具体实施方式
下面详细描述本实用新型的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本实用新型，而不能解释为对本实用新型的限制。
一方面，本实用新型提供了一种层压装置，用于将柔性太阳能电池片M与保护层N压装贴合，如附图1所示，该层压装置包括：传送结构1、加热结构2、层压滚轮结构3。其中，加热结构2设置于传送结构1上，用于对传送结构1上的柔性太阳能电池片M进行加热；层压滚轮结构3设置于传送结构1的输出端，用于在加热后的柔性太阳能电池片M表面层压保护层N。
其中，传送结构1与层压滚轮结构3可连续设置，具体操作时，柔性太阳能电池片M经传送结构1传送至层压滚轮结构3，同时，保护层N也一同传送至层压滚轮结构3，此时，二者通过层压滚轮结构3进行压合，之后即可进入下一个工序。
传送结构1的输出端可以与层压滚轮结构3之间连接，也可以间隙设置，能够保证柔性太阳能电池片M被传送结构1输送至层压滚轮结构3进行滚压即可。
作为一种示例，柔性太阳能电池片M可以为电池条，保护层N为防水且高光透过率的复合材料。
本实用新型提供的层压装置，通过将加热结构2设置在传送结构1上，直接对传送结构1上的柔性太阳能电池片M进行加热，大大加快升温的速度，提高热量利用率，保证柔性太阳能电池片M与保护层N之间的充分粘合，有效降低非必要能耗。而且，通过层压滚轮结构3对加热后的柔性太 阳能电池片M与保护层N进行压合，不需要另外引入粘结剂，节约了成本。
传送结构1可以设置为多种结构，在基于容易传送柔性太阳能电池片M的前提下，给出以下示例：
如附图1所示，传送结构1包括：传送带11和中间支持平台12，传送带11、中间支持平台12、层压滚轮结构3依次设置，加热结构2设置在中间支持平台12上。
柔性太阳能电池片M被传送带11依次传送至中间支持平台12、层压滚轮结构3，当柔性太阳能电池片M经过中间支持平台12的过程中，由中间支持平台12上的加热结构2直接对柔性太阳能电池片M进行接触加热，之间没有传热介质的存在，直接进行热传递，大大加快升温的速度，提高了生产效率，有效降低非必要能耗。
需要说明的是，传送带11、中间支持平台12、层压滚轮结构3之间可以依次连接，也可以不连接，能够实现传动柔性太阳能电池片M即可。
中间支持平台12固定设置于传送带11与层压滚轮结构3之间，并且，传送带11与中间支持平台12的上表面齐平，或者，传送带11的上表面高于中间支持平台12的上表面，中间支持平台12的上表面与层压滚轮结构3的输入端相对，以利于将柔性太阳能电池片M传送至层压滚轮结构3中。传送带11可以由驱动轮进行驱动转动，以使传送带11能够转动传动。
作为一种示例，柔性太阳能电池片M通过真空吸力被吸附于传送带11上，传送带11带动柔性太阳能电池片M传动至中间支持平台12上后，一部分柔性太阳能电池片M还在传送带11上，柔性太阳能电池片M的端部伸入层压滚轮结构3的输入端后，在层压滚轮结构3的带动下，使得柔性太阳能电池片M脱离中间支持平台12。
加热结构2可以通过多种方式设置于传送结构1上，考虑到加热结构2能够直接对通过中间支持平台12上的柔性太阳能电池片M进行加热，中间支持平台12上可以设置有导通上表面的开孔121，加热结构2设置在开孔121中。
控制加热结构2在开孔121中加热，能够对经过中间支持平台12上的柔性太阳能电池片M直接加热，避免造成热量浪费。
考虑到加热结构2不会影响柔性太阳能电池片M在中间支持平台12上通过，作为一种示例，加热结构2包括加热端；加热端的顶面低于中间 支持平台12的上表面，或者，加热端的顶面与中间支持平台12的上表面齐平。
