Automatic tin soldering device of multiply-connected basal plate

The invention relates to an automatic tin soldering device of a multiply-connected basal plate. A position induction unit comprises a first induction module for inducing the position of a driving basal plate tin soldering unit, and a second induction module for inducing the position of a driving multiply-connected basal plate moving basal plate; after the tin soldering of one basal plate in the multiply-connected basal plate is finished, a second driving module drives a basal plate loading unit to move; the second induction module induces the position of a next basal plate in the multiply-connected basal plate on the basal plate loading unit; after the second induction module determines that the next basal plate on the basal plate loading unit is in place, a tin soldering unit solders the multiply-connected basal plate; and the operations are repeated until the tin soldering of all basal plates on the basal plate loading unit is finished. As the automatic equipment operation is adopted, the automatic tin soldering of the multiply-connected basal plate is realized, the tin soldering quality is guaranteed, such defects as weak quality, continuous soldering and bad soldering in the tin soldering of the multiply-connected basal plate are eliminated, the tin soldering time is largely shortened, and high-temperature gummed papers used in the tin soldering process are cancelled to reduce the cost.
