Ultrasonic wave FPC washing machine

The utility model relates to the field of FPC manufacturing field, in particular to an ultrasonic wave FPC washing machine which comprises an ultrasonic wave rough washing groove. An outlet end of the ultrasonic wave rough washing groove is connected with an ultrasonic wave fine washing groove. An outlet end of the ultrasonic wave fine washing groove is connected with a performed groove. An outlet end of the preformed groove is connected with a slowly-pulling drying groove. A cooling system is further included. The cooling system is arranged above the ultrasonic wave rough washing groove, the ultrasonic wave fine washing groove, the preformed groove and the slowly-pulling drying groove. The cooling system, the ultrasonic wave rough washing groove, the ultrasonic wave fine washing groove, the preformed groove and the slowly-pulling drying groove form a sealed cavity. According to the washing machine, materials can be washed automatically, washing efficiency is greatly improved, the surface of the materials is completely washed by two-level washing, small impurities on the surface of the materials can be effectively removed, accordingly, the combining intensity of an element and an FPC bonding pad is improved, then the quality of a final finished product is improved, the cooling system cools grooves in the washing machine, and stable operation of the washing machine is guaranteed.
