在上述技术方案中，通过将辊压机构设置在剥离机构的上游，使得辊压机构将涂料压实后再通过剥离机构剥离遮挡件，由于涂料已经被压实，可以避免剥离机构在剥离遮挡件时将涂料蹭离基材。另外，在剥离遮挡件之前对涂料进行辊压，由于遮挡件还占据着制痕区的位置，可以防止涂料被辊压至制痕区内。
第二方面，本申请实施例还提供了一种叠片制造系统，所述叠片制造系统包括上述的制痕装置。

电池生产过程中，需要对极片进行制痕，但是，现有技术中制痕后的极片制造的电极组件往往性能较差。
发明人经研究发现，现有技术中在极片上制痕是利用激光光束高度聚集性产生的高温烧蚀极片单面(或正反面)的活性物质层，形成一条露基材但不伤基材的刻痕。但是，激光烧蚀活性物质层时，在高温的作用下会产生热影响区，热影响区将影响刻痕两侧的活性物质层的性能，并最终影响电极组件的性能。
基于以上考虑，发明人经过深入研究设计了一种制痕装置，制痕装置包括附接机构、涂布机构及剥离机构。附接机构用于在基材的制痕区附接遮挡件。涂布机构沿基材的输送方向设置于附接机构的下游，涂布机构用于对基材进行涂布。剥离机构沿输送方向设置于涂布机构的下游，剥离机构用于使遮挡件脱离基材，以在制痕区形成刻痕。
该制痕装置通过附接机构在基材上附接遮挡件，遮挡件可对制痕区进行遮挡，以免涂布机构对基材进行涂布时将涂料涂覆至制痕区。涂布机构涂布完成后，剥离机构可使遮挡件脱离基材，以在制痕区形成刻痕。采用该制痕装置，避免了使用激光制痕，避免了在涂层上形成热影响区，使得制痕后的极片制造的电极组件性能较好。
本申请实施例公开的制痕装置适用于在极片上制痕，极片用于叠片制造电极组件，进而可制成电池。需要说明的是，本申请实施例公开的制痕装置同样适用于其他需要涂覆制造的工件的制痕。
请参照图1，配合参照图2，图1为本申请一些实施例提供的制痕装置10的结构示意图。图2为本申请一些实施例提供的料带700的结构示意图。本申请实施例提供了一种制痕装置10，制痕装置10包括附接机构100、涂布机构200及剥离机构300。附接机构100用于在基材600的制痕区附接遮挡件710。涂布机构200沿基材600的输送方向设置于附接机构100的下游，涂布机构200用于对基材600进行涂布。剥离机构300沿输送方向设置于涂布机构200的下游，剥离机构300用于使遮挡件710脱离基材600，以在制痕区形成刻痕。
附接机构100是将遮挡件710附接于制痕区的机构。其中，制痕区是指基材600上需要制出刻痕的区域。“附接”是指遮挡件710遮挡或覆盖于制痕区，这里遮挡件710可以与制痕区有连接关系，例如，遮挡件710粘接于制痕区。遮挡件710也可以与制痕区没有连接关系，例如，遮挡件710只是贴靠于制痕区。
遮挡件710是对制痕区起到遮挡作用的部件，遮挡件710能够遮挡制痕区，以避免涂布机构200在涂布时将涂料涂布至制痕区内。
涂布机构200是用于将涂料涂布至基材600的机构。例如，制痕装置10用于对极片制痕时，涂料为活性物质。涂布机构200将活性物质涂布于基材600，以便于在基材600上形成活性物质层。例如，涂布机构200可以包括涂布头210，涂布头210用于对基材600进行涂布。可选地，制痕装置10包括过辊，涂布头210和过辊分别位于基材600的厚度方向的两侧，基材600具有缠绕于过辊缠绕区域，涂布头210用于向缠绕区域的背离过辊的表面进行涂布。
剥离机构300是将遮挡件710从基材600上剥离的机构。剥离机构300将遮挡件710从基材600上剥离后，由于制痕区由于未涂覆涂料而形成刻痕。
附接机构100、涂布机构200及剥离机构300沿着基材600的输送方向依次设置，以先在基材600上附接遮挡件710，再在基材600上涂布，最后将遮挡件710从基材600上剥离。
