Photovoltaic tandem welder with ultraviolet curing function

Abstract

The invention provides a photovoltaic tandem welder with an ultraviolet curing function. The photovoltaic tandem welder comprises a welding band horizontal straightening device, a welding band stretching device, a tandem welder body, a high reflection film spraying device and an ultraviolet curing device, wherein the high reflection film spraying device and the ultraviolet curing device are installed behind the welding band horizontal straightening device and before the welding band stretching device, and the high reflection film spraying device and the ultraviolet curing device are fixedly installed on the tandem welder body; a circuit of the high reflection film spraying device is connected with an intelligent computer of the tandem welder body by electric wires; and a circuit of the ultraviolet curing device is connected with the intelligent computer of the tandem welder body by electric wires. According to the photovoltaic tandem welder, the high-reflection film spraying device andthe ultraviolet curing device are installed between the welding band horizontal straightening device and the welding band stretching device of the tandem welder body, so that a high reflection film is plated on a battery welding band, the performance of the welding band is improved, and the welding quality is improved; and meanwhile, the normal operation of the tandem welder is not affected, andthe power generation efficiency of a battery piece is improved.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cell welding, in particular to a photovoltaic string welding machine with an ultraviolet light curing function. Background technique [0002] The stringer is an important equipment for producing solar photovoltaic modules in the photovoltaic industry. It connects single silicon cells in series to increase the output voltage and power, and performs precise welding with the welding ribbon with excellent conductivity under infrared high temperature conditions. The existing string welding machine only has the function of welding the cells between the cells through the welding ribbon. The string welding machine can only complete the simple welding process of cell-welding strip-cell, and the welding raw materials must be processed and processed. Completed cell and ribbon. For cells and ribbons that have not undergone pretreatment, the next step cannot be processed, which is not conducive to improv...
