Copper base belt surface treatment device of solar photovoltaic welding belt and processing method thereof

Abstract

The invention discloses a copper base belt surface treatment device of a solar photovoltaic welding belt. The device can be used in a solar photovoltaic welding belt production line and installed behind rolling equipment and in front of rolling-up equipment. The device comprises an annealing and cooling device, a surface cleaning and drying processing device and a straightening device. The invention also discloses a processing method using the copper base belt surface treatment device. According to the processing method, the copper base belt is rolled by the rolling equipment and then annealed and cooled by the annealing and cooling device; the copper base belt after being annealed and cooled enters into the surface cleaning and drying processing device for surface cleaning and drying; the copper base belt after being cleaned and dried enters into the straightening device for improving the straightness; and the copper base belt after being straightened enters into the rolling-up equipment for rolling up. By adopting the device and the method, wires can be cleaned in real time, weldability of the copper base belt can be improved, tinplating rejection rate caused by the poor surfacequality of the copper belt can be reduced and the problems such as the poor straightness of the copper base belt and the like can be solved.

Description

technical field [0001] The invention relates to a surface treatment device and a treatment method, in particular to a copper base strip surface treatment equipment and a treatment method for solar photovoltaic welding strips. Background technique [0002] With the development of new energy in China and the application of solar photovoltaic power generation, the production of solar photovoltaic welding ribbon has been greatly promoted. The solar photovoltaic ribbon connects the solar cells in series and is an important component for energy transmission in the solar cell module. Solar photovoltaic ribbons, which are widely used in the solar module manufacturing industry at present, are manufactured by main processes such as wire drawing, calendering and tin plating. [0003] The manufacturing process of the solar photovoltaic ribbon includes the step of annealing and cooling the copper ribbon. Today's cooling devices are extremely simple, consisting of only one cooling tank....
