Embodiment Construction

[0013] This specific embodiment adopts the following technical solutions: it uses rolling and tin-coating process to process separately; oxygen-free copper wire rolling process: rolling→quenching→nitrogen treatment→deionized water cleaning→copper strip winding.

[0014] Oxygen-free copper strip tin coating process: Copper strip feeding → cleaning system → soldering system → preheating and air drying → tin coating → coating thickness adjustment → receiving → cutting and packaging.

[0015] The oxygen-free copper wire rolling process adopts 99.99% oxygen-free copper as the main material, adopts the rolling-quenching process, and the current is controlled by the contact surface between the copper strip and the rolling equipment to form resistance, generate heat, and meet the requirements of the quenching process. The physical properties of the copper strip reach a super soft state; after the rolling and quenching process, a nitrogen treatment process is added to stabilize the phys...

Abstract

The invention discloses a novel photovoltaic welding strip production process and relates to the field of solar photovoltaic power generation systems. A calendering process and a tin coating process are adopted for separate treatment, wherein the oxygen-free copper line calendering process comprises the steps of calendering, quenching, nitrogen treatment, deionized water washing and copper strip winding; and the oxygen-free copper strip tin coating process comprises the following steps of copper strip unwinding, cleaning through a cleaning system, welding aid through a welding aid system, preheating and air-drying, tin coating, coating thickness adjustment, material receiving, and cutting and packaging. The novel photovoltaic welding strip production process has the advantages that the quenching process requirement can be satisfied, the physical properties of copper strips are changed, the copper strips can reach an ultra-soft state and the production efficiency is greatly improved; and by adopting a separate treatment method, the coating thickness in the copper strip tin coating process can be better controlled, the product quality is better controlled during production and the process flexibility is increased.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation systems, in particular to a manufacturing process of a novel photovoltaic welding strip. Background technique [0002] Photovoltaic welding ribbon is a kind of battery pack accessories in solar photovoltaic power generation system. The country's extensive use of solar energy has led to the explosive growth of the photovoltaic industry. Photovoltaic welding ribbons have also become the fastest growing downstream demand in the field of battery pack accessories. [0003] 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. [0004] 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. Manufacturers m...
