Embodiment Construction

[0074] The present invention will be further described below in conjunction with accompanying drawing.

[0075] 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 as follows figure 1 As shown, it includes six or twelve cells A and multiple welding ribbons B (when six cells are connected to form a battery string, the cells used are full-piece cells; twelve 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 welding ribbons B in one set, and they are arranged along the direction vertical 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 shee...

Abstract

The invention discloses a two-stage welding type IBC solar cell string welding device and a welding method thereof. Compared with a conventional series welding machine, the IBC battery needs to be covered and fixed by a net pressing clamp because the position of the metal wire is fixed by a rear battery piece and the IBC battery cannot reach the point. The device comprises a light welding module,a final welding module, a battery string transfer module, a light welding base and a final welding base. The light welding module comprises a welding strip feeding device, a welding strip transferringdevice, a light welding device, a clamp backflow device, a third battery conveyor, a clamp conveyor and a pressing positioning clamp. The final welding module comprises a final welding base, a finalwelding conveyor, a final welding pushing and lifting device and six pressure welding devices. The final welding pushing and lifting device comprises a pushing and lifting frame and a pushing and lifting electric cylinder. According to the invention, the battery piece and the solder strip are preliminarily welded through the light welding module, and then the battery piece and the solder strip arereliably welded through the final welding module; and therefore, full automation of battery piece production is realized on the premise of hardly influencing the quality of the battery pieces.

Description

technical field [0001] The invention belongs to the technical field of solar cell production equipment, and in particular relates to a two-stage welding type IBC solar cell string welding device and a welding 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 c...
