下述步骤:S401、获取当前剥离结合力结果,识别当前剥离结合力结果的类型;S402、若当前剥离结合力结果的类型为异常,获取上一剥离结合力结果的类型;S403、若上一剥离结合力结果的类型为正常,则控制标记机构34执行异常起点标记操作;S404、若当前剥离结合力结果的类型为正常,获取上一剥离结合力结果的类型;S405、若上一剥离结合力结果的类型为异常,则控制标记机构34执行异常终点标记操作。
此时,表面涂敷层结合力检测系统100还可以根据涂敷层结合力结果,在成品镀膜件D11上进行标记,以便于后续识别成品镀膜件D11中涂敷层结合力不合格的部分,方便相关人员将涂敷层结合力不合格的部分切除,既可以降低不合格产品被使用导致产品质量
问题,也可以提高成品镀膜件D11的利用率,降低浪费。

放卷机构200通常包括放卷辊,基材D0卷绕在放卷辊上。镀膜设备1000还可包括输送机构,输送机构可以但不限于包括多个过辊,过辊用于引导基材D0走带。镀膜机构300可以是蒸镀机构、溅射机构、气相沉积机构等,可以进行常规选择。
此时,镀膜设备1000将表面涂敷层结合力检测系统100、镀膜机构300等集成于一体,不仅可以实现镀膜件的生产,还可以同步实现镀膜件的涂敷层结合力的连续检测,镀膜设备1000的集成化程度高,而且方便工作人员根据检测结果反哺镀膜过程,以及时调整镀膜工艺。
