Description

Technical Field

[0001] The utility model relates to the technical field of tinning devices, in particular to an automatic tinning device for multi-line photovoltaic welding strips. Background Art

[0002] The photovoltaic ribbon tinning device is used to tin copper wire after annealing. Application number 202311529226.6 is a photovoltaic ribbon tinning device, comprising a tin liquid storage mechanism, a tinning mechanism mounted on the tin liquid storage mechanism, and a leak prevention mechanism mounted on the tinning mechanism. As the motor starts and runs, the shaft at the inner end of the motor drives the track to rotate. At this time, the drive roller and three auxiliary rollers, which are clamped by multiple external frames, continuously deliver the copper strip to the inner cavity of the tin guide bin. Guided by the auxiliary shaft, the actively delivered copper strip is fully coated with the tin liquid in the inner cavity of the tin guide bin. When the tinned copper strip moves to the internal slot of the cooling cover, multiple turbine blades driven by the external drive track and motor blow external airflow to the tinned copper strip for short-interval cooling, thereby ensuring the copper strip is tinned in a short-interval manner while preventing the tinned copper strip from vibrating during the cooling and solidification period. The tin coating device can only process individual copper wires sequentially and has no tin blowing structure, resulting in uneven tin coating on the surface of the processed copper wire, which affects the cost effect.
