This utility model discloses an immersion plating solution supply device, comprising: a transfer container for temporarily storing the immersion plating solution; a stirring motor and a liquid inlet located at the top of the transfer container; a stirring shaft located in the transfer container and driven by the stirring motor; a stirring rod located in the transfer container and driven by the stirring shaft; an ultrasonic
transducer located at the bottom of the transfer container; a supply
pipe externally connected to the bottom of the side wall of the transfer container for conveying the immersion plating solution to the immersion plating treatment container; and a supply valve and a supply pump located on the supply
pipe. This immersion plating solution supply device can pre-stir and ultrasonically treat the immersion plating solution before adding it from the packaging container to the immersion plating treatment container, thereby eliminating or significantly reducing agglomeration and
sedimentation of the immersion plating solution. Furthermore, when performing batch immersion plating treatment on aluminum tube substrates, it can avoid or significantly reduce adverse consequences caused by fluctuations in the quality of the immersion plating solution, ultimately improving product yield and reducing production costs.
