Problems solved by technology

[0002] In the manufacturing process of crystalline silicon solar cell modules, the cells and ribbon must be welded together. The welding of cells has a key influence on the production efficiency and quality stability of crystalline silicon solar cell components. The current welding method of solar cells It is manual welding, and electric soldering iron is usually used for manual welding. The production efficiency is low and the quality stability is poor. The intermediate frequency heat conduction heating welding quality is stable, and the induction heating is rapid and efficient.

Embodiment Construction

[0016] The present invention will be further elaborated below in conjunction with accompanying drawing:

[0017] Such as figure 1 and figure 2 In the solar battery sheet welding method shown, first, the battery sheet 3 and the welding ribbon 2 are placed on the preheating plate 1, and the battery sheet 3 and the welding ribbon 2 are welded by heating the welding device, and the welding device includes a high-frequency generator 4. The metal rod 6 and the induction circuit 5 connecting the high-frequency generator 4 and the metal rod 6 , the induction circuit 5 is arranged around the metal rod 6 .

[0018] The induction loop 5 is composed of a plurality of helical coils and connecting wires, the helical coils are arranged around the metal rod 6, and the helical coils are wound at least once, and the number of turns of the helical coils can determine the size of the eddy current effect, The more coils are wound, the greater the eddy current effect will be, which can effective...

Abstract

The invention relates to a welding method of a crystalline silicon solar energy battery plate, which is used for welding a battery plate and a welding strip in the manufacturing process of a crystalline silicon solar energy battery plate component and is suitable for manufacturing the crystalline silicon solar energy battery plate component. The welding method of the solar energy battery plate comprises the following steps: firstly placing the battery plate and the welding strip on a preheating board and welding the battery plate and the welding strip through the heating of a welding device; the welding device comprises a current generator, a metal bar and an induction loop connected between a high-frequency generator and the metal bar; and the induction loop is arranged on the periphery of the metal bar in a surrounding manner. The welding method can realize the automation welding by using eddy-current effect heating to replace the traditional manual welding and has the advantages of quick heating speed, good welding quality and high production efficiency.
