Thin film solar cell bus bar intersection automatic hot welding device

Abstract

The invention relates to a thin film solar cell bus bar intersection automatic hot welding device and belongs to the field of semiconductor welding equipment. The device comprises a thin film solar cell transmission positioning mechanism, wherein a wire feeding sliding plate driven by a linear driving mechanism is arranged above the transmission positioning mechanism, a welding wire wheel is arranged on the wire feeding sliding plate in a rotary model through a shaft, a welding presser foot is arranged above a thin film solar cell bus bar intersection and is driven by the linear driving mechanism, and a welding gun is arranged on a welding gun sliding plate driven by a welding gun sliding plate linear driving mechanism. In a welding process, the linear driving mechanism of the wire feeding sliding plate drives the wire feeding sliding plate to send a welding wire to the intersection, the linear driving mechanism drives the welding presser foot to be pressed on the welding wire, the linear driving mechanism of the welding gun sliding plate drives the welding gun on the welding gun sliding plate to reach to the intersection, and then hot welding is achieved. The thin film solar cell bus bar intersection automatic hot welding device is good in welding quality, high in welding speed, applicable to large-scale thin film solar cell production, and capable of effectively improving product quality and production efficiency.

Description

technical field [0001] The invention relates to a solar cell bus bar intersection welding device, in particular to an automatic heat welding device for a thin film solar battery bus bar intersection, which belongs to the field of semiconductor welding equipment. Background technique [0002] After the light energy of thin-film solar cells is converted into electrical energy, the electrical energy needs to be collected and exported through the corresponding bus bars. Usually, two vertical strips are used to confluence the electrodes at both ends, and then connected to the junction box through two horizontal conductive strips as positive and negative electrodes. Leading out, the intersection point should be formed between the vertical belt and the horizontal belt, and the welding of the intersection point has a relatively important influence on the performance and life of the thin film battery. Material, the confluence strip is aluminum strip and aluminum-nickel strip respecti...
