具体实施方式
为使本领域的技术人员更好地理解本发明的技术方案，首先对本发明的发明人正在研究的一种太阳能电池的封装工艺进行介绍。在这种太阳能电池的封装工艺中，首先需要将互联条与多个电池片敷设，并将敷设后的互联条与多个电池片放入焊接腔室中，通过焊接腔室中的焊接装置将互联条与多个电池片焊接，使多个电池片串联形成电池串。之后，将电池串从焊接腔室内取出，并准备敷设有第一胶膜层的玻璃板，将多个电池串敷设在第一胶膜层上，且将汇流条与多个电池串敷设，之后，将敷设完的玻璃板、第一胶膜层、汇流条和多个电池串放入焊接腔室中，通过焊接装置将汇流条与多个电池串焊接，使多个电池串并联形成电池片组，并使电池片组通过第一胶膜层与玻璃板预粘结。之后，将电池片组、第一胶膜层和玻璃板从焊接腔室内取出，在电池片组的背面依次敷设第二胶膜层和背板，再将敷设完的电池片组、第一胶膜层、玻璃板、第二胶膜层和背板放入层压腔室，通过层压腔室中的层压装置对电池片组、第一胶膜层、玻璃板、第二胶膜层和背板进行层压焊接，从而完成太阳能电池的封装层压工艺。
对于这种太阳能电池的封装工艺，由于需要在焊接腔室和层压腔室两个独立腔室中，通过焊接装置和层压装置分别进行焊接，因此，会造成太阳能电池的封装效率较低，并造成太阳能电池的封装不确定性增加。此外，由于目前焊接装置的结构较为复杂，且焊接良率较低，从而导致太阳能电池的产能和良率较低。
为使本领域的技术人员更好地理解本发明的技术方案，下面结合附图来对本发明提供的封装层压装置、设备及工艺方法进行详细描述。
如图1-图5所示，本发明实施例提供一种封装层压装置，包括第一层压部件1、第二层压部件2和微波组件3，第一层压部件1和第二层压部件2相对设置，且可在二者相对的方向上相互靠近或远离，用于对电池层压组件5进行层压焊接，微波组件3设置在第一层压部件1和/或第二层压部件2 上，用于通过第一层压部件1和/或第二层压部件2将微波组件3产生的微波传输至电池层压组件5，以利用微波对电池层压组件5进行预焊接。
这样借助微波组件3可以将电池片组51件中的多个电池片511焊接在一起，而借助第一层压部件1和第二层压部件2可以对电池层压组件5进行层压焊接，从而使得本发明实施例提供的封装层压装置，兼具焊接装置和层压装置两个装置的功能，继而在进行太阳能电池的封装工艺时，无需借助焊接装置和层压装置分别进行焊接和层压，而仅需借助本发明实施例提供的封装层压装置，就既可以对电池层压组件5进行预焊接，将多个电池片511焊接在一起，又可以对电池层压组件5进行层压焊接，从而能够提高太阳能电池的产能及良率。
下面以如图5所示的一种电池层压组件5为例，对本发明实施例提供的封装层压装置进行说明。在借助本发明实施例提供的封装层压装置对电池层压组件5进行层压焊接之前，需要先准备电池层压组件5，例如，在实际应用中，可以先将互联条与多个电池片511敷设，形成敷设但未焊接的电池串，并准备敷设有第一胶层52的透明面板53，再将多个敷设但未焊接的电池串敷设在第一胶层52上，且将汇流条与多个电池串敷设，从而在第一胶层52上形成敷设但未焊接的电池片组51。之后，可以在电池片组51的背面依次敷设第二胶层54和背板55，也就是说，可以先在电池片组51的背面敷设第二胶层54，再在第二胶层54背离电池片组51的一面敷设背板55，进而形成电池层压组件5。
之后，可以将电池层压组件5放入设置有本发明实施例提供的封装层压装置的封装层压腔室中，并使封装层压装置的第一层压部件1和第二层压部件2分别位于电池层压组件5的正面和背面，且使第一层压部件1和第二层压部件2分别与电池层压组件5的正面和背面分离，即，使第一层压部件1和第二层压部件2分别与电池层压组件5的正面和背面之间具有间距(如图 1和图2所示)，也就是说，第一层压部件1和第二层压部件2分别与透明面板53和背板55分离，即，使第一层压部件1和第二层压部件2分别与透明面板53和背板55之间具有间距。
