Tinned copper belt production line for solar cell module

Abstract

The invention relates to a tinned copper belt production line for a solar cell module, and the production line sequentially comprises a feeding mechanism, a bright annealing furnace, a calendar, a tinning furnace and a winding machine in a feeding direction. The production line employs the automatic feeding mechanism to replace manual regulation for feeding, and guarantees the production efficiency and quality. A tin furnace in the tinning equipment employs an inclined bottom design. Because there is temperature difference between tin and water, stannic oxide can move to a low temperature side far from a heating part, and flows to a residue collection basket for collection, thereby guaranteeing the production quality. The winding machine in the production line serves as a compound winding detection device, is simple in structure, is easy to operate, can quickly and accurately detect whether a tinned copper belt has impurities or not, and guarantees the quality of a tinned copper belt.

Description

technical field [0001] The present invention relates to a solar cell assembly welding material production line, more particularly, to a solar cell assembly tinned copper strip production line. Background technique [0002] In the existing photovoltaic welding material production line, the design of some equipment structures has the following defects: [0003] First, the feeding mechanism is usually manually regulated for feeding, resulting in low production efficiency and unstable quality; [0004] Second, the existing tin furnace equipment cannot remove impurities. However, when heating the tin water in the tin furnace, after a long time of heating, tin oxide will be generated, which will cause impurities in the tin water. If you do not try to remove the impurities, the impurities will have It may be plated on the copper tape together with the tin water, affecting the quality of the tinned copper tape; [0005] Third, in the prior art, after the copper tape is tinned, the...

Problems solved by technology

[0003] First, the feeding mechanism is usually manually regulated for feeding, resulting in low production efficiency and unstable quality;

[0004] Second, the existing tin furnace equipment cannot remove impurities. However, when heating the tin water in the tin furnace, after a long period of heating, tin oxide will be produced, which will cause impurities in the tin water. If the impurities are not removed, the impurities will be It may be plated on the copper strip together with tin water, affecting the quality of the tinned copper strip;

[0005] Third, in the prior art, after the tinning of the copper strip is completed, the tinned copper strip must be rewound and packaged, but it is inevitable that some impurities will be plated on the copper strip together during the production process, resulting in hidden dangers in the quality of the copper strip
