Automatic spraying device for circuit board

The utility model discloses an automatic spraying device for a circuit board, which comprises a machine table, at least one load bearing seat, a three-dimensional moving material clamping group, a three-dimensional moving spraying group, a conveyer belt and a drying case. The machine table is at least provided with a conveying drying layer and a spraying turnover layer from bottom to top lengthways; the three-dimensional moving material clamping group is used for clamping and moving a circuit board back and forth between the two layers, and is matched with the three-dimensional moving spraying group, the conveyer belt, the drying case and other equipment for spraying, turning-over, delivering and drying the circuit board sequentially, so that the automatic spraying operation can be realized, and the uniformity of spraying thickness, the consistency of spraying quality and the utilization rate of the space of the machine table can be improved.
