请参阅图1和图3。图1是根据本公开一些实施方式的加热设备的整体结构示意图。图3是根据本公开一些实施方式载片台上表面的结构示意图。
如图1所示，根据本公开一些实施例提供的一种用于片状电池的加热设备，包括：载片台10、上盖20和加热装置30。所述上盖20与所述载片 台10活动连接，以使得所述上盖20能够在覆盖在所述载片台10上表面的第一状态以及与所述载片台10的上表面分离的第二状态之间转换。所述载片台10设置有贯穿所述载片台10的通道101。所述加热装置30固定设置在所述载片台10的下方，并配置为通过所述通道101输送热量从而对置于所述载片台10上的片状电池进行加热。
在一些实施例中，所述片状电池例如可以为半成品光伏电池。
在一些实施例中，所述片状电池例如可以为柔性薄膜光伏电池芯片。
在一些实施例中，所述载片台10设置有从其上表面连通至底部的通道101；所述加热装置30固定设置在所述载片台10的底部并与所述通道101连通；所述加热装置30通过所述通道101向所述载片台10输送热量从而对置于所述载片台10上的片状电池进行加热。
所述片状电池是指形状为片状的电池，既可以为条形片状，也可以为带形片状，具体可以为片状锂电池、半成品电池或光伏柔性芯片电池等，但不限于上述列举。在以下的实施例中，以对半成品电池的处理为例子进行说明。在下述实施例的描述中，对半成品电池的说明并非是对片状电池技术方案以及技术方案实施的限定，只是为了让本领域技术人员以及公众更好、更清晰的了解本公开技术方案而进行的示例性说明。
所述上盖20与所述载片台10活动连接。所述加热设备处于工作状态时，所述上盖20覆盖在所述载片台10上表面，形成容纳半成品光伏电池的空间，避免所述加热设备中的热量散发到周围环境中。
在一些实施例中，本公开实施例的加热设备在柔性电池芯片生产线中使用。当半成品电池被传送至所述加热设备的载片台10上时，所述加热装置30通过所述通道101输送热量从而对置于所述载片台10上的半成品光伏电池进行加热。载片台10的长度方向沿生产线的传输方向，载片台10宽度方向的两端分别与传送带连接。传送带将半成品电池芯片从载片台10宽度的一端送上载片台10，并在传送带的推动下，向载片台10宽度的另一端输送。然后，半成品电池芯片从载片台10再一次输送至传送带上。传送带将半成品电池芯片输送至下一层压工序，从而实现连续喂料以及连续自动作业、也实现了与层压装置的配合工作。在半成品电池芯片的尺寸较 大时，只要在载片台10的上游和下游设置传送装置(例如传送带)即可实现加热设备的连续喂料以及连续自动作业。本领域技术人员容易理解，在另一些实施例中，载片台10还可以设置传送装置，以实现加热设备的连续喂料以及连续自动作业。
本公开的加热设备也可以通过人工配合离线作业，实现对半成品电池的加热，并送至下一工序；或作为样品的加热设备进行使用。其中，离线作业是指离开生产线作业。通常情况下在线上使用或离线使用时，上盖20与载片台10处于闭合状态。
在本公开的一些实施例中，上盖20采用金属材质，载片台10整体也采用金属材质。金属材质可以为银、铜、铝、铁等金属或者这些金属的合金或化合物。例如上盖20为不锈钢。但不锈钢20以及载片台10的材质并不限于上述列举。只要能使本公开的加热设备具有良好的导热性和耐热性的材质，均可应用于制作本公开的加热设备。
另外，载片台10可以设置为实心结构、也可以设置为空心结构，载片台10的形状长方形、正方形、圆形、椭圆形等任意形状，优选为长方形。在一些实施例中，载片台10的形状为长方形，且在长方形的宽度两端设置有从上表面向下延伸形成的弧面或曲面，以便于传送带上的半成品电池滑动至载片台10上。载片台10的形状不限于上述列举。上盖20形状可以为长方形、正方形、圆形、椭圆形等任意形状，优选为与载片台10形状相匹配。
如图3和图8所示的，载片台10上的通道101可以有多个，例如为2个、3个、4个或更多个，但不限于上述列举。
在一些实施例中，载片台10形成有多个通道101，对每个通道101分别连接一加热装置30。
