（1）電池測試

(1) Battery test

由于電池片制作條件的隨機性，生產(chǎn)出來的電池性能不盡相同，所以天能瓦認為，為了有效的將性能一致或相近的電池組合在一起，所以應根據(jù)其性能參數(shù)進行分類；電池測試即通過測試電池的輸出參數(shù)（電流和電壓）的大小對其進行分類。以提高電池的利用率，做出質(zhì)量合格的電池組件。

Due to the randomness of the manufacturing conditions of the battery chips, the performance of the batteries produced are different, so Tiannengwa believes that in order to effectively combine the batteries with the same or similar performance, they should be classified according to their performance parameters; The battery test is to classify the battery by testing its output parameters (current and voltage). In order to improve the utilization rate of battery and make qualified battery components.

（2）正面焊接

(2) Front welding

將匯流帶焊接到電池正面（負極）的主柵線上，匯流帶為鍍錫的銅帶，我們使用的焊接機可以將焊帶以多點的形式點焊在主柵線上。焊接用的熱源為一個紅外燈（利用紅外線的熱效應）。焊帶的長度約為電池邊長的2倍。多出的焊帶在背面焊接時與后面的電池片的背面電極相連。

The bus bar is welded to the main grid line on the front (negative) side of the battery. The bus bar is tinned copper strip. The welding machine we use can spot weld the bus bar on the main grid line in the form of multiple points. The heat source for welding is an infrared lamp (using the thermal effect of infrared ray). The length of the welding strip is about twice the length of the battery side. The extra welding strip is connected with the back electrode of the rear battery panel during the back welding.

（3）背面串接

(3) Back serial connection

背面焊接是將電池串接在一起形成一個組件串，采用的工藝是手動的，電池的定位主要靠一個膜具板，上面有放置電池片的凹槽，槽的大小和電池的大小相對應，槽的位置已經(jīng)設計好，不同規(guī)格的組件使用不同的模板，操作者使用電烙鐵和焊錫絲將“前面電池”的正面電極（負極）焊接到“后面電池”的背面電極（正極）上，這樣依次串接在一起并在組件串的正負極焊接出引線。

The back welding is to connect the batteries in series to form a component string. The process is manual. The positioning of the battery mainly depends on a membrane plate, on which there is a groove for placing the battery. The size of the groove corresponds to the size of the battery. The position of the groove has been designed, and different modules of different specifications use different templates, The operator uses an electric soldering iron and soldering wire to weld the front electrode (negative electrode) of the "front battery" to the back electrode (positive electrode) of the "rear battery", so as to connect them in series and weld the lead wire at the positive and negative electrodes of the assembly string.

（4）層壓敷設

(4) Laminated laying

背面串接好且經(jīng)過檢驗合格后，將組件串、玻璃和切割好的EVA、玻璃纖維、背板按照一定的層次敷設好，準備層壓。玻璃事先涂一層試劑（primer）以增加玻璃和EVA的粘接強度。敷設時保證電池串與玻璃等材料的相對位置，調(diào)整好電池間的距離，為層壓打好基礎。（敷設層次：由下向上：鋼化玻璃、EVA、電池片、EVA、玻璃纖維、背板）。

After the back side is connected in series and passed the inspection, lay the component string, glass and cut EVA, glass fiber and back plate in a certain layer and prepare for lamination. The glass is coated with a layer of reagent in advance to increase the bonding strength of glass and EVA. During laying, ensure the relative position of battery string and glass and other materials, adjust the distance between batteries, and lay a good foundation for lamination. (Laying level: from bottom to top: tempered glass, EVA, battery, EVA, glass fiber, back plate).

（5）組件層壓

(5) Component lamination

將敷設好的電池放入層壓機內(nèi)，通過抽真空將組件內(nèi)的空氣抽出，然后加熱使EVA熔化將電池、玻璃和背板粘接在一起；冷卻取出組件。層壓工藝是組件生產(chǎn)的關鍵一步，層壓溫度層壓時間根據(jù)EVA的性質(zhì)決定。我們使用快速固化EVA時，層壓循環(huán)時間約為25分鐘。固化溫度為150℃。

Put the laid battery into the laminator, extract the air in the module by vacuuming, and then heat it to melt the EVA to bond the battery, glass and backplane together; Cool down and take out the assembly. The lamination process is a key step in the production of components. The lamination temperature and lamination time are determined by the nature of EVA. When we use rapid curing EVA, the lamination cycle time is about 25 minutes. The curing temperature is 150 ℃.

（6）修邊

(6) Trimming

層壓時EVA熔化后由于壓力而向外延伸固化形成毛邊，所以層壓完畢應將其切除。

During lamination, EVA will extend outward and solidify to form burr due to pressure after melting, so it should be cut off after lamination.

（7）裝框

(7) Framing

類似與給玻璃裝一個鏡框；給玻璃組件裝鋁框，增加組件的強度，進一步的密封電池組件，延長電池的使用壽命。邊框和玻璃組件的縫隙用硅酮樹脂填充。各邊框間用角鍵連接。

It is similar to installing a glass frame; Install aluminum frame on the glass module to increase the strength of the module, further seal the battery module and extend the service life of the battery. The gap between the frame and the glass component is filled with silicone resin. The borders are connected with corner keys.

（8）焊接接線盒

(8) Welded junction box

在組件背面引線處焊接一個盒子，以利于電池與其他設備或電池間的連接。

Weld a box at the lead on the back of the module to facilitate the connection between the battery and other devices or batteries.

（9）高壓測試

(9) High voltage test

高壓測試是指在組件邊框和電極引線間施加一定的電壓，測試組件的耐壓性和絕緣強度，以保證組件在惡劣的自然條件（雷擊等）下不被損壞。

High voltage test refers to applying a certain voltage between the frame of the module and the electrode lead to test the withstand voltage and insulation strength of the module, so as to ensure that the module will not be damaged under harsh natural conditions (lightning, etc.).

（10）組件測試

(10) Component test

測試的目的是對電池的輸出功率進行標定，測試其輸出特性，確定組件的質(zhì)量等級。主要就是模擬太陽光的測試Standardtestcondition（STC），一般一塊電池板所需的測試時間在7-8秒左右。更多相關內(nèi)容就來我們網(wǎng)站http://51lib.com.cn咨詢！
