Description
技术领域
本发明涉及一种遮蔽电池片阵列焊带的方法及其设备，属于光伏技术领域。
背景技术
现有太阳能组件系由许多太阳能电池片经串并联，以镀锡的铜带(称互连条),以上下跳接的方式，来将电池片的正负极串连起来形成电池串，之后再将电池串之间以另一镀锡的铜带(称汇流条)串联或并联起来，形成最终回路形成电池片阵列。但由于镀锡铜薄是具备反光的亮银色，与电池片本身颜色(蓝色或黑色)或封装材料(如背板\EVA等)颜色并不一致，而使得在光伏组件无法获得较佳的外视，甚至在某些应用领域，如车载光伏件，或在靠近机场、公路附近安装的光伏组件，都被要求限制光件的反光率。
因此就需要对焊带进行遮蔽，传统的组件遮蔽焊带的方法，如图1所示，是在电池片先用互连条及汇流条完成电池片阵列回路后，先以胶带粘贴在互连条上；之后再用绝缘条放置于汇流条上，以起到遮蔽焊带的效果。
传统方式的缺点在于，由于互连条宽度约在1mm左右，胶带的宽度不能超出太多，以免遮蔽电池片的发电区，而影响组件发电效率。因此在粘贴胶带时需非常小心，不但作业速度慢，而且有一定的比例造成下方焊带露出的情况。再者，使用绝缘条来遮蔽汇流条焊带时，由于其与胶带的材质不同，在封装后会形成颜色上的差异，而影响组件的美观度。
发明内容
本发明的目的在于提供一种提高生产效率的遮蔽电池片阵列焊带的方法及其设备。
为了达到上述目的，本发明的技术方案是：一种遮蔽电池片阵列焊带的方法，包括以下步骤：
第一步：首先将若干个电池片用互连条跳接及汇流条完成电池片阵列回路；
第二步：再采用喷涂设备依照互连条和汇流条的位置，在互连条及汇流条的表面喷涂UV油墨层；
第三步：然后以UV固化的方式使其UV油墨层固化。
优选的，所述UV油墨层的颜色与电池片的颜色接近或相同。
优选的，所述UV固化方式用UV灯照射，使UV油墨发生化学反应形成固化。
采用上述方法，相比于现有的遮蔽焊带方法，不仅提高工作效率，而且可以对互连条和汇流条进行同时遮蔽，使得两者颜色一致，喷涂位置也可调，避免焊带裸露，影响美观。
一种遮蔽电池片阵列焊带的设备，所述电池片阵列的上方设有喷涂设备，喷涂设备包括可以移动的安装平台、喷头、管路和UV灯，所述喷头和UV灯固定连接在安装平台上，且管路连接喷头。
优选的，所述UV灯的瓦数为在30w-200w之间，可装设多套灯组，设在喷头的前后两侧。
采用上述结构后，本发明的安装平台移动路径即为互连条和汇流条的路径，在安装平台移动过程中，管路中持续输送油墨，喷头将油墨喷到互连条和汇流条的上表面，形成UV油墨层。并且在持续喷涂过程中。UV灯对UV油墨层进行固化处理，形成油墨薄膜。一次性喷涂和固化完成，相较于现有的遮蔽焊带提高了生产效率。
附图说明
图1是背景技术遮蔽焊带的结构；
图2是本发明遮蔽焊带的设备结构示意图；
图3是本发明中遮蔽焊带方法示意图。
具体实施方式
以下结合附图给出的实施例对本发明作进一步详细的说明。
如图1所示，现有的遮蔽焊带方法是在电池片2先用互连条1和汇流条4完成电池片阵列回路后，先以胶带5粘贴在互连条1上；之后再用绝缘条6放置于汇流条4上，以起到遮蔽焊带的效果，费时费力。
本发明的一种遮蔽电池片阵列焊带的方法，包括以下步骤：参见图3中a所示，首先将若干个电池片2用互连条1跳接及汇流条4完成电池片阵列回路；参见图3中b所示，再采用喷涂设备20依照互连条1和汇流条4的位置，在互连条1及汇流条4的表面喷涂UV油墨层12；然后以UV固化的方式使其UV油墨层12固化。形成如图3中c所示的互连条1和汇流条4颜色完全与电池片2颜色相同。所述UV油墨层12的颜色与电池片的颜色相同。所述加热方式固化采用UV灯24照射的方式固化。UV油墨层12组成包括有机或无机染料，环氧丙烯酸脂、聚酯丙烯酸脂、丙烯酸氨基甲酸脂等预聚物、光引发剂及稀释剂等组成。
参见图2所示，喷涂设备20位于电池片阵列的上方，喷涂设备20包括可以移动的安装平台21、喷头22、管路23和UV灯24，所述喷头22和UV灯24固定连接在安装平台21上，且管路23连接喷头22。所述UV灯的瓦数为所述UV灯的瓦数为在30w-200w之间，可装设多套灯组，设在喷头22的前后两侧，以提高固化效率。首先预设安装平台21的行进路线，参见图3中b所示，剖面线部分标记为14的路线就是安装平台21的行进路线，可以完全覆盖互连条1和汇流条4的位置，喷头22的选择也需要多方位考虑，经过反复的实验，喷头22的喷射宽度与互连条1和汇流条4的宽度一致，安装平台21的喷涂速度为10～20m2/hr之间，以便UV灯24能够完全固化油墨，当喷涂完成后，UV灯24同时对喷涂路线上的油墨进行固化处理，形成如图3中c的成品，生产效率得到大大提高。