图7所示的，在一些实施例中，通道101在载片台10上沿与半成品光伏组件的传输方向垂直的方向延伸。
更进一步地，加热装置为热风枪，且热风枪沿通道101的延伸方向摆动，即热风枪沿图中的上下方向(如图7中的双箭头所示方向)来回摆动，这样在半成品光伏组件从载片台10上通过时，热风枪可以对半成品光伏组 件的尽量多的区域加热，从而使半成品光伏组件受热均匀。
在一些实施例中，在实心结构的载片台10，沿载片台10的内部向上表面延伸出2个、3个或更多个通道101，从而实现多个贯通的通道101与一个加热装置30连接。在载片台10上表面有多个散热的通道101，对半成品电池进行加热。或者采用空心的载片台10，在上表面设置有多个开口，当加热装置30通过通道101对载片台10加热。上述方案可以从多个开口处散热，对半成品电池进行加热。载片台10的通道101设置不限于上述列举。
请参阅图5和图6，图3是根据本公开实施方式上盖覆盖在载片台状态的左视图；图4是根据本公开实施方式上盖覆盖在载片台状态的右视图。
在一些可选实施例中，如图3-4所示，在所述上盖20覆盖在所述载片台10的状态下，所述上盖20的下表面与所述载片台10的上表面之间具有缝隙100；所述缝隙100的形状、尺寸与所述半成品光伏电池的形状、尺寸相适配，以使得所述半成品光伏电池能够容纳在所述缝隙100内。
在一些实施例中，所述载片台10的长度方向与光伏电池的传送方向平行。在所述上盖20覆盖在所述载片台10的状态下，所述上盖20与所述载片台10之间的缝隙100沿载片台10的长度方向从一端延伸至另一端。
当上盖20与载片台10闭合时(也就是说上盖20覆盖在载片台10时)，二者之间形成缝隙100。该缝隙100沿载片台10长度方向从一端延伸至另一端，传送带传送的半成品电池可以从一端进入缝隙100，并从另一端出去上述缝隙100可以容纳半成品电池并且半成品电池能从改缝隙100中通过。本公开实施例的加热设备使用时，上盖20覆盖在载片台10可以对加热装置30输送热量的进行保存，载片台10和上盖20具有一定温度，当半成品电池经过缝隙100时，电池先被具有一定温度的载片台10和上盖20进行初步加热，在电池经过通道101上时，再通过加热装置30进行进一步加热，从而使半成品电池受热均匀且受热速度快。
在一些可选实施例中，所述上盖20的下表面具有凹槽，所述凹槽沿所述上盖20的长度方向从一端延伸至另一端；和/或所述载片台10的上表面凹槽，所述凹槽沿上盖20的长度方向从一端延伸至另一端。
以所述载片台10为长方形为例进行说明，上盖20的下表面可以设置为凹槽状，截面近似“U”形，且开口向下。在一些可选实施例中，在上盖20下表面，上盖20的沿长度方向的边缘处设有凸条。在一些可选实施例中，或者在上盖20的下表面的四个角处设置有4个凸台。在一些可选实施例中，上盖20的下表面的与光伏电池的传送方向平行的边缘设置有。在上盖20覆盖在载片台10上表面时，凸条段起到支撑作用，且凸条段可与载片台10形成缝隙100。
载片台10上表面也可设置为凹槽状，关于载片台10上表面设置为凹槽的阐述类似于对上盖20下表面的阐述，这里不再赘述。
在一些可选实施例中，在所述上盖20覆盖在所述载片台10的状态下，所述上盖20的与所述半成品光伏电池的传送方向平行的边缘与所述载片台10贴合，所述上盖20的与所述半成品光伏电池的传送方向垂直的边缘与所述载片台10之间具有间隙。该间隙供所述半成品光伏电池进出。
上盖20以及载片台10的具体形状结构可以不做限定，只要上盖20覆盖于载片台10上，上盖20与载片台10之间存在用于容纳光伏电池的狭缝即可。
图2是根据本公开一些实施方式的上盖及安装在上盖下表面的滚动装置的结构示意图。
在一些可选实施例中，如图2所示，所述的加热设备，还包括固定安装于所述上盖20的下表面的滚动装置40；所述滚动装置40包括至少一个滚动组件；每个所述滚动组件包括滚动体和固定件；所述固定件固定在所述上盖20的下表面；所述滚动体能够相对于所述固定件进行滚动。
所述固定件采用安装座，所述滚动体采用滚珠；所述滚珠嵌设在所述安装座内，并在所述安装座内进行滚动。