该制痕装置10通过附接机构100在基材600上附接遮挡件710，遮挡件710可对制痕区进行 遮挡，以免涂布机构200对基材600进行涂布时将涂料涂覆至制痕区。涂布机构200涂布完成后，剥离机构300可使遮挡件710脱离基材600，以在制痕区形成刻痕。采用该制痕装置10，避免了使用激光制痕，避免了在涂层上形成热影响区，使得制痕后的极片制造的电极组件性能较好。
需要说明的是，刻痕的形状和尺寸可以根据遮挡件710遮挡的制痕区的形状和尺寸来决定。也即更换不同形状和尺寸的遮挡件710能够得到不同形状和尺寸的刻痕。
请参照图1，配合参照图2，在一些实施例中，附接机构100包括放卷机构110、张贴件120及第一收卷机构130。放卷机构110用于放卷料带700。料带700包括带体720和多个遮挡件710，多个遮挡件710间隔设置于带体720。张贴件120用于将料带700张贴于基材600，以使遮挡件710张贴于制痕区。第一收卷机构130用于收卷带体720并分离遮挡件710与带体720。
放卷机构110能够实现对料带700的放卷，例如，放卷机构110包括放卷辊，料带700缠绕于放卷辊，当放卷辊转动时，放卷辊放卷缠绕于其上的料带700。
对于极片来说，其需要制出的刻痕一般沿着极片的宽度方向延伸，多个刻痕沿着极片的长度方向间隔布置。与之相适应地，料带700包括带体720和多个间隔设置于带体720的遮挡件710，带体720一方面能够为遮挡件710提供临时固定，另一方面带体720便于卷绕和放卷。多个间隔设置于带体720的遮挡件710在料带700张贴至基材600时，张贴于多个间隔设置的制痕区。
张贴件120是用于将料带700张贴于基材600的张贴部件。料带700张贴于基材600时，遮挡件710张贴于制痕区，带体720可以张贴于基材600，也可以不张贴于基材600。为了便于第一收卷机构130收卷带体720，在本实施例中，带体720不张贴于基材600。
第一收卷机构130是收卷带体720的机构。例如，第一收卷机构130包括第一收卷辊，带体720缠绕于第一收卷辊，当第一收卷辊转动时，第一收卷辊收卷缠绕于其上的带体720。在第一收卷机构130收卷带体720时，由于遮挡件710张贴于基材600，遮挡件710与带体720之间的连接力较小，可将带体720与遮挡件710分离。带体720由第一收卷机构130回收，遮挡件710保持张贴于基材600。
料带700包括带体720和多个遮挡件710，通过将多个遮挡件710设置于带体720上，以便于通过放卷机构110对料带700进行放卷，在放卷机构110对料带700放卷时，张贴件120可将料带700张贴至基材600。第一收卷机构130能够收卷带体720，让张贴在基材600上的遮挡件710与带体720分离，这样即可实现将遮挡件710自动张贴至制痕区，张贴效率较高，自动化程度较高。
在一些实施例中，张贴件120为张贴辊，张贴辊用于将料带700辊压至基材600。
张贴辊为辊子结构。料带700位于基材600与张贴辊之间，张贴辊能够将料带700辊压至基材600，以将遮挡件710张贴至基材600上。
通过张贴辊将料带700辊压至基材600，即可使遮挡件710张贴在基材600上，带体720没有粘性而易于在第一收卷机构130的作用下与遮挡件710分离。采用张贴辊辊压的方式实现张贴，张贴的稳定性高，能够将遮挡件710平整地张贴至基材600，并且遮挡件710能够被压实于基材600，避免张贴不牢而导致遮挡件710掉落。
在另一些实施例中，张贴件120为张贴板，张贴辊用于将料带700挤压至基材600。
张贴板为板状结构。料带700位于基材600与张贴板之间，张贴板能够将料带700挤压至基材600，以将遮挡件710张贴至基材600上。
