Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic welding strip processing, and particularly relates to a device for removing soldering flux from the surface of a welding strip. Background Art

[0002] Soldering ribbon is mainly used as a welding material on photovoltaic modules, and its main function is to connect and conduct electricity. The quality of soldering ribbon is distinguished from many aspects, mainly the comprehensive evaluation of solderability, tensile strength, elongation, resistivity and other aspects. The processing equipment of soldering ribbon is mainly to evenly coat a tin layer on the copper ribbon for use during welding. In order to make the bond between the copper ribbon and the tin uniform and firm, and to reduce the participation of impurities, the copper ribbon needs to be coated with a layer of flux before coating the tin layer. The flux can remove impurities on the surface of the copper ribbon and help to combine the lattice of copper molecules with the lattice of tin molecules. However, if the residual amount of flux is too much deposited on the surface of the copper ribbon, it will cause serious corrosion to the surface of the copper ribbon over time, so that more pinholes will be generated on the surface of the copper ribbon when tin coating. Therefore, a device for removing flux from the surface of the soldering ribbon is needed.

[0003] Prior art CN218517883U discloses a flux blowing device for a photovoltaic stringer. The device includes an air storage chamber connected to an air inlet and an air outlet pipe. The air inlet pipe is connected to a reducer. There are at least three air outlet pipes, each equipped with an air pressure valve. A brush assembly is connected to the outer edge of the outlet end of each air outlet pipe. The air inlet pipe is connected to the connecting air pipe of the stringer solenoid valve control console. After the copper substrate is coated with flux, this device is not easy to fully remove excess flux remaining on the copper substrate surface, which can easily cause corrosion and damage to the copper substrate surface, reducing the efficiency of photovoltaic ribbon production and processing, and greatly reducing its practicality.