考虑到能够使柔性太阳能电池片M均匀受热，以便于柔性太阳能电池片M与粘合层N之间的牢固粘结，还避免柔性太阳能电池片M由于一次受热而出现内应力，给出以下示例：
开孔121和加热端的数目均为多个，且一一对应设置；多个开孔121沿柔性太阳能电池片M的移动方向间隔设置于中间支持平台121上。
进一步地，为了节省能耗，且避免柔性太阳能电池片M上的某一位置由于仅一次高温加热而出现内应力，影响柔性太阳能电池片M的性能，多个加热端的加热温度沿柔性太阳能电池片M的移动方向逐渐增大。
如此设置，能够使柔性太阳能电池片M上的同一位置可以经过多次加热，避免对柔性太阳能电池片M仅进行一次高温加热而影响其性能。并且，多个加热端的加热温度沿柔性太阳能电池片M的移动方向逐渐增大，还避免了浪费热量。此外，如此设置，还利于柔性太阳能电池片M与粘结层N之间的牢固粘结。
考虑到容易更换加热结构2，加热结构2的加热端可拆卸地设置于开孔121中。
举例来说，加热结构2的加热端可以卡接于开孔121中。加热端的外壁上可以设置卡接件，开孔121的内壁上可以设置卡接槽，通过使卡接件卡接于卡接槽内，实现加热端与开孔121之间的卡接。通过使卡接件脱离卡接槽，使加热端与开孔121之间拆卸。
其中，开孔121可以上下贯穿中间支持平台12，也可以为导通至中间支持平台12的上表面的开口槽。
在本实用新型实施例中，加热结构2可以选为多种，例如，加热结构2可以为热风枪、加热片、或红外线加热管。
上述几种加热结构2的价格低廉，加热效果好，容易获取。
上述提及，层压滚轮结构3用于对柔性太阳能电池片M和保护层N进行层压，层压滚轮结构3的结构可以设置为多种，作为一种示例，如附图1所示，层压滚轮结构3包括：同步转动的上层压滚轮31与下层压滚轮32，上层压滚轮31与下层压滚轮32贴合设置。
当加热后的柔性太阳能电池片M被传送至层压滚轮结构3时，上层压 滚轮31与下层压滚轮32同时开始相对转动，二者相互挤压转动从而提供压力，对加热后的柔性太阳能电池片M与保护层N进行压合，并且，转动力使压合后的柔性太阳能电池片M与保护层N输出，而且，不需要额外引入粘结剂，节约了成本。
考虑到能够对压合后的柔性太阳能电池片M与保护层N临时储存，从而防止后续设备故障造成的层压产品堆积浪费，更适合于与其他设备组成自动化产线，如附图1所示，本实用新型实施例提供的层压装置还包括：缓冲结构4；缓冲结构4设置于层压滚轮结构3的输出端，用于储存压合后的柔性太阳能电池片M与保护层N。
缓冲结构4可以设置为多种结构，在基于容易设置，方便调整缓冲速度的前提下，给出以下示例：
如图1所示，缓冲结构4包括：多组连接设置的滑轮组，每组滑轮组包括：两个定滑轮41和一个动滑轮42，两个定滑轮41依次设置在同一水平线上，动滑轮42位于两个定滑轮41之间，且动滑轮42可相对两个定滑轮41做往复运动，压合后的柔性太阳能电池片M与保护层N依次穿过一个定滑轮41、动滑轮42、另一个定滑轮41。
其中，缓冲结构4对压合后的产品进行缓存，防止后续设备的故障造成正在进行的压合工作中断，造成产品浪费，缓冲结构4的设置，使得本实用新型的滚轮式层压装更适合于与其他设备组成自动化产线，稼动率高。