通过张贴板将料带700挤压至基材600，即可使遮挡件710张贴在基材600上，带体720没有粘性而易于在第一收卷机构130的作用下与遮挡件710分离。采用张贴板挤压的方式实现张贴，张贴的稳定性高，能够将遮挡件710平整地张贴至基材600，并且遮挡件710能够被压实于基材600，避免张贴不牢而导致遮挡件710掉落。
在一些实施例中，附接机构100包括驱动机构，驱动机构连接于张贴辊，基材600贴靠于张贴辊，以输送基材600。
驱动机构是用于驱动张贴辊转动的机构。例如，驱动机构可以为电机。当然，驱动机构也可以为内燃机。又如，驱动机构可以为直线驱动件和传动机构，传动机构连接于直线驱动件及张贴辊。直线驱动件输出直线运动，传动机构将直线驱动件输出的直线运动转化为转动运动，并带动张贴辊转动。
基材600贴靠于张贴辊既包括基材600缠绕于张贴辊的面接触方式，又包括基材600与张贴辊相切的线接触方式。
通过驱动机构驱动张贴辊转动，使得张贴辊能够主动转动以辊压料带700，提升辊压效果(张贴效果)。将基材600贴靠于张贴辊，这样，在张贴辊将料带700辊压至基材600时，张贴辊也能够同时带动基材600移动，以对基材600进行输送。
在另一些实施例中，附接机构100包括附接机械手，附接机械手用于将遮挡件710附接于基材600的制痕区。
请参照图3，图3为本申请一些实施例提供的制痕装置10(包括两个附接机构100)的结构示意图。在一些实施例中，制痕装置10包括两个附接机构100和两个涂布机构200，两个附接机构100分别位于基材600的厚度方向上的两侧。两个涂布机构200分别位于厚度方向的两侧。
两个附接机构100分别用于对基材600在厚度方向上的两侧附接遮挡件710。而两个涂布机构200则分别用于对基材600在厚度方向上的两侧进行涂布。
在基材600的厚度方向上的每一侧均设置有一个附接机构100和一个涂布机构200，这样，可以在基材600的厚度方向上的两侧分别附接遮挡件710，并通过涂布机构200对基材600的厚度方向上的两侧进行涂布，在剥离机构300剥离遮挡件710后，基材600在厚度方向上的两侧均形成有刻痕。
请参照图3，在一些实施例中，沿厚度方向，两个附接机构100相对布置。
“两个附接机构100相对布置”主要是指两个附接机构100的张贴件120相对设置。两个张贴件120相对设置是指两个张贴件120在基材600的输送方向上的位置相同，并分别位于基材600在厚度方向上的两侧。第一个张贴件120在对基材600的厚度方向的一侧进行张贴时，第二个张贴件120可以作为支撑部件，对基材600起到支撑作用，以提升第一个张贴件120张贴遮挡件710的质量。与此同时，第二个张贴件120对基材600的厚度方向的另一侧进行张贴，第一个张贴件120可以作为支撑部件，对基材600起到支撑作用，以提升第二个张贴件120张贴遮挡件710的质量。也即两个张贴件120可以互为支撑部件，辅助另一个张贴件120张贴遮挡件710。
通过使两个附接机构100相对布置，两个附接机构100在附接遮挡件710时，可以互相作为支撑部件对基材600进行支撑，而不必额外设置支撑部件支撑基材600来辅助附接机构100附接遮挡件710，在保证附接质量的同时，降低了制痕装置10的成本。
请参照图4，图4为本申请另一些实施例提供的制痕装置10(包括两个附接机构100)的结构示意图。在另一些实施例中，沿厚度方向，两个附接机构100错位布置。
“两个附接机构100错位布置”是指两个附接机构100在基材600的输送方向上的不同位置(也可以理解为两个附接机构100在输送方向上存在上下游关系)，且分别位于基材600的厚度方向上的两侧。
