Problems solved by technology
The above-mentioned slitting and tin coating are in different processes. The slitting copper strip needs to be coiled with a turntable, and then uncoiled when tin coating, resulting in a longer production process.
In addition, the rewinding length of the revolving disc is limited during slitting, generally not exceeding 300 meters; every time the tinning is performed, the belt needs to be threaded, and the belt must be stopped when the belt is threaded, and the tinning is started after the belt is threaded. During the transition process from zero speed to normal production speed, every time the machine is started, copper and pinholes appear on the head of the welding ribbon for dozens of meters and cannot be used. Not only the yield rate is low, the waste is serious, but also the production efficiency is very low.
In addition, the copper removal method of the tin furnace adopts the method of intermittent cooling and slag removal, and the copper content in the surface coating of the tin-coated solder strip cannot be stably controlled

The invention relates to a tin-plated welding strip production device for a solar photovoltaic component, and belongs to the technical field of solar photovoltaics. The device comprises a discharge system, a slitting system, a tin plating system, a strip storage system and a non-stop plate replacing strip reeling system. A rinsing tank, a water blowing air knife, a soldering flux groove, a hot air knife, a solder machine, a cooling air knife and a driving roller pair are sequentially arranged along the welding strip advancing direction in the tin plating system. The strip storage system comprises fixed pulley blocks, a free pulley block, a counterweight pulley, a balancing weight and a plurality of groups of independent strip storage mounting seats. Each group of independent strip storagemounting seat is provided with an independent strip storage pulley block. Welding strips sequentially pass through the fixed pulley blocks and the free pulley block, and then enter own independent strip storage pulley blocks. In the independent strip storage pulley blocks, each welding strip sequentially passes through independent strip storage fixed pulleys and independent strip storage free pulleys, enters a strip storage outlet pulley block and enters the non-stop plate replacing strip reeling system from the strip storage outlet pulley block. By the production device, a production procedure is shortened, and yield is increased.
Description
technical field [0001] The invention relates to a production device for solar photovoltaic components, in particular to a production device for tin-coated soldering strips for solar photovoltaic components, which belongs to the technical field of solar photovoltaics. Background technique [0002] Photovoltaic power generation is in the ascendant, and tin-coated ribbon is one of the key components for welding crystalline silicon cells and leading out the electricity generated by solar cells, which requires good electrical conductivity and solderability. [0003] The production process of tin-coated solder strip generally adopts copper strip slitting or rolling method to produce flat copper strip with round copper wire, and then tin-coated. The above-mentioned slitting and tin coating are in different processes, and the slitting copper strip needs to be coiled with a turntable, and then uncoiled when tin coating, resulting in a longer production process. In addition, the rewi...