所述固定件采用轴，所述滚动体采用滚轮；所述滚轮套设在所述轴上，并绕所述轴进行滚动。
所述固定件采用固定轴，所述滚动体采用滚柱；所述滚柱套设在所述固定轴上，并绕所述固定轴进行滚动。
在一些实施例中，半成品电池置于加热设备时，电池与载片台10接触 的下表面一般为衬底，上表面一般分布有功能膜层，电池的上表面如果与上盖20下表面摩擦，容易损坏功能膜层。所述功能膜层例如可能是光吸收层或者电子传输层，或者是窗口层。
缝隙100在加热装置30的热气的作用下，可能会离开载片台10上表面，贴合在上盖20下表面的滚动装置40表面。上盖20的下表面设置滚动装置40，可以将原本半成品电池在与载片台10的上表面的滑动摩擦转变为滚动摩擦，解决半成品电池上表面薄膜与顶盖20摩擦可能损坏的问题。
在一些实施例中，加热装置30为热风枪；且上盖20下表面设置有滚动装置40。热风枪通过通道加热半成品光伏电池，并且热风枪产生的热风可以托起半成品光伏电池，减少半成品光伏电池与载片台10的摩擦。滚动装置40的设计，还可以减少上盖20与半成品光伏电池上表面间的摩擦，进而保护了电极的完整性以及成品电池的导电效果。
在一些可选实施例中，提供有多个所述滚柱，多个所述滚柱沿所述半成品光伏电池的传送方向依次排列在所述上盖20的下表面。
每个所述滚柱依次固定安装在所述上盖20的下表面，当在外力作用时，每个所述滚柱沿所述半成品光伏电池的传送方向滚动，形成可传送半成品光伏电池的滚道。
当传送带传送半成品电池运送到载片台10上时，由于半成品电池长度较长，通过传送带的摩擦力带动半成品电池的一部分进入缝隙100，且加热装置30的热风将进入缝隙100的半成品电池部分吹至与滚柱贴合，滚柱在半成品电池的带动下，沿传送带传送方向运动，直至将加热好的半成品电池完全移出缝隙100。在一些可选实施例中，如图2所示，每个所述滚轮依次固定安装在所述上盖20的下表面，当在外力作用时，每个所述滚轮沿所述载片台10的长度方向的滚动方向形成滚道。所述载片台10的长度方向沿所述半成品光伏电池的传送方向。
另外，本公开上述实施例中所述的滚动体包括滚柱、滚轮或滚珠等，但不限于上述列举。滚动体可采用耐高温陶瓷材料，例如为氧化铝陶瓷、氮化硅陶瓷、六方氮化硼陶瓷或碳化硅陶瓷，但不限于上述列举的材料。
在一些可选实施例中，所述的加热设备包括挡板50和驱动装置。挡板 50配置为在遮挡所述通道101以使所述通道101关闭的状态和自所述通道101移开以使所述通道101打开的状态之间转换。挡板50能在使所述通道101关闭或打开的状态之间转换。所述驱动装置驱动所述挡板50，以使所述通道101关闭或打开。
在一些可选实施例中，所述挡板50能够在与其连接的驱动装置的驱动作用下移动至所述通道101内、或所述通道101的入口或出口，以打开或关闭所述通道101。
挡板50采用耐高温金属材料制成。由于在生产过程中，加热装置30处于持续加热状态，当载片台10上无半成品电池经过时，通过将挡板50移动至通道101的入口或出口处，以阻挡加热装置30的热风向加热设备的缝隙100输入。挡板50的设计，可以在载片台10上无半成品光伏电池时避免加热装置30直接加热上盖20，以保护设备延长其寿命。挡板50采用耐高温金属材料制成。另外，挡板50的设计还可以使得上盖20的耐高温要求降低，从而降低上盖20以及整个设备的选材难度，降低整个设备成本。整个设备中只有通道101以及加热装置30的相关部分需要时耐高温材料制成。挡板50的设计还可以促使加热装置30对载片台10进行预热，使载片台10具有一定温度，当半成品电池到达载片台10时，先对半成品电池进行一定程度的加热，以提高加热效率和较热效果。此外挡板50可以设计为三角形、菱形、长方形、正方形等任意形状，不限于上述列举，只要挡块的大小和形状能够将通道101封闭即可。
图4是根据本公开实施方式载片台下表面结构示意图。