通过将两个附接机构100错位布置，便于充分利用空间。
请参照图4，在一些实施例中，制痕装置10还包括支撑件400，支撑件400与附接机构100一一对应。支撑件400与附接机构100沿基材600的厚度方向相对设置于基材600的两侧，支撑件400用于支撑基材600。
支撑件400是对基材600起到支撑作用的部件。在附接机构100将遮挡件710附接于制痕区时，支撑件400支撑基材600，以保证附接机构100对遮挡件710的附接质量。例如，支撑件400为支撑辊，支撑辊与张贴辊相对布置。在张贴辊向基材600张贴遮挡件710时，支撑件400可支撑基材600，以保证张贴辊能够稳定地将遮挡件710张贴至制痕区。又如，支撑件400为支撑台，支 撑台与张贴辊相对布置。
通过设置支撑件400，辅助支撑基材600，以便于附接机构100在支撑件400支撑的基材600上附接遮挡件710，保证遮挡件710稳定可靠地附接在基材600上。
在一些实施例中，遮挡件710上设置有胶层，附接机构100用于在基材600的制痕区粘接遮挡件710。
“遮挡件710上设置有胶层”也可以理解为遮挡件710具有粘性。例如，遮挡件710可以为胶带。胶带既可以是单面胶，也可以是双面胶。
通过在遮挡件710上设置胶层，使得遮挡件710与基材600的连接更牢固，防止在涂布过程中遮挡件710脱离基材600。
请参照图5，图5为本申请一些实施例提供的剥离机构300剥离遮挡件710的示意图。料带700包括连接件730，连接件730连接多个遮挡件710。剥离机构300包括第二收卷机构310，第二收卷机构310用于收卷连接件730，以使遮挡件710脱离基材600。
连接件730是胶带上连接多个遮挡件710的部件。第二收卷机构310是能够收卷连接件730的机构。例如，第二收卷机构310包括第二收卷辊，连接件730缠绕于第二收卷辊，当第二收卷辊转动时，第二收卷辊收卷缠绕于其上的连接件730。
通过设置连接件730连接多个遮挡件710，通过第二收卷机构310收卷连接件730，即可将多个遮挡件710从基材600上剥离，剥离遮挡件710的效率较高，并且成本低廉。
在另一些实施例中，剥离机构300包括剥离机械手，剥离机械手用于遮挡件710从制痕区剥离。
请参照图5，在一些实施例中，张贴件120用于将连接件730张贴于基材600的宽度方向的至少一侧。
连接件730可以为一个，一个连接件730连接多个遮挡件710的一端。当连接件730为一个时，连接件730可以张贴于基材600在宽度方向上的一侧。连接件730也可以为两个，两个连接件730连接多个遮挡件710，且两个连接件730位于遮挡件710的两端。这样，两个连接件730可张贴于基材600宽度方向上的两侧。
通过张贴件120将连接件730张贴于基材600在宽度方向上的至少一侧，连接件730同样起到了遮挡作用，使得涂布机构200在对基材600进行涂布时不会将涂料涂布至连接件730张贴的区域，可以在基材600的宽度方向的至少一侧留出极耳预留区，便于在基材600上形成极耳。另外，将连接件730张贴于基材600在宽度方向上的至少一侧还不会对涂布过程造成影响，有利于保证涂布质量。
请参照图6，图6为本申请一些实施例提供的制痕装置10(包括辊压机构500)的结构示意图。在一些实施例中，制痕装置10包括辊压机构500，辊压机构500沿输送方向设于涂布机构200的下游，辊压机构500用于辊压基材600。
辊压机构500是用于对基材600进行辊压的机构。将辊压机构500设置于涂布机构200的下游，以便于将涂布机构200涂布于基材600的涂料压实。例如，辊压机构500包括两个压辊510，两个压辊510在基材600的厚度方向上相对布置，两个压辊510配合对基材600进行辊压。
