PCB vacuum etching mechanism

The utility model provides a PCB vacuum etching mechanism which comprises a processing table, a rotating plate and a bending pipe, a first motor is fixed at the upper end of the processing table, fixed universal balls are symmetrically arranged on the left side and the right side in the processing table, an annular groove is formed in the annular side face of the rotating plate, and electric telescopic rods are longitudinally installed on the left side and the right side of the lower end of the rotating plate. Motor sleeves are fixed to the lower ends of the two electric telescopic rods correspondingly, second motors are fixed into the two motor sleeves correspondingly, the lower ends of the two second motors are connected with two fixing columns through connecting shafts, and a plurality of partition plates are arranged on the annular side faces of the two fixing columns at equal angles; by means of the design, the problems that an original device needs to blow-dry or wipe-dry the PCB after etching and clean