具体地，缓冲结构4包括多组滑轮组，多组滑轮组依次连续设置，每组滑轮组包括两个定滑轮41和一个动滑轮42，动滑轮42可相对两个定滑轮41做往复运动，例如：沿两个定滑轮41的中线远离或者靠近两个定滑轮41运动，附图1中虚线所示的动滑轮42即为下方实线动滑轮42靠近定滑轮41时的状态，压合后的柔性太阳能电池片M依次穿过，即绕过一个定滑轮41、动滑轮42、另一个定滑轮41，动滑轮42的运动使得本实用新型的灵活性更高，即定滑轮41与动滑轮42远离，则缠绕的柔性太阳能电池片M长度增加，反之则减少，从而实现对柔性太阳能电池片M的灵活存储。
动滑轮42的运动实现方式有多种，举例来说，在动滑轮42运动轨迹处设置限位轨道，使得动滑轮42沿该限位轨道运动，也可以将各组的动滑轮42通过一个连接板连接为整体，通过限制连接板的运动，从而实现对动滑轮42运动的控制。在上述两种情况中，动滑轮42可通过连接轴或者连 接板动力驱动单元连接，通过驱动单元带动连接轴或者连接板上下运动，以带动动滑轮42上下运动。其中，动力驱动单元可以为能够上下运动的电动推拉杆。
另外，定滑轮41也可通过轴与其他部件连接，便于其旋转。
考虑到能够自动化地对保护层N进行输送，如附图1所示，本实用新型实施例提供的层压装置还包括：保护层输送结构5，保护层输送结构5用于将保护层N输送至层压滚轮结构3。
当层压滚轮结构3开始转动时，同时通过保护层N本身带动保护层输送结构5转动，从而将保护层N向前传送至层压滚轮结构3，由层压滚轮结构3对加热后的柔性太阳能电池片M与保护层N进行压合。保护层输送结构5本身也可自发转动，实现对保护层N传送。
保护层输送结构5可以设置为多种结构，在基于结构简单的前提下，给出以下示例：如附图1所示，保护层输送结构5包括：缠绕轮51、导向轮52，缠绕轮51用于缠绕放置保护层N，工作时，保护层N通过导向轮52导向，并从缠绕轮51输送至层压滚轮结构3。
需要说明的是，缠绕轮51和导向轮52可以在保护层N的带动下转动，也可以自转。
当缠绕轮51和导向轮52可以自转时，可以通过驱动结构(例如电机)来驱动缠绕轮51或导向轮52转动。
考虑到能够灵活地控制本实用新型实施例提供的层压装置，如附图2所示，本实用新型实施例提供的层压装置还包括：与传送结构1、加热结构2、层压滚轮结构3均电连接的控制器6。
控制器6能够对传送结构1、加热结构2、层压滚轮结构3能否工作进行控制，使得本实用新型实施例提供的层压装置在实际使用时极为方便且实用。
其中，控制器6控制传送结构1传送柔性太阳能电池片M，控制器6控制加热结构2对柔性太阳能电池片M进行加热，控制器6控制层压滚轮结构3对柔性太阳能电池片M和保护层N进行压合。
作为一种示例，如附图2所示，缓冲结构4与控制器6电连接，以使控制器6可以控制缓冲结构4对压合后的柔性太阳能电池片M和保护层N的缓冲速度。
作为一种示例，针对于保护层输送结构5通过驱动来进行传动的情形，如附图2所示，保护层输送结构5可以与控制器6电连接，以利于控制器6直接对保护层输送结构5的工作状态进行控制。
考虑到不仅可以降低能耗，且可以保证柔性太阳能电池片M与保护层N之间的压合温度，如附图1所示，本实用新型实施例提供的层压装置还包括：用于监测加热结构2的加热温度的温度检测结构7。
通过监测加热结构2的加热温度，以利于更好地控制其加热温度，进而可以保证柔性太阳能电池片M与保护层N之间的压合温度。
具体地，温度检测结构7可以设置于靠近加热结构2处或靠近层压滚轮结构3处。
通过将温度检测结构7设置于靠近加热结构2处，能够直接检测其加热温度，通过将温度检测结构7设置于靠近层压滚轮结构3处，不仅间接检测了加热结构2的加热温度，并且，可以直接检测柔性太阳能电池片M与保护层N之间的压合温度。如此，利于降低能耗，还利于柔性太阳能电池片M与保护层N之间的压装贴合。
