具体实施方式
下面描述本公开的实施例，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。
本实施例提供了一种太阳能电池浆料的干燥方法，适用于本实施例提供的太阳能电池浆料的干燥系统。图1为本实施例提供的太阳能电池浆料的干燥系统的工作原理图，图2为本实施例提供的太阳能电池浆料的干燥系统的结构简图。参照图1和图2，该系统包括激光器1和主控制器2；激光器1设置为对当前电池片3进行干燥；主控制器2设置为根据电池片3的位置信 息，启动激光器1发出激光束12，以对电池片3进行干燥。
可选地，该系统还包括传送带5和传感器6，传送带5设置为将当前电池片3输送至激光器1的下方，还设置为将电池片3输出；传感器6设置为探测电池片3的位置信息；主控制器2还设置为当电池片3输出时，停止激光器1发出激光束12。
电池片3在传送带5上放置时，相邻的两个电池片之间具有间隙4，设置该间隙4最小应能够使得激光器1完成前片电池片干燥后，对下一次电池片进行干燥之前缓解激光器1的启动时间。
可选地，该系统还包括烘干炉体，激光器设置在烘干炉体内。
在本实施例中，经过丝网印刷后的电池片3由丝网印刷工位传送到烘干炉体，由传送带5将电池片3向前传送，当电池片3运行至激光器1下方时，传感器6探测到电池片3，激光器1的输出头11开始输出激光束12。激光器1可以是一台，也可以是两台或多台，激光器1的输出头11输出宽度约为160mm的激光束12，扫描电池片3，从而对电池片3进行干燥。电池片3匀速地通过该均匀的线聚，从而达到被烘干的效果，且线型激光具有光强分布均匀、激光功率可控和加工速度快的特点。当传感器未探测到电池片3时该电池片3干燥结束，激光器1停止进入待机状态，等待下一电池片，重复以上动作直至加工完成。
本实施例提供的太阳能电池浆料的干燥系统通过控制激光器1发出激光束12来对电池片3进行干燥，线型激光器1烘干的炉体可以做的很小，与相关技术相比，节省了占地面积，增加了厂房的利用率。另外，由于激光束12集中在一区域进行烘干加工工艺，并且设置较小的烘干炉体，减小了有机物等其他有害的气体的扩散，所以烘干出的有机物或有害气体可以更好更有效地被集中排出，使烘干效果更佳、减少二次污染，电池片的转换效率也可显著提升；烘干过程中，浆料直接吸收激光辐射并且将周围环境的热损耗降至最低，提升机器的电热利用率，可以使电力能耗减半(相比传统烘干炉、烧 结炉)。
可选地，该系统还包括排风系统7，设置为对干燥电池片3的过程中产生的物质进行排放；主控制器2还设置为在停止激光器1发出激光束12时，停止排风系统7的排风操作；以及在下一个电池片输送到位时，开启排风系统7；或，主控制器2还设置为控制排风系统7持续开启。也就是说，排风系统7可以被单独控制，排风系统7可以是一直处于开启状态，也可以是激光器1开启工作时打开排风系统7。
图3为本实施例提供的太阳能电池浆料的干燥方法的流程图，如图3所示，本实施例还提供了一种太阳能电池浆料的干燥方法，包括如下步骤。
在步骤10中，将当前电池片3输送至激光器1的下方。可选地，可以利用传送带5对电池片3进行输送。
在步骤20中，探测所述电池片3的位置信息。该步骤中，可以利用传感器6探测电池片3的位置信息。
在步骤30中，根据所述位置信息，启动所述激光器1发出激光束12，以对所述电池片3进行干燥。
在对电池片3进行干燥的过程中，可以利用排风系统7对干燥电池片的过程中产生的物质进行排放。排风系统7可以将干燥过程中产生的有机物、挥发物排出至排风管道。
可选地，该步骤30之后，该方法还可以包括以下步骤。
在步骤40中，将所述电池片3输出，并停止所述激光器1发出激光束12。当传感器6没有探测到电池片时，主控制器2发出控制信号，以停止激光器1发出激光束12。
在步骤50中，等待下一个电池片的输送。
重复上述步骤10至步骤50。
可选地，排风系统7可以是一直开启，也可以是跟随激光器1的启动而开启。
当设置排风系统7为一直开启的模式时，步骤30可以为：控制排风系统7持续开启，利用排风系统7对干燥电池片3的过程中产生的物质进行排放。
当设置排风系统7为跟随激光器1的启动而开启的模式时，步骤40还包括：在停止所述激光器1发出激光束12时，停止所述排风系统7的排风操作；步骤50还包括：在下一个电池片输送到位时，开启所述排风系统7。
工业实用性
本公开提供的太阳能电池浆料的干燥方法及系统通过控制激光器发出激光束来对电池片进行干燥，线型激光器烘干的炉体可以做的很小，与相关技术相比，节省了占地面积，增加了厂房的利用率。
