Embodiment Construction

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

[0056] like 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 sheet A...

Abstract

The invention discloses an IBC solar battery serial light welding device and a welding 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 includes a machine frame, a welding ribbon feeding device, a welding ribbon transferring device, a light welding device, a clamp reflow device, a battery conveyor, a clamp conveyor and a pressing positioning fixture. The gripper conveyor is located on one side of the battery conveyor. The ribbon feeder is located below the output of the gripper conveyor. The ribbon transfer device is located above the input of the battery conveyor and the output of the gripper conveyor. Ribbon transfer device, light soldering device, and jig reflow device are arranged in sequence along the conveying direction of the battery conveyor. In the present invention, by pressing the welding ribbon with a pressing and positioning fixture while placing the welding ribbon, the displacement of the welding ribbon during transportation is avoided, and the good product rate of the battery string 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 wire. 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 gr...
