太阳能电池组件生产流程英文解说

 

中文:太阳能电池组件生产工艺

组件线又叫封装线,封装是太阳能电池生产中的关键步骤,没有良好的封装工艺,多好的电池也生产不出好的组件板。电池的封装不仅可以使电池的寿命得到保证,而且还增强了电池的抗击强度。产品的高质量和高寿命是赢得可客户满意的关键,所以组件板的封装质量非常重要。

工艺流程如下:

1、电池检测——2、正面焊接—检验—3、背面串接—检验—4、敷设(玻璃清洗、材料切割、玻璃预处理、敷设)——5、层压——6、去毛边(去边、清洗)——7、装边框(涂胶、装角键、冲孔、装框、擦洗余胶)——8、焊接接线盒——9、高压测试——10、组件测试—外观检验—11、包装入库;

1.2工艺简介:

在这里只简单的介绍一下工艺的作用,给大家一个感性的认识,具体内容后面再详细介绍:

1、电池测试:由于电池片制作条件的随机性,生产出来的电池性能不尽相同,所以为了有效的将性能一致或相近的电池组合在一起,所以应根据其性能参数进行分类;电池测试即通过测试电池的输出参数(电流和电压)的大小对其进行分类。以提高电池的利用率,做出质量合格的电池组件。

2、 正面焊接:是将汇流带焊接到电池正面(负极)的主栅线上,汇流带为镀锡的铜带,我们使用的焊接机可以将焊带以多点的形式点焊在主栅线上。焊接用的热源为一个红外灯(利用红外线的热效应)。焊带的长度约为电池边长的2倍。多出的焊带在背面焊接时与后面的电池片的背面电极相连。(我们公司采用的是手工焊接)

3、背面串接:背面焊接是将36片电池串接在一起形成一个组件串,我们目前采用的工艺是手动的,电池的定位主要靠一个膜具板,上面有36个放置电池片的凹槽,槽的大小和电池的大小相对应,槽的位置已经设计好,不同规格的组件使用不同的模板,操作者使用电烙铁和焊锡丝将“前面电池”的正面电极(负极)焊接到“后面电池”的背面电极(正极)上,这样依次将36片串接在一起并在组件串的正负极焊接出引线。

4、层压敷设:背面串接好且经过检验合格后,将组件串、玻璃和切割好的EVA 、玻璃纤维、背板按照一定的层次敷设好,准备层压。玻璃事先涂一层试剂(primer)以增加玻璃和EVA的粘接强度。敷设时保证电池串与玻璃等材料的相对位置,调整好电池间的距离,为太阳能电池组件层压打好基础。(敷设层次:由下向上:玻璃、EVA、电池、EVA、玻璃纤维、背板)。

5、组件层压:将敷设好的电池放入层压机内,通过抽真空将组件内的空气抽出,然后加热使EVA熔化将电池、玻璃和背板粘接在一起;最后冷却取出组件。层压工艺是组件生产的关键一步,层压温度层压时间根据EVA的性质决定。我们使用快速固化EVA时,层压循环时间约为25分钟。固化温度为150℃。

6、修边:层压时EVA熔化后由于压力而向外延伸固化形成毛边,所以层压完毕应将其切除。

7、 装框:类似与给玻璃装一个镜框;给玻璃组件装铝框,增加组件的强度,进一步的密封电池组件,延长电池的使用寿命。边框和玻璃组件的缝隙用硅酮树脂填充。各边框间用角键连接。

8、焊接接线盒:在组件背面引线处焊接一个盒子,以利于电池与其他设备或电池间的连接。

9、高压测试:高压测试是指在组件边框和电极引线间施加一定的电压,测试组件的耐压性和绝缘强度,以保证组件在恶劣的自然条件(雷击等)下不被损坏。

10、组件测试:测试的目的是对电池的输出功率进行标定,测试其输出特性,确定组件的质量等级。


英文:

Solar cell module production process

 

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.

 

Process is as follows:

 

1, the battery test - 2, positive Welding - Inspection -3, on the back of cascading - Inspection -4, laying (glass cleaning, material cutting, glass pre-processing, laying) - 5, laminating - 6, to flash ( to the side, cleaning) - 7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) - 8, the welding junction box - 9, high-pressure test - 10, component testing -- -11 appearance inspection, packaging and storage;

 

1.2 Process Description:

 

Here only a brief look at the role of technology, give us an emotional understanding of the specific content of a further detail later:

 

1, the battery test: Because the randomness of the battery-chip manufacturing conditions, the production out of battery performance is different, we will be for the effective performance of identical or similar battery together, it should be classified according to their performance parameters; battery test that is by testing the battery output parameters (current and voltage) of the size of its classification. To improve the utilization of the battery to make the battery components of acceptable quality.

 

2, positive welding: It's convergence with soldered to the battery positive (negative) of the main gate line, convergence zone for the tinned copper strip, we use a welding machine can weld with a multi-point in the form of spot welding on the main gate Online. Welding heat source for an infrared lamp (using infrared thermal effect). Welding with the length of the side length of about 2 times the battery. More welding belt behind the back of welding with electrodes connected to the back of the battery piece. (Our company uses a manual welding)

 

3, on the back of concatenation: back of the weld is 36 cells cascaded together to form a component of the string, we are currently used process is manual, the battery depends mainly on the positioning of a membrane with plate 36 placed above the battery film grooves, groove size and battery size correspond to the location of tank has been designed well, different specifications of the components use a different template, the operator use electric soldering iron and solder wire will "in front of the battery," the positive electrode (cathode) Welding to the "behind the battery" on the back electrode (cathode), so that in turn will be 36 series with the component string together and welded out of positive and negative leads.

 

4, laminated lay: on the back of a good tandem and tested after passing the component string, glass and cut a good EVA, glass fiber, backplane according to a certain level, laying a good preparation for lamination. Glass pre-coated layer of reagent (primer) in order to increase the bonding strength of glass and EVA. When installed to ensure the battery strings and glass and other materials relative position, adjusting the distance between the battery, in order to laminate lay a solid foundation. (Laying of levels: from the bottom up: glass, EVA, cell, EVA, glass fiber, backplane).

 

5, component lamination: a good battery will be laid into the laminating machine, through the vacuum component of the air out, and then heated to melt the EVA batteries, glass and back bonding together; the final cooling out components. Lamination process is a key step in component production, lamination temperature lamination time, according to the nature of EVA. We use the fast-curing EVA, the lamination cycle time is about 25 minutes. Curing temperature of 150 ℃.

 

6, trimming: laminated EVA melt when the pressure of reaching out after curing due to the formation of flash, so it should be removed laminated finish.

 

7, fitted box: similar to the glass mounted to a frame; to the glass component mounted aluminum frame to increase the intensity of the component, further sealing the battery components, longer battery life. Borders and glass components of the gap filled with silicone resin. The border between the connection with the angle button.

 

8, the welding junction box: In the component lead at the back of a box welded to facilitate the battery and other equipment or connections between cells.

 

9, high-pressure test: high-pressure test is defined as components of the border and the electrode lead a certain voltage is applied between the test component of the pressure resistance and dielectric strength to ensure that components in harsh natural conditions (lightning, etc.) will not be damaged under the .

 

10, component testing: the test objective is to calibrate the battery output power to test its output characteristics, determine the quality grade components.
