[0002] The existing developing machine rinses the sample after ultraviolet exposure with a solution to dissolve the glue on the surface of the sample and make the circuit board circuit visible, but the solution does not dissolve the photosensitive layer on the circuit board completely and the dissolution speed is slow, which affects the development effect. Among them, the "circuit board developing device" disclosed with application number "CN202211316140.0" is also an increasingly mature technology. A pair of spray heads are set to evenly spray the developing solution on the circuit board, and then the circuit board is brushed by a scrubbing roller to remove the residual photosensitive layer. The circuit board is then cleaned by a pair of spray heads and the moisture is removed by a scrubbing roller. The circuit board is then dried by a drying module, which ensures the thorough dissolution of the photosensitive layer and increases the development efficiency. However, the device also has the following defects: the dissolved glue is easy to stick to the surface of the sample during the cleaning process, and it is difficult to clean the surface glue with a simple rinse and hang removal, and the cleaning effect is limited.
