Embodiment Construction

[0081] The present invention will be further described below in conjunction with accompanying drawing.

[0082] Such as figure 1 As shown, the present invention is used to produce "IBC solar cell strings". The structure of the IBC solar cell string is shown in Figure 1, including six or twelve cells A and multiple ribbons B (when six cells are connected into a cell string, the cells used are full-sheet cells; ten When two cells are connected to form a battery string, the cells used are half-cell cells). Each battery sheet A is arranged at equal intervals in turn. Two adjacent cells A are connected by a set of ribbons B. There are four ribbons B in one group, and they are arranged along the direction perpendicular to the arrangement of battery sheets. The two ends of the four welding ribbons B respectively cover the opposite edges of the two adjacent battery sheets A. Adjacent two groups of soldering strips are staggered; therefore, any battery sheet A is connected with ei...

Abstract

The invention discloses an IBC solar cell string welding strip welding production line and a production method thereof. Compared with the conventional stringer using the last battery piece to fix the position of the metal wire, the IBC battery cannot do this, and needs to use the clamp to cover and fix it. The invention relates to an IBC solar battery string ribbon welding production line, which comprises a battery arrangement module, a ribbon adding module, a final welding module and a battery string transfer module. The battery arrangement module, the ribbon adding module, and the final welding module are arranged in sequence. The battery string transfer module is arranged at the output end of the ribbon adding module, and transfers the battery string output from the ribbon adding module to the final welding module. The ribbon adding module includes a middle frame, a ribbon feeding device, a ribbon transfer device, a light soldering device, a jig reflow device, a third battery conveyor, a jig conveyor, and a press positioning jig. The invention can realize full-automatic cell arrangement, preliminary welding and final welding.

Description

technical field [0001] The invention belongs to the technical field of solar cell production equipment, and in particular relates to an IBC solar cell string ribbon welding production line and a production method thereof. Background technique [0002] IBC battery (full back electrode contact crystalline silicon photovoltaic cell) is a technology that moves both the positive and negative metal contacts to the back of the cell, so that the front of the cell facing the sun is completely black, and the front of most photovoltaic cells is completely invisible. metal wires. This not only brings more effective power generation area to users, but also helps to improve power generation efficiency, and the appearance is also more beautiful. The biggest feature of the IBC battery is that the PN junction and metal contact are on the back of the battery, and the front is not affected by the shielding of the metal electrode, so it has a higher short-circuit current Jsc, and the back can ...