在一些可选实施例中，如图4所示，所述的加热设备，还包括：挡板容纳腔60，例如可以由所述载片台10形成，设置在所述载片台10的底部，且位于所述通道101口处；所述挡板50能够在挡板容纳腔60内活动；挡板连接杆70，一端与所述挡板50连接，另一端与所述驱动装置连接，以在所述驱动装置的驱动作用下推动所述挡板50移动；连接杆收纳槽80，设置在所述载片台10的底部，且与所述挡板容纳腔60连通，用于容纳并固定所述挡板连接杆70。
在本实施例中，还包括一种情况，当载片台10为空心结构时，所述挡 板容纳腔60可以为设置在空心结构内的几个滑道围成，且形状与挡板50的形状一致或者只要能使挡板50可以在挡板容纳腔60中移动，以打开或关闭通道101即可。
在一些实施例中，所述加热设备还设置有传感器，所述传感器用于检测载片台10上是否存在半成品光伏电池，所述传感器与控制器相连。所述控制器用于在检测到载片台10上存在半成品光伏电池时，控制驱动装置移动挡板50，以使通道101打开。加热装置30可以通过通道101对半成品光伏电池加热。
例如，在生产线上使用本加热设备时，可以在传送带或载片台10或上盖20上设置有传感器，当传感器检测到有半成品电池到达或将到达载片台10时，挡板的驱动装置驱动挡板连接杆70移动，挡板连接杆70带动挡板50滑动，将通道101露出来，使加热装置30吹的热气吹到半成品电池上，进行加热。而后当设备检测到加热后的半成品电池离开载片台10之后，驱动装置驱动挡板连接杆70移动，挡板连接杆70带动挡板50滑动，将通道101口挡住以隔绝加热装置30的热风，从而保护加热设备，延长其使用寿命。
图1是根据本公开实施方式的加热设备整体结构示意图。
在一些可选实施例中，所述的加热设备，如图1所示，还包括连接件90，所述上盖20与所述载片台10通过所述连接件90活动连接；所述连接件90包括第一连接部901和第二连接部902；所述第一连接部901的一端与所述上盖20连接，另一端与所述第二连接部902铰接；所述第二连接部902的一端与所述载片台10连接，另一端与所述第一连接部901铰接。
在本实施例中，第一连接部901和第二链接部902可以设置为近似“U”形的结构。第一连接部901和第二链接部902的一端分别与载片台10或上盖20连接，第一连接部901和第二链接部902的另一端相互铰接连接。上盖20与载片台10可以实现闭合或打开的运动。
在一些可选实施例中，所述的加热设备所述加热装置30包括加热通道301；所述加热通道301的一端与所述载片台10底部固定连接并与所述通道101连通，另一端与外部热源连接。
在一些实施例中，加热装置30采用热风枪，热风枪的出风口与加热通道301连通，加热通道301与载片台10上的通道101连接。已完成对半成品电池的加热。另外本公开上述实施例提到的固定连接的方式可以为焊接、铆接、卡接、螺纹连接或销连接等连接方式，优选为螺纹连接，一方面可以方便加热设备的拆卸与安装，另一方面使设备结构的稳固性更高，但不限于上述列举的固定连接方式。
在本公开的一些实施例，所述半成品光伏电池为未安装顶电极的半成品光伏电池。
在本公开的一些实施例，所述半成品光伏电池为光伏柔性芯片的半成品电池。
本公开的一些实施例中提供一种用于半成品光伏电池的加热设备，用于安装电极之前对半成品光伏电池进行加热。在使用本公开加热设备加热时，半成品光伏电池位于在载片台10与上盖20间之间，加热过程中保持上盖20覆盖在载片台10上，也就是使上盖20与载片台10处于闭合状态，同时，加热装置30产生的热气从载片台10上的通道101吹入上盖20与载片台10处于闭合状态形成的空间内，从而对半成品光伏电池进行高效的加热。
由于半成品光伏电池被送至载片台10之前，加热装置30一直对载片台10本身加热，而载片台10与上盖20均可采用导热性好的金属材料制成，因此，当半成品光伏电池被送至载片台10时，先通过载片台10和上盖20本身具有的温度对半成品光伏电池进行一定程度的加热，同时利用通道101输送的热气进一步加热，从而提高了本公开加热装置30对半成品光伏电池的加热效率。
当半成品光伏电池在该设备内被加热至预设定温度后，立刻输出进行下一道工序，即安装顶电极。由于采用本公开的加热设备对半成品光伏电池进行加热，可以提高其加热效果，且对其通体材料基本无损伤，从而使得在顶电极安装后得到的成品电池不仅具有完整性的电极，该成品电池在实际应用过程中具有良好的导电效果，避免了不通电的现象的发生。另外 本公开加热设备结构简单，安装、拆卸方式灵活，方便维修。
