technical field

The utility model relates to the field of welding technology, in particular to a full-automatic serial welding equipment capable of welding four-grid and five-grid solar cells. the

Background technique

In the manufacturing process of crystalline silicon solar cell modules, the cells must be welded into strings, and the main grid lines of the cells have two grid lines, three grid lines, four grid lines, five grid lines, etc., different grid line cells and Cell string welding has a key impact on the production efficiency and quality stability of crystalline silicon solar cell components. Currently, crystalline silicon solar cells are welded in two ways. The first is manual welding, which is usually used for manual welding. Welding with an electric soldering iron, the more busbars of the cell, the lower the production efficiency and the worse the quality stability; the second is to use a fully automatic welding machine for welding, and the welding of the fully automatic welding machine mainly uses infrared heating welding. The infrared heating welding method has the following problems: the welding speed is slow, the battery is easily deformed when heated, and the battery is more likely to be damaged due to the increase in the number of bus bars of the battery, and the energy consumption is also large. Although the current automatic welding machine adopting electromagnetic heating welding method in the market can solve the existing big problem of energy consumption, the current automatic welding machine adopting electromagnetic heating welding method still has the following problems: slow welding speed and easy damage of batteries . the