进一步地，如附图2所示，温度检测结构7可以与控制器6电连接。
如此设置，控制器6能够根据温度检测结构7所监测的温度，自动地控制加热结构2的加热温度，进而使压合保持最佳温度，避免温度过高造成热量浪费，以及避免温度过低而不能使柔性太阳能电池片M与保护层N充分粘合。
作为一种示例，温度检测结构7为温度探头。在本实用新型实施例中，可采用温度探头，也可是其他温度传感器，通过温度探头检测压合时的温度，监测压合温度，并将温度信息反馈给控制器6，由控制器6对加热结构2进行控制，从而实现温度的闭环控制。
考虑到加热结构2和层压滚轮结构3不会在没有柔性太阳能电池片M的条件下工作，以节能降耗。作为一种示例，如附图1所示，本实用新型实施例提供的层压装置还包括：位置检测结构8，位置检测结构8设置在传送带11与中间支持平台12之间，位置检测结构8用于检测柔性太阳能电池片M的位置。
通过位置检测结构8来获取传送带11的位置信息，进而利于控制加热结构2和层压滚轮结构3的工作状态，以节能降耗。
作为一种示例，如附图2所示，位置检测结构8与控制器6电连接。
如此设置，利于控制器6根据位置检测结构8所检测的柔性太阳能电池片M的位置信息，直接控制加热结构2和层压滚轮结构3的工作状态。
举例来说，当位置检测结构8检测到柔性太阳能电池片M经过时，即由传送带11传送至中间支持平台12上时，控制器6根据位置检测结构8所检测的位置信息，可以控制加热结构2和层压滚轮结构3顺次工作，以对柔性太阳能电池片M进行加热和层压。当位置检测结构8未检测到柔性太阳能电池片M经过时，控制器6根据位置检测结构8所检测的位置信息，控制加热结构2和层压滚轮结构3不工作，以节省能耗。
其中，位置检测结构8可以为位置传感器。位置传感器可以通过发送脉冲方式来检测是否有柔性太阳能电池片M经过。当位置传感器检测到柔性太阳能电池片M正在经过时，将检测信号反馈至控制器6，由控制器6即启动加热结构2对柔性太阳能电池片M进行加热。
作为一种示例，本实用新型实施例提供的层压装置在工作时，第一，根据位置检测结构8的信号，将沉积后的柔性太阳能柔性太阳能电池片M依次放在传送结构1上，传送结构1将柔性太阳能电池片M传输至层压滚轮结构3。第二，柔性太阳能电池片M在经过中间支持平台12的过程中，通过加热结构2完成加热，并通过温度检测结构7，监测压合温度，实现闭环控制。第三，保护层N可以是绕成卷的复合材料，通过上层压滚轮31与下层压滚轮32压合，当加热后的柔性太阳能电池片M达到层压滚轮结构3时，层压滚轮结构3开始转动，同时带动保护层N与柔性太阳能电池片M向前送料，完成压合功能。第四，压合后的产品，先经过一个缓冲结构4，实现缓存，防止后续设备的故障而造成正在压合的工作中断。
综上，本实用新型实施例提供层压装置的结构简单，易于维护，设备稼动率高。
另一方面，本实用新型实施例提供了上述提及的任一种层压装置的使用方法，该使用方法包括：
通过传送结构1传送柔性太阳能电池片M，并且通过设置于传送结构1上的加热结构2对柔性太阳能电池片M进行加热；
通过层压滚轮结构3对由传送结构1传送的柔性太阳能电池片M、以 及保护层M进行压合。
上述使用方法简单，通过直接对传送结构1上的柔性太阳能电池片M进行加热，大大加快升温的速度，提高热量利用率，保证柔性太阳能电池片M与保护层N之间的充分粘合，有效降低非必要能耗。而且，通过层压滚轮结构3对加热后的柔性太阳能电池片M与保护层N进行压合，不需要另外引入粘结剂，节约了成本。
考虑到能够高效、自动、可控地使用，本实用新型实施例提供的层压装置的使用方法还包括：