所述加热设备，载片台10和上盖20闭合后能形成缝隙通道，可以使半成品光伏电池通过，该缝隙可对加热装置30的热量进行汇聚，当半成品光伏电池在缝隙通道内时，可以一边经载片台10以及上盖20被预热保存的温度进行加热，一边通过连通在通道101的加热装置30进一步加热，使半成品光伏电池受热均匀且受热速度快。
所述加热设备在上盖20的下表面设置有滚动装置40，减少了上盖20与光半成品光伏电池上表面间的摩擦，间接达到了保护电极的完整性以及成品电池的导电效果。本公开的滚动装置40可在外力的作用下形成与传送带传送方向一致的滚道，有效的控制了对半成品光伏电池的加热时间，进一步有效的控制了生产线中对半成品光伏电池的输送时间。
所述加热设备，在载片台10通道101处设置有挡板50，在半成品光伏电池经过载片台10时，滑动挡板50使加热装置30的热量能够通过通道101输送至载片台10与上盖20之间；当半成品光伏电池离开载片台10时，滑动挡板50至通道101处，隔绝加热装置30的热量，使得加热装置30只对载片台10本身进行预热，使载片台10保持一定的温度。
本公开的一些实施例还提供一种光伏电池的制造方法，包括：
在金属衬底上进行光伏电池的各镀膜制程，形成光伏电池半成品；光伏电池半成品包括除顶电极之外的光伏电池结构，金属衬底为光伏电池的底电极；
对光伏电池半成品进行切割，形成多个单体光伏电池半成品；
形成制造待安装至半成品光伏电池上的顶电极；
通过本公开实施例提供的加热装置，对单体光伏电池半成品进行加热送出；
通过层压装置将顶电极压合在单体光伏电池半成品上，形成单体光伏电池。
后续可以将多个单体光伏电池相互连接，并进行封装形成电池组件。
例如，采用金属箔片作为衬底沉积薄膜，其中的作为衬底的金属箔片 相当于一个电极(底电极)。在生产线上，按照预定规格对带有一个电极的半成品电池进行切割等工艺。通过本公开的加热装置对半成品电池进行加热送出，送出后立刻通过层压的方式压一层顶电极，以将电流引出。后续可以将多个光伏电池相互连接，并进行封装形成电池组件。
本公开的一些实施例还提供一种光伏电池的电极制造方法，包括：
形成制造待安装至半成品光伏电池上的电极；
将所述半成品光伏电池加热至目标温度，例如，可通过本公开上述实施例提供的加热装置对半成品光伏电池进行加热；
将所述电极安装至所述半成品光伏电池。
如图9所示，本公开的一些实施例还提供一种光伏电池的电极制造方法，包括：
电极形成设备301，用于制造待安装至半成品光伏电池上的电极；
根据上述实施例的所述加热设备302，所述加热设备用于将所述半成品光伏电池加热至目标温度；
层压设备303，设置于所述加热设备和所述电极形成设备的下游，用于通过层压将所述电极安装至所述半成品光伏电池。
电极形成设备301用于形成待安装至半成品光伏电池上的电极，具体结构不做限定。在一些实施例中，半成品光伏电池具有底电极，电极形成设备301用于形成顶电极。顶电极例如可以透明电极膜或者镂空的金属膜层。电极形成设备301例如可以是喷射成膜设备或者喷涂成膜设备。半成品光伏电池加热设备可参阅本公开上述实施例，在此不再详述。层压设备303将电极形成设备301形成的电极压合在具有一定温度的半成品光伏电池，使光伏电池结构完整。由于半成品光伏电池压合前经过加热设备302预热，压合时粘附材料融化，从而将电极压合半成品光伏电池上。粘附材料可形成或铺设在半成品光伏电池上，也可形成在待压合的电极上。
应当理解的是，本公开的上述具体实施方式仅仅用于示例性说明或解释本公开的原理，而不构成对本公开的限制。因此，在不偏离本公开的精 神和范围的情况下所做的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。此外，本公开所附权利要求旨在涵盖落入所附权利要求范围和边界、或者这种范围和边界的等同形式内的全部变化和修改例。
