Device for welding bus bar of solar cell

Abstract

The present disclosure discloses a device for welding a bus bar of a solar cell, including a welding platform, a laser, a sensor and a laser adjustment mechanism. The laser is disposed over the welding platform. The laser adjustment mechanism is connected to the laser. The surface of the welding platform is provided with the sensor. In the device for welding a bus bar of a solar cell according to the present disclosure, laser welding is employed instead of the conventional manual soldering iron welding and resistance heating welding, and the power of the laser can be adjusted as desired with the laser adjustment mechanism, thereby better controlling the accuracy and uniformity of the welding temperature of the bus bar. Compared with the related art, it can improve the welding quality of the bus bar, avoid the positional deviation between the bus bar and the drain bar, reduce the bad phenomenon such as the false welding or the missing welding and improve the overall performance of the photovoltaic module.
