The solar panel curing line is also referred to as a packaging line when it is used. To some extent, its packaging is a key step in the production of solar cells. Without a good packaging process, a good battery can not produce a good component board. The battery package not only ensures the battery life, but also enhances the battery's impact strength. The high quality and longevity of the product is the key to winning customer satisfaction, so the package quality of the component board is very important.
The main introduction of solar panel curing line
1. Battery test: Due to the randomness of the production conditions of the battery, the performance of the produced battery is not the same. Therefore, in order to effectively combine the batteries with the same performance or similar performance, the battery should be classified according to its performance parameters; The battery is sorted by testing the output parameters (current and voltage) of the battery. In order to improve the utilization rate of the battery, a qualified battery assembly is produced.
2, front welding: is to weld the busbar to the main grid line of the front (negative) of the battery, the busbar is tinned copper strip, we use the welding machine to weld the strip in the form of multiple points on the main grid on-line. The heat source for welding is an infrared lamp (using the thermal effect of infrared rays). The length of the ribbon is approximately twice the length of the side of the battery. The extra solder ribbon is attached to the back electrode of the rear cell when soldered on the back side. (Our company uses manual welding)
3, back series: back welding is to connect 36 pieces of batteries together to form a component string, the current process we use is manual, the battery is mainly positioned by a membrane board, there are 36 recesses on the top of the battery The slot, the size of the slot corresponds to the size of the battery, the position of the slot has been designed, the different specifications of the components use different templates, the operator uses the soldering iron and solder wire to solder the front electrode (negative) of the "front battery" to " On the back electrode (positive electrode) of the rear battery, 36 pieces are sequentially connected in series and the leads are soldered to the positive and negative electrodes of the component string.