之后，可以通过设置在第一层压部件1和/或第二层压部件2上的微波组件3产生微波并将微波传输向第一层压部件1和/或第二层压部件2，而第一层压部件1和/或第二层压部件2可以将微波传输向电池层压组件5，也就是说，若第一层压部件1上设置有微波组件3，则微波组件3可以产生微波并将微波传输向第一层压部件1，第一层压部件1可以将微波传输向电池层压组件5，若第二层压部件2上设置有微波组件3，则微波组件3可以产生微波并将微波传输向第二层压部件2，第二层压部件2可以将微波传输向电池层压组件5，若第一层压部件1和第二层压部件2上均设置有微波组件3，则第一层压部件1和第二层压部件2上的微波组件3可以分别产生微波并将微波分别传输向第一层压部件1和第二层压部件2，第一层压部件1和第二层压部件2均可以将微波传输向电池层压组件5。微波能够使电池层压组件5中具有可导电材料512的部件(例如，汇流条、互联条和电池片511的栅线)产生电磁涡流，以使例如汇流条、互联条和电池片511的栅线的温度升高，从而使互联条能够与电池片511的栅线预焊接，以使多个电池片511能够串联形成电池串，并使互联条能够与汇流条预焊接，以使多个电池串能够并联形成电池片组51，进而实现对电池层压组件5的预焊接。
之后，可以使第一层压部件1和第二层压部件2在二者相对的方向上相互靠近，分别与电池层压组件5的正面和背面接触(如图3和图4所示)，也就是说，第一层压部件1和第二层压部件2分别与透明面板53和背板55接触，之后，可以借助第一层压部件1和第二层压部件2对电池层压组件5进行层压焊接，将例如透明面板53、第一胶层52、电池片组51、第二胶层54和背板55压紧并焊接在一起。
可见，本发明实施例提供的封装层压装置，既可以对电池层压组件5进行预焊接，将多个电池片511焊接在一起，又可以对电池层压组件5进行层压焊接，从而能够提高太阳能电池的产能及良率。并且，通过在对电池层压组件5进行层压焊接之前，先对电池层压组件5进行预焊接，可以避免电池层压组件5中具有可导电材料512的部件因受到第一层压部件1和第二层压部件2的挤压，而相对于电池片511发生移动，影响具有可导电材料512的部件与电池片511的交联，从而能够提高太阳能电池的良率。
在实际应用中，在第一层压部件1和第二层压部件2分别与电池层压组件5的正面和背面接触，对电池层压组件5进行层压焊接时，微波组件3也可以产生微波，以利用微波对电池层压组件5进行焊接，从而能够进一步提高太阳能电池的产能。
但是，本发明实施例提供的封装层压装置并不限于对上述敷设有汇流条和互联条的电池层压组件5进行层压焊接，例如，在准备电池层压组件5时，也可以先准备敷设有第一胶层52的透明面板53，并将多个电池片511敷设在第一胶层52上，从而在第一胶层52上形成敷设但未焊接电池片组51，之后，可以在电池片组51上涂布导电胶，并在电池片组51的背面依次敷设第二胶层54和背板55，从而形成电池层压组件5，在这种电池层压组件5中并未敷设汇流条和互联条，而是通过涂布在电池片组51上的导电胶，来替代汇流条和互联条。
对于涂布有导电胶的电池层压组件5来说，传输至电池层压组件5的微波可以使电池层压组件5中具有可导电材料512的部件(例如，导电胶和电池片511的栅线)产生电磁涡流，以使例如导电胶和电池片511的栅线的温度升高，对导电胶进行烘干，从而使导电胶能够与电池片511的栅线预焊接，以使多个电池片511能够串联形成电池串，并使导电胶能够相互预焊接，以使多个电池串能够并联形成电池片组51，进而实现对涂布有导电胶的电池 层压组件5的预焊接。
可选的，汇流条可以包括镀锡铜带或铝带。
可选的，互联条可以包括镀锡铜带或铝带。
在实际应用中，汇流条和互联条可以统称为焊带。
在实际应用中，透明面板53可以作为太阳能电池的光线入射面。
可选的，透明面板53可以为玻璃板。
可选的，背板55可以为透明或不透明。
可选的，透明的背板55可以为玻璃板。
可选的，第二胶层54可以为透明或不透明。
可选的，导电胶可以包括树脂导电胶、银浆导电胶或银铝浆导电胶。
可选的，层压焊接的时间可以为500s-900s。
如图1和图3所示，在本发明一实施例中，第一层压部件1和第二层压部件2上可以均设置有微波组件3。这样可以提高对电池层压组件5进行预焊接的效率，从而能够进一步提高太阳能电池的产能。
如图1和图3所示，在本发明一实施例中，微波组件3可以包括微波发生部件31和微波传输部件32，微波发生部件31能够与供电设备(图中未示出)电连接，用于在通电时产生微波，微波传输部件32与微波发生部件31电连接，并与第一层压部件1和/或第二层压部件2电连接，用于将微波传输至第一层压部件1和/或第二层压部件2。
