Embodiment Construction

[0055] The present invention will be further described below in conjunction with accompanying drawing.

[0056] 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 sequence. 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 ...

Abstract

The invention discloses an IBC solar cell string light welding device and a welding method thereof. Compared with a conventional series welding machine through which the position of a metal wire is fixed through a rear battery piece, IBC batteries cannot achieve the effect, and a net pressing clamp is needed to perform covering fixing. The light welding device comprises a rack, a welding strip feeding device, a welding strip transferring device, a light welding device body, a clamp returning device, a battery conveyor, a clamp conveyor and a pressing positioning clamp; the clamp conveyor is located on one side of the battery conveyor; the welding strip feeding device is located below the output end of the clamp conveyor; the welding strip transferring device is located above the input endof the battery conveyor and the output end of the clamp conveyor; and the welding strip transferring device, the light welding device body and the clamp returning device are sequentially arranged in the conveying direction of the battery conveyor. According to the device and the method, welding strips are pressed by the pressing positioning clamp while being placed, so that the welding strip are prevented from shifting in the conveying process, and the yield of battery strings is greatly improved.

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 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 can allow wider metal g...