通过设置辊压机构500，便于将涂布于基材600的涂料压实，提升极片的性能。
在一些实施例中，辊压机构500设于剥离机构300的上游。通过将辊压机构500设置在剥离机构300的上游，使得辊压机构500将涂料压实后再通过剥离机构300剥离遮挡件710，由于涂料已经被压实，可以避免剥离机构300在剥离遮挡件710时将涂料蹭离基材600。另外，在剥离遮挡件710之前对涂料进行辊压，由于遮挡件710还占据着制痕区的位置，可以防止涂料被辊压至制痕区内。
本申请实施例还提供了一种叠片制造系统，叠片制造系统包括上述的制痕装置10。
根据本申请的一些实施例，请参照图1～图5。
本申请实施例提供了一种制痕装置10，制痕装置10包括附接机构100、涂布机构200及剥离机构300。附接机构100用于在基材600的制痕区附接遮挡件710。涂布机构200沿基材600的输送方向设置于附接机构100的下游，涂布机构200用于对基材600进行涂布。剥离机构300沿输送方向设置于涂布机构200的下游，剥离机构300用于使遮挡件710脱离基材600，以在制痕区形成刻痕。附接机构100包括放卷机构110、张贴件120及第一收卷机构130。放卷机构110用于放卷料带700，料带700包括带体720和多个遮挡件710，多个遮挡件710间隔设置于带体720。张贴件120用于将料带700张贴于基材600，以使遮挡件710张贴于制痕区。第一收卷机构130用于收卷带体720并分离遮挡件710与带体720。料带700包括连接件730，连接件730连接多个遮挡件710；剥离机构300包括第二收卷机构310，第二收卷机构310用于收卷连接件730，以使遮挡件710脱离基材600。制痕装置10包括辊压机构500，辊压机构500沿输送方向设于涂布机构200的下游且设于剥离机构300的上游，辊压机构500用于辊压基材600。
该制痕装置10通过附接机构100在基材600上附接遮挡件710，遮挡件710可对制痕区进行遮挡，以免涂布机构200对基材600进行涂布时将涂料涂覆至制痕区。涂布机构200涂布完成后，剥离机构300可使遮挡件710脱离基材600，以在制痕区形成刻痕。采用该制痕装置10，避免了使用激光制痕，避免了在涂层上形成热影响区，使得制痕后的极片制造的电极组件性能较好。料带700包括带体720和多个遮挡件710，通过将多个遮挡件710设置于带体720上，以便于通过放卷机构110对料带700进行放卷，在放卷机构110对料带700放卷时，张贴件120可将料带700张贴至基材600。第一收卷机构130能够收卷带体720，让张贴在基材600上的遮挡件710与带体720分离，这样即可实现将遮挡件710自动张贴至制痕区，张贴效率较高，自动化程度较高。
通过设置连接件730连接多个遮挡件710，通过第二收卷机构310收卷连接件730，即可将多个遮挡件710从基材600上剥离，剥离遮挡件710的效率较高，并且成本低廉。通过设置辊压机构500，便于将涂布于基材600的涂料压实。通过将辊压机构500设置在剥离机构300的上游，使得辊压机构500将涂料压实后再通过剥离机构300剥离遮挡件710，由于涂料已经被压实，可以避免剥离机构300在剥离遮挡件710时将涂料蹭离基材600。另外，在剥离遮挡件710之前对涂料进行辊压，由于遮挡件710还占据着制痕区的位置，可以防止涂料被辊压至制痕区内。
该制痕装置10利用涂布前在基材600上把制痕区用遮挡件710贴覆，辊压后再把遮挡件710与基材600剥离形成刻痕，优化了工艺制程，提高了制痕效率和优率，同时也消除了制痕热影响区问题，提高了电池的整体安全性。