也就是说，供电设备可以向微波发生部件31供电，微波发生部件31在通电时可以产生微波，并将微波传输至微波传输部件32，当微波传输部件32与第一层压部件1电连接时(即，微波组件3设置在第一层压部件1上)，微波传输部件32可以将波传输至第一层压部件1，以使微波通过第一层压部件1传输向电池层压组件5，当微波传输部件32与第二层压部件2电连接时(即，微波组件3设置在第二层压部件2上)，微波传输部件32 可以将波传输至第二层压部件2，以使微波通过第二层压部件2传输向电池层压组件5，当微波传输部件32与第一层压部件1和第二层压部件2均电连接时(即，微波组件3设置在第一层压部件1和第二层压部件2上)，微波传输部件32可以将波传输至第一层压部件1和第二层压部件2，以使微波通过第一层压部件1和第二层压部件2传输向电池层压组件5。
在本发明一实施例中，微波发生部件31可以包括磁控管。
在本发明一实施例中，微波传输部件32可以包括波导管。
在本发明一实施例中，微波组件3可以还包括微波调频部件(图中未示出)，微波发生部件31通过微波调频部件与供电设备电连接，微波调频部件用于调节微波发生部件31产生的微波的频率。这样可以提高封装层压装置的适用范围和使用灵活性。
例如，在对电池层压组件5进行预焊接时，可以借助微波调频部件将微波的频率调节至第一预设频率，第一预设频率的微波能够使电池层压组件5中具有可导电材料512的部件产生电磁涡流，以使具有可导电材料512的部件的温度升高，从而实现对电池层压组件5的预焊接。而在电池层压组件5预焊接之后，可以借助微波调频部件将微波的频率调节至第二预设频率，第二预设频率的微波能够使电池层压组件5中的第一胶层52和第二胶层54的温度升高，从而在对电池层压组件5进行层压焊接时，能够提高层压焊接的效率，进而能够进一步提高太阳能电池的产能。
通过在使第一胶层52和第二胶层54的温度升高之前，对电池层压组件5进行预焊接，可以避免电池层压组件5中具有可导电材料512的部件因受到第一胶层52和第二胶层54的温度升高而产生型变，影响具有可导电材料512的部件与电池片511的交联，从而能够提高太阳能电池的良率。
在本发明一实施例中，微波的频率可以包括5GHz-13GHz和900MHz-5GHz。其中，5GHz-13GHz可以作为微波的第一预设频率， 900MHz-5GHz可以作为微波的第二预设频率。

也就是说，变压部件33可以分别与微波发生部件31和供电设备电连接，供电设备输出的电压通过变压部件33的调节加载至微波发生部件31。
可选的，变压部件33可以为变压器。
在本发明一实施例中，第一层压部件1和/或第二层压部件2上可以设置有加热组件(图中未示出)，加热组件用于通过对电池层压组件5进行加热，来对电池层压组件5进行焊接。
也就是说，在对电池层压组件5进行层压焊接时，加热组件可以对电池层压组件5进行加热，从而实现对电池层压组件5的焊接。
可选的，加热组件可以包括油加热件、电加热件、油电混合加热件、红外加热灯管和激光加热件中的任意一种。
如图3所示，在本发明一实施例中，封装层压装置可以还包括抽气组件4，抽气组件4与第一层压部件1和第二层压部件2之间的空间连通，用于通过对第一层压部件1和第二层压部件2之间的空间进行抽气，来对电池层压组件5进行抽气。
在实际应用中，在电池层压组件5预焊接之后且层压焊接之前，或者自预焊接之后至层压焊接完成，可以借助抽气组件4对电池层压组件5进行抽气(可选的，时间可以为200s-400s)，以抽出第一胶层52和第二胶层54的气泡，提高电池层压组件5在层压焊接时的交联率及可靠性，从而能够进一步提高太阳能电池的良率。
可选的，抽气组件4可以包括抽气泵41和抽气管42，抽气管42的一端与抽气泵41连通，另一端与第一层压部件1和第二层压部件2之间的空 间连通，从而使抽气泵41能够通过抽气管42对第一层压部件1和第二层压部件2之间的空间进行抽气。
本发明实施例还提供一种封装层压设备，包括封装层压腔室和如本发明实施例提供的封装层压装置，封装层压装置设置在封装层压腔室中，用于对电池层压组件5进行封装层压工艺。
