Then, the first transfer device 50 moving on one side of the work rail 20 picks up the solar cell C of the ribbon R to be soldered from the cell stage 14 and conveys and places the solar cell C to the cell station 30, and then the second transfer device 70 moving on the other side of the work rail 20 picks up the solar cell C placed on the cell station 30, and thereafter, the work rail 20 advances and retreats along the base rail 21, and the second transfer device 70 arranges the picked-up solar cell C on the glass substrate G on the conveying stage 90 at a constant interval. By repeating the above process, 60 solar cells can be arranged on the glass substrate G.

After the arrangement of the solar cell pieces is completed, as shown in fig. 14, the conveyor lifting unit 93 lifts the glass conveyor 92 to separate the glass substrate G from the glass table 91, and then the belt 92d is driven to convey the glass substrate G to the next step.

As described above, according to the present invention, a series of operations related to picking, conveying, and welding of the solar cell sheets C and the ribbons R can be automatically completed, and the solar cell module M in which a plurality of ribbons R are connected to each other by the solar cell sheets C can be rapidly and accurately manufactured, so that productivity can be improved.

Further, the thin strip R can be uniformly soldered to the finger electrodes E, and thus a solar cell module having a certain quality can be manufactured.

Moreover, since the welding is automatically performed, the operator is not exposed to harmful welding steam, and the welding device has the function and effect of improving the working environment.

While the invention has been described with reference to one embodiment shown in the drawings, this is by way of example only and it is to be understood that various modifications and other equivalent embodiments may be made by those skilled in the art.
