Triangular welding strip production system, tin coating device thereof, air knife system of tin coating device and air knife of air knife system

Abstract

The invention discloses a triangular welding strip production system, a tin coating device thereof, an air knife system of the tin coating device and an air knife of the air knife system. The air knife comprises a body, the body is internally provided with two independent air cavities, each air cavity is provided with an air knife air inlet communicating with the air cavity, and each air knife airinlet is used for being connected with an air source; and each air cavity is further provided with an air knife air outlet. The body is internally provided with an air knife partition piece which divides the space in the body into the two independent air cavities, and the air knife air outlets of the two air cavities are adjacent. Aiming at wire rods of a segmented triangular welding strip, whenthe wire rods are coated with tin, tin layers can be scraped with different air force for parts in different section shapes, and thus, it is ensured that the tin layers at the parts in the different section shapes are uniform.

Description

technical field [0001] The invention relates to the field of triangular welding strip production equipment, in particular to a triangular welding strip production system, a tin coating device, an air knife system and an air knife. Background technique [0002] Photovoltaic soldering strips, also known as tinned copper strips or tinned copper strips, are divided into bus strips and interconnection strips, and are used for the connection of photovoltaic module cells. Ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the ribbon will directly affect the current collection efficiency of photovoltaic modules and greatly affect the power of photovoltaic modules. [0003] The welding ribbon must be firmly welded in the process of connecting the cells in series to avoid the occurrence of false welding and false welding. The production process of welding strip usually includes important steps such as rolling forming, annealing, flux co...

AI Technical Summary

Problems solved by technology

The air knife used in the existing triangular welding strip production system is usually a single-layer air knife, which can only meet the production requirements of the entire section of the triangular welding ribbon, and the tin coating effect on the segmented triangular welding ribbon is not good, which affects the quality of the welding ribbon
