Photovoltaic series welding machine and photovoltaic welding strip machining method

Abstract

The invention discloses a photovoltaic series welding machine and a photovoltaic welding strip machining method. The photovoltaic series welding machine comprises a first clamping component used for pulling a welding strip from a welding strip reel, a second clamping component used for being matched with the first clamping component to stretch the welding strip, a cutting component used for cutting the welding strip, and a first electrode and a second electrode used for supplying power to the welding strip. According to the photovoltaic series welding machine provided by the invention, the first electrode and the second electrode are additionally arranged on the photovoltaic series welding machine, and the cut welding strip is electrified and annealed, that is, the welding strip is annealed before a battery piece is welded, so that the current type annealing time is short, the efficiency is high, an electrifying measure is added before the welding strip is carried, the operation is simple and convenient, and other time cost and labor cost are not brought.

Description

technical field [0001] The invention relates to the field of photovoltaic ribbons, in particular to a photovoltaic stringer and a processing method for photovoltaic ribbons. Background technique [0002] At the present stage, dense grid modules (represented by 9 grids) have gradually become the mainstream photovoltaic module products, and major companies have launched corresponding dense grid products, and many photovoltaic module manufacturers have the ability to mass produce. In the current material matching, the dense grid components basically use round wire ribbons as the interconnecting strips. In the process of using automatic welding, part of the action of the stringer is to pull the ribbon - clamp the ribbon - stretch the ribbon - cut the ribbon - transport the ribbon. In this continuous process, the stretching of the ribbon The purpose of the action is to make the ribbon drawn from the reel change from a bent state to a state with a certain straightness, which is c...
