Description

[0003] The patent application with announcement number CN217693907U proposed in the prior art can clamp the PCB board during the conveying process by adopting a locking frame that moves in opposite directions, and maintain the circuit board in a flat position on the feeding table during hot air drying to prevent the circuit board from being blown by the airflow and causing poor drying effect. A vertically movable dust cover is used to bring the foam pad close to the plane of the feeding table during the drying process, and the elastic material of the foam pad is used to squeeze it on the upper end of the locking frame. When the circuit board is blown, it collides with the foam pad to prevent the circuit board from jumping out of the locking frame. The pore structure of the foam pad makes the hot air flow blow out more evenly and slowly.
